Next, with reference to the drawings will be described technologically advanced, the cue cartridge (which will be referred to below as the "cartridge") and electrophotographic device to form the image (which will be referred to below as the "device imaging") in the first preferred the embodiments of the present invention.

The overall design of the device forming images

First, with reference to figure 1, will be described device imaging in this embodiment, in relation to its overall design. The device 100 forming the image shown in figure 1, has four compartments 22 (22A-22d) for ink cartridges, there is a space in which one after another set of four cartridge (figure 3). Four compartment 22 (22A-22d) of cartridges are placed side by side (in parallel) in one straight row at an angle relative to the horizontal direction. The cartridge 7 in each compartment 22 (22A-22d) for cartridge has one electrophotographic photosensitive drum 1 (1A-1d).

Electrophotographic photosensitive drum 1 (which may be referred to below as the "photosensitive drum") is driven into rotation in the clockwise direction according to the drawing by a driving element (not shown). Each cartridge 7 has the following processing means which are arranged around the peripheral surface of the photosensitive drum 1 in such a way that surround the photosensitive drum 1, in the order in which they will be listed below. This is the cleanser 6 (6A-6d), which removes the developer (to the which may be referred to below as "toner"), remaining on the peripheral surface of the photosensitive drum 1 after the transfer, the charging roller 2 (2A-2d), which uniformly charges the peripheral surface of the photosensitive drum 1, the scanner unit 3, which forms an electrostatic latent image on the peripheral surface of the photosensitive drum 1 by emitting a beam of laser light with a simultaneous modulation of the beam of laser light of the image information, a developing unit 4 (4A-4d), which shows the electrostatic latent image on the peripheral surface of the photosensitive drum 1 with the toner and the intermediate transfer belt 5, which sequentially, one after the other, four images are transferred, shown by the toner, which vary in color. The photosensitive drum 1, charging roller 2 and the developing unit 4 is made as a single unit in the form of a cartridge (process cartridge), i.e. the cartridge 7, which the user sets with the possibility of removal in the primary host 100A device 100 form the image.

The intermediate transfer belt 5 is stretched around a driving roller 10 and a tension roller 11, and is supported by them due to this. The primary site 100A device 100 imaging provided with rollers 12 (12A-12d) of the first transfer, which find the I on the inner side of the closed path, formed by the intermediate transfer belt 5. The rollers 12 of the first transfer set so that they are arranged one after the other opposite the photosensitive drum 1 (1A-1d). The means of application of bias (not shown) applies to the transfer belt 5 offset migration.

After forming the image shown by the toner on the photosensitive drum 1 of the image shown by the toner is transferred onto the intermediate transfer belt 5. More specifically, four images shown by the toner, one after the other are formed on the four photosensitive drums 1. Then, when the four photosensitive drum 1 rotates further in the direction indicated by the label Q in the form of arrows, and the intermediate transfer belt 5 rotates in the direction indicated by the label R in the form of arrows, four images shown by the toner, individually transferred (first transfer) onto the intermediate transfer belt 5 due to the positive bias applied to the rollers 12 of the first transfer. Then four layers of images shown by the toner and distinguished by color on the intermediate transfer belt 5 is transferred to the second transferring section 15.

The contact surface 40h and positioning the first sections 40A (a and a) cartridge, are the areas of the peripheral surface of the first support 40. Further, the cartridge 7 has a second bearing 50, which supports the other of the longitudinal (in the sense of the direction of movement parallel to the axial line of photosensitive drum 1) the end of the photosensitive drum 1. Pin chirouse section 50h (contact surface) and second positioning sections 50A (a and a) cartridge, are the areas of the peripheral surface of the first support 40.

Therefore, it is guaranteed that the cartridge 7 is accurately positioned relative to the primary node 100A.

Just like positioning section 40A of the cartridge, that is, the positioning portion of the cartridge on the rear side positioning section 50A of the print cartridge has a positioning section of the cartridge positioning third phase a cartridge), which is located on one side of the axial line of the photosensitive drum 1, and a positioning section of the cartridge positioning fourth plot a cartridge), which is on the other side of the axial line of the photosensitive drum 1. Positioning the third section a cartridge positioning area on the side of the front end) is on the opposite side above the centerline of I from the positioning of the fourth sector a cartridge positioning portion at the rear end) (Fig). As for the above-mentioned detecting the pressure section 50b, it is on the side of the photosensitive drum 1, which is located "behind-the-go" in the sense of the direction of advancement of the cartridge. When viewed from the direction To (11(C)), which is directed upward pressure is applied through the above-mentioned pull-down element 93 (applied pressure element, push up e is ementa), then catching the pressure element 50b is approximately in the middle) positioning between the third and fourth sections a and a cartridge. Therefore, when exposed to a clip on the safety pressure section 50b, the positioning sections 50A cartridge is tightly pressed on detecting the pressure section 92A, resulting in a correctly positioned relative to the primary node 100A.

In this embodiment, the cartridge 7 is provided with positioning the third and fourth sections a and a cartridge as positioning sections of the cartridge-side front end. Because it is guaranteed that the cartridge 7 is reliably pressed against the arresting pressure sections 92A primary node 100A. However, the number of positioning sections of the cartridge, which is provided with the rear end of the cartridge 7 may be equal to only one, provided that it ensures the proper positioning.

In addition, the cartridge 7 is provided with a buoyancy element 50C, which is the second pushing element to move the pull up element 93 in its allotted position. With respect to the center of the cartridge 7 in terms of the horizontal direction perpendicular to the aforementioned direction of advancement of the cartridge eject section 50C is closer to the wall continue the aqueous end of the cartridge 7, than catching pressure section 50b. Eject section 50C is ahead on the fly" from the wall of the primary (in the sense of the direction of advancement of the plot supports 50 of the cartridge 7, and its tail section provided with a projection 50d, which acts downwards. More specifically, the projection 50d is beveled, thereby providing a smoothly inclined surface 50 ppm and 50f, that is, the inclined surface on the sides, located "ahead of in the course of" and "behind-the-go", respectively, which are inclined so that their intersection is a vertex of the projection 50d (projection 50d). In addition, the support 50, that is, the bearing on the rear side, provided with a second contacting section 50h (contact surface, which serves as governing the movement section of the cartridge), which is further up than the positioning section 50A of the cartridge. The second contacting section 50h is flat across the top surface (second contact surface) and is located between one end of the third positioning area a cartridge and the other end of the fourth positioning section a cartridge. That is, the second contact surface 50h is positioning between the third and fourth sections a and a cartridge; positioning the third section a cartridge is located at one end of the second contact is yuusei surface 50h, and positioning the fourth section a cartridge is located at another end of the second contact surface 50h. Behind-the-go (in the sense of direction of the ink cartridge is installed) from the second contact surface 50h is the surface 50g, which is closer to the axial line of the drum 1 with light-sensitive surface layer than the top surface of the second contact surface 50h.

In addition, in terms of the direction perpendicular to teach line of the photosensitive drum 1, the upper surface (the area of the first contact of the contacting section 40h different position from positions of the first sections 40A (a and a) cartridge. In addition, in terms of the direction perpendicular to the axial line of the photosensitive drum 1, the upper surface (the area of the second contact) differs in position from the second positioning sections 50A (a and a) cartridge.

Further, in the above sense of the direction of advancement of the cartridge, the upper surface (the region of first contact of the first contact section 40h is on the side of the front end, and the upper surface (the area of the second contact, the second contact section 50h is on the side of the rear end.

Therefore, it is guaranteed that the cartridge 7 is accurately positioned relative to the primary node 100A. Next, in the sense direction, perpendicular to the axial line of the photosensitive drum 1, the upper surface of the contacting section 40h is located between one end of the positioning sections 40A (a and a) cartridge and the other end of the positioning sections 40A (a and a) cartridge. In addition, in terms of the direction perpendicular to the axial line of the photosensitive drum 1, the upper surface (contact area) of the second contacting section 50h is located between one end of the second positioning sections 50A (a and a) cartridge and the other end.

Therefore, it is guaranteed that the cartridge 7 is accurately positioned relative to the primary node 100A.

Next will be described the construction of the positioning of the cartridge section of the base node 100A and clamping the cartridge mechanism of the primary node 100A. Figure 5 presents a schematic drawing for describing the structure positioning the cartridge section of the base node 100A device 100 of the image forming and clamping the cartridge mechanism of the primary node 100A, and to illustrate their designs. Figure 6 presents a detailed drawing of the positioning of the cartridge section and clamping the cartridge mechanism on the rear side, illustrating their design. Figure 7 presents a detailed drawing of the positioning of the cartridge clamping mechanism and the cartridge fur the ISM on the front side, illustrating their design.

As shown in figure 5, the primary host 100A is equipped with rear side panel 82, which is located on the side of the front end in terms of the installation direction of the toner cartridge and the front side panel 92, which is located on the side of the rear end. The side panel 92 provided with an aperture through which the cartridge 7 is set with the possibility of removal in the compartment 22 to the cartridge. The cartridge 7 is inserted into the primary site 100A through this opening. Further, the cartridge 7 is inserted into the compartment 22 to the cartridge in the direction marked F in the form of arrows along above the upper rail 80 to the direction of the cartridge and the lower guide 81 to the direction of the cartridge (figure 3).

The side panel 82 is equipped with two safety cartridge plots a (a and a), that is, the first sections of the primary node, which is intended to correct (in the sense direction perpendicular to the direction (the direction of advance), which set the cartridge 7) positioning the cartridge 7 relative to the primary node. The side panel 82 is also provided with a clamping element 83, which is designed to clamp the cartridge 7 for detecting the cartridge section a, under pressure applied thereto due to the elasticity of the elastic force) of the compression springs 85. This clamping element 83 functions as a push kV is the Rhu village, it is the element, which holds the cartridge 7 is pressed upward by pressing upward by the pressure applied by the compression spring 85.

Clamping element 83 is under catching cartridge plot a. It is attached to the side panel 82. More specifically, the axis 84, rigidly attached to the side panel 82, that is, the sidebar on the rear side of the primary node, is inserted through the through hole 83A, the axial line of which coincides with the axis of rotation of the clamping element 83 so that it is guaranteed occupation of the holding element 83 the position of the clamping cartridge, in which he holds the cartridge 7 is pressed on catching the cartridge sections a; its allotted position in which it does not press the cartridge 7; and the provisions of waiting, in which he remains on the trajectory of the cartridge 7.

Further, the holding element 83 is supplied eject the cartridge section 83b through which the clamping element 83 pushes the cartridge when the clamping element 83 is in the position of clamping of the cartridge. Eject the cartridge section 83b position corresponds to detecting the pressure section 40b of the cartridge 7. Clamping element 83 is also provided with detecting the pressure of the first section 83 C get to move the clamping element 83 in the designated position. Detecting the pressure of the first area corresponds to 83 C get put on the Yu eject section 40C of the cartridge 7. Detecting the pressure of the first section 83 C get equipped directed upward projection 83d. This directed upward protrusion 83d provided with smoothly sloping surfaces e and 83f, which are located "behind on the go and ahead along the surfaces of the ledge 93d, respectively, in the sense of direction of the ink cartridge is installed. Surface e and 83f tilted so that the connection between these two surfaces is the top of the ledge 83d. In addition, in terms of the direction perpendicular to the mounting direction of the cartridge detecting the pressure plot 83 C get is farther out (in terms of the radial direction of the hole 83A) from the centerline of the hole 83A than eject the cartridge section 83b. That is, in terms of the longitudinal direction of the clamping element 83, above the axial line of the hole 83A, clamping the cartridge section 83b and catching pressure section 83 C get are arranged in the order listed.

The side panel 82 is provided with a control movement of the first cartridge section 86 (governing the movement of the cartridge first site primary node), which prevents the movement of the cartridge 7 upwards under the action of the reaction force generated when the cartridge pushes the clamping element 83 in its allotted position. Governing the movement of the cartridge of the first section 86 vypolnenij polymer and is located between the two catching cartridge plots a (a and a) side panel 82.

As shown in Fig.7, the side panel 92 provided with an aperture 92b for inserting the cartridge and catching two cartridge sections 92A (a and a), which function as positioning the second cartridge sections of the primary node. Catching the cartridge sections 92A are two sections, the upper section of the inner surface of the opening 92b and are for the correct positioning of the cartridge 7 in terms of the direction perpendicular to the mounting direction of the cartridge. Further, the side panel 92, that is, the front side panel of the primary node is equipped with pulling the cartridge element 93 to pull the cartridge 7 up to catching the cartridge sections 92A due to the application of the tension force, which is applied the pressure of the spring 95, which is the spring tension. Pulling the cartridge element 93 is catching up from the cartridge sections 92A. It is supported can be rotated side panel 92; axis 94 rigidly attached to the side panel 92, is inserted through the hole 93A (axial line which is the axis of rotation) pull the cartridge element 93. This pull cartridge element 93 is attached to the side panel 92 (supported it) is thus guaranteed lesson this item: the position of the clamping cartridge, in which he holds the cartridge 7 is pressed on catching install the j sections 92A; his allotted position in which he does not feel the impact force of the spring 95; and the provisions of waiting, in which he remains on the trajectory of the cartridge 7.

Next, pull the cartridge element 93 is equipped with pulling the cartridge section 93b to pull the cartridge up when pulling the cartridge element 93 is tandem cartridge position. Pulling the cartridge element 93 to position corresponds catching applied to the cartridge pulling force detecting section 50b of the cartridge 7. Pulling the cartridge element 93 is also provided with safety cartridge of the second section 93s to move pull the cartridge element 93 in its allotted position. Catching the second cartridge section 93s position corresponds to the pushing section 50C of the cartridge 7. It has directed upward protrusion 93d, which has a gently sloping surface e and 93f (figure 10), which are tilted so that their intersection is a vertex of the protrusion 93d.

In addition, in terms of the direction perpendicular to the mounting direction of the cartridge catching cartridge plot 93s is located farther outward from the centerline of the hole 93A than pulling the cartridge section 93b. That is, in terms of the longitudinal direction of the pull cartridge element 93, the above-mentioned hole 93A, pulling the cartridge section 93b and catching pressure acartridge plot 93s are arranged in the order listed. Further, the side panel 92, that is, the front side panel of the primary node, is provided with a control movement of the cartridge first section 96, which is designed to prevent movement of the cartridge upward under the action of the reaction force generated when pulling the cartridge element 93 is pushed in its allotted position. Governing the movement of the cartridge section 96 is located between the above two catching cartridge sections 92A (a and a).

In this embodiment, on the rear side (in the sense of direction of the ink cartridge is installed) end of the cartridge 7 applied pressure element 83 (clamping element, push up the item) is below catching the cartridge section 83A, allowing the bottom to push the cartridge up, and this leads to the fact that the cartridge stumbles upon detecting the cartridge parts a, while on the rear side (in the sense of direction of the ink cartridge is installed) end of the cartridge 7 pulling the cartridge element 93 (holding the cartridge element) is located above catching the cartridge sections 92A, allowing the top to pull the cartridge 7 up, and this leads to the fact that the cartridge stumbles upon detecting the cartridge sections 92A, which are located above the cartridge. That is, when the cartridge 7 is moved to its position of formylbenzoate in the primary host 100A, catching the cartridge area a (plot, which operates the clamp) is pressed aimed upward force eject the cartridge element 83. Thus, positioning the first and second a and a cartridge positioning the cartridge parts cartridge on the side of the rear end) are properly positioned by means of positioning the cartridge sections a (positioning the cartridge of the first section of the main site). Next, catching applied to the cartridge pulling force element 50b proceeds directed upward pulling force on the pull up element 93. Therefore, positioning the third and fourth sections a and a cartridge positioning the cartridge parts cartridge on the side of the rear end) are properly positioned by detecting the cartridge elements 92A (a and a) (positioning the second cartridge of the main sections of the site). Thus, the application of this structural arrangement makes it possible to provide the side panel 92, that is, the front side panel of the main unit, an aperture, through which you can install the cartridge 7 into the compartment 22 to the cartridge. Therefore, on the support 50, that is one of the pillars in the vicinity of the positioning section of the cartridge can exert pressure directly. Therefore, the pressure, prikladyvat is passed to the support 50, remains stable. Therefore, the cartridge 7 is accurately positioned and remains accurately positioned. Therefore, the photosensitive drum 1 is exactly in contact with the intermediate transfer belt 5 and remains exactly in contact with the tape 5.

However, one should not consider this option implementation limiting the present invention in design layout. That is, presses the cartridge element 83 can be positioned on the sides of the front and rear (in the sense of direction of the ink cartridge is installed) ends, respectively, as the elastic clamping elements or Vice versa. To obtain the effects described above can be in any of these cases.

Work clamping the cartridge mechanism during installation and removal of the print cartridge

Next, with reference to Fig-11 will be described the operation of clamping the cartridge mechanism during installation of the cartridge 7 in a device of image formation and extraction of the cartridge 7 from the device forming the image.

(a) Side of the front end: the Operation of clamping the cartridge mechanism during installation and removal of the print cartridge

On Fig presents a view in plan of the right side (when viewed from the front side) of the rear clamping the cartridge mechanism of the primary node. Figure 9 presents a view in plan of the rear side (the rear side (in the thought of the installation direction of the cartridge) end) rear clamping the cartridge mechanism of the primary node.

The cartridge 7 is to be installed in the direction indicated by the label F in the form of arrows. As shown in Fig(a) and 9(a), when the cartridge 7 is inserted, the inclined surface 40E eject section 40C supports 40, that is, the back support of the cartridge 7, comes into contact with the inclined surface e catching cartridge section 83 C get (stand by position). Then, when the cartridge 7 is inserted further, the holding element 83 is gradually pushed downward, causing the protrusion 40d eject section 40C to come into contact with the projection 83d catching cartridge element 83 C get, as shown in Fig(b). Therefore, the holding element 83 is discharged in the direction indicated by the mark X in the form of arrows (designated position).

More specifically, the holding element 83 is moved to its allotted position in which it presses the section 83b is not in contact with the arresting pressure section 40b of the cartridge 7, as shown in Fig.9(b). Therefore, when the cartridge 7 is set, detecting the pressure section 40b is not exposed to any pressure. The pressure, which perceives the cartridge 7 from the holding element 83, when it is installed, removed eject section 40C, which is located farther from the hole 83A. That is, the amount of force required to push down the holding element 83, providing weather resistance is of force, which operates by ejecting the cartridge 7 up, reduced depending on the ratio of the distance from the centerline of the holes 83A to capture the pressure section 40b (eject section 83b) and the distance from the centerline of the holes 83A to eject section 40C (catching pressure section 83 C get). Therefore, the magnitude of the load, the impact of which is subjected to the cartridge 7, when it is installed, is substantially less than the pressure which the cartridge 7 perceives from the clamping element 83; the amount of force that is necessary for installation of the cartridge 7, is substantially less than the pressure that the cartridge sees from the clamping element 83.

Further, when the cartridge 7 is set, the cartridge 7 is subjected to directed upward forces reaction forces generated when the holding element 83 is pushed down in its allotted position. However, the contact surface 40h comes into contact with the regulating movement of the cartridge section 86, that is in contact with the cartridge, the first section of the main site. Therefore, prevents the movement of the cartridge 7 upwards. At the same time control the movement of the cartridge section 86 of the primary node and in contact with the main site area 40h are positioned so that they remain in contact with each other until the omenta, immediately preceding the correct positioning of the positioning section 40A of the cartridge due to coming in contact with catching the cartridge area a. Therefore, when installing the cartridge 7, more specifically, when the cartridge 7 is beginning to perceive directed upward pressure from the clamping element 83, until the moment immediately preceding the correct positioning of the cartridge 7, and regulating the movement of the cartridge section 86, that is, regulating the cartridge section of the main site, which is made of polymer, and contacting the surface 40h slide over each other, and therefore, the positioning section 40A of the cartridge does not RUB about catching the cartridge area a the primary node, which is made of thin sheet steel or similar material. Therefore, prevents the problem lies in the fact that the positioning section 40A of the cartridge is exposed blade scraping the impact absorbing cartridge area a.

When the cartridge 7 is inserted further, catching the cartridge section 83 C get disengages from the pushing section 40C, and therefore clamping element 83 is gradually returned from the designated position in its position clamp. Then, when the cartridge 7 is inserted far enough so that the contact surface 40i, which think the mA for the correct positioning of the cartridge 7 (in terms of the longitudinal direction of the cartridge 7), could come into contact with the side panel 82, that is, the rear side panel of the primary node, the holding section 83b comes into contact with the receiving pressure area 40b, as shown in Fig(C) and 9(C), causing the cartridge 7 to Nestle (the position of the clamp in the direction indicated by the label J arrow (direction of clamp figure 9). During this process, the positioning section 40A cartridge available in the cartridge 7, hits in catching the cartridge area a rear side panel 82 of the primary node, which leads to the correct positioning of the cartridge 7 in terms of the direction perpendicular to the mounting direction of the cartridge. Also during this process, regulating the movement of the cartridge section 86 of the primary node disengages from contact surface 40h; between regulating the movement of the cartridge section 86 and the surface 40g (recessed surface) creates a gap defined value. At the same time, catching the cartridge section 83 C get moves past the eject section 40C; between catching the cartridge section 83 C get and recessed surface 40j creates a gap specified value.

As described above, clamping the cartridge mechanism has such a structure that the holding element 83 can be in the standby position, the position of the clamp and allotted put the I. More specifically, in the sense of the direction from top to bottom, the stand by position, the position of the clamp and the designated position are in the order listed. Therefore, the holding element 83 applies a pressure of sufficient magnitude to the cartridge 7.

Removing the cartridge 7 from the primary node 100A, the above-described operation of the cartridge is carried out in reverse order. The pressure perceived by the cartridge 7 from the holding element 83 is removed with the push section 40C, which is located farther from the centerline of the hole 83A (axis of rotation)than catching pressure section 40b, when this happens during installation of the cartridge 7. Therefore, the force necessary for removal of the cartridge 7 in this embodiment, is less than the force required for removal of the cartridge 7 in accordance with the prior art, as during installation of the cartridge 7.

However, regardless of installing the cartridge 7 in the primary site 100A or remove the cartridge 7 from the primary host 100A, it is necessary to move the clamping element 83 in the direction perpendicular to the mounting direction of the cartridge. However, in this embodiment, the projection 83d catching pressure section 83 C get equipped with smoothly sloping surfaces on the sides behind in the course and d and along one after another, in terms of the installation direction of the cartridge. Further, the protrusion 40d eject section 40C provided with smoothly sloping surfaces on the sides behind on the go and ahead along one after the other, in the sense of direction of the ink cartridge is installed. Further, when installing the cartridge 7 inclined surface 40E eject section 40C comes into contact with the inclined surface e catching pressure section 83 C get, and when the cartridge 7 is extracted, the inclined surface 40f eject section 40C comes into contact with the inclined surface 83f catching pressure section 83 C get. Moving the clamping element 83 in the direction indicated by an X on the arrow begins at the above conditions. In other words, holding the cartridge mechanism in this embodiment has such a construction that the inclined surface of the cartridge 7 remains in contact with the inclined surfaces of the primary host 100A, when the clamping element 83 is moved. Therefore, the cartridge 7 moves smoothly in the primary site, when this cartridge is installed, and gradually emerges from the primary node when the cartridge 7 is removed.

(b) Fitting the rear end of: the Operation of clamping the cartridge mechanism during installation and removal of the print cartridge

Figure 10 presents a view in plan of the left side (when viewed from re the it side) front clamping the cartridge mechanism of the primary node. Figure 11 presents a view in plan of the front side of the front (located on the rear side (in the sense of direction of the ink cartridge is installed) end) clamping the cartridge mechanism of the primary node.

When the cartridge 7 is inserted, the inclined surface 50 ppm eject section 50C supports 50, that is, the front support of the cartridge 7, comes into contact with the inclined surface e catching cartridge area 93s (stand by position)as shown in figure 10(a) and 11(a). Then, when the cartridge 7 is inserted further, the holding element 93 is gradually pushed downward, causing the projection 50d eject section 50C to come into contact with the tab 93d catching cartridge area 93s, as shown in figure 10(b). Therefore, the holding element 93 is discharged in the direction indicated by the label Y in the form of arrows (designated position). More specifically, the holding element 93 is moved to its allotted position in which it presses the section 93b is not in contact with the arresting pressure section 50b of the cartridge 7, as shown in figure 11(b). Therefore, when the cartridge 7 is set, detecting the pressure section 50b is not exposed to any pressure.

The pressure, which perceives the cartridge 7 from the holding element 93, when it is installed, removed eject section 50C, which is located farther from the axis of the second line of holes 93A, than catching directed upward force of section 50b. That is, the amount of force required to push down pull up item 93, with the resisting force which is pushing the cartridge 7 upwards, is reduced by an amount equivalent to the ratio of the distance from the centerline of the hole 93A to catching directed upward force of section 50b (who exert pulling upward force section 93b) and the distance from the centerline of the hole 93A to eject section 50C (pull up item 93). Therefore, the magnitude of the load, the impact of which is subjected to the cartridge 7, when it is installed, is substantially less than the pressure which the cartridge 7 perceives from the pull-down element 93; the amount of force that is necessary for installation of the cartridge 7, is substantially less than the amount of power that the cartridge sees from the pull-down element 93.

Further, when the cartridge 7 is set, the cartridge 7 is subjected to directed upward forces reaction forces generated when pulling up the element 93 is pushed down in its allotted position. However, the contact surface 50h comes into contact with the regulating movement of the cartridge section 96, that is in contact with the cartridge, the second section of the base node. Therefore, prevents the I movement of the cartridge 7 upwards. At the same time control the movement of the cartridge section 96 of the primary node and in contact with the main site surface 50h be located so that they remain in contact with each other until immediately preceding the correct positioning of the positioning section 50A of the cartridge due to coming in contact with catching the cartridge section 92A. Therefore, when installing the cartridge 7, more specifically, when the cartridge 7 is beginning to perceive directed upward pressure from the pull-down element 93, until the moment immediately preceding the correct positioning of the cartridge 7, and regulating the movement of the cartridge section 96, that is, regulating the cartridge section of the main site, which is made of polymer, and contacting the surface 50h cartridge slide over each other, and therefore, the positioning section 50A cartridge does not RUB about catching the cartridge section 92A of the primary node, which is made of thin sheet steel or similar material. Therefore, prevents the problem lies in the fact that the positioning section 50A of the cartridge is exposed blade scraping the impact absorbing cartridge section 92A.

When the cartridge 7 is inserted further, catching the cartridge area 93s disengages from the pushing section 50 is, and so pulling up the element 93 is gradually returned from the designated position in its position clamp. Then, when the cartridge 7 is inserted far enough so that the contact surface 50i, which is necessary for the correct positioning of the cartridge 7 in terms of the longitudinal direction of the cartridge 7, could come into contact with the side panel 82, that is, the rear side panel of the primary node, pulling up a section 93b comes into contact with the receiving pressure area 50b, as shown in figure 10(C) and 11(C), causing the cartridge 7 to Nestle (the position of the clamp in the direction marked By the arrow (drawn upward direction figure 11). During this process, the positioning section 50A cartridge available in the cartridge 7, hits in catching the cartridge section 92A of the front side panel 92 of the primary node, which leads to the correct positioning of the cartridge 7 in terms of the direction perpendicular to the mounting direction of the cartridge. Also during this process, regulating the movement of the cartridge section 96 of the primary node disengages from contact surface 50h; between regulating the movement of the cartridge section 96 and the surface 50g (recessed surface) creates a gap defined value. At the same time, catching the cartridge area 93s, perimede the Xia, bypassing the ejector section 50C; between catching the cartridge section 83 C get and recessed surface 50j creates a gap specified value.

As described above, clamping the cartridge mechanism is so designed that push up the element 93 is able to move to the standby position, pulling up position (down) and retracted position. More specifically, in the sense of the direction from top to bottom, the stand by position, is drawn upward position (down) and the designated position are in the order listed. Therefore, the holding element 93 applies a pressure of sufficient magnitude to pull up the cartridge 7.

Removing the cartridge 7 from the primary node 100A, the above-described operation of the cartridge is carried out in reverse order. Aimed upward force which the cartridge 7 perceives from the pull-down element 93 is removed with the push section 50C, which is located farther from the centerline of the hole 93A (the axis of rotation of the pull element 93)than catching directed upward force of section 50b, when this happens during installation of the cartridge 7. Therefore, the force necessary for removal of the cartridge 7 in this embodiment, is substantially less than the force required for removal of the cartridge 7 in accordance with the laws the AI with the prior art, since the amount of force required for installation of the cartridge 7 in this embodiment, is substantially less than the force required to install the print cartridge in accordance with the prior art.

However, regardless of installing the cartridge 7 in the primary site 100A or remove the cartridge 7 from the primary host 100A, it is necessary to move the pull up element 93 in the direction perpendicular to the mounting direction of the cartridge. However, in this embodiment, the protrusion 93d detecting the pressure plot 93s provided with smoothly sloping surfaces on the sides behind on the go and ahead along one after another in the sense of direction of the ink cartridge is installed. Further, the projection 50d eject section 50C is supplied smoothly sloping surfaces on the sides behind on the go and ahead along one after another in the sense of direction of the ink cartridge is installed. Further, when installing the cartridge 7 inclined surface 50 ppm eject section 50 comes into contact with the inclined surface e detecting the pressure plot 93s, and when the cartridge 7 is extracted, the inclined surface 50f eject section 50 comes into contact with the inclined surface 93f detecting the pressure plot 93s. It is in these conditions starts moving push up ale the NTA 93 in the direction marked Y in the form of arrows. In other words, holding the cartridge mechanism in this embodiment has such a construction that the inclined surface of the cartridge 7 remains in contact with the inclined surfaces of the primary host 100A, when pulling up the element 93 is moved. Therefore, the cartridge 7 moves smoothly in the primary site, when this cartridge is installed, and gradually emerges from the primary node when the cartridge 7 is removed.

Moreover, when the cartridge 7 install or remove, work clamping the cartridge mechanism occurs at the front and rear (in the sense of direction of the ink cartridge is installed) ends approximately at the same time. Further, the direction in which the turns of clamping element 83, that is, the rear clamping element is opposite to the direction in which rotates the holding element 93 (pulling up the item), that is, the front clamping element.

In more detail, as shown in Fig(a) and 12(b), on the side of the front end in terms of the direction perpendicular to the mounting direction of the cartridge, the axial line of the hole 83A is located on the left side of line L, which coincides with the axial line of the photosensitive drum 1 and is held in a direction parallel to the direction in which the cartridge 7 is moved to position ecoprofile, and detecting the pressure plot 83 C get is on the right side of the line L. on the other hand, on the side of the rear end in terms of the direction perpendicular to the mounting direction of the cartridge, the axial line of the hole 93A is on the right side of the line L, and detecting the pressure plot 93s is on the left side of line L; the positional relationship between the hole and catching pressure area on the side of the front end of the opposite positional relationship between the hole and land on the back enters the end.

That is, the holding element 83, which is located on the rear side of the primary node, is rotated in the direction indicated by a marking M in the form of an arrow, when it is moved to a given position, and a pull up element 93, which is located on the front side of the primary node, is rotated in the direction indicated by the label N in the form of an arrow, when it is moved to a designated position. Therefore, the load from the clamping elements 83 and 93 on both the front and rear sides of the primary node, the effects of which are exposed to eject the areas 40s and 50s, when the cartridge 6 install or remove, and act in the directions indicated by the marks P1 and P2 in the form of arrows, respectively Fig(a) and 12(C). The angles of the directions P1 and P2 of these loads not only the us relative to the line L, which runs in the direction in which the ejected cartridge. In addition, the above-mentioned angles are approximately symmetrical with respect to the line L, which passes in a direction parallel to the directions P1 and P2 of the load, i.e. in the direction in which the cartridge 7 is pushed upward, as shown in Fig(C). Therefore, when the cartridge 7 install or remove, it remains stable in height, having in this regard, much greater ease of use than the cartridge in accordance with the prior art.

Constructive arrangement to prevent blade scraping effects available in the cartridge positioning section of the cartridge

In this embodiment, the cartridge 7 is prevented blade scraping effect on the available positioning section of the cartridge when it is installed in the primary site 100A or removed from this node. This option may not eliminate the problem, namely, that when the cartridge 7 is set in the primary site 100A, positioning the first and second sections 40A and 50A cartridge available in the cartridge 7, RUB against the corresponding parts (elements) of the primary node 100A. Further, this option may not eliminate the problem, namely, that when the cartridge 7 is set in the primary site 100A, enter the mentioned positioning of the first and second sections 40A and 50A cartridge is introduced into contact with the corresponding parts (elements) of the primary node 100A.

That is, as described above, the supports 40 and 50, that is, relying on the sides of the front and rear ends in the sense of the installation direction of the toner cartridge provided with contacting sections 40h and 50h, which protrude upward beyond the positioning sections 40A and 50A cartridge, which plots their peripheral surfaces. These contact areas 40h and 50h are flat across the top surface and disposed on one side available in the cartridge 7 of the positioning section of the cartridge and the other side, respectively.

When the cartridge 7 is inserted into the primary site 100A having the above construction, the cartridge 7 is subjected to a downward force, that is, the reaction force generated when the holding element 83, that is, the rear clamping the cartridge element, and a pull up element 93, that is, the front clamping the cartridge element is popped down in their allotted position. During this process the contact area (contact surface) 40h comes into contact with the regulating movement of the cartridge section 86, that is in contact with the cartridge, the first section of the base node, and the contact area (contact surface) 50h comes into contact with the regulating movement of the cartridge section 96, that is in contact with the second cartridge section VI the th node. Therefore, prevents the movement of the cartridge 7 upwards.

While holding the cartridge mechanism has such a structure that regulates the movement of the cartridge section 86, that is, regulating the movement of the cartridge of the first section of the primary node, which is located on the rear side of the primary node, and the contact area (contact surface) 40h remain in contact with each other until immediately before the correct positioning of the positioning section 40A of the cartridge due to coming in contact with catching the cartridge area a. Similarly, regulating the movement of the cartridge section 96, that is in contact with the cartridge, the second section of the main site, which is located on the front side of the main node, and the contact area (contact surface) 50h remain in contact with each other until immediately before the correct positioning of the positioning section 50A of the cartridge due to coming in contact with catching the cartridge section 92A.

Therefore, when the cartridge 7 is set, and, more specifically, when the cartridge 7 is beginning to perceive aimed upward force from the clamping element 83 and the pull up element 93, until immediately before the correct positioning of the cartridge 7, the regulatory changes the group of the cartridge sections 86 and 96, that is in contact with the cartridge first and second primary node, which is made of polymer, and the positioning sections 40A and 50A cartridge, which are on both the front and rear sides, not RUB about catching cartridge parts a and 92A of the primary node, which is made of thin sheet steel or similar material. Therefore, prevents the problem lies in the fact that the positioning sections 40A cartridge exposed blade scraping the impact absorbing cartridge plots a and 92A.

As described above, the design of the clamping cartridge of the mechanism is such that installing or removing the cartridge 7 is in the exception clamping the cartridge forces due to pressure applied at the point of clamping element, which is located further from the site of clamping element, whereby the clamping element presses the cartridge 7. Therefore, the amount of force required to insert or remove the cartridge 7, is considerably smaller than the magnitude of the force (pressure)that perceives the cartridge 7 from the clamping element. Thus, the amount of force required to install the cartridge 7, that is, the cartridge in this embodiment, the main unit of the image formation in this embodiment, or d is I extract the cartridge 7 from the main unit of the image formation in this embodiment, substantially less than required for installation of the cartridge in accordance with the prior art in the main unit of the image formation in accordance with the prior art or unload a tape cartridge in accordance with the prior art from the primary node device forming an image in accordance with the prior art. In other words, the present invention can provide a cartridge and device for the formation of images, which have much better performance in the sense of the ink cartridge is installed.

In addition, when installing the cartridge 7 in the primary site 100A or removal of the cartridge 7 from the primary host 100A is prevented blade scraping effect on the positioning elements of the cartridge. Therefore, it is guaranteed that the cartridge 7 is positioned correctly.

While the design of image formation in this embodiment is such that the cartridges are arranged side by side (in parallel) in a horizontal straight row, and on the upper side of the cartridge is located intermediate transfer so that the cartridges can be pressed from the bottom upwards by means of clamping elements. However, this type of implementation should not be considered as limiting the present invention in terms of device design of creation the image. For example, the present invention is applicable also to the design of image formation, the construction of which is such that this block of intermediate transfer is on the bottom of the cartridges, and the cartridges are pushed from the bottom upwards by means of clamping element (clamping area). In the case of this structural arrangement, the photosensitive drum 1 is put into contact with the intermediate transfer ribbon 5 by application of directed downward pressure to the cartridge 7.

In the case of a device forming an image such as a device in this embodiment having such a construction that the cartridges are pressed from below, the amount of force required to compress the cartridge for correct positioning of the cartridge should be set taking into account the weight of the cartridge. So it must be greater than the force required to compress the cartridge in the unit of image formation, the construction of which is such that the cartridge is pressed from above, and the amount of force required to eject the cartridge down. Thus, the effects of the present invention will be strengthened by designing the device forming the image so that the cartridge can be inserted or removed, excluding the application of pressure to the cartridge holding is artridge plot clamping the cartridge element, i.e. plot clamping the cartridge element, which is located farther from the axis of rotation of the clamping cartridge element than clamping the cartridge section presses the cartridge element.

In this embodiment, also provides that on both sides - front and back ends (in the sense of direction of the ink cartridge is installed) - force applied from the clamping cartridge element (including pulling up the item) excluded by section presses the cartridge element, which is located farther from the axis of rotation of the clamping element than clamping the cartridge plot cartridge element when installing or removing the cartridge. However, you should not consider this option implementation limit the claims of the present invention in the sense of the structure of the device forming the image. For example, device imaging can be designed so that only one end of the device forming the image, that is, either the front or rear end in the sense of the installation direction of the toner cartridge provided with clamping cartridge element. However, device imaging, with the presser element and on the front end and rear end in the sense of the direction of installation of the cartridge, is characterized less by the amount of force required for the stop or remove cartridge, than the device forming images having a clamping element only on the front end or the rear end in the sense of direction of the ink cartridge is installed. In addition, as described above, by constructing the device forming the image so that the clamping cartridge element on the rear side and presses the cartridge element on the front side symmetric with respect to the direction in which has a pushing effect of the strain of the clamping element, it becomes possible to maintain the cartridge 7 stable height when installing or removing the cartridge 7, further enhancing the effects of this variant implementation of the present invention.

Option 2

Next, with reference to Fig and 14, will be described a second variant implementation of the present invention. Moreover, this alternative implementation for the basic design of the device forming the image is the same as the first version of the implementation described above. Therefore, to avoid repeating the same descriptions, the description of this option will be limited to the constructive characteristics that differ from those present in the first embodiment. In addition, elements, parts, etc., device, image formation in this embodiment, the cat is who on the functioning of the same with those which are present in the first embodiment denoted by the same theme items.

On Fig presents promising external image cartridge in this embodiment. On Fig presents a schematic perspective representation of the positioning of the cartridge element and clamping the cartridge element on the rear side of the main unit of the image formation, illustrating their design.

The device forming the image in the first embodiment, was so designed that the bearing cartridge 7, which is located on the front end in the sense of the direction in which the cartridge 7 is set in the main unit of the image formation, provided with a clamping element 83 having an ejecting section 83 C get to eject the cartridge 7 down. In this embodiment, will be described the processing unit image which has such a design that pushes the plot is part of the processor unit.

As shown in Fig it developing unit 4 is equipped with push clamping element section 140 C, which is designed to move the clamping element in its allotted position. Eject section 140 C is ahead on the fly" - in the sense of the direction of installation of the cartridge is located "in front of the direction of the" end of ka is drier cartridge 7. The tail part of the eject section 140 C is equipped with a protrusion 140d, which acts downwards. The ledge 140d has two surfaces a and 140f, which gradually tilted in such a way that their intersection is a vertex of the protrusion 140d. In terms of the direction perpendicular to the mounting direction of the cartridge eject section 140 C is on the opposite side of the arresting pressure section 40b from the centerline of the hole 183a (Fig) clamping the cartridge element 183 (who exert pressure element, which will be described later. In addition, the pushing section 140 C is farther from the centerline of the hole 183a than catching pressure section 40b.

As shown in Fig, the primary host 100A is equipped with clamping cartridge element 183, which is designed to clamp the cartridge 7 for detecting the cartridge section a (catching pressure area). Clamping element 183 is under catching cartridge plot a. Clamping element 183 is attached to the side panel 82, i.e. the side panel of the main body on the rear side; the axis 84, rigidly attached to the side panel 82, is inserted through hole 183a clamping element 183 in such a way that the axis of rotation of the clamping element 183 coincides with the axial line of the hole 183a. In addition, the holding element 183 is attached with chief is to the side panel 82 so he has the ability rotary movement in the position of the clamping cartridge, in which he presses the cartridge 7 for detecting the cartridge section a, and the position of the outlet, in which his move to relieve the pressure that it applies to the cartridge 7.

Further, the holding element 183 is equipped with clamping section 183b, which presses the cartridge when the clamping element 183 is in the position of the clamp. Clamping section 183b position corresponds to detecting the pressure section 40b of the cartridge 7. Clamping element 183 is also provided with a safety pressure plot C, which is designed to move the clamping element 183 in the designated position. Catching pressure plot s corresponds to the position of the eject section 140 C of the cartridge 7.

Catching pressure plot is equipped directed upward protrusion 183d, which has two surfaces a and 183f. These surfaces e and 183f are on the sides behind on the go and ahead on a course in the sense of the installation direction of the toner cartridge, and gently tilted so that their intersection is a vertex of the protrusion 183d.

In terms of the direction perpendicular to the mounting direction of the cartridge detecting the pressure plot C is on the opposite side of the clamping section 183b from the centerline hole at back the Oia 183a. In addition, detecting the pressure plot C is farther from the centerline of the hole 183a than holding section 183b.

Next will be described the moving components of clamping cartridge mechanism in this embodiment, that is, when the cartridge 7 is set in the device 100 of image formation. On Fig presents a view in plan of the rear clamping the cartridge mechanism (when viewed from the front side of the device forming the image) of the main unit of the image formation, illustrating the operation of clamping the cartridge element, which occurs when the cartridge 7 is set in the primary site 100A. On Fig presents a view in plan of the rear clamping the cartridge mechanism, when viewed from the incident side in the installation direction of the cartridge) end of the cartridge 7, illustrating the operation of clamping the cartridge element.

The cartridge 7 is set in the direction indicated by the label F in the form of arrows on Fig(a). As shown in Fig(a) and 17(a), when the cartridge 7 is inserted, the inclined surface e eject section 140 C developing unit 4 comes into contact with the inclined surface e catching cartridge area s (stand by position). Then, when the cartridge 7 is inserted further, the holding element 183 is gradually pushed downward, the SaaS is avlee ledge 140d eject section 140 C to come into contact with the tab 183d catching cartridge element s, as shown in Fig(b). Therefore, the holding element 183 is discharged in the direction indicated by the label T arrow (designated position). More specifically, the holding element 183 is given in its allotted position in which it presses the section 183b is not in contact with the arresting pressure section 140b of the cartridge 7, as shown in Fig(b). Therefore, when the cartridge 7 is set, detecting the pressure section 140b is not exposed to any pressure. The pressure, which perceives the cartridge 7 from the clamping element 183, when it is installed, removed eject section 140 C, which is located farther from the axis of rotation of the clamping element 183, which coincides with the axial line of the hole 183a. That is, the amount of force required to push down the clamping element 183, providing resistance to the force which is pushing the cartridge 7 up, reduced depending on the ratio of the distance from the centerline of the hole 183a catching up pressure section 140b (eject section 183b) and the distance from the centerline of the hole 183a to eject section 140 C (catching pressure plot C). Therefore, the magnitude of the load, the impact of which is subjected to the cartridge 7, when it is installed, is substantially less than the pressure that CT is the ridge 7 perceives from the clamping element 183; the amount of force that is necessary for installation of the cartridge 7, is substantially less than the pressure required for installation of the cartridge 7 in accordance with the prior art.

Further, when the cartridge 7 is set, the cartridge 7 is subjected to directed upward forces reaction forces generated when the clamping element 183 is pushed down in its allotted position. However, the contact surface 40h comes into contact with the regulating movement of the cartridge section 86, that is in contact with the cartridge, the first section of the main site. Therefore, prevents the movement of the cartridge 7 upwards. At the same time control the movement of the cartridge section 86 of the primary node and in contact with the main site section 40h of the cartridge 7 are arranged so that they remain in contact with each other until immediately preceding the correct positioning of the positioning section 40 of the cartridge due to coming in contact with catching the cartridge area a. Therefore, when installing the cartridge 7, more specifically, when the cartridge 7 is beginning to perceive directed upward pressure from the clamping element 183, until the moment immediately preceding the correct positioning of the cartridge 7, and regulating the movement of the cartridge the plot 86, that is, regulating the cartridge section of the main site, which is made of polymer, and contacting the surface 40h slide over each other, and detecting the pressure section 40A (available in cartridge positioning section of the cartridge) does not RUB about catching the cartridge area a the primary node, which is made of thin sheet steel or similar material. Therefore, prevents the problem lies in the fact that the positioning section 40A of the cartridge is exposed blade scraping the impact absorbing cartridge area a.

When the cartridge 7 is inserted further, catching the cartridge area C disengages from the pushing section 140 C, and therefore the clamping element 183 is gradually returned from the designated position of the clamp. Then, when the cartridge 7 is inserted far enough so that the contact surface 40i, which is necessary for the correct positioning of the cartridge 7 in terms of the longitudinal direction of the cartridge 7, could come into contact with the side panel 82, that is, the rear side panel of the primary node, the holding section 183b comes into contact with the receiving pressure area 40b, as shown in Fig(C) and 17(C), causing the cartridge 7 to Nestle (the position of the clamp in the direction indicated by the label's arrow (direction down). Those who tell of this process, positioning section 40A cartridge available in the cartridge 7, hits in catching the cartridge area a rear side panel 82 of the primary node, which leads to the correct positioning of the cartridge 7 in terms of the direction perpendicular to the mounting direction of the cartridge. Also during this process, regulating the movement of the cartridge section 86 of the primary node disengages from contact surface 40h; between regulating the movement of the cartridge section 86 and the surface 40g (recessed surface) creates a gap defined value. At the same time, catching the cartridge area s moves past the eject section 140 C; between catching the cartridge area s and recessed surface 140j creates a gap specified value.

In this embodiment, also guaranteed the application pressure of sufficient magnitude clamping element 183 to the cartridge 7.

Removing the cartridge 7 from the primary node 100A, the above-described operation of the cartridge is carried out in reverse order. Aimed upward force which the cartridge 7 perceives from the clamping element 183 is excluded eject section 140 C, which is located farther from the centerline of the hole 183a, as during installation of the cartridge 7. Therefore, the magnitude of the force required to extract install the ja 7 in this embodiment is significantly less than the force required for the operation of the extraction cartridge in accordance with the prior art, since the amount of force required for installation of the cartridge 7, is significantly less than the force required for the operation of the ink cartridge is installed in accordance with the prior art.

Further, when detecting the cartridge area a primary node disengages from catching pressure section 40A (positioning section of the cartridge, available in cartridge) governing the movement of the cartridge section 86 of the primary node comes into contact with the second contact surface 40h. In addition, even during extraction of the cartridge 7, which regulates the movement of the cartridge section 86 of the primary node, which is made of polymer, and the second contact surface 40h cartridge slide over each other, thereby preventing the friction of the positioning section 40A cartridge safety cartridge plot a sidebar of the main site, as the cartridge 7 is under directed upward forces applied clamping element 183. Therefore, prevents the problem lies in the fact that the positioning section 40A cartridge positioning section of the cartridge, available in cartridge) exposed blade scraping the impact of catching the cartridge from Asda a, when rubs about this catching cartridge plot a.

In this embodiment, only the area processing unit 4, which position corresponds to the side of the rear end of the main unit of the image formation, equipped with a buoyancy section. However, the buoyancy of the parcel may be provided with only the front end processing block.

The effects of supply only the front end of the processor unit eject the plot are the same as those achieved by supplying only the rear end of the developing unit eject section.
