Background of invention

The technical field

The present invention relates to the management of feeding the media printed information. In particular the present invention relates to structures used to define the initial position or phase of the pickup roller during its rotation, and the method of such determination in design, intended to feed the media the printed information using the pickup roller.

The level of technology

In recent years, the printing devices has increased the volume of printing photographic images not only on plain paper but also on paper for special purposes. In particular, in devices inkjet printing continues the process of reducing the size of ink droplets, and it became possible to print an image whose quality is comparable or exceeds the quality of the photos based on silver salts having a high resolution. Simultaneously with the implementation of such high-resolution images also increases the accuracy of paper feed, and offers a number of ways, based on the use of the pickup roller, a metal shaft which is covered with abrasive material, as well as ways to control the movement of such pickup roller with high precision.

For example, in Japanese laid patent application No. 2006-240055 describes the design, in which on the same axis as the feed roller set encoding disk, and barcode labels made on its circumference with the same interval, detect by means installed in the device code of the sensor. Thus, the described technology control the operation of the direct current motor designed to rotate the feed roller in accordance with the detection cycle barcode labels, etc. in Addition, according to the mentioned document proposes a method of obtaining the initial position of the pickup roller by creating a drawing to determine the phase rotation separately from the barcode labels on the encoding disc and detection of this pattern using a different sensor for the correction of errors in pitch, due to the eccentricity of the conveying roller.

Fig is a view in section, illustrating the location of the encoder disc and sensor. Encoding disk 2002 in the form of thin plates has the same axis of rotation, and the pickup roller 2001, and installed in such a manner that goes around the entire circumference of the roller 2001. For encoding a disk printed barcode labels 2002a, performed at regular intervals and used to determine the positioning accuracy, and figure 2002b in the form of a tape, is used to determine the phase of rotation of the roller. The encoder 2003 installations is N. in that place, where during the rotation of the encoder disk 2002 are dashed label 2002a, and determines the amount of rotation of the encoder disk 2002, i.e. the pickup roller 2001. On the other hand, the sensor 2004 region detects the edge of the picture 2002b, which moves along with rotation of the encoder disk 2002, and the printing device is configured to set the initial position during the rotation of the roller due to the use of this detected point in time.

Fig is a drawing illustrating another example of the structure used to define the initial position of the pickup roller. In this example, the detectable portion 2101 is attached to the parcel pickup roller 2101 and moves, describing a circle, together with the rotation of the pickup roller 2101. The photo interrupter 2103 installed in the device, where the detectable portion 2102, and can determine the initial position of the pickup roller 2101 based on the time when the detectable portion 2102 is shielded by photo interrupter 2103.

Thus, to control the flow with high accuracy while correcting an error of the feed resulting from the eccentricity of the conveying roller, in addition to the mechanism for determining the amount of rotation of the pickup roller also need a mechanism to determine the initial position of the roller.

The invention

The present invention is created to solve these problems, and its objective is to offer a printing device capable of determining the initial position of the pickup roller with the use of relatively simple design, and moreover such that it is not accompanied by an increase in value.

The first aspect of the present invention is a printing device for printing an image on a medium printed information using the print head, which contains the drive unit, is arranged to actuate the pickup roller serving to feed printed media data; node calculation performed by the calculation of the amount of rotation of the pickup roller; node lock configured to lock rotation of the pickup roller in a predetermined position of rotation; and a node definition that uses the calculated value received from node calculation, when the pickup roller is blocked by node lock, as reference values, and determines the phase rotation the pickup roller on the basis of reference values and the calculated values received from the node is asceta.

The second aspect of the present invention is a method for determining the initial position of the pickup roller serving for supplying medium of printed information in the printing device, designed for printing on media of printed information using the print head, which contains the following stages: stage move the start node, configured to lock the pickup roller, in the locked position; the step of bringing into rotation of the pickup roller; a step of calculating the magnitude of the rotation of the pickup roller from the beginning of rotation of the roller at the stage of bringing into rotation until the time when this video is blocked; and a step of saving the calculated values obtained at the calculation step.

Description of variants of realization of the invention

Next, with reference to the drawings will be described preferred embodiments of the present invention in practice.

The first option

Figure 1 is a General view of the mechanical assemblies of the printing device in this embodiment implementing the present invention.

(A) the Site feed

Site submission is of such a construction, by which the base 20 of the delivery unit installed pressure plate 21 on which load the printed media, the loading roller 28, used for uploading media P printed information on one sheet separating roller, designed to separate novtel the th printed information (not shown), return the lever that is designed to return the medium of printed information in the loading position (not shown), etc. pressure plate 21 provided with a movable side guide 21, which is made with the ability to move and adjust the position of the load carrier of printed information. The pressure plate 21 is made to rotate around an axis, which is connected with the base 20 of the delivery unit, and push in the direction of the loading roller 28 by means of a spring presser plate which is not shown. The loading roller 28 is made in the form of a roller having a cross-sectional view of an arc of a circle, and loads the media printed information inside the device due to its rotation while maintaining contact with the surface of the carrier printed information. The printed media abuts the gripping region formed of the loading roller 28 and the separating roller, and are separated by means of this gripping region; and only the printed media information held in the upper position, served on inside. On the loading roller 28 by the motor 99 load torque acts, which is created by transferring the driving force of the motor 99 download, which is a tool for downloading through the drive sprocket, the slave tooth is the ATA wheel etc. The driving force of the motor 99 download is also passed to the purification unit, which will be described later.

(C) Site submission

The main elements of the delivery unit mounted on the frame 11 in the form of a metal plate which is bent and towers, as well as on the frames 97, 98, manufactured by casting in the form. The printed media in the information sent to the site feed is sent via paper guide and holder pressure roller 30, which have a specific location in the intake hole and held between a pair of rollers consisting of the conveying roller 36 and the pressure roller 37. The pickup roller 36 is made in the form of a metallic shaft having a coating of fine particles of ceramics, and lots of metal on both ends of this shaft are based on bearing elements attached to the frame 11. The holder 30 pressure rollers serves as a support for a multitude of clamping rollers 37, each of which is pressed against the surface of the pickup roller 36 under the action of the spring 31 and the pressure roller, and each pressure roller 37 is adjacent to the surface of the pickup roller 36 and is driven.

2 and 3 are respectively a view in section, and General appearance, used for detailed explanations of the feeding mechanism, comprising a delivery unit in the printing device corresponding to this implementation variant n the present invention. Torque of the pickup roller 36 occurs as a result of the process by which the driving force of the motor 35 feed, representing a direct current motor, is transmitted to the transmission 361 with a pulley mounted on the same axis with the feed roller 36, through the synchronous belt 39. On the same axis as the feed roller 36, set encoding disk 362, which made the bar label increments from 150 to 360 lines per inch (lpi lines per inch) and which is directly connected with the roller 36. In addition, the frame 11 shown in the drawing, is mounted encoder sensor 363 pickup roller, designed to determine the number of passages of the bar labels, encoding is performed on the disk 362, and the corresponding moments of time.

As also shown in figure 1, when the pair of rollers consisting of the conveying roller 36 and the pressure roller 37, is driven into rotation by an electric motor 35 feed printed media information held by the pair of rollers, is fed into the device. The holder 30 pressure rollers are equipped with edge sensor designed for detecting front and rear edges of the printed media information and for its positioning. By detection using sensor edge media printed information is positioned on buyhoodia platen 34, which is mounted on the frame 11 and is in the Le is printed.

(C) the Node carriage

On the media printed information, a support to which the lower side is bumagoopornogo roller 34 located below the feed roller 36 in the direction of flow, on the basis of information for prints an image using a print head 7 mounted on the carriage 50, which moves from the top side of the media printed information.

The carriage 50 is used to install the print head 7 and the tank 71 with paint for paint flow in said head, and arranged to move in the X direction shown in the drawing. The print head 7, the corresponding implementation variant of the present invention, is so designed that the voltage pulse could affect the heater installed in the position corresponding to separate the outlet, and the paint could be produced from a single outlet using the pressure changes that occur during the growth or contraction of the air bubble created in film boiling. However, the present invention is not limited to this way of release.

Support the carriage 50 serves as a guide rail 52 of the carriage, acting in directions perpendicular to the feed direction of media printed information, as well as the upper guide rail 111, which, in this clicks the zoom, guide the carriage in accordance with the direction of its movement. Guide rail 52 of the carriage attached to the frame 11 and the upper guide rail 111 is made with the frame 11 as a whole. In addition, the upper guide rail 111 holds the end of the carriage 50, and also performs the function of maintaining the gap between the plane of the outlet of the print head 7 and the carrier of printed information.

The carriage 50 is moved under the action of the driving force of the motor 54 attached to the frame 11, which is transmitted to the carriage through a tension pulley 542 and synchronous belt 541, which is installed on the tensioner pulley 542 taut and supported by the pulley. In parallel, synchronous belt 541 taut cord set tape 561, which made the label increments from 150 to 300 lines per inch, and these labels during displacement of the carriage 50 find not shown encoder sensor mounted on the carriage. Thus, it is possible to determine the current position of the carriage 50. Flexible cable 57 provides the electrical connection available on the carriage 50 Board on which are placed the encoder etc., installed in the electric device - 91, while following the reciprocating movement of the carriage 50. The signal of printing in which the print head 7 performs printing, the forehand is raised it from the wiring Board 91 by a flexible cable 57 and through the cost of carriage. In accordance with the print signal during the movement are driven by separate heaters of the print head 7, and the media printed on buyhoodia platen 34, the printing point.

(D) the discharge unit

Torque discharging roller 40 occurs as a result of the process by which a torque of the pickup roller 36 is transmitted to the toothed wheel 404 discharging roller, which is directly connected with the roller 40, the toothed transmission parts 361 with a pulley directly connected to the feed roller 36, through an intermediate gear wheel 45. As also shown in figure 2, on the same axis with the discharging roller 40 is selected encoding disk 402 discharge, and the amount of rotation of the discharging roller 40 is determined using the encoder 403 discharging roller.

On the holder 43 has lots of short protruding plates, and these short protruding plate is pressed to the discharging roller 40 by means of springs, each of which is a helical spring having a cylindrical shape. Submission of printed media information, on which the print head 7 created the image that occurs while holding the media between the discharging roller 40 and many of these short tips of the protruding plates, and printed media and the formation unloaded.

(E) Site cleanup

Node 60 cleaning consists of a pump to clean the print head 7, a cap to prevent drying of the print head 7, a blade for cleaning the plane of the outlet openings in the printhead 7, etc. the Main driving force of the purification unit is created due to the transfer of power from the motor 99 boot that has already been considered. Node 60 performs cleaning operation suction unnecessary paint, etc. from the print head 7 by the switch on the pump when installed on the print head 7 cover, the operation of cleaning the working surface of the print head 7 through the moving blades and the like.

Below will be considered a constructive solution for this variant implementation of the present invention.

4 and 5 are drawings used to explain the mechanism for determining the initial position of the pickup roller 36, corresponding to this implementation variant of the present invention, where figure 4 shows the transmission 361 with a pulley located on a feed roller 36, if you look at it from the front side, and figure 5 shows the same as viewed from the rear side. On the transfer 361 with a pulley installed the lock ring 4001, having a round section a and a concave section 4001b, which rotates as a unit with the feed roller 36. When turning around C is NTRA a stopping lever 4002 can stop the lock ring 4001, abutting the locking part 4002b in the concave section 4001b this ring 4001. The rocker lever 4003 lock is a lever that is designed to compress and discharge of the stopping lever 4002, and the pressing force and the force of the discharge occurring between the rocker lever 4003 blocking and stopping lever 4002, are created by means of a spring 4004 stopping lever. Power Ftg to rotate the rocker lever 4003 block is created by carriage 50 moving in the lock position, which is opposite the position of rest and out of scan range when printing (the left edge in figure 1).

6 is a drawing showing the state of the carriage 50 in the printing device corresponding to this implementation variant of the present invention, if you look at this slide from the back side, i.e. in the opposite direction compared to Fig 1. On the reverse side of the carriage 50 has a protruding portion 50A. When the carriage 50 is moved to the lock position, the protruding portion 50A comes into contact with the beveled part a rocker lever 4003 lock. If this contact to the beveled portion a rocker lever 4003 lock is applied additional force Fcr-specified value, as also shown in Figure 4 or Figure 5, it will experience a force Ftg, which causes the rocker R is the CAG 4003 lock to turn in the direction indicated on the drawing by an arrow.

Figa-7C are views in section, used for specific explanations of the stages, in which the lock function is carried out using the mechanism explained with reference to Figure 4-6.

Figa is a drawing illustrating the state in which the carriage 50 is not in the locked position. As the rocker lever 4003 lock is not pressed, the locking ring 4001 and stopping lever 4002 not touch each other. During printing, the feed roller 36 and the locking ring 4001 rotating in discontinuous mode is shown in the drawing direction CW to feed printed media information.

On FIGU shows the condition when the carriage 50 is moved to the lock position, and the rocker lever 4003 lock is pressed with a projecting part 50A of mechanical triggering device. The occurrence of power Ftg causes the rocker lever 4003 lock to turn, and stopping lever 4002 comes in contact with a circular plot a locking ring 4001 under the action of the spring 4004 stopping lever. While stopping lever 4002 made so that he could enter into the rocker lever 4003 block, even if this lever 4002 presses round the site a the locking ring. Therefore damage when hitting the ledge is a growing part 50A of the carriage 50 of the rocker lever 4003 lock. In addition, if the stopping lever 4002 and the rocker lever 4003 block initially created is described by as separate components, it is possible to separately adjust the stroke rocker lever 4003 block and the amplitude of swing of the lever 4003, respectively. In the result, it is possible to fix the stroke, which will not depend on the tolerance in the position of these parts at the same level at which the stopping lever 4002 will enter into the concave section 4001b locking ring.

Figs is a drawing illustrating the state where the pickup roller 36 is turned even further compared with the state shown in Figv, and the rotation is blocked by the locking ring 4001. When the locking ring 4001 further rotated in the CW direction while stopping lever 4002 is adjacent to the circular plot a locking ring 4001, blocking part of the stopping lever 4002 will be included in the concave section 4001b locking ring 4001. As a result, then the blocking portion prevents rotation of the locking ring 4001 in the CW direction. That is, the rotation of the locking ring 4001 and the pickup roller 36 is blocked. Moreover, in this case, since the lock ring 4001 is attached to the transmission with a pulley 361 intended to transfer DV the driving force from the electric motor 35 feed between the feed roller 36 and the transfer of 361 with the pulley does not occur torque.

This blocked state (stopped state) occurs only in one predetermined position of all positions when the pickup roller 36 performs one revolution. Therefore, the position where the pickup roller was blocked (stopped) in the manner described, can be considered the starting position of the pickup roller.

In addition, it is desirable that the direction of rotation of the pickup roller when defining a locked state represented the direction in which during the print media is printed information (direction CW), as discussed above. Moreover, in the locked condition, as shown in Fig, on the basis of the action of the driving force Fdrive pickup roller 36 and strength Flock reaction lock-side stop lever 4002 creates a resultant force F and occurs angular momentum Mlock lock ring 4001. In this case, to install the pickup roller 36 in the bearing to ensure the reproducibility of filing, it is desirable to place the individual elements so that the resultant force F can act in the direction of the bearing 8001, which serves as a support for the shaft of the pickup roller 36.

As described above, the locking ring 4001 also serves to prevent sock the swinging synchronous belt 39 and, as discussed above, made in the form of a cast element, separate from the transmission 361 with a pulley. However, when jumping synchronous belt it is impossible, and when the device is so designed that the feed roll is driven by means of gears, the locking ring 4001 and transfer 361 with a pulley can be a single item. Be that as it may, it is required that the elements had such a design, in which the driving force of the motor 35 of the feed and the reaction force when locking the pickup roller 36 could not cause the appearance of differences in the phase rotation between the feed roller 36 and the transfer of 361 with a pulley or between the feed roller 36 and coded disk 362, or the like. It also makes sense to set an upper limit for the control voltage and the pulse width of the electric motor 35 of the feed or to set an upper limit for the torque to prevent damage to the parts.

In this embodiment implementation of the present invention, as shown in figure 2, in a state where the rotation of the pickup roller 36 is blocked (suspended), is determined by the state, when the encoder sensor 363 pickup roller ceases to detect the barcode label on the encoding disc 362.

Figa and 9B are drawings each of which shows the points of time and, when the encoder sensor 363 pickup roller detects barcode labels encoder disk 362, pending on the horizontal axis t of time. On Figa shows the state where the pickup roller 36 is rotated at a given speed. This shows the condition when the specified time is detected seven barcode labels with Sn in Sn+6. As bar-tag encoding is performed on the disk 362 with the same interval, then the rotation of the pickup roller 36 at a constant speed encoder sensor 363 pickup roller detects barcode labels at a fixed thus the time intervals. On the other hand, figure 9 shows the state when the direction of rotation of the pickup roller 36 is blocked. Here once detected barcode labels up to Sn+3 next, detection of bar labels does not occur even after a predetermined time. At the time when this situation occurs, the control unit of the printing device may determine that the pickup roller 36 has been in a blocked state.

More specifically, when the number of barcode labels, detected within a given time, comprising, for example, approximately 200 MS, less than or equal to 10, we can assume that there is a locked state. In addition, the state can be considered the locked state, for example, when sledujuschtschaja label cannot be detected within a specified time after time, when he was diagnosed with one stroke mark. With this design in this embodiment implementation of the present invention can be guaranteed to determine the initial position of the pickup roller using an existing encoder with high resolution, without installing a new electronic device.

11 is a block diagram serving to explain the principles of managing printing device corresponding to this implementation variant of the present invention. The CPU 501 controls the mechanisms available in the device, via the controller 502 in accordance with various programs stored in the ROM 504. When this RAM 503 is used as a work area, primarily during different portions of the data, or run-time processing. The CPU 501 executes the image processing for converting the image data into the print signal, which can be printed printing device for image data received from the host device connected to the external environment. Then, the CPU 501 activates the motor 506 by means of a drive device 507 motor and actuates the print head by means of a drive device 509 for the print head to form an image on the media is ecatel information. In the drawing, the motor 506 and drive unit 507 for the motor illustrated in aggregate the electric motor 35 of the feed motor 54 of the carriage, the motor 99 load and the corresponding drive devices that were described earlier.

Electrically writable EEPROM 508 (Electrically erasable programmable read-only memory) stores the values set on the production and updating data, and these data are used by the controller 502 and the CPU 501 as control parameters. Sensor 505 illustrates the combined temperature sensors and the code sensors installed in various locations of the device, and one of them is the above-mentioned encoder sensor 363 pickup roller. The CPU 501 overwrites payroll information, which was received code sensor 363 pickup roller detection barcode labels, in a ring buffer RAM 503, if necessary. When the determined initial position, the initial position is stored in another area of RAM 503 or in EEPROM.

Fig is a block diagram serving to explain the steps of the process performed by the CPU 501 for determining the initial position of the pickup roller 36.

At the beginning of the process of determining the initial position, the CPU 501 plumage is eweet the carriage 50 in the locked position by actuation of the motor 54 of the carriage at Step S1201. In the protruding portion 50A, available on the carriage 50, rests on the beveled part a rocker lever, rocker lever 4003 lock turns, and stopping lever 4002 is adjacent to the circular plot a locking ring 4001.

In the next Step S1202, the CPU 501 rotates the pickup roller 36 in the direction of flow of the carrier printed information (direction CW 7) by actuation of the electric motor 35 of the feed. This also simultaneous detection of bar code labels sensor pickup roller. If the CPU 501 detects the locked state of the pickup roller 36 on the basis of the information of the calculation from the code sensor 363 pickup roller, the CPU 501 stops the motor 35 supply and stops the feed roller 36 (Step S1203).

At Step S1204, the CPU 501 stores in the RAM 503 or EEPROM 508 position of rotation at which the encoder sensor 363 pickup roller discovered the locked state, as the information about the start position.

After that, at Step S1205, the CPU 501 displays the carriage 50 from the position lock. In addition, at Step S1206, the CPU 501 causes the pickup roller 36 to rotate by a specified amount in the CCW direction by actuation of e is extradigital 35 feed direction, the opposite of normal. As a result of this concave section 4002b locking ring ceases to be in contact with the stop lever 4002. In the manner described above, this process is terminated.

The value received from encoder 363 pickup roller in the calculation for one rotation of the pickup roller 36, is a known fixed value, and it is used as one cycle when the phase control. As a result, when performing print operations after the above process of determining the initial position of the calculated values is always possible to know the phase of the pickup roller 36, which then determines the encoder sensor 363 pickup roller based on the information about the initial position stored in the Step S1204. That is, the CPU 501 can feed media printed with high precision, at the same time correcting the error of the feed resulting from the eccentricity of the conveying roller, using the value of the rotation and phase of the pickup roller received from the encoder 363 pickup roller.

Moreover, although the above has been considered a variant of the present invention, structurally implemented in such a way that the position at which the encoder sensor 363 pickup roller detects the locked state, maintaining the axis as information about the initial position, the calculated value is stored and updated in time, when detected that the locked state can be reset to zero. If you continue this modification, then the phase control can be performed in a state where the initial is the calculated value of zero.

Note that the phase control after the process of determining the initial position, which was described above can properly be performed during operation of the encoder 363 pickup roller. However, if there was a single "hard" power, encoder sensor 363 pickup roller stops working, and the data in RAM will be erased so the information about the initial position and the calculated values will be lost. Thus, when returning from the "hard" power off printer corresponding to this implementation variant of the present invention, will be again to obtain information about the initial position, carrying out the several stages of the process of determining the initial position, as shown in the block diagram shown in Fig.

In addition, even if the device is in continuous power, if we take into account the energy savings and the extension of the service life of the encoder may be a situation when the encoder sensor 363 pickup roller doesn't work during soft power-down or if no print. In this situation, the number of stages of the process of determining the initial position shown in the block diagram Fig may be executed every time the encoder sensor 363 pickup roller is returned in working condition. In addition, in a situation where there is the slightest fear that the pickup roller 36 is rotated under the action of external forces during idle time encoder 363 pickup roller, it also makes sense immediately before cessation of operation of this encoder 363 immediately to save the information about the phase and the start position.

In addition, there is a situation where, depending on the type of image data, media type print information, etc. can be determined that there is no need to control the phase of the pickup roller 36. In such a situation, the above-described process of determining the initial position can be performed at the time when the first time after the "soft" power for the first time performed the printing operation, which requires management phase of the pickup roller 36.

In the above embodiment, the implementation of the present invention, as shown in Figure 4 and Figure 5, the lock function is implemented in such a way that the locking ring 4001 is made concave section 4001b, and it includes the upper end of the stopping lever 4002, but the shape of the locking ring specified not exhaust anchoveta. For example, the same function may be realized by providing a protruding portion in a certain place of a circular plot of the locking ring 4001 and making this protruding portion is shaped so that the upper end of the stopping lever 4002 rested on its side surface s.

In addition, although the above has been considered a variant of the present invention, structurally implemented in such a manner to lock the rotation of the pickup roller 36 was found using information from the encoder 363 pickup roller, the present invention is of such construction is not limited. For example, in the case where the ratio of rotation of the conveying roller 36 and the discharging roller 40 is 1:1, it is also possible to determine that the pickup roller 36 is in a blocked state, using the information of the encoder 403 discharging roller. In addition, having a mechanism for locking the roller on the side of the discharging roller 40, it is also possible to detect the locked state of the discharging roller 40, using the information encoder 363 pickup roller and encoder 403 discharging roller. Similarly, as blocked (stop) of the object can be considered the gears are used to transmit the driving force, for example an intermediate gear 45, and separately it is possible to provide means defined the I magnitude of rotation of one of these gears.

As discussed earlier, in accordance with this variant of realization of the present invention can obtain the initial position of the pickup roller with high accuracy by combining in a single node of an existing encoder having high resolution, and a few pieces of cheap mechanical elements, installing a new electronic device and the wiring for it.

The second option

In this embodiment implementing the present invention will also be used printing device shown in Fig.1-5. However, in this embodiment implementing the present invention as a means of pressing rocker lever 4003 block is additionally used, the switching mechanism of the distance to the paper, pre-installed on the back side of the carriage 50. This switching mechanism of the distance to the paper is a mechanism, which is mounted on the carriage for adjusting distance between the plane of the outlet of the print head 7 and the printed media information depending on the type of the media.

Figa-13C are drawings used to explain the switching mechanism of the distance to the paper in this embodiment implementation of the present invention, when viewed on the carriage 50 with its reverse side. Figa-14C are drawings illustrating with alsasua support 1301, shown in Figa-13C, when viewed from the side of the cradle.

Sliding support 1301 represents the axial element that slides along the guide rail 52 of the carriage when moving the carriage 50. The slider 1302 switching of the distance to the paper slides shown in the drawing direction And held by the carriage 50 and the sliding pillar, causing it changes the distance between the carriage 50 and the sliding support 1301, i.e. the height of the carriage 50.

On Figa and Figa shown condition with a small distance to paper (normal position), i.e. the position used for printing on plain paper or photo paper. If the carriage 50 is moved towards And from this state, because the protruding portion a available on the slider 1302 switching of the distance to the paper, is retained by the obstacle in the direction of a moving carriage 50 and the sliding support 1301. That is, the relative positions in the horizontal direction of the slider 1302 switching distance up the paper and sliding support 1301 changes, but also changes the relative position in the direction of height due to the mutual inclination. As a result, the carriage mounted on the slider 1302 switching of the distance to the paper rises. On Figv and 14B shows the state in which the carriage 50 is raised in this way on the od of the n step, to place her in a position where the distance to the paper is large, namely to print on thick paper, etc. (position "thick paper"). In addition, if the carriage 50 is moved further in the direction And in the same way, the carriage 50 will rise by an additional one step. On Figs and 14C shows a state in which the carriage 50 is additionally rises by one step and is in position, when the distance to the paper is the largest (position "max")that takes place during the printing on the disk, such as CD-R. moreover, if in a state where the protruding portion a is retained by the obstacle, the carriage 50 is moved in the direction b, the carriage 50 can be returned to its original position. Printing device corresponding to this implementation variant of the present invention, are made so as to using this mechanism, there is a possibility to adjust the distance to the paper in three stages, according to the media type of printed information.

Figa-15C are drawings each of which shows the relationship between the moving support 1301 and locking mechanism of the pickup roller when the carriage is moved to the lock position if the distance to the paper is in the normal position, the position of the "thick paper" and the position "max" respectively. As shown in Figa and 15, is even if the carriage 50 is moved to the lock position in the normal position or the position of a "thick paper", the protruding portion a remains out of contact with the rocker lever 4003 block; as a result, the rocker lever 4003 lock will not turn. That is, the function as a starting tool becomes prohibited. On the other hand, as shown in Figs, when the distance to the paper is set to "maximum", if the carriage 50 is moved to the lock position, the protruding portion a contact with the beveled part a rocker lever 4003 block; as a result, the rocker lever 4003 lock is rotated in the CW direction. That is, the function as the starting funds remains permitted. Moreover, the device is designed so that the force of rotation of the rocker lever 4003 lock could be substantially less than the force that causes the sliding of the slider 1302 switching of the distance to the paper, to prevent displacement of the slider 1302 when turning the rocker lever 4003 lock.

Figa and 16B are drawings used to explain the distance to the paper and the carriage 50 in this embodiment implementing the present invention. When the media printed information has a fixed size, such as plain paper, special paper or thick paper to print on all media Pecatonica in the direction of its width, the carriage performs the reciprocating movement within the range specified on Figa arrow, made a solid line. That is, the carriage 50 during printing is moved in the lock position. However, as the distance to the paper is either the normal position or the position of the "thick paper", even when the carriage 50 reaches the position of the locking protruding portion a does not come into contact with the beveled part a rocker lever 4003 block, and, therefore, the rocker lever 4003 lock does not turn.

In the case when the carrier printed information is a CD-R, the carriage must be moved only within the range specified on FIGU arrow, made a solid line, and it does not move the print to the lock position. That is, there is no possibility of blocking the pickup roller 36 in the middle of printing operation on the CD-R. on the other hand, when receiving information about the initial position of the pickup roller 36 a distance to the paper, is set to the maximum, and the carriage is moved to the lock position, indicated by the arrow, made by a dotted line.

Fig is a block diagram serving to explain the steps of the process performed by the CPU 501 for determining the initial position of the pickup roller 36.

In order not to block the pickup roller 36 in the middle of a printing operation, it is necessary that the rocker lever 4003 block and in contact with him starting means on the carriage 50 in contact with each other outside of the zone of displacement, when the carriage 50 prints. That is, in the case when the starting means, as in the first embodiment implementing the present invention is used, the protruding portion 50A provided at the back side of the carriage 50, as the zone of permissible movement of the carriage 50, required area, representing the area of movement required to perform the print operation is and the media printed information of a fixed size, with the added width position lock. As a result, in the printing device corresponding to the first variant implementation of the present invention, it becomes necessary width greater than the width shown in Fig, added width position of the lock that leads to the increase in size of the device compared to the variant of realization of the present invention. In the printing device corresponding to this implementation variant of the present invention, the lock position in the printing device is in the normal print area, when the print area is wide, and becomes locked position, only if the print area is narrow. Due to this, information about the initial position of the pickup roller can be obtained without increasing the size of the printing device, in contrast to the first variant of implementation of the present invention.

When the above-described construction, if the print medium printed information of a fixed size at a distance of paper in position "max", it will be impossible to divide the normal printing operation and a receive operation start position. However, even in a case like this, if you can further expand the area of the stroke of the slider, in which you specify the same distance to the paper, and that the ONU to align with two positions of the slider 1303 switching of the distance to the paper, it is possible to solve the above problem.

On Figa and 17B shows the design to implement a two-step change of the distance to the paper, and they are drawings used to explain the structure in which the area of the stroke position of the distance from the paper to be brought into compliance with two provisions of the slider 1303 switching of the distance to the paper. Figa is a drawing illustrating the relative position of the slider 1303 switching distance up the paper and sliding support 1301 when the distance to the paper is great, and you perform a normal print. On the other hand, Figv is a drawing illustrating the relative position of the slider 1303 switching distance up the paper and sliding support 1301-time information on the start position. Although in either state, the distance to the paper is set large, the design of the printing device allows the following: able to Figa, when the carriage 50 is moved to the lock position, the protruding portion does not come into contact with the rocker lever lock; and able to Figv the protruding portion comes into contact with the rocker lever lock to block the pickup roller.

As described above, according to this variant implementation of this izaberete the Oia printing device has such a construction, that the protruding portion provided on the slider switch of the distance to the paper, can be used as a starting tool to lock the pickup roller, and use the slider to switch the distance to the paper, you can enable or disable the function of the starting means. Thus, it is possible to realize the same effect as in the first embodiment implementing the present invention, without increasing the size of the printing device.

A third option

In this embodiment, is also used printing device explained with reference to Figures 1-5. However, in this embodiment implementation of the present invention the pickup roller block, using the starting element, which is driven by the motor load. As shown in figure 1, the printing device corresponding to this implementation variant of the present invention has such a construction that the loading roller 28 can be driven in rotation in the direction of the load carrier of printed information by an electric motor 99 load, making the rotation in the positive direction, and therefore can run rise of the pressure plate 21. When performing this series of operations inside the device is loaded one sheet of paper from a variety of printed media, which is in the top position. P is this all what needs to be done to prevent the rise of the pressure plate 21 before the loading roller 28 rotates forward by a specified amount, is just to ensure the well-known delay mechanism to actuate and lock independent of the magnitude of the rotation. Note that in a state where the pressure plate is not raised in this mechanism, as while waiting to load media print information if the motor load 99 is rotated by a fixed amount in any direction, the positive direction or the reverse direction, the loading roller 28 is not in contact with the carrier printed information and the media does not move. In this embodiment implementation of the present invention the actuator element is made in such a way as to operate in the normal and reverse rotations of the loading roller 28 by a specified amount in a state where the pressure plate 21 does not rise, which allows to obtain the initial position of the pickup roller 36.

Figa and 19C are views in section, serve to explain the steps by which the lock function in the printing device corresponding to this implementation variant of the present invention. The starting element 1901 is connected with the loading roller 28 by means of rotary is clenenia based on friction (joint with torque limiter) and implemented in such a way so it can be rotated in the position shown in Figa when loading the roller 28 is rotated in the forward direction, and could be rotated in the position shown in Figv when loading the roller 28 is rotated in the opposite direction. Upon receipt of the initial position, if the loading roller 28 is rotated in the reverse direction by a specified amount in a state where the pressure plate 21 is omitted, the starting element 1901 rotates in the CW direction. When the trigger element is turned to a predetermined position (lock position), the lever portion a starting element 1901 comes into contact with the protruding part I available on the rocker lever 4003 block, and pushes this part in a downward direction, which causes the rocker lever 4003 lock to turn. If in this state, the pickup roller 36A is driven in the CW direction, the stopping lever 4002 rocker lever 4003 block included in the concave section a locking ring 4001 due to the same mechanism as in the above-described implementation of the present invention, the pickup roller 36A is blocked (suspended), and as a result you can get information about the start position.

After that, if the starting element 1901 return to the position shown in Figa, forcing the loading roller 28 POWERCIAT is camping in the forward direction, and then the pickup roller 36 is put into rotation in the direction CW, the locked condition is removed due to the force applied by the spring 4004 stopping lever.

As described above, according to this variant implementation of the present invention, the initial position of the pickup roller can be obtained with high accuracy, providing a starting means, which is connected with the loading roller 28 by means of the rotational joint on the basis of friction, without installing a new electronic device and the wiring for it.
