(5) the Effects of cartridge manifestations

Cartridge manifestations 30 having the above structure, the contact plate 122 of the electrode element 117 is located in the plane of projection, when the input gear 94 is projected in the direction of parallel the nom shaft 52 showing the platen, which is the first direction. More specifically, the contact plate 122 of the electrode element 117 is located in the plane of projection, when the driven connecting part 100 is projected in the first direction. In some aspects, the contact plate 122 is in contact with the terminal 131 voltage processor displacement in the plane of projection, when the driven connecting part 100 is projected in the first direction. In particular, the contact plate 122 is in contact with the terminal 131 voltage processor offset by continuing the line of the supporting shaft 99 of the input gear, which rotates the driven connecting part 100. In addition, the first axial line X1 and the second axial line x2 are parallel to each other. Part of the contact plate 122 of the electrode element 117 is located on the second axial line x2. More specifically, the first line L1 and the second line L2 parallel to each other, and the first distance D1 and second distance D2 are equal.

Therefore, even when the cartridge manifestations of 30 applications such rotational or torsional power, which creates a rotation or torsion cartridge manifestations of 30 around the input gear 94, when the driving force from the motor is applied to the driven connecting part 100 from the host connecting part 200, it is possible to prevent significant impacts rotational or cool is through the power contact plate 122 of the electrode element 117. Therefore, prevents the exit of the contact plate 122 from his position. Thus, the contact plate 122 and the terminal 131 of the voltage developing bias are in sliding contact with each other, thereby stably supplying power to the electrode element 117 on the shaft 52 showing the platen.

If the point of contact between the contact plate 122 and the terminal 131 of the voltage developing bias is in any position in the plane of projection, when the driven connecting part 100 is projected in the first direction, you can minimize the impact of any rotational or torsional capacity.

In addition, in the cartridge manifestations of 30 each end showing the roller 38 supported in the left and right side walls 69L, 69R due to the fact that each end of the shaft 52 showing the roller rests rotatably in the left or right side walls 69L, 69R. Accordingly, when showing the platen 38 is firmly supported, can be stably applied voltage developing bias to the rubber roller 53.

One end of the shaft 52 showing the roller rests rotatably in part 111 for inserting the shaft showing the platen cover 93 of gear wheels by means of the coupling element 116. The other end of the shaft 52 showing the roller rests rotatably in part 118 that covers the shaft proabley the th roller, electrode element 117. Each end showing the roller 38 is also based in part 111 for inserting the shaft showing the platen cover 93 gears or part 118 that covers the shaft showing the roller electrode element 117. Thus, showing the roller 38 can be securely supported, and the shaft 52 showing the roller is effectively inserted in part 111 for inserting the shaft showing the platen cover 93 gears or part 118 that covers the shaft showing the roller electrode element 117. Therefore, it is possible reliable application of the voltage developing bias to the rubber roller 53.

Electrode element 117 in the cartridge manifestations 30 is made of conductive resin. Therefore, the electrode element 117 can be formed in any shape for the application of the voltage developing bias to the rubber roller 53.

Driven connecting part 100 is made in the form of the ring gear and limiting the engagement pieces 102, protruding radially inward from the inner peripheral surface of the driven connecting part 100. Therefore, when restricting engagement portion 102 is introduced into engagement with the lead connecting part 200, is possible reliable transmission of the driving force with the leading connecting part 200.

Since the driving wheel 101 of the input gear 94 is entered engages directly with the leading toothed wheel 115 showing the roller, the driving force is supplied from the host connecting part 200 to the input gear wheel is transmitted directly to the drive sprocket 115 showing the roller from the input gear. Therefore, it is possible reliably showing rotation of the roller 38. In addition, when the driving force is transmitted thus, the driving force is transmitted from the main body 2 directly to the drive sprocket 115 showing the roller, as a result, you can use the shaft 52 showing the roller as a guide. More specifically, when the cartridge 30 manifestations installed in the part 147 to install cartridge manifestations, the stub element 116 and the portion 118 that covers the shaft showing the roller provided on the shaft 52 proyavlyayuschego the roller, travel along the guide grooves 153.

The drive sprocket 101, the input gear 94 also introduced engages directly with the leading toothed wheel 95, feed roller, whereupon the driving force supplied from the host connecting part 200 to the input gear wheel 94 is transmitted directly to the drive sprocket feed roller 95. Consequently, it is possible to provide a reliable rotation of the feed roller 37. In addition, when the driving force is transmitted thus, the driving force is transmitted directly from the input gear 94 to the drive sprocket 115 showing the roller and the drive sprocket feed roller 95. Thus, there is the possibility of effective transmission of the driving force, and provide a solid showing rotation of the roller 38 and the feed roller 37.

Electrode element 117 is supplied with part 118 that covers the shaft showing the cushion, and part 127, closing shaft, feed roller. Accordingly, it appears possible reliable support shaft 52 showing the roller and the shaft 50 of the feeding roller on the part 118 that covers the shaft manifesting in the face, and part 127, closing shaft, feed roller, respectively.

When the cartridge 30 manifestations installed in the main casing 2, the terminal 131 of the voltage developing bias is in elastic contact with the upper surface portion 118 that covers the shaft showing the cushion, and part 127, closing shaft, feed roller, and a front surface facing the shaft of the feed roller 50. Therefore, it is possible to achieve a reliable contact between the terminal 131 of the voltage developing bias and the contact plate 122. Thus, it appears possible for the reliable application of the voltage developing bias using circuit Board high voltage (not shown) to the contact plate 122 through terminals 131 voltage processor offset.

When the cartridge 30 manifestations installed in the part 147 to install cartridge manifestations of the frame 58 of the drum, the front ends of the bosses 132 are in contact with the respective clamping levers 150. Under the influence of driving force of a compression spring that forces the movement of the clamping levers 150, the respective clamping lever 150 has on every boss 132 push backward. Thus, showing the roller 38 is pressed against the photoconductor drum 28.

The cartridge 30 manifestations corresponding to certain aspects, has a mechanism 92 jagged stake and the cover 93 of gear wheels, similar to those that are in the cartridge manifestations of 30, corresponding to the previously described aspects.

(3) Electrode

The cartridge 30 manifestations corresponding to some aspects, has an electrode element 117, similar to that which is in the cartridge manifestations of 30, corresponding to the previously described aspects.

On the front side of the bearing member 201 has an opening 161. When the supporting member 161 is fixed to the right side wall 69R, the shaft 52 showing the roller 52 is inserted in the sleeve portion 202 and the shaft feed roller 50 is inserted into the hole 161. To prevent a situation in which a cylindrical portion 79 of the screw that extends outward from the right sidewall 69R in the first direction, prevents the bearing element 201, as part of an external periphery of the bearing member 201, where the cylindrical portion 79 of the screw made the cut. When the supporting member 201 is fixed to the right side wall 69R, the cylindrical portion 79 of the screw is open with the outer periphery of the bearing member 201.

Electrode element 117 as an electrode for voltage application developer bias to the shaft 52 showing the roller is made separately from the support member 201 on the right side wall 69R, so that part of the bearing member 201 is located between the right side wall 69R and electrode element 117. As shown in Fig, the reservoir is at 123 basis as fasteners electrode element 117 is parallel to the mounting plate 120 in the outer position from the mounting plate 120 with respect to the first direction. As shown in Fig and 22, the hole 140 of the screw as a part for inserting performed essentially in the Central part of the plate 123 of the base. In connection with the free end 79A of the cylindrical part 79 of the screw, the hole 140 of the screw has an essentially oval shape with flat parts, which take place in a direction from front to back.

External rib plate 124 is held in the first direction from the outer periphery of the plate 123 of the base, connecting plate 123 and the mounting plate 120. In the cartridge 30 manifestations corresponding to some aspects, the electrode element 117 is attached to the right sidewall 69R as follows. First, the ends of the shaft 52 showing the roller and the shaft of the feed roller 50 is inserted into the portion 118 that covers the shaft showing the cushion, and part 127 covering the shaft, feed roller, respectively. The cylindrical portion 79 of the screw provided on the right sidewall 69R, is inserted into the hole 140 of the screw in the plate 123 of the base, pulling the free end 79A of the cylindrical part 79 of the screw into the hole 140 of the screw. After that, the screw 130 as the fastener is screwed into the cylindrical portion 79 of the screw, the open side plate 123 of the base.

The screw 130 is made as a unit with the rod 130A, with the coils of the helical thread made along its axial direction, and heads the Oh 130b screw, provided on the end of the rod 130A as to prevent separation of the parts, which runs like a mushroom in the radial direction of the rod 130A. The diameter of the head 130b of the screw is the same as the diameter of the cylindrical part 79 of the screw, or somewhat larger.

As shown in Fig and 25, the screw 130 is screwed into the cylindrical portion 79 of the screw up until the internal with respect to the axial direction of the screw - end If head 130b of the screw does not come into contact with the free end of the Ff as the third end face of the cylindrical part 79 of the screw.

When the electrode element 117 is thus attached to the right sidewall 69R, the mounting plate 120 located between the part 118 that covers the shaft showing the cushion, and part 123 of the base, in contact with the supporting member 201, so that the electrode element 117 is positioned relative to the first direction (the width direction of the cartridge manifestations of 30). The free end of the Ff cylindrical part 79 of the screw is located so that it is slightly (for example, 0.2 mm) protrudes outward in the first direction to the side of the head 130b screw from the outer faces Of the first end plate 123 of the base.

Internal with respect to the axial direction of the screws 130 - butt head 130b of the screw is in contact with the free end face If of the cylindrical part 79 in the NT and refers to an outer face Of the plate 123 of the base, at the same above and below the rod 130A screw has a small distance (for example, 0.2 mm). Head 130b screw located in a position opposite to the free end of the Ff cylindrical part 79 screw, restricts or prevents the separation plate 123 of the base from the cylindrical part 79 of the screw or remove the said plate from this part.

Due to the distance between the inner with respect to the axial direction of the screw - end If head 130b of the screw and the outer face Of the plate 123 of the base electrode element 117 not come into tight contact with the outer face Of the plate 123 of the base. Accordingly, the electrode element 117 is able to make small movements due to the presence of a small gap between the electrode element 117 and the cylindrical portion 79 of the screw. When the terminal 131 voltage with the offset provided in the main casing 2, is in elastic contact with the upper surface of the contact plate 122, the portion 118 that covers the shaft showing the cushion, makes a small move within range of the small gap between the electrode element 117 and the cylindrical portion 79 of the screw. Accordingly, the outer circumferential surface of the shaft end 52 showing the roller is in sliding and tight contact with the inner circumferential surface portion 118 that covers the shaft p is aawsome roller. Thus, the end of the shaft 52 showing the roller rests rotatably on the part 118 that covers the shaft showing the platen. Part 127, closing shaft, feed roller, also makes moving within range of the small gap. Therefore, the outer circumferential surface of the shaft end 50 of the feed roller is also provided in a sliding and tight contact with the inner circumferential surface portion 127, the closing shaft, feed roller. Thus, the end of the shaft 50, feed roller rests rotatably on the part 127, closing shaft, feed roller.

Accordingly, because the outer circumferential surface of the shaft end 52 showing the roller is in secure contact with the inner circumferential surface portion 118 that covers the shaft showing the roller, the shaft 52 showing the roller rotates. In other words, the portion 118 that covers the shaft showing Wali is a, rests rotatably on the shaft 52 showing the roller and the electrode element 117 moves so that the portion 118 that covers the shaft showing the roller comes into reliable contact with the shaft 52 showing the platen, when the terminal 131 of the voltage developing bias is in contact with the contact plate 122. Therefore, it becomes possible reliable application of the voltage developing bias terminal 131 of the voltage developing bias to the shaft 52 showing the platen by means of the contact plate 122 and part 118 that covers the shaft showing the platen.

The electrode element in the cartridge manifestations 30 is securely attached to the right sidewall 69R with a screw 130 so that the electrode element can make a small move within the small gap.

More specifically, when the internal with respect to the axial direction of the screws 130 - end If the screw head is in contact with the free end face Ff of the cylindrical part 79 of the screw, the head 130b of the screw and the plate 123 of the base are arranged so that between them there is some distance. Thus, it becomes possible to ensure the distance between the outer face Of the plate 123 of the base and the inner end face If the head 130b screws accurately and reliably. So, it becomes possible reliable contact portion 118, closing Valparaiso roller, with the shaft 52 showing the roller with a guarantee smooth rotation of the shaft 52 showing the roller with respect to part 118 that covers the shaft showing the platen.

Cartridge manifestations of 30 part 118 that covers the shaft showing the roller and the contact plate 122 is provided protruding outward in the first direction from the right sidewall 69R along the shaft 52 showing the platen. Therefore, as the contact plate 122 is in reliable contact with the terminal 131 of the voltage developing bias, it is possible to ensure smooth rotation of the shaft 52 showing the roller with respect to part 118 that covers the shaft showing the platen, and to ensure reliable contact portion 118 that covers the shaft showing the roller with the shaft 52 showing the platen.

Cartridge manifestations of 30 part 127, closing shaft, feed roller, provided with electrode element 117. Because the shaft of the feed roller 50 is firmly supported in part 127, closing shaft, feed roller, there is also the possibility of application of the voltage developing bias to the shaft of the feed roller 50.

Cartridge manifestations of 30 supporting member 201 is provided on the right sidewall 69R separately from the electrode element 117. Since the supporting member 102 may be shaft 52 showing the roller or to serve him support, you receive a reliable contact portion 118, close the covering of the shaft showing the platen, with the shaft 52 showing the roller with a guarantee smooth rotation of the shaft 52 showing the platen. Even when the element cannot be used as an electrode, it is possible to reliably supply power to the shaft 52 showing the platen.

(5) the Electrode element corresponding to other aspects
