The functions and effects of Delevoping cartridge 10 to forming as described above illustrate.

As shown in Figure 1, when assembling Delevoping cartridge 10 to laser printer 1, with developer roll 12 for file leader and along third party To mobile Delevoping cartridge 10.

In addition, the state of initial position is in for unused state as Fig. 1 i.e. detection gear 200 in Delevoping cartridge 10 Under, the top of the first projection 261 is exposed from the opening 31A of second gear cover 31.Therefore, the top of the first projection 261 and bar 7A Contact and swing bar 7A.As described above, when optical sensor 7B detects the displacement of bar 7A, control device CU can determine that for It is equipped with Delevoping cartridge 10.It should be noted that when detection gear 200 is in initial position, the second projection 262 is not from opening 31A exposes, therefore is not contacted with bar 7A.

In addition, as shown in (a) of Fig. 9, detection gear 200 is in initial position from helical torsional spring 37 to direction of rotation Force, but the top of the second rib 230 contacts and is prevented with the first rib 120 of the second blender gear 100, therefore detect tooth Wheel 200 can not rotate.Moreover, the first gear portion 110 of the second blender gear 100 and the toothless portion) 221B of detection gear 200 Relatively.

When laser printer 1 starts driving according to the instruction of control device CU, as shown in figure 4, shaft coupling 22 rotates, And the first blender gear 25 is caused to rotate via idler gear 26.Then, first direction is caused via blender 14 Second blender gear 100 of opposite side rotates.

Shown in (a), (b) such as Fig. 9, when the second blender gear 100 is rotated to the direction of arrow, the second blender gear 100 first gear portion 110 with detect gear 200 toothless portion) 221B it is opposite, therefore will not from the second blender gear 100 to Detect gear 200 and transmit rotary force.When the second blender gear 100 rotates, the top of the second rib 230 is in first rib 120 Slided on outer circumferential surface.

When the second blender gear 100 rotates, as shown in (a) of Figure 10, the disconnected 125 of first rib 120 is close to The top of two ribs 230.As shown in (b) of Figure 10, when the disconnected 125 of first rib 120 is opposite with the second rib 230, because spiral The active force of torsionspring 37 and detect gear 200 and rotate, the top of the second rib 230 enters the disconnected 125 of first rib 120. The gear teeth 221 in second gear portion 220 engages with the gear teeth 111 in first gear portion 110.That is, the second blender gear 100 into For the 5th position.

When first gear portion 110 engages with second gear portion 220, the rotary force of the second blender gear 100 can be to inspection Survey gear 200 to transmit, thus, detection gear 200 rotates together with the second blender gear 100.Thus, as Figure 11 (a)~ (c) like that, detection gear 200 is rotated with First Speed.

When detecting the rotation of gear 200, as shown in (a) of Figure 11, bar 7A is located at the first projection 261 and the 4th projection 263 Between.That is, any one projection in the first projection 261, the second projection 262 and the 4th projection 263 is not contacted with bar 7A.By This, bar 7A is not located between the light-projecting portion and light accepting part of optical sensor 7B, and optical sensor 7B received signals change.

When detection gear 200 further rotates, as shown in (b) of Figure 11, the 4th projection 263 is contacted with bar 7A.Thus, Bar 7A is located between the light-projecting portion and light accepting part of optical sensor 7B, and optical sensor 7B received signals change.

When detection gear 200 further rotates, as shown in (c) of Figure 11, bar 7A is prominent positioned at the 4th projection 263 and second Rise between 262.That is, any one projection in the first projection 261, the second projection 262 and the 4th projection 263 does not connect with bar 7A Touch.Thus, bar 7A is not located between the light-projecting portion and light accepting part of optical sensor 7B, and optical sensor 7B received signals become Change.

When detection gear 200 further rotates, as shown in figure 12, the gear in the second gear portion 220 of gear 200 is detected The gear teeth 111 in tooth 221 from the first gear portion 110 of the second blender gear 100 leaves and 220 and first tooth of second gear portion The engaging of wheel portion 110 releases.Thus, the rotary force of the second blender gear 100 is no longer transmitted to detection gear 200.However, this When, the first arm 37B of helical torsional spring 37 contact with detecting the second spring holding section 252 of gear 200 and to detection gear 200 apply rotary force.Therefore, detection gear 200 is consumingly accelerated by the active force of helical torsional spring 37, detect tooth Wheel 200 is rotated with the second speed faster than First Speed to the counter clockwise direction of Figure 12.

Also, as shown in (a) of Figure 13, (b), after detection gear 200 rotates at a high speed, the 3rd projection 270 with it is locking When projection 31C is contacted, detection gear 200 stops, and detection gear 200 becomes final position.

At the final position shown in (a), (b) in Figure 13, the second projection 262 is exposed from opening 31A and is contacted with bar 7A. Thus, bar 7A is located between the light-projecting portion and light accepting part of optical sensor 7B, and optical sensor 7B received signals change.Such as figure Shown in 13 (a), when detection gear 200 is in final position, the tooth in the first gear portion 110 of the second blender gear 100 The gear teeth 111 are opposite with the toothless portion) 221B for detecting gear 200, do not engaged with any one tooth in multiple gear teeth 221.And And detection gear 200 directed through helical torsional spring 37, locking projection 31C, the 3rd projection 270 and keep, therefore, with Even if the second blender gear 100 rotates afterwards, detection gear 200 will not rotate.

During action more than, after detection gear 200 starts rotation, the output switching four of optical sensor 7B It is secondary.The pattern (length or switching times of OFF signal or ON signals or the difference of switching timing) of the switching of the output can lead to Rotating number of projection or the size of direction of rotation are crossed together with detection gear 200 to change.By making the signal in advance Pattern (pattern) is corresponding with the specification of Delevoping cartridge 10, and control device CU can differentiate the specification of Delevoping cartridge 10.

In the case of the body shell 2 of laser printer 1 is assemblied in using the Delevoping cartridge 10 for the state that finishes, gear is detected 200 are in final position.Even in this case, the top of the second projection 262 is also at first with the unused state The roughly the same position of projection 261.Therefore, when by being assembled using the Delevoping cartridge 10 finished to body shell 2, the second projection 262 top is contacted with bar 7A, therefore control device CU can determine that to be assembled with Delevoping cartridge 10.It should be noted that examining Gear 200 is surveyed when being in final position, perhaps the first projection 261 can expose a part from opening 31A, but due to from the second projection 262 leave, therefore will not be contacted with bar 7A.

Delevoping cartridge 10 from the description above, can make detection gear 200 with First Speed from first position to second Put rotation, and by the active force of helical torsional spring 37 make detection gear 200 with the second speed faster than First Speed from The second place is rotated to the third place.That is, the new structure for the specification for being used to determine Delevoping cartridge 10 can be realized with simple structure Make.

In addition, the phase contacted in the second rib 230 for detecting gear 200 with the first rib 120 of the second blender gear 100 Between, even if the second blender gear 100 rotates, detection gear 200 will not rotate.Also, the second blender gear 100 from After 4th position is rotated to the 5th position, the second rib 230 is not contacted with first rib 120, detects 200 and second blender of gear Gear 100 rotates together.Therefore, it is possible to after it have passed through specified time limit since rotation making the second blender gear 100 Make detection gear 200 start to rotate, therefore can realize the variation of the action of detection gear 200.

More than, although embodiment of the present disclosure is illustrated, the disclosure is not limited to the embodiment.Close In specific structure, can suitably be changed in the range of the purport of the disclosure is not departed from.

In the above-described embodiment, the first projection 261, the second projection 262 and the 4th projection 263 can be with detecting gear 200 rotate together, but the first projection 261, the second projection 262 and the 4th projection 263 be not limited to can with detect gear one Play rotation.For example, each projection can also be the projection with detecting gear split.In this case, detection gear can have convex Wheel.Specifically, detection gear can be moved with the rotation of shaft coupling, the state or cam contacted by cam with projection With the passage of the discontiguous state of projection, and move projection.For example, it may be the structure that projection linearly moves.Need Illustrate, as long as projection can move bar 7A.

In the above-described embodiment, detecting gear 200 has the 4th long in a rotational direction projection 263, but detects The projection for being used to move bar 7A that gear 200 has is not limited thereto.
