Opening 230 is the opening connected with the left side of its opposition side on the right side of Delevoping cartridge 7 being configured with framework 200, if It is placed in the lower section in axle portion 220.Abutting part 124 is when detection part 100 is assembled in framework 2, by opening 230 at framework The side being configured with Delevoping cartridge 7 of 200 is exposed.Owing to opening 230 allows the rotation of abutting part 124, therefore from rotating shaft direction During observation, be formed as the substantially arcuation centered by axle portion 220.

The one end of the rotating shaft direction of the second detection part main body 121 of detection part 100, specifically right side End 121A abuts with framework 200, thus is positioned framework 2 on rotating shaft direction.Tapping screw 91 warp of detection part 100 It is screwed into the hole portion 221 in axle portion 220 by packing ring 92, thus is installed on framework 2.

As shown in Figure 6, spring holding section 240 is the part that the end with stretching spring 160 (with reference to Fig. 8) engages, and arranges Face in the left side of framework 200.Specifically, spring holding section 240 is prolonged to the left in the position from the front obliquely downward in axle portion 220 After stretching, be formed as forwards extending is hook-shaped.

First limiting unit 250 is to limit the portion that the first detection part 110 rotates to the second direction of rotation R2 (with reference to Fig. 8) Point, it is arranged at the face in the left side of framework 200.Specifically, the first limiting unit 250 is arranged to the lower section of retreading from axle portion 220 Position highlight to the left.The face of the upside of the first limiting unit 250 is formed as plane, it is possible to the first of detection part 100 Restricting portion 117 abuts.

As shown in Figure 8, the stretching spring 160 as the first force application part is to the second direction of rotation R2 relative to framework 2 The parts that first detection part 110 (detection part 100) is exerted a force.The one end of stretching spring 160 and the first detection part 110 The first spring holding section 114 engage, the other end engages with the spring holding section 240 of framework 2.

Stretching spring 160 is stretched further than natural length, thus via the first spring holding section 114 to the first detection Parts 110 exert a force to the second direction of rotation R2.First restricting portion 117 and frame of the first detection part 110 (detection part 100) First limiting unit 250 of body 2 abuts, and thus limits further to the rotation of the second direction of rotation R2.Detection part now The state of 100 is above-mentioned " non-detection posture ".

Then, the action to detection part 100 illustrates.

When under the state that the Delevoping cartridge 7 (handle box 5) in the new product state shown in Fig. 4 (b) is installed on framework 2, at the beginning of execution During beginning spinning movement, driving force is transferred to detect the gear tooth 77G of gear 77 via agitator gear 75G (with reference to Fig. 2 (b)) And make detection gear 77 rotate.

Then, as shown in Fig. 9 (a), detected portion 79 by detection gear 77 rotation and to a direction, specifically Diagram the most irreversibly rotates (movement), and detected portion 79B abuts with the first bearing surface 124A of abutting part 124.Further, When detected portion 79 rotates further, as shown in Fig. 9 (b), the first bearing surface 124A of abutting part 124 is to detected portion 79B Pressing thus detection part 100 overcome stretching spring 160 active force and to first direction of rotation R1 rotate.

Now, the restricting portion 122 and the second of the first detection part 110 of the second detection part 120 of detection part 100 Limiting unit 116 abuts, thus produce because the first bearing surface 124A of the second detection part 120 presses to detected portion 79B It is transferred to the first detection part 110 via restricting portion 122 and the second limiting unit 116 to the revolving force of the first direction of rotation R1, First detection part 110 also rotates with the second detection part 120 1 first direction of rotation R1 in the same direction.That is, detection part 100 to When first direction of rotation R1 rotates, the first detection part 110 and the second detection part 120 unitary rotation.

Further, thus, when the shading arm 118 of detection part 100 is from the illuminating part 151 of optical sensor 150 and light When making a concession between portion 152, shown in dotted line, accept by light accepting part 152 owing to carrying out the light of self-luminescent part 151, therefore light accepting part 152 The signal of regulation is exported to controlling device.Its result is, controls device and is judged to that installed Delevoping cartridge 7 is new product.

Further, detected portion 79 rotates further, thus as shown in Fig. 9 (c), when detected portion 79B crosses abutting part 124 Time, detection part 100 rotates to the second direction of rotation R2 because of the active force of stretching spring 160.Further, the first restricting portion 117 abut with the first limiting unit 250, thus detection part 100 returns non-detection posture, and shading arm 118 is re-introduced into luminescence Between portion 151 and light accepting part 152, the light penetrated towards light accepting part 152 from illuminating part 151 is blocked.

Then, detected portion 79 rotates further, although thus illustrating and omit but in detected portion 79C and detected portion When 79D and the first bearing surface 124A abuts, detection part 100 also rotates to the first direction of rotation R1, from light accepting part 152 to control The signal of device output regulation.Control device in the execution of initial rotation action, according to the quantity of detected portion 79, according to from The number of times of the signal of light accepting part 152 output regulation judges the specification of installed Delevoping cartridge 7.

Further, as shown in Fig. 9 (d), after detected portion 79D crosses abutting part 124, when the toothless portion) of detection gear 77 77N and agitator gear 75G relative to time, due to driving force be not delivered to detect gear 77, therefore detection gear 77 stop, tested The rotation in survey portion 79 also stops.Further, then, even if Delevoping cartridge 7 is in drive transmission mechanism 76 and is driven detected portion 79 The old product state not rotated.

Under the state that the Delevoping cartridge 7 (handle box 5) of old product state is installed on framework 2, even if performing initial rotation action, Detected portion 79 also will not rotate thus detection part 100 does not carry out action, therefore controls device and is judged to that Delevoping cartridge 7 is old Product.

As shown in Figure 10 (a), in the execution of initial rotation action, lid 21 or the electricity of laser printer 1 before opening In the case of source comes off, owing to the input of the driving force from drive transmission mechanism 76 stops, the most such as 1 detected portion 79 just past under the state after abutting part 124, and the rotation of detected portion 79 stops in midway sometimes.

In this case, if dismantling Delevoping cartridge 7 (handle box along handling guiding piece 210 to disassembly direction from framework 2 5), then as shown in Figure 10 (b), detected portion 79 abuts with the second bearing surface 124B of abutting part 124.If wanted from this state Further demounting process cartridge 5, then as shown in Figure 10 (c), the second bearing surface 124B of abutting part 124 by detected portion 79 press from And the second detection part 120 overcomes the active force of torsionspring 130 to rotate to the second direction of rotation R2.

Now, owing to the first detection part 110 abuts with the first limiting unit 250 of framework 2 because of the first restricting portion 117 and Being limited the rotation to the second direction of rotation R2, therefore the only second detection part 120 of detection part 100 is relative to the first detection Parts 110 and framework 2 rotate to the second direction of rotation R2.That is, abutting part 124 is applied as with the first direction of rotation R1 phase During the power of second direction of rotation R2 in anti-direction, the second detection part 120 of detection part 100 is relative to the first detection part 110 rotate.

Then, when being made detected portion 79 pass through near detection part 100 by further demounting process cartridge 5, such as figure Shown in 10 (d), detected portion 79 crosses abutting part 124, the second detection part 120 because of the active force of torsionspring 130 to the One direction of rotation R1 rotates.Further, restricting portion 122 abuts with the second limiting unit 116, thus the second detection part 120 returns To original posture.

Present embodiment from the description above, detection part 100 has the first detection part 110 and the second detection part 120, the second detection part during owing to applying the power of oriented second direction of rotation R2 at the abutting part 124 of the second detection part 120 120 rotate relative to the first detection part 110 and framework 2, therefore, it is possible to suppression applies less desirable power to detection part 100 Situation.

Further, owing to having stretching spring 160, framework 2 has the first limiting unit 250, is therefore applying abutting part 124 When the power of the first direction of rotation R1, the second detection part 120 presses the second limiting unit 116 such that it is able to make the first detection Parts 110 overcome the active force of stretching spring 160 to rotate to the first direction of rotation R1.Thereby, it is possible to make the first detection part 110 and second detection part 120 integratedly to first direction of rotation R1 rotate.

On the other hand, owing to having torsionspring 130, the first detection part 110 has the second limiting unit 116, therefore exists Abutting part 124 is applied with when the power of the second direction of rotation R2, limits the first detection part by the first limiting unit 250 110 to the rotation of the second direction of rotation R2 such that it is able to only make the second detection part 120 overcome the active force of torsionspring 130 And rotate to the second direction of rotation R2.

Further, as shown in Fig. 4 (b), due to the first bearing surface 124A and the second direction the most different for bearing surface 124B Extend, therefore, it is possible to according to the moving direction of detected portion 79 set respectively the first bearing surface 124A towards with the second bearing surface 124B towards.Thereby, it is possible to make detection part 100 rotate well.

Further, it is along by the pivot center 100A of detection part 100 and detected portion due to the first bearing surface 124A The face of plane PL of the pivot center 79A of 79, therefore when the detected portion 79 rotated abuts with the first bearing surface 124A, it is possible to Power is made to be transferred to the first bearing surface 124A well.Thereby, it is possible to make the first detection part 110 and the second detection part 120 1 Rotate well to the first direction of rotation R1 body.

Further, it is that more radial outside towards detection part 100 is located the second rotation side due to the second bearing surface 124B To the face in the downstream of R2, therefore when the detected portion 79 moved to disassembly direction abuts with the second bearing surface 124B, it is possible to The second detection part 120 will not be made in the case of second bearing surface 124B (detection part 100) is applied excessive power to Two direction of rotation R2 rotate.

Further, as it is shown in fig. 7, due to axle portion 220 be arranged to from framework 200 towards with the side being configured with Delevoping cartridge 7 Opposition side, specifically left and right directions protruding outside, the most certainly can in the axle portion 220 assembling before framework 2 group Dress detection part 100, even if also be able to detection part 100 is assembled in axle portion 220 after framework 2 is assembled certain degree On.Thereby, it is possible to improve the degree of freedom of the assembling of detection part 100.Further, due to framework 200 be configured with Delevoping cartridge 7 Side opposition side configuration detection part 100 major part, therefore, it is possible to suppression detection part 100 abutting part 124 beyond Part and drum unit 6 or the interferenceing of Delevoping cartridge 7.

Further, owing to the end 121A of the second detection part main body 121 of detection part 100 abuts with framework 200 thus Be positioned on rotating shaft direction relative to framework 2, therefore need not additionally to be provided for be positioned detection part 100 against Portion.Thereby, it is possible to detection part 100 is positioned framework 200 with fairly simple structure.Further, as long as owing to making test section Part 100 engages with axle portion 220 and makes the end 121A of the second detection part 120 abut with framework 200, therefore, it is possible to fixed Easily assemble under the state of detection part 100 of position.

Further, owing between the first detection part main body 111 and the one end in axle portion 220, (the 3rd inner peripheral portion 111C is with outer Side minor diameter part 222B) and the other end between (the first inner peripheral portion 111A and outside large-diameter portion 222A) contact, therefore, it is possible to suppression Detection part 100 is relative to the swing in axle portion 220, it can be ensured that detection part 100 is relative to the stability in axle portion 220.Another Aspect, part (the second inner peripheral portion 111B between the first detection part main body 111 and the one end in axle portion 220 and the other end With outside minor diameter part 222B) do not contact and there is gap, even if therefore the diameter in axle portion 220 is somewhat when being screwed into tapping screw 91 Become big, it is also possible to absorb the change of its diameter, it can be ensured that detection part 100 is relative to the axle portion 220 i.e. positional precision of framework 2.

Further, in the inner peripheral surface in hole portion 221, the top ends in axle portion 220 comprise the 3rd inner peripheral portion 111C and outside path The scope that portion 222B the is contacted part (inner side large-diameter portion 221B) in interior opening edge side is than other part (inner side minor diameter part 221A) the most expanding, therefore when being screwed into tapping screw 91 to hole portion 221, particularly can suppress the 3rd inner peripheral portion 111C The diameter change of leading section that contact with outside minor diameter part 222B, axle portion 220.Thereby, it is possible to further ensure that detection part 100 relative to the positional precision of framework 2.
