Detailed structure in the<main body case 〉
As shown in Figure 6, in main body case 2, be provided with drive unit 110, new product specification pick-up unit 120.Below this is carried out simple declaration.
The part of the installation Delevoping cartridge 28 in the main body case 2 is provided with: to the drive unit 110 of input gear 62 transmission of drive force of Delevoping cartridge 28; New product detects and the new product specification pick-up unit 120 of specification detection with carrying out.
Drive unit 110 is made of not shown a plurality of gears and drive motor.And in the time of in Delevoping cartridge 28 is installed to main body case 2, the gear of drive unit 110 sides and 62 engagements of input gear, thus arrive input gear 62 from the driving force of drive motor via each gear transmission.In drive unit 110, with input gear 62 meshed gears for example with the switching interlock of protecgulum 2A, and with respect to input gear 62 advance and retreat.
New product specification pick-up unit 120 mainly comprises as shown in Figure 7: optical sensor 121, detection arm 122, volute spring 123 and control device 124.
Optical sensor 121 is the sensors that are used to detect the swing of detection arm 122, in the light time that is received self-luminescent part 121A by light accepting part 121B, to control device 124 output prearranged signals.
Detection arm 122 comprises cylindrical portion 122A that rotatably is supported on the main body case 2 and shading arm 122B and the abutment arms 122C that extends to radial outside from cylindrical portion 122A, and it can be the center swing with cylindrical portion 122A that this detection arm 122 constitutes.In addition, volute spring 123 is installed in the appropriate location of the shading arm 122B of detection arm 122, thus detection arm 122 always by volute spring 123 to the neutral position application of force.And on this neutral position, the leading section 122D of shading arm 122B is configured between illuminating part 121A and the light accepting part 121B.On this external this neutral position, the leading section 122E of abutment arms 122C be configured in can with the position of detecting projection 82 (92) butts on, this detections projection is given prominence to from the outside surface of the Delevoping cartridge 28 (128) that is installed on main body case 2.
Control device 124 has following function: have or not swing according to the detection arm 122 that is detected by optical sensor 121, judge whether Delevoping cartridge 28 is new product; And turn back to the needed time till the initial position according to begin to be driven into detection arm 122 from drive unit 110, judge the specification of Delevoping cartridge 28.Specifically, this control device 124 is carried out known idle running action according to the signal that sends from the shutdown signal of the sensor of the closing motion that is used to detect protecgulum 2A or when connecting the power supply of laser printer 1.And whether this control device 124 judges whether to receive the ON signal from optical sensor 121 outputs, thereby is the judgement of new product according to by detecting projection 82 (92) pushing detection arm 122.This control device 124 in addition, be under the situation of the state that tilts from initial posture in detection arm 122, according to continuing the time of reception of the ON signal of output from optical sensor 121 (from the idle running action, to detection arm 122 revert to initial posture, time till being cut off from the ON signal of optical sensor 121), carry out specification and judge (for example be maximum image form number be the judgement of 3000 type or 6000 type).
Next the action of moving body 80,90 when Delevoping cartridge 28,128 is installed to main body case 2 is described.In the following description, the Delevoping cartridge 28 with moving body 80 is that maximum image formation number is 3000 a type, and the Delevoping cartridge 128 with moving body 90 is that maximum image formation number is 6000 a type.
When being installed to the Delevoping cartridge 28 of 3000 types of new product state in the main body case 2 as shown in Figure 6, shown in Fig. 8 (a), detect the bearing surface 82A of projection 82 and the bottom butt of detection arm 122.Thereby by detecting projection 82 pushing detection arm 122, the bottom of detection arm 122 is with detecting projection 82 (Delevoping cartridge 28) side shifting inwards.
And, when detection arm 122 is swung like this, to control device 124 output ON signals, be judged as new product by this control device 124 from optical sensor 121.Thereafter, when moving by the known idle running of control device 124 execution, shown in Fig. 8 (b), the driving force of drive unit 110 is delivered to moving body 80 via input gear 62, neutral gear 65 and stirrer-driven gear 66, moving body 80 along its bearing surface 82A linearity move.At this moment, the invariant position of the part R that the bearing surface 82A after moving preceding bearing surface 82A and moving is overlapping, detection arm 122 supported on this overlapping part R is still supported by bearing surface 82A.Therefore, the position of detection arm 122 is kept, and continues the above-mentioned ON signal of output to control device 124.
Thereafter shown in Fig. 8 (c), when bearing surface 82A broke away from from detection arm 122, bearing surface 82A was disengaged the support of detection arm 122, and detection arm 122 turns back to the neutral position under the effect of volute spring 123.At this moment, the shading arm 122B of detection arm 122 turns back to initial position, cover the light of self-luminescent part 121A, thereby optical sensor 121 becomes the OFF state, and the ON signal is ended to the transmission of control device 124.
Thereby, calculating time of reception from the ON of optical sensor 121 signal, control device 124 is judged as 3000 type according to this time of reception.
Relative with it, when being installed to the Delevoping cartridge 128 of 6000 types of new product state in the main body case 2, shown in Fig. 9 (a), similarly, detect the bottom of projection 92 pushing detection arm 122 during with 3000 types, be judged as new product by control device 124., carry out idle running action thereafter, when moving body 90 moves along bearing surface 92A, shown in Fig. 9 (b), (c), the time when detection arm 122 is longer than 3000 types by bearing surface 92A support.Therefore, shown in Fig. 9 (d), bearing surface 92A breaks away from from detection arm 122, and when optical sensor 121 became OFF, the time of reception of control device 124 when being longer than 3000 types was judged as 6000 type.
In addition for example when the Delevoping cartridge 28 of 3000 types shown in Fig. 8 (a) does not use, because of misoperation of users has been transmitted under the situation of wrong driving force a little to gear mechanism 61, also can be shown in Fig. 8 (a) and (b), moving body 80 is only mobile a little on the direction of the bearing surface 82A that detects projection 80.At this moment, the part R that bearing surface about the bearing surface 82A before moving and after moving 82 is overlapping, invariant position.Therefore, by will this overlapping part R be configured in can with the position of detection arm 122 butts on, detecting projection 82 when mobile a little, also part R can be maintained can with the position of detection arm 122 butts, can push detection arm 122 well by part R when Delevoping cartridge 28 is installed.
According to above content, can obtain following effect in the present embodiment.
Constitute to make and detect projection 82 mobile on the direction of bearing surface 82A, thereby can be with the bearing surface 82A before moving and the location dimension of the overlapping part R of the bearing surface 82A after moving be held in can with the position of detection arm 122 butts on, even therefore transmitting a little to gear mechanism 61 under the situation of wrong driving force, also can carry out new product well and detect because of misoperation of users.
Constitute to make and detect projection 82 mobile on the direction of bearing surface 82A, thereby only by the length according to specification change bearing surface 82A, and can change the time that detection arm 122 is maintained heeling condition according to specification.Therefore can realize well that the specification of being undertaken by the mistiming detects.
The bearing surface 82A of detection projection 82 forms plane, and moving body 80 can move on the rectilinear direction of bearing surface 82A, and is therefore simple in structure, can realize the miniaturization of Delevoping cartridge 28.Though for example by detection projection 82 is being rotated on the direction of a curve of its bearing surface 82A, also can detection arm 122 be supported on same position with the bearing surface 82A before and after moving, but detection projection 82 is rotated in the mode of toppling over from the box main body 60 side direction left and right directions outside, thereby can cause Delevoping cartridge 28 on left and right directions, to maximize.
Moving body 80 from the initial position shown in Fig. 8 (a) when the retreating position shown in Fig. 8 (c) moves, the direction of leaving to the cylindrical portion 122A from detection arm 122 (below) moves, therefore at bearing surface 82A from the moment that detection arm 122 breaks away from, detection arm 122 turns back to initial position quickly.Thereby can making bearing surface 82 break away from the back from detection arm 122, cover the error of the time till the light of optical sensor 121 fully to detection arm 122 very little.Therefore the time set till beginning from the idle running action to return to detection arm 122 can be the very short time (mistiming), for example making 3000 types is 0.5 second, and 6000 types are 1 second.In addition, make the moving body 80 shown in Fig. 8 (a) when the direction (top) of the cylindrical portion 122A of close detection arm 122 is mobile, after bearing surface 82A broke away from from detection arm 122, detection arm 122 turned back to initial position lentamente when being supported by the bight of the inboard bottom of detecting projection 82.Therefore, bearing surface 82A broke away from the back from detection arm 122 cover the error of the time till the light of optical sensor 121 fully to detection arm 122 bigger this moment, so producing the time set that must move till beginning to return to detection arm 122 from idle running is the possibility of long period (mistiming), for example 3000 types are 5 seconds, and 6000 types are 10 seconds.
By the elongated slot 71 of pair of guide rails 67 and above-mentioned lid 70, from the left and right sides and front and back supported on both sides moving body 80, moving body 80 is moved under stable posture.
In addition, the utility model is not limited to above-mentioned embodiment, and example can utilize like that in every way as shown below.
In the above-described embodiment, bearing surface 82A is face completely, but the utility model is not limited thereto, and for example can will have the face of a plurality of recesses as bearing surface 82A.For example the imaginary face that is formed by the leading section of each gear teeth portion of gear also can think to form on the whole the face of the recess of a plurality of V word shapes, therefore can be with this imaginary (leading section of each gear teeth) as bearing surface.Yet when constituting bearing surface by the leading section of a plurality of gear teeth, the leading section of gear teeth is when orientation is moved, and detection arm 122 can produce trickle vibration along each gear teeth, therefore preferably makes bearing surface be face completely shown in above-mentioned embodiment.
