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.
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.
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.
In the above-described embodiment, make and detect projection 82 and move to the inboard direction of declivity, but the utility model is not limited thereto, for example can make and detect projection 82 and move up at right and left from the position of last oblique front side.Also can constitute bearing surface in addition is curved surface, and moving body is moving on the circular-arc guide rail of this curved surface.
In the above-described embodiment, utilize tooth bar/pinion structure that moving body 80 is moved, but the utility model is not limited thereto.For example, can shown in Figure 10 (a) and (b), in the end face of stirrer-driven gear 66, form axially outstanding projection 66A, and on moving body 800, form the fastening arm 801 that fastens with projection 66A from the position that rotation center departs from.At this moment, the projection 66A pushing mobile by the rotation of following stirrer-driven gear 66 fastens arm 801, thereby moving body 800 is being moved on the rectilinear direction of bearing surface 82A.
In the above-described embodiment, adopted a pair of guiding rail 67, but the utility model is not limited thereto, for example also can adopts groove, a guide rail as first guide portion as first guide portion.In addition, can not elongated slot 71 as second guide portion, and for example be that guiding detects guiding wall projection 82 and face bearing surface 82A opposition side.
In the above-described embodiment, the utility model is applied to laser printer 1, but the utility model is not limited thereto, also can be applied to other image processing systems, for example duplicating machine, compounding machine etc.
