The detailed structure of＜Delevoping cartridge 〉
Next detailed structure as the Delevoping cartridge 28 of characteristic of the present utility model is described.
As Fig. 2 (a) and (b), Delevoping cartridge 28 also has box main body 60 and lid 70 as an example of framework except having above-mentioned developer roll 31 grades.Lid 70 releasably is installed on the left surface of box main body 60, between box main body 60 and lid 70, is provided with shown in Fig. 2 (a): gear mechanism 61 is used for to transmission of drive force such as developer rolls 31; Rotary body 80 as an example of service portion; With the mistiming adjusting mechanism, rotary body 80 additional period differences are transmitted driving force from gear mechanism 61.
As shown in Figure 3, rotary body 80 comprises: fastening axis 81 cylindraceous; The wrist 82 that extends to radial outside from the left end of fastening axis 81; The detection projection 83 as an example of service portion of extending to left (the left and right directions outside) from the front end of wrist 82; With from the outer peripheral face of fastening axis 81 to cord support portion 84 that radial outside (with outside 82 different directions) extends.This rotary body 80 rotatably fastens with the not shown support axial region that is formed on the box main body 60 by its fastening axis 81, thereby its detection projection 83 can move on the circular-arc track that with fastening axis 81 is the center.
Detect projection 83 and be connected with fastening axis 81, thereby be configured in from the position that the rotation center of rotary body 80 departs from via wrist 82.And this detects projection 83 as Fig. 2 (b) shown in, under the state of having assembled Delevoping cartridge 28, give prominence to foreign side from the peristome 71 of lid 70, thereby can with detection arm 122 butts described later.
In addition, the second support portion 84B is formed on respect to the first support portion 84A on the position that the direction of principal axis and the circumferencial direction of fastening axis 81 departs from a little, thereby the undercutting can prevent that rotary body 80 is shaped the time makes rotary body 80 well from mould separating.In addition, outstanding by the second support portion 84B is compared with the first support portion 84A to radial outside, can be with the guide utilization of the second support portion 84B as cord 91.
By the such formation first support portion 84A and the second support portion 84B, between the first support portion 84A and the second support portion 84B, along the holding tank 84C that radially is formed for clamping aftermentioned cord 91.In addition, this holding tank 84C is the groove of radial outside and direction of principal axis both-side opening, the peristome 84D of its radial outside by rotary body 80 rotation and gradually near (towards) cord 91.Specifically, this cord support portion 84 is formed on the precalculated position on the circumferencial direction of fastening axis 81, so that when rotary body 80 moves to the final position (with reference to Fig. 8), it is substantially parallel with holding tank 84C to open the cord of establishing 91 between rotary body 80 and aftermentioned holding plate 92 (being the first pin P1 in detail).
But cord 91 is elongated parts roughly cylindraceous of the relaxation that formed by cloth, fiber crops, man-made fiber etc., and the one end is clamped among the holding tank 84C of rotary body 80, and the other end is fixed on the winding reel 93.This cord is under the situation of new product state at Delevoping cartridge 28, between rotary body and winding reel 93 for lax state and remain on the holding plate 92.
In addition as shown in Figure 3, a pair of first pin P1, the P1 is set between holding plate 92 and rotary body 80, and a pair of second pin P2, the P2 is set between holding plate 92 and winding reel 93.And cord 91 is respectively through between a pair of first pin P1, the P1 and between a pair of second pin P2, the P2.Thereby cord 91 when becoming the state that stretches from holding plate 92 disengagings, is supported by the first pin P1 and the second pin P2 shown in Fig. 4 (b).Under the state that cord 91 stretches like this, rotary body 80 rotates to the final position of Fig. 4 (b) from the initial position of Fig. 4 (a).And, when rotary body 80 rotates to the final position, the position 91A of rotary body 80 sides of cord 91 is maintained the posture substantially parallel with the holding tank 84C of rotary body 80 between the first pin P1 and rotary body 80, therefore after moving along holding tank 84C, the peristome 84D from the radial outside of holding tank 84C pulls out easily.
Shown in Fig. 2 (b), on lid 70, be formed with and be used to peristome 71 that above-mentioned detection projection 83 is exposed to the outside.Peristome 71 is the circular-arc groove at center for the rotation center with rotary body 80, and at least one side of its upper edge and lower edge portion fastens with the detection projection 83 of predetermined fastening power (friction force) with rotary body 80.And should fastening power be set less than the fastening power of the holding tank 84C of cord 91 and rotary body 80, thus from cord 91 when rotary body 80 transmission of drive force, rotary body 80 is to have offset the driving force rotation after the fastening power that detects projection 83 and peristome 71.In addition, this fastening power is set to the fastening power of following degree: Delevoping cartridge 28 is being installed under the situation of main body case 2, when detecting projection 83 with aftermentioned detection arm 122 (with reference to Fig. 6) butt, the acting force that opposing is subjected to from detection arm 122 detects projection 83 and can make detection arm 122 swings.
In addition, on lid 70, be formed with and be used to make above-mentioned first pin P1, the P1 and second pin P2, the P2 to the outstanding bleed hole 72,72 in outside.Thereby shown in Fig. 2 (c), till relying on the position of base end side to front end than first pin P1, P1 (or second pin P2, P2), can make lid 70 near box main body 60, therefore can prevent that cord 91 breaks away from from the front end of first pin P1, the P1 (or second pin P2, P2) by lid 70.
In addition, as shown in Figure 5, 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.In addition in the present embodiment, the Delevoping cartridge of new product (using) is also not to importing the Delevoping cartridge that gear 62 applies driving force, do not drive developer roll 31.In addition, the Delevoping cartridge of old product (using) is meant to importing the Delevoping cartridge that gear 62 applies driving force, driven developer roll 31.
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 6: optical sensor 121, detection arm 122 and volute spring 123 and control device 124.
Next the action of time difference regulating mechanism 90 when Delevoping cartridge 28 is installed to main body case 2 is described.
When as shown in Figure 5 the Delevoping cartridge 28 of new product being installed in the main body case 2, shown in Fig. 7 (a), the detection projection 83 of rotary body 80 and bottom (the leading section 122E of the abutment arms 122C) butt of detection arm 122.At this moment, detect projection 83 and supported with predetermined friction force by peristome 71 (with reference to Fig. 2 (b)), therefore detect projection 83 pushing detection arm 122 by this, the bottom of detection arm 122 is with detecting projection 83 (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 being moved by the known idle running of control device 124 execution, shown in Fig. 7 (b), the driving force of drive unit 110 is delivered to winding reel 93 via input gear 62, neutral gear 65 and stirrer-driven gear 66, and winding reel 93 turns clockwise.When winding reel 93 rotated like this, cord 91 was by winding reel 93 drawings, thereby the slack that is bonded in the cord 91 on the holding plate 92 leaves successively from winding reel 93 sides on the holding plate 92.And become to the slack of cord 91 till the state of stretching during, cord 91 moves with respect to rotary body 80.Thereby become to the slack of cord 91 stretching the state position during, it is motionless to detect projection 83, so detection arm 122 also maintains on its position, continues the above-mentioned ON signal of output to control device 124.
And shown in Fig. 7 (c), when the slack of cord 91 became the state of stretching, by the cord support portion 84 of these cord 91 drawing rotary bodies 80, thereby rotary body 80 moved integratedly with cord 91, and opposing turns clockwise with the friction force of peristome 71.Thereby the fastening of the bottom of detection arm 122 and detection projection 83 is disengaged, 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, come the light of self-luminescent part 121A to be covered, 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 carries out specification according to this time of reception and judges.This time of reception for example can change by the slack (length of slack) according to specification appropriate change cord 91 in addition.In addition, if cord 91 is not set but on rotary body 80 the formative gear tooth, and this gear teeth is meshed via the gear and the stirrer-driven gear 66 of predetermined quantity, by adopting this structure detection projection 83 to be moved with the idle running action, therefore use the structure (having cord 91) of said structure and present embodiment according to specification respectively, can make the bigger mistiming.
And, when rotary body 80 rotates to position shown in Fig. 8 (a), stop by terminal butt with peristome 71.At this moment, the rotation of the peristome 84D accompanying rotation body 80 of the holding tank 84C of rotary body 80 and gradually near cord 91, finally between a pair of first pin P1, the P1.At this moment, continue by winding reel 93 coiling cords 91.Therefore cord 91 opposings are moved along holding tank 84C with the fastening power of the holding tank 84C of static rotary body 80, shown in Fig. 8 (b), break away from from holding tank 84C.Thereafter, cord 91 is winding on the winding reel 93 shown in Fig. 8 (c).
According to above content, can obtain following effect in the present embodiment.
Connect rotary body 80 and stirrer-driven gear 66 (winding reel 93) by lax cord 91, and make and detect projection 83 with predetermined friction force and peristome 71 fastenings, therefore till stretching to cord 91 during, stirrer-driven gear 66 is with respect to rotary body 80 rotations.Therefore, for example under the new product state, even because of the gear (for example be exposed to outside input gear 62) of misoperation of users to gear mechanism transmitted under the situation of wrong driving force, also can suppress to detect moving of projection 83, detection projection 83 is maintained on the initial position.
The length of the slack by appropriate change cord 91, can change idle running action beginning back to the mistiming of detecting till projection 83 begins to move according to specification, therefore can suppress the moving range that detects projection 83 less, can realize the miniaturization of Delevoping cartridge 28.In addition, by must be longer with the length setting of the slack of cord 91, can detect projection 83 and move stirrer-driven gear 66 (transmission gear) being revolved turn around to make after above, therefore can increase from the idle running action and begin to the mistiming of detecting till projection 83 begins to move.
With on holding plate 92, the bond slack of cord 91 of strippable cementing agent, therefore with for example the slack of cord 91 is filled in the structure that keeps in the casing and compares, can suppress cord 91 tangle ups, detection projection 83 is moved.
The peristome 84D of the radial outside of the holding tank 84C of rotary body 80, therefore can easily pull out cord 91 along holding tank 84C gradually near cord 91 by the rotation of rotary body 80.And then, the peristome 84D of final holding tank 84C is towards between a pair of first pin P1, the P1, thereby the cord 91 that stretches between first pin P1, the P1 and rotary body 80 is substantially parallel with holding tank 84C, therefore cord 91 can be pulled out easily and effectively along holding tank 84C.
In addition, the utility model is not limited to above-mentioned embodiment, can be by the variety of way utilization of following example.
