Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, Fig. 2, Fig. 9 and shown in Figure 10, image processing system 20 comprise the relative the first side wall in left and right 22 and the second sidewall 23, and wherein the first side wall 22 comprises inwall 22a and the recess 22b that holds detection arm 21.
as Fig. 2 and shown in Figure 6, cartridge 1 comprises the first side wall 13A and the second sidewall (not shown) and the rotatable developer roll 3 that is supported between the two side that the left and right is relative, the end of developer roll 3 is socketed with the electrode 4 of being made by conductive material, wherein carbon dusts are stored in powder storehouse 12, gear train is arranged on the first side wall 13A of cartridge upward by the input gear 2a that is arranged on driving head 2, developer roll gear 14, powder feeding roller gear 15, the first idle pulley 9, puddle support gear 10, the second idle pulley 11 and detection of gear 5 form, be provided with on detection of gear 5 without toothed portion 5a, toothed portion 5b and pilot hole 5c are arranged, wherein input gear 2a simultaneously and developer roll gear 14, powder feeding roller gear 15 and the first idle pulley 9 engagements, the first idle pulley 9 and the second idle pulley 11 are the outer little duplicate gear of imperial palace of diameter, the outer gear 9a of the first idle pulley 9 and input gear 2a engagement, its internal gear 9b and 10 engagements of puddle support gear, the internal gear 11b of the second idle pulley 11 and 10 engagements of puddle support gear, its outer gear 11a and detection of gear 5 engagements, as extremely shown in Figure 5 in Fig. 3, wherein cartridge 1 also comprises and detects projection 6 springs that coordinate 7 and jump ring 8, wherein detect the spigot surface 6c that projection 6 comprises guidepost 6a and circular arc, be provided with circumferential notch 6d and ladder platform 6b on guidepost 6a, the guidepost 6a that detects projection 6 coordinates with the pilot hole 5c of detection of gear 5, spring 7 is arranged in the pilot hole 5c of detection of gear 5 and is socketed on the guidepost 6a that detects projection 6, one end of spring 7 and the ladder platform 6b butt that detects projection 6, jump ring 8 is stuck in and prevents from detecting projection 6 in the circumferential notch 6d that detects projection 6 and come off in the pilot hole 5c of detection of gear 5.
In the process of image processing system 20 of packing into along the F direction when cartridge 1, in the initial period, as extremely shown in Figure 8 in Fig. 7, when detection projection 6 contact images of cartridge 1 form the inwall 22a of device 20, due to the spigot surface 6c that detects projection 6 and the inwall 22a Interference contact of image processing system 20, therefore the inwall 22a of image processing system 20 compels to push away and detects projection 6 along being parallel to the inwardly indentation on the R direction of the developer roll 3 relative detection of gear 5 of axial direction, and this moment, spring 7 was in compressive state.
after cartridge 1 is packed image processing system 20 fully into (as shown in Figure 9), detect projection 6 to be parallel to the developer roll 3 relative detection of gear 5 of axial direction under the effect of spring 7 protruding on the L direction, detecting projection 6 enters in the recess 22b that image processing system 20 holds detection arm 21, and detect projection 6 rotates to final position as shown in figure 10 along the C direction from as shown in Figure 9 initial position process can touching image processing system 20 detection arm 21, when starting image processing system 20, the driving head 2 of cartridge 1 is accepted the driving force of image processing system 20 and is transferred a driving force to detection of gear 5, because detection of gear 5 comprises without toothed portion 5a and toothed portion 5b is arranged, therefore the initial period as shown in figure 11, thereby the second idle pulley 11 drives 6 rotations of detection projection with the toothed portion 5b engagement that has of detection of gear 5, when detecting protruding 6 positions that move to as shown in figure 12, detect the detection arm 21 of projection 6 touching image processing systems 20 and produce an ON-OFF signal, thereby the CPU of image processing system 20 can judge that according to the ON-OFF signal that receives this cartridge 1 is new cartridge, when driving detection of gear 5, the second idle pulley 11 is rotated further as shown in figure 13 position, detection of gear 5 is relative with the second idle pulley 11 without toothed portion 5a at this moment, power transmission is ended, detect protruding 6 positions that stop at as shown in figure 13.
When cartridge 1 splits out 20 along the D direction from image processing system (as shown in figure 10), cartridge 1 detects the inwall 22a of the spigot surface 6c meeting Interference contact image processing system 20 of projection 6 in the process that splits out, therefore the inwall 22a of image processing system 20 compels to push away and detects the inwardly retraction on the axial direction that is parallel to developer roll 3 of the protruding 6 relative detection of gear 5 of Compress Spring 7, and cartridge 1 can split out from image processing system 20 easily.
because cartridge 1 is being packed image processing system 20 or from the process that image processing system 20 splits out into, detect the projection 6 inside indentations of the relative detection of gear 5 of meeting, thereby be beneficial to packing into and splitting out of cartridge 1, after cartridge 1 is packed image processing system 20 fully into, detect that projection 6 is can relative detection of gear 5 protruding to enter in the recess 22b that image processing system 20 holds detection arm 21, therefore detect projection 6 and be rotated counterclockwise meeting touching detection arm 21 in process with detection of gear 5, thereby the CPU of image processing system 20 receives an ON/OFF signal, can judge that this cartridge 1 is unworn.Because detection of gear 5 is not the protruding or inside indentation of the first side wall 13A of relative cartridge 1, therefore do not affect the steady engaged transmission between detection of gear 5 and the second idle pulley 11, guaranteed the print quality of cartridge 1.
It should be noted that at last: above embodiment only illustrates the technical solution of the utility model, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
