Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As Fig. 1, Fig. 2, shown in Fig. 9 and Figure 10, image processing system 20 comprises the relative the first side wall in left and right 22 and the second sidewall 23, wherein the first side wall 22 comprises inwall 22a and the recess 22b that holds detection arm 21.
As shown in Fig. 2 and Fig. 6, cartridge 1 comprises the first side wall 13A and the second sidewall (not shown) and the rotatable developer roll 3 being supported between two side that 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 above by the input gear 2a being 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, in detection of gear 5, be provided with without toothed portion 5a, there are toothed portion 5b and pilot hole 5c, 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 shown in Figures 3 to 5, 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, on guidepost 6a, be provided with circumferential notch 6d and ladder platform 6b, 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 the circumferential notch 6d that detects projection 6 and prevents that detection projection 6 from coming off in the pilot hole 5c of detection of gear 5.
When cartridge 1 packs in the process of image processing system 20 along F direction, in the initial period, as shown in Fig. 7 to Fig. 8, when detection projection 6 contact images of cartridge 1 form the inwall 22a of device 20, owing to detecting the spigot surface 6c of 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 in R direction of the relative detection of gear 5 of developer roll 3 axial direction, and now spring 7 is in compressive state.
When cartridge 1 packs (as shown in Figure 9) after image processing system 20 completely into, it is protruding in L direction that detection projection 6 is being parallel to the relative detection of gear 5 of developer roll 3 axial direction under the effect of spring 7, 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 process along C direction from initial position as shown in Figure 9 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 has toothed portion 5b, 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 projection 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 receiving this cartridge 1 is new cartridge, when the second idle pulley 11 drives detection of gear 5 to be rotated further position as shown in figure 13, now detection of gear 5 is relative with the second idle pulley 11 without toothed portion 5a, power transmission is ended, detect projection 6 positions that stop at as shown in figure 13.
When cartridge 1 splits out from image processing system 20 along D direction (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 splitting 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 relative detection of gear 5 of protruding 6 Compress Spring 7, and cartridge 1 can split out easily from image processing system 20.
Because cartridge 1 is the process that packs image processing system 20 into or split out from image processing system 20, detect the inside indentation of the projection 6 relative detection of gear 5 of meeting, thereby be beneficial to packing into and splitting out of cartridge 1, when cartridge 1 packs into after image processing system 20 completely, 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 detecting projection 6 is rotated counterclockwise in process and can touches detection arm 21 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.
Finally it should be noted that: above embodiment only illustrates technical scheme of the present invention, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
