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 shown in Figures 1 to 5, image processing system 20 comprises detection arm 21.Cartridge 1 comprises the first side wall 13A and the second sidewall (not shown) and the rotatable developer roll 14 being supported between two side that left and right is relative, powder storehouse 11 storage carbon dusts, on the first side wall 13A of cartridge 1, be provided with guide rail 12 and stop member 15, its middle guide 12 comprises domatic 12a, plane 12b and Caused by Sloping Surfaces 12c, by input gear 2, developer roll gear 3, powder feeding roller gear 5, idle pulley 6, the protecting cover 4 that the first side wall 13A that the gear train that puddle support gear 7 and detection of gear 8 forms is arranged on cartridge 1 went up and be equipped with arc notch 4a covers, wherein input gear 2 is duplicate gear with idle pulley 6, internal gear 2b while and the developer roll gear 3 of input gear 2, 5 engagements of powder feeding roller gear, the outer gear 6a engagement of its outer gear 2a and idle pulley 6, puddle support gear 7 meshes with internal gear 6b and the detection of gear 8 of idle pulley 6 simultaneously.In detection of gear 8, be provided with without toothed portion 8a, there are toothed portion 8b and pilot hole 8c, cartridge 1 also comprises the detection projection 9 coordinating with detection of gear 8, detect projection 9 and comprise the guidepost 9a coordinating with pilot hole 8c and the chute 9b coordinating with guide rail 12, spring 10 is socketed in and detects in projection 9 and the inwall 4b of its first end 10a butt protecting cover 4, and its second end 10b butt detects the end face of protruding 9 guidepost 9a.
At cartridge 1, pack into after image processing system 20, as shown in Fig. 6 A to Fig. 6 C, have toothed portion 8b and the puddle support gear 7 of detection of gear 8 mesh, detect projection 9 and be retracted within the position in the arc notch 4a of protecting cover 4 in (as shown in Figure 6 C), when starting image processing system 20, the driving force that the input gear 2 of cartridge 1 is accepted from image processing system 20, puddle support gear 7 turns clockwise and drives detection of gear 8 to be rotated counterclockwise, as shown in Fig. 7 A to Fig. 7 C, in the processes that detection projection 9 is rotated with detection of gear 8, its chute 9b moves to plane 12b along the upper domatic 12a of guide rail 12, therefore detecting projection 9 stretches out along being parallel to the arc notch 4a from protecting cover 4 in the axial direction of developer roll 14, the end face that now detects the guidepost 9a of projection 9 compels to push away the second end 10b of spring 10, therefore spring 10 is in compressive state, in the process of chute 9b rotational slide on the plane 12b of guide rail 12 that detects projection 9, detect the detection arm 21 of projection 9 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, along with detecting projection 9, be rotated further, as shown in Fig. 8 A to Fig. 8 C, the chute 9b that detects projection 9 moves to the Caused by Sloping Surfaces 12c of guide rail 12, spring 10 compels to push away the end face of the guidepost 9a that detects projection 9, cause detection projection 9 from the arc notch 4a of protecting cover 4, to be inwardly retracted within position as shown in Figure 8 c along being parallel to the axial direction of developer roll 14, now detection of gear 8 is relative with puddle support gear 7 without toothed portion 8a, power transmission is ended, detection projection 9 is blocked parts 15 and is limited in position as shown in Figure 8 B.
Because image processing system 20 is in the process of work, thereby the detection projection 9 of cartridge 1 is stretched out the detection arm 21 of touching image processing system 20 and produces an ON/OFF signal along being parallel to the relative detection of gear 8 of the axial direction of developer roll 14 from the arc notch 4a of protecting cover 4, the CPU of image processing system 20 is according to the ON/OFF signal receiving, can judge that this cartridge 1 is unworn, when detecting projection 9, touched after detection arm 21, detecting projection 9 again can be from the arc notch 4a of protecting cover 4 along being parallel to the inside indentation of the relative detection of gear 8 of the axial direction of developer roll 14, therefore cartridge 1 is before packing image processing system 20 into and splitting out from image processing system 20, detecting projection 9 is all that contracting is in the arc notch 4a of protecting cover 4, therefore being beneficial to cartridge 1 packs image processing system 20 into and splits out from image processing system 20, owing to only having projection of detecting 9, stretch out and indentation being parallel on developer roll 14 axial directions detection of gear 8 relatively, detection of gear 8 just drives and detects projection 9 rotations, therefore guaranteed that between detection of gear 8 and puddle support gear 7, engaged transmission is steady, 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.
