Embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among 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.

The first embodiment:

As shown in Figure 1: cartridge 1 comprises powder storehouse 2 storage carbon dusts, powder feeding roll shaft 5a, developer roll 6 is rotatable to be supported by the two side in powder storehouse 2, powder outlet cutter 4 contacts with the outline of developer roll 6, limit the thickness of developer roll 6 surperficial carbon dusts, comprise also that simultaneously jump ring 9 is fixed on electrode 3 on the development roll shaft 6a.Extremely shown in Figure 9 such as Fig. 2: current-carrying plate 7 comprises two hole 7a, 7b respectively with development roll shaft 6a, powder feeding roll shaft 5a cooperates, wherein current-carrying plate 7 is to be made by conductive material, torsion spring 8 is socketed in the groove that two protruding 7c that the upper and first end 8a of development roll shaft 6a is connected to current-carrying plate 7 consist of, the second end 8b is connected in the groove that two protruding 3d of electrode 3 consist of, electrode 3 comprises that hole 3a cooperates with development roll shaft 6a, contact 3b contacts with the input electrode in the printer, also comprise arc-shaped protrusions 3c, electrode 3 is made by conductive material, and jump ring 9 is fixed on development roll shaft 6a end and prevents that electrode 3 from coming off from development roll shaft 6a.

As shown in figure 14, drum assembly 12 comprises sidewall 13, and photo-sensitive cell 14, cartridge 1 are packed into after the bulging assembly 12, and developer roll 6 is with photo-sensitive cell 14 contacts, so photo-sensitive cell 14 surfaces form the carbon dust images.

As shown in Figure 2 to Figure 3: in cartridge 1 is packed the process of bulging assembly 12 into, because the arc-shaped protrusions 3c of electrode 3 contacts with the sidewall 13 of drum assembly 12, therefore the sidewall 13 of drum assembly 12 can apply a urgent thrust that makes progress to the arc-shaped protrusions 3c of electrode 3, therefore electrode 3 can turn clockwise under the effect of compeling thrust, rotate to position as shown in Figure 2 from as shown in Figure 4 position, in the process that electrode 3 turns clockwise, its protruding 3d can compel to push away the second end 8b of torsion spring 8, therefore in cartridge 1 is packed the process of bulging assembly 12 into, the second end 8b of torsion spring 8 is compressed to position as shown in Figure 3 from as shown in Figure 5 position.After cartridge 1 is packed bulging assembly 12 into, with the assembly of cartridge 1 and drum assembly 12 printer of packing into, the contact 3b of electrode 3 is connected with input electrode conducting in the printer, so voltage is sent to current-carrying plate 7 through development roll shaft 6a, thereby current-carrying plate 7 is sent to voltage on the powder feeding roll shaft 5a.The contact 3b of electrode 3 more near the input electrode in the printer, therefore guarantees that the contact 3b of electrode 3 is with the abundant conducting of the input electrode in the printer because the contact 3b of electrode 3 turns clockwise under the acting force of the sidewall 13 of drum assembly 12.

Extremely shown in Figure 5 such as Fig. 4: cartridge 1 is after 12 dismountings of drum assembly, because the arc-shaped protrusions 3c of electrode 3 no longer is subject to the urgent thrust that the sidewall 13 of drum assembly 12 applies, therefore the second end 8b of torsion spring 8 no longer is subject to the urgent thrust that two protruding 3d of electrode 3 apply, therefore the second end 8b of torsion spring 8 begins to recover deformation, from as shown in Figure 3 location restore to as shown in Figure 5 position, the second end 8b of torsion spring 8 compels to push away two protruding 3d of electrode 3 so that electrode 3 rotates to as shown in Figure 4 position from as shown in Figure 2 inverse position hour hands in recovering the process of deformation.

The second embodiment:

Extremely shown in Figure 11 such as Figure 10: current-carrying plate 10 comprises

hole

10a, 10b cooperates with development roll shaft 6a. powder feeding roll shaft 5a respectively, comprise also that simultaneously arc groove 10c cooperates with the protruding 11d of electrode 11, electrode 11 comprises that hole 11a is socketed on the development roll shaft 6a, so that the protruding 11d of electrode 11 can be to rotate in the arc groove 10c of the center of circle at current-carrying plate 10 around development roll shaft 6a, the contact 11b of electrode 11 contacts with the input electrode in the printer, and jump ring 9 is fixed on development roll shaft 6a end with electrode 11 and prevents that it from coming off.

Cartridge is in the process of bulging assembly 12 of packing into, because the arc-shaped protrusions 11c of electrode 11 contacts with the sidewall 13 of drum assembly 12, and be subject to sidewall 13 and apply upwards urgent thrust, so that the protruding 11d of electrode 11 is rotated clockwise to the position of 10c1 in the arc groove 10c of current-carrying plate 10 take development roll shaft 6a as the center of circle, therefore electrode 11 is rotated clockwise to position as shown in figure 12 from as shown in figure 13 position, cartridge and the assembly of drum assembly 12 are packed into behind the printer, the contact 11b of the cartridge electrode 11 of this moment under the effect of compeling thrust with printer in the abundant conducting of input electrode.

Cartridge is from the process of drum assembly 12 dismountings, because the arc-shaped protrusions 11c of electrode 11 no longer is subject to the urgent thrust that the sidewall 13 of drum assembly 12 applies, therefore under the Action of Gravity Field of electrode 11 self, so that the protruding 11d of electrode 11 is rotated counterclockwise the position of 10c2 in the arc groove 10c of current-carrying plate 10 take development roll shaft 6a as the center of circle, so electrode 11 rotates to as shown in figure 13 position from as shown in figure 12 inverse position hour hands.

It should be noted that at last: above embodiment only illustrates the technical solution of the utility model, is not intended to limit; For example among the first embodiment, the elastomeric element between electrode 3 and the current-carrying plate 7 is not limited only to torsion spring, can also be spring or extension spring, rotates to the second place so that cartridge is realized electrode 3 in the process of bulging assembly 12 of packing into from primary importance.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 made amendment 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.
