Embodiment

Being described in detail below in conjunction with the embodiment of accompanying drawing to the utility model handle box, should be appreciated that specific embodiment described below only for explaining the utility model, but and be not used in restriction the utility model.

As shown in Figure 2, the utility model handle box comprises: the bulging box 1 of rotary support photosensitive drums 6, and the Delevoping cartridge 2 of rotary support developer roll 5 Delevoping cartridge 2 is also provided with oppressed portion 2a, be arranged on the limit lid 3 of process cartridge frame body one side, and be arranged on the rotary unit 4 on limit lid 3.As shown in Figure 3, rotary unit 4 is arranged on limit lid 3, and can cover 3 rotations around limit.Selectively, rotary unit 4 also can be arranged on bulging box 1, as long as rotary unit 4 can rotate around stationary shaft, rotary unit 4 is preferably arranged on limit lid 3 by the present embodiment.

As shown in Figure 4, limit lid 3 is provided with locating ring 3b, it is set to the hollow ring protruded from lid inner side, limit; Anti-drop device 3d, can be set to have flexible barb, and the periphery around locating ring 3b is arranged, and can be set to one or more, for preventing rotary unit 4 slippage from limit lid 3; Groove 3a, be arranged on the top of limit lid 3, described groove has first end 3a1 and the second end 3a2 wherein, and first end 3a1 and the second end 3a2 is set to confined planes; Holding tank 3c, be arranged on the bottom of limit lid 3, have first end 3c1 and the second end 3c2, wherein said 3c1 and 3c2 is also set to confined planes.As shown in Figure 5, rotary unit 4 comprises: installation portion 4b, is set to hollow right cylinder, is rotatably installed on locating ring 3b; Power acceptance division 4c, is set to inclined-plane, has the first contact inclined-plane 4c1 and contacts inclined-plane 4c2 with second; Compel pushed section 4a.The installation portion 4b of this rotary unit in the present embodiment, power acceptance division 4c, compel pushed section 4a and be wholely set, it is also separable setting selectively.As shown in figures 2-6, after installation portion 4b in rotary unit 4 is mounted to the locating ring 3b of limit lid 3, and by anti-drop device 3d, rotary unit is limited on locating ring 3b, prevent it from slippage locating ring 3b, thus rotary unit 4 Absorbable organic halogens ground rotate around the axle center of locating ring 3b.Before handle box loads image processing system, Delevoping cartridge 2 is positioned at primary importance, and the power acceptance division 4c in rotary unit 4 is in the first end 3c1 of holding tank, and is limited by the confined planes in first end 3c1; Compel the first end 3a1 that pushed section 4a is positioned at groove, spacing by the confined planes of 3a1; Now, developer roll 5 and photosensitive drums 6 are in contact condition.

Below in conjunction with Fig. 7 to Fig. 9, the process that the developer roll 5 of specifically setting forth the Delevoping cartridge in the utility model handle box is separated with photosensitive drums 6 in drum box.

Imaging device includes separating member 10, and it can horizontally left direction M and level move in N direction to the right, separating member 10 is provided with teat 11, teat 11 is provided with arc surface 12; Separating member 10 has rotation center 14, and elastic component 13 is arranged on the side of separating member 10 away from rotation center 14, moves between precalculated position and compression position for making separating member 10.

When handle box is mounted in electronic imaging apparatus along H direction, now separating member 10 is also in predetermined primary importance, and arc surface 12 disposed thereon contacts with the first inclined-plane 4c1 of the power acceptance division 4c in rotary unit 4, when horizontally move further by left M direction for separating member 10, because power acceptance division 4c is subject to the restriction of confined planes, so its first inclined-plane 4c1 oppresses arc surface 12 and applies a component f straight down to it, after separating member 10 receives power f, elasticity of compression component 13, elastic component 13 will overcome elastic force and make separating member 10 rotate to advanced position along rotation center 14, when separating member 10 moves along the direction of level M left further, then will enter state as shown in Figure 8, teat 11 be separated contact site second inclined-plane 4c2 and engage, elastic component 13 recovers elastic force to precalculated position, then in electronic imaging apparatus, separating member 10 will horizontally move in right N direction, because of the teat 11 in separating member 10 be separated contact site second inclined-plane 4c2 and be engaged, separating member 10 is by applying level power F1 to the right to described separating member contact site 4c, thus the axle center around locating ring 3b is counterclockwise rotated by rotary unit 4, compel the oppressed portion 2a that pushed section 4a compels to push away in Delevoping cartridge 2, thus apply level power F2 left on Delevoping cartridge 2, Delevoping cartridge 2 is forced to rotate along counterclockwise S direction, when separating member 10 moves to the predetermined second place, Delevoping cartridge 2 and rotary unit 4 are in the second place, now compel the second end 4a2 that pushed section 4a is placed in groove, separating member contact site 4c is in the second end 4c2 of holding tank, developer roll 5 is separated predetermined gap e with photosensitive drums 6.

Compared with existing handle box, the handle box that the utility model provides, be provided with rotary unit 4, being separated of developer roll and light-sensitive roller is realized by the rotation of rotary unit 4, structure is simple, easy for installation, stable performance, avoids in prior art because separating member and power receiving member produce relative sliding and easily stuck technical matters.

Above embodiment only in order to the technical scheme of this utility model to be described, is not intended to limit; Although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
