Description
Technical field
Photosensitive drums and handle box that the utility model relates to driven unit, adopts this driven unit to make up.
Background technology
Electrophotographic image forming comprises duplicating machine, laser printer and similar devices.
A handle box is arranged in the electrophotographic image forming usually, and handle box can be mounted on the master component of electrophotographic image forming and from master component and dismantles.For example, by one is had photosensitive drums and integrally is assembled to the handle box for preparing in the box body as in developing apparatus, charging device and the cleaning device for the treatment of apparatus at least one.
Existing handle box comprises following kind: by fit over the first kind of handle box for preparing in the box with photosensitive drums with by the integral installation that developing apparatus, charging device and cleaning device are formed; By photosensitive drums and charging device integral installation are fitted over the second kind of handle box for preparing in the box; And by integral body assembling photosensitive drums and the third handle box of preparing by two processing units that charging device and cleaning device are formed.
User oneself can be mounted to the electrophotographic image forming master component with removably with above-mentioned handle box.Therefore, the user can carry out the maintenance of equipment, and need not to rely on the attendant of specialty, and then, improved the operability that the user safeguards electrophotographic image forming.In above-mentioned traditional handle box, it is as follows so that drive the photosensitive drums driving mechanism to be used for slave unit master component reception rotary driving force.
In the master component side, be provided with rotatable and a non-circular hole of reversing, rotatable driving force that is used to transmit motor reversed the central part that the hole is arranged on rotatable, be provided with a plurality of bights and have can with the xsect of rotatable unitary rotation.
In cartridge side, a non-circular projection of reversing is set, projection is arranged on one of them axial end portion of photosensitive drums, and has the xsect that is provided with a plurality of bights.When handle box was filled to the equipment master component, rotatable when rotating under the state that projection and hole are engaged with each other, rotatable rotary driving force was passed to photosensitive drums.As a result, the revolving force slave unit master component that is used to drive photosensitive drums is passed to photosensitive drums.Another kind of known mechanism drives photosensitive drums by the gear that is engaged to photosensitive drums, and then drives the handle box that photosensitive drums constitutes.Yet, in the conventional construction described in the U.S. Pat 5903803, when by moving handle box and handle box is mounted to master component or when master component is removed, need makes rotatable to move along horizontal direction along direction with rotatable axis approximate vertical.That is, need make rotatable to move horizontally by the opening and closing operation of master component lid.By the opening operation of described master component lid, separate with projection in the hole.On the other hand, by the shutoff operation of master component lid, move so that and protrusion engagement towards projection in the hole.Therefore, in traditional handle box, a kind of mechanism need be set on master component, it is used for moving rotatable by the opening and closing operation of master component lid along the rotation direction.In U.S. Pat 4829335 described structures, need not to move the driven wheel that is arranged at master component along its axis direction, described box just can be mounted to master component and tears open but from master component by moving along the direction that is approximately perpendicular to described axis.Yet in this structure, the driving connecting portion between master component and the handle box is the engaging piece between the gear, thereby is difficult to prevent the rotation unevenness of photosensitive drums.
U.S. Patent Application Publication instructions US2008/0152388A1 discloses another kind of handle box, and the improvement of its above-mentioned relatively handle box is that the driven unit that is positioned at an axial end portion of photosensitive drums is to adopt ball formula universal joint to drive connecting structure.This driving connecting structure exists easily to deviate from from driven unit, and particularly in the middle of transportation, this phenomenon more is prone to, and makes the afunction or the job insecurity of driven unit.
China utility model patent CN200920238326.2 provide a kind of drive assembly of photosensitive drum, comprises the gear that is tight with at photosensitive drums one end and axially adjust assembly, and this is axially adjusted assembly and has comprised the first motion sub-component, channel parts and central shaft parts; Described channel parts has spatially orthogonal upper hopper chute and gliding groove, and the described first motion sub-component forms the cooperation of relative slip with described upper hopper chute on first direction; Described central shaft parts and described gear have common axis, and it forms the cooperation of relative slip with described gliding groove on second direction; Described first direction and second direction all perpendicular to photosensitive drum shaft to.The described first motion sub-component comprises that stretching out the outer rotary driving force of described gear receives a head and an adjustment slide block, described rotary driving force receives head can be connected in described adjustment slide block rotatably around its axis, and being provided with one between described rotary driving force reception head and the adjustment slide block can be around the rotary spacing pin of described axis rotation.When handle box fell machine or taking-up, the rotary driving force in the above-mentioned drive assembly of photosensitive drum received stuck problem takes place between head and the imaging device driving head easily.Therefore, above-mentioned drive assembly of photosensitive drum still has further improved space.
