Detailed Description
The present application is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
In the following description, the front and rear directions are defined as the loading direction of the process cartridge during the process of loading the process cartridge into the image forming apparatus 200, that is, the side that first enters the image forming apparatus 200 during the installation is the front, the opposite side that last enters the image forming apparatus 200 is the rear, and the front and rear directions are the Y direction shown in the drawing.
As shown in fig. 1 to 34, the present application provides an image forming apparatus 200 including a process cartridge detachably attached inside the image forming apparatus 200. As shown in fig. 3, a turning fulcrum abutment portion 203 may be provided in the image forming apparatus 200, and when the process cartridge contacts the turning fulcrum abutment portion 203, the forward linear movement of the process cartridge is hindered and the process cartridge is rotated, so that the process cartridge is obliquely mounted in the image forming apparatus, and specifically, the left-right direction of the process cartridge, i.e., the longitudinal direction of the housing of the process cartridge, can form an angle other than 90 degrees with the mounting direction of the process cartridge into the image forming apparatus before the process cartridge is rotated, i.e., the oblique mounting of the process cartridge is achieved. Further, the turning fulcrum abutment portion 203 may be provided on a top wall of a cartridge mounting position provided in the image forming apparatus 200. The image forming apparatus 200 may further be provided with a first stopper 206 and a second stopper 207, and the process cartridge is mounted in place when the first stopper 206 and the second stopper 207 contact the process cartridge.
Further, a turn guide abutting portion 201 may be further provided in the image forming apparatus 200 to guide the rotation of the process cartridge.
It is to be understood that the process cartridge may be inclined to the left side or to the right side, or may be rotated counterclockwise or clockwise when being loaded in the image forming apparatus 200. The embodiments provided in the present application are described in detail as being inclined to the left side. When the inclined plate inclines to the right side, the whole of the embodiments provided by the application only needs to be in mirror symmetry. Specifically, the process cartridge includes a casing 100 and a developing unit provided in the casing 100, and the developing unit may include a photosensitive drum and/or a developing roller. The axis a of the developing unit is disposed along the length direction of the casing 100, and a driving force receiving end (simply referred to as a driving force receiving end) of the developing unit is disposed on one end surface of the casing 100 in the length direction. An end surface perpendicular to the axis of the developing unit defining the driving force receiving end is a driving force receiving end plane.
Specifically, referring to fig. 1 and 2, the case 100 has outer surfaces, which may include a front wall s1, a rear wall s2, a left side wall s3, a right side wall s4, a top wall s5, and a bottom wall (not shown). The bottom wall is disposed opposite to the top wall s5, the front wall s1 is connected between the top wall s5 and the bottom wall, and the left side wall s3 and the right side wall s4 are respectively located on both sides of the housing 100 in the longitudinal direction.
Further, the present application provides a process cartridge including a casing 100, the casing 100 being provided with a first steering fulcrum portion 101, the first steering fulcrum portion 101 protruding with respect to an outer surface of the casing, the process cartridge being rotatable about the first steering fulcrum portion 101 as a fulcrum to mount the process cartridge in an inclined manner. Specifically, the first turning fulcrum portion 101 comes into contact with the turning fulcrum abutment portion 203 to form a first turning fulcrum at which forward linear movement (movement in the Y direction) of the process cartridge is hindered and oblique turning occurs. The first steering fulcrum portion 101 may be fixedly or movably connected to the housing 100.
Further, the first turning fulcrum portion is provided on a side away from the driving force receiving end of the process cartridge in the longitudinal direction of the process cartridge case.
Specifically, the right side wall s4 may be provided with a mounting guide surface Q, an end plane of the mounting guide surface Q being disposed obliquely (non-perpendicularly) with respect to the axis of the developing unit, and a guide rib protruding from the end plane may be disposed on the end plane of the mounting guide surface Q, an outer contour of the guide rib being parallel to the end plane. The mounting guide surface Q allows the process cartridge to be loaded into the image forming apparatus 200 in an inclined manner during the process cartridge mounting or dismounting.
Further, the first steering fulcrum portion 101 is located on one side of the center line of the casing in the front-rear direction and perpendicular to the longitudinal direction of the process cartridge, that is, the first steering fulcrum portion 101 is disposed near one end of the casing in the longitudinal direction, so that the linear forward movement of the end of the process cartridge where the first steering fulcrum portion 101 is disposed is hindered, and the linear forward movement of the end of the process cartridge where the first steering fulcrum portion 101 is not disposed is continued unhindered, thereby causing the process cartridge to tilt.
Further, as shown in fig. 1, 2 and 3, the projection of the first turning fulcrum portion 101 on the top wall s5 of the casing 100 may be a curve that extends in the longitudinal direction of the casing and that is convex on the side toward the front of the casing 100. Preferably, the front side of the first steering fulcrum 101 is a cambered surface or a spherical surface, so that the structure is simple and the steering is smooth.
Specifically, the first steering fulcrum portion 101 may be disposed on the top wall s5 and protrude from the surface of the top wall s5, the first steering fulcrum portion 101 is located at the front left of the top wall s5, and the front end of the first steering fulcrum portion 101 is a cambered surface or a spherical surface.
More specifically, the first steering fulcrum portion 101 may be a cylinder protruding from the top wall s5, and a rear portion of the cylinder may be provided with an obliquely extending reinforcing structure (an extending direction of the reinforcing structure forms an angle different from 90 degrees with the driving force receiving end plane a) to reinforce the structural strength of the first steering fulcrum portion 101, and the reinforcing structure may be an obliquely extending rib or a plurality of obliquely continuously spaced convex columns. The front side of the first pivot portion 101 preferably protrudes beyond the front wall s1 so that the process cartridge can be tilted at the initial stage of loading into the image forming apparatus 200. It will be appreciated that the front side of the first steering fulcrum portion 101 may also be located behind the front wall s1 (i.e., the front side of the first steering fulcrum portion 101 does not protrude beyond the front wall s1, as shown in fig. 8).
Further, referring to fig. 10, the projection of the first steering fulcrum portion 101 on the top wall s5 of the housing 100 is a straight line extending in the longitudinal direction of the housing 100. At this time, a curved surface or a corner structure contacting the straight line may be provided in the image forming apparatus 200. That is, the projections of the first turning support point portion 101 and the turning support point abutting portion 203 on the top wall s5, one of which is curved and the other of which is straight, form a dotted line to make contact.
Specifically, when the projection of the first steering fulcrum portion 101 on the top wall s5 of the housing 100 is a straight line, referring to fig. 10 to 16, the first steering fulcrum portion 101 may be provided as a stopper a 101. When the process cartridge is rotated obliquely, the stopper a101 mounted on the process cartridge is also rotated obliquely together with the process cartridge, and when the process cartridge is first tilted to the proper position, the stopper a101 is just away from the turning fulcrum abutment 203 provided on the image forming apparatus 200. Thereby enabling the process cartridge to move forward while maintaining the inclined state.
Further, the first steering fulcrum portion 101 may be rotatably connected to the housing 100. The axis of the first steering fulcrum portion 101 (e.g., the pin a103) extends in the longitudinal direction of the housing 100, the rear portion of the first steering fulcrum portion 101 abuts against the housing 100, and a turning space is provided between the front portion of the first steering fulcrum portion 101 and the housing 100.
Further, the first steering fulcrum portion may be provided with a return means, which may be an elastic member such as a return torsion spring a102, and the return torsion spring a102 may abut against at least a part of the first steering fulcrum portion 101.
When the first steering fulcrum portion 101 is pivotally coupled to the housing 100, referring to fig. 20 and 21, a detailed description will be given taking the stopper a101 as an example. It is to be understood that the first steering fulcrum portion 101 may have other configurations such as the above-described cylinder. Specifically, the stop post a101 is rotatably coupled to the housing 100 by a pin a103, and the stop post a101 is provided with a return torsion spring a 102. The stopper a101 is fixed to the housing 100 by a pin a103, and the rear face of the stopper a101 abuts against the housing 100, so that the stopper a101 cannot rotate backward. While the front of the stop post a101 is not constrained, the stop post a101 can be rotated forward, i.e., about the direction shown in fig. 23.
Referring to fig. 17 and 18, the purpose of the forward rotation of the stopper a101 is to facilitate the detachment of the process cartridge, i.e., the removal of the process cartridge from the image forming apparatus 200, the stopper a101 can be rotated forward to avoid the fulcrum abutment 203 provided on the image forming apparatus 200, so that the process cartridge can be smoothly removed. That is, when the process cartridge is moved backward and taken out, the turning fulcrum abutment portion 203 contacts the stopper post a101 and rotates the stopper post a101 forward, and after the stopper post a101 which the turning fulcrum abutment portion 203 has passed over, the process cartridge can be smoothly detached while the stopper post a101 is returned to the original position by the return torsion spring a 102.
Further, as shown in fig. 1, 2 and 3, the casing 100 may further include a first steering guide 103, and the first steering guide 103 and the first steering fulcrum 101 are respectively located on both sides of a center line of the process cartridge in the front-rear direction, so that a large torque is generated with a small force when the process cartridge is rotated, and the first steering fulcrum 101 or the first steering guide 103 is prevented from being damaged.
Specifically, the distance from the first steering fulcrum portion 101 to the driving force receiving end plane is greater than one-half the length of the developing unit (or greater than one-half the length of the casing of the process cartridge), and the distance from the first steering guide portion 103 to the driving force receiving end plane is less than one-half the length of the developing unit.
