The process of mounting the process cartridge of the present invention will be described with reference to fig. 3 to 11:
As shown in fig. 3, in the case where the process cartridge is provided with the first guide portion 101, the second guide portion 102, the third guide portion 103, and the fourth guide portion 104, the procedure is as follows: when the process cartridge starts to be mounted in the image forming apparatus, the guide portion 103a at the front end of the third guide portion 103 is brought into contact with the first guide portion 201 on the image forming apparatus, and the surface of the guide portion 103a is brought into contact with the surface of the first guide portion 201 and moves along the first guide portion 201, so that the process cartridge is smoothly moved forward; with the movement of the process cartridge, the third guide 103 is in contact with the first guide 201, and then the first guide 101 is also in contact with the third guide 203 (fig. 4), since the first guide 101 is caught by the third guide 203 after contacting the third guide 203, the end of the first guide 101 of the process cartridge (the end far from the photosensitive drum and/or the developing roller driving force receiving end) cannot be moved forward any more, while the other end of the process cartridge (the end at the photosensitive drum and/or the developing roller driving force receiving end) can still be moved forward, and the third guide 103 moves along the first guide 201, so that the process cartridge 100 starts to perform the rotational movement;
As the process cartridge moves forward, the third guide 103 moves along the first guide 201, and under the cooperation of the third guide 103 and the first guide 201 and the blocking action of the third guide 203 on the first guide 101, the process cartridge continues to rotate during the forward movement until the first guide 101 avoids the third guide 203 (fig. 5), at this time, the second guide 102 is parallel to the first guide 201, the fourth guide is also parallel to the second guide 202, and the second guide 102 and the fourth guide move along the first guide 201 and the second guide 202, respectively, so that the process cartridge keeps moving obliquely forward; as the cartridge advances, the first contact protrusion 108 and the second contact protrusion 109 also contact the second trigger 204 and the first trigger 205, respectively, so that the cartridge can continue to move forward;
As shown in fig. 6, when the process cartridge 100 is moved obliquely forward until its forward end (the end at which the photosensitive drum and/or developing roller driving force receiving end is located) comes into contact with the first stopper 206 of the printer, the end at which the photosensitive drum and/or developing roller driving force receiving end of the process cartridge is located is blocked by the first stopper 206 from continuing the movement; in the case of the process cartridge having the fourth guide portion 104 on the top wall, the fourth guide portion moves to the end of the second guide portion 202 at this time, and when the fourth guide portion 104 is separated from the second guide portion 202, the process cartridge rotates about the first stopper 206 as a rotation point;
as shown in fig. 7, when the process cartridge is rotated until the rear end thereof contacts the second stopper 207, the process cartridge stops rotating and advancing, completing the mounting.
By providing the first and second slide guide mechanisms, during the mounting of the aforementioned process cartridge, since the driving force receiving head (driving force receiving member) is movable on a plane perpendicular to the rotational axis of the photosensitive drum (and/or developing roller) within a certain range, the driving force receiving member has a first position and a second position with respect to the photosensitive drum (and/or developing roller), the first position being a position where the rotational axis of the driving force receiving member coincides with the rotational axis of the photosensitive drum (and/or developing roller), and the second position being a position where the rotational axis of the driving force receiving member does not coincide with the rotational axis of the photosensitive drum (and/or developing roller). The driving force receiving assembly is located at the first position, for example, when a driving force receiving head in the driving force receiving assembly does not interfere with a driving head or other components on the image forming apparatus; when the driving force receiving head interferes with a driving head or other components on the image forming apparatus to hinder the mounting of the process cartridge, the driving force receiving head moves on a plane perpendicular to the rotational axis of the photosensitive drum (and/or the developing roller) under the action of the interference force, and the driving force receiving assembly is located at the second position, at which time the rotational axis of the driving force receiving assembly is parallel to but not coincident with the rotational axis of the photosensitive drum (and/or the developing roller), so that the related components can be avoided, i.e., after the process cartridge is not mounted or is mounted, the driving force receiving assembly is located at the first position, and the driving force receiving assembly is located at the second position during the mounting of the process cartridge. The return spring serves as a return mechanism by which the driving force receiving assembly can be returned from the second position to the first position so that the driving force receiving head of the driving force receiving assembly cooperates with the driving head of the image forming apparatus after the process cartridge is mounted in place.
The invention sets the first guiding part which plays the rotation center and the driving force receiving head on the top wall of the processing box shell, which can move along the plane perpendicular to the rotation of the photosensitive drum and/or the developing roller in a certain range, and the processing box can be smoothly installed in the image forming device in an inclined mode by correspondingly matching the first guiding part with the guiding part in the installation inlet position of the image forming device. In particular, by arranging the second guide portion and the third guide portion in a "shape" of a bent arrangement, the process cartridge can be further guided to be smoothly mounted in an inclined manner in the image forming apparatus.
Example two
As shown in fig. 12, the difference between the first embodiment and the first embodiment is that the first guide portion 101 and the third guide portion 103 are located at the front portion of the top wall s5, and neither the first guide portion 101 nor the third guide portion 103 exceeds the front wall s1 of the housing.
Of course, the technical concept of the present invention is not limited to the above-described embodiments, and many different embodiments can be obtained according to the concept of the present invention, for example, the inclination of the third guide portion, the second guide portion, and the fourth guide portion with respect to the driving force receiving end plane or the rotation axis of the photosensitive drum and/or the developing roller in which direction is to be inclined may be changed according to the position of the guide portion on the image forming apparatus and the direction in which the process cartridge is to be inclined; the first guide part, the third guide part and the fourth guide part can be continuous extending convex ribs, and a plurality of convex columns which are arranged at intervals can also replace the convex ribs; also, in the foregoing embodiments, the photosensitive drum may be replaced with the developing roller, or the photosensitive drum and the developing roller coexist, and such modifications and equivalent variations are intended to be included in the scope of the present invention.
