Detailed Description
The invention will be explained in the following with reference to the drawings and examples, which are provided for illustration only and are not intended to limit the invention.
The first embodiment is as follows:
in this embodiment, the rotational force applying member is axially retractable along the rotational axis thereof and also is swingable relative to the rotational axis thereof; and the rotational force receiving member does not telescope nor swing.
As shown in fig. 1, the image forming apparatus is provided with a rotational force applying member 101 and a spring 102; the spring 102 may provide an elastic restoring force to the rotational force applying member 101 so that it can be restored after being extended or swung. The process cartridge 7 is provided with the rotating member 71 and the rotational force receiving member 201; the rotational force receiving member 201 is provided at an axial end portion of the process cartridge (one end of the rotating member 71), and can supply the rotational force received from the rotational force applying member 101 to the rotating member 71 to rotate on the process cartridge.
As can be seen from fig. 1 and 2, the process cartridge 7 is mounted to the image forming apparatus in the axial direction of the rotary member 71 (the direction of arrow X is illustrated); the rotational force receiving member 201 provided at the axial end portion of the process cartridge engages with and receives the rotational force from the rotational force applying member 101 on the image forming apparatus.
As shown in fig. 3, the rotational force applying member 101 is further provided with a plurality of grooves 11, and the grooves 11 are symmetrically provided on the circumference of the rotational force applying member 101. The rotational force receiving member 201 is provided with an engaging portion 21, an elastic member 22 and a positioning member 23; the elastic elements 22 are arranged on the same side of at least one of the engagement portions 21, while the positioning elements 23 are arranged on the corresponding side (with respect to the axis X2) of the engagement portion 21. The engaging portion 21 is provided in plural in number smaller than the number of the grooves 11. The positioning element 23 is provided with a top surface 231 and a bevel surface 232.
The preferred embodiment of the present invention is that the engaging part 21, the positioning member 23 are symmetrically provided on the inner circumference of the rotational force receiving member 201, and the engaging part 21 is provided at a position corresponding to the position of the recess 11.
The present embodiment is described by taking as an example the case where three grooves are provided on the rotational force applying member 101, and the grooves 11 are symmetrically provided on the rotational force applying member 101, that is, the three grooves 11 are provided at 120 ° with respect to each other. At this time, when the engaging portions 21 on the rotational force receiving member 201 are provided in two; two engaging parts 21 are provided on the inner circumference of the rotational force receiving member 201, and the two engaging parts 21 are provided at 120 ° intervals therebetween; the positioning element 23 is arranged as one and on the corresponding side of both engagement portions 21, i.e. the positioning element 23 is arranged at a position 120 ° apart from both engagement portions, as shown in fig. 3 a. When the engaging portion 21 is provided as one and the positioning members 23 are provided as two, as shown in fig. 3b, the two positioning members 23 are provided symmetrically with respect to the one engaging portion 21 on the circumference, and are spaced apart by 120 °.
Fig. 3-6b are schematic views showing the engagement portion 21 on the rotational force receiving member 201 aligned with the recess 11 on the rotational force applying member 101 when the rotational force receiving member 201 approaches and abuts the rotational force applying member 101.
As shown in fig. 3, when the rotational force receiving member 201 is not abutted with the rotational force applying member 101, the axis X1 of the rotational force applying member 101 is coaxial or parallel with the axis X2 of the rotational force receiving member 201. The present embodiment is described by taking X1 and X2 as coaxial examples.
As shown in fig. 4, when the rotational force receiving member 201 approaches and contacts the rotational force applying member 101 in the illustrated X direction, the rotational force 101 is inserted into the inside of the rotational force receiving member 201 and abuts the elastic member 22, and the elastic member 22 swings the rotational force applying member 101 upward, so that the axis X1 of the rotational force applying member 101 is deviated from the axis X2 of the rotational force receiving member 201, and an angle a is formed between X1 and X2.
As shown in fig. 5, when the rotational force receiving member 201 continues to move in the X direction, the recess 11 of the rotational force applying member 101 at the lower end shown in the drawing comes close to and contacts the engaging portion 21 on the rotational force receiving member 201, at which time the upper end of the rotational force applying member 101 abuts the inclined surface 232 on the positioning member 23, and the rotational force applying member 101 moves along the inclined surface 232 to thereby bring the axis X1 of the rotational force applying member 101 close to the axis X2 close to the rotational force receiving member 201, so that the included angle a becomes smaller.
When the rotational force receiving member 201 continues to move in the direction X, the inclined surface 232 causes the recess 11 of the rotational force applying member 101 to approach and engage with the engaging portion 21, and finally, the state shown in fig. 6a is reached, at which the engaging portion 21 is completely engaged with the recess 11, and the included angle a further becomes smaller.
As shown in fig. 6b, when the rotational force receiving member 201 continues to move in the X direction and the upper end of the rotational force applying member 101 moves along the inclined surface 232 for a certain distance, the upper end of the rotational force applying member 101 abuts against the top surface 231 of the positioning member 23, and the top surface 231 provides a positioning function for the rotational force applying member 101, so that the engaging portion 21 does not allow the recess 11 to be disengaged from the engaging portion 21 while engaging with the recess 11 and transmitting the rotational force. At this time, the rotational force receiving member 201 can receive the rotational force from the rotational force applying member 101 and transmit it to the rotary member 71, the axis X1 coincides with the axis X2, and the process cartridge 7 can be started to operate.
When the process cartridge 7 is taken out of the image forming apparatus, the rotational force receiving member 201 is moved in the direction opposite to the direction X shown in FIG. 6b by the process cartridge, and the positional relationship between the engaging portion 21 and the recess 11 is moved from the state shown in FIG. 6b to the state shown in FIG. 6a, at which the rotational force applying member 101 is disengaged from the top surface 231. When the rotational force receiving member continues to move in the direction opposite to the X direction, the recess 11 abuts against the inclined surface 211 on the engaging portion 21, and the inclined surface 211 can swing the rotational force applying member 101 upward, thereby swinging the rotational force applying member 101 to the state shown in fig. 5; then, the state shown in fig. 4 is moved, in which the engaging portion 21 is disengaged from the groove 11, and the elastic member 22 provides the elastic force to the rotational force applying member 101 so that the axis X1 of the rotational force applying member 101 forms an included angle a with the axis X2; the rotational force receiving member 210 continues to move in the reverse direction of the X direction, eventually disengaging the rotational force receiving member 201 from the rotational force applying member 101 to the state shown in fig. 3, at which the process cartridge 7 is taken out from the image forming apparatus.
Of course, in another mode of the present embodiment, it is not necessary to provide the inclined surface 211 on the engaging portion 21 during the process of taking out the process cartridge from the image forming apparatus; when the positional relationship between the engaging portion 21 and the recess 11 is moved from the state shown in fig. 6b to the state shown in fig. 6a, the rotational force applying member 101 is disengaged from the top surface 231, and the elastic member 22 provides the rotational force applying member 101 with an elastic force so that the recess 11 is away from the engaging portion 21, so that the rotational force applying member 101 swings; when continuing to move in the direction opposite to the direction X, the elastic member 22 continues to provide the elastic force to the rotational force applying member 101, and the rotational force applying member 101 moves along the inclined surface 232, thereby moving the rotational force applying member 101 to the state shown in fig. 5, and disengaging the recess 11 from the engaging portion 21; when the movement in the opposite direction to the X direction is continued, the rotational force receiving member 201 is disengaged from the rotational force applying member 101, and the process cartridge is taken out from the image forming apparatus.
To ensure that the above-mentioned movement process can be realized, as shown in fig. 6a, there is a distance L between the intersection point of the top surface 231 and the inclined surface 232 on the positioning element 23 and the extreme point of the rightmost side of the engaging portion 21 (i.e. there is no overlap between the top surface 231 and the engaging portion in the axial direction X2), so as to ensure that when the groove 11 is completely engaged with the engaging portion 21 and is no longer pushed by the engaging portion 21 to move rightwards, the rotational force applying member 101 can move along the inclined surface 232 by the distance L, and then the rotational force applying member 101 is abutted against the top surface 231 and positioned by the top surface 231, thereby ensuring that the groove 11 on the rotational force applying member 101 can be sufficiently engaged with the engaging portion 21 and the axis X63 1 of the rotational force applying member.
Fig. 3-6b show the case when the recess 11 is faced to the engaging portion 21 in the process of engaging the rotational force receiving member 201 with the rotational force applying member 101. When the recess 11 is not aligned with the engaging portion 21 during the engagement of the rotational force receiving member 201 with the rotational force applying member 101, as shown in fig. 7, the rotational force receiving member 201 is moved in the direction X shown in the drawing and the rotational force applying member 101 is inserted into the rotational force receiving member 201, the elastic member 22 is compressed to provide the elastic restoring force to the rotational force applying member 101 so that the rotational force applying member 101 swings, and the axis X1 of the rotational force applying member 101 forms an angle a with the axis X2 of the rotational force receiving member 201. When the rotational force applying member 101 continues to move in the X direction shown in the figure, the rotational force applying member 101 abuts against the inclined surface 232, and the inclined surface 232 moves the rotational force applying member 101 along the surface thereof, and the angle a between the axis X1 and the axis X2 is reduced. Since the recess 11 is not opposed to the engaging portion 21 during the engagement of the rotational force receiving member with the rotational force applying member 101, the recess 11 cannot be engaged with the engaging portion 21 during the mounting of the process cartridge to the image forming apparatus, and therefore the rotational force applying member 101 is blocked in the state shown in fig. 8 where the rotational force applying member 101 is blocked by both the engaging portion 21 and the positioning member 23 and the axis X1 forms the angle a with the axis X2. When the process cartridge is continuously mounted to the final working position in the image forming apparatus in the X direction, the relative state of the rotational force applying member 101 and the rotational force receiving member 201 remains in the state shown in fig. 8; when the image forming apparatus starts to operate, the rotational force applying member 101 is rotated, and when the rotational force applying member 101 is rotated to the state shown in fig. 5, the rotational force applying member 101 is moved in the direction opposite to the direction X shown in fig. 5 by the elastic force of the spring 102 and is continuously inserted into the rotational force receiving member 201, and then passes through the position shown in fig. 6a and 6b so that the recess 11 is engaged with the engaging portion 21 and the axis X1 of the rotational force applying member 101 coincides with the axis X2 of the rotational force receiving member 201.
In the present embodiment, the rotational force applying member 101 is capable of both swinging and extending, and the spring 102 provides an elastic restoring force to the rotational force applying member 101, so that the rotational force applying member 101 can swing and extend and then restore to its original state.
Example two:
the same structure and operation as in the first embodiment will not be described again.
As shown in fig. 9, the rotational force receiving member 201 is further provided with a lower positioning member 24, unlike the first embodiment. When the rotational force applying piece 101 is inserted into the rotational force receiving piece 201, the positioning member 23 supports the rotational force applying piece 101 together with the lower positioning member 24, thereby ensuring that the axis X1 of the rotational force applying piece 101 and the axis X2 of the rotational force receiving piece 201 can be coaxial.
Example three:
the same structure and operation as in the first embodiment will not be described again.
As shown in fig. 10, unlike the first embodiment, in the present embodiment, the rotational force applying member 101 cannot be swung and cannot be extended and contracted, and the rotational force receiving member 201 can be swung and extended and contracted. To ensure that the rotational force receiving member 201 can swing and telescope and can transmit the rotational force to the rotating element; the rotational force receiving member 201 is sleeved on the rotational force transmitting member 202, the rotational force transmitting member 202 is provided at one end of the process cartridge, and transmits the rotational force to the rotational member on the process cartridge; a slide rail 25 is provided on the outer circumference of the rotational force receiving member (the present embodiment takes the case where two symmetrical slide rails 25 are provided as an example); the guide rail 26 is correspondingly arranged on the rotating force transmission member 202, an elastic support member 27 is arranged between the rotating force receiving member 201 and the rotating force transmission member 202, and the elastic support member 27 provides elastic restoring force for the rotating force receiving member, so that the rotating force receiving member 201 can swing and stretch and then restore to the original state. When the rotational force receiving member 201 receives the rotational force, the rotational force is transmitted to the rotational force transmitting member 202 by the engagement between the slide rail 25 and the guide rail 26, and the rotational force transmitting member 202 transmits the rotational force to the rotational element on the process cartridge.
The rotating force receiving member which swings and expands in the present embodiment is applicable to a case where the rotating force applying member on the image forming apparatus does not expand and contract nor swings, and also applicable to a case where the rotating force applying member swings but does not expand and contract, or expands and contracts but does not swing, or expands and contracts and swings.
As described in the first and third embodiments, in the case where either one of the rotational force applying member and the rotational force receiving member is both telescopic and swingable and the other is neither telescopic nor swingable, respectively, it can be easily conceived by those skilled in the art that the case where either one of the rotational force applying member and the rotational force receiving member is telescopic or swingable and the other is swingable or telescopic can be applied by appropriately modifying the structure of the third embodiment.
