The mounting slot 62 extends from the housing 61 in opposite radial directions and is open to The top wall 64, the two limiting slots 63 are adjacent to the mounting slot 62 and extend parallel to the imaginary axis L. The two limiting slots 63 are not open to the top wall 64. The sleeve 30 further has two protrusions 34. The body 32 protrudes out. When assembled, the two protrusions 34 of the sleeve 30 are inserted into the housing 61 through the mounting groove 62, and then the sleeve 30 is rotatable such that the two protrusions 34 enter the limit. The slot 63, the sleeve 30 is limited to the gear member 60. The details of these embodiments are disclosed in the TW 102124445 application, which is not described herein.

The assembly of the transmission assembly of the present invention is relatively simple. First, the elastic member 50 is placed in the shaft hole 322 of the sleeve 30. As shown in FIG. 9A, the shaft hole 322 of the sleeve 30 communicates with the gear. The housing 61 of the member 60, and secondly, the shaft 70 of the transmission member 20 is inserted into the shaft hole 322 of the sleeve 30, as shown in the ninth FIG. 9B, and then the pin 40 is passed through the groove of the gear member 60. 69 and the guiding groove 324 of the sleeve 30 penetrates into the insertion hole 73 of the shaft 70 of the transmission member 20, so that the two ends of the bolt 40 (ie, the two protrusions 75) can be moved and moved. The two ends of the elastic member 50 are respectively abutted against the bottom wall 65 of the gear member 60 and the second end 72 of the shaft 70 of the transmission member 20, and the elastic member 50 is generated. The elastic force acts on the second end 72 of the shaft 70 of the transmission member 20 along the imaginary axis L, so that the transmission assembly 100 is in the normal state, the pin 40 of the shaft 70 (that is, the two projections 75) ) abutting against the top or top of the two guide grooves 324 of the sleeve 30.

When the transmission assembly 100 is used, the gear member 60 is fixed to one a photosensitive drum (not shown) for use in the toner cartridge, the snap-fit structure 80 of the transmission member 20 is extended from one end of the toner cartridge, and the user puts the toner cartridge into an electronic imaging device. In the housing (not shown), the latching structure 80 of the transmission member 20 is engaged with a driving member 90 in the housing of the electronic imaging device (as shown in the tenth to twenty-fourth drawings), such that The portion of the driving member 90 is received in the accommodating space 86. The two hooking slots 823 are formed by the two protrusions 92 of the driving member 90 and are engaged. The driving member 90 is driven to rotate.

10 to 14 are diagrams showing a process of connecting the transmission assembly 100 of the photosensitive drum to a driving member 90 in the first preferred embodiment of the present invention. In order to more clearly illustrate the carding process, the engaging block 82 is shown. Each of the following is represented by a first card block 82A and a second card block 82B.

As shown in FIG. 11 and FIG. 11A to D, the outer side surface 825 of the first latching block 82A is in contact with the driving member 90, and the latch 40 of the shaft 70 (ie, the two bumps 75) is Located at an intermediate position of the two guide grooves 324 of the sleeve 30 and abutting the top edge 324T or the apex, at this time, the gear member 60 rotates counterclockwise and the transmission member 20 pushes against the driving member 90 toward the first direction D1. The pin 40 of the shaft 70 is first moved along the top edge 324T of the guide groove 324, and then slides along the inclined portion 324S of the side of the guide groove 324 toward the second direction D2, as shown in FIG. As shown in D, the elastic member 50 is pressed against the bottom wall 65 of the gear member 60. As shown in FIG. 12B, when the transmission member 20 continues to push against the driving member 90, the shaft 70 is The latch 40 is moved in the guiding groove 324 toward the second direction D2, as shown in FIG. 13 AC. At the same time, the elastic member 50 is pressed against the bottom wall 65 of the gear member 60, as described in As shown in FIG. B, the driving member 90 is slid into the accommodating space 86 of the transmission member 20. When the driving member 90 is received in the accommodating space 86 of the transmission member 20, the compression generated by the elastic member 50 is generated. The elastic force pushes against the shaft 70, so that the latch 40 of the shaft 70 returns to the middle position of the two guide grooves 324 of the sleeve 30 to abut the top edge 324T or the apex, and the two hook slots 823 are respectively engaged. The two studs 92 of the driving member 90 are as shown in Figs. 14A to A.

The above process is equivalent to the process of pushing the driving member 90 toward the gear member 60 (ie, toward the second direction D2) against the transmission member 20, so that the transmission member 20 rotates clockwise and along the shaft hole 322 of the sleeve 30. Moving inwardly, the projection 75 is guided by the guide groove 30 of the sleeve 30 to rotate the transmission member 20. One of the protrusions 92 of the driving member 90 is along the inclined top of the first engaging block 82A. The face 822 slides and passes through the top end 821 of the first snap block 82A. Thereafter, the transmission member 20 is no longer pushed against the drive member 90, but is subjected to the repulsive force generated by the elastic member 50 and along the sleeve 30. The shaft hole 322 is outwardly moved (ie, facing the first direction D1) and rotated at the same time. Then, the two hook slots 823 are respectively engaged with the two protrusions 92 of the driving member 90.

Therefore, when the driving member 90 rotates counterclockwise, the two protrusions 92 respectively push the respective engaging blocks 82A and 82B to rotate the transmission assembly 100 counterclockwise. At this time, the two hook slots 823 and The locking of the two protrusions 92 prevents the rotating transmission member 20 from moving inward along the shaft hole 322 of the sleeve 30 (ie, toward the second direction D2), and the driving member 90 can drive the transmission assembly. The two protrusions 92 of the driving member 90 abut against the concave portion 823a of the hooking groove 823 as shown in FIG. 14 , but those skilled in the art should also understand the two protruding posts. 92 can also abut against the limiting surface 823b of the hook slot 823. Both of the conditions have a transmission effect, that is, the two protrusions 92 of the driving member 90 abut against the recess 823a or the limit. In the face 823b, the transmission assembly 100 can be driven to rotate.

The fifteenth to nineteenth drawings show another process of connecting the transmission assembly 100 of the photosensitive drum provided by the first preferred embodiment of the present invention to a driving member 90, which is the same as the tenth to fourteenth drawings. The process is reversed.

The middle position of the guiding groove 324 abuts against the top edge 324T or the apex. At this time, the gear member 60 rotates clockwise and the transmission member 20 pushes against the driving member 90 toward the first direction D1, so that the pin of the shaft 70 is inserted. 40 first moves along the top edge 324T of the guide groove 324, and then slides along the other inclined portion 324S of the two sides of the guide groove 324 toward the second direction D2, as shown in FIGS. 17A to C. The elastic member 50 is pressed against the bottom wall 65 of the gear member 60. When the transmission member 20 continues to push against the driving member 90, the latch 40 of the shaft 70 continues in the guiding groove 324 toward the second direction D2. Moving, as shown in FIG. 18B, at the same time, the elastic member 50 is further pressed against the bottom wall 65 of the gear member 60, as shown in FIG. 18A, and the driving member 90 is slid into the transmission member. When the driving member 90 is received in the accommodating space 86 of the transmission member 20, the compressive elastic force generated by the elastic member 50 pushes against the shaft 70, so that the pin 40 of the shaft 70 is again return The sleeve 30 is opposite to the top edge 324T or the apex of the second guide groove 324. The two hook slots 823 are respectively engaged with the two protrusions 92 of the driving member 90, as shown in FIG. 19A to C. Shown.
