The guide end surface 449 and the guide inclined surface 449a extend into the slot 445 of the clamping member 44, and when the coupling member 32 swings until the rotational force transmission part 322 has completely inserted into the slot 445, as shown in FIG. 16 As shown, the coupling member 32 has rotated approximately 90 degrees, at this time, the second imaginary axis L2 is coaxial with the first imaginary axis L1, and the coupling member 32 and the clamping member 44 are snapped together to be able to work together. Rotate, in fact, when the coupling piece 32 extends into the slot 445, the coupling piece 32 is no longer pressed against the engaging member 44, and the engaging member 44 can be supported by the second elastic member 46 The elastic force of the driving head 3 moves toward the direction of the driving head 3 and pushes against the shaft seat 36, so that the coupling member 32 moves to the second position P2 upward in FIG. In the central depression 321b of the force receiving portion 321, the two locking posts 321c (not shown in FIG. 16 due to the angle relationship) of the coupling member 32 and the two driving ribs (not shown) of the driving head 3 are engaged with each other. The coupling part 32 can be rotated by the driving of the drive head 3, and the clamping part 44 is driven to rotate through the rotational force transmission part 322, and the clamping part 44 is then passed through the two transmission arms 443 (due to the angular relationship not in the Figure 16 shows) can drive this gear 4 2 rotates, whereby the rotational kinetic energy of the drive head 3 can be transmitted to the photosensitive drum 20, and the photosensitive drum 20 can conduct electricity through photosensitive action and at the same time absorb toner to develop images and print documents.

In fact, when the coupling member 32 swings from the first position P1 to the second position P2, the pin 322c of the rotational force transmission portion 322 may not be accommodated initially due to the angular relationship. In the embedding groove 445, but against the arc wall 448 of the clamping member 44, as shown in FIG. The two pins 322c slide from high to low along the two guiding end surfaces 449, and when rotated to be roughly parallel to the extending direction of the slot 445, the snap-fitting part 322c is then combined with the elastic force of the second elastic part 46 44 pushes against the direction of the coupling member 32, so that the pin 322c can automatically extend into the slot 445, as shown in FIG. 18 . More specifically, the design of the two guiding end surfaces 449 can facilitate the coupling member 32 to be inserted into the slot 445 more easily.

Please refer to FIG. 19 to FIG. 24 , which illustrate the process of the toner cartridge 1 detaching from the driving head 3 of the electronic imaging device 2 in the direction indicated by the arrow in the drawings. The toner cartridge 1 may have two different situations when it is detached. The first situation shown in FIGS. The extension direction of the groove 445 is not consistent, so the coupling member 32 cannot directly start to swing from the second position P2. In this situation, the coupling member 32 must first move away from the first imaginary axis L1. The direction of the clamping member 44 moves; in more detail, since the central depression 321b of the coupling member 32 is tapered and the position of the driving head 3 remains unchanged, when the toner cartridge 1 moves to the left in FIG. 19 , the inner wall of the central depression 321b will be pressed against by the drive head 3 first, and at this time, the space provided by the slot 445 allows the coupling member 32 to swing slightly and lean against one of the arc walls 448, as shown in FIG. As shown in FIG. 20; as the toner cartridge 1 continues to move to the left, as shown in FIG. The shaft seat 36 pushes against the guide end surface 449 of the engaging member 44 and overcomes the elastic force 46 of the second elastic member to move downward together; when the toner cartridge 1 continues to move to the left, the drive head 3 and The coupling part 32 is separated, that is, the coupling part 32 is no longer pressed against by the drive head 3, as shown in Fig. 22 and Fig. 23, the engaging part 44 is moved upward by the elastic force of the second elastic part 46, Push against the shaft seat 36 to move upwards, and at the same time, the shaft seat 36 is affected by the elastic force of the first elastic member 38 and slides along the two sliding grooves 342 in a direction away from the coupling assembly 40 until the rotational force transmission part 322 is completely After disengaging from the socket 445, the shaft seat 36 is subjected to the elastic force of the first elastic member 38 and rotates clockwise together with the coupling member 32, so that the shaft portion 323 of the coupling member 32 leaves the opening. 340 , and finally make the coupling member 32 return to the first position P1 , as shown in FIG. 24 , that is to complete the detachment of the toner cartridge 1 from the driving head 3 .

In actual disengagement, the above-mentioned second situation may also be encountered: the extension direction of the slot 445 is consistent with the swing path of the coupling member 32, so the coupling member 32 can be directly moved from the second position P2 swings to the first position P1; when starting to swing, the driving head 3 will first break away from the central depression 321b, and with the movement of the toner cartridge 1, the driving head 3 will then abut against the middle of the coupling member 32 A clamping post 321c makes the shaft seat 36 press against the clamping member 44 toward the direction of the coupling assembly 40, and the clamping member 44 moves downward against the elastic force of the second elastic member 46; As the connector 32 continues to swing, the rotational force transmission part 322 gradually leaves the slot 445, and the engaging member 44 is no longer pressed by the shaft seat 36 and moves upwards under the elastic force of the second elastic member 46. The shaft seat 36 is subjected to the elastic force of the first elastic member 38 and slides upward along the two slide grooves 342 in a direction away from the coupling assembly 40 , and the shaft seat 36 is also subjected to the elastic force of the first elastic member 38 and together with the coupling The connecting member 32 rotates clockwise together, and finally the coupling member 32 returns to the first position P1, that is, the separation of the toner cartridge 1 from the driving head 3 is completed.

Therefore, whether the toner cartridge 1 is assembled into the electronic imaging device 2 or removed from the electronic imaging device 2 , the process of assembling and disengaging it with the driving head 3 is simple and smooth. Moreover, when the toner cartridge 1 has not been incorporated into the electronic imaging device 2 or even has not been in contact with the drive head 3, the coupling member 32 at the first position P1 is shielded by the cover member 34 to avoid being hit by foreign objects or click the tab to reduce the risk that the toner cartridge 1 may be damaged.

Based on the spirit of the present invention, the structure of the toner cartridge 1 can be changed, for example: the structure of the joint assembly 30 and the coupling assembly 40 can be changed arbitrarily and is not limited to the above, but the coupling member 32 must be able to When moving between the first position P1 and the second position P2, and the coupling member 32 is located at the first position P1, the second imaginary axis L2 is not parallel to the first imaginary axis L1, and the coupling member 32 is not parallel to the first imaginary axis L1. In contact with the coupling assembly 40, when the coupling member 32 is located at the second position P2, the second imaginary axis L2 is coaxial with the first imaginary axis L1, and the coupling member 32 and the coupling assembly 40 are clamped together And can rotate together.

Certainly, the present invention also can have other various embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the protection scope of the claims of the present invention.
