1. An electronic device, comprising:
a body;
a disc lid rotatably mounted to the body, the disc lid comprising at least one hook; and
a locking mechanism secured to the body and for locking the disc lid to and unlocking the disc lid from the body, wherein the locking mechanism comprises a sliding bar slidable relative to the body in a longitudinal direction (a first direction) and at least one resisting member secured to the body; the sliding bar is capable of sliding between a locking position for locking the disc lid and an unlocking position for unlocking the disc lid, the sliding bar defining at least one sliding slot, and comprises at least one latching member for hooking the at least one hook when being in the locking position and releasing the at least one hook when being in the unlocking position, the at least one resisting member is slidably received in the at least one sliding slot, and resists the sliding bar against the body to prevent the sliding bar deforming in a second direction perpendicular to the first direction.
2. The electronic device of claim 1, wherein each resisting member comprises a sliding portion secured to the body and a supporting portion secured to an end of the sliding portion away from the body, the sliding portion is slidably received in the at least one sliding slot and engages with the supporting member to resist the sliding bar against the body.
3. The electronic device of claim 2, wherein the length of the supporting portion is larger than the width of the at least one sliding slot.
4. The electronic device of claim 3, wherein the at least one sliding slot extends in a direction parallel to the first direction.
5. The electronic device of claim 1, wherein at least one protruding block projects from an end of the sliding bar, the at least one protruding block defines a first inclined surface.
6. The electronic device of claim 5, wherein the locking mechanism comprises an operating member for driving the sliding bar to slide from the locking position to the unlocking position.
7. The electronic device of claim 6, wherein the operating member comprises at least one resisting portion, the at least one resisting portion defines a second inclined surface engaging with the first inclined surface.
8. The electronic device of claim 7, wherein the operating member further comprises at least one limiting post for preventing the operating member rotating.
9. The electronic device of claim 8, wherein the body defines a recess for receiving the operating member, the bottom of the recess defines an opening for allowing the at least one resisting portion extending through, and at least one limiting hole for receiving the at least one limiting post.
10. The electronic device of claim 1, wherein the locking mechanism comprises an elastic element for providing an elastic force for driving the sliding bar to slide from the unlocking portion to the locking position.
11. The electronic device of claim 10, wherein the sliding bar defines an elongated slot extending longitudinally, a first post protrude from the inner surface of the body, the first post is capable of extending through and sliding along the elongated slot.
12. The electronic device of claim 11, wherein the sliding bar comprises a second post, the second post is arranged adjacent to an end of the elongated slot.
13. The electronic device of claim 12, wherein opposite ends of the elastic element are respectively secured to the first post and the second post.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An image forming device comprising:
a device frame which includes:
a driving device, and
a driving gear that transmits a driving force from the device; and
a photoconductive drum which is inserted in the device frame and includes a driven gear to be engaged with the driving gear,
wherein after the photoconductive drum is inserted in the device frame, by driving the driving device and slightly rotating the driving gear, the driving gear engages with the driven gear, and
wherein the driving gear is slightly rotated at an initializing step of the image forming device.
2. The image forming device according to claim 1, wherein the driving gear is movable along a moving direction of the photoconductive drum, and the device frame includes an urging member that urges the driving gear in an opposite direction from a direction in which the photoconductive drum is inserted.
3. The image forming device according to claim 2, wherein when inserting the photoconductive drum into the device frame, in case a tooth of the driving gear and a tooth of the driven gear contact with one another, by inserting the photoconductive drum further into the device frame, the driving gear is pushed in against an urging force of the urging member.
4. The image forming device according to claim 2, wherein the driving device is a motor fixed on a frame of the device frame, and the driving gear is mounted on an output shaft of the motor in a manner capable of sliding in an axial direction of the output shaft.
5. The image forming device according to claim 4, wherein a key extending over approximately an entire length of the output shaft is fixed on the output shaft, and the driving gear can rotate with the output shaft by the key regardless of where the driving gear is located on the output shaft.
6. The image forming device according to claim 4, wherein the urging member is a coil spring and would around the output shaft between the driving gear and the frame.
7. The image forming device according to claim 4, wherein a shaft hole is formed through the frame, and under a state in which the photoconductive drum is inserted in the device frame, a shaft of the photoconductive drum is inserted through the shaft hole.
