Abstract
A power transmitter, including a driving gear rotated by a driving motor, a driven gear rotatably coupled with the driving gear through a coupler, and a power interruption unit to be broken when the driven gear is overloaded so as to release the coupling between the driven gear and the coupler such that power transmission to the driven gear is cut off.
Claims15
A power transmitter, comprising:
- a driving gear rotated by a driving motor;
- a driven gear rotatably coupled with the driving gear through a coupler;
- and
- a power interruption unit to be broken when the driven gear is overloaded so as to release the coupling between the driven gear and the coupler such that power transmission to the driven gear is cut off.
A developing device driver of an image forming apparatus, comprising:
- a driving unit having a driving motor mounted to a main body of the image forming apparatus;
- a driven unit having a plurality of driven gears provided to a developing device removably mounted to the main body of the image forming apparatus;
- a coupler interconnecting the driving unit and the driven unit as the developing device is mounted to the main body, to allow for power transmission between the driving unit and the driven unit;
- and
- a power interruption unit to break when the driven unit is overloaded so as to release the coupling between the driven unit and the coupler such that the power transmission to the driven unit is cut off.
A developing device driver of an image forming apparatus in which power from a driving motor, which is normally transmitted to a driven gear on the developing device through a coupler coupled to the driven gear, is cut off when the coupling between the coupler and the driven gear is broken as a result of an overload of driving torque provided by the driving motor.
