<p>PURPOSE:To eject paper from a fixing device by driving a fixing roller and an ejecting roller by using a manual driving device when the paper is stopped in the fixing device and to easily interrupt connection with a driving device in the case of driving the respective rollers by using the manual driving device. CONSTITUTION:An intermediate gear 13 is arranged between the driving gear 12 of the fixing device 1 and a transmitting gear at a downstream part, and the manual driving device 20 functioning as a means for interrupting driving is arranged between the gear 13 and a shaft member 21. In the case a pin 23 provided on the shaft member 21 is engaged with an engaging member 25 provided in the gear 13 to be driven in a paper feeding direction, the action of transmitting driving force is performed in the device 20 in a state where the pressing surface 26 of the engaging member presses the member 21 through the pin 23. On the other hand, in the case of rotating the member 21 by using a knob member 22, the connection of the driving system of the driving device is interrupted in a state where the pin 23 is disengaged from the member 25, and a roll device is manually rotated.</p> |
