Abstract
PURPOSE: To make the peripheral speeds of pair rollers in a thermal fixing device for a duplicator or the like by permitting drive force to be transmitted to the pair rollers in accordance with the changes of the outer diameter thereof.
CONSTITUTION: A drive gear 4 is rotated by a drive motor 3, and the drive force is transmitted through a uni-directional clutch 6 integrally coupled to the gear 5 to a roller 1 for driving the roller. A pressure application roller 2 is held in forced contact with the outer periphery of the roller 1 and rotated by the frictional forces. The gear 5 is in mesh with a gear 7, and the drive force is transmitted through a uni-directional clutch 8 integrally coupled to the gear 7 to the roller 2 for driving the roller. When the outer diameter of both the rollers is greatly changed due to heat or other causes, a slip is produced in the uni-directional clutch, so that both the rollers are rotated at an equal peripheral speed with the roller 1 being driven.
