DRIVE TRANSMISSION, AND ORIGINAL CONVEYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drive transmission and an original conveying device which can prevent a driven pulley from being moved toward a driving pulley even when the torque of a drive source changes rapidly. SOLUTION: The driving pulley 133 is fixed to a shaft 131a of a drive motor mounted on a body cover 52. The driven pulley 134 is fixed to an axial end of a rotor of a conveyance unit 54 attached to the body cover 52 freely movably in the vertical direction. A timing belt 132 is extended between the driven pulley 134 and the driving pulley 133. An arm member 135 is connected to the conveyance unit 54 and the body cover 52 in such a manner that it extends on and along a line connecting the center of the driving pulley 133 and the center of the driven pulley 134.
