Japanese Patent JPS6364791
Kind Code:
B2
Abstract:
A reproduction apparatus comprises a rotatable drum having trained over its circumferential surface a length of finite belt that extends and is transportable back and forth between two supply reels inside the drum and is impressible with image information to be transferred to receiving material at a transfer station adjacent to the drum surface. During transport of the belt in either direction relative to the drum surface the drum is held at a peripheral velocity which depends upon the direction of the belt transport and, considering both magnitude and direction, is equal to a given processing velocity of the belt relative to the transfer station minus the velocity of transport of the belt over the drum surface. Thus, the transport of the belt relative to the transfer station is always in the same direction and of the same magnitude, whether the belt is being transported from one reel to the other or back from the other to the one reel.
