Abstract

PURPOSE: To vary the film feeding speed to effect synchronism between film and a tape by varying the transmission ratio of a transmission mechanism in accordance with the difference between the pulse numbers, which correspond to the film feeding speed, and the pulse numbers which correspond to the tape running speed.
