Abstract

PURPOSE: To detect the feed of sheet materials while inversely supplying the sheet materials, by mounting the first and second pulse generating means for detecting feed and revolution, and by comparing the pulses.
CONSTITUTION: Films from a feed reel are sent in the direction of easy flow, and pulses are generated from an amplifier 30 in response to the rotary motions of a capstan roller. Pulses are transmitted from an amplifier 31 by the revolution of the reel. These pulses are each counted by means of counters 35, 36. Since pulse numbers change when the value is not normal and the films fill in a feed passage and are jammed, abnormality is detected. In this case, films are stopped or inversely fed by operating a brake mechanism.
