Abstract

PURPOSE: To enable the detection of film terminal end irrespective of the feed speed of film by detecting the film feed distance from frames in the final and sending signal to film drive control part when the specified amount is fed thereby stopping or reversing the film feed.
CONSTITUTION: In the device of retrieving desired frames on a film by detecting the marks on the film, a pulse generating means 25 which interlocks to the film driving system and a counter 26 which counts the pulses of the pulse generating means 25 and outputs signal when it counts the pulses of the specified number larger than the number of pulses outputted from the pulse generating means 25 at one period of the mark signal generated at each time when the mark detector 22 detects the mark are provided and the film drive system is stopped or reversed by the output signal of said counter 26. This enables the retriever to concentrate in the retrieval work in the case of retrieving desired frames while feeding the film at a low speed.
