Abstract

PURPOSE: To prevent a futile photograph by coupling a film counter or a warning device to a detector for film feeding via the electronic control circuit.
CONSTITUTION: Film feed detector is coupled to film counter or warning device via electronic control circuit. Accordingly, the rotation of winding lever is transmitted to shutter sprocket and spool to take a picture. Concurrently, when the film is fed, it is detected by the film feed detector. Its detected sygnal is inputted to electronic control circuit. After counting, if the film feed is regular, the film count progresses. If the film feed is anomalous, the warning device works to issue warning. At the same time, shutter release is obstructed. In addition, at the time of multiple exposures, the signal from R mechanism is inputted into the electronic control circuit so as to prevent its warning or release obstruction.
