ABSTRACT:
An electric wind-up device for driving a film feed mechanism in a camera after exposure comprises wind-up terminating means for detecting an increase in resistance in the film feed mechanism to stop rotation of a motor when the film has been wound up by one frame or completely drawn out of a magazine, and counter means for counting the exposed frames and generating a count signal when a predetermined number of frames are counted. The wind-up device further comprises means co-operating with the counter means for outputting a motor energizing signal after exposure. The co-operating means outputs the motor energizing signal even when the count signal is not energized.
