Abstract

In a motor drive device for long-footage film having a first motor for effecting shutter release and for driving a constant-amount film feeding sprocket and a second motor for starting to drive to effect take-up of the film onto a spool upon starting of movement of the sprocket, there is provided a timing circuit for generating a shutter release signal which drives the first motor to effect shutter release immediately after the complete stoppage of the second motor and which effects film take-up immediately after completion of the shutter release. The timing circuit repetitively generates such a shutter release signal at a time interval from the shutter release to the complete stoppage of the second motor.
