Abstract
PURPOSE: To automatically perform rewinding of film after photographing of the specified frame number by providing such a mechanism and circuit that performs shutter charging and film winding and performs rewinding at the ending of photographing by reverse running the motor.
CONSTITUTION: The winding amount defining mechanism 4 of a film 1 is so provided as to interlock to shutter release. With the state of film being held loaded, the switch S2 of the circuit is ON and therefore if the switch S3 is turned ON, current flows in the direction of the arrow (a) through TrQ7WQ9 via resistance R11 and after the winding is done for a certain length, the switch S2 is turned OFF to stop the motor. The time constant of R3C1 is beforehand set slightly longer than the normal winding time t1 and the time constant of R5C2 slightly longer than the normal rewinding time t2. If the S2 is ON longer than t1, the Q2 goes ON and the current in the arrow (b) direction flows in the motor M which then makes rewinding. After t2, the Q3 goes ON to turn OFF Q4WQ6, thereby stopping the motor M.
