Abstract:
A camera comprising:at least one motor;a spindle gear which is a gear having a spindle for rewinding and thrusting a film;a cam that rotates together with the spindle gear when the spindle gear is rotated in a film-rewinding direction and that remains at rest when the spindle gear is rotated in a film-thrusting direction;a direction-limiting mechanism for permitting the spindle gear to rotate in the film-rewinding direction only when the motor is rotating in a forward direction; anda transmission mechanism that comes into contact with the cam when the motor is rotating in a reverse direction such that, when the cam is in one of a plurality of predetermined rotation positions, a driving force of the motor is transmitted to one of a plurality of force transmission destinations to be driven thereby, wherein one of the plurality of transmission destinations is provided for each one of the predetermined rotation positions, respectively;wherein transmission of the driving force of the motor is switched by first rotating the spindle gear in the film-rewinding direction to bring the cam into one of the predetermined rotation positions and then reversing a rotation direction of the motor.
