Abstract:
An object of the present disclosure is to increase a frame speed at the time of performing continuous shooting in a shutter drive device by controlling a charge member by using a position sensor and a temperature sensor. The shutter drive device of the present disclosure includes: a shutter mechanism; a charging member that drives the shutter mechanism by using a plurality of gears, a rack member, and a motor; the temperature sensor mounted on the charging member; a position sensor that is mounted on the charging member, and detects the rack member moved to a predetermined position; and a control part that controls stop timing of the motor based on a position of the rack member detected by the position sensor and a temperature detected by the temperature sensor.
