ABSTRACT:
A lens shutter has a diaphragm blade, a shutter blade, and a motor with a rotor reciprocatingly turned between an initial position and a final position by a current applied to a coil, to move the diaphragm blade to stop at an aperture regulating position and the shutter blade between an aperture open position and an aperture close position in cooperation with a first forcing member urging the diaphragm blade toward the aperture regulating position, a stopper for keeping the diaphragm blade at the aperture regulating position and a second forcing member urging the rotor against movement for the final position at least after the diaphragm blade abuts on the stopper. A magnetic device is provided to keep the rotor at positions where the aperture is fully opened and closed, respectively, even when the current to the coil is interrupted.
