シヤツター装置。 A drive motor which is compressed by a return spring so that the rotary arm attached to the end of the output shaft normally occupies a fixed rotation position, a lens drive member which can be stopped at the set position and the extended position, and a blade opening. and a locking lever that holds the opening/closing lever biased by a spring so that the blade is in the closed state, and is moved to the set position via the rotating arm by forward rotation of the drive motor. enabling the lens driving member to be brought to the extended position, and releasing the stoppage of the locking lever via the rotation arm by reverse rotation of the drive motor to rotate the opening/closing lever; The blades are brought into the closed state again after a desired time elapses after the start of rotation of the opening/closing lever by an ON signal from a starting switch of an electric time control circuit which is turned ON/OFF by the rotation of the opening/closing lever. The driving motor is rotated in the forward direction to rotate the opening/closing lever via the rotating arm against the elasticity of the opening spring, and after closing the blade, the driving voltage of the driving motor is turned off. A shutter device with a lens drive mechanism, wherein the drive arm of the drive motor returns to the fixed rotational position by the elasticity of the return spring.
