るレンズ駆動機構付きシヤツタ装置。 An actuator that can be rotated by a predetermined angle in both directions from a reference position is used as a drive source, and the lens is moved via a lens set member that is linked to the reciprocating rotation in one direction of the drive member that rotates integrally with the actuator. In a shutter device in which the opening/closing member is interlocked with the rotation of the drive member in the other direction to perform the opening operation of the shutter blade, the opening/closing member is interlocked with the reciprocating rotation of the drive member in one direction. The shutter blade is arranged so as to rotate back and forth while maintaining the shutter blade in a closed state, and is further provided with a detection means that detects the reciprocating rotation of the opening/closing member or the shutter blade and outputs a signal. A shutter device with a lens drive mechanism.
