摘要： A shutter drive device includes a base member, an actuator, a first drive member, and a second drive member. The actuator is fixed to the base member and produces a driving force to drive the shutter mechanism. The first drive member is rotatably supported by the base member and configured to be rotated by the driving force. The second drive member is supported by the base member so as to be linearly movable in a first direction and configured to transmit the driving force of the actuator to the shutter mechanism. The first drive member has a gear component to drive the second drive member in the first direction, and a cam component configured to hold the second drive member in a specific position. The second drive member has a rack gear configured to mesh with the gear component, and a cam follower configured to contact the cam component.
