Abstract: A blade driving device is smaller and has fewer components. A blade driving device includes a base including a support shaft extending frontward, a cover having an opening, a blade located in a blade chamber defined between the base and the cover, and an actuator that moves the blade between a closing position to cover the opening and an opening position to uncover the opening. The cover covers a front of the base. The actuator includes a lever connected to the blade. The lever includes a lever body rotatable about the support shaft in the base, a connector connecting the lever body and the blade, and a protrusion protruding from the lever body frontward beyond the blade and facing the cover.

Abstract: A shutter apparatus includes a shutter base having an opening, a light shield configured to reciprocate between a closed state that closes the opening and an open state that opens the opening, a motor, a cam member configured to move the light shield when the cam member is rotated by the motor, and a restricting member configured to contact the cam member and to restrict the cam member from rotating in a first direction and in a second direction different from the first direction, the restricting member being rotatable and including a rotary damper engaged with the cam member. The restricting member is located at different positions in a rotating direction between when the restricting member restricts the cam member from rotating in the first direction and when the restricting member restricts the cam member from rotating in the second direction.
