ABSTRACT:
A shutter device includes a first light-blocking unit; a second light-blocking unit; a supporting member; and a charging member. The shutter device has a simple structure that does not require a designated interlocking mechanism between the shutter device and an external unit, and that allows the second light-blocking unit to be maintained in a state where a shutter aperture portion is open without having to hold the second light-blocking unit electrically. The supporting member is protrudable into a movement path of the second light-blocking unit to maintain the second light-blocking unit in a state where the shutter aperture portion is open. The supporting member protrudes into or recedes from the movement path of the second light-blocking unit in response to a movement of the charging member, which is provided for charging the first and second light-blocking units.
