    • 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.
    • 一种快门装置,包括:第一遮光单元; 第二遮光单元; 支撑构件; 和充电部件。 快门装置具有简单的结构,其不需要在快门装置和外部单元之间指定的互锁机构,并且允许第二遮光单元保持在快门孔部分打开的状态而不必保持 第二遮光单元。 支撑构件可突出到第二遮光单元的移动路径中,以将第二遮光单元保持在快门孔部分打开的状态。 响应于充电构件的移动,支撑构件从第二遮光单元的移动路径突出或退回,该充电构件用于对第一和第二遮光单元充电。
