| 发明名称 | Focal plane shuttering apparatus and image capture device | ||
| 摘要 | This focal plane shuttering apparatus includes: front and rear curtains; first and second elastic members which generate biasing force to make the front and rear curtains run in such a direction as to get the front and rear curtains retracted from an aperture; a charging member which applies biasing force to those elastic members; a front curtain locking member which keeps the front curtain retracted from the aperture when the charging member applies biasing force to the first elastic member; a rear curtain locking member which keeps the aperture covered with the rear curtain when the charging member applies biasing force to the second elastic member; two switches which turn synchronously with those locking members; and an unlocking member which is interlocked with the charging member that unlocks those locking members. | ||

| 主权项 | 1. A focal plane shuttering apparatus comprising: a shutter base plate with an aperture; a front curtain which is movable between a position where the front curtain covers the aperture and a position where the front curtain is retracted from the aperture; a first elastic member which generates biasing force to make the front curtain run in such a direction as to get the front curtain retracted from the aperture; a rear curtain which is movable between a position where the rear curtain covers the aperture and a position where the rear curtain is retracted from the aperture; a second elastic member which generates biasing force to make the rear curtain run in such a direction as to have the rear curtain cover the aperture; a charging member which applies biasing force to the first and second elastic members; a front curtain locking member which keeps the front curtain retracted from the aperture when the charging member applies biasing force to the first elastic member; a first switch which turns synchronously with the front curtain locking member; a rear curtain locking member which keeps the aperture covered with the rear curtain when the charging member applies biasing force to the second elastic member; a second switch which turns synchronously with the rear curtain locking member; and an unlocking member which is interlocked with the charging member that unlocks the front and rear curtain locking members. | ||
