摄像设备
摘要：
一种摄像设备，包括：能移入和移出摄像光路的反射镜；开闭开口用的快门叶片；与快门叶片连接的叶片杆；沿快门叶片的打开方向偏置叶片杆的叶片返回弹簧；沿快门叶片的关闭方向驱动叶片杆的驱动杆；沿关闭方向偏置驱动杆的叶片驱动弹簧；与叶片杆接合以将叶片杆保持在快门叶片关闭开口的位置的闩锁杆；和能在用于使反射镜位于摄像光路中的第一位置与用于使反射镜位于摄像光路之外的第二位置之间转动的设定杆，从第一位置转动到第二位置的设定杆释放闩锁杆与叶片杆的接合，之后，叶片杆在叶片返回弹簧的偏置力下沿打开方向驱动快门叶片。该设备具有与驱动快门机构相关的小构造，通过使用与快门叶片不同的可动构件而适合于提供摄像元件的清洁机构。
摘要（英）：

An image-pickup apparatus includes a mirror moving into and out of an optical path, a shutter mechanism including shutter blades and a shutter-driving spring driving the shutter blades in an open direction, a charge-holding member holding the shutter mechanism with the shutter-driving spring charged, and a hold-releasing member releasing the holding of the shutter mechanism by the charge-holding member. The shutter blades and the charge-holding member are moved in a plane parallel to a light-receiving surface of an image-pickup element. The hold-releasing member is moved in a plane orthogonalto the light-receiving surface of the image-pickup element and drives the mirror in a moving-out direction when releasing the holding of the shutter mechanism. The apparatus has a small configurationassociated with driving the shutter mechanism and is appropriate for providing a cleaning mechanism of the image-pickup element by using a movable member different from the shutter blades.
