PROBLEM TO BE SOLVED: To provide a digital still camera capable of suitably discharging wearing powder produced from a focal plane shutter to the outside of the camera. SOLUTION: A thin plate member 8 with transparency is placed between a solid-state imaging element 2 and the focal plane shutter 3 attachably/detachably to/from the outside of the camera 1. A shield member 7 made of an elastic material is fitted to a wall at the side of the focal plane shutter 3, and its free end has the habit of coming into contact with a wall at the side of the solid-state imaging element 2 in an ordinary state, but in the case of mount state of the thin plate member 8 or during a mount/removal operation of the member 8, the free end always comes into contact with the thin plate member 8. Then in the case of a removal operation, the wearing powder adhering to the thin plate member 8 is scraped by the shield member 7 and deposited on the shield member 7, but an adhesive material provided to a step difference part between the shield member 7 and a thin thickness part 8c (e.g., double-sided tape) 9 catches the wearing powder and discharges the wearing powder to the outside of the camera 1. Thus, no wearing powder or the like produced from the focal plane shutter adheres to an image forming face of the solid-state imaging element. COPYRIGHT: (C)2004,JPO&NCIPI |
