Abstract
A mirror recoil preventing device suitable for a camera has a mirror and a mirror support frame. The mirror support frame movably supports the mirror in movement from a first position to a second position. In a camera having a photographic lens and a range finding element, the mirror guides light from the photographic lens to the range finding element when positioned at the second position. As a first alternative, the mirror support frame has a U-shaped groove at one end thereof. A regulating member is located in the vicinity of the second position to engage with the U-shaped groove when the mirror support frame is at the second position. As a second alternative, the mirror support frame has a leading edge and a trailing edge such that in movement from the first position to the second position, the trailing edge trails the leading edge. A first regulating member is located to be immediately adjacent to the leading edge of the mirror support frame when the mirror support frame is at the second position. A second regulating member is located to be immediately adjacent to the leading edge of the mirror support frame when the mirror support frame is at the second position.
