Title: Focal plane shutter for camera
Inventor: TAKAHASHI SHIGEMI
IPC: G03B9/36
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a focal plane shutter for a camera having a light shielding wall effective in preventing the leakage of light. SOLUTION: An intermediate plate 18 is placed between a shutter base plate l arranged on a lens side and an auxiliary base plate 26 arranged on the side of a film, to partition them and constitute two blade chambers. The light shielding wall 26t for shielding the peripheral parts of two base plates 1 and 26 is provided in the auxiliary base plate 26. The inside surface of the light shielding wall 26t is formed as a slope 26t2 , to make the distance from an optical axis greater as it goes from the auxiliary base plate 26 to the shutter base plate 1. Therefore, the light entering from the peripheral parts can be intercepted.  Further, the light after entering into the gap between the base plate 1 and a blade group arranged in the blade chamber on the side of the base plate 1, from its aperture 1a is mainly reflected toward the base plate 1 by the slope 26t2 on purpose, to be attenuated, so that the light entering into the gap between the intermediate plate 18 and the auxiliary base plate 26 can be suppressed.
