Claims

[Scope of utility model registration request]

A screen defining an aperture through which light incident from a subject through a photographing lens passes toward the exposure surface of the film, and having an inner circumferential surface having a slope formed obliquely with respect to the optical axis of the photographing lens. a frame, a shutter curtain provided on the lens side of the screen frame so as to be able to travel along the screen frame, and a shutter curtain provided on the screen frame to protrude toward the opening and directing the light toward the inner circumferential surface. In a focal plane shutter camera equipped with a shielding member that blocks light reflected from the slope and directed toward the film surface in front of the slope, the screen frame includes a lens along the gap and opening on the photographing lens side.
A focal plane shutter camera characterized in that a groove is formed with a depth greater than the thickness of the shielding member, and the shielding member is disposed within the groove.
