Abstract

PURPOSE:To simplify mechanism by eliminating the need for parallel levers, by fitting a slit-forming curtain on shielding curtains of a focal plane shutter consisting of those curtains. CONSTITUTION:On a shaft 7 on a substrate 1 provided with an aperture 1a, shielding curtains 3-6 are pivoted, and the pin 8a of a driving arm 8 rotating around another shaft 9 is engaged with the slot of each curtain to rotate the curtains. The shielding curtains 3 and 4 are provided with pins 3b and 4b, and a slit-forming curtain is fitted through a rotation hole and a long-sized hole 2b. Cam grooves 3a and 4a are designed properly to permit a slit edge 2a to perform parallel movement or prescribed rotation. As a result, a couple of arms for parallel movement are unnecessary. Further, the shielding curtains are able to pivot on the shaft 9 or another shaft partially.
