Document Type and Number:
Japanese Patent JP3927213

Abstract:

PROBLEM TO BE SOLVED: To improve image quality by preventing film move during exposure.
SOLUTION: When a shutter release 6 is depressed, a pressing rod presses a falling member 91c of a locking lever 91 and the locking lever 91 is turned counterclockwise. A pawl 91a engages with a pressing protrusion 67b even in a state immediately before engagement of an engaging protrusion 94 and a protrusion 95 to be engaged is released. When the locking lever 91 is further turned counterclockwise, engagement of the engaging protrusion 94 and the protrusion 95 to be engaged is released and a shutter driving lever 92 is turned counterclockwise. A shutter aperture is opened and closed and photo film 22 is exposed. Turning of a driven sprocket wheel 98 is prevented until the pawl 91a gets out of a groove 97a in an anti-winding cam 97.
