Title:
PHOTOGRAPHIC CAMERA APPARATUS
Document Type and Number:
Japanese Patent JPS5449127
Kind Code:
A
Abstract:
A "scanning type" photographic shutter blade mechanism is manually actuated to open, thereby commencing a photographic exposure cycle, by a resilient opening drive element. The "scanning type" shutter blade mechanism is thereafter closed to terminate the photographic exposure cycle by deenergizing an electromagnet which in turn releases a shutter blade closing drive member resiliently biased to engage the shutter blade mechanism and move it to the closed position against the yieldable bias of the opening drive element. Subsequent manual deactuation of the camera operates to recock the shutter blade closing drive member so as to ready the camera for a subsequent photographic exposure cycle.
