DRIVING CONTROLLER OF APERTURE DIAPHRAGM OF CAMERA

摘要

PURPOSE:To make a mechanical signal from a photographic operation mechanism other than an aperture diaphragm device unnecessary, by providing an engaging and disengaging mechanism which restores an aperture diaphragm setting mechanism by the restoring motion of an aperture diaphragm interlocking mechanism. CONSTITUTION:The engaging and disengaging mechanism which restores the aperture diaphragm setting mechanism by the restoring motion of the aperture diaphragm interlocking mechanism is provided between the aperture diaphragm interlocking mechanism and the aperture diaphragm setting mechanism. This engaging and disengaging mechanism consisting of a restoration operating pin 2b stood on an aperture diaphragm ring 2 of the aperture diaphragm interlocking mechanism, a pin 12C to be operated for restoration which is stood on an aperture diaphragm setting member 12 of the aperture diaphragm setting mechanism, and a restoring lever 18 provided with an arm 18a to be operated upon which the restoration operating pin 2b of the aperture diaphragm ring 2 acts and an acting arm 18b which gives the restoring action to said pin 12C of the aperture diaphragm setting member 12.
