Abstract

PURPOSE:To shorten the flange back of a camera by preparing a link mechanism with which a component force to the backward part of the optical axis of an object acts to a reflecting mirror in case of moving from a mirror down position to a mirror up position. CONSTITUTION:A pair of driving levers 4 rotates counterclockwise centering around a 1st supporting shaft 6 and a mirror holder 1 moves backward and rises as a whole through a 1st fulcrum pin 2a until the driving lever 4 is positioned in parallel with the optical axis l1 of the object. A sublever 5 also rotates counterclockwise centering around a 2nd supporting shaft 7 through the mirror holder 1. In such a case, if the mirror holder 1 rotates clockwise centering around a 2nd fulcrum pin 3 and the driving lever 4 is turned counterclockwise from the position parallel with the optical axis l1, the mirror holder 1 moves to a mirror-up state nearly without protruding its front end forward from the mirror-down position.
