发明名称 FINDER DRIVING MECHANISM
摘要 PROBLEM TO BE SOLVED: To simplify configuration of a finder driving mechanism where a finder driving gear is meshed with a gear provided in a lens barrel driving member through an idler gear without providing a cam member separately from the finder driving gear. SOLUTION: The gear 11 of the lens barrel driving member 1 does not have a part meshed with the idler gear 2 in a collapsed state (gear non-existing part 12). The finder driving gear 5 is integrally equipped with end face cams 51 and 53 on which a visual field changing member 72 driving the objective 7 of a finder abuts at both ends as shown by figure 1. Furthermore, the gear 5 is equipped with a stopper member 9 holding the gear 2 in a stop state in the collapsed state. The gear 2 has a flat part 22 on the outer periphery 21 of a shaft part. The stopper member 9 is a torsion coil spring holding the gear 2 in the stop state at the flat part 22 by always abutting on the outer periphery 21 of the shaft part of the gear 2.
