Abstract

PURPOSE: To enhance the angular accuracy of a movable mirror by disposing the central part of the movable mirror on the optical axis of subject rays and turning the mirror with the optical axis as its axis.
CONSTITUTION: A mirror holding barrel 5 consists of a large diameter barrel part 5a fitting onto the small diameter rear part 4b of a stationary holding member 4 and a small diameter barrel part 5b having a gear 5e connecting to a mirror driving member, and a movable mirror 6 is secured to the mirror mounting face 5c formed within the large diameter barrel part 5a. An opening 5d is formed in the large diameter barrel part 5a. At the observing of the subject image, the opening 5d is stopped in the position where it overlaps with the opening 4c of the finder optical path of the stationary holding member 4 to lead the subject rays reflected by the mirror 6 to a stationary reflecting mirror 7 of the finder system, thus the photographer is able to see the subject's image through the eyepiece disposed behind the stationary mirror 7.
