Mechanism for adjusting an angle of a mirror incorporated in an optical device, and a parallax correcting mechanism of a camera

摘要

A parallax correcting mechanism of a camera includes a mirror; a mirror frame supporting the mirror; a pair of pivotal-point projections formed on a viewfinder body to lie on a mirror rotational axis of the mirror; a pair of recesses formed on the mirror frame or the viewfinder body; a pair of projections formed on the mirror frame or the viewfinder body to be engaged in the pair of recesses; a leaf spring for pressing the mirror frame against the pair of pivotal-point projections; and an adjusting screw which is screwed into the viewfinder body on one side of the mirror frame with respect to the mirror rotational axis. A flat face of a head of the adjusting screw contacts an end portion of the one side of the mirror frame.
