Abstract
PURPOSE: To prevent the reverse incident light from the finder with simple constitution by providing a light-shielding plate which is movable parallel with the main mirror plane to the supporting substrate of a main movable mirror, moving the light-shielding plate synchronously with the turning of the main mirror, opening the semi-transparent mirror part of the main mirror at the observing and shutting the same at the exposing.
CONSTITUTION: A main half mirror 21 is adhered to the convex parts 22-aW22-c of a mirror carrier 22. Distance-measuring light is led in through the opening 22-h of the mirror carrier 22. A lever 23 pivotally supported rotatably by a pin 24 is mounted to the mirror carrier 22, and a light-shielding plate 26 pivotally supported rotatably by a pin 25 is mounted to its end. The other end of the lever 23 is engaged in the cam groove provided in a guiding plate 30 fixed to the camera body. The light-shielding plate 26 is in contactual touch with projecting parts 22-f, 22-g. At the exposing, the mirror rotates upward around the shaft 31, then the light-shielding plate 26 shields the opening 22-h by way of the lever 23 guided by the cam groove, thereby preventing harmful light. Besides, the constitution is extremely simple.
