ABSTRACT:
A viewfinder assembly which comprises a viewfinding mirror module of one-piece construction including a pair of major roof mirrors laid at a predetermined acute angle (90.degree.) relative to each other, side walls continued from respective lower edges of the roof mirrors to support such roof mirrors and an eyepiece support frame positioned rearwardly of the viewfinding mirror module. Each of the side walls has a lower edge formed integrally with elastic fitting pawls for the fitting of the viewfinding mirror module to the camera body. In order to mount the viewfinding mirror module, the viewfinding mirror module is first mounted on the viewfinder holder with the fitting pawls engaged in holes in the viewfinder holder. To connect the eyepiece to the viewfinding mirror module, the eyepiece is retained in position between a light measuring lens holder fixed on an upper surface of the eyepiece support frame and the major roof mirrors which are covered by the protective cover above which the flexible printed circuit board is mounted.
