Abstract

Abstract A self-developing camera adapted to be folded into a compact form which is very small relative to the picture size. The camera includes three housing sections pivotally connected to one another for movement between a folded position and an erect position in which the sections define three sides of a lighttight chamber, one section including a lens and shutter, another section including means for locating a photosensitive element in position for exposure, and the third section including a mirror for reflecting light from the lens toward a photosensitive element positioned for exposure; and erecting system including a pair of support members for rigidly retaining the housing sections in the erect position; and means such as a viewfinder, a rangefinder, and/or means for supporting a photoflash unit, mounted on the support member for movement between a folded position in which the last-mentioned means are engaged in an external recess and erect position in which these means are operatively oriented with respect to the lens axis.
