Description

ABSTRACT:
A photographic apparatus of the foldable type in which, when in preparation for photography, a front housing carrying a photographic objective lens system together with a focusing mechanism therefor is moved away from a rear housing to form an exposure chamber for a sensitive material loaded in the rear housing. When the apparatus is rearranged to a folded position, the front housing is brought into compact relation with the rear housing. Since a distance-measuring device is located in the rear housing, there is provided an electrical channel for establishing electrically operative connection between the focusing mechanism and the distance measuring device as arranged along a path between the front and rear housing which remains substantially unchanged in length during the erecting and collapsing operation of the apparatus.
