ABSTRACT:
The camera case is intended for microfilm cameras. In order to permit filming copy switching directly from punch cards to continuous film strip, the housing of the camera features two film reel holders mounted on either side above the punch card holder. Surmounting this, provision is made for a vertically adjustable film holder element. The punch card holder element is constructed from, and arranged as the vertical positioning path of the film holder element. Two further embodiments consist in the fact that the copy holder element is provided with a film feed channel bounded on its upper side with a suction plate and on its lower side with a shutter, or that within the housing provision is made for two film reel holders capable of joint transverse displacement in relation to the copy conveyor path and/or the optical system.
