A copy camera, preferably configured to make enlarged prints from 35mm slides, operates in at least two different magnification modes for providing either a full frame or cropped reproduction of the slide on a film unit having an image area format that differs from that of the slide. Magnification change is accomplished by locating the slide and film unit at alternative corresponding object and film planes that are located at different predetermined image and object distances from a projection lens. An electromechanical logic system provides an indication to the operator of which magnification mode has been selected and automatically inhibits initiation of an exposure cycle if the slide and film unit are not in the corrected corresponding positions to provide a focused image of the slide on the film unit.

Variable magnification slide copy camera

A self-developing slide copier or printer configured to be supported on a support surface and operable for effecting distribution of a fluid processing composition between sheets of a self-developing film unit in response to manually withdrawing or pulling the film unit along a preferred exit path has its film receiving housing set at a predetermined angle on a support frame so that the preferred exit path will fall within a range of natural pull paths along which an operator most likely will pull the film unit to withdraw it from the housing. The printer is also provided with multiple timers for separately timing a predetermined imbibition period for each of a plurality of sequentially processed film units.
