Transparency copier adapted from slide projector - having rotary cassette and camera with lens fastened to front directly in projection path

摘要

The transparencies to be copied are held in a rotary cassette (13) on top of a projector (10). Each slide (14) is dropped into the light path (at 27) to be photographed by a camera (11). The camera lens (17) is where a projection lens would normally be. Illumination for the transparency (14) is provided by the projector lamp (21) with associated reflector, condenser and heat filter system (22, 23, 24, 25, 26). The position of the camera (11) can be adjusted on the front of the projector (10) by a collar attachment (19). The camera (11) has a motor drive (18). The camera can easily be taken off the projector so that it can be used for normal slide projection.
