Abstract

The projector has a console with its top surface forming a viewing screen. Inside is a lamp and optical system. The microfilm cassette is loaded into a front compartment. This front panel also locates the control knob. The cassette has two cylindrical drums (1,2) joined by two flat surfaces (5,6). These are continuous with the drums and provide a space (3,4) for the microfilm (10) and also have a transparent opening (7). The microfilm is stored on a spool inside one drum and is wound onto another spool in the other drum through splines (8,9) inside each spool.
