Apparatus for handling sheets for microfilming or other similar recording
Abstract:
An exposure table (20) included in an apparatus for handling sheets for microfilming or other similar recording is provided with slots (28) open through the table surface (27) facing the camera (14). Sheet drivers (22) run in these slots for feeding a sheet stepwise to the exposure table, said drivers being fastened to conveyor belts (21) running in channels (26) below the table surface (27). The conveyor belts have preferably a feed direction that forms a small angle (v.sub.1) with a guide ledge (23) along one table edge extending in the conveyor direction. Moreover, the exposure table is preferably provided with means (29, 30) for sucking by vacuum each sheet firm on the exposure table surface.
