MODULAR MULTI-PARTITION CAMERA FOR MAKING MICROFICHES

摘要

A step wise drive system is mounted on a plate with a flat upper surface, in a light proof environment. The drive system drives a carriage via a motor actuating an endless screw which co-operates with the runner nut connected to the carriage. At the other end, the carriage comprises a motor which in turn co-operates with an endless screw acting on runner nut. The runner nut bears lateral slides connected to a film holder unit. Finally, the film holder unit is movable in a sliding fashion on a rail connected to the carriage. In this way, the film holder unit is connected to the second runner horizontally in X and Y directions and free vertically relative thereto. It can therefore slide on the upper surface of the plate with a dry fit, permitting excellent positioning of the microfiche for taking shots.
