Abstract

A transport device for a microfilm passage camera has a document supply device, and a transport device for further transporting a document in a camera and/or a document discharge device. Each of the document supply device and document transport device have a plurality of rotary members, a plurality of rings arranged so that each of the rotary members abuts against a respective one of the rings, a plurality of transporting rollers arranged so that the rings are mounted in groups on the transporting rollers, a lower guiding sheet limiting from above a document passage and provided with a plurality of perforations through which the rings extend into the document passage. The transporting rollers are driveable with a speed corresponding to filming of a document in the filming station.
