Tape or sheet recording media transport device - is for data processing machines and generates forces perpendicular to direction of movement

摘要

The transport device for tape or sheet recording media in data processing machines enables the medium to be free running at its edges and simultaneously gripped in a plane perpendicular to the direction of motion by rollers. This enables an ambiguous scanning of the medium, partic. of those carrying X-ray or electrostatic images scanned and transferred to a remote receiver. The image transmitter or developing unit can be combined with the recording device and warm air drying may be used with wet developing systems. Synchronised endless transport belts are arranged at both edges of the medium. Oppositely rotating rollers placed parallel to and above the belt and stretched across the full width of the medium to generate perpendicular frictional forces on the medium.
