Production of photocopies ready forstorage - has unexposed space left between images reproduced on copy strip to allow separation

摘要

The system is for production of photo copies ready for storage in which original materials attached to a film strip are copied onto a strip of light sensitive copying material (1) to produce a series of images on the copy material which are then cut to size has the copy material strip moved forward by an amount sufficient to give a new copy surface between exposures and leave an unexposed section between images to allow holes or perforations to be made in the completed copy for easier storage by a device at right angles to the flow direction. The area free of picture material (4) is dark or coloured.
