Abstract

In the xerographic arts, the concept of up-datable image information storage with soft display capability to permit the operator or user to view the developed image before transfer thereof to the copy sheet is known. Also, the use of such stored images in a copier input precollation system. Both of these applications directly utilize the optical properties of the stored information existing in the form of an unfused toner pattern on a photoreceptor surface.

In the xerographic arts, the concept of up-datable image information storage with soft display capability to permit the operator or user to view the developed image before transfer thereof to the copy sheet is known. Also, the use of such stored images in a copier input precollation system. Both of these applications directly utilize the optical properties of the stored information existing in the form of an unfused toner pattern on a photoreceptor surface.

A system wherein the toner image on a photoreceptor surface is read out by a scanning laser beam could make electronic readout of such stored image infor- mation useful as, for example, in generating hard copy using a raster output scanner to scan and expose the photoreceptor of a xerographic machine in accordance with image signals derived from reading the stored image. In this system, a photordetector is used to sense reflected light from the scanning beam as modulated by the presence of a developed toner pattern.

A particular merit of the proposed image converter/display system would be its
