ELECTROPHOTOGRAPHIC IMAGE RECORDING METHOD AND APPARATUS

摘要

An electrophotographic method and apparatus for recording micrographic images permanently on a transparent substrate, in which plural planar reusable electrophotographic plates are mounted for stepwise movement sequentially along a path for a cycle of successive functional operations, namely, each plate being sequential charging exposure to form a latent charge image, toning the resulting charge image toned, drying the toned image and contact transferring the toned imaging to a transparent substrate and preparing the plate for reuse. The apparatus includes a rotor for mounting the plates about its circumference and a framework for mounting the functional stations positioned about the rotor circumference in operative condition relative the plates mounted on said rotor. A stepping motor or other incremental-type drive drives the rotor in a programmed movement. The framework and rotor are surrounded by a light-tight housing. A suitable aperture is provided in the housing to enable an exterior projector to direct a micrographics image to the charged photoconductive surface of the plate. A transfer station includes feed, guide and storage as a self contained unit, including both heating and pressure units for laminating the plate carrying the toner image and the transparent substrate. The completed transparency is mounted on a storage card.
