Illustrated is a system for conveniently integrating facsimile scanning and printing functions into an electrographic copier system, with efficient use of space and other potential cost advantages.

The basic copier system (Fig. 1) comprises a translatable document holder (glass) 1 and an electrographic image recording drum 3, having rotational motion coordinated with translational movement of the document glass. The copying system also includes optics represented by lens 5 and a not shown source of noncoherent light, which illuminates the document during its translational movement. The light scattered from linear image segments on the transversely translating document is collected by the lens, and imaged on corresponding linear segments of the transversely rotating drum 3.

The facsimile related functions of document scanning and signal controlled printing are provided by a modulatable laser 7 and optical deflection, positioning and detection elements. The laser beam 9 is directed to a 15-sided rotating mirror 11 by fixed compound mirrors 12. Mirror 12 is positioned out of the deflection range of the rotating deflection mirror 11 so as not to interfere with the deflected beam. Motor 17 which drives the rotating mirror 11 is coupled to or coordinated with the drive impetus of the document glass 12 and recording drum
3. The deflected beam 9a is directed as a swept flying spot to the recording drum or to the document glass, depending upon the position of mo...
