Abstract

A scanning electro-optical copying appts. uses a laser which emits a beam of coherent light which passes an acoustic optic modulator (2). A collimator (3) narrows the beam to a dia. corresp. to the analysis resolution required for the original document scanning. A bi-route deviator (4) alternately directs the collimated beam to the upper or lower sides of a frusto pyramidal mirror drum (5) driven by a motor (6). The beam thus performs alternative analysis and synthesis scans across respective ones of an original (7) and copy medium (8) fed in direction (F1, F2) orthogonal to the scan paths.
