Abstract
Optical scanning apparatus is disclosed wherein a plurality of reading heads are mounted on a rotating support, and a light source directs light through an optical beam switching means which rotates about an axis colinear with that of the support but at half the rotational speed, whereby the reading heads are caused to be successively operational in turn over a given segment of each revolution of the support, which has a linear transnational movement relative to image-bearing subject(s) to be read.
