Abstract
Abstract A detecting device capable of being strapped around and positionally mounted on a variety of sizes of document guide channels in a self-adjusting manner. The light transducing units of the devices can be prealigned and configured to face each other through apertures in the guide channel in such a manner as to be relatively impervious to ambient light.
