Abstract
A copier provides output signals corresponding to subject matter on material being copied. The copier includes a light source which provides light pulses that impinge upon the material. The material provides light pulses to a light sensitive sensor in accordance with the subject matter on the material. The sensor provides electrical pulses on a one-for-one basis with the received light pulses from the material. An output circuit provides the output signals in accordance with the electrical pulses from the sensor.
Claims7
Apparatus for providing output signals corresponding to a copy comprising a first laser emitting a beam of light, a mirror having a plurality of faces is spacially related to the first laser so that the light beam is reflected by the mirror when it is rotating in a manner so as to perform a scanning operation, means for rotating the mirror at a predetermined rate, image locator means spacially related to the copy and to the mirror for providing control pulses in accordance with the scanning of the light beam, a second laser spacially related with the first laser and the mirror and connected to the image locator means provides pulses of light which strike the surface of the mirror at the same point that the light beam strikes and is reflected therefrom to impinge upon the copy, light sensitive means spacially related to the copy for receiving pulses of light from the copy and providing electrical pulses on a one-for-one basis with received light pulses, and means connected to the light sensitive means for providing the output signals in accordance with the electrical pulses from the light sensitive means.
