ABSTRACT:
A line scanning, illuminating apparatus for use in an electrophotocopying machine. The apparatus includes a linear source of light, a hyperbolic reflector situated behind the linear light source, and a cylindrical lens located in front of the linear light source. The profile of the reflector is given by the equation: ##EQU1## wherein the x and y axes intersect at the center line of the reflector, and wherein B is a positive quantity on the x axis representing the distance between the center line of the reflector and a virtual image of the light source created behind the reflector, and wherein A is a negative quantity representing the distance between the center line of the reflector and the linear light source located in front of the reflector.
