Abstract

An electrophotographic copier is provided with a reciprocable copy board. An illuminating lamp is located between a pair of spaced frame members which have rails for guiding the copy board. An improved reflector for directing light from the lamp toward the copy board is formed as a single, unitary structure including a rearwardly-extending ledge directly and rigidly supporting the lamp on the ledge at a fixed, predetermined position and orientation with respect to the reflector such that relative adjustments between lamp and reflector are eliminated.
