ABSTRACT:
A housing for a light emitting diode recording head used for linewise recording information on a photoreceptor in a recording apparatus is constituted by elongated extrusion molded base and cover sections held together in a unitary structure by injection molded and closure members. The cover section has opposed inclined side walls engaged at their diverging margins on the base section and defining at their converging margins an elongated slot for receiving the lens array of the head. Preferably, the cover section is formed of two identical subsections with their converging margins held apart by an inner leg on each end member to define said slot. The end members and/or the ends of the base section can carry projections to facilitate accurate mounting of the head in the apparatus. The inner surfaces of the cover section can be contoured to provide sealing surfaces for cooperation with a sealing bead of resilient material surrounding the electrical components within the head.
