Abstract

An optical printer head for a recording apparatus which records an image on a photoconductive material is disclosed. The optical printer head confronts the photoconductive material. The optical printer head has a transparent substrate, a cathode unit for emitting electrons and an anode unit for receiving the electrons emitted from the cathode unit. The anode unit is formed of transparent conductive film and provided on the transparent substrate. A phosphor unit is provided on the anode. When the phosphor unit emits light resulting from impingement of electrons which are directed from the cathode unit to the anode unit, light emitted from the phosphor unit is transmitted through the transparent substrate and the anode. A grid is provided for attracting electrons from the cathode toward the phosphor unit. A lens is provided in the substrate for focusing the light emitted by the phosphor unit. An evacuated enclosure surrounds the cathode unit, the grid, the phosphor unit, and the anode unit.
