ABSTRACT:
Optical printhead for hard copy printers and copiers. The printhead includes a fiber optic lens array having a reinforcing and locating bar permanently bonded to the side and exact center of the lens. The bar has a dimension parallel to the axis of the fibers which is much more accurate than the length of the lens along the same axis. Centering of the lens array is easily and accurately accomplished by centering the bar. The bar also stiffens and straightens the lens array to maintain desired focal characteristics. The printhead also includes an accurately dimensioned mounting plate which is used to attach the printhead to the printer. A stress relieving structure is used to support the electronic circuitry and LED's in the printhead from a rigid heat sink.
