ABSTRACT:
An optical printhead for use in electrophotographic copiers and printers. The printhead is constructed of a linear LED array and a linear fiber optic lens mounted above the LED array. The lens mounting structure provides a floating support for the lens at the two end regions of the lens. The floating mount provides for temperature-induced dimensional changes and prevents distortion and stress in the structure. The end mounted supports permit relative movement betweeen the end regions of the lens and the LED array in two dimensions, but restrict movement in the third dimension.
