Read/write bar for multi-mode reproduction machine

Abstract From the Canadian patent

A multi-mode reproduction machine or copier incorporating a full width read/write bar having at least one linear array of LEDs for selectively scanning a document original in a read mode or exposing the copier photoreceptor in a write mode. An array of lens elements is provided for focusing the LED array on both the document original and the photoreceptor the, read/write bar and lens array being combined in a unitary structure selectively movable between read and write positions. In an alternate embodiment the read/write bar and lens array is disposed in a fixed position to permit selective reading of the image developed on the photoreceptor or writing of images onto the photoreceptor.
