Abstract

A multi-function printer employing a linear array of lenslets for transmitting, when in the COPY mode, image rays from the image original being copied to the moving photoreceptor of a xerographic system. To scan the image original, the platen is moved past the scan point whereat the lens array optical path intersects the platen. For operation in a READ mode, a linear reading array of photosensitive elements is disposed to one side of the optical path between the lens array and the photoreceptor, the longitudinal axis of the reading array being perpendicular to that of the lens array. A prism is inserted into the optical path to intercept the image rays transmitted by the lens array from the platen and transmit the image rays to the reading array where the image represented thereby is converted to electrical signals or pixels. For operation in a WRITE mode, a linear writing array of LEDs is disposed to one side of the optical path between the platen and the lens array, the longitudinal axis of the writing array being perpendicular to that of the lens array. A prism is inserted into the optical path to transmit image rays emitted by the writing array in response to an image signal or…
