Abstract
An arrangement for the line by line scanning of a document has a line array of individual light sensor elements each of which is characterized by a gas discharge chamber limited on one side by a cathode and on the opposite side by photoconductor layer carrying a transparent and a non-transparent signal electrode. The signal electrodes are common to all the sensor elements in the line array, extend parallel to each other, and are connected to a differential amplifier to eliminate switching transients and dark signals from the information signal.
