Abstract

PURPOSE:To attain a high-speed scan with a simple constitution, by using an optical gate array element containing a light transmitting part which electrically shifts and carries out the scan. CONSTITUTION:The light given from a light source 1 is irradiated onto an optical gate array element in a belt form, and this irradiated light passes through onoy the light transmitting part of the element 3 to be irradiated to a transmitting original 4. At the same time, the light reflected from the original 4 is led to a photocell 6 through the above-mentioned light transmitting part. This light transmitting part shifts successively to perform the scan, and the information written on the original 4 is decomposed into picture elements to be delivered from the cell 6 in the form of a time series signal that shows the concentration of the picture element. The scan of the light transmitting part of the element 3, that is, an operation by which the voltage is applied between the adjacent electrodes with a successive change given to the positions of the electrodes can be carried out in an electronic way by means of a driving circuit 5 including a shift register, etc.
