ABSTRACT:
A plurality of photoconductive cells are each formed on an insulating substrate to extend in a straight line. The photoconductive cells are divided into m groups, each consisting of n cells, which is connected at one end to a common electrode, and corresponding ones of the photoconductive cells of the m groups are connected to individual select electrodes, respectively. By turning ON group select switches in a sequential order, the common electrodes are connected to a power source one at a time and, by sequentially turning ON individual select switches, the individual select electrodes are connected to a load one at a time. The common electrodes are grounded via grounding switches which operate reversely from select switches connected to the common electrodes. The individual select electrodes are grounded via grounding switches which operate reversely from select switches connected to the individual select electrodes. The resistance value of the load is selected sufficiently smaller than the composite resistance value of the photoconductive cells connected in parallel to the load when one of the group select switches and one of the individual select switches are both in the ON state.
