Abstract

PURPOSE: To perform the operation of a potentiometer by emitting light on a photo conductive film, when a pair of the element patterns providing a resistive film and an output electrode layer is placed in a row at the both sides of the photot conductive film, a voltage is applied across the both resistive films in series connection, and an output voltage is picked up by connecting the both output electrodes.
