Abstract
In a scanning circuit having a plurality of cascade-connected unit circuits driven only by direct current, each unit circuit consisting of at least a pair of polarity inverting circuits, a train of output pulses shifted by a constant delay one after another depending upon the delay time proper to the unit circuits, are derived from the unit circuits by applying an input pulse to the first stage of the scanning circuit.
