Abstract

PURPOSE:To enable to decide the main scanning speed surely, by detecting an agreement between the old phase signal and the new phase signal by means of the element which delays the signal. CONSTITUTION:The phase signal applied to terminal 1 is applied to delay circuits 11-16 consisting of shift registers through waveform shaping circuit 2. In case of three kinds of phase signal of 1Hz, 1.5Hz, and 2Hz, the delay time of each delay circuit is set to 1/6 seconds. Then, scanning speeds for 1Hz, 1.5Hz and 2Hz are detected at terminals 61-63 by operating AND of output S0-S6 of delay circuits by logical operation circuits 21-23.
