Abstract

PURPOSE:To surely detect and display data with a simple configuration, by displaying demodulated data only by taking the data into a shift register only when prescribed 2-phase level codes, such as track No., etc., are inputted. CONSTITUTION:A signal including 2-phase level codes reproduced from a signal input terminal 11 is shaped in waveform at a waveform shaping circuit 12, and supplied to a 2-phase level code demodulating circuit 14 through an AND circuit 13. Moreover, composite synchronizing signals are separated from input signals at a vertical synchronizing separator circuit 18, and the synchronizing signal is added to an RS latch circuit 20 through a time constant circuit 19, and then, inputs of signals into the circuit 14 are prevented for a prescribed period. During this period, the circuit 14 reproduces a clock signal C and outputs demodulated data of track No., and then, inputs the data of track No. into a shift register 15 by means of the signal C. Then, the data of track No. is supplied to a display circuit 17 by the pulse from the 1st output terminal Q1 through a D latch circuit 16 and the data are displayed.
