Abstract

PURPOSE: To prevent characters from escaping under no restriction on programming by outputting an error signal when no high-level sprocket signal is inputted to a channel-signal and sprocket-signal synchronizing circuit.
CONSTITUTION: Signals CH1 to CHn from channel-signal sprockets are supplied via OR circuit 11a of input circuit 11 to decision circuit 13 and AND circuit 12a of channel-signal and sprocket-signal synchronizing circuit 12. One terminal of AND circuit 12A is supplied to sprocket signal SP and its output is supplied to decision circuit 13 via NOT circuit 12b. Timing signal TP is also applied to decision circuit 13, the output of which displays a skip error. The relations between each signal and the decision outputs are shown in the figure and when channel signals are read out on the basis of sprocket signals, its skip can be prevented perfectly.
