Abstract

PURPOSE: To simplify the constitution and to increase the reliability, by outputting the strobe signal corresponding to each key switch with a suitable time interval, even if the depression signal corresponding to different key switch is detected one by one in the scanning period continuous tentatively.
CONSTITUTION: The first output detection means 8, 10 responds only to the final key operation output as to each key in the output of the multiplexer 2 to output the first output detection signal. First FF12 responds to the key operation output from the multiplexer 2 and it is set and reset with the period end signal made every end of the scanning to a series of key switch. The second FF13 responds to the key operation output to read in the output of the first FF12 and to output it and it is reset with the end signal of the above period and compulsively set at the said first output detection signal. The third FF15 is reset with the reset output of the second FF13.
