<P>PROBLEM TO BE SOLVED: To provide a circuit comprising a smaller number of elements. <P>SOLUTION: The state detecting circuit comprises: a counter circuit 11a for counting a series of first command signals relating to the start of operation control; a second counter circuit 11b for counting a series of second command signals relating to the end of operation control; a counter match detection circuit 12 for detecting a match between count values in the counter circuits 11a and 11b; and an RS flip-flop circuit 13 that is set by the first command signal and is reset when the counter match detection circuit detects a match. The counter circuits 11a and 11b include a binary counter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
