In case the circuit 8 generates its output earlier after the adding process, the timer operations are started from the OFF start, whereas they are started from the ON start in case the circuit 9  is earlier. In these ways, a pattern judging circuit 10 generates its output so that the control of a device is performed by the circuit 10. Thus, it is possible to form the proper operation patterns.
