Abstract
PURPOSE: To perform setting of the current time and setting of engaged time by supplying the signal which advances 1 count to an hour-minute counter through operation of a time setting key.
CONSTITUTION: When a key 9 is operated to U side or D side of the figure, the output of a frequency dividing circuit 4 is inhibited and a minute counter 6 is advanced by 1 count by the pulse at the differentiated leading edge, but a frequency dividing circuit 3 is reset by the same leading edge and therefore a flip-flop circuit 14 is not set until 1 second elapses. Because of this, no count pulse enters the counter 6 and therefore the counter (b) does not advance. When 1 second elapses, the counter 6 advances at each 1/20 second. In this way, the counter is fast fed up to the neighborhood of the minute value desired to be set and the operation of the key 9 is once stopped. When it is operated again, the counter 6 advances by only 1 count unless the key is kept pushed for more than 1 second and therefore the counter may be set easily at the required minute value.
