Abstract

PURPOSE: To variably set ON or OFF time by providing a memory in which time data are set and a means of comparing these with clock data and performing their coincidence detection.
CONSTITUTION: A coincidence detection circuit 13 sets a set priority type flip-flop 14 for time control when the data of all the digits of a time memory 12 coincide with clock circuit output and resets the flip-flop 14 when only the digits selected by external input coincide with the clock circuit output. In details, an exclusive-NOR circuit 15 outputs a 1-level signal when the respective 1-minute. 10-minute, hour- digit data of the clock circuit 11 and time memory 12 coincide. A selection switch 16 varies the ON time by selecting the digits to be compared. Here, when the external switch 16 is connected to the 1 level, the timer goes ON and after 10 minutes it goes OFF. When the switch 16 is connected to the 0 level, the timer goes OFF in one hour after timer ON.
