Abstract

PURPOSE: To let the point when display contents become zero and the ON-OFF operation point of a timer coincide by automatically displaying the specified left time of second unit in the display part of hour or minute unit in a timer or the like.
CONSTITUTION: Normally, a binary counter 9 is held reset and the current time of the hour and minute is displayed in a display part 17 by counting of a circuit 3. Timer time has been set and stored in a left time memory circuit 7. When the counter 9 is set by a switch S1, the hour and minute data in the circuit 7 are sent to the display part 17. When the left time becomes 1 minute or less, the contents of the memory parts 7a, 7b of the hour and minute become zero and that state is detected in circuits 8a, 8b, by the outputs whereof a gate 5 is opened and the second data of the second memory part 7c is supplied to the display part 17. When the left time of second unit becomes zero, alarming is accomplished in an alarm part 13.
