Abstract

PURPOSE: To make it possible to predict the end of a timer, while having timer functions, by adoping a progamable logic array in a timer end detection unit and a timer end predicting time detecting unit.
CONSTITUTION: The output of a timer setting circuit 2 is set in a timer circuit 1 through AND circuits 14 and 15 so that the counting operations are accomplished at the latest until a set time. If it is detected by a detecting circuit 8-1 that the counted content of the timer circuit 1 is reduced to zero, the alarm circuit is operated. If a prediction time setting circuit for predicting the end of the counting operation of the timer circuit 1 is provided so that the predicted time is detected by a detecting circuit 8-2, an alarm circuit is driven by the detected output to inform the predicted time in alarm sounds. On the other hand, a programmable logic array is used in the detecting circuits 8-1 and 8-2 to constitute the same circuit block so that the predicted time detection specified can be easily programmed.
