Abstract
PURPOSE: To obtain a digital electronic watch which can be used as a timer easily, by performing the end and the start of the operation of plural timers in series and reporting the timer operation end time with alarm tone.
CONSTITUTION: For example, in case that a user has something to do 45 minutes after and has something to do after 50 minutes after, 45 minutes and 5 minutes are set to first timer 1 and second timer 2 respectively. At the timer start, AND gate 21 is opened, and first timer 1 starts subtraction operation, but second timer 2 does not perform subtraction operation. After elaspe of 45 minutes, when the output terminal of minute timer 5 becomes 0, second timer 2 starts subtraction operation automatically, and simultaneously, alarm tone is emitted from buzzer 19 for a prescribed time. A 0 detection signal is outputted from detection circuit 3 5 minutes after from the operation start of second timer 2, and alarm tone indicating the operation end of second timer 2 is generated.
