Abstract

PURPOSE:To urge to regulate at the original set time, by operating the built-in alarm mechanism when an external regulator switch is manipulated, and waring the user the change of the internal set time. CONSTITUTION:When an external regulator switch 2 is made to conduct, AND gate 5 takes AND of voltage level 1 at point (a) and 1 Hz signal from frequency dividing circuit 3, and inputs it into an external regulator circuit 1. A transmission gate (TG) 7 is made to conduct by the voltage level 1 at point (a), and the output signal of AND gate 6 is inputted into the base electrode of a driver 10, so that a speaker 11 is driven. The output signal of AND gate 8 is in the relation to drive a speaker 10 through a signal from a counter for setting an alarm. Thus, driving speakers with pulses having certain freuency and period at the time of external regulation, the change of the internal set time is noticed.
