Abstract
PURPOSE:To clearly inform an operator of the alarm setting even in the darkness by lighting a lamp for a fixed time utilizing an ON signal which is inverted by the ON operation of an alarm setting switch. CONSTITUTION:A time reference signal of an oscillator 2 is used to display the time on an indicator section 10. An alarm time is set by a setting circuit 12 and stored in a memory circuit 14. The time stored in composed by a coincide circuit 16 and set with a alarm setting switch 18. At this point, signals of the switch 18 is turned to H from L and inputted into an alarm setting circuit 24 comprising an AND gate 20 and a time limiting circuit 22. A signal with a fixed pulse width is applied to a transistor (TR) 26 to light a lamp 28 for a fixed time. When the current time coincides with the alarm time, the circuit 16 transmits a signal of H to a gate 20 to generate an alarm sound in a speaker 32 through TR 30. With the switch 18 off, the signal is turned to L from H to release the circuit 24.
