Abstract

PURPOSE: To facilitate discrimination whether the time being displayed is of real type or alarm type by accomplishing the specific display in an acoustic or optical method during the time while a digital display device displays the alarm time.
CONSTITUTION: The input switches of switches S1 to S7 are arranged to face the key input circuit 11 of a monocylic integrated circuit 1 for digital clock. The switch S1 is an alarm display switch which is turned on to display the output of an alarm counter 9 in a digital display device 2. The switch S2 is a sleeve display switch which is turned on to display only the unit of the digital display device. The switch S3 is a second display switch which is operative to display a second counter 6. When the switches S1 to S3 are not conductive, the display device 2 displays the output of an hour counter 7. When, on the other hand, the switch S1 is turned on so that the display device 2 displays the time which is generated by the alarm counter 9, a buzzer 3 is rung in response to the conduction signals of the switch S1 so that the discrimination between the real time and alarm displays may be accomplished
