There are provided a frequency divider for dividing the frequency of the frequency signal produced by an oscillator, a counter for counting the number of the frequency divided fundamental signal, an input circuit for prestoring a time to be announced in a memory device so as to operate an alarm device, a comparator for comparing the time counted by the counter with a preset time, an input circuit supplied with a message so as to display the message concurrently with the operation of the alarm device, a character memory device for storing the applied message, and a display device for displaying the stored message. The content of the counter is compared with the time to be announced preset in the memory device. When a coincidence holds a buzzer is operated and at the same time a predetermined message preset in the character memory device is displayed on the display device.
