A voice signal is output from the voice synthesizing circuit 10 based on the voice data, and the sounding device 11 voice-reports the city name, date and time of the home city based on the voice signal (routine).

In the untimed mode, when the time switch 7 is operated while the time of the city other than the home city is displayed on the display unit 4, the control circuit 8 resets the timer circuit 6 and the storage circuit 5 The home city number is read from, and the time difference corresponding to this number is read from the time difference storage circuit 3. Then, the date and time of the home city are calculated from the time difference and the time counted by the clock circuit 2, and the date and time are displayed on the display unit 4 together with the city number of the home city. At the same time, a signal is also output from the control circuit 8 to the audio data storage circuit 9, and based on this signal, audio data for audio notification of the city name, date and time of the home city is read and output, A voice signal is output from the voice synthesizing circuit 10 based on the voice data, and the sounding device 11 voice-reports the city name, date and time of the home city based on the voice signal (routine).

By the above operation, when the timing switch 7 is operated in the timing disabled mode, the time of the home city is displayed on the display unit 4 and the notification circuit 12 gives a voice notification.

Next, the home city setting operation will be described with reference to the flowchart of FIG. When the selection switch 1 of a desired city (hereinafter referred to as the first city) is operated in the untimed mode, the control circuit 8 reads out the time difference corresponding to the city number of the first city from the time difference storage circuit 3. The date and time of the first city are calculated from this time difference and the time measured by the time counting circuit 2, and the date and time are displayed on the display unit 4 together with the city number of the first city (routine). If no operation is performed after this display, for example, the city name, date and time of the first city is announced by the notification circuit 12 after 0.5 seconds. When the selection switch 1 of the city (hereinafter, referred to as the second city) is operated, the control circuit 8 compares the city numbers of the first city and the second city, and if they match, the city number of this city is determined. It is stored in the memory circuit 5 as a home city. At the same time, the time difference corresponding to this city number is read out from the time difference storage circuit 3, and the date and time of the home city is calculated from this time difference and the time measured by the clock circuit 2, and the result is sent to the voice data storage circuit 9. A signal is output, based on this signal, voice data for voice notification of the city name of the home city, date and time is read out and output, and a voice signal is output from the voice synthesis circuit 10 based on this voice data. Based on the output voice signal, the sounding device 11 voice-reports the city name, date and time of the home city (routine).

If the first city and the second city do not match,
The time difference corresponding to the second city is read from the time difference storage circuit 3, and the date and time of the second city is calculated from this time difference and the time counted by the clock circuit 2, and this date and time is calculated as the second city. It is displayed on the display unit 4 together with the city number. At the same time, a signal is output from the control circuit 8 to the voice data storage circuit 9, and voice data for voice notification of the city name, date and time of the second city is read and output based on this signal. A voice signal is output from the voice synthesizing circuit 10 based on the voice data, and the sounding device 11 voice-reports the city name, date, and time of the second city based on the voice signal (routine).

By the above operation, the selection switch 1 of the desired city is operated, and the selection switch 1 of the same city is operated again before the city name, date, and time of this city are announced by voice. It is stored in the memory circuit 5 as a city.

EFFECTS OF THE INVENTION According to the present invention, an arbitrary city can be set as a home city by operating the selection switch a plurality of times within a fixed time, and the time of cities other than the home city can be displayed on the display unit. Even if it is displayed, it will switch to the time display of the home city after a certain period of time, so you can set any city as the home city very easily without adding a new switch, and the time of this home city is always displayed. Can be confirmed. Therefore, for example, if you set your own city as your home city, you can know the time in your own city without operating the selection switch, and at the same time, you will be able to know the time in your own city. You will no longer read the time of the city as the time of your city without noticing it.

Also, by notifying the time of the home city by operating the timing switch in the untimed mode,
You can easily check the home city time aurally without adding a special switch. Therefore, in a world clock with many selection switches, the trouble of searching for the selection switch of the city set as the home city is eliminated, which is convenient especially in a dark place.
