An example of the sounding device 11 is shown. The selection switch 1 uses a touch switch, and the display unit 4 uses a liquid crystal panel.

Next, the operation will be described.

First, a description will be given according to the flowchart of FIG. The clock circuit 2 measures the time of the reference city every second. Further, the time of the home city stored in the storage circuit 5 is normally displayed on the display unit 4 (routine).
Here, when the display unit 4 is switched to a display other than the time of the home city, the timer circuit 6 operates, and when a certain time is measured, a signal is output to the control circuit 8. In response to the signal from the timer circuit 6, the control circuit 8 outputs a signal for resetting the timer circuit 6 to reset the timer circuit 6, and at the same time, the home city number is read from the memory circuit 5 and the number is read out. Is read out from the time difference storage circuit 3, and the date and time of the home city is calculated from the time difference and the time counted by the clock circuit 2. The date and time are calculated as the city number of the home city. Together with this, it is displayed on the display unit 4 (routine).

By the above operation, even when the display unit 4 switches to a display other than the time of the home city, it switches to the display of the time of the home city after a fixed time.

Next, the voice notification operation in the untimed mode will be described with reference to the flowchart of FIG. When the timing switch 7 is operated while the time of the home city is displayed on the display unit 4 in the timing disabled mode by the timing lock switch (not shown), the control circuit 8 outputs a sound. A signal is output to the data storage circuit 9, and the voice data storage circuit 9 reads and outputs voice data for voice notification of the city name, date and time of the home city. A voice signal is output from the voice synthesis 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 synthesis 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.
Is displayed at the same time and is sounded by the notification circuit 12.

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 will be 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. The signal is output. Based on this signal, voice data for voice notification of the city name, date and time of the home city is read from the voice data storage circuit 9 and output, and based on this voice data, the voice synthesis circuit 10 outputs a voice signal. Is output, and the sounding device 11 gives a voice notification of the city name, date and time of the home city based on the voice signal (routine).

When 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 second time difference is determined by the time difference and the time counted by the clock circuit 2. The date and time of the city are calculated, and the date and time are displayed on the display unit 4 together with the city number of the second city. 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 synthesis 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.

In the above embodiment, the selection switch is provided for each major city, but the invention is not limited to this, and there is only one selection switch, and each major city is sequentially selected and displayed each time it is operated. May be used for.

EFFECTS OF THE INVENTION According to the present invention, even if the time of a city other than the home city is displayed on the display unit, the display returns to the time of the home city after a certain period of time, so the time of another city is set to the time of the home city. There is no risk of reading it by mistake, and you do not have to operate the selector switch to call the home city time, and if you set your own city as the home city, you can use it as a normal clock. You can In addition, by switching to the time display of the home city by operating the time switch in the untimed mode, and by notifying the time by voice, the time of the home city can be quickly set by a simple operation without adding a special switch. It can be confirmed audibly and visually. Therefore, in a world clock having 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.
