JPH0548696A - Clock device of automobile telephone - Google Patents

Abstract

PURPOSE:To automatically express the time display of a clock device in an automobile telephone in terms of spot time so as to display it through the use of country code information transmitted from the base station of the automobile telephone. CONSTITUTION:Input time and the country code which is transmitted from the base station are inputted in an input circuit 11 and a clock circuit 12 displays time in a display part 13 in accordance with succeeding time change. The country codes transmitted from the base station of the shifted destination areas are detected in the input circuit 11 so as to be transmitted to a compensating circuit 14 and the compensating circuit 14 expresses time display in terms of spot time from the information and initial time information so as to display it in the display part 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timepiece device for a car telephone used for mobile communication.

[0002]

2. Description of the Related Art FIG. 3 shows a block configuration of a conventional clock device for a car telephone. In FIG. 3, 21 is an input circuit, 22 is a clock circuit, and 23 is a display section. Next, the operation of the above conventional example will be described. When the time information is input to the input circuit 21, the clock circuit 22 updates the time information as the time changes, and displays it on the display unit 23. As described above, in the conventional car telephone clock device, by inputting the time, the time corresponding to the change in the time thereafter can be displayed.

[0003]

However, in the above-mentioned conventional clock device for a car telephone, only the input time and the time change after that are taken into consideration, so that the car is moved between places having a time difference like a car telephone. In this case, there is a problem that the local time at the place where the car telephone exists and the time displayed by the clock device are different. The present invention solves such a conventional problem, and an object of the present invention is to provide a timepiece device for a car telephone capable of automatically correcting the time difference effect.

[0004]

In order to achieve the above object, the present invention uses a country code sent from a base station in which a car telephone exists to determine an initial input time and a country code of the input area. Therefore, the local time in the area where the mobile phone is used is calculated and displayed. Further, in order to emphasize that the local time is displayed, a character or character string indicating the local time is also displayed in the vicinity of the time display.

[0005]

Therefore, according to the present invention, the local time can be automatically displayed by using the country code.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of a timepiece device for a car telephone according to an embodiment of the present invention. FIG. 2 shows an example of the display method of the display unit in the embodiment of the present invention. In FIGS. 1 and 2, 11 is an input circuit, 12 is a clock circuit, 13 is a display unit, 14 is a correction circuit, 15 is a character (or character string) that emphasizes the local time, and 16 is a time display. .

Next, the operation of the above embodiment will be described.
In FIG. 1, at the same time as the time information is input to the input circuit 11, the country code information of the base station at that location is also automatically input. After the input, the time change is converted into the time in the clock circuit 12, and the time is displayed on the display unit 13. Further, the country code of the base station in the area where the car telephone is used is automatically detected by the input circuit 11, the local time is calculated by the correction circuit 14, and the corrected time is displayed on the display unit 13. At that time, as shown in FIG. 2, not only the time (local time) display 16 but also a character (or a character string) that emphasizes the local time is displayed on the display unit 12 at the same time. The country code is one of the pieces of information that is always sent from the car telephone base station.

[0008]

As is apparent from the above embodiment, the present invention enables the local time to be converted by using the country code sent from the base station in the area to which the timepiece device of the automobile telephone is moved. Therefore, there is no need to calculate an unnecessary local time, and it is possible to know the time surely quickly.
