Abstract

PURPOSE:To display the time of a callee side by computing the difference in time of the callee side with a dial number and also computing the time of the callee side according to the difference in time and the present time. CONSTITUTION:A titled set provides a dial detection means 7 for detecting the pulse of the dial signal from a dial transmission part 3 and outputting an international code which expresses the country or the area of the callee side and an computing means 8 for computing the time of the country or the area of the callee side according to the international code from the dial detection means 7, etc. The computing means 8 has a table which shows the relation between the international codes expressing all the countries and all the areas of the world and Greenwich time. Thus, the time of the callee side can be displayed by computing the difference in time of the callee side according to the dial number and also computing the time of the callee side according to the difference in time and the present time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a telephone device suitable for displaying the country and time of a called party in the case of an international call or the like.

2. Description of the Related Art Conventionally, a telephone device having a display function uses an LCD (Liquid
id Crystal Display), etc., and is configured to display telephone charges, current time, etc.

Problems to be Solved by the Invention However, in order to display the time of the country or territory in which the telephone is installed, a telephone having the above-mentioned display function allows the calling party to Therefore, there is a problem that the called party may be bothered by calling late at night or early in the morning.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a telephone device that can display the time of the called party.

Means for Solving the Problems In order to solve the above problems, the present invention detects the country or region of the called party based on the dial number, calculates the time difference with the country or region of the called party, and calculates the time difference. The present invention is characterized in that the time on the called side is calculated and displayed based on the current time and the current time.

Function The present invention calculates the time difference of the called party based on the dialed number,
Since the time on the called side is calculated based on this time difference and the current time, there is an effect that the time on the called side can be displayed.

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a telephone device according to the present invention.

In FIG. 1, 1 is a dial key for dialing, 2 is a key detection means for detecting the operation state of the dial key 1, and 3 is a dial signal ( 4 is a mode switching means for switching between the calling mode and the called side time display mode; 5 is a mode selection switch for switching the mode switching means 4; , a central office line; 7 is a dial detection means for detecting the pulse of the dial signal from the dial sending unit 3 and outputs an international code indicating the country or region of the called party; 8 is an international code from the dial detection means 3; It is a calculation means that calculates the time of the country or region of the called party, and the calculation means 8 is
It has a table showing the relationship between international codes indicating regions and Greenwich Mean Time.

Further, 9 is a display such as an LCD, and 10 is a clock circuit that calculates the current time.

Next, the operation of the embodiment according to the above configuration will be explained.

First, when the mode changeover switch 5 is in the calling mode, the mode changeover means 4 connects the dial sending means 3 to the central office line 6.

In this case, when a dial number is input through the dial key 1, it is detected by the key detection means 2, and the dial sending means 3 converts it into a dial signal and sends it to the central office line 6 via the mode switching means 4. By sending this dial signal, the called party can be called and a conversation can be made.

On the other hand, when the mode changeover switch 5 is in the called side time display mode, the mode changeover means 4 connects the dial sending means 3 to the dial detection means 7.

In this case, when a dial number is input via the dial key 1, it is detected by the key detecting means 2, the dial sending means 3 converts it into a dial signal, and outputs it to the dial detecting means 7 via the mode switching means 4.

When the dial detection means 7 detects the international code from the dial signal and outputs it to the calculation means 8, the calculation means 8 calculates the time difference with the called party using a table showing the relationship between the international code and Greenwich Mean Time. By adding or subtracting the time difference from the current time on the clock circuit 10, the time on the called side is determined and displayed on the display 9.

Therefore, according to the above embodiment, when making an international call, the calling party can learn the time of the called party by setting the mode changeover switch 5 to the called party's time display mode. No more annoying phone calls late at night or early in the morning.

Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 2, the same reference numerals are given to the same components as those in FIG. 1.

In FIG. 2, 1, 2, 3, 6, 8, 9, and 10 are the dial keys, key detection means, dial sending means, office line, calculation means, display, and clock circuit shown in FIG. 1, respectively. , 7a is a dial number detection means for outputting an international code based on the dial number from the dial detection means 2, 11 is a memory for storing the number from the key detection means 2, and 12 is a redial switch.

In the above configuration, when a dial number is input through the dial key 1, it is detected by the key detection means 2 (2), and the key detection means 2 outputs this dial number to the dial number detection means 7a and also outputs it to the memory 11. Store.

When the dialed number detection means 7a detects an international code from the dialed number and outputs it to the calculation means 8, the calculation means 8 calculates the time difference with the called party based on a table showing the relationship between the international code and Greenwich Mean Time. By adding or subtracting this time difference from the current time on the clock circuit 10, the time on the called side is determined and displayed on the display 9.

Next, when the redial switch f12 is turned on, the dial number in the memory 11 is output to the dial sending means 3, which converts it into a dial signal and sends it to the central office line 6.

Therefore, according to the above embodiment (2), when making an international call, the time of the called party can be known by first dialing, and if the called party is not late at night or early in the morning, the redial switch 12 By operating the , you can call the called party without having to dial again.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention calculates the time difference of the called party based on the dialed number, and displays the time of the called party in order to calculate the time of the called party based on this time difference and the current time. It has the effect of being able to
