Description

[0001]
[Industrial application fields]
The present invention relates to a world time dial which is an inexpensive material and has a simple configuration and can instantly know the time of major cities in the world.
[0002]
[Prior art]
In recent years, internationalization has progressed in various industries, and communication with the whole world is frequently performed. And when making a telephone call or the like, it is necessary to grasp the time of major cities around the world based on Japan time.
[0003]
In accordance with the necessity, for example, a world clock described in Japanese Utility Model Publication No. 62-176780 has been proposed. This world clock has a clock mechanism with a world map centered on the North Pole attached to the dial. A dial for displaying the area is attached to the dial so that it can be rotated, and the pointer rotates according to the rotation of the earth. By doing so, the time of each country in the world can be understood.
[0004]
[Problems to be solved by the invention]
However, since the above-mentioned world clock has a clock mechanism, its price tends to be expensive.
In addition, it is usually necessary to recognize the time based on the city name, such as “Japan is X hour but San Francisco is what time”, but the world clock as described above uses the time as a reference to calculate the city time. Since it is something to grasp, there is a problem that the time of the city you want to know immediately cannot be grasped.
Furthermore, since the world map centered on the North Pole is not well known, the location of major cities is difficult to understand, and the function of the world clock may not be fully demonstrated.
[0005]
The present invention has been proposed to cope with such a situation, and an object of the present invention is to provide a world time dial which can understand the time of major cities in various countries of the world with a simple and inexpensive configuration.
