DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device with a world clock.

[0002]

2. Description of the Related Art When a region displayed on a display device is selected, a display device with a world clock of this kind automatically displays a three-letter code of a representative city of the region together with a mark indicating the region. In addition, three-letter codes of a plurality of cities belonging to the same time zone can be sequentially displayed by operating the area selecting means.

[0003]

However, such a display device with a world clock has the following problems. Just by selecting a region, a three-letter code that is irrelevant to you will be displayed contrary to your will. It is troublesome to set three digits of a related three-letter code (that is, to be displayed). If only the city code is set and the region selection (time difference set) is forgotten, the city code and the time difference will be mismatched.

[0004] Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a display device capable of performing data set quickly.

[0005]

In order to achieve the above object, a display device according to the present invention comprises: a world clock device for automatically correcting the time difference between a plurality of regions in the world; a region selecting device for selecting a region; Selection means for selecting any alphabet of at least three digits, display means for displaying the selected alphabet and a mark representing the selected area, and three letters of at least one city belonging to one of the plurality of areas A storage means for storing a code, and specifying a region, selecting a three-letter code stored only when the highest-order character of the three-letter code stored at least at the top of the three-digit alphabet is selected. And reading means for calling one of them and displaying it on the display means.

[0006]

According to the present invention, when the first character of a city is designated together with the selection of a region, the remaining two digits are automatically displayed. Also, setting the city code automatically corrects the time difference.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a display device according to the present invention. In the figure, 21 is a world clock device for automatically correcting the time difference between a plurality of regions in the world, 22 is a region selecting device for selecting a region in the world, 23 is a selecting device for selecting a three-digit alphabet, and 24 is a selecting device. Display means for displaying the selected alphabet and a mark indicating the selected area; 25, storage means for storing three-letter codes (city codes) of one or more cities belonging to one of a plurality of areas; Only when a certain region is selected and at least the highest-order character of the three-letter code stored at the highest position of the three-digit alphabet is selected, a specific one of the stored three-letter codes is called and displayed. Control means for comparing the selected alphabet with the stored three-letter code; and 28, the displayed data. Is an imprint means that imprint the part of the film.

FIG. 2 is a rear view of the camera showing a configuration according to an embodiment in which the display device according to the present invention is mounted on the camera. In the figure, 1 is a camera body, 2 is a back lid supported by a hinge 1a, 3 is a display window, 4 and 5 are area selection switches, 6 and 7 are switches for selecting a three-digit alphabet, and 6 Is an adjust switch for selecting a character, and 7 is a select switch for selecting a digit. Reference numeral 8 denotes a display mode switch.

FIG. 3 is an enlarged view showing details of the area 2a of the back cover 2 in FIG. In the figure, reference numeral 11 denotes a world map representing time difference and a label on which the representative city name of each region is printed, 12 denotes a liquid crystal display device, 13 denotes a display unit for displaying date and time data or a three-digit alphabet, 14 Is a display unit for displaying a regional mark (region number).

Table 1 below shows a list of cities belonging to each time zone stored in the storage means 25 and their three-letter codes.

[0011]

[Table 1]

Next, the operation and operation of the display device configured as described above will be described. Now 1991 in Japan time
8:50 am on October 24, 2008. FIG. 4A shows that the display unit 14 in the liquid crystal display device 12 has a Japanese region number “20” and the display unit 13 has a date “'91 10 24”
And are displayed. Each time the display mode changeover switch 8 is pressed, the date and time display shown in FIG.
After the character display shown in (c), the display returns to the display shown in FIG.

The character "AAA" appears as the earliest state. In FIG. 4B, the area selection switches 4 and 5
When the area is set to "12" by the operation of (1), the time difference is corrected and the display changes to the display shown in FIG.

Next, character selection will be described with reference to FIG. In FIG. 5E, the area number "12" and the character "AAA" are displayed. Here, when the first digit is set to the correction mode by pressing the select switch 7, the digit of the correction mode blinks as shown in FIG. Next, when the adjust switch 6 is pressed to set the first digit to "B" as shown in FIG. 5 (g), the second and third digits are simultaneously changed to "C" and "N", respectively. This is a Barcelona code having the letter "B" of the area number "12" at the top.

Subsequently, the adjust switch 6 is pressed,
When "P" is set as shown in FIG. 5H, the display becomes "PAR (Paris)". Next, select switch 7
Is pressed to release the correction mode and fix the display "PAR" as shown in FIG. 5 (i). Or select switch 7
By operating the adjust switch 6, "PPM (characters other than the city code)" is set as shown in FIG.

In FIG. 5 (g), select switch 7
Is pressed to fix "B" as shown in FIG. 5 (k), and the second digit is set to the correction mode. Next, when the adjust switch 6 is pressed and "R" is set to the second digit as shown in FIG. 5 (l), "U" appears automatically in the third digit, and the display is "BRU".
(Brussels) ". The following is shown in FIGS.
This is the same treatment as.

In FIG. 5 (f), when the select switch 7 is pressed to fix "A" as shown in FIG. 5 (m) and the adjust switch 6 is pressed to set "M" to the second digit, " AMS (Amsterdam) "is displayed. The following is the same procedure as in FIGS. 5 (i) and (j).

Next, the display of the time and the area number of the area to which it belongs will be described with reference to FIG. FIG. 6 (p)
Is Japan's regional number "20" and city code "TYO"
And are displayed. When the display mode changeover switch 8 is pressed to set the date and time mode, the time in the area is displayed as shown in FIG. 6 (t). FIG. 6 (p)
In FIG. 6, "LAX" is displayed by operating the select switch 7 and the adjust switch 6 as shown in FIG. Next, the select switch 7 is pressed to fix "LAX" as shown in FIG. 6 (r), and at the same time, the area number is automatically changed to "3". Here, when the display mode changeover switch 8 is pressed to set the date and time mode, FIG.
The time of the area is displayed as shown in FIG.

In FIG. 5, "BCN" and "BRU" are displayed in alphabetical order as an example in the case where the alphabet is the same (a plurality of corresponding city codes) in the first digit display section 13. The order may be the frequency.

FIG. 7 is a flowchart showing the operations of FIGS. 4 to 6 described above in steps.

[0021]

As described above, according to the present invention,
If you specify the first character of the city along with the region selection, the remaining two digits will be displayed automatically, and if you set the city code, the time difference will be automatically corrected, so you can quickly set up the data An extremely excellent effect can be obtained.
