[Problems to be solved by the invention]
However, since the symbol candidates displayed in a list on the symbol board cannot be displayed on one page on the display screen of such a small portable terminal device, they are displayed over a plurality of pages. Moreover, since such candidate displays over a plurality of pages are displayed in the order of the code of the symbols, it is necessary to search for a symbol to be input from a plurality of pages and touch it with a pen. For this reason, the number of times the screen is scrolled is increased, and as a result, the number of pen touches is increased, resulting in troublesome input for the user.
[0006]
Furthermore, for example, if you enter the full-width “\” symbol by mistake and enter the half-width “\” symbol, you must search for the full-width “¥” symbol from multiple pages to correct it, There has been a problem that it takes much time to select a target symbol from the candidate display during input.
[0007]
An object of the present invention is to solve the above-mentioned problems by arranging symbols in the order of use frequency and arranging the same symbols at the same positions on different pages when half-width symbols and full-width symbols are displayed on a plurality of pages. In addition, another symbol similar to the symbol displayed on the predetermined page appears at the same position on a different page so that the user can select the symbol without changing the position of interest. An object of the present invention is to provide a data input device that can eliminate the troublesome input caused by an increase in the number of pen touches and reduce the time for symbol selection.

[0038]
In the symbol table 70 stored in the storage device 7, character sets of symbols displayed as candidates in the candidate display area 120 of the symbol board 100 are classified and stored for each page. Specifically, the symbol data of a plurality of half-width symbols displayed on the half-width page and the arrangement data thereof are stored in the half-width page storage area 71, and the full-width symbol having many symbol types is represented by the full-width symbol data displayed on the full-width page and its arrangement. Data is stored in the full-width page storage areas 72 to 79 over a plurality of pages.
[0039]
The number of storage areas, that is, the number of pages is not limited as shown in the figure, and can be changed according to the number of symbols to be displayed as candidates.
[0040]
As shown in FIG. 3A, a plurality of half-width symbols displayed on the symbol board 100 are stored in the half-width page storage area 71 so that the symbols are arranged in order of use frequency, and the full-width 1 Full-width symbol data and layout data stored in the page storage area 72 are also stored so that the same symbol type as the half-width symbol is displayed in the same layout.
[0041]
Therefore, for example, when “¥” is entered as a full-width character, and a half-width character is entered by mistake, the full-width page can be displayed by touching the full-width icon 101 of the symbol board 100 with a pen. Since "\" is displayed at the position, there is no need to find where the target symbol is on the page, and operations such as scrolling multiple screens many times can be reduced, so correction can be performed with fewer pen touches. It can be carried out.
[0042]
Further, the full-width symbol data stored in each storage area from the full-width 2-page storage area 73 to the full-width 8-page storage area 79 and its arrangement data are displayed on the half-width page in addition to the above-mentioned order of use frequency. The full-width symbols that are the same as part of the half-width symbols are stored so that they are always displayed at the same positions as the positions where the half-width symbols are arranged on all pages of the full-width page.
[0043]
FIG. 5A shows an example of symbols and their arrangements displayed as candidates on a half-width page, and FIGS. 5B and 5C show examples of symbols displayed on the second and subsequent full-width pages and their arrangements. .
[0044]
In FIG. 5B, a full-width symbol identical to the symbol “¥ @% $” which is a part of the half-width symbol displayed on the half-width page shown in FIG. 5A is displayed at the same position on one full-width page. Different full-width symbols are displayed in other portions. Further, as in the example shown in FIG. 5C, the full-width symbols corresponding to the symbols displayed on the half-width page are displayed at the same position for the portions other than “-_ \ ￣” on the full-width two pages.
[0045]
Therefore, frequently used symbols such as currency symbols are displayed over a plurality of full-width pages in the same arrangement as the half-width pages, so that the number of times the screen is scrolled can be reduced and the time required for input work can be shortened. it can.
[0046]
Further, when there are a plurality of similar symbols as shown in FIG. 6, the symbol data and the arrangement data are stored in each storage area so that the similar symbols are always arranged at the same position or the same range after the second page of full-width. FIG. 6A shows a display of one full-width page. First, a full-width symbol similar to a part of this full-width symbol is displayed as shown in FIG. 6B and FIG. For example, similar symbols such as parentheses are arranged in the same range. That is, a similar symbol is arranged at the same position on each page, such as “..” on the full-width page 2 and “...
[0047]
Therefore, even when inputting a similar symbol, if you want to input “...”, you can search for “...” by simply scrolling focusing on the position of “•”. The number of pen touches for searching from the inside can be reduced, and the time required for searching for symbols can be reduced.
[0048]
The symbol data stored in the symbol table 70 of the storage device 7 and its arrangement shown in the above example are merely examples, and examples of symbols that are always displayed on each page and examples of similar symbols can be changed. Is possible.
[0049]
