It is composed of a CPU and the like. The arithmetic unit 4 appropriately reads out programs and data from the storage device 3 based on control information and coordinate position information according to the operation state of the mouse from the coordinate input device 2 and performs each process.

Display of data will be described with reference to FIG. 2 for easy understanding of the present invention. FIG. 2A shows a conventional display method, and FIG. 2B shows a display method according to the present invention. The present invention rearranges data such as specific names (names, company names, etc.), telephone numbers, e-mail addresses, etc. in the order of specific keywords such as names, numbers, etc., and arranges specific keywords in alphabetical or alphabetical order. Applicable when displaying data using tags.

As an example, the predetermined display characters of each tag are five characters “A, I, U, E, O”, and the screen of the display device 1 has seven characters due to the limitation of the display area and the like. It is assumed that data can be displayed at the same time only up to the number. And
It is assumed that there are six pieces of data of "A" and ten pieces of data of "I", "U", "E", and "O", each of which is rearranged in the order of Ai-O-O.

When the interval between display characters of each tag is fixed in advance as in the prior art, data is displayed as shown in FIG. 2A. In FIG. 2A, 51 is a tag of “A”, and 52, 53, 54, and 55 are tags of “I”, “U”, “E”, and “O”. FIG. 2A
Indicates that the tag “A” is selected by the coordinate input device 5 such as a mouse and the result is displayed, that is, six tag data with “A” as an initial is displayed. "Ah"
When other tags are selected, one tag data is displayed. Thus, due to the bias of data,
The amount of tag data differs for each tag, and the number of operations of the coordinate input device 5 required to search for target data (such as a telephone number) differs depending on the tag.

According to the present invention, the tag interval is changed so that the tag data becomes substantially equal. In the case similar to FIG. 2A, the tag “A” is divided into three so as to include two data each, and the tags “I” to “O” are divided into two tags each including two data. Put together. In this way, the new five tags have equal two tag data. As a result, data is displayed as shown in FIG. 2B.

That is, in FIG. 2B, reference numerals 61 to 65 represent five new tags formed by changing the intervals. That is, a tag 61 of “Ah-Au”, a tag 62 of “Ah-Ao”, a tag 63 of “Aka-An”,
A tag 64 of "I-U" and a tag 65 of "E-O" are set. As a result, the tag data belonging to each of the tags 61 to 65 is equal to two. FIG. 2B shows a state where the tag 61 is opened and two pieces of tag data are displayed.
To open another tag, the part of the heading character is clicked with the mouse. By making the tag data of each tag substantially equal, the number of operations of the input device for searching for the target data can be made substantially equal.

In the example of FIG. 2B, the total number of data to be searched is 1
A description will be given of a case where there are 0 data but a case where there are 100 data to be searched. For example, 60 tags
It is assumed that there are 20 data for each of "i", "u", "e", and "o". In the conventional method, considering that the number of data that can be displayed simultaneously is seven, when displaying the 60th final data of the tag “a”, after selecting the tag of “a”, pressing the scroll button seven times There is a need.

In the present invention, the intervals between the tags are changed so that five new tags are created so that all five tags have the same 20 data. FIG. 3 shows a display when there are 100 data. As in FIG. 2B, the tag of “A” is divided into three tags 61 of “Ah-Au”, a tag 62 of “Ah-Ao”, and a tag 63 of “Aka-An”. Also,
"I-U" tag 64, which summarizes "I" and "U" tags, "E-O", which summarizes "E" and "O" tags
Is set. As a result, each tag 61-65
, And the tag data belonging to each becomes equal to 20 pieces.

FIG. 3 shows a state in which the tag 63 is selected and the third page of the tag 63 is opened by operating the scroll buttons 71 and 72 for scrolling the display forward and backward, respectively. Because it is the third page, six tag data "Aki No. 15""Aki No. 16"
“Aki No. 17”, “Aki No. 18”, “Aki No. 19”, and “Aki No. 20” are displayed.

In the present invention, since each of the tags 61 to 65 has the same 20 tag data, even when the final data of each tag, for example, “Aki No. 20” is displayed, the scroll button 72 is displayed. By clicking twice with the mouse, the target data can be displayed.

The processing of the above-described embodiment of the present invention will be described below. FIG. 4 shows a data display method and a processing procedure of search processing. As shown in FIG. 4, first, a tag is selected by a mouse (step S1). In step S2, the operation state of the mouse in step S1 is detected. When the mouse is single-clicked, it is determined that the tag is selected, and when this is double-clicked,
It is determined that the display mode of the tag has been changed.

If it is determined in step S2 that the input is a tag selection input, the process proceeds to step S4, in which tag data specified by the selected tag is extracted (step S4), and the display of the display device 1 is performed. Tag data is displayed on the screen (step S5). As a display mode of the tag data, a fixed tag (in the conventional method, for example, FIG.
A) or a variable tag (in the method according to the invention, eg FIG. 2B, FIG. 3).

If it is determined in step S2 that the display mode has been changed, the flow shifts to step S3 to determine the display mode of the currently set tag. If it is determined in step S3 that the current display mode is the variable tag, the display mode is changed to the fixed tag, and the process proceeds to step S11. On the other hand, when it is determined in step S3 that the display is to be performed by the fixed tag, the display is changed to the display by the variable tag, and the process proceeds to step S21.

When the display mode is changed to the fixed tag, the data is read from the storage device 3 in step S11, and the data is sorted (step S1).
2). Then, tag data assigned to each tag is extracted (step S13). Then, the tag and the tag data of the selected tag are displayed on the display screen of the display device 1 (step S14). FIG. 2A is an example of display using a fixed tag.

When the display mode is changed to the variable tag, the data is read from the storage device 3 in step S21, the data is sorted, and the number of data is counted (step S22). In the next step S23,
From the total number of data, tag headings are generated such that the tag data of each tag is equal. The number of tags is fixed for fixed tags and variable tags. However, the number of tags may be different between the two.

Then, tag data corresponding to each created tag is extracted (step S24). Step S2
In 5, the created tag and the tag data of the selected tag are displayed on the display screen of the display device 1. As described above, when the number of data items that can be displayed is limited, tags and tag data are displayed using a plurality of pages. 2B and 3 are display examples of the display mode of the variable tag.

When displaying tag data according to the embodiment of the present invention, a plurality of data such as a name, a telephone number and an address may be displayed. After the tag data is displayed, target data may be selected from the displayed data, and another data accompanying the target data may be displayed.

Further, an application example in which the present invention is applied to a portable information device having a telephone function will be described with reference to FIG.
