2. Description of the Related Art For example, a portable terminal device of a certain type has a function of storing a large number of names and classifying and displaying the stored names according to a user's instruction. FIG. 7 is an explanatory diagram showing an example of a liquid crystal display screen when data is input to such a mobile terminal device. In this example, the name column 10
“Taro Yamada” is entered in 2, and “work” is entered in the classification item column 104. Further, this portable terminal device can classify names by three items, "employee" is input in the classification item column 106, and "PTC" is entered in the classification item column 108.
Is entered. Input of these data is performed by operating a keyboard, a tablet, etc. attached to the mobile terminal device.

When data is thus input, the portable terminal device stores the name "Taro Yamada" in association with the classification items "business", "employees", and "PTC", and by performing a predetermined operation, the name is stored. When the list display is instructed and, for example, “business” is designated as the classification item at that time, the mobile terminal device displays all the items including “Taro Yamada” classified in the classification item “business” on its liquid crystal display screen. Display name. FIG. 8 is an explanatory diagram showing an example of this classification display. In the figure, what is displayed in the display field 110 on the right side is the telephone number of each person.

Further, when "employee" is designated as the classification item in the list display, the portable terminal device displays all the names classified in the classification item "employee" on its liquid crystal display screen. FIG. 9 is an explanatory diagram showing an example of this classification display. Of course, "Taro Yamada" is also included in this case. Further, when "PTC" is specified, all names including "Taro Yamada" are also displayed in a list.

Further, the classification items to be inputted are arbitrary, and in addition to the above items, various items such as “business partner”, “P project”, “private” can be set. Some relatively low-function devices can set only one classification item for one person.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a functional block diagram showing a main part of a mobile terminal device which is an example of a character data classification device according to the present invention, FIG. 2 is the same configuration diagram, and FIG. 3 is a flowchart showing the operation of the mobile terminal device of FIG. Hereinafter, an embodiment of the portable terminal device and the character data classification method of the present invention will be described with reference to these drawings.

As shown in FIG. 2, the portable terminal device 2 includes a CPU 4, a ROM 6 (read only memory), and an R.
AM8 (random access memory), liquid crystal display device 1
0, a keyboard 12, an interface 14, etc., and operates with a battery 16 as a power source. The ROM 6 stores program data for realizing various functions of the mobile terminal device 2, and the CPU 4 operates based on this program. The RAM 8 stores data such as name, address, telephone number, and classification item. The interface 14 connects the mobile terminal device 2 to a telephone line and exchanges data with a personal computer or the like.

Functionally, as shown in FIG. 1, the mobile terminal device 2 includes a data input means 18, a data extraction means 20, a data registration means 22, and a data output means 24 as functional blocks particularly relating to the present invention. I'm out. Through the keyboard 12, the data input unit 18 includes a character code string forming each of a plurality of classification item data and a character code of “,” (hereinafter, also referred to as a specific character code) interposed between adjacent classification item data. ) Input character code string consisting of and.

The data extracting means 20 identifies the leading and trailing character codes of the classification item data by the specific character code and extracts each of the classification item data from the input character code string. The data registration means 22 stores the classified data such as name, which is composed of one or more character code strings,
It is associated with the classification item data extracted by the data extracting means 20. When the classification item data is designated, the data output means 24 outputs the classified data corresponding to the designated classification item data.

Next, the operation of the portable terminal device 2 thus constructed will be described with reference to FIGS. 3 to 6. When a predetermined operation for inputting data is performed with the keyboard 12, the CPU 4 operates based on the program stored in the ROM 6 and fetches data (step S1). Here, the CPU 4 first displays a screen for data input on the liquid crystal display device 10. FIG. 4 is an explanatory diagram showing an example of such a data input screen. However, although this figure shows a state in which all the data has been input, each data is actually input in sequence as described below, and the input data is displayed on the screen each time.

On this data input screen, there are a name column 26, a phonetic column 28, a classification item column 30, a postal code column 32, an address column 34, a company name column 36, a telephone number column 38, a facsimile number column 40, and a memo column 42. It is included, and the user operates the keyboard 12 to input data in these fields 28, respectively.

In this example, "Taro Yamada" is entered in the name field 26.
Has been input, and “Yamada Taro” has been input in the phonetic field 28. When these characters are input by operating the keyboard 12, the keyboard 12 sequentially generates a character code representing each character, and the CPU 4 receives the character code string and stores it in a predetermined storage area in the RAM 8.

On the other hand, in this example, "work, employee, PTC" is entered in the classification item column 30. That is,
Although work, employee, and PTC are input as classification items, unlike the conventional case, in the mobile terminal device 2 of the present embodiment, these classification items are indicated by “,” in the one-line classification item column 30.
Separated by. CPU4 is the keyboard 1
When such data is input by the operation of No. 2, it operates as the data input means 18 and the character code string forming each of the three classification items, that is, the data of work, employee, and PTC, and between them. The input character code string consisting of the character code of "," intervening in is taken in, and the whole is once stored in a predetermined recording area of the RAM 8.

Postal code column 32, address column 34, company name column 3
Character data corresponding to each of the telephone number column 38, the facsimile number column 40, and the memo column 42 is also input as shown in FIG. 4, but the CPU 4 also applies the same data to the above-mentioned case. Further, it is fetched each time it is input by operating the keyboard 12, and stored in a predetermined recording area of the RAM 8.

After that, the CPU 4 causes the RAM 8 to execute "business,
The above-mentioned input character code string of "employee, PTC" is taken out, and it operates as the data extraction means 20 to separate each classification item data (step S2). FIG. 5 is a flowchart showing the details of this processing. Hereinafter, description will be given with reference to this figure. In this processing, three counters i, j, and n are used, and at step S101, they are first set to 0 and reset. Next, in step S102, a two-dimensional array keys [] for storing the extracted classification item data.
Initialize []. In the figure, MAX_KEYS represents the number of classification item data that can be registered. Therefore, MAX_
The KEYS number of arrays will be initialized. afterwards,
In step S103, the input character code string of "work, employee, PTC" retrieved from the RAM 8 is stored in the one-dimensional array key []. FIG. 6A is an explanatory diagram schematically showing the contents of the array key [] in which the input character code string is stored. The 0 at the end represents a character code indicating the end of the character code string. These sequences key
Both s [] [] and key [] are secured in the RAM 8.

Then, the variable c has the first character code key.
Substitute [0] and increment the counter i by 1 (step S10
4) It is determined whether or not the variable c is 0, that is, whether or not the scan is performed to the end (step S105). in this case,
Since the determination result is No, it is determined in step S106 whether the variable c is a delimiter (META_CHR), that is, ",". Since the result of this determination is also No at this stage, the routine proceeds to step S107, where the variable c is stored in the array keys [] [] as the jth character code of the nth classification item data, and the counter j is incremented by 1. In this case, n and j are both 0, so the variable c is stored in keys [0] [0].

After that, returning to step S104, the character code key [1] is substituted for the variable c, and the counter i is further advanced by one. After that, the above procedure is repeated. Then, when “,” is substituted for the variable c from key [], the determination result is Yes in step S106.
Therefore, the process proceeds to step S108 and the array key is
0 is stored in s [] [] as a terminal symbol. As described above, the first classification item data “business” has been extracted, and each character code is stored in the first row of the array keys [] [] as shown in FIG. 6B. .

Next, in step S109, the classification item data to be newly extracted is written in the second row of the array keys [] [], so the counter n is advanced by 1 and the counter j is cleared to 0. Then, in step S110, it is determined whether or not the number of class item data (MAX_KEYS) that can be registered has been reached. In this case, since the determination result is No, the process returns to step S104 and the above processing is repeated.

As a result, similarly to the case of "business", "employee" is extracted as the classification item data, and the array k
The character code string is stored in the second line of eys [] [] as shown in FIG. In addition, "PT
Similarly, "C" is extracted, and the array keys [] [] is extracted.
The character code string is stored in the third line of.

If the number (MAX_KEYS) of the classification item data that can be registered in this portable terminal device 2 is 5, for example, even if the third "PTC" is extracted, the determination result in step S110 is Yes. Not
Therefore, the process returns to step S104 again. Then, 0 is assigned to the variable c, and as a result, the determination result in step S105 becomes Yes. Therefore,
The process proceeds to step S111, and the array keys [] []
0 is stored as the terminal symbol at the end of the third line of.

When five or more classification item data are input, the determination result becomes Yes in step S110 at the stage of extracting the fifth classification item data, and the process is ended at the end of this step. become.

Next, the CPU 4 operates as the data registration means 22 and stores the three classification item data extracted as described above in the RAM 8 in association with the data of the classified data "Taro Yamada" ( In step S3), other data such as other addresses and telephone numbers input at the same time are also stored in the RAM 8 in association with each other.

When the registration of such data is completed, thereafter, a predetermined operation is performed with the keyboard 12, and, for example, when a list display of a name and a telephone number is instructed, the CPU 4 operates as the data output means 24, At the same time, a list of names and telephone numbers is displayed based on the classification items designated by operating the keyboard 12 (step S4).

Here, for example, when "business" is specified as the classification item, the CPU 4 retrieves from the RAM 8 the data of the name and telephone number stored in the RAM 8 in association with the "business" as the classification item data. It is displayed on the screen of the liquid crystal display device 10. The display result is as shown in FIG. 8 as in the conventional case.

Further, when "employee" is designated as the classification item, the CPU 4 determines "employee" as the classification item data.
The data of all names and telephone numbers stored in the RAM 8 in association with are retrieved from the RAM 8 and displayed on the screen of the liquid crystal display device 10. The display result is as shown in FIG. 9 as in the conventional case. further,
When "PTC" is designated, all the names stored in this classification item are similarly displayed in a list together with the telephone numbers.

Then, in the portable terminal device 2, as described above, a plurality of classification items are indicated by "," in the classification item column 30 of one line.
Since the input is divided by, the display space is 1/3 as compared with the conventional case where three classification item data are input in three lines. Therefore, as shown in FIG. 4, two lines can be secured as the address column 34, and two lines can be used as the memo column 42.

Further, when the user is a beginner and the number of classification items to be used is sufficient, the user may simply enter only one classification item data in the classification item column 30. The reason why a plurality of classification item columns are provided as in the past cannot be understood immediately, and there is no confusion about the operation.

In this embodiment, the number of class item data (MAX_KEYS) that can be registered is 5. However, this number is of course an example, and it is arbitrary according to the specifications required of the device. You can set it to. Further, although the keyboard 12 is used as the input means in the above embodiment, it is of course possible to configure the input means using a tablet, a mouse or the like. Further, although the specific character code to be interposed between the plurality of input classification item data is the character code of “,” in the above embodiment, other than the comma, slash, semicolon, hyphen, etc. are used as delimiters. , It is also effective to use those character codes.

[0036]

As described above, in the character data classification method of the present invention, first, in the data input step, a plurality of classification item data and a specific character code interposed between adjacent classification item data are used. The input character code string is fetched through a predetermined data input means. Then, in the data extraction step, the beginning and end character codes of the classification item data are specified by the specific character code, each of the classification item data is extracted from the input character code string, and in the data registration step, the classified data Is associated with the classification item data extracted in the data extraction step.

Further, in the character data classification device of the present invention,
First, the data input means takes in an input character code string consisting of a plurality of classification item data and a specific character code interposed between adjacent classification item data, through a predetermined data input means. Then, the data extracting means identifies the leading and trailing character codes of the classification item data by the specific character code, extracts each of the classification item data from the input character code string, and the data registration means extracts the classified data. The data is associated with the classification item data extracted by the data extracting means.

Therefore, in the present invention, since a plurality of classification item data are continuously input with a specific character code interposed, the input character code string input is displayed on one line of the display screen. Therefore, the required display space can be significantly reduced compared to the conventional case. Therefore, in the case of a mobile terminal device or the like, it is possible to secure a sufficient space in the address field or the memo field.

Further, when the user is a beginner and one classification item to be used is sufficient, the user only needs to input one classification item data. It is not possible to immediately understand the reason why a plurality of classification item columns are provided as in the case such as the above, and there is no confusion about the operation.
