Abstract

PURPOSE:To improve user's operability by setting a converted KANA(Japanese syllabary)/KANJI(Chinese character) mixed sentence to be a Japanese input to the inside of a device. CONSTITUTION:At the time of detecting the operation of a Japanese input starting key, CPU22 starts a KANJI conversion program through the use of a user interface program. Then, whenever a KANA character string is inputted from an input part 20, a key identification program detects the input of the KANA characters. Next, after confirming that a Japanese input function (mode) is set, a CPU22 converts the inputted KANA string into a KANJI mixed sentence by a KANJI conversion program. At this time, the KANJI dictionary of a dictionary part 25 is referred to. The KANJI mixed sentence converted like this is displayed on a display part 21 by a resident program in the CPU22. The Japanese input can be executed by permitting the CPU22 to execute a processing like this.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device capable of inputting Japanese.

[0002]

2. Description of the Related Art A conventional portable terminal device called a handy terminal is mainly used for collecting business activity data and inputting meter reading data to a host device, and has almost no Japanese input function. It was Even if the mobile terminal has a Japanese input function, the type of kanji conversion is limited to single kanji conversion or idiom conversion,
Most of the input means were also made from the keyboard.

[0003]

Recently, there have been increasing demands for a Japanese input function which is easy to use because the portable terminal device has various purposes. However, the above conventional example has the following drawbacks. That is, since the kanji conversion method is only single kanji or idiom conversion, the input operation is complicated and there is a problem in operability.

Therefore, in view of the above points, the present invention has an object to provide a portable terminal device in which the operability of a user involved in Kanji conversion is improved.

[0005]

In order to achieve such an object, the present invention corresponds to a kana input means for inputting a kana and a kana in a portable terminal device for inputting data to a host device. The kana-kanji mixed sentence converted by the kana-kanji mixed sentence, which includes a dictionary part in which kanji is written and a kana string in sentence units input from the kana input means, is converted into a kana-kanji mixed sentence by referring to the dictionary part. It is characterized by inputting Japanese into the device.

[0006]

In the present invention, kana-mixed kanji conversion, that is, kanji conversion in sentence units, is performed to improve user operability.

[0007]

EXAMPLES The present invention will be described in detail below based on examples. FIG. 1 is a software configuration diagram relating to the Japanese input function in the portable terminal device according to the present invention. An outline of Japanese input processing will be described with reference to FIG.

The numbers enclosed in parentheses in the figure show the flow of processing corresponding to the following processing numbers.

(1) When the application program 10 stored in a memory card or the like is loaded and activated, the power-on processing 130 in the application interface unit 13 is activated.

(2) The power-on processing 130 initializes the user interface unit 11 and the Kanji conversion unit 12, and the user interface unit 11 executes system processing related to character input and display. The Kanji conversion unit 12 converts an input Kana string into a Kana-Kanji mixed sentence using a dictionary.

(3) In the power-on process 130, the resident program 131 in the application interface unit 13 is made resident by using the resident unit 14.

(4) The resident program 131 identifies the key input of the input unit 20 described later, and, for example, monitors the Japanese input activation key and, when detecting it, makes a far call to the user interface unit 11.

(5) Further, the resident program 131 uses the main body 132 in the application interface section 13 to display the key pattern.

(6) The user interface section 11 converts a key code input from an application program or an input section (for example, a touch panel) into Kanji by using the Kanji conversion section 12, and the result of the conversion is used as a Japanese input in the apparatus. To use.

(7) When the Japanese input is completed, the user interface section 11 stores the data 7 in the resident program 131.
To return.

(8) The resident program 131 returns the received data to the application program.

(9) Further, the application interface unit main body 132 activates the Kanji conversion unit 12 via the user interface unit 11 when detecting the software interrupt of the application program. Therefore, the Japanese input mode is automatically set when the application program is executed.

FIG. 2 is a block diagram showing the hardware configuration of this embodiment.

In the figure, reference numeral 20 denotes an input section having a Japanese input function activation key for instructing activation of the Japanese input function except when the Kana input key and the application program are executed. Reference numeral 21 denotes a display unit, and in this embodiment,
The input unit 20 and the display unit 21 are integrated using a touch panel in which transparent touch keys are stacked on the LCD.

Reference numeral 22 is a central processing unit (CPU) for controlling the Japanese input function, 23 is a buffer memory for storing data, and 24 is a control program storing software for realizing the functions of the respective parts described in FIG. Memory, 2
Reference numeral 5 denotes a dictionary unit (dictionary memory) used when converting kana and kanji. A kanji character string corresponding to the kana character string is described in the dictionary section 25.

Reference numeral 26 is a memory card in which an application program for executing arithmetic processing according to the user's purpose is stored.

FIG. 3 is an explanatory diagram of a kanji conversion operation.
Is an example of conventional phrase conversion, and 31 is an example of batch conversion of sentences in the present embodiment. Although inputting the sentence "travel is companion" requires two conversion operations for idiom conversion, one operation is sufficient for batch conversion of sentences. The sentence batch conversion can be realized by having phrase information in the dictionary and converting a plurality of phrases in one conversion operation. Kana-mixed Kanji conversion is well known, and detailed description thereof will be omitted.

FIG. 4 is an explanatory diagram of making the device resident. When the program to be controlled becomes large, the program usually cannot fit within 1 MB of the address space. Therefore, by providing a resident program management unit in 1MB and arranging the program there, the resident program can always make a corresponding function call.

The circuit operation of FIG. 2 will be described with reference to FIG. FIG. 5 shows a system control processing procedure executed by the CPU 22 of FIG. This processing procedure is stored in the control program memory 24.

When the application program of the memory card 26 is activated in response to the power activation, the CPU 22
Advances the execution procedure to the power-on process in response to the power activation (step 500 → 13 in FIG. 5). This power-on process corresponds to the power-on process 130 of FIG. Next CP
U22 executes a subroutine program for an application interface (corresponding to the application interface section 13 in FIG. 1) to execute initial processing of a user interface program and a kanji conversion program, and at the same time gives execution permission of the kanji conversion program by a flag or the like ( Step 550 of FIG. 5).

Next, the CPU 22 reads the application program from the memory card 26 by the user interface program and starts the calculation (steps 560 → 570 in FIG. 5).

When Japanese input is required on the user program, that is, Kanji conversion of the kana character string is requested during execution of this arithmetic program, the Kanji conversion program is started in the user interface program to perform the Kanji conversion process. (Corresponding to the Kanji conversion unit 12 in FIG. 1) is performed. In this case, there are two cases, that is, Kana conversion of the Kana string written on the application program and Kana conversion of the Kana string input from the input unit 20.

On the other hand, when the user operates the Japanese input start key of the input unit 20 in the system processing mode without executing the application program, the CPU 22
Reads out the key identification program in the resident program from the control program memory (corresponding to the resident means 14 in FIG. 1) 24, and identifies the contents of the operation key by this key identification program (step 520 in FIG. 5). Here, when the operation of the Japanese input activation key is detected (step 530 in FIG. 5), the CPU 22 activates the kanji conversion program using the user interface program (step 535 in FIG. 5).

Hereinafter, every time a kana character string is input from the input unit 20, the input of kana characters is detected by the key identification program. After confirming that the Japanese input function (mode) is set, the CPU 22 converts the input kana string into a kanji mixed sentence by the kanji conversion program (steps 11 and 12 in FIG. 5). At this time, the dictionary unit 25
Needless to say, the Kanji dictionary of is referred to.

The Chinese character mixed sentence thus converted is displayed on the display unit 21 by the resident program in the CPU 22 (step 12 in FIG. 5).

By the CPU J22 executing such processing, the CPU 22 can input Japanese in the mode for executing the application and the mode for executing the system processing.

FIG. 6 is a flowchart relating to the display of key patterns for the programs stored in the control program memory 24 and executed by the CPU 22.

When the Japanese input function is activated (step 50), the application interface unit 13
It is identified whether or not the user key pattern is registered (step 51). When the user key pattern is registered in the memory (not shown), the user key pattern information is acquired (step 52), and when it is not registered, the default key pattern information is acquired (step 53).

Details of the key pattern (key code) information are shown in FIG.

Next, the user interface section 11 acquires the cursor position (step 54). The user interface unit 11 determines whether or not the key pattern and the cursor overlap (step 55), and if the key pattern and the cursor overlap, the key pattern is set to a position where they do not overlap (step 56). If they do not overlap, the key pattern is set to the default position (step 57). Then, the application interface unit displays the key pattern (step 58).

[0036]

As described above, according to the present invention, since the text-to-kanji conversion can be performed even on the portable terminal device, Japanese can always be input from the application program, which enhances the operability of Japanese input. A portable terminal device can be provided.
