Abstract

(57) [Abstract] [Purpose] It is possible to easily change the assignment of the key function of the data processing device, which is key-customized by one user, to improve the usability of other users. [Structure] In a key input step 501, a key input from the BIOS is fetched as a key code and the shift state of the keyboard is investigated. If there is no key input (step 502), the key input process is terminated. When there is a key input (step 502), a key code conversion step 503 converts the key code into a function code for each function for operating. If the converted function code is a code that does not activate the key assignment changing process (step 504), other processes (screen display process, print process, etc.) are performed (step 505). Also,
If the function code resulting from the conversion is a code that activates the key assignment changing process, the table changing process (step 5
06).

SUMMARY OF THE INVENTION The above-mentioned prior art is
It is premised that there is one operator for each data processing device, and no consideration is given to the use of a data processing device key-customized for one operator by another operator. As OA is advanced as in recent years, one small data processing device is usually used by one person. However, a terminal device or the like connected to a large host computer is usually shared by a large number of people. If another operator operates such a terminal device without knowing that the key has been customized for a certain operator, a command different from the intended command may be keyed in, which is a problem.

An object of the present invention is to provide a data processing device in which key function allocation can be easily changed.

[0006]

The above object is to provide a key input acquisition means for acquiring a key input signal as a key code from hardware or a BIOS, and a process inside the data processing device by the key code acquired by the key input acquisition means. Key code conversion means for retrieving a code representing a type of processing corresponding to a key code conversion table, which is a code table representing the type of the key, and a code obtained by the key code conversion means for changing the key allocation. A key assignment change key determination means for determining whether or not a key is present,
This is achieved by providing table changing means for changing the key code conversion table to change the key assignment when it is determined by the key assignment changing key determining means that the key input is for changing the key assignment. It

[0007]

When the operator uses the terminal device (data processing device), he / she makes a key input to change the key assignment and then customizes his / her own key. The conversion table is rewritten by the table changing means. This allows
The operator will be able to enter keys according to his or her own key customization.

And a bus 115 interconnecting these.

FIG. 2 is a functional block diagram of the data processing apparatus shown in FIG. This data processing device has a communication line 213.
The keyboard 211, the CRT 210, the terminal control unit 201, the key conversion processing unit 202, and the key conversion table file 214 constitute a main part thereof. The terminal control unit 201 further includes a display control unit 203, a key input processing unit 204, a print control unit 205, and a line control unit 2.
And 06. Also, the key conversion processing unit 20
Reference numeral 2 further includes a key conversion unit 207, a key conversion table changing unit 208, and a key conversion table file changing unit 209.

FIG. 3 is a memory map configuration diagram of the internal storage device. This memory map has an operating system (OS) area 301 and terminal software 305. Data is read from the key conversion table file 214 and placed in the area 304 in the key conversion table 304 when the terminal is activated.

FIG. 4 is a flowchart showing a processing procedure performed by the terminal control unit 201 shown in FIG. The terminal control unit 201 performs initial setting so that the terminal software can operate when the terminal software starts operating (initialization step 401), and performs data reception processing from the communication line and data transmission processing to the communication line. Do (Line control step 40
2) Determine the type of the input key and perform the process corresponding to that key (key input processing step 403), and determine whether to terminate the terminal software when it is determined to be the end key in the key input step 403. (End determination step 404). In this key input process step 403, a key assignment changing process is performed.

FIG. 5 is a flow chart showing the detailed procedure of the key input processing step 403. In the key input step 501, the key input from the BIOS is fetched as a key code. This key code, as shown in Figure 8,
It is composed of a scan code and a character code. The scan code shows which key on the keyboard is pressed, and the character code shows the code of the character that should be displayed by pressing that key. .. Key input step 5
In 01, the shift state of the keyboard is also checked.
The shift state of this keyboard is 1 as shown in FIG.
Capture as byte data. Corresponding bit is "1"
Is meaningful when. If there is no key input (step 502), the key input processing step 403 ends. Further, when there is a key input (step 502), a code for each function for operating the key code in the key code conversion step 503 (hereinafter referred to as a function code).
Convert to. If the function code resulting from the conversion is a code that does not activate the key assignment changing process (step 50)
4) and other processing (screen display processing, printing processing, etc.) is performed (step 505). If the converted function code is a code that activates the key assignment changing process, the table changing process (step 506) is performed.

FIG. 13 shows an example of keyboard layout. The operation procedure of the key input process when the Enter key 1304 of the character key unit 1301 is pressed is as follows. When the key code of the Enter key is fetched in the key input step 501, a code "1C0D" in hexadecimal (hereinafter, hexadecimal is represented by adding H to a numerical value) is fetched. "1CH" is the scan code and "0D
"H" is a character code. When the shift state of the keyboard is read, it is "00H". That is, the shift keys are not pressed at all.

FIG. 7 is a block diagram of a key code conversion table showing a function code for searching a function code using the scan code, the character code, and the shift state of the keyboard. The function code is 2-byte data. Base case when the shift state is not shifted for one scan code, shift case when the shift key is pressed, Ctrl
6 of the Ctrl case when the key is pressed, the Alt case when the Alt key is pressed, the kana case where the kana key is input, and the kana shift case when the shift key is pressed while the kana key is input.
The streets correspond to the normal order. Further, the six sets are arranged in the normal order from the scan code “00H” to the “FFH”. When it is determined that there is a key input (step 502). Key code conversion is performed (step 503). The calculation of the address corresponding to the key code in the key code change table is performed by [scan code * 6 + shift state number]. Here, the shift state numbers are "1" for Base case, "2" for shift case, "3" for Ctrl case, "4" for Alt case, "5" for Kana case,
The Kana shift case is "6".

When the input key code is "1C0DH" and the shift state is the Base case, the corresponding place in this table is 1CH * 6 + 1 = 169 (th). The number 169 is "0800H" (a code meaning that a transmission operation is requested). Since this is not a key assignment change start (step 504),
This function code "0800H" is the key processing (step 5
05) and the transmission operation is performed.

Now, let us assume that the key for changing the key assignment is "Ctrl" + "M". "Ctrl"
The operation when the + M key is pressed will be described. When the key code is fetched in the key input step 501, “320
DH "is captured. "32H" is a scan code and "0DH" is a character code. When the shift state of the keyboard is read, it is "02H", which means that the Ctrl key has been pressed. In the key input presence / absence determining step 502, since it is determined that there is a key input, the key code converting step 503 is executed. Similar to the Enter key, the corresponding address in the key code conversion table is calculated as 32H * 6 + 3 = 303 (th). The 303rd key code conversion table is searched, and the function code "2B0" for activating the key table conversion process is searched.
1H ”is obtained. Next, in the determination step 504 of key assignment change activation, since the function code is determined to be the key assignment change activation, the key table change processing step 506.
Is executed.

FIG. 6 shows the key table change processing step 5
It is a flowchart which shows the detailed procedure of 06. This Figure 6
13, the Enter key 13 in the character key section of FIG.
A process of changing the function of 04 to the function of the Enter key 1305 of the ten-key portion will be described. First, changeable keys are displayed (step 601). FIG. 9 is a diagram showing a screen display example at this time. Next, the user selects the Enter key of the character key portion which is the key to be changed (step 602). Next, E on the numeric keypad that is the key to be assigned
The enter key is selected (step 603). If there are other changes (step 604), step 6
Returning to 01, the change process is continued. In this case, Ent
Since only the er key is changed, it is determined whether to write the file next (step 605). If writing to a file (step 605), the function codes of the Enter key of the character key section and the Enter key of the ten-key section of the key code conversion table file are exchanged (step 606). If the key code conversion table 304 read in the memory is changed (step 607),
Entity of the character key part of the key code conversion table 304
The function codes of the r key and the Enter key of the numeric keypad are exchanged (step 608). Finally, the screen display before the execution of the key table change processing 506 is restored (step 6).
09).

Here, if only the key code conversion table read in the memory is changed without changing the key code conversion table file, when the terminal software is restarted, the key assignment is the same as before the change. Will remain. By providing such a function, when another user uses this terminal device and changes the key assignment, it is possible to prevent the original user from having difficulty in using the key assignment because of the change. Further, even if the key code conversion table file is changed by another person, it is possible to easily confirm or investigate the key currently assigned in step 601.

Next, the case where the key assignment "Ctrl" + "M" for changing the key assignment is changed to the "Esc" key will be described. In the above method, "Ctr
If you change the function of "l" + "M" to the "Esc" key,
The person who changed the key now knows that the "Esc" key is a key for changing the key assignment. However, when the person who changed the key forgets the function assigned to the "Esc" key, or when another user uses this terminal, he / she does not know what the key is to change the key assignment. Therefore, as shown in FIG. 12, the current key assignment change key is displayed on the screen.

The key input processing is realized as shown in FIG. Here, steps 1102 and 110
3, 1104, 1105, 1106, and 1107 are shown in FIG.
Steps 501, 502, 503, 504, 505 of
This is the same processing corresponding to 506. In the key input process,
First, the key assignment change key is displayed on the bottom line of the screen (step 1101). When the key assignment change key is changed in the key code conversion table changing process (step 1108), the key assignment change key is displayed at the bottom line of the screen (step 1109). When the key assignment conversion key is not changed in the key code conversion table changing process (step 1108), the process returns.

[0021]

According to the present invention, the key layout can be assigned to the most convenient key layout for each user, and the key layout can be easily changed in advance so that the usability of the data processing device is improved. Since a key code conversion table is provided and the key assignment is changed by rewriting this table, there is an effect that the key assignment can be changed without interrupting the connection with another computer such as the host computer.
