[Embodiments of the invention]

An embodiment of the present invention shown in FIG. 0 will be described below. FIG. 2 shows a relatively small computer to which the present invention is applied.
-ff This is a block diagram of an A6[I class computer, which is called a personal computer or a business computer.

FIG. 3 is a diagram showing an example of its appearance. In these figures, 1 is a keyboard, 2 is a main processing device, and 3 is a keyboard.
is a display device. The keyboard 1 has a large number of keys arranged as described below.

By pressing each key, predetermined data is input to the processing device. The processing device 2 includes a microprocessor MPU and a read-only storage device (hereinafter referred to as ROM).
, a readable and writable storage device (hereinafter referred to as RAM). The microprocessor MPU is R
A program stored in OM or RAM is read and a predetermined process instructed by the program is executed. The display device 3 displays these processing results, the keyboard 10
It is for displaying input results, etc., and SC indicates the display screen.

The display device places a cursor C8 on the display screen SC to indicate which position on the display screen SC is the processing target position.
Display. The position of this cursor C8 is in the coordinate storage section XA.
M is determined by the coordinate information stored in YAM. Of these coordinate storage units XAM and YAM, XAM is an X coordinate storage unit that stores coordinate information in the horizontal direction, that is, the X-axis direction, in FIG. This is an X coordinate storage unit that stores coordinate information. By storing predetermined information in these X coordinate storage section XAM and Y coordinate storage section YAM, the display device 1 moves the cursor C8 to a predetermined position based on this content and displays it. These storage units XAM and YAM are R
It is controlled to arbitrary contents by a program stored in the AM or ROM, or by the action of the microprocessor MPU according to the program based on commands from the keyboard 1.

Here, the ROM or RAM includes a selection means MSL,
In order to configure the key code data conversion means KCV, programs shown in flowcharts in FIGS. 4 and 5 are stored. In this flowchart, steps 4α to 4h, which will be described later, constitute a selection means MSL.

Steps 4t to 4τ constitute key code data conversion means KCV. In explaining the embodiment shown in these figures, the outline of the processing will be as follows. That is, in this embodiment, first, the number of keys (horizontal
It is virtually equally divided into n pieces, Yn pieces vertically). This is shown, for example, in FIG. This figure shows the correspondence between the display screen SC of the display device 1 and the keys arranged on the keyboard l. The keyboard 1 is shown as having a general key arrangement. That is, in the example shown in this figure, among the many keys arranged on the keyboard 1, the range represented by H in the horizontal direction and the range represented by V in the vertical direction are used. There are ttx4c] keys in this range. Therefore, for the entire 1 display screen SC, Xn is 11
．． Yn is virtually divided into four. and,
For each key, a position corresponding to the position of the key is allocated one section on the display screen SC. For example, keyboard 1
The upper keys Kx and f, that is, the "l°' (nu) key, are assigned to the virtual section S1 on the display screen SC, and the keys on the keyboard 1 are assigned to the keys 2.
In other words, the 2'' () key is the virtual section S2 of the display screen SC.
Assign to Hereinafter, in the same way, the key 44 on the keyboard 1, that is, the donkey key is the virtual section S on the display screen SC.
Assigned to 44. Furthermore, each virtual partition S1. S2.
One representative point is determined in advance for each of S3°..., S44. FIG. 8 shows an example of this.

FIG. 8 (ta+) shows the case where the upper left end position of each virtual section S is taken as the representative point P, and FIG. 8 (b) shows the case where the central position of each virtual section S is taken as the representative point P. The position of this representative point is not limited to that shown in FIG. 8, but may be any position.

Then, virtual section s1 of one display screen SC. S2. s3
．． ..., 1 to the keys assigned to S44, respectively.
2. 3. ..., any key Kr among the 44,
When the key is pressed, the coordinates of a predetermined representative point PL of the virtual section Si corresponding to this key are set in the aforementioned X coordinate storage section and X coordinate storage section. As a result, the display device 1 displays the representative point p of the virtual section SZ of the display device 1 corresponding to the pressed key KZ.
The cursor C8 is controlled to move to the coordinate position where i is located.

For example, when moving the cursor C8 to a desired coordinate position, first press the key KL corresponding to the virtual section SL that includes that position, and move the cursor C8 to the representative point PL of the virtual section Sc. This allows coarse adjustment of cursor movement.

1- Therefore, it is extremely easy to move the cursor from one position to another. In Fig. 21.

Virtual sections S, , S2 . of the display screen SC. S3. ..., S
44 may display a dashed line or the like indicating this division on the display screen SC as shown in FIG. 1 to make it clear.

It may not be displayed if it is not particularly necessary.

Furthermore, each virtual partition S1. S2. S3. ..., to each key in S44, 2. 3. ..., to make the correspondence with 44 clearer, the symbols 7 assigned to each key, such as "1" (nu), [-2Ji71, 1'-3J (7),
The symbol may be displayed as . 3. In addition, for broken line rings, symbols, etc., move the cursor C8
If it is displayed in a lighter tone, the difference becomes clearer, which is more desirable.

The main parts of this embodiment are as follows. That is, in order to further facilitate coordinate input, as shown in FIG. 1, press any key, for example, the key 5. to move the cursor C8 to the representative point P15 of the virtual section S15. That is, rRJ(
Goods)) When you press the key.

4 on the key located above it. 2 on the key located below
6. 4. to the key located to the left. 16 on the key located to the right, respectively, and move the cursor C8 in the direction shown by the arrow in the figure.
This figure shows a case where is set as a direction control key that moves by a unit amount. i.e. by pressing the key 15 on the keyboard 1.

Section 8 on the display screen SC shown in FIG. 1 in correspondence with FIG. 7
15 representative points P1.5 are displayed. As a result, 15 becomes the center of the key, and until the end key, for example, "Return J key, is pressed, 2 This key KI5 is defined as the center key. 7 Then, the keys around 15 are set to the center key. 4
+K14+Kts, 26, the direction of movement shown in FIG. 1 is defined. That is, when the key 4 is pressed, the point P15 on one screen SC moves in the direction of the arrow YND. Also, if 14 is pressed on the key, point P on the screen
15 moves in the direction of arrow XND. Furthermore, key K16
, if you press 26.

Point P15 moves in the directions of arrows XPD and YPD, respectively. In this case, the character 15 may be displayed on the lower left of one screen SC to indicate which center key has been input, as shown in FIG. The function of the direction control key as described above is, for example, the "return" as mentioned above.
The process ends when the key CR is pressed. Also, when this key CR is pressed, the position of this point is stored internally and the key is placed in the state of waiting for input from the primary keyboard. FIG. 10 shows a key located at the bottom of the keyboard 10.

This example shows the case where the key located at the top row is specified as "1 center key". In this case.

Key 1 located on the top row, for example, key 5. In other words, “5
” key as the center key, 5 itself becomes the northward movement key, and 14 is the leftward movement key 9.
The key K6 is defined as a rightward movement key, and the key K]6 is defined as a downward movement key.

In addition, if the key located at the bottom row, for example, the key 39°, that is, the rNJ key, is used as the center key, 39 itself becomes the downward movement key, 38 is the leftward movement key, and 40 is the key below. is defined as a rightward movement key, and key 28 is defined as an upward movement key. The same idea applies when the center key is set to the rightmost row or the leftmost row.

The figure shows a case where the key 231K33 is selected as the center key. Further, FIG. 11 shows an example (17) in which the four corners of a group of keys with a specified range are set as the center keys. That is, this is the key Kl, to 11
, shows the case where 341K44 is set as the center key.

FIG. 6 is a memory configuration diagram showing an example of a key code storage section configured based on the above. In this embodiment, this key code storage section is configured on RAM Km. That is,
The same number of key code storage units BK1. as the number of keys selected in FIG. 7 are stored on the RAM. BK2.・・・・・・、BK

correspond to 44. That is, the storage section BK1 corresponds to the key 1, and the storage section BK2 corresponds to the key 2.

Hereinafter, the storage unit B K44 similarly associates the key with 44. Each storage unit BK,, BK2. ......, BK44
each have seven memory locations M11M2 +Ma 9M4 ,
Equipped with M51M61M7. The storage location M1 stores the key code of the key corresponding to the key code storage section, and the storage location M22M3 stores the key code corresponding to the key code storage section and the representative point P in the corresponding virtual section on the display screen SC. The coordinate information of
The coordinates are stored in the storage section M3, and the X coordinate is stored in the storage section M3. Memory location M4 v M5* Me * M7 stores information for setting the keys arranged around the key corresponding to the key code storage section as direction control keys for cursor C8; The key code of the key which becomes the control key is stored, the key code of the key which becomes the right direction control key is stored in the storage position M5, and the key code of the key which becomes the down direction control key is stored in the storage position M6.

The key code of the key serving as the left direction control key is stored in the storage location M7. For example, taking FIG. 1 as an example, the explanation will be as follows. key, 5° or rRJ
(, The key code of the rRJ key is stored in the storage position M1 of the key code storage unit BK, 5 corresponding to the -1 key, and the X coordinate of the representative point P15 in the virtual section S15 on the display screen SC is stored in the storage position M22M3. .

Remember the X coordinate. Memory location M4 has a ← code of 4 on the key, and memory location M5 has a key code of 16 on the key.

Memory location M6 has 26 key codes on the key, memory location M
7 stores 14 key codes in the key. Similarly, for each key selected in the range, 2. 44, each corresponding key code storage unit BK1
．． 8 to 2. . . . constitutes BK44. Each keyboard storage section BK1. BK2. ......, BK44
The storage locations Ml, M2, M3, M
4, M5, M6, M7 are each keyboard storage unit BK1. BK2. They are addressed and arranged in this order within the BK44. 5PTR is a pointer storage section similarly arranged on RAM, and keyboard storage section BK1. BK
2. . . . In order to read the information stored at desired addresses of the BK 44, address information specifying each of these addresses is stored.

Note that CHR is a storage unit located at a predetermined address on R, AM, and temporarily stores the key code of one key input from keyboard 1. 4 and 5 will be explained. FIG. 4 and FIG. 5 show a series of processing, and between each figure.

A symbol with a number surrounded by a circle means that it is connected with the same symbol. First, when the routine shown in the flowchart is activated, a pointer 5PTR shown in FIG. 6 is set to the start address of the table CVGM in step 4α. Next, in step 4b, one character of the input key from the keyboard 1 is read, and the key code is stored in the storage section C.
Memorize it in HR. In step 4C, the key code of this read character, that is, the key code and pointer 5PTR stored in the storage unit CHR in step 4h.
Compare the key code stored in the address of Chiful CVGM specified by
．． Transfer fVC processing. If they do not match, step 4C.
in.

It is determined whether the pointer 5PTR specifies the starting address of the final key code storage section BK44, and if so, key input error processing KTNE1 is executed. When the first address of the final block BK44 is touched, the pointer 5PTR is updated by +7 using the step knob 4e, that is, the address of the storage position M1 of the next key code storage section is specified, and the process returns to step 4C. . Below, step 4c.

Steps 4d and 4g are repeated until the input key code matches the key code on the key code storage unit or the pointer 5PTR reaches the final key code in the key code storage unit BK44, that is, storage position M. . Now, if the mutual key codes match at step 40, then X at step 4f.

The X coordinate value is read from the storage units M2 and M3 of the prong, and this value is temporarily stored in the storage units MVX and MVY. This can be easily read by specifying the address one or two addresses ahead of the address specified by pointer 5PTR. Next, in step 4, the storage unit MVX is saved.

The X and Y coordinate values stored in MVY are stored in the X and Y coordinate storage units X AM and Y AM of the two display devices fill, respectively. This causes the 0 display device 1 to step 4.
A cursor is displayed at the representative point of the virtual section corresponding to the key input in step b. For example, referring to FIG. 1, the key pressed in step 4C is key KI5, i.e. rRJ K
) key, a cursor C8 will be displayed at the position of point P15 on the 6-display screen SC. Next step 4h
In.

Storage unit 11M4 * M5 of the corresponding key code storage unit,
Read out the memory contents of M6゜M7, that is, the key codes for each direction control key, and store them in the corresponding memory unit U.
Store in KC, RKC, DKC, LKC. Memory location M
4. M5. M6. The contents of M7 are also current.

Three addresses ahead of the address specified by Voi/Re5PTR.

It can be read by sequentially specifying the addresses 4, 5, and 6 ahead. Next, in step 4L, as in step 4b, input key 1 from keyboard 1 is pressed.
The characters are read and the key code is temporarily stored in the storage section CHR. Next step 4, 4A, 41.4m
, the memory section CH of the key pressed in step 4L
The key code stored in H is stored in UKC from Daple CVGM.

A key code that means an up direction control key, a key code that means a right direction control key, a key code that means a down direction control key, or a key that means a left direction control key transferred to RKC, DKC, LKC. Execute the determination whether it is a code or not. If the key code stored in the storage section CHH is not one of these, key input error processing KINE2 is executed. When the key code read by Step 4i matches the contents of the storage unit UKC.

From step 4, the process moves to step 40. In this step 40, the coordinate value of the inner layer of the Y coordinate storage section YAM of one display device 1 is updated by the unit movement amount of the cursor C8 on the display screen SC. This causes the cursor SC to move upward by a unit amount from the current coordinate position.

The key code read in step 4i is stored in the memory RK.
If it matches the content of C, the process moves from step 4k to step 40. In this step 4p, the contents of the X coordinate storage section XAM of the display device l are displayed using the cursor C
The coordinate values of the cursor C8 are updated as much as the cursor C8 moves on the display screen SC by a unit movement amount of 8. As a result, the cursor SC moves to the right by a unit amount from the current coordinate position.

The key code read in step 4t is stored in the storage unit IT.
) If the content matches the content of KC, the process moves from step 4t to step 4q. In this step 4q, 1
The coordinate value of the contents of the Y coordinate storage unit YAM of the display device 1 is updated by the unit movement amount of the cursor C8 on the display screen SC. This causes the cursor C8 to move downward by a unit amount from the current coordinate position.

The key code read in step 4L is stored in the storage section LK.
If it matches the content of C, the process moves from step 4m to step 4r. In this step 4r, the contents of the X coordinate storage section XAM of the 0 display device 1 are moved to the cursor C
The coordinate values of the cursor C8 are updated as much as the cursor C8 moves on the display screen SC by a unit movement amount of 8. This moves the cursor C8 to the left by a unit amount from the current coordinate position. Steps 4o, 47), 4q
.

When each process of 4r is completed, the process proceeds to step 4.
The process returns to t and the unit movement process of one or more cursors C8 is repeated. Refer to Figure 1 for this.

The specific explanation is as follows. Namely.

In step 4h, storage units UKC and RKC.

DKC and LKC each have 4 + K1 keys.
The key code of 261K14 is stored in 6+ from the key code storage unit BK15. l-So at this point, key 4 is the up control key and key 16 is the right control key.

Key 26 is set as a downward direction control key, and key 14 is set as a left direction control key. As a result, when the key is pressed 4), the cursor C8 displayed on the display screen SC by 40 is moved upward by a unit amount from the current position, and when the key is pressed 16, the cursor C8 displayed on the display screen SC is moved upward by the unit amount. Then, the cursor C8 displayed on the display screen SC by 4ρ is moved to the right by a unit amount from the current position, and when the key 26 is pressed, step 41 is executed, and the cursor C8 displayed on the display screen SC is moved by 4q. Cursor C8 moves downward by a unit amount from the current position, and when key 14 is pressed, step 4/:
, cursor C displayed on the display screen SC by 4q
8 will be moved to the left by a unit amount from the current position. Note that when a movement end key, for example, a "return" key is pressed in step 4t, the process returns to step 4α in step 4n.

As described above, when the cursor C8 existing at a certain position on the display screen SC is moved to another target position, the key Ki corresponding to the virtual section Si including the target position must be pressed. Ba.

The cursor C8 can be instantly moved to the target position or a position close to this position. therefore,
Compared to moving the cursor C8 by a unit amount using a direction control key, the number of key operations can be significantly reduced, and coordinate input becomes extremely easy. Then, by pressing the key KL corresponding to the target virtual section Si, the keys arranged around it are set as direction control keys for moving the cursor C8 by a unit amount, so that the hands on the keyboard 1 are pressed. The travel distance can be reduced and coordinate input operations can be performed efficiently.

In the above embodiment, by pressing any key 1 (i) arranged on the keyboard 1, the cursor C8 is moved to the coordinate position where the representative point PL of the virtual section SL of the display device 1 corresponding to the key KL is located. The case where it also has a control function has been explained.

However, if this function is not required, 1. For example, if you want to set the position of cursor C8 to the current position and assign only the cursor direction control key to any key, 1. For example, delete steps 4f and 4J in Fig. 4. Bye. If I give it a 5 on top of this.

The position of the cursor C8 does not change, and by pressing any key Kt, it is adjacent to the key Kt. Or the key K
The i key and the adjacent key are used as cursor direction control keys, and can be used with.

In other words, when performing an operation, move the keys arranged in the position appropriate to the situation in the cursor direction 1Mj? Can be used as a 1IIJ key.

12, 13, 14, 15, and 16 are flowcharts showing other embodiments of the present invention. In addition to the standard key arrangement section, the keyboard l is generally equipped with a so-called numeric key arrangement section in which numerical keys are arranged in a matrix on the right side of this arrangement section, making it easier for the operator to enter numerical keys. There is. In this embodiment, the numeric keypad can be arranged in any part of the standard key arrangement section according to the operator's request. In this embodiment, the numeric keys may or may not actually be arranged on the keyboard 1. FIG. 18 schematically shows the present embodiment. 45 is the numeric keypad.

Among these keys, a key representative of this numeric keypad 45 is determined. In this embodiment, key "5" is the representative key. Then, by assigning this representative key "5" to any key on the standard key layout section 41, the numeric keypad 45 is set on the standard key layout section 41. Due to this.

Enables numeric input using the set numeric keypad 42.

The setting of the numeric keypad 45 to the Shido key arrangement section 41 is as follows.

Perform the following key operations. That is, l'-ESCJ key 4
Press 4 and then press the key to which the representative key "5" is assigned, in this case the rTJ key 43. rE S Cl key 44
0 indicates that the key pressed next is the key assigned to the numeric keypad 45 to set the position, and by pressing the "T" key 43, the representative key "5" of the numeric keypad 450 is Match the arrangement position of the rTJ key 43. This allows the numeric keypad 450 representative key "5" to be moved to the standard key layout section 41.
This key 43 should match the rTJ key 43 of
The position of is set as the base fishing, and the numeric key arrangement section 42 is set around it. From now on, using this set key, it is possible to input numbers. This setting is canceled by pressing the ESCJ key 44 on the keyboard 1, thereby returning the keyboard 1 to its original function.

In this embodiment, since the position of the numeric keypad 45 in the standard keyboard layout section 41 can only be moved one-dimensionally in the horizontal direction, as shown in FIG. , ie.

The rsJ, rsJ, [J, and rooJ keys are all designated as representative keys to improve operability. In this example, the numeric keypad 45 can be arranged in nine different ways.
There is. In other words, the arrangement of the numeric keys 45, which are 4 vertically and 3 horizontally, is in the arrow sections BKOI K and BKO2K in Figure @19.

. . . Arrangements up to BK09K are possible. This example shows a case where the numeric keypad section 42 is arranged at the section BKOIK position.

BKO2, ......, updated in units of BKO9. C
HR is a storage unit that stores codes corresponding to keys input by the operator from the keyboard 1, and KINM is a flag storage unit necessary for processing.

With reference to the above points, the flowcharts shown in FIGS. 12 to 16 will be described below. Each of these figures shows a series of processes, and a symbol with a number surrounded by a circle means that it is connected to the same symbol in another figure. Here, from step 12α to step 12q, the selection means MST,
I made a camphor.

Steps 12r to t6d constitute key code data conversion means. When the routine shown in the flowchart is activated, in step 12α, one character inputted from the keyboard 1 is read and stored in the storage unit CHR.

In step 12h, the read key code ° is 1'.
- Determine whether it is an ESCJ code.

The rEscJ code is a code that is read when the key 44 in FIG. 19 is pressed. At step L2h, if the read code is not the l'-F, S CJ code, the process moves to step 12C. [If it is an ESCJ code, it is determined in step 12 & whether data is being input using the numeric keys. This is done by determining the flag KINM, which is turned ON during data input using the numeric keys. During input, i.e. flag K
If INM is ON, the memory during numeric key input is canceled in step 12Z, that is, the flag KTNM is set to 0FF.
L: Return to step 12α and wait for variable key input. In step 12g, if the numeric key input is not in progress, that is, if the flag KINM is OFF, step 12
Set memory during numeric key input with f, that is, flag KI
Turn on NM. Then step 12! At I, input one character again from the keyboard l and store kone in the storage section CHH. In step 12A, the stored character code is determined, and if it is an [E'scJ code, the memory during numeric key input is canceled in step 12Z, and the process returns to step 12α. Step 12i If a code other than the Step 12q TerE S Cl code is read, proceed to step 12i.
Transfer processing to Here, the pointer 5PT shown in FIG.
Set R to the first address of the first key code storage section BKOI. In step 12), the code stored in the storage section CHR in step 12F is compared with the key code stored in the address specified by the pointer 5PTR, and if they match, the process moves to step 12q. If they do not match, in step 124, the code is stored in the storage unit CHR.

Compare the key code stored at the address specified by pointer 5PTR with 1 added.

If they match, proceed to step 12q. - If not, then in step 12m, the code stored in the memory section CHRK is compared with the key code stored at the address specified by pointer SP'1 plus 2, and if they match. If so, the process moves to step 12q. If they do not match, then in step 120 the storage unit C
The code stored in HR is compared with the key code stored in the address specified by pointer 5PTR plus 3, and if they match, the process moves to step 12.7. In steps 12j to 12n, the key code read in step 12y is transferred to the pointer 5PT.
It is determined whether or not the code matches the representative key code corresponding to the block to which the address specified by R belongs (7).

Steps L2j, 12A, 12m, 12n
If the key codes do not match in any of the above, the specified position of pointer 5PTH is the final position in step 12.7.

That is, it is determined whether or not the key code storage unit BKO9 has been reached. If the final position has been reached, key-in error processing KINE3 is performed. If the final position has not been reached, the pointer S is moved in step 127).
After increasing the contents of PTH by 12 and updating it to specify the primary key code storage section, return to step 12j and select 1.
Repeat the same process for the next key code storage unit - C0
Step 12)', 12, 12m, 12n
If the key codes match in any of the steps, the process moves to step 12q, and the key code storage unit BKO specified by the pointer 5PTR at that point is stored.
The storage contents of L, BKO2, . . . , BKO9 are directly transferred and stored in the storage unit MATCM. FIG. 17 shows the case where the numeric keypad is set at the position of section BKOIK in FIG. 19, that is, r2J, rWJ, rsJ.
, rXJ key is pressed as a representative key. In other words, in the storage section MATCM.

All the key codes stored in the key code storage unit BKOI have been transferred by the process of step 12q.

Thereafter, in step 12α, one character is inputted again from the key fob 1, and this is stored in the storage unit CHR.

If the input key code is not the l'-E S Cl code, it is determined in step 12A and the process proceeds to step 12C.
Transfer processing to Here, it is determined whether or not numeric key input is in progress, that is, the numeric key input memory flag KINM is O.
Determine whether it is N or not. If numeric key input is not in progress, in step 12d, the key code read in step 12α is set on the display section as is, and the process ends. If numeric key input is in progress, step 12r
The process moves to and the ° code stored in the storage unit CHR in step 12α is compared with the key code transferred and stored in the storage unit MATCM in step 12q. Note that in FIG. 15, AMATCM indicates the first address of the storage section MATCH.

The code in the memory section CHR is the address (AMATCM+0
) if it matches the code stored in .

In step 12J, the code of key r8J of the numeric keypad 45 is set on the display section as the read character, and the process ends. Similarly, the address (AMATCM+
If it matches 1) and the result is 7, enter the code of key "5" on the numeric keypad 45 in step 12t.

If it matches the address (AMATCM+2'),
In step 12tL, enter the r2J code on the numeric keypad 45,
Similarly, if the content matches the address (AMATCM+11), press the numeric key 45 in step 16ct.
The code of the key "・" is set on the display section as the read character, and the process ends. If the code does not match any of the above codes, the process returns to step 12aK, and the code stored in the storage section CHH is read as it is and set on the display section, and the process ends.

According to the embodiment described above, the numeric keypad 45 can be set at any position in the standard key arrangement section 41.

In the above embodiments, the case where the cursor direction control key and the numeric keypad are assigned to arbitrary positions on the keyboard has been explained, but this is not limited to these types of keys, and any keys such as the program type keys can be assigned. It may be any key that is frequently used depending on the number or the like. This depends on which key code the data conversion means KCV outputs with respect to the storage location of the key code, and can be easily dealt with by changing this part.

In addition, in the embodiment, a case has been described in which data conversion is executed in the processing device 2, but in this case, a device having the same configuration as the processing device 2 is built into the board 1, and the converted data is processed on the keyboard l side. It may also be input into the device 2. This can be arbitrarily selected when configuring the computer device.

Furthermore, in the embodiment, a variable character display 1 such as a liquid crystal display is provided on each key arranged on the keyboard 1 or in the vicinity of each key, and when the assignment of each key is changed,
If the assigned characters, symbols, etc. are displayed, the operation will be even more effective.

In addition, in the embodiment, the number of key code storage units is 44. In the second embodiment, 9
However, this is for convenience of explanation, and this number is arbitrary. Also, the number of keys stored in each key code storage unit is 2.
The types can also be changed as necessary, and the present invention is not limited to these types. Furthermore, in the embodiment, the key code read from the keyboard 1 and the key code stored in the key code storage unit have been described as being the same, but it is sufficient that their coincidence can be ensured by some means. It doesn't have to be.
