Further, 19 is a character pattern generation control section for generating characters to be displayed on the liquid crystal display section of the key top of the key 11, 20 is a key arrangement definition file in which information defining the input arrangement of the key 11 is stored, 21 Is a character code conversion control unit for displaying a character corresponding to the key code sent from the key input control unit 15 of the keyboard 1 on the display 3, and 22 is constantly monitoring the input code to backspace or delete. An input monitoring control unit that detects the error correction frequency by, for example, storing the character code input before when a code corresponding to
Reference numeral 3 denotes an error frequency storage unit for recording the error correction frequency detected by the input monitoring control unit 22, which constitutes the computer 2.

FIG. 2 is a plan view showing the appearance of the keyboard 1. 2A is a plan view showing the entire keyboard 1, and FIG. 2B is a plan view showing a display state of the upper plane of the key 11. As shown in the figure, a plurality of keys 11 are arranged on the keyboard 1, and characters or symbols that can be input by pressing the keys are displayed on the upper plane of the keys 11 by the liquid crystal. For example, in FIG.
"@" And "2" indicate keys that can be input.

The operation of this character input device will be described below. First, the key layout of the keyboard 1 is defined.
The user creates key layout definition data consisting of a key code output by pressing the key 11 of the keyboard 1 at the time of input, its key address, and a display character (or display character pattern) corresponding thereto, and defines this key layout definition. Store in file 20. This is composed of, for example, data as shown in FIG. 3, and as information of one key, a key code “65” output by pressing the key and an address of the key on the keyboard 1 are output. "0101" and the character "A" that can be entered with the key
Alternatively, it is composed of an instruction signal pattern such as a confirmation instruction.

The character pattern generation control section 19 generates a character pattern to be displayed on the liquid crystal display section of the key 11 based on the inputtable characters stored in the key layout definition file 20, and this character pattern, key code and key A key layout definition including an address is sent to the key layout control unit 13.
Here, the character pattern generation control unit 19 operates by executing the key layout setting command. The character pattern generation control unit 19 can also be activated by simultaneously pressing certain three types of keys on the keyboard 1.

The key layout control unit 13 that has received the key layout definition stores this information in the key layout conversion table 14. Then, the character pattern display control unit 12 refers to the key arrangement conversion table 14 to display the character pattern according to the set key arrangement on the liquid crystal display unit of the key 11. By the way, the key layout definition can also be obtained by inputting an initial layout setting command that generates data in which the initial state of the key layout is set. The key layout definition obtained by this is the one of the normal key layout prepared in advance.

The keyboard layout is initialized by the keyboard 1
It is also performed when the upper reset button 16 is pressed or when the power is turned on. This is because the keyboard layout control unit 13 has an initial keyboard layout information storage unit 17 of the keyboard 1.
This is done by referring to the key layout definition indicating the key layout in the initial state stored in the key layout conversion table 14 and using this. Since the keyboard layout conversion table 14 can be initialized by pressing the reset button 16, it is possible to easily restore the keyboard layout during the work.

When the user performs a key input after the input arrangement of the keys 11 is set as described above, the key input control unit 15 refers to the key arrangement conversion table 14 and sets the key code mode and the input key. The corresponding key code is Calculator 2
Send to. The character code conversion control unit 21 of the computer 2 sends an appropriate character from the sent key code to the display 3 according to the key code mode. Here, the input monitoring control section 22 constantly monitors the key code received by the character code conversion control section 21, and when a correction key code such as a backspace or delete key appears, it is sent before and after the correction. Memorize the key code you received. As shown in FIG. 4, this is stored in the error frequency storage unit 23 together with the frequency as error correction frequency statistical information.

Then, in the error correction frequency statistical information, when a frequency exceeding a predetermined threshold value occurs, the input monitoring control unit 22 corrects the key code before correction and the corresponding key code in the key layout definition file 20. Replace the subsequent key code. A key with a high frequency of error correction indicates that the key before correction and the key after correction are often mistakenly pressed. , The mistake of pressing these two keys is reduced. That is, by re-registering the replaced key layout definition, storing a new key layout definition in the key layout conversion table 14, and exchanging these two key layouts,
The input array of the keys 11 is in a state suitable for the user. This exchange of the key layout may be performed when the key layout definition file 20 is set to the key layout setting file change mode.

[0016]

As described above, according to the present invention, the key arrangement of the keyboard can be freely designed, and in addition, by repeating the key input, the key arrangement can be set in a state suitable for the user's key input. Since the key layout is changed, there is an effect that the keyboard layout can be made more suitable for the user.
