Description

Description: TECHNICAL FIELD The present invention relates to a character input device suitable for use in, for example, a workstation or a word processor.

2. Description of the Related Art Conventionally, when inputting a character string of A, B, C, ..., for example, this type of character input device switches to "alphanumeric mode" and then switches between A, B, C, ... I needed to enter a string.

Problems to be Solved by the Invention In other words, in the above-described conventional character input device, since the character string is input after specifying the mode of the character to be input, for example, if the user notices that the mode is different after inputting the character string, All strings entered so far must be erased,
There was a problem.

The present invention solves such a conventional problem. Even after inputting a character string, the mode can be switched, and the character of the input character string can be automatically changed to a character suitable for the switched mode. It is an object of the present invention to provide such an excellent character input device.

Means for Solving the Problems In order to achieve the above object, the present invention provides an apparatus including a mode designating unit for input characters, a unit for inputting characters, and a unit for storing an input key code. Means for switching character modes, means for storing codes corresponding to key codes for each mode, and code corresponding to input characters while switching to the mode corresponding to each mode when the mode of input characters is switched And a means for outputting the changed data.

Operation According to the present invention, the code according to the mode can be managed for each key by the above-mentioned configuration, and even if the mode is switched after the characters are input, the code corresponding to the switched mode can be switched. Can be.

Embodiment FIG. 1 is a block diagram showing a schematic configuration of a character input device according to one embodiment of the present invention.

In the figure, reference numeral 11 denotes a mode designating unit, which designates a mode of a character to be input by an operator. Reference numeral 12 denotes an input unit for the operator to input characters. Reference numeral 13 denotes a key code storage unit that stores the input key code. 14
Is a mode switching unit, which is switched by the switching unit 14 when the operator wants to change the mode after inputting characters. Reference numeral 15 denotes a key code management unit, which has a function of returning a key code corresponding to the switched mode to the mode switching unit 14 when the mode is switched by the mode switching unit 14. Reference numeral 16 denotes a key code output unit that outputs a key code transmitted from the key code storage unit 13 or the mode switching unit 14.

Next, the operation of the above embodiment will be described together with a specific example.

For example, specify "alphanumeric mode" in the mode specification section 11,
When four keys are sequentially pressed from the left in the second row from the bottom of the JIS keyboard on the input unit 12, "ASDF" is input. And
This “ASDF” key code is stored in the key code storage unit 13 and output by the key code output unit 16.

Here, when the “alphanumeric mode” is switched to the “hiragana mode” by the mode switching unit 14, the key code management unit 5 sends “A → ta”, “S → te”, “D → ye”, “F → su”. Are returned to the mode switching unit 14. Then, the key code output section 16 outputs “Tatesu”.

As described above, according to the above-described embodiment, for example, although the user originally wants to input “Tatesu”, without changing the mode from the “alphanumeric mode” to the “hirakana mode”, the “alphanumeric mode”
If you entered it as it was, in the past it was necessary to delete the entered "ASDF" once, switch the mode to "Hiragana mode" and enter "Taitasu" again. On the other hand, with just one operation of switching the mode to “hirakana mode”, the entered character string “ASD
"F" to "Tatesu".

As is clear from the above embodiments, the present invention provides means for switching the mode of input characters, means for storing a code corresponding to a key code for each mode, and Means for switching to a code according to the mode and changing the input characters to the corresponding code and outputting the code, even if the mode is incorrectly entered, the mode to be input is switched and each mode is changed. It is possible to switch to a code according to the above and automatically change the character string corresponding to the mode to be input without erasing the input character string as in the past.
