Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a character input device suitable for use in, for example, workstations and word processors.

2. Description of the Related Art Conventional character input devices of this type include, for example, A, B,
When inputting the character string IC2..., switch the mode to "alphanumeric mode" and then enter A, B, C,...
It was necessary to input one string of characters.

Problems to be Solved by the Invention In other words, in the conventional character input device described above, since the character string is input after specifying the mode of the character to be input, for example, if you realize that the mode is different after entering the character string, The problem was that all the character strings that had been entered so far had to be erased.

The present invention solves these conventional problems, and even after inputting a character string, it is possible to switch modes and automatically change the characters in the input string to the characters that match the switched mode. The object of the present invention is to provide an excellent character input device.

Means for Solving the Problems In order to achieve the above object, the present invention provides an input mode in an apparatus having means for specifying an input character mode, means for inputting characters, and means for storing input key codes. It is equipped with means for switching character modes, means for storing codes assigned to keys for each mode, and means for outputting codes for each mode based on the stored codes. be.

Effect: With the above-described configuration, the present invention can manage codes according to modes for each key, and even if the mode is switched after inputting a character, the code can be changed to a code corresponding to the switched mode. can.

Embodiment (d) FIG. 1 is a block diagram showing a schematic configuration of a character input device that is an embodiment of the present invention.

In the figure, reference numeral 11 denotes a mode designation section in which the operator designates the mode of characters to be input. Reference numeral 12 denotes an input section through which an operator inputs characters. Reference numeral 13 is a key code storage unit that stores the input key code. Reference numeral 14 denotes a mode switching section, which switches the mode when the operator wants to change the mode after inputting characters. 15 is the key code management section,
When the mode is switched by the mode switching unit 14, it has a function of returning the key code corresponding to the switched mode to the mode switching unit 14.

16 is a key code storage unit 13 or a mode switching unit 14
This is a key code output unit that outputs the key code sent from.

Next, the operation of the above embodiment will be explained along with a specific example.

For example, specify "alphanumeric mode" in the mode specification section 11,
When four keys are pressed in order from the left on the second row from the bottom of the JIS keyboard on the input unit 12, JASDFJ is input. Then, the key code of this rA S D FJ is stored in the key code storage section 13 and outputted by the key code output section 16.

Here, when the mode switching section 14 switches the "alphanumeric mode" to the "hiragana mode", the key code management section 5 outputs "A→ta" and [S→tej.

The key codes rD→IJ and "F→S" are sent back to the mode switching unit 14. Then, the key code output section 16 outputs "Tateisu".

In this way, according to the above embodiment, for example, even though you originally wanted to input "vertice", you did not switch the mode from "alphanumeric mode" to "hirakana mode" and instead left it in "alphanumeric mode". In the past, if you had accidentally entered "rA S D FJ", you would have to delete the entered rA S D FJ, switch the mode to "hirakana mode J", and re-enter "tateisu". With just one operation of switching the mode to "hirakana mode", the input character string rA S D FJ can be automatically changed to "vertical chair".

Effects of the Invention As is clear from the above embodiments, the present invention has means for switching input character modes, means for storing codes assigned to keys for each mode, and means for outputting codes for each mode. Even if you enter the wrong mode, the entered character string will be automatically changed to the character string that corresponds to the mode you want to enter, without erasing it like in the past. Can be done.
