Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard device used as an input device such as an electronic computer or a word processor.

[Conventional technology]

FIG. 4 is a block diagram showing a schematic configuration of a keyboard device of this type. The keyboard device (1) includes a key portion (2) formed of a switch matrix and a code (bit information corresponding to a switch that is closed by pressing a key). ), And a shift control unit (4) that outputs a signal corresponding to the shift key, that is, a key for selecting kana or English letters for the same character key. , And an interface unit (5) that converts the code of the encoder (3) into a video signal according to the output of the shift control unit (4) and outputs the video signal, and the converted video signal is CR.
It is designed to be added to an output device (6) such as a T display device.

Here, the key part (2) is arranged differently depending on the use,
Normally, as shown in Fig. 5, a key group that combines numbers, letters, katakana, and special symbols is arranged in the center, and shift keys (10) to (13) are arranged at the lower end or side end. Has been done. And among the keys arranged in the center,
As shown in FIG. 6, a representative key (8) has an English symbol on the upper side, a kana on the lower side, an alphanumeric character on the left side, and a kana symbol on the right side.

As an actual input procedure by this keyboard device, for example, as shown in the flow chart of FIG. 7, first, in the step (101), one of the shift keys (10) to (13) is selected, and then the step If the character key is pressed in (102), the conversion operation is performed in step (103), and the video signal of the character corresponding to the shift key pressed out of the maximum four character symbols shown in Table 1 in the table below is displayed. It is added to the output device (6).

[Problems to be Solved by the Invention] Recently, one of the processings of Japanese documents is word processing, but most of the document creation is a method of inputting kana and converting into kanji. In this case, although the Kanji that matches the reading is searched from the Kanji dictionary, the character key should be pressed in Kana shift mode for this purpose, but if the character key is mistakenly pressed in the alphanumeric shift mode, it corresponds to the dictionary. Because there is no reading, Kanji cannot be converted, and you have to press the key again even though it has the same key position. This will be described with a specific example. First, in the Kana shift mode due to pressing the shift key (12) When each key of is pressed, "Keisanki" is displayed on the output device (6). However, in the Kana shift key mode, press the shift key (11) in the alphanumeric shift key mode. If each key is pressed, the alphanumeric code shown in the above table as Table 1 is generated and ": EXYG" is displayed on the output device (6). Therefore, this is a "calculator"
When I try to convert to Kanji, there is no corresponding character and it is not converted. In this case, cancel ": EXYG" with the backspace key, then switch to Kana shift key mode and try again. I had to press each key again.

The present invention has been made in order to solve the above-mentioned problems, and even if a key is pressed while the shift is mistaken, a keyboard device capable of converting a character in a correct shift mode without pressing the key again. Aim to get.

[Means for solving problems]

The keyboard device according to the present invention includes a storage unit that temporarily stores a symbol for each shift of a plurality of character keys pressed in the same shift mode as a shift code-to-character table.

[Action]

In the present invention, the character keys that are sequentially pressed in the same shift mode are stored as a table of shift code versus character, so even if the character key is pressed in the wrong shift mode, the shift key is only pressed again. Are converted into different characters all at once, and as a result, unnecessary work of pressing the same key position again is unnecessary.

〔Example〕

FIG. 1 is a block diagram of an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 4 denote the same elements. Then, between the encoder (3) and the shift control unit (4) and the interface unit (5), a shift / character storage for temporarily storing in advance a symbol for each shift of the character key as a shift code-to-character table. The difference from FIG. 4 is that a part (7) is provided.

FIG. 2 is a detailed configuration diagram of the shift / character storage unit (7), which is a storage area N ₁ for storing the shift code and the character of the character key pressed first as a table 2, and the second pressed key. Storage area for storing character key shift codes and characters
It has a storage area of 30 to 40 characters, such as N ₂ .

The operation of the embodiment configured as described above will be described according to the flowchart of FIG.

First, in step (111), shift keys (10) to (13)
If one of the characters is selected and then the character keys are sequentially pressed in step (112), all the characters of the shift selected in step (113) and the characters of the other shifts are read from the interface section (5). At the same time, the video signal of the character corresponding to the selected shift is added to the output device (6) at the same time as the data is written in the shift / character storage unit (7). In this case, each time the character key is pressed, the character code is written in the order of the storage areas N ₁ , N _2, ...

Next, in step (115), it is confirmed that all the necessary characters have been input, and in step (116) it is checked whether or not the desired character is displayed on the output device (6). If is displayed, check in step (117) whether there are any other characters to be input, and if there is another, repeat the operation of steps (111) to (116), and If it is not necessary to enter characters in, the input operation ends.

On the other hand, when it is determined in step (116) that the characters other than the desired character are displayed on the output device (6), the desired shift key is pressed again in step (118). At this time, the character code and the shift code corresponding to the newly pressed shift key are read from the shift / character storage unit (7) and programmed so as to be added to the interface unit (5). Then, in the next step (119), the character input operation is ended when the desired character is displayed on the output device (6), or the input operation of another character is started.

Thus, according to this embodiment, the shift remains erroneous.
Even if 30 to 50 character keys are pressed, it is possible to convert the character to the correct shift mode by simply pressing the desired shift key again when the output device finds that the shift is incorrect. Also, by pressing the Kanji conversion key in this state, the desired Kanji can be obtained.

In the above embodiment, when the shift is determined to be incorrect, the Kanji conversion key is pressed after changing to the correct shift, but when the Kanji conversion key is pressed, only the Kana conversion key is pressed. Then, the character code corresponding to the kana shift can be read and programmed to be stored in the shift / character storage section (7) so that the kanji conversion can be performed with one key touch without pressing the kana shift key. Become.

〔The invention's effect〕

As is clear from the above description, according to the present invention,
Since the shift / character storage unit for storing in advance all the character codes corresponding to the pressed key is provided, the re-input work due to the mistaken selection of the shift key is unnecessary. Further, since the conversion can be performed only by selecting from the character code stored in the shift / character storage unit, there is an effect that the processing is fast. As a result, the VDT (Visual Display Terminal) reduces input time and causes frustration due to pressing the same key again.
The mental distress of work can be reduced.

The existence of Japanese Patent Application Laid-Open No. 61-231624, which was filed about 1 year and 4 months ahead of this invention, was found. In contrast to the invention of this earlier application, the invention of claim 1 has existed conventionally. By utilizing the shift key, it is possible to realize the correction to the target character string, and in the invention of claim 2, the utilization of the kanji conversion key that has been existing in the past can be performed to the target character string. Correction and Kanji conversion can be realized, and there is an advantage that it is not necessary to increase the number of function keys for issuing a character string correction request.
