Description

[Detailed Description of the Invention] The present invention relates to a character input device for an information processing system.

Recently, there has been an increase in the number of devices that process kanji in the field of information processing systems in Japan, and their convenience is being recognized compared to devices that could only handle alphabets, kana, and numerical colors.

This will be explained using kanji as an example of input information.

It is said that 2,400 characters are required for articles based on commonly used kanji and newspaper articles, 4,500 characters are required for general books and magazines, and over 10,000 characters are required for dictionaries and encyclopedias, so one key is required. Even if you assign 8 characters to , you will need at least 300 keys, and at most 1000 or more keys.

Traditionally, such character input devices were operated by people who had been trained over a long period of time, but as information processing using kanji became more advanced, they were operated by ordinary people with little training, so-called operators. Even amateurs will have the opportunity to operate the system, but it takes a considerable amount of time to find the desired key among the large number of keys as described above.

Since the character input device for inputting multi-character type information such as kanji handles a huge number of characters, the number of keys of the natural character input device increases, making the device expensive.
Moreover, it has drawbacks such as difficulty in finding the characters when using it.

Therefore, in the past, one key was used to handle multiple characters, and other means were used to specify one of the characters, thereby achieving a certain degree of miniaturization and cost reduction of the device. However, the drawback of making it difficult to find text remained the same.

FIG. 1 shows an example of a conventional multi-character input device.

The character input device 1 has keys 2 (see FIGS. 21 to 24 in FIG. 2) arranged on its head, each displaying, for example, eight types of Chinese characters.

The key 4 is made up of eight pieces, and by a combination of one key 2 and one key 4, one of the eight types of kanji above the key of the key 2 is selected, and the corresponding kanji is selected. A code is punched onto the paper tape by a paper tape punch 3.

At this time, even though the kanji are arranged in the order of radicals arranged according to a certain rule, searching for one kanji from a key of 100 requires a high degree of skill. .

For these reasons, operators tend to make mistakes.

This type of mistouch includes ■ When the operator recognizes that he made a mistouch ■ When the operator makes a mistouch but does not know how he made the mistake ■ When the operator made a mistake but is not aware of the mistake There are three cases.

In the case of ■, the operator can correct it immediately.

In case (2), the operator is not at ease, so the correct input is transmitted to a subsequent device, such as an output device.

In the case of ■, it is unclear how the mistake was made, so we must first analyze the details of the mistake.

The purpose of this proposal is to enable efficient processing of this problem.

Conventionally, for this purpose, a method has been attempted in which an operator directly reads the punch marks on the paper tape to determine the nature of the mistake.

If the structure is such that the perforation cannot be directly read,
For example, a method has been proposed as in Japanese Utility Model Application Publication No. 53-163200, in which the tape is moved back to a position where the perforation code can be confirmed.

Furthermore, as in Japanese Patent Publication No. 53-46530, a method has been adopted in which an indicator is provided and instead of reading the code on the tape, the bit code displayed on the indicator is checked.

However, with this method, the operator must directly read the perforation code, or bit code, and must either memorize most of the bit codes or prepare a bit code table. It won't happen.

Furthermore, the method disclosed in the above-mentioned Japanese Utility Model Publication No. 53-163200 has the problem that it takes time to retract and feed out the tape.

The present invention is based on these points, and the principle thereof will be explained using FIG. 3.

4 in Figure 3 is the 8 pieces shown in Figure 1 (9 pieces in the figure for convenience)
2 indicates the left-hand shift key, and 2 indicates an arbitrary part of a group of keys displaying kanji or the like.

Now, assume that you have made a mistake in pressing the arbitrary key 31 in the second group of keys.

In this case, the mistouch is 8 around the key 31 that should be pressed.
It is common to think that the problem occurred in one of the two keys.

In the case of a one-handed shift key system, there are key combinations for both hands, so a total of 64 combinations need to be considered.

However, if there is a mistouch, for example, the key 3 that should be pressed
Normally, to determine whether the mistouch occurred on the left, right, top, or bottom of 1,
This can be determined intuitively.

(If you don't know, you won't know that there was a mistouch.)

Therefore, in the end, by checking 2 to 3 keys, it is possible to know the details of the mistouch.

In this case, when the operator recognizes that he or she has made a mistake, the operator has to perform the input operation again, and from the result it is immediately possible to determine whether the input was correct or incorrect. By simply operating a few keys, it was possible to learn the details of the mistake in kanji (letters).

The following will explain the embodiments shown in the figures.

FIG. 4 is a block diagram showing an example of an input device according to the present invention.

In the figure, 41 is a key switch circuit that generates a corresponding signal every time keys 2, 4, etc. in FIG. Store n character signals.

44 is a matching circuit, and 45 is a confirmation key circuit, which is operated by pressing a confirmation key (not shown).

46 is an alarm such as a buzzer and lamp, and 47.48 is a gate circuit.

When keys 2 and 4 in FIG. 1 are operated to input characters and symbols, corresponding signals are generated from the key switch circuit and sent to gate circuits 47 and 48.

Since the gate circuit 47 is open when the confirmation key circuit 45 is in the OFF state, the signal from the key switch circuit 41 passes through the gate circuit 47 to the puncher 42 and is punched into the paper tape.

The same signal as the signal punched by the puncher 42 is stored in the temporary memory 431.

On the other hand, the gate circuit 48 is closed when the confirmation key circuit is OFF.

As the drilling operation progresses in this way, if the operator recognizes a mistouch for some reason, the confirmation key circuit 45
Press the confirmation key (to make it easy to judge this status, it is preferable to use the confirmation key as a lamp display material)
.

Then, the gate circuit 47 is closed and the key switch circuit 4 is closed.
The signal from 1 is interrupted from being punched by the puncher.

Then, the other gate circuit 48 is opened so that the signal from the key switch circuit 41 is directed to the matching circuit 44.

Once you're prepared in this way, try pressing the key that corresponds to the correct letter, that is, the key that corresponds to the correct letter that you should have entered, rather than the key that seems to have been punched by a previous mistouch.

Then, the signal reaches the matching circuit 44 from the key switch circuit 41 via the gate circuit 48.

Since the latest data stored in the temporary memory 43, that is, the signal of the mistouched character is always transmitted to this matching circuit, the two are compared.

If the two match, the alarm 46 is activated to notify the operator, and at the same time a reset signal is sent to the confirmation key circuit 45.
is transmitted to.

This determines that the operator's mis-touch was a mistake, and the next drilling operation begins.

If the alarm 46 does not operate, it is confirmed that there has been a mistouch, and after reversing the tape by one character with the puncher 42, the confirmation key circuit 45
is reset and an erasure signal is transmitted from the key switch circuit 41 to the puncher 42 to erase the code punched by a mistouch and re-input the correct character.

The explanation of the device regarding the puncher retraction function and the erasing function in this case is completely omitted in FIG. 4, but since it is a well-known general technique, it will not be mentioned here.

To find out the content of the mistouch, try pressing the keys around the correct character key as explained in FIG.

If the alarm 46 is activated, it will be known that the character just pressed was entered incorrectly.

Therefore, by operating the character keys around the correct character key one after another until the alarm is activated, the content of the mistouch can be easily determined.

However, as explained in FIG. 3, the desired result can be easily obtained by operating a few keys.

As explained above, the main feature of the present invention is that characters can be confirmed on the screen of the character input device.

Also, since it can be confirmed not with a bit code but with ordinary characters that can be read by an operator, even an untrained operator can easily perform post-processing of mistouches.

Furthermore, since the present invention can be achieved with a simple device without adding any special indicators, it is possible to greatly contribute to reducing the size of the input device for each type of character information while suppressing the increase in price.

The above explanation assumes that paper tape is used, but the same applies to magnetic tape, and it can also be used for so-called direct entry type input devices that send signals directly to the control section of the device without going through the tape. It is obvious that it can be applied.

Furthermore, the present invention can also be implemented with other types of input devices that do not use a shift key, such as a one-sided input device that does not use a shift key, or a tablet that does not use a key.

Furthermore, the present invention is effective not only when a touch is missed, but also when an operator temporarily suspends work and then checks how far the input has been made when restarting.

Furthermore, it is possible to handle input devices not only for Japanese languages such as kanji but also for other languages in the same way.
