Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a character input device.

[Summary of the Invention] The present invention makes it possible to easily input characters and symbols in a word processor, for example, by switching between the output of a keyboard and the output of a character recognition device and inputting the same to a front-end processor. be.

[Prior Art] A Japanese word processor is configured as shown in FIG. 4, for example.

That is, in the same figure, (10) is the main body of the word processor, (31) is the full keyboard, and (32) is the printer.
) is connected to the main body (10) through the connectors (27) and (28).
)It is connected to the.

Then, when the power switch (not shown) is turned on, R
By the loader program of OM (12), FD D
A word processor program is read from a floppy disk (not shown) mounted on (1B), and this program is sent to R through FDC (19).
A M (13).

In this case, the word processor program loaded into the RAM (13) is a Japanese front end processor (hereinafter referred to as rFEP), as shown in the figure.
(14), and a processing program (15) for editing, displaying, and printing the output of this F E P (14).

Further, the FEP (14) has a dictionary and a grammar book, and has character codes of characters (kana, kanji, numbers, alphabets, etc.) and symbols intended for the output signal Sk of the keyboard (31), such as JIS It converts it into code.

Then, when the user inputs from the keyboard (31), the output signal Sk is taken in through the interface (17), converted into the JIS code of the target character or symbol by F E P (14), and the converted The JIS codes obtained are sequentially written into the document RAM (16) as document data.

At this time, part of the document data in RAM (16) is transferred to the display memory (21), and the data in this memory (21) is transferred to the display controller (21).
22), and this read data is supplied to, for example, a CRT display (23), on which characters input from the keyboard (31) and characters and symbols converted by the FEP (14) are displayed.

Furthermore, when an instruction such as editing or printing is given from the keyboard (31), the processing program (15) causes the RAM (1
The document 6) is edited, saved to a floppy disk through the FDD (18), or supplied to the printer (24) through the interface (24) and printed out.

The above is the outline of the Japanese word processor.

[Problem to be solved by the invention]

By the way, in Japanese word processors, F E
Kanji conversion according to P (14) is essential, and the conversion mode or input mode during this kanji conversion is basically divided into 1, character input kanji conversion mode 2, and code input kanji conversion mode.

That is, in the case of mode 1, the keyboard (31
) mode key to set the input mode to kana input mode. Then, when you press the key ``ka, n, shi'' and then press the conversion key, the ``kanji'' is converted into a ``kanji''.

In the case of the second mode, the input mode is set to the JIS code input mode using the mode key of the keyboard (31). And the JIS code for "Kanji" is
r3441.3B78", so "3.4.4.1",
When you press the keys ``3, B, 7, A'', these are converted to ``kanji''.

In this way, there are two main methods for converting kanji using F E P (14), but when inputting ordinary sentences, it is common to use the first conversion mode. , you can type fairly quickly.

However, when a kanji is used infrequently or has a special reading, for example, when entering an address or name into an address book, it may be difficult to know the reading (sound or precept) of the kanji. Alternatively, there are some symbols such as ", °8, [, ☆", etc.] that cannot be directly keyed in from the keyboard (31).

Then, in such a case, check the JIS code table and find the relevant JIS code.
Input this JIS code in the code input mode of Section 2 (kanji conversion).

ii Look up the reading in a Kan-Japanese dictionary and enter the reading in the Kana input mode for item 1.

You will have to choose one of these methods.

However, when using the method in item i, it takes time to search for the desired kanji when looking up the JIS code table, and in some cases, the desired kanji may be overlooked.

Also, when using the method in section ii, the same as the method in section 1,
It still takes time and effort. Moreover, even if you know the reading and input it into the word processor, if the reading is not registered in the dictionary of F E P (14), kanji conversion will not be possible.

This invention attempts to solve these problems.

(Means for solving the problem) As mentioned above, the reason why characters and symbols whose pronunciations and JIS codes are unknown must be input into a word processor is because such characters and symbols are not written in the input manuscript. This is when you type while looking at the characters and symbols. Therefore, even if you don't know the pronunciation or JIS code, you know the characters and symbols themselves.

This invention focuses on such points.

That is, in this invention, an output signal equivalent to a keyboard output signal is extracted from a handwritten character recognition device,
This extracted output signal is supplied to the front end processor in place of the output signal from the keyboard.

[Effect]

You can easily enter characters and symbols whose readings or character codes you do not know.

[Example] In FIG. 1, (40) represents a real-time handwritten character recognition device, and (41) represents a tablet for inputting handwritten characters.

For example, as shown in FIG. 2, this tablet (41) includes a touch panel (42) and a touch panel (42).
Pen (42) for inputting desired characters and symbols
and has. Further, for example, at the top of the panel (42),
It has areas 5TRT and XEND for instructing the device (40) to start and end character recognition.

Furthermore, (45) is a recognition circuit, which includes a tablet (
The pen (43) is supplied with the output of the panel (41).
The characters or symbols written on the panel (42) with the pen (43) are recognized in real time between when you press area 5TRT and until you press area XEND in 2), and the recognition result is shown in Figure 3A. character code, for example JIS
It is output as a code signal Sa.

Also, (46) is a conversion circuit, which is a recognition circuit (45)
The output signal Sa is converted into a signal sb as shown in FIG. In other words, the output signal Sk of the keyboard (31) only indicates which key was pressed, and for example, even if the "1" key was pressed, it does not indicate "1".
” signal of JIS code '2331J' is not output.

Therefore, the conversion circuit (46) converts the output signal Sa into a signal Sd equivalent to the signal Sk when a key on the keyboard (31) is pressed in accordance with the JIS code.

Further, when the mode key of the keyboard (31) specifies the JIS code input mode, a signal Se equal to the signal output from the keyboard (31) is added in front of the signal Sd, and the keyboard (31) When the mode key specifies kana input mode, the keyboard (31)
A signal Sf, which is equal to the signal output from the signal Sd, is added after the signal Sd. In this way, the signals Se, Sd,
A signal sb containing Sf is output from the conversion circuit (46).

Further, the conversion circuit (46) also outputs a signal Sc which becomes, for example, "'1" during the period of the signal sb, as shown in FIG.

The signal sb is supplied to the switch circuit (47), and the signal Sk from the keyboard (31) is supplied to the switch circuit (47) through the connector (48). Furthermore, the signal Sc is supplied as a control signal to the switch circuit (47), and the output signal of this switch circuit (47) passes through the connector (49),
27) to the word processor main body (10).

According to such a configuration, the switch circuit (47
) is in the state shown in the figure due to the signal Sc, so the keyboard (
The output signal Sk of 31) is supplied as is to the main body (10), and therefore, as explained in FIG. 4, kanji conversion and the like are performed as a word processor.

However, if you touch area 5TRT of panel (42) with pen (43), write a character or symbol on panel (42), and finally touch area
3), the characters or symbols written on the panel (42) are recognized by the recognition circuit (45), and an output signal Sa indicating the recognition result in JIS code is output as shown in FIG. 3A.

For example, if you write "Kanji" on panel (42),
Its JIS code is r3441. , r 3B7A
A signal Sa indicating J is output.

Then, the signal Sa is converted by the conversion circuit (46) into the i word Sd when the key corresponding to 8 on the keyboard (31) is pressed. In this case, the signal Sa is "Kanji"
JIS code r3441. , r 3B7A J, so the conversion circuit (46) outputs the signal Sd when the keys on the keyboard (31) are pressed in the order of "3.4.4.1", "3, B, 7, A". be done.

Also, before and after this signal Scl, a signal Se is provided.

Sf is added.

At this time, the switch circuit (47) is connected in the opposite state to that shown in the figure by the signal Sc, so the recognition circuit (47)
The signal sb from 46) is supplied to the interface (I7) through the switch circuit (47).

Then, this signal Sc, seen from F E P (14), sets the mode key of the keyboard (31) to the JIS code input mode, and then sets the key of the keyboard (31) to "3".
．． Since it is equivalent to the signal Sk when pressing "4.4.1", "3, B, 7, A" in this order, F E P (14) can be regarded as the input of the signal Sc according to the JIS code in the above 2 items. The signal Sc is converted into the JIS code of "Kanji" and written into the RAM (16).

Since there is a signal Sr at the end of the signal sb, this signal Sr causes the F E P (14) to
The input mode of 1) is now considered to be the kana input mode. In addition, the switch circuit (4
7) is connected to the state shown in the figure.

Therefore, input from the keyboard (31) becomes possible again from now on.

Thus, according to the present invention, when a character or symbol is written on the panel (42), that character or symbol is recognized and converted into a character code, and this is replaced by the output of the keyboard (3) as F E P (14). ), you can easily input characters and symbols even if you do not know their pronunciation or character code. For example, when entering an address or name into an address book, this can be done easily and quickly.

Furthermore, it is only necessary to add a handwritten character recognition device (40) to a conventional word processor (10).

In addition, in the above, the handwritten character recognition device (40) is
It can also be in the form of an adapter for a word processor (10) as shown in the figure, or as an adapter for a word processor (10).
0). Also, a tablet (4
1) and the configuration of the recognition circuit (45) are also arbitrary.

Furthermore, F E P (14) is F in a language other than Japanese.
The present invention is effective in the case of EP, that is, FEP of a language such as Chinese, which requires not only input by reading but also input by character code.

However, you can easily enter this. For example, when entering an address or name into an address book, this can be done easily and quickly.

Furthermore, it is only necessary to add a handwritten character recognition device (40) to a conventional word processor (10).
