Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical character reading device (OCR) used by connecting to various data processing devices (computer body) including a document creating device, an automatic translation device, etc., and a system device such as a filing device. ) Etc. regarding the input device.

[0002]

2. Description of the Related Art Generally, a keyboard is frequently used as an input device of a system device such as a data processing device or a filing device, but it takes a long time to get used to the key input operation of the keyboard.

Therefore, as an input means for assisting a key input operation with a keyboard, an OCR for optically reading and inputting a handwritten or printed character or symbol, a handwriting such as a handwritten character directly on a board surface is a group of pressure sensitive sensors. There has been proposed a device including a tablet input device or the like that detects a character by hand and recognizes a character corresponding to the handwriting and inputs the character.

For example, there are the following devices. (1) Recognize the characters input by handwriting from the tablet, determine the recognized characters, convert them into output codes that can be distinguished from the output codes from the keyboard, and output them from the output code and keyboard via an adapter. A character input device that integrates with the output code of the above and outputs to the control processing main body (for example, see Japanese Patent Laid-Open No. 61-223974).

(2) An information input device in which a handwritten OCR is connected to an information input device capable of inputting information from a voice or a keyboard, and when inputting unreadable Chinese characters etc., handwriting input by the handwritten OCR is possible. (See, for example, Japanese Utility Model Laid-Open No. 62-62368).

(3) By recognizing an instruction input by handwritten characters or voice by replacing the key input of the keyboard or the push button input on the panel, the instruction is registered in advance in the registration table corresponding to the recognition result. An information processing device for selecting a process (see, for example, Japanese Utility Model Laid-Open No. 62-187340).

(4) A keyboard for outputting character and numeral codes by pressing a key, and a hand scanner and an OCR character read by the hand scanner for generating character and numeral codes and outputting from the keyboard. A personal computer input device that has a character and number recognition unit that outputs a logical sum and treats the input from both the keyboard and the hand scanner as the same input (for example, Japanese Patent Laid-Open No. Sho 64-64).
-50114).

[0008]

However, each of the above-mentioned devices has the following problems. (1) The system of the output code is different for the character input of the tablet and the keyboard, and the control processing body that receives the output code has to perform the processing to determine the output code of both, so the processing efficiency is improved. Not only is it lowered, but it cannot be used as is in conventional general data processing devices. Moreover, since only the characters can be input by handwriting on the tablet and various control information cannot be input like the keyboard, the tablet cannot be used completely in place of the keyboard.

(2) Since voice input, keyboard input, and handwritten OCR input must be input to the main body through separate input interfaces and different recognition processing must be performed respectively, the structure and program of the data processing apparatus main body becomes complicated. It has no versatility.

(3) The pre-registered processing can only be selected by handwritten character input or voice input, and various information cannot be freely input as in the case of key input using a keyboard. Limited to special purposes.

(4) Inputs from the keyboard and the hand scanner are only character and numerical codes, and other control codes cannot be input. In addition, in general data processing devices such as personal computers and word processors, the character and numerical codes are not input from the keyboard interface, and the key pressing position (key code)
Since the ON / OFF information is input and the process of converting the ON / OFF information into a character or numerical code or control code is performed in the main body, inputting the character and numerical codes is not versatile.

Further, since the logical sum of the codes output from the keyboard and the hand scanner is output, there is a possibility that simultaneous input by the both will occur in the data processing apparatus main body.

As described above, all of the above-mentioned conventional input devices mainly use the key input by the keyboard so that the OCR or the tablet input device can be used as an auxiliary input device. To increase the number of means, there has been a problem that the configuration of the data processing device main body side is complicated, the processing load is increased, or the versatility is lacking.

Further, it has not been possible to input all kinds of information using an input device other than the keyboard, as with the keyboard. In particular, no consideration has been given to inputting Chinese characters in the same way as a keyboard, or efficiently outputting information such as characters including Chinese characters to the main body of the data processing device to improve information input efficiency.

The present invention has been made in view of the above points, and regarding the characters including the characters printed by the OCR or the tablet input device or the handwritten Chinese characters and various control information, the input information is operated by the key operation from the keyboard. The input can be handled in exactly the same way, and the versatility of input operation, flexibility,
It is another object of the present invention to provide a versatile input device that can be used with a great improvement in efficiency and can be used without changing the data processor main body side. And
In particular, it aims to improve the input efficiency of Chinese characters and the continuous input efficiency of the same character type.

[0016]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an information input means for inputting information such as printed or handwritten characters, and an identification code for recognizing the input information. Input information recognition means for outputting, keyboard operation code creation means for converting the recognition code into a keyboard operation code, keyboard signal creation means for converting the keyboard operation code into a keyboard signal corresponding to the system device, and the keyboard signal Keyboard signal output means for outputting to a system device such as a data processing device via a keyboard interface.

The keyboard operation code creating means is a table of keyboard operation codes corresponding to the kanji input operation, means for judging whether or not the recognition code from the input information recognizing means is kanji, and kanji. And a means for converting the recognition code into a keyboard operation code corresponding to the input operation of the Chinese character when using the above table.

Further, the keyboard operation code corresponding to the input operation of the kanji to be input may be the keyboard operation code corresponding to the kanji input operation by the JIS code. Further, means for judging the character type of the information recognized by the input information recognition means, means for recording the judged character type, means for recording the character type of the character output as a keyboard signal, and both of them. Means may be provided for managing the change of the input mode depending on the character type based on the character type information recorded in each means.

[0019]

When the input device according to the present invention inputs and recognizes information such as printed or handwritten characters, the recognition code is converted into a keyboard operation code, and the keyboard operation code is converted into a keyboard signal corresponding to the system device. (Key code and its ON / OFF signal) and output to a system device such as a data processing device via a keyboard interface. Then, it is determined whether or not the recognition code from the input information recognition means is a kanji, and if it is a kanji, a keyboard operation corresponding to that kanji input operation is performed using the table of keyboard operation codes corresponding to that kanji input operation. Convert to code.

Therefore, on the side of the system device, it is possible to process printed or handwritten information such as kana or alphanumeric characters or kanji in exactly the same way as information input by key operation from the keyboard. Therefore, it is possible to connect and use the various data processing device main bodies (system devices) using the conventional keyboard without changing the keyboard interface.

If the keyboard operation code corresponding to the input operation of the kanji to be input is changed to the keyboard operation code corresponding to the kanji input operation by the JIS code, various data processor main bodies (system devices) using the conventional keyboard Can be used by connecting to the keyboard interface without any change, and the keyboard operation code can be efficiently output to the system unit side by the commonly used JIS code.

Further, when the character type of the information recognized by the input information recognizing means is judged, the character type is recorded, and the character type of the character output as the keyboard signal is recorded, and the recorded character type of each is recorded. By managing the change of the input mode by the character type by the information, even if the information of the same character type is continuously input, the keyboard operation code for changing the input mode does not have to be output each time. As a result, it becomes possible to efficiently input information without outputting an extra keyboard signal to the system unit side.

FIG. 4 is an explanatory view of the keyboard operation code creation table stored in the keyboard operation code creation information storage unit 7, FIG. 5 is a view showing an example of a storage format of the keyboard operation code creation information, and FIG. 6 is FIG. 5 is a diagram showing an example of a storage format of keyboard signal creation information in a keyboard signal creation information storage unit 9 of FIG. As shown in FIG. 4, the keyboard operation code creation table stores a table for storing information such as characters and symbols, a table for storing special mark information indicating control information, and a keyboard operation code corresponding to Kanji input operation. It consists of a table.

The keyboard operation code creation information consists of recognition data and keyboard operation data, and the recognition data is information such as characters and symbols corresponding to each key on the keyboard (for example, "0", "A", "A", etc.). ) And a special mark (eg "Space""Upcursor""Linefeed""Shift")
A mark indicating an instruction function such as "two-byte / one-byte" and kanji information (for example, "A", "I", "Right", etc.), and keyboard operation data is a keyboard operation for inputting each of those information. Information.

For example, as keyboard operation data corresponding to the recognition data of the Chinese character "A", a key operation for starting the input of a Chinese character by a code and a key for inputting the JIS code '3021' of the Chinese character "A". The operation data, that is, the operation of the '3' key, the operation of the '0' key, the operation of the '2' key, the operation of the '1' key, and the key operation for ending the kanji input by the code are stored. ing.

As shown in FIG. 5, the keyboard operation data for inputting "0" corresponding to the recognition data "0" has the number of key operations = 2 (two key operations are required as the operation data control information. "," And a pointer to the "alphanumeric" key for keyboard signal creation information indicating the operation of the "alphanumeric" key, and a "0" key for the keyboard signal creation information indicating the operation of the "0" key. It consists of a pointer and.

Further, the keyboard operation data for inputting "A" corresponding to the recognition data "A" is key operation number = 2 as operation data control information and keyboard signal creation information indicating operation of the "Katakana" key. From the pointer that points to the "Katakana" key and the pointer that points to the "3" key in the keyboard signal creation information that indicates the operation of the "3" key (since the "A" key also serves as the "3" key) Become.

Similarly, as for the special mark, as shown in FIG. 4, the keyboard operation data for inputting the "up cursor" corresponding to the recognition data indicating the "up cursor" is the number of key operations = operation data control information. 1 (not shown in FIG. 4) and a pointer pointing to the "up cursor" key in the keyboard signal creation information indicating the operation of the "up cursor" key.

The keyboard signal generation information is composed of keyboard signals when each key is pressed and released, as shown in FIG.

Next, the operation of each part of the input device 1 shown in FIG. 3 will be described. First, the character recognition unit 5 outputs a pointer pointing to keyboard operation data corresponding to the corresponding character in the keyboard operation code creation information storage unit 7 as a result for the recognized character.

As shown in FIG. 5, this keyboard operation data has the number of key operations as the operation data control information and the operation information of the key as the operation data. The number of key operations is the recognized character or control information. Is the number of key operations when the special mark indicating is actually input from the keyboard, and the operation data corresponds to the input operation procedure, and key operations (types of input keys) are arranged in the order of key operations. A pointer pointing to the corresponding key stored in the keyboard signal creation information storage unit 9 is set in the key operation information.

When the keyboard operation code creating section 6 receives the pointer from the character recognizing section 5, it retrieves the number of key operations and the operation data corresponding to the pointer, and operates the key operation information (keyboard in order from the operation data by the number of key operations). A pointer to signal creation information) is input and output to the keyboard signal creation unit 8.

The keyboard signal generation unit 8 sequentially outputs the code of the corresponding key and the keyboard signal indicating the pressing and releasing of the key to the keyboard signal output unit 10 by the pointer from the keyboard operation code generation unit 6. Then, the keyboard signal output unit 10 uses the keyboard I / F cable 2
The keyboard signal is output to the system unit 3 via.

Next, the process of inputting information by the input device 1 will be described with reference to the flowchart of FIG. First,
When a character or a special mark is input from the character input unit 4, it is sent to the character recognition unit 5, and the character recognition unit 5 performs the recognition process and sends a pointer to the keyboard operation code creation unit 6.

Upon receiving the pointer, the keyboard operation code creating section 6 obtains the key operation number Kt from the keyboard creation code information for the corresponding data pointed to by the pointer, and sets the key operation extraction number Kn to 0. The number Kt of key operations is compared with the number Kn of key operations taken out, and if they are equal, it is judged whether or not the input is completed. If YES, the process ends. If NO, the character input process by the character input unit 4 is repeated.

On the other hand, if Kt and Kn are not equal, 1 is added to Kn by the keyboard signal creating section 8 to obtain the operation of the Kn-th key from the operation data, and the pointer pointed to is pressed from the keyboard signal creation information. When the keyboard signal is obtained, the keyboard signal output unit 10 outputs the keyboard signal.

Further, when the release-time keyboard signal is obtained from the keyboard signal generation information by the pointer pointed to by the operation of the Kn-th key and output by the keyboard signal output unit 10, the process returns to the process of comparing Kt and Kn, and Kt and Kn. The process is repeated until is equal.

Next, an example of actual character input processing in the input device 1 will be described with reference to the block diagram of FIG. First, the case of inputting the katakana “A” will be described. When the character input unit 4 reads the katakana “A” written on the sheet and sends it to the character recognition unit 5, the character recognition unit 5 recognizes the katakana “A” and recognizes the data “A” for recognition of keyboard operation creation information. The pointer pointing to is sent to the keyboard operation code creation unit 6.

Then, the keyboard operation code creating section 6
Includes the number of times of key operation as keyboard operation data corresponding to the recognition data “A” in the information stored in the keyboard operation code creation information storage unit 7,
The pointers for the operation of the "katakana" key and the operation of the "3" key are sent to the keyboard signal generation unit 8.

In the keyboard signal creation unit 8, the keyboard signal when the "Katakana" key is pressed, the keyboard signal when the "Katakana" key is released, and "" in the information stored in the keyboard signal creation information storage unit 9 by the pointer. The keyboard signal when the 3'key is pressed and the keyboard signal when the '3' key is released are output to the keyboard signal output unit 10.

Next, the case of inputting the Chinese character "A" will be described. When the character input unit 4 reads the Chinese character “A” written on the sheet and sends it to the character recognition unit 5, the character recognition unit 5 recognizes the Chinese character “A” and recognizes the keyboard operation creation information data “A”. The pointer pointing to is sent to the keyboard operation code creation unit 6.

Then, the keyboard operation code creation unit 6 also includes the number of times of key operation as keyboard operation data corresponding to the recognition data "A" in the information stored in the keyboard operation code creation information storage unit 7. so,
The pointer of the key operation of "code input start", the operation of "3" key, the operation of "0" key, the operation of "2" key, the operation of "1" key and the key operation of "end of code input" are keyboard signals. Send to the creating unit 8.

In the keyboard signal creation unit 8, the keyboard signal when the "code input start" key is pressed in the information stored in the keyboard signal creation information storage unit 9 by the pointer and when the "code input start" key is released 'Keyboard signal,' 3 'key pressed keyboard signal and' 3 'key released keyboard signal,' 0 'key pressed keyboard signal and' 0 'key released keyboard signal,' 2 Keyboard signal when pressing the 'key and' 2 '
Keyboard signal when the key is released, the keyboard signal when the '1' key is pressed and the keyboard signal when the '1' key is released, the keyboard signal when the'code input end 'key is pressed and the'code input end' key The keyboard signal for opening is output to the keyboard signal output unit 10.

In this way, information such as characters input by means other than key input is output to the system unit as a keyboard signal as if the key input was made from the keyboard. Further, as shown in FIG. 4, since an expansion table is added to the keyboard operation code creation table, and the keyboard operation data of Kanji is stored in the expansion table, Kanji input is also converted into a keyboard signal. It can be sent to the system unit 3 as if it was input by key operation from the keyboard.

Therefore, the system unit can process input information from other than the keyboard as the same data as the key operation input from the keyboard. In the above example, a general JIS code is used as the keyboard operation code corresponding to the input operation of the kanji to be input, but other codes may be used.

The effects of the input device of this embodiment will be listed below. First, as to the improvement of the man-machine interface, (1) it is not necessary to remember the key layout, so that the input becomes easy. (2) The skill of key operation becomes unnecessary. (3) Control information (eg, space, cursor movement, shift, etc.) corresponding to various control keys as well as characters by handwriting input without using an unfamiliar keyboard
It is possible to input full-width / half-width, double-width, line feed, page break, conversion, etc., and to directly input Chinese characters, improving operability.

(4) There is no risk of erroneous input unless the character or the like is input by mistake. (5) It is possible to easily perform a fixed input operation such as starting a business program that is used everyday, by reading a card on which a series of operation information is printed and starting the apparatus. (6) Even persons with disabilities can easily input characters and the like. (7) Kanji can be input efficiently.

With respect to the hardware, (8) Since all input information is input as keyboard signals from the keyboard I / F, there is an increase in the load of different recognition processing on the system device side depending on the input means. Absent. (9) It can be used as it is for most data processing devices using a general keyboard, and has versatility.

(10) The size can be easily reduced without lowering the operability. (11) When applied to a filing device, the amount of data can be small because a code, not an image, can be input during filing processing, and resources such as a memory in the system device can be effectively used.

Next, another example of the portion surrounded by broken lines in FIGS. 1 and 3 will be described with reference to FIG. FIG. 9 is a block diagram similar to FIG. 1 in this embodiment.

The keyboard operation code creation unit of this embodiment includes a recognized character type determination unit 30 'for determining the character type of a character OCR recognized by the character recognition unit 5, and a character type recording unit 36 for recording the character type. An input mode for inputting information such as recognized characters and a keyboard operation information creating section 37 for creating a corresponding keyboard operation code by dividing the information into kanji and non-kanji, and an input mode for recording the character type of a character output as a keyboard signal. The recording unit 38, the character type recording unit 36, and the input mode recording unit 38 are provided with an input mode management unit 39 that manages the change of the input mode depending on the character type recorded in each character type.

Then, the type of character recognized by the character recognition unit 5 by OCR, that is, whether the character is a half-width alphanumeric character, a half-width katakana character, a full-width alphanumeric character, full-width katakana, hiragana, special mark, kanji character, or the like is determined. When the judgment is made and the character type is recorded in the character type recording unit 36, a keyboard operation code corresponding to the information such as the character by Kanji or non-Kanji is created and output to the keyboard signal creation unit 8 via the input mode management unit 39. To do.

At this time, the input mode management unit 39 compares the character type recorded in the input mode recording unit 38 with the character type recorded in the character type recording unit 36, and when both character types are the same. , The keyboard operation code for changing the input mode (Hiragana key, Katakana key, etc.) is not sent to the keyboard signal creation unit 8 and only the keyboard operation code of the character is output, and the character type of the character type recording unit 36 is input mode recording unit. 38 to record. Further, when the character types of both are different, the information of the input mode is also output to the keyboard signal creation unit 8.

Therefore, when the character type of the information such as the input character is the same as the last output, the information indicating the input mode is not output, so that it is not necessary to output an extra keyboard signal to the system unit side. The efficiency of input can be improved.

Next, the second to fifth parts of the input device according to the present invention will be described.
The embodiments will be sequentially described, but the description of the same parts as those of the first embodiment will be omitted as much as possible. First,
A second embodiment of the input device according to the present invention will be described. The external appearance of the input device 1'of this embodiment is the same as that of the input device 1 shown in FIG. 2, but a registration unit 11 is added as shown in the block diagram of FIG.

FIG. 11 is a block diagram showing the functional configuration of the registration unit 11 together with the character input unit 4, the character recognition unit 5, and the keyboard operation code creation information storage unit 7. The registration unit 11 includes a keyboard operation code creation information output unit 12 and a keyboard operation code creation information table change unit 13, and performs processing related to new registration of various Chinese characters.

FIG. 12 is a flow chart showing the process of newly registering a Chinese character by the registration unit 11 of the second embodiment. When the character input unit 4 in FIG. 11 reads the newly registered Kanji registration data, it sends it to the keyboard operation code creation information output unit 12.

Keyboard operation code creation information output unit 12
Creates keyboard operation code creation information (consisting of recognition data and keyboard operation data) from the newly registered Kanji registration data and sends it to the keyboard operation code creation information table changing unit 13. Then, the keyboard operation code creation information table changing unit 13 expands the table in the keyboard operation code creation information storage unit 7, adds (registers) the keyboard operation code creation information of Kanji to the table, and ends the process.

In this way, if the keyboard operation codes of various Chinese characters can be registered in the keyboard operation code creation information storage unit 7, the user can create a keyboard signal of a desired Chinese character in the keyboard signal creation unit 8. It can be sent to the system unit 3 via the keyboard signal output unit 10.

Next, a third embodiment of the input device according to the present invention will be described. The functional configuration of the input device of this embodiment is substantially the same as that of the input device 1'of the second embodiment shown in FIG. 10, but as shown in the block diagram of FIG.
As a function of, a recognition data search unit 14 is added, and change registration can be performed in addition to the above-described new registration of Chinese characters.

FIG. 14 is a flow chart showing the process of changing the Kanji registration by the registration unit 11 of the third embodiment.
When the character input unit 4 of FIG. 13 reads the Kanji registration data, it sends it to the keyboard operation code creation information output unit 12. The keyboard operation code creation information output unit 12 sends keyboard operation code creation information (consisting of recognition data and keyboard operation data) corresponding to the Chinese character to the recognition data search unit 14.

The recognition data retrieval unit 14 retrieves the recognition data of the keyboard operation code creation table already registered in the keyboard operation code creation information storage unit 7,
It is determined whether or not there is data that matches the recognition data of the keyboard operation code creation information to be registered, which is sent from the keyboard operation code creation information output unit 12. A normal image recognition technique is used to judge whether or not the search for the recognition data matches.

As a result, if there is no matching data, the keyboard operation code creation information table changing unit 13 is sent the keyboard operation code creation information of the Chinese character, and the table of the keyboard operation code creation information storage unit 7 is expanded,
It is additionally registered and the process ends.

If there is matching data, the keyboard operation code creation information table changing unit 13 sends the keyboard operation code creation information of the Chinese character, and the keyboard operation code creation information table changing unit 13 sends the data of the Chinese character to the keyboard. The keyboard operation code creation table is changed (updated) by replacing it with a matching one in the table of the operation code creation information storage unit 7, and the process ends.

In this way, by searching whether or not the kanji to be registered has already been registered, not only the expansion of the keyboard operation code creation information table but also the update can be performed, so that the operator has already been registered. You can change the data of the kanji that you are using.

Next explained is the fourth embodiment of the input device according to the invention. The input device of this embodiment has substantially the same functional configuration as the input device 1'of the second embodiment shown in FIG. 10, but as shown in the block diagram of FIG. The warning generating unit 15 is added to the function of the third embodiment shown in FIG.
2 connects the warning lamp 20 and the buzzer 21 shown in FIG. 2 to control lighting and extinguishing of the warning lamp 20 and generation of a warning sound from the buzzer 21.

When a newly registered or changedly registered Chinese character overlaps with an already registered Chinese character, this input device operates the warning lamp 20 and the buzzer 21 to generate an alarm sound. Let me know.

FIG. 16 is a flow chart showing the processing at the time of new registration and change registration of Chinese characters by the registration unit 11 of the fourth embodiment. The recognition data search unit 14 in FIG.
When the Kanji registration data to be newly registered or changed is received from the character input unit 4, it is determined by searching whether it is already registered in the table of the keyboard operation code creation information storage unit 7.

As a result, if there is coincident data, an instruction is sent to the warning generation section 15 via the keyboard operation code creation information table changing section 13 to turn on the warning lamp 20 and generate a warning sound on the buzzer 21. Change the operation code creation information by replacing it with the one already registered.

On the other hand, if there is no matching data, the table of the keyboard operation code creation information storage unit 7 is expanded,
Newly register the keyboard operation code creation information for that kanji. At this time, it goes without saying that the warning generation unit 15 does not operate, the warning lamp 20 is turned off, and the buzzer 21 does not generate a warning sound.

In this way, if a warning is issued when a Chinese character is newly registered or changed and registered, the already registered Chinese character is changed without the operator noticing. It will not happen (the operator can know it even if it is automatically changed).

Next explained is the fifth embodiment of the input device according to the invention. The input device of this embodiment is shown in FIG.
As shown in the block diagram of FIG. 13, the registration mode management unit 16 is added to the function of the registration unit 11 of the third embodiment shown in FIG.
The registration mode management unit 16 stores and manages either the changeable mode or the unchangeable mode as the registration mode by the input from the registration mode key 19 shown in FIG.

When the newly registered or changed registered Kanji overlaps with the Kanji already registered in the keyboard operation code creation information storage unit 7, this input device executes or cancels the registration or change. Can be selected.

FIG. 18 is a flow chart showing the processing relating to the registration or change and the execution / stop selection by the registration unit of the fifth embodiment. The recognition data searching unit 14 of FIG. 17 searches and determines whether or not the Kanji registration data from the keyboard operation code creation information output unit 12 is already registered in the table of the keyboard operation code creation information storage unit 7. As a result, if there is no matching data, it is newly registered as it is.

On the other hand, when there is matching data, it is sent to the keyboard operation code creation information table changing unit 13, and the registration mode managing unit 16 refers to the registration mode currently managed. This registration mode is for kanji registration /
It can be set in advance before the change or set at the same time as the kanji registration data.

If the registration mode for the kanji is a modifiable mode, the registration mode management unit 16 informs the keyboard operation code creation information table modification unit 13 of it, whereby the keyboard operation code creation information table modification unit 13 operates the keyboard. Change the code creation information by replacing it with the one already registered.

If the registration mode is the unchangeable mode,
The registration mode management unit 16 informs the keyboard operation code creation information table changing unit 13 of this, and the keyboard operation code creation information table changing unit 13 ends the process without changing the keyboard operation code creation information.
In this way, when registering a Chinese character, if it overlaps with an already registered Chinese character, the operator can select whether to execute it or cancel it. If the new registration or the change registration described above can be performed with respect to the special mark or the like, more various information can be input to the system device like a keyboard.

[0089]

As described above, according to the input device of the present invention, the input information of the characters including print or handwritten Chinese characters by the OCR or tablet input device and various control information can be input from the keyboard. Since it can be input to the system unit as the same keyboard signal as the key operation input of, it can be directly connected to various data processing devices using a general keyboard and used, and the versatility and flexibility of input operation can be improved. As a result, the man-machine interface can be improved. Then, the efficiency of inputting Chinese characters and continuous input of the same character type can be significantly improved.
