FIG. 2 shows an embodiment of the present invention. In the figure, 1 is a display unit, 2 is a key input unit, 3 is a pen input unit, 4 is an external storage unit, 5 is a printing unit, 6 is a communication unit, 7 is a control unit, 8 is an input control unit, and 9 is a document. A processing control unit, 10 is an output control unit, 11
Is a document creation / editing section, 12 is a proof data entry / deletion section,
Reference numeral 13 denotes a print / communication / auxiliary function unit, reference numeral 14 denotes a document data storage unit, and reference numeral 15 denotes a calibration data storage unit, which has a configuration similar to that of a general personal computer or word processor.

At the center is a control unit 7 for controlling the entire system, which includes a general-purpose microcomputer or a dedicated LSI. The display unit 1 is composed of a display such as a CRT or a liquid crystal, and the key input unit 2 is composed of a keyboard.
The pen input unit 3 is realized by a light pen, a pressure-sensitive sheet, or an electronic pen using electromagnetic induction or the like.

The external storage unit 4 includes a magnetic disk, a magneto-optical disk, a flash memory, and the like, and the printing unit 5 includes a printer. The control section 7 has sections for controlling input / edit / storage of documents, entry / deletion / storage of proof data, printing / communication thereof, and the like, and these are realized by firmware or a dedicated LSI.

A memory (so-called VRAM) to which data to be displayed is written is connected to the display unit 1.
This VRAM may adopt a bitmap method of treating characters and graphics equally, or a method of treating characters and graphics by separate VRAMs and combining them at the time of display. In any case, the document data is displayed on the screen according to the font read from the character font ROM, and the calibration data is displayed on the screen as a line drawing graphic of the portion traced by the pen input unit 3.

[0011] The document data is input to the key input unit 2 and the pen input unit 3
Alternatively, the document data is input from the communication unit 6 and stored in the document data storage unit 14 as a character code + modification code (a code indicating an attribute such as the font and size of the corresponding character) and is displayed as a character on the display unit 1. . The calibration data is input from the pen input unit 3 and the communication unit 6 and stored in the calibration data storage unit 15 as graphic data of a line drawing, and is displayed on the display unit 1 as a graphic such as a line drawing. A pointer is provided between the document data and the proofreading data so that their positions can be known.

As a method of realizing the pointer, (1) an area for “pointer to proof data” is provided for each character in the document data. (2) An area for “pointer to document data” is provided in each piece of proof data. Such methods are conceivable.

When used in an actual proofreading scene, the proofreading data follows the movement of the character, and when the character on which the proofreading data is written is deleted, the proofreading data is also deleted. Is considered to be convenient. In order to satisfy such specifications, it is considered preferable to realize the pointer by the method (1). Therefore, an embodiment adopting the method (1) will be described here.

[Data Structure] Here, the document data is shown in FIG.
As shown in (1), it is assumed that it is composed of three sets of columns of (character code + modification code + “pointer to calibration data”). It is to be noted that the modification code and the “pointer to the calibration data” may be separated from the character codes and inserted between the character codes. Here, the character code and the modification code are the same as those of the conventional word processor. The character code is a numerical value representing each character in the document, and the modification code is a numerical value representing modification information such as “double size”. The “pointer to the calibration data” indicates the number of the calibration data among the calibration data stored in the calibration data storage unit 15 at the position of the character.

When the "pointer to calibration data" is 0, it means that calibration data is not written at the position of the character. Providing an area for this "pointer to proofing data" for each character would be extremely wasteful (the proofreading character is almost always a small part of the document data. I can imagine)
For each character, prepare only a "calibration flag" area that indicates whether a "pointer to proof data" is set or not. (A two-point array of a “pointer to a character on which a“ proofing flag ”is set” and a “pointer to calibration data”) may be stored. The above document data is stored in the document data storage unit 14, and is stored in the external storage unit 4 as needed.

As shown in FIG. 3, the calibration data is graphic data indicating what line drawing has been written on the corresponding character. In the present embodiment, the size of the graphic data of each calibration data is a rectangular area including the corresponding character. Each piece of proof data also has an area for a pointer ("pointer to document data") pointing to the corresponding character in the document data. This is because only the calibration data is transmitted and if only the calibration data is received,
It is used when setting a "pointer to proof data" corresponding to the character in the document data indicated by this pointer.

Since the "pointer to the document data" is only used at the time of transmitting the proof data, it is not included in the proof data and is temporarily stored only at the time of transmission ("pointer to the document data" and "the character It is also conceivable to create the data in the form of a pair of two pointers to the corresponding calibration data). The above calibration data is stored in the calibration data storage unit 15 and is stored in the external storage unit 4 as needed.

[Document input when there is no proof data] In normal document input, document data is stored in the same manner as a conventional word processor without touching the "pointer to proof data" at all (always 0). / Display / Edit.

[Communication of Document Data] When exchanging document data with another person, a character code + modification code string is transmitted / received through the communication unit 6 in the same manner as in a conventional word processor communication function.

[Proofing data input / deletion] When the person who proofreads the document data checks or corrects a part of interest with an electronic pen or the like while reading the document data, the contents (graphic data of the line drawing) are changed. The data is input from the pen input unit 3 and stored in the calibration data storage unit 15. Then, the number of the proof data written at that time is set in the “pointer to proof data” of the character in the document data displayed overlapping the proof data. When the calibration data is deleted, the corresponding character "Pointer to calibration data"
To 0.

This processing will be described with reference to the flowchart of FIG. In step 1, the coordinates of the electronic pen are obtained. At this time, if the electronic pen traces the screen on which the document data is displayed, processing for writing / erasing the calibration data is performed. Therefore, the processing shifts from step 2 to step 3, but the coordinates of the electronic pen are written. If it is on the menu of the mode setting, it sets the writing mode in step 14 and returns to step 1; If the coordinates of the electronic pen are on another operation menu, the operation is processed in step 16 and the process returns to step 1. If the coordinates of the electronic pen are none of the above, the process returns to step 1 without doing anything.

In step 3, from the coordinates of the pen, the number of the character C displayed in the location pointed to by the pen is obtained in the document data and is substituted into a variable P. In step 4, branch depending on whether the mode is writing or erasing. If the mode is the writing mode, go to step 5;
Go to

In step 5, if the calibration data corresponding to the character C already exists in the calibration data storage unit 15, the process goes to step 6, and the calibration data stored in the calibration data storage unit is replaced with the electronic data. The process returns to step 1 after being changed to represent the line drawing traced by the pen. If the calibration data corresponding to the character C does not yet exist in the calibration data storage unit 15, graphic data representing the line drawing just drawn with the electronic pen is stored in the calibration data storage unit as calibration data in step 7; To set the "pointer to calibration data" corresponding to the character C to the number of the calibration data that has just been stored, and then return to step 1.

If the mode is the erasing mode, the procedure goes to step 9; if the calibration data corresponding to the character C already exists in the calibration data storage section, the procedure goes to step 10; otherwise, the procedure returns to step 1 without doing anything. . Step 1
If the value is 0, the calibration data stored in the calibration data storage unit is changed to represent a line drawing in which the portion traced by the electronic pen is erased. If the line drawing still remains after the erasing operation, the process returns to the step 1. If the proof data corresponding to the character C is completely erased by the current operation, the proofreading is performed in the step 12. The data is deleted from the calibration data storage unit, the “pointer to calibration data” corresponding to the character C is set to 0, and the process returns to step 1.

Because a “pointer to proofreading data” is set for each character of the document data, when the proofreading data is deleted from the proofreading data storage unit 15, 1) the deleted proofreading data is deleted. A flag indicating that the calibration data has been performed is set, and there is no need to close the calibration data. 2) The proofreading data existing after the deleted proofreading data is filled beforehand, and the “pointer to proofreading data” in the document data is recalculated. It is necessary to perform such processing.

[Screen Display] When the screen is displayed, while the document data is displayed, if the "pointer to proof data" of the character to be displayed is set, the proof data is also displayed. This processing will be described with reference to the flowchart of FIG. First, in step 1, the position of the first character in the screen display in the document is substituted into a variable P (a variable indicating the number of the character in the document data).

Next, in step 2, it is checked whether a "pointer to calibration data" corresponding to the P-th character has been set. If it is set, in step 3, the line drawing of calibration data indicated by the "pointer to calibration data" and P
And go to step 5,
If not set, the P-th character is displayed in step 4 and then go to step 5. In step 5, 1 is added to the variable P. In step 6, it is checked whether or not all the characters in the screen display area have been displayed. If not, the process returns to step 2;

[Communication of Calibration Data] (Transmission) After the calibration is completed, only the calibration data can be transmitted. At this time, it is necessary to calculate a “pointer to document data” in the proofreading data before starting communication so that the receiving side can set a “pointer to proofreading data” in the document data. In this process, the document data is viewed from the beginning, and for the character for which the “pointer to proof data” is set, the “pointer to the document data” of the proof data is set to indicate the character. .

This processing will be described with reference to the flowchart of FIG. First, in step 1, a pointer P to the document data (a variable representing the character in the document data) is set to 1
Set to. Next, in step 2, the numerical value in the “pointer to calibration data” corresponding to the P-th character is substituted for the variable G. In step 3, it is checked whether G is 0 or not.
If it is, go to step 5 immediately. If it is not 0 (it means that the calibration data corresponding to the character exists), in step 4, the G-th calibration out of the calibration data stored in the calibration data storage unit 15 After setting the “pointer to document data” in the data to P, go to step 5.

In step 5, 1 is added to the variable P. In step 6, it is checked whether P is larger than the number of characters in the document data. If not larger, the process returns to step 2. If larger, "pointer to document data" in all the proofreading data has been set. In step 7, all the calibration data is transmitted one by one, and the processing ends.

[Communication of calibration data] (Reception) The receiving side of the calibration data points to the pointer in the document data based on the contents of the "pointer to the document data" in the received calibration data. Set the "pointer to calibration data" for the character that is

This processing will be described with reference to the flowchart of FIG. First, in step 1, a pointer G to the calibration data (a variable indicating the order of the calibration data among the calibration data stored in the calibration data storage unit 15) is set to 1. Next, in Step 2, one calibration data is received,
It is stored in the calibration data storage unit 15. In step 3, the content of “pointer to document data” in the received proofreading data is substituted for variable P, and in step 4, “pointer to proofreading data” corresponding to the Pth character in the document data is set to G. Set. In step 5, 1 is added to the variable G. Step 6
Then, it is checked whether or not the calibration data to be received still remains. If the calibration data remains, the process returns to step 2, and if not, the process ends.

[Editing of Document Data When Proofing Data Exists] Since a "pointer to proofing data" is set from each character in the document data, the proofing data is automatically inserted into each character when inserting characters. Will follow you. When a character for which a “pointer to proofreading data” is set is deleted, the proofreading data indicated by the pointer is deleted, and then the character is deleted. Erase data at the same time.

This processing will be described with reference to the flowchart of FIG. First, in step 1, an input is made from the key input unit 2 or the pen input unit 3. If the input is the insertion of a character, the process of inserting the character is performed in step 3 and then the process returns to step 1. If the input is not an instruction to insert or delete a character, the process proceeds to step 5, performs the specified processing, and returns to step 1. If the input is to delete a character, go to step 6 and check if the "pointer to proofreading data" corresponding to the character to be deleted is 0. If it is 0, go to step 8 immediately. After the calibration data indicated by the “pointer to calibration data” is deleted from the calibration data storage unit 15, the process proceeds to step 8. In step 8, the character is deleted, and the process returns to step 1.

[Regarding How to Display Calibration Data and Other Uses] Since the proof data is displayed while viewing the document data at the time of display, it is possible to make a difference between how the document data and the proof data are displayed. For example, it is possible to blink only the calibration data to make it easier to distinguish it from the document data, or to use a color display for the display unit 1 to color the calibration data to make the screen easier to see.

When the original document is corrected while looking at the proof data, the original document data + proof data can be viewed while viewing the contents of the "original document data + proof data" by a multi-screen display function as in a conventional word processor. By making corrections to the “document data obtained by copying the contents of the document data”, the work becomes easier.

Further, not only for proofreading of documents, but also for underlining or writing annotations on electronic publications with an electronic pen, and communication functions such as word processing for distributing registrars for lectures and the like. It can also be used for purposes such as underlining and annotating a regime on the screen of a word processor or the like when performed.

FIG. 9 shows how the screen and internal data change when the calibration / correction operation is actually performed in this embodiment. This figure shows a case where "x" is drawn on "na" and "/" is drawn on "sa" after "kasana" is input as document data. Thereafter, a case where “sa” is deleted and a case where “ni” is inserted between “sa” and “na” are also shown.

As described above, according to the present invention, proofreading of a document can be performed by handwriting on a document screen of a word processor. By enabling transmission of only proofreading data, it is no longer necessary to retransmit document data after proofreading. In addition, the proofreader can concentrate on entering only the proofreading data without changing the document at all,
The creation / correction of the document can be performed by the document creator himself / herself.

On a black-and-white display, the calibration data and the document data are displayed in the same color, and it is difficult to distinguish them. Therefore, it is easy to make a distinction by blinking only the calibration data or blinking only the document data. When the calibration data can be used, the calibration data is displayed in red or the like, so that the display screen can be easily viewed. When correcting a document based on proofreading data, the screen can be divided into a plurality of parts and the document can be corrected while viewing the original document data + proofing data.

Further, the present invention can be used not only for proofreading of documents but also for underlining, writing annotations and writing letters on an electronic publication, and distributing a regime such as a lecture by a word processor. It can also be used for purposes such as underlining, annotating, and writing a letter on a regimen when using the communication function.

In the conventional handwritten communication function, since all of the data is handwritten graphic data, there has been a problem that the communication amount becomes large and it becomes impossible to distinguish between the document and the graphic data. By superimposing and displaying "document data" and "handwritten data", the amount of communication can be reduced, and a storage method that can distinguish between the two can be adopted.
