Abstract

PURPOSE:To easily perform the edit of a document by setting first and second areas almost in parallel with an input/output plane, and performing the edit of the character displayed on the first area by performing command input to the second area in the neighorhood of the first area. CONSTITUTION:When input is performed from a coordinate input part 4, input coordinate information is supplied to an area recognizing means 11, and it is judged whether the information is included in a character input area 41 or in an edit input area 42 by applying a coordinate arithmetic operation. When it is judged that the input is performed to the character input area 41, the input information is handled as the character, and is supplied to a character recognizing means 12. When the character recognizing means 12 recognizes what an inputted character is, a storage means 14 holds recognized character information transiently, and next, the character information is stored in a RAM 3, and also, it is written on a VRAM 5, and is displayed on a display part 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document processing device, in particular, a display surface of a display means and an input surface of an input means form a substantially common surface, and a user interface is performed by this input/output surface. , relates to a document processing device that performs document processing.

[Prior Art] Conventionally, a keyboard has generally been used for input into a document processing device, and all functions necessary for document creation have been input using the keyboard.

With this input method, in addition to the keys necessary for character skills,
A huge number of keys are required, including keys to move the cursor and specify the position, keys to issue editing commands, etc., and as devices have become more sophisticated in recent years, the number of required manual means has also increased. ing.

On the other hand, since the keyboard area and number of keys are limited, you can use the shift key or control key sequence to
It is also possible to give the same key different functions by changing the operation mode.

In such a modal operation method, in which multiple functions are set to the same input method depending on the mode,
When operating a certain key, the user must always be very conscious of the mode setting, which determines whether the input information is entered manually as characters or as an editing command.On the other hand, for the above input methods, The conventional display method was basically a screen on which the text being created was displayed, and there was no special area for editing operations, or there was only one special area.In recent years, coordinates By using an input device as an input means and placing it over a display device, a device has been put into practical use that allows characters to be input by hand with an input pen, displayed in actual size, and inputted as if they were written on paper. The input characters are converted into character codes through character recognition processing, etc. With such devices, it is possible to manually write characters without performing key operations, so it is difficult to master the complex key operation system. [Problems to be Solved by the Invention] However, even in document processing devices that perform handwritten input via coordinate input as described above, modal operation methods still prevail, especially in input mode and editing. The modes are strictly differentiated, and the user must always be aware of the mode of the device when using the device.If you want to operate in a different mode, you must select a command or menu using the input vent. The object of the present invention is to solve the above problems, to create a document that allows editing operations to be performed without being aware of the operating mode of the device as much as possible, and that allows processing to be performed accurately in accordance with the operations. An object of the present invention is to provide a processing device. [Means for Solving the Problems] In order to solve the above problems, in the present invention, the display surface of the display means and the input surface of the input means substantially have a common surface,
In a document processing device that performs document processing using this input/output surface as a user interface, the first area displays at least a line of characters input by the input means or other predetermined input means; A second area provided substantially parallel to the area is defined on the input/output surface, and by manually inputting a predetermined command to the input means on the second area, the second area near the command input position is defined. A configuration is adopted in which character data displayed on the display means corresponding to area 1 is edited. [Operation] According to the above configuration, the first and second areas are set almost parallel to the input/output surface, and the characters displayed in the first area are manually commanded to the second area in the vicinity. It can be edited by [Examples] The present invention will be described in detail below based on examples shown in the drawings.

Figure 1 shows the schematic configuration of a document processing device that employs the present invention. In this embodiment, illustrations of output devices such as printers are omitted, and only portions related to the user interface are illustrated. In the figure, reference numeral 1 denotes a CPU that controls the entire apparatus, and performs processing as described later in FIG. 4 according to a control program stored in a ROM 2. Reference numeral 3 is an RA used as a work area for the control program and a buffer for input document data.
It is M. In this embodiment, a coordinate input section 4 and a display section 6 are used as user interface means.

The coordinate input unit 4 is a coordinate input unit that includes a transparent coordinate input board placed on the display surface of the display unit 6, and a ben 4b for instructing the coordinate point position to this coordinate input board. To detect the position of the electric lli! A known input method using induction or ultrasonic vibration shall be used. The display unit 6 is a display unit that displays a bit image, and is arranged to overlap the coordinate input surface 4a. Display section 6 is LC
It is composed of D, EL elements, CRT, etc. The display data of the display unit 6 is stored in the VRAM 5. The VRAM 5 stores bit images that correspond one-to-one to the coordinate points on the coordinate input surface 4a. Further, the VRAM 5 stores bit information of the input coordinate points from the coordinate input section 4, thereby displaying characters, figures, etc. input from the input bezel 4b.

Figure 2 shows the document processing functions executed by CPU 1 in blocks. The functions of this CPUI and the input/output by the coordinate input section 4 and display section 6 will be explained with reference to FIG.

The CPUI displays the display unit 6 based on the input from the coordinate input unit 4.
and performs the user interface. The input/output areas of the coordinate input area 4 and the display unit 6, which correspond one-to-one in actual size, are divided into a plurality of areas, which will be described later, as shown in FIG. Figure 3 shows the coordinate input section 4 and display section 6 overlapped.
Shows the status of the information input/output surface. When a handwritten input is performed on the coordinate input surface 4ae of the coordinate input unit 4 using the input ben 4b, this input character is input to the character recognition means 12 through the later-described detection process of the input area recognition 11 steps, and the character recognition process is performed. After that, it is converted into a character code, and this character code is puffed into the storage means 14. In order to display characters on the display section 6, the character codes in the storage means 14 are developed into font data by a character generator (not shown), converted into bitmap data, and then used in the VRA.
M5, and is displayed at a position corresponding to the character input area 4l on the display section 6. As shown in the figure, a plurality of character input areas 41 are secured on the coordinate input screen on the display unit 6, and an edit input area 42 is arranged between each character input area 41. As shown in the figure, the input/output by the coordinate input unit 4 and display unit 6 simulates character input using a normal writing instrument.
The editing input area 42 corresponds to the space between the lines on a medium such as paper. Character input area 41, edit input area 42
is identified by displaying a broken line 41a1 and a solid line 42a. In this embodiment, characters are input by inputting them into the character input area 41 with the input pen 4b, and by inputting them into the editing input area 42.
Various types of character editing can be performed by inputting to . The manual area recognition means 11 of the CPUI detects which of the character manual input area 41 and the edit input area 42 an input is being made.

When the input area recognition means 11 determines that there is a human input into the character input area 41, the coordinate information from the coordinate input section 4 is input to the character recognition means 12, and the character is recognized. Further, when the input area recognition means 11 determines that the input is to the edit input area 42, the coordinate information from the coordinate input section 4 is transferred to the edit command recognition means 13.
is input and recognized. For example, when inserting characters, in Figure 3, the characters ``The present invention relates to a document processing device used as a word processor, etc.'' are input, and the characters are inserted between ``sou'' and ``ni''. , use the input ben 4b to insert an insert command (inverted V-shape used in normal composition work) 43 at a position on the edit input area 42 corresponding to the desired character in the character input area 41 directly above it. Execute by inputting . In FIG. 3, reference numeral 44 is a different m-set command, which specifies the range of the character string "word processor." This command is the fourth command similar to insert command 43.
The process is performed in steps S6 to S9 in the figure. The specified range of characters (strings) can be deleted from the document, copied to another location, or moved using known editing techniques. The editing command recognition means 13 recognizes the editing command input into the editing input area 42 by recognition processing substantially equivalent to that of the character recognition means 12, and the corresponding editing processing is stored in the storage means 14 by the command execution means 15. Executed on character code strings. Next, the operation of the above configuration will be explained with reference to FIG. Figure 4 shows the CP shown in Figure 2.
FIG. 2 is a flowchart explaining the document processing procedure of U1. It is assumed that the procedure shown in FIG. 4 is stored in ROM2 or the like.

When human input is performed from the coordinate input unit 4 in step S1, the input coordinate information is given to the area recognition stage 11, and in step S2 it is determined whether it is included in the character input area 41 or the editing input area 42. Determined by coordinate calculation.

If it is determined in step S2 that there is an input in the character input area 41, the input information is treated as a character, and the character recognition means 1
given to 2.

When the character recognition unit 12 recognizes the manually written character in step S3, the storage means 14 temporarily stores the recognized character information in step S4, and then further stores the character in step S5. Information is stored in the RAM 3, written in the VRAM 5, and displayed on the display unit 6.

On the other hand, if it is determined in step S2 that there is an input in the edit input area 42, the input information is treated as an m-set command and is given to the edit command recognition means 13.

In step S6, when the editing command recognition means 13 recognizes what the manually input editing command is, step S7
In step S8, the storage means 14 temporarily stores the recognized editing command information, and in step S8, the editing command information is stored in the RAM.
3, and is also written to the VRAM 5 and displayed on the display section 6.

Then, in step S9, the command execution means 15 executes the command according to the editing command information recognized by the editing command recognition means 13. The above processing is executed every time human power is performed in step S1. As described above, according to this embodiment, it is possible to identify whether the input information is text or an editing command depending on whether the human input information is input into the character input area 41 or the editing input area 42, so that the user always All you have to do is input the characters or editing commands in the correct area, which reduces the mental burden and greatly improves the operability of special C editing operations. In particular, in the above embodiment, human power and wR collection can be used differently by selecting the line (character input area) and the margin of the question (!manpower area), similar to the editing work using paper and writing instruments. This has the advantage that there is no need to be aware of the mode, and there is no need for troublesome mode switching operations.

Further, according to the above embodiment, since the editing command for inputting the editing command is configured in a shape that is generally used for document proofing, the apparatus can be used as a document proofing device.

Therefore, the apparatus of the present embodiment can be easily operated without any practice required as long as normal document processing using paper and writing instruments can be performed.

In the above embodiment, the most basic arrangement of the character input area 41 and editing input area 42 on the coordinate input screen 4a and the display section 6 was shown, but the configuration of the input/output screen is not limited to the above embodiment. Instead, for example, a document paper format as shown in FIG. 5 may be used.

Here, the document is displayed vertically on the display section 6, and a broken line 41 separates a text area 41 and an editing area 42.
a and 42a are displayed as vertical ruled lines similar to those on the manuscript paper. As the editing commands, as shown by reference numerals 43 and 44, the same ones (insertion, range specification) as in the case of FIG. 3 can be used.

According to this configuration, since the same format as the original paper is used, it is possible to realize an operational feeling that is closer to normal document processing using paper and a writing instrument. In this way, by setting a specific format that is unique to various document processes, you can have a more realistic feeling of handling actual documents. It is also conceivable to change the display format of some documents by operating a switch or the like.

In the above, we considered inputting characters by hand and recognizing the characters, but inputting only with the keyboard, etc., and using the coordinate input section 4 and display section 6 only for inserting, deleting, and other editing operations. Good too. In this case, the above-mentioned character input area 41 is used only for displaying characters.

[Effects of the Invention] As is clear from the above, according to the present invention, the display surface of the display means and the input surface of the input means form a substantially common surface, and this input/output surface provides a user interface and performs document processing. In the document processing device, a first area for displaying at least a line of characters manually input by the human input means or other predetermined input means, and a second area provided substantially parallel to the first area are arranged in front. By inputting a predetermined command to the human input means on the second area on the input/output screen, characters are displayed on the display means corresponding to the first area near the command input position. Since the configuration uses data editing, the first and second areas are set up almost parallel to the input/output surface, and the characters displayed in the first area are sent as commands to the second area nearby. Editing can be performed by inputting information, and by selectively using the first and second areas arranged close to each other, the document has the excellent effect of being able to easily edit the document without being aware of the operating mode.
