Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a document creation apparatus having a plurality of devices for inputting positions necessary for creating and editing a document.

[Technical background of the invention and its problems]

Conventionally, in devices such as word processors for the purpose of creating and editing texts, cursor keys arranged on the keyboard are used as a means to indicate the parts to be proofread when correcting or deleting the text. It was common to use on the other hand,
In devices such as CAD for the purpose of creating and editing figures, devices such as light pens and mice are used to input the positions. These devices have been selected to suit their respective purposes.

In recent years, devices for creating and editing documents containing a mixture of text and graphics have become popular, but all of them have only one device for position input. That is, a method is used in which a figure is drawn by depressing a cursor key on the keyboard to specify a position, or a mouse is used to indicate a part of the text to be corrected. In the former, the degree of freedom in moving the cursor is too small, and in the latter, if a keyboard is used to input proofread text, it is difficult for experienced typists to use the keyboard as it requires the effort of switching hands from the keyboard to a mouse. In the end, this actually hinders the efficiency of writing. In this way, using a single position input device to indicate different objects, such as text and graphics, poses a major difficulty in operability.

Therefore, in a document creation/editing apparatus that includes a mixture of text and graphics, it is necessary to prepare position input devices for different purposes.

[Purpose of the invention]

An object of the present invention is to provide a document creation device that satisfies the above-mentioned needs.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment device. There are two input devices: a keyboard 1 and a mouse 2. The input monitoring unit 3 constantly checks the input boards of the keyboard 1 and the mouse 2, and
The presses of keys, movements of mouse 2, and presses of mouse buttons are monitored. When a press of a key on the keyboard 1 is detected, an identifier indicating that the input is from the keyboard and a code indicating the location of the pressed key are transferred to the input control unit 4. Also,
If Mouse 2 movement or Mouse 2 button press is detected, an identifier indicating that the input is from Mouse 2, a vector indicating the distance and direction moved, and a code indicating the location and number of times the mouse button was pressed. is transferred to the input control section 4.

The input control section 4 determines from the identifier of the data received from the input monitoring section 3 whether the data is obtained from the keyboard 1 or the mouse 2. If the received data is from the keyboard 1, the code indicating the location of the pressed key is converted into an internal code handled by the document processing unit 5, such as an ASCII code or a JIS code, using a code conversion table. The data is converted into a code or various control codes and transferred to the document processing section 5. Furthermore, if the received data is from the mouse 2, the input control unit 4 always internally retains the previous position coordinates of the mouse cursor, The vector values indicating the distance and direction are added and converted into absolute position coordinates, and this coordinate value is newly held internally and transferred to the cursor display section 6. The cursor display unit 6 displays a predetermined mouse cursor pattern at the screen position of the CRT display 8 corresponding to this coordinate value, so the user is instructed to follow the movement of the mouse 2 on the CRT display 8. The mouse cursor above 8 appears to move. In addition, the input control unit 4 determines that the received data is from the mouse 2 and that the data received from the mouse 2 is
When button press information, that is, the location and number of times the mouse button was pressed, is received, the coordinate transformation described above is performed and the coordinate values are transferred to the cursor display section 6, and the coordinate values and the mouse button 2 are transferred to the cursor display section 6. The button press information is transferred to the document processing unit 5 to prompt document input and editing processing.

The document processing section 5 is a section that inputs and edits text, figures, and images based on the character code information, position coordinate information, and various control information transferred from the input control section 4, and is composed of these elements. It internally maintains and manages the structure of the entire document. It also drives the cursor display section 6 and document display section 7 to cause the CRT display 8 to display a cursor and a document.
Assume that key information from the keyboard 1 is now received from the input control section 4. In this case, the document processing unit 5
performs processing on text information among internally managed document information. If this key information is character code information, this character code or a character code obtained by performing kana-kanji conversion processing on this character code is inserted at the character string insertion start position currently held by the document processing unit 5, and this The results are immediately displayed on the CRT display 8 via the document display section 7. Furthermore, if this key information is control information such as deletion or movement, editing is performed according to those instructions, and the results are displayed. If this key information is keyboard cursor movement direction information, the document management section 5 internally holds the previous keyboard cursor position and the character spacing of the character strings existing before, after, to the left, and to the right. The character position to which the keyboard cursor should be moved is calculated from the character modification information such as line spacing and character size, and the direction of movement of the keyboard cursor just entered (up, down, left, right), and this is displayed in the cursor display area. 6, the keyboard cursor is displayed on the CRT display 8. At this time, to distinguish the keyboard cursor from the previous mouse cursor,
A pattern different from this will be displayed. As a result, when the cursor key on the keyboard is pressed, the cursor appears to the user to move character by character, resulting in cursor movement suitable for correcting sentences.

On the other hand, assume that the document processing section 5 has now received coordinate value information and mouse button press information from the mouse 2 from the input control section 4. In this case, the document processing unit 5 processes graphic information and image information among the internally managed document information. The document processing unit 5 first checks whether the received coordinate value information points to an area for inputting figures or images and giving editing instructions. Naturally, the area on the CRT display 8 corresponding to this area is displayed as a graphic image command instruction area. If the current received data points within that area, the command is identified by referring to a predetermined command conversion table based on the position, type and number of times the mouse button was pressed. and retains this internally. As a result, an instruction to draw a straight line, for example, is given. Next, if the received coordinate value information points outside the graphic image command instruction area, it is interpreted that the command previously received at that position is to be executed, and that instruction is executed. For example, if an instruction to draw a straight line has been previously given, the currently instructed location will be interpreted as the starting point of the straight line and the corresponding action will be taken. Furthermore, if an instruction to delete a figure has been previously given, it is interpreted that the figure in the vicinity of the currently instructed location is to be deleted, and that action is taken. In this way, commands given with mouse 2 are interpreted as instructions for inputting or editing figures or images.Moreover, unlike a keyboard cursor, the mouse cursor can be moved freely on the screen dot by dot. 2 can be used as an input device suitable for editing figures and images.

In the above description, a mouse has been used as an example of a pointing device, but other devices such as a tablet or a joystick may also be used. Further, although two position input devices, a cursor key on a keyboard and a mouse, are connected, three or more position input devices may be connected.

〔Effect of the invention〕

According to the present invention, in a document creation device that handles a document containing a mixture of text and graphics, a pointing device suitable for the purpose can be used, such as a cursor key on a keyboard when inputting and editing text, and a mouse when inputting and editing graphics. When selecting an input device, the operator does not have to give input device selection instructions to the document creation device one by one, and as a result, the operator's input editing efficiency is improved.
