Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document creation device used as a word processor or the like.

Conventional general-purpose word processors allow you to specify formats such as the number of lines in a page, number of characters in a line, line spacing, and character spacing when creating a document, and also specify the paper size such as A4 or B5, and the top and left side when printing. Details such as the dimensions of the blank areas in the section are specified manually by key personnel.

Problems to be Solved by the Invention In the conventional word processors described above, formats, paper dimensions, etc. are specified in detail by manual input. Therefore,
Document creators must perform complicated calculations in order to print the created documents on paper of a predetermined size in the planned arrangement, and if the calculations are insufficient, there will be too much or too little printing space, resulting in problems. The problem is that trial and error must be repeated over and over again.

Particularly, when writing characters only in the blank spaces of a manuscript paper written in a predetermined format, a problem arises in that the user must go through trial and error many times, reducing work efficiency.

Means for Solving the Problems The document creation/output device of the present invention includes an optical reading section that reads a document containing characters, etc. and creates a binary pattern of brightness and darkness, and a binary pattern of brightness and darkness that is read from the document. A pattern memory that stores the above two-dimensional array while maintaining it, a document RAM that stores a document created based on the two-dimensional array while maintaining this two-dimensional array, and the pattern memory and document RAM described above.
and a display control unit that sequentially reads out the contents of the display unit at a predetermined period, synthesizes the content of the display unit, and supplies the content to the display unit.

Furthermore, this document creation/output device includes means for prohibiting the creation of a document in an area in the document RAM corresponding to the pattern existing area in the pattern memory, and By including a printing unit that prints out discretely according to a two-dimensional array within the document format, the document is configured to be able to print and output documents on paper in a predetermined format without repeating complicated calculations or trial and error.

Hereinafter, the operation of the present invention will be explained along with examples.

Embodiment FIG. 1 is a perspective view showing the appearance of a document creation/output device according to an embodiment of the present invention.

This document creation/output device includes a main body part 1, a keyboard 2, a CRT 3, a printer 4, and an image sugi medium 5.
It is equipped with

The main body part 1 is configured as shown in the block diagram of FIG. 2, and 11 is a CPU (central processing unit), 12 is a program ROM, 13 is a work RAM, and 14 is a dictionary RO.
M, 15 is document RAM, 16 is pattern memory, 17
is a CRT control device, and 18 is a character generator (
CG), 19 is a synthesizer, and 20 is a D/A converter.

Further, 21 to 23 are ink face parts for the image scanner 5, printer 4, and keyboard 2, respectively, and 24 is a lotus that interconnects each part in the main body part l.

Before starting to create a document, the user of this document creation/output device first places the document on which the created document is to be printed out on the document reading window of the image scanner 5, and then presses the keyboard to start reading. 2 to CPUI in main body part 1
Command I. Before and after this reading command, A4 and B5
The keychain 2 notifies the CPU 1 of the document size within the standard, which is displayed in the vertical and horizontal directions, and the document size which is out of the standard, which is displayed in the vertical and horizontal chairs, and is stored in the work RAM 13.

When activated by the CPU II via the interface section 21, the image scanner 5 converts the document on the original into a pattern consisting of an array of binary signals of "i" and "o" corresponding to the brightness of the document, CPU via section 21
Transfer to I 1. CPU1l is image scanner 5
The patterned data received from the printer via the interface unit 21 is stored in the pattern memory 16 while maintaining the two-dimensional arrangement on the original.

When the CPU II finishes storing the patterned data in the pattern memory 16, it initializes (all clears) the contents of the document RAM 15, and stores data on the document RAM 15 corresponding to the area on the pattern memory 16 where the patterned data exists. Writes a control bit that indicates that writing is prohibited in the area.

The CRT control device 17 increments the address of the built-in address counter and updates the pattern memory 16 and document RAM 17.
The contents of each are read out sequentially at a predetermined period. The document read out from the document RAM 15 and converted into a corresponding dot pattern by the gear rafter generator 18 is combined with the document on the original read out from the pattern memory 16 in the synthesizer 19, and then transferred to the D/A converter 20.
is displayed on the CRTa via.

Before inputting a document, as illustrated in FIG. 3, the document read by the image scanner 5 is displayed as is on the CRTa in a black and white dot pattern. In the figure, areas where documents exist are illustrated by hatched areas, and areas where documents do not exist are illustrated by blank areas.

The above-mentioned intended screen size of the original to be displayed on the CRTa is determined for the case of standard character spacing and line spacing. When a specific character spacing different from the above-mentioned standard spacing is specified from the keyboard 2, the CPU II
The number of characters in a line is calculated from the width of the manuscript paper held in the , and the width of the displayed manuscript is changed to match this. Similarly, when a specific printing interval is specified from the keyboard 2, the CPU 1 calculates the number of lines in a page from the vertical width of the manuscript paper stored in the work RAM 13, and adjusts the number of lines in the displayed manuscript to match this. Change the height.

After setting the character spacing and line spacing to desired values as described above, the user moves the cursor to the beginning of each blank area on the display screen and writes the document by pressing a character key. Even if the user mistakenly tries to write into the pattern existing area in the document, the write will end in failure because the write-prohibited control bit is set in the corresponding area in the document RAM 1S.

When the user finishes writing the document in each blank space,
The same document that was read by the image scanner 5 is set in the printer 4, and the keyboard 2 instructs the CPU II to start printing. CPU that received this start command
1 identifies the size of printing paper from the size of the document stored in the work RAM 13, and transfers the document already created in the document RAM 15 to the printer 4 via the interface section 22 to print it out. As a result, a document created by writing in each of the blank areas that exist discretely between the dot patterns read by the image scanner 5 is printed out discretely in the gaps between the printed documents on the original. be done.

The configuration above has been illustrated in which the size of the document to be read by the image scanner is input from the keyboard, but it is also possible to adopt a configuration in which the image scanner optically detects the periphery of the document and automatically notifies the CPU of the size. You can also do it.

In addition, we have shown an example of a configuration in which the character spacing and line spacing of the document to be created are specified and the number of characters in a line and the number of lines in a page are automatically calculated from these and the size of the document, but conversely, the number of characters in a line and the number of lines in a page are specified It may also be configured to automatically calculate and notify the character spacing and line spacing.

Furthermore, although a configuration in which the character spacing and line spacing are common throughout the page has been illustrated, a configuration may also be adopted in which different character spacing and line spacing, or the number of sentences in a line or the number of blank lines are specified for each blank area.

In addition, although we have illustrated a configuration in which a write-protection control focus is added to an area in the document RAM that overlaps with a pattern existing area in the pattern memory, instead of this, a control bit that prohibits movement of the cursor into this area may be added. May be added.

Effects of the Invention As explained in detail above, the document creation/output device of the present invention optically reads a document in advance and stores the pattern, prohibits the creation of a document that overlaps this pattern, and This configuration creates a document on the document RAM while superimposing and displaying the text and the document on the CRT, and then prints out the created document discretely according to the two-dimensional array in the document RAM, which eliminates the need for complicated calculations. The effect is that a document can be easily printed/outputted on a document in a predetermined format without repeating trial and error.
