Description

TECHNICAL FIELD The present invention relates to a document creation device, and more particularly to a document creation device that combines and outputs characters input from a keyboard and characters input from an image reading device.

Prior Art In a word processor, characters that are input from an image reading device such as a scanner without being input from a keyboard have unique characteristics that are not found in printed text, such as handwritten characters, and it is difficult to faithfully reproduce minute details. is desired.

Purpose An object of the present invention is to provide a text creation device that can faithfully input minute parts of an image read from an image reading device and output them together with images such as characters input from a keyboard.

Configuration In order to achieve the above object, in the present invention,
a first input means for converting characters, etc. into codes and inputting them; a first storage means for storing image information corresponding to the codes inputted from the first input means; and inputting characters, etc. as image information. a second input means for
a second storage means for storing image information input from the second input means; image information stored in the first storage means; and image information stored in the second storage means. , and control means for controlling the image information to be synthesized and output, such that the density of the image information stored in the second storage means is greater than the density of the image information stored in the first storage means. Configure.

According to this, the image information such as characters inputted by the second input means has a higher density than the image information of ready-made characters such as printed characters stored in the first storage means. It is stored in the storage means. Thus, the control means can combine and output the image information stored in the first storage means and the image information stored in the second storage means.

Therefore, the second input means inputs image information such as handwritten characters, stores it in the second storage means at high density, and combines this image information with the image information of the printed character in the first storage device. It is possible to obtain written documents that are a combination of printed and handwritten characters.

In general, the stroke information of printed characters is mechanically expressed, that is, expressed as a black pixel distribution pattern divided into dots, so that the characteristics are clearly expressed and the shape of the letters is well-arranged.
The relatively low-density pixel division makes it appear relatively clear and orderly, but in handwritten characters, features such as curves and slopes tend to appear, and in mechanical representation, such features tend to disappear, such as handwritten characters. Since the density of the pixel data is increased as described above, the characteristics of handwritten characters are sufficiently and smoothly reproduced.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

FIG. 2a shows an example configuration of a printer that can be used in the present invention. These printers are generally printers (1 to 17) that also serve as copying machines. In the printer's copy mode, the document is scanned by the HLA illumination light.
The reflected light of IP is the first mirror FNI, the second mirror
SMI, in-mirror lens IMI and third mirror
It is guided to the surface of the photoreceptor on drum 1 by TMI.
On the other hand, the photoreceptor of the drum 1 is connected to the main charger 2.
is uniformly charged, and is exposed to the guided light to form an electrostatic latent image. This electrostatic latent image is made visible by depositing charged toner supplied by the developing device 4. On the other hand, the copy paper is taken out from the cassette CAS1 or CAS2 by the paper feed roller PSR1 or PSR2.
The taken-out copy paper is sent to the transfer section by rotating the register roller 6 in synchronization with the position of the latent image (the edge of the document). In the transcription department,
The toner adhering to the latent image area is transferred onto the copy paper by the transfer charger 7, the copy paper is separated from the drum 1 by the separation roller 8, and the toner is adhered (fixed) onto the copy paper by the fixing heater HEP.
The copy paper is sent to the output tray COT.
On the other hand, the toner remaining on the drum 1 is neutralized by a static eliminating charger 5 and collected by a cleaning roller 10. 11 is a cleaning blade.

The document reading scanning system of the printer uses illumination lights HLA,
It consists of mirrors FMI and SMI, and a carriage that moves them in the direction of the solid arrow without changing the optical path length.

The printer shown in FIG. 2a further includes an OPT (optical fiber tube) 3, and this OFT 3
An image signal from the outside is recorded by providing an image signal from an image storage device such as a video tape recorder external to the device. Such operation control of copying and image signal recording is performed by the electrical equipment section 17. Note that 13 is a board, 12 is an OFT holder that moves forward and backward with respect to the drum 1 on the board 13, and KB is a keyboard.

It is composed of interfaces 18e ₁ to 18e ₃ and a microcomputer system 19. The microcomputer system 19 includes input boards 19a ₁ , 19a ₂ and a central processing unit (hereinafter referred to as
Abbreviated as CPU. ) 19b, a semiconductor read-only memory (hereinafter referred to as ROM) 19c, a semiconductor read/write memory (hereinafter referred to as RAM) 19d, and a clock pulse oscillator 19e.

A floppy disk recorder 20 is connected to this handwriting image reading device 18, and a floppy disk 20a is attached to this recorder 20. In the ROM 19c of the handwriting image reading device 18,
Erases in response to key operations on the operation keyboard 18c,
Program data that partially performs writing, and a program that sends an image signal for writing to the OFT activation circuit of the electrical component 17 in response to a print start signal from the electrical component 17 when a specific key is operated. Data is stored. Based on this program data, the handwriting image reading device 18 stores the writing start address (Y _A ) in the RAM 19d when the tip of the pen 18b hits any point A with the writing start address key pressed. Then, when the tip of the pen 18b hits any point B with the write end address key pressed, the write end address (Y _S )
is stored in RAM 19d. When the write start key is pressed, the electromagnetic induction tablet 18a
Writing to the floppy disk 20a is performed in synchronization with the scanning of the floppy disk 20a. floppy disk 20
Since this is writing in which the same recording frame is repeatedly written every time the entire surface (that is, one frame) of the electromagnetic induction tablet 18a is scanned, it is possible to write on the electromagnetic induction tablet 18a with the pen 18b while pressing the write start key. When characters are drawn on the surface, the image signal of the image drawn on the entire surface of the electromagnetic induction tablet 18a is written into the memory area of one frame of the floppy disk 20a. After connecting the handwriting image reading device 18 to the printer shown in FIG. 2a and pressing the read key on the handwriting image reading device 18, the document IP
When you place the floppy disk 20a on the document table of the printer (Fig. 2a) and press the print button, reading from the floppy disk 20a is started in synchronization with the start of copying by the planter, and this reading is performed at a speed synchronized with the optical scanning of the printer. It is carried out. At this time, handwriting image reading device 1
The CPU 19b of 8 sends a signal "0: black image recording" that turns off the OFT3 light emission up to the write start address (Y _A ).
However, between (Y _A ) and (Y _B ), a readout signal from the floppy disk 20a ("1": light emission, no recording; "0": extinction, black image recording) is output, After (Y _B ), a signal "0" is output that turns off the light emission of OFT3. The optical system (FNI~TMI) is the original
The IP optical image is projected onto the photoreceptor drum 1, but (Y _A )
In the range from (Y _B ) (indicated by diagonal lines in FIG. 2b), an electrostatic latent image of the image drawn on the electromagnetic induction tablet 18a is formed on the drum 1, during which time the optical system
Exposure by FMI to TMI is blocked by shutter 21.

The printer shown in FIG. 2c does not use the shutter 21. In this case, a half mirror 14, a lens 15, and a CCD element 16 are added, and the image of the original IP is read by the original image reading device made up of the half mirror 14, the lens 15, and the CCD element 16. For example, the handwritten document reading device 18 following this printer is connected to the second b.
Although the configuration is similar to that shown in the figure, the floppy disk recorder 20 has two heads and is installed with a memory area of one frame apart so that reading and writing can be performed simultaneously. The memory area of one head and one frame is used for reading and writing the image data of the original IP read by the original image reading device (14 to 16), and the memory area of another head and another frame is used for the electromagnetic induction tablet 18a. Used for reading and writing drawn images. In this case, when the print switch is closed after pressing the original image reading key, the image of the original IP is read by the CCD 16 and written to the first memory frame of the floppy disk 20, and the handwriting reading key is pressed. Later, when a character is drawn with the pen 18b, it is written into the second memory frame of the floppy disk 20.
After this, the write start address is set to C as shown in FIG. 2b.
(X _C , Y _C ), set the write end address to D (X _D , Y _D ) shown in Figure 2b, and press the print button while pressing the read key to start exposure using OFT3 exposure. be done. At this time, the lamp HLA
is not lit, and optical systems FMI to TMI are not driven for scanning. The read data of the first memory frame of the floppy disk 20 is up to the write start address C.
The data read from the second memory frame of the floppy disk 20 is applied to the light emission energizing circuit of the OFT 3, and in the area from the write start address C to the write end address D (hatched area C-D in FIG. 2b).
Provided to OFT3's light emission energizing circuit.

The printer 27 shown in FIG. 3 cuts recording paper rewound from a roll 24 with a cutter 23, forms an electrostatic latent image on the recording paper with a multi-stylus head 22, and develops the latent image with a developing device 4. , fixing device
It is configured to be fixed with HEP. In this example as well, when the handwriting image reading device 26 is connected, the image on the document is read by the CCD element 16 while the document is being fed. In this case, a control device 19 composed of a microcomputer reads the original IP and writes it to the recording device 20, reads the image of the electromagnetic induction tablet 18a, writes it to the storage device 20, and reads the image from the storage device 20. It controls the storage operation of the storage device 27, etc. It is also possible to import image data of a widely used text from the external storage device 25 and combine it with the original IP or handwritten image. The operation method may be the same as that of the handwriting image reading device shown in FIG. 2b described above, for example.

As shown in FIG. 4, the handwritten manuscript reading device
It can also be a CRT light pen 180. In this case, the original image is first read by the original image reading device 26 and stored in the storage device 20, and then
Give it to the CRT of the CRT light pen 180 and display it,
Similar to the handwriting image reading device shown in FIG. 2c, handwritten characters can be input using a light pen. Other operations may be performed in the same manner as in the handwriting image reading device shown in FIG. 2c.

In addition, if the screen density is satisfactory,
Instead of the CRT light pen 180, a light pen that utilizes other display means such as a plasma display, LED array, liquid crystal display, etc. may be used.

Several examples of printers and handwriting image reading devices that can be used in the present invention have been described above. Next, one embodiment of the present invention will be described.

FIG. 1a shows an embodiment of the invention. This embodiment is roughly a Kanji word processor. In FIG. 1a, character generator 30
is a ROM that stores one character image as 24 x 24 bit image data, and holds the image data of the required number of characters. Memory grip per character (24
×24) is assigned a character code, and this character code is used to read the read address (group).
is specified. In addition to operation keys, the input board 28 is provided with a large number of character designation keys, and by pressing a character designation key, a code representing that character is stored in the character code memory 29. The ROM 19c of the central control unit 190 stores program data for writing into the memory 29 and changing the contents of the memory, such as character code input, erasure, line change, pitch setting, correction, and addition. When you input the characters of the required sentence using the input board 28,
The character codes are stored in the memory 29 in the order of arrangement, and the text is displayed on the CRT display 33.
Changes in text or characters are made by operating keys on the input board 28 while looking at this display. When the print operation key is pressed, the storage device 270 stores the text and prints out a copy. Each of these elements and functional operations are already known in word processors. In contrast, according to the present invention, a handwriting character setting device 181 consisting of a handwriting image reading device 26, an input board 18c, and a handwriting character memory 31 is added, a frequency divider 34 is added to the central control device 190, and A handwritten character setting program and handwritten character recording program data, which will be described later, are added to the ROM 19c.

In the handwriting image reading device 26, the manuscript card
The size of the predetermined square on the IP-C is set to the character size represented by the 24 x 24 bit data written in the character generator 30, and the size is set to 48 x
The magnification of the optical system is determined so that the pixels are divided into 48 bits and read. This is because the handwritten characters are read by dividing them into finer pixels than the characters fixed in the character generator 30 in advance, and are recorded at a higher resolution so as not to lose the subtle features of the handwritten characters. be. The handwritten character image data (48 x 48 bits per character) successively read by the reading device 26 is stored at the address (handwritten character code) of the handwritten character memory 31 specified by the key operation on the input board 18c. be remembered. The handwritten character memory 31 is a RAM made nonvolatile by a battery backup circuit 32, and stores images by allocating 48×48 bits per character. 1 set of 48×48
Character code (address) assigned to bit
is a code that can be input by key operation on the input board 28, but is not assigned to be read by the character generator 30 (hereinafter referred to as an empty character code).

To explain the operator's operations in this embodiment, a brush, fountain pen, or magic pen is used to draw several or tens of squares for writing characters on a manuscript card in a color or density that cannot be read by the reading device 26. ，
Write the letters by hand using a felt-tip pen, pencil, etc. so that they fit within the squares. Then, among the free character codes, determine which ones will be assigned to handwritten characters,
Identify it by key operation. and manuscript card
Set the IP-C in the reading device 26 and read the image. In this image reading, the image data of each character is input into the handwritten character memory 31 in the order of the character code input by key operation. The character code (character key) assigned to each character is written on the original card IP-C, and the original card IP-C is placed near the input board 28.

When creating text, input is done by key operation as in the case of a normal word processor, but in the case of handwritten characters, the keys assigned to the handwritten characters are input by referring to the manuscript card IP-C. (or key operation order: character code). After that,
All you have to do is look at the display on the CRT display 33, make any necessary changes or corrections, that is, edit, and issue a printout command.

When displaying on the CRT 33 and when printing out, the central control unit 31 monitors the read character codes from the character code memory 29 based on the program data stored in the ROM 19c, and reads empty character codes. , the operation control clock pulse is switched to one with twice the frequency, and the fixed character code (character generator 3
The pixel data specified by the fixed character code is read out twice from the character generator 30 by reading out the same pixel bits in both the vertical and horizontal columns until only the character code specified for reading 0 is read out. read out. As a result, while characters with free character codes are recorded as 48 x 48 dots in the same area, characters with fixed character codes are always recorded as 24 x 24 dots (actually, in the handwritten character recording line, 48 x 48 dots are recorded). This results in 48 dots, but since only 1 bit of pixel data is assigned to 4 adjacent pixels in the read character from the character generator,
24 x 24 dots).

The purpose of making handwritten characters as detailed as 48 x 48 dots is to record handwritten characters at a higher resolution and accurately capture the emotion of the handwritten characters. Roughly speaking, if a character is represented by 24 x 24 dots as shown in Figure 1b,
The size of each part of the character is not accurately expressed, resulting in a mechanical character, but if it is set to 48 x 48 dots, it will be similar to the one shown in Figure 1c, and a smooth emotion will appear.

Generally, in a kanji word processor, the number of characters that can be stored in the character generator 30 is limited, and there may be a shortage of characters. At that time, the required characters are read into the RAM 31 by the reading device 26.
By writing the missing characters into the text, you can record the missing characters as part of the other characters in the text. Also, company marks and special symbols can be added to the memory RAM 3.
It can be stored in 1. Since the handwritten character memory 31 is nonvolatile, once written, it can be used many times thereafter.

Although only one embodiment has been described above, the printer 2
Of course, a normal dot printer or a laser printer can be used as the printer 70, or the printer shown in FIG. 2a, FIG. 2c, or FIG. 3 may be used. In addition, as the handwriting image reading device 181, FIG.
The one shown in FIG. 3 or FIG. 4 may also be used.

Effects According to the present invention, it is possible to obtain a document that is a combination of image information specified by a code such as characters input from a keyboard and image information such as characters input from an image reading device. Furthermore, since the image information input from the image reading device is configured with a high density, even minute details are faithfully reproduced.
