Description

TECHNICAL FIELD The present invention relates to an output character spacing automatic adjustment device mainly used in a character processing device such as a word processor.

(B) Prior Art Conventionally, in a character processing device such as a word processor, each character to be printed is, as shown in FIG. 5, a font represented by horizontal size m dots and vertical size n dots (hereinafter referred to as a font). A letter frame (hereinafter referred to as "body face") including horizontal size M dots and vertical size N dots including a "letter face") and an edge margin area added to the font.
Therefore, when the specified character spacing is X dots and the line spacing is Y dots, the character spacing J when actually printed is J = X + (M−m) Dot Also, the line interval I when actually printed is the interval represented by I = Y + (N−n) dots.

(C) Problems to be Solved by the Invention Therefore, in the above-mentioned cases, when the body face and the letter face are very close to each other, it is possible to print at the substantially specified character spacing and line spacing. However, as the difference between body face and letter face widens,
Character spacing and line spacing when printed were gradually different from those specified by the user.

The present invention has been made in consideration of such circumstances, and corrects character spacing at the character spacing specified by the user by correcting the character spacing to a value considering the difference between the body face and the letter face when outputting characters. The present invention provides an automatic output character spacing adjustment device for outputting characters.

(D) Means for Solving the Problems FIG. 1 is a block diagram showing the configuration of the present invention.

As shown in this figure, according to the present invention, an input unit 101 for inputting a character and a character interval, an output unit 102 for visually outputting a character, and a first memory for storing character information input from the input unit 101 are provided. Means 103 and second storage means 10 for storing the character pattern, and the frame (body face) size and letter face (letter face) size of the character pattern.
4, third storage means 105 for storing the character spacing input from the input means 101, and character spacing corrected by subtracting the difference between the frame size and the font size from the character spacing stored in the third storage means 105. Correction means 106, and the first
The characters stored in the storage means 103 are stored in the second storage means 1
Output means 102 based on the character pattern stored in 04 and the character spacing corrected by the correction means 106.
The output character spacing automatic adjusting device is provided with an output control means 107 for controlling the output.

(E) Operation According to the present invention, when the character information stored in the first storage unit 103 is output from the output information 102, the correction unit 106 determines the frame size from the character interval stored in the third storage unit 105. The difference between the character size and the font size is subtracted to correct the character spacing.

Then, the output control means 107 causes the output means 102 to output the characters stored in the first storage means 103 based on the character pattern stored in the second storage means 104 and the character spacing corrected by the correction means 106. Control. As a result, the characters stored in the first storage unit 103 are output from the output unit 102.

Therefore, since the character spacing is corrected, the character spacing will not be output widely due to the difference in size between the frame (body face) and the font (letter face).
It becomes possible to output the characters stored in the third storage unit 105 at accurate character intervals.

(F) Embodiment Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. The present invention is not limited to this.

FIG. 2 is a block diagram showing the configuration of an embodiment in which the present invention is applied to a word processor.

In this figure, reference numeral 1 is a keyboard as an input means equipped with a kana key and a function key, for inputting character information such as characters, numbers and symbols, and for instructing printing. Reference numeral 2 is a display unit including a CRT display or a liquid crystal display for displaying character information input from the keyboard 1 and various processing contents, and 3 is a display unit 2
Is a display control unit for controlling the display of 5 and 5 is a microprocessor, and 6 is a printer for printing character information.

7 is a RAM (random read / write memory), 8 is a ROM
(Read-only memory) 9 is a disk device.

In the disk device 9, as shown in FIG. 3, character forms for printing characters input from the keyboard 1, that is, information as a character generator for forming various character patterns P is created and stored in advance. ing. In addition, the vertical and horizontal sizes of the letter face LF and the vertical and horizontal sizes of the body face BF in the character pattern P are also stored. In this embodiment, the letter face LF has a size of 28 × 28 dots and a body size. The face BF stores each size of 32 × 32 dots. It should be noted that this disk device 9 can store a plurality of types of character generator information. In addition, the character generator information and the size of the character pattern are the same as those of the floppy disk or the R
It is also possible to store it in another storage medium such as OM.

Reference numeral 10 is a character information area secured in the RAM 7 for storing character information input from the keyboard 1, and 11 is a print dot buffer also secured in the RAM 7, and character and character when character information is printed. The interval X, that is, the inter-character dot X, and the line interval, that is, the line feed pitch Y are stored in dots. The print dot buffer 11 stores the inter-character dots and the line feed pitch specified by the user from the keyboard 1. However, if the user does not specify these, the standard inter-character dots are set by the microprocessor 5. And the line feed pitch is memorized.

Reference numeral 12 is a print image buffer formed by the microprocessor 5 for temporarily storing a print image to be actually printed.

A correction program 14 is stored in advance in the ROM 8 and corrects the inter-character dot X and the line feed pitch Y stored in the print dot buffer 11. This correction is
First, the difference x between the lateral size M of the body face BF and the lateral size m of the letter face LF stored in the disk device 9, and the difference y between the vertical size N of the body face BF and the vertical size n of the letter face LF. Is calculated as x = My−Ny = N−n, and then these differences x and y are subtracted from the inter-character dot X and the line feed pitch Y stored in the print dot buffer 11 to obtain the correction. The correction is performed by obtaining the inter-character dot I = X−x and the corrected line feed pitch J = Y−y.

Reference numeral 15 denotes a print control program stored in the ROM 8, which reads character information from the character information area 10, reads a character pattern corresponding to each of these characters from the character generator of the disk device 9, and further uses the correction program 14 to read the character pattern. An actual print image is developed in the print image buffer 12 based on the corrected inter-character dot I and the corrected line feed pitch J.

The print image is output to the printer 6, and the printer 6 that receives the print image prints character information.

In such a structure, the operation of this embodiment will be described below with reference to the flowchart shown in FIG.

Here, it is assumed that the character information input from the keyboard 1 is already stored in the character information area 10, and the print dot buffer 11 has a value of 4 bits as the inter-character dot X and a value of 20 dots as the line feed pitch Y. Is stored.

First, when printing is instructed from the keyboard 1 and the correction program 14 is loaded into the microprocessor 5, the microprocessor 5 reads the body face BF and the letter face LF from the disk device 9 and sets the lateral size M of the body face BF. The difference from the lateral size m of the letter face LF 4 = 32-28 (x = M-m) dots is calculated (step 201), and the body face BF is also calculated.
The difference between the vertical size N and the vertical size n of the letter face LF 4 = 32-28 (y = N-n) dots is calculated (step 202).

Then, the above-mentioned difference in horizontal size is subtracted from the inter-character dot X stored in the print dot buffer 11 to calculate a corrected inter-character dot I 0 = 4-4 (I = X−x) dot (step 203). Further, the corrected line feed pitch J 16 = 20−4 (J = Y−y) dots is calculated by subtracting the above vertical size difference from the line feed pitch Y (step 205).

Next, when the print control program 15 is loaded, the microprocessor 5 reads the character information from the character information area 10 and reads the character pattern corresponding to each character from the character generator of the disk device 9,
Furthermore, based on the corrected inter-character dot I and the corrected line feed pitch J obtained by the correction program 14, that is, the inter-character dot is 0 dot and the line feed pitch is 16 dots,
The actual print image is expanded in the print image buffer 12.

Then, this print image is output to the printer 6,
Receiving this, the printer 6 prints character information (step 205).

Therefore, in the conventional case, the character interval was 8 bits (4 + 4 = 8) and the line interval was 24 dots (20 + 4 = 24). However, by performing the above correction, the character interval becomes 4 bits ( 0 + 4 = 4) The line spacing is 20 dots (16 + 4 = 20), and the characters are accurately printed with the inter-character dots stored in the print dot buffer 11 and the line feed pitch.

If the dots between characters and the line feed pitch are corrected in this way before printing, the character spacing and line spacing actually printed will differ depending on the size of the body face and letter face. It will not be printed wider than the space dot and line feed pitch, and it will be possible to print accurately at the specified inter-character dot and line feed pitch.

It should be noted that, in the present embodiment, it is described that the character generator information stored in the disk device is one type, but for example, if the disk device stores a character generator for printing at 40 × 40 dots. In this case, if characters of 40 × 40 dots for body face and 32 × 32 dots for letter face are prepared and stored in the disk device, 32 × 32 characters can be easily written without changing software such as a print control program. It is possible to print with dots. That is, by storing different types of character generator information in the disk device in this way, if the size of the body face is less than or equal to the size of the body face, it is possible to easily print in any character size without changing the software, that is, It becomes possible to perform multipoint printing.

(G) Effect of the Invention According to the present invention, the character spacing is corrected so that the characters are output. Therefore, the character spacing is wider than the designated one due to the size difference between the body face and the letter face. It will not be output, and it will be possible to output characters accurately at the specified character spacing. In addition, it is possible to easily output a character with an arbitrary letter face size equal to or smaller than the body face size by using a plurality of predetermined fonts of different types.
