The present invention relates to a method for generating a character for a computer system and an apparatus thereof, and in particular, to process a character as a figure, to enlarge or reduce a predetermined typeface or shape, to make the outline of a stroke thin or thick, or to increase or decrease a character. The present invention relates to a method and apparatus for generating a character capable of changing the format of a predetermined character, such as increasing or decreasing in a direction.

Conventional personal computers display Chinese characters in a dot matrix manner. In this way the character is limited and the size of a character represented by the dot matrix, depending on the storage capacity in the memory, which can be calculated by the formula n ^2/8.

For example, n = 16 points to 32 bytes per character and n = 24 points to 72 bytes per character. The two sizes illustrated above (16 × 16) and (24 × 24) are the size of the dot matrix of the most widely used characters at present. In order to be able to extend or deform characters, the occupied memory capacity must be enormously enlarged. Also, the outline of the letters is serrated, so they are not flexible and the appearance time is long. The range of change is extremely limited.

Due to these problems, there have been many difficulties in enlarging or transforming characters in a personal computer. In addition, in the case of typewriters, typography, word processors, etc., if you want to process such low-resolution characters in the same system as high-resolution graphics, the software must be supplemented or replaced.

Therefore, the conventional method is limited in the character storage capacity of a computer, lacks the variability of Chinese characters and the like, and has no general purpose, and thus has not been applied to the trend of modern information processing aiming for a quick and inexpensive one.

With this in mind, the present invention can process characters in the same high resolution as a figure in a computer system, and can designate a letter including a font as well as freely enlarge, reduce or thinner. It aims to enable deformation by increasing or decreasing in the vertical direction.

In addition, the present invention does not need to enlarge the memory capacity of each character to be able to modify the character, it is an object to be applicable to the memory capacity of the conventional system.

In order to achieve the above object, the character generation method for a computer system of the present invention is to give a shape method, a stroke symbol based on a stroke shape that varies depending on the shape of each character and each type, such as Chinese characters, for each stroke element constituting the character. Steps to make the canvas and store it in the memory of the canvas and, for example, the kanji in the above characters, the number of copies or a group such as a piece, a room, a tube, a corner, etc. It can be decomposed into other constituents such as (單體), and each resource with a high frequency of occurrence is used as a resource, and a resource table is assigned to each shape and symbol of each resource according to the above table. A step of storing the resource table in the resource group memory, i.e., a resource group for each character, which assigns an address to each expert (regardless of the character) and constitutes each character according to the resource table. And assigning the stroke symbol to the stroke group which does not constitute a resource, and makes a character table for each stroke group for each resource group of each character, and stores each character in the substitute address in the character table memory. And assigning identifiers to auxiliary variables for the selection of characters, storing them in the auxiliary variable memory, creating codes corresponding to each character, and storing them in the code memory, and for each stroke. A step of producing a program for calculating the corresponding contour dot coordinates 22 and writing them to the stroke calculating device 16; inputs a character signal for character selection and auxiliary variables for character shaping selection; Is input via the code memory, and the corresponding character code is called to input the character table memory, and A surrogate resource group or stroke group is called from the system and inputted to the stroke calculating device at the same time as the auxiliary variable input, and the stroke calculating device substitutes the stroke symbols of the respective strokes of the respective characters in the resource table memory and the stroke memory. A character calculation program is called, whereby the dot coordinates of the respective strokes are calculated and outputted, and upon receiving this output signal, the video signal generator generates corresponding vector signals and outputs the corresponding vector signals to predetermined characters of each corresponding character. It is characterized by switching to a shaped signal.

According to the type of the letter type or the linear nature of the letter body, for example, it is not possible to clearly distinguish stroke elements such as Chinese characters, Japanese or Kana, phonetic characters, or predetermined symbols or figures. Collect them separately to make special codes, and designate special code tables by designating symbols for each special code, and these special code tables are called by the above program to calculate and output the dot coordinates of the special codes. It is also characterized by being stored in the code memory and expanding the computer system character processing capability.

In addition, the shape signal here refers to a character or special code constructed through a high resolution drawing device or a dot matrix signal converted to a dot matrix signal so as to fill the dot within the outline of the character or special code via a dot matrix computing device. The dot matrix signal is a high-resolution out foot device, such as a video tube or a recorder.

According to the method and the apparatus, only a character signal for character selection and an auxiliary variable for character molding selection are inputted, and a character or a figure stored in the memory is inputted by a code of a code memory or a special code memory by a computer. The internal operation from the symbol to the vector signal generation can be converted into a shape signal by arbitrarily expanding, increasing or decreasing in the vertical direction.

EXAMPLE

Hereinafter, the present invention will be described through examples.

First, it demonstrates with the following table, referring FIG.

3 to 22 show the kanji characterization bodies according to the embodiment of the present invention. In addition to the characterization body, three bodies, three black bodies, three bodies, and illuminations are shown. Sieve body, black body, trillion body, haeju, chesape, etc. likewise decompose stroke composition and give stroke symbols for each stroke element. By this, we can produce stroke with sign for every shape.

For example, the symbol of the carrier is zero (see description of identifiers below). There are 79 types of stroke symbols of the stroke elements from 0 to 78. The symbols A-A 'and B-B' appear in each of the strokes in the table, and are reference points of the thickness and the vertical length of each stroke as key points.

This and the stroke forward point are important auxiliary variables of the program for calculating the coordinates of each dot of the contour corresponding to the following stroke. The stroke mark is stored in the stroke mark memory 17 (see FIG. 1).

23 to 32 are examples of the resource table of the Chinese character carrier as one embodiment of the present invention. The Chinese characters are broken down into strokes and can be all stroke elements. Alternatively, since there are parts of a rectangular tube with a relatively high frequency of use, it is possible to produce resource tables for each shape by defining them as resources and classifying them in the order of stroke.

As illustrated, the symbol for each resource is assigned to each resource table, and the symbol for each resource is assigned to each resource. Although omitted in the illustrated table, as described above, polar resources are decomposed again by the stroke table, and stroke symbols are given for each stroke. The resource table is stored in the memory 21 (see FIG. 1).

Shown in FIG. 33 is the shape table of the Example of this invention. This table gives address to each kanji in spite of any character except the following special symbols, whether it is a song, three or three, hieroglyphic or chess, and according to the resource table, each resource contained in the composition of the character A resource group with the stroke-specific symbol for each resource is produced, and a stroke group with the stroke-specific symbol is produced by attaching a classification symbol to the rest of the other components based on the number of strokes. The magnetic table is stored in the magnetic table memory 12 (see FIG. 1).

As shown in FIG. 39, when the stroke element cannot be clearly identified, for example, a Chinese character, a Japanese letter "Kana", a phonetic alphabet, or a special character "★…" and a figure are special. A symbol is given as a sign and an auxiliary variable of a program for calculating the coordinates 22 of each dot of the contour corresponding to the corresponding code below as shown in the above-described stroke method, indicating key points of such thickness, key points of vertical length, and the like. A special sign table is produced as shown.

This special code table is stored in the special code table memory 31 (see FIG. 1). An identification symbol is assigned to the auxiliary variable 15 for selecting the modeling of the characters, and stored in the auxiliary variable memory 15 (see FIG. 1). As an example, 0 to 240 may be specified as the stroke identifier, but only 0 to 78 is used for the carrier. The identifier of the resource can be set to 254 or more, but can be freely expanded and increased because there is no upper limit.

For example, the symbol for each resource of "之" is 18 (see FIGS. 23 to 32), but the transmission signal is (254 + 18 = 272). In addition, as an auxiliary variable of a program for calculating the dot coordinates below, the stroke calculation device 16 (FIG. 1), which is further divided into the followings, is described later through the auxiliary variable memory 15 (see FIG. 1), respectively. You can select the typeface or format of the text.

(A) the length of the letter (according to the title indicating the size of the letter)

The length of the text indicates the length of the text in the vertical direction, and is limited to 16 to 1024 dots. That is, the dot matrix (16x16) to (1024x1024) range. When trying to select the length of a character, first, for example, 241 must be entered as an identifier.

(B) Types of shapes

In order to distinguish the typeface or type of Chinese characters, 0: Songjo, 1: Signature (light slender and long font on dark background), 2: Blackish body (dark and slender font on light background), 3: Three font (thin and thin curve) Long typeface), 4: illumination body (bright wide typeface), 5: rough black body (dark wide typeface), 6: trigonometric type (width typeface of curved line), 7: haeseo (8 書), 8: Symbols such as Chess can be given from 0 to 256. When trying to specify a kanji type, first, for example, 242 must be entered as an identifying symbol.

(C) Stroke thickness (width)

An auxiliary variable of the stroke thickness indicates a multiple of the reference thickness (A-A ') of the strokes listed in the stroke table, and is limited to a value of zero or more. If you want to specify the thickness of the stroke, you must first enter, for example, 243 as an identifier.

(D) Auxiliary variables for the ratio of the length (length) to the width (width) of a character are expressed in multiples of the length of the character and are limited to zero or more, and the identifier is designated as 244, for example.

(E) Special code

As a special code, for example

Each symbol may be given. The identifying symbol is designated as 245 as an example.

Next, a code that is substituted for each character is designated like a normal code set, a code table is produced, and stored in the code memory 11 (see FIG. 1). Next, a program for calculating the coordinates 22 of each dot of the contour corresponding to each special symbol for each stroke is produced, and the program is stored in the stroke calculating device 16 (see FIG. 1).

As described above, the embodiment of the present invention includes a code memory 11, a shape table memory 12, an auxiliary variable memory 15, a stroke number training device 16, a resource table memory 21, a table memory 17 and a special code memory. We use (31).

As shown in Fig. 1, this embodiment of the present invention again uses a video signal generator 23, a high resolution drawing device 25, a dot matrix computing device 27, and a high resolution out foot device 28.

As shown in FIG. 1, when the above-mentioned memory, apparatus and the like are combined as described later, the present embodiment is the shape generator 1 shown in FIG.

Next, with reference to FIG. 1, the operation and configuration relationship of the present embodiment will be described. As shown in FIG. 1, when a character signal for character selection and an auxiliary variable 15 for character shaping input are input, the character input 10 passes from the code memory 11 via the code memory 11. The code of the corresponding character is called to be put in the character table memory 12, and the resource group or stroke group is called from the address corresponding to the character in the character table memory 12 to input the auxiliary variable (15). The corresponding characters stored in the resource table memory 21, the stroke table memory 17, and the special code memory 31 by the stroke calculating device 16 at the same time. Invoke the program of the character or the special symbol based on the stroke symbol or the special symbol asterisk of the special symbol, and calculate the coordinates 22 of each dot corresponding to the character or the symbol by the program. Input to the signal generator 23, input to the video signal generator 23, generate the vector signal 24 by the video signal generator 23, and again generate such a vector signal 24; Is converted into a letter-shaped signal, i.e., characters 26 and 26 'or special symbols 26 "and 26"'.

In the case where the stroke structure or element, such as a Chinese character's writing letter, Japanese "Kana", a phonetic alphabet, or a predetermined code or figure, is unclear and difficult to determine, the present invention treats this as a special code.

As shown in FIG. 1, when the identification symbol 29, the auxiliary variable 30, and the special code symbol 31 are input to the stroke calculating device 16, the special code symbol 31 from the special code memory 31 is entered. The special code data corresponding to) is extracted, and other auxiliary variables are also substituted to generate the character, and the coordinates 22 of each dot corresponding to the corresponding code are calculated.

Then, the vector signal 24 is transferred to the vector signal 24 via the video signal generator 23, and the vector signal 24 is converted into predetermined magnetic signals 26, 26 ', 26', and 16 '. Switch to). 35 to 38 are examples for reference only.

In addition, as shown in FIG. 1, in order to convert the vector signal 24 into a predetermined shape signal, a character or special code can be drawn using the high resolution drawing device 25, and the dot matrix computing device 27 The dot matrix signal 32 is switched so that the dot matrix signal 32 can be filled within the contour range of a character or a special code, and the high-resolution outer foot device 28, for example, a brown tube, etc. It can also be made to appear through a recording apparatus such as a video tube, a magnetic tape, a magnetic disk, or the like.

Next, the character "通" is described as an example. In the case where the character of "通" is intended to be expressed in a normal size (40 x 40), the letter-shaped symbol 150 is (0), and the character of the character The ratio with the width of the length is (1) (normal size).

It demonstrates, referring FIG. 1 and FIG. When the character signal 10 for character selection is input to the code memory 11, the code 1086 of the corresponding character is called from the code memory 11 and input to the character table memory 12, and the character table memory Resource symbol (245 + 18 = 272) and stroke of resource (之) based on resource group (之) and stroke group (-1) of "通" from address (6639) corresponding to the character in (12). Read the stroke separators (53, 47, 2, 10, 17, 17, 4) and send it to the stroke calculator (16).

Next, to select the length of a character, you must enter 241 (character length identifier) and 40 (character length value) as auxiliary variables. In addition, 242 (identification code for each shape) and 0 (character shape symbol for the carrier) must be entered to select the child type. If you are creating characters in normal size, you do not need to enter any other auxiliary variables.

A stroke calculating device (272), a stroke identification symbol (53, 47, 2, 10, 17, 17, 4), an auxiliary variable 24140 of a character length, and an auxiliary variable 2420 of a shape type together 16, the key point of the stroke corresponding to the stroke symbols 53, 47, 2, 10, 17, 17, and 4 is read from the stroke table memory 17, and the stroke calculating device is read. Call the program corresponding to the stroke written in (16) to calculate the dot coordinate of each stroke outline. At the same time, the stroke symbols 45, 56, 57, and 77 of the strokes containing the resources corresponding to the resource identifiers 13 are read from the resource table memory 21, merged with the shape symbol (0), and together with the stroke mark memory. Is sent to (17).

As described above, the key point of the stroke corresponding to the stroke symbols 45, 56, 54, and 77 from the stroke table memory 17 is read out, and the stroke corresponding to the stroke stored in the stroke operation 16 is read. A program is called to calculate the dot coordinate 22 of the outline of each stroke.

In this way, each stroke is simultaneously calculated, and the dot signal of the entire character is calculated by accepting a designation such as the length of the character as an auxiliary variable by a program operation. The video signal generator 23 is then converted into a vector signal 24 as described above.

Next, a circuit of the character generator of the present invention will be described with reference to FIG. 1A. In FIG. 1A, the character generator 1 of the present invention (the parenthesis numerals represent the symbols in FIG. 1). The first CPU 2 constituting the memory control device, the code memory 11, and the children A first ROM 3 constituting the table memory 12, an auxiliary variable memory, a second ROM 4 constituting the stroke table memory 17, a resource table memory 21, a special code memory 31, and the first CPU. A first data latch 5 for temporarily storing data called from the first ROM 3 by (2), a second CPU 6 constituting the stroke computing device 16, and a video generating device 23; The filler 8 which comprises the curve generator CG 7 and the dot matrix calculation apparatus 27 is used as a component.

First, the functions and roles of each element of the circuit are explained.

The first CPU 2 is for controlling the memory, and the character input 10 for character selection is input to the input means 2A to call the corresponding character code from the code memory 11 using the first ROM 3 and to make the first character code. The data is stored temporarily in the data processing 5 and read out by the second ROM 6, and the auxiliary variable 15 for character shaping selection is inputted from the input means 2A in the same way, and the shape is determined by the shape 29 and size. (30), the special code 31, the resource code 13, and the address code corresponding to the code 14 are sequentially called from the first ROM 3, and temporarily stored in the first data latch 5; While inputting the data, the second CPU 6 is sequentially input.

The second CPU 6 corresponds to the schedule memory 17, the resource table memory 21, and the special code memory 31 of the second ROM 4 in accordance with the address record read from the first data latch 5. FIG. The dot coordinate 22 of the stroke outline of the corresponding character is calculated based on the program which calls data and computes the dot coordinate 22 of the stroke outline.

The curve generator (C G) 7 generates the vector signal 24 by calculating the dot back touch of the stroke outline based on the conversion value of the dot coordinate 22 of the stroke outline sent from the second CPU 6. The curve generator 7 uses ROM for character typefaces in the same way as a conventional collector generator (character generator = CG), but differs from the conventional one in that the dot pattern of the stroke outline is stored.

The filler 8 receives the vector signal 24 representing the dot back touch of the stroke outline from the curve generator (CG) 7 and converts it into a dot matrix signal 32 which fills the dot in the stroke outline, and then temporarily The memory is sent to a temporary storage RAM (random access memory) 9 constituting the storage device.

The temporary storage RAM 9 temporarily stores the dot matrix signal 32 formed by the filler 8, and the vector signal 24 calculated by the curve generator 7 is used as needed to form a special shape. After being read by the 2CPU 6, it is stored in this temporary storage RAM 9 through the multiplexer 9A and multiplexer controller 9B described later.

The port decoder 2C converts the address sent from the first CPU 2 into control signals L1, L2, and L3 for data exchange between the second CPU 6 and the temporary storage RAM 9.

The first data latch 5 receives and temporarily stores data on the CPU-1 data bus and prepares for reading from the second CPU 6. The I / O port decoder 6A transmits each control signal R1, R2, R3, W1, W2, W3, W4, W5 based on the address sent from the second CPU 6.

The second data latch 5A temporarily stores the setting parameters sent from the second CPU 6 and monitors the operation state of the curve generator 7.

The multiplexer 9A is for allowing various data stored in the temporary storage RAM 9 to be stored or read from the first CPU 2 or the second CPU 6 or the filler 8, and the multiplexer A line and the multiplexer B The line determines which one can be stored or read from the temporary storage RAM 9.

The multiplexer controller 9B outputs the multiplexer A signal and the multiplexer B signal by controlling the multiplexer 9A by the second CPU 6 sending a selection signal through the W3 of the I / O port decoder 6A. . In addition, 8A, 8B in a figure are buffers, fulfilling the role of an interface, and (9C) in the figure are AND gates. Next, the operation of the character generator of the present invention will be described with reference to FIG. 1 and FIG. 1A based on the above elements. The description will be divided into "vector operation" which calculates "general operation" and special shapes, and will be explained step by step for easy understanding.

<General operation>

[Step 1]

When the character input 10 of a specific one character is performed by the input means 2A such as a key board, a mouse or a digitizer, the code memory 11 and the tabular memory 12 are formed by the first CPU 2 constituting the memory controller. ) And the corresponding character code is called from the first ROM 3 constituting the auxiliary variable memory 15.

The first CPU 2 receives the corresponding character code to the first data latch 5 through the L1 line of the port decoder 2C, and at the same time, the character code is received from the first data latch 5 via the interrupt line. Informs the second CPU 6 of the input.

단자가 0의 값을 나타낼때는 앞에 기억된 데이터가 아직 존재하고 있다고 설정한다면 제1CPU(2)는 플래그의 값이 1로 될 때까지 가다려서, 다음 문자코오드를 제1데이터 래치(5)에 기억되도록 할 수 있다.The first CPU 2 reads a flag indicating the system state of the first data latch 5 from the third data latch 5B through the L2 line of the port decoder 2C before sending out the character code. This flag is set, for example, when the DE terminal of the third data latch 5B indicates a value of 1, the first data latch 5 does not store anything, and only in this case, the first CPU 2 generates a first flag. 1 Write data to the data latch 5 and

When the terminal indicates a value of 0, if the previously stored data is still present, the first CPU 2 waits until the value of the flag becomes 1, and stores the next character code in the first data latch 5. You can do that.

Other codes such as the type of character, the length of a character, the thickness of a stroke, the ratio of the length of a character to the length of a character, or a special code, such as a special code, are also applied by the first CPU (2). Is sequentially called from the first ROM 3, and the above-mentioned flag is checked to be sent to the first data latch 5 so that data does not overlap all the time.

[Step 2]

When the second CPU 6 is notified that the character code is written in the first data latch 5 by the INT line between the first data latch 5, the second CPU 6 of the I / O port decoder 6A The character code stored in the first data latch 5 is read out one by one through the line (R2).

In addition, each time the second CPU 6 reads one data from the first data latch 5, it sends a signal to the third data latch 5B so that a flag indicating that data has already been read from the first data latch 5 is issued. . In this way, the first CPU 2 provides the second CPU 6 so that the codes for the characters do not overlap one by one.

[Step 3]

After the second CPU 6 has completely read a set of character codes, each data of the corresponding resource, stroke, or special code in the resource table, the stroke table, or the special code table in the second ROM 4 according to each code. And a change value of the dot coordinates 22 of the stroke contour is calculated according to the program corresponding to the code corresponding to the auxiliary variable 15 at the same time.

After the completion of the calculation, the change value of the dot coordinate 22 of the stroke contour is sent to the input buffer INPUT BUFFER through the W1 line of the I / O port decoder 6A.

The second CPU 6 checks whether the input buffer of the curve generator 7 is empty before outputting the change value of the dot coordinate 22 of this stroke outline, and sends data only when it is empty.

If the next data is sent when there is still previous data in this input buffer, the data is lost and the second CPU 6 waits until the input buffer is empty and sends the next data.

[Step 4]

After receiving the change value of the dot coordinate 22 of the stroke outline, the curve generator 7 immediately sends a flag during data input to the input buffer and prevents data transfer from the second CPU 6. Next, the curve generator 7 first arrests whether one set of calculations is completed, and if it is completed, starts another set of calculations.

After the operation is completed, the VALID terminal is set to 1 to flag that the vector signal 24 relating to the dot coordinate of the stroke outline can be output from the output buffer (OUYPUT BUFFER), and the internal operation is performed by the filler 8 or The second CPU 6 pauses until the vector signal 24 is read.

After the vector signal 24 is read, the curve generator 7 immediately indicates that the flag value of the VALID terminal is 0 and cannot be output, and resumes the internal calculation.

[Step 5]

When the filler 8 confirms that the curve generator 7 has the VALID terminal 1, the signal is output from the REQ terminal, and the curve generator 7 reads the vector signal 24 on which the calculation has been completed. The signal 24 converts the dot matrix signal 32 into which the dot outline is filled with dots.

This dot matrix signal 32 is sent to and stored in the temporary storage RAM 9 through the multiplexer 9A. Also, when the first CPU 2 or the second CPU 6 needs to write or read the temporary storage RAM 9, the second CPU 6 must always use the W3 of the I / Q port decoder 6A. A signal is sent to the CP terminal of the multiplexer control 9B through the terminal to control the multiplexer A and the multiplexer B to control the multiplexer 9, and the second CPU 6 transmits the temporary storage RAM 9 through the multiplexer 9A. And a hold signal is sent to the filler 8 through the second data latch 5A to stop all operations of the filler 8 to prevent loss of data.

[Step 6]

By repeating step 5 several times, the outline of the stroke is filled once by the dot, and the complete shape processing is completed.

[Step 7]

After the second CPU 6 inputs all the change values of the dot coordinates 22 of the stroke outline into the curve generator 7, the dot matrix signal (or the dot matrix signal) is again determined by the filler 8 to determine whether or not the calculation of the vector signal 27 is completed. 32) constantly monitoring whether the conversion is complete.

After the dot matrix signal 32 is completed, the completion signal is transmitted to the first CPU 2 via the first data latch 5, and the dot matrix signal 32 is temporarily stored in the temporary storage RAM 9. Notifies that can be read.

When the first CPU 2 can read data from the temporary storage RAM 9, the release signal is sent from the second CPU 6 to the first CPU 2 via the data bus and the address bus, The 2CPU 6 issues a hold signal from the second data latch 5A to stop all operations of the filler 8 in order to prevent data loss.

[Step 8]

The first CPU 2 reads the completed dot matrix signal 32 from the temporary storage RAM 9, and one character generation process is completed.

The dot matrix signal 32 read by the first CPU 2 is output through an output means 2B using a high-resolution out foot device 28 or the like, and the CRT as a character 26 or a special code 26 ". It is exhibited by an image tube (CRT), a high resolution printer, or the like.

<Vector operation>

In order to generate a special shape such as enlarged characters at an angle, a special vector operation needs to be performed. Therefore, the calculation program of the corresponding shape is executed through the W2 line of the second CPU 6 I / O port decoder 6A. It is sent to the latch 5A, read by the curve generator 7, and the vector signal 24 corresponding to the program is calculated.

This vector calculation process will be described below step by step.

[Step 1]

Step 4 is executed from "Step 1 of the general operation".

[Step 2]

The second CPU sends the change value of the dot coordinate 22 of the stroke outline to the curve generator 7, and when the VALID terminal of the curve generator 7 becomes 1, the vector signal 24 outputs the outer foot of the curve generator 7. The second CPU 6 reads the vector signal 24 via the R1 line of the I / O port decoder 6A because it is stored in the buffer at any time. After the vector signal 24 is read by the second CPU 6, the curve generator 7 indicates that the flag value of the VALID terminal cannot be immediately outputted to 0 and continues to perform internal calculation.

[Step 3]

By repeating step 5 of "normal operation", the filler 8 completes the dot matrix signal 32 and sends the dot matrix signal 32 to the temporary storage RAM 9 by the second CPU 6 to transmit the dot matrix signal 32. ).

[Step 4]

After reading the dot matrix signal 32, the second CPU 6 adjusts the dot coordinate of the stroke outline of the dot matrix signal 32 according to a program based on a character code sent from the second CPU 2, do.

[Step 5]

The second CPU 6 passes through the multiplexer A and the multiplexer B through the I / O port decoder 6A and the multiplexer controller 9B, and controls the multiplexer 9A for the temporary storage RAM 9. RAM 9 for temporary storage of the dot matrix signal 32 adjusted by a special self-adjustment by using the W5 line and AND gate 9C of the I / O port decoder 6A while securing the right to access.
