Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an information output device that outputs recorded information to a recording device.

BACKGROUND ART In the past, various devices have been developed and proposed for outputting information using, for example, electrostatic recording devices using laser beams, optical fibers, etc., ink jet recording devices, dot impact recording devices, CRT display devices, etc. . .

For example, when recording a text, the fni information output device sequentially outputs recorded information several times from a storage device such as a magnetic tape (MT) or a magnetic disk. Based on this, a character code is continuously output for each line in the raster scanning direction of a laser beam, etc., and the necessary character signals are generated accordingly for all character recording operations.

However, the character size in conventional information output devices is fixed, for example, 16×16 dots, and has the disadvantage that it is not possible to record all the character sizes that fit the paper size.

OBJECTS OF THE INVENTION An object of the present invention is to enable recording in a character size that matches the paper size, and to eliminate the drawbacks of the above-mentioned conventional examples.

06 and 107, and a character size control device 108 that controls the character size based on the paper size specification from the arithmetic processing device 101 described above.

The operation of the information output device InD having the above-described configuration will be explained.

One page of text information is output from the processing unit 101 to the information output device InD, and under the control of the first control unit 106, the receiver receives instructions from the processing unit 101 to send the received text information via the interface 102'z. It is stored in the first page storage device 103 as an image of paper size. First control unit 10
6 receives the text information from the first page storage device 103 and transfers the information sound of the first page storage device 103 to the second page storage device 104. The second control unit 107 stores the character code information in the second page storage device 104 line by line in the recording device 105.
The recording device 105 generates necessary character signals according to the character information and performs recording.

The first control unit 106 and the second control unit 107 execute processing asynchronously, and are synchronized only when transferring data between the page storage devices 103 and 104.
While outputting the information in the page storage device 104 to the recording device 105, the first control unit 106 can perform parallel processing of loading data from the arithmetic processing device 101 to the first page storage device 103. The first control unit 106 mainly performs the process of registering characters and storing text information in the first page storage device 103 according to the format and paper size, and the second control unit R107
05 and the text information in the second memory storage device 104, outputting each line to the recording device 105 is performed.

FIG. 2 is a block diagram based on the information flow of the system shown in FIG. 1, in which the first control device 201Fi, the interface 102 shown in FIG.
3. A first control device including a first control unit 106;
According to instructions from the arithmetic processing unit 101, information such as data, print signals, paper size, etc. is inputted, and a wait signal is sent to the arithmetic processing unit #101 while the information is being input to the storage section of the first page storage device 103. Output and arithmetic processing unit 1

The second control device 202 is a second control device including the second N storage device 104 and the second control unit 107 shown in FIG. , paper size, etc., and after inputting the information, the dC recording device 105 finishes recording the information, outputs a wait signal to the first control device 201 until the ready status is input, and then displays the next page. Temporarily stop the transfer of recorded information. The character size control device 108 includes a character size control section 108a and a character generator 1osb,
The character size control unit 108a determines the character size according to the paper size and controls the character generator 1 accordingly.
The font pattern address of 08b is output to the character generator 108b, and the character generator 108b sends the addressed font pattern to the character size control section 108a. Character size control unit 108a
Then, this font/1,000 turns is output to the recording device 105.

Next, the operation of the apparatus shown in FIG. 2 will be explained.

The arithmetic processing unit 101 outputs information such as character information (data), print signals, paper size information, and font patterns to be registered in the character generator to the control unit 201 as text information. The first control device 201 creates a page image of character information (data) and stores it in the built-in storage device 103 (FIG. 1), and when the processing for one page is completed, a print signal from the arithmetic processing device 101 is sent. Upon input, all of this text information is transferred to the storage device 104 of the second control device 202.Furthermore, the font data t from the arithmetic processing device 101 is transferred to the storage device 104 of the second control device 202.
108a's character generator.

The second control device 202, which has received one page of text information, sends the paper size to the character size control section 108a. When the character size control device (FIG. 1 108) receives the paper size, it holds it as a dot constant total counter corresponding to the paper size, and accesses the font pattern corresponding to the code in the character generator 108b accordingly.

FIG. 3A is an example of the character font in the actual character generator 108b, and this character font is 10 dots x
IO dot font υ, vertical dot VERTI
CAL DOT (VDOT), side)'tsu)kHOR
We will call it IZONTAL DOT (HDOT). Assume that access is performed from 6o to 99 (10 dots in total, 10 dots) as shown in FIG. 3B. In FIG. 3A, aFicG access start address, b the CG END address, C the CG TOP address, and d the CG access end address.

In this case, 7 onts of characters are registered in the character generator 108b in advance as 10 dots x 10 dots, and during actual printing, HDOT=10°VDOT=1
If 0 is specified, the character size control unit 108a performs control so that the character generator 108b is accessed in the access order as shown in FIG. 3B.

Next, all details of the access to the character generator 108b performed by the character size control unit 108a will be explained.

Character generator 108 bid The memory size for each character is configured in units of 1 box of 32 dots x 16 dots as shown in FIG.

The addresses are arranged from address 0 to address 3F as shown in FIG. In addition, each address Fi is composed of 8 bits as shown in FIG.
~7 are the upper 4 bits. Normally, when displaying with 32x16 dots, access to the character generator 108b is as shown in Figure 5 A (7), the top 4 dots of address F

The memory is accessed in the following order: OL), lower 4 bits of address 20 (2OL) lower 4 bits of address 30) (301,').

The access control by the character size control unit 108 & is performed using the vertical dot (vertical dot) i (VERTICAL DO) determined in advance based on the paper size signal from the second control device 202.
T-VDOT) and the number of horizontal dots (HORIZONTAL)
DOT-HDOT). For example, VDOT=24.

When HDOT=12, first, the address of the character generator i osb is determined from the character code, which is 0 in Figure 4.
Know the address of the address (the @ position of the corresponding box). Next, start from address 0 L, 1 line 2 scans, add address (T--1) to address 0, calculate the first read B address of the character generator 108b, and calculate the top 4 of that address. Read bit. Next, 10 addresses (hexadecimal) are added to that address to calculate the next read address (adjacent address ffl', address 18 in FIG. 4). At this time, only the upper 4 bits of the address address are read out, and HDOT=12 is set to 4 (one read).
After reading out the contents of the address that number of times, the lower 4 bits of the first read address are read out. When the reading of this line is completed, 1 is decremented from the first read address and the upper 4 bits are read in the same manner. This ff1VDOT=2
Divide by 4i2 1) Repeat 12 times. This access is illustrated in FIG. 5B.

This VDOT, HDOT (7) designation N: Paper size control is performed according to the paper size control information stored in the second control device 202.

FIG. 6 is an operation flowchart of the character size control section (FIG. 2 108a). First, the character size (vertical...VD) corresponding to the paper size sent from the second control device 202 is

Output T times (step 309). If this is passed back to VCNT (step 308), the font pattern will be output in the access order shown in FIG. 3(B)K.

In this example, the font size is set by fixing VDOT and HDOT according to the paper size, but it is possible to change the font size even if the paper size is the same, and the control code indicating the font size is included in the character code. By adding , the font size can be changed freely even within the same page.

Furthermore, by keeping the font size constant and changing only the spacing, it is possible to output text that is easy to read.

Effects As explained above, even when record information is sent from the arithmetic processing device, the font size is automatically set according to the paper size, making it possible to always output in easily legible fonts and turns.
