Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a character output device such as a device for printing alphanumeric characters, kanji, hiragana, etc., and more particularly, to the configuration of a printing device and a computer that drives the printing device. , when the character code string assembled in the computer is processed as the entire image data of the character pattern corresponding to the character code, horizontal writing with the same character code string as input, as a document. A printing control device that is equipped with all the circuits that control the printing so that it does not extend beyond the print frame of the specified paper, whether printing horizontally or vertically, when performing printing control such as printing or printing as a vertically written document. It is related to.

[Prior art]

Hereinafter, a description will be given using a printer sound as a character output device.

In recent years, office automation (0[ficeAu
With the development of t, orn2tion: □A), Japanese documents were created and corrected in a computer system,
This is a method that is becoming more and more popular, using a printing device connected to a calculator.In this way, the advantages of creating and modifying Japanese documents using an electronic computer are This can be said to be due to the storage and reuse of large numbers of documents using Kan Inutani's memory function, and the improvement of printing quality using a high-quality, dual-speed kanji printing device (also called an A-character printer).

By the way, the kanji and hiragana expressed in 'kuzi calculation izan are 1. As specified in the ``O8C6226R Kanji Code System for Information Exchange'', the character code is 2 bytes long (1 byte is 8 bits). Furthermore, alphanumeric characters and the like contained in a Japanese document are represented by character codes of the conventionally known EBCDIK code, which are 1-byte long character codes.

Therefore, the character code string of a Japanese document containing a mixture of kanji and alphanumeric characters is a mixture of 2-byte g kanji codes and 1-byte length alphanumeric codes.

This character code string is sent to a kanji printing device connected to a computer, and the kanji printing device persistently extracts the character code string, extracts the character pattern corresponding to the character code from the character font dictionary, and creates image data. (also called dot data), the image output circuits are all driven. Character patterns in the character font dictionary are stored as image data of n dots vertically and m dots horizontally for each character size. Kanji codes have the same values for n and m, and are called full-width character codes. In the alphanumeric code based on the EBCI) IK code, m = n / 2, which is called a half-width character code. For example, 24
In the case of a dot character code, the full-width character code is vertically 2
9 is 4 dots in the horizontal direction and 24 dots in the horizontal direction.The half-width character code is 24 dots in the vertical direction and 12 dots in the horizontal direction. Therefore, in a horizontally written document, one full-width character code uses two half-width character codes.

Note that the alphanumeric characters of the double-byte character code may also exist in the kanji code.

FIG. 1(a) shows an example in which full-width character coded Kanji and Hiragana characters and half-width character coded alphabetic characters are mixed and printed as a horizontally written document. In FIG. 1(a), the image is correctly printed within the print frame. Now, there is a case where it is desired to print this same sentence 4 as a vertically written document. Sometimes electronic needle:
It is desirable to be able to print all vertically written documents while maintaining the arrangement of character code strings in gm as they are for horizontally written documents. For this purpose, it is considered that image data can be generated by rotating the entire character pattern 90 degrees N in the left direction within the kanji printing device.

With this method, if all character code strings are full-width character code strings, the printed result will fit within the print frame even if the character pattern is rotated 90 degrees to the left, but full-width and half-width character codes will be mixed. If there is, the printing frame will protrude, as shown in FIG. 1(b). Furthermore, (1
) Problems arise, such as the English letters are arranged in a row that is difficult to read, and (2) the parentheses are also rotated, so that the correct role of the parentheses is not υ.

[Purpose of the invention]

The purpose of the present invention is to solve all of these conventional problems by sequentially examining character code strings sent from a computer, and when printing a horizontally written document as a vertically written document, character patterns are all leftward 901 summer. It is an object of the present invention to provide a complete printing control device equipped with a control circuit for full rotation processing and pre-stop operation.

Specifically, the print control device of the present invention is configured to perform the steps shown in FIG.
The purpose is to enable the printing example shown in C).

[Key points of invention]

The print control device of the present invention converts a character code string sent from a computer into image data of a character pattern in units of character codes (full-width characters, half-width characters), and at the same time converts the character code string into character pattern image data. is a character code that can be rotated 90 degrees in the left direction and cannot be rotated.
It has the tH1 characteristic in providing a means to store all the character codes of 0 degree rotatable and non-rotatable in advance, and as a result of comparative inspection,
If there is a mismatch, the dot data of the character pattern is expanded vertically, and if there is a match, it is expanded horizontally. The feature is that it is controlled so that it can be printed as a handwritten document. Hereinafter, we will use +45Al using all the examples.

[Embodiments of the invention]

FIG. 2 shows an embodiment in which the essential parts of the present invention in a printing control device are fully illustrated. In the figure, reference numeral 1 indicates a register ♂ when receiving a character code string from an electronic computer, and 2 indicates a sub-command inspection circuit included in the data stream of character code data U.

ne pleld Char2Cter ■) 25 is a control character code and is not to be printed.

DATA26 is a character code string to be printed.

In 5UB22, the size of characters to be printed, font, horizontal document printing, vertical document printing, etc. are specified.

Referring again to FIG. 2'fc, the data stream shown in FIG. Sent on L2. In the subcommand detection circuit 2, the control hide Q (Control
1 Byte Q: CBO) 21'a: Once detected, the next data becomes a subcommand 80B22, and the 5UB22 control code is decoded. If the "City 1" code is "Horizontal document printing", the signal transmitted through the signal source L4 will be "0", and if it is "Vertical document printing", it will be logic "1". Note that, depending on the control code of 5UB22, the signal on the signal line $L3 becomes logic "1" or cooking "0".

Next, in the data stream shown in Figure 3, 5UB
The order of control character codes following 22 is FH2a, I)
FCI 24. After confirming that DFC, lI25, the signal fm of signal line L7 is set to "1" (AI) 84'f
It is positioned at the beginning of buffer 3 as co. Also, by setting the signal ktm of the signal line L6 to "1", the gate 1
1 is opened, DATA 26 is sequentially stored in character code storage buffer 3 via data bus L2. The storage address is designated by the ADR 4, and is sequentially added by the incrementer 17. Calo calculation is triggered by a signal on signal line L8.

When the entire data stream sent out from the computer is stored in the buffer 3, the AD converter 4 is reset again and the process of converting the character code into the character font/pattern is started. Characters are taken out of buffer 3 one by one and sent to data bus L9. Addressing of buffer 3 is done with ADR4. The character code on data bust 9 is stored in character font storage memory 6 and data register DR.
Enter 5. The character font storage memory 6 stores character font patterns that correspond to character codes.
They are dot data. Here, dot data is the direct result of bits such as "0" and "1". For example, 24 vertical dots.

If the dot data is 24 dots horizontally, the data will be 1056 bits long.

The dot data of the character font pattern is sent to L(RE G
It is held at 9. If it is "side-hot document printing", the signal on the signal line L4 is cooking "0", so the AND circuit 14
The signal on the signal line L12, which is the output of
The gate 12 is opened and data is stored in the double-open data buffer 10 row by row. On the other hand, if "vertical printing" is specified, the signal on signal line L4 becomes logic "l", and signal line -
When the signals on I and 11 become cooking "L", the signals on signal lines 1 and 13, which are all f4 in the AND circuit 14, become logic rB and the gate 13 is opened. At this time, the dot data held in RRE o 9 is stored in the image buffer 10 column by column.

The dot data stored in the image data buffer 10 is taken out line by line and sent to the bidet number 1g generation circuit 15.
After processing, the laser beam printer drive circuit 1
6, the image data is printed. therefore,
Gate 12-i is the first character font pattern.
As shown in Figure 1(a), the font pattern of the characters added to the gate 13' is as shown in Figure 1(b) or (C). Printed as a vertical document.

In the control system of the present invention, when vertical printing is performed, (C
) has a built-in control circuit for printing. That is, the character code held in the D box 5 is compared with the character code registered in the (a) tightening rotation inhibition code storage memory 8 one song at a time. The comparison is performed by comparator 7. As a result of the comparison, if the code is other than the rotating regular character code, the signal #L11 becomes logic "1", and the AND circuit 14 performs a logical product between the signal and the signal dL4. As a result, the signal of the first signal ML13 becomes logic “1” υ
, gate 13 will be opened. On the other hand, when the rotation is prohibited character, the signal on the signal line Lll becomes logic "o",
As a result, the signals on signal lines 1 and 12 become logic "1".

In addition, there are several character codes written in the ordinary memory 8.

Registration in the rotation-inhibited character code storage memory 8 is accomplished by finger cooling from an electronic computer and the data stream shown in FIG. When the subcommand inspection circuit 2 fully recognizes that the character code is to be registered in the S[JB22 check-C network memory 8 in FIG. Yuno, store in Gi 3 memory 8.

As is clear from the above description, according to the present invention, even if processing 1 to -1 of the character code string for horizontal printing is performed for vertical printing, the printing frame is It can be printed without any gold overflowing.
