Abstract

PURPOSE:To print a multi-linguistic sentence including Japanese in well-arranged layout by switching position information in accordance with the comparative results of printed character direction and base line direction. CONSTITUTION:Font direction information and base line direction information which were inputted from an interface 1 are supplied to a vertical/lateral printing decision circuit 5. Address information from the circuit 5 is applied to a font position information memory 6 together with address information which is outputted from a font switching circuit 2. The font position information memory 6 stores information XO, YO, XW, YW to prescribe the position of printed character by character code information and information of character size XS, YS. Information XO-YW is set at a different value according to the cases of vertical printing and lateral printing. For instance, when characters are vertically printed, any symbols can be added slightly off the alignment forming the well-balanced appearance as a whole. Thus it is possible to print a sentence in well-arranged outlay using each information XO-YW.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device used in a Japanese language processing device or the like.

[Conventional technology]

Conventionally, there is a processing device that inputs Japanese or English sentences from a keyboard or the like and prints them out using a printer, but in this device, the first information that represents the font of the printed characters, and whether the printed characters are written vertically or horizontally. The second information and the third information representing printed characters are outputted to the printer device, image information corresponding to the first to third information is generated on the printer device side, and further the second and third information are outputted to the printer device. generate first position information representing the positional relationship to the leftmost (or rightmost) image with respect to the origin of the printed character image and second positional information representing the positional relationship with the origin of the next printed character image based on the The image information is configured to be printed at a position specified by first and second position information.

That is, for example, to explain the case of printing the English characters "f" and rgJ, as shown in Figure 3, "fJ
and "g" image information, as well as the X direction (horizontal direction) to the lower left end image with respect to the origin C, which is the intersection of baselines A and B, which are the reference lines in the vertical and horizontal directions of printed characters. The length Xo, the length Yo in the Y direction (vertical direction) from the origin C to the lower left image, the X direction and Y distance between the origin C of the current printed character rfJ and the origin of the next printed character "g" Generate positional information of lengths Xw and Yw in the direction, and use these positional information and information Xs and YS representing the size of the printed character to print the printed character at the position specified by each positional information. It is configured.

[Problem that the invention seeks to solve]

However, conventionally, the first position information X, Y, and the second position information YW are set to the same value whether horizontally written characters are printed or vertically written characters are printed. For this reason, when printing the character ``Ata'' in horizontal writing, for example, the character ``tsu'' is printed correctly, as shown in Figure 4 (a), but in vertical writing, the character ``r'' is printed correctly. The character "A" should be printed at the lower right of the character, but as shown in FIG. 4(b), it is printed at the lower left, resulting in a problem that it is not possible to print in a beautiful layout.

[Means for solving the problem 1] The present invention compares the direction of the baseline indicating the reference position in the vertical direction of the printed character with the information indicating the direction of the printed character, and if the information is in the same direction, it is determined that the character is horizontally written. , if the information is in a different direction, it is determined as a vertically written character, and the position information that defines the position of the printed character is changed in accordance with the result of this determination.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention. Interface 1 includes font name information (first information) representing the typeface of printed characters (Gothic, upper case, lower case sensitivity, etc.), printed characters Font direction information (second information) that indicates whether the direction is vertical or horizontal, character code information that indicates the printed characters (third information), and a baseline that indicates the reference position of the printed characters in the vertical direction (Fig. 3). Baseline direction information (fourth information) representing the direction of line B) is input.
[ru. Each of these pieces of information is given, for example, from the main body of the Japanese language processing device.

Among these pieces of information, font name information and font direction information are input to the font switching circuit 2. The font switching circuit 2 includes the distinction between vertical writing and horizontal writing,
Figure 2 (a) corresponds to each of the plurality of printable typefaces.
), and for example, when receiving font name information and font direction fW information specifying font I out of font I - font ■, address information B is stored.
Outputs I. This address information -4B■ is input to the font image information memory 3.

The font image information memory 3 stores Wary 2 (b) K
As shown, it is equipped with four memory blocks MB(I) to MB(IV) corresponding to the printable fonts I to IV, and each memory block has 9 uppercase and lowercase English letters.
It stores image information of Japanese M-written characters and horizontally written characters. Therefore, when address information BI corresponding to, for example, a typeface is input from the font switching circuit 2, MB (of the four memory blocks MB(I) to MB(IV)
I) is selected. Then, by giving one character code information as lower address information, image information of a character corresponding to the character code information is read out of the image information of English capital letters stored in memory block MB(I)K. This image information is composed of m×n (m, an integer of n≧2) pixels, and is supplied to the page image creation circuit 4.

On the other hand, font direction information and baseline direction information input from the interface 1 are supplied to the vertical/horizontal writing determination circuit 5.

If the direction of the printed literature indicated by the font direction information and the direction of the baseline t indicated by the baseline direction information are the same, this judgment circuit 5 judges the printed character as a horizontal writing character, and if they are different, it judges it as a vertical writing character. If it is determined to be a horizontally written character, address information Yl is output, and if it is determined to be a vertically written character, address information 's Y * is output. These address information Yg and Yt are address information BI-BI output from the font switching circuit 2.
It is supplied to the font position information memory 6 together with V\.

As shown in FIG. 2(C), the font position information memory 6 stores memory blocks M B (Y,) to MB (
Each memory block further includes submemory blocks SMB(I) to 8MB(IV) corresponding to address information BI to BIV output from the circuit 2,
Each sub-memory block stores information X, , Y, , XW, Yw defining the position of printed characters and size information Xs, Ys on the character code information side. In this case, information X. IY, , Xw, and Yw are set to different values for each memory block. In other words, information X0 to YW is set to different values for vertical writing and horizontal writing.
For example, when printing the character ``tsu'' in ``at'' vertically, each piece of information
~Yw is set.

Therefore, the font position information memory 6 contains address information BI-BIV corresponding to the font and address information Y1 . When Y is input, positional information X0 to Yw defining the positional relationship of FD n'11 characters is output for each character code according to this information. At this time,
Information XS indicating the font size.

Y3 is also output. These information X, ~Yw and X,
, Y are input to the positional character information synthesis circuit 7, where they are combined with character code information and output as character information with positional information. This character information with position information is input to the page image creation circuit 4, and is compared with the image information output from the font image information memory 3.
Edited into lines of image information. Then, the edited image information for one line is output to the printing mechanism 9 via the printer interface 8 for each scanning line. That is, the printing mechanism 9 is a rask scan type printing mechanism that sequentially scans and prints an image in which one character consists of m)<n pixels from the pixels of the first scanning line in the horizontal direction to the pixels of the nth scanning line. It consists of For this reason, the image creation circuit 4
One line of image information edited in is output to the printing mechanism 9 via the printer interface 8 for each horizontal scanning line. This prints one line of characters.

In this manner, in this embodiment, the information X0 to Yw defining the positional relationship of the printed characters is switched according to the comparison result of the information indicating the direction of the baseline and the direction of the printed characters, respectively. Therefore, when writing the character ``Ata'' vertically, the character ``TS'' is printed at the bottom right of the character ``A'', making it possible to print a sentence with a beautiful layout.

In the embodiment, the printing mechanism is a rask scan type, but it may be a printing mechanism that prints character by character.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the position information is switched according to the comparison result of the information indicating the direction of printed characters and the direction of the baseline, so that text in multiple languages including Japanese can be edited. You can print beautiful layouts.
