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 text from a keyboard etc. and prints it out on a printer, but this device uses font name information that specifies the font of printed characters, and font name information that specifies the direction of printed characters. Direction information and character code information specifying printing characters are output to the printer, and the printer generates image information corresponding to these font name information, font direction information, and character code information, and also outputs font name information and font direction. information, first distance information indicating the distance from the bottom edge (or top edge) of the image indicated by the image information to the origin of the image corresponding to the character code information, and from the right edge (or left edge) of the image indicated by the image information. first position information consisting of second distance information indicating the distance to the origin of the image; and second position information indicating the positional relationship between the origin and the origin of the image indicated by the image information corresponding to the next printed character. The image forming apparatus is configured to generate positional information and print characters corresponding to the image information at a position specified by the first positional information and the second positional information.

For example, as shown in Figure 3, when printing the English letters "f" and "g",
First, image information corresponding to the letter "f" is generated, and the distance Y0 from the bottom of the image (area surrounded by a dotted line) indicated by the image information corresponding to the letter "f" to the origin C of the image , the distance X0 from the right edge of the image to the origin of the image, and the origin C of the image
to the origin C of the image indicated by the image information corresponding to the next printed character "g", that is, the distance YW
and the distance XW, and when printing the character "f", a line A intersecting at the origin C is generated.
And line B is printed as a baseline serving as a reference line in the vertical and horizontal directions of this printed character "f". Here, XS indicates the horizontal length of the image indicated by the image information corresponding to the letter "f",
YS indicates the length in the vertical direction of the image indicated by the image information corresponding to the character "f".

Further, when printing the next character "g", the character "g" is printed based on the next origin C determined by the information indicating the distance YW and the distance XW.

In the case of horizontal printing in which character strings are arranged and printed in the horizontal direction, the distance YW is generally set to zero, and the origin of each character is arranged on the baseline B, which is the horizontal reference line. In addition, in the case of vertical printing in which character strings are arranged and printed in the direction of the vertical frame, the distance XW is generally set to zero, and the origin of each character is on the baseline A, which is the vertical reference line. It will be arranged.

[Problem that the invention seeks to solve]

By the way, in conventional printer devices that print examples of Japanese characters, the first position information X0,
Y0 was set to the same value. Therefore, when printing the character ``atsuta'' in horizontal writing, for example, the character ``tsu'' will be printed correctly as shown in Figure 4a, but in vertical writing, the character ``tsu'' will be printed correctly. In Figure 4b, the character “tsu” should be at the bottom right of the character “a”.
As shown in the figure below, the image is printed on the lower left corner, and there was a problem that it was not possible to print in a beautiful layout.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a printer device that can print characters in a beautiful layout compatible with horizontal writing and vertical writing.

[Means for solving problems]

In order to achieve the above object, the present invention provides printing information corresponding to font name information that specifies the font of printed characters, font direction information that specifies the direction of the printed characters, and character code information that specifies the printed characters. an image information generating means for generating image information corresponding to a character; and a positional relationship between an image indicated by the image information and an origin of the image in correspondence with the font name information, the font direction information, and the character code information; positional information generating means for generating first positional information and second positional information indicating a positional relationship between the origin and the origin of the image indicated by the image information corresponding to the next printed character, and the image information In a printer device that prints characters corresponding to image information generated from a generation means at a position specified by first position information and second position information generated from the position information generation means, a baseline of printed characters is provided. an input means for inputting baseline direction information specifying the direction of the font, and a comparison between the direction of the baseline specified by the baseline direction information input by the input means and the direction of printed characters specified by the font direction information; , a determining means for determining whether the direction of the baseline and the direction of the printed characters are the same, and a changing means for changing the first position information and the second position information according to the determination result of the determining means. It is characterized by having been provided.

[Effect]

In the present invention, baseline direction information that specifies the baseline direction of printed characters is input, and the baseline direction specified by this baseline direction information is compared with the printed character direction specified by font direction information, If the direction of the baseline and the direction of the printed characters are the same, it is determined as horizontal printing in which the characters are arranged horizontally and printed, and if they are different, it is determined as vertical printing in which the characters are arranged and printed in the vertical direction. The first position information and the second position information are changed according to the determination result.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention. Interface 1 includes font name information that specifies the typeface of printed characters (Gothic, upper case, lower case sensitivity, etc.), and the direction of printed characters. Font direction information, character code information specifying printed characters, and baseline direction information representing the direction of the baseline of printed characters are input. Each of these pieces of information is provided, for example, from the main body of a Japanese language processing device (not shown).

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 stores address information as shown in FIG. 2a corresponding to each of a plurality of printable fonts, including the direction of printed characters. When receiving font name information and font direction information, address information B is output. This address information B is input to the font image information memory 3.

The font image information memory 3 includes four memory blocks MB() to MB() corresponding to printable fonts, as shown in FIG. , image information of Japanese vertically written characters and horizontally written characters is stored. Therefore, from the font switching circuit 2, for example, address information B corresponding to the font
is input, four memory blocks MB
MB() is selected from () to MB().
Then, by giving the character code information as lower address information, the memory block MB
Among the image information of English capital letters stored in parentheses, the image information of the character corresponding to the character code information is read out. 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 writing/horizontal writing determination circuit 5.

The vertical writing/horizontal writing determination circuit 5 determines horizontal writing printing if the direction of printed characters specified by the font direction information and the direction of the baseline indicated by the baseline direction information are the same, and determines vertical writing printing if they are different. If horizontal writing printing is determined, address information Y1 is output, and if vertical writing printing is determined, address information Y2 is output. These address information Y1, Y2 are supplied to the font position information memory 6 together with the address information B to B output from the font switching circuit 2.

The font position information memory 6, as shown in FIG. Furthermore, each memory block has sub-memory blocks SMB() to SNB() corresponding to the address information B to B output from the font switching circuit 2, and each sub-memory block stores the print characters by character code information. Information defining the position X0, Y0, Xw,
It stores Yw and size information Xs, Ys.
In this case, information X0 and Y0 are set to different values for each memory block.

In other words, information X0 to Yw is set to different values for vertical printing and horizontal printing. For example, when printing the character ``tsu'' in ``atsuta'' vertically, the value for the character ``a'' is set to different values. Information X0 and Y0 are set to be printed at the bottom right.

Therefore, when address information B to B corresponding to the font and address information Y1 and Y2 instructing vertical printing or horizontal printing are input into the font position information memory 6, the positional relationship of printed characters is determined according to these information. Positional information X0 to Yw that defines the is output for each character code. At this time, information Xs and Ys indicating the size of the characters are also output. These information X0~Ys
, Xs and Ys 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. The character information having this position information is input to the page image creation circuit 4, collated with the image information output from the font image information memory 3, and edited into image information for one line. 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 raster 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 is configured. Therefore, one line of image information edited by the page image creation circuit 4 is output to the printing mechanism 9 via the printer interface 8 for each horizontal scan 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 printing the character ``Atsuta'' vertically, the character ``Tsu'' will be printed at the bottom right of the character ``A''.
You can print text with beautiful layouts.

In the embodiment, the printing mechanism is of a raster 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. You can print beautiful layouts.
