Abstract

PURPOSE:To enable printing in a balanced space between characters, by determining each space between characters corresponding to the combination of the front and the rear characters and the kind of a character when plural kinds of characters such as em, half-em, double-em are present in a mixed state. CONSTITUTION:When a pitch between em characters is set to 8 dots while a pitch between half-em characters is set to 4 dots, a pitch between the em character and the half-em character is set to 6 dots regardless of the front and rear relation thereof. This determination is carried out by a first register 1031 storing the information in the character kind of the preceding character written in a line buffer 104, a second register 1032 storing the succeeding character kind subsequently written in the line buffer 104, a means calculating space data between characters inherent to the combination of the preceding and the succeeding character kinds from the informations of each character kinds stored by said register 1031, 1032 in writting in the pattern data of the succeeding character in the line buffer 104 and a means for writting in the space data between characters in the line buffer 104.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is used for a printing device.
This invention relates to a character spacing 1m4111 device suitable for use in a dot printer that is capable of printing a mixture of characters with different character types, such as 0 x 0x character.

[Technical background of the invention and its problems]

Conventionally, in dot printers, full-width and half-width.

When printing a character string containing a mixture of various characters, such as double-width characters, in horizontal writing, the pitch between each character is determined by giving each printed character a space specific to that character type. For this reason,
Between different types of characters, such as full-width characters and half-width characters, full-width characters and double-width characters, and half-width characters and double-width characters, the character arrangement is uneven, making it impossible to allocate space between characters in an efficient manner.

Figure 1 shows an example of the conventional printed character pitch in this case. In this example, a space of 8 dots is given after the makitori character, and a space of 4 dots is given after the half-width character. It shows. Here, between full-width and half-width characters, when a half-width character is printed after a full-width character,
This indicates that when a full-width character is printed after a half-width character, there is a shift in the space between characters.

In this way, conventionally, each printed character is uniformly given a unique inter-character pitch (full-width, half-width, single-width, etc.), which makes it impossible to harmoniously allocate the space between dead characters. There was a drawback.

[Purpose of the invention]

The present invention is based on the above-mentioned circumstances, and includes full-width characters,
When printing characters in which multiple types of characters with different - characters, such as half-width characters and double-width characters, are mixed, the space between characters is always balanced by distributing spaces between nine characters (- spaces). The purpose is to provide a control device.

[Overview of the invention]

The present invention has different character widths, for example, full-width characters.

When a plurality of character types such as half-width single-width characters coexist, the space between each character is determined according to the combination state of the character types of each pair of characters *'i before and after the space. To give a specific example, the pitch between full-width characters is 8.
If the pitch between dots and half-width characters is 4P, the pitch between full-width and half-width characters is 6 dots even if there is a half-width character after a full-width character or a full-width character after a half-width character. do. That is, as a basic example, when a half-width character is printed on the same line following a full-width character, it is printed at 1/2 dot (4 dots) of the full-width character pitch and 1/2 the half-width character pitch.
! Dot (2 dots) is added, giving a total of 6 dots as space between characters. On the same machine, when a full-width character following a half-width character is printed on the same line, the half-width character pip is 1/
2 Pts (2 dots) plus 1/2 dot (4 dots) of full-width character pitch for a total of 6 dots, or 1/2 of half-width character pitch when gyu-kaku characters are printed consecutively. Bits (2 dots) and v2 dots (2 #p dots) of the same gyu-kaku character pitch are added for a total of 4P)1. Each character spacing is given as a space (-s). Control of this character spacing (-s) When the subsequent character/natern data is written to the line buffer following the preceding character/aturn data, K is written based on the pair of character type information corresponding to each of the above characters/aturn data.

The number of dots in the space between characters as described above is determined,
Space data (f rank data) according to the number of dots
This is done by writing the line buffer to the line buffer.
