Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device for appropriately controlling the number of dots forming blank portions between character patterns in a dot matrix printer.

[Technical background of the invention]

For example, as shown in Figure 1, when a conventional dot matrix printer prints the full-width character ``kan'' and the full-width character ``ji'', the number of dots that make up the blank area between these two-width characters is 6 dots. do.

On the other hand, when printing the half-width character "1" and the half-width character "2", the number of dots forming the blank area between these half-width characters is three.

When a dot matrix printer prints half-width characters horizontally, the number of dots forming the blank areas between half-width characters is half the number of dots forming the blank areas between full-width characters.

Therefore, the number of dots in the blank area between full-width and half-width characters is distributed appropriately, and even if full-width and half-width characters are mixed, a harmonious character arrangement can be obtained. It is something.

[Problems with background technology]

However, with conventional dot matrix printers,
In order to make the number of dots forming the blank area between half-width characters half the number of dots forming the blank area between full-width characters, the number of dots forming the blank area between full-width characters is printed as an even number. .

Therefore, if the number of dots that make up the blank area between full-width characters is an even number, it is not possible to increase or decrease the number of dots that make up the blank area between characters by one dot, for example, due to prohibition processing. .

If the even-numbered dots are increased or decreased by one dot and the number of dots that make up the blank area between full-width characters becomes an odd number, it cannot be divided into two, and the number of dots that make up the blank area between half-width characters is It becomes impossible to specify.

(Object of the Invention) An object of the present invention is to appropriately arrange dots even if the number of dots forming the blank part between full-width characters is an odd number when a dot matrix printer prints a blank part between full-width characters. All equipment is provided.

[Summary of the invention]

In order to achieve this object, the present invention newly provides a blank dot designation section, thereby dividing the odd dot 14, which constitutes the blank section between full-width characters, into even dots and odd dots.

Next, specify the number of trites constituting the blank part between full-width characters using these even number dots and odd number dots),
This makes it possible to appropriately allocate the number of blank dots.

[Embodiments of the invention]

In the embodiment of the present invention, as shown in FIG.
), character pattern buffer completion (2), character pattern generation section (3), blank pattern generation section (4), and blank dot designation section (5).

Here, the CPU (1) in the figure executes a program stored in the form of firmware in a ROM (6,) possessed by a blank dot specifying unit (5), which will be described later. It transmits and receives signals from each part and also controls each part.

3- The character pattern buffer (2) contains the character pattern generation section (
3) temporarily holds the full-width character patterns, half-width character patterns, and other pattern data output.

The character pattern generation part (3) is a character pattern buffer (
2), and outputs various pattern data to the blank dot indicating section (5), and provides information as to whether the generated pattern is a full-width character pattern or a half-width character pattern.

The blank pattern generating section (4) generates dots forming between character patterns under the control of the blank dot specifying section (5).

The blank dot instruction section (5) is, for example, l't OM.
It has firmware stored in (6) that performs the operations shown in FIG.

Also, when this firmware is executed by the CPU (1), it creates a predetermined number of blank dots, decodes signals specifying full-width and half-width character patterns from the character pattern generator (3), and processes the blank pattern generator. (
In step 4), a predetermined number of dots is specified.

Next, in the flowchart of FIG. 3, it becomes 6 start.

That is, the operation of the printer is started.

The next step is to set the number of blank dots (2N).
is executed. That is, the CPU (1) sets the number of blank dots forming the pattern between two full-width characters.

The next step is a 6 double-byte character pattern? "is executed. If YES" is selected here, the CP
U (1) specifies an address to the character pattern generation section (3) and instructs the transfer of double-byte character pattern data. The full-width character pattern data is transferred to the character pattern buffer (2).

In the next step, 6 blank dots = N'' is executed. That is, the CPU (1) creates a blank section based on the conditions that the set number of blank dots and the double-byte character pattern are specified. If it is determined that it is possible to create a blank section, the CPU (1) instructs the blank pattern generating section (4) to generate a blank pattern consisting of an even number of dots.Blank Based on this instruction, the pattern generator (4) generates blank pattern data consisting of an even number of inter-pattern dots.The blank pattern data is transferred to the character pattern buffer (2).

This completes the operation for the double-byte character pattern.

Further, in the above-described step "Full-width character pattern?", if 'NO' is selected and a half-width character pattern is designated, this designation information is output to the character pattern generating section (3).

In the next step, "N=even number?" is executed.

That is, if 'YES' is selected in this judgment, the number of blank dots (N) will be an even number. That is, C
PU(1) specifies a blank portion consisting of an even number of dots between p character patterns.

In the next step, "number of blank dots=N4" is executed. That is, the number of dots of the half-width character pattern corresponding to the even number of blank dots is obtained by CP'U(1). For this purpose, the plankton generator (4)
A blank pattern generation signal with half the number of dots as in the case of a full-width character pattern is given to . A blank pattern generating section (4) generates blank pattern data consisting of half the number of dots as in the case of a full-width character pattern. This blank pattern generation part C, character pattern buffer (2)
will be forwarded to.

This completes the operation for a half-width character pattern and an even character spacing pattern.

Further, in the step "N-Even number?", "No" is selected.In other words, when the number N of blank dots is an odd number, the blank pattern generating section (4) is selected by the CPU (1). The generation of a blank section consisting of an odd number of inter-pattern dots is instructed.

In the next step, is the number of blank dots between one character = even number? ”
is executed. If the judgment is “YES” here, the CP
U(1) determines the position of a blank portion connected to a half-width character pattern.

For example, the position of this blank part is "number cut" and "
3", the CPU (1) checks whether the blank part between the half-width character patterns, that is, the blank part located between the numbers 7-"2" and "3" in Figure 4, is in the specified position. will be judged.

Next, based on this judgment, in order to make the odd number of blank dots between character patterns an even number, the CPU (1) sets the number of blank dots between full-width character patterns smaller by 61".Furthermore, This number of dots is halved by the CPU (1), and this information is transferred to the blank pattern generator (4).
4) generates a blank pattern consisting of an even number of dots. This blank pattern i is transferred to the character pattern buffer (2) by the CPU (1). This completes the operation when a half-width character pattern is specified and the number of dots between double-width character patterns is odd.

Also, if the judgment in the above step is "NO", C, PU (
1), the position of the blank portion between the half-width character patterns is determined. In other words, the numbers "3" and "4" in Figure 4
It is determined whether the blank portion located in between is at a predetermined position.

Next, based on this judgment, in order to make the number of blank dots between the odd character patterns 8 and 8 even, the CPU (1) prints blank dots of the full-width character pattern e H"1"
It is set large. Furthermore, this number of dots is halved by CPU (1). This information is also transferred to the blank pattern generator 8 (S (4)). The blank pattern generator (4) generates a blank pattern consisting of an even number of dots. This blank pattern is used as a blank pattern by the QPU (1). The data is transferred to the pattern buffer (2).This completes the operation when a half-width character pattern is specified and the number of dots forming between the full-width character patterns is an odd number.

〔Effect of the invention〕

The effect of the present invention is that the number of dots constituting the blank section is set in units of two dots in the conventional art, but the number of dots can be set in even or odd numbers.

Therefore, in the prohibition process when a comma is placed at the beginning of a line, it is possible to properly arrange the character pattern.
