Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing method for a serial printer equipped with a type matrix, and in particular, the present invention relates to a printing method for a serial printer equipped with a type matrix, and in particular, to print characters, numbers, etc.
It concerns a method of printing symbols.

Generally, in a serial printer equipped with a type matrix, the type body 1 attached to the print head is placed on a type stand 2 (hereinafter referred to as standard type stand) of a size corresponding to the spacing of the print head, as shown in Fig. 1. )
3 (hereinafter referred to as standard character zura) of approximately the same size are provided. Note that this typeface 1 is referred to as a standard typeface.

On the other hand, this standard character zura 4 is smaller than the character 3.
(hereinafter referred to as reduced typeface) is provided on the standard type stand 2 as shown in Fig. 2 (hereinafter referred to as reduced typeface 5).
) has the disadvantage that the spaces between the printed characters are too wide.

Also, in Utility Model Application Publication No. 12711 of 1930, the left edge of each character is shown aligned with the reference line. However, since the character width is not constant, it is difficult to print within a predetermined range.

Therefore, a type body (for example, N=3
The case is shown in FIG. 3, and the typeface is called a combined typeface 6. ) has been proposed.

Next, a case where printing is performed using this combination typeface 6 as shown in FIG. 4 will be described. First, the standard typeface 1 is printed at the spacing position S ₁ , then the standard typeface 1 is printed at the spacing position _S2 , and then the combination typeface 6 is printed at the spacing position _S3 , Next, standard typeface 1 is printed at spacing position _S4 .

However, the combination typeface 6 shown in FIG.
Since the combination of letters ``V'' is fixed, there are many types of combination type 6 to create an arbitrary combination, and the type cannot be accommodated in the print head. Moreover, it had the disadvantage that it was difficult to manage the typeface.

Therefore, the standard type plate 2 is divided vertically into N equal parts, and one of the N×N parts formed by vertically dividing into N equal parts is provided with reduced character zura 4. ) has been proposed. For example, N=3
In this case, divided typefaces 7a to 7c shown in FIGS. 5a to 5c are provided.

Next, the case of printing as shown in FIG. 4 using these types of divided type bodies 7a to 7c will be described. First, standard typeface 1 with spacing position S ₁
is printed, then the standard typeface 1 is printed at the spacing position S ₂ , and then the divided typeface 7a shown in FIG. 5a is printed at the spacing position S ₃ , and the division shown in FIG. In addition to printing the typeface 7b, a divided typeface 7c shown in FIG. 5c is also printed. Next, standard typeface 1 is printed at spacing position _S4 .

However, even in the above configuration, three types of divided typefaces must be provided for each numeral, which has the disadvantage that the number of divided typefaces increases.

Therefore, the object of the present invention is to provide one type of divided typeface for each number by printing using one type of divided typeface of three types of divided typefaces, for example 7a, and to print this type of divided typeface for each number. Printing is performed with a spacing that is 1/N (in this case, N=3) of the spacing amount of the standard typeface.

Next, the operation of the printing method according to the present invention for printing the numeric string shown in FIG. 4 using the divided typeface 7b shown in FIG. 5b will be described with reference to FIG. 6.

First, standard typeface 1 is printed at spacing position S ₁ (see Figure 6b), then at spacing position S ₂
to print the standard typeface 1 (see Figure 6c), then print the divided typeface 7b at the spacing position _S3 (see Figure 6d), then print the standard typeface spacing amount (T ) with a backspace of 1/3 of the spacing (T/3) (see Figure 6e), then print the split typeface 7b with a spacing of 2T/3, in other words T/3. After performing the spacing twice, the divided typeface 7b is printed (see Fig. 6f).
), then standard typeface 1 at spacing position S ₄
(See Figure 6g).

Although the case where N=3 has been described above, the present invention is not limited to this, and it goes without saying that it can be done arbitrarily.

In addition, in the above embodiment, the case where printing is performed in the direction of the print line by the spacing operation of the print head has been explained, but according to the feed operation of paper feed, in other words, it is possible to relatively move the print head in the direction perpendicular to the print line. By pacing and performing the spacing amount of T/N in the vertical direction, it is also possible to print as shown in FIG. 7 in the same manner.

Further, in the above explanation, a specific number, in this case "2", was used, but it goes without saying that other numbers, letters, symbols, etc. can be used in the same way, or in combination.

It goes without saying that the printing method according to the present invention can be applied to the control of a serial printer equipped with a commonly used type matrix.

As described above in detail, according to the printing method according to the present invention, without increasing the number of divided typefaces,
Moreover, by setting the printing interval to an appropriate value, it is possible to print a plurality of characters, numbers, symbols, etc., which are difficult to reduce, within the width of a standard typeface. In particular, in order to compact the amount of information in a relatively small printing field of a predetermined size, such as a bank passbook, multiple reduced typefaces are mixed in with the standard typeface and are printed regularly without protruding from the printing field. It is effective when applied when required.

Claims (1)

[Claims] 1. In a printing method in which a type matrix is provided in the print head of a serial printer and reduced type is printed by adjusting the feeding amount of paper and the spacing amount of the print head, the standard of the spacing amount T Move the type plate vertically to N.
A divided typeface is constructed by dividing the typeface into equal parts and providing reduced letters in one part divided into N equal parts in the horizontal direction, and then spacing or back spacing the divided typeface by an integral multiple of T/N.
