Abstract

PURPOSE:To perform the printing treatment of a form overlay pattern such as a rule within a short time, by constituting the titled printer so that the dot position length of a printing head is made at least same to the width of a printing line. CONSTITUTION:In a printing head 10, the dot position length thereof is made larger than the size C of a character and made same to the size of a new line pitch L. Therefore, when a rule is drawn, a line L1 is at first printed at time t1 and, subsequently, a new line is started as usual to print a line L'2 at time t2, a rule L0 can be printed. When a usual character is printed, for example, ''0'' is printed to each pin of the printing head 10 corresponding to the difference of the size C of the character and the new line pitch L, that is, positions (d, d) to impart ''0'' fixedly so as not to type a printing pattern. By this method, a form overlay pattern, for example, a rule over a plurality lines can be simply typed within a short time.

Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a serial dot printer, and particularly to one suitable for printing Form Overlay II patterns such as ruled lines in a short time.

Prior Art and Problems Conventionally, when printing is performed using a serial dot printer, the standard line feed pitch of the printer is approximately 0.423 m (-!- inch). In this case, the size of the print radius of the printer is set smaller than this line feed pitch. That is, as shown in FIG. 1, when the line feed pitch is L, the size C of the character printed on this is smaller than the line feed pitch L, so when printing this character, the print head 1 of the printer The dot position length is also limited to the size of C. Note that the dot position length here refers to the print head 1.
The top pin P at. This refers to the distance between the bottom bin PIl and the bottom bin PIl in the printed state. Therefore, when printing characters using this print head 1, it is possible to print characters with a distance of 9 characters 1 between each line.

By the way, when using such a print head 1 to print a pattern in which characters are mixed with a form overlay pattern such as a ruled line, it is necessary to print a line in the 1 character interval area in order to print the ruled line. This requires special printing and line feed control.

That is, conventionally, ruled lines as shown in FIG. 2(a),
When launching a ball, it was necessary to perform the following control. First, time 1 in Figure 2 (b). , print head 1
The line L1 is printed by. The length of this line L1 is C. Next, at time t2, the print head 1 is turned on at 0423 x-! −
(-!-inch) Line break and type short line L2 12. This line L2 has a length equal to the character interval l so that the L1 portion and the printed portion are not automatically shipped and are continuous. Then, move the print head 1 again by 0.423Nx (-!-inch), and print a 0.421m line feed for the first 12 lines L1. In this way, multiple lines of continuous ruled lines as shown in FIG. 2(a) are created. will be launched.

However, in this case, as mentioned above, special printing and line feed control are required to draw the short line L2 between lines L1 and L3, so it takes a long time to create the ruled line LO, and the control is complicated. There is a problem of becoming.

OBJECTS OF THE INVENTION The purpose of the present invention is to solve these problems, ie, when printing a form overlay pattern such as a ruled line, special printing and line feed control are required to print even in one part of the character interval. It is an object of the present invention to provide a serial dot printer in which printing takes time and control is complicated.

SUMMARY OF THE INVENTION To accomplish this object, the present invention provides a serial dot printer having a print head with a plurality of print dots.

It is characterized in that the dot position length of the print head is configured to be at least the same as the width of the print line.

Examples of the invention An embodiment of the present invention will be described based on FIG.

In FIG. 3, the dot position length of the print head 10 is made larger than the character size C and the same size as the line feed pitch L. Therefore, when drawing ruled lines,
As shown in , first, the line L'□ is printed at time t1, and then a line feed of 0.425 vm is performed as usual, and the line is printed at time t2.
If the line L'2 is printed in this manner, the ruled line Lo can be printed as shown in FIG. 6(d). Therefore, there is no need to perform special printing or line feed control when printing ruled lines, and printing can be performed very easily and quickly.

In addition, when printing normal characters with the print head 10 shown in FIG. 3(b), the difference between the size C of the two characters and the line feed pitch L, that is, the digit 1ff in FIG. 3(a), is
f1. For example, "0" may be applied to each bin of the print head 10 corresponding to d and d, and "0" may be fixedly assigned so as not to print a print pattern.

In the embodiment shown in FIG. 3, the dot position length of the print head is described as being the same as the width of the print line, that is, the line feed pitch, but it may of course be made larger than the line feed pitch. In this case 2, for example, if the configuration is such that the lower part is located in the next row.

For example, like cursive letters g and y, there is a partial division on the next line. In other words, even large characters or symbols on a portion of the descender can be easily printed.

In the above explanation, an example of a form overlay, pattern color, and ruled line has been explained, but of course, the present invention is not limited to this, and graphs and pictures can also be printed efficiently in the same manner. The print head is an inkjet type.

It can be applied to various types such as wire tod type and thermal dot type.

Effects of the Invention According to the present invention, when printing a form overlay pattern such as a ruled line that spans a plurality of rows, it is possible to print the pattern very easily and continuously.

There is no need for special printing and line feed control for pattern printing in character gap areas as in the past, and therefore such a pattern can be printed easily and in a short time.
