Abstract

PURPOSE:To speedily print dots in a high density, by moving a ribbon synchronously with printing timing at a predetermined angle against the moving direction of a printing paper. CONSTITUTION:The ribbon 3A is moved in a direction inclined at a predetermined angle a row of printing pins 4, and is fed in the direction of an arrow R with the moving timing substantially coinciding the printing timing of the pins 4. Accordingly, the ribbon 3A can be sequentially and continuously fed out at the printing timing of the pins 4, the feed quantity can be accurately controlled, and printing speed can be enhanced.

Description

[Detailed description of the invention] The present invention relates to a printing method for a dot printer device.

A printer device is one of the output devices in a computer, and prints the contents stored in a memory on paper and outputs it as data. Therefore, it is effective when saving programs and program execution results in a visible form. Also, dot printer devices are widely used as this printer device.

This dot splitter device has a configuration in which, for example, each pin arranged in 9 columns and 7 rows is electrically driven, and some of these pins are selectively driven by a solenoid to print on a piece of paper. It is possible to display one character or figure by a collection of dots printed on the dots through a ribbon, and by arranging these units in parallel, it is possible to display a large number of characters and figures. It has become.

In addition, as another conventional example, nine printing pins per character are set as one unit, and by arranging these units in the same row and driving these pins and paper at a fixed timing, one line is printed on the primary paper. A printing method is also provided in which a character with a repeating number of digits is formed and this is repeated on the second and subsequent lines.

FIG. 1 is an explanatory diagram showing this conventional printing method. In the figure, (1) shows the paper moving in the direction of arrow P on the platen (2) at a constant timing, and (3) shows the paper moving on the platen (2).
The Zuro Ribbon moves upward at a constant timing in the direction of arrow Q - (
Reference numeral 4) denotes printing pins arranged in series in the traveling direction on the ribbon (3), with nine pins per character, which are driven by a solenoid or pressure element.

In such a conventional printing section structure, nine printing pins (4) are selectively driven to form - characters;
The driving of this printing pin (4) and the feeding of the paper (11) are synchronized, and one letter is formed on the paper in the next Te, and the next letter is formed by the printing operation by the other nine printing pins. The characters on the first line are shaped.

Next, after printing of the -th line is completed, 1 paper + 11 is, for example, the character -
At the same time, the ribbon (3) is fed by an amount corresponding to the width of the - line, and then the printing of the characters in the che line is repeated in the same manner.

However, in such a printing section structure.

- Each time a line of characters is formed, the ribbon (3) must be quickly fed by the width of the - line, and the accuracy of the feed must be precisely controlled and the feeding time must be accelerated. There were technical limitations.

In addition, the width of the ribbon (3) is constant, so the size and number of printing pins that can form one character are determined within this width, making it impossible to increase the density of dots or select the character size. It was an inconvenience.

Furthermore, there was a problem that the usage efficiency per unit length of the ribbon (3) was poor.

The present invention aims to solve such conventional problems, and by running the ribbon at a certain time in the moving direction of the paper to be printed in accordance with the printing timing, high-density dots can be produced. The present invention provides a printing method for a dot printer that allows printing to be performed quickly and improves the usage efficiency per unit length of ribbon.

An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 12 is a schematic explanatory diagram of the printer 1 to the main parts of the printer apparatus, but does not show the printing method of the present invention. Note that the same components as those shown in FIG. 1 are designated by the same reference numerals. In Figure 2, + (3A) is a ribbon, and this ribbon (3A)
The printing pins (4) run at a constant angle in the direction of peeling off the ends of the printing pins (4) arranged in a row.

Further, the running timing of this ribbon (3A) substantially coincides with the printing timing of the printing pin (4), and it is continuously fed from bottom to top in the direction of arrow R at a constant speed.

With this fundamental configuration, the ribbon (3A) can be continuously fed out 1111 times at the printing timing of the printing pin (4), and the feeding amount can be accurately controlled - and the feeding time can be further increased. In other words, a printing luck shop.
can be done faster than before.

In addition, by adjusting the feed speed of the ribbon (3A), it is possible to narrow the gap between each printing dot in the vertical and horizontal directions, and it is possible to increase the density of the characters represented by each dot. That is, the number of dots per character is not limited by the size of the printing pin, making it possible to display each character more clearly.

Furthermore, the number of prints per unit length of the ribbon (3A) can be increased compared to the conventional case, and the efficiency of using the ribbon (3A) can also be improved.

According to one aspect of the present invention, as described in detail above.

- By tilting the ribbon at a certain angle to the rows of printing pins and running it at a certain printing timing, it is possible to quickly perform high-density dot printing. be.
