Abstract

PURPOSE:To make it possible to increase a printing speed, in the printer of a personal computer, by performing the printing of one line in a state divided into two stages at every plural dots by printing heads laterally arranged in a double line. CONSTITUTION:A plurality of lines of printing heads 16..., 17... are laterally provided to a head carriage 15 in a double line in parallel in opposed relation to a platen 11 so as to provide equal intervals S therebetween in a printing line direction and a predetermined printing line interval (l) between the printing head lines. At first, a plurality dots of the characters of one line are printed by the pins 161 of the front stage printing heads 16... in a paper feed direction and, subsequently, paper A is fed and the residual dots are printed by the pins 171 of the rear stage printing heads 17... and, by this method, the characters or figures of one line are printed by the printing heads 16..., 17... arranged in a double line and a printing speed can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a printer used as an output device for a personal computer or the like.

BACKGROUND ART Printers used as output devices for personal computers, etc. have a paper feed mechanism that winds paper onto a platen, supplies and ejects the paper, and a head carriage equipped with a print head section that rotates in the paper feed direction. A drive mechanism and the like that reciprocate with a constant stroke in the direction of the orthogonal rotation axis of the platen are provided with an extra force of 11''.

The print head unit is installed close to the platen, and the print head unit prints on the paper wrapped around the platen via an ink ribbon or the like by S blowing. In this type of printer, the head carriage is moved in the printing line direction. The printing head is reciprocated multiple times with a constant stroke, the paper is fed each time the head carriage moves forward and backward, and one line of printing is performed by reciprocating the print head several times each time the head carriage moves back and forth.

However, in the conventional line printer, the print head is arranged in a horizontal line along the print line, and the print head is arranged horizontally in the horizontal direction f.
Since the structure is such that one digit is printed during several restorations,
There is a limit to the printing speed, and it has been difficult to increase the processing speed beyond that.

The present invention has been developed to solve the above problems, and its purpose is to increase the printing speed of a printer and improve the printing processing efficiency.

In order to achieve an object more than a means for solving the problem, in the present invention, the print heads provided on the head carriage along the print line are arranged in a row at predetermined intervals in the paper feeding direction. They were arranged side by side and configured to print one digit with two rows of print heads.

Function: In the method of the present invention, first, the print head at the front stage in the paper feed direction prints a double image of one line of characters, and
Then, at t* when the paper is not fed, the remaining dots are printed by the print head in the latter stage', and at this time, one digit is printed. Therefore, − digits of characters.

Graphics, etc. are arranged in two rows and printed by the print head, resulting in high printing speed.

EXAMPLES Below, 11 examples of the fruits of this invention will be explained in detail with reference to the drawings. −.

Figures 1 and 2 show a printer using the method VC) of the present invention, in which A indicates paper.

The printer is provided with a horizontal rotation shaft 10, and this rotation i11+1. Platen] 1 is attached to O.

Paper A is wound around this platen] and the paper is fed as the platen 11 rotates.The feeding section and discharge section of the paper A to platen 1 are equipped with a Bren Yarrow that is in pressure contact with the platen]]VC. ]2.12 is provided.By this pressure roller 12°12, the paper A
The paper contacts the platen 11 and is fed without slack.

On the other hand, two guide shafts 1.
3.14 is arranged and this guide/gift 1.3,1.
4 [The head carriage 15 is slidably mounted. Head carriage 15, Guiden Yahu 1-13.1
．． 4, it is moved back and forth with a constant stroke in the printing line direction perpendicular to the paper feeding direction.

On the head carriage 15, facing the platen 11,
A plurality of print heads 16°..., 17 at regular intervals
．． ... has been established. Print head 16°16,
......and 17, 17. . . . are provided on the same number sides at equal intervals S in the print line direction, and are provided in parallel and in two horizontal rows at a predetermined print line interval t. Head pins 161 and 171 are provided to protrude from one surface facing the platen 11. Then, the head pins 161 and 171 are applied to the paper A wrapped around the platen 11 from above the ink ribbon (not shown) supplied between the print head 16, 17 and the platen 11, thereby printing. will be held.

In the embodiments of the present invention, a 71J action feed method using a brain roller is illustrated and explained as the paper feeding method for the paper A, but other pin feed and tractor feed methods are also applicable. good.

Next, a printing method of the present invention using the printer configured as described above will be explained.

Printing of characters, figures, etc. is represented by a collection of dots on paper A of head pins 1.6], . . . 1.71 by striking the print head 16, 1.7.

This is performed by reciprocating the head carriage 15 with a constant stroke for one inch, and feeding the paper A stepwise in the paper feeding direction each time the head carriage 15 moves forward and swings.

First, the above-mentioned head carriage 1
5 reciprocates multiple times. As a result, as shown in FIG. Multiple dots indicated by are printed. Next, paper A is fed with a stroke twice the vertical width N of the character (A...), and the character (A...) is printed on the subsequent print head 16... It is made to correspond to... Next, the remaining dots except for the company number dots printed by the print heads 17 are printed by the printing interval I of the print heads 16. In this way, printing of characters for the - line is performed as shown in FIG. At this time, a plurality of dots out of all the dots constituting the second line of characters (B...
It will be held at 7...

In this way, along with the paper feed operation, the second line.

The third line... and so on are printed one after the other.

As described in detail, according to the printing method according to the present invention, -
Since the printing for a row is done in two rows of multiple dots by the print heads arranged in two horizontal rows, compared to the conventional method in which all the dots of one code are printed by the print heads in the - column,
The printing speed can be made faster, and the processing efficiency of output to the printer is increased.
