Abstract

PURPOSE:To enable clear printing to be executed by improving a slant line part and a curved line part, by making each dot a tetragon composed of several pieces of triangular points. CONSTITUTION:Each tetragonal dot is composed of four pieces (capable at arbitrary number of pieces) of triangular points of (a), (b), (c) and (d) in a structure drawing of a dot installed at the printing head of a printer. In the printing head, eight pieces (may be arbitrary number of pieces) of dots are vertically lined and two lines thereof are regularly arranged. By storing a character represented by collecting basic triangular points in ROM inside the printer, a sentence inputted by a keyboard is heated at each triangular point of (a), (b), (c) and (d) of each dot having a heating element by a command of printing, printed with ink by moving the surface of paper while fusing the ink of a ribbon and otherwise, can be printed on the heat sensitive paper being discolored by heat.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printer for printing on word processors, personal computers, computers, and the like.

(1) Prior art Each dot in the print head of conventional printers such as word processors and personal computers is almost square in shape, and since Japanese kanji have a large number of strokes, they are generally 24 or 32 dots. It is used.

In this way, since a square is used as the basic minimum dot, the shaded area becomes a mosaic, and the 24x2
Since it uses 4 dots, it has the disadvantage that printing time is slow.

(2) Purpose of the Invention The present invention relates to a dot matrix type printer, and in order to eliminate the drawbacks of the conventional printer, each dot is made into a rectangular shape composed of several triangular points.
It is an object of the present invention to provide a printer in which the oblique lines and curved parts are also significantly improved, and the printing is as beautiful as printed characters.

(3) Structure of the Invention An embodiment of the printer of the invention will be described below with reference to the drawings.

The first illustration is a configuration diagram of the dots installed in the print head of the printer of this invention, and each rectangular dot has albSC.
It is composed of four triangular points (which can be any number) of s and d.

As shown in FIG. 2, the print head of the present invention arranges eight dots (any number may be used) in a column and correctly arranges them in two rows.

Characters expressed by a collection of triangular points, which is the basis of this invention, are stored in the ROM inside the printer, and text entered using the keyboard is printed by one of each dot with a heating element according to the printing command. It is possible to print with ink by heating each triangular point (b, c, d) and moving it across the surface of the paper while melting the ink on the ribbon, or to print on thermal paper that changes color due to heat.

In conventional printers where the minimum ridge dot is a rectangle, the dots are a collection of rectangles, so diagonal lines and rounded parts of the characters become mosaic-like, and even if the number of dots is increased, the print quality is significantly inferior to that of printed type, making it difficult to print. Some places do not accept dot-printed documents such as word processors.

In this way, since each dot in a conventional word processor is a rectangle, it can only be stacked accurately in the 90 degree direction, so only the vertical and horizontal directions are correct. Most of the letters such as Roman letters are made up of diagonal lines and curved parts, so it is impossible to use a square as the basic minimum dot.

In order to eliminate the disadvantage of the unique mosaic-like font of conventional word processor fonts, this invention made one dot into a quadrilateral made up of four diagonal points, and each basic triangular point had a single heating element. When printing is performed, the heating part of the dot is either triangular or square according to the font stored in the ROM.

3A and 3B are conventional 16-dot printing using square dots, and the diagonally shaded portions of both hiragana and kanji characters form a mosaic pattern, making them disqualified as printing.

Figures 4A and 4B are 16 x 16 dots printed with rectangular dots made up of several triangular points according to the present invention, but even when enlarged in this way, they are hardly distinguishable from printed letters. It's an excellent font.

As mentioned above, this font has 16 tots and more than 24 tots.
．． The font would be even better if it were set to 32 dots, but this level seems to be sufficient for general documents.

If the font has 16 dots in this way, the printing time will be reduced to less than half that of the conventional 24-dot font, and the manufacturing cost will also be reduced, making it economical.

Figure 5 shows the printing of each kanji font composed of triangular points and squares according to the present invention. , No. 5 is cursive, and even when enlarged in this way, it has an elaborate and beautiful font, so if the font is the same, it would be difficult to distinguish it from printed text.

Like kanji and kana, numbers in Roman letters are so beautiful that they are indistinguishable from printed letters.

Furthermore, the use of square dots made up of several triangular points with different angles would be effective not only for printing but also for drawing.

(4) Effects of the Invention Since each dot, which is the basis of conventional printers such as word processors and personal computers, is square, there is a serious drawback that no matter how many dots are increased, the diagonally shaded portions of characters become mosaic-like.

This invention solved this problem by forming square dots made up of several basic triangular points, and not only vertical and horizontal lines, but also diagonal lines and curved parts are so elaborate that they are indistinguishable from type. It has an excellent advantage of being able to produce beautiful printing. Furthermore, any foreign language can be printed in a beautiful font with 16 dots.

In this way, the printer of this invention has a beautiful font even with 16 x 16 dots, so it can be used in the same way as typeface, and the printing speed is dramatically improved compared to the conventional 24 x 24 dots, reducing the printing time to half. In addition to being able to shorten the process to the following, manufacturing of the printer is also simplified, resulting in lower costs.

The printer of this invention can be used for all printing printers such as word processors, personal computers, and computers.
