Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an impact type serial printer.

(Prior art and problems to be solved by the invention) There are two types of conventional impact type serial printers: matrix type and dot matrix type. It has the advantage of being able to print with high quality, but it has the disadvantage of not being able to print graphics, etc.

Further, the dot matrix type has the advantage of being excellent in versatility for graphic printing, character printing, etc. However, since it is a pixel printing method, the printing quality of the characters is inferior to that of the Ifi type type.

A conventional technique to deal with these shortcomings was disclosed in Japanese Patent Application Laid-open No. 57
It is disclosed in Japanese Patent No.-12673.

The publication describes a serial printer that prints while moving a carrier V unit equipped with a matrix type head in the left-right direction along a platen, and a matrix provided on the π-plane side of the type head to strike the type head. It is equipped with a composite type hammer that integrates a mold type printing hammer and a dot type print head that directly hits the printing paper on the platen, and the matrix type printing hammer is driven to hit the back side of the type to print the matrix type type. A serial printer is disclosed in which dot matrix printing can be performed directly by driving the dot type print head, and the printing method is an ink ribbon type, and an example of the print head is a cup-shaped print head. A conventional and a daisy-wheel type are shown. According to the conventional example, as shown in the same publication, it is possible to print high-quality characters, which is a characteristic of the matrix type, and to display graphical shapes of graph caps, which are characteristics of the dot type, and to print characters that are not mounted on the matrix type head. Conventionally, two printers were required to print text and characters of any size, but now one printer can print the same output document, reducing the time it takes to create text and making it more economical. This has the effect that the installation area of the printer can also be reduced.

However, according to the conventional example, there is a v1 limit to the number of types that can be incorporated into the type head, and even if the type head were made replaceable, the type of type could be changed, but the number of types could not be increased, so the type head The drawback was that it was not possible to print multiple characters by just using the printer.

In addition, in the future, a greater number of colors will be required for graphic printing, image printing, etc., but the ink ribbon method has the disadvantage that it cannot increase the number of colors and cannot meet that demand. was there.

The present invention is aimed at eliminating the drawbacks of the prior art described above.

(Means for Solving the Problems and Effects of the Invention) The present invention provides a printer device as an output device of a computer system, etc., in which a print head has a print hammer for matrix type and a print wire array for dot matrix printing. We also have
One or several rows of ink-impregnated bodies and matrix type bodies are arranged on the platen, and one printer can print characters, etc. with extremely high quality as needed, as well as graphic printing, image printing, etc. FA' can be performed in multiple colors, and by replacing the ink-impregnated body with a matrix type body or vice versa, FA' with a larger number of types can be performed.
It has the effect of being able to print 8t characters and dot matrix printing with more than J2 colors.

(Example) The present invention will be described below with reference to Examples. In Figure 1,
The print head 1 is provided with a print hammer 2 for matrix type printing and a print wire array 3 for dot matrix printing.
The print head 1 is controlled to move along the printing paper 4 at right angles to the paper feeding direction, and matrix type printing or dot matrix printing is performed as described below.

A cylindrical platen 5 is disposed parallel to the printing direction of the printing hammer 2 and the printing wire row 3, and the outer periphery of the platen 5 is arranged in a plurality of pieces, in this example eight pieces, along the longitudinal direction of the platen. One of the parts, 1WA, is the ink-impregnated body 6 or the matrix type body 7.

The ink-impregnated body 6 consists of a porous body 6a and its reinforcing plate 6b, as shown in FIG. 4, and the porous body 6a is impregnated with ink. As shown in FIG. 3, the matrix type body 7 is composed of a matrix type part 7a and a reinforcing plate 7b, and a plurality of lines of type are protruded from the matrix type part 7a along the longitudinal direction.

In the ink-impregnated body 6 and the matrix type body 7, the shapes and dimensions of the reinforcing plates 6b and 7b, which are attached to the platen body 8, are equal to each other.

The ink-impregnated bodies 6 and the matrix type bodies 7 are detachably attached to the platen body 8, and the ink-impregnated bodies 6 with different colors and the matrix type bodies 7 with different types of characters are each pre-installed in plural numbers. They can be prepared in advance and can be freely replaced and attached to the platen main body 8 as needed.

That is, the ink-impregnated body 6 and the matrix type body 7 disposed on the platen body 8 are respectively connected to other ink-impregnated bodies 6 in this order.
Alternatively, it is possible to replace the matrix type body 7 and the ink-impregnated body 6 or the matrix type body 7 of the pond, thereby attaching the ink-impregnated body 6 and the matrix type body 7 of a certain standard number and hardness. With the platen 5, it is possible to print characters, etc. with extremely high quality with a single printer, as well as to print figures, images, etc. in multiple colors.Furthermore, depending on the application, the ink-impregnated body 6 can be used as a matrix type. 7 or vice versa, it is possible to perform complex character printing using a larger number of printed characters, etc., or to perform dot matrix printing using a larger number of colors.

The platen main body 8 is rotatably and slidably fitted onto the platen shaft 9, and is further rotatably supported by the platen support 1o. The platen body 8 further includes a platen gear 11.
are fixed, the platen gear 11 meshes with the square shaft gear 12, and the square shaft gear 12 is slidably fitted on the square shaft 13.

Therefore, the platen main body 8 is driven from a drive source (not shown) in the rotational direction to the square shaft 13, the square shaft teeth 1f12, and the platen gear 1.
1, and positioning in the rotational direction is performed. Further, a wire 16 is fixed to the platen support 10 by a wire clamp 14 and a screw 15, and is moved via the wire 16 from a drive source (not shown) in the traverse direction of the platen to move the platen body 8. Positioning in the traverse direction is performed. In this way, the position of the platen main body 8 in the rotational direction and the traverse direction is controlled, and the printing hammer 2
And an arbitrary relative position with respect to the printing wire row 3 is set.

When printing using the dot matrix type printing wire row 3, the platen body 8 has a plurality of ink-impregnated bodies 6 facing the printing wire row 3, and a plurality of ink-impregnated bodies 6 with different ink colors are selected by rotating. By selectively striking the plurality of printing wires in the printing wire row 3,
Color printing can be performed using a dot matrix on the printing paper surface on the platen side.

Furthermore, even in one ink-impregnated body 6, one ink is caused to have a displacement of several lines due to rotation, and also to have a lateral displacement in relation to the head due to differential movement in the traverse direction of the head in the traverse direction. By striking the impregnated body 6 uniformly, the durability life of the ink-impregnated body 6 can be greatly extended.

Further, when printing with the printing hammer 2 in the form of a matrix type, the platen main body 8 places the matrix type body 7 facing the printing hammer 2, and the ink ribbon 17 connects the printing paper 4 and the matrix from a position where it does not interfere with printing. Move between typefaces 7. As described above, as shown in FIG. 3, the matrix type body 7 has a number of rows in the rotational direction and a plurality of columns in the cross-feeding direction, and the platen main body 8 The lateral feed direction is controlled by each driving source, and the desired characters on the matrix type body 7 are controlled to face the print head 1, and the ink is attached to the printing paper surface on the ink ribbon side by hitting with the printing hammer 2. , printing is performed using matrix type.

Needless to say, when switching to dot matrix printing again, the ink ribbon 17 is moved to a position where it does not interfere with printing.

<Effects> As described above, the present invention provides a printer device as an output device of a computer system, etc., in which the print head is provided with a print hammer for matrix type and a print wire row for dot matrix printing, and one or more print wires are installed on the platen. It is equipped with multiple ink-impregnated bodies and matrix type bodies, and allows a single printer to print characters, etc. with extremely high quality as required, as well as to print figures, images, etc. in multiple colors. Furthermore, by replacing the ink-impregnated body with a matrix typeface or vice versa, it is possible to print 1 to F characters using a larger number of typefaces, etc., or to print a larger number of colors. There are remarkable effects such as the ability to perform dot matrix printing.
