Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a printing device capable of printing by type and by dot matrix.

BACKGROUND TECHNOLOGY In general, type printing has the characteristic of being able to print clearly, but has the disadvantage of being slow in printing speed, and dot matrix printing has the characteristic of being fast in printing speed. On the other hand, there was a drawback that the printing was unclear.

In response to this situation, printing devices equipped with two printing sections that perform double-sided printing have been proposed.

However, in this conventional device, the two printing sections are selectively moved and arranged as needed to one printing position corresponding to the printing line on the platen, and printing is performed on either of the two printing sections. After performing the above, the two printing sections were selectively attached/detachable and replaced directly on the 4th printing line corresponding to the printing line on the platen, and printing was performed using either one of the printing sections. Because of this, it is very troublesome to selectively move and arrange the two printing units for one printing position or to attach and detach them, and it is very troublesome to print letters and dots at different positions on a single sheet of printing paper. It was not possible to perform printing selectively with matrix printing.

Purpose of the Invention This invention eliminates the above-mentioned defects, and eliminates the need for troublesome operations such as attaching, detaching, and replacing two printing units by selectively moving and arranging them to printing positions. When printing a table on a paper, printing can be done using movable type at different positions on a single sheet of printing paper, such as printing the frame line of the dragon using a dot matrix and printing the characters within the frame line using foil. To provide a printing device capable of selectively performing dot matrix printing at will, fully utilizing the characteristics of a split printing part, and performing clear printing at high speed.

A further object of the present invention is to provide a printing device which can be extremely simplified in construction by requiring only one printing ribbon shared by both printing parts.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a printing device having a carrier that reciprocates along printing lines on a platen. a first printing section that performs a printing operation by hitting the surface of the printing section with a hammer;
A second printing section that is supported on the carrier so that the printing point is a predetermined number of characters above or below the printing point of the printing section, and is located between the second printing section that prints in a dot matrix and the double printing section double platen. and a ribbon actuating section having a printing ribbon that is selectively shifted to each printing point of the split printing section.

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

Now, the frame of the printing device of this embodiment (not shown)
A platen 1 having a circular cross section is rotatably supported on the platen 1, and a guide rod 2 is installed parallel to the platen 1. A carrier 6 is movably supported by the guide rod 2 and is reciprocated along the printing lines on the platen 1. First and second printing units 4 and 5 having different printing points are supported on the carrier 6.

The first printing section 4 includes a petal-shaped type dinuk 7 having a large number of type parts 6 on the surface facing the platen 1, and a selected type part 6 by rotating the type disk 7 to print the selected character part 6 on the printing line of the platen 1. A selection motor 8 and a hammer 9 are provided, which are arranged to correspond to the selection motor 8 and a hammer 9 which strikes the back side of the selected type part 6 to print on the printing paper on the platen 1. Further, the second printing section 5 is provided with a print head 10 that prints on the printing paper in a dot matrix based on the selection operation of a plurality of printing pins (not shown).

In this embodiment, the second printing section 5 is arranged so that its printing point is a predetermined number of characters above (on the printing paper feeding side) from the printing point of the first printing section 4. .

As shown in FIG. 2, a Haribon cassette 11 is removably supported on the frame so as to correspond to the entire moving range of the carrier 5, and a part of the printing ribbon 12 made of an endless fabric ribbon is attached to the frame. Platen 1
It extends to the outside of the ribbon cassette 11 at the side. At both ends of the platen 1, ribbon actuating members 13 as ribbon actuating parts are rotatably supported around the rotational axis of the platen 1, and the extending portion of the printing ribbon 12 is stretched between the front ends thereof. The print section 4.5 is positioned between the split printing section 4.5 and the platen 1.

Solenoids 14 are disposed on the frame corresponding to both ribbon actuating members 15, and their plungers 15 are connected to the ribbon actuating members 16 via wires 16, respectively. During the printing operation of each printing section 4, 5, the ribbon actuating member 13 is rotated by the operation of this solenoid 14, and the extending portion of the printing ribbon 12 is moved to the printing point of the first or second printing section 4.5. It is designed to be selectively shifted to .

Therefore, in the printing apparatus of this embodiment, when the printing paper is inserted onto the platen 1, the first and second printing sections 4.5
When a printing signal is selectively input to the printer, the solenoid 14 is activated and the ribbon actuating member 16 is rotated to shift the printing ribbon 12 to the printing point of the selected printing section 4 or 5. , both the printing parts 4.5 are operated optionally, and printing by the printing part 6 or the dot matrix is carried out in appropriate combinations at different printing points on the printing paper.

Therefore, when printing tables, etc., frame lines are printed using dot matrix,
Characters within the frame lines can be divided as in the type part 6 and can be printed clearly and at high speed.

Note that the present invention is not limited to the configuration of the embodiment described above; for example, the printing ribbon 12 is inserted into the ribbon cassette 11.
It is also possible to arbitrarily change the configuration of each part without departing from the spirit of the present invention, such as configuring the print point to be selectively shifted to the printing point of both printed portions 4.5.

Effects of the Invention As detailed above, the present invention is capable of printing images on a single sheet of printing paper without requiring the troublesome operations of attaching, detaching, and replacing the two printing units by selectively moving and arranging them to printing positions. When printing a table, the frame line of the table is printed using a dot matrix, and the characters within the frame line are printed using type. Printing can be performed optionally, and the characteristics of both printed portions can be fully utilized, and clear printing can be performed at high speed.

Further, according to the present invention, it is only necessary to provide one printing ribbon that is shared by both parts, and the configuration can be extremely simplified.
