Abstract

PURPOSE:To enable printing on a free-size slip paper, by a construction wherein a printing mechanism part comprising a printing head and rollers with belts for feeding a printing paper and a platen mechanism part comprising a platen and freely rotatable rollers are separate from each other. CONSTITUTION:With a slip paper inserted into a paper-setting port 8, the paper is fed to the position of a printing head 2 by rollers with belt 4, and the head 2 prints on the slip while being moved along a platen 7. In the case of printing in the range of the width of the platen 7, the slip paper is printed while being moved in only forward and backward directions by the rollers with belts 4, and after the printing, the slip paper is fed to an outlet 9 and discharged by the rollers 4. In the case of printing on a slip paper larger than the width of the platen 7, printing is once conducted in the range of the width of the platen 7. Then, the paper is moved leftward or rightward by rollers with belts 10 to the next printing position for the paper, and the printing head 2 is moved along the platen 7 to the printing position, followed by printing.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a printer that prints on free-size cut sheets.

2. Description of the Related Art Conventionally, in this type of printer, the paper feed direction has been unified to be either forward or backward or up and down, and it has been possible to print only on cut sheets within a range within the running width of the paper.

Problems to be Solved by the Invention Conventional printers can print only within the movable range of the print head, so when printing on large paper sizes, a printer with a large size corresponding to the paper size is required. There is.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new printer which makes it possible to overcome the above-mentioned drawbacks inherent in the prior art.゛Means for Solving the Problems In order to achieve the above object, the printer according to the present invention includes a printing mechanism section consisting of a print head and a roller with a belt for feeding printing paper, a platen and a freely rotatable roller. The platen mechanism consists of a separate structure.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a sectional view of the left side showing one embodiment of the present invention.

Referring to FIG. 1, the printer main body 1 has a printer controller, drive units for various motors and magnets, and an interface connection unit with a host device. The wire dot pin 3 of the printing head, which is a feature of the present invention, is arranged to move from bottom to top. In addition, belted rollers are placed on the left and right sides to facilitate the running of the cut sheets.

On the upper lid 5 of the printer, a roller 6 whose rotational direction is free is arranged at approximately the same position as the belted roller 1 of the printer main body 1. The platen 7 is in close contact with the upper lid j,
The length should be approximately the same as the width of the printer main body l.

Figure 1 is a view of the printer of the present invention viewed from above, and includes a roller with a belt that rotates when running the ticket in the front-rear direction, and a roller with a belt IO that rotates when running the ticket in the left-right direction. This allows the paper to run forward and backward and left and right.

Next, the printing operation on cut paper will be explained.

In Figure 1, the cut sheet to be printed is inserted into the paper set slot (I).
When inserted into N)r, the cut sheet is fed to the position of the print head by a roller with a belt, and the print head moves along the platen 7 while running the cut sheet. When printing within the width range of the platen 7, the cut sheet is moved only in the backward direction by a roller roller with a belt, and when printing is completed, the cut sheet is
It can be discharged by sending it to UT) 9 in the direction of the output rod using a roller with a belt.

When printing on a cut paper larger than the width of the platen, the paper is printed within the width of the carrier platen, and then the belted roller 10 that runs in the left and right direction moves the cut paper to the next printing position. .

By moving the print head along the platen to the printing position, it is possible to print on a sheet of paper that is wider than the width of the platen.

As described in detail, according to the present invention, the printing mechanism section consisting of a print head and a paper feed belt and the platen mechanism section consisting of a platen and rotatable rollers are separated. By making the printer movable back and forth and left and right, it is possible to print on any size cut paper regardless of the size of the printer, making it possible to realize a compact printer that is not limited by the size of paper used.

Claims (1)

[Claims] By combining the printing mechanism consisting of a dot matrix print head and a roller with a belt for feeding printing paper, and the platen mechanism consisting of a platen and freely rotatable rollers, the number of single sheets used can be limited. This printer is characterized by being capable of printing on free-size cut paper.
