Abstract

PURPOSE:To print two papers with characters with the same color simply and simultaneously without using a copy medium such as pressure sensitive paper, in the titled printing system, by using recording paper consisting of base paper and ink permeable copy paper. CONSTITUTION:Copy paper good in ink permeability (and/or penetratability) (e.g., stencil base paper for a typewriter) is superimposed on base paper low in ink blotting property (e.g., base paper for single form paper, base paper for continuous form paper) and the end parts of both of them are fixed in a separable manner by a size to form recording paper 4. When the resulting recording paper 4 is mounted so as to confront the side of the base paper 2 to a platen 1 and the wire 5 of a printer is moved to the side of the platen 1 to be brought into impactive contact with the recording paper 4, the ink 6 adhered to the leading end of the wire 5 is transferred to the copy paper 3 while permeating through the copy paper 3 to be adhered to the surface of the base paper 2 thereby the copy paper 3 and the base paper 2 are simultaneously printed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing method and recording paper for an ink-type wire dot printer that can simultaneously print the same color on two sheets of paper without using a copying medium such as pressure-sensitive paper. be.

Traditionally, wire dot printers have been divided into two types: one that uses the impact of a wire to print on printing paper via a ribbon, and the other that prints by sliding a wire with ink attached to the tip and applying ink directly to the printing paper. is known.

When trying to make copies using these, it is common practice to interpose a copying medium such as carbon paper between two sheets of printing paper, but it is common practice to insert a copying medium such as carbon paper between two sheets of printing paper. However, it is difficult to make the original and the copy the same color, and this becomes even more difficult when color ink is used. Furthermore, the impact force of the wire must be increased, and the problem remains that the drive power source increases and the drive IIJ device tends to increase in size. It was a cabinet. Recently, in order to obtain copies of the same color, the information to be printed is stored in a storage medium such as a floppy disk, and after - times of printing, the stored information is read out and reprinted.

Problems remain in terms of total cost.

Therefore, it is an object of the present invention to simultaneously obtain copies of characters, numbers, figures, etc. (hereinafter referred to as 2 characters, etc.) printed on the original in the same color without using a copying medium.
It is possible to reduce the total cost and suppress the increase in impact force.

It is an object of the present invention to provide a printing method and recording paper for an ink-type wire dot printer that is particularly suitable for color ink.

The present invention will be explained below with reference to the drawings. A platen 1 is provided with a base paper 2 such as a base paper for continuous slips, a base paper for single slips, etc., which does not bleed ink easily, and a stainless steel plate for a typewriter placed on the base paper.

Ink permeability such as base paper for filters, base paper for P paper, etc. and /'! A recording paper 4 made of a copy paper 5 having excellent permeability is placed and supported. 5 is ink 6 on the tip
The wire 5 is arranged so that it can move forward and backward with respect to the platen 1.

To explain in detail about the copy paper 3 that constitutes the recording paper 4 together with the base paper 2, when the ink 6 collides with the copy paper 3,
In order to ensure that the ink 6 quickly reaches the base paper 2,
It is preferable to use copy paper 5 having a characteristic that the ink moves quickly in the direction of the platen (thickness direction) rather than in the lateral direction. However, as shown in FIGS. 2 and 6, in the case of short recording paper 4 such as cut paper, only the leading edge of the base paper 2 and the copy paper 3 are glued together. If the recording paper 4 is a long recording paper such as a roll paper or is cut as appropriate, the base paper 2 and the copy paper 5 may be prevented from separating after being cut as appropriate. In order to prevent wrinkles from forming on the copy paper 6, various methods may be used, such as fixing one side edge of the base paper 2 and the copy paper 3 with glue or the like.

That is, various types can be adopted as long as at least one end of the base paper 2 and one end of the copy paper 3 are separably fixed.

Next, the operation will be explained with reference to FIG. Ink 6 on the tip
The wire 5 to which the ink is attached moves forward in the direction of the platen 1, and the tip of the wire 5 collides with the copy paper 3, and the ink 6 is transferred to the copy paper 3.

A portion of the ink 6 passes through or penetrates the copy paper 3 and moves to the back side of the copy paper 3. The ink 6 that has reached the long side of the copy paper 3 adheres to the surface of the base paper 2, and
The characters printed on the paper and the characters of the same color are transferred to the base paper 2,
Characters, etc. of the same color can be obtained on the copy paper 6 and the base paper 2 at the same time.

According to the present invention as described above, a copy in the same color as the characters printed on the original can be obtained at the same time without using a copying medium, and it is possible to reduce the total cost and suppress the increase in impact force. Moreover, even when using multiple colors, it has the great effect of making it possible to obtain a color copy with the same color as the original.

Note that the description of the ink-type wire dot printer device has been omitted since it is outside the gist of the present invention, but it can be applied to various applications as long as it directly transfers ink attached to the tip of the wire onto recording paper. It is.
