JPS6241080A - Inpact stamp for carbon copying - Google Patents

Abstract

PURPOSE:To enable carbon copying to be performed simultaneously with stamping, by a system wherein a stamp formed of a hard material is given an impact to instantaneously exert a high pressure on a paper to be stamped. CONSTITUTION:In a first process, the stamp is formed from a rigid plastic, an ink is applied thereto, it is pressed against a paper to be stamped, and a hammer is strongly driven by a spring or the like to collide against the back side of the stamp, whereby a high pressure is instantaneously exerted on the paper surface by the face side of the stamp. As a result, the uppermost paper is printed in the ink, and underlying papers can be simultaneously subjected to carbon copying. In second process, the stamp is provided as a heavy large body serving also as a hammer, and is formed from a metal. After an outer cylindrical frame constituting a main body of the stamp is pressed against the surface of the paper to be stamped, the stamp with an ink applied thereto is strongly driven by a spring or the like from the depth of the cylinder to collide against the surface of the paper, giving the same result as in the first process.

Description

Detailed Description of the Invention (a) Purpose of the Invention At present, by writing on carbon copy paper used for office use with a hard brush such as a ballpoint pen, the paper is written using the strong pressure of the pen tip. Many structures are used in which the same character is simultaneously drawn on one to three sheets of paper under the , using carbon copying. An example is a bank transfer request form.

In order to produce multiple sets of Type 1 copies, each consisting of 2 to 4 copies, it is often necessary to repeatedly enter the same information, such as address and company name, many times. In some cases, it is inefficient to handwrite with a ballpoint pen or the like.

In addition, if you use a conventional rubber stamp, the pressure is weak and carbon copying is not possible, so you need to stamp not only the top paper, but also each sheet of paper below it. There is. This is also inefficient.

Furthermore, even when using conventional seals made of hard materials such as hard plastics and metals, if the stamp is stamped with the strength of a normal human's arm, there is insufficient pressure and it is not possible to make a clear carbon copy at the same time. , I guess this seal was struck on the paper it was supposed to be stamped on.

Strong pressure is applied only to the edges and corners, making it impossible to copy the entire thing.

However, machines that stamp stamps, such as typewriters and time recorders for labor management, are of a stationary type, and the paper to be stamped is moved and inserted into the machine for use. This is inconvenient because it cannot be easily carried and used.

Therefore, from the top of the carbon copy document, which is large enough to be grasped and stamped with one hand, and which is made up of 2 to 4 sheets stacked together, it is necessary to use the strength of an ordinary person's arm. If a seal existed that could print on all sheets of paper at the same time just by stamping it, office efficiency would improve. It is an object of the present invention to provide such a seal.

C) Structure of the Invention As an actual example of the present invention, a seal having the following structure is produced.

First, the seal plate is made of hard plastic, coated with ink, and pressed against the paper to be stamped with a hammer (hard and When objects (with large mass) collide, a strong instantaneous pressure is created between the front side of the plate and the surface of the paper. As a result, the topmost paper is printed with ink, and the paper stacked below can also be carbon-copied at the same time.

Second, the seal plate is a large block that also serves as a hammer, and is made of gold (for example, antimony). Then, after the cylindrical outer frame that makes up the seal body (this outer frame serves as a guide to determine the position of the seal without being stamped on it) is pressed against the surface of the paper to be stamped. From the back, the inked plate is strongly pushed out by a spring or other force and crashes into the paper. As a result, it serves the same purpose as "Part 1".

What is common to the above two examples is that the action of storing energy in a spring, rubber, etc. to release the hammer is done in the stroke of gripping the handle of the seal using the force of the grip. It's a method. Then, by strongly pressing the body of the seal against the paper to be stamped, the body or the space between the handle and the body contracts in the direction of the pressing force, and the energy M8N is applied in the contraction stroke. That's one method. When enough energy is stored in the spring or the like, the trigger is automatically activated and the hammer is ejected.

In addition, it is thought that this seal usually contains multiple characters rather than a single character, so in that case, rather than producing all the characters as one block as a single version, the version is made public and the - A single seal is made from a plurality of such print pieces and a plurality of hammers, with each piece containing only one or a few letters, and the timing of the impact of these plurality of hammers is slightly shifted. It is desirable to By doing so, the impact of the shakusakugetsu on the seal itself can be reduced, and if a thin glass plate is used as an underlayment, the risk of damaging it can be reduced.

When making a thin plate using hard plastic, the rigidity is usually not as high as that of metal, so the plate is made as a single piece and is equipped with multiple hammers, each of which has a slightly different timing. It is also possible to have a structure in which it is shifted and works in its exclusive part.

(c) Effects of the invention When writing address, company name, etc. on a set of carbon copy documents, which consist of 2 to 4 sheets stacked one on top of the other, in the past, it was necessary to write on the top paper of a set It was necessary to write by hand with a ballpoint pen, or use a rubber band to turn over each sheet of the set of documents one by one and stamp each sheet. However, when using the seal of the present invention, the purpose can be achieved simply by stamping the seal on the top paper of the set of documents.
It's time consuming. If the seal of the present invention is used when the same work needs to be repeated for many sets of G,
It is notable that it contributes to improving office efficiency.

Claims (1)

[Claims] This is a seal made to be held and stamped by hand, and the plate made of hard material momentarily applies high pressure to the paper being stamped by impact, resulting in simultaneous carbon copying (carbonless copying). Materials that have a structure that allows for copying (including copying that develops or colors when subjected to pressure, such as paper).
