DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp body, and more particularly to a stamp body in which a surface of an ink-impregnated body is covered with a heat-sensitive stencil sheet to form a stamp face, and a predetermined pattern such as characters is formed on the stamp face. The present invention relates to a stamp body in which, when a stencil printing plate is pressed against paper or the like, the ink of the impregnating body oozes out of the perforations to perform printing when the stencil printing plate is pressed against paper or the like.

[0002]

2. Description of the Related Art Heretofore, various stamps for printing a company name / address and other various character strings on paper or the like, in which a stamp surface portion is made of rubber, have been used. This type of stamp is expensive because the stamp is usually created individually according to the order, and the period from order to acquisition is long.

On the other hand, a desired dot pattern can be pierced by irradiating an infrared ray or a thermal head, and by penetrating ink from the perforation group, a heat-sensitive material that can be used for printing various patterns such as character strings, figures, and marks. A stencil sheet using a stencil sheet has been practically used.

As disclosed in Japanese Utility Model Application Laid-Open No. 5-74833, the applicant of the present application is a stencil printing plate mainly composed of the heat-sensitive stencil sheet and an impregnated body impregnated with ink. A stencil printing plate suitable for making a stamp instead of a stamp whose surface is made of rubber was proposed. This stencil printing plate is obtained by bonding a synthetic resin film to an impregnated body impregnated with ink and a frame surrounding the impregnated body, and applying a heat-sensitive stencil sheet to the surface of the impregnated body and the frame. It is a configuration in which it is bonded.

When the stencil printing plate is applied to a stamp, the stencil printing plate is adhered to the lower surface of a base of a stamp member having a grip portion via a cushion material, and the heat-sensitive stencil sheet is attached to a thermal head or the like. By punching a pattern such as a desired character string, a stamp formed of a stamp member and a stencil printing plate is printed on a sheet many times as in a normal stamp. You will get a stamp that you can do.

[0006] The applicant of the present invention has disclosed Japanese Patent Application Laid-Open No. Hei 4-2267.
As disclosed in Japanese Patent Publication No. 78-78, there has been proposed a stamping device including a stamp body and a heating perforation apparatus for forming a perforation in a stamp face of the stamp body. The stamp body therein is provided with a gripping portion, a main body case, a supply reel and a take-up reel provided in the main body case, for supplying and winding a tape-shaped heat-sensitive stencil sheet, and a perforated heat-sensitive stencil sheet. And an ink pad for supplying ink to the portion.

A long heat-sensitive stencil tape in the form of a tape is used for the stamp body in Japanese Patent Application Laid-Open No. Hei 4-226778. However, since only a very small portion of the heat-sensitive stencil sheet is used at all times, the heat-sensitive stencil sheet is used. The waste of gender stencil paper increases. In addition, since a long tape-shaped heat-sensitive stencil sheet, a supply reel, a take-up reel, and the like are provided inside the stamp body, the stamp body becomes large and difficult to use, and the manufacturing cost increases. Furthermore, since the ink pad is in contact with the tape-shaped heat-sensitive stencil paper, it is difficult to seal the ink pad so that the ink does not leak, and the ink is likely to leak.

For this reason, the applicant of the present application has filed Japanese Patent Application No. 5-329.
No. 657 proposes a stamping device comprising a stamping member capable of reducing the size, weight, and cost of the stamping member and preventing leakage of ink, and a heating punching device capable of punching a stamped surface of the stamping member. .

The stencil printing plate of the stamp body in this stamping device includes an impregnated body and a heat-sensitive stencil sheet which covers the surface of the impregnated body and forms a stamped surface portion. It is a small and lightweight configuration. Also,
Since the heat-sensitive stencil sheet is configured to cover the surface of the impregnated body in a fixed manner, the ink does not leak to portions other than the stamp face. And since it is constituted by the impregnated body impregnated with the ink, it is possible to supply the ink during printing for a long time without excess or shortage.

However, the applicant of the present application has found the following problems in the case where the surface of such an impregnated body is fixedly covered with a heat-sensitive stencil sheet to form a stamp face.

That is, for example, the air which has entered the impregnated body after the seal is inflated and the ink flows out from the perforated hole of the seal face, and the seal face may be covered with ink. The reason will be described. Since the impregnated body needs to ooze the ink by being pressed, the impregnated body is often made of an elastic foam of a synthetic resin material. And since it is fixedly wrapped with the heat-sensitive stencil paper, the air inlet / outlet is limited to the perforated hole. Then, since the ink is pressed out of the perforated hole by pressing the impregnated body, air may enter the impregnated body through the perforated hole after the perforation, and the impregnated body will contain air therein. In such a state, when the environment in the stamp body changes, for example, when the environmental temperature rises, the air in the impregnating body also expands. Therefore, the air tries to escape to the outside by the amount of the expansion, but the only escape area is the perforated hole. When only the air flows out of the perforated hole, the ink also flows out.

As described above, when the ink flows out of the perforated hole, the ink is transmitted to the front surface of the stamp surface, and the stamp surface is covered with ink. If you print without noticing it, you will not be able to understand the contents of the print, or your hands and the print object will be stained with ink.

Accordingly, an object of the present invention is to provide a stamp body which can prevent ink from leaking from a perforated hole even when air in an impregnated body expands due to a temperature change or the like, and can always perform beautiful printing.

[0014]

[0018] In the invention described in claim 4, the impregnated body is:
The stamp body according to claim 2 , wherein the stamp body is made of an elastic foam of a synthetic resin material.

[0019]

According to the first aspect of the present invention, a predetermined pattern such as a character or the like is formed in a dot shape by a thermal head. This is achieved by, for example, using a heating and punching device as disclosed in Japanese Patent Application Laid-Open No. Hei 4-226778, receiving input data such as characters and symbols input from input means, and driving and punching the thermal head to control the thermal head. Can be perforated.

The stamp body frame holder having the stamped surface portion thus provided has a grip portion . When the grip portion is gripped and the stencil printing plate is pressed against the surface of the sheet, the stencil printing plate is pressed. Since the ink of the impregnating body oozes out from the perforations of the heat-sensitive stencil sheet constituting the stamp face portion, a pattern such as a character is printed on the paper.

[0021] Here, the stamp body is impregnated body on the lower surface of the frame body held by the frame holder and is mounted, heat-sensitive stencil sheet forms a stamp surface portion I covering the exposed surface of the absorbing member I have. Therefore, during normal use, the ink does not leak to portions other than the stamp face, and ink can be supplied during printing for a long time without excess or shortage.

However, with this configuration alone, as described above, for example, the air that has entered the impregnated body after the sealing expands, causing ink to flow out of the perforated hole in the stamp face, and the stamp face to be covered with ink. However, according to the present stamp body, it is possible to prevent the ink from flowing out of the perforated hole of the stamp face and the stamp face being covered with ink even if the air expands as described above. .

That is, the frame holding member and the frame holder are held.
The first member of the frame holder is fitted by fitting the holding member.
An enclosure is formed by the inner wall and the inner wall of the frame. Soshi

During normal use,
No leakage and no printing
Ink can be supplied without excess or shortage. However, it is just this configuration
For example, as described above, impregnation after stamping
When the air that has entered the body expands,
Ink spills out of the hole and the stamped area is covered with ink.
It may be, but according to this stamp body,
Even if there is air expansion like this, ink can be

That is, according to the stamp body of the present invention,
If this happens, the ink outflow prevention member attached to the frame will be empty.
It allows air but does not allow ink to pass through, and the frame
To prevent the ink from flowing out to the upper surface side. Therefore, the frame
Ink spills to the top of the body, and as a result
Also prevents ink from flowing out from between the body and the frame holder.
Can be stopped.

In particular, as described in claim 4, the impregnated body is combined.
Considered to be made of elastic resin foam
However, such a foam allows air to enter inside.
Retention is more pronounced and can be extended
The advantage is that ink can be supplied at the time of printing
However, if the air expands, the stamped surface may
Inconveniences that can easily be seen also occur. According to the stamp body of the present invention.
If it is, the upper surface side of the frame allows air to enter and exit from the outside
In the impregnated body through the communication hole
This is because air can flow out to the upper body side.
This can prevent inconvenience.

There are roughly three possible locations for attaching the ink outflow prevention member to the frame in the second aspect. One of them is a case where it is attached to the opening on the upper surface side of the opening of the communication hole, and the other two cases are a case where it is filled in the communication hole and a case where the lower surface side is filled. This is a case where it is attached to the opening. Theoretically, there are these three, but since the impregnating body is attached to the lower surface side of the frame, if the ink outflow prevention member is attached there, there is always contact with the ink, and the function to release air is provided. In some cases, it cannot be used to its full potential. Further, when filling the inside of the communication hole, it is necessary to fill the communication hole so as not to form a gap so as to prevent the outflow of the ink. Therefore, as described in the third aspect, if it is mounted so as to cover the opening on the upper surface side of the opening of the communication hole, there is no gap, and there is no contact with a large amount of ink. Is preferably attached to this location.

When the operator turns on the punching switch after mounting the stamp body 1 as described above, a punching process is performed on the stamp face portion 33 of the stamp body 1. When the perforation process is completed, “End of perforation process” and “Please remove the stamp body” are displayed on the LCD 53, and the operator opens the opening / closing door 75 and removes the stamp body 1. When the gripper 2 connected to the frame holder 5 of the perforated stamp body 1 of the stamp face portion 33 is gripped in this way and the stencil printing plate is pressed against the surface of the sheet, the impregnated body 2 of the stencil printing plate is pressed.
7 is the heat-sensitive stencil sheet 2 forming the stamp face portion 33.
8, the pattern such as a character is printed on the paper.

Here, the stamp body 1 operates as follows.
It works.

An impregnating body 27 is mounted on the lower surface side concave portion 25 of the frame body 26 held by the frame holder 5, and the heat-sensitive stencil sheet 28 covers the exposed surface of the impregnating body 27 in a fixed manner so as to cover the stamping surface 3.
3. Therefore, during normal use, the ink does not leak to portions other than the stamp face portion 33, and the ink can be supplied during printing for a long time without excess or shortage.

However, with this structure alone, for example, the ink that has entered the impregnating body 27 after stamping expands, causing ink to flow out of the perforated hole of the stamp face portion 33, and
In some cases, the stamp body 1 is covered with ink. However, according to the stamp body 1, even if the air expands as described above, the ink flows out of the perforated hole of the stamp face section 33 and the stamp face section 33 is covered with ink. Can be prevented.

That is, the frame body 26 has its upper surface side recess 61
The communication hole 6 is held by the frame holder 5 so that air can enter and exit from the outside, and communicates between the upper-side recess 61 and the lower-side recess 25 to which the impregnating body 27 is attached.
9 are provided. Therefore, even if the air in the impregnating body 27 expands due to, for example, a temperature change,
The air in the impregnating body 27 flows through the communication hole 69 of the frame body 26 and flows out to the upper surface side recess 61 of the frame body 26, so that a so-called “escape” of air can be realized. Can be prevented from leaking out.

Even if only the communication hole 69 is formed, the air in the impregnating body 27 may flow into the upper surface side recess 61 if the upper surface side recess 61 of the communication frame 26 is a closed space. I can't do that, so I avoid it.
Therefore, "the state where air can enter and exit" here
This means that the airtightness is not a state in which there is no escape for the air, and the air is usually in a state where air can enter and exit unless the airtightness is particularly configured. In view of this point, in the case of the present embodiment, the frame 26 is attached to the frame holder 5 by passing the holding male member 67 of the frame 26 through the through hole 77 of the holding female member 76 of the frame holder 5. The first inner wall 71 and the second inner wall 73 are held.
Does not come into contact with the upper surface side recess 61 of the frame 26, and
Does not contact the frame holder 5. Therefore,
It is fully in a state where air can enter and exit.

As described above, the impregnated body 2 is changed by the temperature change or the like.
Even if the air in the air 7 expands, the expanded air can be released through the communication hole 69, so that the leakage of the ink from the stamp face portion 33 can be prevented, and beautiful printing can always be performed.

Incidentally, there is a possibility that the ink of the impregnating body 27 may flow out from the communication hole 69 to the upper surface side concave portion 61 of the frame 26 together with the air. However, in the case of this embodiment, FIGS.
As shown in (3), since the first and second inner walls 71 and 73 of the frame holder 5 and the inner wall 65 of the frame 26 form a triple enclosure, it is unlikely that ink leaks to the outside. However, the following configuration is more reliable in that ink does not flow out of the communication hole 69 itself.

For example, it is conceivable to attach an ink outflow prevention member to the opening of the communication hole 69 to the upper surface side concave portion 61. As this ink outflow prevention member, a porous material such as a porous material of ethylene tetrafluoride resin, which has a small hole diameter and hardly wets, which allows air to pass therethrough but prevents ink from passing therethrough, may be used. Note that the ink outflow prevention member may be fixed to the upper surface side recess 61 with an adhesive or the like, but in this case, care must be taken so that the opening of the communication hole 69 is not covered with the adhesive layer.

When such an ink outflow prevention member is attached, the upper surface side recess 61 of the frame 26 passes through the communication hole 69.
It is possible to reliably prevent the ink from flowing out. Accordingly, as a result, it is possible to prevent the ink from leaking outside from between the frame body 26 and the frame holder 5 and the like.

The frame 26 of the ink outflow prevention member
There are roughly three types of mounting locations for the device. One of them is, as described above, a case where the communication hole 69 is attached to the opening on the upper surface side concave portion 61 side, and the other two cases are a case where the communication hole 69 is filled into the communication hole 69 and a case where the lower surface is filled. This is a case where it is attached to the opening on the side recess 25 side. Theoretically, there are these three. However, since the impregnating body 27 is attached to the lower surface side concave portion 25 of the frame body 26, when the ink outflow preventing member is attached thereto, there is always contact with the ink and air There is a case where the function of letting go cannot be maximized. Further, when filling the inside of the communication hole 69, it is necessary to fill the communication hole 69 so as not to form a gap so as to prevent the outflow of the ink, so that the filling is difficult. Therefore, as described above, if it is attached so as to cover the opening on the upper surface side concave portion 61 side of the communication hole 69, there is no gap, and there is no contact with a large amount of ink. Preferably, it is attached.
