Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamping device using a stencil printing plate.

[0002]

2. Description of the Related Art Conventionally, stencil printing is carried out using a stencil base paper formed by selectively perforating a sheet obtained by laminating a stretched thermoplastic synthetic resin film and a porous support. Stamp devices have been proposed. Such a stamp device will be described with reference to FIG.

A stencil printing base paper 20 is wound inside a housing 11 between a delivery roller 12 and a take-up roller 14, and the stencil printing base paper 20 delivered from the delivery roller 12 is fed by a feed roller 13a. , 13b, and is wound around the winding roller 14. A thermal head 15 as a perforated image forming means is provided between the delivery roller 12 and the take-up roller 14 in the transportation path of the stencil printing base paper 20.

As the stencil printing base paper 20, for example, as shown in FIG. 2, a stretched thin vinylidene chloride-vinyl chloride copolymer synthetic resin film having a thickness of about 5 to 12 μm,
A thermoplastic resin film layer 21 such as a polypropylene synthetic resin film, and natural fibers such as Kozo, Mitsumata and Manila hemp, or synthetic fibers such as rayon, vinylon, polyester and acrylonitrile, metal, glass fiber and the like as the main raw material 8 The porous support layer 22 of about 12 to 12 g / m ² is used.

A handle 16 is slidably attached to the housing 11, and the pressing plate 1 is attached to the tip of the handle 16.
7 and the ink impregnated body 18 are provided. As the ink impregnation body 18, any porous body can be used as long as it can hold a large amount of ink, but a rubber porous body is used in consideration of pressure deformation and adhesion to the stencil printing plate. Most preferred is to use. Further, the housing 11 is provided with an input device 19 for inputting characters to be printed.

The operation of the stamp device having the above structure will be described. The stencil printing base paper 20 delivered from the delivery roller 32 is selected in accordance with the characters input by the thermal head 15 from the input device 19. The perforation is performed and the ink is conveyed to a position below the ink impregnated body 18. The perforated image is formed by instantaneous thermal rupture, and the stencil sheet 20 requires tension, so that the film can be stretched 2.5 times or more in the machine direction and the transverse direction, respectively. Is desirable. Then, by positioning the housing 11 on the transferred material and pressing the handle portion 16, the ink impregnated body 18 is pressed against the stencil printing base paper 20. Then, the ink in the ink impregnation body 18 passes through the perforated portion of the stencil printing base paper 20 by being pressed, and is transferred onto the transfer target to form an image.

[0007]

However, when using the above-mentioned stamping device, there is a possibility that a typographical error may be stamped or a wrong position may be stamped.

If stamped at the wrong position, if normal ink is used, a correction liquid of the same color as the transferred material is overcoated on the image to be erased, or a seal of the same color as the transferred material is applied. It is conceivable to overlap the above and erase them.

However, in the method of stacking the correction liquid or the seal having the same color as the transferred material, it is necessary to prepare a plurality of correction liquids or seals having the same color as the transferred material, and it is possible to deal with the transferred material of any color. However, it was impossible to deal with this, especially when the transferred material had a mottled pattern.

It is also conceivable to use an ink which can be decolored by a chemical reaction using a decoloring agent.
By using this method, it is possible to deal with transfer objects of any color or pattern.

However, just as the above erasing method requires a correction fluid, this method requires an erasing agent. Therefore, it takes a very long time to perform the erasing work such as the time for applying the decoloring agent and the drying time, and in particular, it takes more labor for the operator to erase the image formed on the entire surface of the paper, and the paper should be reused. Was near impossible.

On the other hand, a method of using an ink containing a colorant that is decolorized by ultraviolet light can be considered. With this method, it is possible to erase an image by simply irradiating the image to be erased with ultraviolet light, so it is possible to erase an image of a large area in a short time, greatly reducing the labor of the operator. It is also possible to reuse paper.

However, since ultraviolet light is required for decoloring, a mercury lamp, a xenon lamp, a deuterium lamp or the like is required as a light source. Therefore, the stamp image erasing device is not only very expensive,
Increasing the size is unavoidable and will hinder transportation. Furthermore, safety measures against ultraviolet rays are also indispensable, and if a light source is attached to the stamp device itself and the stamp is accidentally stamped, the stamp image can be immediately erased, and the device is small and does not hinder portability. There was no such stamping device.

The present invention has been made in order to solve the above-mentioned problems, and even if a wrong image is stamped or a wrong position is stamped, it is attached to the apparatus. With the stamp image erasing device, you can quickly and safely erase a large number of stamp images at once regardless of the shape or color of the transferred material.The erasing device is small and lightweight and can be attached to the stamp device. It is an object to provide such a stamping device.

[0015]

In order to achieve this object, a stamp device of the present invention comprises a data input device for inputting data of a desired shape, a stencil printing base paper,
A perforated image forming means for forming a perforated image of the above-mentioned data shape on the stencil printing base paper, an ink impregnated body impregnated with an ink that is erased by near-infrared light, and the stencil base paper after the perforated image formation described above The pressure plate for pressing the ink impregnated body and the stamp image erasing device are provided with a light source that emits near infrared light such as a halogen lamp.

[0016]

In the stamping device of the present invention having the above-mentioned structure, a perforation image is formed on the stencil printing base paper by a perforation image forming device such as a thermal head, and the stencil printing base paper after the perforation image formation is close to the stencil printing base paper. An ink impregnated body impregnated with an ink that is decolorized by infrared light is pressed against a transfer target, pressed against the transfer target, and the ink is stamped on the transfer target to form an image. However, if it is necessary to erase the stamp image, such as when you make a mistake in the stamp position on the image, the light source that emits near-infrared light attached to the device makes it easy to use even a large number of stamp images at once. The stamp image can be erased quickly and safely. The light source that emits near-infrared light as a stamp image erasing device is much simpler than a light source that emits ultraviolet light such as a halogen lamp. Therefore, even if it is installed in the stamp device, the device must be large. In addition, there is no problem in transportation, and it is possible to provide a handy type device that can be easily carried.
