DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base provided with a plate-making table on which a recording medium is placed, and mounted on the base so as to be openable and closable to form a light source and a predetermined image. A cover on which a stencil sheet can be mounted, and wherein when the light source flashes by closing the lid, a stencil sheet can be used to make an image formed on a recording medium on the stencil sheet. The present invention relates to an attachment for a plate making device which is detachably attached to the plate making device.

[0002]

2. Description of the Related Art Conventionally, as a plate making apparatus capable of making an image formed on a recording medium on a stencil sheet, an apparatus using a so-called flash thermal copying system has been widely known. In this method, in general, a recording medium, a stencil sheet having an ink bleeding portion corresponding to a desired image, and a transparent plate are superimposed on a plate-making table in order, pressed from above, and the light source is flashed in a state of being in close contact with each other. By doing so, the light-absorbing substance contained in the recording medium absorbs light energy and converts it to heat energy, and the heat causes a hole in the contact portion with the stencil paper, and that portion becomes an ink exuding portion, An image is formed.

When making a stencil sheet by such a method, it is necessary that the recording medium and the stencil sheet be in contact with each other securely over the entire transfer area. About 300 g / cm ² is sufficient.
Even if you flash the light source under this pressure,
In most cases, the image of the stencil sheet is transferred to a recording medium without interruption.

[0004] On the other hand, the applicant of the present invention has proposed a method in which a light source is flashed in a state in which an original sheet on which a predetermined image is formed and a stamp substrate on which a stamp surface based on the image is formed are superposed. As a plate making device for making plates,
The one disclosed in Japanese Patent Application Laid-Open No. 11-77947 has been proposed. In this plate making apparatus, a tray that can be inserted and removed in a horizontal direction is provided in a side opening of the plate making apparatus body. And
On the base of this tray, cover the original sheet and the stamping substrate so that the pressing plate is laid down in a state where
When the engaging body rotatably mounted on one end of the base is raised upright, the engaging portion formed on the lower end of the engaging body engages with the protrusion formed on one end of the pressing plate. Then, the pressing plate is pressed, and the original sheet and the stamp substrate are pressed toward the base by the pressing plate.

When a stamp plate is produced by such a plate making apparatus, it is necessary to flash the light source while a sufficient pressure is applied to the stamp substrate. This is because the stamp substrate is formed of a porous resin, so that the light is emitted when the light source is flashed unless the surface of the stamp substrate is pressed and the pores are crushed to some extent. This is because melting deformation of the portion is not promoted. Therefore, as shown in FIG. 9, when the stamp substrate is formed of a porous resin, it must be compressed by at least 10% or more, preferably by 20% or more when the light source flashes. A good pressure value is 250
About 0 g / cm ² is desirable.

As described above, the plate making apparatus for producing a stamp plate requires a structure capable of pressing the stamp substrate with a remarkably high pressure as compared with the case of the plate making apparatus based on the flash thermal copying method. Things.

[0007]

However, in the former stencil making machine, in order to transfer the image of the stencil sheet to the recording medium without interruption, the stencil sheet and the recording medium are reliably transferred over the entire transfer area. However, there is a problem that the recording medium on the plate-making table cannot be pressed with a high pressure, so that the recording medium cannot be diverted to producing a stamp plate as it is.

Further, in the latter plate making apparatus,
Although the stamping substrate can be pressed with a high pressure, the stamping substrate is placed on the substrate of the tray with a pressing plate, and the structure is such that the engaging body is pressed upright and raised, so that the stamping substrate is pressed. When the substrate is pressed, the height of the entire tray is increased. Therefore, when the openable cover is closed, the light source flashes and the image of the recording medium placed on the plate making table is made on the stencil sheet attached to the cover. There was a problem that can not be.

FIG. 8C is a side view of the laminated stamp substrate, a transparent film, and a document sheet. FIG. 8D is a side view schematically showing a state in which light is applied to the light-transmitting cover. FIG. 8D is a side view schematically showing a stamp substrate on which a stamp surface is formed, a transparent film, and a document sheet. FIG.

The stamp substrate 60 has open cells,
It contains a porous material that can be impregnated with stamp ink and a light energy-absorbing substance such as carbon black dispersed therein. The basic material is a foamable resin material such as a polyolefin resin, a polyvinyl chloride resin, and a polyurethane resin, and preferably has flexibility (softness) when formed into a porous sheet. Therefore, as shown in FIG. 8A, pores of open cells are exposed over the entire surface 60A of the stamp substrate 60 before plate making.
The thickness of the stamp substrate 60 is about 1 mm to 5 mm.
As described above, when the surface side of the stamp substrate 60 is heated, it is melted by containing the light energy attraction material, so that the pores exposed on the surface are closed. Then, after the surface side is melted in a state where the stamping substrate 60 is pressed, the pores that are solidified and exposed on the surface are closed to form the ink non-leaching portion 63, and the pores that are not melted are exposed on the surface. Ink bleeding part 64
Becomes

The original sheet 62 is made of light-transmitting paper such as PPC paper (tracing original paper), and has a surface of any color such as black, white, gold, silver or the like before forming a stamp. A light-impermeable printed image 62A is drawn with non-permeable ink, an oil-based marker, paint, paint, or the like.

As shown in FIG. 8B, the original sheet 62
Is placed on the surface of the transparent film 61 with the printed image 62A facing down. Then, the transparent film 61 is interposed between the original sheet 62 and the surface 60A of the stamp substrate 60, and the three members are stacked. Then, the translucent cover 37 is covered from above the document sheet 62. Then, as described above, the pressing and locking lever 36 is rotated to lock the translucent cover 37 while pressing it against the tray 30, thereby compressing the stamp substrate 60. Thereafter, as shown in FIG. 8C, the cover 2 of the plate making apparatus 1 is closed to close the cover 2.
The flash valve 6 is flashed. Note that the irradiation light contains an infrared component.

The transparent film 60 is made of a stamp substrate 60.
Melting point (about 120 ° C for soft polyurethane resin,
(In the case of a soft polyolefin-based resin, the temperature is about 70 ° C.). As an example, a transparent PET (polyethylene terephthalate) resin film having a high melting point (about 230 ° C.) is preferable, and the thickness of the transparent sheet 22 is about 0.025 mm to 0.2 mm.

In this way, the light energy that has passed through the portion of the original sheet 62 other than the image 62A passes through the transparent film 61 as it is, and the light energy corresponds to the portion of the stamp substrate 60 other than the image 62A. The carbon black near the surface to be absorbed absorbs heat, and the surface 60A in that portion is heated and melted, and then solidified, the pores on the surface are closed, and an ink non-bleed portion 63 having a predetermined thickness is formed (FIG. 8 (D)). On the other hand, when the image 62A of the original sheet 62 is black including carbon black, the portion of the image 62A is heated by light energy irradiated from the direction of the translucent cover 37, and the temperature rises. In the portion of the transparent film 61 corresponding to 62A, heat is conducted in the horizontal direction or the like within the thickness of the film. In other words, the heat generated on the original sheet 62 side is absorbed and dispersed by the transparent film 61, the surface of the stamp substrate 60 corresponding to the imprint 62A is not heated, and the pores are formed according to the shape of the imprint 62A. The exposed portion becomes the ink exuding portion 64 (see FIG. 8D). When the imprint 62A is other than black, light energy is blocked and reflected by the imprint 62A,
The surface portion of the stamp substrate 60 corresponding to the stamp image 62A is not heated, and becomes the ink exuding portion 64 with the pores exposed.
Therefore, in this case, the transparent film 61 is not necessarily required.

After the flash of the flash valve 6,
When the translucent cover 37 is removed and the transparent film 61 and the original sheet 62 are removed from the stamping substrate 60, as shown in FIG.
The ink bleeding portion 64 is formed while the pores of the stamp substrate 60 corresponding to the portion 2A are exposed, and the pores other than the portion corresponding to the stamped image 62A are closed to form the ink non-bleeding portion 63. A stamp having a stamp surface can be created.
