The present invention has been completed based on the above circumstances. That is, an object of the present invention is to provide a simple press type printing apparatus having a simple structure with a small number of parts and capable of performing high quality stencil printing.

[0011]

According to a first aspect of the present invention for solving the above-mentioned problems, a pressing plate to which a printing original plate is detachably attached, a pressure-receiving plate for holding an object to be printed, and the pressing plate are provided. A simple pressing type printing apparatus, characterized in that the hinge part connecting with the pressure receiving plate has a pressure body integrally formed of the same material, and the pressure body has flexibility, According to a second aspect of the present invention, at least one of the surface of the pressure plate facing the pressure receiving plate and the surface of the pressure receiving plate facing the pressing plate is provided with a pad for placing a base paper or an object to be printed. And the pad is formed of an elastic body having a non-linear displacement amount within a range of pressing force required for press printing, and the pressing body has an elastic body having a linear displacement amount within a range of pressing force required for press printing. The above-mentioned claim 1 formed by A simple press-type printing apparatus according,

According to a fourth aspect of the present invention, the hardness of the ink used for the printing original plate is 40 as a 1-minute value measured by a spread meter.
The simple pressing type printing apparatus according to claim 2 or 3, which is the following.

[0012]

In the simple pressing type printing apparatus of the present invention, the pressurizing main body is composed of the pressure receiving plate, the pressing plate and the hinge portion connecting them, and since these are integrally molded, they are added as basic parts. Since the pressure main body and the pad are used, the number of parts is small and the structure is simple.

The pad may be provided only on the surface of the pressing plate facing the pressure receiving plate, or may be provided only on the surface of the pressure receiving plate facing the pressing plate, and the pad of the pressing plate may be provided. It may be provided on both the surface facing the pressure receiving plate and the surface of the pressure receiving plate facing the pressing plate.

Since the pad has the same function regardless of whether the pad is provided on the pressing surface or the pressure receiving surface, or on both of them, in the following, an example in which the pad is provided on the pressure receiving surface will be described. The operation of this simple pressing type printing apparatus will be described with reference to FIG.

Press printing by this simple press printing device is performed as follows.

The hinge portion is bent so that the pressure receiving plate and the pressing plate face each other. The print substrate is placed on the placement surface of the pad. The printing original plate is attached to the pressing plate. The pressing plate is pressed against the pressure receiving plate by, for example, placing both hands on the surface of the pressing plate opposite to the surface facing the pad. The ink in the printing original plate migrates to the surface of the printing material and printing is performed on the printing material.

At this time, the pad is formed of an elastic body having a non-linear displacement amount within a pressing force range required for press printing, and the pressing body is linearly displaced within a pressing force range required for press printing. Since it is formed of an elastic body having, for example, the pressing force by the hand is evenly distributed on the pressing plate and the pressing plate, and the pressing force applied to the pad is also uniformly distributed. As a result, there is no dark and thin printing unevenness on the printing material, and the ink is smoothly transferred from the printing original plate to the printing material to form a clear image on the printing material.

When the pressurizing body and the pad are made of an elastic body having the above-mentioned characteristics, the pressing force is evenly distributed, and as a result, clear printing that is neither too dark nor too thin is possible. Although not clear yet, the present inventors consider as follows.

In a conventional press type printing apparatus having a mounting table on which a material to be printed is mounted and a pressing member which applies a pressing force to the material to be printed on the mounting table via the printing original plate, the hardness of the mounting table is Since the pressing member is made of a material having much higher hardness, for example, hard plastic or metal, the pressing force by the hands when pressing the pressing member with both hands is directly transmitted to the mounting table. The hand pressing force applied to the surface of the pressing member opposite to the surface facing the mounting table is a local pressure. Therefore, even if the mounting table is formed of a flexible member, it is presumed that local pressure is applied to the printing original plate through the pressing member, resulting in uneven printing on the printing material.

However, in the simple pressing type printing apparatus of the present invention, when the pressing force applied to the pressing main body with, for example, both hands is increased, neither the pressing main body nor the pad is largely deformed at the initial stage of applying the pressing force. It is presumed that this is because the pressing force applied is dispersed in the pressurizing body, and the dispersed pressing force is applied to the pad. When the pressing force applied to the pressurizing body by, for example, both hands exceeds a certain value, the pad undergoes a non-linear displacement and is rapidly deformed. At this time, the pressurizing body is slightly deformed due to the pressing force, but is not causing a rapid nonlinear displacement.Therefore, the pressing force dispersed by the pressurizing body is applied uniformly and largely to the mounting surface of the pad. It is estimated that this will be done.

This pressurizing body is based on the Japan Rubber Association Standard S
The hardness measured by the hardness meter indicated by ris-0101 is 7
When the pad is formed of an elastic body having a hardness of 0 to 120 Hs, and the pad has an hardness of 20 to 60, which is measured by a hardness meter indicated by Japanese Rubber Association Standard Sris-0101, Easily generates non-linear displacement within the range of pressing force.

Further, when the hardness of the ink adhered to the printing original plate is 40 or less in 1 minute value measured by the spread meter, the transition from the printing original plate to the non-printed material becomes smooth within the range of the pressing force by hand.

When the pad is removable from the pressure receiving plate,
Easy pad replacement.

In this embodiment, the thickness of the main body 2 of the printing apparatus is appropriately designed within a range of usually 10 to 25 mm when printing on a postcard-sized object to be printed by the simple press type printing apparatus, and the elastic pad is used. The thickness of 7 is usually 10 m
Designed not to fall below m.

A stencil printing plate mounting member for mounting the stencil printing plate is provided on the surface of the pressing plate 4.

Here, the stencil printing original plate is the actual kai 51-
It is possible to use an original plate having the structure described in JP132007. To explain briefly, as shown in FIGS. 4 and 5, the stencil printing plate 8 includes a frame-shaped frame 8a made of cardboard and a heat-sensitive material attached to one surface of the frame 8a. The stencil printing base paper 8b and an ink impermeable ink cover sheet 8c that is openably and closably attached to the other surface of the frame 8a. The heat-sensitive stencil printing base paper 8b and the ink are provided inside the frame 8a. A relatively hard printing ink can be stored in the space 8d formed by the cover sheet 8c.

It is preferable that the printing ink flow with a force within the range of the pressing force at the time of press printing, and in a normal case, for example, the l minute value by a spread meter is 4
It is set to 0 or less.

As shown in FIGS. 1 to 3, the stencil printing plate mounting member for mounting the stencil printing plate 8 is folded back at the hinge portion 5 on the upper surface of the pressing plate 4, that is, the printing apparatus main body 2. In order to lock the longitudinal edge of the stencil printing plate 8 on the surface facing the pressure receiving plate 3 when the pressure plate 3 is opened, it is provided near one end of the pressing plate 4 and near the large second groove 5b in the hinge portion 5, respectively. A pair of first locking members 9a,
The stencil printing plate 8 has a second locking member 9b that locks the protruding piece 8e, and a positioning projection 9c that fits into a cutout portion 8f provided in the stencil printing plate 8.

Denoted by 10 is a notch portion for facilitating removal of the stencil printing plate 8 mounted on the upper surface of the pressing plate 4.

What is important in the simple press type printing apparatus 1 having the above-mentioned mechanical structure is that the foam forming the printing apparatus main body 2 has elasticity that has a linear displacement amount within the range of the pressing force required for press printing. The elastic pad is formed of an elastic body having a non-linear displacement amount within a range of pressing force required for press printing.
Further, it is preferable that the foam constituting the printing apparatus main body 2 has a hardness of 70 to 120 Hs, which is measured by a hardness meter shown in Japanese Rubber Association Standard Sris-0101, and the pad has a hardness of Japan Rubber Association Standard Sris
20 as the value measured by the hardness meter indicated by -0101
It is preferably in the range of -60 Hs. Within such a hardness range, the hardness of the elastic pad 7 is higher than that of the printing ink and lower than that of the foam forming the pressing plate 4 and the pressure receiving plate 3, and the hardness of the printing ink and It is preferably designed to have a hardness intermediate to that of the foam.

Specifically, as shown in FIG. 6, when the pressing force is increased, the foam constituting the printing apparatus main body 2 in this embodiment is gradually deformed and linearly displaced in accordance with the increase amount. The displacement point is shown at about 600 g / cm ² , which is outside the range of pressing force required for press printing. The elastic pad exhibits a non-linear displacement within the range of pressing force required for press printing, for example, about 80 g / cm ² as shown in FIG. The specific hardness of the printing apparatus main body 2 was about 85 Hs, and about 93 Hs when a hard feeling was obtained. The specific hardness of the elastic pad is around 40 Hs.

The pressing force required for press printing is usually 8
It is 0 to 200 g / cm ² .

In the simple pressing type printing apparatus of the present invention, the printing apparatus main body 2 can be formed by suitably adopting a foamed body of thermoplastic resin such as polyethylene or polypropylene or a foamed body of polyurethane. Further, the elastic pad can be formed by using foams of various materials as long as it has the above-mentioned non-linear displacement amount, and as such a material, foams of thermoplastic resin such as polyester and polyether are appropriately selected. The foaming density of this foam is usually 50 to 120, although it depends on the material.
It is kg / m ² .

The stencil printing is performed as follows by using the simple pressing type printing apparatus having the above-mentioned structure.

That is, first, an object to be printed, such as a postcard 11, is placed on the upper surface of the elastic pad 7. Then, the edge piece of the stencil printing plate 8 in which an ink of an appropriate color is loaded is placed between the heat-sensitive stencil printing paper 8b and the ink cover sheet 8c.
The stencil printing plate 8 is slid on the surface of the pressing plate 4 while being locked by the locking member 9a, and the protruding piece of the stencil printing plate 8 is locked by the second locking member 9b. The positioning protrusion 9c is arranged in the cutout portion 8f of the groove 8.

After that, the printing apparatus main body 2 is hinged to the hinge portion 5.
And the upper surface of the pressure receiving plate 3 and the upper surface of the pressing plate 4 face each other. At this time, the large first groove 5a and the large second groove 5
b means that the inside of the groove is crushed and the medium-sized first groove 5c
Since the groove is enlarged with the middle-sized second groove 5d and the small groove 5e is slightly expanded, the pressing plate 4
And the upper surface of the pressure receiving plate 3 face each other substantially in parallel.

In this state, as shown in FIG. 8, the upper surface of the folded pressing plate 4 (the surface which was the lower surface before folding) is pressed by hand.

The thickness of the foam forming the printing apparatus main body 2 is within the range described above, and the foam does not exhibit non-linear displacement within the range of the pressing force required for press printing. Even if the plate 4 and the pressure receiving plate 3 are slightly distorted, the surface of the pressing plate 4 facing the pressure receiving plate 3 and the surface of the pressure receiving plate 3 facing the pressing plate 4 are kept substantially parallel to each other, so that the pressure receiving plate 4 and the pressure receiving plate 3 receive pressure. The stencil printing plate 8 and the postcard 11 interposed between the plate 3 and the plate 3 are held substantially parallel to each other.

When the pressing plate 4 is pressed with a hand, a pressing force is applied to the surface of the pressing plate 4 with which the palm comes into contact, but when a certain pressing force is reached, the elastic pad 7 exhibits a non-linear displacement. That is, the printing apparatus main body 2 is not largely compressed, but the elastic pad 7 is compressed. At this time, since the foam forming the printing apparatus main body 2 does not exhibit non-linear displacement, the surface of the pressure receiving plate 3 facing the pressing plate 4 is not yet deformed, and the elastic pad is the flat surface of the pressure receiving plate 3 which is not deformed. Since 7 is compressed, the detailed mechanism for transmitting the pressing force is not clear, but the stencil printing plate 8 and the postcard 1
1 is sandwiched between the pressing plate 4 and the elastic pad 7 with a uniform force and is pressed. As a result, high quality stencil printing without printing unevenness can be provided on the surface of the postcard 11.

-Experimental Example- The foam has a shape shown in FIGS.
Postcard printing was performed using the simple pressing type printing apparatus 1 having a hardness of 5 Hs and a hardness of the elastic pad 7 of 40 Hs.

The hardness of the foam and the hardness of the elastic pad 7 are the values measured by an ASKER-C type hardness meter manufactured by Kobunshi Keiki Co., Ltd., which is shown in Sris-0101, a standard plan of the Japan Rubber Association. . The relationship between the weight and deformation of the foam is shown in FIG. 6, and the relationship between the weight and deformation of the elastic pad is shown in FIG.

By pressing the pressing plate 4 with both hands, the master plate 8 for stencil printing was pressed and brought into close contact with the postcard 11. As a result, a stencil-printed postcard without uneven printing was obtained.

In this case, since the printing apparatus main body 2 having an appropriate hardness in which the pressing plate 4, the pressure receiving plate 3 and the hinge portion 5 are integrally formed has a flexible structure, even if pressure is applied with both hands,
That is, even if partial pressure is applied to the pressing plate 4 by the palm, it is considered that parallel and uniform pressure is applied to the stencil printing plate 8 and the postcard 11.

(Modification) In the above embodiment, the size of the metal plate is set to a postcard size. However, the size is not limited to the postcard size, and is the same as the upper surface of the pressure receiving plate, for example. Alternatively, it may be an appropriate size between the size of the postcard and the size of the upper surface of the pressure receiving plate.

In the above embodiment, the metal plate is inseparably fixed to the pressure receiving plate by, for example, an adhesive, and a thin magnet plate is attached to the back surface of the elastic pad, so that the elastic pad is attached to the pressure receiving plate. It can be attached and removed freely.

When the elastic pad is detachable from the pressure receiving plate in this way, the elastic pad can be easily replaced, and the elastic pad for mounting the printing object on the printing original plate can be easily positioned. be able to.

In the present invention, the detachable attachment of the elastic pad to the pressure receiving plate is not limited to the attachment by the magnet plate. For example, as shown in FIG. 9, a plate-shaped magnet piece 12 is fixed to the pressure receiving plate 4 with an adhesive or the like, and a flat metal plate 6 of the elastic pad 7 is fixed to the lower surface of the elastic pad 7 with an adhesive or the like. Alternatively, a metal plate fixed to the lower surface of the elastic pad with an adhesive, for example, may be attached to the upper surface of the pressure receiving plate 4 by a magic fastener or the like.

In the simple pressing type printing apparatus of the present invention, as shown in FIG. 10, a positioning member 13 may be provided on the edge of the elastic pad 7. By providing the positioning member 13, for example, a postcard can be placed on the upper surface of the elastic pad 7 with high positioning accuracy.

The positioning member 13 has a height higher than the mounting surface of the elastic pad because it is necessary to position the object to be printed on the elastic pad. Therefore, when the pressure receiving plate presses the elastic pad, the pressure receiving plate comes into contact with the positioning member before the pressure receiving plate comes into contact with the elastic pad. Therefore, it is desirable that the material of the positioning member 13 has the same hardness as the elastic pad, or has a smaller hardness than the elastic pad.

The positioning member 13 and the elastic pad may not be fixedly bonded. Positioning member 1
Since 3 and the elastic pad are not adhered and are independent of each other, the elastic pad is not deformed even when the positioning member is first crushed during press printing, and the elastic pad is not contacted until the printing original plate hits the elastic pad. Press the printing original plate in parallel.

As shown in FIG. 11, the pressure plate 3 is provided with a notch 14 at the end thereof, and the pressing plate 4 is provided with an engaging portion 15 to be engaged with the notch 14 at the tip end thereof. The pressure receiving plate 3 and the pressure receiving plate 3 may be joined at their ends.

In the above embodiment, the pad is attached to the surface of the pressure receiving plate facing the pressing plate. In the present invention, as shown in FIG. 12, the pad may be attached to the surface of the pressing plate which faces the pressure receiving plate, or
Pads may be attached to both surfaces of the pressure plate facing the pressure receiving surface and the surface of the pressure receiving plate facing the pressing plate as shown in FIG.
