Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a printing method using a hard porous printing material such as a ceramic printing material or a sintered metal printing material, which has innumerable continuous pores and is not compressed by the imprinting operation. Related to the improvement of.

(Prior Art) A diameter-expanding cylinder portion for accommodating an ink occlusion body is formed at the lower end of a shaft cylinder portion, a porous stamp material having innumerable continuous pores is attached to the lower end thereof, and a grip cylinder is fitted to the shaft cylinder portion. The stamp made by fitting the stamp cap to the bottom of the stamp that is worn is SAIKAI Sho 63-1.
It is widely known as a convenient stamp that does not require ink to be attached each time it is used without needing to read the 41755 publication, but most of these stamps are porous stamps that have elasticity such as sponge rubber as porous stamps. Since the stamp material is used, the stamp material is flexible and the stamp surface is compressed and deformed by the stamping operation, so that it cannot be used as a certification stamp such as a real stamp. Therefore, it has been attempted to use a stamp material made of a hard porous stamp material having innumerable continuous pores that is not compressed by a stamping operation such as a ceramic stamping material or a sintered metal stamping material, but is not compressed by the stamping operation. Even if a hard porous stamp material is used for the same structure as a stamp using a conventional porous stamp material, it is not compressed by the stamping operation, and the hard porous stamp material has no cushioning force and is uncomfortable to use. In addition, there is a defect that the amount of ink bleeding from the printing surface is insufficient during continuous printing, making it difficult to continue clear printing. Therefore, we also tried to give cushioning property by the elastic force of the spring, but if the cushioning property is given by the elastic force of the spring, the amount of up and down increases, so it is possible to rotate the stamp material when moving up and down or to perform a smooth marking operation. There were problems such as making it difficult to do.

(Problems to be solved by the invention) The problem to be solved by the present invention is to eliminate the above-mentioned defects and to create a large number of continuous pores that are not compressed by the imprinting operation of a ceramic stamp material or a sintered metal stamp material. Along with making it possible to use it as a proof mark using a hard porous stamp material that has, it is possible to continue a clear stamp without running out the amount of ink bleeding from the stamp face even when performing continuous stamping, Moreover, it is an object of the present invention to provide an easy-to-use, inexpensive stamp that has a simple structure in which the stamping operation can be performed smoothly and the stamping material does not rotate during the stamping operation.

(Means for Solving the Problems) The seal of the present invention for solving the above problems is
A stamping main body is formed by forming a diameter-expanded cylinder portion for accommodating an ink occlusion body at the lower end of the shaft cylinder portion, mounting a porous stamp material having innumerable continuous pores at the lower end thereof, and attaching a gripping cylinder to the shaft cylinder portion. In a stamp formed by fitting a stamp face cap to the lower end, the porous stamp material is a porous hard stamp that is not compressed by the stamping operation, and the lower end of the tubular receiving member fitted to the expanded cylinder portion is A vertically slidable fit is held between the inner collar portion and the lower end of the diameter-expanding cylinder portion, and an elastic ring is interposed between the rear peripheral edge of the porous hard stamp and the lower end of the diameter-expanding cylinder portion, Further, a continuous guide groove is provided at a required position on the peripheral surface of the porous hard stamp and the elastic ring, and guide pins, both ends of which are in contact with each other, are interposed between the lower end of the diameter-expanding cylinder portion and the inner flange portion. It is characterized by.

(Operation) Such a stamp is made of a hard stamper which does not compress and deform by removing the stamping face cap, gripping the gripping cylinder, bringing the stamping face of the porous stamping material at the lower end into contact with the stamped face, and applying a pressing force. All that is necessary is to stamp the elastic ring with the stamp surface of the porous stamp material, and during this time, the porous hard stamper slides upward against the elastic force of the elastic ring in the cylindrical receiving plate and slides back. The ink is replenished by the compression of the ink occlusion body along with, and the ink surface is sufficiently replenished with ink for the next marking. Further, the vertical movement of the porous hard stamp during the marking operation is performed under the guide of the guide groove and the guide pin provided between the porous hard stamp and the elastic ring between the lower end of the expanded diameter cylinder portion and the inner flange portion. Therefore, even when the porous hard stamp is slid up and down, it does not rotate and the marking operation is extremely smoothed.

(Example) Next, this invention is demonstrated in detail about the Example shown in figure.

(1) is a stamp main body, and the stamp main body (1) has a cylindrical holder (3) in which a diameter expansion cylinder portion (3) for accommodating an ink occlusion body (4) is formed at a lower end of a shaft cylinder portion (2). 1a), a porous hard stamp (5) attached to the lower end of the expanded diameter cylinder (3), and a grip cylinder (7) fitted to the shaft cylinder (2) via a spring (6). ) And. The porous hard stamp (5) is formed by firing together with the stamp face (5a) with a material having innumerable continuous pores that is not compressed by the stamping operation such as a ceramic stamp or a sintered metal stamp. , This porous hard stamp (5) has an inner collar (8
a), the tubular brim (8) is formed, and the collar-shaped part (5
b) is vertically slidably fitted and held so that it is supported by the inner flange portion (8a), and the cylindrical receiving member (8) is attached to the expanded cylindrical portion (3) by the porous hard stamp. An elastic ring (9) made of synthetic rubber or the like is fitted and fitted between the peripheral edge of the upper surface of (5) and the lower end of the expanded diameter tubular portion (3). (10), (11)
Is a semicircular diameter guide groove provided at the corresponding positions of the peripheral edge of the porous hard stamp (5) and the peripheral edge of the elastic ring (9), and the guide grooves (10) and (11) are expanded cylinders. The vertical sliding of the porous hard stamp (5) is guided by the guide pin (12) between the lower end of the part (3) and the inner flange part (8a) by interposing guide pins (12),
It is designed to be smoothly guided under the guidance of (11) and the guide pin (12). (13) is a stamp face cap fitted to the lower end of the stamp main body (1), and the stamp face (5a) of the porous hard stamp plate (5) is attached to the inner bottom surface of the stamp face cap (13) when the lid is applied. A non-porous elastic disk material (14) such as silicon rubber is provided which is in close contact with the. Reference numeral (15) is an ink replenishment cartridge which is removably inserted into the shaft cylinder (2), and the ink replenishment cartridge (15) has a step cap (17) at the upper end of the ink occlusion body (16). The step cap (17) is fitted with a spigot (18), and a spring (19) is interposed between the step cap (17) and the step cap (17). By fitting the mouth plug (18) into the upper end opening of the shaft cylinder (2), the lower end of the ink storage rod (16) is constantly pressed against the upper surface of the ink storage body (4) by the elastic force of the spring (19). The ink occlusion rod (16) is used to replenish the ink occlusion body (4) with ink, and (20) is a vertical position indicator fitted vertically on the outer body of the gripping cylinder (7). It is a different color member for. It is particularly preferable that the printing surface (5a) of the porous hard stamp (5) is subjected to a grinding treatment after molding and firing of the porous hard stamp (5).

In such a structure, the non-porous elastic disc material (14) such as silicon rubber, which has the stamp face cap (13) on the inner bottom surface at the lower end of the stamp main body (1), is usually porous. Since the hard stamp (5) is fitted in close contact with the stamp face (5a), there is no volatilization of ink or transfer to the elastic stamp member (14). As described above, since the exuded ink is adhered in a film form on the printing surface (5a) of the porous hard printing plate (5) which is in close contact with the non-porous elastic printing plate material (14), the gripping is performed. If the stamp surface (5a) of the porous hard stamper (5) exposed from the lower end of the cylinder (7) is held in contact with the stamped surface and a pressing force is applied, the guide grooves (10), (11 ) And the guide pin (12), the porous hard stamp (5) smoothly slides upward against the elastic force of the elastic ring (9). However, clear marking is performed with the film-like ink adhered to the printing surface (5a) of the porous hard stamp (5) which is not compressed and deformed, and this marking operation is performed by the elastic ring (9). Since it is performed under the blast, a comfortable feeling of use can be obtained. further,
During the imprinting operation, the porous hard stamp (5) is slid upward in the cylindrical metal receiving member (8) to compress the ink occlusion body (4) attached to the back surface thereof, so that it is compressed. Upon receiving the replenishment of the ink stored in the ink occluding body (4), the ink surface (5a) is sufficiently replenished with ink for the next imprinting.

(Effect of the Invention) As is apparent from the above description, the present invention uses a porous hard stamp having innumerable continuous pores that is not compressed by the stamping operation of a ceramic stamp or a sintered metal stamp. It can be used as a proof mark by eliminating the compression deformation caused by the pressing operation, and even if continuous marking is performed, clear marking can be continued without the ink bleeding amount from the printing surface becoming insufficient. The structure is simple and can be provided at low cost, and it is comfortable to use because it has appropriate elasticity when stamping, and the vertical sliding of the porous hard stamp is between the lower end of the expanded cylinder part and the inner collar part. Since it is performed under the guidance of the guide groove and the guide pin provided from the porous hard stamp to the elastic ring, it does not rotate even when the porous hard stamp slides up and down, and the marking operation is extremely smooth. There are many advantages such as Further, as in the embodiment, the one in which the non-porous elastic disc material that is brought into close contact with the printing surface of the porous hard stamp at the time of applying the lid to the inner bottom surface of the stamp cap is provided more appropriately for the volatilization of ink. In addition to being prevented, a clear shadow can be obtained from the first marking.

Therefore, the present invention is of great practical value as a solution to the problems of the conventional type stamp.
