Description

The present invention relates to a two-stage fitting type seal structure.

A technique for selectively generating heat from a heating element of the thermal head while abutting the thermal head against a porous material and moving it relatively, and forming a desired stamp surface on the porous material to form a printed body is disclosed in Patent Document 1. It is known as shown in . The printed body and its frame are pushed into a frame in which an ink absorbing body is housed, and the printed body and the ink absorbing body are brought into close contact with each other, so that ink from the ink absorbing body is impregnated into the porous printed body.

In the above-described stamp configuration, since the stamp surface is facing upward and the ink storage body is working on the bottom, a malfunction may occur in which the printed body is accidentally pushed in during the pre-processing process before thermal processing.

Therefore, as shown in Patent Document 2, a stamp configuration is also known in which a printed body is attached to a frame and then subjected to thermal processing. In such a stamp configuration, a cartridge equipped with an ink absorber is temporarily fitted in a separate position, and then the cartridge is pushed in from the back side (lower side) of the stamp face to bring the printed body and ink absorber into close contact. A two-stage fitting type in which the final fitting is performed is known.

However, even in this case, since the end of the cartridge with the ink storage body protrudes from the end of the frame to which the printed material is attached, there is a risk of accidentally pushing the cartridge in during the pre-processing process of thermal processing. Ta. As a result, the ink storage body and the printing body come into contact early in the previous process, and thermal processing is performed with the ink impregnated into the porous material, resulting in the problem of the ink staining the inside of the processing machine. there were.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a stamp structure that prevents the cartridge from being accidentally pushed in in a pre-processing step of thermal processing.

The present invention, which was made to solve the above problems, temporarily fits a cartridge equipped with an ink absorber in a separated position to a frame body to which a printed body is pasted, and then inserts the cartridge into the frame body on which a printed body is pasted. The stamp has a two-stage fitting type stamp configuration in which the printing body and the ink absorbing body are pushed in from the side and the ink absorbing body is brought into close contact with each other. It is characterized by extending to .

Preferably, a guide groove extending in the rear direction is provided on the frame side, and a protrusion that fits into the guide groove is provided on the cartridge side.

Further, it is preferable that the cartridge has a structure in which a recessed portion is formed on the back side of the cartridge to receive an attachment for pushing the cartridge in when the cartridge is fully fitted.

In the stamp configuration of the present invention, the back end of the frame to which the print body is attached extends further back than the end of the cartridge, so there is a risk of the cartridge being accidentally pushed in during the pre-thermal processing process. gender can be resolved. At the start of thermal processing, the cartridge is pushed into the frame with the print material attached using a special attachment, so the inside of the processing machine does not get dirty.

Furthermore, if the frame body side is provided with a guide groove extending in the rear direction, and the cartridge side is provided with a protrusion that fits into this guide groove, the cartridge can be pushed into the frame body without wobbling laterally. Can be done.

In these figures, 10 is a frame made of resin, and is composed of an upper frame 11 and a lower frame 12 below it. In this embodiment, the frame 10 has a square shape, and the upper frame 11 has a square shape, and a square printed body 50 is pasted on the top thereof. The print body 50 is made of a porous material, and the state shown in the figure shows the state in which the print surface is flat before thermal processing is performed. Note that the shapes of the upper frame 11 and the printed body 50 are not limited to square shapes, but may be rectangular, circular, oval, or the like.

As shown in FIG. 4, the upper frame 11 is provided with rectangular hanging walls 13 hanging around the periphery, and inward hooks 14 are provided protruding from two opposing sides of these hanging walls 13. The lower frame body 12 also has a square frame shape, and a square hanging wall 15 is formed around the frame. A stepped portion 16 for attaching the upper frame 11 is formed at the upper part of the lower frame 12. Furthermore, a recess 17 for receiving the hook 14 of the upper frame 11 is formed on two opposing sides of the lower frame 12. Therefore, the upper frame 11 and the lower frame 12 are firmly connected so that they will not come off or shake.

As shown in FIG. 3, protrusions 18 are formed on two outer surfaces of the hanging wall 15 of the lower frame 12 on which the recess 17 for receiving the hook 14 is not formed, and a pair of protrusions 18 extending from both sides of the cap 19 are formed. A protrusion 21 formed on the inside of the arm 20 is fitted. The caps 19 are provided on both sides of the frame 10 and can be opened on both sides as shown in each figure. These caps 19 are closed to protect the printed body 50 when the stamp is not in use.

A cartridge 31 having an ink storage body 30 is fitted inside the hanging wall 15 of the lower frame 12. In this embodiment, the ink storage body 30 is a porous body having a rectangular parallelepiped shape, and stores ink therein.

As shown in FIG. 4, the cartridge 31 has an upper wall frame 33 extending upward and a lower wall frame 34 extending downward integrally formed around a central square flat plate portion 32 that receives the ink storage body 30. It is. The ink storage body 30 is set on the upper part of the flat plate part 32 of the cartridge 31, and is surrounded by an upper wall frame 33.

In the pre-thermal processing stage, the cartridge 31 is temporarily fitted to the frame body to which the printed body 50 is attached at a separated position, as shown in FIG. For this temporary fitting, a small protrusion 35 is formed on the outside of the lower wall frame 34 of the cartridge 31, and the upper inner surface of the hanging wall 15 of the lower frame 12 is slightly overhanged inward. An inclined surface 36 is formed. The cartridge 31 is temporarily held in the position shown in FIG. 5 by pushing the small protrusion 35 of the cartridge 31 into this inclined surface 36.

At this time, the end 37 of the frame 10 on the back side extends further toward the back side than the end 38 of the cartridge 31. In other words, in the temporarily fitted state of FIG. 5, the lower end 38 of the cartridge 31 is located at a higher position than the lower end of the hanging wall 15 of the lower frame 12, and does not protrude as in the conventional case. Therefore, it is possible to prevent the cartridge 31 from being accidentally pushed in in the pre-thermal processing stage.

At the start of thermal processing, the cartridge 31 is pushed in by the attachment 40 as shown in FIG. 6, and enters the fully fitted state shown in FIGS. 4 and 7. When the fully fitted state is reached, the ink storage body 30 comes into close contact with the back surface of the printed body 50, and the ink gradually diffuses into the printed body 50. However, because thermal processing is completed in a short time, the inside of the processing machine is not contaminated by ink. Note that a recess 41 for receiving the attachment 40 is formed on the lower surface of the cartridge 31.

In order to guide the movement of the attachment 40 from the temporary fitting position to the final fitting position, a pair of hanging walls 15 of the lower frame 12 constituting the frame 10 are provided as shown in FIGS. 8 and 9. A guide groove 60 is formed. These guide grooves 60 are formed on the two surfaces on which the projections 18 described above are formed. On the other hand, the cartridge 31 is provided with a pair of protrusions 39 that fit into these guide grooves 60. With this configuration, the cartridge 31 can be smoothly pushed up to the final fitting position without rattling. FIG. 10 shows a state in which it has been pushed up to the final mating position.

When pushed up to the final mating position, as shown in FIG. It crosses over and is stably held in the final mating position.

As explained above, according to the stamp structure of the present invention, it is possible to prevent the cartridge 31 from being erroneously pushed in in the pre-process of thermal processing.
