Description

[Detailed description of the invention] (Field of industrial application) This invention forms a large number of cup-shaped bulging dots on a thin plate-like substrate made of a soft elastic material, removes predetermined bulging dots, and removes the remaining dots. This invention relates to a dot type format in which a mark is formed by the protruding end surface of a predetermined bulge dot by inverting the bulge dot.

(Prior Art) In conventional formatting, a stamp is formed by directly stamping the end face of a bar made of a hard material or the surface of a plate made of a soft material.

(Problems to be solved by the invention) The conventional method described above requires a chisel to form the stamp and a mold for molding, so it requires skill to manufacture and has the disadvantage of being effective. It was hot.

Furthermore, once a stamp is formed, it cannot be changed or corrected, which has the disadvantage that its range of use is limited.

The object of the present invention is to obtain a new dot format that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides the following:
forming a large number of cup-shaped bulging dots that bulge out in the thickness direction of one of the flesh portions of the substrate, and inverting the remaining bulging dots in the other thickness direction with respect to a predetermined bulging dot; A seal is formed by the protruding end surface of the predetermined bulged dot.

(Function) Since the present invention has the above-mentioned configuration, when the remaining bulging dots are reversely bent upward from the lower surface side of the substrate with respect to the predetermined bulging dots corresponding to the stamp shape, these bulging dots can be The lower end surface of the bulging dot is recessed relative to the lower end surface of a predetermined bulging dot.

As a result, the lower end surface of the predetermined bulging dot.
In other words, the protruding end surface forms a stamp shape.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the drawings, FIG. 1 is a partially sectional side view showing an embodiment of the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a partially enlarged sectional view of essential parts thereof, and FIG. 4 is a bottom view thereof. FIG. 5 is a partially enlarged sectional view showing the stamp formation state of the above-mentioned essential parts, FIG. 6 is an enlarged sectional view of the essential parts of FIG. 1, and FIG. 7 is a main part equivalent to FIG. 6 showing another embodiment. FIG.

In Figures 1 and 2, reference numeral 1 denotes a card-shaped body made of a relatively hard and flexible plastic material, and a movable base that bends upward into a truncated cone shape on the right side of the body 1. form 2.

The movable table 2 has a thick head 2a to increase bending rigidity, and a thin standing wall 2b to facilitate bending and stretching in the vertical direction.
The head 2a is supported vertically movably, and the head 2a
is always elastically biased upward.

A disk-shaped substrate 4, which is engaged with a cylindrical holding frame 3, is fixed to the lower surface of the head 2a.

As shown in FIGS. 3 to 5, the substrate 4 includes:
It is formed into a thin plate shape from a porous plastic material that is soft and highly elastic, and has bulging dots 5 on almost the entire surface.
It is formed by forming a large number of.

The bulging dot 5 is formed by bulging the flesh part of the substrate 4 downward into a conical shape, and forming a columnar pressure body 5a having a circular or polygonal cross section at the bottom of the bulging.

Peripheral wall 5b of the bulge supporting the pressurizing body 5a
is formed thin to facilitate bending and stretching in the vertical direction, and its bulging shape is similar to the reference surface 4a of the substrate 4.
It is set so that a snap action occurs when bending upward and downward with the center at the center.

In addition, at the initial stage such as at the time of shipment, each bulging dot 5 is made to protrude downward from the substrate 4 as shown in FIG. 3, and the lower surfaces of the pressurizing bodies 5a are all kept at the same level.

When forming a seal, a transparent plastic film (not shown) on which a seal such as a typeface or a figure is printed is pasted on the stamping surface, that is, the lower surface of the substrate 4, and a bulging dot corresponding to the seal is formed. 5
The bulging dots 5-2 other than -1 are pushed in one by one using a pushing tool 10 formed in the shape of a pin with a small diameter, as shown in FIG. 5, and turned upward.

Then, the pressurizing body 5a of the bulging dot 5-2
is moved and held upward by the snap action of the peripheral wall 5b, and the lower surface of the pressing body 5a of the bulging dot 5-1, which is in the initial position, forms the impression surface.

Next, as shown in the sixth position, adhesive 6 is filled into the upper part of the substrate 4 to integrally fix each bulging dot 5 to the substrate 4 and the holding frame 3 side.

As a result, the bulging dot 5- which has become the initial position
The lower surface of 1 will form the stamp surface.

FIG. 7 shows another embodiment.

In this case, the holding frame 7 is formed into an inverted shallow container shape, and the bottom of the holding frame 7 has convex portions 7a that abut against the upper surface of the substrate 4 between the aforementioned bulged dots 5.
and a large number of recesses 7b corresponding to each bulging dot 5 are formed.

Then, the upper surface of the substrate 4 is supported between the bulging dots 5 by the convex portions 7a, and the bulging dots 5-2, which have been inverted upward, are fitted into the recessed portions 7b.

This one has a bulging dot 5-1 that protrudes downward.
A recess 7b is present at the bottom of the holding frame 7 corresponding to the bulge dot 5- which forms the stamp.
1 exists in large numbers, the load applied to one bulging dot 5-1 during stamping becomes smaller.
These will no longer be flipped upwards during stamping.

Incidentally, in the present invention, the substrate 4 on which the bulging dots 5 are formed may be attached to the lower surface of a rod-shaped body, thereby forming a rod-shaped size. Further, a stamp may be formed on the end surface side of the upwardly recessed bulging dot 5-2.

(Effects of the invention) As is clear from the above explanation, the present invention arranges a large number of bulging dots in parallel on a plate-shaped substrate, and makes a part of the dots deviate in the thickness direction of the substrate for printing. Since the shape is formed, no special tools or techniques are required to form the stamp. Moreover, it becomes possible to easily change or modify the shape of the stamp midway through the process.

Therefore, the present invention has the advantage that it is inexpensive, allows amateurs such as users to easily create a size that suits their taste, and can be used for various purposes such as business use and toys. .
