Description

[Detailed description of the invention] Conventionally, a single flat rubber body has been used as an underlay for stamping, but it is only effective for stamping flat paper with a small number of sheets or thin books with a very small number of pages; for example, When used as a tally stamp for thick books, the elastic effect of the rubber body is not transmitted to the paper surface at all, and the effect of eliminating the level difference between the left and right pages caused by the binding section is not achieved, so the paper surface becomes uneven. I couldn't get the correct impression.

This design eliminates these shortcomings of the conventional single-rubber body and allows the correct stamp impression to be obtained without any restrictions on the thickness of the book. A two-lobed plane is formed, a protrusion is provided along the cut edge on the back side of the plane, and an elastic body is fixed to the plane with the same width.

The configuration of the present invention will be explained below with reference to drawings. 1 is a substrate;
5, 5 is an elastic body.

The substrate 1 is made of metal or plastic material, and has a cutout 2 in the center to form two planes 3, 3.
, 3, approximately triangular projections 4, 4 are formed along the lower edge of the cutout 2.

Note that it is preferable that the intervals between the cut-outs 2 are always kept open by about 2 mm, and the ends of the cut-outs 2 are preferably formed in a divergent shape.

The elastic bodies 5, 5 are thinly formed of natural rubber or synthetic rubber, and are fixed onto the flat surfaces 3, 3 of the substrate 1 with their widths matched.

Since it is constructed as described above, the method of use is to first insert two or several pages a through the wide-opening part of the slot 2, and push the protrusions 4 and 4 to the base of the page a. Then, open page a left and right, arrange the paper surface, and press ``print''.

Therefore, no matter how large the number of pages and thickness of the book's tally stamp, the bookmarking pad of the present invention can be used as a padding for one page on each side, or at most several pages on each side, so it can be used reliably. The elasticity of the elastic body acts to bring the paper surface and the stamp into close contact, and the protrusions 4.4 fill the gaps between pages, allowing the paper surface to be used horizontally, resulting in an accurate and clean stamp impression. It is something.

Further, in another embodiment shown in FIGS. 4 and 5, the substrate 1 in the embodiment shown in FIG. The entire periphery has a shallow curved rise resembling a spoon shape, and the interval between the cutouts 2 may be narrowed, and the entire curved rise is a little from the outer edge of the elastic body 5°5. It is even better to form it by folding it upwards.

As described above, when this rising part is pushed downward, the curved shape becomes downward, which is the opposite of flattened.Moreover, due to the bending tendency of the curved shape, it does not become a completely reversed shape of the original curved shape, so that the interruption 2 will be in an open state, insert page a there, and press protrusion 4,
4 to the base of page a, the curved portion can be returned to its original position.In addition to the above-mentioned effects, the page can be inserted more easily and the page can be held between the left and right sides.
