Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing improper use of a seal sticker attached to the surface of an adherend such as a bankbook for passbooks, and a passbook provided with the method for preventing improper use.

[0002]

2. Description of the Related Art In a bank passbook, a stamp field for stamping a depositor's registration stamp is provided on the cover, etc., and the imprinter stamped in this stamp column verifies and confirms the depositor himself. There is. By the way, it has been customary in the past to directly provide the stamp field directly on the surface of the passbook by printing. In that case, after imprinting the depositor's seal on the imprinted column, the imprint may remain exposed, but in general, to protect the imprint and prevent tampering, the imprinted surface is transparent. A protective film is attached.

However, only by covering the imprint with a protective film in this manner, the protective film can be easily peeled off by heating with an iron or a hair drier, for example, so that the imprint may be erased and tampered with. Yes, it is not sufficient as a tamper-proof measure. Therefore,
In order to deal with such a problem, for example, Jikho Sho 58-2
In the one described in Japanese Patent No. 0380, a printing layer made of an irreversible thermosensitive coloring ink is provided in a stamp field of a passbook, the surface thereof is masked with a transparent seal film, and the transparent seal film is peeled by heating with an iron or the like. In such a case, it is possible to see at a glance that the irreversible thermosensitive coloring ink has developed color and has been tampered with.

However, in the conventional ones including those disclosed in the above publications, generally, the stamp field is directly printed on the surface of the deposit passbook, so that the depositor uses the seal stamp each time the passbook is updated. It was necessary to bring it to the office, and the bank also had to perform the collation confirmation work of the imprint every time it was updated, and both sides were complicated and troublesome. Therefore, as a solution to such a problem, a seal imprint sticker in which a seal stamp column is printed and which can be transferred to a new passbook when the passbook is updated is disclosed in, for example, Jikkei 3-645.
No. 1 publication. In the publication described in the publication, a seal imprint provided with a seal part for imprinting a seal on the surface and a part for entering a confirmation code for distinguishing from other seal imprints, and affixed and fixed on the surface of this seal imprint A transparent protective film, a non-adhesive part for peeling, and a slit for breakage at the time of peeling are formed respectively, and an appropriate color that is transparent is applied. When the passbook is to be renewed with the covering film that is attached and fixed, and when updating the passbook, after peeling off the covering film by holding the non-adhesive part, the seal imprint with the protective film attached is used. Peel it off the surface of the passbook, attach it to a new passbook, and then attach and fix a new covering film on top of it to reduce the complexity of renewal as described above and to prevent damage when peeling off the covering film. So as to prevent fraud such as imprint tampering by the slit.

[0005]

However, even in the one disclosed in Japanese Utility Model Publication No. 3-6451, the covering film (cover film) is easily peeled off when heated with an iron or the like, so that the surface of the passbook is damaged. There is a risk that the cover film may be peeled off without permission, and there is a problem that the seal cannot be discriminated even if the seal imprint seal is improperly replaced. Therefore, it is conceivable to provide a printing layer on the surface of the passbook with an irreversible thermosensitive coloring ink as described in JP-B-58-20380, but in that case, since an expensive ink is used, the cost is increased, In addition, the manufacturing process becomes complicated.

The present invention has been made in view of the above problems, and a method for preventing improper use of a seal sticker capable of enhancing the effect of suppressing an improper replacement of the seal sticker by a simple method, and the same. The purpose is to obtain a passbook with a method of preventing unauthorized use.

[0007]

A method for preventing unauthorized use of a marking seal according to the present invention is intended to prevent unauthorized use of a marking seal which has a marking portion and which is covered with a cover film and is removably attached and fixed to an adherend. The method is characterized in that the ink is bleached or discolored by heat so as to straddle the adherend and the cover film, and a tally mark is applied.

The passbook which has been subjected to the above unauthorized use prevention method is a passbook in which a seal sticker is adhered and fixed to a predetermined portion by a cover film, and the passbook is covered with the cover film by heat so as to straddle it. It is characterized in that it is provided with a tally using an ink that fades or changes color.

[0009]

[Function] When a passbook or the like is created, a seal sticker with a depositor's registration stamp is placed at a predetermined position on the surface of the adherend such as the passbook, and a cover film is put over the sticker and fixed. A mark is formed by using an ink that is discolored or discolored by heat so as to straddle the adherend and the cover film. By doing this, it is possible to determine when the cover film is illegally peeled off and replaced with a new cover film, and the cover film is temporarily peeled off by using a heating means such as an iron and the cover film is again removed. Even when affixed, it is possible to determine at a glance that the ink of the tally mark has been tampered with because it has faded or discolored.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a passbook according to an embodiment of the present invention, and FIG. 2 is a sectional view of a cover film attaching portion in the same embodiment.

In this embodiment, the cover film 1
Is for covering the surface of the stamp seal 3 attached at a predetermined position on the cover of the bankbook 2 used in a bank, and is formed by cutting a biaxially stretched polyester film into a substantially rectangular shape. ing. On the back surface of the cover film 1, a gluing part 4 in which an adhesive is applied in a predetermined width over the entire circumference except for the upper part (knob part) of the short side on one side.
(Outer portion of the one-dot chain line in FIG. 1) is formed, and a glue stop portion (the same inner portion) 5 to which no adhesive is applied is formed in a portion surrounded by the glue portion 4. Further, the cover film 1 is provided with a release paper temporarily attached to the gluing portion 4 thereof for use.

The marking seal 3 is formed by sticking a transparent transparent laminate seal 7 on the surface of a paper base seal 6 made of paper. Here, the base body seal 6 is provided with fields such as a depositor's registration mark and a bank side verification mark by printing on the front surface, and a weak adhesive is applied on the back surface. Then, after stamping or the like on a predetermined column of the substrate seal 6, the laminate seal 7 is attached to the surface thereof. A pressure sensitive adhesive is applied to the surface of the laminate seal 7 on the side of the base seal 6, and a release paper is applied to the coated surface so that the laminate seal 7 adheres to the surface of the base seal 6 only on one side before use. It is temporarily attached. And
The base seal 6, the laminate seal 7 and the release paper interposed in between are used as a set of three sheets with the back surface of the base seal 6 temporarily attached to the surface of the mount formed by the release paper. ..

Then, when the cover film 1 is attached and fixed so as to cover the seal stamp affixed to the predetermined portion of the cover of the passbook 2, the upper and lower edges of the cover film 1 are fixed as shown in FIG. At the central portions of the above, tally marks 8 are stamped so as to straddle the cover film 1 and the passbook 2. In that case, as a stamp ink, an ink containing a colorant having a heat-sensitive change property that discolors (discolors) or discolors at a temperature of about 60 ° C. to 120 ° C., for example, one that uses heat blackening with phenolphthalein and a leuco dye Etc. are used.

With the above-described structure, when a new account is opened, the bank side first seals the base body seal on the marking portion provided at a predetermined position on the cover of the passbook 2. 6 is placed and once attached, the base seal 6
After registering the depositor's registration mark and the bank's collation mark in the stamp field on the front side of the above, and after filling in the prescribed items, the release paper on the back side of the laminate seal 7 is peeled off and the laminate seal 7 is attached to the surface of the base seal 6. To do.

Next, the cover film 1 is peeled off from the release paper, and the cover film 1 is stuck and fixed on the surface of the passbook 2 so as to cover the surface of the marking seal 3. When the cover film 1 is attached, the surface of the marking sticker 3 is brought into contact with the glue stopping portion 5 of the cover film 1. After that, the stamp 8 as described above is used to make the tally mark 8 at a predetermined position with the collation mark on the bank side.

According to this embodiment, when the cover film 1 is peeled off and replaced with a new cover film for the purpose of tampering with the imprint of the seal 3, the tally marks 8,
Since half of 8 is missing, it can be seen at a glance that it has been tampered with. Also, when the cover film 1 is heated with, for example, an iron or a dryer to be temporarily peeled from the passbook 2 and the cover film is attached again, the tally marks 8,
Since the ink of No. 8 is discolored or discolored, it can be determined at a glance that it has been tampered with.

When the bankbook 2 has been used and is to be renewed, the edge of the glue-fixing portion 5 (knob portion) formed on one side (right side) of the cover film 1 on the bank side is renewed.
The cover film 1 is peeled off from the surface of the passbook 2 by pinching, and the stamp seal 3 including the base seal 6 and the laminate seal 7 is taken out. Then, this is attached to a new passbook and its surface is covered with a new cover film.
In that case, the seal 3 can be taken out quickly and easily by peeling off the cover film 1 while holding the knob portion.
