JPS5820380Y2 - passbook - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a bank account book, a postal account account book, and other passbooks that prevent the number of associates from being written.

Generally, in the case of a bank deposit passbook, etc., a stamp field is provided on the endpaper of the front cover, and the depositor's registration seal is stamped on the stamp field, and a transparent film is heat-adhered on top of it, so that the vermilion can be easily erased and a number of pages placed. It is configured in such a way that it cannot be done.

However, since the transparent film pasted on the stamp area can be easily peeled off by heating with an iron or the like, the number placement prevention is not 100% effective.

Furthermore, since the magnetic tape currently attached to bankbooks can be easily peeled off in the same way, it is impossible to prevent the tape from being replaced.

As a result of research to solve the problem of slanting, the inventor of the present invention printed irreversible heat-sensitive coloring ink on the stamp area and/or magnetic tape pasting area, and when the transparent seal film and/or magnetic tape was peeled off, it became heat sensitive. We have discovered that by configuring the scales so that the colored ink develops color, the scales can completely prevent the problem of color.

The present invention was made based on such knowledge.

That is, the gist of the present invention is a passbook having a stamping field and/or a magnetic tape pasting field, in which irreversible thermosensitive coloring ink is printed on the stamping field and/or the magnetic tape pasting field.

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

FIG. 1 shows a first embodiment of the invention.

A printing layer 2 of irreversible thermosensitive coloring ink is provided on a stamp field 1 on the end face of the cover of the passbook.

The depositor's registration seal is stamped on the stamp field 1, a transparent seal film 2' is pasted, and the stamped area is masked with the transparent seal film.

In the case of the passbook of the present invention described above, when the transparent sealing film is peeled off by heating with an iron or the like, and the vermilion is erased, the irreversible heat-sensitive coloring ink printed on the stamp area develops color. However, since it becomes possible to see at a glance that the number has been placed, unauthorized use of the device passbook can be completely prevented.

FIG. 2 shows a second embodiment of the invention.

A printing layer 2 of irreversible thermosensitive coloring ink is provided in a magnetic tape pasting field 3 on the cover of the bankbook, and a magnetic tape 4 is pasted thereon.

Therefore, in the case of the passbook of the present invention, the magnetic tape is peeled off by heating with an iron, etc., and another magnetic tape is pasted in its place. The heat-sensitive colored ink develops color, making it possible to see at a glance that a number-setting passbook has been placed, thereby completely preventing unauthorized use of the number-setting passbook.

In the present invention described above, it is desirable that the irreversible thermosensitive coloring ink is one that normally exhibits white color and develops color when heated to 90 to 100°C, such as commercially available thermostatic ink such as Teika Sangyo thermochromic ink, or Oriental thermochromic ink. A temperature-indicating ink prepared by mixing a commercially available thermo-indicating pigment such as Giken's thermo-indicating pigment thermal color can be used.

As described above, the passbook of the present invention is a passbook that has a seal area and/or a magnetic tape pasting area, and the irreversible thermosensitive coloring ink is printed on the seal area and/or the magnetic tape pasting area. It is possible to completely prevent placing multiple stamps or changing or changing the magnetic tape.
