JP2001325639A - Simplified paper money identifier - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve a problem that a portable paper money identifier is made large, expensive and unsuitable for carrying since truth-false is identified by detecting the magnetic ink printing part, fluorescent ink part and fine printing part of an identification element. SOLUTION: Concerning the truth/false identification element of the simplified paper money identifier, truth/false is identified by collating the right position and right form of a watermark pattern and a watermark on a paper money with a master plate. Besides, a light emitting diode is used for a light source.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple bill validator for judging whether bills are authentic based on the position and shape of a watermark pattern and a watermark mark.

[0002]

2. Description of the Related Art Conventional portable type appraisers perform detection by detecting a magnetic ink printing section, a fluorescent ink printing section, and a fine printing section. Also, a fluorescent lamp was used as a light source.

[0003]

SUMMARY OF THE INVENTION The aforementioned conventional identifier is
Since the magnetic ink printing section, the fluorescent ink printing section, and the fine printing section are used for the appraisal element, the authenticity appraisal is very delicate, requires skill, and requires a long time for appraisal. Furthermore, since each of the above-mentioned identification elements requires a detector and is expensive, and a fluorescent lamp is used as a light source, the size is increased and a dedicated power supply is required, which poses a problem in carrying.

[0004]

In the present invention, the appraisal element is narrowed down to a watermark pattern and a watermark mark, and light is emitted from the front or back of the bills by a light source of a light emitting diode to grasp the entire pattern. Furthermore, in order to improve the accuracy of the authenticity judgment, it is collated with the master plate, and the authenticity judgment is performed instantaneously.

[0005] A plurality of master plates are prepared and stored in accordance with the type of banknotes, and one of the master plates is required for appraisal.
Insert the sheet into the plate holder and fix it in a certain position,
At the same time, it is checked against the bills fixed at a fixed position to confirm that the watermark pattern and the watermark mark of the bills are present at the correct position and in the correct shape.

A light-emitting diode illuminating device in which the light-path direction of a light-emitting diode is arranged in parallel with banknotes ensures the light-path length of the light-emitting diode, reduces the size and weight of an appraiser, incorporates a battery, and facilitates carrying. It is.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a side perspective view of the embodiment. 2 and 3, (10) is a banknote, (3) is a light receiving plate, (4) is a light emitting diode printed board, and a plurality of light emitting diodes (11) are provided on the surface of the banknote (10).
And the optical path direction (L) of the light emitting diode (11)
Are also arranged in parallel. A reflecting mirror (5), a reflecting mirror (6) and a reflecting mirror (13) are mounted on the light emitting diode printed board (4). As shown in FIG. 8, a conventional light emitting diode lighting device has a light emitting diode (1).
The optical path of 1) is arranged in a direction orthogonal to the bills (10). In addition, one or two light diffusion plates (12) are provided between the light emitting diode (11) and the bills (10).

In the above-mentioned light emitting diode lighting device, the light path length of the light emitting diode (11) and the bills (10) needs to be about 50 mm or more in order to obtain an effective luminance and an illuminating area. Become In addition, the light diffusion plate (1
2) The surface is subjected to diffusion processing by a mechanical method,
The fine scratches are reflected on the surface of the banknotes (10) as a pattern by receiving the light of the light emitting diode (11), and overlap with the watermark pattern, the watermark mark, etc., which are most required by the present discriminator, making the discrimination difficult. .

Therefore, in the present invention, first, the distance between the banknotes (10) and the light emitting diode (11) in FIG. 3 is reduced, and the direction of the optical path (L) of the light emitting diode (11) is changed in order to reduce the size. A reflecting mirror (5) arranged parallel to the surface of the bills (10) and inclined at the most efficient angle in the traveling direction of the optical path (L) and a reflecting mirror (6) shown in FIG.
To irradiate the light of the light emitting diode (11) to the light receiving plate (3). Furthermore, as shown in FIG. 4, three reflecting mirrors (13) are provided on the surface of the light emitting diode printed circuit board (4) where the light emitting diodes (11) are not arranged. The light receiving plate (3) is made of a translucent milky white resin that has not been subjected to light diffusion processing so that the brightness of light becomes uniform, and the transparent pattern and the watermark mark of the banknote (10) are clearly seen through. To make things possible. With the configuration as described above, light from the light emitting diode (11) is effectively radiated to the light receiving plate (3), and illumination unevenness is very small. A lighting device is easily obtained.

The operation of the above embodiment will be described. First, when the power switch (9) is turned on in FIG. 1, all of the light emitting diodes (11) are turned on. In FIG. 2, bills (10) to be examined are placed on the surface of the light receiving plate (3), and the bills (2) are abutted in the A and B directions of the abutment plate (2) to be set at a fixed position. In this state, the watermark pattern and the watermark mark of the banknote (10) are already in a state that can be clearly seen. Next, the master plate (15) indicated with the same display as the object to be measured is extracted from the master plate storage box (14). FIG. 5 shows an example of the master plate (15).
The material of the master plate (15) is a transparent film having a thickness of about 0.2 mm, and elements necessary for the identification are written in the correct positions on the film. In addition, the corresponding master plate (1) is stored in the master plate storage box (14).
The display is written at positions slightly shifted from each other so that 5) can be easily selected and extracted.

FIG. 6 shows the plate holder (16).
The plate holder (16) is located between the cover (18) and the housing (1), and is provided at the same fulcrum as the cover (18) in FIG. The central portion of the plate holder (16) is hollowed out in substantially the same area as the light receiving plate (3). Further, positioning stoppers (17) are provided at three places so that the master plate (15) and the bills (10) are correctly aligned when they overlap. By setting the master plate (15), depressing the plate holder (16), and overlapping the previously set bills (10), the watermark pattern and the watermark mark are present in the correct position and in the correct shape. Can be instantaneously and easily determined by visually confirming.

[0012]

As has been apparent from the above embodiments, in authenticity judgment of banknotes, authenticity judgment is made by confirming that the watermark pattern of the judgment element and the watermark mark are present in the correct position and in the correct form. Made it possible to do so. Therefore, detectors and a detection circuit necessary for obtaining a large number of identification elements are not required, so that miniaturization and cost reduction can be easily achieved.
Furthermore, by using a light emitting diode as a light source, the size can be reduced, and heat generation from the light source can be reduced, so that the device can be used for a long time. At least at a counter at a bank, a store, or the like that directly handles bills, traveler's checks, gift certificates, and the like, it is easy to provide a quick, easy, and low-cost appraisal apparatus.
