Abstract

PROBLEM TO BE SOLVED: To furthermore improve the reliability by certainly ejecting a divided paper money when it is inserted. SOLUTION: This device is parallelly provided with a light emitting element 4a of near infrared rays and red LED 5a to emit light from both to an inserted paper money A to compare data obtained by light-receiving its reflection or transmitting light with a true one. In this case, the light emitting element 4a of near infrared rays and red LED 5 are parallelly arranged crossing the carrying direction of the paper money A. In addition the light emitting element 4a of near infrared rays is arranged on the center line of the carrying direction of the paper money A. In addition, the red LED 5a is arranged on the center line of the carrying direction of the paper money A.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill authenticity determination device, and more particularly to an improvement of a bill authenticity determination device attached to an automatic vending machine, an automatic lending machine, a money changer or the like.

[0002]

2. Description of the Related Art Conventionally, as a device or method for judging the authenticity of a bill inserted in a device, the magnetism contained in the bill is detected, and the wavelength and waveform data obtained by an optical system are compared with those of the genuine one. Things are being done.

Recently, in the case of magnetic detection, forgery can easily be made and it is possible to bypass the check. Therefore, many optical systems are used, and in that case, in addition to a single sensor, different wavelengths, for example, Near infrared and red LE
The authenticity is determined by using the two light-emitting elements D and calculating the obtained data respectively.

When the two light emitting elements of near infrared ray and red LED are used, they are generally arranged as shown in FIG. That is, in FIG. 2, reference numeral 1 denotes an insertion portion of the banknote A, and rollers 2 and 2 for introducing the inserted banknote A into the inside of the insertion portion 1 are exposed from the opening, and subsequently, Belts 3 and 3 for loading are provided.

A near-infrared light emitting element 4 and a red LED 5 are arranged side by side on the center line of the bill A in the conveying direction.
A light receiving element (not shown) that obtains data by reflecting or transmitting the irradiation light from the two light emitting elements 4 and 5 is provided. This near-infrared light emitting element 4 and red L
The provision of the ED5 on the center line in the banknote conveyance direction is to sequentially scan the banknote A to obtain data, calculate the data, and compare the data with the authentic data.

[0006]

However, the insertion portion 1 is formed to be slightly wider than the bill A in order to facilitate the work of inserting the bill A. Therefore, the bill A with the near-infrared light emitting element 4 and the red LED 5
The scanning portion of can deal with the bill A even when the bill A is biased to the insertion portion 1.
Therefore, the banknote A is divided into two along the insertion direction,
If it is inserted, the center portion of the banknote A, which has been offset, is scanned, and there is a possibility that the banknote A may be determined as an authentic banknote.

[0007]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to the actual situation and problems of the above-mentioned conventional techniques, and it is possible to eliminate such problems and to always reject a divided bill when inserting it. It is an object of the present invention to provide a bill authenticity determination device which is capable of further improving reliability.

[0008]

In order to achieve this object, the bill authenticity judging device according to the present invention has a near-infrared light emitting element and a red LED arranged in parallel, and the above-mentioned bill is inserted into the bill. In a bill authenticity determination device that radiates light from both and receives the reflected or transmitted light and compares the obtained data with the authentic one, in the bill conveyance of the near infrared light emitting element and the red LED described above. Characterized in that they are arranged side by side so as to intersect the direction, and that a near-infrared light emitting element and a red LED are arranged side by side across the center line of the banknote transport direction, the banknote transport direction It is characterized in that a near-infrared light-emitting element is arranged on the center line of, and a red LED is arranged on the center line in the banknote transport direction.

[0009]

With such a structure, the near-infrared light emitting element and the red LED take data over a certain width of the bill, and when a divided bill or the like is inserted, at least one of the light emitting elements is inserted. It becomes impossible to take data from.

[0010]

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a plan view showing a bill authenticity determination device embodying the present invention. The same parts as those in the conventional example are designated by the same reference numerals and detailed description thereof will be omitted.

First, in the present embodiment, the near-infrared light emitting element 4a and the red LED 5a are arranged side by side in a position intersecting the conveyance direction of the banknote A, and also in an orthogonal arrangement. In this case, The near-infrared light emitting element 4a and the red LED 5a may straddle the center line of the banknote A in the transport direction, or one of the near-infrared light emitting element 4a and the red LED 5a may be disposed on the center line.

[0012]

The bill authenticity judging device according to the present invention is constructed as described above. Therefore, when the bill is divided and inserted, the data from one of the light emitting elements is not obtained, and it is inevitably rejected as a counterfeit bill.
Further, since the authenticity can be finely determined without being particularly inferior to the data obtained from the light emitting elements which are conventionally arranged in columns, the reliability as a device is further improved. There is.
