At the same time, the colored light emitted from the color former is guided to the light receiving element by the half mirror, and the amount of the received light is amplified by the amplifier and notified by the notifying means.

[0013]

1 and 2 show one embodiment of the bill discriminating apparatus of the present invention. The bill discriminating apparatus of the present invention confirms whether or not the forgery prevention treatment is performed, and discriminates whether the bill is a genuine bill or a forged bill.

With reference to FIGS. 1 and 2, a genuine bill 3 has micro characters 1 printed at predetermined positions and a coloring agent 2 applied thereto. A discriminator using the bill discriminating device visually confirms the presence, shape, arrangement, etc. of the micro-characters 1, and irradiates the color-developing agent 2 on the stamp portion printed on the genuine bill 3 with light to develop the color. The presence / absence of the coloring agent 2 and the amount of coloring and the color tone are visually confirmed.
Authenticity is notified by electrically detecting the amount of color development and hue.

The micro character 1 printed on the genuine bill 3 is a very small character that cannot be visually confirmed to prevent forgery. As the color former 2, a fluorescent ink or the like that develops a color when irradiated with light is used. For example, in the genuine banknote bill 3, the color former 2 is mixed or applied to the seal portion printed with red ink.

The bill discriminating apparatus develops color by irradiating a convex first lens 4 for enlarging and transmitting the micro letter 1 and a radiating light 5a at a position facing the micro letter 1 of the genuine bill 3. The convex second lens 5 that transmits the colored light 2a of the coloring agent 2, the light source 13 such as an ultraviolet lamp that irradiates the colored light 2 with the irradiation light 5a, and the light receiving element 6 that receives the colored light 2a. Have

Further, the bill discriminating apparatus uses the colored light 2a as the second color.
A half mirror 7 composed of a semi-transparent mirror for projecting light into the lens 5 and the light receiving element 6 separately, and an amplifier 8 for converting the colored light 2a received by the light receiving element 6 into an electric signal for amplification. The coloring agent 2 is generated by the output signal output from the amplifier 8.
And an indicator 9 (notifying means) for notifying whether the unknown banknote 3a is true or false depending on the presence or absence, the amount of coloring, and the shade. In addition,
The unknown banknote 3a described here refers to a banknote in a state in which it cannot be judged with the naked eye whether it is a genuine banknote banknote 3 or a counterfeit banknote banknote.

Further, the bill discriminating apparatus detects the output signal from the amplifier 8 by detecting the presence / absence of the coloring agent 2, the amount of coloring and the shade, and the power supply 10 for supplying the necessary power to the light source 13 and the amplifier 8. It has a sound generator (notifying means) 11 such as a buzzer that informs the authenticity of the unknown bill 3a by sound depending on the presence or absence, and a power switch 12 that opens and closes the power supply to the light source 13 and the amplifier 8.

The second lens 5 expands the colored light 2a colored by the irradiation light 5a through the half mirror 7 and reflects it to the light receiving element 6 to project it. Light source 13
Lights up when power is supplied from the power supply device 10. The light receiving element 6 projects the colored light 2 a through the half mirror 7 and sends the amount of the colored light 2 a received to the amplifier 8. The amplifier 8 converts the colored light 2a received by the light receiving element 6 into an electric signal and amplifies it, and lights a display lamp (not shown) provided in the display 9 depending on the presence or absence of the colored light 2a. Similarly, the amplifier 8 drives the sound generator 11 by converting the colored light 2a received by the light receiving element 6 into an electric signal for amplification.

Further, in this bill discriminating apparatus, the first lens 4, the second lens 5, the display 9, the sound generator 11 and the power switch 12 are provided on one surface of the panel 14.

Next, a method for detecting whether the bill is a genuine bill 3 or a forged forged bill by using the bill discriminating device will be described below.

First, the unknown bill 3a is set so that the micro character 1 is located directly below the first lens 4.
At this time, immediately below the second lens 5 and the half mirror 7, the color former 2 applied to the seal portion is located. That is, the first and second lenses 4 and 5, and the half mirror 7 are pre-positioned at the positions facing the predetermined positions of the micro character 1 and the color developing agent 2, respectively.

A discriminator who tries to discriminate the authenticity of the unknown banknote 3a first looks into the first lens 4 as a first step and visually confirms whether or not the micro-character 1 is printed by the enlarged character. . At this time, when there is no micro character 1, it is determined that the bill is a counterfeit bill. In addition, when the micro character 1 is printed on the unknown banknote 3a, the first
Look into the lens 4 and determine whether or not the micro character 1 is correct. That is, the micro character 1 of the unknown bill 3a is visually checked to see if its shape, arrangement, and the like are correct. Thereby, the unknown banknote 3a is
It is visually determined whether the bill is a genuine bill 3 or a counterfeit forged bill.

Further, as a second step, the seal portion of the unknown banknote 3a is magnified and visually observed by the second lens 5 through the half mirror 7. In the second lens 5, when the irradiation light 5 a is applied to the coloring agent 2 by the light source 13, the coloring agent 2
When the colored light 2a from the original colored paper 2 is different from the original colored amount and shade of the genuine bill banknote 3 or the colored light 2a cannot be visually observed, it is determined to be a counterfeit banknote.

When the color-developing light 2a is emitted from the color-developing agent 2 when the color-developing agent 2 is irradiated with the irradiating light 5a, the true-color bill 3 has the same color-developing amount and shade as the true genuine bill 3. It is visually confirmed that it is the colored light 2a. That is, when the color former 2 is present and the color development amount and the color tone of the color light 2a of the color former 2 are correct, it is determined that the bill 3 is genuine. Coloring agent 2
If there is no light or the color of the genuine bill 3 is different from the colored light 2a, it is determined that the bill is a counterfeit bill.

Further, the colored light 2a that has been colored is reflected and bent by the half mirror 7 and received by the light receiving element 6, and the amount of received light is sent to the amplifier 8. The amplifier 8 amplifies the colored light received by the light receiving element 6 as an electric signal, and lights up the display lamp of the display 9 when it has the colored light 2a. Further, the sound generator 11 is driven by the power supply from the power supply device 10 based on the electric signal output from the amplifier 8.

The display 9 and the sound generator 11 are used when the colored light 2a received by the light receiving element 6 is absent or when the amount of colored light 2a is less than the original colored light 2a of the genuine bill 3. Alternatively, it may be lit or driven.

Since such a bill discriminating apparatus uses the colored light 2a of the coloring agent 2 of the genuine bill 3, it is installed at a place where a bill is handled and the unknown bill 3a is simply inserted into the bill discriminating device. It is immediately determined whether it is true or false. Therefore, in the case of a forged ticket banknote, the discriminator can quickly confirm and determine the person who brought the forged ticket banknote.

[0029]

As described above, according to the bill discriminating apparatus of the present invention, whether an unknown bill is a counterfeit bill or a genuine bill by only passing the unknown bill through the first and second lenses of the bill discriminating device. Can be quickly determined.

Further, a half mirror is provided above the color-developing agent, one of the colored lights divided into two systems by the half mirror is received by the light-receiving element, and the signal amplified by the amplifier is output to the notifying means to output the unknown bill. The truth of can be easily and quickly notified.

Therefore, unlike the conventional case, it takes no time to discriminate the authenticity of an unknown bill, and it is not necessary to request an expert to perform an appraisal, and it is possible to easily discriminate the authenticity without relying on an expert. There is.

Further, since the authenticity is immediately discriminated by simply passing the unknown banknote to the banknote discriminating device, the discriminator can quickly confirm the counterfeit banknote when it is a counterfeit banknote and bring in the counterfeit banknote. It becomes possible to determine the person.

Further, when the first lens, the second lens, and the notification means are provided on one surface of the panel, the first lens, the second lens, and the display can be easily viewed from one direction, and the sound generator can be easily seen. There is an advantage that the sound generated from the sound can be heard easily.
