Definitions
- the light emitting element is configured to individually emit a plurality of sensing lights (near infrared light, visible light) in different wavelength bands, and the light receiving element is different from the light emitting element. It is configured to be able to independently receive light generated from the surface configuration of the object when the sensing light in the wavelength band is individually emitted. Then, the identification sensor receives light generated from the surface configuration of the object.
- a calculation determining unit 12 that performs a calculation process on the identification signal output from the light receiving element and determines whether the identification signal is within a predetermined allowable range.
- the arrangement interval and the number of the identification sensors 2 are arbitrarily set according to the shape and position of the characteristic portion of the banknote 4, and the arrangement interval and the number of the identification sensors 2 are not particularly limited.
- the characteristic portion of the bill 4 as an object refers to a portion that is effective for specifying or discriminating the object (bill) 4.
- the identification sensor 2 Since the identification sensor 2 is provided with the arithmetic determination unit 12, the identification signal output from the light receiving element 10 is subjected to predetermined arithmetic processing in the arithmetic determination unit 12, and the identification signal is output to the predetermined signal. Is determined to be within the allowable range.
- the sensor unit 14 has a substantially rectangular shape in the drawing, but may have any other shape as long as the shape does not hinder scanning.
- the sensor unit 14 having such a shape has an optical path opening 14a formed in a part thereof, and the surface of the sensor unit 14 excluding the optical path opening 14a is subjected to light shielding processing. I have.
- a light-shielding portion 18 is formed (integrally formed) on the surface of the sensor unit 14 of the present embodiment excluding the optical path opening 14a.
- any other light-shielding process may be applied to other configurations as long as external light does not enter the sensor unit 14. It is possible.
- the sensor unit 14 is integrally formed with a light-collecting optical system (16a, 16b, 16c) by a transparent member (eg, plastic such as transparent resin, transparent glass, etc.).
- the sensor unit 14 is installed facing the condensing optical system (16a, 16b, 16c) Specifically, the sensor unit 14 is provided with a hollow portion 20 formed by partially hollowing out the inside. and, the light emitter (8 a ⁇ , 8b) and the photoreceptor 1 0 opposed to being placed in the cavity 2 0 on the condensing optical (16a, 16b, 16c).
- the arithmetic determination unit 12 performs predetermined arithmetic processing on the identification signal output from the photoreceptor 10 and determines whether or not the identification signal is within a predetermined allowable range. That is, it is determined whether or not the sample data is in an area between the maximum line Ml and the minimum line M2 of the sample data as shown in FIG. Specifically, if the identification signal from the photoreceptor 10 ′ is plotted along the area (tolerance) between the maximum line Ml and the minimum line M2, the banknote 4 is genuine. If the identification signal from the photoreceptor 10 ′ is not plotted along the area (allowable range) between the maximum line Ml and the minimum line M2, the bill 4 Is determined to be counterfeit.
- the same sensing light (scanning light) as that of the first embodiment is obtained by using commercially available inexpensive luminous bodies (8a ', 8b') and the photoreceptor 10. Since it is possible to obtain sensing light with a wide sensing area in the direction perpendicular to the direction S1, it is possible to simplify the sensor configuration and achieve a significant reduction in manufacturing cost.
- the other effects are the same as the effects of the first embodiment, and the description is omitted.
- the banknote 4 is applied as the target object.
- the present invention is not limited to this.
- the surface configuration in this case is a pattern-printed integrated circuit. According to such a configuration, since the accuracy of the integrated circuit can be determined, it is possible to improve the product yield.
- the luminous body emits a plurality of sensing light (near infrared light Ll, visible light L2) in different wavelength bands from each other (in the present embodiment, Are composed of two) light emitting sections 8a 'and 8b, but the present invention is not limited to this.
- sensing light near It is also possible to use a single luminous body 8 ′ that can individually emit the infrared light L 1 and the visible light L 2) (alternately emit light at a predetermined timing).
- the oscillation wavelength of the light emitting body 8 ′ is changed. Varying methods can be applied.
- the example of the identification sensor 2 using the reflected light (R1, R2) is shown, but the present invention is not limited to this.
- FIG. As shown in (b), the identification sensor 2 using transmitted light can be used.
- the pair of identification sensors 2 are arranged to face each other with the object 4 interposed therebetween, the light receiving function of the light receiver 10 ′ of one of the identification sensors 2 is stopped, and the light emitter 8 ′ (light emission) of the other identification sensor 2 is stopped.
- the light emission function of the sections 8a 'and 8b') is stopped.
- the sensing light (near-infrared light, visible light) from the light emitter 8 ′ (light emitting portion 8 a ⁇ , 8 lT) of one identification sensor 2 passes through the object 4, and then the other identification sensor 2 The light is received by the photoreceptor 10.
- the object 4 is limited to an object having light transmittance.
- the condenser lens portion 16c has a flat lens surface in the direction along the scanning direction S1 (see FIG. 3). May be convexly curved toward the photoreceptor 10 in a direction along the scanning direction S1.
- the wide light (the light (R1, R2) generated from the surface configuration of the bill 4) incident through the optical path opening 14a is received by the condenser lens 16c without leakage.
- the light is focused toward the body 10 ′ and condensed on the light receiving surface (not shown) of the light receiver 10 ′.
- the authenticity and the authenticity of the object can be improved without being affected by the displacement and the like of the surface configuration of the object. Accuracy and the like can be accurately determined. Furthermore, since the sensing is performed by individually emitting a plurality of sensing lights in different wavelength bands, the surface configuration of the object can be determined with high discriminating power.
