The regulation unit 220 abuts the bill BN inserted into the slit portion 30 to regulate the insertion amount of the bill BN. With such an embodiment, when the bill BN is slid in the slit portion 30, it is possible to realize a state in which the bill BN having a substantially constant width is always inserted into the slit portion 30. Therefore, the position where the security element of the banknote BN is provided can be more reliably scanned by the optical sensor, and the accuracy of authenticity identification of the banknote BN can be improved.

The position of the regulating portion 220 can be adjusted, and the slit depth D, which is the distance until the bill BN inserted in the slit portion 30 comes into contact with the regulating portion 220, can be changed according to the position of the regulating portion 220. .. With such an embodiment, the banknote BN can be inserted into the slit portion 30 to the optimum position of the banknote BN according to the type of the banknote BN. The slit depth D is equal to the insertion amount of the bill BN inserted until it comes into contact with the regulation portion 220.

The attachment 20 including the first guide portion 211 is movable with respect to the housing 100 forming the second guide portion 111, and the regulation portion 220 is movable with respect to the housing 100, and the attachment 20 is movable.

With such an embodiment, the regulation unit 220 can be adjusted to an appropriate position according to the type of banknote BN, etc., and the versatility of the authenticity identification device 1 can be enhanced (the range of application can be expanded). it can.

More specifically, as shown in FIG. 5, the bottom surface 110 of the housing 100 has a plurality of recesses 112 provided on the rear surface 160 side at a predetermined pitch. Further, as shown in FIG. 6, the first guide portion 211 of the attachment 20 has a protrusion 212 in a region sandwiched between the pair of restricting portions 220. With such an embodiment, the protrusion 212 of the attachment 20 can be fitted into any of the plurality of recesses 112 included in the housing 100, and the position of the attachment 20 that slides with respect to the housing 100 can be fixed. .. Further, by arranging the plurality of recesses 112 at a predetermined pitch, the attachment 20 can be slid with respect to the housing 100 at a predetermined pitch, and the regulating portion 220 can be moved at a predetermined pitch. Become.

In the slit depth D, the maximum value of the distance from the optical sensor 102 (detection unit) described later to the regulation unit 220 is preferably half the length of the short side of the bill BN. With such an embodiment, the characteristics of the banknote BN can be detected up to the center line of the banknote BN by inserting the banknote BN into the slit portion 30 from one long side of the banknote BN. By inserting the bill BN into the slit portion 30 from each of one long side and the other long side of the BN and detecting the characteristics of the bill BN, it is possible to detect the characteristics of the entire surface of the bill BN. Become. Further, this eliminates the need to make the housing 100 larger than necessary, and the housing 100 can be miniaturized. The distance from the detection unit to the regulation unit 220 is the point that the detection unit actually detects the characteristics of the bill BM in a state where the bill BN is inserted into the slit portion 30 so as to abut the regulation portion 220 ( It may be the center of the area) to the end of the banknote BN on the regulation part 220 side. In the case of the optical sensor 102, the distance from the optical sensor 102 to the regulation portion 220 is the end portion of the bill BN on the regulation portion 220 side when the bill BN is inserted into the slit portion 30 so as to abut the regulation portion 220. It may be the distance from the point obtained by projecting the center of the optical sensor 102 vertically onto the bill surface.

As shown in FIG. 7, the slit depth D is set according to the type of bill BN. Here, the slit depth D is the sum of the distance D1 from the front surface 150 to the optical sensor 102 and the distance D2 from the optical sensor 102 to the regulation unit 220, and the distance D2 from the optical sensor 102 to the regulation unit 220 is changed. , The slit depth D shall be changed. For example, FIG. 7A shows a case where the distance D2 from the optical sensor 102 to the regulation unit 220 is set to d1 so as to correspond to the bill BNa. Further, FIG. 7B shows a case where the distance D2 from the optical sensor 102 to the regulation unit 220 is set to d2 (d2> d1) so as to correspond to the bill BNb. Further, FIG. 7C shows a case where the distance D2 from the optical sensor 102 to the regulation unit 220 is set to d3 (d3> d2) so as to correspond to the bill BNc. With such an embodiment, the phosphorescent ink provided at a different position for each banknote BN can be more reliably scanned by the optical sensor 102, and the accuracy of authenticity identification of the banknote BN can be further improved. ..

As shown in FIG. 8, inside the housing 100, a control board 101 provided along the bottom surface 110 and the top surface 120, an optical sensor 102 arranged on the bottom surface 110 side of the control board 101, and a control board 101. A battery 103, which is arranged on the upper surface 120 side of the above, is provided.

The control board 101 is, for example, a software program for realizing various processes, a CPU (central processing unit) for executing the software program, various hardware controlled by the CPU, and volatile or non-volatile. It is composed of a storage unit composed of storage devices such as a memory and a hard disk, and a board or the like on which these are mounted. The control board 101 also functions as a control unit that controls the optical sensor 102 and an identification processing unit that identifies the authenticity of the banknote BN based on the output from the optical sensor 102.

The control board 101 repeatedly executes the phosphorescence detection process by the optical sensor 102 for a predetermined period after the bill BN is inserted into the slit portion 30. The identification processing unit determines the authenticity of the banknote BN based on the output related to each detection process by the optical sensor 102. Further, after the elapse of the predetermined period, the identification processing unit comprehensively determines the determination result based on each detection process, and finally performs the authenticity identification of the banknote BN.

Then, the final authenticity identification result of the bill BN by the identification processing unit is displayed on the light emitting window 162 as the notification unit. The light emitting window 162 (notifying unit) notifies the authenticity identification result of the bill BN after a predetermined time has elapsed after the bill BN is inserted into the slit portion 30. With such an embodiment, the presence or absence of phosphorescent ink, which is a feature of banknote BN, is not notified in real time, and whether or not there is phosphorescent ink in any part of the banknote BN scanned within a predetermined time is determined. Since the notification is given, it is possible to make it difficult for the user to grasp the position where the phosphorescent ink is provided (the position of the security element).

The authenticity identification device 1 recognizes that the bill BN has been inserted into the slit portion 30 when the optical sensor 102 as a detection unit detects the bill BN.

The optical sensor 102 moves relative to the authenticity identification device 1 in the slit portion 30 and the light source 1021 that irradiates the bill BN inserted in the slit portion 30 with two types of excitation light having different wavelengths. It is provided with a light receiving element 1022 that receives phosphorescence emitted from the bill BN. With such an embodiment, the phosphorescence characteristic of the banknote BN can be detected. In the present embodiment, the light source 1021 irradiates ultraviolet light having a plurality of wavelengths as excitation light. The optical sensor 102 that scans one side of the bill BN not only emits phosphorescence (phosphorescence) on the main surface of the bill BN on the optical sensor 102 side, but also phosphorescence (phosphorescence) on the main surface of the bill BN opposite to the optical sensor 102. Ink) can be detected.

Since the type of excitation light that causes the phosphorescent ink used in the banknote BN to emit phosphorescent light differs from country to country, in this embodiment, two light sources 1021 that irradiate excitation light having different wavelengths from each other so as to correspond to as many countries as possible. However, the type of the light source 1021 is not limited to this, and may be one type or three or more types.

The excitation light from the light source 1021 passes through the window portion 113 provided on the bottom surface 110 and irradiates the bill BN inserted in the slit portion 30. The window portion 113 is composed of a transparent member through which the excitation light emitted from the light source 1021 and the phosphorescence emitted from the banknote BN are transmitted.

As shown in FIG. 2, the battery 103 is replaced by removing the lid portion 10B from the box-shaped portion 10A.

The first guide portion 211 has flexibility, and as shown in FIG. 9, the distance between the first guide portion 211 and the housing 100 is reduced by the pressing P of the operator (user). When detecting the characteristics of the bill BN in a state where the bill BN inserted in the slit portion 30 and the authenticity identification device 1 are relatively moved, the first guide portion 211 and the housing 100 are pressed by the pressing P. By narrowing the distance from the bottom surface 110, it is possible to suppress the influence of external light when detecting the characteristics of the banknote BN and to bring the banknote BN closer to the optical sensor 102, so that the banknote BN can be identified. The accuracy can be improved. By pressing P, the first guide portion 211 may come into contact with the second guide portion 111 via the bill BN.

FIG. 10A shows a state in which the bill BN is not inserted in the slit portion 30, and FIG. 10B shows a state in which the bill BN is inserted in the slit portion 30. The surface of the first guide portion 211 on the second guide portion 111 side is black and has irregularities. With such an embodiment, as shown in FIG. 10A, when the bill BN is not inserted into the slit portion 30, the excitation light is absorbed by the surface of the first guide portion 211, so that light is received. The element 1022 does not receive light and does not detect the bill BN. On the other hand, as shown in FIG. 10B, when the bill BN is inserted into the slit portion 30, the light receiving element 1022 receives the excitation light reflected on the surface of the bill BN and detects the bill BN. In this way, it is possible to detect whether or not the bill BN is inserted in the slit portion 30 by the difference in reflectance between the first guide portion 211 and the bill BN.

As described above, the authenticity identification device 1 of the present embodiment is an authenticity identification device for identifying the authenticity of the bill BN, and has a slit portion 30 into which a part of the bill BN can be inserted and a slit portion 30. It is provided with an optical sensor 102 that manually moves the banknote BN inserted in the banknote BN to scan the banknote BN and detects the characteristics of the banknote BN. With such an embodiment, even if there is no table on which the bill BN is placed, the characteristics of the bill BN are detected and the authenticity is determined with the optical sensor 102 arranged at a predetermined position with respect to the bill BN. Is possible, and it is possible to make it easier for the user to operate.
