Description

  The present invention relates to a disc body sorting device and disc body authenticity determination method used in vending machines, currency exchange machines, pachinko ball lending machines, medal lending machines, etc., and in particular, attached to vending machines, and disc bodies The present invention relates to a disc body sorting device for discriminating and discriminating whether a coin is true or false and a disc body true / false judgment method.

  2. Description of the Related Art Conventionally, vending machines or the like are provided with a disc body sorting device for determining the authenticity of inserted coins, storing coins as needed, or returning them from a return port. As a method for determining the authenticity of the disc body, a method is proposed in which a grim pattern on the outer peripheral side of the coin or a protrusion pattern on the outer peripheral side is detected and the authenticity of the inserted coin is determined based on the detection result. (For example, see Patent Documents 1 and 2).

  In recent years, many cases of forgery of coins have occurred, and the shape and pattern of coins have become complicated in order to make it difficult to forge. In the method disclosed in Patent Document 2, not only the outer peripheral side surface of a coin but also a protrusion near the outer periphery of the front or back surface of the coin is detected to determine the authenticity of the coin. By using this method, it is possible to improve the authenticity of the coin as compared with the method of detecting only the outer side surface burrs.

By the way, in order to easily manufacture coins (may be medals), a process of forming a pole pattern on the front and back surfaces of a coin and a process of forming a pattern (for example, a jagged pattern) on the outer peripheral side surface of the coin are combined. A coin manufacturing method performed in a process has been proposed (see, for example, Patent Document 3). The coin manufactured by such a manufacturing method has a positional correlation between the pattern on the front surface or the back surface and the pattern on the outer peripheral side surface. In order to determine the authenticity of such a coin, it is not sufficient to use only the method disclosed in Patent Document 2 that determines the authenticity of a coin by imaging the edge of the coin.

(A)) and a plan view (FIG. 1B) are shown. In the present embodiment, as shown in FIG. 1, the disc body A has a plurality of feature points a in which six serrated patterns are missing on the outer peripheral side surface. Here, “having positional correlation” means that, in the regular disc A, the concave / convex pattern on the outer peripheral side surface is a predetermined pattern, and only a predetermined pole is provided on the front and back surfaces thereof. Rather, it means that the positional relationship between the concave / convex pattern on the outer peripheral side surface and the marked pattern on the front and back surfaces has a predetermined correlation. For example, when a feature point a as shown in FIG. 1 is arranged at a predetermined position and viewed from a predetermined direction, the top and back polar patterns become a fixed pattern. That is, in the disc body A having such a positional correlation, the top and bottom pole patterns with respect to a certain characteristic point a are determined to be only one when viewed from a predetermined direction. The feature point a in the predetermined concavo-convex pattern is, for example, a feature point set intermittently (discretely or discontinuously) along the outer peripheral side surface of the disc body A, or on the outer peripheral side surface of the disc body A. These are feature points set in association with specific phases.

  In the present invention, the “predetermined concavo-convex pattern” is not a regular interval as provided in a conventional coin, but is a pattern depending on, for example, the presence / absence of an interval or a difference in interval. However, the predetermined concavo-convex pattern is not limited thereto, and may be, for example, a pattern provided with extreme marks such as characters and marks as long as it has a positional correlation as described above. Further, the number of feature points a on the outer peripheral side surface of the disk A is not limited to six, and may be a plurality other than six as long as it has a positional correlation as described above. Here, as the disc body A to be determined according to the present invention, a coin (regardless of domestic or overseas), a medal, a coin, or the like is assumed.

  First, the configuration of the disc body sorting device of the present invention will be described. FIG. 2 is a block diagram schematically showing the configuration of the disc body sorting apparatus 10 in one embodiment of the present invention. As shown in FIG. 2, the disk body sorting apparatus 10 includes a pole mark detection means 2 that detects the pole marks on the front and back surfaces of the disk body A as pole data, and a concavo-convex pattern on the outer peripheral side surface of the disk body A (that is, A concavo-convex pattern detecting means 3 for detecting dents and the like as concavo-convex pattern data, and a control unit 1 for controlling the entire disc body sorting apparatus 10 including the pole mark detecting means 2 and the concavo-convex pattern detecting means 3. The pole detection unit 2 and the uneven pattern detection unit 3 are connected to the control unit 1 via A / D converters 4A and 4B, respectively.

  Here, the control unit 1 includes a CPU that performs arithmetic processing on detection data such as a detection result (pole data) of the pole detection means 2 and a detection result (concave pattern) of the uneven pattern detection means 3 using a predetermined algorithm. Although the pole detection means 2 is not limited, it is a magnetic sensor or an imaging means for detecting the poles on the front surface or the back surface of the disk A. Moreover, although the uneven | corrugated pattern detection means 3 is not limited, it is an optical sensor or a magnetic sensor for detecting the uneven | corrugated pattern of the outer peripheral side surface of the disc body A. As shown in FIG.

  In addition, the disk body sorting device 10 has a memory 5 that stores in advance the mark data of the front surface or the back surface of the disk body A corresponding to the feature point a of the predetermined uneven pattern (hereinafter referred to as “determination mark data”). Prepare. In the memory 5, for example, front and back pole patterns (pole data) having a specific positional correlation with each feature point a of the disk A are stored as image data and magnetic data. In the present embodiment, at least 12 types of determination mark data are stored in the memory 5 as front and back pattern data for six feature points. When the disk body A is inserted into the disk body sorting apparatus 10, the control unit 1 uses the detection data detected by the pole detection means 2 and the uneven pattern detection means 3 at a predetermined timing (for each detection means 2, 3). The detectable area is received at the moment when the disk A passes. And the control part 1 expand | deploys the received detection data (uneven | corrugated pattern data and mark data) in the memory 5, in order to determine the authenticity of the disk body A mentioned later. The control unit 1 detects the polar mark data (hereinafter referred to as the following) detected at a predetermined timing based on the polar mark data and the concave / convex pattern data detected in the polar mark detection means 2 and the concave / convex pattern detection means 3 and developed in the memory 5. “Detected mark data”) is temporarily stored in the memory 5.

The authenticity determination means 6 collates the detection mark data stored in the memory 5 by the control unit 1 as described above with a plurality of determination mark data stored in the memory 5 in advance, and the detected mark data is any of the detection mark data. It is determined whether or not it matches the determination mark data. Thereby, the authenticity determination means 6 determines whether or not the disc body A has a positional correlation between the concavo-convex pattern and the pole mark. As a result, the authenticity determination means 6 is inserted based on the determination result. The authenticity of the disc body A is determined. That is, if the detected mark data does not match any of the determination mark data, the authenticity determination means 6 determines that the inserted disc A is false (fake). On the other hand, if the detected mark data matches any of the determination mark data, the authenticity determination means 6 determines that the inserted disc A is true (genuine).

When the disc body sorting means 7 and the control unit 1 determine that the disc body A inserted by the authenticity judging means 6 is a fake, the disc body A is, for example, a disc body return port (not shown). )) To return. If the disc body A input by the authenticity judging means 6 is determined to be true (genuine), the disc body distributing means 7 converts the disc body A into a disc body storage unit (not shown). The control unit 1 counts according to the value of the disc body A.

  Hereinafter, a specific configuration of the disc body sorting apparatus 10 of the present invention and its authenticity determination processing will be described based on specific examples 1 to 3.

(Specific example 1)
First, the configuration of the specific example 1 will be described. FIG. 3 is a partial cross-sectional view and a detected waveform diagram of the disc body sorting apparatus 10A according to an embodiment of the present invention. As shown in FIG. 3A, the disc body sorting device 10 </ b> A of this example includes a magnetic sensor 12 as the pole detection means 2 and a plurality of optical sensors 13 as the concavo-convex pattern detection means 3. As shown in FIG. 3B, each optical sensor 13 includes a pair of light emitting units 13a (for example, light emitting diodes) and a light receiving unit 13b. When the disc body A is present at a predetermined position in the disc body passage 9, a plurality of optical sensors 13 are arranged outward along the outer periphery of the disc body A, and the surface of the disc body A or The magnetic sensor 12 is disposed at a position facing the back surface. The number of the optical sensors 13 is not particularly limited as long as it is a number that can reliably detect the characteristic point a of the target disk A.

  The disk body A introduced from the insertion port 8 of the disk body sorting apparatus 10 </ b> A rolls down through the disk body passage 9. When the disk body A reaches a predetermined position in the disk body passage 9, the uneven pattern on the outer peripheral side surface of the disk body A is detected by the plurality of optical sensors 13, and the surface of the disk body A is detected by the magnetic sensor 12. Alternatively, the pole on the back surface is detected. The detected concavo-convex pattern data and pole data are sent to the control unit 1 via the A / D converters 4A and 4B.

  Next, the operation of the disc body sorting apparatus 10A of the first specific example will be described. FIG. 4 is a flowchart of the disk body authenticity determination process executed by the disk body sorting apparatus 10A shown in FIG. Hereinafter, the disc body authenticity determination process executed by the disc body sorting apparatus 10A of the first specific example will be described with reference to FIG. 3 and FIG.

  First, when the disc body A is inserted (step S101), the uneven pattern on the outer peripheral side surface of the disc body A is detected by the plurality of optical sensors 13 at a predetermined timing (step S102). In step S <b> 103, the control unit 1 determines whether or not the feature point “a” on the outer peripheral side surface of the disk A is detected by the plurality of optical sensors 13. Here, as shown in FIGS. 3A and 3C, for example, the feature point a of the disk A is detected in the optical sensor 13 (c).

  When it is determined by the control unit 1 that the feature point a has been detected, the magnetic sensor 12 detects a pole on the front surface or the back surface of the disk A corresponding to the feature point a (step S104). The pole data detected by the magnetic sensor 12 is temporarily stored in the memory 5 as detected pole data. Then, the true / false determination means 6 collates the detected pole data (detected pole data) with a plurality of pieces of pole data (determination pole data) stored in advance as judgment reference data in the memory 5 (step S105). ). In addition, when the feature point a is detected also in the other optical sensors 13, the process of step S104 and S105 should just be performed corresponding to the detected several feature point a.

  In step S106, the authenticity determination means 6 determines whether or not the detected mark data matches any of the plurality of determination mark data. If it is determined that the detected mark data matches any of the determination mark data, the true / false determining means 6 determines that the disk A is true (genuine) (step S107). On the other hand, if it is determined that the detected mark data does not match any of the plurality of determination mark data, the authenticity determination means 6 determines that the disk A is false (fake) (step S108). Thereafter, the disk body distributing means 7 distributes the disk body A subjected to the determination as described above based on the determination result of the authenticity determining means 6 (step S109).

(Specific example 2)
Hereinafter, the configuration and operation of the disc body sorting apparatus 10B according to the second specific example will be described with a focus on differences from the first specific example. FIG. 5 is a partial cross-sectional view and a detected waveform diagram of a disk body sorting device 10B according to another embodiment of the present invention. In this disc body sorting apparatus 10 </ b> B, a magnetic sensor 23 is used as the concavo-convex pattern detecting means 3 instead of the plurality of optical sensors 13. In this case, the magnetic sensor 23 as the concave / convex pattern detecting means 3 is, for example, inserted into a predetermined region of the disc body passage 9 so as to face the outer peripheral side surface of the disc body A (for example, the lower surface of the disc body passage 9). Are arranged in parallel to the surface on which the disk A contacts and rolls. The magnetic sensor 23 is not limited to such a position, and may be arranged at any position as long as the feature point a of the disk A can be detected, and the number of arrangement is not one. There may be a plurality. The detectable region of the magnetic sensor 23 (the length in the longitudinal direction of the magnetic sensor 23 parallel to the rolling-down direction) may be set so that at least one feature point a can be reliably detected. The magnetic sensor 22 as the pole detection means 2 has the same configuration as the magnetic sensor 12 of the first specific example.

  Next, the operation of the disc body sorting apparatus 10B of the specific example 2 will be described. FIG. 6 is a flowchart of the disk body authenticity determination process executed by the disk body sorting apparatus 10B shown in FIG. As can be seen from this flowchart, the flowchart shown in FIG. 4 differs from the flowchart shown in FIG. In this example, when the inserted disc body A rolls down the disc body passage 9, the magnetic sensor 23 as the concavo-convex pattern detecting means 3 detects the feature point a on the outer peripheral side surface of the disc body A (step S202). , S203 (see FIG. 5B), the same processing as steps S104 to S109 of the first specific example is executed.

(Specific example 3)
Hereinafter, the configuration and operation of the disc body sorting apparatus 10C of the specific example 3 will be described focusing on the differences from the specific example 1. FIG. 7 is a partial cross-sectional view of a disk body sorting apparatus 10C according to still another embodiment of the present invention. The disc body sorting device 10 </ b> C includes a cradle 31 that temporarily holds the disc body A that has been inserted. In the disc body sorting device 10 </ b> C, a single optical sensor 33 is used instead of the plurality of optical sensors 13 as the concavo-convex pattern detecting means 3, and an imaging means 32 is used as the pole detection means 2 instead of the magnetic sensor 12.

  In this case, the optical sensor 33 follows the arc drawn by the outer peripheral surface of the disk body A when the cradle 31 holding the disk body A rotates to send the disk body A to the disk body passage 9. Placed outside. The imaging means 32 is arranged so as to be able to image the trajectory region of the front surface or the back surface of the disk A when the cradle 31 is rotated. As shown in FIG. 7B, the imaging means 32 illuminates the imaging element 32a composed of a CCD or CMOS and the front or back surface of the disk A when imaging the disk A with the imaging element 32a. A plurality of light sources 32b. In this example, the number of optical sensors 33 is not limited to one, and a plurality of optical sensors 33 may be provided. Further, the light source 32b of the imaging means 32 may be one or three or more as long as the imaging element 32a can image the front surface or the back surface of the disc body A.

  Next, the operation of the disc body sorting apparatus 10C of the specific example 3 will be described. FIG. 8 is a flowchart of the disk body authenticity determination process executed by the disk body sorting apparatus 10C shown in FIG. As can be seen from this flowchart, the flowchart in FIG. 4 is different from the flowchart in FIG. 4 in that, in step S304, the front or back pole of the disk A is detected by the imaging means 32. In this example, when the disc body A is inserted, the disc body A is temporarily held by the cradle 31. As is well known, when the target disk body A (disk body A having a predetermined diameter) is temporarily held, the cradle 31 rotates in a predetermined direction due to the eccentricity of the center of gravity. As a result, the cradle 31 can feed the disc body A held to the disc body passage 9.

  The optical sensor 33 detects the concavo-convex pattern on the outer peripheral side surface of the disk A when the cradle 31 is rotated (step S302). When the feature point a of the concavo-convex pattern is detected by the optical sensor 33 (step S303), the control unit 1 drives the light source 32b of the imaging unit 32 to illuminate the front or back surface of the disk A, and the imaging element 32a The pole of the disc body A corresponding to the feature point a is imaged (step S304). The mark data captured by the image sensor 32 a is stored in the memory 5 via the control unit 1. Then, the authenticity determination means 6 collates the imaged mark data with a plurality of mark data (determination mark data) stored in the memory 5 (step S305). Thereafter, processing similar to steps S106 to S109 of the first specific example is executed.

  As described above, the disc body sorting apparatus 10 according to the present invention has a predetermined uneven pattern on the outer peripheral side surface, and the poles provided on the front and back surfaces thereof have a positional correlation with the predetermined uneven pattern. The authenticity of the disc body A is determined. When the concavo-convex pattern detecting means 3 detects the concavo-convex pattern on the outer peripheral side surface of the disc body A as the concavo-convex pattern data and detects the feature point a for detecting the concavo-convex pattern, the polar mark detecting means 2 The pole on the front or back side of A is detected as pole data, and the control unit 1 stores the detected pole data in the memory 5. The authenticity determination means 6 collates the detection mark data stored in the memory 5 with a plurality of determination mark data stored in advance in the memory, and if the detection mark data matches any of the determination mark data. The disc body A is determined to be true (genuine). Since the disc body sorting apparatus 10 of the present invention is configured as described above, if the discriminating means 6 determines that the disc body A is a fake disc body A, the disc body A is regarded as a fake in a later stage. Can be sorted. Therefore, according to the disk body sorting apparatus 10 of the present invention, the disk body A (for example, a coin or medal) having a positional correlation between the pattern on the outer peripheral side surface (uneven pattern) and the marked pattern on the front and back surfaces. Can be more accurately determined, and a counterfeit disc body can be distributed in the subsequent stage based on the determination result.

  As mentioned above, although embodiment of the disc body sorting device of the present invention was described in detail based on an accompanying drawing, the present invention is not limited to these composition, and it is in a claim, a specification, and a drawing. Various modifications are possible within the scope of the described technical idea. In addition, even if it has a shape, structure, or function that is not directly described in the specification and drawings, it is within the scope of the technical idea of the present invention as long as it has the effects and advantages of the present invention. That is, each part which comprises a disc body classification | selection apparatus can be substituted with the thing of the arbitrary structures which can exhibit the same function. Moreover, arbitrary components may be added. For example, the optical sensors 13 and 33 and the magnetic sensor 23 are given as examples of the concavo-convex pattern detecting means 3, and the magnetic sensors 12 and 22 and the imaging means 32 are given as examples of the pole detection means 2. Other sensors may be used as long as they exhibit the action / effect. Moreover, the combination of these sensors is not limited to the above-described specific examples 1 to 3, and other combinations are possible. Further, the disk body sorting apparatus of the present invention may be provided with means for detecting the insertion of the disk body and determining the insertion of the disk body. In this case, when it is determined that the disc body is inserted, the above-described uneven pattern may be detected.

  Further, the disk body sorting apparatus of the present invention may have a structure for temporarily holding the disk body A other than the cradle 31 as in the specific example 3, and the unevenness of the held disk body A Patterns and poles may be detected.

  As can be seen from the description of specific examples 1 to 3, the disc body sorting device of the present invention generally has a disc body (coin or coin) to be sorted, such as a 500 yen coin. One is decided. However, by providing a plurality of the pole detection means 2 and the concavo-convex pattern detection means 3 so as to correspond to the diameters of the other disk bodies, the disk body sorting apparatus of the present invention can realize the trueness of two or more types of disk bodies. False can be accurately determined, and these disc bodies can be selected in a later stage.
