In Magnetic Sensor 4, if the state producing AC magnetic field by the electric power provided from AC power 25 in the inner circumferential side of ring-type iron core 11 at excitation coil 8, game money 2 by by road 5, then the AC magnetic field variation of the inner circumferential side of ring-type iron core 11.If the AC magnetic field variation of the inner circumferential side of ring-type iron core 11, then the output valve from the output signal S1 of magnetic test coil 9 changes with the output valve of the output signal S2 carrying out Autonomous test coil 10.In the manner, if under the state producing AC magnetic field at excitation coil 8, game money 2 by by road 5, then as shown in Figure 8, becomes with the output valve of the output valve and output signal S2 that output signal S1 the testing circuit that large mode is formed Magnetic Sensor 4.

As mentioned above, the right side of protuberance 12a, 13a and the left side of protuberance 12b, 13b distance L1 is in the lateral direction equal with by road 5 width in the lateral direction, detection coil 9 to cover the upper and lower surface of protuberance 13a to 13c, the mode of left side of the right side of protuberance 13a and protuberance 13b is wound in protuberance 13a to 13c across bobbin winder bracket 21.Therefore, the output valve of the output signal S1 of detection coil 9 is because changing by the impact by the material of the game money 2 on road 5, thickness and external diameter.On the other hand, protuberance 12c, 13c are configured at protuberance 12a, 13a and between protuberance 12b, 13b, and protuberance 12c, 13c are so that no matter game money 2 passes through by which position in the lateral direction, road 5, when observing from fore-and-aft direction, overall all overlapping with game money 2 mode of protuberance 12c, 13c is formed and configures, and detection coil 10 is wound in protuberance 13c.Therefore, the output valve of the output signal S2 of detection coil 10 is mainly because of by changing by the material of game money 2 on road 5 and the impact of thickness.

Whether in game money recognition device 1, being such as identified by by the game money 2 on road 5 based on the maximal value V1 of output signal S1 and the maximal value V2 of output signal S2 is regular game money.In addition, under the state that excitation coil 8 produces AC magnetic field, make game money 2 by during by road 5, in the mode that the output valve of the output valve and output signal S2 that output signal S1 diminishes, whether when forming the testing circuit of Magnetic Sensor 4, being such as identified by by the game money 2 on road 5 based on the minimum value of output signal S1 and the minimum value of output signal S2 is regular game money.And, as mentioned above, owing to being formed with margination part 2a at game money 2, therefore as shown in Figure 8, there is peak value P1, P2 and P3 in the output signal S2 mainly changed because of the material of game money 2 and the impact of thickness in output valve, described peak value P1, P2, P3 occur when the central side of game money 2 passes through between protuberance 12c and protuberance 13c and when margination part 2a passes through between protuberance 12c and protuberance 13c.That is, there are three place peak value P1, P2, P3 at output signal S2.Also can based on the maximal value V1 of the value of this three place peak value P1 to P3 with output signal S1, whether be identified by by the game money 2 on road 5 is regular game money.

(main efficacy results of the manner)

As described above, whether in the manner, being identified by by the game money 2 on road 5 by Magnetic Sensor 4 is regular game money.Therefore, in the manner, even if do not make the component parts of Magnetic Sensor 4 contact with game money 2, also can identify whether game money 2 is regular currency.Therefore, in the manner, even if use game money recognition device 1 all the year round, the accuracy of identification of the game money 2 that also can prevent the component parts wearing and tearing etc. because of Magnetic Sensor 4 from causing declines.

In the manner, by the excitation coil 8 that reels at the OBL protuberance 12a to 12c outstanding towards the second iron core 13, OBL protuberance 13a to the 13c winding detection coil 9 given prominence to towards the first iron core 12, at protuberance 13c winding detection coil 10, forms Magnetic Sensor 4.Therefore, in the manner, the structure of the first iron core 12 and the second iron core 13 can be simplified, and the winding position that excitation coil 8 and detection coil 9,10 are wound in ring-type iron core 11 can be reduced.Therefore, in the manner, the structure of game money recognition device 1 can be simplified.

In the manner, the output valve of the output signal S1 of detection coil 9 is because changing by the impact by the material of the game money 2 on road 5, thickness and external diameter, and the output valve of the output signal S2 of detection coil 10 is mainly because of by changing by the material of game money 2 on road 5 and the impact of thickness.Therefore, in the manner, can mainly use detection coil 9 to identify the external diameter of game money 2, main material and the thickness using detection coil 10 to identify game money 2.Therefore, in the manner, the accuracy of identification of game money 2 can be improved.Such as, can identify that external diameter is identical with regular game money 2 with thickness, but non-normal game money 2 that material is different from regular game money 2 and regular game money 2, can identify that thickness is identical with regular game money 2 with material, but the external diameter non-normal game money 2 different from regular game money 2 and regular game money 2.

And, in the manner, because the right side of protuberance 12a, 13a is equal with by road 5 width in the lateral direction with the left side distance L1 in the lateral direction of protuberance 12b, 13b, therefore no matter game money 2 passes through by which position in the lateral direction, road 5, and a part for game money 2 all can not depart from from the magnetic circuit be formed between protuberance 12a to 12c and protuberance 13a to 13c.Therefore, in the manner, the output valve variation of the output signal S1 because of the game money 2 detection coil 9 caused by position in the lateral direction can be suppressed.Consequently, in the manner, the accuracy of identification of the external diameter of game money 2 can be improved.

Particularly in the manner, due to protuberance 12a, the right side of 13a and protuberance 12b, distance L5 between the right side of 13b and protuberance 12a, the left side of 13a and protuberance 12b, distance L6 between the left side of 13b is less from the external diameter of the game money 2 with minimum external diameter the game money 2 that the game money input port of Slot Machine is dropped into than imagination, therefore, no matter game money 2 passes through by which position in the lateral direction, road 5, also can not in game money 2 entirety from the state departed between protuberance 12a and protuberance 13a or between protuberance 12b and protuberance 13b, game money 2 is passed through by road 5.Therefore, in the manner, effectively can suppress the output valve variation of the output signal S1 because of the game money 2 detection coil 9 caused by position in the lateral direction, consequently, effectively can improve the accuracy of identification of the external diameter of game money 2.

Namely, as shown in Fig. 9 (A), if the right side of protuberance 12a, 13a and the distance L7 of the right side of protuberance 12b, 13b and the left side of protuberance 12a, 13a larger than the external diameter of game money 2 with the distance L8 of the left side of protuberance 12b, 13b, then likely the following two kinds situation occurs: one, as shown in the solid line of Fig. 9 (A), game money 2 passes through the situation of the mode between protuberance 12a and protuberance 13a and between protuberance 12b and protuberance 13b by road 5 with a part for game money 2; Two, as shown in the dotted line of Fig. 9 (A), game money 2 passes through between protuberance 12a and protuberance 13a with a part for game money 2, but game money 2 does not have overall by the situation of the mode between protuberance 12b and protuberance 13b by road 5.Now, the output of the output of the detection coil 9 of the previous case and the detection coil 9 of latter event significantly changes.That is, there is the output of detection coil 9 because of game money 2 worry significantly changed by position in the lateral direction.On the other hand, in the manner, no matter game money 2, by by which position in the lateral direction, road 5, can both make the stable output of detection coil 9.That is, in the manner, effectively can suppress the output valve variation of the output signal S1 because of the game money 2 detection coil 9 caused by position in the lateral direction, consequently, effectively can improve the accuracy of identification of the external diameter of game money 2.

And, in the manner, because protuberance 12c, 13c are so that no matter game money 2 passes through by which position in the lateral direction, road 5, when observing from fore-and-aft direction, overall all overlapping with game money 2 mode of protuberance 12c, 13c is formed and configures, therefore, it is possible to when the affecting of external diameter not by game money 2, identified material and the thickness of game money 2 by detection coil 10.Therefore, in the manner, the material of game money 2 and the accuracy of identification of thickness can be improved.

In the manner, be wound with excitation coil 8 and detection coil 9,10 at the ring-type iron core 11 being formed as four side ring shapes.Therefore, in the manner, the amount that the magnetic flux that can reduce excitation coil 8 generation spills from ring-type iron core 11, consequently, can form efficient magnetic circuit at ring-type iron core 11.

In the manner, the protuberance 12a being formed as same shape is configured at identical position in the lateral direction with protuberance 13a, the protuberance 12b being formed as same shape is configured at identical position in the lateral direction with protuberance 13b, and the protuberance 12c being formed as same shape is configured at identical position in the lateral direction with protuberance 13c.Therefore, in the manner, the density of the magnetic flux respectively by protuberance 13a, protuberance 13b and protuberance 13c can be improved.

And, in the manner, the left side of protuberance 12a to 12c and protuberance 13a to 13c distance L2 to be in the longitudinal direction connected iron core 14 than the right side of protuberance 12a, 13a left side with first distance L3 in the lateral direction and protuberance 12b, 13b is connected iron core 15 right side distance L4 in the lateral direction with second is short.Therefore, in the manner, the magnetic flux as shown in the arrow of the double dot dash line in Fig. 9 (B) between protuberance 12a with protuberance 13a can be suppressed to be connected iron core 14 to first and to spill and magnetic flux between protuberance 12b with protuberance 13b is connected iron core 15 to second and spills.That is, in the manner, formation can be suppressed directly to move into the magnetic circuit of the first connection iron core 14 from the rear end face of protuberance 12a and directly move into the magnetic circuit of the second connection iron core 15 from the rear end face of protuberance 12b.Therefore, in the manner, the density of the magnetic flux respectively by protuberance 13a and protuberance 13b can be improved.

Further, in the manner, protuberance 12c and protuberance 13c distance L2 in the longitudinal direction than the bee-line of protuberance 12c and protuberance 13a and the bee-line of protuberance 12c and protuberance 13b short.Therefore, in the manner, the magnetic flux as shown in the dotted arrow of Fig. 9 (B) between protuberance 12c and protuberance 13c can be suppressed to spill to protuberance 13a, 13b.That is, in the manner, can suppress to form the magnetic circuit moving into protuberance 13a, 13b from the rear end face of protuberance 12c.Therefore, in the manner, the density of the magnetic flux by protuberance 13c can be improved.

Further, in the manner, the first end face, the second end face, the 3rd end face and the 4th end face are formed with the distance longer than protuberance 12a to 12c and protuberance 13a to 13c distance L2 in the longitudinal direction.Therefore, it is possible to suppress magnetic flux to move into the first iron core 12 of front side from the rear end face of protuberance 12a, 12b, and magnetic flux can be suppressed to move into the second iron core 13 of rear side from the front end face of protuberance 13a, 13b.Further, from the rear end face of protuberance 12c to the first iron core 12 of front side distance in the longitudinal direction and longer than protuberance 12a to 12c and protuberance 13a to 13c distance L2 in the longitudinal direction to the second iron core 13 distance in the longitudinal direction of rear side from the front end face of protuberance 13c.Therefore, it is possible to suppress the rear end face of magnetic flux protuberance 12c upwards from front and back to move into the first iron core 12 of front side, and magnetic flux can be suppressed to move into the second iron core 13 of rear side from the front end face of protuberance 13c.Therefore, in the manner, can improve from protuberance 12a to protuberance 13a, from protuberance 12b to protuberance 13b and from protuberance 12c to the magnetic flux density of protuberance 13c.

In the manner, be wound with excitation coil 8 and detection coil 9,10 at the ring-type iron core 11 being formed as roughly four side ring shapes.Therefore, even if be configured at by game money recognition device 1 towards in the external magnetic field of any direction in the XY plane be made up of X-direction and Y-direction, the magnetic circuit caused because of external magnetic field also can not be formed at by road 5.Such as, even if direction game money recognition device 1 being configured at the magnetic line of force is towards in the external magnetic field (arrow in Figure 10) of backward directions, as shown in Figure 10, the magnetic circuit caused because of external magnetic field also can not be formed at by road 5.That is, in the manner, ring-type iron core 11 can be made to play magnetic shielding, consequently, the accuracy of identification of the game money 2 that the external magnetic field because of game money recognition device 1 can be suppressed to cause declines.In addition, even if be configured at by game money recognition device 1 towards in the external magnetic field of above-below direction (Z-direction), because above-below direction is orthogonal with the magnetic strength direction of detection coil 9,10, therefore, game money recognition device 1 is not subject to the impact of external magnetic field.
