The present invention relates to a medal sorting device for gaming machines that has taken measures to prevent pseudo medal insertion.

  Conventionally, in gaming machines such as slot machines and pachinko machines, it is determined whether or not a disc-shaped game medium (hereinafter simply referred to as “medal”) inserted by a player to play the game, and only prescribed medals are selected. A medal sorting device is provided (see, for example, Patent Document 1).

JP 2001-155223 A

  This kind of medal sorting device has a new gaming machine such as a medal sorting means for determining whether or not a inserted medal satisfies a predetermined condition such as having a certain size and shape, and a reel is rotating. Mainly composed of forcible exclusion means for forcibly removing medals inserted in a state prohibiting the insertion of various medals, and medal sensors for detecting medals accepted through the medal selection means and forcible exclusion means Yes.

  A conventional medal sensor has a reflection type optical sensor composed of a light emitting element and a light receiving element, and two optical sensors are arranged side by side along a medal guide path guided from the forcible exclusion means. . A method is generally employed in which each optical sensor detects reflected light reflected by a medal passing through the front surface thereof, and detects the movement of the medal based on the timing difference.

  Incidentally, in recent years, as shown in FIG. 1, by improperly inserting an unauthorized instrument F into the medal sorting device 900 and causing the light emitting element Fl provided at the tip to emit light, the same light receiving / emitting timing as the passage of the medal is simulated. An illegal act that reproduces and erroneously operates the medal sensors 901 and 902 is a problem. When such a fraudulent instrument F is used, it is possible to simulate the insertion of medals, and there is a risk that the hall providing the game may suffer a great damage. In response to such a problem, recently, a so-called pulse modulation in which a light emitting element emits pulsed light modulated by a predetermined signal and a light receiving element receives reflected light synchronized with the signal. The detection method by has been adopted.

  However, following the technical progress of anti-fraud measures in such a medal sorting device, the above-described fraudulent instruments have also become more sophisticated. For example, a light-emitting element is not used for the medal sensor that is detected by the pulse modulation method described above. Fraudulent instruments that irradiate light-receiving elements with false sync light based on the emitted pulsed light are also in the dark. As described above, it has not been possible to reliably prevent an illegal act using such a fraudulent instrument by a conventional medal sorting device.

When they match, the winning is confirmed, and a medal with the number of payouts corresponding to the type of winning combination is added to the credit. When the credit exceeds the upper limit due to the winning payout, the excess medals are paid out from the hopper device to the tray unit 6a.

  Next, the medal sorting device 100 according to the present invention mounted on the slot machine 1 or the like will be described. Here, FIG. 4 is an external view mainly showing the internal structure of the medal sorting device 100 with the cover member on the front side partially broken. As shown in the figure, the medal sorting device 100 has a gate plate 120 made of a metal plate so as to substantially cover the upper half of a case 110 integrally formed of hard plastic as a rectangular box body whose front surface is open. Is attached so that it can be opened and closed. A medal guide passage is formed in the gap formed by the gate plate 120 and the back surface of the case 110, leading from the medal inlet 130 to the medal outlet 150 at the lower right via the transfer rail portion 140 at the lower end of the gate plate 120.

  The transfer rail portion 140 has a rail surface formed by obliquely bending the lower end portion of the gate plate 120 toward the case 110 side, and the peripheral surface of the disk-shaped medal abuts on the rail surface, so that the medal on the downstream side It is formed so as to roll and drop linearly to the outlet 150. Further, the transfer rail 140 is separated from the notch 141 corresponding to the minimum standard outer diameter of the prescribed medal from the lower edge to the upper edge, and from the end of the notch 141, An inclined wall portion 142 that is inclined toward the front side in the drawing is formed.

  For example, when a medal having an outer diameter equal to or less than the standard reaches the transfer rail portion 140, the medal is pushed by the pressing lever 160 that is constantly urged outward to be detached from the notch 141, and the inclined wall 142 Defeated to the side. Thereby, a medal having an outer diameter smaller than the determined standard dimension deviates from the rail surface of the transfer rail portion 140 and falls downward.

  Further, in the vicinity of the medal entrance 130, a maximum diameter restricting means that prevents a medal having an outer diameter equal to or larger than the standard and a plate thickness restricting means that prevents a medal having a thickness equal to or larger than the standard from passing are formed. By these means including medals, a medal selecting means 170 for selecting a prescribed medal is formed.

  At the middle position of the transfer rail section 140 described above, forcible exclusion means 180 for forcibly removing medals distributed as prescribed medals by the medal sorting means 170 is provided. The forcible exclusion means 180 is rotatable through a metal restricting claw member 181 that is pivotally supported so as to protrude or retract into the transfer rail section 140 and the gate plate 120 via a biasing means. A guide lever 182 that is pivotally supported and is always urged to an angle that covers the medal passing through the transfer rail portion 140 so as not to fall to the inclined wall portion 142 side.

  A solenoid (not shown) is provided behind the regulating claw member 181, and when the required drive current is supplied to the solenoid by the main control board 20, the regulating claw member 181 is attracted and transferred by a magnetic force. Retreat from the rail part 140. The medal M inserted in this state passes through the forced exclusion means 180 and is sent to the medal sensor 190.

  Further, when the slot machine 1 is in a state of prohibiting acceptance of a new medal, such as when the reels 81a, 81b, 81c are rotating, the drive current is not supplied to the solenoid, and the restriction claw member 181 It is in a pivot position that protrudes into the transfer rail section 140. When the medal M is transferred to the forcible exclusion means 180 in this state, the medal M collides with the restricting claw member 181 and is overturned to the inclined wall 142 side by overcoming the urging force of the guide lever 182. Thereby, the medal M falls from the rail surface of the transfer rail part 140 and is removed to the lower guide member (34) side.

  A medal sensor 190 that detects a medal that has passed through the forcible exclusion means 180 is provided at a downstream position of the transfer rail portion 140. The medal sensor 190 includes two reflective photosensors 191 and 192 arranged side by side in the medal movement direction (guide direction). Note that the reflection type photosensors 191 and 192 each have a light emitting / receiving portion in which a light emitting element and a light receiving element are arranged in parallel on the front surface. The photosensors 191 and 192 have a so-called pulse modulation method in which the light emitting element periodically emits pulsed light modulated with a predetermined signal period, and the detection operation is performed only when the light receiving element receives reflected light synchronized with the signal. It has been adopted.

  When the medal M is guided by the transfer rail unit 140 and passes through the front surfaces of the photosensors 191 and 192, the medal sorting device 100 has the timing of these detection signals in a predetermined order and within an allowable time difference. When it is determined that there is a token, this is regarded as detection of a regular medal, and a medal insertion (command) signal is transmitted to the main control board 20. When receiving a medal insertion signal from the medal sorting device 100, the main control board 20 increments the credit by one.

  The medal sensor 190 has a function form that prevents the unauthorized device from entering and prevents the photosensors 191 and 192 from malfunctioning due to the unauthorized device, and a specific embodiment thereof will be described below. In the description of the embodiment of the present invention, “medal movement direction” and “guide direction by medal guide passage” are used in the same direction, that is, in the same meaning.

  FIG. 5A is a plan view of the medal sensor 190 mounted on the medal sorting device 100 and provided with wall members 210 and 220 as one means for preventing fraud, and FIG. It is a perspective view showing the appearance.

  As described above, the medal sensor 190 includes the reflective photosensors 191 and 192 arranged side by side along the medal guide path. Each of the photosensors 191 and 192 includes a light emitting element that emits visible light or near infrared light, and a light receiving element that receives the light emitted from the light emitting element and reflected by the detection target (medal). Are arranged on the same surface. However, in order to accurately detect an object at a certain distance from the front surface of the sensor, each light reception / emission is performed at an angle determined from the distance between the light receiving element and the light emitting element and the detection distance between the front surface of the sensor and the object. The elements are installed in directions facing each other.

  Wall members 210 and 220 having a rectangular flat plate shape are provided on the side surfaces of the upstream and downstream photosensors 191 and 192 in the medal guiding direction, and the tip portions (protruding portions 211 and 221) are on the medal guiding path side. It sticks with an adhesive etc. so that it may protrude and to oppose the said guide direction.

  FIG. 6 is a plan view for explaining the operation of preventing the unauthorized device F from entering by the wall members 210 and 220 attached to the medal sensor 190 and preventing the photosensors 191 and 192 from malfunctioning. As shown in FIG. 6A, when the illegal instrument F enters the medal sorting device (100) and reaches the vicinity of the medal sensor 190, a wall that faces the guiding direction of the medal guiding passage and is located on the upstream side. The member 210 (protruding portion 211) is obstructed, and it is difficult to allow the unauthorized device F to enter further. Accordingly, it is impossible to perform an illegal act such as installing the improper instrument F on the front surface of the medal sensor 190 to cause a malfunction.

  Further, as shown in FIG. 5B, even if the unauthorized device F is allowed to enter the position of the downstream photosensor 192 beyond the wall member 210, the protruding portion 211 that protrudes toward the medal guide passage side. Since 221 is formed, the improper instrument F cannot be installed in the vicinity of the photosensors 191 and 192. On the other hand, the photosensors 191 and 192 are formed so that the detection operation is performed only when the reflected light synchronized with the pulsed light emitted from the light emitting element is received, and the unauthorized device F is separated from the front surface of the photosensors 191 and 192. Under such conditions, it is extremely difficult to reproduce such false sync light. That is, when using the fraudulent instrument F, it is necessary to make it close to the front surface of the photosensor. However, since the protrusions 211 and 221 are formed, it cannot be installed closer than the protrusion amount D. . Therefore, it is impossible to cause the photosensors 191 and 192 to malfunction by using the fraudulent instrument F, and it is possible to reliably prevent fraudulent acts that artificially create medal insertion.

  In the present embodiment, the example in which the above-described wall members 210 and 220 are additionally attached to the existing medal sensor 190 and the protruding portions 211 and 221 are provided has been described. However, the above-described protruding portions 211 and 221 are provided on the front surface of the medal sensor. May be integrally formed in advance.

  As shown in FIG. 7, the wall member 210 may be attached only to the side surface of the upstream photosensor 191 in the medal guiding direction to form the protruding portion 211.
