Description

  The present invention relates to a gaming machine such as a slot machine in which a medal is inserted to play a game, and relates to a fraud prevention tool for preventing the fraud and a gaming machine equipped with the fraud prevention tool.

Conventionally, a slot machine, which is a kind of this type of gaming machine, is provided with a sideways medal slot with an upper surface open on one side of the front surface, and a medal slot is in contact with the medal slot on one side, that is, at the rear end. A guide plate is provided to stand upward so as to be easily inserted. An inserted medal detection device for detecting inserted medals is disposed below the medal slot. As shown in FIG. 6A, the inserted medal detection device 14 is provided on the downstream side of the medal guiding rod 17 and the medal guiding rod 17 through which the medal M inserted from the medal inserting port 4 flows down. A medal counter 18 that counts medals M, and a medal distributor 21 that is provided on the upstream side of the medal guide rod 17 and switches the flow direction of the medals M flowing down to discharge the medals M to the outside. A passing direction detection device 23 is disposed upstream of the medal distributor 21 in order to prevent fraudulent activity caused by the entry of a fraudulent shading plate B called a relatively hard synthetic resin cell plate ( For example, see Patent Document 1.)
JP 7-59901 A (page 2-4, FIG. 1)

  The medal counter 18 has two optical sensors 19a and 19b, and detects the number of passing medals M and the flow direction thereof. In this way, the flow-down direction is detected, for example, as shown in FIG. 6 (b), by allowing the fraudulent shading plate B to enter the medal guiding rod 17 from the medal slot 4 and using the fraudulent shading plate B. This is because the medal counter 18 may be illegally operated by shielding the optical sensors 19a and 19b, and therefore it is determined that the illegal light shielding plate B is illegal. Since the fraudulent shading plate B is relatively hard, it is necessary to enter the medal slot 4 from directly above, but since there is no obstacle above the medal slot 4, it can be easily penetrated. It has become so.

  However, in order to prevent the medal M from being swallowed into the machine, the detection of the medal counter 18 is stopped after the start switch of the slot machine is operated. For this reason, if the fraudulent shading plate B is inserted from the medal slot 4 and the medal counter 18 is detected and then the start switch is operated, and then the fraudulent shading plate B is pulled out, fraud cannot be detected. Therefore, when trying to pull out the fraudulent light shielding plate B as described above, the passing direction is detected by the optical sensors 24a and 24b of the passage direction detecting device 23, and the fraudulent light shielding plate B is pulled out even after the start switch is operated. Detect and prevent fraud.

  However, even if the passing direction detection device 23 is provided as described above, between the light sensors 19a, 19b, 24a, 24b and the bottom surface of the medal guide rod 17 in the medal counter 18 and the passing direction detection device 23. Is operated at a certain interval, passing through both optical sensors 24a and 24b of the passing direction detecting device 23 by narrowing the width of the fraudulent light shielding plate B, etc., and shielding the optical sensors 19a and 19b of the medal counter 18 The current situation is that there is no refusal to do something wrong.

  Accordingly, the present invention has been made in view of the above-described problems, and an anti-fraud device that prevents illegal acts caused by blocking the intrusion of the light shielding plate by surrounding the medal slot with a baffle member and An object of the present invention is to provide a gaming machine provided with the anti-tampering tool.

  In order to achieve such an object, the anti-fraud device according to the present invention is arranged along the outer peripheral edge of a medal insertion guide plate erected on one side of the medal insertion slot and surrounds the outer peripheral edge, and the medal insertion slot. It has an arch-shaped baffle member that protrudes to the side by a predetermined width and surrounds the medal slot, and the baffle member prevents the unauthorized shading plate from entering the medal slot.

  The gaming machine is arranged along the outer peripheral edge of the medal insertion guide plate standing on one side of the medal insertion slot and surrounds the outer peripheral edge and protrudes by a predetermined width toward the medal insertion slot side. It has an anti-fraud tool having an arch-shaped baffle member that surrounds the mouth and preventing the fraudulent shading plate from entering the medal slot by the baffle member.

  The fraud prevention device according to the present invention is disposed along the outer peripheral edge of a medal insertion guide plate standing on one side of the medal insertion slot and surrounds the outer peripheral edge and protrudes by a predetermined width toward the medal insertion slot side. Since it has an arch-shaped baffle that surrounds the medal slot, if this anti-tampering device is provided in the gaming machine, it will not be possible to enter the fraud shading plate from the medal slot by being disturbed by the baffle. This has the beneficial effect of preventing fraud.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a tamper-proof device and a gaming machine equipped with the tamper-proof device according to the present invention will be described below with reference to the drawings. In the present invention, a slot machine will be described as an example of a gaming machine. FIG. 1 is a front view of a slot machine to which a fraud prevention device according to the present invention is applied. In the figure, S is a slot machine. A window opening 1 is opened at the center of the front surface of the slot machine S. Three reels 2, 2 and 2 on which a plurality of information such as letters and numbers are arranged along the outer peripheral surface face the window opening 1. Yes. These three reels 2, 2, and 2 are adapted to rotate in a vertical plane.

  A horizontal step 3 is formed below the window opening 1, and a medal slot 4 is disposed on one side of the step 3. The medal slot 4 will be described in more detail. A base 5 is provided on the upper surface of the stepped portion 3. The upper surface 5a of the base 5 is formed into an arcuate surface extending in the front-rear direction so that the outer peripheral surface of the medal M is in sliding contact, and the medal slot 4 is opened at the rear end. Therefore, the front edge of the medal slot 4 has an arc shape. Then, a medal insertion guide plate 6 is erected so as to stand upward so as to contact the rear edge of the medal insertion slot 4. When the player releases the medal M with his fingertip while pressing the medal M against the front surface 6 a of the id plate 6, the medal M naturally falls into the medal slot 4. The upper edge of the id plate 6 is formed in an arc shape.

  A start lever 7 for rotating the reels 2 is attached to the front surface of the slot machine S and below the stepped portion 3, and each reel 2 is desired corresponding to each reel 2 rotating to one side thereof. Three stop button switches 8 for stopping at the position are arranged in parallel. Further, a medal storage tray 10 for storing the medals M discharged from the medal discharge port 9 is attached to the lower end portion of the front surface of the slot machine S. Reference numeral 11 is a speaker provided on one side thereof, and 12 is an alarm buzzer disposed on the upper part thereof. An alarm lamp 13 is mounted on the upper surface of the slot machine S.

  An inserted medal detection device 14 is disposed inside the slot machine S and below the medal slot 4. In the slot machine S of the present embodiment, the inserted medal detection device 14 shown in the conventional example is used, so the inserted medal detection device 14 shown in the conventional example will be described in a little more detail.

  As shown in FIG. 6 (a), the inserted medal detection device 14 has a receiving port 15 for receiving a medal M inserted in communication with the medal insertion port 4 at the upper end, and the medal discharging device (see FIG. A medal guide rod 17 having a discharge port 16 for discharging to a not shown) is provided. The medal guide bar 17 is formed to have a width that is slightly wider than the thickness of the medal M, and is inclined downward.

  A medal counter 18 is provided on the upstream side of the discharge port 16. The medal counter 18 has two optical sensors 19a and 19b arranged in parallel along the medal flow direction, and counts the number of medals discharged from the discharge port 16 through the medal guide rod 17. I have to. The reason why the two optical sensors 19a and 19b are arranged side by side in the medal flow direction is to prevent illegal actions by detecting the direction in which the medal M passes in addition to counting the number of medals flowing down.

  On the upstream side of the medal counter 18, a medal distribution slot 20 is opened by cutting out the bottom of the medal guide rod 17 with a length slightly larger than the diameter of the medal M. The medal distribution port 20 is attached with a medal distribution unit 21 that closes the medal distribution port 20 in an openable and closable manner. The medal distributor 21 is attached so as to be swingable in the width direction of the medal guide rod 17, and a drive device 22 for swinging the medal distributor 21 is attached to one side surface.

  The drive device 22 is composed of, for example, a solenoid (not shown), and the tip of the plunger is attached to one side of the medal distributor 21. Then, the plunger is always protruded by the biasing force of a biasing member (not shown) such as a spring, and the medal distribution unit 21 closes the medal distribution port 20. When the solenoid is excited, the plunger is attracted against the biasing of the biasing member, and the medal distributor 21 connected to the plunger swings to open the medal distributing port 20. On the other hand, when the solenoid is demagnetized, the plunger protrudes by the urging force of the urging member, and the medal sorter 21 returns and closes the medal allocating port 20.

  The medal distributor 21 always closes the medal distribution opening 20, and the medal M flows down the medal guide rod 17. Then, the medal counter 18 counts the medal M of the predetermined maximum number of insertions and the maximum number of credits reserved (50 pieces) per game, or a start switch (not shown) by operating the start lever 7. When is turned on, the solenoid is excited to attract the plunger, the medal distributor 21 is swung to open the medal distribution port 20, and the medal M flowing down the medal guide rod 17 is discharged to the medal distribution port 20. Let These medals M are discharged to the medal storage tray 10. Thereafter, when the game is over, the solenoid is demagnetized and the plunger protrudes, the medal sorter 21 is returned, and the medal sorter 20 is closed.

  A passing direction detection device 23 for detecting the passing direction of the medal M is provided on the upstream side of the medal distributor 21. In the passing direction detection device 23, two optical sensors 24a and 24b are arranged in parallel along the flow direction of the medal M and are detected in the same manner as the detection of the passing direction of the medal M performed by the medal counter 18. I do.

  That is, when the medal M flows down normally, the upstream optical sensor 24a first detects the medal M, and then the downstream optical sensor 24b detects the medal M. On the other hand, when an illegal act such as pulling back the inserted medal M is performed, the medal M moves from the downstream side toward the upstream side. First, the downstream optical sensor 24b is operated by the medal M. Then, the upstream optical sensor 24a detects the medal M. In this case, in addition to the medal M, the same operation is performed for fraud using the shading plate B for fraud. Therefore, based on the detection of the passing direction detecting device 23, the case where the passing direction detecting device 23 detects the normally inserted medal M is stored and compared with the stored normal detecting signal. If it is different from the signal, it is determined that an illegal act has been performed.

  The medal guide rod 17 between the passing direction detecting device 23 and the receiving port 15 is provided with a horizontally long rectangular different diameter medal sorting opening 25 on the side wall. The different diameter medal sorting opening 25 has a lower side positioned slightly above the bottom surface of the medal guiding rod 17 and an upper side positioned slightly below the height (diameter) of the regular medal M flowing down the medal guiding rod 17. doing. By adjusting the position of the upper side, the diameter of the medal M to be selected can be adjusted.

  Therefore, the regular medal M flowing down the medal guide rod 17 passes through the different diameter medal sorting opening 25. On the other hand, the different diameter medal having a diameter smaller than the regular medal M falls from the different diameter medal selection opening 25 and is discharged to the medal storage tray 10 when passing through the different diameter medal selection opening 25. The different diameter medal having a smaller diameter than the regular medal M is selected by the above-mentioned different diameter medal sorting opening 25, but the different diameter medal having a larger diameter than the regular medal M is the medal insertion slot 4. Can be selected by slightly making the size of the medals slightly larger than the regular medal M.

  Therefore, when the medal M is inserted into the medal insertion slot 4, the inserted medal detecting device 14 detects the game and the game can be played. Then, when the start lever 7 is actuated, the reels 2 rotate all at once, and when the respective stop buttons 8 are pressed for a predetermined time or when the reels 2 are stopped respectively, at this time, if the same information is aligned horizontally or diagonally, A predetermined number of medals M are discharged to the medal storage tray 10 through the medal discharge port 9 according to the information. Note that when there is one medal M, there is only one line on which the information is arranged, but when there are two or three, the number increases to three or five.

  In the present invention, the anti-fraud tool A for preventing the intrusion of the fraudulent shading plate B is attached to the medal slot 4. The fraud prevention tool A is formed of, for example, a hard metal material or a hard synthetic resin material, and has an arch-like flat baffle member 26 as shown in FIG. Mounting plate 27. The baffle member 26 is projected and substantially orthogonal to the guide plate 6 and is shaped to surround both sides and the upper portion of the guide plate 6 with a slight gap.

Then, as shown in FIGS. 3 and 4, an adhesive is applied to the back side of the mounting plates 27, 27, and the mounting plates 27, 27 are surrounded by the baffle member 26 so as to surround the guide plate 6. It adheres in a non-peelable manner. At this time, the baffle member 26 is arranged along the outer peripheral edge of the guide plate 6 and surrounds the outer peripheral edge and protrudes a predetermined width toward the medal insertion slot 4 so as to surround the medal insertion slot 4.
The front edge 26a of the baffle member 26 is substantially parallel to the front surface 6a of the guide plate 6. The distance L between the front surface 6a of the guide plate 6 and the front edge 26a of the baffle member 26 having the predetermined width is 7 to 10 mm. preferable. The baffle member 26 may not have a flat plate shape but may have a circular or elliptical cross section, for example.

  In this way, the anti-fraud tool A of the present invention surrounds the medal slot 4 with the baffle member 26, so that the medal slot can be inserted from an oblique direction as well as directly above the medal slot 4 as shown in FIG. Even if the fraudulent light-shielding plate B tries to enter the opening 4, the baffle member 26 is obstructed and the illegal light-shielding plate B is prevented from entering the medal slot 4. In particular, since the front end edge of the medal slot 4 is formed in an arc shape, the fraudulent shading plate B cannot enter the medal slot 4 from the front side. Thereby, the illegal act by the light-shielding plate B for fraud is prevented.

  The fraud prevention tool A is molded separately from the slot machine S. However, when the base 5 or the stepped portion 3 is molded, the slot machine S may be assembled by molding it together. In this way, a slot machine S equipped with the anti-fraud tool A can be prepared from the beginning.
