Description

  The present invention relates to a gaming machine such as a slot machine.

  A gaming machine such as a slot machine allows a player to enjoy a game by inserting a predetermined number of medals (game media) into the gaming machine. The medals necessary for the game can be borrowed by a medal lending machine provided in the game hall, and the game can be started by inserting medals into the medal slot of a desired gaming machine.

  The inserted medals are selected by a medal selector inside the gaming machine (defective medals are returned), and the number of inserted medals is counted. This count value is treated as the number of inserted medals, and the player can enjoy the game within this range. Even after the medal is inserted, it is possible to request the return of the inserted medal if it is before the credit is consumed by the game. A cancel button is provided on the front panel of the gaming machine for the return operation (see reference numeral 138 in FIG. 1).

  FIG. 12 is a perspective view of a conventional medal selector provided in the slot machine. FIG. 13 is a diagram for explaining the operation of the conventional medal selector. 12 and 13A, 1 is a medal selector, 11 is a downwardly inclined medal passage, 12 is a medal exit of the medal selector 1, and S1 and S2 are photointerrupters provided in the medal passage 11 (for medal detection). Sensor). M indicates the inserted medal. The medal M inserted from the upper part of the medal selector 1 falls along the medal passage 11, the traveling direction thereof is changed to a slant sideways, and is discharged from the medal outlet 12. Note that irregular medals of different sizes fall in the middle of the medal passage and return to the medal return slot.

  In the vicinity of the medal outlet 12, two medal sensors S1, S2 are provided side by side along the direction in which the medal advances. The detection of medals is performed according to the detection order of the two sensors. FIG. 13B shows a timing chart of output signals of the sensors S1 and S2 when the medal M passes. In the signal of FIG. 13B, a high level is positive logic indicating a medal passing state. The phase of the signal of the sensor S1 provided on the front side is more advanced than that of S2. The passage of medals sent without being blocked on the way is detected by the sensors S1, S2. Since S1 and S2 are provided adjacent to each other, it is possible to detect the passing speed and passing direction of medals, and based on these, not only the number of medals but also illegal acts using medals backflow or celluloid are detected. can do. Further, by providing the medal sensors S1 and S2 on the side far from the medal entrance, it is difficult to cheat.

  Fraudulent acts on game machines (so-called goto acts) are increasing and the damage caused by this is also increasing. Moreover, fraudulent methods have become more sophisticated over time. As one of them, there is a technique of inserting a device for cheating from the medal insertion slot, illegally operating the medal counting function of the medal selector and malfunctioning, and illegally obtaining a large number of credits even if no medal is inserted. is there.

  Inserting an instrument with two light emitting elements such as infrared LEDs at the tip and blinking them toward the sensors S1 and S2, the signal shown in FIG. is there. Although it is possible to play a game with credits obtained illegally, in many cases it seems that a medal is received by a cancel button. There are many cases where the discovery of fraud against medal selectors is often delayed, and there is concern about the spread of damage.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine, a gaming machine fraud prevention method, and a program that can prevent the dishonest act.

  According to the present invention, a medal selector for counting medals inserted from a medal slot, a sensor provided in the medal selector for detecting medals, and counting the number of medals inserted based on an output of the sensor. In a gaming machine including a control unit, a medal passing speed calculation unit that calculates a medal passing speed based on a detection signal of the sensor, a reference medal passing speed storage unit that stores a reference medal passing speed in advance, and the medal And a fraud detection unit that determines fraud by comparing the medal passage speed calculated by the passage speed calculation unit with the reference of the reference medal passage speed storage unit.

  For example, the medal passing speed calculation unit calculates the medal passing speed based on the formula: medal passing speed = medal width at the sensor position ÷ time ta, where ta is the pulse width of the detection signal of the sensor. .

  When the medal selector is provided with a plurality of sensors, for example, the medal passing speed calculation unit is expressed by the formula: medal passing speed = interval between a plurality of sensors / time when a time difference between detection signals of the plurality of sensors is tb. Based on tb, the passing speed of medals is calculated.

When a plurality of passage speeds are obtained by the medal passage speed calculation unit,
From the viewpoint of preventing erroneous detection, preferably, the fraud detection unit selects and compares the minimum one of the plurality of passage speeds when determining whether or not the medal passage speed is larger than a reference value, When it is determined whether the medal passing speed is smaller than the reference value, the maximum one of the plurality of passing speeds is selected and compared. From the viewpoint of fraud prevention, preferably, the fraud detection unit selects and compares the maximum of the plurality of passage speeds when determining whether or not the medal passage speed is larger than a reference value, When determining whether or not the medal passing speed is smaller than the reference value, the smallest one of the plurality of passing speeds is selected and compared.

  According to the present invention, a medal selector for counting medals inserted from a medal slot, a sensor provided in the medal selector for detecting medals, and counting the number of medals inserted based on an output of the sensor. In a gaming machine including a control unit, a medal insertion interval calculation unit that calculates a medal insertion interval based on a detection signal of the sensor, a reference medal insertion interval storage unit that stores a reference medal insertion interval in advance, and the medal And a fraud detection unit that determines fraud by comparing the medal insertion interval calculated by the insertion interval calculation unit with the reference of the reference medal insertion interval storage unit.

  For example, the reference medal insertion interval storage unit stores a value corresponding to the diameter of one medal as the reference.

According to the present invention, a medal selector for counting medals inserted from a medal slot, a sensor provided in the medal selector for detecting medals, and counting the number of medals inserted based on an output of the sensor.

A cancel switch (also referred to as a cancel button) 138 is for requesting the return of inserted medals.

  As shown in FIG. 2, the slot machine main body 120 is fixed to the inner bottom surface, stores a plurality of medals therein, and stores the stored medals at a payout port 135 provided on the front surface of the front door 130. A hopper device 121 for paying out the sheets one by one is installed. An upper portion of the hopper device 121 is provided with a hopper tank 122 that opens upward and stores a plurality of medals therein. Inside the slot machine main body 120, a reel unit 203 including three rotating reels is installed at a position where the game display unit 131 comes when the front door 130 is closed.

  As shown in FIG. 2, the medal selector 1 is attached to the back side of the front door 130 on the back side of the medal slot 132 provided on the front surface of the front door 130. This medal selector 1 rolls the medal toward the hopper device 121 while detecting the passage of the medal inserted from the medal insertion slot 132, and has a different diameter medal or iron or iron whose outer diameter is different from the predetermined dimension. This is an apparatus for selecting and removing illegal medals made of an alloy and selecting and eliminating a predetermined number or more of medals that can be inserted per game.

  Further, as shown in FIG. 2, a lead-out path 136 that covers the lower side and communicates with the payout port 135 of the front door 130 is provided below the medal selector 1. The medals distributed by the medal selector 1 are returned to the player from the payout port 135 via the derivation path 136.

A square window-like display window facing the player side is formed at the center and upper part of the casing of the slot machine. In the center of the central display window, a symbol display window through which the symbols of the three rotating reels can be seen is formed. The start switch 134 is a lever located obliquely below the rotating reel, and starts driving the reel unit on condition that a game medal is inserted. The reel unit is stopped from being driven by a stop switch. The reel unit is composed of three rotating reels. Each rotating reel includes a rotating drum made of a synthetic resin and a tape-like reel tape attached around the rotating drum. A plurality of (for example, 21) symbols are displayed on the outer peripheral surface of the reel tape.

  FIG. 3 shows a functional block diagram of the slot machine. Reference numerals 200 and 201 denote a main board and a sub board, each incorporating a CPU. The main board 200 performs medal insertion, payout, reel control, winning process, and the like. The sub-board 201 performs processing such as effect display. An operation unit 202 includes switches such as a start switch 134, a stop switch 140, and a bet switch. A reel unit 203 includes three rotating reels. An effect display unit 204 includes a game display unit 131, internal illumination of a reel, a liquid crystal display device, a speaker, and the like. The effect display unit 204 notifies the winning combination and the pressing order.

  Reference numeral 1 denotes a medal selector, and S1 and S2 are medal detection sensors provided in the medal selector 1. The sensors S1 and S2 are a sensor (for example, a photo interrupter) that includes a light emitting element and a light receiving element (not shown) and outputs a detection signal by shielding the optical path from the light emitting element to the light receiving element when a medal is present between them. .

  Reference numeral 20 denotes a medal passage speed calculation unit that calculates a medal passage speed based on one or both detection signals of the sensor S1 or S2. Reference numeral 21 denotes a reference medal passage speed storage unit that stores a standard medal passage speed in advance. This is a fraud detection unit that compares the medal passage speed calculated by the medal passage speed calculation unit 20 with the reference of the reference medal passage speed storage unit 21 and determines that it is a fraudulent action.

  The error signal output by the fraud detection unit 22 is input to the main board 200 and is output to the outside as necessary. The medal passage speed calculation unit 20, the reference medal passage speed storage unit 21, and the fraud detection unit 22 are realized by hardware (for example, a counter or a shift register) or software, and may be provided independently as shown in FIG. Alternatively, it may be provided in the main board 200 or the medal selector 1 (the same applies to the second and third embodiments of the invention regarding these points).

  An illegal act of misrecognizing with a board mounted with an LED in which the light receiving element of the medal selector 1 is inserted from the outside is based on hardware such as a microcomputer and is much more medal than the actual medal passing speed. The input speed is often fast. Therefore, the medal passing speed is calculated, and when this is significantly different (fast) from the standard passing speed, it is possible to determine that it is an illegal act. In addition, since an illegal act using a simple cell plate or the like is slower than the passing speed of a medal, it can be determined as an illegal act when the medal passing speed is significantly different (slow) from the standard passing speed. The first embodiment of the invention is based on such a viewpoint.

  The operation of the apparatus / method according to the first embodiment of the present invention will be described with reference to the flowchart of FIG. 4 and the timing chart of FIG.

S11: A signal is received from the medal sensor.

S12: The medal passing speed is calculated based on the received medal detection signal. The calculation of the medal passing speed will be described with reference to FIG.

  The medal passing speed is calculated by calculating the case-specific medal speed from the relative positions of the two sensors S1, S2 and the medals, and the relative positions of the sensors, and the case where the medal passing speed deviates significantly from the calculated value. The medal speed of a general selector is approximately 1 mm / ms.

Signals from the sensors S1 and S2 are as shown in FIG. 5A, and one pulse indicates the passage of one medal. The pulse widths ta and ta ′ are the time required for one medal to pass through one sensor, and the time difference tb between the sensors S1 and S2 is the downstream side after one medal reaches the upstream sensor S1. This is the time until the sensor S2 is reached. The pulse widths ta and ta ′ correspond to the medal width (more precisely, the width when the medal is cut at the sensor height), and the time difference tb corresponds to the interval between the sensors S1 and S2. Therefore, the passing speed of medals can be obtained by the following three formulas.
(1) Medal passing speed = interval (distance) between sensors S1 and S2 ÷ time difference tb
(2) Medal passing speed = medal width at the position of sensor S1 ÷ time ta
(3) Medal passing speed = medal width at the position of sensor S2 / time ta ′

  In step S12, the medal passing speed may be calculated by any one of the above (1) to (3). Or you may obtain | require the average of said (1)-(3), and may select the largest or the minimum thing among these. The medal passage speed may be used or changed according to the determination contents of steps S13 and S14. For example, to prevent false detection, select the smallest value when determining whether the medal passing speed is significantly higher than the reference value, and select the maximum value when determining whether the medal passing speed is significantly lower than the reference value. Choose one. Or, from the standpoint of reliably detecting fraud and effectively preventing fraud, contrary to the above case, when determining whether the medal passing speed is significantly higher than the reference value, the maximum one is used. When it is selected and it is determined whether the medal passing speed is significantly smaller than the reference value, the smallest one is selected.

S13: The medal passage speed is compared with a reference value. The reference value is stored in advance in the reference medal passage speed storage unit 21. The reference value is set for each model or gaming machine, but the reference medal passing speed is approximately 1 mm / ms as described above.

S14: It is determined whether the medal passing speed is significantly higher than the reference value or whether the medal passing speed is significantly lower than the reference value. The former corresponds to an illegal act using a tool using an LED or the like, and the latter corresponds to an illegal act using a so-called cell plate. From the viewpoint of preventing erroneous detection, it is preferable not to determine that the reference value is larger or smaller than the reference value, but also to determine the degree thereof (for example, faster than 200% of the reference value, more than 50% of the reference value). Is too slow).

S15: When the medal passing speed is significantly different from the reference value (YES in S14), it is determined as an illegal act, an error flag is set, and an error signal is output.

S16: Stop accepting games and paying out medals so as not to give profits to fraudsters. This state continues until the hall attendant resets the gaming machine.

  According to the first embodiment of the invention, the medal passing speed calculation unit and the reference medal passing speed storage unit are provided as means for discriminating when the sensor of the medal selector is erroneously operated with a cheating tool and when the medal is actually inserted. Since it is provided, fraudulent acts can be detected. When cheating is detected, an error is notified, and the game reception and the medal payout are stopped, so that it is possible to prevent the cheating person from being profited.

Embodiment 2 of the Invention
As described above, fraudulent acts such as misrecognition by a substrate mounted with an LED having the light-receiving element of the medal selector 1 entered from the outside, using hardware such as a microcomputer as described above, are compared with the actual medal passing speed. In many cases, the medal insertion speed is much faster. Therefore, the interval between the detection signals of the medals is very short, that is, the insertion interval of the medals is significantly shorter than that in the normal case. Normally, the insertion interval is not less than the medal diameter. It can be determined that this is an illegal act. In the second embodiment of the present invention, based on such a viewpoint, the distance between medals unique to the case is calculated in advance, and a case where the distance greatly deviates from the value is detected as an illegal act.

  FIG. 6 shows a functional block diagram of the slot machine according to the second embodiment of the invention. 6, parts that are the same as or correspond to those in FIG. 3 are given the same reference numerals, and descriptions thereof are omitted. 23 is a medal insertion interval calculation unit for calculating medal insertion intervals based on one or both detection signals of the sensors S1 and S2, 24 is a reference medal insertion interval storage unit for storing standard medal insertion intervals in advance, and 25 is This is a fraud detection unit that determines a fraud when the medal insertion interval calculated by the medal insertion interval calculation unit 23 is significantly different from the reference in the reference medal insertion interval storage unit 24.

  The operation of the apparatus / method according to Embodiment 2 of the present invention will be described with reference to the flowchart of FIG. 6 and the timing chart of FIG.

S21: A signal is received from the medal sensor.

S22: The medal insertion interval is calculated based on the received medal detection signal. The calculation of the medal insertion interval will be described with reference to FIG.

Signals from the sensors S1 and S2 are as shown in FIG. 8A, and one pulse indicates the passage of one medal. The pulse intervals tc and tc ′ are intervals at which the sensor detects the medals one after another when medals are continuously inserted, and are related to the physical distance between the medals and the medal and the passing speed thereof. Specifically, there is the following relationship.
Sensor physical distance between medals = medal passing speed x pulse interval tc, tc '

  The passing speed of medals is measured in advance. Even when the distance between medals is the smallest, the physical distance between medals in the sensor cannot be smaller than the diameter of the medals. In steps S23 and S24, the physical distance between medals in the sensor obtained by the above formula is compared with the diameter of the medals. In the case where the minimum values of the pulse intervals tc and tc ′ are stored in the reference medal insertion interval storage unit 24, the measurement times tc and tc ′ can be directly compared with the reference values without obtaining the distance. .

S23: The medal insertion interval is compared with a reference value. The reference value is stored in advance in the reference medal insertion interval storage unit 24. When comparing medal insertion intervals by distance, medal diameter is stored as a reference value. When comparing the medal insertion interval by time, if the insertion interval is the shortest in the normal use state as a reference value, for example, a value obtained by the following equation is stored.
Standard medal insertion interval tc, tc '=
The medal width at the positions of sensors S1 and S2 ÷ medal passing speed when medals are continuously inserted

S24: It is determined whether the medal insertion interval is significantly smaller than the reference value. If this is the case, it is determined that an illegal act using a tool using an LED or the like has been performed. From the viewpoint of preventing erroneous detection, it is preferable not to determine that the value is simply smaller than the reference value, but also to determine the degree thereof (for example, less than 50% of the reference value).

S25: When the medal insertion interval is significantly different from the reference value (YES in S24), it is determined as an illegal act, an error flag is set, and an error signal is output.

S26: Stop accepting games and paying out medals so as not to give profits to fraudsters. This state continues until the hall attendant resets the gaming machine.

  According to the second embodiment of the invention, the medal insertion interval calculation unit and the reference medal insertion interval storage unit are provided as means for discriminating between the case where the sensor of the medal selector is erroneously operated with a fraudulent tool and the case where the medal is actually inserted. Since it is provided, fraudulent acts can be detected. When cheating is detected, an error is notified, and the game reception and the medal payout are stopped, so that it is possible to prevent the cheating person from being profited.

Embodiment 3 of the Invention
As described above, fraudulent acts such as misrecognition by a substrate mounted with an LED having the light-receiving element of the medal selector 1 entered from the outside, using hardware such as a microcomputer as described above, are compared with the actual medal passing speed. Not only is the medal insertion speed much faster, but it is counted continuously and reaches the upper limit of storage at once. In addition, there is an easy specification that continues to be inserted even when the medal insertion exceeds the upper limit of the number of stored sheets, and the operation differs from that of a human action. Actually, the number of medals that a player can insert at a time is not so large, and is less than the maximum number that can be held by a player or the maximum number that can be placed near the medal slot. In addition, when the right hand and the left hand are used alternately and continuously inserted, it is necessary to change medals, and an interval is generated at that time. Actually, it is general that about 20 to 30 medals can be placed at the entrance of the medal slot, and the number of cards that can be held by the player is also about that. An additional time interval in seconds is required for additional input. Therefore, when medals are continuously inserted beyond the limit that the player can insert at a time, it can be determined that an illegal act has been performed. It can be determined that this is an illegal act. The third embodiment of the invention calculates the number of consecutively inserted medals based on such a viewpoint, and detects a case where the medal deviates significantly from a standard value as an illegal act.

  FIG. 9 is a functional block diagram of the slot machine according to Embodiment 3 of the invention. 9, parts that are the same as or correspond to those in FIG. 3 are given the same reference numerals, and descriptions thereof are omitted. 26 is a medal continuous number calculating unit that calculates the number of consecutively inserted medals based on the detection signal of one or both of the sensors S1 and S2, and 27 is a reference medal continuous number storing unit that stores a standard number of continuously inserted medals in advance. 28 is a medal continuous insertion interval calculation unit that calculates a time interval between consecutive insertions of medals based on detection signals of one or both of the sensors S1 and S2, and 29 is a standard time interval of continuous insertion of medals in advance. The reference medal continuous insertion interval storage unit 30 stores the medal continuous insertion number calculated by the medal continuous number calculation unit 26 when compared with the standard of the reference medal continuous number storage unit 27 and is illegal when It is a cheating detection part which judges that.

  The operation of the apparatus / method according to Embodiment 3 of the present invention will be described with reference to the flowchart of FIG. 10 and the timing chart of FIG.

S31: A signal is received from the medal sensor.

S32: The continuous medal number is calculated based on the medal detection signal received from the sensor S1 or the sensor S2. The calculation of the medal insertion interval will be described with reference to FIG.

  Signals from the sensors S1 and S2 are as shown in FIG. 11A, and one pulse indicates the passage of one medal. Pulses during the period td and td ′ indicate the number of consecutive medals. te and te ′ indicate the interval between continuous input and continuous input. By the way, when one pulse is generated and the next pulse is generated again (when at least two medals are inserted), whether or not these are continuous is whether the interval between the pulses is shorter than a predetermined time. Judge with.

For example, the following processing is performed to calculate the continuous medal number.
(A) First, a medal detection time is acquired and compared with the previous medal detection time stored in advance, and the following processes (b) and (c) are performed. When this processing is executed, the medal detection time acquired this time is stored as the previous medal detection time, and the same processing is repeated. In FIG. 11A, tP and tP ′ indicate the detection time of the medal acquired this time, and tL and tL ′ indicate the previous medal detection time. The current / previous detection time (tL, tP) is updated each time a new pulse is received (tP is overwritten with the old tL, and the detection time of the new pulse becomes tP). In FIG. 11A, tP and tL mean the current medal detection time and the previous medal detection time when the pulse P is received, and tP ′ and tL ′ are the current medal detection time when the pulse P ′ is received. This means the medal detection time and the previous medal detection time.
(B) The medal insertion interval is smaller than a predetermined value (this case corresponds to (tP-tL) in FIG. 11A).
-> Continuous input, continuous number + 1
(C) The medal insertion interval is larger than a predetermined value (this case corresponds to (tP′-tL ′) in FIG. 11A).
-> It is determined that it is not continuous insertion. If it is determined that it is not continuous insertion, the number of continuous medals up to the previous time (number of pulses in td, td ') is determined as the continuous number of medals. Make a judgment. After that, clear the continuous number and prepare for the next continuous loading.
The predetermined time for determining whether or not it is continuous is approximately 1 second.

S33: The medal continuous insertion interval is calculated based on the medal detection signal received from the sensor S1 or the sensor S2. The calculation of the medal insertion interval will be described with reference to FIG. In FIG. 11A, pulses in the period of te and te ′ indicate the medal continuous insertion interval. The medal continuous insertion interval is performed as follows, for example, when tL ′ is a time point when the continuous insertion is finished (see (c) above) and tP ′ is a time point when the next continuous insertion is started.
(D) The interval (tP'-tL ') in (c) above is the medal continuous insertion interval te'.

S34: The continuous medal number is compared with the reference value. The reference value is stored in advance in the reference medal continuous number storage unit 27. The standard number of consecutive medals is about 20-30.

S35: It is determined whether the continuous medal number is significantly larger than the reference value. If this is the case, it is determined that an illegal act using a tool using an LED or the like has been performed. From the viewpoint of preventing erroneous detection, it is preferable not to determine that the value is simply smaller than the reference value, but also to determine the degree thereof (for example, greater than 200% of the reference value).

S36: The medal continuous insertion interval is compared with a reference value. The reference value is stored in advance in the reference medal continuous insertion interval storage unit 29. The standard medal continuous insertion interval is approximately 1 second or more. It is considered that this time is required to change and insert medals.

S37: If the medal continuous insertion interval is short and then continuous insertion is started again, it is determined that an illegal act has been made. From the standpoint of preventing false detection, when the medal continuous insertion interval is short, the sum of the consecutive medal insertion number after the interval plus the previous medal continuous insertion amount exceeds the reference medal continuous number It is determined that an illegal act has been made. In step S32, if it is impossible to change medals even if there is an interval, the consecutive number may be calculated by ignoring the interval.

S38: When the number of consecutive medals is greater than the reference value (YES in S35), and when the continuous insertion of medals is short and then continuous insertion is started again (YES in S37), it is determined as an illegal act and an error flag is set. Set and output an error signal.

S39: Stop accepting games and paying out medals so as not to give profits to fraudsters. This state continues until the hall attendant resets the gaming machine.

  According to the third embodiment of the invention, the medal continuous number calculating unit, the medal continuous inserting interval calculating unit, and the means for discriminating when the sensor of the medal selector is erroneously operated with a fraudulent tool and when the medal is actually inserted, Since these reference storage units are provided, fraudulent acts can be detected. When cheating is detected, an error is notified, and the game reception and the medal payout are stopped, so that it is possible to prevent the cheating person from being profited.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  Further, in the present specification, the term “unit” does not necessarily mean a physical means, but includes a case where the function of each unit is realized by software. Furthermore, the function of one part may be realized by two or more physical means, or the function of two or more parts may be realized by one physical means.
