Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to a technique for preventing fraudulent acts on the gaming 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 medals inserted (also called credits. Those medals that have already been inserted and are not used in the game can be returned by pressing the settlement switch). The player can enjoy the game. 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 settlement switch is provided on the front panel of the gaming machine for the return operation (see reference numeral 138 in FIG. 1).

  FIG. 9 is a perspective view of a conventional medal selector provided in the slot machine. FIG. 10 is a diagram for explaining the operation of the conventional medal selector. 9 and 10 (a), 1 is a medal selector, 11 is a downwardly inclined medal passage, 12 is a medal discharge port of the medal selector 1, and S1 and S2 are photointerrupters (medal detection detection) provided in the medal passage 11. Medal 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 discharge port 12. Note that irregular medals of different sizes fall in the middle of the medal passage and return to the medal return slot. 9 and 10 is a medal sensor composed of photointerrupters S1 and S2 (S1 and S2 are combined to function as a medal sensor), and 1b is closer to the medal slot of the medal passage 11 than the medal sensor 1a. It is a blocker that discharges a medal that is provided and rolls in the medal passage 11 to a medal payout outlet before reaching the medal sensor 1a. Reference numerals 1a and 1b are used in the description of embodiments of the invention described later.

  Two medal sensors S1 and S2 are provided in the vicinity of the medal discharge port 12 along the direction in which the medal proceeds. The detection of medals is performed according to the detection order of the two sensors. FIG. 10B shows a timing chart of output signals of the sensors S1 and S2 when the medal M passes. In the signal of FIG. 10B, 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. When the sensors S1 and S2 as shown in FIG. 10B are output, the output of the sensors is generated.

  Since the two sensors 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 the reverse flow of medals, celluloid, etc. Can be detected. Further, by providing the medal sensors S1 and S2 on the side far from the medal entrance, it is difficult to cheat.

A gaming machine (slot machine) according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of the slot machine with the front door closed, and FIG. 2 is a front view of the slot machine with the front door opened 180 degrees.

  1 and 2, reference numeral 100 denotes a slot machine. As shown in FIG. 1, the slot machine 100 can be opened and closed by a hinge or the like on the slot machine main body 120 and one side of the front surface of the slot machine main body 120. And a front door 130 attached thereto. As shown in FIG. 1, a game display unit 131 is provided substantially in the center of the front door 130, and a medal insertion slot 132 for a player to insert medals is provided at the lower right corner of the game display unit 131. Provided on the further left side of the medal insertion slot 132 is a reject button 133 for forcibly discharging the clogged medals inserted from the medal insertion slot 132 to the outside of the slot machine 100.

  A start switch 134 for starting a game is provided at the lower left of the game display unit 131, and three stop buttons 140 are provided corresponding to the three reels. A medal payout port 135 is provided at the center of the lower end of the front door. When a game medal is inserted into the medal slot 132 or the start switch 134 is operated on condition that the bet switch 137 is operated, the three reels start to rotate and the game starts. A settlement switch (also referred to as a settlement button) 138 is used to request the return of unused 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 player who wants to enjoy a game with a slot machine can first borrow a medal as a game medium from a medal lending machine (not shown) or the like, and insert a medal directly into the medal slot 132 of the medal slot device. 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 is a functional block diagram of the gaming machine according to the embodiment of the invention.
In FIG. 3, reference numerals 200 and 201 denote a main board and a sub board, each incorporating a CPU, ROM and RAM, respectively.

  The main board 200 performs medal insertion control, payout control, reel control, winning process, and the like. The processing executed by the main board 200 will be described in detail later.

  The sub-board 201 is for receiving a command signal from the main board 200 and notifying the result of the internal lottery and performing various effects. The sub-board 201 includes a CPU that performs a control operation in accordance with a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results.

  An operation unit 202 includes switches such as a start switch 134, a stop switch 140, and a bet switch 137.

  Reference numeral 204 denotes an effect display unit including internal lighting of the reel of the game display unit 131, electrical decoration, a liquid crystal display device, a speaker, and the like. The effect display unit 204 notifies the winning combination and the pressing order.

The medal selector 1 includes a medal sensor 1a for detecting inserted medals (the same as the photointerrupters S1 and S2 in FIGS. 9 and 10), and a blocker 1b for discharging the inserted medals to the medal payout opening 135. (Same as the blocker 1b of FIG. 9). The medal sensor 1a is an optical sensor (for example, a photo interrupter) provided in a medal passage (see FIG. 9) for guiding a medal inserted from the medal insertion slot 132 to the hopper tank 122.
The blocker 1b of FIG. 9 has a structure that supports the upper end of a regular medal that flows down when the gaming machine is powered on and the blocker is not operating. When the blocker is operated or when the power of the gaming machine is turned off, the blocker 1b moves to open its tip (the portion located at the upper end of the medal passage 11), and the upper end of the flowing medal cannot be supported. Since the medal passage 11 is inclined, the medal will fall to the medal payout port 135 unless it is supported.
The blocker 1b may have a structure other than that shown in FIG. For example, the blocker 1b is a protrusion provided in the medal passage, and is advanced and retracted by a drive unit (not shown) such as a solenoid. The blocker 1b is normally drawn in from the medal path, but when the driving unit is driven based on the control of the main board 200, the blocker 1b protrudes into the medal path and removes medals and foreign objects in the medal path. It pops out of the passage. The blocker 1b is provided on the upstream side of the medal sensor 1a, and when the blocker 1b is operated, the medal is returned from the medal payout opening 135 without being detected by the medal sensor 1a.

  The reel unit 203 includes three rotating reels 203a and a stepping motor 203b that rotates each of them.

  The hopper device 121 includes a rotating disk (not shown) for paying out stored medals one by one to a payout opening 135 provided on the front surface of the front door 130, and a hopper motor 121a for rotating the disk.

  Although the operation unit 202 includes a plurality of switches, FIG. 3 clearly shows only the start switch 134, the stop switch 140, and the bet switch 137 that are directly related to the embodiment of the invention.

  The start switch 134 is supported by, for example, a spherical knob 134a directly touched by the player and a predetermined fulcrum, and swings away from the reference position from a predetermined reference position in response to the player's operation. A lever 134b that moves to a position and a start switch sensor 134c that detects whether the lever 134b is at the reference position are included. The lever 134b is made of, for example, a rod-shaped member.

  A lever is a rod and is a member, typically a bar, that can freely rotate around an axis passing through a certain point. A knob is a handle, and is a protruding part of an object that is attached to touch with a hand.

  The main board (control unit) 200 is for performing an internal lottery based on an output signal of the start switch 134, and processing such as reel rotation / stop and medal payout. The main board 200 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The main board 200 includes a timer TM. The timer TM is realized by hardware such as an IC or software by a program executable by the CPU.

  Specifically, the main board 200 executes the process shown in FIG.

S1: Processing related to medal insertion detection The output of the medal sensor 1a is monitored, and it is determined that a medal is inserted when a signal indicating that a medal is inserted (for example, a signal indicating that light is blocked by a photo interrupter) is received. Then, the number of inserted medals is increased (generally, it is increased by 1).
If it is determined that medals have been inserted, a bet is made up to a predetermined number, and credits are credited for the amount exceeding the predetermined number.

S2: Processing related to pressing of the bet switch When the output of the bet switch 134 is monitored and a signal indicating that it has been operated is received, the number of medals bet is increased and the number of credits is decreased accordingly. When the number of credits is zero, or when a predetermined number of bets have already been made, nothing is done even if the bet switch 134 is operated (the output of the bet switch 134 is ignored).

S3: Process related to start switch depression This process includes the following two processes.
(1) Internal lottery process When a required number of medals for a game are bet, a random number value is acquired based on a signal from the start switch sensor 134c of the start switch 134, and a winning determination is performed based on the random value. When the random value is a value for winning a predetermined combination, information (flag) to that effect is written in the RAM.
(2) Rotating reel rotation processing Based on the signal from the start switch sensor 134c of the start switch 134, the three stepping motors 203b are driven to rotate the three rotating reels 203a.

S4: Processing related to pressing the stop switch (rotating reel stop processing)
The outputs of the three stop switches 140 are monitored, and when the rotating reel 203a is rotating, when a signal indicating that any one of them is operated is received, the corresponding rotating reel 203a according to the result of the internal lottery process. Stop. This process is continued until all the three rotary reels 203a are stopped. When the stop switch 140 is not operated, the rotation of the three rotary reels 203a is automatically stopped when a predetermined time has elapsed.

  S3: When the result of the internal lottery process (1) in the process related to pressing the start switch is out of place, for example, a predetermined symbol is not set in the process of S4 (so-called kicking), and a win (flag) Is set so that a predetermined symbol is aligned (so-called pull-in) on condition that the stop switch 140 is pressed at a predetermined timing. In other words, only when winning in the internal lottery process, medals are paid out by winning a winning pattern under a predetermined condition, but when not winning, no matter how the stop switch 140 is operated, the medal Will not be paid out. This is to keep the medal payout at a certain probability.

  The ROM of the main board 200 stores game processing procedures executed on the gaming machine as a sequence program, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like. Yes. The winning probability table is divided so as to divide the extracted random number into each winning mode, and stores data that divides the random number extracted from a certain range of numerical values into each winning mode. That is, the winning probability table has an area divided for each winning mode corresponding to the entire area of random numbers. For example, a range of 0 to a certain number is divided into a plurality, one division (region) is excluded, and the other division (region) is set as winning 1, winning 2,. The extracted random number data is collated with each of the winning determination area data divided for each winning mode in all areas corresponding to the random number, and the winning corresponding to the winning mode to which the extracted random number data belongs is determined. The For example, it is checked which category (region) in the winning probability table the extracted random number value is, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to the category (area) out of the winning determination table 5, it is determined as “out”. As described above, for example, when the evaluation of the lottery process is out of place, it is set so that predetermined symbols are not aligned (so-called kicking), and in the case of winning, it is predetermined on the condition that the stop switch is pressed at a predetermined timing. Are set so that the symbols are aligned (so-called pull-in).

S5: Processing when all reels are stopped (winning determination processing)
When all the reels are stopped by the process of S4, it is determined whether or not a predetermined combination is won. Specifically, it is determined whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed.

S6: Payout process When it is determined that the winning is confirmed by the process of S5, a medal corresponding to the winning symbol is paid out. The main board 200 drives the hopper motor 121a to pay out medals, and stops driving the hopper motor 121a when a predetermined number of medals are paid out.

  The internal lottery process and the winning determination process occur under the probability according to the data setting of the winning probability table and the stop control of the symbol is performed. The total medal payment rate during business hours is maintained almost constant.

  FIG. 5 shows a flowchart of the fraud determination process according to the embodiment of the invention. The fraud determination process is executed by the main board 200, for example. Hereinafter, the processing procedure will be described with reference to this figure.

S11: The number of bets is acquired.
As described above, the number of inserted medals increased by operating the bet switch 134 is acquired. The maximum number of bets is usually three.

S12: Acquire the number of credits.
The number of medals detected by the medal sensor 1a corresponds to the credited number. As described above, the number of inserted medals decreases by operating the bet switch 134. Normally, the maximum number of medals that can be inserted is 50.

S13: The sum of bets and credits is obtained.
The number of bets acquired in S1 and the number of inserted medals acquired in S2 are summed. Usually, the upper limit is 3 sheets + 50 sheets = 53 sheets.

S14: It is determined whether the total result exceeds the upper limit.

S15: The blocker is activated.
When the upper limit is exceeded (YES in S14), the blocker 1b is operated. Thereby, even if a new medal is inserted, the medal does not reach the medal sensor 1a.

S16: Start the timer TM.
The timer TM measures time from when it is activated. The output of the timer TM includes information on the time that has elapsed since it was started.

S17: It is determined whether a predetermined time has elapsed since the start of the timer TM.
Read the output of the timer TM and grasp the elapsed time. When a predetermined time has elapsed, the execution of the fraud determination process in FIG. 5 is terminated. This is to prevent the process of S18 from being repeated forever. It can be said that S17 is a timeout process. Note that the processing of S17 may not be performed.

S18: It is determined whether or not the medal sensor 1a is detected.
Since the blocker 1b is operated in S15, the output of the medal sensor 1a should not occur after that, but in rare cases, depending on the operation timing of the blocker 1b, a medal passing therethrough remains as it is in the medal path. (Swallow medals). Therefore, the process of S19 is further performed.

S19: It is determined whether the timer time is within a threshold value.
The above-mentioned swallowing of medals occurs within a few seconds after the blocker is activated, and does not occur thereafter. Therefore, when a medal is detected exceeding a predetermined threshold value (for example, 3 seconds) from the blocker operation (YES in S18 and NO in S19), it is determined as an illegal act and a predetermined error notification is performed (S21). ).

  On the other hand, if the time of the timer is within the threshold (YES in S19), it is determined that the medal is swallowed (S20), and the monitoring process of S17 to S19 is continued.

  According to the process of FIG. 5, the above-mentioned fraudulent act of obtaining fraudulent credits by inserting a device provided with two light emitting elements such as infrared LEDs at the tip and blinking them toward the medal sensor 1a. Detection and error notification can be performed. It is normally impossible to detect a medal even though the blocker 1b is activated, and it may be determined as an illegal act. According to the processing of FIG. 5, the blocker 1b is operated when the upper limit, that is, the total of 53 possible maximum bets and maximum credits is exceeded, and the main board 200 determines fraudulent activity on this condition. doing. A person who performs a fraudulent act must always be careful not to exceed the upper limit, and if the condition is exceeded, the fraudulent act is judged to be a fraudulent action and an error is reported, so that the fraudulent act becomes very difficult.

  Further, according to the process of FIG. 5, it is possible to distinguish between cheating and swallowing medals by S16 and S19. Therefore, it is possible to perform highly reliable fraud determination and error notification.

  FIG. 6 shows a flowchart of another fraud determination process according to the embodiment of the invention. The fraud determination process is executed by the main board 200, for example.

  Since FIG. 6 is similar to FIG. 5, the difference will be described below. FIG. 6 does not include processing of the timer TM.

S185: When the medal sensor 1a is detected (YES in S18), 1 is added to the number of medals (number of detections). The number of medals is different from the number of medals in the process S1 related to the medal insertion detection in FIG.
In this process, the number of detections of the medal sensor 1a occurring after the blocker 1b is activated is obtained. Although not shown in FIG. 6, simultaneously with the operation of the blocker (S15), the number of medals (number of detections) is reset (set to zero).

S19b: It is determined whether or not the number of medals is within a threshold value.
If it is within the threshold value (for example, two) (YES in S19b), this is considered to be swallowing of medals (S20), so the monitoring process of S17 to S19 is continued.

  The swallowing of the medals described above occurs in a few seconds after the blocker is activated, so it is at most one or two. Therefore, when the number of sheets exceeding the blocker operation is detected (YES in S18 and NO in S19b), it is determined as an illegal act and a predetermined error notification is performed (S21).

  The process of FIG. 6 also has the same effect as the process of FIG.

Note that the cheating determination process of FIG. 5 or 6 may be enabled only during the game. This is effective for those who play while increasing credits due to fraud. If it is not in a game, no actual harm will occur unless it is settled.
In order to avoid this, the device for cheating must be removed once the game is started. Since the act of repeatedly mounting and removing the device for fraud is conspicuous, the use of the fraudulent device is suppressed.

  For example, as shown in FIG. 7, the fraud determination process is activated (started) immediately after the process S3 related to pressing the start switch (immediately after the start switch 134 is pressed), and the fraud determination process is performed after the payout process S6 is completed. May be invalidated (stopped).

Further, when a medal is detected during the medal settlement, it may be determined as an illegal act. This is effective for an illegal act (an illegal act in which a game is not performed) in which payment is made after increasing credits by an illegal act.
Similar to the above, it is necessary to remove the fraudulent instrument during checkout. Since the act of repeatedly mounting and removing the device for fraud is conspicuous, the use of the fraudulent device is suppressed.

  FIG. 8 shows a process flowchart for determining fraudulent behavior triggered by pressing of the settlement switch 138.

S21: It is determined whether the settlement switch has been pressed.
When the settlement switch is pressed, the processing from S22 is executed.

S22: The medal is paid out.
This process is the same for conventional gaming machines.

S23: It is determined whether or not a medal sensor is detected.
While the medal is being paid out, the output of the medal sensor 1a is monitored, and when the output is generated (YES in S23), it is determined that the act is illegal, and an error is notified (S24).

S25: It is determined whether or not the medal payout has been completed.
If the output of the medal sensor 1a is not generated, the medal payout is continued until the completion (NO in S25, S22) as in the conventional gaming machine. When the medal payout is completed (YES in S25), the process in FIG.
In addition, you may make it carry out combining what is performed during a game and what is performed during checkout.

  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.
