Description

  The present invention relates to a gaming machine, and relates to a gaming machine installed in a gaming store such as a pachinko gaming machine or a slot machine.

  Conventionally, various fraudulent acts have been performed on gaming machines installed in game stores. Previous fraudsters (so-called Goto) replaced the ROM in which the program for controlling the gaming machine was written with a ROM that had been rewritten with an unauthorized program, and illegally paid out balls. Since the control board is unitized so that it can be immediately discovered that the operation has been performed, the recent fraudulent person replaces the control unit in which the ROM in which the illegal program is written is installed. In addition, fraudulent actors may sometimes become aware of fraudulent behavior if the ball is illegally dispensed many times with a specific gaming machine that has been replaced with an unauthorized control unit. Is replaced with a control unit of another game machine. If this exchange work is performed during the business, it is highly likely that the game store will find it, so some of the employees of the game store will be friends, and during the closing time, the employees of the associate will replace the control unit and the machine itself. Sometimes work is done. Thus, in recent years, fraudulent acts that occur during the closing of amusement stores have frequently occurred, and various proposals have been made to monitor this fraudulent behavior.

  For example, in Patent Document 1, identification information (gaming machine ID) for identifying each gaming machine in the manufacturing process of the gaming machine is written in the control board of the gaming machine, and each gaming machine is sold in the gaming machine sales process. The management company distributes information that associates the game store that is the seller of the game machine and the gaming machine ID of the sold gaming machine to the management company, and connects the game shop and the management company through a communication line. Disclosed is a system that monitors gaming machines installed in amusement stores and can immediately grasp if the ROM on which the control board or program is written is replaced with an unauthorized one or the gaming machine is replaced without permission. Yes. Patent Document 2 discloses a system in which a gaming machine installed in a gaming store is connected to a server of a fraud management center via a network, and fraud information detected by the gaming machine is transmitted to the server.

  However, for fraud monitoring, setting up a management company (management center) with a server, building a complex network environment and managing gaming machines installed in amusement stores nationwide It was not easy for the management company to introduce the system. In Patent Document 2, a GPS (Global Positioning System) is mounted on the above gaming machine, and the server obtains fraudulent information by transmitting position information obtained by the GPS at the time of unauthorized information transmission. Although the modification which manages the game store from which information was transmitted is also shown, utilization of GPS was restricted to the said content.

  The present invention has been made based on the above-mentioned background, and in a gaming machine installed in a game store, the location information is used to detect fraud with a relatively simple configuration so that it can be easily introduced in a game store. It is an object of the present invention to provide a gaming machine that can be used.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, a gaming machine of the present invention is a gaming machine installed at a predetermined location in a gaming store,
Position information detecting means for detecting a geographical position where the gaming machine is installed;
Position information storage means for storing position information detected by the position information detection means;
The previous position information stored in the position information storage means is compared with the current position information of the gaming machine detected by the position information detection means. Position information comparison means for determining that there is an abnormality when the position information does not exist;
It is characterized by providing.

  The gaming machine according to the present invention is installed in a game store, a position information detecting means for detecting a position where the gaming machine is installed, a position information storing means for storing the position information, and a stored previous position. Position information comparing means for comparing the information with the current position information detected by the position information detecting means is provided. And if it does not match, or if the previous position information does not exist in the position information storage means, it is determined as abnormal, for example, the position change of the gaming machine unintended by the game store side, Abnormality can be detected when a unit including a control board with an illegal ROM is replaced. In this way, the position can be managed by the gaming machine itself.

  At this time, it is possible to provide a notifying means for notifying the abnormality when the position information comparing means determines that it is abnormal. In this way, for example, when the power is turned on, the current position is detected and compared with the previously stored position information. Can know early.

  In addition, for example, a person who gains a game by performing a fraudulent act called Goto-sensei or an employee who works with Goto-sensei moves an amusement machine that has been exchanged for an illegal rom to another location. If done, anomalies can be detected. In other words, when Rom with the game contents programmed (or rewriting operation) is performed by Goto, the person who is usually called “Tachiko” plays on the replaced platform and illegally pays out balls. If a large amount of money is paid out on the same table every day, it seems suspicious to the amusement store side and notices that the rogue rom has been exchanged, so a game with a control board with a rogue rom attached at night It is possible to move the machine main body or to replace an unauthorized control board with another control board. In such a case, the position information storage means in which the position information is stored is mounted on the control board, and the position information does not match and an abnormality can be detected.

  Further, when the control unit including the control board having an illegal ROM mounted is replaced, the previous position information does not exist in the position information storage means at the next activation, and an abnormality can be detected and notified. In this way, the gaming machine itself detects an abnormality and notifies it, and it is relatively easy to prepare an expensive management system (including a server) or construct a complicated network environment. A fraud detection function can be provided in the configuration, and a gaming machine that can be easily introduced in a gaming store can be provided.

  At that time, as the notification means, a lamp that lights or blinks for a predetermined time from when the position information comparison means determines that there is an abnormality can be provided. When an abnormality is detected in this way, the lamp is lit to warn and the lamp continues to illuminate for a predetermined time, so that an employee of the amusement shop can know the abnormality without overlooking it.

In order to solve the above problems, a second aspect of the gaming machine of the present invention is a gaming machine installed at a predetermined place in a gaming store,
Integrated into a game control unit including a control program that controls the progress of the game of the gaming machine and a control board that performs control related to the progress of the game, and detects the geographical position where the game control unit is installed Position information detecting means for
Position information storage means for storing position information detected by the position information detection means;
The previous position information stored in the position information storage means is compared with the current position information of the game control unit detected by the position information detection means. Position information comparison means for determining that there is an abnormality when the position information does not exist;
It is characterized by providing.

  Thus installed in a game store and integrated into a game control unit that includes a control program that controls the progress of the game of the game machine and a control board that performs control related to the progress of the game, the game control unit is installed Position information detecting means for detecting the geographical position being stored, position information storing means for storing the position information, the stored previous position information, and the current position information detected by the position information detecting means, Position information comparing means for comparing the two. Then, if it does not match, or if the previous position information does not exist in the position information storage means, it is determined that there is an abnormality, for example, the case of the gaming machine does not move, and the control equipped with an illegal ROM Even when only the game control unit including the board is exchanged or moved, an abnormality can be detected.

(Example)
Hereinafter, an embodiment of the gaming machine of the present invention will be described with reference to an example of a pachinko gaming machine installed at a predetermined place in a gaming store. FIG. 1 is a schematic front view of a pachinko gaming machine 1 (also referred to as a gaming machine 1), and FIG. 2 is a rear view. The pachinko gaming machine 1 has a transparent glass door 2 attached to the underframe and a game board 3 that is disposed inside the underframe and is covered by the glass door 2. The game board 3 has a game area formed in a circular shape. Below the game board 3, a ball supply tray 4 is provided. The balls prepared in the ball supply tray 4 are launched toward the game board 3 by a ball launching mechanism including the handle 5. The ball that has reached the game board 3 falls on the surface of the game board 3.

  On the surface of the game board 3, a liquid crystal type liquid crystal display unit 6 is disposed at the center thereof. The liquid crystal display unit 6 is provided with a special symbol display unit 11 in which a symbol composed of three characters (numbers) is variably displayed, a general symbol display unit 12 and a reserved ball display unit 13. A special start variable winning opening 7 is provided below the liquid crystal display section 6, and a normal start winning opening 8 is provided on the left side of the liquid crystal display section 6. Below the special start variable winning prize opening 7, there are provided a large winning opening (attacker) 9 that is opened when the pachinko gaming machine 1 is a big hit, and an out opening 10 for collecting balls.

  The special start variable winning opening 7 is a so-called ordinary electric accessory, and movable members 14 and 14 are movably provided on both sides of the winning opening, and are configured as variable winning openings so as to open left and right during operation. . That is, it exhibits a closed first state (state indicated by a solid line in FIG. 1) during non-operation, and exhibits a second state (state indicated by a broken line in FIG. 1) during operation.

  Next, FIG. 3 is a block diagram showing a configuration of the game control device 20 of the pachinko gaming machine 1. The game control device 20 includes a main board 21, a CPU 22 mounted on the main board 21, a ROM 23, a RAM 24, an input / output circuit (I / O) 25, a display control board 26 to which an output of a control signal from the CPU 22 is connected, The sound control board 27, the lamp control board 28, the payout control board 29, the launch control board 30, and a power supply circuit 31 that supplies power to the game control device 20 are configured. The pachinko gaming machine 1 is controlled by a control program 51 that controls the entire pachinko gaming machine 1 stored in the ROM 23. The main board 21 has a timer 38 that starts measurement for a predetermined time triggered by a predetermined signal from the CPU 22.

  As a detection switch that outputs a detection signal when the passage of a ball is detected, a special start variable prize detector 32, a normal figure start prize detector 33, and a big prize mouth prize detector 34 are provided with an input / output circuit (I / O) 25. Via the CPU 22. A special start variable winning port opening solenoid 35 and a large winning port opening solenoid 36 are connected to the CPU 22 via an input / output circuit (I / O) 25. The special start variable prize opening opening solenoid 35 is driven by a control signal from the CPU 22 to control the opening and closing of the movable members 14 and 14. In addition, a special winning opening opening solenoid 36 is driven by a control signal from the CPU 22 to control the opening / closing of the special winning opening 9.

  A GPS control board 47 is connected to the CPU 22 via an input / output circuit (I / O) 25. The GPS control board 47 is connected to a position detector 15 that detects a position (geographic position) where the pachinko gaming machine 1 is installed. The GPS control board 47 includes a CPU and a RAM (not shown), and a ROM 49 in which a fraud detection processing program 52 is stored. The main board 21 is mounted with an EEPROM 39 (also referred to as a flash memory), which is a nonvolatile memory capable of rewriting stored contents, and is connected to the CPU 22. In the EEPROM 39, position information 40 of the pachinko gaming machine 1 detected by the position detector 15 is stored. According to such a configuration, the GPS control board 47 is provided outside the main board 21 and is stored in the ROM 49 of the GPS control board 47 even if the control program 51 stored in the ROM 23 of the main board 21 is rewritten. The fraud detection processing program 52 can be executed, and if the EEPROM 39 is arranged on the main board 21, it is possible to detect a change in position information even when only the main board 21 is replaced.

  A control signal from the CPU 22 is input to the display control board 26, and the display of the special symbol display unit 11, the general symbol display unit 12, and the reserved ball display unit 13 of the liquid crystal display unit 6 is controlled according to the control signal. Also, the audio control board 27 creates an audio signal, the audio signal is amplified, and the audio is output from the speaker 41. A control signal from the CPU 22 is input to the lamp control board 28, and lamps 42 such as decorative lamps are controlled according to the control signal. The lamps 42 include an abnormality lamp 46 that is provided at a position on the right side of the front surface of the gaming machine 1 that does not interfere with the game and that notifies an abnormality when an injustice is detected. In addition, the payout control board 29 controls the payout device 43 for winning balls or rental balls according to the control signal. Similarly, the launch control board 30 controls the ball launching device 44.

  The position detector 15 includes a well-known geomagnetic sensor 16, a gyroscope 17, a distance sensor 18, and a GPS receiver 19 for GPS that detects the position of the pachinko gaming machine 1 based on radio waves from a satellite. Since these sensors 16, 17, 18, and 19 have errors of different properties, they are configured to be used while being complemented by a plurality of sensors.

  As shown in FIG. 2, the position detector 15 is attached to the back of the pachinko gaming machine 1 so as to be connected to the main board 21 of the game control device 20 via the GPS control board 47. A ball discharge port 48 is provided on the back surface, and is connected to a ball collection basket.

  FIG. 4 shows a display example of the liquid crystal display unit 6. The liquid crystal display unit 6 is provided with a special symbol display unit 11 at the center, a general symbol display unit 12 at the lower right side, and a reserved ball display unit 13 at the lower center. The special symbol display unit 11 displays three characters (multiple digits) such as Arabic numerals. Two symbols (“2”) such as “◯” and “■” are displayed on the common map display unit 12. The holding ball display unit 13 displays the hold every time the result of the lottery performed at the time of winning the special start variable winning opening 7 is put on hold. That is, the quantity of the pending information being stored in the reserved ball storage area of the RAM 24 is displayed. In the present embodiment, the upper limit of the number of balls to be held (the number of holds) is set to four. In the holding ball display unit 13, each time the number of holdings increases, the circular display unit displays in reverse (for example, colorless to yellow) in order from the left to the right, and when it decreases, the reverse display is canceled in order from the right. The number of holds is displayed.

  The opening of the special start variable winning opening 7 will be described. The special start variable winning opening 7 is opened when a win is made by the usual drawing. When a winning of a ball is detected by the automatic starting start detector 33 attached to the general starting start winning port 8, a winning detection signal is transmitted to the CPU 22. Whether the CPU 22 obtains a random number value (counter value) from the determination counter in accordance with the timing at which the winning detection signal from the normal start winning detector 33 is input to the CPU 22, and whether or not the random number value matches the winning random number. A lottery drawing is performed by determining whether or not.

  In the present embodiment, for example, the random number range is set to “0 to 1”, “1” is hit, and “0” is lost in the common lottery. When the random number value is a winning random number in the lottery process, the winning condition is satisfied. When the winning is achieved, the common symbol display unit 12 of the liquid crystal display unit 6 displays, for example, a state where the same symbols are aligned in two columns as “OO”, for example. Note that the usual variable display time is 30 seconds in the normal state, but is designed to be shortened to 5 seconds in the time shortened state (also referred to as the time-short state). Therefore, the usual figure stops changing more frequently in the short-time state than in the normal state. Such a variable time shortening function is generally referred to as a “short-time function”, and a state in which the short-time function is activated is referred to as a short-time state. When the probability variation state is executed, the short state may be executed together at this time.

  When winning in the regular drawing, the special start variable winning port 7 is opened for 0.2 seconds in the normal state where the probability variation state does not occur, while the special start variable winning port 7 is opened for 5 seconds in the certain variation state. The special start variable winning opening releasing solenoid 35 is driven by the control signal from the CPU 22, the movable members 14, 14 are opened, the winning rate of the balls is increased, and after the opening time has elapsed, the closed state is entered. The winning rate is lower than that.

  Next, the jackpot lottery will be described. When the special start variable winning detector 32 attached to the special start variable winning port 7 detects a ball winning, a winning detection signal is transmitted to the CPU 22. Whether the CPU 22 obtains a random number value (counter value) from the jackpot determination counter according to the timing at which the winning detection signal from the special start variable winning detector 32 is input to the CPU 22, and the random number value matches the jackpot random number? A lottery lottery is performed by determining whether or not. When the random number value is a jackpot random number in the lottery process, the jackpot condition is satisfied. The CPU 22 functions as a success / failure lottery means.

  The CPU 22 receives the result of the jackpot lottery process and determines a symbol to be derived and displayed on the special symbol display unit 11 of the liquid crystal display unit 6. A display control signal based on the determination is output from the CPU 22 to the display control board 26. A big hit occurs when the special symbol display unit 11 stops displaying a predetermined special symbol. As a jackpot game, one opening and closing of the big winning opening 9 is one round, and the opening operation of the big winning opening 9 is repeatedly executed until a predetermined round (for example, 15 rounds) is reached. The CPU 22 functions as a big hit state generating means. Depending on the type of jackpot (when a specific symbol is stopped and displayed), a probability variation state (special game state) that is advantageous to the player may occur after the jackpot ends. The CPU 22 functions as a special game state generating means.

  The jackpot lottery result is temporarily stored in the reserved ball storage area assigned to the RAM 24. The CPU 22 confirms whether or not a new symbol variation operation can be performed on the liquid crystal display unit 6, and then reads the lottery result and starts the symbol variation operation. When the symbol variation operation related to the previous jackpot lottery process is performed, the lottery data including the result of the jackpot lottery process is held in the reserved ball storage area.

  Next, a specific control procedure will be described with reference to a flowchart. The fraud detection processing program 52 stored in the ROM 49 will be described with reference to the flowchart shown in FIG. The control program 51 stored in the ROM 23 is responsible for overall control of the pachinko gaming machine 1, and after the power to the pachinko gaming machine 1 is turned on, initialization processing such as interrupt mode setting and RAM check, and initialization are performed. Since this is a well-known content for executing each game process after completion of the process (a winning detection process for the special start variable winning opening 7 or the like, a jackpot lottery process, a symbol variation process, etc.), the description is omitted.

  In FIG. 5, when the power of the pachinko gaming machine 1 is turned on (S1), it is determined whether or not position information is input by the position detector 15 (position information detecting means) (S2). Here, when position information is input from the position detector 15, a current position comparison process is performed for comparing the current position with the previous position information stored in the EEPROM 39 (position information storage means) (S3). .

  The position detector 15 identifies latitude and longitude indicating the position where the pachinko gaming machine 1 is installed as position information. This position information is input to the main board 21 via the GPS control board 47, stored in the position information storage area 40 of the EEPROM 39, and updated in a predetermined procedure. When the pachinko gaming machine 1 is newly installed at a predetermined place in the gaming store, the position information of the pachinko gaming machine 1 is stored in the EEPROM 39.

  Next, the CPU 22 reads the position information detected last time from the EEPROM 39, and compares whether or not it matches the position information of the current position detected this time (S4). For location information (latitude and longitude), a predetermined threshold is set, and within that threshold is allowed as an error (considerable), and if the difference exceeds the threshold, this pachinko machine It is determined that the gaming machine 1 has moved from a predetermined location while the power is turned off, so that it is abnormal. It should be noted that even when there is no previous position information in the EEPROM 39, it is determined to be abnormal. The CPU 22 functions as position information comparison means.

  In a game store, a place where a game machine is installed may change by purchasing and installing a new game machine or changing a place where a game machine is installed in the game shop. In this case, the game store is intentionally moving the game machine and is in a normal state, but since it is not normally moved for a while after being installed in the game store, the position detected last time If the information matches the position information of the current position detected this time, it is normal, and if it does not match, it is determined that the gaming machine has moved and is abnormal. If the position information matches in S4, the process proceeds to S7. If the position information does not match, the position information stored in the EEPROM 39 is updated (S5). As a procedure, after the CPU 22 determines whether or not there is an abnormality, the current position information is stored (updated) in the EEPROM 39.

  When it is determined that there is an abnormality, an abnormality is notified for a predetermined time, and a timer (abnormality notification timer) 38 that is provided in the main board 21 and measures the abnormality notification time is set (S6). In this embodiment, for example, 30 hours is set as the predetermined time. Then, the set timer 38 starts time measurement.

  Next, it is determined whether or not the timer 38 is zero (S7). When the timer 38 is zero (when the timer 38 is not set), the process returns, while when it is not zero (when the timer 38 is set). ), The abnormal lamp 46 (informing means) is turned on (or flashes) (S8). Based on the control signal from the CPU 22, the lamp control board 28 turns on the abnormal lamp 46. In addition, in the lighting state of this abnormal lamp 46, the game of the pachinko gaming machine 1 is in a possible state. Also, when the amusement store intentionally moves the gaming machine, the lamp will be lit, so it will be noticed if the employee cares about it, but it will be lit so that it is not noticed by general players Is desirable.

  The abnormality notification time is set to 30 hours, and even if the power supply is continuously energized, the abnormality lamp 46 continues to be lit until the next day after the occurrence of the abnormality, so that an employee of the game shop overlooks the abnormality. There are few.

  Next, it is determined whether or not the abnormality notification time set in the timer 38 has reached zero (S9), and when it has reached zero, the abnormality lamp 46 is turned off (S10).

  As described above, the position detector 15 for detecting the position where the pachinko gaming machine 1 is installed and the EEPROM 39 for storing the position information are provided. The position information stored in the EEPROM 39 and the position when the power is turned on. A comparison is made as to whether or not the position information of the current position detected by the detector 15 matches, and if it does not match, or if the previous position information does not exist in the EEPROM 39, it is determined that there is an abnormality. It is always possible to check for abnormalities. When there is an abnormality, the abnormality lamp 46 is turned on for a predetermined time to notify the user, so that the occurrence of the abnormality can be surely known at an early stage.

  Further, for example, when a control unit is replaced by a suspicious person at night, the previous position information does not exist in the EEPROM 39, so that an abnormality can be detected when the power is turned on, and an illegal action can be taken promptly. In addition, if a gaming machine has been replaced by a rogue rom at the time the gaming machine is introduced to the gaming store, a group that conducts illegal acts called Goto and gains another gaming machine in the middle of the night so that it cannot be found on the gaming store side. The position is exchanged, or an illegal control board is exchanged with a control board of another gaming machine. In such a case, the control board (control device) is equipped with the EEPROM 39 in which the position information up to that point is stored. The position information becomes inconsistent, and the abnormality can be found immediately the next day. In addition, the gaming machine itself detects anomalies and notifies them, and it is not necessary to prepare an expensive management system or to build a complicated network environment, and equipped with a fraud detection function with a relatively simple configuration. It is possible to provide a gaming machine that can be easily introduced in a game store.

  The position detector 15 detects the position where the pachinko gaming machine 1 is installed. The position detector 15 controls the progress of the game of the pachinko gaming machine 1 and the control program 51 and the progress of the game. In the case of a configuration integrated with a game control device 20 (game control unit) including various control boards that perform control related to the above, it can be said that the position where the game control unit is installed is detected. Therefore, it can be said that the position detector 15 has a function of detecting the position where the pachinko gaming machine 1 is installed or the position where the game control unit is installed. In this case, when the previous position information stored in the EEPROM 39 and the position information of the current position detected by the position detector 15 do not match, it does not match. If the previous position information does not exist in the EEPROM 39, it is determined that the game control unit has been moved, and an abnormality is detected. Thereby, for example, even when the game control unit including the control board on which the illegal ROM is mounted is replaced, an abnormality can be detected.

Further, the following modifications may be added to the present embodiment.
(1) When an abnormality is detected, an abnormality signal may be output. An external output terminal connected to the CPU 22 via an input / output circuit (I / O) 25 of the main board 21 can be provided. This abnormal signal is sent to the management computer that manages each gaming machine in the amusement store, the fact that the abnormality has occurred on the computer is displayed on the monitor, the printer prints out, and there is a history that there was further abnormality You may make it manage as.

(2) When the power is turned off within 30 hours which is the set time of the timer 38, the timer 38 interrupts the timer operation (time measurement) and resumes the time measurement when the power is turned on again. It is good to do so.
(3) When the power is turned on and the comparison of the position information is executed, even if the position information is normal, there is a remaining time of the abnormality notification timer 38 (the timer 38 is activated and the abnormality notification setting time of the timer is set). It is also possible to confirm whether or not the state has not reached 30 hours. The CPU 22 reads the remaining time of the timer 38, and if there is a remaining time of the timer 38, it may be considered that the pachinko gaming machine 1 is illegal and the abnormal lamp 46 may be turned on.

(4) The stored previous position information and the current position information are compared, and when it is determined that they do not match, the new position information is also stored in addition to the stored previous position information. Good.
(5) This embodiment uses a pachinko gaming machine as an example of a gaming machine. However, the gaming machine may be a slot machine or a sealed gaming machine in which a game medium is converted into data such as points and then invested to play the game. The present invention can be implemented in various modes by replacing and selecting requirements shown in the present specification.
