  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiments. In the drawings described below, components having the same function are denoted by the same reference numerals, and repeated description thereof may be omitted.

  FIG. 1 is a front view of a gaming machine 10 according to the present embodiment. The gaming machine 10 is a ball and ball gaming machine (also referred to as a pachinko machine), and includes a game board 11 and a handle 12 on the front surface (player side). In addition, the gaming machine 10 includes a control unit 200 (not shown) that performs processing related to the gaming machine 10 on the back surface (the side opposite to the player). On the game board 11, a number of obstacle nails 13, a start port 14 for receiving a game ball, and a feather device 100 are provided.

  Furthermore, three imaging units 15, 16, and 17 are provided on the front surface of the gaming machine 10. The game ball imaging unit 15 is arranged so that its lens faces the inside of the wing device 100, and images the movement of the game sphere in the wing device 100. The face imaging unit 16 is arranged so that the lens faces the player's face, and images a region including the player's face sitting on the front surface of the gaming machine 10. The hand imaging unit 17 is arranged so that the lens faces the player's hand (near the handle 12), and images a region including the player's hand sitting on the front surface of the gaming machine 10. That is, the imaging units 15, 16, and 17 capture a portion that can identify a player who is playing a game using the gaming machine 10. The imaging units 15, 16, and 17 are arbitrary imaging devices such as a CCD camera and a CMOS camera that can digitally process imaging results in the gaming machine 10.

  FIG. 2 is a front view of the blade device 100 according to the present embodiment. The feather device 100 has a function of distributing the game balls that have entered therein into a winning opening that provides a privilege that is advantageous to the player and an outage that does not provide the privilege. The blade device 100 includes a cleon 110 (also referred to as a sorting device) and a blade member 130.

  The blade member 130 is disposed at each of the blade inlets 120 (two locations in the present embodiment), which are game ball entry paths into the blade device 100. The blade member 130 is rotatable along a direction parallel to the surface of the game board 11 and is normally disposed at a position (the position indicated by a solid line in FIG. 2) that closes the blade inlet 120. When a predetermined condition, for example, that a game ball has entered the start port 14 is satisfied, the blade member 130 rotates to a position where the blade inlet 120 is opened (the position indicated by the one-dot chain line in FIG. 2). The blade inlet 120 is rotated to a position where it is closed. Therefore, the game ball can enter the feather apparatus 100 only for a limited period after the predetermined condition is satisfied.

  The upper surface 111 of the croon 110 has a shape that is directed upward with respect to the direction of gravity and is recessed in a bowl shape. Three crunch openings 113 (also referred to as openings) are formed on the upper surface 111, and each of the crunch openings 113 penetrates the crune 110 from the upper surface 111 to the lower surface 112. At least one of the cruise ports 113 is a winning opening that provides a privilege that is advantageous to the player as the game ball passes, and at least one is an outlet that does not provide the privilege as the game ball passes. is there. The number of the crunch ports 113 may be an arbitrary number of two or more. With such a configuration, the game ball that has entered the wing device 100 through the wing inlet 120 moves in a circular or spiral manner on the upper surface 111 of the cruel 110, and is either a hit or an exit. It is distributed to the Kroon mouth 113.

  The feather apparatus 100 includes an inlet sensor 140, an outer circumference sensor 150, an upper sensor 160, and an outlet sensor 170 described later, which are four types of sensors for detecting the position of the game ball. Each sensor 140, 150, 160, 170 is connected to a control unit 200 described later via an electrical wiring (not shown). Each sensor 140, 150, 160, 170 has a predetermined detection area, and transmits a detection signal to the control unit 200 when it is detected that a game ball has passed through the detection area. Passing of the game ball includes passing of the game ball through the detection area and contact of at least a part of the game ball with the detection area.

  The inlet sensor 140 is provided in the vicinity of each blade inlet 120. The entrance sensor 140 is a reflective infrared sensor that detects an object (game ball) by irradiating infrared rays in a predetermined direction and detecting reflected light. The inlet sensor 140 detects a game ball that passes through the feather article inlet 120 and transmits a detection signal to the control unit 200. Thereby, the control unit 200 can detect the number of game balls entering the feather device 100 based on the detection result of the game balls by the entrance sensor 140. The outer circumference sensor 150, the upper sensor 160, and the outlet sensor 170 will be described later with reference to FIGS.

  FIG. 3A is a top view of the croon 110. FIG. 3B is a cross-sectional view of the croon 110 cut along the line AA in FIG. Eight outer circumference sensors 150 are provided at equal intervals on the outer circumference of the croon 110. The outer circumference sensor 150 is a reflective infrared sensor. More specifically, the outer circumference sensor 150, which is a reflective infrared sensor, includes an irradiation unit that emits infrared rays toward an object, and a light receiving unit that receives the infrared rays reflected by the object. The outer circumference sensor 150 detects the passage of an object in front of the outer circumference sensor 150 based on the time when the irradiation unit emits infrared rays, the time when the light receiving portion receives infrared rays, and the speed of light. Calculate the distance to the object. The calculation of the distance may be performed by the control unit 200 instead of the outer circumference sensor 150. In that case, the outer periphery sensor 150 transmits to the control unit 200 a signal indicating that the irradiating unit has emitted infrared light and a light receiving unit indicating that the infrared light has been received, and the control unit 200 receives the signal at the reception time of the signal. Based on this, the distance between the outer circumference sensor 150 and the object may be calculated.

  The number of outer peripheral sensors 150 is not limited to eight, and may be any number as long as it is possible to detect a game ball on the croon 110. The outer circumference sensor 150 does not need to be provided on the croon 110, and may be provided away from the croon 110 as long as the position of the game ball on the croon 110 can be detected.

  The outer circumference sensor 150 is arranged along the outer circumference of the crune 110 so as to face the center of the croon 110, and each outer circumference sensor 150 is adjusted so as to detect a game ball passing therearound. The outer circumference sensor 150 detects the game ball at the same time based on the time difference between the irradiation light irradiated on the game ball for detection and the reflected light reflected by the game ball. The distance from the outer circumference sensor 150 to the game ball is calculated. The outer circumference sensor 150 transmits a detection signal including the distance to the control unit 200. Therefore, the control unit 200 can calculate the position and speed of the game ball on the upper surface 111 of the croon 110 for each time based on the detection result of the game ball by the outer circumference sensor 150.

  FIG. 4 is a side view of the croon 110. The upper sensor 160 is provided on the inner wall of the blade apparatus 100 above the cruiser 110. The upper sensor 160 includes a light emitting unit and a light receiving unit that face each other, and is a transmissive infrared sensor that detects an object (game ball) based on a detection amount of infrared light emitted from the light emitting unit toward the light receiving unit. The number of the upper sensors 160 may be an arbitrary number as long as it is possible to detect a game ball that is separated from the croon 110.

  The upper sensor 160 is adjusted so as not to detect a game ball in contact with the upper surface 111 of the crone 110 but to detect a game ball separated from the upper surface 111 of the crone 110 above the crone 110. When detecting the game ball, the upper sensor 160 transmits a detection signal to the control unit 200. Therefore, the control unit 200 can determine that the game ball has moved upward from the upper surface 111 of the clune 110 based on the detection result of the game ball by the upper sensor 160.

  The outlet sensor 170 is provided on the inner wall of each of the cruise outlets 113 on the lower surface 112 side of the crew 110. The exit sensor 170 is a reflective infrared sensor. The outlet sensor 170 is adjusted so as to detect a game ball passing through the crone port 113. When the exit sensor 170 detects a game ball, the exit sensor 170 transmits a detection signal to the control unit 200. Therefore, the control unit 200 can detect the number of game balls coming out of the feather device 100 based on the detection result of the game balls by the exit sensor 170.

  As the entrance sensor 140, the outer circumference sensor 150, the upper sensor 160, and the exit sensor 170, in addition to the reflection type or transmission type infrared sensor, any detection member capable of detecting a game ball such as a magnetic sensor or a capacitance type sensor is used. May be used.

  FIG. 5 is a block diagram of the control unit 200 of the gaming machine 10 according to the present embodiment. In FIG. 5, the main traveling direction of the signal is indicated by an arrow, but other signals may be exchanged. The control unit 200 includes a main control board 210, a sub control board 220, and a storage device 230. The controller 200 may include an arbitrary substrate, member, etc. other than those shown here. Electric power is supplied to each board and member from a power supply board (not shown).

  The main control board 210 includes a main CPU 211, a main ROM 212, and a main RAM 213. The main control board 210 is mainly used for other than the effects of the gaming machine 10 such as detection of the operation of the handle, detection of the passing of the game ball to the start port and the winning port, the operation of the blade member and the electric accessory, and the payout of the prize ball. The control which concerns on is performed. Data such as a program for controlling each member is recorded in the main ROM 212 in advance.

  Specifically, the main CPU 211 receives a signal indicating the operation of the steering wheel, a signal indicating the passing of the game ball to the start port or the winning port, and the like, and records the signal as temporary data in the main RAM 213. The main CPU 211 reads the program and data recorded in the main ROM 212, and executes processes such as lottery, determination, and calculation using temporary data on the main RAM 213. The main CPU 211 transmits a control signal to the blade member, the electric accessory, the payout unit, etc. according to the result of the processing, and performs the operation of the blade member and the electric accessory and pays out a prize ball from the payout unit. Further, the main CPU 211 transmits a signal indicating a gaming situation such as a lottery result to the sub control board 220.

  The sub control board 220 is connected to the main control board 210 and includes a sub CPU 221, a sub ROM 222, and a sub RAM 223. The sub-control board 220 mainly performs control related to the effects of the gaming machine 10 such as lighting of lamps and reproduction of sound from the speaker in accordance with the game situation received from the main control board 210. The sub-control board 220 is connected with an inlet sensor 140, an outer circumference sensor 150, an upper sensor 160, and an outlet sensor 170, from which signals including detection results are input. Further, the game ball imaging unit 15, the face imaging unit 16, and the hand imaging unit 17 are connected to the sub-control board 220, and signals including imaging results are input thereto. The imaging results obtained by the imaging units 15, 16, and 17 are stored in the storage device 230 of the control unit 200 as image data. In the sub ROM 222, data such as a program for controlling each member is recorded in advance.

  Specifically, the sub CPU 221 receives a signal indicating a game situation from the main control board 210, a signal including a detection result from each of the sensors 140, 150, 160, 170, and the like as temporary data in the sub RAM 223. Record. Then, the sub CPU 221 reads a program (for example, a program shown in FIGS. 8 and 9 to be described later) and data recorded in the sub ROM 222, and performs processing such as lottery, determination, and calculation using temporary data on the sub RAM 223. Execute. The sub CPU 221 performs various effects and a fraud detection process described later according to the result of the process. In parallel with this, the sub CPU 221 stores the imaging results of the imaging units 15, 16, and 17 as image data in the storage device 230.

  The storage device 230 for storing the imaging results of the imaging units 15, 16, and 17 may be provided outside the gaming machine 10 instead of inside the gaming machine 10. In that case, the storage device 230 is electrically connected to the sub-control board 220 via the external connection terminal of the gaming machine 10.

  The main control board 210 and the sub control board 220 are not limited to the above-described configuration, and further include, for example, a flash memory that can read and write programs and data, a storage device such as a hard disk drive, and an arbitrary member such as a random number generator. Good. Further, the main control board 210 and the sub control board 220 may be mounted on a single board, and in that case, the CPU, ROM and RAM may be shared.

  FIG. 6 is a schematic diagram showing the movement of the game ball with respect to the upper surface of the croon 110. FIG. 7 is a schematic diagram showing the movement of the game ball with respect to the cross section of the croon 110. FIG. 7 shows a cross section of the croon 110 taken along line BB in FIG. When the game ball C enters the blade device 100 through the blade inlet 120, the game ball C falls on the upper surface 111 of the croon 110. The game ball C moves in one direction clockwise or counterclockwise as viewed on the upper surface 111 from above. The game ball C gradually moves in the direction of the center of the upper surface 111 that is recessed like a bowl while naturally decelerating due to the frictional force received from the upper surface 111, and enters one of the three cruise ports 113.

  The force received by the game ball C on the clune 110 is mainly the gravity acting on the game ball C and the frictional force generated between the game ball C and the upper surface 111, and does not change during a game in a normal environment. However, when the gaming machine 10 or the game ball C has an artificial intervention, that is, an illegal act, the force received by the game ball C changes, and the speed and movement of the game ball C change.

  For example, there is an illegal act of controlling the movement of the game ball C by magnetic force by bringing a magnet close to the game ball C that is a magnetic body from the outside of the gaming machine 10. If the game ball C is moved as desired using the magnetic force, the game ball C may be artificially put into the crone port 113 which is a hit.

  For example, there is an illegal act of controlling the movement of the game ball C through the thread by attaching a thread to the game ball C. If the game ball C is moved as desired through the thread, there is a risk that the game ball C may be artificially put into the crone port 113 which is a hit.

  For example, there is an illegal act of controlling the movement of the game ball C by vibrating the game machine 10 or the like. By changing the movement of the game ball C by vibrating the gaming machine 10, there is a possibility that the game ball C may be artificially selected as to whether the game ball C enters the exit port or the exit port 113.

  For example, there is an illegal act of changing the friction coefficient of the game ball C by attaching a substance such as oil to the surface of the game ball C. The gaming machine 10 is designed so as to obtain a hit with a predetermined probability (specifically, the game ball C enters the clue port 113 which is a hit port). However, if the coefficient of friction of the game ball C is changed from the value used at the time of design, the game ball C moves differently from the design, and the probability of winning may be artificially increased.

  The fraud determination method according to this embodiment will be described below. In the gaming machine 10 according to the present embodiment, the sub-control board 220 and the sensors 140, 150, 160, 170 cooperate to function as a fraud determination unit.

  As shown in FIG. 6, eight outer periphery sensors 150 are provided on the outer periphery of the cruel 110 at equal intervals (that is, an angle F = 45 degrees between adjacent outer periphery sensors 150). Each outer circumference sensor 150 has a detection area 151 that detects the passage of the game ball C toward the center of the croon 110. The detection areas 151 of the eight outer circumference sensors 150 are arranged so as not to overlap each other.

  When the game ball C moves on the upper surface 111 of the croon 110 in a certain direction, the game ball C sequentially passes through the detection areas 151 of the plurality of outer circumference sensors 150 along the direction. As a result, the plurality of outer circumference sensors 150 detect the game balls C in order along the direction. In other words, when the game ball C moves clockwise as viewed from above the upper surface 111, the eight outer circumference sensors 150 detect the game balls C in the clockwise order. On the other hand, when the game ball C moves counterclockwise as viewed from above the upper surface 111, the eight outer circumference sensors 150 detect the game balls C in the counterclockwise order.

  The outer circumference sensor 150 detects the game ball C, and at the same time, the difference between the irradiation time of the irradiation light irradiated to the game ball C for detection and the reception time of the reflected light reflected by the game ball C To calculate the distance D to the game ball C. Then, the outer circumference sensor 150 transmits a detection signal including an identifier indicating which of the eight outer circumference sensors 150 and the distance D to the game ball C to the sub-control board 220. The calculation of the distance D may be performed by the sub control board 220 instead of the outer circumference sensor 150.

  When the sub CPU 221 of the sub control board 220 receives the detection signal from any of the outer circumference sensors 150, the identifier of the outer circumference sensor 150 (that is, which outer circumference sensor 150 has detected), the outer circumference sensor 150, and the game ball The distance D between C and the time when the detection signal is received (referred to as detection time) is recorded in the storage device 230 as a detection record. Here, the latest detection record received from the outer circumference sensor 150 by the sub CPU 221 is referred to as a current detection record (also referred to as a second detection record).

  The sub CPU 221 reads from the storage device 230 the latest detection records detected by the seven outer circumference sensors 150 other than the outer circumference sensor 150 (also referred to as a first sensor) related to the current detection record. The sub CPU 221 regards the detection record of the seven outer circumference sensors 150 having the detection time closest to the detection time of the current detection record as the previous detection record (also referred to as the first detection record). Further, the sub CPU 221 determines that the outer circumference sensor 150 (first sensor) according to the current detection record is positioned in the clockwise direction with respect to the outer circumference sensor 150 (also referred to as second sensor) according to the previous detection record. The game ball C is considered to be moving clockwise, and the outer circumference sensor 150 (first sensor) related to the current detection record is counterclockwise with respect to the outer circumference sensor 150 (second sensor) related to the previous detection record. If it is located in the direction of rotation, it is considered that the game ball C is moving counterclockwise.

  Then, the sub CPU 221 determines the speed of the game ball C (measurement) based on the position and detection time of the game ball included in the previous detection record (first detection record) and the current detection record (second detection record). Speed Vm). The position of the game ball is obtained from the distance between the outer circumference sensor 150 and the game ball C and the angle between the outer circumference sensors 150 related to detection.

  A distance between the outer circumference sensor 150 and the game ball C related to the previous detection record is a distance D1, and a distance between the outer circumference sensor 150 and the game ball C related to the current detection record is a distance D2. The distance between the outer circumference sensor 150 and the center of the cruel 110 (fixed value defined by design) is a distance E, and the angle between the two outer circumference sensors 150 according to the previous and current detection records (fixed defined by design). Value) is an angle θ. For the sake of simplicity, assuming that the game ball C moves linearly between the two outer peripheral sensors 150, the center of the croon 110, the position of the previous game ball C, and the position of the current game ball C form a triangle. A distance G between the previous position of the game ball C and the current position of the game ball C is calculated by the following equation (1) using a triangular cosine theorem.

  This distance G is the moving distance of the game ball C from the previous detection record to the current detection record. Then, the sub CPU 221 calculates the speed Vm from the moving distance and the detection times of the previous and current detection records.

  If the previous detection record does not exist or the difference in detection time between the previous detection record and the current detection record is larger than a predetermined value, the sub CPU 221 does not calculate the measurement speed Vm and does not calculate this time. Is stored in the storage device 230 as the first detection record after the game ball C enters the croon 110.

  After the game ball C enters the croon 110, the speed naturally decreases with time, mainly due to gravity and frictional force, and approaches the center of the croon 110. That is, the speed of the game ball C decreases as the game ball C moves away from the outer circumference sensor 150. Therefore, it can be said that the speed of the game ball C on the clune 110 (referred to as an assumed speed Ve) is determined almost uniquely according to the distance between the outer circumference sensor 150 and the game ball C. Therefore, the relationship between the distance and the assumed speed Ve is acquired in advance by experiment or simulation, and recorded in the sub ROM 222 of the sub control board 220. Based on the detected distance between the outer circumference sensor 150 and the game ball C, the sub CPU 221 reads the assumed speed Ve corresponding to the distance from the sub ROM 222.

  The sub CPU 221 compares the estimated speed Ve and the measured speed Vm in the distance between the detected outer circumference sensor 150 and the game ball C. If the gaming machine 10 is subjected to artificial intervention as shown in any of the above-mentioned fraudulent acts, there will often be a difference between the assumed speed Ve and the measured speed Vm. For example, when a magnetic force is applied to the game ball C or the friction coefficient of the game ball C is changed, the measurement speed Vm becomes different from the assumed speed Ve.

  If the difference between the measured speed Vm and the assumed speed Ve read from the sub ROM 222 is greater than the predetermined range for the distance between the outer circumference sensor 150 and the game ball C in the current detection record, an illegal act Is determined to have occurred. The predetermined range is set according to the specific design of the gaming machine 10, and may be set to −10% to + 10% of the assumed speed Ve, for example.

  Moreover, you may determine generation | occurrence | production of cheating based not on the value of measurement speed Vm itself but on the variation | change_quantity of measurement speed Vm. As described above, the measurement speed Vm naturally changes mainly due to gravity and frictional force, but the change in the measurement speed Vm may be abnormal due to human intervention. In this case, the sub CPU 221 monitors the measurement speed Vm, and when the amount of change or change rate of the measurement speed Vm from the detection time of the previous detection record to the detection time of the current detection record exceeds a predetermined range, What is necessary is just to determine generation | occurrence | production of cheating.

  In the present embodiment, the occurrence of cheating is determined based on the speed of the game ball C. However, other determinations may be made as long as the determination is based on the movement of the game ball C on the cruiser 110 detected by the outer circumference sensor 150. You may determine by the method of. For example, the measured speed Vm and the assumed speed Ve may be compared not with respect to the distance between the outer circumference sensor 150 and the game ball C but with respect to the elapsed time since entering the croon 110. In addition, it is not always necessary to use the velocity of the game ball C, and the transition pattern of the position of the game ball C measured by the outer circumference sensor 150 with the passage of time is obtained in advance by experiment or simulation. May be compared.

  In the invention described in Patent Document 1, it is assumed that a game ball moves in one direction from a single entrance to an exit. Since the entrance of the game ball (that is, the place where the game ball enters) and the exit of the game ball 110 are indefinite and irregularities exist in the movement of the game ball, the game ball moving on the cruise 110 is described in Patent Document 1. It is difficult to apply this invention. On the other hand, in the gaming machine 10 according to the present embodiment, a plurality of outer peripheral sensors 150 are provided around the cruel 110, and cheating is performed based on the position of the game ball recorded using each outer peripheral sensor 150 and the detection time. Determine. Therefore, the present invention can also be applied to a game ball having an irregular entrance or exit, such as a game ball entering on the croon 110. Further, since the detection result including the position and the detection time is stored in the storage device 230, it can be confirmed whether or not the detection itself has a problem afterwards, and the reliability of the detection result can be ensured.

  As shown in FIG. 7, an upper sensor 160 is provided above the cleon 110. The upper sensor 160 has a detection region 161 for detecting the passage of the game ball C so as to cover the upper surface 111 of the cruel 110. The upper sensor 160 includes a lower upper sensor 160a disposed on the lower side (side closer to the croon 110) and an upper upper sensor 160b disposed on the upper side (side far from the croon 110). Each of the lower upper sensor 160a and the upper upper sensor 160b includes a pair of light emitting units and light receiving units facing each other.

  In a normal environment, the game ball C is mainly subjected to gravity and frictional force, so that the game ball C does not move upward, that is, away from the upper surface 111 of the crone 110. However, for example, by artificially applying vibration to the gaming machine 10, the game ball C may be moved in a desired manner and illegally put into the clune port 113 that is a winning hole. In the present embodiment, after the lower upper sensor 160a detects the game ball C, when the upper upper sensor 160b detects the game ball C, it is determined that the game ball C is moving in a direction away from the croon 110. .

  Specifically, when the lower upper sensor 160a and the upper upper sensor 160b detect that the game ball C has passed through the detection area 161, the lower upper sensor 160a and the upper upper sensor 160b transmit detection signals to the sub-control board 220.

  If the sub CPU 221 of the sub control board 220 receives the detection signal from the lower upper sensor 160a and receives the detection signal from the upper upper sensor 160b within a predetermined time (for example, 1 millisecond), It is determined that an action has occurred. At the same time, the sub CPU 221 records the time when the detection signals are received from the lower upper sensor 160 a and the upper upper sensor 160 b in the storage device 230.

  As shown in FIG. 7, an outlet sensor 170 is provided on the inner wall of the crunch port 113. The exit sensor 170 has a detection region 171 for detecting the passage of the game ball C so as to cross the space in the crunch port 113.

  Under normal circumstances, the game ball C is mainly subjected to gravity and frictional force, so the game ball C that has fallen to the cruise port 113 moves upward in the cruise port 113, that is, in a direction to return to the upper surface 111 of the cruiser 110. Never do. However, for example, by attaching a thread to the game ball C and pulling the thread from the outside of the gaming machine 10, there are cases where it is possible to pass through the Kleung port 113 which is a contact hole many times. In the present embodiment, when the number of game balls C detected by the exit sensor 170 shown in FIG. 7 becomes larger than the number of game balls C detected by the entrance sensor 140 shown in FIG. judge.

  Specifically, first, the inlet sensor 140 transmits a detection signal to the sub-control board 220 when detecting that the game ball C entering the feather device 100 has passed through the detection region. When the sub CPU 221 of the sub control board 220 receives the detection signal from the inlet sensor 140, the sub CPU 221 records the time when the detection signal from the inlet sensor 140 is received in the storage device 230.

  When the exit sensor 170 detects that the game ball C has passed through the detection area 171 in the cruise port 113, the exit sensor 170 transmits a detection signal to the sub-control board 220. When the sub CPU 221 of the sub control board 220 receives the detection signal from the outlet sensor 170, the sub CPU 221 records the time when the detection signal from the outlet sensor 170 is received in the storage device 230.

  Then, the sub CPU 221 reads out and counts the detection results of the game balls C by the entrance sensor 140 and the exit sensor 170 recorded in the storage device 230 from the start of the game to a certain point in time, and the game balls C detected by the entrance sensor 140 If the number of game balls C detected by the exit sensor 170 is larger than the number of, it is determined that an illegal act has occurred.

  Since the gaming machine 10 according to the present embodiment includes a plurality of types of sensors, various types of fraud can be detected.

  The cheating determination method according to the present embodiment is not limited to the specific method described above, and various changes are made as long as cheating can be detected based on the passing record of the game ball by the sensor. Good. The cheating determination method according to the present embodiment is based on the assumption that only one game ball enters the feather device 100, but is applied when a plurality of game balls enter the feather device 100 simultaneously. It's okay. In that case, a device such as recording detection records separately for a plurality of game balls that have entered the feather apparatus 100 at the time of mounting may be appropriately performed.

  The fraud recording method according to this embodiment will be described below. When the sub CPU 221 determines the occurrence of the cheating by the above cheating determination method, the sub CPU 221 stores the imaging results by the imaging units 15, 16, and 17.

  Specifically, when a game using the gaming machine 10 is started, the gaming ball imaging unit 15 starts imaging the movement of the gaming ball in the feather device 100, and the facial imaging unit 16 is used for the gaming machine 10. The imaging of the area including the face of the player sitting on the front of the player starts, and the hand imaging unit 17 starts imaging of the area including the hand of the player sitting on the front of the gaming machine 10. The sub CPU 221 sequentially saves the imaging results of the imaging units 15, 16, and 17 in the storage device 230 as still image or moving image data (referred to as temporary storage data).

  When the sub CPU 221 determines the occurrence of the fraud by the above fraud determination method, the sub CPU 221 duplicates the portion of the temporarily stored data up to the point of the first time (for example, 10 minutes) after the occurrence of the fraud. The data is saved in the storage device 230 as saved data. The sub CPU 221 sequentially deletes a portion of the temporarily stored data that has passed a second time (for example, one hour) longer than the first time since being stored in the storage device 230. Therefore, the temporary storage data for the second time at the maximum is maintained in the storage device 230, and the temporary storage data of the portion after the second time has elapsed from the storage time is deleted from the storage device 230. On the other hand, the officially stored data is not deleted even after the second period has elapsed, and is maintained in the storage device 230 unless it is explicitly deleted by an instruction from the user or the like. In other words, when the sub CPU 221 determines the occurrence of the illegal act, the sub CPU 221 leaves the portion of the image data from the time when the illegal activity has occurred to the time point that has been traced back for the first time, and stores the other parts. To after a second time longer than the first time.

  Even if imaging is started after the occurrence of an illegal act is detected, it may not be possible to leave evidence of the important illegal act depending on the elapsed time between the detection and the start of imaging. On the other hand, in order to always save the image data of the gaming machine 10 in the storage device 230 regardless of the occurrence of fraud, the storage device 230 with a huge capacity is required, and the introduction of the gaming machine 10 is very expensive. Take it. On the other hand, according to the fraudulent act recording method according to the present embodiment, when the occurrence of the fraudulent act is determined, only the image data of the part relating to the fraudulent act is officially saved, and the temporarily saved image data Is deleted after a predetermined time. Therefore, image data for a predetermined time can be reliably left as evidence retroactively from the occurrence of fraud. That is, since a video traced back for a predetermined time including an image at the time of detection is stored on the basis of the time when the fraud is detected, the person who has just performed the fraud (hereinafter referred to as the fraudster) ) Can be left as evidence video (in this embodiment, the face of the fraudster and the suspicious movement of the game ball in the croon). At the same time, the capacity required for the storage device 230 can be reduced, and the introduction cost can be reduced.

  FIG. 8 is a view illustrating a flowchart of the fraud detection process executed in the gaming machine 10 according to the present embodiment. The fraud detection process is stored as a program in the sub ROM 222 of the sub control board 220, and when a game using the gaming machine 10 is started, the sub CPU 221 reads it out on the sub RAM 223 and executes it.

  First, the sub CPU 221 starts imaging using the imaging units 15, 16, and 17 (step S10). The sub CPU 221 sequentially stores the image data of the imaging results obtained by the imaging units 15, 16, and 17 as temporary storage data in the storage device 230, and the portion of the temporary storage data that has passed a second time (for example, 1 hour) has been stored. Delete sequentially. The process of storing and deleting temporary storage data is performed in parallel with the flowchart of FIG.

  Next, the gaming machine 10 performs a fraud determination process described later (step S100). When it is determined in the fraud determination process in step S100 that a fraud has occurred (YES in step S20), the sub CPU 221 performs a fraud recording process (step S30). Specifically, the sub CPU 221 duplicates the image data from the first time (for example, 10 minutes) before the second time to the present among the temporarily saved data, and saves it in the storage device 230 as the officially saved data. .

  Thereafter, when a predetermined end condition is satisfied, for example, when the player gives an end instruction on the mobile terminal or when the game using the gaming machine 10 is not performed for a predetermined time (YES in step S40), the gaming machine 10 End the fraud detection process. Otherwise (NO in step S20, NO in step S40), the gaming machine 10 repeats the processing from step S100 at a predetermined time interval (for example, 1 millisecond).

  FIG. 9 is a flowchart of the fraud determination process S100. First, the sub CPU 221 of the sub control board 220 checks signals from the sensors 140, 150, 160, and 170 (step S101).

  When the sub CPU 221 receives a signal indicating that a game ball has been detected from the entrance sensor 140 or the exit sensor 170 (YES in step S102), the sub CPU 221 records the time when the signal is received in the storage device 230 (step S103). .

  The sub CPU 221 reads out and counts the detection results of the game balls by the entrance sensor 140 and the exit sensor 170 recorded in the storage device 230 from the start of the game using the gaming machine 10 to the present, and adds up the entrance sensor 140 and the exit sensor 170. Calculates the number of game balls (total number of passages) respectively detected (step S104).

  When the number of game balls detected by the exit sensor 170 is larger than the number of game balls detected by the entrance sensor 140 (YES in step S105), the sub CPU 221 determines that an illegal act has occurred (step S106). .

  Next, when the sub CPU 221 receives a signal indicating that a game ball has been detected from the upper sensor 160 (that is, the lower upper sensor 160a or the upper upper sensor 160b) (YES in step S107), the sub CPU 221 receives the signal. The recorded time is recorded in the storage device 230 (step S108).

  The sub CPU 221 reads out the detection result of the gaming ball by the lower upper sensor 160a and the upper upper sensor 160b recorded in the storage device 230 from the start of the game using the gaming machine 10 to the present. When the sub CPU 221 indicates that the detection result is received from the upper upper sensor 160b within a predetermined time (for example, 1 millisecond) after the detection result is received from the lower upper sensor 160a. It is determined that the game ball is moving in the upward direction (the direction away from the clown 110), and if not, it is determined that the game ball is moving in the downward direction (step S109).

  When the sub CPU 221 determines that the game ball is moving upward (YES in step S110), the sub CPU 221 determines that an illegal act has occurred (step S106).

  Next, when the sub CPU 221 receives a signal indicating that a game ball has been detected from any of the eight outer circumference sensors 150 (YES in step S111), the sub CPU 221 identifies the identifier indicating the outer circumference sensor 150, and the outer circumference sensor. The distance from 150 to the game ball and the time when the signal is received are associated with each other and recorded in the storage device 230 (step S112).

  The sub CPU 221 is based on the detection record of the seven outer circumference sensors 150 other than the outer circumference sensor 150 that has the latest detection time (previous detection record) and the current detection record relating to the signal received in step S101. Then, the speed of the game ball (measurement speed Vm) is calculated (step S113). Further, the sub CPU 221 reads the assumed speed Ve corresponding to the distance from the outer circumference sensor 150 to the game ball in the current detection record from the sub ROM 222.

  When the difference between the measured speed Vm and the assumed speed Ve exceeds a predetermined range (for example, -10% to + 10% of the assumed speed Ve) (YES in step S114), the sub CPU 221 determines that an illegal act has occurred. Determination is made (step S106).

  At least a part of the fraud detection processing according to the present embodiment may be performed by an external server provided outside the gaming machine 10. In that case, the gaming machine 10 transmits necessary data to the external server via the external connection terminal, and the CPU of the external server performs at least a part of the above-described fraud detection processing using the data. The gaming machine 10 may receive the processing result.

  In the cheating detection process according to the present embodiment, since cheating is determined using a plurality of types of sensors 140, 150, 160, and 170, various kinds of cheating can be detected. In addition, since the position and time of the game ball stored by using the plurality of outer peripheral sensors 150 provided in the croon 110 are used, the occurrence of fraud is also determined for the game ball that moves irregularly on the croon 110. be able to. Furthermore, since the detection result including the position and the detection time is stored in the storage device 230, it can be confirmed whether or not the detection itself has a problem afterwards, and the reliability of the detection result can be ensured.

  Furthermore, in the fraud detection process according to the present embodiment, when fraud is detected, the image data of the time related to the fraud can be reliably left as evidence, and the image data of other times is stored. It can be deleted to reduce the storage capacity and reduce the introduction cost.

  In the above-described embodiment, image data is left retroactively from the time of occurrence of fraud, but the present invention is not limited to this. In one embodiment of the present invention, it is important to leave evidence of fraudulent behavior as an image when there is fraudulent behavior by a player. Therefore, when a control unit such as the control unit 200 detects an event that is regarded as a predetermined fraud, ideally, an image (for example, a face) that can identify a player at that moment, or before that moment, Then, the identifiable image is stored in at least one of the following. If the time zone before and after the above moment is short (for example, 1 to 2 seconds, etc.), it can be said that it is difficult for an unauthorized person to appear or disappear in the shooting range between this moment and around this time zone. I will. Therefore, even if the image that can be identified at the moment cannot be captured, it can be said that the image that can be identified is substantially captured if the time period is short. It should be noted that the time zone values before and after the above moment are not essential, and based on the time when a cheating player detects the act, the cheating player involved in the detection is within the shooting range. It is essential to take an image that can be identified within the existing period (or “period in which it can be assumed that it exists”). Therefore, if this can be realized, there is no problem with the time values before and after the detection.

  In addition, the main purpose of the fraud against the pachinko machine according to the present embodiment is to try to put a game ball into the clown mouth 113 which is a winning mouth in order to illegally realize the so-called V prize (winning in the V zone). Therefore, it can be said that fraudsters tend to keep track of whether or not they will win big hits after fraud. In other words, it can be said that the timing when the fraudster leaves the gaming machine that cheated is at least after the notice is over. Therefore, in the case of photographing the fraudulent person after a predetermined time from the detection of the fraud, the timing of photographing the identifiable image is fraudulent in consideration of the period during which the fraudulent person may be aware of whether or not it is a big hit. It is preferably within 10 seconds after detection (at the time of occurrence of fraud), and more preferably within 5 seconds after fraud detection.

  Thus, in one embodiment of the present invention, a control device such as the control unit 200 can identify an image (for example, a face) that can identify a player who would have executed the fraud at the time when the fraud was detected, or the It is essential that at least one of the above-identifiable images (whether a moving image or a still image) before a predetermined time and after a predetermined time is acquired and stored in the storage device. According to the storage method described in the present embodiment, the essence can be realized. However, for example, when the control unit 200 detects an illegal act as a trigger, the imaging unit (at least the imaging unit 16) uses the player's You may make it photograph a face etc. Alternatively, the control unit 200 causes the imaging unit (at least the imaging unit 16) to always shoot the imaging target, associates the captured image with the time, stores the image in the storage unit such as the sub-RAM 223, and the image at the time when the illegal act is detected. Alternatively, at least one image before and after a predetermined time before the time may be extracted from the image stored in the storage unit.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.

  A program (for example, a program that causes a game machine to execute the processing shown in FIGS. 8 and 9) for operating the configuration of the embodiment so as to realize the functions of the above-described embodiments is recorded on the recording medium, A processing method of reading a recorded program as a code and executing it in a control unit of a gaming machine which is a computer is also included in the category of each embodiment. That is, a computer-readable recording medium is also included in the scope of each embodiment.
