Embodiment

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic front view of a pachinko machine 10 to which the present invention is applied. The pachinko machine 10 is provided with a main frame 11 and a window frame (not shown) including a transparent window made of glass or the like on the front surface of the main frame 11 so that the player can visually recognize the game board 12. In addition, the game board 12 is protected from the outside. An operation handle 13 is attached to the lower side of the game board 12, and when the player puts his hand on the operation handle 13 and rotates it to the right, the launching device is operated, and the game balls stored in the tray 14 are It is guided to the launching device and fired one by one. A guide rail 15 for guiding the launched game ball to the game board 12 is planted on the game board 12, and an area defined by the guide rail 15 constitutes a game area 16. On the game board 12, a plurality of game nails are planted over substantially the entire surface of the game area 16, and the game balls launched into the game area 16 flow down each time they repeatedly collide with these game nails. Change the route. Thereby, the player can enjoy various ways of flowing down the game balls. In FIG. 1, only the game nails 51, 52, and 53 are shown, but many game nails other than these are planted on the game board 12. In addition to the game nails, a windmill 21 is provided on the game board 12 as an obstacle that changes the flow path of the game balls. In addition, the pachinko machine 10 is provided with a speaker 23 to output music and sound effects for enhancing the effect of the game.

  Below the game area 16 are provided start winning ports 17 and 18, and when a game ball enters the start winning port 17, a predetermined number of winning balls are paid out from the pachinko machine 10 and the central bonus device 19. The opening / closing blade 20 performs one opening / closing operation. When the game ball enters the start winning opening 18, the opening blade 20 performs the opening / closing operation twice. The game ball can enter the central accessory device 19 only while the opening / closing blade 20 is open. For example, a movable accessory 22 is provided inside the central accessory device 19, and a game ball that has entered the central accessory device 19 is routed to a specific winning opening called a so-called V zone, or on the left and right of the specific winning opening. The route is distributed to one of the routes that lead to the regular winning opening. When the game ball enters the specific winning opening, a so-called jackpot state is reached, and the jackpot game is started. During the jackpot game, the opening / closing blade 20 repeats the opening / closing operation under a predetermined condition, so that a large number of game balls can enter the central accessory device 19. As a result, the player can acquire a large number of predetermined prize balls.

  In a normal game state other than the jackpot game state, the player aims to enter the start winning holes 17 and 18. The probability of entering the start winning holes 17 and 18 is largely affected by the installation position and angle of the game nail 51 located in the vicinity of the start winning openings 17 and 18, and therefore the possibility of reaching a big hit game, that is, a game. The number of prize balls that a player can acquire varies greatly depending on the state of the game nail 51 installed. Therefore, the game nail located in the vicinity of the start winning opening is an extremely important part responsible for the adjustment of the ball, and is therefore also the most easily targeted part of fraud. In other words, the cheating person can easily enter the game balls at the start winning ports 17 and 18 by changing the planting angle of the game nail 51 located near the start winning ports 17 and 18 from the outside. Operate like this.

  Therefore, in the gaming apparatus of the present invention, in order to prevent such an illegal act, the planting angle of the game nail 51 located in the vicinity of the start winning ports 17 and 18 is mechanically adjusted in accordance with the operation input and adjusted. When there is a displacement of a predetermined size or more from the initial planting angle of the game nail 51, this is detected and an alarm is issued.

  The details will be described below with reference to FIGS. FIG. 2 is a side view of the adjusting means of the game nail 51 located in the vicinity of the opening of the start winning opening 17 or 18 that opens upward. As shown in the figure, the game nail 51 is connected to a sphere 61, and only the game nail 51 protrudes toward the surface of the game board 12, and the sphere 61 is connected to the rotation rollers 74 and 84 of the drive units 70 and 80 inside the game board. It is supported by a ball bearing 64. FIG. 3 is a rear view of the adjusting means, that is, a view of the adjusting means viewed from the back side of the game board 12. The driving unit 70 includes a rotating roller 74, a rotating shaft unit 75, and a stepping motor 76. The rotating roller 74 is driven to rotate when the driving force generated by the stepping motor 76 is transmitted through the rotating shaft unit 75. It has become. The drive unit 80 has the same configuration as this, and includes a rotation roller 84, a rotation shaft unit 85, and a stepping motor 86. The rotation shaft 85 of the drive unit 80 is disposed in a direction orthogonal to the rotation shaft 75 of the drive unit 70, and is provided so that the rotation rollers 74 and 84 abut against the outer surface of the sphere 61 as shown in FIG. . That is, the drive units 70 and 80 support the sphere 61 inside the game board and rotate the sphere 61 in the X direction or the Y direction in the non-axial state by the driving force of the stepping motors 76 and 86. The game nail 51 connected to the sphere 61 with such a configuration is the vertical direction seen from the player corresponding to the rotation of the sphere 61 in the Y direction, and from the player corresponding to the rotation of the sphere 61 in the X direction. The planting angle can be changed in the horizontal direction when viewed. That is, the game nail 51 can be freely changed in its protruding direction by the adjusting means described above.

  FIG. 4 is a functional block diagram showing the configuration of the gaming machine of the present invention including the drive units 70 and 80 described above.

  The control unit 100 is a part that controls the main control of the gaming machine of the present invention, and includes a ROM that stores a control program, a CPU that processes the control program, a RAM that temporarily stores processing items in the CPU, and the like. The

  The operation input unit 200 is an operation input means for setting and inputting the planting angle of the game nail 51, and is configured by, for example, a numeric keypad for inputting a desired planting angle. That is, the game nail 51 is positioned in the designated state by designating the planting angles of the game nail 51 in the X direction and the Y direction from the operation input unit 200. Such operation input of the game nail 51 can be performed only when the state of the pachinko machine 10 is in the game nail adjustment mode. In the normal mode that is not the game nail adjustment mode, the operation input unit 200 performs the operation input. It is not accepted. The game nail adjustment mode is an operation mode of the pachinko machine 10 when the game nail 51 is initially set, and a game nail adjustment switch (not shown) on the control board provided on the back side of the game board 12 is operated. When the power switch (not shown) is turned on in the on state, the pachinko machine 10 is activated in the game nail adjustment mode. Further, when the game nail adjustment switch is turned off, the game nail adjustment mode is ended, the mode is changed to the normal mode, and the game becomes possible. In other words, during a game that is not in the game nail adjustment mode, the game nail 51 cannot be adjusted by the above-described operation input, and the game nail 51 is adjusted by the administrator of the game machine. One cannot do this. That is, since the player cannot operate the game nail adjustment switch and the power switch provided on the back side of the game board 12, the pachinko machine 10 cannot be switched to the game nail adjustment mode. .

  The control unit 100 supplies a control signal indicating that the state of the pachinko machine 10 is the game nail adjustment mode or the normal mode to the operation input unit 200. The operation input unit 200 accepts an operation input only when a control signal indicating the game nail adjustment mode is supplied from the control unit 100.

  The drive pulse generator 210 is configured to operate the stepping motor 76 of the drive units 70 and 80 based on the operation input from the operation input unit 200 and the position data indicating the planting angle of the game nail 51 supplied from the position detector 63 described later. A drive pulse for driving each of 86 is generated and supplied to the drive units 70 and 80. The stepping motors 76 and 86 are controlled in the driving direction and driving amount by the driving pulse, and rotate the rotating rollers 74 and 84 via the rotating shaft portions 75 and 85. Thereby, the sphere 61 rotates in the X direction and the Y direction, and the game nail 51 is positioned so as to form the planting angle designated by the operation input means 200. In addition, since the planting angle of the game nail 51 is not set to a state of being greatly displaced from a position (neutral position) orthogonal to the game board 12 in both the X direction and the Y direction, respectively. The movable range may be limited to, for example, about ± 5 degrees from the neutral position, and operation inputs exceeding this range may not be accepted. Further, the operation input of the planting angle is not limited to the method of directly inputting the desired planting angle described above, for example, by pressing the cross cursor key for operating the protruding direction of the game nail 51 for a time corresponding to the amount of displacement. It is good also as adjusting.

  In addition, the gaming device of the present invention includes angle detection means for detecting the planting angle of the game nail 51. The details will be described below. FIG. 5 is a top view of the sphere 61. A fine recognition mark 62 is provided on the upper surface of the sphere 61. The recognition mark 62 is provided so as to be generally positioned on a vertical line passing through the center point of the sphere 62 when the game nail 51 is in the neutral position. Further, as shown in FIG. 2, a position detector 63 is fixed on the surface facing the recognition mark 62. The position detector 63 includes a CCD camera having a detection surface composed of a set of pixels two-dimensionally arranged, and the projection position of the recognition mark 62 is projected by projecting an image of the recognition mark 62 onto a specific pixel. Accordingly, the two-dimensional position of the recognition mark 62 is specified, and based on this, position data indicating the planting angles of the game nail 51 in the X direction and the Y direction is output. That is, the relative position of the recognition mark 62 with respect to the position detector 63 is displaced according to the rotation of the sphere 61 in the X direction and the Y direction, that is, according to the planting angle of the game nail 51. The position detector 63 specifies the position of the recognition mark according to the displacement of the planting angle of the game nail 51 by image recognition, and detects the planting angle of the game nail 51.

  Here, when the planting angle of the game nail 51 is displaced only in the X direction from the neutral position, the relative position of the recognition mark 62 with respect to the position detector 63 is not displaced, and the recognition mark 62 is placed on the position detector 63. Images are taken as if they are rotating in the field. That is, in this case, the position detector 63 cannot capture the displacement of the position of the recognition mark 62 in spite of the displacement in the X direction. Therefore, the recognition mark 62 has a wedge shape so that the rotation angle can be specified according to the rotation in the X direction as shown in FIG. The position detector 63 recognizes the orientation of the recognition mark 62 from the captured shape of the recognition mark 62 and can detect the rotation angle of the sphere 62 in the X direction also by this. That is, the position detector 63 outputs position data indicating the planting angle of the game nail 51 from the position and orientation of the recognition mark 62.

  Furthermore, the gaming device of the present invention stores the planting angle of the game nail 51 that is initially set in the game nail adjustment mode, and when the displacement occurs from the stored planting angle, detection means for detecting this, And a notifying means for notifying when a displacement exceeding a predetermined amount is detected by the detecting means. The details will be described below with reference to FIG. After initial setting of the planting angle of the game nail 51 by the operation input unit 200, the position detector 63 detects the position and orientation of the recognition mark 62 provided on the sphere 61 by image recognition, and based on this. Position data indicating the planting angle of the game nail 51 is output and stored in the memory 90 as storage means as initial position data. Then, when the state of the pachinko machine 10 shifts to the normal mode, monitoring of the game nail 51 is started, and the position detector 63 installs the game nail 51 every predetermined period according to the control signal supplied from the control unit 100. The angle is detected and new position data is output. The displacement amount detector 91 calculates the displacement amount in the X direction and the Y direction of the game nail 51 from the new position data and the initial position data stored in the memory 90, and the calculated displacement amount is a predetermined amount. When the threshold value is exceeded, a determination signal indicating “with displacement” is supplied to the control unit 100. The memory 90 is a rewritable storage medium such as a flash memory provided on a control board (not shown) of the pachinko machine 10, and the displacement detection unit 91 is also configured by a CPU provided on the control board. Is done.

  Based on the determination signal, the control unit 100 transmits a control signal indicating that an illegal act has occurred to the voice control device 92. The sound control device 92 is a device for controlling sound such as music and sound output from the speaker 23 provided in the pachinko machine 10. When the voice control device 92 receives a control signal indicating that there is a fraud from the control unit 100, the voice control device 92 supplies an alarm sound signal to the speaker 23. Receiving this, the speaker 23 emits an alarm sound and informs the surroundings that there is a fraud. That is, the voice control device 92 and the speaker 23 constitute a notification unit. In addition, it is good also as utilizing the light emission of the electrical decoration apparatus etc. which were provided in the pachinko machine 10 with the warning sound from a speaker as an alerting | reporting means of fraud. In addition, when a management system or the like for managing the operating state of all the gaming machines is constructed in the game hall where the pachinko machine 10 is installed, the fraud is notified to the management terminal or the like on the management system. May be. In this case, when the control unit 100 transmits a control signal indicating that there is a fraud to the management terminal, it is notified on the display monitor of the management terminal that there has been a fraudulent action together with identification information such as the number of the pachinko machine. The

  When the game nail initial setting is completed and the game nail adjustment mode is terminated, the pachinko machine 10 shifts to the normal mode. When shifting to the normal mode, the game nail 51 and the sphere 61 are fixed in a state of being positioned in the initial setting. FIG. 6 is a top view showing the structure of the fixing means for the game nail 51 and the sphere 61. The game nail 51 and the sphere 61 are fixed by a pair of linear solenoids 300 in a state where the planting angle is initially set. The linear solenoid 300 is provided on both sides of the notched end portion of the game board 12 with the sphere 61 interposed therebetween, and the contact portion 302 that is protruded by the protrusion operation of the plunger 301 pressurizes the sphere 62 from both the left and right sides, thereby To fix. The contact portion 302 has a concave shape that matches the shape of the sphere 61, secures the area of the contact portion with the sphere 61, and securely fixes the sphere 61 and the game nail 51. Thereby, the planting angle of the game nail 51 is fixed to the set angle, and the planting angle does not change even if a game ball collides with the game nail 51 during the game. When the control unit 100 supplies a control signal indicating the normal mode or the game nail adjustment mode to the solenoid drive circuit 310 (see FIG. 4), the solenoid drive circuit 310 generates a drive pulse based on the control signal, and the normal mode As described above, the plunger 301 of the linear solenoid 300 is protruded to fix the sphere 61, and in the game nail adjustment mode, the plunger 301 is moved from the protruding position to the storage position, and the sphere 61 is released from the fixed state.

  Next, the adjustment operation of the game nail and the operation of detecting and notifying the illegal action against the game nail by the gaming apparatus of the present invention will be described with reference to the flowchart of FIG. Such a processing routine is executed at predetermined intervals in accordance with a control program held by the control unit 100.

  First, the control unit 100 determines whether or not the pachinko machine 10 is in the game nail adjustment mode (step S01). As described above, the pachinko machine 10 shifts to the game nail adjustment mode by turning on the power switch with the game nail adjustment switch (not shown) on the control board turned on. When the control unit 100 determines that the pachinko machine 10 is in the game nail adjustment mode (step S01 Yes), the control unit 100 allows the initial setting of the game nail 51 based on the operation input. That is, the control unit 100 supplies a control signal to the operation input unit 200 to make it ready for input. When the game nail adjustment mode is entered, the game nail 51 is positioned so that the planting angle of the game nail 51 is a neutral position perpendicular to the game board 12, for example. Initial setting may be performed. In this case, when the pachinko machine 10 shifts to the game nail adjustment mode, the position detector 63 detects the planting angle of the game nail 51 from the position of the recognition mark 62 and supplies the position data to the drive pulse generator 210. The drive pulse generating unit 210 generates a drive pulse so that the planting angle of the game nail 51 is in the neutral position, and supplies this to the drive units 70 and 80. Based on the received drive pulse, the drive units 70 and 80 rotate the sphere 61 in the X and Y directions to position the game nail 51 in the neutral position.

  When the administrator of the gaming machine inputs the initial setting value of the planting angle of the game nail 51 for each of the X direction and the Y direction from the operation input means 200, the drive pulse generating unit 210 sets and inputs the planting angle value. Based on the position data indicating the current planting angle of the game nail 51 supplied from the position detector 63, a drive pulse for driving the stepping motors 76 and 86 is generated, and this is sent to the drive units 70 and 80. Supply. The stepping motors 76 and 86 of the drive units 70 and 80 are driven according to the received drive pulse, and rotate the rotation rollers 74 and 84 via the rotation shaft portions 75 and 85. The rotating rollers 74 and 84 rotate the sphere 61 in the X direction and the Y direction, respectively, whereby the game nail 51 is positioned at the planting angle designated by the operation input means 200 (step S02).

  When the initial setting of the game nail 51 is completed and the game nail adjustment switch is turned off by an administrator or the like, the pachinko machine 10 ends the game nail adjustment mode and shifts to the normal mode. When the control unit 100 detects that the pachinko machine 10 has shifted to the normal mode (Yes in step S03), the control unit 100 supplies a control signal indicating that the pachinko machine 10 is in the normal mode to the solenoid drive circuit 310. Upon receiving this, the solenoid drive circuit 310 generates a drive signal to drive the plunger 301 of the linear solenoid 300 to the protruding position, and supplies this to the linear solenoid 300. Receiving this, the linear solenoid 300 moves the plunger 301 to the protruding position, and the contact portion 302 connected to the plunger 301 pressurizes the sphere 61 from the left and right directions and fixes the game nail 51 (step S04). That is, the game nail 51 is fixed so that the planting angle does not change even if the game ball collides during the game.

  When the fixing of the game nail 51 is completed, the control unit 100 supplies the position detector 63 with a control signal for starting the position detection of the game nail 51. The position detector 63 detects the projection position and orientation of the recognition mark 62 provided on the sphere 61 by image recognition, and outputs position data indicating the planting angle of the game nail 51 based on this. That is, the position detector 63 outputs position data indicating the planting angle of the game nail 51 that is initially set in step S02, and stores this in the memory 90 as initial position data (step S05).

  When the process of step S05 is completed, monitoring of fraud against the game nail 51 is started. The position detector 63 again detects the position and orientation of the recognition mark 62 in accordance with the control signal supplied from the control unit 100, and outputs new position data indicating the planting angle of the game nail 51. Then, the displacement amount detector 91 calculates the displacement amount of the planting angle of the game nail 51 from the new position data and the initial position data stored in the memory 90, and this displacement amount is equal to or greater than a predetermined threshold value. Is determined (step S06). The reason why the predetermined threshold value is set for the displacement amount is to exclude a small displacement that does not cause a problem, and to prevent over-detection due to errors that occur in the operation of the device and the accuracy of position measurement. It is to do.

  Further, the determination performed in step S06 is repeatedly performed a predetermined number of times to prevent erroneous determination. That is, when it is determined in step S06 that a displacement has occurred in the planting angle of the game nail 51 (Yes in step S06), the displacement amount detection unit 91 supplies a determination signal indicating “with displacement” to the control unit 100. The control unit 100 increments the value of the internal register M (initial value 0) indicating the number of determinations of “with displacement” by one (step S07). Subsequently, the control unit 100 determines whether or not the number of determinations has reached a predetermined number N (step S08). When the number of determinations is less than the predetermined number N (No in step S08), the processes from step S06 to step S08 are repeatedly executed until the predetermined number is reached.

  In the process of step S06, when the displacement amount detection unit 91 determines that the displacement amount of the game nail 51 is equal to or less than the predetermined threshold (No in step S06), the control unit 100 outputs a determination signal indicating “no displacement”. To supply. The control part 100 will complete | finish this routine, if this is received.

  On the other hand, in all the determination processes over the predetermined number of times N, when it is determined that the displacement of the game nail 51 is displaced by a predetermined value or more (Yes in step S08), the control unit 100 determines that the illegal It is determined that an action has occurred, and a control signal indicating that there has been an illegal action is supplied to the voice control device 92. The voice control device 92 supplies an alarm sound signal to the speaker 23. The speaker 23 interrupts the reproduction of music and sound effects for production based on the alarm sound signal, emits an alarm sound, and informs the surroundings that there has been an act of illegally operating the game nail in the pachinko machine 10 (Step S09).

  On the other hand, during the game, since the state of the pachinko machine 10 is in the normal mode, when this routine is executed again, it is determined in step S01 that it is not in the game nail adjustment mode (No in step S01), and from the processing of step S06. Will be executed. In this case, the initial position data stored in step S05 of the previous processing routine is held, and the stored initial position data and the new position data acquired in step S06 of the newly executed processing routine are stored. The presence / absence of displacement of the game nail 51 with respect to the position data is determined. Such processing is repeatedly executed at predetermined intervals during operation of the pachinko machine 10 according to a control program held by the control unit 100, and fluctuations in the planting angle of the game nail 51 are constantly monitored.

  In the above-described embodiment, the initial setting of the game nail 51 is automatically adjusted by an input operation from the operation input unit 200, but may be manually performed. That is, in this case, when the pachinko machine 10 shifts to the game nail adjustment mode, the setting angle of the game nail 51 is manually set using a predetermined instrument or the like in step S02. After the manual setting is completed, when the pachinko machine 10 shifts to the normal mode, the game nail 51 is fixed by the plunger 300, the position data at that position is stored, and monitoring of the displacement of the protruding position is started.

  As is apparent from the above description, according to the gaming apparatus of the present invention, the gaming nail provided in the vicinity of the winning opening is positioned at a desired planting angle based on the operation of the operation input unit. In the adjustment of the game nail, the protruding direction of the game nail can be changed in any direction by the adjusting means described above, and the game nail can be adjusted easily and accurately.

  Furthermore, the gaming device of the present invention detects a displacement of a predetermined size or more in the initial setting angle of the game nail, detects this, and considers that an illegal act has occurred, and is provided in the gaming machine. A warning sound is emitted from the given speaker and notified to the surroundings. As a result, it is possible to surely find an illegal act aiming at a game nail, which has been difficult to detect in the past, and to expect an effect of preventing the illegal act. Further, in the present invention, only the game nail 51 provided in the vicinity of the winning opening is targeted for monitoring, but a sufficient effect can be expected for fraudulent acts aimed at the game nail.

  In the above-described embodiments, the game nails provided in the vicinity of the start winning opening in the pachinko machine called so-called “feathers” are targeted for monitoring. However, the present invention is not limited to this. It is possible to appropriately select a game nail to be monitored in consideration of the past situation of fraud.
