The present invention relates to a gaming machine provided in a gaming board.

  A pachinko machine, which is a typical gaming machine, has a frame-shaped decorative member (a so-called center accessory) disposed at a substantially central position of a gaming area defined on the surface of the gaming board. A symbol display device such as a liquid crystal type or a drum type that displays a plurality of symbols in a variable manner via the rear face, and a symbol display device by winning a pachinko ball (game ball) at a position below the decorative member in the game board Many proposals have been proposed in which a start winning device for starting symbol variation in the game and a special winning device that is opened at the time of a big hit are arranged. In such a pachinko machine, the pachinko ball launched into the game area gradually flows down due to its own weight while bouncing off by contact with a game nail or the like implanted in the game area, and starts in the process of flowing down the game area. By winning at the winning opening of the winning device, various game effects such as reach effects accompanying symbol fluctuations are made on the symbol display device, and when the symbols stop on the symbol display device in a predetermined combination, so-called big hit games or A hit game such as a small hit game is generated.

  A side of the decorative member is provided with a ball introduction port that takes in a pachinko ball that opens into the game area and flows down the game area, and a pachinko that is taken in from the ball introduction port at the lower edge of the decoration member. A stage for discharging the ball to the game area after rolling the ball is provided. In this stage, a plurality of discharge paths having different winning probabilities to the winning opening are set, including a discharging path that can be won with high probability at the winning opening of the start winning apparatus. In addition, the game board is provided with an opening / closing type winning opening that is opened and closed by an opening / closing member in the start winning device, and a ball passage gate through which a pachinko ball flowing down the game area can pass is provided. A ball detection sensor provided on the gate detects a pachinko ball so that the open / close member that closes the open / close type winning opening is opened.

  By the way, since pachinko balls used in pachinko machines are steel balls, in pachinko machines where pachinko machines are installed, pachinko balls that flow down the game area with a magnet close to the glass surface of the pachinko machine. `` Magnet that gains fraudulently by guiding directly to the winning opening of the starting prize winning device or collecting pachinko balls at a predetermined place and intentionally causing clogging of the balls and causing the pachinko balls to flow down a specific route Fraudulent acts "may occur. For this reason, for example, in the pachinko machine disclosed in Patent Document 1, a magnetic sensor is arranged on the back side of a collective bowl attached to the back side of the game board, and the magnetism of the magnet brought close to the glass surface in an attempt to cheat is detected with the magnetic sensor. Countermeasures against fraud such as stopping the ball-hitting device when detected are proposed.

Various game parts are arranged between the two-ball passage member 111) and the frame-shaped decorative body 40 so as to ensure a space that can be used.

(Operation of Example)
Next, the operation of the pachinko machine 10 according to the embodiment configured as described above will be described.

  When a player rotates the operation handle 17 provided on the front side of the middle frame 12, a game area in which pachinko balls launched from the ball striking device are defined by guide rails 21 provided on the game board 20 It is driven into 20a and flows down in the game area 20a while contacting the game nail 24 and changing the flow direction. Then, the pachinko ball flowing down the game area 20a wins the upper and lower start winning ports 31a and 31b of the start winning device 30, whereby the symbol change effect on the symbol display device 18 is started, and the symbol change effect is displayed. As a result, when a decorative figure is displayed in a predetermined symbol combination on the symbol display device 18, a big hit is generated, and the first special winning device 35 provided on the game board 20 or the The second special winning device 50 is opened, and a big hit effect is performed in the symbol display device 18.

  Here, in the pachinko machine 10 of the embodiment, in a state where the game board 20 and the installation member 95 are assembled, a part of the magnetic sensor 108 attached to the sensor installation part 107 is a ball on the back side of the game board 20. It is located inside the detection area RA connecting the introduction port 44a, the ball passage gate 47, and the second special prize port 51 of the second special prize device 50, and the ball introduction port 44a, the ball passage gate 47, and the second special prize port 51. Each of the winning openings 51 is configured to be covered by the magnetic detection range of the magnetic sensor 108. That is, a wide range of illegal acts can be detected without using the plurality of magnetic sensors 108, and the manufacturing cost of the pachinko machine 10 can be reduced. Further, a part of the magnetic sensor 108 is located inside the detection area RA connecting the ball introduction port 44a, the ball passage gate 47, and the second special winning port 51, so that the ball introduction port 44a, the ball passage It is possible to suppress the occurrence of bias in the fraud detection sensitivity using magnetism with respect to the gate 47 and the second special prize opening 51, and it becomes possible to effectively detect the fraud of each part.

  Further, since the sensor installation portion 107 is provided in the first ball passage member 101 disposed so as to face the opening front end portion of the installation member 95 at a position close to the back surface of the game board 20, the magnetic installation portion 107 is magnetic. The separation distance between the sensor 108 and the front surface of the game board 20 can be shortened. For this reason, since it is possible to effectively detect fraudulent acts due to magnetism using an inexpensive magnetic sensor 108 having a relatively low magnetic detection sensitivity, it is not necessary to employ an expensive magnetic sensor with high sensitivity, thereby reducing costs. You can plan. Further, the magnetic sensor 108 can be easily positioned and held at a predetermined position simply by inserting the magnetic sensor 108 from the insertion port 107b of the sensor installation portion 107, and the detection sensitivity varies for each pachinko machine 10. Can be prevented, and a constant detection sensitivity can be maintained. Further, since the magnetic sensor 108 is accommodated and held in the sensor installation portion 107, the magnetic sensor 108 can be protected.

  In addition, the magnetic sensor 108 is disposed on the upstream side of the normal prize opening member 90 provided on the game board 20. Therefore, a so-called “grape” is formed in which the pachinko balls are intentionally gathered and clogged between the game nails 24 on the upstream side of the normal winning opening 92a, and the pachinko balls are intentionally moved to the starting winning openings 31a and 31b and the normal winning opening 92a. The magnetic sensor 108 for detecting an illegal act using magnetism with respect to the ball introduction port 44a, the ball passing gate 47 and the second special winning port 51 even when an illegal act that makes it easy to win a pachinko ball by flowing down is performed. In addition, the number of magnetic sensors 108 can be reduced, and the cost can be further reduced.

  Here, in the second special prize-winning device 50 disposed in the frame-shaped decorative body 40, the pachinko ball that has won the second special prize-winning port 51 is placed behind the frame-shaped decorative body 40 via the rear guide passage 63a. And then a special winning ball discharge passage 80 is formed for guiding to the left side of the frame-shaped decorative body 40 through the first side guide passage 64a, the longitudinal passage 65a and the second side guide passage 78a. Yes. Accordingly, the ball-shaped decorative body 40 is provided with the ball introduction portion 44 (ball introduction port 44a), the ball guide passage 45, and the stage 46 for temporarily taking pachinko balls flowing down the game area 20a. 2 Even when the special prize-winning device 50 is arranged at the approximate center of the upper and lower sides of the left side of the frame-shaped decorative body 40 so as to be close to the upper side of the ball introduction part 44, The pachinko ball can be reliably guided to discharge. Thereby, the freedom degree of the installation position of the 2nd special prize-winning apparatus 50 with respect to the frame-shaped decorative body 40 can be raised. At this time, the first side guide passage 64a, the vertical passage 65a, and the second side guide passage 78a in the special winning ball discharge passage 80 overlap with the case body 57 or the frame-shaped decorative body 40 in the front-rear direction. , 65a and 78a are not visible from the player side, and the appearance of the pachinko machine 10 is not impaired. The special winning ball discharge passage 80 is formed so that the discharge port 79 of the second side guide passage 78a opens at the side end portion position of the frame-shaped decorative body 40. The frame-shaped decorative body 40 can be attached to and detached from the first mounting opening 22a of the game board 20 with the above installed. Further, since the first ball discharge guide passage 102 communicating with the special winning ball discharge passage 80 is provided in the installation member 95, the special winning ball discharge passage 80 formed in the frame-shaped decorative body 40 can be minimized. it can.

  The first ball discharge guide passage 102 provided in the installation member 95 guides the pachinko ball coming from the special winning ball discharge passage 80 to the painting wall portion 97b forming the left side surface of the installation member 95 by the upper inclined passage 104. Thus, it is configured to flow down along the wall portion 97b through the side passage 105 and the lower inclined passage 106. Accordingly, the first ball discharge guide passage 102 can be separated from the frame-shaped decorative body 40, and a space for installing various game parts around the left side of the frame-shaped decorative body 40 with respect to the installation member 95 can be secured. it can. Further, the second ball discharge guide passage 113 communicating with the first ball discharge guide passage 102 is formed so as to follow a route separated from the frame-shaped decorative body 40 at a position passing over the normal winning ball discharge passage 112. Thus, it is possible to secure an installation space for various game parts around the lower side of the frame-shaped decorative body 40 with respect to the installation member 95. Moreover, since each of the first sphere discharge guide passage 102 and the second sphere discharge guide passage 113 is located on the opening front end side of the installation member 95, it overlaps the rear of the first sphere discharge guide passage 102. Thus, even with the configuration in which the second special prize device 50 is arranged on the frame-shaped decorative body 40, the game effects can be diversified.

  In addition, the second special prize-winning device 50 is installed close to the side (left side) where the ball passing gate 47 is formed in the frame-shaped decorative body 40 (between the ball passing gate 47 and the bowl-shaped portion 42). The first upstream path 26a for one pachinko ball is formed on the right and left sides of the frame-shaped decorative body 40, so that the frame-shaped decorative body 40 can be prevented from being unnecessarily enlarged. Further, since each of the ball introduction port 44a, the ball passing gate 47, and the second special winning device 50 is arranged on the left side of the frame-shaped decorative body 40, it is compared with a configuration in which these are distributed. The opening area of the display window 40a of the frame-shaped decorative body 40 is not squeezed, the large symbol display device 18 can be adopted, and various game effects can be performed. Further, in the game area 20 a of the game board 20, on the upstream side of the ball passage gate 47, it passes between the ball passage gate 47 and the frame-shaped decorative body 40 toward the second special winning device 50. A first upstream path 26 a in which the sphere flows down, a second upstream path 26 b in which the pachinko sphere flows down toward the sphere passage gate 47, and a third upstream in which the pachinko sphere passes between the sphere passage gate 47 and the guide rail 21. Since the path 26c is formed, it is possible to employ the large symbol display device 18 by maximizing the display window 40a of the frame-shaped decorative body 40, and the pachinko ball flowing down the game area 20a. The movement will not be monotonous.

  In addition, a first downstream path 27a in which the pachinko ball moves toward the second special winning device 50 is formed on the downstream side of the ball passing gate 47, and the pachinko ball is directed to the second special winning device 50. Since no second downstream path 27b is formed, the movement of the pachinko sphere that has passed through the ball passage gate 47 can be changed. Further, since the pachinko balls detected by the passing ball detection sensor 48 of the ball passage gate 47 can flow down toward the second special winning device 50, the pachinko balls enter the first upstream path 26a on the upstream side of the ball passage gate 47. Even when it does not move, it can be expected that the pachinko ball will win the second special winning device 50.

  Further, the second special winning device 50 according to the embodiment includes one case each of the special winning opening opening / closing member 53, the second special winning solenoid 52, the special winning ball discharge passage 80, and the second special winning ball detection sensor 55. Since the unit member is incorporated in the body 57, the workability of assembling the frame-shaped decorative body 40 to the installation portion 49 is high. Moreover, when the second special prize device 50 including the drive part (second special prize solenoid 52 and the operation mechanisms 82 and 86) that are easily damaged when used in a game is unitized, there is a problem with the drive part. Even if it occurs, the entire second special prize-winning device 50 can be easily exchanged, and maintenance can be improved and the game can be continuously used.

  In the second special prize winning device 50, the rear guide passage 63a is exposed to the lower side of the special prize opening opening / closing member 53 when the special prize opening opening / closing member 53 is opened. That is, in the big hit that opens the second special prize-winning device 50, the special prize-mouth opening / closing member 53, which is designed to imitate the head of the dragon, opens the dragon and opens the second special prize. The pachinko ball won in the mouth 51 moves to the rear guide passage 63a located between the special prize mouth opening / closing member 53 and the design body 66 fixedly provided in the case body 57, so that it appears in the mouth of the dragon. Can look like Furthermore, since the pachinko sphere moves from the rear guide passage 63a to the first side guide passage 64a, it is possible to make an illusion that the pachinko sphere is swallowed into the oral cavity of the design imitating the head of a dragon. The entertainment of the game can be given by the movement of the pachinko ball won in the winning device 50. Further, the player can confirm the winning situation of the pachinko ball to the second special winning opening 51 only by looking at the rear guide passage 63a appearing below the special winning opening opening / closing member 53. On the other hand, in the state where the special prize opening opening / closing member 53 is in the closed position, the rear guide passage 63a is located behind the second decorative portion 53c, and the rear guide passage 63a is invisible from the front side by the second decorative portion 53c. Since it is covered, the decorativeness is not impaired.

  On the other hand, the second special prize-ball detecting sensor 55 disposed in the second special prize-winning device 50 has the special prize-winning opening when the special prize-opening opening / closing member 53 is rotationally displaced between the closed position and the open position. The opening / closing member 53 is configured to be hidden behind the second decorative portion 53c. Therefore, when the special prize opening / closing member 53 is opened / closed, the second special prize ball detection sensor 55 can be prevented from being visually recognized from the player side, and the decorativeness is not impaired. A sensor holder 61 for holding the second special winning ball detection sensor 55 is formed adjacent to (in the vicinity of) the rotation shaft 54 of the special winning opening / closing member 53, and the second special winning opening 51 is awarded. Since the pachinko balls that have been played can be quickly detected by the second special winning ball detection sensor 55, it is possible to effectively prevent the occurrence of more than a predetermined number of winnings (over winnings) in the second special winning port 51. . At this time, since the second special winning ball detection sensor 55 is covered with the second decorative portion 53c of the special winning opening / closing member 53, a blind member such as a decorative member is hidden in front of the second special winning ball detection sensor 55. There is no need to apply them separately, and the number of parts and cost can be reduced.

  The second special winning ball detection sensor 55 is adjacent to the side of the rotary shaft 54 in a posture in which the longitudinal direction of the sensor 55 is aligned with the axial direction of the rotary shaft 54 of the special prize opening opening / closing member 53. Therefore, it is not necessary to make the second decorative portion 53c excessively large in order to cover the second special winning ball detection sensor 55. For this reason, the freedom degree of the form of the 2nd decoration part 53c is high, and the design of the 2nd special prize-winning apparatus 50 can be determined suitably.

  Further, in the second special prize winning device 50, when the second special prize solenoid 52 is not driven, the operating member 86 is displaced to the lock position, and the lock portion 86a provided on the operating member 86 is engaged with the restricting protrusion 85. In addition, the displacement of the special prize opening / closing member 53 from the closed position to the open position is restricted. Accordingly, the second special prize opening 51 cannot be opened because the special prize opening opening / closing member 53 is operated to be opened directly by an unauthorized instrument or the like, regardless of the driving of the second special prize solenoid 52. Unauthorized opening of the opening / closing member 53 can be prevented. Further, in this state, since the engagement between the opening / closing operation hole 89 provided in the operation member 86 and the connecting shaft portion 84 is released, the special prize opening opening / closing member 53 is prevented from being accidentally displaced to the open position. it can.

  On the other hand, when the operating member 86 is displaced from the locked position to the unlocked position in accordance with the driving of the second special prize solenoid 52, the engagement between the restricting protrusion 85 and the locked portion 86a is released and the The opening / closing operation hole 89 and the connecting shaft portion 84 are engaged. Therefore, the special prize opening opening / closing member 53 can be opened by further displacing the operating member 86 from the unlocked position to the operating position. That is, in the second special prize device 50 according to the embodiment, an illegal opening operation of the special prize opening opening / closing member 53 that is not dependent on the driving of the second special prize solenoid 52 can be prevented. Further, the connecting member 82 fixed to the rotating shaft 54 of the special prize opening opening / closing member 53 is provided with a connecting shaft portion 84 and a restricting projection 85, and the operating member 86 provided in the second special winning solenoid 52 is opened and closed. With a simple configuration provided with a hole 89 and a lock portion 86a, the special prize opening opening / closing member 53 is switched between a locked state and a unlocked state as the second special prize solenoid 52 is driven. The entire second special winning device 50 can be made compact.

  Further, when the special prize opening / closing member 53 is rotationally displaced to the open position, the rotational force directed to the closed position by its own weight acts on the special prize opening / closing member 53, so the second special prize opening 51 The special prize opening opening / closing member 53 can be more stably held in the closed position where the special prize opening opening / closing member 53 is closed, and unauthorized opening of the special prize opening opening / closing member 53 can be more effectively prevented. In addition, by providing the second decorative portion 53c of the special prize opening / closing member 53 with the protrusion 53d, the special prize opening opening / closing member 53 can be more reliably held in the closed position where the second special prize opening 51 is closed. Can do. Then, by energizing the special prize opening / closing member 53 to the closed position, it is possible to effectively prevent the second special prize opening 51 from being inadvertently opened due to vibration or the like. Unintentional winning to 51 can be prevented. In addition, since the second special prize solenoid 52 is arranged in such a posture that the plunger 52a protrudes downward when not driven, the operation member 86 is urged to the lock position by the action of the plunger 52a. Unauthorized opening of the mouth opening / closing member 53 can be prevented more effectively.
