  As shown in FIG.3 and FIG.4, the rear surface of this rail decoration frame 23 is comprised from the hollow. The side wall 40 provided with the opening 41 is formed of a substantially arc-shaped side wall. Inside the side wall and above the opening 41, a guide piece 45 for guiding the moving direction of a shutter 60 described later is provided. The guide piece 45 has a substantially L-shaped cross section orthogonal to the longitudinal direction. The longitudinal direction of the guide piece 45 is provided along the side wall 40 of the rail decoration frame 23. One piece 45 a of the guide piece 45 is inserted into a rail groove 62 provided in the shutter 60.

  A boss 46 is provided below the guide piece 45. The boss 46 is provided with a screw hole 46a so as to be coaxial with the central axis. A screw 47 inserted into an insertion hole 64a provided in the gear 64 is screwed into the screw hole 46a. Since the screw 47 is formed with the screw portion 47b only at the tip portion of the shaft portion 47a, the screw 47 is screwed into the screw hole 46a of the boss 46 so that the shaft portion 47a of the screw 47 is , The rotation axis of the gear 64.

  The rail decoration frame 23 is provided with a collection basket 50 below the opening 41. The collection basket 50 is provided for guiding the game ball 80 that has entered the opening 41 to the back side of the pachinko machine 2 and collecting it, for example, to a collection device provided in the game hall. The collection basket 50 includes a dropping unit 51 that drops the game ball 80 that has entered from the opening 41, and a rolling unit 52 that rolls the falling game ball 80. Between the falling part 51 and the rolling part 52, groove parts 53 and 54 into which a game ball detection sensor (game ball detection means) 74 described later is inserted are provided.

  Further, a stopper 55 is provided on the inner side of the rail decorative frame 23 and on the downstream side (out port 33 side) of the opening 41. The stopper 55 stops the movement of the shutter 60 in the direction of FIG. 6 when the shutter 60 moving in the direction of FIG. Thereby, the shutter 60 is held at a position where the opening 41 is blocked (hereinafter referred to as a closed position).

  The shutter 60 moves inside the rail decoration frame 23 along the side wall 40 of the rail decoration frame 23 between a closed position and a position where the opening 41 is opened (hereinafter, “open position”). The shutter 60 has a substantially arc shape, and a rack 61 and a rail groove 62 are provided on one surface thereof. The rack 61 meshes with a gear 64 screwed to the boss 46. The rail groove 62 is provided along the longitudinal direction of the shutter 55. When the shutter 60 is assembled to the rail decoration frame 23, the shutter 60 is assembled while the guide piece 45 of the rail decoration frame 23 is inserted into the rail groove 62. At this time, the shutter 60 is positioned between the inner wall surface 40 a of the side wall 40 of the rail decoration frame 23 and the guide piece 45. Note that a surface 60a (see FIG. 5) opposite to the surface on which the rack 61 and the rail groove 62 are provided is a surface exposed from the opening when the shutter 60 is in the closed position.

  The drive motor 65 is provided for moving the shutter 60. A gear 68 is fixed to the drive shaft 67 of the drive motor 65. When the drive motor 67 is driven, the drive force is transmitted to the gear 64 via the gear 67. Since the gear 64 meshes with the rack 61 of the shutter 60, for example, when the shutter 60 is in the closed position, when the drive motor 65 is driven and the gear 68 is rotated in the direction A in FIG. 5 rotates in the B direction, and the shutter 60 moves in the C direction in FIG. Further, when the gear 68 is rotated in the direction D in FIG. 6 when the shutter 60 is in the open position, the gear 64 is rotated in the direction E in FIG. 6 and the shutter 60 is moved in the direction F in FIG. A drive device 69 is configured by the drive motor 65 and the gears 64 and 68.

  The drive motor 65 is fixed to the bracket 70 with screws 71. The bracket 70 is assembled and fixed to the back surface 21 a of the game board 21 with screws 72. When the bracket 70 is fixed to the back surface 21 a of the game board 21, the drive motor 65 is inserted through the insertion hole 21 b provided in the game board 21. Reference numeral 70a denotes an insertion hole through which a screw is inserted, and reference numeral 21c denotes a screw hole into which the screw 72 is screwed. Reference numeral 21d denotes an insertion hole through which the rolling part 52 of the recovery rod 50 is inserted.

  The game ball detection sensor 74 is provided for detecting the game ball 80 falling on the collection basket 50. When the game ball 80 is detected by the game ball detection sensor 74, the detection signal is output to the game control device (drive control means) 75. Upon receiving this detection signal, the game control device 75 drives the payout device 16 to pay out a predetermined number of game balls 80 to the supply tray 10 as prize balls.

  Next, the operation of this embodiment will be described. As shown in FIG. 5, when a game is not being performed, or when a game is performed in a normal state in which a normal game is performed, the shutter 60 is held in the closed position, and the opening 41 is a shutter. 60 is shielded. At this time, when a game is performed, the game ball 80 is bounced from the upper side of the game area 35 to the obstruction nail or windmill disposed on the game board 21 or the side wall of the center accessory 25, so Flow down while changing. Then, when winning the winning chucker 28 or the starting chucker 27, a game ball 80 as a winning ball corresponding to the winning is paid out from the payout device 16 to the supply tray 10. On the other hand, the game ball 80 that does not win the winning chucker 28 or the starter chucker 27 or the game ball 80 that flows down along the side wall 40 of the rail decoration frame 23 may reach the opening 41. Since it is shielded, the game ball 80 moves toward the out port 33 without entering the opening 41. At this time, the inclined surface 41 a provided at the peripheral edge of the opening 41 rolls along the side wall 40 of the rail decorative frame 23 without being caught by the side edge of the opening 41.

  When the game ball 80 wins the starting chucker 27 when a game is performed, a lottery for determining whether or not to win and a lottery for determining whether the winning type is “big hit” or “medium hit” are performed. In the case where these lotteries result in “hit”, the game control device 75 shifts the gaming state from the normal state to the “hit” state. In the “hit” state, the attacker 29 is temporarily closed when, for example, 30 seconds elapses after the attacker 29 is released, or when 10 game balls 80 are won, for example. If ten game balls 80 are won when the attacker 29 is released once, the attacker 29 is released again. By performing this operation at most, for example, 15 times, the “big hit” state is terminated. In this “hit” state, the game balls 80 can easily win the big winning opening provided inside the attacker 29. Therefore, more game balls 80 can be won than in the normal state, and more prize balls are obtained. be able to.

  On the other hand, in the above-described lottery, when the game becomes “medium hit”, the gaming state becomes the “medium hit” state. In the “medium hit state”, the game control device 75 drives the drive motor 65 to rotate the gear 68 in the direction A in FIG. As the gear 68 rotates in the direction A in FIG. 5, the gear 64 rotates in the direction B in FIG. 5, so that the shutter 60 moves along the side wall 40 of the rail decoration frame 23 (in the direction C in FIG. 5). As the shutter 60 moves in the direction C in FIG. 5, the shutter 60 moves from the closed position to the open position. As a result, the opening 41 is opened and the game ball 80 can win the opening 41. Note that the game control device 75 stores in advance the time for which the drive motor 65 is driven, so that if the time for which the drive motor 65 is driven reaches a predetermined time, the game control device 75 causes the drive motor 65 to be driven. Stop driving.

  When the opening 41 is opened, for example, a gaming ball 80 that flows down along the side wall 40 of the rail decoration frame 23 or a gaming ball 80 that does not win the winning chucker 28 or the starting chucker 27 is received by the opening 41. It is done. As shown in FIG. 6, when the game ball 80 is received in the opening 41, the game ball 80 falls on the drop part 51 of the collection basket 50. Thereafter, when the game ball 80 passes through the opening 74 a of the game ball detection sensor 74, the game ball 80 is detected, and the detection signal is output to the game control device 75. That is, the game ball 80 is won by detecting the game ball 80 by the game ball detection sensor 74. When this detection signal is output to the game control device 75, the game control device 75 drives the payout device 16 to pay out the game ball 80 as a prize ball to the supply tray 10. In this case, the number of game balls 80 to be paid out when winning the attacker 29 or the number of game balls 80 to be paid out is paid out. The game balls 80 collected by the collection basket 50 are guided to the back side of the pachinko machine 2 and collected by a collection device provided in the island facility of the game hall.

  In this “medium hit” state, for example, if either 15 seconds have elapsed after the opening 41 is opened or five game balls 80 are awarded, the game control device 75 causes the drive motor 75 to 65 is driven, and the gear 68 is rotated in the direction D in FIG. In accordance with this rotation, the gear 64 rotates in the E direction in FIG. 6, so that the shutter 60 moves along the side wall 40 of the rail decoration frame 23 (F direction in FIG. 6). When the shutter 60 moves in the direction F in FIG. 6, the shutter 60 comes into contact with the stopper 55, and the movement of the shutter 60 is stopped. By stopping the shutter 60, the shutter 60 is held in the closed position. Also in this case, the game control device 75 stops the driving of the driving motor 65 when the driving time of the driving motor 65 reaches a predetermined time. As a result, the opening 41 is shielded by the shutter 60, so that even if the game ball 80 flowing down the game area 35 reaches the opening 41, it does not enter the opening 41 but toward the out port 33, and the rail decoration frame It rolls along the side wall 40 of 23.

  In this “medium hit” state, when five game balls 80 enter when the opening 41 is opened once, the opening 41 is opened again. When the opening 41 is opened seven times, the “medium hit” state ends, and the state where the opening 41 is shielded by the shutter 60 is maintained. As a result, in the “medium hit” state, although not as much as the “big hit” state, a large number of game balls 80 can be won, so that more prize balls than in the normal state can be obtained. As a result, the game board can be provided without providing the function of the attacker in the game area, so that it is possible to secure a flow path for the game balls flowing down the game area.

  In the present embodiment, in the game control device, the time for driving the drive motor is stored in advance, and when the time for driving the drive motor reaches a predetermined time, the drive of the drive motor is stopped. However, the present invention is not limited to this. For example, a plurality of photointerrupters (hereinafter referred to as PIs) for detecting an index on a shutter and an index on a rail decoration plate are provided, and whether or not the shutter has moved to a closed position by these PIs, Or it may be made to detect whether it moved to an open position and to stop a drive motor, when an index is detected.

  In the present embodiment, the shutter is moved along the inside of the side wall of the rail decorative frame, but the present invention is not limited to this. For example, the shutter is along the side wall of the rail decorative board and facing the game area. Can also be moved.

  In this embodiment, the case where there is one opening provided on the side wall of the rail decorative frame has been described. However, the number of openings need not be limited to one, and a plurality of openings may be provided as long as they are downstream of the game area. It is also possible.

  In the present embodiment, the game area 35 of the game board unit 20 is provided with the attacker 29. However, the present invention is not limited to this, and the game board unit can be used in a game board unit that does not have the attacker 29. In this case, it can be used as an attacker by sliding the shutter 60 provided on the rail decoration frame to open and close the opening 41 during the big hit state.

  In the present embodiment, the shutter that shields the opening is configured to move along the inside of the side wall of the rail decoration frame and on a plane parallel to the board surface of the game board. However, the present invention is not limited to this. The shutter may be moved in a direction orthogonal to the board surface. As shown in FIGS. 7 and 8, in this case, an opening 92 is provided on the side wall 91 of the rail decorative frame 90, and a collection basket 93 continuous with the opening 92 is provided inside the rail decorative frame 90. The collection basket 93 is L-shaped like the collection basket of this embodiment, and a game ball detection sensor (game ball detection means) 96 is assembled to the lowermost end of the drop portion 94. On the other hand, the game board 97 is provided with an insertion hole 98 into which a shutter (movable object) 99 having a hexagonal cross section is inserted.

  The shutter 99 inserted through the insertion hole 98 has a curved surface in which an upper surface (surface facing the game area 103) 99a and a lower surface (surface facing the opening 92) 99c are curved so that the lower surface 99c side is convex. Composed. Further, on the upper surface 99a of the shutter 99, the upstream end edge portion and the downstream end edge portion of the rail decorative frame 90 are inclined surfaces 99c and 99d that are inclined downward toward the side wall 91 of the rail decorative frame 90. Each is provided. The shutter 99 is slid in a direction perpendicular to the board surface of the game board 97 (J direction in FIG. 7 or K direction in FIG. 8) by, for example, a solenoid or a driving device 100 including a gear mechanism and a driving motor. That is, it slides between a closed position (see FIG. 7) where the driving device 100 covers the opening 92 and an open position (see FIG. 8) where the opening 92 is exposed. When the shutter 99 is slid to the open position, the shutter 99 is accommodated in an insertion hole 98 provided in the game board 97.

  For example, when the shutter 99 is in the closed position, since the opening 92 is covered with the shutter 99, the game ball 105 is in the order of the inclined surface 99c, the upper surface 99a, and the inclined surface 99d of the shutter 99 (L in FIG. 7). After rolling (in the direction), it rolls along the side wall 91 of the rail decoration plate 90 again. On the other hand, when the drive device 100 is driven in response to a drive signal from the game control device (drive control means) 101, the shutter 99 slides from the closed position to the open position (in the J direction in FIG. 7). Thereby, the opening 92 is exposed. In this state, the game ball falling in the game area 103 or the game ball 105 flowing down along the side wall 91 of the rail decoration frame 90 falls from the opening 92 into the rail decoration frame 90.

The game ball 105 dropped from the opening 92 into the rail decoration frame 90 falls on the dropping portion 94 of the collection basket 93 and passes through the opening 96 a provided in the game ball detection sensor 96. During the passage of the opening 96a, it is detected that the game ball 105 has passed, and the detection signal is output to the game control device 101. In response to this, the game control device 101 drives the payout device 106 to pay out the game ball 105 as a prize ball. The game ball 105 that has passed through the opening 96a of the game ball detection sensor 96 rolls inside the rolling portion 95 of the collection basket 93, and is then collected into a collection device provided in the island facility of the game hall. . Further, when covering the opening 92, the driving device 100 is driven, and the shutter 99 is moved in the K direction in FIG. Thereby, the opening 92 is covered by the shutter 99, and the game ball 105 flowing down the game area 103 does not fall into the rail decoration frame 90 from the opening 92, but flows down along the side wall 91 of the rail decoration frame 90, It is collected from the outlet.
