Description

  The present invention relates to a gaming machine.

  In a gaming machine such as a pachinko machine, an inner frame is assembled to a rectangular outer frame so as to be opened and closed, and a front frame is provided on the inner frame so as to be opened and closed. A game board is detachably attached to the front side of the inner frame visible from the player. In addition, a ball tray is provided on the front frame. The game balls stored in the ball tray are guided to the launch position of the launch device, and the launch device is operated by operating the launch handle provided on the front frame.

  In addition, on the back side of the inner frame, a storage tank that stores game balls supplied from the island of the hall in each pachinko machine, a tank rail that guides the game balls of the storage tank downstream, and the ball pressure is distributed from the tank rail There is provided a ball passage that allows the game ball to flow down and a game payout device for paying out a game ball as a winning ball or a rental ball based on a predetermined condition. A game ball paid out from the inner frame opening through the payout path from the ball payout device is temporarily stored in a ball tray provided on the front frame.

  Hall clerk may open front frame to check pachinko machine in game and clear ball clogging. At this time, if the ball tray is full and is filled with game balls paid out from the ball paying device to the ball payout passage, or if the winning ball is paid out by winning a prize, the inner frame opening or opening is opened. There is a possibility that game balls staying in the front frame will fall down.

  In order to eliminate such a problem, a shutter mechanism that can be opened and closed is provided in a part of the ball payout passage of the inner frame. When the front frame is closed, the shutter mechanism is in a position where the shutter is retracted from the ball payout passage, and with the opening operation of the front frame, the ball payout passage is blocked with the interlocking lever blocking portion facing the shutter, and the game ball is spilled. (Refer to Patent Document 1).

Japanese Patent No. 4195340

In the gaming machine of Patent Document 1 described above, when the front frame is opened, depending on the accumulated state of the game balls paid out to the ball payout passage, the game ball is blocked when the shutter blocks the ball payout passage. There is a risk of biting between parts (so-called spherical biting) (see Patent Document 1; FIG. 14).
If the front frame is opened while the ball is bitten, the game ball that has been bitten is in an unstable state and may spill. May also scatter.

  An object of the present invention is to solve the above-mentioned problems of the prior art, and to prevent a ball spilling due to ball engagement of a game ball remaining in a ball passage provided with a shutter mechanism when the front frame is opened from the inner frame Is to provide.

In order to achieve the above object, the present invention comprises the following configuration.
A front frame provided on the front side of the inner frame for holding the game board so as to be openable and closable via a hinge, and a predetermined number of game balls paid out from a ball payout device provided on the inner frame Side upstream ball guide rod and the front frame side downstream ball guide rod are connected to a ball tray through a ball guide path formed in communication with the upstream ball guide rod, An open position for allowing a game ball to flow down to the ball receiving tray through a ball guiding path formed by retreating from the ball guiding path with the front frame closed and communicating with a downstream ball guiding rod; and the front frame Is opened, the shutter member is provided so as to be movable between a blocking position that enters the ball guiding path and blocks the game ball from flowing down to the downstream ball guiding rod, and the shutter member moves forward and backward. It is pivotally supported on the opposite surface side of the moving ball guiding path so as to be swingable, It characterized in that the surface frame has anda rocking member of blocking the game ball falls spill by the cooperation with the shutter member when it is opened.

  The swing member swings when a game ball is pressed against the ball contact surface forming the ball guide path by the shutter member.

  The shutter member and the swinging member are connected via a biasing member and biased in a direction that is always drawn so as to be relatively close to each other. When the front frame is opened, the shutter member swings. It is drawn toward the moving member and moves to the blocking position.

  Further, when the front frame is opened, when the shutter member blocks the ball guiding path and the game ball existing in the ball guiding path is sandwiched between the swinging member, the sandwiched game ball is The swing member swings so as to retreat from the ball guide path.

  If the above-described gaming machine is used, the shutter member is in the open position withdrawn from the ball guide path when the front frame is closed, so that the upstream ball guide rod and the downstream ball guide rod are formed in communication with each other. The game ball flows down to the ball tray on the ball guide path. Further, when the front frame is opened, the ball enters the ball guiding path and moves to a blocking position where the game ball is prevented from flowing down to the downstream ball guiding rod and is pivotally supported on the opposite surface side of the ball guiding path. The spilling of the game ball is blocked by the cooperation with the swing member. Since the swinging member on the opposite surface side of the ball guide path can swing when the shutter member is closed, the ball biting is unlikely to occur and the ball spilling due to the ball biting can be prevented.

  Further, since the swinging member swings when the game ball is pressed against the ball contact surface forming the ball guide path by the shutter member, an unstable ball engagement state by the shutter member due to the opening of the front frame occurs. It becomes difficult.

  Further, when the shutter member and the swinging member are connected via a biasing member so as to be relatively close to each other and biased in a direction that is always drawn, the upstream ball guiding rod and the downstream ball guiding rod Even if a game ball is present on the ball guide path, which is the boundary, the shutter member and the swinging member are relatively close to each other, thereby blocking the ball guide path and preventing the game ball from falling.

In addition, when the front frame is closed, the shutter member is in the open position where it is retracted from the ball guide path, so that the swinging member is attracted to the ball guide path side by the urging member. Therefore, even if the game ball collides with the swinging member while the game ball is flowing down the ball passage, the swinging member does not swing greatly, so that the flow of the game ball is not affected.
Further, when the front frame is open, the shutter member is in the blocking position where it enters the ball guide path, so that the tip of the swing member is played by the game ball pushed to the opposite surface side (the swing member side) by the shutter member. Even if the part swings to a position away from the ball guide path, the urging member attracts the shutter member to the ball guide path side, so that the blocking position can be reliably held. Therefore, it is possible to prevent the ball from spilling due to the opening / closing operation of the front frame.

  Further, when the front frame is opened, if the shutter member blocks the ball guiding path and the game ball existing in the ball guiding path is sandwiched between the swinging members, the sandwiched game ball is moved to the ball guiding path. The swing member swings so as to be retracted. Therefore, since the game ball is sandwiched between the ball contact surface of the swinging swinging member, the subsequent ball, and the shutter member, an unstable ball-engagement state does not occur, which is caused by the ball engagement. Ball spillage can be reliably prevented.

It has been.

  In FIG. 2, a storage tank 19 is provided on the upper side on the back side of the inner frame 3, and game balls are supplied to the storage tank 19 from the island of the hole where the pachinko machine 1 is arranged. The storage tank 19 is formed so that the bottom part inclines downward toward the tank rail 20 provided on the downstream side in the ball supply direction (the right end side in FIG. 2). The tank rail 20 is connected to a ball dispensing device 22 through a ball passage 21 that flows down in the vertical direction. The ball payout device 22 pays out game balls supplied from the ball passage 21 in order as rental balls and prize balls. The game balls paid out from the ball payout device 22 are passed through the ball payout passage 22a, and the upstream ball guide rod 23 provided in the inner frame 3 and the downstream ball guide rod 24 provided in the lower front frame 5b (see FIG. 3). Through the opening 5c to the ball tray 9 (see FIG. 1).

  The back side of the game board 6 is covered with a board cover 25. The panel back cover 25 covers the symbol display device 11 and an image processing board (not shown) for controlling the symbol display device 11. Further, the main control board that performs overall control of the gaming operations of the pachinko machine 1 is housed and sealed in the board housing case 26. Although not shown, in addition to the main control board, a payout control board for controlling the operation of the ball payout device 22, a launch control board for controlling the operation of the ball launcher (not shown), and the like are provided.

  A locking device 28 connected to the cylinder lock 27 (see FIG. 1) is provided on the open end side (left end side in FIG. 2) of the inner frame 3. When the cylinder lock 27 is inserted and rotated in one direction, the outer frame 2 and the inner frame 3 are unlocked, and when rotated in the other direction, the upper front frame 5a and the inner frame 3 are unlocked.

  Next, the configuration of the ball guiding path of the game ball paid out from the ball payout device 22 will be described with reference to FIGS. As shown in FIG. 3, an upstream ball guide rod 23 and a downstream ball guide rod 24 provided on the lower front frame 5b side communicate with a predetermined number of game balls paid out from the ball dispenser 22 (see FIG. 2). The ball guide path 30 (see FIG. 6B) formed in this manner is paid out to the ball tray 9 (see FIG. 1).

In FIG. 6B, the upstream side ball guide rod 23 is provided with a guide rod main body 23a that forms a ball passage. The ball guide cage main body 23a is formed with a ball passage 23c for guiding the game ball flowing down from the upper opening 23b by changing the direction in the front-rear direction.
The shutter member 29 opens and closes a ball guide path 30 formed by communicating the upstream ball guide rod 23 and the downstream ball guide rod 24. The shutter member 29 is assembled so as to be rotatable around a shaft pin 31 fitted in the guide rod main body 23a. An E-ring 32 (see FIG. 6A) is fitted to the shaft end of the shaft pin 31, and is prevented from coming off from the guide rod main body 23a. Since the shaft pin 31 is provided below the corner where the game ball flows down from the vertical direction to the front-rear direction in the ball passage 23c, the shutter member 29 has a compact turning radius around the shaft pin 31 on the upstream side. It can be assembled to the ball guide rod 23.

  When the lower front frame 5b is opened, the shutter member 29 is retracted from the ball guide path 30 formed with the lower front frame 5b closed and allows the game ball to flow down to the ball tray 9. It is provided so as to be able to rotate and move between a blocking position where the ball enters the ball guiding path 30 and blocks the game ball from flowing down to the downstream ball guiding rod 24. The shutter 29 is not limited to rotational movement, and may be configured to slide.

  The swing member 33 is assembled so as to be rotatable around a shaft pin 34 fitted in the guide rod main body 23a. An E-ring 35 (see FIG. 4A) is fitted to the shaft end of the shaft pin 34 to prevent it from coming off from the ball guide rod main body 23a. The swing member 33 is pivotally supported on the opposite surface side of the ball guide path 30 where the shutter member 29 advances and retreats so as to be swingable about the shaft pin 34, and cooperates with the shutter member 29 when the lower front frame 5b is opened. Work and stop the spilling game balls.

  When the lower front frame 5b is opened, the swinging member 33 forms a part of the ball guide path 30 when the game ball is blocked by the shutter member 29 (see FIG. 7), and the upstream side ball. A swing position in which a game ball existing in the ball guide path 30 that is a boundary between the guide rod 23 and the downstream ball guide rod 24 is pressed against the ball contact surface 33b by the shutter member 29 and swings (see FIG. 8). Is provided so as to be swingable.

In FIG. 5, locking portions 29 a protrude from both sides of the free end of the shutter member 29, and locking portions 34 a protrude from both sides of the free end of the swing member 33. . As shown in FIGS. 4A to 4C, a tension spring (biasing member) 36 is connected on both sides between the locking portion 29a and the locking portion 33a.
As a result, the shutter member 29 and the swing member 33 are always urged in a relatively attracting direction and assembled to the upstream side ball guide rod 23.

Further, the shaft pin 34 of the swing member 33 is provided at the downstream end of the upstream ball guide rod 23, and the swing member 33 is attached to the free end side upstream of the shaft pin 34 by the tension spring 36 in the pulling direction. It is energized. Therefore, even if the game ball collides with the swinging member 33 with the lower front frame 5b closed, the swinging member 33 does not swing significantly, so that it does not affect the flow of the game ball (see FIG. 6 (b)).
Further, when the lower front frame 5 b is opened, the tip of the swing member 33 swings to a position away from the ball guide path 30 by the game ball Y pressed against the ball contact surface 33 b by the shutter member 29. Even so, the shutter member 29 is attracted toward the ball guide path 30 by the tension spring 36, so that the blocking position can be reliably held (see FIG. 8). Therefore, it is possible to prevent the ball from spilling due to the opening / closing operation of the lower front frame 5b.

  In FIG. 3, a shutter switching unit 37 that moves the shutter member 29 from the blocking position to the open position is provided below the downstream ball guide rod 24. As shown in FIG. 6B, the shutter switching portion 37 has a metal stay 37a assembled at one end to the lower portion of the guide rod body 24a with a screw 37b. An abutting block 37c is fixed to the front end of the stay 37a facing the inner frame 3 by screws 37d. On the other hand, an abutting protrusion 29b is provided on the lower portion of the shutter member 29 in the vicinity of the shaft pin 31.

  As shown in FIG. 6B, in the state where the lower front frame 5b is closed, the tip end abutting block 37c of the stay 37a abuts against the abutting projection 29b and pushes, so that the shutter member 29 is pulled by the tension spring 36. Against the force, it rotates counterclockwise about the shaft pin 31 to the open position, and the ball guiding path 30 is in communication.

  Further, as shown in FIG. 7, with the opening operation of the lower front frame 5 b, the tip abutting block 37 c of the stay 37 a is separated from the abutting projection 29 b, so that the shutter member 29 is pivoted by the tension force of the tension spring 36. By rotating clockwise around the pin 31, the shutter member 29 moves to the blocking position so as to be close to the swinging member 33, thereby blocking the ball guide passage 30. As a result, the leading game ball Y existing in the upstream ball guide rod 23 is dammed up, so that no ball spills due to the opening of the lower front frame 5b. At this time, the swing member 33 is held at the guiding position because the game ball Y is not pressed against it.

  In FIG. 8, when the lower front frame 5b is opened, the shutter member 29 moves to the blocking position and blocks the ball guide path 30, but the upstream ball guide rod 23 and the downstream ball guide rod 24 In some cases, the game ball Y existing at the interface is sandwiched between the ball contact surface 33b of the swing member 33 (ball biting occurs). However, the game ball Y is pressed against the ball contact surface 33b by the shutter member 29, and the swinging member 33 swings around the shaft pin 34 in the counterclockwise direction to a predetermined swinging position. At this time, the shutter member 29 and the swing member 33 are relatively close to each other, and the ball contact surface 33b of the swing member 33 with the game ball Y swings toward the upstream side. In this state, the sphere contact surface 33b of 33, the following sphere, and the tip of the shutter member 29 are in contact with each other and are sandwiched at three points. As a result, an unstable ball-engaged state does not occur, and ball spilling can be reliably prevented.

The shutter member 29 and the swing member 33 are provided in the ball guiding path formed in the front-rear direction of the pachinko machine 1, but may be provided in the vertical ball guiding path.
Moreover, although the case where the front frame is divided | segmented into the upper front frame 5a and the lower front frame 5b was demonstrated, it is applicable also when the front frame is integrally formed.
In the above-described embodiment, a pachinko machine has been described as an example of a gaming machine. However, the present invention may be applied to other gaming machines such as a sparrow ball gaming machine and an arrangement ball gaming machine.
