Description

  The present invention relates to a pachinko machine that uses a game ball to play a game, and more particularly, to a pachinko machine equipped with an attacker device that is opened when a big hit occurs.

  In the pachinko machine, the board surface of the game board is divided into a substantially circular game area by a guide rail, and a variable display device, a start winning opening, an attacker device, etc. are arranged in this game area and directed toward the game area. There is a model in which an electronic lottery is performed in response to the game ball that has been launched at the start winning opening, and the variable display device displays a variable display and a stop display based on the lottery result. The lottery result of the electronic lottery has a win and a loss, and when the lottery result is a win, a combination of predetermined special symbols is displayed on the display screen of the variable display device, and the mode shifts from the normal mode to the special game mode. In this special game mode, the opening / closing door of the attacker device opens to expose the grand prize opening, so that it becomes easy for a game ball to enter the exposed big prize opening and the player can acquire many prize balls. . In addition, game balls that have not won any of the winning prize openings such as the start prize opening and the big prize opening slide on the curved lower sliding surface of the guide rail and are guided to the lowermost part of the gaming area. It is discharged to the back side of the game board from the out port provided at the lowest position. For this reason, a guide surface that inclines with a downward slope toward the out port is generally provided at the lowest position of the lower sliding surface of the guide rail, and the game ball that has slid to the lowest position of the guide rail is guided to the guide surface. The direction is changed diagonally backward and led to the outlet.

  Conventionally, in such a pachinko machine, two attacker devices are stacked and arranged in two upper and lower stages, and both of these attacker devices are arranged in the space between the variable display device and the out port, so that the space of the game board There has been proposed an attacker device called a double attacker that saves the amount of money and changes the winning mode (for example, see Patent Document 1).

JP 2006-187309 A

  By the way, in recent years, variable display devices tend to be increasingly larger, and when such a large variable display device is arranged in the center of the game area, a gap between the variable display device and the outlet is accordingly accompanied. Therefore, it is difficult to sufficiently separate the attacker device from the outlet. As a result, when the game ball that slides on the guide rail jumps up due to the steps generated on the left and right sides of the guide surface, the game ball easily collides with the opening / closing door of the attacker device, and the attacker device that should have been closed malfunctions. The problem occurs. In particular, when a double attacker in which two attacker devices are stacked in two upper and lower stages is adopted, the separation distance between the lower-stage attacker device and the out port becomes extremely short, so the above-described problem is remarkable. Become.

  The present invention has been made in view of the situation of the prior art as described above, and an object thereof is to provide a pachinko machine that can prevent an erroneous operation of an attacker device caused by a jump of a game ball.

  In order to achieve the above object, the present invention provides a game board having a substantially circular game area partitioned by guide rails, an out port provided at the lowest position of the game area, An pachinko machine that opens and closes the winning prize opening based on the result of electronic lottery. A guide surface that is inclined downward toward the out port is provided, and a step is formed at the boundary between the lower sliding surface and the guide surface that gradually increases the height dimension toward the out port. A regulating plate extending in the left-right direction along the lower sliding surface is provided on the front surface of the game board, and the regulating plate surrounds the out port and extends between the opening and closing door and from the opening and closing door. Also left and right Extending in the direction, the plate thickness of the restriction plate is set to be maximized at the central portion from the periphery of the out-port to the vicinity of both ends in the left-right direction of the open / close door, and gradually thinner toward the outside, and The central portion of the restricting plate is planarly overlapped with the inner portion of the guide surface, and the central portion projects forward from the open / close door in the closed state.

  In the pachinko machine configured as described above, a restricting plate extending toward the out port is provided on the back side of the lower sliding surface of the guide rail. The restricting plate surrounds the out port and extends between the opening and closing door. Extending in the left and right direction than the opening and closing door, the thickness of the restriction plate is maximized at the center from the periphery of the out port to the vicinity of both ends in the left and right direction of the opening and closing door, and gradually becomes thinner toward the outside. And the central portion of the regulating plate is planarly overlapped with the inner portion of the guide surface provided on the guide rail. For this reason, among the steps formed at the boundary between the lower sliding surface and the guide surface of the guide rail, the inner portion of the guide surface having the largest step is covered from above by the central portion of the regulation plate. Accordingly, the game ball that slides on the lower sliding surface of the guide rail and moves toward the guide surface is regulated to the front side of the guide surface with a small step by the regulation plate, and then guided to the out-port by the descending slope of the guide surface. As a result, the jumping at the level difference of the game ball sliding on the guide rail is minimized. Therefore, even if the attacker device is disposed close to the outlet, it is possible to prevent the open / close door of the attacker device from malfunctioning due to the jumping up of the game ball.

  The pachinko machine of the present invention is provided with a restricting plate extending toward the out port on the back side of the lower sliding surface of the guide rail that divides the game area, and the restricting plate has a maximum thickness at the center and is on the outside. As the thickness of the guide plate is gradually reduced toward the guide rail, the center of the regulation plate overlaps with the depth of the guide surface provided on the guide rail so that the lower surface of the guide rail slides toward the guide surface. After restricting the position of the sphere to the front side of the guide surface with a small step by the restricting plate, the ball can be guided to the out port using the descending slope of the guide surface. Therefore, the jumping of the game ball that slides on the guide rail at the level difference is minimized, and even if the attacker device is placed close to the outlet, the door of the attack device malfunctions due to the jump of the game ball. Can be prevented.

A shaped accessory 22 is used. Although not shown in the figure, the accessory 22 is supported by the tip of an arm that is pivotally supported on the inner side of the right wall of the decorative frame 14. For example, when the arm is rotated around the shaft during super-reach, The object 22 moves up and down along the front surface of the variable display device 16.

  Further, an attacker unit 23 is disposed immediately below the second start winning opening 20, and a first attacker device 24 and a second attacker device 25 are arranged close to the upper and lower stages in this attacker unit 23. . Although the detailed structure of the attacker unit 23 will be described later, the first attacker device 24 on the upper stage side includes a large winning opening that opens in a horizontally long front surface, a sensor unit that detects a game ball won in the large winning opening, An attacker door that opens and closes the opening of the big prize opening, a solenoid that drives the attacker door, and the like are provided, and the second attacker device 25 on the lower stage side is similarly configured. These attacker devices 24, 25 win a big hit game as a result of an electronic lottery concerning a special symbol that is triggered when a game ball wins at one of the first and second start winning ports 19, 20 This device is activated when the state (special game mode) is entered. Specifically, if the lottery result of the special symbol is a first jackpot (for example, a normal jackpot), the attacker door of the first attacker device 24 is repeatedly opened several times to expose the special winning opening, When the lottery result is a second jackpot (for example, a promising jackpot), the attacker door of the second attacker device 25 is repeatedly opened several times to expose the big winning opening. The attacker door of the first attacker device 24 is kept open until, for example, 30 seconds elapses for one opening operation or until 10 game balls are won in the big winning opening, during which one winning Then, for example, 12 pieces are paid out as prize balls, and after the opening operation is repeated, for example, 14 times, the jackpot ends. Similarly, the attacker door of the second attacker device 25 is kept open until, for example, 30 seconds elapses for one opening operation, or until 10 gaming balls are won at the big winning opening, during which one For example, 15 winning balls are paid out as winning balls, and after the opening operation is repeated, for example, 17 times, the jackpot ends.

  In addition, in the game area 12, a plurality of general winning holes 26 for only paying out game balls, a game nail 27 and a windmill 28 that carry the flow path of the game balls, and the like are provided. The game balls that have not won 19 or 20 or the general winning opening 26 are discharged to the back side of the game board 3 from the out opening 29 provided at the lowermost end of the gaming area 12.

  As shown in FIGS. 3 to 6, the attacker unit 23 includes a unit case 30 made of a synthetic resin in which a big prize opening 30 a of the first attacker apparatus 24 and a big prize opening 30 b of the second attacker apparatus 25 are formed, A decorative board 31 fixed to the front surface of the unit case 30 by screwing or the like, a first attacker door 32 for opening and closing the upper prize winning opening 30a, and a second attacker door 33 for opening and closing the lower prize winning opening 30b. A solenoid 34 that drives the first attacker door 32, a solenoid 35 that drives the second attacker door 33, a sensor unit (not shown) that detects a game ball that has won a big winning opening 30a on the upper side, and a lower side A sensor unit 36 for detecting a game ball won in the big prize opening 30b. Note that the upper prize-winning opening 30a and the lower prize-winning opening 30b are both formed in a horizontally-long rectangular shape, but the horizontal dimensions are not the same. It is set longer.

  The unit case 30 is housed in a space cut out in the game board 3, and the outer edge portion of the decorative board 31 integrated with the unit case 30 is screwed to the front surface of the game board 3, so that the attacker unit 23 is fixed to the game board 3. The decorative plate 31 is a plate-like member obtained by performing metal plating on a synthetic resin molded product, and a notch 31a for defining the upper edge of the out port 29 is formed at the center of the lower side. In addition, a regulation plate 31 b is integrally formed on the lower side portion of the decorative plate 31, and the regulation plate 31 b extends in an arc shape along the back side of the sliding surface of the lower guide rail 11. On the sliding surface of the lower guide rail 11, a guide surface 11 a that is inclined downward toward the out port 29 is formed. By changing the direction, the game ball sliding on the lower guide rail 11 is surely guided to the out port 29. In addition, since the guide surface 11a is deeply inclined with respect to the sliding surface of the lower guide rail 11, a wedge-shaped step is generated in the boundary portion between the sliding surface of the lower guide rail 11 and the guide surface 11a in a side view. As shown in FIG. 6, the height of the step gradually increases from the front side to the back side of the guide surface 11a.

  The thickness of the restricting plate 31b is maximum at the central portion including the periphery of the notch 31a, and has a tapered shape that gradually decreases from the central portion toward the left and right outer sides (see FIG. 4). As shown in FIG. 6, the central portion of the regulation plate 31 b overlaps with the inner portion of the guide surface 11 a in a planar manner, and among the steps generated at the boundary between the sliding surface of the guide rail 11 and the guide surface 11 a, The back part of the guide surface 11a having the largest step is covered from above by the center part of the regulating plate 31b. As shown in the figure, the central portion of the regulation plate 31b protrudes forward from the first attacker door 32 in the closed state and the second attacker door 33 in the closed state.

  The first attacker door 32 is a horizontally long plate-like body, and a pair of left and right shaft portions provided on the lower end side thereof are rotatably supported between the unit case 30 and the decorative plate 31. Normally, the first attacker door 32 is held in an upright position that closes the upper prize-winning opening 30a. However, the energization of the solenoid 34 rotates to the near side to open the big prize-winning opening 30a. The second attacker door 33 is also a horizontally long plate-like body, and a pair of left and right shaft portions provided on the lower end side thereof are rotatably supported between the unit case 30 and the decorative plate 31. Normally, the second attacker door 33 is held in an upright posture to close the lower prize-winning port 30b, but is turned to the near side by energizing the solenoid 35 to open the big prize-winning port 30b. As described above, since the large winning opening 30b on the lower side is formed slightly larger than the large winning opening 30a on the upper stage, the second attacker is set larger than the first attacker door 32 so as to correspond thereto. The door 33 is formed somewhat larger. The lower second attacker door 33 is disposed at a position immediately above the out port 29 (notch 31 a), and the center of the regulation plate 31 b is between the second attacker door 33 and the out port 29. The department is extended. In addition, guide members 37 that are inclined toward the lower prize-winning opening 30b are fixed to the front surface of the decorative board 31 one by one on the left and right sides, and when the second attacker door 33 is opened, these guides are provided. The member 37 can guide the game ball to the big winning opening 30b of the second attacker device 25.

  As described above, in the pachinko machine P according to this embodiment, the restricting plate 31b extending toward the out port 29 is provided on the back side of the sliding surface of the lower guide rail 11 that defines the lower portion of the gaming area 12. The thickness of the restricting plate 31b is maximized at the central portion and is set to be gradually thinner toward the outside, and the central portion of the restricting plate 31b is formed at the bottom of the lower guide rail 11 at the back of the guide surface 11a. Of the guide surface 11a having the largest step among the wedge-shaped step formed at the boundary between the sliding surface of the lower guide rail 11 and the guide surface 11a. It will be covered from above by the central part. Therefore, the position of the game ball that slides on the sliding surface of the lower guide rail 11 toward the guide surface 11a is regulated to the front side of the guide surface 11a with a small step by the taper shape of the regulation plate 31b, and then descends on the guide surface 11a. It will be guided to the out port 29 by the gradient, and the jumping at the level difference of the game ball sliding on the lower guide rail 11 can be minimized. Therefore, even if the second attacker device 25 is disposed close to the outlet 29, the second attacker door 33 of the second attacker device 25 is undesirably opened due to the jumping of the game ball. Can be prevented.

  In addition, an attacker unit 23 having a double attacker structure in which the first attacker device 24 and the second attacker device 25 are arranged close to each other in two upper and lower stages is adopted, and the lower side portion of the decorative plate 31 fixed to the front surface of the attacker unit 23 is regulated. The board 31b is integrally formed, and the guide members 37 for guiding the game balls to the second attacker device 25 on the lower side are provided on the front surface of the decorative board 31 one by one on the left and right sides. While being able to be compactly arranged above the mouth 29 and when the second attacker door 33 of the second attacker device 25 is opened, the game ball is moved by the pair of left and right guide members 37 of the second attacker device 25. It can be led to the big prize opening 30b.

  In the above embodiment, the case where the regulation plate 31b is integrally formed on the lower side portion of the decorative plate 31 provided on the front surface of the attacker unit 23 has been described. However, the regulation plate 31b is separated from the decorative plate 31. It can also be configured as a single part.

  In the above-described embodiment, the case where the double attacker structure of the attacker unit 23 in which the first attacker device 24 and the second attacker device 25 are arranged close to each other in two upper and lower stages has been described. The present invention can also be applied to a pachinko machine in which only one attacker device is arranged on the upper side, and in this case, the attacker device can be arranged close to the out port, so that the degree of freedom in design is improved.
