Description

  The present invention relates to a ball ball game machine that is installed and used in a game hall such as a pachinko parlor, and more particularly to a ball ball game machine equipped with a stage for rolling a game ball and guiding it to a starting winning opening just below. Is.

  In general, a ball game machine represented by a pachinko machine is provided with an effect display device, a start winning opening, an attacker device, etc. in the game area of the game board, and the game launched toward the game area. When the ball wins the start winning opening, an electronic lottery for winning the jackpot is performed. The result of this electronic lottery is displayed on the effect display device, and when winning as a result of the electronic lottery, the winning display is displayed on the effect display device, which is advantageous to the player. Transition to the state. In this jackpot game state, the attacker device opens and closes a predetermined number of times and the game ball enters the big prize opening, so that the player is given a privilege that a lot of prize balls can be obtained.

  In such a ball game machine, usually, the effect display device is arranged in the opening of the frame-shaped case to constitute the center accessory device, and this center accessory device is arranged above the start winning opening. Yes. The lower frame of the frame-like case is provided with a stage on which the game ball can roll, and a guide part (groove or groove) for dropping the rolled game ball toward the start winning opening is provided at the center of the stage. Hole) is formed. Further, a warp passage having a hollow structure is provided in the side frame portion of the frame-like case, and when a game ball flowing down the game area enters the warp passage, the game ball is discharged from the exit of the warp passage onto the stage. It has become so.

  Conventionally, a movable member is arranged in a region where a game ball rolls on the stage, and the movable ball moves up and down to change the movement of the game ball rolling on the stage. A gaming machine has been proposed (see, for example, Patent Document 1). This bullet ball game machine includes a pair of movable members that can be converted into a first state and a second state, and a link mechanism that moves the movable members up and down. A ball receiving portion for receiving a ball is formed. Normally, the movable member is in the first state and does not protrude from the upper surface of the stage. However, when a game ball flowing down the game area wins the general prize opening, the link mechanism causes the movable member to move to the first state by the load of the game ball. Therefore, the game ball that rolls on the stage can easily enter the starting prize opening along the groove formed between the two movable members. In this way, the game rolls on the stage because the movable member moves up and down irregularly and appears on the upper surface of the stage depending on whether or not the game ball flowing down the game area wins the general prize opening. Randomness can be given to the movement of the sphere.

  However, in the conventional ball game machine described above, the game ball launched toward the game area does not roll so much on the stage through the warp passage, and the game ball won in the general prize opening. Because the link mechanism causes the movable member to protrude on the stage by the load of the load, the frequency of the movable member protruding at the timing when the game ball coming out of the warp path rolls on the stage is extremely low and movable. It was difficult to enhance the interest of the game due to the presence of the members. In addition, since the movable member does not move unless the game ball flowing down the game area wins the general prize opening, the player's consciousness is naturally removed from the stage when the game ball that has come out of the warp passage is rolling on the stage. From this point, it was difficult to enhance the fun of the game due to the presence of the movable member.

  The present invention has been made in view of the situation of the prior art as described above, and its purpose is a ball that can have various changes in the movement of the game ball discharged from the warp passage toward the stage. It is to provide a gaming machine.

In order to achieve the above object, the present invention provides a game board having a game area, a start winning opening provided in the game area, a structure in which a game ball can roll and a rolled game ball. And a warp passage that guides the game balls flowing down the game area onto the stage, and electronic lottery is performed when the game balls have won the start prize opening. In a ball game machine in which a privilege is given to the player when the lottery result is won, a branch stage is provided at the exit of the warp passage, and the branch stage communicates with the stage by a partition wall that can be raised and lowered with partitions and a second region communicating with the first region and another passage for the movable body where the upper surface in the first region an inclined guide portion is disposed swingably, lifting the drive means said partition wall Make it work By lifting operation of the partition wall is to be transmitted to the oscillating motion of the movable body with a time difference.

In the ball game machine configured as described above, when a game ball flowing down the game area enters the warp passage, the game ball is discharged from the exit of the warp passage to the branch stage, and then first the partition wall at the branch stage. Depending on the ascending / descending state, it is distributed to one of the first region and the second region. Then, the game balls distributed to the first area are changed in direction by the tilt guide part of the movable body that swings with a time difference from the lifting and lowering operation of the partition wall , and are guided onto the stage. The speed changes irregularly according to the tilt angle of the movable body, and the game balls distributed to the second area are guided to a path different from the stage. In other words, the game balls discharged from the exit of the warp passage to the branch stage are not only distributed to the stage and other passages by the lifting and lowering operation of the partition wall, but also swinging with a time difference from the lifting and lowering operation of the partition wall. Since the initial velocity toward the stage is also changed by the movable body, the behavior of the game ball discharged from the warp passage is not uniform, and this can enhance the interest of the game.

  In the above-described configuration, the movable body is swingable with the stage side as a fulcrum, and a driving unit is provided on the partition wall so as to be able to come into contact with and separate from the lower surface of the movable body. , A motor and a rack and pinion that converts the rotation of the motor into a lifting operation of the partition wall, the partition wall and the movable body are moved up and down with a time difference from one motor as a drive source. It is preferable that it can be operated.

According to the ball game machine of the present invention, the game balls discharged from the exit of the warp passage to the branch stage are not only distributed to the stage and other passages by the partition wall that moves up and down on the branch stage, but also the partition wall The initial speed toward the stage is also changed by the movable body that swings with a time difference from the up and down movement of the game, so the behavior of the game ball discharged from the warp passage is not uniform, and the interest of the game Can be increased.

  An embodiment of the invention will be described with reference to the drawings. As shown in FIG. 1, a pachinko machine (bullet ball game machine) P according to the present embodiment is a vertically rectangular shape installed in an island facility of a game hall. Machine frame 1, front frame 2 attached to machine frame 1 so as to be openable and closable, game board 3 to be described later housed inside front frame 2, and door-opening on the front of front frame 2 A glass door 5 having a large opening 4 formed in the center, a transparent glass plate 6 attached to the opening 4 of the glass door 5, and a lower opening of the front frame 2 A front board 8 having a tray 7 that can accommodate a game ball and a launching handle 9 attached to a corner of the front board 8 are provided.

  As shown in FIG. 2, the board surface (front surface) of the game board 3 is a game area 11 surrounded by guide rails 10 and the like, and the player penetrates the glass area 6 through the glass plate 6 of the glass door 5. Visually visible. When the player rotates the launch handle 9, the launch device 12 provided at the lower portion of the front frame 2 continuously launches the game balls stored in the tray 7 toward the game area 11. ing. Near the center of the game area 11, a center accessory device 13 is disposed, and a start winning opening 14 is provided immediately below the center accessory device 13. As will be described in detail later, the center accessory device 13 includes a frame-like case 15 having a rectangular opening 15a and an effect display device 16 disposed on the back side of the frame-like case 15 and exposed from the opening 15a. Have. The effect display device 16 displays the result of the electronic lottery related to the special symbol performed when the game ball wins the winning prize opening 14 in a predetermined effect mode. In the case of the present embodiment, LCD (liquid crystal display) is used.

  An attacker device 17 is provided immediately below the start winning port 14, and a plurality of (for example, four) general winning ports 18 are provided around the start winning port 14 and the attacker device 17. The attacker device 17 is a device that is opened a predetermined number of times when the game ball wins and shifts to the jackpot gaming state as a result of the electronic lottery related to the special symbol performed when the game ball wins the start winning opening 14. . When the attacker device 17 is opened, a large winning opening (not shown) is exposed, so that a game ball can win and obtain many prize balls. Further, when the game balls win the general winning opening 18, a predetermined number of game balls are paid out as prize balls. The game balls that have not entered the start winning port 14 or the general winning port 18 are collected from an out port 19 provided at the lowermost position of the game area 11. Although omitted in FIG. 2, game nails and windmills are provided in the game area 11, and the game balls flow down in the game area 11 while changing irregularly by these game nails and windmills. It will be followed.

  As shown in FIG. 3, the frame-like case 15 of the center accessory device 13 includes an upper stage 20 that extends in the left-right direction along the lower side of the opening 15 a and a lower stage 21 that extends in the left-right direction below the upper stage 20. The left ends of the upper stage 20 and the lower stage 21 form a branch stage 22. A guide hole 20 a is formed at the center of the upper stage 20, and the guide hole 20 a communicates with a lead-out hole 23 formed directly above the start winning opening 14. Thus, when a game ball rolling on the upper stage 20 enters the guide hole 20a and falls from the lead-out hole 23, the game ball can be won at the start winning opening 14 with a very high probability. On the other hand, a guide groove 21 a is formed at the center of the lower stage 21, and this guide groove 21 a is formed at a position directly above the lead-out hole 23. As a result, when the game ball rolling on the lower stage 21 falls from the guide groove 21a, the game ball can be won at the start winning opening 14 with a relatively high probability.

  A hollow warp passage 24 is provided on the left side wall of the frame-like case 15, and an inlet 24a of the warp passage 24 opens toward the game area 11, but an outlet 24b of the warp passage 24 is a branch stage. Opening toward 22. Therefore, when a game ball flowing down the game area 11 on the left side of the center accessory device 13 enters the inlet 24a of the warp passage 24, the game ball passes through the warp passage 24 and is discharged from the outlet 24b to the branch stage 22. Is done. A movable accessory 25 simulating a person is disposed on the right side wall of the frame-shaped case 15, and a movable accessory 26 simulating a telephone is disposed on the upper side wall of the frame-shaped case 15. The movable combination objects 25 and 26 are operated by a driving mechanism (not shown) using a motor, a solenoid, or the like as a drive source, and the lottery result of the electronic lottery related to the special symbol described above depends on the movable mode of the movable combination objects 25 and 26. Has come to be suggested.

  As shown in FIG. 4, a partition wall 27 is disposed near the center of the branch stage 22, and the branch stage 22 is partitioned into a first region S <b> 1 and a second region S <b> 2 by the partition wall 27. The first area S1 is a front-stage area facing the outlet 24b of the warp passage 24, and the left end of the upper stage 20 communicates with the first area S1. A movable body 28 is disposed in the first region S1, and this movable body 28 is pivotally supported by the frame-like case 15 with a communicating portion with the upper stage 20 as a fulcrum. The second region S2 is a rear-side region facing the first region S1 through the partition wall 27, and the left end of the lower stage 21 communicates with the second region S2. A portion of the branch stage 22 corresponding to the second region S2 is inclined forward and downward toward the lower stage 21, and a partition wall 29 is provided upright at a corner portion of the second region S2. The partition wall 29 prevents the game ball from jumping out from the second region S2 to the game region 11, and synthetic resin can be used as the material thereof. However, the partition wall 29 on the side facing the partition wall 27 is not provided. Forming with an elastic material such as rubber is preferable because it can absorb the momentum of the game ball jumping into the second region S2 and hitting the partition wall 29.

  The partition wall 27 is a triangular prism-shaped plate member, and the partition wall 27 is moved up and down in a vertical direction by a drive mechanism described later so as to enter and exit from the branch stage 22. As shown in FIG. 5, a plurality of hemispherical convex portions 27a are provided on the wall surface of the partition wall 27 on the side facing the outlet 24b of the warp passage 24, and the entire partition wall 27 or only the convex portions 27a are provided. It is formed using an elastic material such as rubber. Thereby, when the game ball discharged from the outlet 24b of the warp passage 24 toward the first region S1 hits the partition wall 27 protruding on the branch stage 22, the momentum of the game ball is absorbed by the elasticity of the convex portion 27a. It has come to be. As shown in FIG. 6, a shaft-like body 30 is suspended from the lower surface of the partition wall 27, and an L-shaped drive part 30 a is formed on the shaft-like body 30. A rack 30b is formed on the lower side surface of the shaft-shaped body 30, and a pinion 31 is engaged with the rack 30b. The pinion 31 is fixed to the rotary shaft 32a of the motor 32. When the motor 32 is rotated in both forward and reverse directions, the rotational motion is converted into the vertical motion of the shaft-like body 30 via the meshing portion of the pinion 31 and the rack 30b. Thus, the partition wall 27 moves up and down in the vertical direction so as to enter and exit the branch stage 22. That is, the drive mechanism mentioned above is comprised by the shaft-shaped body 30 which has these motor 32, the pinion 31, and the rack 30b.

  The movable body 28 is a plate-like member having a triangular cross section with the upper surface as an inclined guide portion 28a. Shaft portions 28b project from both side walls of the movable body 28 near the upper stage 20. These shaft portions 28 b are rotatably supported by the frame-like case 15, and the movable body 28 swings and rotates around the shaft portion 28 b as the partition wall 27 moves up and down. That is, as shown in FIG. 6A, when the partition wall 27 is lowered to the lowest position that is substantially flush with the branch stage 22, the drive unit 30 a of the shaft-like body 30 is moved from the lower surface of the movable body 28. A large gap G is ensured between the upper end of the drive unit 30a and the lower surface of the movable body 28. In this case, the movable body 28 is stopped at a position where it comes into contact with a stopper (not shown) of the frame-like case 15 by its own weight, and the inclined guide portion 28a on the upper surface of the movable body 28 and the branch stage 22 are substantially flush with each other. . Therefore, when the game ball is discharged from the outlet 24b of the warp passage 24 toward the first region S1 in this state, the game ball rolls on the inclined guide portion 28a of the movable body 28, and then the partition wall 27 is moved. It will pass through and jump into the second region S2.

  When the motor 32 rotates clockwise in the state shown in FIG. 6A, the pinion 31 meshing with the rack 30b rotates in the same direction, so that the partition wall 27 and the shaft-like body 30 rise integrally in the arrow Y1 direction. As a result, the gap G gradually decreases. Then, as shown in FIG. 6B, when the partition wall 27 protrudes from the branch stage 22 by a predetermined amount, the upper end of the drive unit 30a comes into contact with the lower surface of the movable body 28, so that the gap G is the minimum zero. It becomes. Further, when the motor 32 continues to rotate clockwise, the free end side of the movable body 28 is lifted by the drive unit 30a, so that the movable body 28 begins to swing and rotate clockwise about the shaft portion 28b. Then, as shown in FIG. 6C, when the motor 32 stops when the amount of projection of the partition wall 27 from the branch stage 22 reaches the maximum, the tilt guide portion 28a of the movable body 28 tilts with respect to the branch stage 22. The angle is also maximized. That is, if the stroke from FIG. 6A to FIG. 6C is the forward stroke, the partition wall 27 continues to rise from the beginning to the end of the forward stroke, but the movable body 28 is between the middle and the last of the forward stroke. The partition wall 27 and the movable body 28 are moved upward with a time difference within the forward path.

  On the contrary, when the motor 32 rotates counterclockwise in the state shown in FIG. 6C, the pinion 31 meshing with the rack 30b rotates in the same direction, so that the partition wall 27 and the shaft-shaped body 30 are moved to the arrow Y2. The movable body 28 begins to descend integrally in the direction, and accordingly, the movable body 28 also starts to swing and rotate in the counterclockwise direction in FIG. Then, as shown in FIG. 6B, after the movable body 28 comes into contact with the stopper and stops, and the inclined guide portion 28a and the branch stage 22 are substantially flush, the partition wall 27 and the shaft-shaped body When 30 further descends in the Y2 direction, the upper end of the driving unit 30a moves away from the lower surface of the movable body 28, and the gap G gradually increases accordingly. Then, as shown in FIG. 6A, when the motor 32 stops when the gap G reaches the maximum, the partition wall 27 descends to the lowest position that is substantially flush with the branch stage 22, and thereafter the motor When 32 repeats the clockwise and counterclockwise rotations, the partition wall 27 and the movable body 28 move up and down with a time difference. That is, if the stroke from FIG. 6 (c) to FIG. 6 (a) is the return stroke, the partition wall 27 continues to descend from the beginning to the end of the return stroke, but the movable body 28 moves from the beginning to the middle of the outbound stroke. The partition wall 27 and the movable body 28 are moved downward with a time difference in the return path.

  In the pachinko machine P according to the present embodiment configured as described above, when a game ball that is launched from the launching device 12 and flows down the game area 11 enters the entrance 24a of the warp passage 24, the game ball is sent to the warp passage 24. Is discharged from the outlet 24b to the branch stage 22. Here, a partition wall 27 that repeats an ascending operation and a descending operation is arranged near the center of the branch stage 22, and the branch stage 22 is partitioned into a first region S 1 and a second region S 2 by the partition wall 27. Therefore, the game balls discharged from the outlet 24b of the warp passage 24 are first distributed to one of the first region S1 and the second region S2 on the branch stage 22 according to the up and down state of the partition wall 27.

  That is, as shown in FIG. 6A, when the partition wall 27 is lowered to the lowest position that is substantially flush with the branch stage 22, the amount of protrusion of the partition wall 27 from the branch stage 22 is relatively small. When the number of the game balls is small, the game ball discharged from the outlet 24b of the warp passage 24 to the branch stage 22 passes through the first region S1 and the partition wall 27, jumps into the second region S2, hits the partition wall 29, and then the second region. The direction is changed in S2 and rolls on the lower stage 21. Of the game balls that roll on the lower stage 21, the game balls that have fallen from the guide groove 21 a will win the start winning opening 14 with a high probability, and other game balls will be placed on the lower stage 21. It is discharged from the front edge to the game area 11.

  On the other hand, as shown in FIG. 6C, when the partition wall 27 protrudes from the branch stage 22 to the maximum, or when the amount of protrusion of the partition wall 27 from the branch stage 22 is relatively large, the exit of the warp passage 24 The game balls discharged from the branch stage 22 to the branch stage 22 pass through the first region S1 and hit the partition wall 27, and then the direction is changed by the inclined guide portion 28a of the movable body 28 arranged in the first region S1. Roll on the upper stage 20. At that time, the partition wall 27 and the movable body 28 move up and down with a time difference. For example, when a game ball hits the partition wall 27 with the inclined guide portion 28a of the movable body 28 in a substantially horizontal posture, this game After the sphere is temporarily retained on the inclined guide portion 28a of the movable body 28, the initial speed is reached from the movable body 28 when the inclination angle of the inclined guide portion 28a increases with the swinging rotation of the movable body 28. It is discharged in a zero state and rolls on the upper stage 20. Further, when the game ball hits the partition wall 27 with the tilt guide portion 28a of the movable body 28 tilted to the maximum with respect to the branch stage 22 or with a relatively large tilt angle, the game ball is movable. It is discharged at different initial speeds according to the inclination angle of the body 28 and rolls on the upper stage 20. Of the game balls discharged from the movable body 28 toward the upper stage 20 as described above, a game ball having a high initial speed passes through the guide hole 20a through the lead-out hole 23 and wins the start winning opening 14 with a very high probability. The game ball having a low initial velocity falls from the front edge portion of the upper stage 20 to the lower stage 21 and is discharged to the game area 11.

  As described above, in the pachinko machine P according to the present embodiment, the game balls discharged from the outlet 24b of the warp passage 24 to the branch stage 22 are moved to the upper stage 20 and the lower stage 21 according to the lifted state of the partition wall 27. In addition, the initial speed toward the upper stage 20 can be changed according to the inclination angle of the movable body 28 that moves up and down with a time difference from the partition wall 27. The behavior of the game ball discharged to the branch stage 22 is not uniform, which can enhance the interest of the game.

  Further, in the pachinko machine P according to the present embodiment example, shaft portions 28b are projected from both side walls of the movable body 28 near the upper stage 20, and these shaft portions 28b are supported on the frame-like case 15 so as to be swingable. A drive unit 30a is provided on the shaft-like body 30 that hangs down from the partition wall 27 so as to face the lower surface of the movable body 28 so as to be able to come into contact with and separate from the lower surface of the movable body 28. Since the drive mechanism that converts the lifting and lowering operation of the shaped body 30 is employed, the partition wall 27 and the movable body 28 can be moved up and down with a time difference from each other using one motor 32 as a drive source.

  In the embodiment described above, the upper stage 20 and the lower stage 21 having a two-stage structure are provided in the frame-shaped case 15, and the first area S1 and the second area S2 partitioned by the partition wall 27 are the first ones. The region S1 communicates with the upper stage 20 and the second region S2 communicates with the lower stage 21, but it is also possible to adopt a single stage structure having only one stage. In this case, if the first area S1 communicates with the stage, and the second area S2 communicates with a path different from the stage, and this path is opened toward the game area 11, it passes through the partition wall 27. Then, the game balls distributed to the second area S2 are discharged to the game area 11 through this passage.
