The stage guide tube 40 opens toward the side of the display frame 30, extends downward while curving along the inner surface of the left side of the display frame 30, and toward the center of the stage 42 at the left end of the stage 42. Open.

  In the pachinko gaming machine 10 of the present embodiment, as described above, the display device 101 having the liquid crystal screen 102 larger than the conventional one is used, and the liquid crystal screen 102 occupies about half of the game area R1, and the rest. In the limited space, the other than the display device 101 (wind turbine 110, start gate 18, winning ports 14A, 14B, 15, 20, etc.) are arranged so as not to hinder the game. In such an accessory arrangement in the pachinko gaming machine 10 of the present embodiment, a liquid crystal screen is used as a guide path for stably guiding the game ball flowing down the left side of the display device 101 to the first start winning opening 14A. It is difficult to provide it so that it does not overlap with 102 at all, and at least a part of the guide path must be arranged so as to cross the lower left corner R2 of the liquid crystal screen 102. Here, the guide path for guiding the game ball is normally formed by hitting a plurality of obstacle nails 142 in a row on the game board 11 as shown in FIG. When the road crosses the lower left corner R2 of the liquid crystal screen 102, the lower left corner R2 of the liquid crystal screen 102 must be covered with a game board in order to hit the obstacle nail. Then, the significance of using the large liquid crystal screen 102 is diminished, and there is a possibility that a part of the display image is missing from the player. Therefore, in the pachinko gaming machine 10 of the present embodiment, a portion of the guide path that crosses the display screen 102 is configured by a resin ball guide wall 120 that is integrally formed with the display frame 30, and the display screen 102 The front surface need not be covered with the game board 11. Thus, the game ball can be guided from the left side of the display device 101 to the first start winning opening 14A while keeping the area covered from the front side of the display screen 102 as small as possible.

  Specifically, the sphere guide wall 120 (corresponding to the “guidance member” of the present invention) is provided at the lower end of the left side of the display frame 30, and the lower left corner R 2 of the display screen 102. It crosses the front diagonally. The spherical guide wall 120 protrudes forward from the front surface of the display frame 30 and is disposed in front of the stage 42. As shown in FIG. 5, the ball guide wall 120 extends substantially horizontally from a position directly below the rotating shaft 110A of the windmill 110 toward the center of the game area R1 and gently downwards toward the first start winning opening 14A. Inclined. The sphere guide wall 120 is slightly bent at the center, and the left half of the sphere guide wall 120 has a gentler slope than the right half. If the sphere guide wall 120 is made of a transparent member, the visibility of the display screen 102 will not be impaired even if the sphere guide wall 120 is disposed so as to overlap the front side of the display screen 102.

  The upper surface of the ball guide wall 120 is a guide path 121 on which a game ball can roll. α3 (about 15 degrees in the present embodiment) is equal to or less than an angle β (about 27 degrees in the present embodiment) with respect to the horizontal direction of a ball guide nail row 140 described later. In this way, by making the gradient of the guide path 121 gentler than the gradient of the ball guide nail row 140, the height of the guide path 121 in the vertical direction can be reduced. The range where the road 121 overlaps in the front-rear direction can be made as small as possible. The guide path 121 has a width that allows only one game ball to pass therethrough and is configured by two planes having different gradients. For example, the first guide path 121A formed in the left half of the sphere guide wall 120 has an angle α1 with respect to the horizontal direction of about 5 degrees, whereas the second guide formed in the right half of the sphere guide wall 120 is In the path 121B, the angle α2 with respect to the horizontal direction is about 20 degrees. That is, the gradient of the second guide path 121B is larger than the first guide path 121A. A stepped portion 121C is provided between the respective guideways 121A and 121B, and the gradient of the guideway 121 changes with the stepped portion 121C as a boundary.

  At the left end portion of the sphere guide wall 120, a roll-out prevention wall 122 projects upward. The right side surface of the turnout prevention wall 122 is an inclined surface 122A, and the inclined surface 122A can cause a game ball that has fallen directly below the windmill 110 to roll to the right side, that is, the second guide path 121B side. it can. In addition, a game ball that has rolled toward the turnout prevention wall 122 so as to climb the first guide path 121A due to a collision between game balls or the like abuts against the inclined surface 122A of the turnout prevention wall 122 and the rolling direction is reversed. And it comes to roll toward the 2nd guide way 121B side. That is, the anti-roll-out wall 122 prevents the game ball that has fallen on the ball guide wall 120 from falling from the left end of the ball guide wall 120.

  As shown in FIG. 4, a front cover body 150 is provided on the front side of the sphere guide wall 120. The front cover body 150 is provided so as to overlap the front surface of the game board 11, covers the front side of the ball guide wall 120, and partially covers the lower left corner of the display screen 102. In addition, a space having the same width as that of the guide path 121, that is, a space through which only one game ball can pass is formed between the front cover body 150 and the front surface of the display frame body 30. The game balls rolling on the ball guiding wall 120 by the front cover body 150 are prevented from jumping forward in the middle. In addition, since the front cover body 150 is formed of, for example, a transparent resin member, the player can visually recognize the rolling situation of the game ball on the ball guide wall 120 through the front cover body 150 and A display image can also be visually recognized.

  As shown in FIG. 5, a ball guide nail row 140 in which a plurality of obstacle nails are arranged in a row between the right end portion of the ball guide wall 120 and the first start winning opening 14A (the “nail row of the present invention”). ”) Is formed. Specifically, the ball guide nail row 140 is configured to guide a ball nail group 140A in which a plurality of (eg, 3 to 4) obstacle nails are arranged in a row at equal intervals (eg, about 5.5 mm). A plurality of sets (for example, three sets) are arranged side by side on the extension of the wall 120 (guide path 121). Between adjacent obstacle nail groups 140A, there is a gap through which a game ball can pass. Thereby, a part of the game ball rolling on the ball guide nail row 140 toward the first start winning opening 14A reaches the first starting winning opening 14A from the gap below the game area R1. It is designed to flow down. Since the ball guide wall 120 is disposed in front of the liquid crystal screen 102, the ball guide nail row 140 may be disposed only at a position that does not overlap the liquid crystal screen 102, that is, the game board 11.

  Here, the angle β with respect to the horizontal direction of the ball guide nail row 140 is preferably 27 to 30 degrees (for example, about 27 degrees in the present embodiment). The reason is that when the angle β is larger than 30 degrees, the game ball is excessively accelerated in the process of rolling on the ball guide nail row 140 toward the first start winning opening 14A, and the game ball is stabilized to the first. May not be able to be guided to the start winning opening 14A, and if the angle β is smaller than 27 degrees, the momentum of the game balls is insufficient and most of the game balls can reach the first start winning opening 14A. This is because it may disappear.

  By the way, since the game ball gains momentum in the process of flowing down the game area R1, the game ball that has not been sufficiently reduced before reaching the ball guide wall 120 is placed on the ball guide wall 120 as shown in FIG. Or rolls on the ball guiding wall 120 vigorously. In such a case, there is a possibility that the game ball cannot be stably guided toward the first start winning opening 14A. Therefore, the pachinko gaming machine 10 according to the present embodiment includes a pendulum body 130 for depressing the game ball before reaching the ball guide wall 120.

As shown in FIG. 5, the pendulum body 130 is made of, for example, resin, and is provided on the right side of the windmill 110 and directly above the first guide path 121A as shown in FIG. As shown in FIG. 9, the pendulum body 130 is disposed in a space formed between the front cover body 150 and the front surface of the display frame body 30 and faces the windmill 110 in the horizontal direction. The pendulum body 130 has a fan shape, and is pivotally supported by a rotation shaft 130A penetrating a main portion of the fan in the front-rear direction. Both left and right side surfaces of the pendulum body 130 are flat surfaces, and in particular, the left side surface facing the windmill 110 side is a contact flat surface 130B that can contact the game ball. Further, the lower end surface of the pendulum body 130 is an arc surface centered on the rotation shaft 130A. The rotation shaft 130A is horizontally inserted and fixed between the stage guide tube 40 and the cover body 150.

  The pivotable range of the pendulum body 130 is restricted by a pair of rotation restricting protrusions 130 </ b> C and 130 </ b> C (corresponding to the “turn restricting member” of the present invention) protruding from the rear surface of the front cover body 150. As shown in FIG. 5, the pendulum body 130 is always stationary in a state where the pendulum body 130 is in contact with one rotation restricting protrusion 130 </ b> C. When the game ball comes into contact with the pendulum body 130, the pendulum body 130 rotates counterclockwise in FIG. 5 around the rotation shaft 130A, and the speed of the contacted game ball is more accurate. The horizontal velocity component is reduced. The rotation angle of the pendulum body 130 increases as the horizontal velocity component of the game ball that abuts the pendulum body 130 increases, and abuts against the other rotation restricting protrusion 130C (a state indicated by a broken line in FIG. 5). It can be turned up to. Even in the state where the rotation angle of the pendulum body 130 is maximized (the state where the pendulum body 130 is in contact with the other rotation regulating protrusion 130C), the contact flat surface 130B faces the first guide path 121A side. Therefore, the game ball that has come into contact with the pendulum body 130 can be reliably dropped onto the first guide path 121A.

  Further, the narrowest interval L1 between the pendulum body 130 and the projecting piece 110B of the windmill 110 is not less than the diameter of the game ball (about 11 mm) and less than twice the diameter of the game ball (for example, the diameter of the game ball). It is configured to be about 1.5 times the above. Thereby, the clogging of the ball | bowl between the protrusion 110B of the windmill 110 and the pendulum body 130 can be prevented. Further, the interval L2 of the narrowest portion between the pendulum body 130 and the first guide path 121A is not less than the diameter of the game ball and less than twice the diameter of the game ball (for example, approximately 1.3 times the diameter of the game ball). ). Thereby, the game ball rolling on the first guide path 121A and the pendulum body 130 do not interfere with each other, and the ball clogging between the ball guide wall 120 and the pendulum body 130 can be prevented. Further, the momentum of the game ball rolling on the ball guide wall 120 is not reduced too much.

  By the way, the pendulum body 130 is configured such that the horizontal velocity component of the abutting game ball is reduced to 0 to 1/2 before the abutment. Specifically, the pendulum body 130 is configured to have a predetermined mass so that the velocity component in the horizontal direction of the game ball is reduced. The mass of the pendulum body 130 can be calculated based on, for example, the momentum conservation law.

That is, the mass of the pendulum body 130 is M, the mass of the game ball is m, the horizontal velocity component before the collision of the game ball is VH1, the horizontal velocity component after the collision of the game ball is VH2, and the mass of the pendulum body 130 Where M is the angular velocity of the pendulum body 130 after the game ball collides, ω is the distance from the pivot shaft 130A to the center of gravity of the pendulum body 130, and e is the rebound coefficient of the game ball and the pendulum body 130.
m · VH1 = m · VH2 + M · R · ω (6)
VH2-R · ω = −e (VH1-0) (7)
The above relational expressions (6) and (7) are established. From these relational expressions (6) and (7),
VH2 = (me · M) · VH1 / (m + M) (8)
The relational expression (8) is established.

By the way, when the horizontal velocity component VH2 of the game ball in contact with the pendulum body 130 is reduced to 0 to 1/2 of the horizontal velocity component VH1 of the game ball before contacting the pendulum body 130, that is,
0 ≦ VH2 ≦ (1/2) · VH1 (9)
When the above relational expression (9) holds, from the above relational expressions (8) and (9),
m / (1 + 2e) ≦ M ≦ m / e (10)
The relational expression (10) is established.

  Here, for example, when the mass m of the game ball is 5 [g] and the rebound coefficient e between the game ball and the pendulum body 130 is 0.4, from the relational expression (10), the mass M of the pendulum body 130 is If 1.7 [g] ≦ M ≦ 12.5 [g], the horizontal velocity component of the game ball after contact can be reduced to 0 to 1/2 before contact. In the present embodiment, for example, 3 [g] is set so that the mass M of the pendulum body 130 is included in this numerical range. Note that the mass of the pendulum body 130 may be set based on the law of conservation of mechanical energy in addition to the above-described relational expressions (6) to (10), or the horizontal velocity of the game ball You may set based on the measurement result of the mass of a component and the pendulum body 130. FIG. The pendulum body 130 has a hollow interior, and a removable weight is accommodated therein. By changing the weight of the weight, the reduction rate of the horizontal velocity component of the game ball before and after contact can be changed. You may do it.

Next, the operation and effect of this embodiment configured as described above will be described.
When the player turns the operation knob 28, the game ball is launched clockwise along the guide rail 12 from the lower end of the game area R1. Then, as shown in FIG. 8, a part of the game balls driven into the game area R1 can pass exactly one game ball formed between the right side of the display frame 30 and the guide rail 12. It flows down through the gap, and most of the remaining game balls collide with the upper side of the display frame 30 and flow down the left side of the display frame 30. The game ball flowing down along the right side of the display frame 30 falls on the flow dividing wall 31A (see FIG. 4), and flows down separately from here to the left. The game ball that has flowed down from the right end of the flow dividing wall 31 </ b> A is guided by the guide rail 12 and enters the out port 16. On the other hand, the game ball that has flowed down from the left end due to the inclination of the flow dividing wall 31A is guided by the obstacle nail and flows down obliquely downward toward the second start winning port 14B. In this manner, the game ball that has flowed down through the right side of the display frame 30 does not flow down toward the first start winning opening 14A.

  On the other hand, a part of the game ball that has dropped to the upper side of the display frame 30 and flowed along the left side passes through the start gate 18 while flowing down the left side of the display frame 30. In addition, a part of the game balls is guided to the display frame body 30 side by the obstacle nail, passes through the stage guide tube 40, enters the display frame body 30, and is discharged to the left end portion of the stage 42.

  The game ball transferred to the stage 42 reciprocates left and right on the stage 42. In the process of reciprocating left and right, the game balls gradually lose their momentum, and most of the game balls fall below the stage 42 (display frame 30) from the gentle slope 43B formed on the left and right sides of the stage 42. Some of these game balls are guided by the obstacle nail and win the first or second start winning opening 14A, 14B or the big winning opening 15, and other game balls enter the out opening 16 without winning. Also, as shown in FIG. 8, some of the game balls that roll on the stage 42 move into the warp path 45 from the raised portion 43A, and are discharged from the ball outlet 46B through the warp path 45. Almost all the game balls discharged from the ball outlet 46B pass between the obstacle nails 141 and 141 and win the first start winning opening 14A. As a result, when the game ball is discharged from the ball outlet 46B, the player gazes at the game ball while expecting to win the first start winning opening 14A.

  When the game ball flowing down the left side of the display frame 30 comes into contact with the windmill 110, the windmill 110 rotates. The flow direction of the game ball is distributed to the left and right direction of the windmill 110 according to the rotation direction at this time. Specifically, as shown in FIG. 8, when the windmill 110 that has received the game ball by the projecting piece 110 </ b> B rotates counterclockwise, the game ball is distributed to the left side of the windmill 110. On the other hand, when the windmill 110 receiving the game ball by the projecting piece 110B rotates in the clockwise direction, the game ball is distributed to the right side of the windmill 110 and flows down toward the ball guide wall 120 as shown in FIG. At this time, the game ball directed toward the ball guiding wall 120 falls directly on the ball guiding wall 120 or jumps to the right side by colliding with the windmill 110 as shown in FIG. Abut.

  As shown in FIG. 10, among the game balls that have dropped directly onto the ball guide wall 120, the game balls that have been sufficiently depressurized by coming into contact with the windmill 110 are placed on the ball guide wall 120 as they are. Roll towards. On the other hand, the game ball that has not been sufficiently reduced may bounce off the ball guide wall 120, but the game ball is returned to the ball guide wall 120 by contacting the pendulum body 130, and the ball on the ball guide wall 120. To the ball guide nail row 140.

  A game ball that rolls on the ball guide wall 120 rolls in the order of the first ball guide path 121A and the second guide path 121B having different gradients, and the ball guide nail train having a steep gradient from the left end of the ball guide wall 120. Transfer to 140 and roll toward the first start winning opening 14A. As shown in FIG. 8, some of the game balls rolling on the ball guide nail row 140 fall downward from the gap between the adjacent obstacle nail groups 140A in the process toward the first start winning opening 14A. The game ball that has reached the end of the ball guide nail row 140 without dropping from the gap wins the first start winning opening 14A or the opened second start winning opening 14B.

  As shown in FIG. 11, when the game ball abuts against the windmill 110 and is bounced in the horizontal direction and abuts against the abutment flat surface 130B of the pendulum body 130, the pendulum body 130 is counterclockwise about the rotation shaft 130A. Rotate around. Then, the horizontal velocity component of the game ball is absorbed, and the game ball is de-energized. Specifically, the horizontal velocity component of the game ball after contacting the pendulum body 130 is reduced to 0 to 1/2 before contacting the pendulum body 130.

  Then, the game ball in contact with the pendulum body 130 falls on the ball guide wall 120 (more precisely, the first guide path 121A) in a state where the velocity component in the horizontal direction is reduced, and on the ball guide wall 120 Is moved toward the ball guide nail row 140, and further transferred from the ball guide wall 120 to the ball guide nail row 140 and rolled toward the first start winning opening 14A.

  In addition, when two game balls flow down to the ball guide wall 120 at the same time, they may collide and one game ball may roll toward the left end of the ball guide wall 120. Since it is returned without getting over the prevention wall 122, the game ball does not fall from the left end of the ball guiding wall 120. That is, all the game balls that have fallen on the ball guiding wall 120 can be rolled toward the first start winning opening 14A.

  As described above, according to the pachinko gaming machine 10 of the present embodiment, a part of the game ball that has flowed down the left side of the display device 101 falls on the ball guide wall 120 after being abutted against the windmill 110 and depressed. . At this time, the game ball that is not sufficiently de-energized by the windmill 110 and is relatively large-played to the right in the horizontal direction comes into contact with the pendulum body 130. The game ball in contact with the pendulum body 130 falls on the ball guiding wall 120 after the horizontal speed component is reduced to 0 to 1/2 before the contact by the rotation of the pendulum body 130. In this way, the reduced game ball is a ball that extends in the horizontal direction and is gently inclined toward the first start winning opening 14A (specifically, an angle β or less with respect to the horizontal direction of the ball guide nail row 140). Since it flows down to the first start winning opening 14A side through the guide wall 120, the game ball can be stably guided to the first starting winning opening 14A without excessive acceleration. In addition, since the gradient of the ball guide nail row 140 provided on the extension of the ball guide wall 120 is made relatively gentle with 27 to 30 degrees, the game ball can be guided more stably to the first start winning opening 14A. Can do. Thereby, the expectation that the game ball flowing down the side of the display device 101 wins the first start winning opening 14A can be increased. Further, since the game ball stably flows down from the guide path 121 to the start winning opening 14A first, the winning rate to the first starting winning opening 14A can be adjusted.
