In a pachinko machine with
The ball path switching mechanism is
A motor that is installed on the back side of the game board and that is switched and controlled in accordance with the right generation presence / absence condition, a rack gear that can move in a meshing manner with a pinion coupled to an output shaft of the motor, and the game A support member that is fixedly inserted in the front-rear direction of the board and has a long-hole-shaped guide hole with a fixed width formed in a penetrating manner, and the support member is inserted in the front-rear direction of the guide hole so that it cannot rotate about the axis. A transmission rod supported in a state and connected to the rack gear and capable of moving back and forth in the left-right direction along the rail surface of the game area, and connected to the front end of the transmission rod on the inner peripheral surface side of the rail surface A first situation that is arranged above the right exercise opening and facilitates the winning of a game ball to the right exercise opening; and a second situation that prevents the winning of the game ball into the right exercise opening. Appear by movements corresponding to occurrence and loss of rights And a harm member,
The obstacle member is formed in an approximately triangular trapezoidal shape by an elastic body, and a game ball that has entered the game area and collided with the obstacle member based on the flight trajectory is incident on the lower surface of the obstacle member at the time of the collision. A ball contact surface that rebounds in a regular rebound state in a reflex angle direction opposite to the angle is formed on a flat inclined surface inclined at an acute angle with respect to the upper end of the longitudinal center of the game area. Always in a downwardly inclined ball contact posture in the game area 2, and can be moved in the left-right direction in the game area together with the transmission rod via the pinion and rack gear by the drive control of the motor,
The obstacle member displaces the ball contact surface to the first rebound position as the first situation in which the game ball falls down through the ball flow path where the game ball easily wins the right exercise opening when the right is generated. Then, before the right is generated and when the right is lost, the ball contact surface is displaced to a second rebound position as the second situation in which the game ball falls through the ball flow path that bypasses the right exercise opening. The configuration is set as described above .
[0006]
[Action]
In the invention of claim 1, when the winning ball passes through the right generation area and the right is generated, the first situation for facilitating the dropping of the game ball into the right-exercising port appears due to the movement of the obstacle member, When is lost, a second situation that prevents the game ball from entering the right-exercising port appears due to the movement of the obstacle member, and the ball path of the game ball in the game area is switched.
[0007]
Further, in the invention of claim 1 , the ball contact surface of the obstacle member is displaced to the first rebound position where the game ball is easily guided to the right strike port and the second rebound position where it is difficult to guide the game ball to the right strike port. The game ball collides with the ball contact surface at the first rebound position or the second rebound position and is rebounded in a regular rebound state.
[0008]
【The invention's effect】
According to the invention of claim 1, the probability of winning the right exercising opening when the right is generated can be easily switched by the movement of the obstacle member, and the probability of winning the right exercising opening is adjusted by adjusting the nail around the right exercising opening. It is not necessary to change the number of steps, and it is possible to prevent aiming at which the game balls are intensively driven toward the right-of-exercise port without the right being generated.
[0009]
According to the first aspect of the present invention, the game ball can easily win a right-exercise port by simply displacing the ball contact surface of the obstacle member, and the game ball can hardly win a right-exercise port. The ball path switching mechanism can be simplified by simplifying the ball path switching mechanism, and the rebound range of the game ball is stabilized by stabilizing the rebound state where the game ball hits the ball contact surface. Can be limited within a certain range, and the game ball can be irregularly rebounded and diffused in each direction, thereby eliminating the problem of uncertain switching of the ball path.
[0010]
【Example】
Next, a first embodiment of the present invention will be described with reference to FIGS.
In the game board 1 of the pachinko machine, a special winning opening 3a that can be controlled to open and close, a symbol display body 3b that variably displays a symbol, and a winning ball that has won a prize in the specific winning opening 3a are provided at the center of the game area 2 of the gaming board surface. The rotating body 3c to be distributed, the right generation area 3d in which a special device is operated to generate a right when a winning ball won in the specific winning opening 3a passes, and a variable winning that causes a situation that gives a special profit to the player A variable insertion device 3 having a mouth 3e is installed.
[0011]
On both sides of the lower end of the variable winning device 3, a pair of left and right gates 4 for starting a symbol change by the symbol display body 3b when a game ball passes are installed.
[0012]
On the right side of the upper portion of the variable winning device 3, a rotating body 5a that is driven to rotate clockwise when the power of the pachinko machine is turned on, and a winning ball that has dropped into the specific winning opening 3a pass through the right generating area 3d to generate a right. A start winning device 5 having a right exercise opening 5b for opening a variable winning opening 3e and exercising the right when a game ball falls in the state is installed.
[0013]
Above the starting prize-winning device 5, a group of nails are arranged in a left-right symmetrical manner in a circular arc shape, and a pair of left and right nails at the upper end are placed across a ball passage 18 directly above the right exercise opening 5b. The first nail row 16 and a group of nails are arranged so as to be inclined downwardly to the left above the first nail rows 16, and the lower nails are the upper nails of the first nail rows 16. And a second nail row 17 which is opposed to each other with a ball opening 19 interposed therebetween.
[0014]
A third nail row in which a group of nails is arranged at an upper portion of the upper right rail surface 20 that divides the game area 2 above the starting prize-winning device 5 is inclined at the upper portion and inclined downward at the lower portion to the left. 21, a fourth nail row 22 arranged adjacent to the lower side of the third nail row 21 and arranged so that a group of nails are inclined upwardly to the left, and a group of nails is a third nail row A fifth nail row 23 arranged on the left side of 21 is installed.
[0015]
When the game ball that has been thrown into the game area 2 passes through the gate 4 and a passing ball is detected, the symbol display body 3b starts to display the variation of the symbol. The symbol display body 3b stops the symbol variation display and identifies the symbol.
[0016]
When the specific symbol at the time of stopping the variable display of symbols is one of 1, 3, 5, 7, and 9, and the winning symbol is a winning symbol, the specific winning opening 3a is opened for about 0.75 seconds.
[0017]
When the game ball drops into the open specific winning opening 3a, and the winning ball falls onto the rotating body 3c and passes through the right generation area 3d, the special device is activated and the right is generated. Winning 5b is valid.
[0018]
If the game ball falls into the right exercise slot 5b during the generation of the right, the variable prize opening 3e is opened for about 10 seconds, and a situation in which a special profit is given to the player appears.
[0019]
When 16 game balls drop into the right exercise slot 5b during the generation of the right, or when the winning ball passes through the right generation area 3d again, the operation of the special device is stopped and the generated right disappears. .
[0020]
A right is generated in the upper right corner of the game area 2 above the starting prize-winning device 5 in a first situation that makes it easy to win the right exercise slot 5b and a second situation that prevents winning in the right exercise slot 5b. And a ball path switching mechanism 7 for switching the ball path of the game ball in the game area 2 between a ball path advantageous to the player and a ball path unfavorable to the player. Is installed.
[0021]
The obstruction member 8 includes a main body portion 8a formed in an approximately triangular trapezoidal shape by an elastic body (rubber), and a holder 8b to which the main body portion 8a is coupled, and the inner surface of the main body portion 8a rises inward. A flat ball contact surface 9 is formed, which has a shape that is slanted and repels the game ball that has been driven into the upper right end of the game area 2 and collided with the obstacle member 8 in a regular rebound state.
As specifically shown in FIGS. 1 and 2, the ball contact surface 9 is inclined to an acute angle with a leading edge and wider than the diameter of the game ball when viewed from the upper end of the longitudinal center of the game area 2. (A little more than twice in FIG. 2) It has a flat inclined surface, and is always held in a ball contact posture inclined downward in the game area 2 and is driven into the upper right end portion in the game area 2 The ball hitting surface is used for repelling the game ball that has collided with the ball 9 in a regular rebound state in the direction of the reflective angle opposite to the incident angle at the time of the collision.
[0022]
The obstacle member 8 is disposed in the game area 2 in the vicinity of the third nail row 21 and the upper right rail surface 20 and above the right exercise opening 5b.
[0023]
The transmission rod 10 coupled to the holder 8 b of the obstacle member 8 is installed on the back side of the game board 1 and is connected to the rack gear 11 curved in an arc along the upper right rail surface 20.
[0024]
The support member 12 attached to the game board 1 so as to face the obstacle member 8 is penetrated by a guide hole 12a through which the transmission rod 10 is slidably inserted in a long hole curved in an arc shape along the upper right rail surface 20. The obstacle member 8 is supported by the support member 12 and the transmission rod 10 so as to be movable in a circular arc in an obliquely upward and inward direction and an obliquely downward and outward direction.
2 and 3, the transmission rod 10 is formed in a rectangular prism shape with a cross section orthogonal to the axial direction, and a guide hole 12 a having a constant width of the support member 12. Thus, it is inserted and supported in the front-rear direction in a non-rotating state, that is, in a state in which it cannot rotate about the axis.
[0025]
The bracket 13 attached to the game board 1 is coupled to a motor 14 that drives the obstacle member 8 to advance and retreat along the upper right rail surface 20. A pinion meshed with the rack gear 11 is connected to the output shaft 14 a of the motor 14. 15 is connected.
[0026]
When a winning ball that has won a prize in the specific winning opening 3a passes the right generation area 3d and a right is generated, the motor 14 is temporarily driven when the passing of the winning ball to the right generation area 3d is detected, and the obstacle member 8 is held in a state where it is retracted to the right of the third nail row 21 and the ball contact surface 9 is displaced to the first rebound position 25 for facilitating winning in the right exercising port 5b.
[0027]
The game ball that has collided with the ball contact surface 9 displaced to the first rebound position 25 is repelled on the right side of the third nail row 21 and enters the ball guide channel to the right exercise port 5b and enters the right exercise port 5b. In the state where the third nail row 21 and the fourth nail row 22 are right and the left nail row 17 is left and the ball passes through the ball passages 19 and 18. The probability of falling into the right exercising port 5b through this is increased.
[0028]
When the obstacle member 8 is in the state of disappearance of the right, it moves to the left of the third nail row 21, and the ball contact surface 9 is displaced to the second rebound position 26 that prevents the game ball from falling into the right exercise opening 5b. Held in.
[0029]
The game ball that has collided with the ball contact surface 9 displaced to the second rebound position 26 is rebounded on the left side of the third nail row 21, and the third nail row 21, the fourth nail row 22, and the first nail row 16 on the left side. There is a small probability that the game ball will fall into the right exercising opening 5b by passing through the left sphere passage and passing through the ball passage bypassing the right exercising opening 5b.
[0030]
Subsequently, the operation and effect of the embodiment having the above-described configuration will be described.
In this example, a variable prize opening 3e for giving a special benefit to the player, a right generation area 3d where a right is generated when the winning ball passes, and a variable prize opening 3e when a game ball is dropped during the generation of the right In the pachinko machine having the right exercising opening 5b, the game zone 2 of the game board 1 has a first situation that makes it easy to win the right exercising opening 5b, and the first situation that prevents winning in the right exercising opening 5b. The obstacle member 8 that makes the situation 2 appear by the movement corresponding to the occurrence of the right and the loss of the right is installed, and the obstacle member 8 is a flat ball rest that repels the game ball colliding with the obstacle member 8 in a regular rebound state. Surface 9 is formed.
[0031]
For this reason, the probability of winning the right exercising port 5b when the right is generated can be easily and accurately switched by the movement of the obstacle member 8, and the winning probability to the right exercising port 5b is adjusted by adjusting the nail around the right exercising port 5b. It is not necessary to change the number of steps, and it is possible to prevent aiming at which game balls are intensively driven toward the right exercising port 5b in a state where no right is generated.
[0032]
In addition, by simply displacing the ball contact surface 9 of the obstacle member 8, it is possible to accurately switch between a state in which the game ball is likely to win the right exercise opening 5b and a state in which the game ball is difficult to win the right exercise opening 5b. The ball path switching mechanism 7 can be simplified to simplify the switching of the ball flow path, and the rebound state of the game ball is stabilized by stabilizing the rebound state in which the game ball hits the ball contact surface 9 The game ball rebounds irregularly and diffuses in each direction, and the problem that the switching of the ball path is uncertain can be solved.
[0033]
Next, the ball path switching mechanism of the second embodiment of the present invention shown in FIG. 4 and FIG. 5 will be described. In this example, the right generation port 5b of the start winning device 5 corresponds to the right generation and the right loss. Then, the first situation that makes it easy to drop the game ball into the right exercising port 5b by evacuating and moving out of the game area 2 and into the game area 2, and the falling of the game ball into the right exercising port 5b An obstacle member 8A that causes the second situation to be disturbed appears.
[0034]
The obstacle member 8A is formed in a substantially curved substantially flat plate shape and is installed horizontally. A spherical contact surface 9A is formed on the upper surface of the obstacle member 8A, and the rear end of the obstacle member 8A extends rearward. Then, the transmission rod 30 supported by the support member 31 so as to be slidable in the front-rear direction is coupled.
[0035]
A plunger 32a of a solenoid 32 fixed to the back surface 1b of the game board 1 is supported by a bracket 33 so as to be slidable. A tip of the plunger 32a is coupled to the transmission rod 30 and a peristaltic lever 34 is coupled thereto.
[0036]
In a state where the solenoid 32 is demagnetized and the plunger 32a is moved downward, the obstacle member 8A is retracted to the rear of the game area 2 and the ball flow path just above the right exercising port 5b is opened.
[0037]
In a state in which the solenoid 32 is excited and the plunger 32a is retracted upward, the obstacle member 8A advances into the game area 2 immediately above the right exercising port 5b, and the ball passage just above the right exercising port 5b is formed by the obstacle member 8A. Even if the ball is blocked and the game ball passes through the ball hole 18 and falls right above the right exercise port 5b, the game ball is rebounded by the obstacle member 8A and falls around the right exercise port 5b.
[0038]
According to the second embodiment, it is possible to cause a situation in which winning to the right exercise slot 5b becomes impossible.
