Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention provides a central winning a prize provided with a ball flow path conversion member in which a movable member is converted by a ball hitting a specific winning opening and the flow path of the ball is converted. The present invention relates to a pachinko machine provided with a device.
<Prior Art> A conventional pachinko machine, as typified by a so-called tulip, is provided with a variable winning device having a movable ball receiving member, and when a specific condition is satisfied, a tilt stop position of the movable ball receiving member is set. Convert, guide the hit ball to the winning opening by the movable ball receiving member,
I was changing the probability of hitting a ball.

<Problems to be Solved by the Invention> In the above-described conventional pachinko machine, when the movable ball receiving member of the variable winning device converts the hit ball into a state in which it is easy to win, most of the hit balls that have flowed down are won. Therefore, if the probability that the specific condition is satisfied is set to be high, the so-called payout rate is abnormally increased, and it is not possible to secure an appropriate profit for the pachinko parlor.

However, if the probability that the specific condition is satisfied is set to be low, the frequency at which the movable ball receiving member wins the hit ball becomes unnecessarily low, and even if a variable winning device having a bendable movable ball receiving member is provided, it does not affect the player. Will betray the expectation of winning a large number of prize balls and spoil the interest of pachinko games.

Conventionally, at the pachinko parlor side, the obstacle nails are adjusted while balancing the profits of the pachinko parlor and the player so that the player can enjoy the game by appropriately hitting the ball and the pachinko parlor can obtain the proper profit. Therefore, the probability of occurrence of the specific condition is adjusted, and the payout rate is set. However, since adjusting the obstacle nail requires a high-level technique based on intuition, it is actually difficult to achieve the expected payout rate, and a large error is likely to occur.

In recent years, there is a significant shortage of skilled persons to properly adjust obstacle nails, and it has become more difficult than ever to properly adjust the payout rate of a large number of pachinko machines.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and forms a game section surrounded by guide rails on the surface of the game board, and in the game section,
A movable member can be converted into a first state and a second state by a ball hitting a specific winning opening, and in the first state and the second state of the movable member, the flow of the ball dropped by the action of the movable member. A sphere flow path conversion member that makes the paths different, a special winning opening arranged below the sphere flow path converting member, and a variable guide portion located in the vicinity of the special winning opening for hitting the special winning opening. A central winning device having a guiding member that affects the ease of entering is provided, and a variable winning device that can change the receiving state of a hit ball by a movable ball receiving member.

<Operation> The probability of entering the specific winning opening is adjusted by arranging the nails and adjusting the nails to increase the probability of winning the specific winning opening. The ball flow conversion member is the first due to the hit ball winning this specific winning opening.
Even if the probability of converting the state to the second state and flowing the hit ball toward the special winning opening that gives a relatively large profit to the player is high, the probability that the hitting ball enters the special winning opening due to the action of the guiding member Changes, which allows players to play ball games with the expectation of winning a large number of prize balls, and to bring pachinko parlors with an appropriate amount of profit that can balance their profits.

<Examples> Examples of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the game board 1 of the pachinko machine has a game part 3 surrounded by a guide rail 2 on the surface thereof, and the game part 3 is formed.
The central prize device 4 is provided substantially in the center of the variable prize device 5a, 5b, 5c, 5d, which can change the receiving condition of the hit ball depending on the condition of the movable ball receiving member such as so-called tulip below the central prize device 4. 5e etc. are provided.

The central winning device 4 shells a sphere flow path converting member 7 on an upper portion of a substrate 6 mounted on the surface of the game board 1, and places a special winning opening 8 below the sphere flow path converting member 7 and the special winning opening. A guiding member 9 is arranged immediately below 8 and guide regulating members 11 and 11 also serving as lamp indicators are provided on the left and right of a ball dropping area 10 formed between the ball flow path converting member 7 and the special winning opening 8. It is made by projecting.

As shown in FIG. 4, the spherical flow path converting member 7 has a specific winning opening.
A support shaft 13 is provided below the substrate 6 on which the support shaft 12 is provided, and the support shaft 13 is provided.
The rotator 14 is rotatably supported on the base plate 6 as a variable member.
A frame 15 having an open lower surface is provided on the back side of the, and a rotary action member 16 for rotating the rotary body 14 by a ball hit through the specific winning opening 12 is provided in the frame 15. The rotating body 14 is provided with a first ball passage 17 and a second ball passage 18 that are slightly wider than the diameter of the ball, with their phases changed by about 180 degrees, and the ball guiding pieces 19, 19 are arranged on the left and right of the first ball passage 17.
A pair of permanent magnets 21a and 21b having different magnetic poles are provided on the left and right sides of a small hole 20 into which the shaft is rotatably mounted and into which the support shaft 13 is inserted so as to slightly project. On the other hand, the rotation acting member 16 has a short second ball mounting piece 23 substantially in the middle of the length of the long first ball mounting piece 22.
It has a T-shaped cross section intersecting at 90 degrees, and the first bar magnet 24a is attached to the tip edge of the first ball mounting piece 22 and the second ball mounting piece 2 is attached.
The tip edge of 3 has a second pole whose magnetic pole is opposite to that of the first bar magnet 24a.
A bar magnet 24b is attached and rotatably supported by a shaft 25 penetrating between both walls of the frame 1. Also, at the rear end of the frame 15,
A state detector 27 such as a photocoupler that operates by the light shielding plate 26 provided on the above-mentioned rotation acting member 16 is provided so that the state of the rotating body 14 can be detected by an electrical signal. The state detector 27 is not limited to the photocoupler, and may have any configuration as long as it can detect the state of the rotating body 14.

As shown in FIG. 7, the sphere flow path converting member 7 having the above-described structure always stops when the first sphere mounting piece 22 is substantially horizontal,
The N pole of the first rod magnet 24a approaching the substrate 6 and the S pole of the permanent magnet 21a provided on the rotor 14 and the S pole of the first rod magnet 24a and the rotor.
The N pole of the permanent magnet 21b provided in 14 attracts by magnetic action, and as shown in FIGS. 2 and 5, the rotating body 14 moves the first ball passage 17 upward and the second ball passage 18 downward. It stops in the first state toward. Then, in this first state, the ball guide pieces 19, 19 axially attached to the left and right of the first ball passage 17 hang down in a substantially vertical direction due to their own weight. Further, in the first state, the permanent magnets 21a, 21b protruding to the rear surface of the rotating body 14 are fitted into the recesses 28, 28 on the surface of the substrate 6 to lock the rotating body 14, so that the hit ball hits the rotating body 14. However, the rotating body 14 does not rotate.

In the above-mentioned first state, when the hit balls flow downward from the obliquely upper direction toward the central winning device 4, these hit balls pass through the flow path A shown by the one-dot chain line in FIG. 2, and most of them are the rotor 14 and the guide regulating member. The majority of these hit balls flow down without passing through the special winning opening 8 and flow down as they are, and a lucky hit ball is diagonally below the lower ends of the guide control members 11, 11. It hits the guide protrusions 29, 29 formed toward and enters the special winning opening 8. Then, when the hit ball that has flowed down from the upper part of the gaming section 3 toward the central winning device 4 is fortunately passed through the flow path B and enters the first ball passage 17 of the rotary member 14, the hit ball is rotated.
After falling on the ball receiving portion 30 formed in the central portion of the, the ball 6 passes through the specific winning opening 12 of the substrate 6 and is mounted on the first ball mounting piece 22, and rolls from the front end to the rear end. When the hit ball rolls to the rear end side of the shaft 25, the rotation acting member 16 is driven by the weight of the hit ball.
Rotates to convert the first ball mounting piece 22 from a substantially horizontal state to a substantially vertical state and the second ball mounting piece 23 from a substantially vertical state to a substantially horizontal state. When the rotation acting member 16 is converted into this state, the S pole of the second bar magnet 24b of the second ball mounting piece 23 which is close to the substrate 6 is rotated by the rotating body 1.
The north pole of the second rod magnet 24b faces the north pole of the permanent magnet 21b of the rotor 14, and the north pole of the permanent magnet 21b of the rotor 14 opposes the rotor 14 forward by the magnetic repulsive force of these same magnetic poles. As a result, both permanent magnets 21a, 21b are disengaged from the recesses 28, 28 of the substrate 6 and become rotatable. When the rotating body 14 becomes rotatable in this manner, the S pole of the second bar magnet 24b and the permanent magnet 2 provided on the rotating body 14
The N pole of 1b, the N pole of the second bar magnet 24b, and the S pole of the permanent magnet 21a provided on the rotating body 14 attract each other by magnetic action,
This suction force causes the rotating body 14 to rotate about 180 degrees,
As shown in FIGS. 6 and 6, the first ball passage 17 is converted to the second state in which the first ball passage 17 is directed downward and the second ball passage 18 is directed upward. In addition,
When the rotation acting member 16 rotates as described above, the first ball mounting piece 22
The upper hit ball falls from the open portion of the lower surface of the frame 15 and becomes a winning ball.

When the rotator 14 is converted to the second state, the left and right sphere guiding pieces 19, 19 of the first sphere passage 17 are rotated by their own weights in the direction in which each tip is tilted outward, and each tip is projected from the side surface of the rotator 14. Stop in the state where it was made. Therefore, most of the hit balls that have flowed down obliquely from above the central winning device 4 are received by the ball guide pieces 19 and 19, and these hit balls are discharged from the second ball passage 18 of the rotating body 14 to almost the center of the ball drop area 10. However, it can be dropped toward the special winning opening 8 (flow path C). In this way, when the rotating body 14 is changed from the first state to the second state, the flow path of the hitting ball flowing down is switched to the flow path C, and the rotation direction is changed to a direction in which the special winning opening 8 is easily entered.

Then, in the second state, when the hit ball that has flowed down from above enters the second ball passage 18, the hit ball is hit by the ball receiving portion 30 of the rotating body 14.
After falling onto the second ball mounting piece 23 through the specific winning opening 12 of the substrate 6. When the hit ball is placed on the second ball placing piece 23, the rotation acting member 16 is returned and turned by the weight of the hit ball, and the second ball placing piece 23 is changed from the substantially horizontal state to the substantially vertical state to the first ball placing piece. 22 is converted from a substantially vertical state to a substantially horizontal state. When the rotation acting member 16 returns to this state, the first ball mounting piece 22 approaching the substrate 6
Of the first bar magnet 24a is the S pole of the permanent magnet 21a of the rotor 14, and the N pole of the first bar magnet 24a is the N pole of the permanent magnet 21b of the rotor 14.
The rotor 14 is pressed forward by the magnetic repulsive force of these same magnetic poles facing the poles, so that both permanent magnets 21a and 21b are attached to the substrate 6.
It is disengaged from the recesses 28, 28 and is in a rotatable state. When the rotating body 14 becomes rotatable in this manner, the S pole of the first rod magnet 24a and the N pole of the permanent magnet 21a of the rotating body 14, the N pole of the first rod magnet 24a and the permanent magnet 21b of the rotating body 14b. And the S poles of each of them are attracted to each other by magnetic action, and the attracting force causes the rotor 14 to move to approximately 18
It rotates 0 degrees to return to the first state in which the second ball passage 18 is directed downward and the first ball passage 17 is directed upward. The rotation acting member 16
When is returned and rotated as described above, the hit ball on the second ball mounting piece 23 falls from the open portion of the lower surface of the frame 15 and becomes a winning ball.

Special winning opening 8 provided below the above-mentioned spherical flow path converting member 7
Is a through hole formed in the substrate 6, and sphere blocking members 31, 31 are projectingly provided on the left and right of the through hole.

As shown in FIG. 8, the guiding member 9 provided immediately below the special winning opening 8 has a ball receiving projection 33, which has a side surface substantially flush with the peripheral edge of the disk 32, on the surface of the disk 32 in a phase of approximately 120 degrees. By changing the position and projecting, a substantially Y-shaped passage 34 is formed on the surface of the disk 32.
And a block 32 that projects from the periphery of the disk 32 facing the entrance and exit of each passage 34, and a rotary shaft 36 that projects from the back surface of the disk 32 has a cylindrical bearing 37 on the substrate 6. Through the
A rotation adjusting spring is provided in the middle of the rotation shaft 36 protruding to the back side of the substrate 6.
38 and a tubular locking member 39 with a collar are fitted to each other, and a retaining ring is fixed to the tip of the rotating shaft 36. Therefore, the guide member 9 having the above-described configuration can rotate the rotation adjusting spring 38 with a proper rotation resistance by the pressing force, and when the ball receiving projection 33 hits the ball, the falling force of the ball hits the ball. Rotate. Then, the rotated guiding member 9 is stopped, and as shown in FIG.
When the doorway of is located below the special winning opening 8, the passage between the left and right sphere blocking members 31, 31 and the passage 34 of the guiding member 9 communicate with each other, and the blocking piece 35 is located in front of the special winning opening 8. Therefore, even if a hit ball enters between the left and right ball blocking members 31, 31,
This hit ball passes through the ball blocking member 31, 31 from the passage 34 of the guiding member 9.
It flows down into the game section 3 again. Therefore, when the entrance / exit of the passage 34 of the guide member 9 is stopped below the special winning opening 8, even if the batted ball flows down between the ball blocking members 31, 31, the special winning opening 8 hardly wins. . On the other hand, when the guiding member 9 is stopped, as shown in FIG. 3, when the ball receiving projection 33 is located below the special winning opening 8, the side surface of the ball receiving projection 33 functions as a ball guiding surface. It becomes a state.
Therefore, when a ball hits between the left and right ball blocking members 31, 31, the ball is guided to the special winning opening 8.

When a hit ball enters the special winning opening 8, the three variable prize winning tools 5a, 5b, 5c convert the hit ball from a difficult-to-accept state to an easily-acceptable state. The variable prize equipment 5a, 5b, shown in FIG.
5c is a so-called tulip, which is a base plate
A pocket frame 42 with an open top is provided on the surface of 41,
A pair of movable ball receiving members 43, 43 is rotatably mounted in the pocket frame 42, and a swing plate is swingably mounted in a back frame provided on the back side of the base plate 41. The front end of the moving plate faces the lower ends of the movable ball receiving members 43, 43, and a solenoid is connected to the rear end of the swing plate. Therefore, when the special prize detector provided in the middle of the flow path extending from the special prize opening 8 detects a hit ball and issues a signal, each of the variable prize tools 5a, 5b,
The solenoid of 5c is excited, and the movable ball receiving members 43, 43 are rotated to increase the upper end interval of the movable ball receiving members 43, 43, so that the ball can be easily received, that is, the state is advantageous to the player. In addition, although each of the above-described variable prize winning tools 5a, 5b, 5c is configured to rotate the movable ball receiving members 43, 43 by driving the solenoid, the weight of the hit ball entering the special winning opening 8 is used. You may make it rotate.

Next, a game in the pachinko machine having the above-mentioned configuration will be described. In addition, for convenience of explanation, the rotating body 14 of the spherical flow path converting member 7 is in the first state, and each of the variable winning tools 5a, 5b,
It is assumed that 5c is unacceptable to the player because it is difficult to accept a hit ball.

In this state, even if the hit ball flows through the flow path A between the rotating body 14 of the central winning device 4 and the guide restricting members 11, 11, the probability of these hit balls entering the special winning opening 8 is high. Low. However, when the ball receiving projection 33 of the guide member 9 is located below the special winning opening 8, the side surface of the ball receiving projection 33 functions as a ball guiding surface, so that the center winning device 4 and the rotating body 14 are guided. There is a possibility that the hit ball that has flowed down between the restriction members 11 and 11 may enter the special winning opening 8. Therefore, in this state, it is more advantageous to aim the first ball passage 17 of the rotating body 14 to shoot a hit ball.

When the fired ball hits the first ball passage 17 of the rotating body 14 through the flow path B, the turning action member 16 is rotated by the hitting ball, and the rotating body 14 is rotated by about 180 degrees. In addition to being converted into two states, the lamps 44 in the guide regulating members 11, 11 based on a signal from the state detector 27, the lamp 4 on the back side of the guiding member 9
5,45 and the LEDs 46 ... Which are lined up on the left and right of the guide member 9 blink, and the player has changed the rotating body 14 to the second state, that is, the flow path of the hit ball has been changed from A to C and the special prize is given. The fact that it has been converted into a state in which it can easily enter the mouth 8 is visually displayed.

When the rotating body 14 is converted to the second state, the hit ball is a rotating body.
When entering the second ball passage 18 of 14, the rotating body 14 returns to the first state, which is disadvantageous. Therefore, be careful not to let the ball hit the second ball passage 18 and the rotating body 14 and the guide regulation member 11 A shot is shot aiming at between and 11. Rotating body 14 and guide regulation member
Most of the hit balls that have flowed down between 11, 11 are collected by the ball guide pieces 19, 19 of the rotating body 14 and discharged from the first ball passage 17. Therefore, the majority of these hit balls are 8
It flows down between the ball blocking members 31, 31 of. At this time, if the ball receiving projection 33 of the guide member 9 is stopped below the special winning opening 8, the hit ball described above enters the special winning opening 8. On the other hand, when the ball receiving projection 33 is not located below the special winning opening 8,
The hitting ball hits the ball receiving projection 33 to rotate the guide member 9 to change the stop position. In any case, the rotating body 14
When is converted to the second state, the flow path of the hit ball is switched from A to C and the downward direction of the hit ball is directed to the special winning opening 8. Therefore, when the rotating body 14 is stopped in the first state, the special winning is compared. The probability of winning in mouth 8 increases.

When a hit ball enters the special winning opening 8, the special prize detector detects the hit ball, so that the three variable prize winning tools 5a, 5b, 5c convert the hit ball into a condition in which it is difficult to accept the hit ball all at once. In this way, when the variable winning prizes 5a, 5b, 5c are converted into a state in which the hitting ball can be easily received, the hitting ball is shot to the left and right of the game unit 3 without aiming at the central winning device 4, and the variable winning prizes 5a, 5c.
It is more advantageous to win the prize in b, 5c. In addition, each variable prize
After hitting the ball into 5a, 5b, 5c and returning to a state where it is difficult to accept the hitting by the hitting, the ball is fired again to win the special winning opening 8. Then, when the special winning opening 8 is hit again, the hitting of the three variable winning tools 5a, 5b, 5c is converted into a state in which it is easy to accept, as in the above.

In this way, when the rotating body 14 maintains the second state, if a ball is shot aiming between the rotating body 14 and the guide regulating members 11, 11, the winning state is influenced by the stopped state of the guiding member 9. However, the rotating body 14 has the first probability of winning the special winning opening 8.
It becomes higher when compared to when stopped in the state. When the hit ball enters the second ball passage 18 of the rotating body 14, the rotating body 14
Returns from the second state to the first state and ends the game state advantageous to the player.

Therefore, by increasing the probability of entering the first ball passage 17 of the rotating body 14 to increase the probability of a game state advantageous to the player, and even if the interest of the game is improved, the special prize hole depending on the state of the guide member 9 Since the probability of winning 8 is converted, the hit ball that has flown into the central winning device 4 does not necessarily enter the special winning opening 8, and the so-called ball-out rate can be made appropriate.

The second embodiment of the central payout device 4 shown in FIG. 10 is provided with a spherical flow path converting member 7 having the same configuration as that of the first embodiment described above, and a guiding member 9 is provided below the spherical flow path converting member 7. It is movably mounted on a shaft, and a special winning opening 8 is provided below the guiding member 9. In the guide member 9, as in the first embodiment, a spherical Y-shaped passage 34 is formed on the surface of the disk 32 by projecting the ball receiving projections 33 on the surface of the disk 32 while changing the phase by about 120 degrees. A ball hits the inside of the passage 34, or the ball hits a ball receiving projection.
It turns when it hits 33. Therefore, when the rotating body 14 is converted into the second state, when the hit ball discharged from the first ball passage 17 of the rotating body 14 enters the passage 34 of the guide member 9, the guide member is driven by its own weight and the downward force. 9 rotates. When the hit ball is discharged from the passage 34 above the special winning opening 8,
Enter the special prize hole 8.

The third embodiment of the central winning device 4 shown in FIG. 11 is a game board 1
The specific winning port 12 is provided at the upper end portion of the substrate 6 attached to the surface of the base plate, and a rod-shaped sphere flow path converting member 7'which can be undulated is disposed below the specific winning port 12 and the sphere flow path converting member is provided. Ball receiving shelves 47, 47 are formed on the left and right above 7 ', and a special winning opening 8 similar to that of the first embodiment is provided below the spherical flow path converting member 7'.
A guide member 9 is provided immediately below the guide wall, and guide walls 48 are formed on the left and right sides of a ball dropping area 10 'formed between the special winning opening 8 and the ball flow path converting member 7'. The sloped armor portions 49, 49 are formed from the upper ends of the walls 48, 48. In addition, in the above-mentioned spherical flow path converting member 7 ′, the end portion projected to the back side of the substrate 6 is connected to a solenoid. This spherical flow path converting member 7 '
Always stands in a substantially right angle with respect to the substrate 6 and is stopped in the first state in which the entrance of the ball falling area 10 'is blocked. Therefore, in this first state, the hit ball that has flowed down to the left and right ball receiving shelves 47, 47 falls through the space between the ball receiving shelves 47, 47 and hits the ball flow path converting member 7'and the ball dropping area 10 The hitting ball which has been prevented from flowing down to the ′ and has also flew from the lateral direction is the sphere flow path converting member 7 ′.
As a result, it is prevented from flowing down to the ball falling area 10 ', and flows down on the left and right inclined armor parts 49, 49. Therefore, the special winning opening 8 can receive a hit ball flying laterally below the inclined armor portions 49, 49.

On the other hand, when a ball hits the special winning opening 12 while the ball flow path converting member 7'is in the first state, the specific winning detector provided in the middle of the flow path extending from the specific winning opening 12 detects the hit ball. Then, the signal at this time excites the solenoid. When the solenoid is excited, the spherical flow path converting member 7'rotates in the direction in which the tip end thereof rises, and the spherical flow path converting member 7'is converted into the second state which is substantially flush with the substrate 6. When the ball flow path converting member 7'is converted to the second state, the hit ball dropped on the left and right ball receiving shelves 47, 47 flows between the ball receiving shelves 47, 47 and flows down in the ball falling area 10 'as it is. Further, a hit ball flying laterally between the ball receiving shelves 47, 47 and the inclined armor portions 49, 49 also enters the ball falling area 10 '. As described above, when the ball flow path converting member 7'is converted to the second state and the flow paths are switched so that the hit ball flows down in the ball falling area 10 ', the ball of the guiding member 9 is the same as in the first embodiment. When the receiving projection 33 is located below the special winning opening 8, the hit ball from the ball falling area 10 'wins the special winning opening 8 and the variable winning tools 5a, 5b, 5c easily receive the hit ball. Convert.

The ball flow path converting member 7'is configured to rotate by driving a solenoid. However, as shown in FIGS. 12 and 13, the weight of the hit ball in the specific winning port 12 is used. You may make it rotate. The drive mechanism of the spherical flow path converting member 7'shown in FIGS. 12 and 13 has a frame body 50 provided on the back side of the substrate 6, and a rotary plate 52 having a cam 51 in the frame body 50 as an axis.
It is rotatably supported by 53, and the tip of the rotating plate 52 is made to face the arm piece 54 of the spherical flow path converting member 7 '. In the first state in which the sphere flow path converting member 7'projects onto the surface of the substrate 6, the upper surface of the rotating plate 52 is slightly inclined downward toward the sphere flow path converting member 7 ', and the sphere flow path converting member is formed. The 7'arm piece 54 engages with the notch 55 of the cam 51. When the hit ball enters the specific winning opening 12 in this state, the hit ball is guided on the rotating plate 52. When the hitting ball is placed on the rotating plate 52, the hitting ball rolls due to the inclination of the upper surface of the rotating plate 52, and when the hitting ball rolls to the front of the shaft 53, the turning plate 52 moves in the direction of the arrow in FIG. 12 due to its own weight. Turn to. When the rotating plate 52 rotates, the cam 51 presses the arm piece 54, so that the spherical flow path converting member 7'rotates in the direction in which the tip end thereof rises, and the rotating plate 52 moves about 180 °.
When it is rotated, the spherical flow path converting member 7'is converted into a second state in which it is stopped substantially parallel to the substrate 6, as shown in FIG. In this second state, since the upper surface of the rotating plate 52 slightly inclines upward toward the spherical flow path converting member 7 ', when a hit ball from the specific winning opening 12 is placed on the rotating plate 52, The moving plate 52 returns and rotates due to the weight of the hit ball. Therefore, the spherical flow path converting member 7'returns and rotates in the direction in which the tip end is lowered, and returns to the first state shown in FIG.

Further, the variable prize device 5a, 5b, 5c in the present invention is not limited to the tulip type described above, and may have any configuration as long as it can change the receiving state of the hit ball depending on the state of the movable ball receiving member. For example, it may be a so-called rotary tulip in which a rotating body provided with a wide first ball receiving portion and a narrow second ball receiving portion with a phase difference of 180 degrees is rotatably attached to the surface of the substrate 6 so as to be rotatable.

<Effects of the Invention> As described above, according to the present invention, the probability of winning a special prize hole is increased by converting the flow path of a hit ball according to the state of the ball flow path conversion member, thereby increasing the number of prize balls for a player. You can give a sense of expectation. In addition, the probability of winning the special winning opening is not simply increased, but the probability of winning the special winning opening is appropriately adjusted depending on the state of the guide member, so that the specific condition that the ball channel converting member converts to the second state. Even if the probability that is established is set to a high value, it is possible to provide a player with an expectation of winning and to have a proper payout rate for a pachinko parlor. Therefore, compared to the conventional pachinko machine that adjusts the ball throwing rate by strictly adjusting the obstacle nail, the adjustment of the obstacle nail is almost unnecessary, and the profit balance of both the player and the pachinko parlor can be achieved practically. It is possible to provide a sound pachinko machine.
