Therefore, when the first solenoids 34, 34 are demagnetized,
The movable ball receiving members 15 and 15 are erected in an upright state by the urging of the return spring and the upper end stops inside the end of the armor portion 13, so that the falling ball is not received. That is, it is in the first state in which the ball that has flowed down does not flow into the opening 12. When the first solenoids 34, 34 are excited, the drive lever 38,
As the 38 descends, each support shaft 1
6 rotates and the first movable ball receiving members 15, 15 rotate in a direction in which the upper end is tilted outward, and stop in a state of slightly descending and leaning toward the base end side of the shaft attachment, and receive the falling ball, The state is changed to the second state in which it easily flows into the opening 12. In addition, the movable ball receiving member 15,1

As shown in FIG. 8, the rotating body 32 provided in the surrounding frame 30 is supported by the rotating shaft 39 at the substantially center of the length, and the gear 40 attached to the lower end of the rotating shaft 39 is provided with the speed reducer motor 41. When the motor 41 with a speed reducer meshes with the gear 42 of the output shaft and rotates according to a command signal from a control device (not shown), the motor 41 rotates according to the rotation. The rotating body 32, the motor 41, the control device, and the like form a storage mode conversion unit.

The storage mode conversion means can convert the ball storage state in the ball storage portion 31 into various modes by rotating the rotating body 32, and at least the longitudinal direction of the rotating body 32 is a concave chamber.
It is possible to convert into a first storage state (first storage state) located in the front-rear direction of 24 and a second storage state (second storage state) located in the width direction, and this first storage state Can be converted into various intermediate storage states that continuously change between the second storage state and the second storage state. The first and second storage states will be described later in detail.

A light blocking piece 43 is provided on the rotary shaft 39 of the rotary body 32. Therefore, when the rotating body 32 rotates, the light shielding piece 43 acts on the motor switch 44 including a photo sensor,
The position of the rotating body 32 can be detected by the motor switch 44, the control device can always know the position of the rotating body 32 based on the detection signal, and the rotating body 32 can be stopped at a predetermined position. Can be made.

Further, the storage control member 33 provided in the cutout portion of the surrounding frame 30,
As shown in FIGS. 6 and 7, a plate material curved in an arc shape is inserted through an arc-shaped through hole formed in the bottom surface 23 and extends from both ends of the drive shaft 45 supported below the bottom surface 23. The drive arms 46, 46 provided are holes 47, 47 opened at the bottom of the storage control member 33.
A drive shaft 45 that is loosely fitted inside and extends on the side opposite to the drive arm 46.
The connecting arm 48 of is connected to the plunger of the second solenoid 35. Therefore, when the second solenoid 35 is demagnetized, the plunger is moved upward by the urging of the return spring of the second solenoid 35, so that the tip ends of the drive arms 46, 46 are lowered, which causes the storage control member 33. Goes down into a first state in which the upper end is located at the same level as or lower than the upper surface of the bottom surface 23. Therefore, in this first state, the storage control member 33 does not prevent the spheres in the sphere storage portion 31 from flowing down. Then, when the second solenoid 35 is excited, the plunger is lowered and the drive shaft 45 is rotated in a direction in which the tips of the drive arms 46, 46 are raised, so that the storage control member 33 rises and projects onto the bottom surface 23. To the second state. In this way, the storage control member 33
When projecting on the bottom surface 23, the storage control member 33 closes the outflow portion 29 of the surrounding frame 30, so that the balls in the sphere storage portion 31 are prevented from flowing down by the storage control member 33 regardless of the state of the rotating body 32, Stand by in the ball storage unit 31. When the second solenoid 35 is demagnetized, the storage control member 33 is urged by the urging of a return spring or the like.
Is returned to the first state in which it descends below the bottom surface 23, so that the balls in the ball storage portion 31 can flow out from the outflow portion 29, and the balls that have come out roll on the bottom surface 23 and the special winning opening 19 or general Winning mouth
Win 20.

Each ball blocking member 21 provided on the left and right of the general winning opening 20, 20,
As shown in FIG. 10 and FIG. 11, the upper end of the hook-shaped member is rotatably supported by the support shaft 22, and the two stopper shafts 49, 49 extended to the public information are regulated by the third solenoid 36. It faces the member 50. Therefore, when the third solenoid 36 is demagnetized, the restricting member 50 rises and presses the stopper shafts 49, 49 due to the urging of the return spring of the third solenoid 36, so that the ball blocking member 21 rotates. It is blocked and stops in the neutral state shown by the solid line in FIG. When the rotation of the ball blocking member 21 is blocked in this manner, the ball flowing down on the surface of the game board 1 is blocked by the ball blocking member 21 as shown by the alternate long and short dash line in FIG.
Even if the ball hits, the ball blocking member 21 does not rotate. Therefore, the ball is bounced back and the flow direction is changed to the direction shown by the alternate long and short dash line to flow down, and the obstacle nail is planted below the variable winning device 6. It does not flow into the constructed guide flow-down passage 51. On the other hand, when the third solenoid 36 is excited, the regulating member 50 descends and separates from the stopper shafts 49, 49, so that the ball blocking member 21 is converted into a freely rotatable state. When the sphere that has flowed down in this state hits the sphere blocking member 21, the sphere blocking member 21 rotates in the direction in which the lower end moves inward due to the falling force of the sphere. Therefore, the ball that has flowed down can be pushed away from the ball blocking member 21 and flow into the guide flow path 51. Since the exit of the guide flow-down passage 51 is open above the first specific winning opening 7, the balls flowing into the guide flow-down passage 51 are the first specific winning opening 7
The chances of winning a prize increase. That is, the third solenoid 36
Is excited to convert the ball blocking member 21 into a swingable state, the winning probability to the first specific winning port 7 is temporarily increased, and the movable ball receiving members 15 and 15 of the variable winning device 6 open. Is increased. The swing range of the ball blocking member 21 is regulated by a rotation regulating hole 49 'which is opened in the mounting substrate 11 and penetrates the stopper shafts 49, 49.

Next, a game in a pachinko machine provided with the variable winning device 6 having the above-described configuration will be described. In addition, the movable ball receiving member 15, 15 of the variable winning a prize device 6, the first solenoid 34,
34 is degaussed, standing up and not accepting ball 1st
When the storage control member 33 is demagnetized by the second solenoid 35, the storage control member 33 sinks below the bottom surface 23 to open the outflow portion 29 of the storage portion, and the rotating body 32 is operated by the motor 41. Per minute
It rotates at a speed of 20 rotations, and the ball blocking members 21, 21 are locked so that they cannot swing because the third solenoids 36, 36 are demagnetized.

In this state, when the ball flowing down in the game section 3 enters the second specific winning opening 8, the second specific winning detector 10 detects this ball and sends a signal to a control device (not shown), so that the first Specific prize hole 7
When entering, the first specific winning opening 7 opens the ball receiving pieces 52, 52 to the left and right to convert the ball into a state in which it is easy to receive the ball, and
The specific prize detector 9 detects this sphere and sends a signal to the control device. When the control device receives the signal from the second specific winning award detector 10, it excites the first solenoids 34, 34 of the variable winning award device 6 for a short time (for example, only for 0.5 seconds after the wait time of 0.8 seconds has elapsed). , When the signal from the first specific winning award detector 9 is received, the first solenoids 34, 34 are excited only twice for a predetermined time (for example, 0.8 seconds after a wait time of 0.8 seconds has elapsed). Therefore, when the ball enters the first specific winning opening 7, the left and right movable ball receiving members of the variable winning device 6
When 15,15 is converted from the first state to the second state only twice for 0.8 seconds, and the ball enters the second specific winning opening 8, the movable ball receiving member 15,1
5 changes from the first state to the second state only once for 0.5 seconds.

In this way, when the movable ball receiving members 15, 15 of the variable winning device 6 are converted from the first state to the second state, the balls flowing down in the game section 3 flow down onto the movable ball receiving members 15, 15. , The sphere is from the opening 12 of the mounting substrate 11 to the upper chamber 24a in the concave chamber 24.
It enters and rolls on the downflow shelf 25, passes through the communication passage 27 at the back, and drops into the lower chamber 24b. When the sphere flows down in the communication passage 27, the sphere detector 28 detects the sphere and sends a counting signal to the control device. As for the sphere that has entered the lower chamber 24b of the recessed chamber 24, since the outlet of the communication passage 27 is located above the sphere storage part 31, most of the spheres once fall into the sphere storage part 31 and the outflow part 29. From the bottom
Roll over 23 and enter either the special prize hole 19 or the general prize hole 20. When the ball enters the general winning opening 20, this ball flows out to the back side of the game board 1 and becomes a winning ball, but there is no conversion to the gaming state. On the other hand, when the ball fortunately enters the special winning opening 19, the special winning detector 53 provided in the flow path extending from the special winning opening 19 detects the ball and the controller has the right to the special game. Send a signal to the effect. The ball that entered the special winning opening 19 flows out to the back side of the game board 1 and becomes a winning ball.

When the control device receives a signal from the special prize detector 53,
Special games are started.

In the special game in this embodiment, first, the variable winning device 6
The second solenoid 35 is excited to raise the storage control member 33 to close the outflow portion 29 of the ball storage portion 31, and the third solenoid 36 is excited to convert the ball blocking member 21 into a freely swingable state. In addition, the rotating body 32 is temporarily stopped at the initial position. In the present embodiment, when the light blocking piece 43 acts on the motor switch 44, the position where the longitudinal direction of the rotating body 32 faces the front-back direction of the concave chamber 24 and the rotating body 32 stops is set as the initial position, and the movable position is set. It is set so that the rotator 32 starts to rotate from the initial position again when the ball receiving members 15, 15 start the opening / closing operation. In addition, the second solenoid 35 and the third solenoid 36 must be excited during the special game, and as a result, the solenoid gradually heats up and the resistance increases, and the attraction force becomes weak at the next attraction. Therefore, the storage control member 33 cannot be raised, or the ball blocking member 21 cannot be freely swung. Therefore, in order to prevent such inconvenience, the control device of the present embodiment uses a CPU.
By control, a large amount of power is supplied to the energized second solenoid 35 and the third solenoid 36 during suction, and a small amount of power is supplied when suction is completed and each plunger is maintained to maintain the state of each solenoid. Is configured to. As shown in FIG. 21, the second solenoid 35 and the third solenoid 36 suppress the heat generation by repeating excitation / demagnetization for a very short time (for example, 0.04 seconds) after being excited for 0.5 seconds. After the preparatory operation, the variable ball receiving members 15, 15 of the variable winning device 6 are delivered a predetermined number of times for a predetermined number of times (for example, 0.8
One cycle is to convert from the first state to the second state only 18 times per second), and the cycle is updated on the condition that the ball enters the special winning opening 19 during this cycle or after the cycle ends. If the ball does not enter the special winning opening 19, the special game is set to end with the cycle regardless of the number of remaining cycles. Further, the cycle can be updated up to a predetermined number of times (for example, 8 cycles), and even if a ball enters the special winning opening 19 after that, the special game is set to end. The number of cycles during the special game is visually displayed on the cycle display 54 provided in the lower ball receiving frame 18. Further, the number of winning balls to the variable winning device 6 during a certain cycle is a predetermined value (for example, 10
It is set so that the cycle is ended at that time regardless of the number of remaining opening / closing times of the movable ball receiving members 15, 15. The number of balls that has entered the variable winning device 6 in the cycle is visually displayed to the player by the winning number display 55 provided at the tip of the falling shelf 25.

When the above-mentioned special game is started and the movable ball receiving members 15, 15 of the variable winning device 6 start the opening / closing operation, the ball received by the movable ball receiving members 15, 15 is the upper chamber 24a in the concave chamber 24.
These spheres are successively introduced into the lower chamber 24b after being detected by the sphere detector 28 when passing through the communication passage 27. The sphere that has entered the lower chamber 24b from the outlet of the communication passage 27 once falls into the sphere storage portion 31 on the bottom surface 23, but in this sphere storage portion 31, the rotating body 32 is rotating, and storage control is performed. The member 33 blocks the outflow portion 29 of the sphere storage portion 31. Therefore, most of the balls that have fallen are stored while being dropped in a substantially semicircular portion surrounded by the surrounding frame 30, the storage control member 33, and the rotating body 32, and then fall onto the upper surface of the rotating body 32. The ball that bounces or rolls out from the ball storage portion 31 rolls on the bottom surface 23 and enters the special winning opening 19 or the general winning openings 20, 20. In the embodiment shown in the drawings, three spheres are stored in the substantially semicircular portion of the sphere storage portion 31, so that
A ball that has fallen further to this part when it is full rolls over the already stored ball and the ball storage part 31
Exit from the special prize hole 19, or general prize hole 20,20.
Further, the spheres stored in the storage section continue to join together along the surrounding frame 30 and the storage control member 33 by the rotation of the rotating body 32. When a ball enters the general winning opening 20, this ball flows out to the back side of the game board 1 and becomes a winning ball, but the game content is not converted.
On the other hand, when a ball enters the special winning opening 19, the special prize detector 53 detects the ball and sends a signal to the control device. Upon receiving this signal, the control device updates the cycle, demagnetizes the second solenoid 35, and once lowers the storage control member 33 to open the outflow portion 29 of the ball storage portion 31. Therefore, the balls stored in the ball storage portion 31 come out of the outflow portion 29 and enter the special winning opening 19 or the general winning opening 20. Further, in a certain cycle, if the movable ball receiving members 15, 15 are opened and closed a predetermined number of times (18 times in this embodiment), but the ball has not entered the special winning opening 19 by then, the control device determines that the second solenoid
It is set to demagnetize 35. Therefore, also in this case, the balls stored in the ball storage unit 31 come out of the outflow unit 29 and enter the special winning opening 19 or the general winning opening 20. In addition,
As shown in FIG. 12, when the storage control member 33 descends in the first storage state in which the longitudinal direction of the rotating body 32 is located in the front-back direction of the concave chamber 24, the balls stored on both sides of the rotating body 32 are Since they flow down, these balls have a high probability of entering the right and left general winning openings 20,20. Further, as shown in FIG. 15, when the storage control member 33 descends in the second storage state in which the longitudinal direction of the rotating body 32 is located in the width direction of the recessed chamber 24, the storage control member 33 is positioned substantially on the storage section 29 side. Since the three balls stored in the semicircle part flow down all at once, the ball in the center is the special prize hole 19 and the left and right balls are the general prize holes 20,20 as shown in FIG. The probability of entering is high. Therefore, when the predetermined number (10 in this embodiment) of balls are won in the variable winning device 6, the ball detector 28 detects these balls and the control device counts up to the predetermined number, the cycle is finished. Although it has been set, even if a predetermined number of balls have won in the cycle and still have not entered the special winning opening 19, the balls stored in the ball storage unit 31 as described above are special. By increasing the probability of entering the winning hole 19, the possibility that the game can be updated in the next cycle is increased, and the game that is advantageous to the player can be continued. Then, when the cycle ends and the rotating body 32 further rotates, as shown in FIG. 19, the spheres stored in the approximately semicircular portion on the opposite side flow out from the outflow portion 29. If the winning in the special winning opening 19 has not been achieved, there is a chance that the balls that have flowed down afterwards enter the special winning opening 19. Therefore, according to the present embodiment, even if there is no prize in the special prize hole 19 just before the number of prize balls reaches a predetermined number, it is possible to leave a high possibility of winning in the special prize hole 19 and to finish the special prize. The feeling of expectation for the mouth 19 acts stronger than that of the conventional variable winning apparatus 6, and thus the interest of pachinko games can be greatly enhanced.

The magnetism for moving the storage control member 33 down is not limited to the one cycle of the special game as in the above-described embodiment, but may be set in any manner. For example, it may be when the time set in the timer of the control device has elapsed during the cycle, or the player can descend at any time by operating the external operation unit on the front of the pachinko machine. You may. If the storage control member 33 can be lowered by an external operation of the player, it can be lowered in consideration of the position of the rotating body 32, so that the special winning opening 19 can be aimed.

In addition, a special prize detector that causes special games
The first storage state and the second storage state are controlled so as to be changed appropriately according to the detection timing of 53 or the number of continuations (cycles). For example, the later the detection timing of the special prize detector 53 is, or the number of continuations is longer. The less the second
If it is controlled so as to be easily stored, the probability of winning the special winning opening 19 in one variable winning device 6 is different,
You can play a variety of games.

Further, during the special game described above, since the third solenoid 36 is excited, the ball blocking members 21, 21 provided on the left and right of the lower portion of the variable winning device 6 can freely swing. Therefore, when a ball that has flowed down the side of the variable winning device 6 or a ball that has flowed obliquely downward when the movable ball receiving members 15 and 15 are closed hits the ball blocking member 21, this ball will move the ball blocking member 21. It becomes possible to push it away and flow into the guide flow-down passage 51.
Therefore, during the special game, the winning probability to the first specific winning opening 7 is temporarily increased compared to the normal gaming state, and the movable ball receiving members 15, 15 of the variable winning device 6 are reopened. The probability that the right to the special game is generated is increased.

Note that the above-mentioned sphere storage section 31 is not limited to the configuration surrounded by the surrounding frame 30, but any configuration is possible as long as the sphere received by the movable sphere receiving members 15 and 15 can be temporarily stored in the concave chamber 24. Alternatively, for example, a recess may be formed on the bottom surface 23 of the recess chamber 24 to configure the recess. Further, the storage control member 33 provided in the outflow portion 29 of the ball storage portion 31 does not have to move up and down, but if the flow down of the balls in the ball storage portion 31 can be controlled by the operation of the electric drive source. Such a configuration may be used, and for example, the plate material or the protection material may be moved in the left-right direction.

<Effects of the Invention> As described above, according to the present invention, a change in the storage state of the spheres by the storage mode conversion unit causes a change in the winning probability to the special winning opening when the storage is released. Even if there is no prize in the special prize hole just before reaching, it is possible to leave a high possibility of winning in the special prize hole, and the expectation for the special prize hole will be strongly exerted until the end, which will enhance the fun of the game. Can be significantly elevated.
