Abstract

PURPOSE:To make it possible to adjust a probability that a shot pinball enters a variable device for prize-winning pinballs or a specific prize-winning pocket without much dependence on the adjustment of nails by providing a controlling device for driving movable members in a first-condition according to an output transmitted from a detecting device for a specific playing condition and an adjusting device for a movable range of a movable members. CONSTITUTION:In the case where a shot pinball falls on the same vertical line C in a playing zone 13, when a shot pinball P1 falls on a movable member 63a set at a small tilt angle theta1, it is held on the movable member 63a and led to the side of a prize-winning zone 52 and turned to a prize-winning pinball. On the other hand, when a shot pinball P2 falls on the movable member 63a set at a large tilt angle theta2, it falls on the side of the playing zone 13 after crashing against the top end of the movable member 63a. For this reason, a probability that a shot pinball enters a variable device 50 for prize-winning pinballs can be variously controlled by adjusting the tilt angle of the movable members 63a, 63b, i.e. the movable range thereof, by means of an adjusting mechanism 85. Therefore, anyone can simply and easily adjust the probability that the shot pinball enters the variable device 50 for prize-winning pinballs without much dependence on the adjustment of nails instead of depending on the adjustment thereof as before.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides a variable prize winning ball that has a movable member that can be moved between a first state that is advantageous to the player and a second state that is disadvantageous to the player. a device, a specific gaming state detection means for detecting that the gaming state has reached a predetermined specific gaming state, and a drive for controlling the movable member to a first state in accordance with an output of the specific gaming state detection means. The present invention relates to a pinball game machine including a control means.

[Prior Art] Conventionally, a ball is equipped with a variable winning ball device in which a movable member moves when the gaming state reaches a predetermined specific gaming state to change the state to a state advantageous to a player who is likely to hit a winning ball. Gaming machines were being offered on the market. Moreover, some of such variable winning ball devices had a specific winning hole inside. In such a pinball game machine, since the movable range of the movable member is constant, the winning rate of balls hitting the variable winning ball device or the winning rate of balls hitting a specific winning opening tends to be constant. However, it was not possible for the game hall to change the winning rate of the variable winning ball device or the winning rate of a specific winning hole. For this reason, in order to make the winning rate for the variable winning ball device or the winning rate for the specific winning hole the winning rate desired by the gaming hall, the obstacle nails planted around the variable winning ball device are adjusted. The winning rate of balls hit was adjusted.

[Problems to be Solved by the Invention] However, in the above-mentioned pinball game machine, the winning rate of the variable winning ball device or the winning rate of the specific winning ball can be changed by adjusting the nails planted around the variable winning ball device. Since the winning rate is greatly influenced, delicate adjustment is required, and there is a problem that anyone cannot easily adjust the winning rate of the variable winning ball device or the winning rate of a specific winning hole.

This invention was made in view of the above-mentioned problems, and its purpose is to adjust the winning rate to the variable winning ball device or the winning rate to a specific winning hole without relying too much on nail adjustment. Our goal is to provide a pinball game machine that can.

[Means for Solving the Problems] In order to achieve the above object, the pinball game machine according to the present invention has the following features: a first state that is advantageous to the player and a second state that is disadvantageous to the player. A variable winning ball device having a movable movable member; a specific gaming state detecting means for detecting that the gaming state has become a predetermined specific gaming state; and a variable winning ball device having a movable movable member; The movable member is configured to include a drive control means for driving and controlling the movable member to a first state, and a movable range adjusting means for adjusting the movable range of the movable member.

Further, in place of the movable range adjusting means, the movable position changing means changes the movable range of the movable member to a plurality of types of movable positions, and probability adjusting means adjusts the probability of appearance of the plurality of types of movable positions. [Function] The movable range of the movable member is changed by the operation of the movable range adjusting means, so that the ball hitting the ball falling in the game area can be adjusted. The range in which winning can be stopped or the falling state of the ball is different, and the winning rate to the variable winning ball device or the winning rate to the specific winning hole can be adjusted.

In addition, by changing the movable position of the movable member to a plurality of different positions by the movable position changing means and adjusting the probability of appearance of the plurality of movable positions by the probability adjusting means, the catch of the hit ball falling in the game area can be reduced. The stopping range or the falling state of the ball is different, and the winning rate to the variable winning ball device or the winning rate to the specific winning hole can be adjusted.

Next, the first state is advantageous to the player, and the second state is disadvantageous to the player.
Regarding the configuration of the variable prize winning ball device 50 having movable members 63a and 63b that can be moved to the state shown in FIGS. 1A to 3,
This will be explained with reference to the figures.

The variable prize winning ball device 50 has a mounting board 51 that is attached to the game board 11, and a rectangular box frame 53 with an open front is formed projecting from the center rear of the mounting board 51. The inside of the frame 53 is a winning area 52.

An armor part 54 is protruded from the upper part of the front end of the winning area 52, and an upper decorative plate 55 is fixed to the front surface of the armor part 54. A normal winning opening 56 is formed. In addition, this upper decorative plate 5
At the center of 5 is a winning number display LED 57 that displays the number of winning balls hit by the variable winning ball device 50 and detected by the 10 count detection switch 24, and 1! of the opening/closing cycle described above. A continuation number display LED 58 that notifies the number of continuations (8 times) is arranged so as to face the front.

Further, a lower frame 59 is protruded from the lower front end of the winning area 52, and a lower armor plate 60 is fixed to the front surface of the lower frame 59. Further, a lower frame 59 is provided on the rear surface of the lower decorative plate 6o.
Specific winning a prize opening forming members 61a and 61b which partition the space surrounded by into three parts are detachably attached. And, the center space is made into the specific winning a prize opening 61, and the space on either side is made into the normal winning a prize opening 62a, 62b. When a ball hits the specific winning hole 61, the specific winning ball detection switch 23 is turned on to enter a specific gaming state, and the movable members 63a, 63b perform a predetermined opening/closing cycle operation as described above.

Further, a pair of movable members 63a and 63b are supported by glaze on the left and right sides of the center of the front end of the award entry area 52 so as to be openable and closable. The movable members 63a, 83b are rotatably supported around support shafts 65a, 65b, and protrusions 64a, 64b are formed at their bases. This protrusion 64a,
Reference numeral 64b serves to inhibit the flow of balls with little momentum, which are stopped by the movable members 63a and 63b. In addition, a ball hit with momentum that is stopped by the movable members 63a and 63b overcomes the protrusions 64a and 64b and falls downward without being hindered from flowing down.

The support shafts 65a, 65b of the movable members 63a, 63b are
As shown in FIG. 3, it is supported through support tubes 66a and 66b formed on the rear surface of the mounting board 51, and link members 87a and 67b (however, 67b is not shown) are fixed to the rear ends. A movable member drive solenoid 7 is connected to the link members 67a, 87b via actuating members 68a, 68b.
3a, 73b, the movable member drive solenoid 73
Movable members 63a and 6 correspond to the energization and de-energization of a73b.
3b alternately changes between an open state in which the ball is received and a closed state in which the ball is not received. Also,
The actuating members 68a, 68b are provided with "" that protrudes forward.
L-shaped arm portions 69a and 69b (69b is not shown) are formed in one piece, and their tips abut against an abutting inclined surface 92 of an adjustment mechanism 85, which will be described later. In addition, the plungers v71a and 71b (however, 71b is not shown) of the movable member drive solenoids 73a and 73b are as follows:
Return springs 72a and 72b are provided to always bias the movable members 63a and 63b to the closed state, and the tips of the plungers 71a and 71b hit a stopper portion 83 formed at the lower end of the solenoid mounting plate 81. Also, movable member drive solenoids 73a and 73b are in contact with each other.
is a mounting boss 80 protruding from the back surface of the mounting board 51.
The solenoid mounting plate 81 is fixed to a metal solenoid mounting plate 81 which is fixed to a metal solenoid mounting plate 81, and the solenoid mounting plate 81 has an operating member guide elongated hole 82a82b and an opening through which the arm portions 69a, 69b of the operating members 68a, 68b pass through. 84 have been established. This opening 84 is provided so that an operating section 94 of an adjustment mechanism 85, which will be described later, protrudes rearward.

By the way, a guide plate 74 that gently slopes from the front to the rear is lying at approximately the center of the award entry area 52, and a guide wall 75 extends from the right and left front ends of the guide plate 74 toward the rear center.
a, 75b are formed. The guide plate 74 is designed to guide balls that are hit with less force among the balls that are stopped when the movable members 63a and 63b are in the open state, and the guided balls are guided to the guide plate 74. is the guide wall 75a.

It is guided by 75b and falls downward from the falling lower aro formed at the center behind it. This falling lower aro is the guide plate 7
4 and a rear plate 77 which is the rear wall of the box frame 53. A normal rolling plate 78 is formed which is inclined from the lower end of the rear face plate 77 toward the specific winning opening 61 and the normal winning openings 62a, 62b. Since the falling lower roller is formed at the center of the rear part of the guide plate 74, the ball that has fallen from the falling lower roller will reach the normal rolling plate 78.
There is a high possibility that the prize will flow down approximately in the center, and therefore, there is a high possibility that the prize will be won in the specific winning hole 61 located in the center.

On the other hand, an obstacle member 79 that protrudes rearward is provided on the upper part of the lower decorative plate 60, so that balls directly falling from the movable members 63a and 63b collide with each other and are distributed to the left and right. That is, as soon as the movable members 63a, 63b are in the open state, the ball that is hit with a large force among the balls that are stopped by the receiver is hit by the protrusions 64a, 6 of the movable members 63a, 63b.
4b, there is a high possibility that the ball will directly fall downward from between the movable members 63a and 63b without being guided onto the guide plate 74.
There is a high possibility that the winnings will collide with each other and be distributed to the left and right, and be guided to the normal winning holes 62a and 62b located on the left and right.

An adjustment mechanism 85, which is the main part of this embodiment, is provided between the rear plate 77 and the solenoid mounting plate 81.

The adjustment mechanism 85 includes a storage frame 8 fixed to the rear plate 77.
6. That is, so as to be supported by receiving portions 87a and 87b formed on both left and right sides of the storage frame 86,
An operating shaft 88 having a threaded portion (male thread) 89 is supported,
A stopper member 90 is screwed onto the operating shaft 88 via a threaded receiving portion (female thread) 91 made of metal (for example, brass or the like) so as to be movable in the left and right direction. The lower end of the stopper member 90 constitutes an abutting inclined surface 92 that rises and inclines toward the rear, and this abutting inclined surface 92 contacts the operating member 68.
a, 68b and contact portions 70a, 70b. Note that guide shafts 93a and 93b (however, 93b is not shown), which accurately guide the movement of the stopper member 90 in the front-back direction, are provided on the left and right upper ends of the stopper member 90 so as to pass through the stopper member 90. Storage frame 86
Fixed. Furthermore, an operating section 94 that can be operated with an operating tool such as a screwdriver is fixed to the rear end of the operating shaft 88 by a fixing screw 95. As described above, the operating portion 94 passes through the opening 84 of the solenoid mounting plate 81 and protrudes rearward therefrom.

Since the adjustment mechanism 85 is configured as described above, the stopper member 90 moves in the front-rear direction by rotating the operating portion 94 with the operating tool.

Then, since the abutting inclined surface 92 also moves B in the front-back direction, the abutting positions of the actuating members 68a, 68b with the abutting portions 70a, 70b are different. For example, a stopper member 90
When the rear end of the contact inclined surface 92 and the contact portions 70a, 70b are in contact with each other, when the movable member drive solenoids 73a, 73b are energized, the plungers 71a, 71b are at the most elevated position. Since the movable members 63a and 63b are in the most open state,
When the stopper member 90 is located at the rearmost position, the front end of the contact slope 92 contacts the contact portion 70a70b, so that when the movable member drive solenoids 73a, 73b are excited, the plungers 71a, 71b are located at the rearmost position. Since the movable member 63a63b is sucked only to a position below the raised position, the movable member 63a63b is driven and controlled so as to open only in a state where the movable range is smaller than the most open state. Therefore, by operating the operating section 94, the stopper member 90
By changing the positions of the movable members 63a and 63b, the movable range of the movable members 63a and 63b can be adjusted.

The movable members 63a, 6 are adjusted by the adjustment mechanism 85 as described above.
3b can be adjusted, so in the variable winning ball device 50, as shown in FIGS. 1A and 1B, the inclination angle of the movable member 63a (the other movable member 63b is omitted) can be adjusted. When the tilt angle θ1 is adjusted to be relatively small and the tilt angle θ2 is relatively large,
Even if the hit ball falls on the same vertical line C (vertical line drawn at the tip of the movable member 63a) in the game area 13, the hit ball Pl that falls on the movable member 63a with a small inclination angle θ is
The hit ball P2 is stopped by the movable member 63a and guided to the winning area 52 side to become a winning ball, whereas the hit ball P2 that has fallen onto the movable member 63a with a large inclination angle θ2 is stopped by the movable member 63a.
The ball collides with the tip of the ball and falls to the gaming area 13 side.

Therefore, the adjustment mechanism 85 adjusts the inclination angle of the movable members 63a, 63b, that is, the movable range of the movable members 63a, 63b.
Since the winning rate of balls hit into the variable winning ball device 50 can be controlled to be different by adjusting the It can be easily and easily adjusted.

In addition, in the illustrated variable winning ball device 50, the ball P3 that has been stopped and guided by the movable member 63a with a small inclination angle θ1 has a small momentum to transfer on the movable member 63a, so the ball P3 moves past the protrusion 64a. There is a low possibility that the ball will get over the ball, and it will be transferred from the movable member 63a to the guide plate 74, and guided by the talking wall 75a, it will fall from the falling Roaro to the center of the ball transfer plate 78,
There is a high possibility that the ball will flow down the ball transfer board 78 as it is and win a prize in the specific winning hole 61. For this reason, it is possible to increase the probability of appearance of a specific gaming state at the time of starting winning or the continuation rate during the opening/closing cycle.

On the other hand, the hit ball P4, which is stopped and guided by the movable member 63a having a large inclination angle θ2, has a large momentum of moving on the movable member 63a, so there is a high possibility that it will climb over the protrusion 64a, and the ball P4 will move over the movable member 63a.

63b towards the obstacle member 79, and is distributed to the left and right by the obstacle member 79 and enters the normal winning slots 62a, 6.
There is a higher possibility of winning 2b.

Therefore, it is possible to suppress the appearance probability of a specific game state at the time of starting winning or the continuation rate at the time of the opening/closing cycle to be low.

As mentioned above, in the pachinko game machine equipped with the variable winning ball device 50 in this embodiment (first embodiment),
Conventionally, the winning rate of the variable winning ball device 50 itself can be easily adjusted by adjusting the adjustment mechanism 85 without relying on the adjustment mechanism 85, and the specific winning opening formed inside the variable winning ball device 50 can be easily adjusted. The winning rate for 61 can also be adjusted.

Next, with reference to FIGS. 4 to 8, an embodiment (second embodiment) in which the winning rate of the variable winning ball device is controlled by different adjusting means will be described.

In this second embodiment, a variable winning ball device 100 having almost the same structure as the variable winning ball device 50 shown in the first embodiment is applied. For this reason, the same components as in the first embodiment in the variable prize winning ball device 100 shown in FIGS. 4 and 5 are given the same reference numerals, and the explanation thereof will be omitted. Further, the constituent elements different from the first embodiment are the fifth
Movable member drive solenoids 101a, 10 shown in the figure
1b and the associated stopper solenoid 106 are provided. Therefore, the movable member drive solenoids 101a, 101b and the stopper solenoid 10 will be described below.
The configuration of No. 6 will be explained.

The actuating members 102a, 102b fixed to the plungers of the movable member drive solenoids 101a, 101b (however, 101a is not shown) have a contact piece 10 at their tips.
3a, 103b, and its contact piece portion 103a,
103b passes through the solenoid mounting plate 810 operating member guide elongated hole 82b and projects forward. In addition, return springs 104a and 104b are hooked between the lower end of the operating member 102a102b and a locking piece 105 bent at the lower end of the solenoid mounting plate 81, and the movable member drive solenoids 101a and 101b are in a de-energized state. At this time, the movable members 63a and 63b are kept in a closed state.

On the other hand, the stopper solenoid 106
A stopper 111 is connected to the plunger 107 via a connecting member 109. This stopper 111 is pivotably supported around a support shaft 113, and has an upper end that supports the actuating member 102.
It has an engaging piece 112 that engages with the abutting pieces 103a and f03b of a and 102b, and its lower end is connected to the connecting member 109 by a connecting part 110. Further, a return spring 108 is provided around the plunger 107 of the stopper solenoid 106, and constantly presses the plunger 107 so that the engaging piece 112 of the stopper 111 is in the retracted position. In other words, stopper solenoid 10
6 is in a de-energized state, the engaging piece 1 of the stopper 111
12 and the contact piece portion 103a of the actuating members 102a, 102b.
.

103b so as not to engage with each other. On the other hand, the stopper solenoid 106 is excited and the stopper 111
When the movable member driving solenoid Iota, 101b is excited with the engaging piece 112 of the actuating member 102a, 102b in contact with the engaging piece 112, It prohibits the rise,
The rotational positions of the movable members 63a and 63b are in a half-open state as shown in FIG. As a matter of course, the winning rate of balls hit into the variable winning ball device 100 when the movable members 63a and 63b are fully open and the winning rate of balls hitting the variable winning ball device 100 when the movable members 63a and 63b are in the half open state. will be different.

Therefore, in order to adjust the winning rate of the variable winning ball device 100, it is necessary to energize the stopper solenoid 1.6 to set the movable members 63a, 63b to a half-open state, or to set the movable members 63a, 63b to the half-open state without energizing the stopper solenoid 106.
What is necessary is to adjust and control the appearance probability between the fully open state and the fully open state. For example, as shown in FIG. 7, by changing the probability of appearance of the half-open state and the fully open state among the 18 opening/closing cycles, the winning rate of the variable winning ball device 100 can be varied. In the time chart shown in Figure 7, 1
The opening/closing cycle is controlled so that six of the eight opening/closing cycles are in the half-open state. In this case, the excitation time T2 of the stopper solenoid 106 is the same as that of the movable member drive solenoid 101a.

It is turned on earlier than the excitation time T1 of 101b by a minute time T3 and for a long time. This is engagement piece 1
This is to ensure that the contact pieces 12 and the contact pieces 103a and 103b are engaged with each other.

By the way, the probability of appearance of the half-open state can be controlled by preparing solenoid drive data as shown in FIG. 8, for example. That is,
As solenoid drive data, prepare solenoid drive data with a total of 10 full-open data and half-open data according to each setting value (1 to 5), and prepare so that the number of full-open data differs depending on each setting value. . Therefore, the above-mentioned 1 when winning a starting prize or when winning a special prize opening 61.
One piece of data is randomly selected from zero pieces of data and stored, and the selection and storage process is performed 18 times. Then, based on the 18 stored data, the movable member 63a
, 63b may be controlled. By controlling in this way, the fully open state and the half open state appear randomly, which has the advantage that it is difficult for the player to tell whether the ball payout rate is good or bad. The data once selected is
Each time, the data is returned to light data and used for the next selection and storage process. Furthermore, since the number of fully open data is prepared differently depending on each setting value, the fully open state of the movable members 63a and 63b is most likely to appear in setting 5, which has the largest number of fully open data, even in the selection storage process described above. , in setting 1 with the least number of full-open data, the movable member 63a is the most
63b becomes difficult to fully open. Therefore, the winning rate for the variable winning ball device 100 can be adjusted according to each set value. In addition, in the above explanation, when creating solenoid drive data for opening and closing 18 times, an example was shown in which it is created every - degree, but 10 pieces of solenoid drive data are created every time the movable member drive solenoid Iota, 101b is driven. One piece of data is selected at random from the data, and the movable member drive solenoid 10 is activated based on that data.
1a, 101b and the stopper solenoid 106 may be driven and controlled. Furthermore, when creating the solenoid drive data for opening and closing 18 times, the data may be created without restoring the selected data. In this case, the number of full-open data and the number of half-open data to be prepared may be increased, and the number of full-open data may be made different depending on each set value. However, opening/closing cycle (18 opening/closing operations or 10 prizes)
The data is returned when the game ends or when there is a winning prize in the specific winning hole 61.

By the way, in order to set the above-mentioned setting values, for example, as shown in FIG. 6, a control board box 1 having an adjustment mechanism is used instead of the control board box 43 according to the first embodiment.
20 should be prepared. This control board box 120 houses a control circuit board for controlling the game, and also includes an adjustment mechanism for setting the set values.

Here, the configuration of the control board box 120 will be explained with reference to FIG. 6. This control board box 120 is
A control circuit board (not shown) including a microcomputer is housed inside a rectangular parallelepiped metal board box body 121.

Further, on one side of the board box main body 121, a wiring 122 connected to a connector (not shown) installed on the control board described above is led out, and a connector cover 123 is attached with screws so as to cover the wiring 122. Fixed. In addition, the wiring 122 is connected to the above-mentioned relay terminal board 27 and the connection terminal board (not shown) of the variable winning ball device 100.

Furthermore, an opening 124 is provided on the rear surface of the board box main body 121.
is opened, and the opening/closing lid 12 is opened so as to cover the opening 124.
5 is provided so that it can be opened and closed freely.

The opening/closing lid 125 is provided with a locking device 126, and can be opened by unlocking the locking device 126 at 1!127.

A structure for setting the set value is housed inside the opening/closing lid 125. That is, a setting switch 128 is provided for selecting a setting value. However,
The setting switch 128 is in the form of a rotary knob, so that one of the settings 1 to 5 is selected and set each time the setting switch 128 is rotated. Further, on one side of the setting switch 128, a display is provided to display the selected setting value numerically. That is, two are provided: a current setting value display 129 that displays the current setting value and a next setting value display 130 that displays the next setting value. The current setting value display 129 displays the setting value set before the setting switch 128 was operated, and the next setting value display 130 displays the setting value set after the setting switch 128 was operated. Displaying the value. The reason why the setting values before and after the operation of the setting switch 128 are displayed is that even if the setting value is changed by rotating the setting switch 128, the changed setting value will not be reflected in the game. This is to prevent erroneous operations by displaying the setting values that will continue after a certain period of time and the setting values that will be changed after the certain period of time has elapsed. Note that when the setting switch 128 is in the form of a rotary knob and has a scale as in the embodiment, the next setting value display 130 does not necessarily need to be provided.

Further, a starting number display 131 is provided below the setting switch 128. This starting number display 131 is the starting prize opening 14.15a.

15b displays the winning number of winning balls, and when reset, displays a predetermined constant number (for example, 1000) and presses the starting winning ball detection switch 2.
Each time there is a detection signal from 5, 26a, 26b, "1" is subtracted. When the display becomes "0", the next set value set by the setting switch 128 becomes effective. That is, in the case of this embodiment, until the remaining number of times (a number within 1000; a predetermined period) displayed on the start number display 131 at the time when the person in charge of the game hall operates the setting switch 128 has elapsed. The changed setting values are not reflected in the game. therefore,
The setting value set before operating the setting switch 128 is set when the remaining number of times displayed on the starting number display 131 is "
It will be maintained for a period until it reaches 0. With this configuration, even if an employee and a player collude to fraudulently operate the setting switch 128, the result will not be directly reflected in the game, so it will be understood that it is useless, and as a result, Fraud can be prevented. In addition, the above-mentioned current setting value display 129, next setting value display 130,
Also, the data displayed on the start count display 131 is backed up and stored as is even when the power is turned off, and when the power is turned on again, the data at the time when the power was turned off is displayed. This is preferable, so that even if an employee illegally turns off the power, the set value cannot be changed.

As described above, also in the second embodiment, the probability of appearance of the fully open state and the half open state of the movable members 63a and 63b can be controlled to be different depending on the set value, so that the winning rate of the variable winning ball device 100 can be changed. can be controlled, and the winning rate of the variable winning ball device 100 can be easily adjusted without relying on the conventional dowel adjustment. In addition, in this second embodiment as well, the winning rate to the specific winning hole 61 can be adjusted as in the first embodiment. This is because the movable member 63
When the balls a and 63b are in the half-open state, as shown in FIG. 4, the force of the ball P5 flowing down on the movable member 63a is large, so it goes over the protrusion 64a and hits the movable members 63a and 63b.
The ball falls downward from between the holes, collides with the obstacle member 79, and is distributed to the left and right, and there is a high possibility that the player will normally win the winning slots 62a and 62b.On the other hand, when the opening is fully open, the first
As shown in FIG. 1A of the embodiment, there is a high possibility that the ball flows down the guide plate 74 and the ball rolling plate 78 and enters the specific winning hole 61 without climbing over the protrusion 64a. therefore,
In setting 5 where there is a lot of full-open data, the winning rate to the specific winning hole 61 is high, and in setting 1 where there is little full-open data, the winning rate to the specific winning hole 61 can be suppressed low. In addition, in the above-described embodiment, the movable members 63a, 63
Although the movable positions of b are only two positions, a fully open state and a half open state, it may be configured so that it can be changed to two or more positions to enable more complicated adjustments.

In the two embodiments described above, the movable member 63a.

63b shows a variable winning ball device 50.100 that rotates around the support shafts 65a and 65b, but as a variable winning ball device, the movable member slides laterally as shown in FIGS. 9 and 10.
