Abstract

PROBLEM TO BE SOLVED: To prevent the enjoyability of a pachinko game machine from decreasing when employing a large central device. SOLUTION: In a center generator 6, a game ball entering a ball hole 40 passes through a 'warp' gutter, moves out of a 'warp' outlet 48 onto a stage 50, and is guided onto a floating surface 54. The game ball moving onto the floating surface 54 is moved toward a drop surface 56 by the inclination of the floating surface 54, but since a projecting element 60 rises and falls, the course of the game ball is irregularly varied on contact with the projecting element 60. Thus, the game ball flowing into the center generator 6, i.e., a central device, drops from the drop surface 56 through a drop cutout 30 as its course is irregularly varied. Its dropping position varies depending on whether or not it passes on the floating surface 54 after exiting the 'warp' outlet 48 and whether or not it makes contact with the projecting element 60 on the floating surface 54.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of ball and ball game machines.

[0002]

2. Description of the Related Art Generally, in a ball-and-ball game machine, a game ball which has been bounced on an upper portion of a game area flows down while changing its path in various ways. And, as the flow path of the game ball is more diverse,
The behavior of the game ball does not become monotonous, the player can always be expected to enter the ball entrance, and a high level of interest can be obtained. The flow-down path of the game ball is affected by the arrangement of game members such as an obstacle needle, a windmill, a winning device, and a passing gate. Therefore, it is not desirable that the degree of freedom in the arrangement of these game members be limited in order to cause the game balls to flow down more effectively in the game area of a limited size.

On the other hand, in the center of the game area, a central device that is larger than other game members, such as a variable display device or a sorting device commonly called a clune, is often arranged. Usually, the central device is largely involved in the establishment of a jackpot, and is a device that can be said to be the main player of the game, and the player plays the game while paying attention to the display by the central device and the course of the game ball inside the device. I have. For this reason, a large central device with excellent visibility has been demanded.

[0004]

However, when a large central device is employed, the area occupied by the central device in the game area increases, and the arrangement of game members other than the central device is greatly restricted. For example, if the central device is enlarged, the left and right game areas of the central device are narrowed, and a ball entrance or a windmill is arranged in the narrowed game region,
It becomes difficult to make various changes in the flow path of the game ball around these game members, and the behavior of the game ball tends to be monotonous. Further, when the entrance is arranged above the game area (for example, immediately above the central device), the flow path of the game ball entering the entrance is short, so that the entrance is located below the game area. It is easier to predict the flow path than in a certain case, and a highly skilled player can aim at the entrance. In other words, an increase in the size of the central device has led to a monotonous downflow of the game balls, which may impair the interest of the game.

[0005] It is an object of the present invention to prevent a reduction in the taste when a large central device is employed.

[0006]

Means for Solving the Problems and Effects of the Invention In order to solve the above-mentioned problems, a ball game machine of the present invention comprises a game board having a game area formed by a game area partition member and having a game ball flow down. In the game board, an outer portion which is arranged at a substantially central portion of the game area and has a horizontal dimension smaller than the vertical dimension among horizontal dimensions and vertical dimensions between the game area partition member and the game area partition member. A central device, a guide portion provided in the game area above the central device, and an incoming ball including a plurality of entrances and gathered in an area below one half of the gaming area in the vertical direction. A group of ports, wherein the central device is formed in at least one of an upper portion, a left side portion, and a right side portion, and is bent at at least one place to guide the game ball to a predetermined position; A ball socket communicating with the gutter; A ball-moving portion for causing the game ball guided by the gutter to flow once and then flow down, and a course changing member formed in the ball-moving portion and capable of changing the course of the game ball, wherein the guide portion is Having an introduction port through which the game ball can pass, introducing the game ball from the introduction port, and restricting the flow of the game ball to the game area on the left and right sides of the central device, It is characterized in that the probability that a game ball is introduced into the ball socket is increased.

According to such a ball game machine, the central device has a guiding gutter for guiding the game ball to a predetermined position, and the guiding gutter is provided on at least one of the upper portion, the left portion, and the right portion of the central device. Since the communicating ball port is opened, the game ball is introduced into the ball port, from there into the guiding gutter, and guided to a predetermined position. Therefore, it is possible to guide the game balls to the central device, and it is possible to set various flowing modes of the game balls in the central device. Also, in the game area, a guide portion is provided for guiding the game ball to flow down to the ball receiving port, so that the game ball is prevented from escaping to both sides of the central device, for example, the performance of the game ball launching device is improved. The number of game balls entering the central device can be increased irrespective of the variation or the skill of the player, and the behavior of the game balls can be prevented from being monotonous by giving the behavior of the game balls a variety. Further, in the ball playing section, since a course changing member capable of changing the course of the game ball is provided, the flow-down mode (progress mode) of the game ball in the central device is more varied, and the player is provided with It is possible to give a higher interest. Further, in the present invention, the central device has an outer portion in which the horizontal dimension is smaller than the vertical dimension, out of the horizontal dimension and the vertical dimension between the game area defining member, It is possible to secure a large space in the lateral direction of the gaming machine, and it is also possible to secure a large space for the ball play portion of the central device, and it is possible to design a course changing member in various modes.

The above-mentioned predetermined position may be, for example, a lower part or a bottom part of a central device. The guide gutter can be a warp gutter, and the ball socket can be a warp gutter entrance. The guiding gutter can be exemplified by a cylindrical structure capable of guiding a game ball, which can flow a game ball from top to bottom, but is not limited thereto, and a passage through which a game ball can be guided is formed. This means that it is a member.
Further, it is preferable that the guide portion is constituted by an obstacle nail, but the present invention is not limited to this. The various possible components can be employed alone or in any combination.

The central device is a device which is disposed substantially at the center of the game area and has external dimensions which restrict the placement of the entrance to at least one of the game area above, on the left side, and on the right side. Any device may be used as long as it is involved in the progress of a ball game, and its function or use is not particularly limited. Specific examples of such a central device include a variable display device, a sorting prize device typified by a clune, a variable prize device, and the like. The outer peripheral shape may be appropriately set, and examples thereof include a horizontally long, vertically long, square, round, oval, and elliptical shape. For example, in the case of a horizontally long central device in which the areas of the left and right game areas of the central device are restricted, it is possible to mount a large-sized central device that makes full use of the game region and improve visibility. be able to.

Further, since the central device has a game ball moving area in which the game balls entering from outside move, the central apparatus moves the game balls flowing from above or from the side in the game ball moving area and then moves downward. Can be dropped. Therefore, it is possible to contribute to diversification of the flow path of the game ball. Moreover,
Since the course changing member changes the course of the game ball in the game ball movement area according to its own behavior, the course of the game ball in the central device is diversified, and the position at which the game ball exits the game ball movement area is also diversified. be able to. Thus, it is possible to prevent a decrease in the taste due to the monotonous flow of the game balls.

The course changing member may be a passive structure that rotates or swings by the load of the game ball, for example. However, if a driving mechanism is provided to change the position of the course changing member actively, The modes can be further diversified, and the taste can be improved. The course changing member can specifically constitute the course changing member by the protruding and retracting body. In this case, the course of the game ball changes in various directions by contacting the protruding and protruding body. In addition, the course change member,
It can also be constituted by a movable member that can reciprocate along the longitudinal direction. In this case, the game ball changes its course in various directions by contacting the movable member, and the course is changed for the movable member to move. Will be uneven and varied. Further, the course changing member may include at least a rotating body incorporating a magnet, and a discharge position regulating member for restricting a flowing position of the game ball. In this case, since the effect of the game ball is attracted by the magnet and the effect of the release position regulating member are complicatedly involved,
An unpredictable flow-down mode (progressing mode) is taken.

The game area partition member includes a guide rail for guiding a game ball fired on the game board surface to the game area, and a return rubber for reflecting the game ball reaching the game area to a substantially central portion thereof. And a decorative member formed on the game board surface.

In the present invention, when the central device has a horizontally long shape at least on the front side, for example, since the central device has a horizontally long shape, it is possible to restrict the left and right game areas of the central device. It is possible to realize a ball and ball game machine using a large central device that makes the most of the game area. In addition, when such a central device is a variable display device, it becomes possible to improve the visibility and the interest by combining the symbol display and the game mode of the game ball, and the like. It is possible to further enhance the taste of the game in the improved ball and ball game machine.

As shown in FIGS. 4 to 8, slopes 52 are provided at the left and right ends of a stage 50 (game ball moving area) corresponding to the bottom of the frame 38. The slope 52 is provided with a partition 52a, and the partition 52a and the display window 38 are provided.
A space between the guide passage 52a and the guide passage 52a is a guide passage 52b corresponding to the warp outlet 48.

Also, as shown in FIGS.
In the center of the center 0, there is provided a loosely inclined floating surface 54 in which the display window 38a side is high and the base plate 30 side is low.
As shown in FIG. 6, between the floating surface 54 and the base plate 30, a falling surface 5 having a slope higher on the floating surface 54 side and lower on the base plate 30 side.
6 are provided. The base plate 30 is provided with a drop notch 30 a corresponding to the drop surface 56.

As shown in FIGS. 4 to 8, on the floating surface 54,
A total of nine guide holes 58 are provided, five in one row on the display window 38a side and four in one row on the base plate 30 side. In each of the guide holes 58, a projecting and retracting body 60 is inserted. FIG.
As shown in FIGS. 7 and 8, the protruding and retracting body 60 is provided with a substantially spherical portion 60a located on the upper side, a small hemispherical portion 60b suspended downward, and a retaining member extending in the radial direction below the mostly spherical portion 60a. Protrusion 60

Is prevented from coming out of the guide hole 58 upward.

A drive mechanism housing 62 is provided below the floating surface 54.
A drive mechanism 64 for driving the projecting and retracting body 60 to move up and down is accommodated therein. Further, a motor 66 serving as a drive source is mounted below the drive mechanism housing portion 62. A rotating plate 70 is attached to an output shaft 68 of the motor 66, and an engaging pin 72 is attached to the rotating plate 70 so as to be shifted from the output shaft 68. A slide plate 76 supported by a slide guide 74 and capable of reciprocating along the slide guide 74 is disposed above the rotary plate 70. The upper end of the engaging pin 72 is

a is provided. Also, as shown in FIG. 9, since the inner peripheral shape of the joint portion 78 is rectangular, when the engagement pin 72 makes a circular motion by the operation of the motor 66, the slide plate 76
Reciprocates along the slide guide 74. Then, by the reciprocating movement of the slide plate 76, the contact position between the small hemisphere portion 60b of the projecting and retracting body 60 and the inclined surfaces 80a and 82a changes, and the projecting and retracting body 60 moves up and down accordingly. Since the directions of the inclined surfaces 80a and 82a are opposite, when the protruding body 60 on the display window 38a side rises, the protruding body 60 on the base plate 30 side descends and the display window 38a.
When the body 60 on the side of the base plate descends, the body 60 on the side of the base plate 30 rises.

In the center role 6 having such a configuration, a game ball that has entered the entrance 40 of the interior decoration 32 during execution of a pachinko game passes through the warp gutter 46 and flows out onto the stage 50 from the warp outlet 48. I do. Most of the game balls flowing out of the warp exit 48 are guided onto the playing surface 54 by the guide passage 52b. Also, some of the game balls flowing out of the warp outlet 48 are separated from the guide passage 52b and reach the slope 52 to the play surface 54, while others reach the fall surface 56 without passing through the play surface 54. . The game ball that has reached the falling surface 56 falls from the drop notch 30a.

The game ball that has moved onto the playing surface 54 moves toward the falling surface 56 due to the inclination of the playing surface 54. At this time, since the projecting body 60 is moved up and down, contact with the projecting body 60 occurs. Makes the course change irregularly. Therefore,
The game ball that has flowed into the center role item 6, that is, the central device 5, has its course changed irregularly, and falls from the falling surface 56 through the drop notch 30a. The drop position is
It differs depending on whether or not it passes through the floating surface 54 after exiting the warp outlet 48, and variously depending on the degree of contact or non-contact with the projecting and retracting body 60 on the floating surface 54.

Below the notch 30a, there are shown FIGS.
Since the start winning device 7 is arranged as shown in FIG. 7 and the possibility of a special game is generated by winning in the start winning device 7, it is determined from which part of the drop notch 30a to fall.
Very important. Since the falling position is determined by the path of the game ball in the central device 5, it is possible to enhance the interest of the game by changing the course of the game ball in a complicated manner as described above.

Next, the dimensions of the central device 5 and the dimensional relationship between the central device 5 and the game board 2 will be described with reference to FIG. FIG.
As shown in the figure, the width of the center-item left ball passing area, which is the width of the left and right game areas 4 of the center item 6 of the central device 5, is W1 = 32.5 mm, and the width of the center item right ball passing area is W4. = 33.2 mm, and the center part 6
Guide gutter ball socket area of upper game area 4 Height H1 = 70m
m.

If it is assumed that the entrances are located on the left and right sides of the central device 5, for example, near the left and right ball passing areas of the center role,
Normally, the ball entrance of a single item has a ball receiving part width of about 20 mm, and the total width of the ball entrance is about 40 mm including the mounting base,
It is difficult to set the entrance. Therefore, even if the ball entrance is attached from the back side of the game board 2 and only the ball reception part of the ball entrance protrudes from the front side of the game board 2, the width of the ball reception part is 2
Since it is about 0 mm, the remaining space is about 13 mm. In the end, although it is possible to arrange obstacle nails and entrance holes, it is difficult to let game balls flow down.

Although it is possible to set a ball entrance in the game area 4 above the central device 5, a gutter for guiding a game ball entering the ball entrance downward on the back side of the game board 2 is provided at the center. The device 5 must be arranged so as to avoid the back parts (such as the case of the display device 5a). Although the device 5 can be installed, it may not be structurally preferable.

On the other hand, in order to secure the degree of freedom in the arrangement of the entrance and attacker below the game area 4, the central device 5 is required.
Is preferably located above the game area 4 as much as possible. If the central device 5 is further arranged above, the effective space below the game area 4 is enlarged, but the entrance cannot be arranged above. Holds. Therefore, a design considering such a relationship is desirable.

Further, in FIG. 3, a plurality of obstacle nails are arranged above the center accessory 6, and the entrance area width W
The game ball that has fallen within the lateral width of No. 2 is configured to easily enter the ball entrance 40 (see FIG. 2). The game ball that has entered the entrance 40 flows down onto the stage 50 via the warp gutter 46 (see FIG. 6), and the starting winning device 7
(See FIG. 1).
The likelihood of entering a ball increases.

By the way, in the case of the conventional ball game machine, in order to achieve the winning in the starting winning opening, the player adjusts the firing force of the game ball launching device to determine a position where the ball can easily enter the starting winning opening. Shooting a game ball aiming. However, even if the position of the firing handle 22 is adjusted so that the firing force of the game ball firing device is constant, there is a possibility that the firing force may be contrary to the adjustment due to a variation in the firing force. For this reason, the game ball does not necessarily fly to the intended position, and is shot to a position where the possibility of entering the ball winning the starting winning opening is low,
There is a risk that the player will be disappointed.

On the other hand, in the pachinko machine 1 of the present embodiment, if the game ball is launched into the game area 4 within the relatively wide entrance opening area width W2, the game ball is released as described above. From the warp gutter 46 to the stage 50, the starting winning device 7
Falls from the drop notch 30a above, so that the possibility of entering the start winning device 7 is increased. Therefore, it is extremely unlikely that variations in the launching power of the game ball launching device, the skill of the player, and the like will affect the entry into the starting winning device 7.

Next, the dimensional relationship of the game board 2 will be described. Approximately 12 when the area of the game area 4 is measured (on CAD)
3,988 mm ² . The vertical dimension of the game area 4 (L = 39
6mm) is about 123,163m
m ^2, which is almost equal to the result of the area measurement. In this example, the area of the game area 4 is calculated by approximating the area to the back circle of the diameter L. This dimension L is a vertical distance from the lowermost point to the uppermost point of the game area 4. The area of each member in the present embodiment is as follows.

Center part 6 (for 10 inches) Approx. 58,463 mm ² Center part (for 8 inches) Approx. 37,416 mm ² 10 inch screen of liquid crystal display panel 5 b Approx. 30,426 mm ² Center for 8 inches The area of the accessory (not shown) is
It is simply calculated by multiplying the scale of the illustrated center role 6 of the embodiment by 0.8 (area ratio 0.64). However, the approximate dimensions of each part of the warp gutter 46 are naturally determined based on the diameter of the game ball and the thickness of the gutter wall, and even if an 8-inch display body is employed, a dimension through which the game ball can pass must be secured. Therefore, it is considered that the vertical and horizontal dimensions of each gutter of the center role and the outer dimensions of the ornaments covering the gutter are not much different from those of the case of 10 inches. Therefore, it is considered that the actual area of the center role when the 8-inch display is actually used is actually larger than the calculated value of the 8-inch center role described above.

From the above, in the case of the central device 5 adopting the 10-inch liquid crystal display panel 5b and the center role 6 (for 10-inch), the ratio of the area of the central device 5 to the game area 4 at that time is as follows. It becomes 47%. Also, when an 8-inch liquid crystal display panel is adopted using the center role (for 8 inches), the ratio of the area of the central device 5 to the game area 4 at that time is 30%. 10-inch LCD panel 5
When b is adopted independently without using the center role 6, the area of the central device 5 is equal to the area of the liquid crystal display panel 5b,
At that time, the ratio of the area of the central device 5 to the game area 4 is 25% (about 4: 1), and the area of the central device 5 is the minimum area. As described above, the central device 5 includes the game area 4
Occupies approximately 25% (1/4) or more, preferably approximately 30% or more, and particularly preferably approximately 47% or more of the surface area of the polymer.

When the 8-inch display body is used alone, the area ratio is about 16%, and it is considered that the restrictions when setting the entrance are relaxed. Here, the area means the projected area. In the present embodiment, the entrance groups N are collectively arranged below the central device 5, avoiding the central device 5. That is, the height of the area where the entrance group N is arranged is the game area 4
From the bottom of the to the lower end of the center role 6,
The left and right sides of the area to be arranged must be full. A ball entrance may be additionally provided on the stage 54 of the center accessory 6.

In this embodiment, the liquid crystal display panel 5b having a 10-inch screen and the center part 6 adapted to the liquid crystal display panel 5b are used. Thus, the area occupied by the central device 5 decreases, and the room left, right, or above the central device 5 increases.

For example, when a display body of about 8 inches, which is slightly larger than the size (4 to 6 inches) that is generally adopted, and the center object 6 is simply reduced in size, the center member The width of the object left and right ball passing area width W1 (the area in which the game ball can flow down) is calculated based on the difference between the screen width dimensions shown in FIG. 3 (the width W15-8 inches of the liquid crystal display panel 5b of the 10-inch screen). Screen width of liquid crystal display panel W16) / 2 = (207.4-165.9) / 2 = 20.
It is calculated to be 75 mm and increases by about 20 mm on each side.
Therefore, since the width W1 of the center role left ball passing area and the width W4 of the center role right ball passing area of the central device 5 of the 10-inch screen size in this embodiment are about 33 mm,
When the screen size is 8 inches, the width of each of the left and right regions is about 53 mm (= 33 + 20).

When a single ball entrance (for example, a small one having a width of about 20 mm) is arranged in this area, about 16.5 mm (= (53−20) / 2) is provided on both sides of the entrance. Room can be secured, but since the diameter of the game ball is 1 lmm,
The game ball that has deviated from the entrance is 2.75 mm (= (1
The route can be changed only by 6.5-11) / 2). For this reason, a game ball that has deviated from the entrance can only flow down almost immediately below, and it is difficult to give a sufficient change to the behavior of the game ball to enhance the interest.

Further, since the total number of entrances is specified by the game rules and the total number of entrances must be equal to or greater than the specified number, the number of entrances can be easily reduced as the central device 5 becomes larger. Cannot be reduced to Therefore, in order to make the central device 5 larger than the current state without reducing the total number of entrances, it is essential to solve the problem of the arrangement of entrances. For this reason, the entrances are not set in the center-accompaniment left and right ball speed areas, and the entrances N are arranged in the above-described area in a concentrated manner.

Further, according to the current game rules, the total number of ball entrances (the total number of winning prizes) is specified to be 5 or more in a normal game state in which the movable accessory does not operate. The number must be at least one-third (rounded down). In this embodiment, the total number of entrances (total number of winnings)
5 and one starting port (start winning device 7), which satisfies this rule. When the total number of entrance ports (total number of winning ports) is larger than that, it may be necessary to appropriately change the arrangement of the entrance ports and the like.

The dimensional relationship between the central device 5 and the surrounding game area 4 will be described with reference to FIG. The vertical distance H2 from the vertex of the central device 5 to the vertex of the game area 4 is 67.
0 mm, the vertical distance H3 from the apex of the central device 5 to the apex center nail is 34.0 mm, and the height H4 of the center accessory 6 is 2
It is set to 21.0 mm. Also, the entrance opening area width W

m, the inlet width W5 is 13.5 mm, the horizontal distance W6 of the inlet upper nail is 58.7 mm, and the width W8 of the area slightly above the width W1 of the center item left ball passage area W3 is 33.3 mm. Is set to 31.6 mm. The left and right regions where the windmill 29 (see FIG. 2) is arranged have a left width W10 of 46.5 mm and a right width W11 of 45.9.
mm. The expanded maximum width W12 of the start winning device 7 is 48.5 mm, and the normal width W13 is 14.0 mm.
Is set to Further, from the horizontal line passing through the lowermost point of the first rail member 3a, the uppermost part of the center item 6, the horizontal line at the center of the liquid crystal display panel 5b, the top of the starting winning device, the horizontal line passing through the lowermost point of the center item 6, A horizontal line indicating the height of the center of the attacker 8, the top point of the entrance 12 and the vertical distance H5, H6, H7, H8, H9, H10, to the top point of the entrance 11

Is 146.7 mm, the width W15 is 207.4 mm, the height of the screen of the 8-inch liquid crystal display panel is set to 117.3 mm, and the width of W16 is set to 165.9 mm.

Since the dimensions are as described above,
The central device 5 having a large external size is arranged almost at the center of the game area 4 to such an extent that the placement of the entrance to at least one of the left and right game areas 4 is restricted. In the lower half area, particularly below the lower end of the central device 5, the entrances can be arranged intensively.

Then, inside the central device 5, the course of the game ball is changed in a complicated manner by the stage 50, the play surface 54, and the projecting and retracting body 60, and then the ball is dropped from the notch 30a to above the starting winning device 7. Therefore, with the pachinko machine 1 using the large central device 5 having good visibility, it is possible to prevent a decrease in the interest due to the monotonous flow of the game balls.
(Modification 1) In the first embodiment, the projecting and retracting bodies 60 are substantially uniformly distributed on the floating surface 54. However, as shown in FIG. You can also.

In the modified example 1 (FIG. 10), all the protruding bodies 60 protrude and retract at the same timing. At the time of immersion, the game ball easily flows down from the playing surface 54 to the falling surface 56, and at the time of projecting, it is difficult to reach the falling surface 56. (Modification 2) Alternatively, as shown in FIG. 11, a sparse distributed arrangement area of the projecting and retracting body 60 and a concentrated arrangement area where the arrangement density of the projecting and retracting body 60 is high can be provided.

In the modified example 2 (FIG. 11), the concentrated arrangement area is the same as that of the modified example 1. However, depending on the distributed arrangement area, there are cases where the game balls are easy to approach the concentrated arrangement area and difficult to approach. The same effects as in the first embodiment can be obtained with the configurations exemplified in the first and second modifications.

In the center role item 6a, the game ball that entered the entrance 40 of the interior decoration 32 during the execution of the pachinko game is:
The stage 50 passes through the warp gutter 46 and from the warp exit 48
a. Most of the game balls flowing out of the warp exit 48 are guided to the play surface 54a by the guide passage 52b. In addition, some of the game balls flowing out of the warp outlet 48 deviate from the guide passage 52b and from the slope 52 to the play surface 5
Some reach the upper surface 4a, while others reach the falling surface 56 without passing through the floating surface 54a. The game ball that has reached the falling surface 56 falls from the drop notch 30a.

On the floating surface 54a, the first movable member 92 and the second movable member 94 reciprocate left and right. Idling surface 5
The game ball that has moved to the rear side of the first movable member 92 on 4a collides with any of the convex portions 92a of the first movable member 92, and is hit by the convex portion 92a. The course changes while sliding or rolling,
After that, most of the game balls enter the concave portions 92b, 92c of the first movable member 92, and the concave portions 92b, 9c.
The first movable member 92 is moved to the near side by the inclination of 2c.

Note that the width of the central concave portion 92c is different from that of the other concave portions 9c.
Since it is wider than the width of 2b, it can be said that the game balls can be easily received, and that many game balls pass through the central concave portion 92c. The game sphere that has separated from the first movable member 92 or has flowed directly between the first movable member 92 and the second movable member 94 from the slope 52 side has one of the convex portions 9 of the second movable member 94.

Embodiment 3 This embodiment is an example in which a drum containing a magnet is used as a course changing member. Note that the overall structure of the pachinko machine and the structure of the game board including the arrangement of the central device and the winning port are the same as those in the first embodiment, and thus illustration and description are omitted. In addition, since the structure of many parts of the central device is common to that of the central device of the first embodiment, the same reference numerals as those of the first embodiment are used for the same components, and description thereof is omitted.

As shown in FIGS. 16 to 19, on the floating surface 54b of the center part 6b of the central device 5B of this embodiment,
Discharge position regulating members 110 and 112 that are symmetric with each other are provided. The release position regulating member 110 is composed of an L-shaped wall 110a and a floor 110b inside the wall 110a.
The inside of the horizontal portion of a is tapered, and the floor 110b is slightly inclined such that the left rear corner is high and the right front corner is low. The discharge position regulating member 112 also includes an inverted L-shaped wall 112a and a floor 112b inside the wall 112a, and has a shape that is a mirror image of the discharge position restricting member 110. Wall 110a
The distance between the front end of the wall 112a is a distance through which a game ball can pass.

Behind the release position regulating members 110 and 112, a hole 114 is provided in the floating surface 54b, and about one-fourth of the hole 114 is formed in the hole 114.
The rotating body 116 is disposed so as to protrude above b. Further, on the left and right sides of the rotating body 116, the side convex portions 11 in the shape of a semi-cylindrical shape are provided.
8, 120 are provided in such a manner as to protrude from the floating surface 54b.

As shown in FIG. 18, both ends of the rotating body 116 are covered with side projections 118 and 120, and one end of the rotating body 116 has side projections 118.
It is rotatably supported by a support pin 124 inserted through a support boss 122 provided below. An output shaft 128 of a motor 126 housed below the side protrusion 120 is fitted to a connection boss 116 a provided at the other end of the rotating body 116. Note that the output shaft 128 and the support pin 124 are substantially concentric.

Further, as shown in FIGS. 17 and 18,
A plurality of magnets 130 are mounted inside the rotating body 116, and the magnets can attract game balls to the surface of the rotating body 116. In the present embodiment, the rotary body 116 is provided with a suction hole smaller in diameter than the magnet 130, but it is preferable from the appearance that the suction hole is covered with a decorative seal or the like.

With such a configuration, when the motor 126 is operated, the rotating body 116 can be rotated.
At that time, the game balls can be transported by being attracted to the surface of the rotating body 116 by the magnets 130. In the case of the present embodiment, during operation of the pachinko machine, the rotating body 116
The upper side of 4b is rotated in the direction from the back side of the floating surface 54b toward the front side.

For this reason, the game balls adsorbed and conveyed on the surface of the rotating body 116 contact the floors 110b, 112b of the release position regulating members 110, 112 when reaching the near side, whereby the rotating body 116 The rotation of the magnet 130 cannot be followed. When the rotation of the rotating body 116 continues, the distance between the game ball stopped on the floors 110b and 112b and the magnet 130 increases, the attraction force of the magnet 130 weakens, and the game ball separates from the rotating body 116. Rotating fuselage 1
The game ball detached from 16 is guided by the inclination of the floors 110b and 112b and the tapered surfaces of the walls 110a and 112a, falls on the falling surface 56 from between the release position regulating members 110 and 112, and falls from the drop notch 30a. . Further, the other part is linearly guided by the guide recess and is discharged to the falling surface 56 from the center between the two discharge position regulating members 110 and 112.

In this center role 6b, the game ball that has entered the entrance 40 of the interior decoration 32 during the execution of the pachinko game is:
The stage 50 passes through the warp gutter 46 and from the warp exit 48
Most of the game balls that have flowed out onto the a and flown out from the warp outlet 48 are guided onto the play surface 54b by the guide passage 52b. In addition, some of the game balls flowing out of the warp outlet 48 deviate from the guide passage 52b and from the slope 52 to the play surface 5
4b, while others reach the falling surface 56 without passing through the floating surface 54b. The game ball that has reached the falling surface 56 falls from the drop notch 30a. Some of the game balls guided to the play surface 54b by the guide passage 52b move toward the play surface 54b by collision with the side convex portions 118 and 120 and reach the falling surface 56. Moving along the traveling direction of the passage 52b, the rotating body 1
Some reach the back of the sixteen. Such a game ball is carried from the back side to the front side with the rotation of the rotating body 116 as described above, is separated from the rotating body 116 by the release position regulating members 110 and 112, falls on the falling surface 56, and falls. It falls from the notch 30a.

As described above, the game ball that has flowed into the center role object 6b has its course changed irregularly, and falls from the falling surface 56 through the drop notch 30a. The drop position differs depending on whether or not to pass through the guide passage 52b after exiting the warp outlet 48, and also depending on whether or not to advance from the guide passage 52b to the rear side of the rotating body 116. As shown in FIGS. 1, 2, and 5, a start winning device 7 is disposed below the drop notch 30a, and the possibility of a special game is generated by winning the start winning device 7.
It is extremely important which part of the drop notch 30a falls. And the falling position is the center item 6
Since it is influenced by the path of the game ball in b, the interest of the game can be enhanced by changing the course of the game ball in a complicated manner as described above. In particular, when being sucked and conveyed by the rotating body 116, it falls from almost the center of the drop notch 30a, that is, directly above the starting winning device 7, so that
The possibility of winning in the start winning device 7 is increased, and the interest of the game can be enhanced.

The embodiments of the present invention have been described with reference to the embodiments. However, the present invention is not limited to such embodiments, and it can be variously implemented without departing from the gist of the present invention. Needless to say.
