However, in the open / close type winning device as described above, especially when the opening / closing plate is opened and shortened for a plurality of times, the physical noise accompanying the opening / closing of the opening / closing plate is generated. There was a problem that it occurred. In addition, the rotating body as shown in Patent Document 2 is not suitable for use in a winning device such as a big prize opening because there is no problem of noise but the number of game balls to be received is limited.
Accordingly, the present invention has been made paying attention to the above-mentioned circumstances, and the invention according to claim 1 does not generate noise during operation, and allows a plurality of game balls to be awarded together. An object is to provide a variable prize winning device. In addition to the above object, the invention described in claims 2 to 4 has an object of providing a variable winning device for a ball game machine capable of varying the winning rate even if the opening time is the same. .

The features of the present invention will be described below using the embodiment of the invention shown in the drawings. In addition, the code | symbol in parenthesis shows the code | symbol used in embodiment of invention, and does not limit the technical scope of this invention.
(Feature point)
(Claim 1)
The invention described in claim 1 is characterized by the following points.
That is, the invention described in claim 1 is a ball game machine provided in a game area (1a) of a game board (1) of a game machine in which a front surface is covered with a transparent plate (glass frame 3A) and a game ball is launched. A variable winning device, a rotating body (20) capable of closing the openings (1A, 11) formed on the surface of the game board (1), and a rotational drive for rotating the rotating body (20) And at least a device (30). The rotating body (20) is rotatably supported on a rotating shaft (22) provided in the vicinity of the opening (11) in parallel and horizontally with the board surface of the game board (1), and the opening ( It can be rotated inside 11). Further, when the rotating body (20) is in an initial position where the opening (11) is closed, a game ball can flow between the rotating body (20) and the transparent plate (3A). In addition, when the rotation drive device (30) is rotated in any direction from the initial position by the operation of the rotation drive device (30), a part of the rotating body (20) is released from the opening (11) to the game board (1). The projection part is formed so as not to interfere with the transparent plate (3A). Then, a game ball flowing down from the projecting portion of the rotating body (20) protruding from the opening (11) to the front side of the board surface of the game board (1) is received, and the game ball is received by the rotating body. It is possible to guide into the opening (11) from a gap formed between (20) and the upper edge of the opening (11).

Here, the game board (1) is a plate-like member with a nail, a windmill and various objects arranged on the surface, and a game area (1a) where the game ball collides with the nail or the like and falls while changing its direction. It has.
The rotating body (20) is attached so as to rotate in the front-rear direction when viewed from the front, and the shape thereof is not limited. For example, it can be a plate-shaped member or a bowl-shaped member. Further, the rotating body (20) may be able to close the entire opening (11), or may be able to close a part of the opening (11).
`` Near the opening (11) '' includes the periphery and inner periphery of the opening (11), and the rotation shaft (22) may be provided directly on the game board, or on the game board (1). You may provide in the other member (storage case 10) accommodated inside the formed opening part (1A).

The rotation drive device (30) may be a drive motor (31) whose drive shaft is attached to or connected to the rotation shaft (22), and may include a connecting means such as a gear or a belt. Further, the rotation drive device (30) may be able to rotate the rotating body (20) in the direction opposite to the one direction.
Here, “when in the initial position, the game ball can flow between the rotating body (20) and the transparent plate (3A)” means that the front portion of the rotating body (20) in the initial position is the board surface. Including a case where there is a gap through which the game ball can pass even if there is a protruding portion, and the protruding portion of the rotating body (20) prevents the flow of the game ball directly under the game ball, This includes cases where game balls spill from the side without staying there.

(Function)
In the present invention, when the rotating body (20) is in the initial position, the game ball flowing down the game area (1a) is not guided into the opening (11). Even when the rotating body (20) closes only a part of the opening (11), the game ball is not guided into the opening (11). Then, by operating the rotation driving device (30) according to the gaming state, when the rotating body (20) rotates in any direction, a part of the rotating body (20) protrudes forward from the board surface. , It will be possible to receive the game balls that flow down. The game ball received by the rotating body (20) is guided to the inside of the opening (11), and this game ball is detected by a predetermined ball detection sensor and treated as a winning ball. Depending on the shape and direction of rotation of the rotator (20), even if a part of the rotator (20) protrudes forward from the board surface, the game ball cannot be received or the received game ball is opened to the opening. (11) There are cases where it cannot be guided inside.

While the rotating body (20) is rotating, as described above, the winning state in which the game ball can be guided into the opening (11) and the game ball cannot be guided into the opening (11) are not allowed. The state will be repeated. Then, one rotation of the rotating body (20) at a predetermined speed can be set as a so-called one round in which the opening (11) is opened for a predetermined time.
According to the present invention, since the rotating body (20) is rotated in the front-rear direction to guide the game ball to the winning opening, if the lateral width of the rotating body (20) is increased, a plurality of game balls can be taken in at a time. . In addition, since there is no fluttering noise that accompanies the opening and closing of the members during the rotational movement, there is no harsh feeling during the game.

(Claim 2)
According to a second aspect of the present invention, in addition to the feature of the first aspect of the present invention, the rotary drive device (30) is configured such that the rotary body (20) is positioned forward of the rotary shaft (22). The rotating body (20) can be rotated in the forward rotation direction and can be rotated in the reverse rotation direction in which the upper side of the rotating shaft (22) moves backward, and the rotating body (20) is rotated in the forward rotation direction. It is characterized in that the game ball is more likely to be guided into the opening (11) when rotating in the reverse direction than when rotating.
Here, “forward rotation direction” and “reverse rotation direction” are given names for convenience in order to clarify the difference in relative rotation direction, and the direction in which the upper side of the rotation shaft (22) moves forward. May be the reverse direction. In this case, the possibility of guiding the game ball into the opening (11) is higher when the rotating body (20) rotates in the forward rotation direction than when it rotates in the reverse rotation direction. . This is because when the rotating body (20) is rotated in the direction in which the upper side of the rotating shaft (22) moves backward, the rotating shaft of the rotating body (20) is compared to the case of rotating in the opposite direction. This is because the game ball is easily received and guided into the opening (11) as much as the lower side of (22) rises forward.

According to the present invention, by selectively using the forward / reverse rotation of the rotating body (20) depending on the game state, the winning rate can be changed even in the special game state with the same number of rounds.
(Claim 3)

As shown in FIG. 2, the game board 1 is a plate member having a board surface on which a flow regulation regulation member such as a windmill or a plurality of nails for regulating the flow direction of the game ball is provided and the flow direction is changed. Around the board surface, there is provided a guide rail 60 for guiding the game ball launched from the ball launching device by operating the handle 5 to the game area 1a.

  In the center of the board surface of the game board 1, there is provided a variable display section 40 for performing various displays such as characters, figures and moving pictures using a liquid crystal display device and a rotating reel. Also, below the variable display section 40, there is a start winning opening 50 where a special symbol lottery is performed in the event of winning a prize. Below the starting winning opening 50 is a big winning opening that is opened when a big win game is won Each mouth 8 is provided. On both sides of the start winning opening 50, a general winning opening 100 is provided, which is a winning opening that only pays out a prize ball by winning. At the center of the lowermost end of the game area 1a of the game board 1, there is provided an out port 70 for discharging game balls that have not won any prize opening to the back of the game board 1 outside the game area 1a. ing.

Further, a gate 90 is provided at the left end and slightly above the gaming board 1 where a normal symbol lottery is performed when a game ball passes. Above the variable display section 40, a digital display section 80 for displaying a gaming state is provided.
Here, the periphery of the variable display section 40 is surrounded by a peripheral wall that prevents the inflow of game balls, and the side wall of the peripheral wall is not particularly shown, but is one of the game balls that flow down the periphery of the peripheral wall. A warp route that can take the part into the surrounding wall is provided. The game balls that have flowed in from the warp route are guided to a stage that is the bottom of the surrounding wall. A part of the game ball guided to the stage is guided to the start winning opening 50 provided below the stage.

  As shown in FIG. 2, the start winning port 50 is composed of two winning ports arranged in the vertical direction. The first start port 51 disposed on the upper side can receive a game ball guided to the stage. The second starting port 52 arranged on the lower side is provided with an electric accessory called a so-called electric chew. In normal times, the left and right movable pieces 53 constituting the electric accessory are closed, and the game ball does not enter the second start port 52 directly, but based on the lottery result of the normal symbol, the movable pieces 53 is opened for a preset time and can receive a game ball from the side. In other words, when the movable piece 53 is closed, the game ball wins only at the first start opening 51, and when the movable piece 53 is open, the game ball can win at both the upper and lower start winning openings 50.

The large winning opening 8 is a variable winning device, and in this embodiment, the opening provided on the board surface is opened and closed by the rotation of the rotating body 20 (see FIG. 4). Normally, the rotating body 20 is closed so as not to allow game balls to flow in, and when a special symbol is drawn as a result of lottery, the open state is opened so that game balls can easily flow in. In addition, opening and closing is repeated for a predetermined number of rounds determined by lottery. The detailed mechanism of the special winning opening 8 will be described later.
The digital display unit 80 is composed of a multi-digit (or 1-digit) 7-segment LED display device, and is capable of variably displaying or stopping displaying predetermined character numbers. The digital display unit 80 includes at least a special symbol display unit 81 that displays a special symbol in a variable manner and stops display, and a normal symbol display unit 82 that displays a normal symbol in a variable manner and stops.

(Operation of pachinko machine P)
An outline of the game of the pachinko gaming machine P having the above configuration will be described.
When the game ball guided to the game area 1a wins the start winning opening 50, the start winning ball detecting sensor (not shown) detects the game ball, so that an opportunity to start the variable display game with a special symbol is given. . In the case of winning at the start winning opening 50, the game ball enters the first starting opening 51 through the stage from the warp route, and the movable piece 53 of the second starting opening 52 is opened as described later. This is a case where the ball enters the starting port 52. When winning, a predetermined number of game balls are paid out to the lower plate 4.

  In the variable display game, a predetermined symbol displayed on the variable display unit 40 (decorative symbol such as a number or a pattern) and a numerical value displayed on the special symbol display unit 81 are sequentially switched to display a single numerical value. Stop display. Here, the variable display unit 40 and the special symbol display unit 81 display the variable display game corresponding to the same single lottery result almost simultaneously, and the variable display unit 40 and the special symbol display unit 81 have the same lottery. The results are displayed sequentially. In other words, the variable display on the variable display unit 40 and the variable display on the special symbol display unit 81 are performed almost simultaneously, and the winning lottery results displayed are the same. The variable display section 40 and the special symbol display section 81 have substantially the same variable display time (the start timing and stop timing of the variable display), and it is sufficient that the result of the hit error is the same, and other displays are different. It's okay. For example, the combination of the decorative symbol that is the winning combination that is stopped when the variable display game is finished may be different from the combination of the special symbol that is the winning combination.

In the special symbol variation display game, the special game state occurs when the combination of the special symbols stopped and displayed in each display area becomes a predetermined combination (predetermined stop symbol) (when it is a win). Note that the result of the hit failure is determined by a lottery performed by a control device for controlling the operation of the pachinko gaming machine P in response to the ball detection of the start winning opening 50.
Here, when the start winning ball detection sensor detects a game ball won in the start winning opening 50, the detection is stored as a special symbol start memory number within a range of an upper limit (for example, 4), and this start win When a variable display game (variable display game of both decorative symbols and special symbols) is started based on the above, a process of subtracting 1 from the special symbol start memory number is performed. This special symbol start memory number is displayed on a special symbol reservation number display unit (not shown) of the digital display unit 80.

When the special game state is entered, rotation of the rotary body 20 of the special winning opening 8 starts. The rotating body 20 is controlled to rotate a predetermined number of times (for example, 15 times) in a predetermined direction at a predetermined speed. In the present embodiment, one rotation of the rotating body 20 is referred to as one round.
In addition to the above, the special game state may be set so that the rotating body 20 is rotated only twice, or after the predetermined round, the advantageous state (the so-called probability change, normal symbol that increases the winning probability of the special symbol lottery) Is set so as to shift to a so-called short time in which the fluctuation time is shorter than the normal time and the number of lotteries per unit time is increased. These are performed by winning the symbol corresponding to each type of winning as a result of the lottery of the special symbol lottery.

On the other hand, when the game ball guided to the game area 1a passes through the gate 90, a trigger for starting the normal symbol variation display game is given based on the fact that a passing ball detection sensor (not shown) detects the game ball. In the normal symbol fluctuation display game, the numerical values displayed on the normal symbol display portion 82 of the digital display portion 80 are sequentially switched and displayed in a variable manner, and then one numerical value is stopped and displayed. A hit value is a hit. Note that the result of the hit failure is determined by a lottery performed by a control device for controlling the operation of the pachinko gaming machine P triggered by the ball detection of the gate 90.
Here, when the game ball passes through the gate 90, the detection is stored as a normal symbol start memory number within a range of an upper limit (for example, four), and the normal symbol is displayed when the normal symbol variation display game is started. A process of subtracting 1 from the starting memory number is performed. This normal symbol start memory number is displayed on the normal symbol hold number display portion (not shown) of the digital display portion 80.

When the normal symbol variation display game is won, the movable piece 53 of the second start opening 52 is opened, the winning rate of the game ball to the start winning opening 50 is increased, and the chance of starting the variation display game is increased. It is supposed to be.
(Big prize 8)
Here, the special winning opening 8 will be described in detail.
As shown in FIGS. 3 and 4, the special winning opening 8 in the present embodiment includes a storage case 10 fitted in the opening 1 </ b> A formed in the game board 1, a rotating body 20 attached to the storage case 10, and rotation. It comprises a drive device 30.

The storage case 10 is a box having an opening 11 on the front side, and is for storing the rotary body 20 and the rotary drive device 30. Bearings 15 are provided on the left and right sides of the opening 11, and a chamfer 13 is formed on the upper edge of the opening 11. The upper surface of the bottom plate of the storage case 10 is below the opening 11. An inclined portion 14 that is inclined upward from the edge toward the back is formed. The chamfered portion 13 is for making it easier for a game ball to enter from the upper opening portion 11A of the opening portion 11, and the inclined portion 14 is for making it difficult for a game ball to enter from the lower opening portion 11B of the opening portion 11. .
Further, a discharge port 12 for discharging game balls that have entered the storage case 10 is formed in the bottom plate of the storage case 10 and on the back side of the inclined portion 14. In the vicinity of the discharge port 12, a ball detection sensor (not shown) is provided, and a winning ball is counted based on the detection of the ball detection sensor and a prize ball is paid out. Further, as shown in FIG. 5, a U-shaped reflecting sphere cover 16 in a plan view is attached to the front side of the storage case 10. The reflective sphere cover 16 is made of a transparent member, and protects the game sphere that collides with the rotating body 20 and rebounds from directly hitting the glass (transparent plate) of the glass frame 3A.

As shown in FIG. 4, the rotating body 20 is a semi-cylindrical housing 21 having a rectangular flat surface 21A and a curved surface 21B formed on the opposite side of the flat surface 21A. The unit 15 is supported so as to be rotatable in the front-rear direction via a rotation shaft 22 provided in the horizontal direction. Then, as shown in FIG. 3, by positioning the flat surface 21A so as to be vertical, as shown in FIGS. 4 and 5, the front side of the opening 11 (the front face facing the player) is closed. It has become. Although not particularly illustrated, it is preferable to cover the surface of the rotator 20 with a buffer member for absorbing the impact of a game ball collision.
Here, when the flat surface 21A is located on the front side, the flat surface 21A is flush with the board surface, and there is a gap through which the game ball can pass between the housing 21 and the reflective ball cover 16. Secured. On the other hand, as shown by a two-dot chain line in FIG. 4, when the curved surface 21B is located on the front side, the curved surface 21B protrudes forward from the board surface, and the housing 21 and the reflecting sphere cover 16 Game balls cannot pass between them. When the flat surface 21A is positioned on the lower side (see FIG. 6B), a game ball is placed between the curved surface 21B and the upper edge (the chamfered portion 13) of the storage case 10. If no gap is formed and the flat surface 21A is located on the upper side (see FIG. 7C), a game ball is placed between the flat surface 21A and the chamfered portion 13. A passable gap is formed.

Further, as shown in FIG. 5, the housing 21 is arranged such that, when viewed in plan, the left and right ends of the curved surface 21B are thinner than the central portion (that is, the curved surface 21B is on the upper side). When it is positioned, it is formed so as to incline downward toward the end side). For this reason, for example, as shown in FIG. 6B, the game ball on the upper surface of the curved surface 21B rolls down on both ends of the housing 21 and does not stay on the upper surface of the curved surface 21B. On the other hand, since the flat surface 21A is not provided with such an inclination, for example, as shown in FIG. 7C, the game ball on the upper surface of the flat surface 21A is difficult to fall and stays on the upper surface of the flat surface 21A. There is a case.
The rotation driving device 30 is for rotating the rotating body 20, and includes a motor 31 and a plurality of gears 32. The drive gear 32A fixed to the motor shaft meshes with the connection gear 32C, and the connection gear 32C meshes with the rotation gear 32B fixed to the rotation shaft 22 of the rotating body 20, whereby the rotation of the motor 31 is performed. This is transmitted to the rotating body 20. The motor 31 can rotate forward and backward.

(Operation of rotating body 20)
Next, the movement of the game ball accompanying the rotation operation of the rotating body 20 of the special winning opening 8 having the above configuration will be described with reference to FIGS. Here, FIG. 6 shows a case where the casing 21 as the rotating body 20 is rotated so that the upper side of the rotating shaft 22 moves forward (in the direction of the white arrow in the side view) when viewed from the front. Fig. 6 shows a case where the rotary shaft 22 is rotated so that the upper side moves backward (in the black arrow direction in a side view).
First, when the special winning opening 8 is not opened (when not in the special game state), as shown in FIG. 6A, the housing 21 is stopped with the flat surface 21A facing the front side. This is the initial state. In this state, the game ball flowing down the board surface passes between the housing 21 and the reflective ball cover 16 and falls. Next, when the housing 21 is rotated counterclockwise as viewed from the right side as shown in FIGS. 6B and 6C, the upper side of the curved surface 21B is the front side from the upper opening 11A of the storage case 10. Therefore, the game ball flowing down from above is prevented from falling on the curved surface 21B. Further, at this time, there is no gap for allowing the game ball to pass between the curved surface 21B and the chamfered portion 13 which is the lower edge portion of the storage case 10, and the game ball is guided into the storage case 10. There is nothing (hereinafter referred to as “no winning status”). In addition, the curved surface 21B moves from the opening 11 to the case outer side direction (that is, the front side), and both end portions are inclined downward, so that the game ball falling on the curved surface 21B The possibility that the game ball falls from the side and stays on the upper surface of the curved surface 21B is low.

When the housing 21 rotates to the position shown in FIG. 6D, the upper side of the flat surface 21A protrudes forward from the upper opening 11A, and a game ball is inserted between the upper end of the housing 21 and the chamfered portion 13. A gap sufficient to pass through is generated. From this position to the position where the flat surface 21A is in a horizontal state as indicated by a thin line in FIG. 6D, the game ball is guided from the upper opening 11A to the inside of the storage case 10 (hereinafter, winning can be made) Called state).
Further, although not shown, when the flat surface 21A is further rotated from the horizontal position, the flat surface 21A is inclined downward toward the front side (see FIG. 7B), and the opening 11 is closed. Since it goes, it will return to a prize-impossible state again. Then, the state in which no winning is possible is maintained until returning to the initial position.

On the other hand, when the housing 21 is rotated from the initial state in the opposite direction as described above, the lower side of the flat surface 21A is lifted forward from the lower opening 11B in FIGS. 7B and 7C. Since it protrudes, the game ball flowing down from above is prevented from falling on the flat surface 21A. The game ball staying on the upper surface of the flat surface 21A may stay on the upper surface of the flat surface 21A without falling from the side of the housing 21. If a buffer member such as rubber is attached to the flat surface 21A, the possibility is further increased.
While the housing 21 rotates from the position shown in FIGS. 7C to 7D, the flat surface 21A is inclined downward toward the rear, and the game ball riding on the upper surface of the flat surface 21A It is guided from 11A to the inside of the storage case 10. In addition to this, there is a sufficient gap between the upper end of the housing 21 and the chamfered portion 13 to allow the game ball to pass through, so the game ball that has flowed down from above and received by the flat surface 21A. Is also guided into the storage case 10. Thereafter, the winning-availability state is maintained until there is no gap between the upper end of the housing 21 and the chamfered portion 13 so that the game ball can pass therethrough. After that, the flat surface 21A is in a vertical state and is in a no-winning state until returning to the initial position. (See FIGS. 6C and 6B).

  Here, the case where the casing 21 is rotated forward (rotation in the direction of the white arrow) and the case where it is reversely rotated (rotation in the direction of the black arrow) will be compared. In both cases, the opening time of the opening 11 is the same, but when it is reversed, the flat surface 21A can be lifted so as to scoop up the game ball from below to upward at the time of initial movement. In the case of normal rotation, in addition to eliminating the game ball by the curved surface 21B from the initial movement, the flat surface 21A becomes horizontal after a gap through which the game ball can pass is formed in the upper opening portion 11A. Until then, the game ball can be guided to the inside (the game ball received by the flat surface 21A is dropped downward). Therefore, it is possible to win more game balls at the time of reverse rotation than at the time of normal rotation. In this way, by changing the rotation direction of the housing 21, even if the rotation speed and the number of rotations are the same, the ease of winning is different.

In addition, you may improve a winning rate by pausing the housing 21 for several seconds in the state of FIG. 6 (D) and FIG. 7 (D). Even in this case, the winning rate is still higher at the time of reverse rotation.
(Modification of the housing 21)
In the embodiment described above, as shown in FIG. 6C, when the curved surface 21B of the housing 21 is located on the front side, the game ball flowing down from above by the housing 21 cannot pass. Although formed, as shown in FIG. 8, it is possible to form the game ball so that it can pass between the housing 21 and the reflective ball cover 16 even if the curved surface 21B is located on the front side.

Even when formed in this way, when the curved surface 21B is positioned on the upper side, there is no gap through which the game ball can pass in the upper opening 11A, and when the flat surface 21A is positioned on the upper side, the opening is opened. A sufficient gap through which the game ball can pass can be generated in the upper portion 11A. And, the possibility of winning a prize at the time of reverse rotation is greater than that at the time of normal rotation, as described in the examples of FIGS.
Furthermore, in the above-described embodiment, the rotating shaft 22 is provided eccentrically on the flat surface 21A side of the housing 21, and the thickness from the rotation center of the rotating body 20 to the flat surface 21A and the thickness to the curved surface 21B are set. By making it different, the game ball was formed so that it would be difficult for the game ball to enter the storage case 10 during forward rotation. However, as shown in FIG. 9, the rotary shaft 22 is positioned in the height direction of the flat surface 21A at the initial position. It may be provided eccentrically above the center. In this case, the gap between the upper end of the housing 21 and the chamfered portion 13 of the storage case 10 at the initial position may be a distance through which the game ball can pass, but the game ball that falls vertically on the board surface Is unlikely to enter this gap. Even in this case, the reverse direction in which the flat surface 21A is lifted forward rather than being rotated in the forward rotation direction in which the flat surface 21A is lifted rearward with the position indicated by the solid line in FIG. 9 as the initial position. The number of game balls that can be guided to the inside of the storage case 10 is increased by rotating it to the right.

(Other examples of rotating body 20)
By the way, the shape of the rotating body 20 is not limited to the casing 21. For example, the rotating body 20 may be a plate-like rotating plate 23.
Specifically, as shown in FIG. 10, the rotating body 20 is a rectangular rotating plate 23, and the rotating shaft 22 is shifted from the center of the rotating plate 23 in the width (height when vertical) state. A wide portion 23A having a relatively long length from the rotating shaft 22 to one long side end portion, and a narrow portion having a length from the rotating shaft 22 to the other long side end portion shorter than the wide portion 23A. 23B is formed. In the initial state, as shown by a solid line in FIG. 10A, the rotating plate 23 is positioned in a vertical state with the narrow portion 23B on the upper side.

  When the rotating plate 23 is rotated from the initial position in the direction of the white arrow shown in FIG. 10 (forward rotation direction), the narrow portion 23B protrudes forward as shown by a thin line in FIG. Although the narrow ball portion 23B receives the game ball flowing down from above and can guide the game ball to the upper opening 11A, the gap between the end of the narrow portion 23B and the reflective ball cover 16 is large. In some cases, the game ball falls without hitting the narrow portion 23B. The game ball barely received by the narrow portion 23B is also likely not to be guided into the storage case 10 because the narrow portion 23B moves from the upper side to the lower side. Further, when the rotating plate 23 is inclined downward from the horizontal state to the front side, the game ball falls down without being guided into the storage case 10. Further, as shown in FIG. 10B, even when the wide portion 23A is rotated until it is positioned on the front side, the game ball can be guided into the storage case 10 because the chamfering of the wide portion 23A and the storage case 10 is performed. This is a period from when a gap through which a game ball can pass is formed between the rotating plate 23 and the rotating plate 23 to a horizontal state.

On the other hand, when the rotating plate 23 is rotated from the initial position in the direction of the black arrow (reverse direction) shown in FIG. 10, the wide portion 23A is located below the lower opening 11B as shown in FIG. Therefore, the game ball can be lifted up by scooping up, so that the game ball is guided into the storage case 10. Further, as shown in FIG. 10 (D), even when the narrow portion 23B is rotated until it is positioned on the front side, the narrow portion 23B moves toward the inside of the storage case 10, and therefore, the narrow portion 23B. There is also a possibility that a game ball riding on the upper surface of the inside enters the storage case 10.
Thus, even if the rotating body 20 is plate-shaped, the winning rate can be changed between forward rotation and reverse rotation.

  As another shape of the rotating body 20, as shown in FIG. 11, a structure in which a bowl-shaped body 24 having a semicircular cross section is attached to the rotating shaft 22 symmetrically can be used. When formed in this way, when the rotating body 20 is rotated in the forward rotation direction from the initial position shown in FIG. 11A, a game ball is opened from the upper opening 11A as shown in FIG. 11B. However, the game ball received by the recess 24A of the bowl-shaped body 24 falls downward. On the other hand, when rotated in the forward direction from the initial position, as shown in FIG. 11C, the game ball is not only guided into the storage case 10 from the opening upper portion 11A but also received by the recess 24A. Since the game balls are picked up and guided into the storage case 10, the winning rate is higher than that in forward rotation.

Thus, depending on the shape of the rotating body 20, even if the rotating shaft 22 is positioned at the center in the width direction and the thickness direction, the winning rate can be changed depending on the rotation direction. Even when the rotating body 20 is a plate member as shown in FIG. 10 and the rotation shaft 22 is provided at the center in the width direction of the plate member, the rotation speed is constant and the reverse rotation is constant. The winning rate will be different. However, by devising the shape of the rotating body 20 as described above, it is possible to change the flow-down mode of the game ball, and to make a large difference in the winning rate between forward rotation and reverse rotation.
(Example of operation control of rotating body 20)
Next, an example of proper use of normal rotation and reverse rotation of the rotating body 20 will be described.

First, it is assumed that the rotational speed of the rotating body 20 is constant both in the case of normal rotation and in the case of reverse rotation.
On the other hand, the special gaming state includes 15 round jackpots 1 that are started when special symbol 1 is won, 15 rounds jackpot 2 that is started when special symbol 2 is won, and 2 rounds. In addition, after the jackpot game is over, a predetermined number of advantageous games (for example, time reduction or probability change) are performed. Then, the rotary body 20 is set to rotate forward (difficult to win) when the round 15 big hit is 1, and to rotate reversely (easy to win) when the round 15 big hit is 2. In addition, after the end of 1 round of 15 rounds, the number of advantageous games is added to increase the next jackpot pullback rate, thereby compensating for the balls in the jackpot game. On the other hand, after the end of 2 rounds of 15 rounds, an advantageous game is not added and the next jackpot pullback rate is lowered to achieve a balance with 1 of 15 rounds.

In the case of two rounds, the rotation direction of the rotating body 20 in the first round and the second round is reversed. Whether to rotate forward or reverse in the first round may be determined by lottery, for example. By forming the rotary body 20 in this way, it is not possible to distinguish whether it is a big hit of 15 rounds or a round of 2 rounds when the rotating body 20 is first moved, so that the player's expectation can be enhanced.
In addition, even if 1 for 15 rounds is won, the rotating body 20 is controlled to rotate in reverse with a predetermined probability, and even if 2 for 15 rounds is won, the rotating body 20 is controlled to rotate normally with a predetermined probability. Good. Further, the probability of normal rotation may be increased when hitting with probability change, and the probability of reverse rotation may be increased when hitting without probability change. Furthermore, the initial rotation direction may be different between two rounds with probability variation and two rounds without probability variation.

As described above, the special winning opening 8 according to the present embodiment is formed so as to be opened and closed by the rotation of the rotating body 20, so that noise such as pakapaka that occurs when the conventional door is opened and closed is suppressed. Can do.
In addition, the change in the flow path of the game ball is diversified by colliding with the rotating body 20 being rotated, and the chance of taking in and removing the game ball is added to the process of taking the game ball, thereby enhancing the interest of the game. This effect is further increased when the rotation direction of the rotating body 20 is changed.
In the above-described embodiment, the case where the rotator 20 is provided in the big prize opening 8 has been described. However, this mechanism may be used for a prize opening other than the big prize opening. In addition, the present invention includes those in which the rotating body 20 is rotated only in one direction of normal rotation and reverse rotation. Even in such a case, it is possible to take in a plurality of game balls without generating noise when the special winning opening is released.

  In the above-described embodiment, the pachinko gaming machine has been described as an example of a type called a digital machine, but the present invention can be used for a pachinko gaming machine of a type other than a digital machine. Needless to say.
