Description

  The present invention relates to a gaming machine such as a pachinko machine that is installed and used in a game hall such as a pachinko parlor.

  One of the gaming machines installed in the amusement hall is a pachinko machine. In this pachinko machine, a game board in which a game area for launching a pachinko ball (game ball) is formed is disposed in a main unit serving as a mounting portion, and the front surface of the game board is covered with a glass frame holding a glass plate. It is the composition which becomes. A game area restricted by rails is formed on the game board surface, and this game area is configured to include a start winning opening (start chucker), a normal winning opening, a passing winning opening, an attacker, a symbol display device, and the like. ing. The winning of a pachinko ball in this winning opening. The pachinko ball is given a certain value, and the pachinko ball (prize ball) acquired by playing the game can be exchanged for various prizes. The player aims to acquire a large number of pachinko balls, and looks forward to playing a game in a jackpot mode in which a large number of pachinko balls can be acquired in a short period of time.

  In such a pachinko machine, the decorative frame is attached so as to surround the symbol display device provided in the central portion of the game area. An opening for allowing the pachinko ball to flow is formed in the decorative frame, and the pachinko ball that has flowed into the decorative frame from the opening is dropped downward through a stage formed in the lower part of the decorative frame. A start winning opening is formed below the decorative frame. When the pachinko ball enters the start winning opening and wins, the symbol display device operates. When the winning prize opening is won, the symbol display device performs variable display of symbols in a plurality of display areas for sequentially displaying a plurality of types of symbols. Whether or not to shift to the jackpot mode is determined by a jackpot determination lottery performed in response to winning at the start winning opening. When “hit” is won in this jackpot determination lottery, a combination of symbols constituted by specific symbols is displayed in each display area, and at least the right to shift to the jackpot mode is obtained. A big prize opening is provided in the back of the attacker provided in the game area. When the jackpot mode is entered, the attacker operates repeatedly up to a certain number of times on condition that the continuation condition is satisfied, with one round from the opening to closing of the winning prize opening. In one round, the attacker closes the big prize opening when, for example, 30 seconds elapses or ten pachinko balls are won after opening the big prize opening. When shifting to such a jackpot mode, the player can win a larger number of pachinko balls than usual in the grand prize opening, and can acquire a large number of prize balls.

  The stage formed in the decorative frame temporarily receives a pachinko ball and stays there. This stage is usually formed with a passage inclined forward, and pachinko balls that have fallen from the stage through this passage enter a starting start port provided below and are easy to win. In such a pachinko machine, since the movement of the pachinko ball while staying on the stage attracts the player's interest, the player's sense of tension in the game can be enhanced.

  However, in the pachinko machine configured in this way, pachinko balls that flow into the decorative frame are guided onto the stage and temporarily stay on the stage, but all the pachinko balls move monotonously on the stage, It is difficult to attract the player's interest. For this reason, it is conceivable that a rotating body that is rotationally driven is provided at the center of the stage, and the pachinko balls on the stage are moved irregularly to attract the player's interest. However, if a rotating shaft is provided at the center of such a rotating body, a space cannot be secured below the rotating body. For this reason, when a falling hole for dropping a pachinko ball is formed in the rotating body, it is difficult to provide a plurality of passages for guiding the pachinko ball dropped from the dropping hole below the rotating body. There was a problem that it was not possible to improve the gameability.

  The present invention has been made in order to solve the above-described problems, and provides a gaming machine in which game paths are improved by diversifying a course of a game ball dropped from a dropping hole of a rotating body.

In order to achieve the above object, a gaming machine according to the present invention is a gaming machine provided with a stage for staying a game ball launched into a gaming area above a winning opening arranged at a predetermined position in the gaming area. The stage includes a rotating body formed with at least one drop hole for dropping the game ball and driven to rotate, and a rotating support body that engages with an outer peripheral portion of the rotating body and rotatably supports the rotating body. And a gap is formed in the engaging portion between the rotating support and the outer peripheral portion of the rotating body .

  The outer periphery of the rotating body includes a substantially annular flange formed on the outer peripheral surface of the rotating body along the rotation direction, and the rotating support engages with the flange and rotates. The body is rotatably supported.

Further , the lower surface of the flange portion is in contact with the rotation support body, and the gap is formed between the upper surface and outer peripheral surface of the flange portion and the rotation support body.

Further, the rotating support body is composed of two disks and a cylindrical boss that connects the two disks at the center, and the flange portion is interposed between the two disks. The upper surface of the collar part is spaced apart from the upper disk, and the outer peripheral surface of the collar part is spaced from the boss.

The rotating body is provided with a plurality of dropping holes for dropping game balls at substantially equal positions from the center of rotation at equal intervals in the rotation direction. On the rotating body, adjacent dropping holes are provided. A plate-like protrusion is provided so as to extend from the outer periphery of the rotating body toward the center of rotation, and each tip of the protrusion in the direction of the center of rotation is a game ball. It is characterized by being separated from each other wider than the size of.

Further, a tubular winning high probability passage that has an opening at a position where the dropping hole passes vertically above the rotating body, and allows a game ball that has entered the opening to flow out into the winning opening. And a winning low probability passage that is arranged on both the left and right sides of the winning high probability passage and causes the game ball that has fallen from the dropping hole to flow out so as to fall out of the winning opening, and an outer surface of the winning high probability passage The bottom surface of the winning low probability passage is continuous, and the outer surface of the winning high probability passage projects upward from the bottom surface of the winning low probability passage.

  The gaming machine of the present invention is a gaming machine in which a stage for staying a game ball launched in the game area is provided above a winning opening arranged at a predetermined position in the game area, the stage being the game ball A rotating body that is rotated and driven to form at least one drop hole for dropping the rotating body, and a rotating support body that rotatably supports the rotating body by engaging with the outer peripheral portion of the rotating body. Since it is not necessary to provide a rotating shaft at the center of the body, a space can be secured below the rotating body. For this reason, a plurality of passages for guiding the game ball dropped from the drop hole can be provided below the rotating body. For this reason, it is possible to provide a plurality of passages for guiding the game ball dropped from the drop hole below the rotating body, and it is possible to diversify the course of the game ball and improve the game performance.

  The outer peripheral portion of the rotating body includes a substantially annular flange formed on the outer peripheral surface of the rotating body along the rotation direction, and the rotating support engages with the flange to cause the rotating body to move. Since it supports rotatably, a rotation support body becomes easy to engage with a collar part, and it becomes easy to support a rotation body rotatably.

  A plurality of the rotation supports are arranged at positions that divide the outer periphery of the collar part at equal intervals, and engage with the collar part to rotatably support the rotary body. Compared with the case where the shaft is provided to support the rotating body, the stress is distributed to three or more pulleys, so that the durability of the component can be improved.

  Since a gap is formed in the engaging portion between the rotating support and the flange portion, the engaging portion has a backlash, and the rotation is unstable due to the occurrence of blurring at the rotation center of the rotating body. , The movement of the game ball becomes irregular and moves unexpectedly. For this reason, a player's interest can be attracted.

  Since the rotation body includes a plurality of teeth formed on the outer peripheral surface of the rotation body along the rotation direction, and a rotation driving mechanism that transmits the rotation to the plurality of teeth to rotate the rotation body. The rotation drive mechanism to rotate can be arrange | positioned on the outer side of a rotary body, and space can be ensured under the rotary body.

  Below the rotating body, a winning high probability passage that guides the game ball dropped from the drop hole into the winning opening, and the game ball dropped from the dropping hole is dropped to the game area outside the winning opening. Since the winning low-probability passage is formed in such a manner, the path of the game ball can be diversified below the rotating body, so that the gameability can be improved.

  A pachinko machine 10 that is this embodiment of the gaming machine shown in FIG. 1 includes a main unit 11, a game board unit 12, and a glass frame (opening frame) 13. The main unit 11 is provided with devices that are operated according to the gaming state, such as a pachinko ball launcher, a prize ball payout device, a power supply circuit, a lamp, and a speaker.

  The game board unit 12 includes a game board 12a and a control circuit device 12b. In the game area on the front side of the game board 12a, a symbol display device 14, a start winning port (winning port) 15, a normal winning port 16, a passing winning port 17, an attacker 18, an out port 19, a decorative frame 20, and the like are provided. It has been. A control circuit device 12b is provided on the back side of the game board 12a, and this control circuit device 12b controls the operation of various devices according to the gaming state. In addition, although illustration is abbreviate | omitted, in the game area | region of the game board 12a, several obstacle nails, a windmill, etc. are provided in the suitable place. Further, a transparent glass plate 13a is attached to the glass frame 13 so as to cover the game area.

  The control circuit device 12b is a main control board (main control device) 12c for executing a game according to the model of the pachinko machine 10, the display control of the symbol display device 14, the lighting control of the lamp, the sound control output from the speaker, etc. Sub-control board (sub-control device) 12d for performing

  When the operation handle H is operated, the pachinko balls 50 which are game balls are launched one by one into the game area of the game board 12a by the pachinko ball launching device, and the start winning port 15, the normal winning port 16, the passing winning port 17, and the out port 19 Enter one of the following. When the pachinko ball 50 enters the winning prize opening 15 (wins), the symbol display device 14 is actuated, and the variable display of the displayed symbol is performed for a predetermined time to perform a hit determination and effect processing. And when the variable display of symbols is stopped, if a predetermined symbol combination is obtained on the winning winning position, it will be a big hit, and in a gaming state that will be more advantageous for the player than usual in obtaining gaming profits It is shifted to a certain jackpot mode for a predetermined period.

  When shifting to the jackpot mode, for example, the attacker 18 made of an openable / closable door member is opened / closed for a predetermined time or until a predetermined number of pachinko balls 50 are won. Changes from the closed state to the open state. This operation is repeated a predetermined number of times. When a pachinko ball 50 enters the winning prize opening 15, the normal winning opening 16, or the large winning opening behind the attacker 18, a predetermined number of pachinko balls (prize balls) 50 are paid out. In other words, the number of prize balls corresponding to the type of the winning hole containing the pachinko ball 50 is paid out from the payout port 21 to the ball tray 22. On the other hand, when the pachinko ball 50 does not win any of the start winning port 15, the normal winning port 16, and the attacker 18, these pachinko balls 50 are inserted into the out port 19 formed at the lower end of the game board 12a. It is guided and collected in the body unit 11 as a lost ball.

  As shown in FIG. 2, the decorative frame 20 has an opening 20a formed at the center thereof, and the above-described symbol display device 14 is exposed to the front through the opening 20a. A movable stage unit 23 is provided below the opening 20a.

  A guide passage 30 for guiding the pachinko ball 50 into the decorative frame 20 is provided on the left side wall portion of the decorative frame 20. The left end opening 30a is formed in the outer wall surface, and the right end opening 30b is formed in the inner wall surface. These openings 30 a and 30 b are formed at a position where the opening 30 b is lower than the opening 30 a, and the inner diameter of the guide passage 30 is slightly larger than the outer diameter of the pachinko ball 50. For this reason, the pachinko ball 50 that has flowed into the guide passage 30 through the opening 30a from the game area moves downstream in the guide passage 30 by its own weight and is guided into the decorative frame 20 through the opening 30b. Is done.

  The movable stage unit 23 includes a first stage 31 and a second stage 32 formed below the first stage 31, and is configured in two upper and lower stages. In the center of the upper surface 31a of the first stage 31, there is formed a mortar-shaped recess 31b having an elliptical outer periphery and gradually decreasing in inner diameter as it goes downward. Further, the center of the recess 31b will be described later. An opening 34 is formed in the upper part of the rotating cruun (rotating body) 41 to expose a substantially disc-shaped receiving tray 33, and the receiving tray 33 constitutes a part of the recess 31b.

  The receiving tray 33 is formed with three drop holes 35 centered on the center of the tray 33 so as to be spaced at equal angles, and between the two drop holes 35 adjacent to each other in the rotation direction, A plate-like blade 36 protruding in the shape is formed. The blades 36 guide the pachinko balls 50 flowing between the blades 36 to the drop holes 35 or play the pachinko balls 50 that have collided. Each drop hole 35 is formed to be slightly larger than the outer diameter of the pachinko ball 50. A hemispherical projection 37 is formed between the drop hole 35 and the outer periphery of the tray 33 and at the center of the tray 33 so as to be adjacent to the drop hole 35. Since the pachinko balls 50 are scattered by the projections 37 and the traveling direction changes, the movement of the pachinko balls 50 on the tray 33 becomes more irregular and complicated. In the present embodiment, the outer periphery of the recess 31b is described as being elliptical, but the outer periphery of the recess 31b is not limited to an ellipse, and may be an appropriate shape such as a circle.

  Further, a slide-like inclined passage 38 is formed on the upper surface 31a of the first stage 31 so that the upstream end is connected to the opening 30b, and the downstream side of the inclined passage 38 faces the outer periphery of the recess 31b. It extends. The inclined passage 38 allows the pachinko sphere 50 that has flowed out of the opening 30b to flow into the recess 31b. The recess 31b causes the pachinko sphere 50 that has flowed in, for example, to make a revolving motion due to inertia along the edge thereof to temporarily stay. Further, the tray 33 causes the pachinko ball 50 to drop through one of the three drop holes 35.

  In addition, the first stage 31 incorporates a rotary cleon 41 and a rotation drive mechanism 40 that rotationally drives the rotary cleon 41. As will be described later, the rotation driving mechanism 40 transmits the rotation to a rotating crude 41 that is rotatably supported to rotate the rotating crude 41.

  As shown in FIG. 3, the rotary cleon 41 includes a main body 51 formed in a substantially cylindrical shape, a receiving tray 33 formed on the upper surface of the main body 51, and a flange formed on the outer peripheral surface of the main body 51 along the rotation direction. It is comprised by the gear part (plural teeth) 53 in which 40 teeth were formed in the lower end part of the outer peripheral surface of the main body 51 along the rotation direction. Four pulleys (rotating supports) 42 are arranged on the outer periphery of the flange portion 52 at positions where the outer periphery is divided into four. As shown in FIG. 4, the pulley 42 includes two disks 42a and 42b, and a cylindrical boss 42c that connects the disks 42a and 42b at the center. The rotation shaft 54 fixed to the movable stage unit 23 of the boss 42c is inserted into the boss 42c, so that the pulley 42 is rotatably held. The outer periphery of the flange portion 52 is engaged with the pulley 42 by being inserted between the two disks 42a and 42b. As described above, the four pulleys 42 are arranged on the outer periphery of the flange portion 52, and the four pulleys 42 that are rotatably held and the flange portion 52 are engaged with each other, whereby the rotary cleon 41 is It is supported rotatably.

  Thus, since the flange 52 is engaged with the four pulleys 42 and the rotary cleon 41 is rotatably supported on the outer peripheral side thereof, it is necessary to provide a rotation shaft at the rotation center of the rotary cleon 41. Absent. For this reason, it is possible to arrange a plurality of passages for guiding the pachinko balls 50 to the outside of the decorative frame 20 below the rotating croon 41 while securing a space inside the main body 51 and below the rotating croon 41. The position is not limited. Thereby, since the course of the pachinko ball 50 falling from the drop hole 35 formed in the receiving tray 33 can be diversified, the playability can be improved.

  Further, as shown in FIG. 4, the thickness d1 of the flange portion 52 is thinner (d1 <h) than the height h of the boss 42c of the pulley 42, and has a gap d2. Further, the pulley 42 is disposed so that a gap d3 is also formed between the outer peripheral surface of the flange portion 52 and the outer peripheral surface of the boss 42c. Due to the gap d2 and the gap d3, the engagement portion between the flange portion 52 and the pulley 42 is rattled. Due to this rattling, the rotational center of the rotating cruel 41 is displaced, causing vertical blurring in the rotating crude 41 or moving in the plane of rotation. Compared to the case where the rotational center is constant. Then, the movement of the pachinko ball 50 becomes irregular and moves unexpectedly, which can attract the player's interest.

  In addition, since the rotary clune 41 is supported at four locations by the four pulleys 42, the stress is dispersed compared to the case where the rotary shaft is provided at the center of rotation of the rotary crune 41 and rotated, so that the durability of the parts is improved. improves.

  Next, the rotation drive mechanism 41 will be described. As shown in FIG. 3, the rotation drive mechanism 40 includes an origin detection sensor 43, a sensor gear 44, an intermediate gear 45, a motor gear 46, and a motor (rotation drive means) 47 that is a stepping motor. Yes. As described above, the gear portion 53 is formed on the outer periphery of the lower end portion of the rotating cleon 41. Further, since the rotating cleon 41 is rotatably supported, the rotating crude 41 functions as a gear. As shown in FIG. 5, the gear portion 53 meshes with a sensor gear 44 that is rotatably supported by bearings 60 a and 60 b formed on the movable stage unit 23. Similarly, the sensor gear 44 meshes with an intermediate gear 45 rotatably supported by bearings 61a and 61b. Further, a motor gear 46 is rotatably attached to the motor 47 fixed to the movable stage unit 23, and the motor gear 46 is rotated by the motor 47. The motor gear 46 meshes with the intermediate gear 45.

  When the motor gear 46 is rotated by the motor 47, this rotation is transmitted to the gear portion 53 via the intermediate gear 45 and the sensor gear 44, and the rotating cruel 41 rotates. The number of teeth of the motor gear 46 is 20, the number of teeth of the intermediate gear 45 is 30, and the number of teeth of the sensor gear 44 is 40. Moreover, the gear part 53 is 40 teeth. Since the gear pitches of the gears 44, 45, 46, and the rotating crune 41 are the same, the gear ratio between the motor gear 46 and the sensor gear 44 is 1: 2, and the rotation gear 41 and the sensor gear 44 have a gear ratio. The gear ratio is 1: 1. For this reason, when the motor gear 46 rotates twice, the rotating cruel 41 rotates once. At this time, the sensor gear 44 also makes one rotation in the same manner, so that the rotational speeds of the sensor gear 44 and the rotating cruel 41 are the same.

  Further, as shown in FIG. 3, a shield projection 44a that engages with a PI (photo interrupter) 43 provided on the movable stage unit 23 is formed on the lower surface of the sensor gear 44 so as to protrude downward. . The PI 43 includes a light projecting unit 43a and a light receiving unit 43b, and is electrically connected to the main control board 12c. The PI 43 outputs a detection signal to the main control board 12c when light is blocked between the light projecting unit 43a and the light receiving unit 43b by the shielding projection 44a. For example, when the shielding protrusion 44a is at a position rotated 90 ° clockwise from the PI 43 (position shown in FIG. 6A), when the motor gear 46 is rotated 180 ° counterclockwise by the motor 47, the intermediate gear 45 The rotation is transmitted to the sensor gear 44 through the rotation of the sensor gear 44, and the sensor gear 44 rotates 90 ° counterclockwise. At this time, as shown in FIG. 6B, the shielding protrusion 44a moves to a position where the light between the light projecting unit 43a and the light receiving unit 43b is shielded, and the PI 43 outputs a detection signal to the main control board 12c. To do. The main control board 12c detects the position shown in FIG. 6B, and controls the rotation of the motor 47 with this position as the origin. In FIG. 6, in order to avoid complication of the drawing, the flange portion 52 and the pulley 42 are omitted, and only the state where the gear rotates is illustrated.

  As shown in FIGS. 5 and 7, the second stage 32 is formed to be positioned below the first stage 31, and a winning high probability passage 63 that guides the pachinko ball 50 to the start winning opening 15, It has winning low probability passages 64a and 64b for distributing the pachinko ball 50 to the left and right of the start winning opening 15. The second stage 32 is composed of a room that forms a substantially rectangular parallelepiped space. In the second stage 32, a substantially tubular prize-high probability passage 63 extending from the center rear side to the front side is formed. As described above, since the rotation axis for rotating the rotary clown 41 is not provided at the center, the winning-high probability passage 63 can be formed at the center of the second stage 32. In addition, an opening 63a for allowing the pachinko ball 50 to flow into the winning high probability passage 63 is formed in the upper rear portion of the winning high probability passage 63, and the pachinko ball 50 flows out toward the start winning opening 15 in the front. An opening 63b is formed. The cross sections of the openings 63 a and 63 b and the winning probability probability passage 63 are formed to be slightly larger than the outer diameter of the pachinko ball 50.

  The winning-high probability passage 63 is inclined so that the front is lower than the rear, and the pachinko ball 50 dropped from the drop hole 35 located above the opening 63a passes through the opening 63a. It flows into 63, moves to the downstream side by its own weight, and flows out of the decorative frame 20 through the opening 63b. The decorative frame 20 is attached to the game board 12a so that the opening 63b is vertically above the start winning opening 15, and the pachinko ball 50 that has flowed out and dropped from the opening 63b has a high probability. to go into.

  The winning low probability passages 64a and 64b are configured by the outer wall 65 of the winning high probability passage 63, the left and right bottom surfaces connected to the sides thereof, and the side walls. The winning low probability passages 64 a and 64 b are inclined so that the front is lower than the rear, and the pachinko ball 50 that has dropped from the drop hole 35 located above is caused to flow down and fall to the outside of the decorative frame 20. Since the decorative frame 20 is attached to the game board 12a as described above, the pachinko ball 50 dropped from the winning low probability passages 64a and 64b located on the side of the winning high probability passage 63 is detached from the start winning opening 15. The probability of winning is low. When the pachinko ball 50 falls from the drop hole 35 located above the outer wall 65 of the winning high probability passage 64, the pachinko ball 50 is bounced by the outer wall 65 and passes through either the winning low probability passage 64a or 64b. After passing, it flows down to the front.

  In this way, the movable stage unit 23 makes the pachinko ball 50 temporarily stay on the first stage 31 to attract the player's interest, and also the probability that the pachinko ball 50 enters the start winning opening 15 ( High probability or low probability). Thereby, it is possible to give the player a sense of tension as to whether or not the pachinko ball 50 dropped from the second stage 32 enters the start winning opening 15.

  Next, a series of actions in the pachinko machine 10 of the present embodiment configured as described above will be described. When the player operates the launch handle H to activate the pachinko ball launching device and launches the pachinko ball 50 into the game area of the game board 12a, the launched pachinko ball 50 passes through the start winning opening 15, the normal winning opening 16, and the passing. A prize is entered in any one of the winning openings 17 or an out opening 19 is entered.

  As shown in FIG. 7, when the pachinko ball 50 launched into the game area of the game board 12a flows into the guide passage 30 through the opening 30a, it enters the decorative frame 20 through the opening 30b. The pachinko balls 50 that have entered the decorative frame 20 flow down on the first stage 31 through the inclined passage 38 and flow into the recess 31b. The pachinko ball 50 that has flowed into the recess 31b stays temporarily by performing a revolving motion or the like on the recess 31b. In rare cases, a pachinko ball 50 that has bounced off from an obstacle nail, a windmill, or the like in the game area may run directly on the first stage 31 from the game area.

  The pachinko ball 50 temporarily stays on the recess 31b, and then moves by its own weight onto the tray 33 of the rotating croon 41. The tray 33 is rotating, the pachinko balls 50 are repelled by the blades 36 and the projections 37, and the pachinko balls 50 repeat irregular and complicated movements. Since the receiving tray 33 is shaken at the center of rotation as described above, the pachinko ball 50 is made to move more irregularly and complicatedly by vibration in the vertical direction of the receiving tray 33 and movement in the rotation plane. For this reason, since the pachinko ball 50 moves irregularly and unexpectedly, it is possible to attract the player's interest.

  The pachinko ball 50 may be bounced by the blades 36 and return to the outside of the tray 33 again. However, the pachinko ball 50 enters one of the three drop holes 35 of the tray 33 after repeating such movement. .

  For example, when the rotating croon 41 rotates the tray 33 to the position shown in FIG. 6 (B) and the drop hole 35 is positioned vertically above the winning high probability passage entrance 63, as shown in FIG. When 50 falls from the drop hole 35, the pachinko ball 50 flows into the winning prize probability passage 63 through the opening 63a of the second stage 32. Thereafter, it passes through the winning high probability passage 63 and flows out from the opening 63b. The outflow pachinko ball 50 falls toward the start winning opening 15 and enters the start winning opening 15 with high probability. On the other hand, as shown in FIG. 8, when the pachinko ball 50 falls from the drop hole 35 at another position, the pachinko ball 50 flows out through the winning low probability passage 64a or 64b of the second stage 32, and the start winning prize is obtained. Since it falls to the left and right of the mouth 15, the winning probability is low.

  In the above embodiment, the flange portion is formed along the rotation direction on the outer peripheral surface of the rotating croon, and the four pulleys are arranged at positions that divide the outer periphery of the flange portion at equal intervals. Alternatively, two or more pulleys may be arranged at positions where the outer periphery of the flange portion is divided at equal intervals.

  Further, although the description has been given using the pulley as the rotation support, the present invention is not limited to this, and any rotation support can be used as long as the rotation crew can be rotatably supported from the outer peripheral side. For example, a plurality of rotatable rollers are provided at positions that divide the outer periphery of the rotating crew at equal intervals, and the plurality of rollers are brought into contact with the outer peripheral surface of the rotating crew and attached toward the center of the rotating crew. The rotating croon may be supported in a freely rotating manner. In this case, the flange portion may not be provided.

  Alternatively, a plurality of rollers may be brought into contact with the lower surface of the flange portion so that gaps are formed between the outer peripheral surface below the flange portion and the plurality of rollers. In this case, it is possible to cause blurring in the rotation of the rotating croon.

  Moreover, in the said embodiment, three drop holes 35 are provided so that each may become an equiangular space | interval centering on the center of the saucer of a rotation croon, and it is a blade | wing between two fall holes adjacent to the rotation direction of a saucer. However, the present invention is not limited to this, and the number and positions thereof may be set as appropriate.

  Further, in the above embodiment, the winning high probability passage 63 is provided in the center of the second stage 44, and the two winning low probability passages 64a and 64b are provided on the left and right sides thereof. You can do it.
