Description

  The present invention relates to a gaming machine such as a pachinko gaming machine in which the movement of a game ball in a game area is complicated to enhance the interest of the game.

  Some conventional gaming machines, for example, pachinko gaming machines, include a rotating unit in which a magnetic body (magnet) is included in a gaming area where a game ball flows down. This rotating unit can transfer the game ball by adsorbing the game ball on the surface of the cylindrical rotating member with a magnetic material and rotating in this attracted state.

In order to enclose the magnetic body in the conventional rotation unit, the rotation member is divided vertically along the rotation axis, and the storage body is provided in each cross section to store the magnetic body, or the rotation body is rotated. The surface of the member is recessed to form a recess, and a magnetic material is accommodated in the recess, and a protective sheet that also serves as a decoration is applied from above the recess (for example, see Patent Document 1).
JP-A-7-289699

  However, in the configuration in which the magnetic body is housed in the vertically-rotating member, the arrangement location of the magnetic body is limited. Specifically, in order to dispose the magnetic body in the vicinity of the outer peripheral surface of the rotating member, the wall portion defining the outer peripheral surface side of the storage recess, that is, the partition portion on the side where the game ball is attracted (contacted) is thinned. There is a need to. However, this wall portion is weak against impact because the portion on the dividing surface side of the rotating member is a free end. If such a wall portion is made thin, cracks are likely to be generated from the divided end of the rotating member due to the impact of the game ball, which is not preferable. For this reason, in this type of rotating member, the magnetic body has to be arranged closer to the central axis. Further, since the number of parts is increased because of the form of division, there remains room for reducing manufacturing efficiency and manufacturing cost.

  In the rotating member that holds the magnetic body in the recess with the protective sheet, the protective ball is easily damaged because the game ball repeatedly contacts, and in the worst case, the protective sheet is broken during the game and the magnetic body is exposed. However, there is a risk of dropping the game area together with the magnetic material while the game ball is attracted. Furthermore, when the protective sheet is stuck with an adhesive, it takes time to dry the adhesive, and it is difficult to improve the manufacturing efficiency.

  Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rotating unit capable of arranging a magnetic body at a desired position without complicating the configuration of the rotating member. It is intended to provide a gaming machine equipped.

The present invention has been proposed in order to achieve the above-mentioned object.

Since it is configured so as to be closed by the end of the reference rotation base, the opening edge that is a fragile portion of the storage recess can be shifted from a position where the game ball easily contacts, and damage to the rotation member can be prevented. The magnetic body can be disposed at a desired position of the rotating member without concern. Further, the magnetic material can be accommodated without requiring extra part division or attaching a seal to the surface.

The center case 5 includes an attachment board 20 to be attached to the surface of the game board 1, and a hook-shaped armor portion 21 is provided on the upper portion of the attachment board 20 so as to protrude forward over the entire width. A vertically long side part 22 is extended downward from the end part, and a bottom part 23 is provided in a state where the lower ends of the left and right side part parts 22 are connected to each other, and the armor part 21, the left and right side parts 22 and the bottom part 23 are provided. An opening window portion 6 is opened on the back side of the enclosed concave chamber 4, and the variable display device 7 faces the opening window portion 6 from behind, and is schematically configured. The armor portion 21 of the center case 5 is provided with a decorative lamp 24 projecting from the armor portion 21 toward the game area 3 side.

  The bottom 23 of the center case 5 has a ball rolling surface 27 capable of rolling a game ball, and a ball guide path (so-called warp flow path) 28 for guiding the game ball from the game area 3 to the ball rolling surface 27. A horizontally long rotation unit 29 and a rotation unit mounting base 30 that rotatably supports the rotation unit 29. The ball rolling surface 27 is inclined downward from the side portions 22 toward the center in the left-right direction, and is formed with a depth that allows the game ball to roll in the front-rear direction. A drop prevention protrusion 31 is provided at the front end (end on the surface side of the game board 1) so as not to drop from the middle of the downward inclination (see FIGS. 11C and 11D). A recess 32 that can guide the game ball to the lower start winning opening 8 is provided in a substantially downwardly inclined state in the lowermost portion of the lower slope. The ball guide path 28 is provided between the bottom 23 of the center case 5 and the side part 22 (the left side part 22 in the present embodiment), and the inlet 28a is provided on the side (left side) of the center case 5. ), The exit 28b is opened to the upper part of the inclined surface on the left side of the ball rolling surface 27, respectively.

Next, the rotation unit 29 will be described.
The rotation unit 29 sucks and holds the game ball on the outer peripheral surface, and allows the game ball to be transferred by being driven to rotate in this holding state. As shown in FIG. 4, the rotating unit 29 includes a rotating shaft 40, a magnetic body (permanent magnet) 41 that can attract a game ball, and a horizontally long cylindrical rotating member 42 that includes the magnetic body 41. It is roughly composed of Then, as shown in FIG. 3 (a), in a state of being supported laterally in front of the rotating unit mounting base 30, a predetermined distance (specifically, from the diameter of the game ball) above the ball rolling surface 27. Are arranged at a wide interval) and are configured to rotate up and down when viewed from the front. Specifically, bearing sleeves 43 are fitted to both end portions of the rotation shaft 40, a rotation gear 44 is provided on the right end of the rotation shaft 40, and the bearing sleeve 43 is attached to the left and right sides of the rotation unit mounting base 30. The rotary gear 44 is connected to a rotary drive source 46 such as a stepping motor via a drive gear 47 while being loosely fitted to the bearing portions 45 on both sides.

  The rotation member 42 is fixed (locked) to the rotation shaft 50 on both the left and right sides of the rotation base 50 by restricting the position of the rotation base 50. And a regulating member cover 52 that covers the regulating member 51. The rotation base 50 is configured by disposing a short cylindrical reference rotation base 53 at the center in the axial direction and connecting an elongated cylindrical extension rotation base 54 to the left and right sides of the reference rotation base 53. Has been. Further, as shown in FIG. 5, locking portions 55 are provided projecting laterally at both left and right ends of the reference rotation base 53, and the inner ends of the extension rotation base 54 (on the reference rotation base 53). A concave locking receiving portion 56 for locking the locking portion 55 is formed at the opposing end portion (hereinafter referred to as the inner end). Then, the locking portion 55 is locked to the locking receiving portion 56 and the reference rotation base 53 and the extended rotation base 54 are connected, so that the extension rotation base 54 is connected to the reference rotation base 53. And can be positioned. By connecting the reference rotation base 53 and the extended rotation base 54 in this manner, the length of the rotation base 50 can be easily extended. Furthermore, the arrangement range of the magnetic body 41 to be described later can be expanded, and the game ball can be made to behave in a complicated manner to enhance the interest of the game. The detailed structure of the reference rotation base 53 and the extended rotation base 54 will be described later.

  The restricting member 51 engages with a notch 40a formed in the rotation shaft 40, and also has an outer end of the extended rotation base 54 (an end opposite to the reference rotation base 53. Hereinafter, an outer end). The rotation base 50 is prevented from moving in the longitudinal direction of the rotation shaft 40. Further, the left restricting member 51 hooks a rotation restricting claw 51 a protruding toward the extended rotation base 54 on the outer end of the extended rotation base 54, so that the rotation base 50 is rotated around the rotation shaft 40. Rotation is also restricted.

  The regulating member 51 of this embodiment is covered with a regulating member cover 52 from the side opposite to the rotating base 50. The restricting member cover 52 has a cylindrical shape that increases in diameter from the substantially same diameter as the rotating base body 50 toward the bearing portion 45, and is fixed to the rotating base body 50 by a fastening member (screw) 57. Thus, the rotating base 50 is integrated with the outer peripheral surface. Note that the attaching means of the restricting member cover 52 is not limited to the use of the fastening member 57. For example, as shown in FIG. The locking piece 58 is locked to a locking piece receiving portion 59 in which a part of the outer peripheral portion of the extending rotation base 54 is recessed, and the restricting member cover 52 is fixed to the rotation base 50. You may attach to.

Next, the reference rotation base 53 and the extended rotation base 54 will be described.
First, a structure for housing the magnetic body 41 of the extending rotation base 54 will be described. Note that the extended rotation bases 54 on both sides are symmetrical and have the same basic structure, and therefore the right extension rotation base 54 will be described as an example. As shown in FIG. 7A, the extending rotation base 54 is formed by forming recesses 62 in a rectangular shape on both the inner end and the outer end passing through the rotation shaft 40. A disk-shaped magnetic body 41 is accommodated in 62. The storage recess 62a at the inner end and the storage recess 62b at the outer end are formed at positions shifted in phase when viewed from the outside in the central axis direction (right side in the drawing) of the extended rotation base 54. More specifically, the inner end storage recess 62a is formed at a position shifted in phase by approximately 90 degrees counterclockwise from the outer end storage recess 62b (see FIG. 7B). Therefore, as shown by the arrow in the figure, when the turning unit 29 is turned so that the front side moves from the bottom to the top, the inner end receiving recess 62a moves following the outer end receiving recess 62b. Thus, since the extending rotation base 54 is provided with the storage recess 62 at the side end portion, the opening edge that becomes a fragile portion of the storage recess can be shifted from the outer peripheral surface portion where the game ball easily contacts. Accordingly, it is possible to suppress a problem that the rotating member 42 is damaged by the contact of the game ball, and the magnetic body 41 is disposed at a desired position of the rotating member 42 without worrying about the damage of the rotating member 42. be able to. Further, the magnetic body 41 can be accommodated without requiring extra part division or attaching a seal to the surface. Therefore, it is possible to prevent the structure for housing the magnetic body 41 of the rotating member 42 from becoming complicated, and to reduce the manufacturing cost.

The inner end receiving recess 62 a is closed at the opening by the side end of the reference rotation base 53. Further, the opening of the outer end storage recess 62 b is closed by the restriction member 51. Therefore, it is not necessary to prepare a special member for pressing the magnetic body 41, and the magnetic body 41 can be stored with a simple configuration.
In the present embodiment, the magnetic body 41 (outer magnetic body 41b) housed in the outer end housing recess 62b is set stronger than the magnetic body 41 (inner magnetic body 41a) housed in the inner end housing recess 62a. Has been. Further, the attracting state of the game ball by the magnetic body 41 will be described in detail later.

  Further, the extended rotation base 54 is provided with a ball movement guide 64 made of a groove or a protrusion on the outer peripheral surface along the axial direction of the extension rotation base 54, and the adsorbed game ball is the longitudinal length of the rotation base 50. It is configured to easily move in the direction. Further, the extended rotation base 54 has a ball engaging recess 65 that can engage a part of the game ball with a predetermined portion of the outer peripheral surface. More specifically, a ball engaging recess 65 (hereinafter referred to as an outer ball engaging recess 65s) provided in the extended rotation base 54 is substantially the center in the longitudinal direction of the extended rotation base 54 and extends. The rotation base 54 is formed at a position shifted by approximately 180 degrees from the outer end receiving recess 62b as viewed from the central axis direction, and at a position shifted by approximately 90 degrees counterclockwise from the inner end receiving recess 62a. (See FIG. 7B). The outer sphere engaging recess 65s of the present embodiment is formed by cutting out the outer periphery of the extending rotation base 54 along the longitudinal direction and extending the portion up to the middle of the notch from the restricting member cover 52. However, the present invention is not limited to this, and it may be formed only by being dented to a size that allows a game ball to be engaged.

  The reference rotation base 53 is also formed with a sphere engaging recess 65 (hereinafter, center sphere engaging recess 65c). As shown in FIGS. 4 and 7B, the central sphere engaging recess 65c is substantially the center in the axial direction on the outer peripheral surface of the reference rotation base 53, and is approximately 180 from the inner end storage recess 62a. It is arranged at the position where the phase is shifted.

  Therefore, when the rotation unit 29 is rotated so as to move the front side of the rotation member 42 from the bottom to the top, the outer end storage recess 62b, the inner end storage recess 62a, and the outer ball base of the extended rotation base 54 are provided. The joint recess 65s and the center sphere engagement recess 65c are rotated in the rotation direction in this order.

Next, the part located behind the rotation unit 29 in the rotation unit mounting base 30 will be described.
As shown in FIG. 3, the rotating unit mounting base 30 has a plurality of (four in this embodiment) horizontally long projections 68 arranged side by side at a predetermined interval on the upper rear side of the rotating unit 29. It protrudes at. The protrusion 68 is for detaching the game ball attracted to the magnetic body 41 from the attracting position of the rotating member 42 and guiding it in the lateral direction (the axial direction of the rotating member 42). The game balls are respectively arranged on the transfer trajectory of the game balls attracted to the magnetic body 41 corresponding to the magnetic body 41 of the rotation unit 29. And the center part protrudes toward the front, The left and right both sides are provided with the inclination part 68a inclined down toward back (refer FIG.3 (b)). Note that the detaching action of the game ball by the protrusion 68 will be described in detail later.

  Further, the game ball is moved from the upper side to the lower side of the rotating unit 29 at each position where the ball engaging recesses 65 of the rotating base body 50 can face each other during the rotation. A vertically long sphere introduction path 70 that can be introduced is provided. The ball introduction path 70 is provided between the adjacent protrusions 68 and has a game ball introduction port 70a at the tip of the lower end of the inclined portion 68a (see FIGS. 9 and 11). Further, the distance between the upper edge of the introduction port 70a and the outer peripheral surface of the rotating base 50 is smaller than the diameter of the game ball, and the distance between the upper edge of the introduction port 70a and the bottom of the ball engaging recess 65 is a game ball. It is set to be wider than the diameter. Therefore, only the game ball engaged with the ball engaging recess 65 is introduced into the introduction port 70a, and for the game ball not engaged with the ball engagement recess 65, the upper part of the game ball is held at the upper end of the introduction port 70a. It is configured not to be introduced into the ball introduction path 70.

  The two right and left ball introduction paths 70 (the ball introduction path located behind the extended rotation base 54; hereinafter, the outer ball introduction path 71) have the game ball outlet 70b behind the ball rolling surface 27. (See FIGS. 11 (c) and 11 (d)). A central ball introduction path 70 (a ball introduction path located behind the reference rotation base 53. Hereinafter, a start winning introduction path 72) has a start winning outlet 73 that serves as a gaming ball outlet. 27, is opened in front of the bottom 23 of the center case 5 and directly above the start winning opening 8 (see FIG. 9). Therefore, it can be derived directly above the start winning opening 8, and the introduced game ball is configured to easily win the starting winning opening 8.

  Next, the operation of the rotation unit 29 will be described. The rotation unit 29 is rotated forward by 157 degrees so that the front side of the outer peripheral surface of the rotation base 50 is moved upward by the rotation drive source 46, and so that the front side of the outer peripheral surface is moved downward. The reverse rotation that rotates 30 degrees is always repeated.

  First, when a game ball flowing down the game area 3 passes through the ball guide path 28 or is hit by a nail below the center case 5 and reaches the ball rolling surface 27, the game ball is shown in FIG. Thus, the ball rolling surface 27 flows down toward the center in the left-right direction. At this time, if none of the magnetic bodies 41 is located at the position facing the ball rolling surface 27, the game ball reaches the recess 32 or passes through the recess 32 and is on the opposite side (right side in the figure). After the ball rolling surface 27 is folded back, it reaches the recess 32 again, rolls forward from the recess 32 and falls downward from the center case 5. The game balls that have fallen are subjected to the inertial force in the lateral direction that has moved on the ball rolling surface 27, so that they deviate from immediately above the start winning opening 8, and are hit by the life nail 12. It is difficult to win a prize (see FIG. 10B).

  In addition, when the outer magnetic body 41b of the outer end storage recess 62b is at a position facing the ball rolling surface 27 (lower part of the rotation unit 29), the game ball is attracted to the outer magnetic body 41b to roll the ball. It is attracted to the rotating member 42 from the surface 27 and is transferred in the rotating direction of its peripheral surface by the rotation of the rotating member 42. Then, the game ball adsorbed by the rotating member 42 rises while repeating the up-and-down movement along with the normal rotation and reverse rotation of the rotating member 42 (FIG. 11A), and eventually toward the rotating unit mounting base 30. Then, it moves rearward and comes into contact with the protrusion 68 (FIG. 11B). Further, when the rotation unit 29 is rotated forward, the game ball is pushed by the protrusion 68 and is attracted by the magnetic force of the outer magnetic body 41b, but approaches the front of the outer ball introduction path 71 by the inclined portion 68a of the protrusion 68. That is, it is guided in the axial direction of the rotating member 42 (FIG. 10A). The game ball guided forward of the outer ball introduction path 71 may slide down the front side of the rotation member 42 due to the reverse rotation of the rotation unit 29, but the upper part of the game ball is introduced into the outer ball introduction path 71. It is held at the upper edge of the opening 70a and temporarily stopped between the rotating unit 29 and the rotating unit mounting base 30 (FIG. 11 (c)).

  The stopped game ball is attracted to the inner magnetic body 41a of the inner end accommodating recess 62a that moves following the outer magnetic body 41b, and moves again in the axial direction of the rotating member 42, and is attracted to the inner magnetic body 41a. Is done. At this time, the rotation unit 29 may reverse and the game ball may be attracted to the outer magnetic body 41b or slide down the front side of the rotation member 42. However, the rotation unit 29 has a high forward rotation ratio. Since it is set, the game ball is attracted to the inner magnetic body 41a with a high probability. Then, it comes into contact with the protrusion 68 positioned behind the inner magnetic body 41a (FIG. 11E), and when the rotating unit 29 rotates forward in this contact state, the game ball is pushed by the protrusion 68, While being attracted by the magnetic force of the inner magnetic body 41a, the axial direction of the rotating member 42 by the inclined portion 68a of the protrusion 68, specifically, the direction returning to the front of the outer ball introduction path 71 or the direction approaching the start winning introduction path 72. (FIG. 8).

  When the game ball returns to the front of the outer ball introduction path 71, the outer ball engagement recess 65s moving after the inner end storage recess 62a sinks below the game ball and engages the lower part of the game ball. (FIG. 11 (d)). Then, since the game ball descends, the upper part of the game ball and the introduction port 70a are detached, and when the rotation unit 29 rotates forward in this engaged state, the game ball is moved rearward from the outer ball engagement recess 65s. While rolling, it is introduced into the outer ball introduction path 71 and falls onto the ball rolling surface 27. The dropped game ball flows down on the ball rolling surface 27.

  On the other hand, when the game ball moves to the front of the start winning introduction path 72, the game ball may slide down on the front side of the rotation member 42 due to the reverse rotation of the rotation unit 29. The upper part is held at the upper edge of the introduction opening 70a of the start winning introduction path 72, and is temporarily stopped between the turning unit 29 and the turning unit mounting base 30 in front of the starting winning introduction path 72 (FIG. 9A). )). When the central ball engaging recess 65c moves to the lower side of the game ball, the lower portion of the game ball is engaged (FIG. 9B). Then, since the game ball descends, the upper part of the game ball and the introduction port 70a are disconnected, and when the rotation unit 29 rotates forward in this engaged state, the game ball is moved backward from the central ball engaging recess 65c. It rolls and is introduced into the start winning introduction path 72, falls below the center case 5 from the start winning deriving port 73, and has a high probability of winning the start winning port 8 directly below. Thus, the possibility that the game ball transferred by the turning unit 29 wins the start winning opening 8 can be increased, and the player's sense of expectation for winning can be increased.

  Further, the turning unit 29 moves the game ball that rolls on the ball rolling surface 27 with the force of passing through the ball guide path 28 from the game area 3 or jumping with a nail below the center case 5. Based on the rotation of the moving unit 29, it can be changed to a moving state in the vertical direction different from rolling, that is, in the circumferential surface direction of the rotating member 42, or in the axial direction of the rotating member 42. . Therefore, the complicated movement of the game ball can be shown to the player, and the interest of the game can be further enhanced. Further, the game ball transferred by the rotation unit 29 is caused to flow down to the rear ball introduction path 70 and guided to the lower side of the ball rolling surface 27 or the center case 5, so that the game ball is moved to the rear of the rotation unit 29. It is possible to hide and reappear below the rotating unit 29. Therefore, the player can enjoy watching the behavior of the game ball and improve the interest of the game.

  In addition, although the rotation unit 29 of the said embodiment formed the storage recessed part 62 in the side edge part of the rotation base | substrate 50, and accommodated the magnetic body 41, this invention is not limited to this. For example, the rotating unit 77 of the modification shown in FIG. 12 houses the magnetic body 41 by incorporating the magnetic body 41 into the core member and storing the core material in a circular tubular cover.

  Specifically, the rotation unit 77 which is a modification of the first embodiment includes a rotation shaft 40, a magnetic body 41 that can attract a game ball, and a horizontally long cylindrical rotation that contains the magnetic body 41. The moving member 78 is generally configured. The rotating member 78 is fixed to the rotating shaft 40, an inner rotating member 79 that is passed through the rotating shaft 40 and functions as a cylindrical core member, an outer rotating member 80 that functions as a tubular cover, and the like. And a restricting member 81 for restricting the positions of the inner turning member 79 and the outer turning member 80. The inner turning member 79 has protruding portions 82 protruding from the circumferential surface (outer circumferential surface) along the axial direction, and a plurality of the protruding portions 82 are equally distributed in the circumferential direction (four in this modification). Provided. In addition, the protruding portion 82 is formed with a magnetic body accommodation hollow portion 83 in which the magnetic body 41 is arranged by cutting out an intermediate portion in the longitudinal direction. In the present modification, the protrusion 82 that protrudes in the right direction in the figure is formed with one magnetic material accommodation space 83 at a position near both ends of the inner turning member 79, and in the upward direction in the figure. In the projecting portion 82 projecting to the left, two magnetic material housing empty portions 83 are formed at a position near the center in the longitudinal direction of the inner turning member 79.

  The outer rotation member 80 is closed at one end (right end in the figure) in a state where the end of the rotation shaft 40 can pass therethrough, and the other end (left end in the figure) is used as an inlet for accommodating the inner rotation member 79. The inner opening member 79 is opened and accommodated from the rotation center direction. And the groove part 84 which can fit the protrusion part 82 of the inner side rotation member 79 is formed in the inner peripheral surface along the axial direction. Therefore, when the inner turning member 79 is housed in the outer turning member 80, the open portion of the magnetic material accommodation space 83 is closed by the groove 84, and the magnetic material 41 is held in the magnetic material accommodation space 83. Note that a spherical engagement recess (not shown) that can face the spherical introduction path 70 of the rotary unit mounting base 30 is formed on the outer peripheral surface of the outer rotary member 80.

  The restricting member 81 is a substantially semi-disc-shaped member that is engaged with a notch 40 a formed on the rotating shaft 40. The regulating member 81 is fastened by a fastening member 85 in a state of being sandwiched between one end face (right end face in the drawing) of the inner turning member 79 and the inside of the closed portion of the outer turning member 80. Thus, the positions of the inner turning member 79, the outer turning member 80, and the turning shaft 40 are restricted.

  The rotating member 78 as described above can be configured with a simple structure, and it is not necessary to use a small part for holding the magnetic body 41, and the disadvantage that the number of parts increases can be suppressed. In addition, the magnetic body 41 can be set to be disposed at a desired position simply by changing the formation location of the magnetic body housing empty portion 83 in the protruding portion 82 of the inner turning member 79. Moreover, the assembly work of the magnetic body 41 can be simplified, and the production efficiency of the rotating unit can be improved.

  In addition, although the rotation member 78 of the modification has fixed the inner side rotation member 79 and the outer side rotation member 80 to the control member 81, it is not limited to this. Specifically, as shown in FIG. 13, the regulating member 81 and one end (the left end in the drawing) of the inner turning member 79 are fastened, and the other end (the right end in the drawing) of the inner turning member 79 is fixed. The outer rotating member 80 may be assembled while being fixed to the inside of the closed portion. When the rotating member 78 is assembled in this way, it is possible to prevent the load associated with the positioning of the rotating members 79 and 80 from being concentrated on the restricting member 81 and to make it difficult to damage the restricting member 81. Therefore, it is possible to reduce the labor for maintenance work of the rotating member 78.

  By the way, although the rotation unit of the above-described embodiment includes the horizontally-oriented cylindrical rotation member, the present invention is not limited to this, and may include a vertically-oriented cylindrical rotation member. For example, the center case 5 in the second embodiment shown in FIG. 14 is basically the same as that in the first embodiment, but the configurations of the rotating unit and the rotating unit mounting base are different. That is, the center case 5 of the second embodiment is provided with a plurality of (three in this embodiment) rotation units 89 each having a vertically-oriented cylindrical rotation member 88 arranged side by side at one end (the left end in the figure). The game unit adsorbed by the arranged rotation unit 89 is adsorbed close to the adjacent rotation unit 89 by rotating each rotation member 88 and is arranged at the other end (right end in the figure). 89, and is further introduced from the rotation unit 89 at the other end into the start winning introduction path 90 opened beside it. More specifically, a plurality of substantially rectangular openings 92 (in the present embodiment, on the front surface of the rotating unit mounting base 91 (in other words, the surface that can face the game ball rolling on the ball rolling surface 27)). 3 places) Opened side by side and at the side of the opening 92 that is farthest from the ball guide path 28 (the opening 92 on the right side in the figure) opposite to the ball guide path 28 (in the figure) On the right side), an opening 90a of the start winning introduction path 90 is opened. Further, a rotation unit 89 is provided at the rear of each opening 92, and a front outer peripheral surface of the rotation member 88 is provided facing the opening 92.

  The rotating unit 89 rotates the outer peripheral surface of the rotating member 88 facing the opening 92 from the spherical guiding path 28 side to the introduction port 90a side, that is, from the left side to the right side. As shown in FIG. 16, the rotary shaft 93, the magnetic body 41 that can attract the game ball, and a cylindrical rotary member 88 that contains the magnetic body 41 are schematically configured. A rotating gear (worm wheel) 94 is provided at the base end (left end in the figure).

  The rotation member 88 includes a rotation base 95 that is passed through the end of the rotation shaft 93 and a restriction member 96 that is fixed to the rotation shaft 93 and restricts the vertical position of the rotation base 95. ing. The rotation base 95 is formed with a plurality of storage recesses 97 in a rectangular shape at the lower end through which the end of the rotation shaft 93 passes, and the disk-shaped magnetic body 41 is stored in each storage recess 97. ing. Further, the restricting member 96 is provided with a closing piece 98 that closes the housing recess 97 protruding from the surface facing the rotating base 95. The closing piece 98 is formed in such a length that it abuts against the magnetic body 41 in the storage recess 97 and has a function of preventing the magnetic body 41 from rattling in the storage recess 97. In this embodiment, the storage recesses 97 are formed at two locations in a state of being opposed to each other with the rotation shaft 93 interposed therebetween, that is, in a state where the phase is shifted by 180 degrees around the rotation shaft 93. It is not limited to the angle of deviation. For example, the storage recesses 97 may be formed at three positions with a phase shift of 120 degrees, and the three magnetic bodies 41 may be stored in the rotating base 95.

  Each rotation unit 89 meshes the rotation gear 94 with one of a plurality of (three) worm gears 102 fixed to the lateral drive transmission shaft 101 with a set screw. It is connected to a rotational drive source 104 such as a stepping motor via a drive gear 103. Accordingly, each rotation unit 89 is configured to rotate all at the same time when the rotation drive source 104 is driven. Each of the worm gears 102 is set to a gear ratio different from that of the other worm gears 102, and the rotation period of each rotation unit 89 is configured to be different from the rotation period of the other rotation unit 89.

  Further, the rotating unit mounting base 91 brings the lower edge of the opening 92 (the opening 92L on the left side in the figure) close to the ball guide path 28 close to the ball rolling surface 27 and the upstream side of the ball rolling surface 27 is positioned on the upstream side. The rolling game ball is configured to be easily attracted to the left rotation unit 89L. Then, as shown in FIG. 15, the protruding wall 105 protrudes forward between the lower edges of the openings 92 so that the game ball detached from the rotating unit 89 can be prevented from immediately falling downward. It is configured. Further, in front of the introduction port 90a, a guide shelf 106 for guiding the game ball detached from the left turn unit 89 to the introduction port 90a is provided in a state of being inclined downward toward the introduction port 90a. ing.

Next, the operation of the rotation unit 89 and the rotation unit mounting base 91 having the above-described configuration will be described. Each rotation unit 89 is always rotated so that the front side of the outer peripheral surface of the rotation member 88 moves from left to right.
When a game ball is guided from the ball guide path 28 to the ball rolling surface 27, the game ball flows down on the ball rolling surface 27 toward the center. At this time, the rotation unit 89L arranged on the left side (upstream side of the transfer) has a portion corresponding to the storage recess 97 on the outer peripheral surface of the rotation member 88 (a portion indicated by a vertical double line in the drawing. When the magnetic material storage portion is not exposed from the left opening 92L, the game ball flows down the ball rolling surface 27 as it is and falls downward from the recess 32 in the central portion.

  On the other hand, when the magnetic material storage portion is exposed from the left opening 92L, the left rotation unit 89L attracts the game ball with high probability. The adsorbed game ball is transferred from the left side to the right side, that is, in the rotation direction of the outer peripheral surface of the rotation member 88 as the left rotation unit 89L rotates. When the game ball reaches the side edge (right side edge) of the left opening 92L, the game ball is attracted by the magnetic force of the magnetic body 41, but is detached from the rotating member 88 and slightly falls. , It hits the protruding wall 105 between the left rotation unit 89L and the center (transfer intermediate) rotation unit 89C (see FIG. 18).

  At this time, if the magnetic material storage portion of the central rotation unit 89C does not face the left side of the central opening 92C, the game ball falls as it is and moves from the ball rolling surface 27 to the game area 3 below. Flow down. On the other hand, when the central turning unit 89C has the magnetic material storage portion just facing the left side (upstream side of transfer) of the central opening 92C, the game ball is attracted to the central turning unit 89C and left to right. The central opening unit 89C and the right side (transfer downstream side) rotation unit are separated from the rotation member 88 and slightly fall off at the right side edge (side edge on the transfer downstream side) of the central opening 92C. It hits the protruding wall 105 between 89R.

  When the magnetic material storage portion of the right rotation unit 89R does not face the left side of the right opening 92R, the game ball falls as it is and the game area 3 below the ball rolling surface 27 is dropped. Flow down. On the other hand, when the right rotating unit 89R faces the magnetic material storage portion to the left side of the right opening 92R, the game ball is attracted to the right rotating unit 89R and transferred from the left side to the right side. The right opening 92R is detached from the rotating member 88 at the right edge (side edge on the downstream side of the transfer), falls to the guide shelf 106, and rolls to the rear inlet 90a. The rolled game ball flows down the start winning opening 8 and falls below the center case 5 from the start winning deriving opening 73, so that it becomes easy to win the start winning opening 8 directly below.

  Thus, in the center case 5 of the second embodiment, the game ball can be transferred laterally by the plurality of rotation units 89 and guided to the start winning introduction path 90. Therefore, it is possible to enjoy the behavior of a game ball that has never existed and to enhance the interest of the game. Furthermore, it is possible to make it easier to win the game ball transferred by the turning unit 89 to the start winning opening 8 and to increase the player's expectation for winning.

  In the present embodiment, the plurality of rotation units 89 are rotationally driven by one rotation drive source 104 and one drive transmission shaft 101. However, the present invention is not limited to this, and each rotation unit 89 is provided for each rotation unit 89. A rotation drive source and a drive transmission shaft may be provided, and each rotation unit 89 may be independently rotated. Further, the rotation unit 89 is rotated in the forward direction in which the front peripheral surface of the rotation member 88 moves from the spherical guide path 28 side to the introduction port 90a side and in the reverse rotation in which the front peripheral surface moves from the introduction port 90a side to the spherical guide path 28 side. If combined and periodically rotated, it is easy to increase the interest of the game by realizing a more complex game ball behavior.

  Although the above-described embodiment has been described by taking the rotation unit provided in the center case 5 as an example, the rotation unit may be provided in the game area 3 other than the center case 5. Moreover, although the said embodiment demonstrated the example of the pachinko game machine which is a typical game machine, this invention is not restricted to this, The rotation unit which makes rolling of the game ball complicated in a game area | region is demonstrated. As long as the gaming machine is provided, it may be a gaming machine such as an enclosed ball-type pachinko machine, an arrangement ball type gaming machine, or a sparrow ball type gaming machine that circulates the game ball enclosed inside.
