  The present invention relates to a movable accessory device provided in a ball game machine, and more particularly to a movable accessory device in which a pair of slide plates can move in the proximity and separation directions in front of a display screen of a variable display device. Is.

  In some ball game machines represented by pachinko machines, a variable display device and a start prize opening are arranged in the game area of the game board, and the game balls launched toward the game area enter the start prize opening. There is a model in which electronic lottery is performed in response to this, and the variable display device performs variable display and stop display of symbols based on the lottery result. Electronic lottery results include winning (winning) and losing (non-winning). When the lottery results are winning, a special combination of symbols is displayed on the display screen of the variable display device. Transition to game mode. In this special game mode, for example, a game ball enters a big winning opening exposed by opening an attacker, so that the player can acquire many prize balls.

  In such a ball game machine, a movable body capable of changing the movable mode is arranged at an appropriate position in the game area (for example, around the variable display device), and it is movable to the player that the player is elected by electronic lottery. Movable accessory devices that are suggested by the manner in which the body moves are widely used. Such a movable accessory device includes an actuator composed of a motor, a solenoid, and the like, and a movable body that performs various motions using this actuator as a drive source. Conventionally, a variable display provided above the reel unit of the slot machine. There is known a movable accessory device in which a pair of slide plates are arranged on both the left and right sides of the device, and these slide plates are reciprocated in front of a display screen of a variable display device (see, for example, Patent Document 1).

  In the movable accessory device disclosed in Patent Document 1, a pair of slide plates and a pair of motors are disposed on both the left and right sides of the variable display device. Normally, these slide plates are in a retracted position that opens the front of the display screen. Is retained. A rack projecting sideways is provided on the upper or lower side of the slide plate, and a pinion attached to the output shaft of the motor meshes with the corresponding slide plate rack. When the pair of slide plates are in the retracted position, the pinion is meshed with the base end side of the rack, and when the motor is rotated in either the forward or reverse direction in this state, the meshed portion of the pinion and rack is moved from the base end side. As a result, the slide plates move from the retracted position toward the center of the display screen. Then, when the rotation of the motor is stopped at the close position where the opposing surfaces of the slide plates are in contact with each other, the front of the display screen is shielded by the pair of slide plates. Also, if the motor is rotated in the opposite direction when the pair of slide plates are in the close position, the meshing portion of the pinion and the rack moves from the front end side to the base end side, and accordingly both slide plates are moved from the close position. Since it moves in the direction of separation and stops at the retracted position, it returns to the retracted position where the front of the display screen is opened.

  Since the movable accessory device disclosed in Patent Document 1 is applied to a slot machine having a relatively large space, a pair of slide plates with racks protruding laterally are provided on both the left and right sides of the variable display device. Can be arranged without difficulty. However, in a pachinko machine in which the variable display device is arranged at the center of the game area of the game board, it is necessary to secure a flow area of game balls on both the left and right sides of the variable display apparatus, and therefore, disclosed in Patent Document 1. When the movable accessory device as described above is applied to a pachinko machine, particularly when applied to a pachinko machine equipped with a variable display device having a large display screen, a space for moving the slide plate is secured on both the left and right sides of the variable display device. It becomes difficult. In addition, since the movable accessory device is for instructing the player of the result of the electronic lottery, a wide variety of movement forms and directions are required. For example, the movable accessory device described above is used. There is a demand to realize novel movement by rotating in the forward and reverse directions in front of the variable display device, but in that case, it is not only difficult to secure the movement space of the slide plate, but also includes a pair of motors There is a new problem that it becomes difficult to rotate a plurality of heavy objects in both forward and reverse directions in a balanced manner.

  The present invention has been made in view of such a state of the art, and an object of the present invention is to make a pair of slide plates movable in the proximity and separation directions compact around a variable display device having a large display screen. An object of the present invention is to provide a movable accessory device that can be disposed and can stably rotate the slide plate and its drive mechanism in both forward and reverse directions.

  To achieve the above object, the present invention provides a movable accessory device that is arranged in front of a variable display device provided in a game area of a game board and suggests a result of an electronic lottery to a player in a movable manner. A rotary plate provided with a rectangular opening through which the display screen of the variable display device can be visually observed, and a rotation drive mechanism for rotating the rotary plate in both forward and reverse directions within a plane substantially parallel to the board surface of the game board; A first slide plate and a second slide plate arranged to face each other through the opening; a first screw shaft for reciprocating the first slide plate between one side portion and a central portion of the opening; and A first motor that rotationally drives the first screw shaft in both forward and reverse directions; a second screw shaft that reciprocally moves the second slide plate between the other side portion and the central portion of the opening; and the second screw Shi A second motor that rotates the shaft in both forward and reverse directions, and the first motor and the second motor are mounted on the rotating plate with a perpendicular passing through the rotation center of the rotating plate as an axis of symmetry, and The first screw shaft and the second screw shaft are supported by the rotating plate while being displaced in the front-rear direction on the same plane substantially orthogonal to the symmetry axis.

  In the movable accessory device configured as described above, an opening through which a display screen of the variable display device can be visually observed is provided on a rotating plate that is rotatable in a plane substantially parallel to the surface of the game board. A pair of slide plates arranged in opposition to each other is driven in the approaching / separating direction along the axial direction of the screw shaft, and the pair of screw shafts are substantially flush with the board surface of the game board. Since it is supported on the rotating plate while being displaced in the front-rear direction above, the pair of slide plates can be compactly arranged around the variable display device having a large display screen. In addition, a pair of motors that individually rotate and drive a pair of screw shafts are mounted on the rotating plate with a perpendicular passing through the rotation center of the rotating plate as an axis of symmetry, and a pair of slide plates and a pair of screws that are a driving mechanism thereof Since the shaft and the pair of motors are arranged on the rotating plate with a good weight balance, when the rotating plate is driven to rotate in either the forward or reverse direction by the rotating drive mechanism, the load torque applied to the rotating drive mechanism is the forward rotation direction. Thus, the entire rotating plate including the pair of slide plates and the driving mechanism thereof can be stably rotated.

  In the above configuration, the first motor and the second motor are arranged close to each other with the opposite output shaft sides facing each other, and the first screw shaft extends from the output shaft of the first motor toward the second motor side. When the second screw shaft is extended toward the first motor side from the output shaft of the second motor, the position of the pair of heavy motors (the first motor and the second motor) is placed on the rotating plate. Since the center of rotation is approached, the entire rotating plate can be rotated more stably. In this case, the rotating plate is driven to rotate in substantially the same amount in the forward direction and in the reverse direction with respect to the initial position, and the first motor and the second motor are located immediately below the center of the opening at the initial position of the rotating plate. It is preferable that the center of gravity of the entire rotating plate is located immediately below the center of the opening at the initial position.

  The movable accessory device of the present invention is provided with an opening through which a display screen of the variable display device can be viewed on a rotating plate that is rotatable in a plane substantially parallel to the surface of the game board. The pair of slide plates are driven in the approach and separation directions along the axial direction of the screw shaft, respectively, and the pair of screw shafts are front and rear on the same plane substantially orthogonal to the board surface of the game board. Since it is supported by the rotating plate while being displaced in the direction, the pair of slide plates can be compactly arranged around the variable display device having a large display screen. In addition, a pair of motors that individually rotate and drive a pair of screw shafts are mounted on the rotating plate with a perpendicular passing through the rotation center of the rotating plate as an axis of symmetry, and a pair of slide plates and a pair of screws that are a driving mechanism thereof Since the shaft and the pair of motors are arranged on the rotating plate with a good weight balance, when the rotating plate is driven to rotate in either the forward or reverse direction by the rotating drive mechanism, the load torque applied to the rotating drive mechanism is the forward rotation direction. Thus, the entire rotating plate including the pair of slide plates and the driving mechanism thereof can be stably rotated.

It is exposed inside. A fall prevention piece 24 is integrally formed at the center of the lower side of the support base 22, and a pair of photo interrupters 25 and 26 are mounted obliquely above the fall prevention piece 24. The fall prevention piece 24 is positioned on a vertical line L that passes through the rotation center O of the rotating plate 23, and a pair of stopper protrusions 27 and 28 that are opposed to each other through the vertical line L are provided at the center of the upper side of the support base 22. ing. A drive motor 29 is attached to the lower side of the support base 22, and a reduction gear train 30 is disposed in the vicinity of the drive motor 29. The reduction gear train 30 is composed of a plurality of gears including a first gear 30 a fixed to the output shaft of the drive motor 29, and the final gear 30 b of the reduction gear train 30 is located in the vicinity of the fall prevention piece 24. Yes. Further, a cable guide 31 to be described later is fixed to the right side portion of the support base 22 by screws or the like, and one end of a strip-shaped flat cable 32 is connected to the cable guide 31 by a connector. The inner wall surface of the cable guide 31 and the outer peripheral edge of the rotating plate 23 are opposed to each other via an arcuate space S, and the flat cable 32 has a U-shaped reversing portion 32a in the arcuate space S. Has been placed.

  As shown in FIGS. 7 and 8, a rectangular opening 33 is formed at the center of the synthetic resin rotating plate 23, and the display screen 14 a of the variable display device 14 can be seen through the opening 33. ing. The upper portion of the rotating plate 23 is a small diameter portion 23a, and the small diameter portion 23a and the large diameter portion 23b below the small diameter portion 23a are continuous via a pair of left and right flat portions 23c. A pair of guide holes 23e are formed below the small diameter portion 23a, and these guide holes 23e extend in the left-right direction along the upper side of the opening 33. Further, a thin portion 23d is formed on the outer peripheral edges of the small diameter portion 23a and the large diameter portion 23b, and the thin plate portion 23d is supported by three rollers 34 as shown in FIG. Is rotatably supported on the support base 22 via each roller 34. All of these rollers 34 have a double roller structure, which will be described later. Hereinafter, this double roller structure will be described by taking as an example a roller 34 that supports the lower left portion of the rotating plate 23.

  As shown in FIG. 6, the roller 34 that supports the lower left portion of the rotating plate 23 includes an upper roller half 34a and a lower roller half 34b that sandwich the thin portion 23d of the rotating plate 23 in the plate thickness direction. The upper roller half 34 a and the lower roller half 34 b are coaxially arranged on a support shaft 35 planted on the support base 22, and are supported rotatably about the support shaft 35. However, a gap S1 is formed between the outer peripheral end of the thin portion 23d and the shaft portion of the upper roller half 34a, and the thin portion 23d is in the radial direction with respect to the upper roller half 34a and the lower roller half 34b. Contactless. The roller 34 that supports the lower right portion of the rotating plate 23 has the same configuration. When the left and right lower portions of the rotating plate 23 are supported by the roller 34 having the double roller structure, the upper roller half 34a having a large diameter and the lower It is possible to rotate the rotating plate 23 smoothly by reducing the frictional resistance generated between the rotating plate 23 and the roller 34 after the rotating plate 23 is reliably supported by the side roller half-off 34b. The remaining roller 34 that supports the central upper portion of the rotating plate 23 has a similar double roller structure with a slightly smaller diameter. However, since the weight of the rotating plate 23 does not act on the roller 34 at the upper center, the roller 34 does not necessarily have a double roller structure, and a general single roller structure roller can also be used.

  As shown in FIG. 3, a ring gear 36 is attached to the lower outer peripheral edge on the surface side of the rotating plate 23, and the final gear 30 b of the reduction gear train 30 described above is a perpendicular line passing through the rotation center O of the rotating plate 23. Engage with the ring gear 36 in the vicinity of L. As a result, the rotation of the drive motor 29 is transmitted to the rotating plate 23 via the reduction gear train 30, and the drive motor 29, the reduction gear train 30 and the ring gear 36 constitute a rotation drive mechanism. In the case of this embodiment, the rotary drive mechanism rotates the rotary plate 23 by about 45 degrees in both forward and reverse directions (clockwise and counterclockwise) with reference to the initial position. The rotation angle of the rotating plate 23 in the clockwise direction is regulated by the left flat portion 23c coming into contact with one stopper projection 27, and the rotation angle of the rotating plate 23 in the counterclockwise direction is controlled by the right flat portion 23c. It is regulated by coming into contact with the other stopper projection 28. Further, the outer peripheral edge of the rotating plate 23 and the above-described drop prevention piece 24 are opposed to each other with a predetermined interval, so that the fall prevention piece 24 does not hinder the rotation operation of the rotation plate 23. However, when the roller 34 supporting the rotating plate 23 is damaged or the rotating plate 23 is detached from the roller 34 due to an external impact or the like, the outer peripheral edge of the rotating plate 23 contacts the upper end of the fall prevention piece 24. Since the further movement is restricted at the time, the fall accident of the rotating plate 23 can be surely prevented.

  As shown in FIG. 8, a light shielding plate 37 is attached to the outer peripheral edge on the back surface side of the rotating plate 23, and a short light shielding wall 37a and a long light shielding wall 37b stand up concentrically on the light shielding plate 37. It is installed. The pair of photo interrupters 25 and 26 described above are located on the rotation locus of the light shielding walls 37a and 37b, and the initial position and the rotation direction of the rotating plate 23 can be detected based on the output signals of both the photo interrupters 25 and 26. It is like that. Specifically, when the rotating plate 23 is in the initial position, the short light shielding wall 37a is in a position crossing the optical path of one photointerrupter 25, and the long light shielding wall 37b crosses the optical path of the other photointerrupter 26. Since it is in the position, both of the photo interrupters 25 and 26 output off signals. Further, when the rotating plate 23 rotates clockwise from the initial position, the short light shielding wall 37a moves to a position deviating from the optical path of one photointerrupter 25, and the long light shielding wall 37b also moves from the optical path of the other photointerrupter 26. In order to move to a position that deviates, both of the photo interrupters 25 and 26 output ON signals. On the contrary, when the rotating plate 23 rotates counterclockwise from the initial position, the short light shielding wall 37a moves to a position out of the optical path of one photo interrupter 25, while the long light shielding wall 37b moves to the other photo interrupter. In order to move in the optical path 26, an on signal is output from one photo interrupter 25 and an off signal is output from the other photo interrupter 26.

  As shown in FIG. 3, most of the front surface of the rotating plate 23 is covered with a synthetic resin decorative cover 38, and the decorative cover 38 has a rectangular window having the same size as the opening 33 of the rotating plate 23. A hole 39 is provided. As shown in FIG. 9, the decorative cover 38 is integrally formed with a peripheral wall 38a surrounding the window hole 39 vertically and horizontally, and the rotating plate 23 and the decorative cover 38 are screwed at a plurality of locations including the vicinity of the peripheral wall 38a. By doing so, an integrated product of the rotary plate 23 and the decorative cover 38 having a high mechanical strength as a whole is configured.

  As shown in FIG. 4, a pair of slide plates 40 and 41 are mounted on the back surface of the rotating plate 23. For convenience, the sliding plate 40 positioned on the left side when viewed from the front of the rotating plate 23 is a first slide plate, When the slide plate 41 located on the right side is called a second slide plate, the first slide plate 40 and the second slide plate 41 are opposed to each other on the left and right sides through the opening 33. The first slide plate 40 and the second slide plate 41 are movable bodies simulating doors and are not shown in the figure, but a plurality of LEDs are mounted inside these slide plates 40 and 41. Further, on the rear surface of the rotating plate 23, a first motor 42 and a first screw shaft 43 that are driving mechanisms of the first slide plate 40, and a second motor 44 and second screw that are driving mechanisms of the second slide plate 41 are provided. Each shaft 45 is mounted.

  A pinion 46 is fixed to the output shaft of the first motor 42, and a pinion 47 is fixed to the output shaft of the second motor 44. The first motor 42 and the second motor 44 are attached at positions having a perpendicular line L passing through the rotation center O of the rotating plate 23 as an axis of symmetry. As shown in FIGS. The two motors 44 are arranged close to each other with their opposite output shaft sides facing each other.

  The first screw shaft 43 and the second screw shaft 45 are arranged in parallel along the lower side of the opening 33, and the first screw shaft 43 and the second screw shaft 45 are on the same plane orthogonal to the perpendicular L. The position is shifted in the front-rear direction, and the right side portion of the first screw shaft 43 and the left side portion of the second screw shaft 45 overlap in the front-rear direction. A pinion 48 is fixed to one end portion of the first screw shaft 43, and the rotation of the first motor 42 is connected to the first screw shaft 43 by connecting the pinion 48 and the pinion 46 via a relay gear 49. It is to be transmitted. Further, a pinion 50 is fixed to one end of the second screw shaft 45. By connecting the pinion 50 and the pinion 47 via the relay gear 51, the rotation of the second motor 44 is rotated to the second screw shaft 45. 45 is transmitted. That is, the first screw shaft 43 extends from the output shaft of the first motor 42 toward the second motor 44, and the second screw shaft 45 extends from the output shaft of the second motor 44 toward the first motor 42. I'm out.

  A guide cylinder 52 is attached to the lower end portion of the first slide plate 40, and the guide cylinder 52 is fitted into the first screw shaft 43. A protrusion (not shown) that engages with the spiral groove of the first screw shaft 43 is formed on the inner peripheral surface of the guide cylinder 52, and the first slide plate 40 is rotated with the rotation of the first motor 42. Reciprocates in the axial direction of the first screw shaft 43 (X1-X2 direction). A protrusion 40a bent in an L shape is integrally formed at the upper end of the first slide plate 40, and this protrusion 40a slides on the upper wall of one guide hole 23e formed in the rotating plate 23. Engageable (see FIG. 9). That is, the driving force of the first motor 42 is applied only to the first slide plate 40 from the lower end side, and the upper end side is a free end to which no driving force is applied, and a small magnet is provided on the end surface on the free end side. 53 is fixed.

  Similarly, a guide cylinder 54 is attached to the lower end portion of the second slide plate 41, and the guide cylinder 54 is fitted into the second screw shaft 45. A protrusion (not shown) that engages with the spiral groove of the second screw shaft 45 is formed on the inner peripheral surface of the guide cylinder 54, and the second slide plate 41 is rotated with the rotation of the second motor 44. Reciprocates in the axial direction (X1-X2 direction) of the second screw shaft 45. A protrusion 41a bent in an L shape is integrally formed at the upper end of the second slide plate 41, and this protrusion 40a slides on the upper wall of the other guide hole 23e formed in the rotary plate 23. Engagement possible. That is, the driving force of the second motor 44 is applied only to the second slide plate 41 from the lower end side, and the upper end side is a free end to which no driving force is applied. A magnetic body 55 is attached.

  As shown in FIG. 12, the first slide plate 40 and the second slide plate 41 are in the retreat positions that are most separated in the normal gaming state, and in this case, the opening 33 of the rotating plate 23 is fully opened. When the first motor 42 and the second motor 44 are each driven to rotate in one direction in this state, the first slide plate 40 moves in the arrow X1 direction along the axis of the first screw shaft 43 as shown in FIG. At the same time, since the second slide plate 41 moves in the direction of the arrow X2 along the axis of the second screw shaft 45, the distance between the first slide plate 40 and the second slide plate 41 gradually decreases. When the rotation of the first motor 42 and the second motor 44 is further continued, as shown in FIG. 14, the first slide plate 40 and the second slide plate 41 move to a close position where the opposing surfaces abut each other, A large part including the central portion of the opening 33 is in the proximity state shielded by the first slide plate 40 and the second slide plate 41.

  Here, in this embodiment, the distance between the first slide plate 40 and the second slide plate 41 is intentionally changed, and the distance between the opposite ends on the free end (upper end) side of both slide plates 40 and 41 is changed. On the other hand, the distance between the opposing ends on the drive end (lower end) side is set in advance. For this reason, as shown in FIG. 15, when the corner portions on the free end side of the first slide plate 40 and the second slide plate 41 are in contact with each other, the corner portions on the drive end side are not yet in contact with each other, A triangular gap S <b> 2 is formed between the opposing surfaces of the first slide plate 40 and the second slide plate 41 with the drive end side as the base. When the rotation of the first motor 42 and the second motor 44 is continued from this state, the first slide plate 40 and the second slide plate 41 move so as to narrow the bottom of the gap S2 while keeping the free end side in contact, The rotations of the first motor 42 and the second motor 44 are stopped when the corners on the driving end side of the first slide plate 40 and the second slide plate 41 come into contact with each other. As a result, as shown in FIG. 16, the variable display device in which the opposing surfaces of the first slide plate 40 and the second slide plate 41 are in contact with each other from the free end side to the drive end side and face the opening 33. 14 display screens 14 a are reliably shielded by the first slide plate 40 and the second slide plate 41.

  As shown in FIGS. 17 and 18, the cable guide 31 is composed of a rear case 31a and a front case 31b. These cases 31a and 31b are fixed to the support base 22 in a joined and integrated state. ing. A circuit board 56 is housed inside the cable guide 31, and this circuit board 56 is connected to a control board (not shown) disposed on the back side of the game board 3. In addition, two fixed-side connectors 57 are mounted on the circuit board 56, and one end portions of the two flat cables 32 are connected to the fixed-side connector 57, and the other end portions of the two flat cables 32 are connected to each other. It is connected to a movable connector 58 attached to the outer periphery of the rotating plate 23 (see FIG. 3). Therefore, the control signals from the control board are applied to the electric components such as the motors 42 and 44 mounted on the rotating plate 23 rotating in both the forward and reverse directions and the LEDs in the slide plates 40 and 41 regardless of the rotation angle. Can be reliably transmitted via the flat cable 32. The two flat cables 32 are stacked in close contact except for the connection portion with the fixed connector 57. Since the appearance is not much different from one flat cable, the two flat cables 32 will be referred to below. It will be described as a single sheet.

  The inner wall surface facing the arcuate space S of the cable guide 31 has a curved surface shape, and a guide groove 59 is formed in the entire region from the upper end portion to the lower end portion of the inner wall surface. An outlet 60 is formed at a position slightly below the center of the guide groove 59, and the flat cable 32 connected to the fixed connector 57 inside the cable guide 31 is led downward from the outlet 60. After that, the direction is changed upward by the reversing part 32 a and connected to the movable connector 58 of the rotating plate 23. The guide groove 59 has a function of regulating the position of the flat cable 32 led out from the outlet 60 in the width direction, and the width dimension is set to be the same throughout the extending direction of the guide groove 59. The dimensions are partially changed in the extending direction of the guide groove 59. Specifically, the depth dimension of the guide groove 59 is gradually increased downward from the outlet 60, and the maximum depth d1 is set at the deepest position 59a above the lower end of the guide groove 59. . A portion from the outlet 60 to the upper end of the guide groove 59 is an extension guide 59b. The groove depth of the extension guide 59b is set to the same minimum depth d2 as the vicinity of the outlet 60. Yes.

  The relative position between the guide groove 59 and the reversing portion 32a of the flat cable 32 varies depending on the rotation angle of the rotating plate 23. When the rotating plate 23 is at the initial position, the reversing portion 32a is indicated by a solid line in FIG. The guide groove 59 is located in the vicinity of the deepest position 59a. In this case, the distance between the groove bottom surface of the guide groove 59 and the outer peripheral edge of the rotating plate 23 (the width dimension of the arcuate space S) becomes maximum at the deepest position 59a, so that the radius of curvature of the reversing portion 32a can be kept sufficiently large. This reduces the bending stress on the flat cable 32. When the rotating plate 23 rotates clockwise from the initial position, the reversing portion 32a is displaced to a position protruding from the lower end portion of the guide groove 59 as shown by a two-dot chain line in FIG. Since the portion of the flat cable 32 reaching the reversing portion 32a is regulated in the width direction by the guide groove 59, the reversing portion 32a protruding from the guide groove 59 does not collide with surrounding members and be damaged. On the contrary, when the rotating plate 23 rotates counterclockwise from the initial position, the reversing portion 32a moves away from the deepest position 59a of the guide groove 59 to the vicinity of the outlet 60 as shown by the broken line in FIG. However, in this case, the bending radius applied to the flat cable 32 is reduced because the radius of curvature of the reversing portion 32a is kept large by the presence of the outlet 60. Moreover, since the groove depth of the guide groove 59 is set so as to gradually increase from the outlet 60 toward the deepest position 59a, when the rotating plate 23 rotated to the end position in the counterclockwise direction is returned to the initial position, The reversing part 32a can be smoothly moved in the guide groove 59 and guided to the vicinity of the deepest position 59a.

  Next, the operation of the movable accessory device 13 configured as described above will be described mainly with reference to FIGS. 19 to 21 are operation explanatory views of the movable accessory device 13 as viewed from the front side of the game board 3, and both the slide plates 40 and 41 mounted on the rotating plate 23 and the both motors which are driving devices thereof. 42 and 44 and both screw shafts 43 and 45 are not shown.

  In the movable accessory device 13 according to the present embodiment example, the rotating plate 23 is in the initial position shown in FIG. 19 in a normal gaming state, and the opening 33 of the rotating plate 23 and the through hole 11 of the decorative case 12 are in this initial position. It is kept in a matching landscape shape. In this case, the first slide plate 40 and the second slide plate 41 are in the retracted positions hidden on the left and right sides of the opening 33, and the display screen 14 a of the variable display device 14 is exposed in the opening 33 through the through hole 22 a of the support base 22. is doing. In addition, the movable connector 58 attached to the outer peripheral portion of the rotating plate 23 faces the central portion of the cable guide 31 through the arc space S, and the reversing portion 32 a of the flat cable 32 connected to the movable connector 58. Is located in the vicinity of the deepest position 59 a of the guide groove 59 formed on the inner wall surface of the cable guide 31.

  When the drive motor 29 is rotationally driven in either of the forward and reverse directions in this state, the rotation of the drive motor 29 is transmitted from the reduction gear train 30 to the rotary plate 23 via the ring gear 36, so that the rotary plate 23 is moved from the initial position. Rotate clockwise. Then, when the rotating plate 23 is rotated clockwise by about 45 degrees from the initial position, as shown in FIG. 20, the flat portion 23c on the left side of the rotating plate 23 comes into contact with one stopper projection 27, and the drive motor is at that position. 29 is stopped to stop the rotation of the rotating plate 23. As a result, the opening 33 is inclined 45 degrees to the right with respect to the display screen 14 a, and a part of the decorative cover 38 disposed on the front surface of the rotating plate 23 is exposed from the through hole 11 of the decorative case 12. As the rotating plate 23 rotates, the movable connector 58 moves to the vicinity of the lower end of the cable guide 31, and the reversing portion 32 a of the flat cable 32 moves downward from the deepest position 59 a of the guide groove 59. Therefore, the portion of the flat cable 32 extending from the movable connector 58 to the lower end portion of the cable guide 31 becomes the reversing portion 32a having a large curvature radius.

  On the other hand, when the drive motor 29 is rotationally driven to the other side with the rotary plate 23 in the initial position, the rotary plate 23 rotates counterclockwise from the initial position. When the rotating plate 23 rotates counterclockwise from the initial position to about 45 degrees, as shown in FIG. 21, the flat portion 23c on the right side of the rotating plate 23 comes into contact with the other stopper projection 28 and is driven at that position. The driving of the motor 29 is stopped and the rotation of the rotating plate 23 is stopped. As a result, the opening 33 is inclined 45 degrees to the left with respect to the display screen 14 a, and a part of the decorative cover 38 is exposed from the through hole 11 of the decorative case 12. Further, as the rotating plate 23 rotates, the movable connector 58 moves to the vicinity of the upper end portion of the cable guide 31, and the reversing portion 32 a of the flat cable 32 follows the lead port 60 from the deepest position 59 a of the guide groove 59. Therefore, the flat cable 32 led out from the lead-out port 60 reaches the movable connector 58 through the arcuate space S facing the extension guide portion 59b. In this case, although the width dimension of the arc-shaped space S located on the side of the outlet 60 is narrower than that of the deepest position 59a, the presence of the outlet 60 formed by cutting out the groove bottom surface of the guide groove 59 is provided. Since the curvature radius of the reversing part 32a is kept large, the bending stress applied to the flat cable 32 is reduced. In addition, the rotating plate 23 is maintained at the initial position in most cases, and the frequency of the rotating plate 23 rotating to the position shown in FIG. Even if it becomes temporarily small, there is no possibility that the flat cable 32 may be damaged thereby.

  Further, when the rotary plate 23 is in an arbitrary rotational position including the initial position in this way, the slide plates 40 and 41 are opened and closed by performing the opening and closing operations of the first slide plate 40 and the second slide plate 41 described above. It is possible to realize an effect with an impact that associates the opening / closing direction of the image and the display content of the variable display device 14. For example, both slide plates 40 and 41 are reciprocated horizontally with respect to the display screen 14a while keeping the rotating plate 23 at the initial position during normal reach, or the rotating plate 23 is rotated clockwise or counterclockwise during super reach. If the slide plates 40, 41 are reciprocated in the oblique direction with respect to the display screen 14a during the rotation or at the rotation end position, the jackpot is made according to the opening / closing operation and the opening / closing direction of the slide plates 40, 41. It is possible to make the player suggest the degree of possibility.

  As described above, in the movable accessory device 13 according to this embodiment, the display screen 14a of the variable display device 14 can be visually observed on the rotary plate 23 that can rotate in a plane substantially parallel to the board surface of the game board 3. An opening 33 is provided, and a pair of slide plates 40 and 41 opposed to each other through the opening 33 are driven in the approach and separation directions along the axial direction of the screw shafts 43 and 45, respectively. In addition, since these screw shafts 43 and 45 are supported by the rotary plate 23 in a state where they are displaced in the front-rear direction on the same plane substantially orthogonal to the board surface of the game board 3, the pair of slide plates 40 and 41 are made large. The variable display device 14 having the display screen 14a can be arranged compactly. A pair of motors 42 and 44 for individually rotating and driving the pair of screw shafts 43 and 45 are mounted on the rotating plate 23 with a perpendicular L passing through the rotation center O of the rotating plate 23 as an axis of symmetry. Since the plates 40 and 41 and a pair of screw shafts 43 and 45 and a pair of motors 42 and 44 which are driving mechanisms thereof are arranged on the rotating plate 23 with a good weight balance, a rotation driving mechanism using the driving motor 29 as a driving source. When the rotary plate 23 is driven to rotate in either the forward or reverse direction, the load torque applied to the drive motor 29 is equalized in the forward rotation direction and the reverse rotation direction, and the pair of slide plates 40, 41 and their drive mechanisms, etc. The rotating plate 23 whose total weight is increased can be stably rotated.

  In addition, a pair of motors, a first motor 42 and a second motor 44, are arranged close to the rotating plate 23 with the opposite output shaft sides facing each other, and one screw shaft 43 is connected to the first motor 42. Since the other second screw shaft 45 extends from the output shaft toward the second motor 44 side, and the other second screw shaft 45 extends from the output shaft of the second motor 44 toward the first motor 42 side, The arrangement positions of the relatively heavy first motor 42 and second motor 44 come closer to the rotation center O of the rotating plate 23, and the rotating plate 23 can be rotated more stably. In addition, the rotary plate 23 is driven to rotate approximately the same amount in the forward and reverse directions with respect to the initial position, and the first motor 42 and the second motor 44 are directly below the center of the opening 33 at the initial position of the rotary plate 23. Therefore, the center of gravity of the entire rotating plate 23 is located directly below the center of the opening 33 at the initial position, and the rotating plate 23 can be smoothly rotated in both forward and reverse directions.

  In the above embodiment, the drive motor 29, the reduction gear train 30 and the ring gear 36 constitute a rotational drive mechanism, and the rotational plate 23 is rotated in both forward and reverse directions using the rotational drive mechanism having such a configuration. However, it is also possible to use a rotational drive mechanism having another configuration.
