Description

  The present invention relates to a movable accessory device that suggests a result of electronic lottery to a player by a movable mode of a movable portion, and in particular, a rotating plate that rotates forward and backward in a variable display device and a support base that supports the rotating plate. The present invention relates to a flat cable routing structure used as an electrical connection means.

  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 are many models 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. A movable accessory device is known in which a circuit board on which an LED is mounted is fixed to an end portion of the movable body, and the circuit board is slid integrally with the movable body. (For example, refer to Patent Document 1). In this conventional example, both ends of a flat cable for supplying power to the LED are connected to the circuit board and the lamp control device. By providing this flat cable with a margin in the length direction, The sliding motion is absorbed by the displacement of the flat cable. Therefore, the movable body that reciprocates in the left-right direction or the vertical direction in front of the variable display device can be irradiated with the LED light regardless of the movement position, and the movement of the movable body and the LED light can be combined. Due to the effect, a highly interesting movable accessory device is realized.

  As another conventional example, a ring-shaped rotating plate having an opening is arranged around the variable display device, and the rotating plate is rotated by a predetermined angle in both forward and reverse directions by a rotation driving mechanism. There is known a movable accessory device that associates the display content of a variable display device that is visually observed through the rotating operation of a rotating plate (see, for example, Patent Document 2). In this conventional example, an opening through which the display screen of the variable display device can be seen is formed at the center of the rotating plate, and an annular ring gear is provided inside the outer peripheral edge of the rotating plate. The outer peripheral edge of the rotating plate is supported on a supporting base integral with the game board using a plurality of rollers, and a driving motor and a reduction gear train constituting a rotational driving mechanism are mounted on the supporting base. The reduction gear train is composed of a plurality of gears having different numbers of teeth, the first stage gear is fixed to the output shaft of the drive motor, and the last stage gear meshes with the ring gear of the rotating plate. Therefore, when the drive motor rotates forward or backward, the rotation is transmitted from the reduction gear train to the rotating plate via the ring gear, and accordingly, the rotating plate is either forward or reverse in front of the display screen of the variable display device. Since the image is rotated by a predetermined angle in the direction, it is possible to perform an effect in which the rotation operation of the rotating plate is associated with the display content of the display screen.

  By the way, as in the conventional example disclosed in Patent Document 1, when the movable body slide operation is absorbed using the flexibility of the flat cable having a margin in the length direction, the movable body slides. Since the flat cable that is displaced with the operation may interfere with many members present in the surrounding area, the flat cable is likely to be damaged such as disconnection. In this case, if the flat cable is connected to the circuit board and the lamp control device with the U-shape inverted, the inverted part of the flat cable can follow the moving direction of the circuit board. Undesirable interference with is greatly suppressed.

  However, as in the conventional example disclosed in Patent Document 2, in a movable accessory device in which a ring-shaped rotating plate supported by a support base rotates in both forward and reverse directions on the display screen, Since it is necessary to place the flat cable in a U-shaped inverted state in the space defined between the peripheral edge and the support base, if this space is narrow, the curvature of the inversion part becomes small and the flat cable As a result, a large bending stress that causes damage is applied. On the other hand, when the space between the rotating plate and the support base is wide, the bending portion applied to the flat cable can be reduced by increasing the curvature of the reversing portion, but the behavior of the reversing portion that moves following the rotation of the rotating plate can be reduced. Becomes unstable, and the effect of preventing interference between the flat cable and the surrounding members is significantly impaired.

  The present invention has been made in view of such a state of the art, and an object thereof is a movable accessory capable of preventing damage to a flat cable used as an electrical connection means between a rotating plate and a support base. To provide an apparatus.

  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 ring-shaped rotating plate provided with an opening through which the display screen of the variable display device can be visually observed, a support base that rotatably supports the rotating plate, and a surface substantially parallel to the surface of the game board A rotation drive mechanism that rotates the first base position in both forward and reverse directions by a predetermined angle, and a belt-like flat cable that electrically connects the support base and the rotary plate, and the flat cable is connected to the outside of the rotary plate. Arranged in a state having a U-shaped reversal portion in an arc-shaped space defined between a peripheral edge and the inner wall surface of the support base, the outlet port and the outlet port led to the inner wall surface of the support base Flat cave And a guide groove for regulating the position in the width direction, the groove depth of the guide groove is set to a maximum depth at a position away from the outlet, and the reversing portion of the flat cable is at an initial position of the rotating plate. It was set to be located in the vicinity of the deepest portion of the guide groove.

  In the movable accessory device configured as described above, the flat cable is disposed in the arc-shaped space between the outer peripheral edge of the rotating plate and the inner wall surface of the support base in a state having a U-shaped reversing portion. Is in the initial position, the portion of the flat cable that is led out from the outlet of the support base and reaches the reversing part is regulated in the width direction by the guide groove, and the reversing part is located near the deepest part of the guide groove. Therefore, the bending stress applied to the inversion part of the flat cable can be reduced. In addition, when the rotating plate rotates in either the forward or reverse direction from the initial position, the reversing part of the flat cable follows the rotating direction of the rotating plate and moves away from the deepest part of the guide groove. Since the flat cable in the part reaching the reversing part is regulated in the width direction by the guide groove, the reversing part can smoothly follow the rotation direction of the rotating plate, and the flat cable interferes with surrounding members. It can be prevented from being damaged.

  In the above configuration, when the groove depth of the guide groove is gradually increased from the outlet to the deepest part, the reversing portion of the flat cable can be smoothly moved in the extending direction of the guide groove as the rotating plate rotates. This is preferable.

  In the movable accessory device of the present invention, the flat cable is disposed in an arcuate space between the outer peripheral edge of the rotating plate and the inner wall surface of the support base, with the U-shaped reversing portion, and the rotating plate is at the initial position. In this case, the portion of the flat cable that is led out from the outlet of the support base and reaches the reversing portion is regulated in the width direction by the guide groove, and the reversing portion is located near the deepest portion of the guide groove. The bending stress applied to the reversal part of the flat cable can be reduced. In addition, when the rotating plate rotates in either the forward or reverse direction from the initial position, the reversing part of the flat cable follows the rotating direction of the rotating plate and moves away from the deepest part of the guide groove. Since the flat cable in the part reaching the reversing part is regulated in the width direction by the guide groove, the reversing part can smoothly follow the rotation direction of the rotating plate, and the flat cable interferes with surrounding members. It can be prevented from being damaged.

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.

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 arc space S is formed between the outer peripheral edge of the ring-shaped rotating plate 23 and the inner wall surface of the cable guide 31 provided on the support base 22. In addition, the flat cable 32 having both ends connected to the fixed connector 57 and the movable connector 58 is disposed in the arcuate space S in a state having a U-shaped reversing portion 32a. When in the position, the position of the flat cable 32 extending from the outlet 60 to the reversing portion 32a is restricted in the width direction by the guide groove 59 formed on the inner wall surface of the cable guide 31, and the reversing portion 32a is the guide groove. 59 is set so as to be located in the vicinity of the deepest position 59a, so that the radius of curvature of the reversing portion 32a is sufficiently large at the initial position of the rotating plate 23 occupying most of the game. It kept, thereby reducing the bending stress applied to the flat cable 32.

  Further, when the rotating plate 23 is rotated in a direction in which the movable connector 58 approaches the deepest position 59a, the reversing portion 32a of the flat cable 32 protrudes from the lower end portion of the guide groove 59 and leaves the deepest position 59a. The portion of the flat cable 32 that is led out from the lead-out port 60 and reaches the reversing part 32 a is regulated in the width direction by the guide groove 59, so that the reversing part 32 a can smoothly follow the rotation direction of the rotating plate 23. It is possible to prevent the flat cable 32 from being damaged by interfering with surrounding members.

  On the contrary, when the rotary plate 23 is rotated in a direction in which the movable connector 58 moves away from the deepest position 59a, the reversing portion 32a of the flat cable 32 moves from the deepest position 59a to the vicinity of the outlet 60, but the guide groove 59 Since the curvature radius of the inversion part 32a is kept large by the outlet 60 formed by cutting out the groove bottom surface, the bending stress applied to the flat cable 32 can be reduced also in this case. Moreover, since the groove depth of the guide groove 59 is formed so as to gradually increase from the outlet 60 toward the deepest position 59a, when the rotary plate 23 is rotated and returned from the above state to the initial position, the reversing portion 32a Can be smoothly moved in the guide groove 59 and guided to the vicinity of the deepest position 59a.

  In the above embodiment, the cable guide 31 is configured by the rear case 31a and the front case 31b, and such a cable guide 31 is retrofitted to the support base 22. However, the configuration of the cable guide 31 is not limited to this. For example, the guide groove 59 is formed on the inner wall surface of the cable guide 31 formed integrally with the rear case 31a and the front case 31b, or the guide groove 59 is formed on the inner wall surface of the cable guide 31 formed integrally with the support base 22. It is also possible to form
