  However, in the conventional movable decorative device described above, the first base to which the drive pulley, the driven pulley, the first upper support member and the first lower support member are attached is formed by bending a sheet metal, and this first base is formed. It is fixed to the game board base. As described above, since the whole of the first base including the lower part and the upper part is fixed to the game board base, there is a problem that the number of parts for fixing the first base increases and the structure becomes complicated. Moreover, since the 1st raising / lowering member only moves up and down along the guide rail fixed to the 1st base, there also exists a problem that the movement becomes monotonous and lacks in interest.

  The present invention has been made in order to address the above-described problems, and its object is to reduce the number of parts, simplify the structure, and change the movement of the decorative member. Is to provide. In the description of each constituent element of the present invention below, the reference numerals of corresponding portions of the embodiment are shown in parentheses in order to facilitate understanding of the present invention. The present invention should not be construed as being limited to the configurations of the corresponding portions indicated by the reference numerals of the forms.

  In order to achieve the above-mentioned object, the structural feature of the movable decoration device for a gaming machine according to the present invention is that the gaming machine (10) having a decorative member (A) for decorating the gaming surface (11) is movable. In the decoration device (20), a base portion (21) attached to the main body side of the gaming machine, a guide bar (31a, 31b), a base end bracket (32) provided at a base end of the guide bar, and a tip of the guide bar A guide member (31) including a distal end bracket (33) provided on the base portion and supported at the base portion so that the angle of the proximal end bracket can be changed, a drive pulley (37c) attached to the proximal end bracket, and the distal end bracket The idle pulley (38) attached to the slider, the slider (35) movable along the guide bar, and the drive pulley and the idle pulley while being engaged with the slider. The a drive belt (36a), in that a motor (26) to rotate the drive pulley.

  The movable decorative device for a gaming machine according to the present invention includes a base portion and a guide member supported by the base portion so that the angle can be changed. The guide member includes a guide bar and a guide bar. A proximal end bracket provided at the proximal end and a distal end bracket provided at the distal end of the guide bar are provided. Then, a drive belt is stretched over a drive pulley provided on the base end bracket and an idle pulley provided on the front end bracket, and a slider movable along the guide bar is engaged with the drive belt. For this reason, the slider can be moved along the guide bar by driving the motor and rotating the drive pulley. In addition, since the guide member can change the angle with respect to the base portion, two types of movements, that is, the movement of the guide member rotating and the movement of the slider moving along the guide bar can be generated. .

  As described above, in the movable decorative device for a gaming machine according to the present invention, the base end bracket of the guide member is supported by the base portion so that the angle can be changed. It can be rotated with respect to. For this reason, the guide member only needs to be supported by the base portion via the shaft portion or the like, and can have a simple structure, and a member for fixing becomes unnecessary. In addition, when the decorative member is attached to the slider, the decorative member can be rotated not only in a single direction but also in a rotating direction, which is interesting.

  Another structural feature of the movable decorative device for a gaming machine according to the present invention is that the drive gear (37b) provided integrally with the drive pulley and provided coaxially (37a) and the guide member by the central shaft (34a). A reduction gear (34) which is attached to the base portion in a state of being rotatably supported and transmits the driving force of the motor to the drive gear to rotate the guide member around the central axis, and the guide member is attached to the base portion. On the other hand, when the slider is between the initial position and the set tilt position in the rotation direction, the slider is engaged with the base portion, and the guide member is rotated via the drive gear by the drive of the motor. When it exceeds, the engagement between the slider and the base is released, and the drive belt is conveyed via the drive gear and drive pulley by driving the motor to move the slider. The movement switching mechanism (23, 35g, 35h) to be moved and the base end bracket are engaged with the base portion when the guide member exceeds the set inclination position, and the base end is set when the slider returns to the base end bracket side. A fixing switching mechanism (24, 29, 29e) for releasing the engagement between the bracket and the base portion is provided.

  According to the present invention, when the slider is engaged with the base portion and the guide member is in the initial position, even if the motor is driven to rotate in the direction in which the slider is moved toward the front end bracket, the slider cannot move. Is not transported. For this reason, the driving force of the motor is transmitted to the drive gear via the reduction gear, and the guide member is rotated from the initial position toward the set inclination position around the central axis of the reduction gear. When the inclination of the guide member exceeds the set inclination position, the base end bracket engages with the base portion and the guide member cannot be rotated any further. At the same time, since the engagement between the slider and the base portion is released, the driving force of the motor is transmitted to the drive belt via the reduction gear, the drive gear and the drive pulley, and the slider moves along the guide bar of the guide member to the end bracket. To move to the side.

  When the slider returns to the proximal bracket side by rotating the motor in the direction opposite to the aforementioned direction when the guide member is at the set inclination position and the slider is located on the distal bracket side. The slider cannot move any further. At the same time, the engagement between the base bracket and the base portion is released by the fixed switching mechanism, so that the driving force of the motor is transmitted to the drive gear via the reduction gear, and the guide member is moved from the set inclination position to the initial position. Rotate.

  Thus, according to the present invention, the operation in which the guide member rotates about the central axis of the reduction gear and the operation in which the slider moves along the guide bar of the guide member are continued. For this reason, the decorative member attached to the slider moves forward and backward as if drawing an L-shape, and the movement becomes more interesting. The initial position and the set tilt position in the rotation direction of the guide member are appropriately set. For example, the initial position is a vertical state, and the set tilt position is a state inclined by 45 degrees from the vertical state. It can be.

  Still another structural feature of the movable decorative device for a gaming machine according to the present invention is that the movement switching mechanism includes a narrow engagement recess (23a) and a wide release recess (23b) provided in the base portion. When the guide member provided on the slider is located between the initial position and the set inclination position, the guide member is slidably engaged with the edge of the engaging recess. This is because the engagement portion (35h) is located in the release recess and released from the movement switching portion when the position is exceeded.

  In this case, the movement switching unit is configured by a concave portion extending along the rotation direction of the guide member at a portion facing the guide member in the base portion. The engaging part can be moved from the inner side of the base part to the guide member side with respect to the release recess. Then, when the guide member exceeds the set inclination position, the engaging portion is positioned in the release recess. According to the present invention, the movement switching mechanism can be configured with a simple structure.

  Still another structural feature of the movable decorative device for a gaming machine according to the present invention is that the fixed switching mechanism includes a fixed switching portion including a wall portion provided in the base portion and provided with a fixing recess (24a), and a guide member. When the guide member is located between the initial position and the set tilt position, it can move along the wall of the fixed switching part, and when the guide member exceeds the set tilt position, it rotates and fixes to one side. A locking claw (29) that can be engaged with the concave portion and is rotated to the other side by pressing the slider and released from the fixing concave portion when the slider returns to the proximal bracket side, and a guide member It is constituted by a locking claw spring (29e) that is stretched over the locking claw and urges the locking claw to engage with the fixing recess.

  According to the present invention, the latching claw is urged by the latching claw spring so as to engage with the fixing recess, and the latching claw is moved when the guide member is between the initial position and the set inclination position. Along with being movable along the wall surface of the fixing switching portion, when the guide member exceeds the set inclination position, the fixing switching portion can be engaged with the fixing concave portion. For this reason, when the guide member exceeds the set inclination position, the locking claw reliably engages with the fixing recess, and the guide member is fixed to the base portion. Further, when the slider returns to the proximal bracket side, the engagement with the fixing recess is surely released by the pressing of the locking claw by the slider. According to the present invention, the fixed switching mechanism can be configured with a simple structure.

  Still another structural feature of the movable decorative device for a gaming machine according to the present invention is that the head shaft (41a) is attached to the slider, the head shaft being assembled to the slider, and the tip portion extending in the extension direction from the tip portion of the guide member. A pulley gear (39) having a pulley portion (39b) meshing with the drive belt and a direction changing gear (39c) having a rotation direction different from the rotation direction of the pulley portion, and a pulley gear direction changing gear. The bevel gear (43), which is attached to the head shaft in a state and rotates the head shaft in the direction around the axis by rotation of the pulley gear, restricts the head shaft from rotating in one direction around the axis, and the slider contacts the tip bracket. When it is in contact and can no longer move to the tip side, the bevel gear is allowed to rotate by driving the motor and the head shaft is rotated in one direction around the axis. And Nbane (42a), in that the rotation about the axis of the head axis and a rotation regulating portion for regulating to a predetermined angle (35j, 44).

  According to the present invention, when the motor is driven when the slider is positioned closer to the base end side than the front end bracket of the guide bar, the head shaft cannot rotate in one of the directions around the shaft due to the restriction of the torsion spring. The driving force is transmitted from the drive pulley to the driving belt, and moves the slider along the guide bar. At this time, the pulley gear is fixed to the slider without rotating. When the slider comes into contact with the tip bracket, the slider can no longer move to the tip side, and at the same time, the head shaft can rotate in one of the axial directions against the elasticity of the torsion spring. For this reason, the driving force of the motor is transmitted from the drive pulley to the drive belt, the pulley gear, and the bevel gear, and the head shaft rotates around the axis. When the rotation angle of the head shaft reaches a predetermined angle, the rotation is restricted by the rotation restricting unit.

  When the motor is rotated in the reverse direction, the head shaft first rotates in the direction opposite to the above-described rotation direction by the restoring force of the torsion spring. When the rotation angle reaches a predetermined angle, the rotation is restricted by the rotation restricting unit and the head shaft cannot be rotated. At the same time, since the pulley gear does not rotate and is fixed to the slider, the driving force of the motor is used to move the slider along the guide bar toward the proximal bracket.

  Thus, according to the present invention, the movement of the slider along the guide bar of the guide member and the movement of the head axis rotating in the direction around the axis are continued. For this reason, the decorative member attached to the slider rotates after moving to one side, or moves to the other after rotating, and the movement becomes more interesting. The rotation restricting portion can be configured, for example, by providing a stopper made of a projecting piece on the head shaft and providing an engaging convex portion with which the stopper abuts against a slider or a guide member. In this case, the head shaft can be rotated slightly less than one rotation.

Then, four screw insertion holes 46d are formed around the positioning hole 46c at intervals. The rotating body 46 is put on the guide member 31 and the inner cover 45 from above, and is assembled to the rotating body hub 41b with the circular convex portion 41d positioned in the positioning hole 46c. The screw insertion hole 46d is aligned with the screw hole 41c, and a screw (not shown) is passed through the screw insertion hole 46d and screwed into the screw hole 41c. In addition, the outer peripheral surface of the rotating body 46 is provided with a pattern or a decorative part is attached.

  Next, the operation when the movable decorative device 20 is operated will be described with reference to FIGS. 13 to 18 show a state in which the decorative member A is removed from the movable decorative device 20 in order to make the operating state of the moving mechanism 30 easy to understand. Further, the movable decorative device 20 shown in FIG. 1 shows a state before the operation, and in this case, as shown in FIG. 2 and FIG. The cover 45 is covered and is located at an upright initial position. Similarly, the guide member 31 is also upright as shown in FIGS. 13 and 14. The slider 35 is positioned at the lower ends of the guide bars 31 a and 31 b, and the engaging convex portion 35 h of the slider 35 is engaged with the engaging concave portion 23 a of the movement switching portion 23. The long piece of the lever 29b of the latching claw 29 is pressed downward by the slider 35, and one side surface of the protrusion 44b of the rotation stopper 44 is in contact with the regulating piece 35j.

  When the motor 26 operates from this state and the gear 26b rotates in the clockwise direction (counterclockwise when viewed from the front) in the state shown in FIG. 11, the reduction gear 34 rotates counterclockwise. As a result, a driving force that rotates in the clockwise direction is applied to the driving gear 37, but the slider 35 cannot engage with the base portion 21 and cannot be raised, so that the driving belt 36a is not conveyed and is kept stationary. For this reason, the drive gear 37 moves in the counterclockwise direction along the outer periphery of the small gear portion 34c of the reduction gear 34 without rotating in the direction around the axis, and the guide member 31 is shown in FIGS. As shown, it is inclined to the right side (left side in FIG. 11). In this case, the rotational speed of the gear 26b is reduced by the reduction gear 34, and the guide member 31 is slowly inclined. In this case, the guide member 31 moves against the elasticity of the return assist spring 28.

  When the guide member 31 exceeds the set inclination position (the state shown in FIG. 9) and the engaging convex portion 35 h is positioned in the release concave portion 23 b of the movement switching portion 23, the engagement between the slider 35 and the base portion 21 is established. The match is released. In this state, the slider 35 is movable obliquely upward. For this reason, the driving gear 37 starts to rotate clockwise about the central shaft 37a, and the slider 35 starts to rise by the driving force of the driving belt 36a. Then, when the slider 35 is raised, the locking claw 29 rotates about the shaft portion 29a in the counterclockwise direction in the state of FIG. 11 by the restoring force of the locking claw spring 29e, and the projection 29d becomes the fixed switching portion 24. Is engaged with the fixing recess 24a. As a result, the guide member 31 is fixed in the inclined state shown in FIGS. 15 and 16, and the driving gear 37 rotates in the clockwise direction while being stationary at the same position. In this case, the decorative member A is inclined as shown in FIG.

  While the slider 35 is raised, the head shaft 41a is restricted from rotating in the direction around the shaft by the elasticity of the torsion spring 42a and the restriction piece 35j. For this reason, the pulley gear 39 meshed with the bevel gear 43 cannot be rotated, and the slider 35 moves upward as if it were fixed to the drive belt 36a. Then, when the slider 35 reaches the upper end of the guide bars 31a and 31b (see FIGS. 17 and 18) and comes into contact with the end bracket 33, the slider 35 cannot be raised any further. In this case, the decorative member A is in an extended state in the window portion 15 while being inclined as shown in FIG. 6, and the inner cover 45 appears on the lower side of the rotating body 46 moved upward.

  When the slider 35 cannot be raised, the driving force of the driving belt 36a rotates the pulley gear 39 against the elasticity of the torsion spring 42a. At this time, both the upper and lower sides of the pulley gear 39 in the drive belt 36a are pressed against the opposite side of the drive belt 36a by the pair of tension applying pulleys 36b, so that the drive belt 36a is in an appropriate tension state to the pulley gear 39. Transmits driving force effectively. The rotation of the pulley gear 39 is transmitted to the head shaft 41a via the bevel gear 43, and rotates counterclockwise when the head portion 41 is viewed from above. In this case, the rotating body 46 rotates around the axis above the stationary inner cover 45 by the rotation of the head portion 41.

  When the head portion 41 rotates slightly less than one rotation and the other side surface of the protrusion 44b of the rotation stopper 44 comes into contact with the regulating piece 35j, the head portion 41 cannot rotate any more. At that timing, the motor 26 is rotated in the direction opposite to the rotation direction described above. At this time, since the restoring force of the torsion spring 42a is larger than the force for lowering the slider 35, first, the head portion 41 rotates in the clockwise direction as viewed from above. When one side surface of the protrusion 44b of the rotation stopper 44 comes into contact with the restricting piece 35j, the head portion 41 cannot be rotated any further, and the pulley gear 39 cannot be rotated.

  For this reason, the slider 35 descends as if it were fixed to the drive belt 36a. When the slider 35 comes into contact with the lower ends of the guide bars 31a and 31b, the slider 35 can no longer be lowered, and at the same time, the long piece of the lever 29b of the latching claw 29 is pressed downward, and the protrusion 29d. And the fixing recess 24a of the fixing switching unit 24 are disengaged. Further, the engaging convex portion 35 h enters the releasing concave portion 23 b of the movement switching portion 23. Further, since the guide member 31 is biased toward the initial position by the return assisting spring 28, the guide member 31 rotates and moves to the set inclination position, and the engagement convex portion 35h is engaged with the movement switching portion 23. Engages with the combined recess 23a. As a result, the drive gear 37 cannot rotate in the direction around the axis but moves in the clockwise direction along the outer periphery of the small gear portion 34 c of the reduction gear 34. Then, the guide member 31 rotates from the set tilt position toward the initial position and returns to the original state.

  In this way, by operating the motor 26, the decorative member A in the initial position is first inclined, and then the rotating body 46 of the decorative member A is moved obliquely upward, and the inner cover 45 is displayed on the lower side thereof. Then, only the rotating body 46 can be rotated in one direction. Further, after rotating the decorative member A in that state only the rotating body 46 in the other direction, the rotating body 46 is moved obliquely downward to accommodate the inner cover 45 therein, and the decorative member A is rotated. To return to the initial position. At that time, by changing the movement of the decorative member A, it is possible to change the emission by turning on or blinking the light emitting unit. Such an operation is executed during a game in a “reach” or “hit” state.

  As described above, in the movable decorative device 20 according to the present embodiment, the slider 35 can change the angle relative to the base portion 21 together with the guide member 31, and along the guide bars 31 a and 31 b of the guide member 31. Can move up and down. The head portion 41 attached to the slider 35 can rotate in the direction around the axis. In this case, since the guide member 31 is rotatably supported by the base portion 21 via the central shaft 34a of the reduction gear 34, a member or structure for supporting the distal end bracket 33 side of the guide member 31 is not necessary. As a result, the movable decoration device 20 can have a simple structure, and the number of members and the like for fixing can be reduced. In addition, the movement of the rotating body 46 attached to the head portion 41 is not only forward and backward in one direction, but also tilts and rotates, so that it is interesting.

  The movable decoration device for a gaming machine according to the present invention is not limited to the embodiment described above, and can be changed as appropriate. For example, in the above-described embodiment, the movable decoration device 20 is disposed at the lower part on the inner side of the window portion 15 formed on the game surface 11 with the decoration member A positioned upward, but the decoration member A is directed downward. The decorative member A may be positioned on the inner side upper portion of the window portion 15, or the decorative member A may be positioned on the left side or the right side and positioned on the right side or the left side of the inner side of the window portion 15. In the above-described embodiment, the guide member 31 is rotatably supported on the central shaft 34a of the reduction gear 34. However, the reduction gear 34 is omitted, and the gear 26b attached to the motor 26 is used for direct driving. You may make it mesh | engage with the drive gear 37b of the gearwheel 37. FIG. In this case, the guide member 31 is rotatably supported by the rotation shaft 26a of the motor 26.
