  The movable decorative device described above includes a motor that moves the lifting body up and down via a lifting mechanism and a motor that moves the stopper for preventing the lifting body from falling to the left and right. For this reason, in the above-described movable decoration device, control for synchronizing both motors is required, resulting in a complicated structure and an increase in cost. Furthermore, a space for installing the control board is also required, and there is a problem that the movable decoration device is enlarged.

  The present invention has been made to address the above-described problems, and an object of the present invention is to provide a movable decoration device for a gaming machine that has a simple structure and is inexpensive. 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 movable decoration device for a gaming machine (A) provided with decorative members (B1, B2) for decorating the game surface. ), A base portion (11) provided with a support shaft (11b), a drive force transmission gear (13) rotatably supported by the support shaft, and a drive motor (12) for rotating the drive force transmission gear. The rotating drum (14) that is rotatably supported by the support shaft facing the driving force transmission gear, the base end is connected to the rotating drum and the tip is connected to the decorative member, and the rotating drum is rotated by the rotation of the rotating drum. A flexible linear body (23) that moves up and down the decorative member by being wound around or sent out from the rotating drum, and the driving force transmission gear as the rotating drum when the driving force transmission gear rotates in one direction. Engage the rotating drum in one direction The ascending engagement means (13f, 14i) for rotating and raising the decorative member, and when the linear member is wound around the rotating drum and the decorative member is raised, the decorative member is engaged with the rotating drum and raised. The winding holding engagement means (14f, 15, 17) to be maintained at the same time, and the winding holding engagement means and the rotating drum are disengaged when the driving force transmission gear rotates in the other direction. There is provided an engagement release means (13g) for rotating the rotating drum to the other side by the weight of the member and lowering the decorative member.

  In the movable decorative device for a gaming machine according to the present invention, when the driving force transmission gear rotates in one direction by the operation of the driving motor, the rotating drum is engaged with the driving force transmission gear by the ascending engagement means, and the rotating drum Is rotated in one direction to raise the decorative member. Then, when the linear body is wound around the rotating drum and the decorative member is raised to the uppermost position, the rotating drum is stopped by the engaging means at the time of hoisting and the decorative member is maintained at the uppermost position. The Further, from this state, when the driving force transmission gear rotates in the other direction by the operation of the driving motor, the engagement releasing means releases the engaged state by the winding holding engagement means. As a result, the decorative member rapidly descends while rotating the rotating drum in the other direction by its own weight.

  When the driving force transmission gear rotates in the other direction, the engagement state between the driving force transmission gear and the rotary drum by the ascending engagement means is released. For this reason, the rotating drum independently rotates in the other direction regardless of the driving force transmission gear. In this case, the descent of the decorative member occurs at a predetermined timing, for example, when representing a gaming state such as reach, thereby increasing the fun of the game. Further, in the movable decoration device for a gaming machine according to the present invention, when the driving motor is rotated and the driving force transmission gear is rotated in one direction, the decoration member rises, and the driving motor is reversed to transmit the driving force. When the gear is rotated in the other direction, the decorative member rapidly descends, so only one drive motor is required. This eliminates the need for complicated controls and devices and reduces costs.

  Further, another structural feature of the movable decorative device for a gaming machine according to the present invention is that a protrusion is formed on each of the opposing surfaces of the rotating drum and the driving force transmission gear, and the both-protrusion engaging means is ascending. It is in having constituted. According to the present invention, when the driving force transmission gear rotates in one direction due to the operation of the driving motor, the protrusion of the driving force transmission gear engages with the protrusion of the rotating drum and follows the rotation of the driving force transmission gear. The rotating drum will also rotate in one direction. And by this rotation of a rotating drum, a linear body is wound up by a rotating drum and a decoration member raises. In this way, the rotating drum can be rotated by following the rotation of the driving force transmission gear with a simple configuration in which the protrusions are respectively formed on the rotating drum and the driving force transmission gear. When the driving force transmission gear rotates in the other direction, the protrusion of the driving force transmission gear moves away from the protrusion of the rotating drum.

  In addition, still another structural feature of the movable decorative device for a gaming machine according to the present invention is that a stop recess (14f) is formed on the outer peripheral portion of the rotary drum, and the engaging means at the time of hoisting is used as the stop recess And a stopper (15) having an engagement piece (15b) that can be engaged with the stop recess, and an urging means (17) for urging the engagement piece to the outer peripheral portion of the rotating drum. is there.

  According to the present invention, since the engaging piece is urged to the outer peripheral portion of the rotating drum by the urging means, the rotating drum rotates in one direction following the driving force transmission gear by the operation of the driving motor. When the combined piece reaches the stop recess, the engagement piece and the stop recess engage. In this case, when the rotating drum rotates in one direction to wind up the linear body and raise the decorative member to the uppermost position, the recess for stopping reaches the position of the engaging piece. As a result, the decoration member is maintained in a state where it is raised to the uppermost position during normal times when it is not necessary to represent a gaming state such as reach.

  Further, in a state where the decorative member is raised to the uppermost position, it is preferable that the decorative member is hidden from the surface of the gaming machine. According to this, the fun when the decorative member suddenly descends further increases. Further, when the engaging piece engages with the stop recess, the rotating drum cannot be rotated any further. Therefore, the rotating drum does not rotate until a maximum of one rotation from the state where the engaging piece engages with the stop recess. Can rotate at the same angle in one direction or the other. For this reason, the raising / lowering distance of a decoration member becomes fixed.

  Still another structural feature of the movable decorative device for a gaming machine according to the present invention is that the disengagement means comprises an disengagement piece made up of a protrusion provided on the drive force transmission gear, and the drive force When the transmission gear rotates in the other direction, the disengagement piece presses the stopper against the biasing means so that the engagement piece moves away from the outer peripheral portion of the rotating drum.

  According to the present invention, the driving force transmission gear rotates in the other direction in which the protrusions of the driving force transmission gear and the protrusions of the rotating drum that constitute the engaging means at the time of lifting are separated, so that the driving force transmission gear rotates independently. The rotating drum is kept stationary. When the engagement release piece of the driving force transmission gear comes into contact with the stopper and presses the stopper so that the engagement piece moves away from the outer peripheral portion of the rotating drum, the engagement between the stop recess and the engagement piece is established. The rotary drum is released and is pulled by the decorative member via the linear body and rotates in the other direction. The decorative member is rapidly lowered by the rotation of the rotating drum in the other direction.

  In addition, another structural feature of the movable decorative device for a gaming machine according to the present invention is that the driving force transmission gear is disposed so as to face the base portion, and the rotation restriction is provided on the surface of the base portion facing the driving force transmission gear. The protrusion (11c) is provided, and the driving force transmission gear is provided with a rotation range restricting protrusion (13d) that can contact the rotation restricting protrusion, thereby restricting the rotation range of the driving force transmission gear within one rotation. It is in. According to the present invention, the driving force transmission gear is configured such that, at the maximum, one side of the rotation range restricting protrusion is in contact with the other side of the rotation restricting protrusion, and the other side of the rotation range restricting protrusion is on one side of the rotation restricting protrusion. It can be rotated at the same angle in one direction or in the other direction within one rotation until contact.

  Further, another structural feature of the movable decorative device for a gaming machine according to the present invention is that a rotating drum is provided along the circumference of the outer peripheral portion, and a groove portion around which a linear body can be wound, and the rotary drum is rotated from the groove portion. That is, it is constituted by a disc body provided with a fixing hole (14k) extending to the inner side of the drum and fixing the base end of the linear body at the distal end. According to the present invention, when the rotating drum rotates, the linear body can be reliably wound around the outer peripheral portion of the rotating drum. Further, since the base end of the linear body is fixed to the fixing hole extending from the groove portion to the inside of the rotary drum, the base end of the linear body becomes an obstacle when the linear body is wound around the rotary drum. Disappears. The rotating drum can be configured by assembling a pair of disk bodies. In this case, the formation of the fixing hole is facilitated.

  In addition, still another structural feature of the movable decorative device for a gaming machine according to the present invention is that the upper part of the extendable slide rails (21, 22) is fixed to the base part, and the lower part of the slide rail is used as a decorative member. By connecting and sliding the slide rail to follow the raising and lowering of the decorative member, the track when the decorative member moves up and down is made constant. According to the present invention, the decorative member moves in a certain direction along the slide rail without swinging left and right, so that the decorative member moves stably.

  The driving force transmission gear 13 is configured as shown in FIGS. 7 and 8, and a cylindrical shaft hole portion 13a into which the support shaft 11b can be inserted is formed at the center, and the gear portion with which the driving gear 12c can mesh. 13b consists of a disk body formed on the outer periphery. A ring-shaped protrusion 13c having a diameter smaller than that of the protrusion 11a of the base portion 11 is formed on the outer peripheral side of the shaft hole portion 13a on the back surface of the driving force transmission gear 13, and the inner peripheral side of the protrusion 13c. A rotation range restricting protrusion 13d made of a V-shaped protrusion having an outer peripheral side widened is formed. Further, a ring-shaped protrusion 13e having the same diameter as the protrusion 13c is formed on the outer peripheral side of the shaft hole portion 13a on the surface of the driving force transmission gear 13, and the protrusion is formed on the inner peripheral side of the protrusion 13e. A gear-side engaging portion 13f made of an I-shaped protrusion extending from the inner peripheral surface of the strip 13e toward the shaft hole portion 13a is formed.

  Further, on the outer peripheral side of the surface of the driving force transmission gear 13, an engagement releasing piece 13g made of a rectangular protrusion is formed. The driving force transmission gear 13 configured as described above is assembled to the base portion 11 in a state where the support shaft 11b is inserted into the shaft hole portion 13a and the gear portion 13b is engaged with the driving gear 12c of the driving motor 12. ing. The driving force transmission gear 13 rotates in a reversible manner in one direction (clockwise direction) or the other direction (counterclockwise direction) by the operation of the driving motor 12. At this time, the driving force transmission gear 13 is configured such that the other side portion of the rotation range restricting projection 13d is rotated from the state where one side portion of the rotation range restricting projection 13d is in contact with the rotation restricting projection 11c. It can rotate until it touches.

  That is, the right portion of the rotation range restricting protrusion 13d in the state shown in FIG. 7 (the left portion when viewed from the front) restricts the clockwise rotation of the driving force transmission gear 13 when viewed from the front. The left portion of the rotation range restricting protrusion 13d (which is the right portion when viewed from the front) restricts the driving force transmission gear 13 from rotating counterclockwise when viewed from the front. As a result, the driving force transmission gear 13 can be rotated slightly less than one rotation around the support shaft 11b. In addition, the protrusion 13c is located in the inner peripheral side of the protrusion 11a. Further, the number of teeth of the gear portion 13b is larger than the number of teeth of the drive gear 12c, and the rotational speed of the drive motor 12 is decelerated and transmitted to the drive force transmission gear 13.

  As shown in FIG. 9, the rotary drum 14 is configured by combining a rear surface portion 14 </ b> A and a front surface portion 14 </ b> B both formed in a disk shape. A cylindrical bearing portion 14c extending in the front-rear direction is formed at the center of the rear surface portion 14A, and a fitting hole 14d into which the front portion of the bearing portion 14c can be fitted is formed at the center of the front surface portion 14B. The rear surface portion 14A and the front surface portion 14B are assembled with each other by fitting the front portion of the bearing portion 14c into the fitting hole 14d. Further, the support shaft 11b can be inserted into the bearing portion 14c, and the rotary drum 14 has the support shaft 11b inserted through the bearing portion 14c and the back surface thereof facing the surface of the driving force transmission gear 13 to the base portion 11. It is assembled.

  As shown in FIG. 10, a substantially ring-shaped protrusion 14e having a diameter larger than that of the protrusion 13e is formed on the outer peripheral side of the rear surface of the rear surface part 14A, and a part of the protrusion 14e is a rear surface part. Projecting toward the center of 14A, the outer peripheral side is recessed. The recessed part 14f for a stop which concerns on this invention is comprised by the part in which this outer peripheral side became depressed. Further, four screw holes 14g penetrating the rear surface portion 14A in the front-rear direction are formed at a portion along the protrusion 14e in the rear surface portion 14A, and the screw holes 14g are formed in the front surface portion 14B. Four screw insertion holes 14h are formed at the same interval.

  With the rear surface portion 14A and the front surface portion 14B assembled, a screw (not shown) is passed through the screw insertion hole 14h, and the screw is screwed into the screw hole 14g, so that the rear surface portion 14A and the front surface portion 14B are mutually connected.

  When the driving force transmission gear 13 rotates in the clockwise direction by the operation of the driving motor 12, the drum side engaging portion 14i abuts on the gear side engaging portion 13f and is pushed by the gear side engaging portion 13f. The rotating drum 14 is rotated. At this time, the engaging portion of the drum side engaging portion 14i contacts the gear side engaging portion 13f. The gear side engaging portion 13f and the drum side engaging portion 14i constitute the ascending engagement means according to the present invention. In this case, the protrusion 14e is located on the outer peripheral side of the protrusion 13e. Further, the gear side engaging portion 13f and the drum side engaging portion 14i are in contact with each other when the rotation range restricting protrusion 13d is located on the left side in the vicinity of the rotation restricting protrusion 11c. For this reason, when the driving force transmission gear 13 rotates in the clockwise direction, the rotating drum 14 rotates in the clockwise direction together with the driving force transmission gear 13, and the rotation range restricting projection 13d is substantially halfway away from the rotation restricting projection 11c. After rotating, it approaches the right side of the rotation restricting protrusion 11c.

  A guide wall 14j made of a substantially ring-shaped protrusion is formed on the outer peripheral side of the front surface of the rear surface portion 14A. A predetermined portion of the guide wall 14j is cut out, and a linear groove-shaped fixing hole 14k extends from the cut-out portion toward the inner side of the rear surface portion 14A. The fixing hole 14k is located on the inner side of the rotating drum 14 in the clockwise direction when the rotating drum 14 rotates in the clockwise direction, and on the inner side when the rotating drum 14 rotates in the counterclockwise direction. It inclines so that it may be located behind a rotation direction rather than the exterior side.

  By providing the guide wall 14j, when the rear surface portion 14A and the front surface portion 14B are assembled, a gap is generated on the outer peripheral side of the rear surface portion 14A and the front surface portion 14B. A groove portion according to the present invention is configured by the opposing surface of the outer peripheral side portion of the rear surface portion 14A and the front surface portion 14B and the outer peripheral surface of the guide wall 14j. The proximal end portion of the wire 23 is fixed to a circular portion at the back end of the fixing hole 14k, and the wire 23 is assembled to the rotary drum 14 in a state where it can be wound around the groove portion. For this reason, when the rotating drum 14 rotates in the clockwise direction, the wire 23 is wound around the groove, and when the rotating drum 14 rotates in the counterclockwise direction, the wire 23 is fed out of the groove.

  As shown in FIG. 11, the stopper 15 includes an elongated plate-like main body 15a extending diagonally from the lower left to the upper right, an engagement piece 15b protruding from the upper end of the main body 15a to the upper left, and a base end of the main body 15a. A lever-like member comprising a release wall portion 15c formed on the upper side of the body, a spring locking piece 15d extending to the left from the base end portion of the main body 15a, and a shutter portion 15e provided at the front end of the main body 15a.

The engagement piece 15b is formed of a rectangular protrusion that can engage with the stop recess 14f of the rotary drum 14, and the release wall 15c has an edge extending substantially vertically and an edge extending substantially horizontally. The provided front view is constituted by substantially triangular protrusions.

  Further, the spring locking piece 15d is formed in a tapered plate shape, and a concave portion for locking the upper portion of the spring 17 is provided at the upper end of the tip. The shutter portion 15e is composed of a rectangular small protrusion formed thinner than other portions constituting the stopper 15. The stopper 15 is assembled to the base portion 11 so that the screw hole portion 11g is inserted into the support hole 15f and is rotatable about the screw hole portion 11g. In this case, the engaging piece 15 b and a part of the stopper 15 on the engaging piece 15 b side are located on the outer peripheral side portion between the driving force transmission gear 13 and the rotating drum 14. Note that a screw 15g (see FIG. 12) inserted from the surface side of the stopper 15 is screwed into the screw hole 11g, and the stopper 15 cannot be detached from the screw hole 11g by the head of the screw 15g. Yes.

  The spring 17 includes a spring portion 17a, a substantially ring-shaped engagement portion 17b provided at the upper end of the spring portion 17a, and a substantially ring-shaped engagement portion 17c provided at the lower end of the spring portion 17a. Has been. The spring 17 engages the engaging portion 17b with the concave portion of the spring locking piece 15d, engages the engaging portion 17c with the locking portion 11j of the base portion 11, and moves the spring locking piece 15d downward. By pulling, the engaging piece 15b is pressed against the outer peripheral surface of the protrusion 14e of the rotating drum 14.

  The driving force transmission gear 13 is rotated in the clockwise direction by the operation of the driving motor 12, and the rotating drum 14 is rotated with the rotation of the driving force transmission gear 13, so that the stop recess 14 f is an engagement piece of the stopper 15. When reaching 15b, the engaging piece 15b enters the stop recess 14f by the biasing force of the spring 17. In this state, when the drive force transmission gear 13 rotates counterclockwise by the operation of the drive motor 12 and the engagement release piece 13g reaches the position of the stopper 15, the release surface of the engagement release piece 13g. (The upper right surface of the disengagement piece 13g shown in FIG. 8) abuts on an edge portion of the release wall portion 15c that extends substantially vertically.

  Further, when the driving force transmission gear 13 rotates counterclockwise, the disengagement piece 13g rotates the stopper 15 in the direction in which the engagement piece 15b moves away from the rotating drum 14 against the elasticity of the spring 17. Thus, the engagement between the engagement piece 15b and the stop recess 14f is released. As a result, the rotating drum 14 becomes rotatable, and rotates counterclockwise by the weight of the decorative members B1 and B2. In this case, the rotating drum 14 is slightly rotated, that is, from the state where the drum side engaging portion 14i and the gear side engaging portion 13f are separated from each other by one turn of the rotating drum 14, the drum side engaging portion 14i and the gear side engaging portion. Rotate until the joint portion 13f comes into contact. The stopping recess 14f, the stopper 15, and the spring 17 constitute the winding holding engagement means according to the present invention, and the engagement releasing piece 13g constitutes the engagement releasing means according to the present invention.
