Description

The present invention relates to an effect power transmission mechanism for a game machine for raising and lowering an effect movable part provided on a game board of the game machine, and a game machine including the same.

  Game machines such as pachinko are equipped with an image display device, an illumination device, a moving part for production, etc., to diversify the contents of the game, and the movement for production is triggered by winnings during the game and other situation changes The production effect is enhanced by moving the parts in a predetermined direction.

  For example, Patent Document 1 discloses a pachinko gaming machine including a moving part for presentation that moves up and down in accordance with the game characteristics of a game. This production movable part can be moved up and down by expansion and contraction of a pair of suspension members provided in the center of the upper side of the decorative frame surrounding the periphery of the image display device disposed in the center of the game board. It is configured.

  The suspension member is configured to be able to bend and stretch by attaching the suspension lower member to the lower portion of the suspension upper member so as to be rotatable. The lower end of one hanging lower member is pivotally attached to one end of the movable part for production, and the lower end of the other hanging lower member is pivotable to the other end of the movable movable part. The effect moving parts are supported by a pair of suspension members. Driving means for moving the hanging movable member up and down by rotating the hanging member is provided above the pair of hanging upper members. The drive means includes a motor, a drive gear attached to the rotation shaft of the motor, a driven gear meshing with the drive gear, an engagement pin provided on the driven gear, and a pin provided on the suspension upper member. And a long hole.

  When the motor of the driving means is driven, the driven gear is rotated to one side, and the engaging pin is moved in the elongated hole, and one suspended upper member is rotated in the vertical direction. The suspended upper member also rotates in the vertical direction. And according to rotation of these pair of suspension upper members, the suspension lower member corresponding to these can also be rotated up and down, and the production movable parts can be raised and lowered.

Japanese Patent Laying-Open No. 2006-240629 (paragraphs 0020 to 0024, FIGS. 5 and 6)

  This stage moving part moves up and down by rotating the motor forward and backward, but if the motor keeps rotating forward or backward depending on the contents of the game or if it rotates instantaneously in the opposite direction, the motor temperature will rise excessively. This may reduce the motor life.

  Therefore, if the power transmission mechanism of the lifting device is configured so that the reverse rotation of the motor is restricted when the moving parts for production are lowered and the drive gear is separated from the driven gear accordingly, the drive gear is driven during the reverse rotation of the motor. By performing the reverse rotation of the motor just by moving it away from the gear, the moving parts for presentation can be lowered by its own weight. Therefore, the power consumption of the motor during reverse rotation of the motor can be reduced, and a reduction in motor life can be suppressed.

  The present invention responds to such a demand, and it is an object of the present invention to provide a gaming machine presentation power transmission mechanism capable of restricting reverse rotation of the motor when the stage moving parts are lowered, and a gaming machine including the same. And

  In order to solve such a problem, the present invention is an effect power transmission mechanism for an amusement machine that transmits the power of a motor to an effect movable part provided in a gaming machine and moves the effect movable part, An internal gear that is attached to the rotation shaft of the motor and rotates with the rotation of the rotation shaft; a side member that is rotatably supported and has an internal gear disposed on one side; and an internal gear between the internal gear and the side member. The claw member is disposed on the inner side of the inner gear and is rotatably supported coaxially with the internal gear, and has a claw member integrally coupled with the side member, and the claw member is rotatably supported on the inner side of the internal gear. A rotating part, an arm part having one end connected to the rotating part and the other end extending along the inner periphery of the internal gear and supported to be elastically deformable in the radial direction of the internal gear, and the other end of the arm part A claw portion that is provided at the side tip and contacts the tooth portion of the internal gear. Contact with the toothed portion of the internal gear in an energized state, permitting movement of the toothed portion of the internal gear during rotation of one side of the internal gear, allowing rotation of the internal gear, and rotating during reverse rotation of the internal gear. The reverse rotation of the internal gear is restricted by striking the portion (claim 1).

  The internal gear may be one that is directly attached to the rotating shaft of the motor, one that is formed integrally with another gear attached to the rotating shaft of the motor, or one that is disposed inside the side member. The side member may be rotatably provided on the rotation shaft of the motor, or may be rotatably provided on the rotation shaft that is coaxial with the rotation shaft of the motor and provided on the internal gear.

  Since the claw member is disposed inside the internal gear and is rotatably supported coaxially with the internal gear, it is possible to provide a production power transmission mechanism that is small and can regulate the reverse rotation of the internal gear. The installation space for the production power transmission mechanism in the plane can be reduced.

  The arm portion of the claw member is a cantilever supporting member having one end connected to the rotating portion and the other end extending along the inner periphery of the internal gear. The arm portion comes into contact with the tooth portion formed on the inner side of the internal gear at the tip end side in an elastically deformed state. For this reason, the nail | claw part provided in the front-end | tip part of an arm part always contacts in the state which biased the tooth | gear part of the internal gear.

  The claw portion has, for example, a sawtooth triangular protrusion. The triangular protrusion has a small inclined portion with a small inclination and a large inclined portion with a large inclination with respect to the inner periphery of the internal gear. When the claw portion is configured in this way, when the internal gear rotates so that the tooth portion of the internal gear advances from the bottom side to the top side of the small inclined portion, the arm portion is elastically deformed to the inside of the internal gear, so Movement of the gear teeth is allowed. On the other hand, when the tooth portion of the internal gear advances in the direction approaching the large inclined portion side, the tooth portion hits the large inclined portion and the reverse rotation of the internal gear is restricted.

  A plurality of claw members are provided at predetermined intervals in the circumferential direction of the rotating part with respect to the rotating part (claim 2). The claw members may be provided at equal intervals in the circumferential direction of the rotating part. Since the claw member includes a plurality of claw parts, each claw part can abut against the tooth part of the internal gear. For this reason, while being able to increase the rotation control intensity | strength of an internal gear, the durable intensity | strength of a nail | claw member can be improved.

  The invention of the present application is a gaming machine comprising the power transmission mechanism for production described in at least one of claims 1 and 2 (claim 3). A gaming machine provided with an effect power transmission mechanism includes a pachinko gaming machine, a slot machine, and the like.

  According to the power transmission mechanism for production of the gaming machine and the gaming machine equipped with the same according to the present invention, the internal gear attached to the rotating shaft of the motor and rotating along with the rotation of the rotating shaft, and rotatably supported on one side. A side member on which the internal gear is arranged, and between the internal gear and the side member, arranged inside the internal gear, rotatably supported coaxially with the internal gear, and integrally coupled to the side member By having the claw member formed, the tooth portion of the internal gear abuts on the claw member when the internal gear rotates in the reverse direction, and the reverse rotation of the internal gear can be restricted.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 3 (front view) shows a configuration example of the effect power transmission mechanism of the game machine 1 that can move up and down the effect movable part 126 provided in the upper center of the game board 101. The gaming machine 1 will be described by taking a pachinko machine as an example, but the gaming machine is not limited to a pachinko machine, and may be a slot machine or the like.

  First, the entire gaming machine will be described. An operation handle (not shown) having a launching unit is disposed below the gaming board 101 of the gaming machine 1, and a game ball launched by driving the launching unit rises between the rails 102 a and 102 b and moves upward from the gaming board 101. After reaching the position, the game area 103 is dropped. In the game area 103, in addition to a plurality of nails 104 for dropping the game ball in an unspecified direction, a windmill and a entrance for changing the fall direction of the game ball are arranged.

  A symbol display unit 105 using a liquid crystal display (LCD), for example, is disposed in the central portion of the game area 103. A first start port 106 capable of receiving a game ball is disposed below the central portion of the symbol display unit 105 in the left-right direction. Below the symbol display unit 105 on the left side, there is arranged a normal winning port 107 for acquiring a predetermined number (for example, ten) of winning a prize ball when a game ball enters.

  A second start port 110 having a pair of movable pieces 110a is disposed below the right side of the symbol display unit 105. The second starting port 110 makes it difficult to receive a game ball when the pair of movable pieces 110a are closed, and facilitates the reception of the game ball when the pair is open. Above the right side of the second starting port 110, a winning gate 112 for detecting the passing of the game ball and performing a lottery of a normal symbol for opening the second starting port 110 for a predetermined time is arranged. Below the second start opening 110, there is arranged a big prize opening opening / closing device 120 that opens the door 120a for a certain period of time when a big hit game (long win game) is started. At the bottom of the game area 103, a collection port 121 for collecting game balls that have not entered any of the entrances is arranged.

  When the game ball enters the first start port 106 or the second start port 110, the symbol display unit 105 starts to display a plurality of decorative symbols, and stops the variation of the decorative symbols after a predetermined time has elapsed. If a specific symbol (for example, “777”) is prepared at the time of stoppage, it means that the right to execute the jackpot game (long win game) is acquired, and then the jackpot game (long hit game) is started. When a big hit game (long win game) is started, the opening / closing door 120a of the big prize opening / closing device 120 is repeatedly opened for a predetermined time (for example, 15 times), and a prize ball corresponding to the game ball entered. Will be paid out.

  Production moving parts 125, 125 ′, 126, and 127 (see FIG. 4) are arranged on the left and right sides, upper, and lower sides of the symbol display unit 105. These movable parts are configured to be movable in a predetermined direction. The effect power transmission mechanism of the effect movable part 116 disposed above the symbol display unit 105 will be described later.

  A frame member 130 having a shape surrounding the game area 103 and projecting from the game board 101 to the player side is disposed on the outer peripheral portion of the game board 101, and a plurality of lights are provided above the frame member 130. An effect light 131 (lamp unit) is installed. On the lower side of the frame member 130, in addition to a tray unit to which game balls lent out from a lending device (not shown) are supplied, an operation handle is arranged. The operation handle protrudes from the game board 101 to the player side, and is operated by the player when the game ball is fired by driving the launching portion.

  Under the frame member 130, a chance button (not shown) that accepts an operation by the player is arranged. The operation of the chance button is effective while guidance for prompting the operation of the chance button is displayed, for example, in the case of a specific reach effect during the game.

  The production power transmission mechanism 10 of the production movable part 126 of the gaming machine 1 configured as described above is shown in FIG. 5 (perspective view), FIG. 6 (a) (perspective view), and FIG. 6 (b) (perspective view). As shown, the motor 11, the power transmission unit 20 that transmits the power of the motor 11, and the elevating mechanism unit 40 that receives the power from the power transmission unit 20 and raises and lowers the effect movable part 126. .

  The motor 11 is a stepping motor, and is mainly driven when moving the effect movable component 126 from the lower end position PL (see FIG. 4) to the upper end position PH (see FIG. 3). In order to stop the effect movable part 126 at the upper end position PH, the rotation amount of the rotation shaft of the motor 11 when the effect movable part 126 is set to the upper end position PH is set, and when the set amount is reached, the motor is set. The power supply to 11 is stopped. The motor 11 is attached to a housing case 21 that constitutes a part of the power transmission unit 20.

  As shown in FIG. 7 (a) (back side internal structure diagram), FIG. 8 (a) (back side internal perspective view), and FIG. 9 (disassembled perspective view), the power transmission unit 20 is opened and capped at one end side. A housing case 21 formed in a shape, a gear mechanism portion 23 rotatably supported in the housing case 21, a driven pulley 31 that rotates by receiving power from the gear mechanism portion 23, and a driven pulley 31. A wire 33, a direction changing pulley 34 for changing the feeding direction of the wire 33, and a guide pulley 35 for guiding the wire 33 fed from the direction changing pulley 34 to the effect movable component 126 side.

  The storage case 21 is formed in a rectangular shape in a side view, and includes a bottom surface portion 21a and a side wall portion 21b provided around the bottom surface portion 21a. The bottom surface portion 21 a is provided with an insertion hole 21 c for inserting the rotation shaft 11 a of the motor 11. The motor 11 is fixed to the bottom surface portion 21a with the rotating shaft 11a inserted through the insertion hole 21c from the back side of the bottom surface portion 21a. A shaft portion 21d extending in a direction orthogonal to the bottom surface portion 21a is provided in the vicinity of the insertion hole 21c. A driven gear 30 described later is rotatably attached to the shaft portion 21d.

  A gear mechanism 23 is attached to the rotating shaft 11 a of the motor 11 extending into the housing case 21. The gear mechanism 23 includes a drive gear 24 attached to the rotation shaft 11a of the motor 11 and an internal gear 25 formed on the side surface on the surface side of the drive gear 24 and rotating with the rotation of the drive gear 24 (FIG. 1B). 9), a side member 26 rotatably supported on the same axis as the rotation shaft 11a and having the internal gear 25 arranged on one surface side, and between the internal gear 25 and the side member 26, the inner gear 25 A claw member 27 (see FIG. 1B and FIG. 9) that is disposed on the inner side and is rotatably supported coaxially with the internal gear 25 and is integrally coupled to the side member 26, and the side member 26 An intermediate gear 29 that is rotatably supported and meshes with the drive gear 24, and a driven gear 30 that meshes with the intermediate gear 29 and is rotatably attached to the shaft portion 21d.

  The drive gear 24 is disposed coaxially with the rotation shaft 11a of the motor 11 and is attached to the rotation shaft 11a. For this reason, the drive gear 24 rotates with rotation of the rotating shaft 11a. A disk portion 24 a is provided on the front end side in the axial direction of the drive gear 24. The outer diameter of the disk portion 24 a has substantially the same diameter as the outer diameter of the drive gear 24. The internal gear 25 is coaxial with the rotation center axis (rotation shaft 11a) of the drive gear 24 and is formed inside the disk portion 24a. The tooth portion of the internal gear 25 is configured by continuously providing sawtooth-shaped triangular protrusions along the inner periphery of the internal gear 25 (see FIG. 1B).

  On the side surface of the drive gear 24 on the side of the internal gear, a protrusion 24b (see FIG. 9) is provided coaxially with the rotary shaft 11a to which the drive gear 24 is attached and has a larger diameter than the rotary shaft 11a. The protrusion 24b is provided with a shaft 24c that is disposed coaxially with the rotating shaft 11a and supports the side member 26.

  As shown in FIG. 1B (internal structure diagram), a claw member 27 is rotatably inserted into the protrusion 24b. The claw member 27 is made of a synthetic resin material and is integrally formed. The claw member 27 is pivotally inserted into the protrusion 24b, and one end side is connected to the rotation portion 27a and the other end side is an internal gear. The arm portion 27b that extends along the inner periphery of the arm portion 25 and is supported so as to be elastically deformable in the radial direction of the inner gear, and the claw portion 27c that is provided at the tip of the other end of the arm portion 27b and contacts the tooth portion of the inner gear 25 It has.

  The rotation part 27a is formed in an annular shape, and is fitted to the protrusion 24b so as to be rotatable. A pair of projecting portions 27d are provided on both sides of the outer periphery of the rotating portion 27a. The proximal end portion of the arm portion 27b is connected to the distal end portion of the protruding portion 27d. The claw portion 27 c is formed in a sawtooth triangular shape like the tooth portion of the internal gear 25. The claw portion 27c has a small inclined portion 27c1 having a small inclination and a large inclined portion 27c2 having a large inclination facing the inner periphery of the internal gear 25.

  In the claw member 27 configured as described above, as shown in FIG. 2B (internal structure diagram), the tooth portion of the internal gear 25 advances from the bottom side to the top side of the small inclined portion 27c1 of the claw portion 27c. When the internal gear 25 rotates in the direction of arrow A (hereinafter referred to as “one direction”), the arm portion 27b is elastically deformed and bent inside the internal gear 25 to allow the rotation of the internal gear 25 relative to the claw portion 27c. . On the other hand, as shown in FIG. 1 (b), the claw member 27 has an internal gear in a direction (arrow B direction, hereinafter referred to as "reverse direction") in which the tooth portion of the internal gear 25 approaches the large inclined portion 27c2. When 25 rotates, the tooth | gear part of the internal gear 25 will contact | abut the large inclination part 27c of the nail | claw part 27c, and the reverse rotation of the internal gear 25 will be controlled. That is, the internal gear 25 and the claw member 27 function as a one-way clutch that restricts the rotation of the internal gear 25 in only one direction.

  The rotational resistance acting on the internal gear 25 when the internal gear 25 is allowed to rotate depends on the length, thickness, material, and the like of the arm portion 27b of the claw member 27. For this reason, the rotational resistance of the internal gear 25 can be set to a desired magnitude by taking these parameters into consideration.

  A locking projection (not shown) that protrudes outward in the axial direction is formed at the axially outer end of the rotating portion 27a of the claw member 27. The engaging projection engages with the side member 26 to integrally connect the claw member 27 and the side member 26.

  As shown in FIGS. 8A and 9, the side member 26 is formed in a disc shape, and a collar portion 26 a that protrudes toward the drive gear 24 is provided in an annular shape on the outer periphery thereof. The flange portion 26a has an inner diameter slightly larger than the outer diameter of the disk portion 24a of the drive gear 24, and can cover the outer periphery of the disk portion 24a with the side member 26 inserted into the shaft portion 24c. Length.

  A through hole through which a shaft portion 24c provided in the drive gear 24 is inserted is provided at the center of the side member 26, and an insertion hole through which a locking projection provided in the claw member 27 is inserted outside the through hole. 26b (see FIG. 9) is provided. For this reason, when the locking protrusion is inserted into the insertion hole 26 b, the claw member 27 can be integrally coupled to the side member 26 in the rotational direction of the side member 26.

  A protrusion 26 c (see FIG. 8A) that protrudes outward from the outer periphery of the drive gear 24 is provided on the outer periphery of the side member 26. An intermediate gear 29 that meshes with the drive gear 24 is rotatably supported by the protrusion 26c. The intermediate gear 29 has a smaller diameter than the drive gear 24 and rotates as the drive gear 24 rotates.

  Thus, the internal gear 25 and the claw member 27 constitute a one-way clutch that restricts the rotation direction of the internal gear 25 to only one side, and the claw member 27 is a side member 26 with respect to the rotational direction of the side member 26. Are connected together. Therefore, as shown in FIGS. 2 (a) and 2 (b), when the rotation shaft 11a of the motor 11 rotates in the direction allowing the rotation of the internal gear 25 (direction of arrow A), the intermediate gear 29 is When the driven gear 30 is not meshed, the tooth portion of the internal gear 25 gets over the claw portion 27c, so that the force that bends the arm portion 27b does not act on the arm portion 27b. For this reason, the internal gear 25 and the side member 26 are integrally coupled via the claw member 27. Accordingly, as the internal gear 25 rotates, the intermediate gear 29 revolves around the rotation shaft 11a in the rotation direction (arrow A direction) of the rotation shaft 11a.

  Further, as shown in FIGS. 1A and 1B, the direction in which the rotation shaft 11 a of the motor 11 allows the internal gear 25 to rotate with the intermediate gear 29 engaged with the driven gear 30 (arrow A). In the case of rotation in the direction), the side member 26 is restricted from rotating to the driven gear 30 side because the intermediate gear 29 meshes with the driven gear 30, but the internal gear 25 is controlled by the pawl member 27. To the direction of arrow A. For this reason, the intermediate gear 29 can be rotated with the rotation of the drive gear 24.

  On the other hand, when the rotating shaft 11a of the motor 11 rotates in the reverse direction (arrow B direction) with the intermediate gear 29 engaged with the driven gear 30, the tooth portion of the internal gear 25 abuts against the claw portion 27c of the claw member 27, and the internal gear. 25 is integrated with the side member 26 via the claw member 27. Therefore, the intermediate gear 29 provided on the side member 26 revolves in the direction away from the driven gear 30 (arrow B direction) with the rotation shaft 11a of the motor 11 as the rotation center.

  The driven gear 30 is inserted into a shaft portion 21d provided in the housing case 21 (see FIG. 9) and is rotatably supported. The driven gear 30 has a larger diameter than the intermediate gear 29. As shown in FIG. 1A (internal structure diagram), the driven gear 30 is meshed between the teeth of the intermediate gear 29 and the teeth of the driven gear 30 when the intermediate gear 29 is engaged with the driven gear 30. The direction of the force F acting on the contact P at that time is arranged at a position substantially parallel to a virtual line L connecting the revolution center O of the intermediate gear 29 and the contact P. For this reason, when the rotational force of the intermediate gear 29 is transmitted to the driven gear 30, almost no force is generated in the direction in which the intermediate gear 29 is separated from the driven gear 30. Therefore, the meshing state between the intermediate gear 29 and the driven gear 30 can be maintained in a good state, and power transmission from the intermediate gear 29 to the driven gear 30 can be performed reliably. The driven gear 30 may be arranged so that the direction of the force F is inclined toward the driven gear 30 with respect to the virtual line L.

  As the intermediate gear 29 revolves toward the driven gear 30, the intermediate gear 29 meshes with the driven gear 30, but the meshing of both teeth may become shallow, or the teeth may wear due to friction or the like. . In these cases, when the direction of the force F is inclined in the direction away from the driven gear 30 with respect to the imaginary line L, the intermediate gear 29 may revolve in the direction away from the driven gear 30.

  Therefore, as shown in FIG. 11A (internal structure diagram) and FIG. 11B (internal structure diagram), the side member 26 has a tension spring 28 that biases the intermediate gear 29 toward the driven gear 30 side. Is provided. The tension spring 28 is provided between a plate-side latching portion 26d provided at the radially outer end of the side member 26 and a case-side latching portion 21e provided on the housing case 21 side. The plate side latching portion 21d is provided on the side opposite to the driven gear 30 side with respect to the intermediate gear 29, and the case side latching portion 21e is provided below the plate side latching portion 21d. The tension spring 28 is slightly extended in a state where the intermediate gear 29 and the driven gear 30 are engaged with each other, and is further extended when the intermediate gear 29 is separated from the driven gear 30. That is, the tension spring 28 is always extended. For this reason, the side member 26 always urges the intermediate gear 29 in the direction of revolving toward the driven gear 30 side.

  As shown in FIGS. 8B and 9, a locking projection 30 a for connecting to the driven pulley 31 is provided on the side surface of the driven gear 30. The driven pulley 31 is inserted into a shaft portion 21 d extending from the driven gear 30 and is rotatably supported, and an engagement recess 31 c that engages with the locking projection 30 a is provided on a side surface facing the driven gear 30. . An annular concave groove 31 a is formed on the side surface of the driven pulley 31 on the driven gear side. Further, at the peripheral edge of the driven pulley 31, one end of the wire 33 passed between the circumferential groove of the driven pulley 31 and the concave groove 31a is locked to the concave groove 31a, and the wire 33 on the other end side is connected to the circumferential groove. A hole 31b is provided to wind the wire (see FIG. 9).

  The wire 33 is wound counterclockwise when viewed from the driven gear side of the driven pulley 31.

  A cover member 37 that covers the outer periphery of the driven pulley 31 is provided on the side opposite to the driven gear side of the driven pulley 31. The cover member 37 has a disk-like side surface portion 37a disposed opposite to the side surface of the driven pulley 31 opposite to the driven gear side, and projects from the peripheral edge portion of the side surface portion 37a to the driven pulley side so that the circumferential groove of the driven pulley 31 is formed. It has a covering flange 37b. A hole portion 37c through which the shaft portion 21d can be inserted is provided in the central portion of the side surface portion 37a. The flange portion 37b is formed in an annular shape around the shaft portion 21d inserted through the hole portion 37c and extends in a direction orthogonal to the side surface portion 37a. The inner diameter of the flange portion 37 b is slightly larger than the outer diameter of the driven pulley 31, and the length dimension of the flange portion 37 b is slightly larger than the thickness of the driven pulley 31. The flange portion 37b is provided with a plurality of flange portions 37d protruding outward, and the cover member 37 is fastened to the housing case 21 via screws inserted into the flange portion 37d.

  For this reason, the driven pulley 31 is rotatably supported while being accommodated in the cover member 37.

  A notch 37e capable of exposing the circumferential groove of the driven pulley 31 is provided in the flange portion 37b of the cover member 37. The notch 37e is provided on the upper left side of the cover member 37 when the cover member 37 is viewed from the side where the driven pulley 31 is accommodated in a state where the cover member 37 is attached to the accommodation case 21. A guide portion 37f is provided on the upper portion of the notch 37e. The guide portion 37f protrudes downward in order to separate the wire 33 wound around the driven pulley 31 outwardly in the radial direction of the driven pulley 31. The guide portion 37f is formed in a triangular shape with the lower side protruding in a convex shape in a side view.

  A direction changing pulley 34 is rotatably supported on the flange portion 37b of the cover member 37 above the guide portion 37f. The direction changing pulley 34 is rotatably supported by a shaft portion 37g extending in a direction orthogonal to the lateral direction with respect to the shaft portion 21d inserted through the cover member 37. The direction change pulley 34 has a smaller diameter than the driven pulley 31, and the direction change pulley 34 is disposed so that the circumferential groove of the direction change pulley 34 is positioned above the circumferential groove of the driven pulley 31. For this reason, when the wire 33 separated from the driven pulley 31 is extended upward by the guide portion 37f, it can be wound around the circumferential groove of the direction changing pulley 34 as it is. For this reason, a possibility that the wire 33 may come off from the driven pulley 31 and the direction change pulley 34 can be suppressed.

  An overhang member 37 h (see FIG. 8A) that extends from the flange portion 37 b of the cover member 37 and extends along the outer periphery of the direction change pulley 34 to cover the circumferential groove of the direction change pulley 34. ) Is provided. A guide pulley 35 is provided below the side surface of the cover member 37. The guide pulley 35 winds the wire 33 fed from the direction changing pulley 34 and extends to the effect movable part side.

  The guide pulley 35 is rotatably supported by a shaft portion 37 i extending substantially parallel to the shaft portion 37 g that supports the direction changing pulley 34. The guide pulley 35 is disposed so that the elevating mechanism 40 is positioned on an extension line in the extending direction of the wire 33 wound around the guide pulley 35 and fed vertically downward.

  As shown in FIGS. 9 and 10, the elevating mechanism unit 40 has expansion / contraction means 41 configured to be extendable / contractible. The expansion / contraction means 41 includes a pair of first rail members 45 slidably attached to a pair of rail support substrates 43, 44 that are attached to both sides of the housing case 21 in the width direction and extend in the vertical direction, and a pair of first rails. A pair of second rail members 46 slidably attached to the rail member 45 and a slide plate 47 attached between the second rail members 47 are provided.

  A decorative plate 48 with decoration is attached between the pair of rail support substrates 43. At the lower part of the slide plate 47, a locking projection 47a for locking the lower end portion of the wire 33 fed vertically downward from the guide pulley 35 is provided. On the surface side of the slide plate 47, a disk-shaped production movable part 126 is rotatably provided. By winding and unwinding the wire 33 wound around the driven pulley 31, the elevating mechanism 40 can be expanded and contracted and attached to the slide plate 47 to elevate the effect movable part 126. It should be noted that the position of the effect movable part 126 when the elevating mechanism unit 40 is fully extended is the lower position, and the position of the effect movable part 126 when the elevating mechanism part 40 is fully reduced is the upper position. Will be described below.

  When the rotation shaft of the motor 11 rotates in one direction (in the direction of arrow A) with the production movable component 126 moved to the lower position, the production power transmission mechanism 10 configured in this way is shown in FIG. As shown in FIG. 8A, the intermediate gear 29 revolves toward the driven gear 30 and meshes, and the rotational force of the motor 11 (see FIG. 9) is transmitted through the drive gear 24, the intermediate gear 29, and the driven gear 30. Is transmitted to the driven pulley 31. As a result, the driven pulley 31 can be rotated in the direction of winding the wire 33 to move the effect movable part 126 from the lower position PL to the upper position PH.

  On the other hand, when the motor 11 is rotated in the reverse direction (arrow B direction) with the production movable component 126 moved to the upper position PH, as shown in FIGS. 2 (a) and 7 (b), the intermediate gear 29 is provided. Revolves away from the driven gear 30 and the driven gear 30 is free to rotate. As a result, the driven pulley 31 coupled to the driven gear 30 is also free, and the expansion / contraction means 41 is extended by its own weight such as the production movable part 126 provided at the lower end thereof, and the production movable part 126 is moved downward. It can be moved to position PL.

  As described above, the production power transmission mechanism 10 of the present invention is configured such that the claw member 27 is provided inside the internal gear 25 so that the reverse rotation of the internal gear 25 can be restricted when the drive gear 24 rotates reversely. As a result, the driven pulley 31 and the side member 26 are integrated when the driving gear 24 rotates in the reverse direction, the intermediate gear 29 revolves in a direction away from the driven gear 30, and the production movable part 126 can be lowered by its own weight. . For this reason, the motor reverse rotation operation for revolving the intermediate gear 29 in the direction away from the driven gear 30 may be performed when the production movable part 126 is lowered. Therefore, the load on the motor 11 is reduced, and the reduction in the motor life can be suppressed.
