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 provided with a power transmission mechanism that raises and lowers a movable part for presentation in accordance with game characteristics of a game. In this pachinko gaming machine, a frame body that is attached to surround the image display device is disposed at the center of the game board, and an effect movable part is disposed at the upper center of the frame body. The power transmission mechanism winds a wire drawn obliquely upward from a drive pulley attached to the rotating shaft of the motor around an idler pulley disposed above the movable parts for presentation, and moves the wire drawn downward from the idler pulley. The movable part for production is connected to the end.

  The idler pulley is attached to the frame and is supported so as to be rotatable about a rotation axis that faces in the front-rear direction with respect to the game board. Supported around. When the motor is driven and the wire is paid out from the drive pulley, the wire is drawn downward from the idler pulley by the weight of the effect moving part, and the effect moving part is lowered. On the other hand, when the motor is driven and the wire is wound around the drive pulley, the wire is wound around the idler pulley, and the effect moving part moves upward.

JP 2009-273533 A (see paragraph 0025, FIG. 5 and FIG. 7)

  In this conventional power transmission mechanism, if the production movable part is arranged in front of the drive pulley, the idler pulley needs to be arranged in front of the drive pulley, and the wires may be disconnected from both pulleys. Therefore, if a mechanism part (pulley, shaft transmission mechanism part, etc.) capable of transmitting the power from the drive pulley to the idler pulley is provided on the rear side of the idler pulley, the power transmission mechanism is enlarged.

  The present invention responds to such a problem, and there is a wide degree of freedom in arranging the movable parts for production with respect to the power transmission mechanism, and a power transmission mechanism for production of a gaming machine that can suppress an increase in size of the power transmission mechanism, and An object is to provide a gaming machine provided.

In order to solve such a problem, the present invention is an effect power transmission mechanism for an amusement machine that elevates and lowers an effect movable part (126) that is provided so as to be able to move up and down in a game machine. A driven pulley (31) that is supported rotatably around the (shaft portion 21d) and receives the power of the motor (11) and has a peripheral groove formed in the peripheral portion, and is disposed above the driven pulley. An upper guide portion (37f) having a surface portion extending in the width direction of the circumferential groove of the driven pulley, and provided above the upper guide portion, in a direction orthogonal to the rotation axis of the driven pulley in plan view. A direction change pulley (34) supported rotatably around an extending rotation shaft (shaft portion 37g), and disposed below the direction change pulley and above the effect moving parts, and is the same as the direction change pulley Axis of rotation A guide pulley (35) rotatably supported around the shaft portion 37i), and a wire (33) to which the effect movable part is connected, and the wire is connected to the effect movable part at one end. After the portion is connected to the driven pulley and the other end side of the wire to which the effecting movable part is connected is wound around the circumferential groove of the driven pulley and then fed out from the circumferential groove to the upper portion of the driven pulley The other end side of the wire that is hung around the surface portion of the upper guide portion and extended upward is wound by the direction changing pulley and is extended downward, and downward. The other end of the wire extended toward the end is wound by the guide pulley, and the effect moving part is connected to the other end of the wire wound by the guide pulley. (Claim 1).

  The upper guide part is for changing the direction of the wire separated from the driven pulley and extending it upward. Specifically, the upper guide portion has a surface portion that is disposed above the circumferential groove at the upper left side in the left-right direction of the driven pulley and extends in the width direction of the circumferential groove. Since the surface portion is a portion where the wire slides, the surface portion preferably has a shape that does not increase the load on the wire. The extending direction of the wire guided by the upper guide portion is preferably within the range of the width of the peripheral groove of the driven pulley so that the wire does not come off from the driven pulley.

  The direction changing pulley is for changing the direction of the wire extending upward from the upper guide portion. Specifically, the direction change pulley is provided above the upper guide portion, and is supported rotatably around a rotation axis extending in a direction orthogonal to the rotation axis of the driven pulley in a plan view, via the upper guide portion. Then, the wire extending upward is wound, and the other end side of the wire is directed downward and extended to the upper side of the effect movable part. The direction of the wire fed from the driven pulley can be freely changed by the direction changing pulley. For this reason, the freedom degree of arrangement | positioning of the production | presentation movable part with respect to a driven pulley can be widened.

  The guide pulley is for winding a wire extending from the conversion pulley and feeding it to the production movable part side. Specifically, it is disposed below the direction change pulley and above the effect moving parts, and is supported so as to be rotatable around a rotation axis facing the same direction as the direction change pulley.

  The invention of the present application is a gaming machine comprising the power transmission mechanism for performance described in claim 1 (claim 2). 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 upper guide part that hangs around the wire wound around the driven pulley and extends upward, and the upper guide part is rotatable upward. A direction change pulley that winds a wire extending from the upper guide portion and extends the other end of the wire downward, and extends to the upper side of the effect moving component, and the direction change pulley below the direction change pulley and By having a guide pulley that is arranged above and that extends from the direction change pulley to the effect movable part side, the degree of freedom of arrangement of the effect movable part with respect to the driven pulley can be increased. In addition, when changing the arrangement of the moving parts for production with respect to the driven pulley, the moving parts for production can be moved up and down only by changing the direction of the wire fed out from the direction change pulley, so a new power transmission means is unnecessary, An increase in the size of the power transmission mechanism for production can be suppressed.

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

  FIG. 2 (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 a variation display of a plurality of decorative symbols, and stops the variation of the decorative symbol 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 movable parts 125, 125 ′, 126, and 127 (see FIG. 3) are arranged on the left and right sides, the upper side, and the lower side 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. 4 (perspective view), FIG. 5A (perspective view), and FIG. 5B (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. 3) to the upper end position PH (see FIG. 2). 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. 6A (rear side internal structure diagram), FIG. 7A (rear side inner perspective view), and FIG. 8 (decomposed perspective view), the power transmission unit 20 is opened at one end side and is capped. Housing case 21 (see FIG. 8) 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 body A wire 33 wound around the pulley 31, a direction changing pulley 34 that changes the feeding direction of the wire 33, and a guide pulley 35 that guides the wire 33 drawn out from the direction changing pulley 34 to the stage movable component 126 side. It becomes.

  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. The shaft portion 21 d is a rotation shaft of the driven gear 30 by rotatably attaching a driven gear 30 to be described later.

  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 section 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. 9B). 8), a side member 26 that is rotatably supported on the same axis as the rotation shaft 11a and has an internal gear 25 disposed on one surface side, and the internal gear 25 between the internal gear 25 and the side member 26. A claw member 27 (see FIG. 9B and FIG. 8) integrally coupled to the side member 26 and rotatably supported coaxially with the internal gear 25, and the side member 26. And an intermediate gear 29 meshed with the drive gear 24 and a driven gear 30 meshed with the intermediate gear 29 and rotatably attached to the shaft portion 21d.

  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 rotating 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 triangular protrusions along the inner periphery of the internal gear 25 (see FIG. 9B).

  On the side surface of the drive gear 24 on the side of the internal gear, there is provided a protrusion 24b (see FIG. 8) that is disposed 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 projecting portion 24b is provided with a shaft portion 24c that is disposed coaxially with the rotating shaft 11a and supports the side member 26.

  As shown in FIG. 9B (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 in this manner, as shown in FIG. 10B (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. 9 (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. 7A and 8, 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 the shaft portion 24 c provided in the internal gear 25 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. 8) 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.

  On the outer periphery of the side member 26, a protruding portion 26c (see FIG. 7A) that protrudes outward from the outer periphery of the drive gear 24 is provided. 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. For this reason, as shown in FIGS. 10A and 10B, the intermediate gear 29 is driven when the rotation shaft 11a of the motor 11 rotates in the direction in which the rotation of the internal gear 25 is allowed (arrow A direction). When the gear 30 is not engaged with the gear 30, the tooth portion of the internal gear 25 gets over the claw portion 27c, so that the force for bending 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, and the intermediate gear 29 is connected to the rotary shaft 11 a with the rotary shaft 11 a as the rotation center as the internal gear 25 rotates. Revolves in the rotation direction (arrow A direction).

  Further, as shown in FIGS. 9A and 9B, the direction in which the rotation shaft 11a 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, 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. 8) and is rotatably supported. That is, the driven gear 30 is rotatably supported with the shaft portion 21d as a rotation axis. The driven gear 30 has a larger diameter than the intermediate gear 29. As shown in FIG. 9A (internal structure diagram), the driven gear 30 is on the front side in the moving direction of the intermediate gear 29 that revolves and is in contact with the driven gear 30 of the intermediate gear 29 that revolves. The extension line of the force F acting on the driven gear 30 from the intermediate gear 29 is provided at a position that does not intersect the rotation shaft 21 d of the driven gear 30.

  In this embodiment, the intermediate gear 29 to the driven gear 30 with respect to a virtual line L that connects the contact position P of the tooth portions of both gears and the rotation fulcrum Q of the driven gear 30 when the intermediate gear 29 and the driven gear 30 are engaged. The driven gear 30 is disposed at a position where the angle θ formed by the extension line of the force F acting on the shaft becomes an acute angle (about 20 degrees in the drawing).

  When the driven gear 30 is provided in this way, when the intermediate gear 29 revolves and comes into contact with the driven gear 30, the intermediate gear 29 receives the reaction force R from the driven gear 30 and stops. Since the direction of the reaction force R does not face the same direction as the imaginary line L, the magnitude of the reaction force Ra of the directional component of the reaction force R in the same direction as the imaginary line L is larger than the magnitude of the reaction force R. Further, the intermediate gear 29 is rotated by the reaction force Rb of the direction component orthogonal to the imaginary line L among the direction components of the reaction force R. For this reason, when the intermediate gear 29 abuts on the driven gear 30, the meshing depth of the intermediate gear 29 with respect to the driven gear 30 may be reduced.

  However, in this embodiment, the angle θ is about 20 degrees, and the magnitude of the direction component force Ra with respect to the magnitude of the reaction force R is slightly small. Further, the claw member 27 restricts the reverse rotation of the intermediate gear 29 via the drive gear 24. For this reason, the intermediate gear 29 receives only the reaction force Ra having the same direction component as the imaginary line L and meshes with the driven gear 30. For this reason, the meshing of the intermediate gear 29 with the driven gear 30 can be ensured, and the power transmission from the intermediate gear 29 to the driven gear 30 can be ensured.

  When the intermediate gear 29 meshes with the driven gear 30 and power is transmitted from the intermediate gear 29 to the driven gear 30, most of the rotational force of the motor 11 is transmitted to the intermediate gear 29, and the intermediate gear 29 is moved to the driven gear 30 side. The force in the revolving direction is relatively small. For this reason, the intermediate gear 29 may revolve in a direction away from the driven gear 30. If the intermediate gear 29 revolves in a direction away from the driven gear 30, the meshing depth of both gears becomes shallow, and there is a risk that power transmission from the intermediate gear 29 to the driven gear 30 will be insufficient.

  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 tension spring 28 always urges the intermediate gear 29 in the direction of revolving toward the driven gear 30 side.

  In this way, the meshing state of both gears can be kept good by the tension spring 28. As a result, the load fluctuation of the motor 11 due to the change of the meshing depth of the gear is prevented in advance, and the reduction of the motor life can be further suppressed. Further, when the intermediate gear 29 is moved from the disengaged state to the engaged state, the intermediate gear 29 and the driven gear 30 can be reliably meshed.

  On the side surface of the driven gear 30, as shown in FIGS. 7B and 8, a locking projection 30 a for coupling with the driven pulley 31 is provided. 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. 8).

  The wire 33 is wound counterclockwise when viewed from the driven gear 30 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 height 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 (see FIG. 12) 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. ing.

  As shown in FIG. 12 (rear side internal structure diagram), an upper guide portion 37f that extends the wire 33 wound around the driven pulley 31 upward is provided above the notch 37e. The upper guide portion 37 f has a surface portion 37 fa extending in the circumferential groove width direction with respect to the circumferential groove of the driven pulley 31. The surface portion 37fa is formed in a planar shape, and extends upward by hanging around the other end side of the wire 33 fed from the driven pulley 31.

  A direction changing pulley 34 is rotatably supported on the flange portion 37b above the upper guide portion 37f. The direction conversion pulley 34 is supported rotatably around a shaft portion 37g serving as a rotation shaft extending in a direction orthogonal to the shaft portion 21d serving as a rotation shaft of the driven pulley 31 in a plan view. 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 upper 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. 7A) 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 portion 37a (see FIG. 8) of the cover member 37. The guide pulley 35 winds the wire 33 fed out from the direction changing pulley 34 and extends it to the effect movable part side.

  As shown in FIG. 8, the guide pulley 35 is rotatably supported by a shaft portion 37 i that extends substantially parallel to the shaft portion 37 g that supports the direction changing pulley 34. The guide pulley 35 is arranged so that the elevating mechanism unit 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. 1 and 8, the elevating mechanism unit 40 includes an 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 46 are provided.

  A decorative plate 48 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 PL, and the position of the effect movable part 126 when the elevating mechanism part 40 is fully reduced is the upper position. The position PH will be described below.

  The effect power transmission mechanism 10 configured in this manner is shown in FIG. 7 (a) when the rotating shaft 11a of the motor 11 rotates in one direction (arrow A direction) with the effect movable component 126 moved to the lower position PL. 9A, the intermediate gear 29 revolves toward the driven gear 30 and meshes with the driven gear 30, and the rotational force of the motor 11 (see FIG. 8) is applied to the drive gear 24 and the intermediate gear 29. Then, it is transmitted to the driven pulley 31 via the driven gear 30. As a result, the driven pulley 31 can rotate in the winding direction of 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. 6 (b) and 10 (a), the intermediate gear 29 is provided. Revolves in a direction away from the driven gear 30, and the driven gear 30 becomes 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.

  In this way, in the production power transmission mechanism 10 of the present invention, as shown in FIG. 12, the wire 33 extending upward via the upper guide portion 37 f is extended to the upper side of the production movable part 126 by the direction change pulley 34. Therefore, even when the effect movable part 126 is disposed at a position away from the side surface of the driven pulley 31 on the front side in the axial direction of the driven pulley 31, the wire 33 can be connected to the effect movable part 126. For this reason, it is possible to freely arrange the production movable part 126 without changing the position of the driven pulley 31, and to widen the degree of freedom of arrangement of the production movable part 126. When changing the arrangement of the production movable part 126 with respect to the driven pulley 31, the production movable part 126 can be moved up and down only by changing the direction of the wire 33 fed out from the direction conversion pulley 34, and a new power transmission means is provided. It is unnecessary. For this reason, the enlargement of the effect power transmission mechanism 10 can be suppressed.
