Description

  The present invention relates to an effect device for a gaming machine disposed on a decorative member facing a symbol display device that performs a game effect by variably displaying symbols.

  A pachinko machine, which is a typical gaming machine, has a decorative member (also referred to as a center accessory) disposed at a substantially central position of a game area defined on a board surface of a gaming board set in the machine. A symbol display device for playing a desired symbol variation game by varying and stopping and displaying various symbols in an opening formed in the member is configured. Then, the game balls hit on the board surface (game area) of the game board win a start winning device arranged at a position below the decorative member, so that a symbol variation game is performed on the symbol display device. ing. Also, in many pachinko machines, a movable effect device provided with a effect body that performs a required operation is arranged on the decorative member, and the movable body is operated in accordance with the symbol variation game on the symbol display device. This improves the production effect.

For example, the effect device includes a fixed member fixed to the game board, and a movable member that is supported by an arm member with respect to the fixed member and is close to and away from the fixed member. Have been proposed (see Patent Document 1). In the rendering device disclosed in Patent Document 1, the rear end of the arm member is armed by the peripheral surface of a flat disk cam in which the distance from the motor output shaft to the outer peripheral portion continuously changes from the minimum length to the maximum length. The movable member is held in a state of being close to the fixed member by pressing from the upper side so as to lift the front end side. Then, by rotating the cam by the motor, the separation distance from the output shaft of the peripheral surface of the cam changes from the maximum length to the minimum length, and as a result, the movable member falls downward by its own weight and separates from the fixed member. It is like that.

The connecting hole 64 of the arm 50 is a long hole extending in the left-right direction (see FIG. 12), and is against the arm-side boss 78 a of the slide base 78 that linearly moves up and down along the slide hole 28. The left and right shifts in the connecting portion 50b of the arm 50 that is vertically displaced in an arc shape around the support portion 50a are allowed. Thereby, in the rendering device 20, the rotational displacement of the arm 50 is appropriately converted into the linear displacement of the base 72.

  The base body 74 is a rectangular plate-like member, and is disposed with its length extending in the vertical direction. A first rail 74a and a second rail 74b are projected from the front surface of the base main body 74 so as to be separated from each other in the left-right direction. The first rail 74 a and the second rail 74 b are formed over the base body 74. The base cover 76 is set to a size that matches the base body 74, and a moving hole 77 is opened by extending the length vertically on the front side of the first rail 74 a. The base cover 76 is made of a transparent member so that the first rack 82, the second rack 84, and the transmission gear 86 sandwiched between the base body 74 and the base cover 76 can be seen from the front side. It is easy to confirm the positional relationship of these members in the manufacturing process. The base main body 74 and the slide base 78 are respectively provided with protrusions on the left and right side edges of the surface facing the front half body 26 to minimize the contact area with the front half body 26.

  The base 72 is positioned in the upper stage where the base body 74 overlaps the front side of the installation recess 26b of the front half body 26 at the upper limit position of the arm 50, and the upper stage is supported by the arm 50 supported by the support part 44 and held in the posture. It is held in position (see FIG. 5 (a) or FIG. 8 (a)). Further, the base 72 is configured to be displaced downward by its own weight together with the downward displacement of the connecting portion 50b of the arm 50. The base 72 is restricted from being displaced downward at a lower position where the body-side boss 78b of the slide base 78 contacts the lower end edge of the slide hole 28, and extends downward from the installation recess 26b at the lower position. (See FIG. 5B or FIG. 8B). Here, in the effect device 20, the lower body side boss 78 b is restricted by the lower end edge of the slide hole 28, thereby restricting the downward displacement of the base 72 and the downward displacement of the arm 50 coupled to the base 72. Is regulated. That is, the lower end edge of the slide hole 28 functions as a stopper 28a for receiving the lower main body boss 78b. This stopper 28a is not only displaced downward of the base 72 but also the support portion 44 is detached from the receiving portion 60 by its own weight. The arm 50 that is displaced downward is received.

  The rendering device 20 of the embodiment includes an auxiliary stopper 36 in addition to the stopper 28a described above. The auxiliary stopper 36 is formed to project toward the rear side at the lower part of the inner surface of the left side portion of the front half body 26 (see FIG. 11). Further, the auxiliary stopper 36 is disposed so as to overlap the lower side of the support portion 50a side from the installation portion 57 in the front extension portion 54, and is configured to support the lower surface of the front extension portion 54 at the lower limit position of the arm 50 ( (Refer FIG.8 (b)). Thus, by providing the auxiliary stopper 36, the load applied when the falling arm 50 is received can be dispersed, and the burden on the stopper 28a can be reduced. In addition, since the auxiliary stopper 36 is provided on the support portion 50a side of the arm 50 with respect to the stopper 28a, the load input to the auxiliary stopper 36 when receiving the falling arm 50 can be reduced.

  The first and second racks 82 and 2, which displace the effector K further vertically relative to the base 72, are opposed to the front surface of the base main body 74 so as to be spaced apart from each other in the left-right direction. 84 and a transmission gear 86 rotatably disposed on the base body 74 between the racks 82 and 84 in a state of being engaged with the first rack 82 and the second rack 84, respectively (FIG. 5, FIG. (See FIGS. 8 to 10). The first rack 82 and the second rack 84 are connected via a transmission gear 86, and the other rack 84 is rotated under the rotation of the transmission gear 86 on the side opposite to the displacement direction of the one rack 82 (84) with respect to the base 72. (82) is configured to be displaced relative to the base 72.

  The first rack 82 is fitted with the first rail 74a of the base body 74 in a first rail groove 82a that is recessed vertically on the rear surface (see FIG. 4), and the front surface is held by the base cover 76. And is slidable in the vertical direction. The first rack 82 is disposed on the right side of the base 72. The first rack 82 is provided with a tooth portion extending vertically on the left side surface facing the second rack 84, and this tooth portion is pivotally supported between the base body 74 and the base cover 76 in the center of the base 72. The transmission gear 86 is engaged with the transmission gear 86. Further, the first rack 82 is set smaller than the vertical dimension of the base body 74. The first rack 82 is overlapped with the front surface of the base main body 74 so that the upper ends thereof are aligned with each other, and the first rack 82 is positioned within a range facing the front surface (FIG. 5A or FIG. 8A). The second position (see FIG. 5B or FIG. 8B) displaced downward from the first position and extending downward from the lower end of the base body 74 with respect to the base 72. It is configured to be slidable. In the first position, the lower portion of the tooth portion of the first rack 82 is opposed to the transmission gear 86 (see FIG. 8A), and the distance from the lower portion of the tooth portion to the upper end is the downward displacement of the first rack 82. This is an allowable rack displacement distance. The rack displacement distance of the first rack 82 is shorter than the displacement distance between the upper position and the lower position of the base 72.

  The second rack 84 is fitted with the second rail 74b of the base body 74 in a second rail groove 84a that is recessed vertically on the rear surface (see FIG. 4), and the front surface is held by the base cover 76. And is slidable in the vertical direction. The second rack 84 is arranged on the left side of the base 72 so as to be separated from the left side of the first rack 82. Further, the second rack 84 is provided with a tooth portion extending vertically on the right side surface facing the first rack 82, and the tooth portion meshes with the transmission gear 86. Further, the second rack 84 is set substantially the same as the vertical dimension of the base body 74. The second rack 84 is positioned so that the entirety of the second rack 84 overlaps with the front surface of the base body 74 and falls within the range facing the front surface in the first position of the first rack 82 (FIG. 5A or FIG. 8). (see (a)), the second rack 82 is configured to be displaced to a position protruding upward from the upper end of the base body 74 (see FIG. 5B or FIG. 8B). In the second rack 84, the transmission gear 86 is engaged with the central portion of the tooth portion at the position (first position) where the second rack 84 is aligned and overlapped with the base body 74 (see FIG. 4).

  The first rack 82 is always biased downward, and accordingly, the second rack 84 is always biased upward via the transmission gear 86. In the embodiment, by setting the total weight of the first rack 82 and the rendering body K provided in the first rack 82 to be heavier than the second rack 84, the first rack 82 is lowered by its own weight including the attached member. Be energized by.

  A pair of effector side bosses 83 and 83 are provided on the front surface of the first rack 82 so as to be spaced apart from each other in the vertical direction. The first rack 82 attached to the first rail 74 a is interposed through the movement hole 77 of the base cover 76. Thus, the pair of production-body-side bosses 83, 83 face the front side. In addition, a slide block 88 serving as an installation base of the production body K is attached to the front ends of the production body-side bosses 83 and 83 and located on the front side of the base cover 76. The movement hole 77 is formed so as to allow displacement between the first position and the second position in the first rack 82, and at the second position of the first rack 82, the lower effector side boss is formed at the lower end edge thereof. 83 is configured to abut (see FIG. 8B). In the movable mechanism portion 70, the lower effect body-side boss 83 is restricted from being displaced downward by the lower end edge of the moving hole 77, and the first rack 82 falling by its own weight is held at the second position. That is, in the movable mechanism 70, the lower end edge of the moving hole 77 functions as a rack stopper 77a that restricts the downward displacement of the first rack 82 relative to the base 72 at the second position. In the movable mechanism 70, the downward displacement of the first rack 82 is restricted by the rack stopper 77a, so that the upward displacement of the second rack 84 is restricted.

  The case 22 is provided with a restricting portion 38 projecting in a hook shape so as to cover the upper portion of the installation recess 26a from the front surface at the upper right edge of the front half body 26, and the restriction portion 38 is attached to the installation recess 26a. It is disposed above the second rack 84 (see FIG. 3). Then, the upper end of the second rack 84 abuts against the restricting portion 38, whereby the upward displacement relative to the base 72 is restricted by the restricting portion 38 (see FIG. 8A). Here, in the movable mechanism section 70, the second rack extends from the upper stage position of the base 72 to an intermediate position between the upper stage position and the lower stage position (in the embodiment, the rack displacement distance of the first rack 82). It is comprised so that the upper end of 84 may contact | abut the control part 38 (refer FIG.9 (b)). The movable mechanism 70 is configured such that the upper end of the second rack 84 is separated from the restricting portion 38 between the intermediate position of the base 72 and the lower position. In addition, when the base 72 is displaced up and down, the movable mechanism unit 70 has the effector-side boss 83 of the second rack 84 moved to the moving hole 77 at the same time or in the vicinity when the upper end of the second rack 84 is separated (abutted) from the regulating unit 38. It is set so as to abut (separate) the rack stopper 77a.

  Specifically, in the movable mechanism 70, the first rack 82 urged downward by its own weight between the upper stage position and the intermediate position of the base 72 is displaced upward while being in contact with the regulating part 38. It is in a state of being supported by the regulated second rack 84 via the transmission gear 86. That is, in the movable mechanism portion 70, the upper end of the second rack 84 is restricted from being displaced upward by the restricting portion 38 under the downward bias of the first rack 82 at the upper position of the base 72. Is held at the first position aligned with the base 72 (see FIG. 8A). At this time, the production body K is in the raised position. When the base 72 is displaced downward while the second rack 84 and the restricting portion 38 are in contact with each other, the movable mechanism portion 70 moves away from the restricting portion 38. The rack 84 is displaced so as to extend upward from the base 72, and accordingly, the first rack 82 is allowed to be displaced downward. In addition, when the base 72 is displaced upward in a state where the second rack 84 and the restricting portion 38 are in contact with each other, the movable mechanism 70 moves closer to the restricting portion 38 and the second rack 84 is moved by the restricting portion 38 to the base 72. Therefore, the first rack 82 is displaced upward via the transmission gear 86. In the movable mechanism portion 70 of the embodiment, the upper end of the second rack 84 is separated from the restricting portion 38 in a free state between the intermediate position of the base 72 and the lower stage position, but the first rack 82 has a rack stopper 77a. And held in the second position. In the movable mechanism portion 70, the effect body K is in the lowered position at the lower position of the base 72. As described above, the movable mechanism unit 70 is configured such that the first rack 82 is displaced upward or downward according to the upward or downward displacement distance of the base 72 between the upper position and the intermediate position of the base 72. .

  The effect body K includes a decorative cover 90 that constitutes the design surface of the effect body K, and light emitting means 92 that is fitted inside the decorative cover 90 (see FIG. 6). The decorative cover 90 is a cylindrical member opened to the rear side, and is configured by giving a required pattern to a light-transmitting member whose front surface is opaque. The light emitting means 92 is composed of a circular substrate 93 assembled from the rear side of the decorative cover 90 and a plurality of LEDs 94 as light emitters arranged on the front surface of the substrate 93, and the substrate 93 is interposed via the wiring holding piece 95. Are attached to the slide block 88 and connected to the first rack 82. The wiring holding piece 95 holds a wiring (not shown) connected to a connector (not shown) provided on the back side of the board 93 and a connector 96 a provided on the relay board 96 attached to the installation recess 26 b of the case 22. The wiring which has the groove | channel 95a and is connected to the production body K displaced as the 1st rack 82 and the base 72 are displaced up and down is prevented from interfering with other members. In the effect device 20, not only a dynamic effect in which the effector K is displaced up and down by the movable mechanism 70 that is interlocked with the operation of the drive mechanism 40, but also an effect by light in the effector K by the blinking of the LED 94 of the light emitting means 92. Is done.

  The effect device 20 includes position detection means 100 that detects the rising position that is the origin of the effect body K, and is configured to control the motor M by the control means P based on the detection result of the position detection means 100. The effect device 20 is configured such that when the arm 50 is at the upper limit position, the effect body K is arranged at the raised position, so that the position detection means 100 detects the upper limit position of the arm 50 (FIG. 4 or FIG. 8). (See (a)). In the embodiment, a photosensor 100 including a light emitting unit and a light receiving unit is used as the position detection unit. The photosensor 100 is attached to the rear half body 24 with the light emitting portion and the light receiving portion that are separated in the left-right direction facing the accommodation space 22a, and the right end portion (the end portion on the connection portion 50b side) of the arm 50 at the upper limit position. (Refer to FIG. 8A). On the other hand, a detection piece 66 protruding backward is provided at the right end of the arm 50. The detection piece 66 faces between the light emitting part and the light receiving part in the photosensor 100 at the upper limit position of the arm 50, and when the arm 50 is out of the upper limit position, the detection piece 66 comes out between the light emitting part and the light receiving part. (See FIGS. 8 to 10). Then, the photosensor 100 determines that the effector K is in the raised position on the condition that the detection piece 66 is located between the light emitting unit and the light receiving unit (in the embodiment, the control unit P will be described later). The sub control board P2) is configured to output to P.

  Under the control of the control means P, the effect device 20 links the effect body K in conjunction with the symbol display device S provided in the pachinko machine, light emitting devices such as LEDs and lamps, sound output means, or other effect devices. Operate and light up. As shown in FIG. 7, the control means P includes a main control board P1 that comprehensively controls the entire pachinko machine, and sub-general control that controls the symbol display device S, the light emitting device, and the like under the control of the main control board P1. And a substrate P2. In the pachinko machine, the main control board P1 and the sub control board P2 are electrically connected via the signal relay terminal board Pa. In addition, the pachinko machine of the embodiment includes a lamp relay terminal plate Pb, a lower LED substrate Pc provided on the lower side of the decorative member 14, and a right LED substrate Pd provided on the right side of the decorative member 14. The motor M and the photosensor 100 are electrically connected to the sub integrated control board P2 via the lamp relay terminal board Pb, the lower LED board Pc, and the right LED board Pd. Is input to the sub integrated control board P2. The sub integrated control board P2 controls the motor M to be driven or stopped based on the signal of the main control board P1 and the position information of the effect body K by the photosensor 100, and also the light emitting means 92 of the effect body K, the lower LED board Pc. Further, lighting control of the LEDs on the right LED substrate Pd is performed.

(Effects of Example)
Next, the effect | action of the production | presentation apparatus 20 which concerns on an Example is demonstrated. The effect device 20 is assumed to be in the ascending position (the arm 50: the upper limit position, the base 72: the upper position, the first rack 82: the first position) where the effect body K is in the standby posture (FIG. 5A). Or refer to FIG. In addition, even if the effect body K is in the ascending position, the effect device 20 has the LED 94 of the light emitting means 92 by the control means P in accordance with the winning of the symbol variation game or the game ball in the symbol display device S to the winning device. Is turned on, and the effect by the light of the effector K is performed together with or independently of the light emission of the LEDs of the lower LED substrate Pc and the right LED substrate Pd.

  The stage device 20 is controlled so that the stage body K performs a predetermined stage operation by the sub-integrated control board P2 when a symbol variation game or a game ball in the symbol display device S wins a winning device or the like. First, in the rendering device 20, the motor M of the drive mechanism section 40 is driven to rotate, and the driven gear 42 is rotated counterclockwise, so that the support section 44 positioned at the upper end of the displacement path at the ascending position of the rendering body K. Is displaced counterclockwise while supporting the receiving portion 60. At this time, in the receiving portion 60 of the embodiment, the left end which is the front side in the rotation direction of the support portion 44 is slightly curved downward at the upper limit position of the arm 50, so that the arm 50 is slightly displaced downward from the upper limit position. To do. That is, since the production body K is slightly displaced downward from the ascending position, the player can have a sense of expectation and can draw attention to the production body K, and the production effect of the operation in which the production body K described later is greatly displaced is high. Become.

  In the effect device 20, the arm 50 loses the support portion on the connection portion 50b side when the driven gear 42 further rotates and the support portion 44 is disengaged from below the receiving portion 60 at a position displaced from the upper end of the displacement path. The connection portion 50b side falls due to its own weight (see FIG. 5B or FIG. 8B). The arm 50 is stopped at the lower limit position when the main body side boss 78b of the movable mechanism 70 is received by the stopper 28a. Further, the arm 50 is supplementarily received by the auxiliary stopper 36 provided on the inner surface of the case 22 at a portion of the arm 50 closer to the support portion 50a than the connecting portion 50b. Here, the receiving portion 60 of the arm 50 is displaced not through the left region of the driven gear 42 that is the displacement path of the supporting portion 44 from the upper position toward the lower position, but through the right region of the driven gear 42. Without being interfered with, the arm 50 can be displaced rapidly down to the lower limit position. In the rendering device 20, since the detection piece 66 is detached from the photosensor 100 and shifts to a non-detection state when the arm 50 is displaced downward from the upper limit position, the drive mechanism 40 is operated in the control means P. You can judge that.

  It is assumed that the effect device 20 does not displace the arm 50 to the lower limit position even if the effect device 20 is detached from the support portion 44 from the receiving portion 60 due to a catch of the movable mechanism portion 70 or the effect body K. In the rendering device 20, if the downward displacement failure of the arm 50 occurs, the auxiliary receiving portion 62 of the arm 50 extends on the displacement path from the upper position to the lower position of the support portion 44. Before 44 reaches the lower position, it contacts the auxiliary receiving portion 62 from above (see FIG. 14). As a result, the arm 50 is pushed down via the auxiliary receiving portion 62 due to the displacement of the support portion 44 accompanying the rotation of the driven gear 42 and is reliably displaced to the lower limit position. Further, since the auxiliary receiving part 62 is retracted outside the displacement path of the support part 44 at the lower limit position of the arm 50, the auxiliary receiving part 62 is pushed down after the arm 50 is pushed down while the auxiliary receiving part 62 and the support part 44 are in contact with each other. 62 does not interfere with the support portion 44, and it is possible to operate the effect device 20 as it is (see FIG. 8B). Similarly, the auxiliary receiving portion 62 does not function when the arm 50 is displaced downward as usual. In this way, the rendering device 20 can eliminate minor problems such as poor downward displacement of the arm 50 due to catching of the movable mechanism unit 70 or the rendering body K, etc., without bothering humans.

  In the movable mechanism 70, the base 72 drops as the arm 50 drops from the upper limit position. At this time, the base 72 is displaced upward with respect to the base 72 of the second rack 84 as the base 72 moves away from the restricting portion 38. Since it is allowed, the first rack 82 is displaced downward with respect to the base 72 by its own weight. Here, the base 72 is stopped at the lower position with the main body side boss 78b locked to the stopper 28a in the same manner as the arm 50, and the first rack 82 is locked with the effector side boss 83 locked to the rack stopper 77a. It stops at the 2 position (see FIG. 5B or FIG. 8B). As described above, in the effect device 20, when the arm 50 is dropped from the upper limit position to the lower limit position all at once, the base 72 reaches the lower position all at once and the first rack 82 is displaced downward to the second position. As a result, the effector K falls to the lowered position all at once (see FIG. 3). In addition, the production body K is a raised position by a distance obtained by adding a rack displacement distance from the first position to the second position with respect to the base 72 in the first rack 82 to a displacement distance from the upper position to the lower position with respect to the case 22 in the base 72. Can be displaced greatly downward. Moreover, although the effector K is largely displaced from the raised position to the lowered position, it is accompanied by the free fall of the arm 50, the base 72, and the first rack 82, so that the displacement speed can be increased. . That is, the production body K is displaced quickly and greatly downward, thus giving a great impact to the player and a high production effect.

  In the lower limit position, the arm 50 is inclined downwardly from the bent portion 52 of the arm 50 toward the connecting portion 50b side from the support portion 50a side, and the receiving portion 60 is moved from the lower position of the support portion 44 to the upper position. It extends diagonally so as to intersect the displacement path to (Fig. 9 (a)). That is, in the drive mechanism unit 40, the support unit 44 that has arrived at the lower position as the driven gear 42 rotates contacts the receiving unit 60 that extends forward in the rotation direction, so that the support unit 44 moves from the lower position to the upper position. With the rotational displacement, the arm 50 is pushed up from the lower limit position to the upper limit position (see FIG. 9B).

  On the other hand, in the movable mechanism 70, the base 72 is also displaced upward as the arm 50 is displaced upward. At this time, the first rack 82 remains in the second position until the upper end of the second rack 84 comes into contact with the restricting portion 38. It is displaced upward together with the base 72 (see FIG. 9A). In the movable mechanism portion 70, the base 72 is further displaced upward, and the upper end of the second rack 84 abuts against the restricting portion 38, whereby the upward displacement of the second rack 84 relative to the case 22 is restricted (FIG. 9). (See (b)). When the base 72 is displaced upward with the upper end of the second rack 84 in contact with the restricting portion 38, the movable mechanism portion 70 is engaged with the second rack 84 whose position is restricted with respect to the case 22. Since the transmission gear 86 that is displaced upward along with the base 72 rolls, the first rack 82 is displaced upward from the second position (see FIG. 10A). That is, the position of the second rack 84 does not change with respect to the case 22, the base 72 is displaced upward, and the first rack 82 is weighted by its own weight and the effector K by the upward displacement distance of the base 72. It is displaced upward against the downward urging caused by this. Thus, in the movable mechanism 70, in addition to the upward displacement of the base 72, the upward displacement of the first rack 82 with respect to the base 72 is started, and the upper end of the second rack 84 abuts against the restricting portion 38. The rising speed of the effect body K is faster than when the upper end of the second rack 84 is in contact with the restricting portion 38.

  When the driving mechanism 40 reaches the upper limit position, the detection piece 66 is detected by the photosensor 100, the motor M is stopped, and the arm 50 is held at the upper limit position, so that the base 72 is held at the upper position. At the same time, the first rack 82 is held at the first position against the downward urging caused by its own weight or the like by the upper displacement restriction of the second rack 84 by the restriction portion 38 (see FIG. 10B). That is, the effect body K is held at the raised position (see FIG. 1). At this time, in the rendering device 20, the base 72 in the raised position is aligned with the installation recess 26 b so as not to protrude from the case 22, and the first rack 82 and the second rack 84 overlap the front surface of the base body 74, so Become.

  According to the production device 20, the arm 50 that is displaced downward by its own weight is received by the stopper 28a provided on the case 22, so that the load supporting force is greater than that of the case 22 that is a fixed member for convenience of rotation. The load is not applied to the moving members such as the support portion 44, the driven gear 42, the drive gear 46, and the motor M, which are inferior to the above. That is, the rendering device 20 avoids adverse effects on the axial displacement and deformation of moving members such as the support portion 44, the driven gear 42, the drive gear 46, and the motor M, or the connected state of these members. The arm 50, the production body K, etc. which comprise can be operated smoothly. In addition, since the production device 20 receives the arm 50 with a relatively strong stopper 28a, it is possible to drop the arm 50 in a free state, even if the production body K is heavy and has a large displacement distance. The arm 50 can be stopped appropriately. In addition, since the stopper 28a is also used for restricting the downward displacement of the movable mechanism 70, the number of components can be reduced and the entire mechanism can be simplified.

  The drive mechanism 40 supports the front side of the arm 50 between the support part 50a and the connection part 50b of the arm 50 with the ridges 32, 32, and the displacement of the arm 50 to the rear side with the positioning piece 58. It is regulated under contact with the latter half body 24. That is, even if the drive mechanism 40 rapidly displaces the arm 50 from the upper limit position toward the lower limit position, the drive mechanism unit 40 can displace the arm 50 without rattling in the accommodation space 22a. In addition, since the drive mechanism unit can suppress rattling even when the support portion 50a and the connection portion 50b of the arm 50 are separated from each other, the arm 50 is set long and the displacement width of the connection portion 50b is set. Can be increased, and the effector K can be displaced more greatly.

  The effect device 20 is not limited to the displacement distance of the base 72 but can greatly displace the effect body K within a range in which the rack displacement distance of the first rack 82 is combined with this displacement distance. Can improve. For example, in order to obtain a displacement range similar to that of the production body K of the embodiment with a single rack, a rack with the same length as the displacement range is required. There is a harmful effect of protruding downward and interfering with other members. On the other hand, in the production device 20 of the embodiment, the base 72 or the first rack 82 having the same length as the displacement range of the production body K is not necessary, and the vertical dimension of the base 72 and the first rack 82 can be suppressed. . In addition, since the first rack 82 and the second rack 84 are arranged within the range facing the base 72 at the upper position of the base 72 (see FIG. 8A), the entire apparatus is further downsized. In addition, it is possible to avoid the interference between the base 72 or the first rack 82 and other members and to effectively use the space of the game board 10. Thus, according to the production | presentation apparatus 20, space saving of the whole apparatus and the big operation | movement of the production body K can be made compatible.

  The effect device 20 simply rotates the motor M in one direction at a constant speed, and the effect body K is rapidly displaced downward from the ascending position. Can be changed. That is, the rendering device 20 can achieve an effective rendering operation of the rendering body K with simple control. Further, since the movable mechanism section 70 is configured such that the first rack 82 is vertically displaced in accordance with the vertical displacement of the base 72, no separate driving means is required to displace the first rack 82. Thus, by moving the arm 50 up and down by one motor M, the base 72 and the first rack 82 can be displaced up and down, so the number of parts can be reduced and the manufacturing cost can be kept low.

(Example of change)
In addition, it is not restricted to the thing of the Example mentioned above, A various change is possible as follows.
(1) A configuration in which a plurality of performance bodies are provided and each of them is moved up and down may be used.
(2) In the embodiment, the driving means and the base are arranged in the case as the fixing portion, but the driving means and the base may be directly attached to the decorative member. In this case, the decorative member becomes the fixed portion.
(3) In the embodiment, the first rack is always biased downward by setting the total weight of the first rack and the effect body provided in the first rack to be heavier than the second rack. However, the present invention is not limited to this configuration, and a configuration in which the first rack is biased downward by an elastic means such as a spring or rubber may be employed. In addition, by biasing the second rack upward, the first rack is indirectly biased downward via the transmission gear by the upward biasing of the second rack, and can be employed in the present invention.
(4) The driving means is not limited to a motor, and various rotary actuators such as a rotary solenoid can be used.
