When the motor rotates the belt, the movable end of the effect curtain moves and the effect curtain opens and closes.

JP 2009-285117 A

  Since the belt is stretched over the pulley, the pulley receives force from the belt. In the effect device described in Patent Document 1, the force applied from the belt to the pulley is transmitted to the output shaft of the motor as it is. Therefore, there has been a problem that the motor is likely to malfunction and fail such as step-out. On the other hand, when the rotation of the motor is transmitted to the pulley via the gear without directly fixing the pulley to the motor output shaft, the force applied to the motor output shaft is reduced, but a space for arranging the gear is required. become. Therefore, it has been difficult to reduce the force applied to the output shaft of the motor while securing a space.

  The present invention includes an effect device that can reduce a force applied to an output shaft of a motor while securing a space in an effect device that moves a member by rotating a belt by the power of the motor, and the effect device. An object is to provide a gaming machine.

  The rendering device according to the first aspect of the present invention is a motor driven to rotate, a drive pulley fixed around the output shaft of the motor and rotated around the shaft by the power of the motor, and spanned over the drive pulley An effect device comprising a belt and a moving body connected to the belt and moving as the belt rotates, wherein the rendering device is provided coaxially with an axis of the drive pulley, and from the drive pulley to the motor side. Includes a support shaft extending to the opposite side and a bearing portion for supporting the support shaft. In the effect device, the force transmitted from the belt to the drive pulley is not applied only to the output shaft of the motor, and the force is also distributed to the support shaft. Therefore, it is possible to reduce the force applied to the output shaft and reduce the possibility of malfunction and failure such as step-out in the motor. Further, it is not necessary to transmit the rotation of the motor to the drive pulley via the gear. Therefore, a space can be easily secured as compared with the case where a gear is used.

  The support shaft may be disposed so as to be rotatable with respect to the drive pulley and the bearing portion. In this case, the rendering device can smoothly rotate the drive pulley by reducing the frictional force generated on the support shaft while the drive pulley 53 is rotating.

  The rendering device may further include a cylindrical bush interposed between the support shaft and the bearing portion. In this case, the rendering device can further reduce the frictional force generated on the support shaft as compared with the case where the bush is not used.

  The rendering device includes a driven pulley that is provided so as to be able to approach or separate from the drive pulley and over which the belt is stretched, and a biasing unit that biases the driven pulley in a direction away from the drive pulley. Further, it may be provided. In this case, since an appropriate tension is applied to the belt, the rotational force of the motor can be reliably transmitted to the drive pulley. By applying tension to the belt, a force is applied from the belt to the drive pulley, but the drive pulley is supported by a support shaft. Therefore, the rendering device can perform the rendering smoothly by applying an appropriate tension to the belt while preventing an excessive load on the output shaft of the motor.

  A gaming machine according to a second aspect of the present invention includes the rendering device. Therefore, the gaming machine can achieve the same effects as the effect device.

  Although not shown, a control unit having various substrates is provided on the back side of the pachinko machine 1. Each board of the control unit includes a CPU, a RAM, a ROM, and the like, and controls various operations of the pachinko machine 1. For example, the main board performs a normal hit determination, a big hit determination, and the like, and controls the main control of the pachinko machine 1. The sub control board controls the right vertical movement motor 50, the left vertical movement motor 90, and the horizontal movement motor 113, which will be described later, based on the control result performed on the main board, and causes the effect device 30 to execute the effect.

  Hereinafter, the rendering device 30 will be described. First, the outline of the rendering device 30 will be described with reference to FIGS. 3 and 4. The front left side of FIG. 3 and the front side of FIG. The diagonally right back side of FIG. 3 and the back side of FIG. 4 are the back side of the rendering device 30. The left side of FIGS. 3 and 4 is the left side of the effect device 30, and the right side of FIGS. 3 and 4 is the right side of the effect device 30.

  The effect device 30 includes four partition bodies 31 to 34 for partitioning the display area of the display device 28 (see FIGS. 1 and 2) into a plurality of areas. Specifically, the effect device 30 includes a first horizontal partition body 31, a second horizontal partition body 32, a first vertical partition body 33, and a second vertical partition body 34. The first horizontal partition body 31 and the second horizontal partition body 32 (hereinafter collectively referred to as “horizontal partition bodies 31 and 32”) are rod-shaped bodies arranged on the front side of the display device 28, and The display area of the display device 28 can be partitioned in the vertical direction visually. The first vertical section 33 and the second vertical section 34 (hereinafter collectively referred to as “vertical sections 33, 34”) are rod-shaped bodies that are disposed on the front side of the display device 28. The display area of the display device 28 can be partitioned in the left-right direction by viewing.

  Each of the two horizontal sections 31 and 32 can vertically move symmetrically about the center of the display area. In a state where the horizontal partition bodies 31 and 32 are in the origin range within the movable range (the state shown in FIGS. 1 to 4), the display area of the display device 28 is partitioned into three lines substantially evenly by the horizontal partition bodies 31 and 32. Is done. When each of the horizontal division bodies 31 and 32 in the origin range moves symmetrically in a direction away from each other, the area of the central area among the areas divided in three rows is expanded. Thereafter, when each of the horizontal sections 31 and 32 reaches the end point position within the movable range, the horizontal sections 31 and 32 are positioned above and below the display area of the display device 28, and the horizontal sections of the display area are divided. Canceled.

  Each of the two vertical division bodies 33 and 34 can be laterally moved symmetrically about the central portion of the display area. In a state where the vertical partition bodies 33 and 34 are in the origin range within the movable range (the state shown in FIGS. 1 to 4), the display area of the display device 28 is partitioned into three rows substantially equally by the vertical partition bodies 33 and 34. Is done. When each of the vertical division bodies 33 and 34 in the origin range moves symmetrically in the direction away from each other (outside), the area of the central area among the areas divided in three rows increases. Thereafter, when each of the vertical sections 33 and 34 reaches the end point position within the movable range (see FIG. 13), the vertical sections 33 and 34 are positioned on the right and left sides of the display area of the display device 28. As a result, the vertical section of the display area is released.

  During the normal notification effect, all of the four partition bodies 31 to 34 are located in the origin range. As a result, the display area of the display device 28 is divided into nine areas in a grid pattern, and a demo symbol is displayed in each of the nine divided areas. When the same symbol is displayed on at least one of a total of eight lines in the vertical, horizontal and diagonal directions in the grid-like area, a big hit game is started and a large number of game balls are paid out. If at least one of the lines has the same symbol as the demo symbol stopped first and the demo symbol stopped second, a so-called reach effect is executed. In the reach effect, the pachinko machine 1 can change the size of each of the nine areas by moving the partition bodies 31 to 34. Furthermore, the pachinko machine 1 can move all of the division bodies 31 to 34 to the end point positions to release the division, and can perform a reach effect on the entire display area. When the jackpot game is started, the pachinko machine 1 releases the section and executes the effect during the jackpot game over the entire display area.

  Furthermore, the rendering device 30 includes a first decorative body 35 and a second decorative body 36 (hereinafter collectively referred to as “decorative bodies 35 and 36”). The decorative bodies 35 and 36 are vertically long members having a substantially rectangular shape when viewed from the front, and are decorated. The decorative bodies 35 and 36 are disposed further on the front side than the four partition bodies 31 to 34. During the normal notification effect, the first decorative body 35 shields a predetermined range from the right edge of the rectangular display area. Further, the second decorative body 36 shields a predetermined range from the left side edge portion of the display area. When the vertical sections 33 and 34 move a predetermined distance from the origin range toward the outer end position, the claws 124 and 125 of the contact members 120 and 121 provided on the vertical sections 33 and 34 (see FIG. 10, for details). (Described later) comes into contact with the decorative bodies 35 and 36. While the contact members 120 and 121 and the decorative bodies 35 and 36 are in contact, the decorative bodies 35 and 36 move laterally together with the vertical partition bodies 33 and 34. Therefore, when the vertical sections 33 and 34 move toward the end point position, the decorative bodies 35 and 36 move away from each other, and are positioned on the right and left sides of the display area of the display device 28. As a result, an area that can be visually recognized by the player in the display area is expanded, and the player's interest can be strongly attracted.

  The effect device 30 includes a vertical movement unit 40 (see FIG. 5) for moving the horizontal partition bodies 31 and 32 vertically. Further, the rendering device 30 includes a lateral movement unit 110 (see FIG. 9) for laterally moving the vertical partition bodies 33 and 34 and the decorative bodies 35 and 36.

  With reference to FIG. 4 to FIG. 8, a vertical movement unit 40 for moving the horizontal partition bodies 31 and 32 vertically will be described. As shown in FIG. 5, the vertical movement unit 40 includes a right vertical movement mechanism 41 provided on the right side of the effect device 30 (see FIGS. 3 and 4) and a left vertical movement mechanism 81 provided on the left side. . The main part of the right vertical movement mechanism 41 and the main part of the left vertical movement mechanism 81 are the same, and only the connection structure between the horizontal partition bodies 31 and 32 is different. Therefore, below, the right vertical movement mechanism 41 will be described mainly, and the description of the left vertical movement mechanism 81 will be simplified.

  As shown in FIGS. 6 and 7, the right vertical movement mechanism 41 includes a support plate 42 made of synthetic resin. The support plate 42 is a substantially plate-like member extending in the vertical direction, and supports the entire right side vertical movement mechanism 41. As shown in FIG. 6, the support plate 42 is formed with a long hole 43 extending in the vertical direction from the approximate center of the plate surface to the vicinity of the upper end portion. As shown in FIG. 7, the first belt connecting portion 45 fixed to the right end portion 44 of the first horizontal partition 31 has a convex portion 46 that protrudes to the back side (left side in FIG. 6). The convex portion 46 is inserted into the long hole 43. When the convex portion 46 slides in the long hole 43, the vertical movement of the first horizontal partition 31 is guided, and the movable range of the first horizontal partition 31 (that is, the rotation amount of the timing belt 60 described later) is increased. Appropriately regulated.

  As shown in FIGS. 6 to 8, the right vertical movement mechanism 41 includes a right vertical movement motor 50 that is a step motor. The right vertical movement motor 50 is fixed to a substantially disc-shaped motor bracket 51, and the motor bracket 51 is fixed to the upper end portion of the support plate 42. The output shaft 52 of the right vertical movement motor 50 extends rearward, passes through the motor bracket 51, and is fixed to the drive pulley 53. The drive pulley 53 rotates as the output shaft 52 rotates. Concave and convex teeth are formed on the outer peripheral surface of the drive pulley 53. Further, as shown in FIGS. 6 and 7, the right vertical movement mechanism 41 includes a driven pulley 54 in the vicinity of the lower end portion. A rotation shaft 55 is inserted into the driven pulley 54, and the rear end of the rotation shaft 55 is held by a pulley holding member 56. The pulley holding member 56 includes a cylindrical portion 57 protruding upward, and a coil spring 58 is wound around the cylindrical portion 57. The columnar part 57 is inserted from below into a columnar part holding member 59 having a box shape with the lower part open, and the columnar part holding member 59 is fixed to the lower end on the front side of the support plate 42. That is, the support plate 42, the columnar portion holding member 59, the pulley holding member 56, and the coil spring 58 hold the driven pulley 54 rotatably in a state in which the driven pulley 54 is biased downward (in a direction away from the driving pulley 53).

  An endless timing belt 60 is bridged between the driving pulley 53 and the driven pulley 54. Since the teeth of the timing belt 60 mesh with the teeth of the drive pulley 53, the timing belt 60 also rotates when the drive pulley 53 rotates. As described above, since the driven pulley 54 is held in a state of being biased downward, the timing belt 60 is stretched over the driving pulley 53 and the driven pulley 54 with an appropriate tension applied. As a result, the possibility that the tooth portion of the timing belt 60 drops from the tooth portion of the drive pulley 53 and moves between different teeth (so-called “tooth skip”) is reduced.

  As shown in FIGS. 5 and 6, the right vertical movement mechanism 41 includes a vertical movement guide shaft 63. The vertical movement guide shaft 63 extends straight from the upper left end to the lower left end of the support plate 42 in the vertical direction. Further, the right end portion 44 of the first horizontal partition 31 is fixed to the first belt connecting portion 45 by two screws 64 and 64. Since the vertical movement guide shaft 63 passes through the first belt connection portion 45, the vertical movement of the first horizontal partition 31 fixed to the first belt connection portion 45 is appropriately guided by the vertical movement guide shaft 63. Is done.

  As shown in FIG. 5, the right end portion of the first belt connecting portion 45 is connected to the right portion 61 that is one of the portions (the right portion 61 and the left portion 62) facing each other in the timing belt 60. In other words, when the portion of the timing belt 60 that extends from the right end of the driving pulley 53 to the right end of the driven pulley 54 is the right portion 61, and the portion that extends from the left end of the driving pulley 53 to the left end of the driven pulley 54 is the left portion 62. The first belt connecting portion 45 is connected to the right portion 61.

  The right end portion 65 of the second horizontal partitioning body 32 is fixed to the second belt connecting portion 67 by two screws 66. Since the vertical movement guide shaft 63 passes through the second belt connection portion 67, the vertical movement of the second horizontal partition 32 fixed to the second belt connection portion 67 is appropriately guided by the vertical movement guide shaft 63. Is done. The right end portion of the second belt connection portion 67 is connected to the left portion 62 of the timing belt 60.

  When the timing belt 60 rotates counterclockwise, the right portion 61 of the timing belt 60 moves upward and the left portion 62 moves downward. Therefore, when the timing belt 60 rotates counterclockwise, the first horizontal partition 31 connected to the right part 61 moves upward, and the second horizontal partition 32 connected to the left part 62 moves downward. On the other hand, when the timing belt 60 rotates clockwise, the first horizontal partition 31 moves downward and the second horizontal partition 32 moves upward. Since the movement direction of the right part 61 and the left part 62 is opposite and the movement amount is the same, the first horizontal partition body 31 and the second horizontal partition body 32 move vertically symmetrically.

  As shown in FIG. 4, a right origin sensor 68, which is an optical sensor, is disposed at the center in the vertical direction of the right vertical movement mechanism 41. In a state where the horizontal partition bodies 31 and 32 are in the origin range within the movable range (the state shown in FIG. 4), the detected piece 47 (FIG. 6) that projects to the front side from the lower right end of the first belt connection portion 45. Is located in the detection part of the right origin sensor 68. Therefore, the pachinko machine 1 determines that the right end portion 44 of the first horizontal partition 31 and the right end portion 65 of the second horizontal partition 32 are within the origin range depending on whether or not the right origin sensor 68 detects the detected piece 47. It is possible to detect whether or not it exists.

  As shown in FIG. 4, a right end point sensor 69 that is an optical sensor is disposed slightly above the right origin sensor 68. In a state where the horizontal partition bodies 31 and 32 are at the end point position within the movable range, the detected piece 47 of the first belt connecting portion 45 is positioned at the detection portion of the right end point sensor 69. Therefore, the pachinko machine 1 determines that the right end portion 44 of the first horizontal partition 31 and the right end portion 65 of the second horizontal partition 32 are at the end positions depending on whether or not the right end sensor 69 detects the detected piece 47. Whether or not there is can be detected.

  A structure for supporting the drive pulley 53 will be described. As shown in FIG. 8, the output shaft 52 of the right vertical movement motor 50 is fixed to the center of the front side (right side in FIG. 8) of the drive pulley 53. Further, a support shaft 70 is inserted into the center of the back side of the drive pulley 53 (left side in FIG. 8). That is, the output shaft 52 and the support shaft 70 are positioned on the axis of the drive pulley 53. As shown in FIGS. 6 and 8, a bearing portion 71, which is a cylindrical recess, is formed in the vicinity of the upper end portion of the support plate 42, and a cylindrical bush 72 is disposed on the bearing portion 71. . The support shaft 70 is supported by inserting the rear end side of the support shaft 70 into the bush 72. As described above, the support shaft 70 is inserted on the back side of the drive pulley 53, and the drive pulley 53 is supported by the support shaft 70. Accordingly, the force transmitted from the timing belt 60 to the drive pulley 53 is not applied only to the output shaft 52, and the force is also distributed to the support shaft 70. Therefore, the force applied to the output shaft 52 can be reduced, and the possibility of malfunction and failure such as step-out in the right vertical movement motor 50 can be reduced. Further, it is not necessary to transmit the rotation of the right vertical movement motor 50 to the drive pulley 53 via the gear. Therefore, a space can be easily secured as compared with the case where a gear is used.

  The support shaft 70 is rotatably arranged with respect to the drive pulley 53. Further, the support shaft 70 is rotatably arranged with respect to the bush 72. Therefore, the rendering device 30 can smoothly rotate the drive pulley 53 by reducing the frictional force generated in the support shaft 70 during the rotation of the drive pulley 53.

  The left vertical movement mechanism 81 will be described. The configuration of the main part of the left vertical movement mechanism 81 is the same as that of the right vertical movement mechanism 41. As shown in FIG. 5, the left vertical movement mechanism 81 includes a support plate 82 that supports the entire left vertical movement mechanism 81. A left side vertical movement motor 90 is fixed to the upper portion of the support plate 82 via a motor bracket 91. A drive pulley 93 is fixed to the output shaft (not shown) of the left longitudinal movement motor 90. The back side of the drive pulley 93 is supported by a support shaft (not shown) in the same manner as the right vertical movement mechanism 41. Below the support plate 82, a driven pulley 94 is held in a state of being biased downward by a coil spring (not shown), and a timing belt 100 is stretched around the driving pulley 93 and the driven pulley 94.

  The left end portion 84 of the first horizontal partition 31 is fixed to the first belt connection portion 85. A vertical movement guide shaft 103 extending in the vertical direction passes through the first belt connecting portion 85. Therefore, the vertical movement of the first horizontal partition 31 is appropriately guided by the vertical movement guide shaft 103. In the timing belt 100, when the portion extending from the right end of the driving pulley 93 to the right end of the driven pulley 94 is the right portion 101 and the portion extending from the left end of the driving pulley 93 to the left end of the driven pulley 94 is the left portion 102, The left end portion of the belt connecting portion 85 is connected to the left portion 102. Further, the left end portion 105 of the second horizontal partition 32 is fixed to the second belt connecting portion 107. Since the vertical movement guide shaft 103 passes through the second belt connecting portion 107, the second horizontal partitioning body 32 moves vertically smoothly. The left end portion of the second belt connecting portion 107 is connected to the right portion 101 of the timing belt 100. Therefore, when the timing belt 100 rotates clockwise, the first horizontal partition 31 and the second horizontal partition 32 move symmetrically in a direction away from each other (direction toward the end point position). When the timing belt 100 rotates counterclockwise, the first lateral partition body 31 and the second lateral partition body 32 move symmetrically in a direction in which they approach each other (a direction toward the origin range).

  Further, as shown in FIG. 4, a left origin sensor 108 is disposed at the center in the vertical direction of the left vertical movement mechanism 81. The left origin sensor 108 can detect whether or not the left end 84 of the first horizontal partition 31 and the left end 105 of the second horizontal partition 32 are within the origin range. A left end point sensor 109 is disposed slightly above the left origin sensor 108. The left end point sensor 109 can detect whether or not the left end portion 84 of the first horizontal partition body 31 and the left end portion 105 of the second horizontal partition body 32 are at the end position.

  As described above, the rendering device 30 moves the left and right end portions of the first horizontal partition 31 in the same direction at the same speed by the two moving mechanisms (the right vertical moving mechanism 41 and the left vertical moving mechanism 81). In addition, the rendering device 30 moves the left and right ends of the second horizontal partition 32 in the same direction at the same speed. Therefore, compared with the case where one end of each of the horizontal partition bodies 31 and 32 is connected to one of the timing belts 60 and 100, the load of each of the horizontal partition bodies 31 and 32 can be dispersed to reduce the load. it can. In particular, when the horizontal partition bodies 31 and 32 are moved in the vertical direction as in the present embodiment, a large load is applied to the rendering device 30. However, by moving the left and right end portions of the horizontal partition bodies 31 and 32 in the vertical direction, the load caused by the load on the horizontal partition bodies 31 and 32 can be dispersed and the performance can be performed smoothly. Further, in the rendering device 30, the horizontal partition bodies 31 and 32 are moved using the timing belts 60 and 100. Therefore, compared with the case where the groove cam etc. which have a helical groove | channel or a rib on an outer peripheral surface are used, the horizontal division bodies 31 and 32 can be moved rapidly. Further, in the rendering device 30, each of the horizontal partition bodies 31 and 32 is connected to a different part of the right timing belt 60 and is connected to a different part of the left timing belt 100. Thereby, the rendering device 30 can cause the two horizontal partition bodies 31 and 32 to execute symmetrical operations without imposing a large load on the right vertical movement mechanism 41 and the left vertical movement mechanism 81. Therefore, a novel effect of moving the two horizontal partition bodies 31 and 32 symmetrically can be smoothly executed with a simple configuration.

  With reference to FIG. 9 to FIG. 11, a lateral movement unit 110 for laterally moving the vertical sections 33 and 34 and the decorative bodies 35 and 36 will be described. As shown in FIG. 9, the lateral movement unit 110 includes an upper support 111 and a lower support 112. The upper support 111 is a synthetic resin member extending in the left-right direction, and supports various members of the lateral movement unit 110 at the upper portion. The lower support 112 is a member made of synthetic resin that extends to the left and right in parallel with the upper support 111, and guides lateral movement while supporting the lower portions of the vertical sections 33 and 34 and the decorative bodies 35 and 36.

  The lateral movement unit 110 includes a lateral movement motor 113 that is a step motor. The lateral movement motor 113 is fixed to the upper right end of the upper support 111. An output shaft (not shown) of the lateral movement motor 113 extends straight downward and is fixed to the drive pulley 115. The drive pulley 115 rotates as the output shaft of the lateral movement motor 113 rotates. Concave and convex teeth are formed on the outer peripheral surface of the drive pulley 115. Further, the lower side of the drive pulley 115 is supported by a support shaft (not shown) in the same manner as the drive pulley 53 of the right vertical movement mechanism 41 described above. Therefore, the external force does not concentrate on the output shaft, so that the influence of the load on the drive pulley 115 can be reduced.

  The lateral movement unit 110 includes a driven pulley 116 at the upper left end. The driven pulley 116 is held on the upper support 111 by a pulley holding member, a coil spring, and a columnar part holding member (not shown) similarly to the driven pulley 54 of the right vertical movement mechanism 41 described above. That is, the driven pulley is rotatably held in a state of being biased leftward (in a direction away from the driving pulley 115).

  A timing belt 117 is stretched between the driving pulley 115 and the driven pulley 116. Since the teeth of the timing belt 117 mesh with the teeth of the drive pulley 115, the timing belt 117 also rotates when the drive pulley 115 rotates. As described above, since the driven pulley 116 is held in a state of being biased to the left, the timing belt 117 is stretched between the driving pulley 115 and the driven pulley 116 with an appropriate tension applied. As a result, the possibility of tooth skipping decreases.

  As shown in FIG. 10, the first contact member 120 is fixed to the upper end portion of the first vertical partition 33. The first contact member 120 is connected to a rear portion 119 that is one of portions (front portion 118 and rear portion 119) of the timing belt 117 that face each other. In other words, in the timing belt 117, the portion extending from the front end of the driving pulley 115 to the front end of the driven pulley 116 is the front portion 118, and the portion extending from the rear end of the driving pulley 115 to the rear end of the driven pulley 116 is the rear portion 119. In addition, the first contact member 120 is connected to the rear portion 119. Since the first vertical partition 33 is fixed to the first contact member 120, the first vertical partition 33 is connected to the rear portion 119 via the first contact member 120. A second contact member 121 is fixed to the upper end portion of the second vertical partition 34. The second contact member 121 is connected to the front portion 118 of the timing belt 117.

  As shown in FIG. 11, the lateral movement unit 110 includes a first lateral movement guide shaft 122 and a second lateral movement guide shaft 123 (hereinafter collectively referred to as “lateral movement guide shafts 122 and 123”) on the upper side. Prepare. The first lateral movement guide shaft 122 and the second lateral movement guide shaft 123 extend in parallel to the left and right. A second lateral movement guide shaft 123 is inserted through the first contact member 120 fixed to the first vertical partition 33. Further, the first contact member 120 is formed with a claw portion 124 protruding to the front side. The claw portion 124 is disposed so as to sandwich the first lateral movement guide shaft 122 from above and below in a slidable state. That is, the lateral movement of the first contact member 120 is guided by the two lateral movement guide shafts 122 and 123. Therefore, the first contact member 120 can move more smoothly laterally than in the case of being guided by one guide shaft. Further, when the first contact member 120 is guided by one guide shaft, the first contact member 120 may rotate or swing around the guide shaft. In the present embodiment, by guiding the lateral movement of the first contact member 120 by the two lateral movement guide shafts 122 and 123, it is possible to prevent the first contact member 120 from rotating or swinging and causing a malfunction. it can.

  Note that the second contact member 121 fixed to the second vertical partition 34 is also guided by the two lateral movement guide shafts 122 and 123, similarly to the first contact member 120. That is, the second lateral movement guide shaft 123 is also inserted into the second contact member 121, and a claw portion 125 (see FIG. 10) that protrudes from the second contact member 121 to the front side is connected to the first lateral movement guide shaft 122. Fit together.

  As shown in FIG. 9, a vertical partition guide groove 126 extending in the left-right direction is formed in the rear portion of the upper surface of the lower support 112. The lower end of the first vertical partition 33 and the lower end of the second vertical partition 34 are fitted into the vertical partition guide groove 126 and slide. Accordingly, the lateral movement of the lower portions of the vertical partition bodies 33 and 34 is appropriately guided by the vertical partition body guide grooves 126. A movable range regulating pin 127 is provided at the center of the vertical partition guide groove 126 in the left-right direction. When the two vertical division bodies 33 and 34 move in a direction approaching each other, the lower left end portion of the first vertical division body 33 and the lower right end portion of the second vertical division body 34 come into contact with the movable range restriction pin 127 (see FIG. 9). As a result, the movable range of the vertical partition bodies 33 and 34 is appropriately regulated.

  As shown in FIG. 10, the first lateral movement guide shaft 122 is inserted through the upper end portion of the first decorative body 35. Further, the first auxiliary guide member 128 is fixed to the upper end portion of the first decorative body 35. The first auxiliary guide member 128 extends leftward from the upper end portion of the first decorative body 35. A first lateral movement guide shaft 122 is inserted through the left end portion of the first auxiliary guide member 128. That is, the lateral movement of the first decorative body 35 is appropriately guided by the upper end portion of the first decorative body 35 and the first auxiliary guide member 128. Similarly, the first lateral movement guide shaft 122 is inserted through the upper end portion of the second decorative body 36, and the second auxiliary guide member 129 is fixed. The second auxiliary guide member 129 extends rightward from the upper end portion of the second decorative body 36, and the first lateral movement guide shaft 122 is inserted into the right end portion of the second auxiliary guide member 129. The lateral movement of the second decorative body 36 is appropriately guided by its upper end and the second auxiliary guide member 129. A pin (not shown) is provided at the center of the upper support 111 in the left-right direction. When the first decorative body 35 moves to the left, the left end of the first auxiliary guide member 128 comes into contact with the pin, so that the movement amount of the first decorative body 35 is appropriately regulated. Similarly, when the second decorative body 36 moves to the right, the right end of the second auxiliary guide member 129 contacts the pin, so that the movement amount of the second decorative body 36 is appropriately regulated.

  A right coil spring 130 and a left coil spring 131 are wound around the first lateral movement guide shaft 122. The right coil spring 130 is interposed between the right wall portion 141 fixed to the right end portion of the first lateral movement guide shaft 122 and the upper end portion of the first decorative body 35, and attaches the first decorative body 35 to the left. Rush. The left coil spring 131 is interposed between the left wall 142 fixed to the left end of the first lateral movement guide shaft 122 and the upper end of the second decorative body 36, and attaches the second decorative body 36 to the right. Rush.

  An upper origin sensor 132 that is an optical sensor is disposed at the center in the left-right direction at the upper end of the upper support 111. In a state where the vertical sections 33 and 34 are in the origin range within the movable range (the state shown in FIGS. 9 and 10), a part of the first contact member 120 is positioned at the detection unit of the upper origin sensor 132. Therefore, the pachinko machine 1 can detect whether or not the vertical division bodies 33 and 34 are within the origin range depending on whether or not the upper origin sensor 132 detects the first contact member 120. Further, an upper end point sensor 133 is disposed slightly to the right of the upper origin sensor 132. The pachinko machine 1 can detect whether or not the vertical division bodies 33 and 34 are at the end point positions (positions shown in FIG. 13) depending on whether or not the upper end point sensor 133 detects the first contact member 120. it can.

  Further, as shown in FIG. 9, the lower support 112 has a first decorative body guide groove 134 formed on the upper right front side and a second decorative body guide groove 135 formed on the upper left front side. Both the first decorative body guide groove 134 and the second decorative body guide groove 135 extend in the left-right direction. In the first decorative body guide groove 134, the lower end portion of the first decorative body 35 is fitted and slides. In the second decorative body guide groove 135, the lower end portion of the second decorative body 36 is fitted and slides. Accordingly, the lateral movement of the lower portions of the decorative bodies 35 and 36 is appropriately guided by the first decorative body guide groove 134 and the second decorative body guide groove 135.

  With reference to FIG. 10, FIG. 12, and FIG. 13, the operation of the vertical partition bodies 33, 34 and the decorative bodies 35, 36 will be described. As shown in FIG. 10, when the timing belt 117 rotates clockwise in a plan view, the rear portion 119 of the timing belt 117 moves to the right, and the front portion 118 moves to the left. Therefore, when the timing belt 117 rotates clockwise in plan view, the first vertical section 33 connected to the rear part 119 moves to the right, and the second vertical section 34 connected to the front part 118 moves to the left. Moving. Since the movement direction of the front part 118 and the rear part 119 is opposite and the movement amount is the same, the first vertical division body 33 and the second vertical division body 34 move symmetrically. That is, with a simple configuration using only one set of the lateral movement motor 113 and the timing belt 117, it is possible to cause the two vertical partition bodies 33 and 34 to execute symmetrical operations.

  When the vertical sections 33 and 34 are within a predetermined distance from the origin range, the decorative bodies 35 and 36 are stationary while being urged inward by the coil springs 130 and 131. Therefore, in this state, a predetermined range from the left and right ends of the display area of the display device 28 (see FIGS. 1 and 2) is shielded by the decorative bodies 35 and 36.

  When the vertical partition bodies 33 and 34 continue to move in the direction away from each other (outside), the claw portion 124 of the first contact member 120 comes into contact with the left side of the upper end portion of the first decorative body 35 and the second contact member 121 The claw portion 125 contacts the right side of the upper end portion of the second decorative body 36. FIG. 12 shows a state in which the claw portions 124 and 125 that have been separated from each other and the decorative bodies 35 and 36 are in contact with each other. If the vertical division bodies 33 and 34 continue to move outward, the claw portions 124 and 125 and the decorative bodies 35 and 36 are in contact with each other, so that the decorative bodies 35 and 36 move outward together with the vertical division bodies 33 and 34. To do. FIG. 13 shows a state in which the vertical partition bodies 33 and 34 have reached the end point position. When the vertical sections 33 and 34 reach the end point position, the decorative bodies 35 and 36 also reach the outermost side, and the entire display area of the display device 28 (see FIGS. 1 and 2) can be viewed from the front side.

  On the contrary, when the vertical partition bodies 33 and 34 move from the end point position toward the origin position, the decorative bodies 35 and 36 are also connected to the coil springs 130 and 36 while the claw portions 124 and 125 are in contact with the decorative bodies 35 and 36. It moves inward by the urging force of 131. If the nail | claw parts 124 and 125 and the decoration bodies 35 and 36 space apart, the decoration bodies 35 and 36 will stop and only the vertical division bodies 33 and 34 will continue to move inside.

  As described above, the right vertical movement mechanism 41 of the effect device 30 according to the present embodiment can quickly move the right end portions of the horizontal partition bodies 31 and 32 by the right vertical movement motor 50 and the timing belt 60. . Further, a support shaft 70 is inserted into the drive pulley 53 fixed to the output shaft 52 of the right vertical movement motor 50, and the drive pulley 53 is supported by the support shaft 70. Accordingly, the force transmitted from the timing belt 60 to the drive pulley 53 is not applied only to the output shaft 52, and the force is also distributed to the support shaft 70. Therefore, the force applied to the output shaft 52 can be reduced, and the possibility of malfunction and failure such as step-out in the right vertical movement motor 50 can be reduced. Further, it is not necessary to transmit the rotation of the right vertical movement motor 50 to the drive pulley 53 via the gear. Therefore, a space can be easily secured as compared with the case where a gear is used.

  The support shaft 70 is rotatably arranged with respect to the drive pulley 53 and the bearing portion 71. Therefore, the rendering device 30 can smoothly rotate the drive pulley 53 by reducing the frictional force generated in the support shaft 70 during the rotation of the drive pulley 53. More specifically, the support shaft 70 is supported by the bearing portion 71 via a cylindrical bush 72. Therefore, the frictional force generated in the support shaft 70 can be further reduced as compared with the case where the bush 72 is not used. The driven pulley 54 is urged by a coil spring 58 in a direction away from the drive pulley 53. As a result, since an appropriate tension is applied to the timing belt 60, the occurrence of tooth skipping can be prevented appropriately. By applying tension to the timing belt 60, force is applied from the timing belt 60 to the drive pulley 53, but the drive pulley 53 is supported by the support shaft 70. Therefore, the rendering device 30 can smoothly perform the rendering by applying an appropriate tension to the timing belt 60 while preventing an excessive load from being applied to the output shaft 52 of the right vertical movement motor 50. The left vertical movement mechanism 81 can also achieve the same operational effects as the right vertical movement mechanism 41 described above.

  The right vertical movement motor 50 and the left vertical movement motor 90 in the present embodiment correspond to the “motor” of the present invention. The timing belts 60 and 100 correspond to the “belt” of the present invention. The 1st horizontal division body 31 and the 2nd horizontal division body 32 are equivalent to the "moving body" of this invention. The coil spring 58 corresponds to the “biasing means” of the present invention.

  The present invention is not limited to the embodiment described in detail above, and it is needless to say that various modifications can be made without departing from the gist of the present invention. In this Embodiment, the step motor is used as a motor for moving the division bodies 31-34. However, according to the present invention, even when a motor other than the step motor is used, the load applied to the output shaft of the motor can be reduced. Further, according to the present invention, the vertical partition bodies 33 and 34 and the decorative bodies 35 and 36 can be moved with a simple configuration even when a motor other than the step motor is used. It is also possible to use other belts such as a V belt instead of the timing belts 60, 100, and 117.

  As described above, when the friction generated in the support shaft 70 is taken into consideration, it is desirable that the support shaft 70 is rotatably arranged with respect to the drive pulley 53 and the bearing portion 71. However, the support shaft 70 can also be fixed to either the drive pulley 53 or the bearing portion 71. In the above embodiment, the driven pulley 54 is biased in the direction away from the drive pulley 53, thereby reducing the possibility of tooth skipping. However, the present invention can also be applied to an effect device that does not include an urging unit that urges the driven pulley 54.

  The rendering device 30 of the above embodiment vertically moves the left and right end portions of the horizontal partition bodies 31 and 32 by the right vertical movement mechanism 41 and the left vertical movement mechanism 81, respectively. However, the present invention can be applied even to an effect device that moves a moving body by connecting one place of the moving body to a belt. It goes without saying that the moving direction of the moving body is not limited to the vertical direction, and may be the left-right direction or the diagonal direction. The present invention can be applied not only to an effect device that moves a moving body in a straight line but also to an effect device that moves in a curved line.

  In the above embodiment, as guide members for guiding the movement of the partition bodies 31 to 34, the longitudinal movement guide shafts 63 and 103, the first lateral movement guide shaft 122, and the second lateral movement guide shaft 123, which are cylindrical shafts. Is used. However, it is also possible to use a groove part, a rib, a prism, etc. as a guide member. Instead of the coil springs 58, 130, 131, other urging means such as a leaf spring may be used.

  In the above embodiment, two guide members (the first lateral movement guide shaft 122 and the second lateral movement guide shaft 123) are provided to guide the lateral movement of the vertical partition bodies 33, 34 and the decorative bodies 35, 36. It has been. However, the present invention can be realized even if there is one guide shaft for guiding the lateral movement. In the above-described embodiment, the movement of the contact members 120 and 121 is guided by the two guide members, so that the contact members 120 and 121 move smoothly while preventing the contact members 120 and 121 from swinging. Let However, the contact members 120 and 121 can be moved by a single guide member. The movement of the contact members 120 and 121 and the movement of the decorative bodies 35 and 36 may be guided by different guide members. The movement of the first contact member 120 and the movement of the second contact member 121 may be guided by different guide members.
