JP 2008-183030 A

  The effect device described in Patent Literature 1 can only perform a simple operation of swinging the decorative body, and cannot perform a novel operation. In the conventional rendering device, it is necessary to use a plurality of power sources in order to cause the decorative body to perform a novel operation, and it is also necessary to make the structure of the rendering device complicated. Therefore, it has been difficult to cause the decorative body to perform a novel operation without increasing the cost.

  An object of the present invention is to provide an effect device capable of causing a decorative body to perform a novel operation with a simple structure using one power source, and a gaming machine including the effect device.

  The effect device according to claim 1 is an effect device that includes a motor that is driven to rotate, and that produces an effect by operating a decorative body with the power of the motor. The effect device extends in the axial direction and is rotated around the axis by the power of the motor. A first working shaft having a spiral groove or rib on the outer peripheral surface, and a guide portion guided along the groove or rib, and the rotation of the first working shaft A moving body that moves along the axial direction of the first working shaft, and a direction that is arranged in a direction parallel to the axial direction of the first working shaft, rotates around the axis by the power of the motor, and is orthogonal to the axial direction. And a second action shaft having a protrusion on the outer peripheral surface extending parallel to the axial direction, and a protrusion provided on the decorative body and protruding toward the second action axis, The decorative body is on the moving body. When the first working shaft and the second working shaft are rotated by the power of the motor, the decorative body moves along the axial direction of the first working shaft and rotates. It swings when the projection comes into contact with the projection of the second action shaft.

  In the effect device, when the motor rotates, the first action shaft and the second action shaft rotate together. When the first action shaft rotates, the decorative body pivotally supported by the moving body moves in the axial direction of the first action shaft. When the second action shaft rotates, the protrusion of the decorative body comes into contact with the protrusion of the second action shaft, and the decorative body swings. Therefore, the rendering device can be moved along the axial direction of the first action shaft while rotating the one motor while swinging the decorative body. Therefore, a novel operation of the decorative body can be realized with a small amount of power.

  The effect device according to claim 2 further includes urging means for urging the decorative body from the protrusion in the direction of the second action shaft. In the effect device, when the second action shaft rotates, the protrusion that is biased toward the second action shaft repeatedly contacts the protrusion. When the protrusion comes into contact with the protruding portion of the second action shaft, the decorative body swings in a direction away from the second action shaft. When the protrusion and the protrusion are separated from each other, the decorative body swings in a direction approaching the second action shaft by the biasing force of the biasing means. Therefore, since the effect device can swing the decorative body quickly and reliably, it is possible to cause the decorative body to perform a more characteristic operation.

  According to a third aspect of the present invention, the urging means is a coil spring wound around a shaft portion that pivotally supports the decorative body on the movable body. In the effect device, the amount of deformation of the urging means is small compared to the case where the decorative body is urged at a position away from the shaft portion. Therefore, the possibility that the urging means is damaged can be reduced. Since the amount of deformation of the urging means is small, variation in the urging force is reduced, and the decorative body can be urged smoothly.

  The stage device according to claim 4 is provided with the decoration body, and includes a swing amount regulating portion that contacts the moving body when the decoration body swings in a direction opposite to a biasing direction by the biasing means. It has more. In the effect device, the swing amount of the decorative body can be regulated to an appropriate amount by the swing amount regulating unit. Accordingly, the decorative body can be made to perform a desired swinging motion.

  In the presentation device according to claim 5, the second action axis has a shape in which a groove extending in the axial direction is formed on each of N side surfaces of an N prism (N is a natural number of 3 or more). And In the second action axis of the effect device, a ridge formed by the intersection of the two side surfaces becomes a protrusion that contacts the protrusion. When the second action shaft rotates, the projecting portion alternately repeats the contact operation with the projecting portion and the operation of entering the groove formed between the two projecting portions. Therefore, a characteristic operation can be performed by swinging the decorative body in small increments. Further, the shape of the second action shaft is simple and the manufacture is easy.

  A gaming machine according to a sixth aspect includes the effect device according to any one of the first to fifth aspects, and a control unit that controls execution of the effect by the effect device by controlling rotation of the motor. Yes. The gaming machine can execute various effects using the effect device.

  In the gaming machine according to claim 7, the motor is a step motor, and an origin for detecting whether or not the moving body is at an origin position that is a standby position when an effect by the effect device is not performed. Position detection means is further provided, and the control means is an origin confirmation that drives the step motor until the origin position detection means detects that the moving body is at the origin position during the rendering by the rendering device. Means.

  The effect device can swing the decorative body by bringing the protruding portion of the second action shaft into contact with the protrusion of the decorative body. At the time of contact between the protrusion and the protrusion, a load is applied to the second action shaft. Therefore, the step motor may step out. If the effect is continued in a state where the step motor is out of step, the gaming machine cannot cause the decorative body to execute the set operation. In particular, if the step motor steps out multiple times during a single performance, errors in the position of the decorative body accumulate, and the player feels a sense of discomfort. The game machine can check the position of the moving body by returning the moving body to the origin position during the production. Therefore, it is possible to reduce the possibility that a sense of incongruity will occur in the performance due to step-out.

  The gaming machine according to claim 8, further comprising end point position detection means for detecting whether or not the moving body is at an end position of movement by the step motor, and the control means moves the moving body to the end point. When moving to a position, the step motor is driven until the end point position detecting means detects that the moving body is at the end point position, regardless of the amount of rotation of the step motor. The gaming machine can reliably move the moving body to the end position even if a step-out occurs. Therefore, the possibility that the player may feel uncomfortable with the performance due to the step-out can be reduced.

  Note that the special symbol start electric accessory 15 and the special winning opening 16 include an opening / closing member. When the game ball passes the normal symbol start gate 12, the normal hit determination is performed. When it is determined that the normal hit is determined by the normal hit determination, the opening / closing member of the special symbol starting electric accessory 15 is opened, and a game ball can be won. When a game ball wins the special symbol starting electric accessory 15, a big hit determination is performed. When it is determined that the jackpot is determined to be a jackpot, the opening / closing member of the jackpot 16 is opened, and a game ball can be won. A symbol display unit 17 is provided on the left side of the special symbol starting electric accessory 15. The symbol display unit 17 displays a normal symbol indicating the result of the normal hit determination, a special symbol indicating the result of the jackpot determination, and the like.

On the right side of the game board 2, an effect device 20 and an effect auxiliary device 21 are provided. The effect device 20 is disposed on the right side of the display device 10. The effect device 20 produces an effect by moving up and down while swinging a decorative body 27 (see FIG. 3) formed in a tuna shape. The production assisting device 21 is disposed on the upper side of the display device 10 and includes a movable portion 22 formed in a bowl shape. The performance assisting device 21 moves the movable portion 22 in the direction of the decorative body 27 when the decorative body 27 is positioned at the upper end of the movement range. As a result, it is possible to perform an effect of capturing the tuna with a cocoon and entertain the player.

  Hereinafter, the rendering device 20 will be described with reference to FIGS. 5 to 8, the decorative body 27 is illustrated by a method different from that in FIG. 3 in order to facilitate understanding of the shape of the curved decorative body 27. As shown in FIG. 3, the rendering device 20 includes a base portion 23 that is substantially rectangular in a front view. The base part 23 includes a base part 24 and a U-shaped part 25. The base 24 includes a second guide groove 59 (see FIG. 5) described later and supports the decorative body 27 so as to be movable in the vertical direction. The U-shaped portion 25 is a U-shaped plate-like member in front view, and is fixed to the base portion 24 with screws from the front side. There is a slight gap between the base 24 and the U-shaped portion 25. An auxiliary decorative portion 26 made of a transparent synthetic resin is fixed to the rear upper end of the base portion 24. On the front side of the base portion 23, a decorative body 27 formed in a tuna shape and a shielding member 28 formed in a wave shape are disposed. The shielding member 28 is located on the front side of the decorative body 27.

  When the effect device 20 is mounted on the game board 2 (see FIG. 2), the lower half of the effect device 20 is shielded by the game board 2. Further, when the effect by the effect device 20 is not performed, as shown in FIG. 3, the decorative body 27 is located at the lower end of the moving range, and the shielding member 28 is located at the upper end of the moving range. As a result, the decorative body 27 is shielded by the shielding member 28 and the game board 2. Players get the impression that tuna lurks in the sea.

  The pachinko machine 1 moves up and down while swinging the decorative body 27 when performing the effect by the effect device 20. By moving the decorative body 27 upward, it is possible to produce an effect in which tuna appears on the sea surface from the sea. Furthermore, the pachinko machine 1 can also move the shielding member 28 positioned at the upper end of the moving range downward. The pachinko machine 1 can express how the sea surface undulates by swinging the wave-shaped shielding member 28 in the vertical direction. Then, by moving the shielding member 28 downward while moving the decorative body 27 upward, the player feels that the decorative body 27 has moved a longer distance than when only the decorative body 27 is moved upward. Can be given to. Therefore, the production by the production device 20 can be executed effectively.

  Next, the shielding member 28 and its drive mechanism will be described in detail. As shown in FIG. 3, a left support piece 29 is fixed to the central portion in the vertical direction at the left end of the shielding member 28. The left support piece 29 extends from the shielding member 28 to the back side, bends to the left, and enters the gap between the base 24 and the U-shaped portion 25. In addition, a right support piece 30 is fixed to the central portion in the vertical direction at the right end of the shielding member 28. The right support piece 30 extends from the shielding member 28 to the back surface side, bends to the right, and enters a gap between the base portion 24 and the U-shaped portion 25.

  As shown in FIGS. 4 and 5, the first motor support plate 33 is fixed horizontally on the lower left side (lower right side in FIGS. 4 and 5) slightly from the center on the back side of the base portion 24. The first motor support plate 33 supports a first motor 34 that is a step motor. The output shaft of the first motor 34 extends in the vertical direction, and a first motor gear 35 is provided on the output shaft. As shown in FIG. 4, the base 24 rotatably supports the first groove cam 40 by two concave portions 37 and 38 on the rear left side (right side in FIG. 4). The first groove cam 40 is a cylindrical member having a spiral groove on its outer peripheral surface, and is supported so that the vertical direction is the axial direction. That is, the first groove cam 40 is arranged in parallel with the output shaft of the first motor 34. The first groove cam 40 fixes the first groove cam gear 41 in the vicinity of the lower end portion. The first groove cam gear 41 is in mesh with the first motor gear 35. Accordingly, when the first motor 34 rotates, the first groove cam 40 rotates in the opposite direction to the first motor 34.

  The first groove cam 40 is inserted through the first guide portion 42. Further, the left support piece 29 (see FIG. 3) of the shielding member 28 described above includes a convex portion (not shown) extending to the back side. The convex portion is inserted through the first guide groove 43 (see FIG. 5) extending in the vertical direction at the left end of the base portion 24 and connected to the front side of the first guide portion 42. And the 1st guide part 42 has a some ball | bowl which fits into the groove | channel of the 1st groove | channel cam 40 inside, and the 1st groove | channel cam 40 and the 1st groove | channel with an internal ball | bowl are rotated when the 1st groove | channel cam 40 rotates. It moves up and down along one guide groove 43. Accordingly, when the first groove cam 40 rotates, the shielding member 28 connected to the first guide portion 42 moves up and down. A roller 31 is rotatably provided on the right support piece 30. As shown in FIG. 5, the roller 31 contacts a rail portion 32 that extends in the vertical direction at the left end of the base portion 24. Therefore, the shielding member 28 can move up and down smoothly.

  A first sensor 44 that is an optical sensor is disposed near the upper end of the first groove cam 40. The first sensor 44 detects whether or not the first guide portion 42 is located at the upper end portion of the first groove cam 40. The standby position (origin position) of the shielding member 28 when the effect by the effect device 20 is not performed is the upper end of the moving range extending in the vertical direction. That is, the first sensor 44 detects whether or not the shielding member 28 is at the origin position.

  Next, the drive mechanism of the decorative body 27 will be described in detail. As shown in FIGS. 4 and 5, the second motor support plate 48 is fixed horizontally on the lower right side (lower left side in FIGS. 4 and 5) slightly from the center on the back side of the base portion 24. The second motor support plate 48 supports a second motor 49 that is a step motor. The output shaft of the second motor 49 extends in the vertical direction, and a second motor gear 50 is provided on the output shaft. Further, as shown in FIG. 4, the base 24 supports the second groove cam 55 rotatably by the two concave portions 52 and 53 at the center in the left-right direction on the back side. Similar to the first groove cam 40, the second groove cam 55 is a cylindrical member having a helical groove on the outer peripheral surface, and is supported so that the vertical direction is the axial direction. The second groove cam 55 fixes the second groove cam gear 56 in the vicinity of the lower end portion. The second groove cam gear 56 meshes with the second motor gear 50. Therefore, when the second motor 49 rotates, the second groove cam 55 rotates in the opposite direction to the second motor 49.

  The second groove cam 55 is inserted through the second guide portion 57. As shown in FIG. 6, the second guide portion 57 includes a rod-like connection portion 58 that extends to the front side. As shown in FIG. 5, the base 24 forms a second guide groove 59 extending in the vertical direction on the front side of the second groove cam 55. The connection portion 58 of the second guide portion 57 passes through the second guide groove 59 to the front side. And the 2nd guide part 57 has a some ball | bowl which fits into the groove | channel of the 2nd groove | channel cam 55 inside. As the second groove cam 55 rotates, the second guide portion 57 moves in the vertical direction along the second groove cam 55 and the second guide groove 59 together with the ball inside.

  As shown in FIG. 4, a second sensor 74 is disposed in the vicinity of the lower end portion of the second groove cam 55. The second sensor 74 detects whether or not the second guide portion 57 is located at the lower end portion of the second groove cam 55. The stand-by position (origin position) of the decorative body 27 when the effect by the effect device 20 is not performed is the lower end of the movement range extending in the vertical direction. That is, the second sensor 74 detects whether or not the decorative body 27 is at the origin position. Further, a third sensor 75 is disposed in the vicinity of the upper end portion of the second groove cam 55. The third sensor 75 detects whether or not the decorative body 27 is located at the upper end that is the end point position of the movement range.

  As shown in FIG. 6, a substantially plate-like moving body 61 is fixed to the front side end portion of the connection portion 58 of the second guide portion 57. Rollers 62 are rotatably provided at two upper corners of the moving body 61. Although not shown, the same roller 62 is also provided at the center of the lower end of the moving body 61. The roller 62 has a shape in which a quarter of the outer surface is cut to facilitate molding. However, the notched portion does not have a special function, and the roller 62 functions in the same way as a normal cylindrical roller. As shown in FIG. 7, the roller 62 provided on the moving body 61 contacts the front surface of the base portion 24. Accordingly, the moving body 61 moves smoothly in the vertical direction together with the second guide portion 57.

  As shown in FIG. 7, a shaft portion 63 is provided at the center in the vertical direction on the front side of the moving body 61. The shaft portion 63 extends in the left-right direction, and supports the decorative body 27 so as to be swingable in the front-rear direction. A coil spring 64 is wound around the shaft portion 63 as shown in FIG. The coil spring 64 biases the decorative body 27 in a direction in which the lower part of the decorative body 27 approaches the base 24 (counterclockwise direction in FIG. 7).

  As shown in FIG. 7, the decorative body 27 includes a swing amount restricting portion 65 slightly above the shaft portion 62. The swing amount restricting portion 65 contacts the upper front portion of the moving body 61 when the upper portion of the decorative body 27 swings in a direction approaching the base portion 24 (clockwise direction in FIG. 7). As a result, the swing amount of the decorative body 27 is appropriately regulated. Although not shown, rubber that absorbs impact is disposed on the front upper portion of the moving body 61. Therefore, even when the swinging amount restricting portion 65 and the moving body 61 are in contact with each other, the generated noise is very small, and there is a low possibility that problems such as deformation of the member will occur. Further, a roller 66 is rotatably provided in the vicinity of the lower end portion on the back side of the decorative body 27. The roller 66 contacts the base 24 when the lower part of the decorative body 27 swings in a direction approaching the base 24. Accordingly, the roller 66 appropriately regulates the swinging amount of the decorative body 27 and allows the decorative body 27 to move smoothly up and down while swinging. Note that when the decorative body 27 swings, a projection 68 described below contacts the prism 70. Accordingly, the protrusion 68 also regulates the swinging amount of the decorative body 27.

  Then, as shown in FIGS. 5 to 8, a protrusion 68 is provided on the back side of the decorative body 27. The protruding portion 68 protrudes from the slightly lower side of the shaft portion 63 to the back side. As shown in FIG. 5, a groove 69 extending in the vertical direction is formed on the right side (left side in FIG. 5) slightly from the center of the base 24. The protrusion 68 passes through the groove 69 to the back side. Even when the decorative body 27 moves in the vertical direction, the protrusion 68 always protrudes toward the back side of the groove 69. The protrusion 68 contacts the ridge 71 that is the corner of the prism 70.

  The prism 70 will be described. As shown in FIGS. 4 and 5, a prism 70 is rotatably provided on the right side (the left side in FIGS. 4 and 5) slightly from the center of the back side of the base portion 24. The prism 70 is supported such that the vertical direction is the axial direction. As shown in FIG. 6, the prism 70 in the present embodiment has a shape in which valleys (corresponding to “grooves” in the present invention) extending in the axial direction are formed on each of the four side surfaces of the quadrangular prism. . Therefore, the cross section perpendicular to the axial direction of the prism 70 is a star polygon. The four ridges 71 formed by the intersection of the two side surfaces protrude in a direction perpendicular to the axial direction. The prism 70 fixes the prism gear 72 near the lower end. The prismatic gear 72 meshes with the second motor gear 50. Therefore, when the second motor 49 rotates, the prism 70 rotates in the opposite direction to the second motor 49.

  Next, the rendering operation in the rendering device 20 will be described. When the performance is not performed, as shown in FIG. 5, the decorative body 27 and the moving body 61 are located at the lower end of the moving range that is the origin position. When starting the production, the pachinko machine 1 rotates the second motor 49 counterclockwise as viewed from above. When the second motor 49 rotates, the power of the second motor 49 is transmitted to the second groove cam gear 56 and the prismatic gear 72 that mesh with the second motor gear 50, and the second groove cam 55 and the prism 70 rotate together.

  When the second groove cam 55 rotates clockwise as viewed from above, the second guide portion 57 moves upward along the second groove cam 55 and the second guide groove 59. Then, the decorative body 27 connected to the second guide portion 57 also moves upward. The pachinko machine 1 can control the vertical position and moving speed of the decorative body 27 by controlling the rotation amount of the second motor 49, which is a step motor, according to the program.

  Further, as shown in FIGS. 7 and 8, the protrusion 68 of the decorative body 27 protrudes toward the prism 70. When the prism 70 rotates and the protrusion 68 contacts the ridge 71 (see FIG. 6) of the prism 70, the lower portion of the decorative body 27 swings to the front side (left side in FIG. 7). When the protrusion 68 enters the valley between the two ridges 71, the lower part of the decorative body 27 swings to the back side. That is, when the prism 70 rotates, the decorative body 27 swings in small increments.

  Therefore, the pachinko machine 1 can move the decorative body 27 up and down while swinging (vibrating) in small increments by continuously rotating the second motor 49 in one direction. As a result, it is possible to easily produce an effect that the tuna is lifted while rampaging. Further, when the rotation direction of the second motor 49 is periodically finely changed, the decorative body 27 swings while repeating the vertical movement alternately and finely. By shortening the cycle of changing the rotation direction, it is possible to give the player the impression that the tuna repeats only rocking at the same location. Therefore, the pachinko machine 1 can not only perform the vertical movement and the swinging motion of the decorative body 27 simultaneously with one motor, but can also appear to perform only the swinging motion.

  Next, the electrical configuration of the pachinko machine 1 will be described with reference to FIG. As shown in FIG. 9, the control unit 100 includes a main board 101, a sub-integrated board 102, a lamp driver board 103, an effect control board 104, a payout control board 105, and a relay board 106.

  The sub integrated substrate 102 includes a CPU 121, a RAM 122, and a ROM 123, and is connected to the lamp driver substrate 103, the effect control substrate 104, and the speaker 8. The sub-integrated board 102 performs comprehensive control such as effects according to control commands such as effect pattern designation commands transmitted from the main board 101. Specifically, an effect pattern for controlling the operation of the effect device 20 is stored in the ROM 123. When an effect pattern designation command is received from the main board 101, a command for controlling the effect device 20 and the like is transmitted to each board in accordance with the designated effect pattern.

  The lamp driver board 103 includes a CPU 133 and the like. Based on the command received from the sub-integrated board 102 and the detection results of the first sensor 44, the second sensor 74, and the third sensor 75, the lamp driver board 103 receives the first motor 34 and the second motor of the rendering device 20. The drive of the motor 49 is controlled. The effect control board 104 includes a CPU 134 and the like, and controls display on the display device 10. The payout control board 105 includes a CPU 135 and the like, and controls the operation of the prize ball payout device 137 in accordance with a command transmitted from the main board 101.

  On the relay board 106, an electric accessory release solenoid 141 and a big prize opening solenoid 142 for opening and closing the opening and closing member, a normal symbol operation switch 143 and a big prize opening switch 144 for detecting the winning of a game ball, and a symbol display for displaying symbols. The part 17 etc. are connected. The relay board 106 relays between these switches and the main board 101. The power supply board 107 is connected to the main board 101 and the game ball launching device 108, and supplies stabilized DC power to each board and the game ball launching device 108. The game ball launching device 108 launches one game ball to the game area 4 at regular intervals.

  Next, with reference to FIG. 10, the rendering device control process performed on the sub-integrated board 102 will be described. The effect device control process is a process of controlling the effect by the effect device 20 in accordance with the command received from the main board 101. The rendering device control process is executed by the CPU 121 of the sub-integrated board 102 in accordance with a program stored in the ROM 123. The rendering device control process is started when the sub-integrated board 102 is turned on.

  First, it is determined whether or not an effect pattern designation command has been received from the main board 101 (S1). As described above, the effect pattern designation command is a command for designating an effect pattern for notifying the player of the result of the jackpot determination. If not received (S1: NO), this determination is repeated. When an effect pattern designation command is received (S1: YES), it is determined whether or not an effect pattern for executing an effect by the effect device 20 is designated (S2). If the effect pattern does not execute the effect by the effect device 20 (S2: NO), the process returns to the determination of S1 as it is.

  When an effect pattern for executing an effect by the effect device 20 is specified (S2: YES), a command for driving the first motor 34 and the second motor 49 along the specified effect pattern is sent to the lamp driver board 103. (S3). In the effect pattern, the rotation start timing, rotation stop timing, rotation direction, rotation amount (number of pulses output to the step motor), and effect end timing of the first motor 34 and the second motor 49 that are step motors are defined. . The sub-integrated board 102 can cause the effect device 20 to execute a preset effect by driving the first motor 34 and the second motor 49 along the effect pattern. Furthermore, in the production pattern, the origin confirmation timing and the movement timing to the end point position are determined. Details will be described below.

  During execution of the effect by the effect device 20, it is determined whether or not the origin confirmation timing has arrived (S4). The origin confirmation timing is a timing at which the positions of the decorative body 27 and the moving body 61 are temporarily returned to the origin position during the performance. When the origin confirmation timing has arrived (S4: YES), the second motor 49 is driven to lower the decorative body 27 and the moving body 61 (S8). The second motor 49 is driven until the second sensor 74 detects the second guide portion 57 and determines that the moving body 61 is located at the origin (S9: NO). When the decorative body 27 and the moving body 61 are located at the origin (S9: YES), the process returns to S3.

  The rendering device 20 causes the decorative body 27 to swing by rotating the prism 70 and bringing the ridge 71 into contact with the protrusion 68. At this time, since the load is applied to the prism 70, the second motor 49 may step out. If the presentation is continued in a state where the second motor 49 is out of step, the set operation cannot be executed by the decorative body 27. In particular, if the second motor 49 steps out multiple times during a single performance, errors in the positions of the decorative body 27 and the moving body 61 accumulate, and the player feels a sense of discomfort. The pachinko machine 1 can reset the error by moving the decorative body 27 and the moving body to the origin in the middle of the performance, and can reduce the possibility of the performance being continued with the step-out occurring.

  If the origin confirmation timing has not arrived (S4: NO), it is determined whether or not the timing for moving to the end point has arrived (S5). The movement timing to the end point position is a timing at which the decorative body 27 and the moving body 61 are moved to the upper end (end point position) of the movement range. The pachinko machine 1 moves the decorative body 27 to the end point position when notifying the player that it is a big hit. When the movement timing to the end point position has arrived (S5: YES), the second motor 49 is driven to raise the decorative body 27 and the moving body 61 (S11). The second motor 49 is driven until the third sensor 75 detects the second guide portion 57 and determines that the moving body 61 is located at the end point (S12: NO). When the decorative body 27 and the moving body 61 are located at the end points (S12: YES), the process returns to S3. By the above processing, even if the second motor 49 is stepped out, the decorative body 27 and the moving body 61 can be reliably moved to the end position.

  If the movement timing to the end point has not arrived (S5: NO), it is determined whether or not the production end timing has arrived (S6). If it has not arrived (S6: NO), the process returns to S3 and the production is continued. When the production end timing comes (S6: YES), the decorative body 27 and the moving body 61 are returned to the origin position (S14), and the process returns to the determination of S1. The process of S14 is the same as the process of S8 and S9.

  As described above, in the rendering device 20 of the present embodiment, when the second motor 49 rotates, the second groove cam 55 and the prism 70 rotate together. When the second groove cam 55 rotates, the decorative body 27 that is pivotally supported by the movable body 61 moves in the vertical direction that is the axial direction of the second groove cam 55. When the prism 70 rotates, the protrusion 68 of the decorative body 27 comes into contact with the ridge 71 of the prism 70 and the decorative body 27 swings. Therefore, the rendering device 20 can be moved up and down while rotating the decorative body 27 by rotating one motor. Therefore, a novel operation of the decorative body 27 can be realized with a small amount of power and a simple configuration.

  The decorative body 27 is urged by a coil spring 64 in a direction in which the protrusion 68 approaches the prism 70. When the prism 70 rotates and contacts the protrusion 68 with the ridge 71, the lower part of the decorative body 27 swings to the front side. When the prism 70 further rotates and the ridge 71 and the protrusion 68 are separated from each other, the lower portion of the decorative body 27 swings to the back side by the biasing force of the coil spring 64. Therefore, the rendering device 20 can swing the decorative body 27 quickly and reliably. Therefore, the decorative body 27 can be made to perform a more characteristic operation. Further, when the decorative body 27 is biased by the coil spring 64 wound around the shaft portion 63, the biasing means for biasing the decorative body 27 is compared with the case where the decorative body 27 is biased at a position away from the shaft portion 63. The amount of deformation is small. Therefore, the possibility that the urging means is damaged can be reduced. When the amount of deformation is small, there is little variation in the urging force, so that the decorative body 27 can be urged smoothly.

  The swing amount restricting portion 65 of the decorative body 27 contacts the moving body 61 when the upper portion of the decorative body 27 swings back. Therefore, the rendering device 20 can restrict the swing amount of the decorative body 27 to an appropriate amount by the protrusion 68 and the swing amount restricting portion 65, and can cause the decorative body 27 to perform a desired swinging motion.

  The prism 70 of the effect device 20 has a shape in which a trough extending in the axial direction is formed on each of the four side surfaces of the quadrangular prism. When the prism 70 rotates, the protrusion 68 of the decorative body 27 alternately repeats the contact operation of the prism 70 with the ridge 71 and the operation of entering the valley formed between the two ridges 71. Accordingly, the rendering device 20 can perform a characteristic operation by swinging the decorative body 27 in small increments. Further, the shape of the prism 70 is simple, and the manufacture is easy.

  The pachinko machine 1 that controls the rendering by the rendering device 20 can return the moving body 61 to the origin position during the rendering and confirm the position of the moving body 61. As a result, even when a step-out occurs in the second motor 49, the error can be reset, and the possibility that a sense of incongruity will be generated can be reduced. Further, when the pachinko machine 1 moves the moving body 61 to the end point position, the third sensor 75 is connected to the second guide portion 57 regardless of the rotation amount of the second motor 49 (the number of pulses output to the second motor 49). The moving body 61 is raised until it is detected. Accordingly, the pachinko machine 1 can reliably move the moving body 61 to the end point position even when a step-out occurs. Therefore, the possibility that the player may feel uncomfortable with the performance due to step-out can be reduced.

  The second motor 49 in the present embodiment corresponds to the “motor” of the present invention. The second groove cam 55 corresponds to a “first operation shaft”. The second guide portion 57 corresponds to a “guide portion”. The prism 70 corresponds to the “second action axis”, and the ridge 71 corresponds to the “projection”. The CPU 121 of the sub-integrated board 102 that performs the rendering device control process shown in FIG. 10 functions as a “control unit”. The second sensor 74 corresponds to “origin position detecting means”. The CPU 121 that drives the second motor 49 in S8 and S9 in FIG. 10 functions as “origin confirmation means”. The third sensor 75 corresponds to “end point position detecting means”.

  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. First, in the above-described embodiment, the second groove cam gear 56 provided on the second groove cam 55 and the prism gear 72 provided on the prism 70 are both meshed with the second motor gear 50. However, it is sufficient that the second groove cam 55 and the prism 70 are rotated together by the power of the second motor 49, and the configuration shown in the above embodiment is merely an example. For example, even if the second motor gear 50 is engaged only with the second groove cam gear 56 and the second groove cam gear 56 is also engaged with the prism gear 72, the power of the second motor 49 is the second groove cam 55 and the prism 70. Is transmitted to. Further, the output shaft of the second motor 49 may be directly connected to the second groove cam 55 or the prism 70. In this case, the number of gears can be reduced by 1, and the manufacturing cost can be reduced.

  In the above embodiment, the second groove cam 55 and the second guide portion 57 are used to move the moving body 61 in the vertical direction. However, the configuration for moving the moving body 61 can be changed as appropriate. For example, the movable body 61 can be moved by the second motor 49 even using a known cylindrical rib cam having a spiral rib on the outer peripheral surface and a nut guided by the rib of the rib cam. The moving body 61 may be moved by fixing the annular belt to the moving body 61 and driving the belt with the second motor 49.

  As described above, it is desirable that the action axis (the “second action axis” in the present invention) for swinging the decoration body 27 in contact with the protrusion 68 of the decoration body 27 is the prism 70. However, this action axis can also be changed. For example, if a triangular prism is used as the action axis, the number of swings of the decorative body 27 with respect to the amount of rotation of the action axis is reduced as compared with the case of a square pole. On the contrary, if the hexagonal column is used as the action shaft, the decorative body 27 swings in smaller increments. Therefore, the decorative body 27 can be made to perform a desired swinging operation by changing the shape of the action shaft. Further, even if a part of the cylinder is protruded in a direction away from the axis, it can be used as the action axis.

  In the above embodiment, the axial direction of the second groove cam 55 and the axial direction of the prism 70 are both vertical. However, as long as two axial directions are parallel, the second groove cam 55 and the prism 70 may be arranged in any direction. Further, the shaft portion 63 for the moving body 61 to support the decorative body 27 is arranged in the left-right direction. However, the direction of the shaft portion 63 can also be changed.

  As described above, it is desirable to urge the decorative body 27 using the coil spring 64 wound around the shaft portion 63. However, this configuration can also be changed. For example, the decorative body 27 may be biased by arranging a spring between the upper or lower portion of the decorative body 27 and the moving body 61. Further, without using the urging means for urging the decorative body 27, the center of gravity of the decorative body 27 may be adjusted, and the protrusion 68 may be brought into contact with the ridge 71 using the weight of the decorative body 27. In this case, although the swinging speed is slower than that in the above embodiment, the manufacturing cost of the rendering device 20 can be reduced.

  In the above embodiment, the decorative body 27 is caused to perform a desired operation by using step motors for the first motor 34 and the second motor 49. However, even if an inexpensive motor that cannot control the amount of rotation is used instead, it is possible to move the decorative body 27 up and down while swinging, as in the above embodiment. Needless to say, the shape of the decorative body 27 is not limited to the shape of a tuna, and the present invention can be applied to various effects. For example, in the above-described embodiment, it is possible to cause the wave-shaped shielding member 28 to perform the same swinging operation as that of the decorative body 27.
