The movable effect control circuit 320 includes a step motor drive circuit 330 that drives a step motor 280, and an extension. An end portion side position sensor S1 and a proximal end portion position sensor S2 are provided.

  Both the extended end side position sensor S1 and the proximal end side position sensor S2 are configured by a photointerpreter. The extended end side position sensor S1 is an extended end side of the longitudinal guide hole 231a provided in the left arm-shaped guide member 230a at the light emitting part and the light receiving part that receives light from the light emitting part. It is provided in the part which opposes via the terminal part 234a.

  Accordingly, when the roller 233b is positioned at the extended end side end portion 234a (see FIG. 3) among the two rollers 233a and 233b sliding along the inside of the longitudinal guide hole portion 231a (see FIG. 3). Light incident on the light receiving unit from the light emitting unit of the side position sensor S1 is blocked. That is, the extension end portion side position sensor S1 detects that the left movable decorative member main body 221a has reached the center side of the support wall 210a based on the arrival of the roller 233b at the extension end portion end portion 234a.

  In other words, when the left movable decorative member main body 221a reaches the center side of the support wall 210a, the right movable decorative member main body 221b that operates in conjunction with the left movable decorative member main body 221a also reaches the central side of the support wall 210a. Thus, the extended end side position sensor S1 detects that the movable decorative members 220a and 220b are closed (see FIG. 3).

  On the other hand, the base end side position sensor S2 is a base end side of the longitudinal guide hole portion 231a provided in the left arm-shaped guide member 230a at the light emitting portion and the light receiving portion that receives light from the light emitting portion. It is provided in the part which opposes via the terminal part 235a.

  Thereby, when the roller 233a is located at the base end side end portion 235a among the two rollers 233a and 233b sliding along the inside of the longitudinal guide hole portion 231a (see FIG. 7), the base end side position Light incident on the light receiving portion from the light emitting portion of the sensor S2 is blocked. That is, the base end side position sensor S2 detects that the left movable decorative member main body 221a has reached the left outer edge side of the support wall 210a based on the arrival of the roller 233a at the base end side end portion 235a.

  In other words, when the left movable decorative member main body 221a reaches the left outer edge side of the support wall 210a, the right movable decorative member main body 221b that operates in conjunction with the left movable decorative member main body 221a is also on the right outer edge side of the support wall 210a. Thus, the base end position sensor S2 detects that the movable decorative members 220a and 220b are open (see FIG. 7).

  The movable effect device 200 includes a coil spring 260. As shown in FIG. 4, the coil spring 260 is sandwiched between the base end portions 251a and 251b of the left and right racks 250a and 250b. In the first embodiment, the coil spring 260 is described later. As such, it acts as a compression spring.

  Here, let N be the length (natural length) of the coil spring 260 when no external force is applied to the coil spring 260. On the other hand, when the reciprocating operation is repeated while the left and right racks 250a and 250b are separated or approached, the distance L between the base end portions 251a and 251b changes as follows with a constant working width. That is, the distance when the base end portions 251a and 251b are in the most separated state (see FIG. 4) is the maximum stroke interval L1, and the base end portions 251a and 251b are in the closest state (see FIG. 8). Is the minimum stroke interval L2.

  Here, in the first embodiment, the natural length N of the coil spring 260 is set longer than the maximum stroke interval L1 between the base end portions 251a and 251b. Thus, the coil spring 260 is sandwiched between the base end portions 251a and 251b of the left and right side racks 250a and 250b that reciprocate, and is always in a compressed state. This acts to push the gap between the portions 251a and 251b. This means that the coil spring 260 acts as a compression spring so as to push the gap between the base end portions 251a and 251b.

  In the first embodiment configured as described above, the movable decorative members 220a and 220b are in a closed state as shown in FIGS. 3 and 4, and the left and right movable decorative member bodies 221a and 221b are closest to each other. In position (see FIG. 3). At this time, the base end portions 251a and 251b of the left and right racks 250a and 250b are at the farthest positions, and the distance L between them is in the state of the maximum stroke L1 (see FIG. 4).

  At this time, the roller 233b is positioned at the extended end portion side end portion 234a of the longitudinal guide hole portion 231a (see FIG. 3), and the extended end portion position sensor S1 is movable as described above. It is detected that the members 220a and 220b are in a closed state.

  Here, the operation of the coil spring 260 in a state where the movable decorative members 220a and 220b are closed will be described. In the left meshing mechanism GS1 that transmits the drive from the step motor 280 to the left movable decorative member main body 221a, between the pinion 241 and the spur gear 244, between the spur gear 244 and the first tooth portion 253a, and the second tooth portion. There is play between 254a and the sector gear portion 274a due to mechanical assembly errors including backlash.

  Here, when the movable decorative members 220a and 220b are closed, the distance between the base end portions 251a and 251b of the left and right racks 250a and 250b that reciprocate in conjunction with this is the maximum stroke distance L1 (see FIG. 4), which is shorter than the natural length N of the coil spring 260. Therefore, in this state, the coil spring 260 is in a compressed state, and acts to push the gap between the base end portions 251a and 251b. Accordingly, the left rack 250a is always pushed toward the left outer edge side (right side in FIG. 4) of the support wall 210a, and the above-described play is absorbed.

  On the other hand, in the right meshing mechanism GS2 that transmits the drive of the step motor 280 to the right movable decorative member main body 221b, between the pinion 241 and the spur gear 242, between the spur gear 242 and the spur gear 243, and between the spur gear 243 and the first gear 243. There is a backlash generated due to a mechanical assembly error including backlash between the first tooth portion 253b and between the second tooth portion 254b and the third tooth portion 274b.

  Therefore, the coil spring 260 is in a compressed state as described above, and acts to increase the distance between the base end portions 251a and 251b of the left and right racks 250a and 250b. As a result, the right rack 250b is always pushed toward the right outer edge side (left side in FIG. 4) of the support wall 210a, and the above-described play is absorbed.

  As described above, when the movable decorative members 220a and 220b are closed (see FIG. 3), the base end portions 251a and 251b of the left and right racks 250a and 250b are pushed apart by the action of the coil spring 260. Correspondingly, the left and right movable decorative member bodies 221a and 221b approach each other by the action of the left and right side racks 250a and 250b and the left and right side longitudinal connecting members 270a and 270b. Has been drawn in the direction.

  At this time, when the movable decorative member 220a, 220b shifts from the open state to the closed state and stops or reverses in the closed state and shifts to the open state again, the movable decorative member 220a, 220b The decorative members 220a and 220b can exhibit a uniform moving operation and stopping operation.

  In such a state, when the reach state is reached during the control of the gaming state by the main control circuit 300, a start signal for the reach effect program is output to the movable effect control circuit 320 via the sub control circuit 310. Thus, when the movable effect control circuit 320 starts executing the reach effect program, the step motor 280 is driven via the step motor drive circuit 330 as shown in FIG. On the other hand, corresponding to this, the light emitting diode groups LED1 to LED4 included in the decorative pieces 222a to 222d are driven through the light emitting diode driving circuit 340 in accordance with the reach production program.

  In the left meshing mechanism GS1, in FIG. 4, when the step motor 280 rotates counterclockwise, the pinion 241 rotates in the same direction (counterclockwise) as the step motor 280. Accordingly, the spur gear 244 rotates counterclockwise (clockwise) with respect to the pinion 241 while meshing with the pinion 241.

  Accordingly, the first tooth portion 253a included in the left rack 250a moves to the center side (left side in FIG. 4) of the support wall 210a under meshing with the spur gear 244, so that the left rack 250a is It moves to the center side (left side in FIG. 4) of the support wall 210a.

  Thus, the sector gear portion 274a of the left longitudinal connecting member 270a meshing with the second tooth portion 254a included in the left rack 250a moving to the center side (right side in FIG. 3) of the support wall 210a is Move to the center side (right side in FIG. 3). The left longitudinal connecting member 270a rotates around the support shaft 273a (see FIG. 5), whereby the other end 272a of the left longitudinal connecting member 270a is positioned on the left outer edge side (in FIG. 3). Move to the left).

  As the other end 272a of the left longitudinal connecting member 270a moves to the left outer edge side of the support wall 210a in FIG. 3, the left end connecting member 270a is connected to the connecting hole 275a that opens in the vicinity of the other end 272a. The roller 233a and the accompanying roller 233b slide along the longitudinal guide hole 231a in the base end direction (left direction in the figure) of the left arm-shaped guide member 230a and are connected to the rollers 233a and 233b. The left movable decorative member main body 221a and the decorative pieces 222a and 222b are moved in the left direction in the figure.

  On the other hand, in the right meshing mechanism GS2, in FIG. 4, when the step motor 280 rotates counterclockwise and the pinion 241 rotates in the same direction (counterclockwise) as the step motor 280, the spur gear 242 is moved accordingly. The pinion 241 rotates counterclockwise (clockwise) when engaged with the pinion 241. Accordingly, the spur gear 243 rotates counterclockwise (counterclockwise) with the spur gear 242 while meshing with the spur gear 242.

  Accordingly, the first tooth portion 253b included in the right rack 250b moves to the center side (right side in FIG. 4) of the support wall 210a under meshing with the spur gear 243, whereby the right rack 250b. Moves to the center side (right side in FIG. 4) of the support wall 210a.

  As a result, the third tooth portion 274b of the right longitudinal connecting member 270b meshing with the second tooth portion 254b of the right rack 250b moving to the center side (left side in FIG. 3) of the support wall 210a is supported by the support wall 210a. To the center side (left side in FIG. 3). The right-side longitudinal connecting member 270b rotates around the support shaft 273b (see FIG. 6), whereby the other end portion 272b of the right-side longitudinal connecting member 270b is positioned on the right outer edge side (in FIG. 3). Move to the right).

  As the other end portion 272a of the right longitudinal connecting member 270b moves to the right outer edge side of the support wall 210a in FIG. 3, the right end connecting member 270b is connected to the connecting hole portion 275b that opens in the vicinity of the other end portion 272b. The roller 233c and the accompanying roller 233d slide along the longitudinal guide hole 231b in the direction of the base end of the right arm-shaped guide member 230b (the right direction in the drawing) and are connected to the rollers 233c and 233d. The right movable decorative member main body 221b and the decorative pieces 222c and 222d are moved rightward in the drawing.

  In this state, the movable decorative members 220a and 220b are in a stage of shifting from a closed state to an open state. The operation of the coil spring 260 in the transition state of the movable decorative members 220a and 220b will be described. In the stage where the movable decorative members 220a and 220b shift from the closed state to the opened state, the distance between the base end portions 251a and 251b of the left and right racks 250a and 250b is the minimum stroke distance L1 (see FIG. 4). It is in the middle of the stroke interval L2 (see FIG. 8).

  Even in this state, the length of the coil spring 260 is shorter than its natural length N. Therefore, the coil spring 260 is in a compressed state, and acts to widen the distance between the base end portions 251a and 251b. Thus, even in the transition state, the left rack 250a is always pushed toward the left outer edge side (the right side in FIG. 4) of the support wall 210a, and the above-described play is absorbed.

  On the other hand, the coil spring 260 is also compressed with respect to the right rack 250b as described above, and the right rack 250b is always pushed toward the right outer edge side (left side in FIG. 4) of the support wall 210a. The above-mentioned backlash is absorbed.

  Next, when the rollers 233a and 233b move to the proximal end side along the longitudinal guide hole 231a and the roller 233a reaches the proximal end side end portion 235a of the longitudinal guide hole 231a, the proximal end side The position sensor S2 detects that the left movable decorative member main body 221a has reached the left outer edge side of the support wall 210a based on the arrival of the roller 233a at the base end side end portion 235a. Thus, the movable effect control circuit 320 controls the stop or inversion of the left and right movable decorative members 220a and 220b according to the control program.

  At the same time, the rollers 233c and 233d move to the proximal end side along the longitudinal guide hole 231b, and the roller 233c reaches the proximal end portion 235b of the longitudinal guide hole 231b. At this time, the base end side position sensor S2 provided at the base end side end portion 235a of the longitudinal guide hole 231a of the left arm-shaped guide member 230a at the symmetrical position is used as the base end side end portion 235a of the roller 233a. As described above, the movable effect control circuit 320 controls the stop or inversion of the left and right movable decorative members 220a and 220b according to the control program. At this time, the movable decorative members 220a and 220b are in an open state (see FIG. 7).

  Here, the action of the coil spring 260 in a state where the movable decorative members 220a and 220b are opened will be described. In the state in which the movable decorative members 220a and 220b are opened, as shown in FIG. 8, the interval between the base end portions 251a and 251b of the left and right racks 250a and 250b is the minimum stroke interval L2, Shorter than length N. Therefore, the coil spring 260 is in a compressed state, and acts to widen the distance between the base end portions 251a and 251b. Thus, the left rack 250a is always pushed toward the left outer edge side (right side in FIG. 8) of the support wall 210a, and the above-described backlash is absorbed.

  On the other hand, the coil spring 260 is also compressed with respect to the right rack 250b as described above, and the right rack 250b is always pushed toward the right outer edge side (left side in FIG. 8) of the support wall 210a. The above-mentioned backlash is absorbed.

  Thus, in the state where the movable decorative members 220a and 220b are opened (see FIG. 7), the base end portions 251a and 251b of the left and right racks 250a and 250b are pushed apart by the action of the coil spring 260. Correspondingly, the left and right movable decorative member bodies 221a and 221b approach each other by the action of the left and right side racks 250a and 250b and the left and right side longitudinal connecting members 270a and 270b. Has been drawn in the direction.

  At this time, when the movable decorative member 220a, 220b shifts from the closed state to the open state, and stops or reverses in the open state and shifts to the closed state again, The movable decorative member bodies 221a and 221b on both sides are attracted to each other, and the movable decorative members 220a and 220b can perform uniform moving and stopping operations.

  As described above, the movable effect device 200 is between the closed state and the opened state of the left and right movable decorative members 220a and 220b via the left and right side meshing mechanisms GS1 and GS2 under the drive of the step motor 280. Move the to repeat the production operation.

  As described above, the right and left side meshing mechanisms GS1 and GS2 include backlash generated due to mechanical assembly errors including backlash at a plurality of locations.

  Therefore, in the first embodiment, as described above, the coil spring 260 is sandwiched between the base end portions 251a and 251b of the left and right side racks 250a and 250b included in the left and right side meshing mechanisms GS1 and GS2. The coil spring 260 acts as a compression spring. That is, the natural length N of the coil spring 260 is longer than the maximum stroke interval L1 between the base end portions 251a and 251b.

  Thus, while the left and right movable decorative members 220a and 220b are repeatedly moved between the closed state and the opened state, the coil spring 260 always acts to push the gap between the left and right racks 250a and 250b. That is, the left and right racks 250a and 250b move while receiving force in the direction of the left and right outer edges of the support wall 210a during the reciprocating operation.

As a result, the play existing in the left and right side meshing mechanisms GS1 and GS2 is absorbed, and the movable decorative members 220a and 220b can perform uniform moving and stopping operations while repeating the opening and closing operations. In any case, the appearance of the effect by the movable effect device 200 can be ensured satisfactorily.
(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the second embodiment, the coil spring 260 employs a coil spring that acts as an extension spring as described later, instead of the one that acts as the compression spring of the first embodiment. The other configuration of the movable effect device 200 of the second embodiment is the same as that of the first embodiment (see FIGS. 3 and 4).

  Here, as in the first embodiment, the length (natural length) of the coil spring 260 when no external force is applied to the coil spring 260 is N, and the base end portions 251a and 251b of the left and right racks 250a and 250b are set to N. Is the maximum stroke interval L1, and the distance when each base end 251a, 251b is closest (see FIG. 8) is the minimum stroke interval L2. To do.

  Here, the coil spring 260 according to the second embodiment is sandwiched over the entire length between the base end portions 251a and 251b of the left and right racks 250a and 250b as shown in FIG. In the embodiment, the coil spring 260 acts as an extension spring as will be described later.

  Here, in the second embodiment, the natural length N of the coil spring 260 is always set shorter than the minimum stroke interval L1 between the base end portions 251a and 251b. Thus, when the coil spring 260 is sandwiched between the base end portions 251a and 251b that reciprocate, the coil spring 260 is always in an extended state. It acts to pull back the interval of 251b. This means that the coil spring 260 acts as an extension spring so as to pull back the distance between the base end portions 251a and 251b.

  In the second embodiment configured as described above, the operation of the movable effect device 200 and the operation of the coil spring 260 will be described. At this stage, the movable decorative members 220a and 220b are in a closed state as shown in FIGS. 3 and 4, and the left and right movable decorative member bodies 221a and 221b are in the closest positions (see FIG. 3). At this time, the base end portions 251a and 251b of the left and right side racks 250a and 250b included in the left and right side meshing mechanisms GS1 and GS2 are located at the farthest positions, and the distance L between them is in the state of the maximum stroke L1. Yes (see FIG. 4).

  At this time, the roller 233b is positioned at the extended end portion side end portion 234a of the longitudinal guide hole portion 231a (see FIG. 3), and the extended end portion position sensor S1 is movable as described above. It is detected that the members 220a and 220b are in a closed state.

  Here, the operation of the coil spring 260 in a state where the movable decorative members 220a and 220b are closed will be described. In the left meshing mechanism GS1 that transmits the drive from the step motor 280 to the left movable decorative member main body 221a, as described in the first embodiment, the backlash occurs due to mechanical assembly errors including backlash. Exists.

  In the second embodiment, when the movable decorative members 220a and 220b are closed, the distance between the base ends 251a and 251b of the left and right racks 250a and 250b that reciprocate in conjunction with the movable decorative members 220a and 220b is the maximum stroke distance L1. Yes (see FIG. 4), longer than the natural length N of the coil spring 260. Therefore, in this state, the coil spring 260 is in an extended state, and acts to pull back the distance between the base end portions 251a and 251b. As a result, the left rack 250a is always pulled back to the center side (left side in FIG. 4) of the support wall 210a, and the above-described play is absorbed.

  On the other hand, the right meshing mechanism GS2 that transmits the drive of the step motor 280 to the right movable decorative member main body 221b also occurs due to mechanical assembly errors including backlash as described in the first embodiment. There is backlash.

  Therefore, the coil spring 260 is in an extended state as described above, and acts to pull back the distance between the base end portions 251a and 251b of the left and right racks 250a and 250b. As a result, the right rack 250b is always pulled back to the center side (right side in FIG. 4) of the support wall 210a, and the above-described play is absorbed.

  As described above, when the movable decorative members 220a and 220b are closed (see FIG. 3), the base end portions 251a and 251b of the left and right racks 250a and 250b are pulled back by the action of the coil spring 260. Correspondingly, the left and right movable decorative member bodies 221a and 221b correspondingly move away from each other by the action of the left and right racks 250a and 250b and the left and right long connecting members 270a and 270b.

  In such a state, when the reach state is reached during the control of the gaming state by the main control circuit 300, a start signal for the reach effect program is output to the movable effect control circuit 320 via the sub control circuit 310. Thus, when the movable effect control circuit 320 starts executing the reach effect program, the step motor 280 is driven via the step motor drive circuit 330 as shown in FIG. On the other hand, corresponding to this, the light emitting diode groups LED1 to LED4 included in the decorative pieces 222a to 222d are driven through the light emitting diode driving circuit 340 in accordance with the reach production program.

  In the left meshing mechanism GS1, in FIG. 4, when the step motor 280 rotates counterclockwise, the pinion 241 rotates in the same direction (counterclockwise) as the step motor 280. Accordingly, the spur gear 244 rotates counterclockwise (clockwise) with respect to the pinion 241 while meshing with the pinion 241.

  Accordingly, the first tooth portion 253a included in the left rack 250a moves to the center side (left side in FIG. 4) of the support wall 210a under meshing with the spur gear 244, so that the left rack 250a is It moves to the center side (left side in FIG. 4) of the support wall 210a.

The left longitudinal connecting member 270a rotates around the support shaft 273a (see FIG. 5), whereby the other end 272a of the left longitudinal connecting member 270a is positioned on the left outer edge side (in FIG. 3). Move to the left).

  As the other end 272a of the left longitudinal connecting member 270a moves to the left outer edge side of the support wall 210a in FIG. 3, the left end connecting member 270a is connected to the connecting hole 275a that opens in the vicinity of the other end 272a. The roller 233a and the accompanying roller 233b slide along the longitudinal guide hole 231a in the base end direction (left direction in the figure) of the left arm-shaped guide member 230a and are connected to the rollers 233a and 233b. The left movable decorative member main body 221a and the decorative pieces 222a and 222b are moved in the left direction in the figure.

  On the other hand, in the right meshing mechanism GS2, in FIG. 4, when the step motor 280 rotates counterclockwise and the pinion 241 rotates in the same direction (counterclockwise) as the step motor 280, the spur gear 242 is moved accordingly. The pinion 241 rotates counterclockwise (clockwise) when engaged with the pinion 241. Accordingly, the spur gear 243 rotates counterclockwise (counterclockwise) with the spur gear 242 while meshing with the spur gear 242.

  Accordingly, the first tooth portion 253b included in the right rack 250b moves to the center side (right side in FIG. 4) of the support wall 210a under meshing with the spur gear 243, whereby the right rack 250b. Moves to the center side (right side in FIG. 4) of the support wall 210a.

  As a result, the third tooth portion 274b of the right longitudinal connecting member 270b meshing with the second tooth portion 254b of the right rack 250b moving to the center side (left side in FIG. 3) of the support wall 210a is supported by the support wall 210a. To the center side (left side in FIG. 3). The right-side longitudinal connecting member 270b rotates around the support shaft 273b (see FIG. 6), whereby the other end portion 272b of the right-side longitudinal connecting member 270b is positioned on the right outer edge side (in FIG. 3). Move to the right).

  As the other end portion 272a of the right longitudinal connecting member 270b moves to the right outer edge side of the support wall 210a in FIG. 3, the right end connecting member 270b is connected to the connecting hole portion 275b that opens in the vicinity of the other end portion 272b. The roller 233c and the accompanying roller 233d slide along the longitudinal guide hole 231b in the direction of the base end of the right arm-shaped guide member 230b (the right direction in the drawing) and are connected to the rollers 233c and 233d. The right movable decorative member main body 221b and the decorative pieces 222c and 222d are moved rightward in the drawing.

  In this state, the movable decorative members 220a and 220b are in a stage of shifting from a closed state to an open state. The operation of the coil spring 260 in the transition state of the movable decorative members 220a and 220b will be described. In the stage where the movable decorative members 220a and 220b shift from the closed state to the opened state, the distance between the base end portions 251a and 251b of the left and right racks 250a and 250b is the minimum stroke distance L1 (see FIG. 4). It is in the middle of the stroke interval L2 (see FIG. 8).

  Even in this state, the length of the coil spring 260 is longer than its natural length N. Therefore, the coil spring 260 is in an extended state and acts to pull back the distance between the base end portions 251a and 251b. Thus, even in the transition state, the left rack 250a is always pulled back to the center side (left side in FIG. 4) of the support wall 210a, and the above-described play is absorbed.

  On the other hand, the coil spring 260 is also extended with respect to the right rack 250b as described above, and the right rack 250b is always pulled back to the center side (right side in FIG. 4) of the support wall 210a. The above-mentioned backlash is absorbed.

  Next, when the rollers 233a and 233b move to the proximal end side along the longitudinal guide hole 231a and the roller 233a reaches the proximal end side end portion 235a of the longitudinal guide hole 231a, the proximal end side The position sensor S2 detects that the left movable decorative member main body 221a has reached the left outer edge side of the support wall 210a based on the arrival of the roller 233a at the base end side end portion 235a. Thus, the movable effect control circuit 320 controls the stop or inversion of the left and right movable decorative members 220a and 220b according to the control program.

  At the same time, the rollers 233c and 233d move to the proximal end side along the longitudinal guide hole 231b, and the roller 233c reaches the proximal end portion 235b of the longitudinal guide hole 231b. At this time, the base end side position sensor S2 provided at the base end side end portion 235a of the longitudinal guide hole 231a of the left arm-shaped guide member 230a at the symmetrical position is used as the base end side end portion 235a of the roller 233a. As described above, the movable effect control circuit 320 controls the stop or inversion of the left and right movable decorative members 220a and 220b according to the control program. At this time, the movable decorative members 220a and 220b are in an open state (see FIG. 7).

  Here, the action of the coil spring 260 in a state where the movable decorative members 220a and 220b are opened will be described. In the state in which the movable decorative members 220a and 220b are opened, as shown in FIG. 8, the interval between the base end portions 251a and 251b of the left and right racks 250a and 250b is the minimum stroke interval L2, Longer than N. Therefore, the coil spring 260 is in an extended state and acts to pull back the distance between the base end portions 251a and 251b. Thus, the left rack 250a is always pushed toward the center side (left side in FIG. 8) of the support wall 210a, and the above-described backlash is absorbed.

  On the other hand, the coil spring 260 is also extended with respect to the right rack 250b as described above, and the right rack 250b is always pulled back to the center side (right side in FIG. 8) of the support wall 210a. The above-mentioned backlash is absorbed.

  Thus, in the state where the movable decorative members 220a and 220b are opened (see FIG. 7), the base end portions 251a and 251b of the left and right racks 250a and 250b are pulled back by the action of the coil spring 260. Correspondingly, the left and right movable decorative member bodies 221a and 221b correspondingly move away from each other by the action of the left and right racks 250a and 250b and the left and right longitudinal connecting members 270a and 270b. It is being spread out.

  At this time, when the movable decorative member 220a, 220b shifts from the closed state to the open state, and stops or reverses in the open state and shifts to the closed state again, Both-side movable decorative member main bodies 221a and 221b can exhibit uniform moving and stopping operations.

  As described above, also in the second embodiment, the movable effect device 200 closes the left and right movable decorative members 220a and 220b via the left and right meshing mechanisms GS1 and GS2 under the drive of the step motor 280. The production operation is repeated by moving between the state and the open state.

  As described above, the right and left side meshing mechanisms GS1 and GS2 include backlash generated due to mechanical assembly errors including backlash at a plurality of locations.

  Therefore, in the second embodiment, as described above, the coil spring 260 is sandwiched between the base end portions 251a and 251b of the left and right side racks 250a and 250b included in the left and right side meshing mechanisms GS1 and GS2. The coil spring 260 acts as an extension spring. That is, the natural length N of the coil spring 260 is shorter than the minimum stroke interval L2 between the base end portions 251a and 251b.

  Thus, the coil spring 260 always acts to pull back the distance between the left and right racks 250a and 250b while the left and right movable decorative members 220a and 220b repeat the movement between the closed state and the open state. That is, the left and right racks 250a and 250b move while receiving force in the direction of the central portion of the support wall 210a during the reciprocating operation.

  As a result, the play existing in the left and right side meshing mechanisms GS1 and GS2 is absorbed, and the movable decorative members 220a and 220b can perform uniform moving and stopping operations while repeating the opening and closing operations. In any case, the appearance of the effect by the movable effect device 200 can be ensured satisfactorily.
