  By the way, in the shutter device described in Patent Document 1, since the display area is closed in a state where the inclined surfaces of the shielding plates overlap with each other, there is no gap between the shielding plates, so that the lower limit sensor that detects the fully closed state has high detection. Accuracy is not required. However, for example, when the sensor is applied to an effect display device having a plurality of double-spreading shielding plates (opening / closing plates), the sensor accurately detects the fully closed state of the open / close plates that are closed without overlapping. Since it cannot be performed, the display content of the display unit may leak from a slight gap between the opening and closing plates.

  The present invention has been made in view of the above points. For example, even when the display unit is closed with a double-folded opening and closing plate, the display content of the display unit is prevented from leaking from between the opening and closing plates when closed. An object is to provide an effect display device and a gaming machine capable of improving the effect.

  The effect display device of the present invention includes a display unit for effect display, an opening / closing mechanism having a plurality of opening / closing plates capable of opening and closing the front surface of the display unit, a drive control unit for opening / closing the plurality of opening / closing plates, A plurality of positioning portions for positioning the respective closed positions of the plurality of opening / closing plates; and a detection portion for detecting the blocking of the plurality of opening / closing plates, wherein the drive control unit is configured to detect the opening / closing plates of the opening / closing plates. When closing is detected, the opening / closing plate is driven in the closing direction to contact the positioning portion.

  According to this configuration, when the drive control unit closes the opening and closing plate and the detection unit detects the closing of the opening and closing plate, the opening and closing plate is further driven in the closing direction to contact the positioning unit that positions the closing position. Even without using a detection sensor having high detection accuracy, it is possible to prevent the display contents of the display unit from leaking from the gap between the open / close plates due to the plurality of open / close plates closing the front surface of the display unit. Therefore, the display part is completely closed during non-production display, and the display part is opened only during presentation display, so that the production effect can be improved.

  In the effect display device of the present invention, the drive control unit drives the opening / closing plate in the closing direction further than a driving amount required to drive the opening / closing plate from the open position to the closing position.

  According to this configuration, the opening / closing plate is driven further in the closing direction than the driving amount required to drive the opening / closing plate from the open position to the closing position. Can be completely occluded.

  In the effect display device of the present invention, the plurality of opening / closing plates are arranged without overlapping each other so that the front surfaces of the opening / closing plates form the same plane in the closed state.

  First, the case where the opening / closing unit 12 and the display unit 13 are moved forward and backward in conjunction with each other will be described. When a drive instruction is received from the drive control circuit 81, the drive motors 88 and 92 are driven, and the drive force is transmitted to the gear trains 87 and 91 via the drive shafts 86 and 90, respectively. The driving force is transmitted to the rack gears 20 and 21 that mesh with the pinion gears 89 and 93 on the output end side of the gear trains 87 and 91, respectively, and the opening / closing unit 12 and the display unit 13 move forward.

Therefore, the display unit 13 moves forward in a state where the position is restricted in the vertical direction and the width direction. Therefore, it is possible to prevent the play caused by the forward / backward movement of the display unit 13 and to prevent interference between the display unit 13 and the opening / closing unit 12 even when the display unit 13 passes through the support frame 45. it can.

  When the display unit 13 moves 67.5 mm (500 steps) by the driving force of the drive motor 92, the detection sensor 96 detects the passage of the display unit 13 and sends a detection signal to the drive control circuit 81. In response to the drive signal of the drive control circuit 81 that has received the detection signal, the drive motor 92 further moves the display unit 13 from the detection start position of the detection sensor 96 by 1 mm (7 steps). Then, the display unit 13 passes through the support frame 45, and an effect corresponding to the gaming state is displayed on the display display 43.

  Next, the opening / closing control operation of the opening / closing unit 12 according to the present embodiment will be described with reference to FIGS. FIG. 9 is a diagram schematically illustrating a positional relationship between the opening / closing plate and the detection sensor of the opening / closing unit according to the comparative example. FIG. 10 is a diagram schematically showing the positional relationship between the opening / closing plate and the detection sensor of the opening / closing unit according to the present embodiment.

Then, as shown in FIG. 11A, the opening / closing plate 202 moves in the opening direction by 19 steps from the detection position of the detection sensor 201. On the other hand, when closing the opening / closing plate 202 from the open state, when the opening / closing drive motor 204 is driven, the opening / closing plate 202 moves by 439 steps in the closing direction. As described above, in the comparative example, since the closing operation is performed based on the open state of the opening / closing plate 202, when the opening position is displaced due to its own weight or the like, the opening / closing plate 202 is completely closed. It may not be possible.

  On the other hand, in the present embodiment shown in FIG. 10, the detection sensor 60 is configured to detect the closed state of the opening / closing plate 61. When the opening / closing plate 61 is opened from the closed state shown in FIG. 10B, when the opening / closing drive motor 56 is driven in response to a drive signal from the opening / closing control circuit 59, the opening / closing plate 61 is opened in the opening direction. Then, as shown in FIG. 11 (b), from the position where the detection sensor 60 no longer detects the shielding plate 68, the upper opening / closing plate 61 moves in the opening direction by 399 steps, and the lower and left and right opening / closing plates are opened. 61 moves 396 steps in the opening direction. Here, the driving amount of the upper opening / closing plate 61 is set to be larger than the driving amounts of the other opening / closing plates 61 in consideration of gear backlash loss (gap, etc.). At this time, the opening angle is 88 degrees from the closed position (84 degrees from the detection position of the detection sensor 60). On the other hand, when the opening / closing plate 61 shown in FIG. 10A is closed from the open state, when the opening / closing drive motor 56 is driven, the opening / closing plate 61 moves in the closing direction, and the detection sensor 60 detects the shielding plate 68. The clamping and fixing portion 79 that clamps the opening / closing plate 61 contacts the front surface of the protruding portion 64 c of the fixing portion 64. Then, from this detection position, the opening / closing plate 61 is moved in the closing direction by 42 steps. As described above, in the present embodiment, the closing operation is performed based on the closing state of the opening / closing plate 61, and the driving amount from the normal opening position to the closing position is increased. Even when a deviation occurs in the open position, the display unit 13 can be reliably closed by driving the opening / closing plate 61 in the closing direction.

  Next, a method for fixing the opening / closing unit 12 and the display unit 13 to the housing 11 will be described with reference to FIG. FIG. 12 is a schematic cross-sectional view for explaining a method of fixing the opening / closing unit 12 and the display unit 13 to the housing 11.
