  Further, as shown in FIG. 10, the lower pedestal B221 is provided with a plurality of screw holes 2214 for screwing the case B22. As the case B22, one having the same configuration as that of the first embodiment can be adopted. However, in this embodiment, as shown in FIG. 14, a case B22 having a rectangular parallelepiped box shape is adopted. Yes.

  Similarly to the first embodiment, the case B22 accommodates a lens unit B21 (see FIG. 9), an LED substrate, a DMD substrate, a heat sink, an intake fan, and the like, which are internal components of the projector device B2. A projector control board B23 (see FIG. 9) is fixed to the lower surface of the case B22.

  A lens unit cover B222 (see FIG. 9) is attached to the front opening B22k provided on the front surface of the case B22. The lens unit B21 is accommodated in the case B22 in a state where the projection lens 210 (see FIG. 9) is covered with the lens unit cover B222.

  Although not shown, the case B22 includes two intake fans 244A at a location on the left side of the center in the left-right direction (near the right end of the left side B221c in a state attached to the lower pedestal B221 (see FIG. 15)). -244B is arrange | positioned so that it may rank with front and back. A heat sink is provided on the left side of the two intake fans 244A and 244B.

  In addition, an intake port B22A is provided on the right side surface of the case B22 (see FIG. 14), and an exhaust port B22E is provided on the left side surface of the case B22 (see FIG. 15). As a result, in the case B22, a flow of air exhausted from the exhaust port B22E while forcibly taking in air from the intake port B22A by the intake fans 244A and 244B and taking heat away from the heat sink is formed.

  As shown in FIG. 15, the case B22 is attached to the lower pedestal B221 by screw fastening, and its upper end surface (upper wall portion B22F shown in FIG. 14) is the inner surface of the main body B221a of the lower pedestal B221. Abut. Further, in a state where the upper pedestal B220 and the lower pedestal B221 are connected, the main body B221a of the lower pedestal B221 is located above the upper pedestal B220. Accordingly, the upper wall portion B22F of the case B22 is also positioned above the upper pedestal B220.

  In this regard, in the first embodiment, the upper end of the case B22 is attached to the lower pedestal B221, and the upper pedestal B220 is disposed higher than that. For this reason, the case B22 cannot be disposed in the space formed between the upper pedestal B220 and the lower pedestal B221. On the other hand, in the present embodiment, an opening is formed in the upper base B220, and the upper end of the case B22 is disposed by placing the case B22 so that the upper end (upper wall portion B22F) of the case B22 passes through the opening. The (upper wall portion B22F) can be positioned above the upper base B220. Thereby, it is possible to effectively use the space for arranging the case B22.

  As described above, as compared with the first embodiment, the relative position of the case B22 (projector device B2) with respect to the upper pedestal B220 is moved upward, so that the front portion provided on the front surface of the case B22 is provided. A part of the upper pedestal B220 is arranged in front of the opening B22k (see FIG. 14) (see FIG. 15). That is, a part of the upper pedestal B220 is placed in front of the projection lens 210 (see FIG. 9) installed so as to correspond to the front opening B22k. Thereby, it seems that the light emitted from the projection lens 210 is blocked by the upper pedestal B220.

  However, the irradiation light is not blocked in this way. That is, in the present embodiment, the irradiation light is emitted from a portion below the optical axis of the projection lens 210. In other words, when the irradiation light is emitted, only the lower half of the projection lens 210 (the portion below the horizontal plane passing through the central portion in the vertical direction of the projection lens 210) is used. The light emission position of the projection lens 210 is different from that of a conventionally known projector (for example, see Japanese Patent Application Laid-Open No. 2008-058875).

  Thus, in the present embodiment, when the irradiation light is emitted, the upper half of the projection lens 210 is not used, and the irradiation light is emitted from a portion below the optical axis of the projection lens 210, as shown in FIG. Thus, the upper pedestal B <b> 220 arranged in front of the projection lens 210 exists above the optical axis of the projection lens 210. Therefore, the path of the light emitted from the projection lens 210 is lower than the upper pedestal B220, and the irradiation light is not blocked by the upper pedestal B220.

  Further, the lower pedestal B221 is bent downward to form the right side B221b, the left side B221c, and the rear end B221d, so that the right side B221b, the left side B221c, and the rear end B221d are respectively above. The upper pedestal B220 and the lower pedestal B221 can be connected so that the upper pedestal B220 is arranged. Thereby, the structure similar to 1st Embodiment is employable about the structure of three connection parts, changing the structure of upper side base B220 and lower side base B221 from 1st Embodiment.

  Therefore, the adjustment of the optical axis direction and the like of the light emitted from the projector device B2 can be performed by the same method as in the first embodiment. For such adjustment of the optical axis direction and the like, an advanced computer program is required, and development of the program requires a large amount of cost. In the present embodiment, the adjustment of the optical axis direction and the like can be performed using the same program as in the first embodiment, so that it is possible to suppress the generation of new costs.

  In the present embodiment, the case B22 is described as having the upper wall portion B22F. However, as in the first embodiment, the case B22 (see FIG. 9) with the upper side opened may be used. Good. Further, the method of attaching the case B22 to the lower pedestal B221 is not particularly limited, and the case B22 is attached to the lower pedestal B221 by using the stay B223a (see FIG. 9) as in the first embodiment. It is good as well.

  As described above, in this embodiment, by disposing a part of the case B22 above the upper pedestal B220, it is possible to move the case B22 upward compared to the first embodiment. A new space can be created in the lower region of the case B22. Such an effect is obtained by changing the configuration of the upper pedestal B220 from the first embodiment, and the projector cover B1 can adopt the same configuration as that of the first embodiment.

Although not shown, the exhaust port B22E (see FIG. 15) of the case B22 is also disposed so as to be close to the cavity B402 (the left cavity B402 of the two cavities B402).

  Accordingly, in the present embodiment, air is passed from the outside of the gaming machine 1 to the inside of the upper door mechanism UD through an opening formed on the upper surface wall of the upper door mechanism UD (the right opening of the two openings). Is adopted. The air moves downward in the upper door mechanism UD and is taken into the projector cover B1 through the opening B400 (right opening B400a) of the projector cover B1.

  The air that enters the projector cover B1 is above the duct cover B600 in the space P (the right space P of the two spaces P, see FIG. 24) formed by the projector cover B1 and the blind B500. After moving backward in the space P1 (see FIG. 27), the direction is changed to the inside of the projector cover B1, passing through the cavity B402 (the right cavity B402 of the two cavities B402), and the intake port B22A Enters the inside of the case B22.

  The air that has entered the inside of the case B22 proceeds to the left while taking heat generated in the case B22, and exits the case B22 through the exhaust port B22E.

  The air that has left the case B22 passes through the cavity B402 (the left cavity B402 of the two cavities B402), and then changes its path forward to the space P (the left space of the two spaces P). P) moves forward in the space P1 above the duct cover B650. Then, the air comes out of the projector cover B1 through the opening B400 (left opening B400b) of the projector cover B1.

  The air that has flowed out of the projector cover B1 moves upward inside the upper door mechanism UD, and then passes through an opening formed on the upper surface wall of the upper door mechanism UD (the left opening of the two openings). And released to the outside of the gaming machine 1.

  Of the air flow described above, the air flow path inside the projector cover B1 is indicated by a thick arrow in FIG. Further, the air flow in the space P1 is indicated by an arrow A in FIG. In the present embodiment, by forming such an air flow path, the heat generated in the projector device B2 can be discharged to the outside of the gaming machine 1.

  Here, as described above, the opening formed in the upper surface wall of the upper door mechanism UD exists immediately above the opening B400 (the right opening B400a and the left opening B400b) of the projector cover B1. That is, when the opening of the upper door mechanism UD and the opening B400 of the projector cover B1 are viewed from above, at least a part of them overlaps.

  Therefore, when foreign matter such as liquid enters the gaming machine 1 from the opening of the upper door mechanism UD, the foreign matter enters the projector cover B1. However, according to the present embodiment, even in such a case, it is possible to prevent the foreign matter from entering the case B22. Hereinafter, a case where the liquid L is introduced from the opening of the upper door mechanism UD will be described as an example.

  The liquid L introduced from the opening of the upper door mechanism UD passes through the opening B400 (right opening B400a) of the projector cover B1, and falls to the first horizontal portion B501 (see FIG. 22) of the blind B500.

  Here, as described with reference to FIG. 24, the upper end of the fifth wall portion B501e of the blind B500 and the lower end of the surface B402a (see FIG. 21) existing in front of the cavity B402 (see FIG. 18) of the projector cover B1. There is a certain gap between them, and the thickness of the duct cover B600 substantially matches the length of the gap. The duct cover B600 is disposed so as to contact both the upper end of the fifth wall portion B501e and the lower end of the surface B402a so as to fill the gap. Thereby, a gap corresponding to the height of the fifth wall portion B501e of the blind B500 is formed between the first horizontal portion B501 of the blind B500 and the duct cover B600. The liquid L passes through the gap and flows from the first horizontal part B501 toward the first inclined part B502a.

  Since the first inclined part B502a and the second inclined part B502c of the blind B500 have an inclination that descends toward the rear, the liquid L has the first inclined part B502a, the second horizontal part B502b, the second It flows backward through the inclined portion B502c and the third horizontal portion B502d. In this way, the liquid L flows on the surfaces of the first horizontal part B501, the first inclined part B502a, the second horizontal part B502b, the second inclined part B502c, and the third horizontal part B502d. Such a flow of the liquid L is indicated by an arrow L in FIG.

  The liquid L flowing backward collides with the rear wall portion B503 and is stored in a region surrounded by the rear wall portion B503, the outer wall portion B504, and the outer wall portion B507b (and the inner wall portion B505) (FIG. 28). reference). The region is included in a space P2 (see FIG. 27) below the duct cover B600 in the space P (see FIG. 24) formed by the projector cover B1 and the blind B500. For easy understanding, in FIG. 28, the stored liquid L is shown by shading.

  Here, the space P1 shown in FIG. 27 and the internal space Q (see FIG. 21) of the projector cover B1 are connected via an opening B510 shown in FIG. As shown in FIG. 28, the opening B510 has a shape in which the shape in a side view approximates a rectangle formed by the sides K to N.

  A side K constituting the lower end of the opening B510 corresponds to the upper end edge B505a (see FIG. 22) of the inner wall B505 of the blind B500. As shown in FIG. 22, the upper edge B505a of the inner wall portion B505 (the lower end of the opening 510) includes a first horizontal portion B501, a first inclined portion B502a, a second horizontal portion B502b, a second inclined portion B502c, and It is located above the third horizontal portion B502d (the path of the liquid L).

  Although not clearly shown in the drawing, the right end of the duct cover B600 is placed on the upper end edge of the outer wall portion B504 of the blind B500, and the left end of the duct cover B600 contacts the outer surface of the inner wall portion B505 of the blind B500. As a result, the main surface B610 (see FIG. 29) forms substantially the same plane as the upper end edge B505a of the inner wall portion B505 of the blind B500 (see FIG. 25). Thereby, the internal space Q of the projector cover B1 and the storage space (space P2) of the liquid L are separated by the duct cover B600, and the liquid L passes through the opening B510 and the internal space Q (inside the case B22) of the projector cover B1. ) Is less likely to occur.

Screw hole B650 is a hole for attaching duct cover B600 to projector cover B1 by screw fastening.

  The fan installation structure B620 includes a front engagement portion B621 that is erected at the front end of the main surface B610, a left rear engagement portion B622 that is erected from the main surface B610 behind the front engagement portion B621, and the right rear. A side engagement portion B623, and a lower engagement portion B624 that is slightly raised from the main surface B610 and extends in the front-rear direction (lower left engagement portion B624a, lower middle engagement portion B624b, and lower side Right engaging portion B624c).

  The lower left engagement portion B624a and the lower middle engagement portion B624b connect the back surface of the front engagement portion B621 and the front surface of the left rear engagement portion B622. The lower right engagement portion B624c connects the back surface of the front engagement portion B621 and the front surface of the right rear engagement portion B623.

  The upper end edge B621a of the front engagement portion B621, the upper end edge B622a of the left rear engagement portion B622, and the upper end edge B623a of the right rear engagement portion B623 are each formed in a curved shape. The opening vicinity fan B700 has a circular air passage B710. Upper end edge B621a, upper end edge B622a, and upper end edge B623a are formed in the shape (arc shape) corresponding to the shape of air passage part B710. In addition, in order to make it easy to understand, in FIG. 29, the upper end edge B621a and the upper end edge B622a are indicated by diagonal lines, and the air passage portion B710 is indicated by hatching.

  As shown in FIG. 30, a structure (fan installation structure) for installing the opening vicinity fan B700 is formed so as to protrude downward from the ceiling portion inside the projector cover B1. Specifically, the projector cover B1 includes a front engagement portion B421 formed along the rear end of the opening B400, a rear engagement portion B422 formed rearward of the front engagement portion B421, and a front-rear direction. And an upper engaging portion B423 (upper left engaging portion B423a, upper middle engaging portion B423b, and upper right engaging portion B423c) that extend.

  The upper engaging portion B423 connects the back surface of the front engaging portion B421 and the front surface of the rear engaging portion B422. The length of the downward protrusion from the ceiling portion inside the projector cover B1 is longer at the front engagement portion B421 and the rear engagement portion B422 than at the upper engagement portion B423.

  A lower end edge B421a of the front side engaging portion B421 and a lower end edge B422a of the rear side engaging portion B422 are each formed in a curved shape. The lower end edge B421a and the lower end edge B422a are formed in a shape (arc shape) corresponding to the shape of the air passage portion B710 of the opening vicinity fan B700. In addition, in order to make intelligible, in FIG. 30, the lower end edge B421a and the lower end edge B422a are shown with the oblique line.

  The opening vicinity fan B700 is sandwiched between the fan installation structure B620 of the duct cover B600 and the fan installation structure of the projector cover B1 described above.

  Specifically, the interval between the front engagement portion B621 and the left rear engagement portion B622 of the duct cover B600, the interval between the front engagement portion B621 and the right rear engagement portion B623, and the front engagement of the projector cover B1. The distance between the joint B421 and the rear engagement portion B422 is substantially equal to the length in the front-rear direction of the opening vicinity fan B700.

  Accordingly, the left front surface of the opening vicinity fan B700 is in contact with the back surface of the front side engaging portion B621 of the duct cover B600, and the left back surface of the opening vicinity fan B700 is connected to the left rear side engaging portion B622 of the duct cover B600. The opening vicinity fan B700 is in contact with the front surface, and is sandwiched between the front engaging portion B621 and the left rear engaging portion B622 of the duct cover B600. Further, the right front surface of the opening vicinity fan B700 is in contact with the back surface of the front engagement portion B621 of the duct cover B600, and the right rear surface of the opening vicinity fan B700 is the front surface of the right rear engagement portion B623 of the duct cover B600. The opening vicinity fan B700 is sandwiched between the front engagement portion B621 and the right rear engagement portion B623 of the duct cover B600.

  The front surface of the near-opening fan B700 is in contact with the back surface of the front engaging portion B421 of the projector cover B1, and the back surface of the near-opening fan B700 is in contact with the front surface of the rear engaging portion B422 of the projector cover B1. The opening vicinity fan B700 is sandwiched between the front engagement portion B421 and the rear engagement portion B422 of the projector cover B1.

  Further, the three lower engaging portions B624 (the lower left engaging portion B624a, the lower middle engaging portion B624b, and the lower right engaging portion B624c) of the duct cover B600 are directed upward from the main surface B610. The projecting lengths of are substantially equal to each other. Further, the three upper engagement portions B423 (upper left engagement portion B423a, upper middle engagement portion B423b, and upper right engagement portion B423c) of the projector cover B1 are downward from the ceiling portion inside the projector cover B1. The projecting lengths of are substantially equal to each other. The distance between the lower engaging portion B624 of the duct cover B600 and the upper engaging portion B423 of the projector cover B1 is substantially equal to the vertical length of the opening vicinity fan B700.

  Accordingly, the lower surface of the opening vicinity fan B700 is connected to the three lower engaging portions B624 (the lower left engaging portion B624a, the lower middle engaging portion B624b, and the lower right engaging portion B624c) of the duct cover B600. ) And the upper surface of the opening vicinity fan B700 has three upper engaging portions B423 (upper left engaging portion B423a, upper middle engaging portion B423b, and upper right engaging portion B423c) of the projector cover B1. ) And the opening vicinity fan B700 is sandwiched between the lower engagement portion B624 of the duct cover B600 and the upper engagement portion B423 of the projector cover B1.

  As described above, the opening vicinity fan B700 is fixed by being sandwiched between the duct cover B600 and the projector cover B1 from the front-rear direction and the vertical direction.

  In a state where the opening vicinity fan B700 is fixed, the front side peripheral edge of the air passage portion B710 is on the upper end edge B621a of the front engagement portion B621 in the duct cover B600 and the lower end edge B421a of the front engagement portion B421 in the projector cover B1. (See FIGS. 26 and 31). Further, although not shown, the rear side outer edge of the air passage portion B710 is in the upper end edge B622a of the left rear side engaging portion B622 in the duct cover B600, the upper end edge B623a of the right rear side engaging portion B623, and in the projector cover B1. It is positioned along the lower end edge B422a of the rear engagement portion B422.

  That is, the air passage portion B710 includes the front engagement portion B621, the left rear engagement portion B622, the right rear engagement portion B623 of the duct cover B600, and the front engagement portion of the projector cover B1 when viewed from the front. It does not overlap with B421 and the rear engagement portion B422. In other words, the air passage B710 includes the front engagement part B621, the left rear engagement part B622, the right rear engagement part B623 of the duct cover B600, and the front engagement part B421 of the projector cover B1. It is not covered with the rear engagement portion B422. Thereby, the area of the passage part of air can be ensured to the maximum extent.

  On the other hand, the peripheral edge of the air passage B710, the upper edge of the engaging part in the duct cover B600 (upper edge B621a, upper edge B622a, and upper edge B623a) and the lower edge of the engaging part in the projector cover B1 (lower edge) B421a and lower end edge B422a) are matched to increase the area of the portion where the near-opening fan B700 abuts on the duct cover B600 and the area of the portion where the near-opening fan B700 abuts on the projector cover B1. Accordingly, the opening vicinity fan B700 can be stably fixed.

  Further, as shown in FIG. 31, the front surface of the front engagement portion B421 in the projector cover B1 is a wall surface B401j (FIG. 16) formed downward from the rear end edge (side j shown in FIG. 17) of the right opening B400a. Match). Accordingly, the opening vicinity fan B700 is arranged behind the rear end edge (side j shown in FIG. 17) of the right opening B400a by the thickness in the front-rear direction of the front engagement portion B421. Accordingly, since the near-opening fan B700 exists at a position deeper than the right-opening B400a, even if liquid enters from the right-opening B400a of the projector cover B1, the liquid is unlikely to be directly applied to the near-opening fan B700. It is like that. On the other hand, since the opening vicinity fan B700 is disposed close to the right opening B400a, it is easy to take in air from the outside of the projector cover B1 via the right opening B400a. Thereby, the heat generated in the projector device B2 can be efficiently discharged.

  The left rear engagement portion B622 and the right rear engagement portion B623 of the duct cover B600 are configured separately, whereas the front engagement portion B621 is connected without the right and left parts being divided. It has a different shape. As a result, even if liquid enters from the right opening B400a of the projector cover B1, the liquid does not easily enter backward.

  Further, the length of the rear end edge (side j shown in FIG. 17) of the right opening B400a in the projector cover B1, the length in the left-right direction of the front side engaging portion B621 in the duct cover B600, and the left rear side engagement in the duct cover B600. The length from the left end of the portion B622 to the right end of the right rear engagement portion B623, the length in the left-right direction of the front engagement portion B421 in the projector cover B1, and the length in the left-right direction of the rear engagement portion B422 in the projector cover B1 And the length in the left-right direction of the opening vicinity fan B700 is substantially equal. As a result, an intermediate space from the right opening B400a of the projector cover B1 to the space P1 (see FIG. 27) (a cross section when the space P1 is cut by a vertical plane in the left-right direction) is substantially free from gaps by the opening vicinity fan B700. It is in a buried state. Also in this respect, the area of the air passage portion is ensured to the maximum, and the cooling efficiency of the projector device B2 can be increased.

<Storage and discharge of liquid>
FIG. 32 is a perspective view of the state in which the blinds and the duct cover are attached as seen from the left. FIG. 33 is a perspective view of the projector cover, the blind, and the duct cover as viewed from the rear. 34 is an exploded perspective view of the projector cover, the blind, and the duct cover shown in FIG. FIG. 35 is an exploded perspective view of the blind and the duct cover.

  FIG. 35 shows the blind B500 viewed from the front and above, while the duct cover B600 viewed from the rear and below.

  As described above, among the space P (see FIG. 24) formed by the projector cover B1 and the blind B500, the space P2 (see FIG. 27) below the duct cover B600 has entered the projector cover B1. Liquid can be stored (see FIG. 28).

  As described with reference to FIG. 22, the blind B500 includes the first horizontal portion B501, the first inclined portion B502a, the second horizontal portion B502b, the second inclined portion B502c, the third horizontal portion B502d, and the small room B507. Is formed. Accordingly, it is possible to secure a space for disposing the screen device C (see FIG. 5) below the blind B500 and to maintain the strength of the blind B500 while increasing the volume of liquid that can be stored. Yes.

  In particular, in the present embodiment, the presence of the small room B507 increases the strength of the blind B500, and the liquid can also be stored in the small room B507. That is, as described above, the notch 507c is formed in the small room B507, and when the liquid storage amount exceeds a certain amount, the liquid flows into the small room B507 from the notch 507c. In this way, by storing the liquid in the small room B507 provided as a rib, the space in the blind B500 is effectively utilized.

  As shown in FIG. 32, the duct cover B650 has a shape in which a left front corner portion in a rectangular shape in a top view is cut out. In order to make it easy to understand, in FIG. 32, the duct cover B650 is indicated by hatching. As described with reference to FIG. 25, the duct cover B600 is arranged along the front side wall B507a and the outer side wall B507b (see FIG. 22) of the small room B507 in a top view. In contrast, the duct cover B650 is shorter in the front-rear direction than the duct cover B600, and the rear end of the duct cover B650 is positioned in front of the small room B507.

  Of course, although not shown, the rear end of the duct cover B650 is from a surface B402b (see FIG. 21) existing behind the cavity B402 (see FIG. 18) of the projector cover B1, that is, from the side N of the opening B510 shown in FIG. Is also arranged rearward. Thereby, the duct cover B650 separates the internal space Q of the projector cover B1 from the storage space (space P2) of the liquid L, similarly to the duct cover B600, and the liquid L passes through the opening B510 and the projector cover B1. It is unlikely to enter the internal space Q (inside the case B22).

  Here, the liquid stored in the blind B500 is discharged using a discharge mechanism including a tube communicating from the blind B500 to the outside of the gaming machine 1. The tube is inserted into the blind B500 by inserting the liquid discharge hole S. Hereinafter, the liquid discharge hole S will be described.

  As shown in FIG. 33, the liquid discharge hole S is provided on the back side of the irradiation unit B. Specifically, as shown in FIGS. 34 and 35, the liquid discharge hole S is provided behind the wiring opening B411 of the projector cover B1, the wiring opening B510a and the wiring opening B511a of the blind B500, and the duct cover B600. Side part B630 (refer FIG. 29).

  The wiring opening B411 is formed as a notch whose bottom is open in the rear side wall portion B410 constituting the rear surface of the projector cover B1.

  The wiring opening B510a is formed as a notch that is open at the top in the first back side wall B510 that forms the back of the blind B500. The wiring opening B511a is formed as a notch that opens upward in the second back side wall part B511 formed in front of the first back side wall part B510 of the blind B500. The second back side wall B511 is formed so as to stand from the rear end of a horizontal plane B508 formed continuously from the upper end of the rear wall B503 toward the rear. The first back side wall part B510 is formed so as to stand up from the rear end of a horizontal plane B509 formed continuously from the lower end of the second back side wall part B511 toward the rear.

  The rear side portion B630 of the duct cover B600 includes a back side surface B631, and a downward projecting portion B632a and a downward projecting portion B632b projecting downward from both left and right edges of the surface B631. The downward protrusion B632a and the downward protrusion B632b face each other so as to be substantially parallel with a certain distance therebetween, and a space is formed between the downward protrusion B632a and the downward protrusion B632b. .

  When the projector cover B1, the blind B500, and the duct cover B600 are assembled, the wiring opening B411 of the projector cover B1, the wiring opening B510a and the wiring opening B511a of the blind B500, and the downward projecting portion of the duct cover B600 The space formed between B632a and the downward projecting portion B632b overlaps when viewed from the rear, and thereby, the liquid discharge hole S (the liquid discharge hole on the left side of the two liquid discharge holes S shown in FIG. 33). Hole S) is formed. The duct cover B650 is not formed with the rear side portion B630 (see FIG. 32), and therefore the right liquid discharge hole S of the two liquid discharge holes S shown in FIG. 33 is the projector cover B1. The wiring opening B411 and the wiring opening B510a and the wiring opening B511a of the blind B500 are formed.

  A tube for discharging the liquid stored in the blind B500 is inserted into the liquid discharge hole S, and various functional parts (sub-control device SS, etc.) other than the irradiation unit B are connected to the projector device B2, etc. Wiring for doing this is also inserted. The wiring is connected to the projector device B2 and the fan near opening B700 by inserting the wiring openings B640a and B640b (see FIG. 29).

  Here, the wiring openings B640a and B640b are formed outside the duct cover B600 (near the right end), and the wiring openings B640a and B640b are formed in the internal space Q (see FIG. 21) of the projector cover B1. The position is away from the opening B510 (see FIG. 28) that is open to the front. This makes it difficult for the liquid stored in the blind B500 to enter the internal space Q (inside the case B22) of the projector cover B1 via the wiring openings B640a and B640b.

  As above, the gaming machine 1 according to the second embodiment has been described as one embodiment of the present invention.

The liquid flows through the inclined portion (inclined portion B502) so as to descend as it moves away from the portion immediately below the first opening (right opening B400). Here, since at least a part of the inclined portion (inclined portion B502) is located below the lower end (upper edge B505a of the inner wall portion B505) of the third opening (right opening B510), the liquid is inclined. The lower part of the third opening (right opening B510) and lower than the lower end (upper edge B505a of the inner wall part B505) of the third opening (right side opening B510). Since the lower end (the upper end edge B505a of the inner wall portion B505) of the opening B510) is present at the upper side, the liquid does not easily pass through the third opening (the right-side opening B510), and the liquid does not pass through the projector. It is difficult for the projector device B2 to enter the place where the projector device B2 is disposed. In this way, according to the gaming machine 1 according to the modified example, it is possible to protect the projector (projector apparatus B2) from foreign matters such as liquid entering from the outside of the gaming machine.

(I-2) The gaming machine of (I-1),
On the upper surface of the main body (the upper wall G4 of the cabinet G), there is a fifth opening (the right opening G41 of the two openings G41) above each of the first opening and the second opening. ) And the sixth opening (the left opening G41 of the two openings G41),
It is characterized by that.

  According to the gaming machine 1 according to the modification, the first opening (right opening B400) and the second opening of the cover member (projector cover B1) are formed on the upper surface (upper wall G4) of the main body (cabinet G). A fifth opening (right opening G41) and a sixth opening (left opening G41) are formed above each opening (left opening B400). As a result, air is introduced into the gaming machine from above the gaming machine via the fifth opening (right opening G41) of the main body (cabinet G), and the first opening of the cover member (projector cover B1). After this air has flowed into the cover member (projector cover B1) through the right opening B400, the air that has passed through the projector (projector apparatus B2) is passed through the second member of the cover member (projector cover B1). Through the opening (left opening B400) and the sixth opening (left opening G41) of the main body (cabinet G), it can be discharged to the outside of the gaming machine. As described above, in the gaming machine 1 according to the above-described modification, the discharge destination of the air that has passed through the projector (projector apparatus B2) is located above the outside of the gaming machine. If it is discharged from the back of the game, there is a concern that heat will be accumulated in the island facilities installed in the game store, which will adversely affect the control of the game machine. If air is discharged from the side of the gaming machine, the warmed air will be taken into the adjacent gaming machine, resulting in a vicious cycle of warm air between the adjacent gaming machines. It is considered that the cooling efficiency of (projector apparatus B2) cannot be increased. Furthermore, if air is exhausted in front of the gaming machine, hot air may be blown to the player's face. In this regard, according to the gaming machine 1 according to the modified example, it is possible to create an air flow for releasing heat generated in the projector (projector apparatus B2) without causing such a problem.

  On the other hand, according to the gaming machine 1 according to the modified example, the fifth opening (the right opening G41) and the sixth opening (the left opening) formed in the upper surface of the main body (the upper wall G4 of the cabinet G). G41) exists above the first opening (right opening B400) and the second opening (left opening B400) formed in the cover member (projector cover B1). If a foreign object enters the inside of the gaming machine from the outside through the right opening G41) or the sixth opening (left opening G41), the foreign object is transferred to the first opening (right opening B400) or the second opening. It is easy to enter the inside of the cover member (projector cover B1 and blind B500) through the opening (left opening B400). For this reason, there is a concern that foreign matter that has entered the cover members (projector cover B1 and blind B500) reaches the projector (projector apparatus B2) and adversely affects the projector (projector apparatus B2). For example, when a player injects a drink from the fifth opening (right opening G41), the drink passes through the first space (right space P) and the third opening (right opening B510). If the projector enters the projector (projector apparatus B2), the projector (projector apparatus B2) may break down. In this regard, according to the gaming machine 1 according to the above-described modified example, the cover member (projector cover B1) from the outside of the gaming machine via the fifth opening (right opening G41) and the first opening (right opening B400). Even if the liquid enters the inside of the blind B500), the liquid flows along the inclined portion (inclined portion B502) as described above, so that such a situation occurs. Can be prevented.

  As shown in FIG. 40, a screen device C (see FIG. 5) is arranged on the back side of the game board 6114. Thereby, similarly to the above-described embodiment, the light emitted from the projector device B2 of the irradiation unit B is irradiated onto the screen (the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1) of the screen device C. Be able to.

  The decoration unit 6258 is attached to the upper part of the frame member 6211 (see FIG. 41). Although not shown, the frame member 6211 is fixed to the back side of the glass door 6111.

  As shown in FIG. 41, the irradiation unit B is attached to the upper part of the frame member 6211. By attaching the decoration unit 6258 to the frame member 6211 in a state where the irradiation unit B is attached to the frame member 6211, the irradiation unit B is accommodated in the internal space of the decoration unit 6258.

  In addition, a speaker 6152 and a speaker holder 6152A are integrally attached to the upper part of the frame member 6211 on both the left and right sides of the irradiation unit B. On the other hand, the decoration unit 6258 is provided with speaker holes 6151A and 6151B on the right side and the left side, respectively. The speaker holes 6151A and 6151B are formed as mesh-shaped openings.

The pachinko gaming machine 6100 can be discharged to the outside.

  Here, the speaker hole 6151A also functions as a vent for taking in air from the outside of the pachinko gaming machine 6100. As shown in FIG. 41, an intake fan 6244 is disposed on the front right side of the irradiation unit B. Thereby, air is taken into the interior of the pachinko gaming machine 6100 from the outside of the pachinko gaming machine 6100 through the speaker hole 6151A.

  Similar to the second embodiment, this air is taken into the projector cover B1 through the opening B400R of the projector cover B1 (the right opening B400 of the two openings B400) and is generated in the projector device B2. The heat travels through the projector cover B1 while taking the heat, and goes out of the projector cover B1 through the opening B400L (the left opening B400 of the two openings B400).

  The air that has come out of the projector cover B1 passes through the through-hole 6245 formed in the frame member 6211, moves backward, and is released to the outside from the back side of the pachinko gaming machine 6100.

  The air flow described above is indicated by arrows in FIGS. 39 and 41. In 2nd Embodiment, the case where air was taken in from the exterior upper direction of the game machine 1 and air was discharged | emitted to the exterior upper direction of the game machine 1 was demonstrated. On the other hand, in this modification, air is taken in from the outside front of the pachinko gaming machine 6100, and the air is discharged to the outside rear of the pachinko gaming machine 6100. As described above, in the present invention, the direction in which the air for cooling the projector is taken in and the direction in which it is discharged are not particularly limited, and can be appropriately designed according to the arrangement position of the projector, the structure around the projector, and the like.

  Note that pachinko gaming machines have a shorter depth in the front-rear direction of the gaming machine compared to pachislot gaming machines, so when another pachinko gaming machine is installed on the back side of one pachinko gaming machine on the same island facility A relatively large space exists between these pachinko machines. Therefore, even if the air warmed by the projector is discharged from the back of the pachinko gaming machine, it is considered that the island facility of the pachinko gaming machine does not accumulate heat as much as the island facility of the pachislot gaming machine.

  Hereinafter, as another modified example, a case where air is taken in from the outside right side of the pachinko gaming machine 6100 and discharged to the outside left side of the pachinko gaming machine 6100 will be described with reference to FIG. FIG. 42 is a perspective view showing the appearance of a pachinko gaming machine.

  As shown in FIG. 42, an opening 6300R is formed on the right side surface of the decoration unit 6258. Thereby, air is taken into the interior of the pachinko gaming machine 6100 from the outside right side of the pachinko gaming machine 6100 through the opening 6300R.

  This air is taken into the projector cover B1 through the opening B400R (the right opening B400 of the two openings B400) of the projector cover B1 and is generated in the projector device B2, as in the above-described modification. The heat travels through the projector cover B1 while taking the heat, and goes out of the projector cover B1 through the opening B400L (the left opening B400 of the two openings B400).

  Although not shown in the drawing, an opening (opening 6300L) is formed on the left side surface of the decoration unit 6258 as well as the right side surface. Thereby, the air that has flowed out of the projector cover B1 from the opening B400L is discharged from the opening 6300L to the outside of the pachinko gaming machine 6100.

  Such air flow is indicated by arrows in FIG. In this modification, it is considered that the warmed air may be taken into the adjacent gaming machine because the air discharge direction is set to the side of the gaming machine. In order to prevent the occurrence of such a situation, when the air discharge direction is set to the side of the gaming machine, for example, the width of the decoration unit 6258 in the left-right direction is further shortened, for example, It is desirable that the exhaust port (opening 6300L) in the gaming machine and the intake port (opening 6300R) in the pachinko gaming machine installed next to the pachinko gaming machine be separated to some extent.

  Hereinafter, another modification will be described with reference to FIG. FIG. 43 is an exploded perspective view of the pachinko gaming machine.

  In the modification mentioned above, it demonstrated as the irradiation unit B being attached to the frame member 6211. FIG. In contrast, in the example shown in FIG. 43, the irradiation unit B is attached to the base door 6113. A speaker 6152 is also attached to the base door 6113. Also in such a modification, the air flow path similar to the example mentioned above can be formed.

  FIG. 43 shows a state where the irradiation unit B is attached to the front side of the base door 6113, but the irradiation unit B may be attached to the rear side of the base door 6113. In the present invention, the irradiation unit B may be installed in front of the game board, or may be installed in the rear of the game board. When the irradiation unit B is installed behind the game board, the irradiation unit B can be disposed by using the space while forming a space on the back side of the game board.

  For example, an opening unit is provided in the center of the game board, and the irradiation unit is arranged on the base door, the game board, or other rear members of the pachinko gaming machine so that the front part of the irradiation unit penetrates the opening part. Also good. In that case, a conventional pachinko gaming machine (a pachinko gaming machine having a configuration in which an opening is provided in the center of the gaming board and a liquid crystal display device or the like behind the gaming board is visible through the opening). Can be diverted as it is. For example, by removing the liquid crystal display device, arranging the screen mechanism, and further arranging the irradiation unit on the rear member of the game board, etc., the irradiation unit and the screen mechanism are mounted while the shape of the game board remains the same. It becomes possible to make it a new gaming machine. When adopting such a configuration, a part of the front of the irradiation unit protrudes forward of the game board, so that a larger space behind the pachinko gaming machine can be secured. By doing so, when a pachinko gaming machine with an irradiation unit is installed in the entire island facility in a narrow game facility with island facilities, it is possible to reduce the temperature rise in the island facility. Further, a small-sized liquid crystal display device in which a decorative member such as a logo corresponding to the model is arranged in front of the irradiation unit (for example, around the reflector holding portion B11) that can be visually recognized by the player, or for auxiliary decoration. By arranging an electric decoration board or the like, the irradiation unit can be blinded so as not to be seen by the player, and the effect can be further enhanced.

  The screen device C may be installed in a state of being attached to the irradiation unit B, or may be installed in a state of being separated from the irradiation unit B.

  In the modification described above, the air discharge direction is the rear or side of the gaming machine, but air may be discharged from above the gaming machine as in the second embodiment. When the air discharge direction is upward, for example, an exhaust opening may be formed on the upper surface of the decoration unit 6258 (glass door 6111). In this case, when the irradiation unit B is installed behind the game board, an opening may be appropriately formed in the game board in order to secure an air passage.

  In the present invention, it is possible to appropriately form openings in the members existing on the air flow path according to the direction in which air is introduced and discharged, and the path through which air flows. A tubular duct may be provided according to the air flow path.

  Further, in order to make the air flow smooth, an intake fan and / or an exhaust fan can be provided as appropriate. For example, an intake fan (for example, the intake fan 6244 in FIG. 41) is disposed between the opening for taking in air (for example, the opening 6300R in FIG. 42) and the opening B400R in the projector cover B1, or air is supplied. It is possible to dispose an exhaust fan between the discharge opening (for example, the opening 6300L in FIG. 42) and the opening B400L of the projector cover B1. However, as long as intake and exhaust are sufficiently performed by the fan provided inside the irradiation unit B, it is not necessary to dispose the fan outside the irradiation unit B.

  In the above-described modification, the projector cover B1 described in FIG. 37 is used, but the configuration of the projector cover is not particularly limited, and an opening for taking in cooling air for the projector, In addition, a projector cover in which an opening for discharging the air is formed can be used as appropriate. These openings can be formed at any location such as the front, rear, upper, lower, side, etc. of the projector cover, and the positions where the openings are formed are appropriately determined in consideration of the cooling efficiency of the projector. be able to. Further, the projector may be disposed inside the gaming machine in an exposed state without being covered by the projector cover, and the cooling air taken from the outside of the gaming machine is directly input to the projector (via the projector cover). It is also possible to configure it to hit (without).

  The first embodiment and the second embodiment have been described above. In the embodiment described above, the case where the present invention is applied to a pachislot gaming machine has been described, but the present invention can also be applied to other gaming machines (for example, pachinko gaming machines, slot machines, etc.).
