  In order to prevent such destruction of the speaker 9, the slot machine 1 according to the embodiment of the present invention includes a protection plate 97 in the speaker mounting portion. Although this protective plate 97 does not have a hole, it has a function of covering the front side of the speaker 9 so that the front side of the speaker 9 is not directly visible while forming a bent audio output path S. It is designed to prevent the intrusion of unauthorized tools that go straight ahead.

More specifically, the protection plate 97 of the present embodiment includes two plate-like members 97a and 97b that are alternately stacked on the front side of the speaker 9 while being shifted in the vertical direction.
The two plate-like members 97 a and 97 b are formed of a flat plate-like member without having many sound output holes 96 as formed in the speaker grill 95.

One plate-like member 97a utilizes a part of the front door 1a and is formed in a fan shape that covers the upper half of the opening 91 that is originally circular.
Specifically, as shown in FIGS. 4 and 5, the plate-like member 97 a is disposed at a position facing the speaker 9 at a distance D1 (for example, 3 mm) from the speaker 9, and the opening 91 of the speaker 9 is located above the opening 91. It is formed to cover more than half.
By arranging in this manner, an output path with a distance D1 is secured in a side view of the speaker 9 viewed from the side, and an angle α (for example, 150) in the lower half in the front view of the speaker 9 viewed from the front. Degree of opening 91 is secured. That is, it is possible to reduce the intrusion area of the unauthorized tool that goes straight toward the front of the speaker 9 as much as possible while securing the sound output path without blocking the opening 91 of the speaker 9.
Further, the plate-like member 97a is formed with a screw fixing portion 97a-1 for fixing the plate-like member 97b using a screw 99. The screw fixing portion 97a-1 is formed in the vicinity of the lower end portion that is a portion that crosses the front surface of the speaker 9 of the plate member 97a.

The other plate-like member 97 b is made of a fan-shaped steel plate and is formed so as to cover the lower half of the opening 91.
Specifically, as shown in FIGS. 4 and 5, the plate-like member 97b is arranged in parallel with the plate-like member 97a at a position facing the player side with a gap D2 (for example, 5 mm). The lower half of the opening 91 is covered so as to complement the region not covered with 97a.

The plate-like member 97b is fixed at a plurality of locations. Specifically, the plate-like member 97b is fixed to the plate-like member 97a via the protruding piece 98 standing in front of the opening 91 and the screw fixing portion 97a-1. It is fixed using screws 99.
Therefore, the plate-like member 97b has a screw hole 97b-1 for fixing to the plate-like member 97a at a position shifted from the center of the speaker 9, and a screw hole 97b-2 for fixing to the projecting piece 98, Two holes 97b-3 for positioning when fixing to the projecting piece 98 are formed.
The plate-like member 97b is fixed to the screw fixing portion 97a-1 via the screw hole 97b-1, and is fixed to the screw fixing portion 98a formed on the protruding piece 98 via the screw hole 97b-2. Further, the plate-like member 97b is fitted to the convex portion 98b formed on the protruding piece 98 through the hole 97b-3, and is positioned with respect to the protruding piece 98.
In addition, the screw hole 97b-1 is formed in the upper end part vicinity which is a part which crosses the speaker 9 front surface of the plate-shaped member 97b.

  As shown in FIG. 5, the protection plate 97 configured as described above is configured such that one plate-like member 97 a is spaced from the speaker 9 by a distance D <b> 1 (for example, 3 mm) when the speaker 9 is viewed from the side. 9 and the other plate-like member 97b covers the lower front side of the speaker 9 with a distance D2 (for example, 5 mm) from the plate-like member 97a, so that a bent audio output path S is formed. On the other hand, the front side of the speaker 9 is covered so that it cannot be seen directly, and the intrusion of an unauthorized tool that goes straight toward the front of the speaker 9 can be prevented.

Furthermore, as shown in FIG. 4, the protection plate 97 has a lower end portion of one plate-like member 97a and an upper end portion of the other plate-like member 97b which are different from each other in a front view when the speaker 9 is viewed from the front. Overlapping portions W that form overlapping areas (shaded areas in the figure) are formed.
The overlapping portion W is formed to have a predetermined width (for example, 20 mm) so as to substantially cross the front surface of the speaker 9. Thereby, in the output path S, a U-shaped path (turnback) with a small curvature is formed over the front surface of the speaker 9, so that the intrusion path of the unauthorized tool becomes a maze.

  That is, by forming the overlapping portion W, at least one U-shaped path (folding) is formed in the output path S, and the output path S including such a U-shaped path is a front surface of the speaker grill 95. Since the intrusion path of the unauthorized tool from the side to the front of the speaker 9 is configured in a maze shape, it is possible to make the intrusion of the unauthorized tool more difficult and to reliably prevent the destruction of the speaker 9 by the unauthorized tool. In addition, since the overlapping portion W is formed so as to substantially cross the front surface of the speaker 9, a U-shaped path is formed in every part in the front view.

When the speaker 9 is built in the rear surface side of the storage tray 81 as in the present embodiment, the protective plate 97 is configured such that the terminal end opening K of the output path S faces upward as shown in FIG. It is.
This is because the plate-like member 97b arranged at the position facing the player side is formed so as to cover the lower half of the opening 91, so that the terminal end opening K of the output path S faces upward.
Since not only the slot machine but also the pachinko machine, the storage tray 81 is generally installed at the lowermost part of the gaming machine, so that the end opening K of the output path S is directed upward so that it is built in the rear side. The sound output from the speaker 9 can be delivered to the player's ear.

Furthermore, the terminal end opening K is formed so as to be positioned above the maximum storage height L of the medals when the medals are stored most in the storage tray 81 (for example, the front end height of the storage tray). .
In this way, even when many medals are accumulated in the storage tray 81, the end opening K is prevented from being blocked by medals, and the sound generated by the speaker 9 is reliably output to the player. Can do.

As shown in FIG. 6, the plate-like member 97b is fixed to the projecting piece 98 and the plate-like member 97a.
That is, the plate-like member 97b is fixed to the screw fixing portion 97a-1 via the screw hole 97b-1, and is fixed to the screw fixing portion 98a formed on the protruding piece 98 via the screw hole 97b-2. . By fixing the plate-like member 97b in the plurality of fixing portions in this way, it is possible to prevent the vibration caused by the vibration of the plate-like member 97b generated by the sound pressure of the speaker 9.

In particular, the upper end portion side of the plate-like member 97b that crosses the front surface of the speaker 9 is the free end side when the plate-like member 97b is regarded as a cantilever (the protruding piece 98 side is the support side). ), And the upper end side receives the sound pressure of the speaker 9 and vibrates like a tuning fork. Therefore, by fixing the vicinity of the upper end (screw hole 97b-1), vibration of this portion can be suppressed.
Also, for one plate-like member 97a, this portion (near the lower end portion) is also on the free end side, so that it is fixed to the plate-like member 97b via the screw fixing portion 97a-1, The vibration of this part can be suppressed. That is, by fixing the end portions (overlapping portion W) crossing the front surface of the speaker 9 in the plate-like members 97a and 97b, it is possible to suppress the end side from vibrating as a free end, and to prevent vibration caused by the vibration of the protective plate 97. Can prevent sticking.

  According to the present embodiment configured as described above, in the slot machine 1 including the speaker 9 that outputs sound, a plate-like member having no hole, while forming the bent sound output path S, A protective plate 97 that covers the front side of the speaker 9 so as not to be directly visible is provided, and this protective plate 97 prevents the intrusion of an unauthorized tool that goes straight toward the front of the speaker 9, thereby preventing the speaker 9 from being damaged by the unauthorized device. can do.

Further, since the protection plate 97 of the present embodiment is composed of a plurality of plate-like members 97a and 97b formed alternately on the front side of the speaker 9, it is as simple as adding a plurality of plate-like members 97a and 97b. It can be implemented at low cost by a simple configuration change.
In addition, since the one plate-like member 97a of the present embodiment is formed by using a part of the front door 1a, the number of parts can be reduced and it can be implemented at a lower cost.

The gaming machine of the present invention has been described with reference to the preferred embodiment, but the gaming machine according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. It goes without saying that it is possible.
For example, in this embodiment, the number of plate-like members that are alternately (alternately) overlapped with each other at a predetermined interval is two, and an output path bent in a U-shape is formed by these two plate-like members. However, the number of plate-like members may be three or more to form a more complicated unauthorized tool output path (illegal tool intrusion path). In this case, the overlapping portions W can be overlapped so as to have different widths.

  Further, in the present embodiment, the two plate-like members are formed so as to be overlapped while being shifted in the vertical direction, so that the overlapping portion W is formed so as to cross the front of the speaker 9. The overlapping portion W can also be formed so as to cut the front surface of the speaker 9. In addition, by overlapping a plurality of plate-like members, a plurality of overlapping portions W that cross in the transverse direction and longitudinal direction and in an arbitrary direction can be formed, and a more complicated intrusion path for unauthorized tools can be formed.

  In this embodiment, the plate-like member 97a facing the speaker 9 is formed so as to cover more than half of the opening 91 of the speaker 9. However, as shown in FIG. = About 180 degrees) can be secured. Further, as shown in FIG. 7B, the covering can be performed so as to ensure more than half of the opening 91 (for example, the angle α = about 210 degrees). Thereby, while ensuring the maximum audio output range from the speaker 9, it is possible to cover the front side of the speaker 9 so that it cannot be viewed directly, and to prevent intrusion of unauthorized tools that go straight toward the front of the speaker 9.

  Moreover, in this embodiment, although the protective plate was comprised by the several plate-shaped member, it can also be comprised by one plate-shaped member. In this case, one plate-like member is folded in a superimposed manner along the front direction of the speaker 9, and the bent portion is opened to form an audio output path S, and the bent plate-like member is formed. A protection plate that covers the front side of the speaker 9 with a member so as not to be directly visible can also be configured.

  INDUSTRIAL APPLICABILITY The present invention can be used in a pachinko machine, a slot machine, an arrangement ball, a sparrow ball, and other gaming machines equipped with a speaker that outputs sound, and in particular, can reliably prevent destruction of the speaker by an unauthorized tool such as a wire Can be suitably used for gaming machines that require
