It has become.

  The number of the light source openings 31c is not particularly limited, but in the push button unit for a gaming machine according to the present embodiment, one light source opening 31c is provided on the side peripheral wall portion of each holding portion 31. The side peripheral wall portion of the holding portion 31 has a structure that is closed except for the portion where the light source opening 31c is provided, and reduces the number of places that can be a clue to fraud. Further, by providing the light source opening 31 c in the side peripheral wall portion instead of the bottom portion of the holding portion 31, it is assumed that the outer peripheral surface of the peripheral wall portion 12 b in the pushbutton lid 12 and the inner periphery of the assembly opening 21 in the front cover 20. Even if a wire (not shown) is inserted from the gap with the surface, the wire is difficult to reach the light source opening 31c, and the front side of the front cover 20 is illegally accessed from the rear side of the rear holder 30. It has become difficult. The above-described engagement opening 31a, sensor opening 31b, and the like may be provided on the side peripheral wall portion instead of the bottom portion of the holding portion 31.

  The method for fixing the rear holder 30 to the front cover 20 is not particularly limited. As shown in FIG. 6, by screwing a screw 60 from the rear of the rear holder 30, the rear holder 30 and the front cover 20 Are preferably fixed to each other. Thereby, it becomes possible to make it impossible to remove the rear cover 30 from the front side of the front cover 20 (outside the casing of the gaming machine). In other words, not only the fixing part is hidden from the front side of the front cover 20 so that the fixing part of the rear holder 30 cannot be accessed, but also the part exposed to the outside of the gaming machine housing (the front cover 20 and the gaming machine). It is possible to prevent the fixed portion of the rear holder 30 from being easily removed even when the push button 10 or the like is hit or shaken.

[Operation of push button retaining part]
As described above, the push button unit for gaming machines of this embodiment has the push button retaining portion 10c formed on the push button 10 for gaming machines. As shown in FIG. 5, the outer diameter D of the push button retaining portion 10 c is larger than the inner diameter d of the assembly opening 21 of the front cover 20. For this reason, the push button 10 for gaming machines cannot be pulled out from the outside of the casing of the gaming machine (the front side of the front cover 20). That is, as shown in FIG. 5, when the push button 10 for gaming machine assembled to the front cover 20 is pulled out from the front side of the front cover 20, the push button retaining portion 10c passes through the assembly opening 21. Instead, it is caught on the back side of the front cover 20.

  Further, the push button retaining portion 10c is provided continuously over the entire peripheral portion of the outer peripheral portion of the push button 10 for gaming machines. For this reason, for the purpose of fraud, a wire (not shown) or the like from the gap between the outer peripheral surface of the pushbutton lid 12 and the inner peripheral surface of the assembly opening 21 of the front cover 20 to the inside of the housing of the gaming machine Even if it is going to insert this unauthorized tool, the unauthorized tool cannot enter the rear side of the push button retaining portion 10c. Therefore, the gaming machine including the gaming machine push button unit according to the present embodiment can prevent an illegal act with the periphery of the gaming machine push button 10 as a clue.

  The value of the ratio D / d of the outer diameter D of the push button retaining portion 10c to the inner diameter d of the assembly opening 21 is not particularly limited as long as it is larger than 1. However, if the ratio D / d is too small (too close to 1), the outer diameter D of the push button retaining portion 10c is larger than the inner diameter d of the assembly opening 21 when an error occurs in the actual product dimensions. There is a possibility that the push button retaining portion 10c becomes smaller and can pass through the assembly opening 21. The ratio D / d is appropriately determined in consideration of the dimensions of the push button 10 for gaming machines, the error, and the like.
