  Next, FIG.9 (b) is sectional drawing which looked at the sealing member 500 from the side. The sealing member 500 is a two-layer seal of an adhesive layer 500U and a surface layer 500D. The surface layer 500 </ b> D is adhered to the adhesive layer 500 </ b> U with an adhesive that can be removed. The surface layer 500D has a weakened portion 501a that is partially weaker than the surrounding portion, and a portion of the adhesive layer 500U located above the weakened portion 501a forms a hidden character portion 501.

  Next, FIG.10 (c) is sectional drawing which looked at a mode that the sealing member 500 is being peeled off from the side. By removing the sealing member 500, the weakened portion 501a of the surface layer 500D is cut off from the surroundings to form a cut off portion 501a ′. The portions where the cut portions 501a ′ are cut off are separated from the two-layer structure formed by the adhesive layer 500U and the surface layer 500D by removing the surface layer 500D, and become a thin portion only of the adhesive layer 500U. . Since these thin portions have higher transparency than other portions, a character portion 501 ′ described later appears. In this manner, when the sealing member 500 once pasted is removed, for example, characters “opened” appear. When the sealing member 500 once affixed in this manner is removed, the adhesive strength of the portion where the cut-off portion 501a ′ of the adhesive layer 500U is cut off is weakened, and the cut-off portion 501a ′ is bonded again to the adhesive layer 500U. Thus, the weak part 501a is not restored, and the character part 501 'remains. Therefore, the trace from which this sealing member 500 was removed remains, and early detection that the sealing member 500 was removed is enabled.

  Next, FIG.10 (d) is the front view which looked at the sealing member 500 once peeled off after being affixed once. Since the sealing member 500 has a weakened portion layer that is relatively weaker than the surroundings, when completely removed, for example, the character portion from the hidden character portion 501 in which characters “opened” are formed is formed. 501 ′ appears completely.

  In this embodiment, it is assumed that the sealing surface formed by sealing the opening of the case 200 by attaching the lid 100 to the case 200 is a flat surface. Therefore, the power supply box 400 of the gaming machine 1 is used as the sealing surface. It is assumed that the side wall 19 and the lid 100 can be brought into close contact with each other when being fixedly disposed on the side wall 19 inside the housing. However, the present invention is not limited to this, and the sealing surface formed by sealing the opening of the case 200 by attaching the lid 100 to the case 200 may not be a flat surface. For example, the power supply box 400 as shown in FIG. As shown in the cross-sectional view from the front of the gaming machine 1 that is attached to 19, as long as the surface includes at least all four sides on the side of the arrow A in FIG. You may contact | connect so that it may contact | adhere to the side wall 19 partially. Even the contact surface 600 includes at least the peripheral portion of the sealing member and is a close contact surface where the sealing surface and the side wall 19 are in contact with each other without any gap. Therefore, in order to remove the lid 100 as the sealing member from the case 200, first, the case 200 must be removed from the side wall 19 of the gaming machine 1, and in order to complicate the procedure of removing the lid 100, the lid 100 is removed from the case to prevent and deter unauthorized acts on electronic components including the power supply control board 300. be able to.
