PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can prevent a drop in the visual recognizability of a glass plate. SOLUTION: The Pachinko game machine can stop dusts or others with flexible printed circuit boards 105 and 107 even when coming inside the unit frame 71 through vent holes 95 from outside the unit frame 71 to block the dusts from further invading into a closed space of the unit frame 71. In addition, the vent holes 95 are installed in the unit frame 71 and the air warmed in the closed space of the unit frame 71 by emission heat from light-emitting diodes 106 and 108 of the flexible printed circuit boards 105 and 107 provided on the inner circumferential surface of the unit frame 71 is discharged outside the unit frame 71 through the vent holes 95. This enables the removal of the dew condensation as early as possible as caused by the moisture in the closed space, thereby preventing the drop in the visual recognizability of the glass plate 80.
