PROBLEM TO BE SOLVED: To provide a game machine being hard to recognize a disposition position of loudspeakers and the like from the front side. SOLUTION: Respective recesses 71 having predetermined small diameter and predetermined depth hardly visible the bottoms are formed almost whole surface of the front face of a front side flat plate part 64 of a front lid member 61 at a predetermined alignment pattern. Parts corresponding to respective loudspeakers 11A in the backside of the front side flat plate part 64 are erected with approximately laterally-long elliptical attachment ribs 73, the respective recesses 71 disposed in the inside parts (loudspeaker hole area) of the respective attachment ribs have the bottom parts penetratedly connected to the through-holes 75 communicated with the backside to constitute sound emission ports in the front face direction of the respective loudspeakers 11A. The bottoms of the respective recesses 71 disposed in the inside part (bass reflex hole area) of the bass reflex ribs 76 with approximately square cross section are penetratedly connected to the through-holes 75 communicated to the backside to constitute sound emission ports emitting the sound in the backside direction of the respective loudspeakers 11A.
