PROBLEM TO BE SOLVED: To provide a game machine capable of detecting in an early stage, a failure of a non-contact type ranging sensor SA.SOLUTION: In a state where a detection area RGNA of a non-contact type ranging sensor SA is made to face an area RGN' covering a stage 2310, the game machine determines whether or not a failure occurs in the non-contact type ranging sensor SA on the basis of a detection signal from the non-contact type ranging sensor SA, and causes a rotation performance lamp SAL to notify of the occurrence/non-occurrence of the failure of the non-contact type ranging sensor SA. Consequently, when energizing a Pachinko game machine 1 before opening of the game parlor, a store employee or the like can easily acquire whether the non-contact type ranging sensor SA is normally operated or abnormally operated before customers enter a game parlor, so as to easily detect whether or not a failure occurs in the non-contact type ranging sensor SA in an early stage. |
