PROBLEM TO BE SOLVED: To provide a game machine with a novel structure which enables the advantageous avoidance of possible fraudulence attempted to falsely generate the detection signals to be outputted from the detection means. SOLUTION: A light emitting element 54 and a photodetector 56 are provided on the main control board 52 equipped with a win/loss judging means and a light emitting side optical fiber 46a and a photodetecting side optical fiber 46b are arranged between the light emitting element 54 and the photodetector 56 and the specified passage part 44 while a reflection member 68 is disposed on the specified passage part 44. The photodetecting end face of the light emitting side optical fiber 46a is so arranged as to face the photodetecting end face of the photodetecting side optical fiber 46b through the reflection member 68.
