PROBLEM TO BE SOLVED: To simply and highly accurately suppress an erroneous detection by the repetition of a plurality of times of vibrations. SOLUTION: This game machine having vibration detection means for detecting vibration updates vibration strength presumption information to a value deviated by a vibration detection value in the direction separating from a reference value (S204) based on the detection of the vibration by the vibration detection means (S203: Y), updates the vibration presumption information to a value deviated by a non-vibration detection value in the direction returning to the reference value (S208) based on non-detection of the vibration by the vibration detection means in a case where the vibration strength presumption information is different from the reference value (S203: N), determines whether or not the vibration strength presumption information is within a tolerable vibration range between the reference value and an excess vibration threshold (S214) and, when the vibration strength presumption information is not within the tolerable vibration range, concludes it as the excess vibration.
