PROBLEM TO BE SOLVED: To simply and highly accurately suppress an erroneous detection by the repetition of a plurality of times of vibrations.SOLUTION: A 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 a value within the tolerable vibration range, concludes it as an excess vibration. |
