Specifically, if the magnitude of the acceleration is equal to or greater than the first threshold value, it is determined that the first predetermined criterion (first criterion) is satisfied. If the magnitude of the acceleration is equal to or greater than the second threshold value and less than the first threshold value, it is determined that the second predetermined criterion (second criterion) is satisfied. On the other hand, if the magnitude of the detected acceleration is less than the second threshold value, it is determined that the predetermined criterion is not satisfied.
