Abstract
A pedometer measures the walk of a person and has an operating portion operated by the person to change the display mode. When operation of the operating portion is detected, a CPU proceeds to a walk determining mode, counts a walk signal from an acceleration sensor to successively store to a walk step number buffer memory, proceeds to a walk step number measuring mode when walking is determined in the walk determining mode, adds the walk step number stored to a walk step number memory, thereafter, continuously measures the walk step number, and adds the walk signal to the walk step number of the walk step number at each time of receiving the walk signal from the acceleration sensor. In this manner, operation of the operating portion to change display modes is not erroneously detected as a walk, thereby improving the measurement accuracy.
