Abstract:
1. An electronic pedometer comprising: an acceleration sensor that detects acceleration in vertical movement of a user's body during a walking movement of the user to output a walk signal corresponding to the detected acceleration; calculation means for calculating a number of walking steps of the user based on the walk signal; and a strap for mounting the electronic pedometer on a wrist of the user's body; wherein the acceleration sensor has a sensitivity axis along which a detection sensitivity by the acceleration sensor of the acceleration in vertical movement of the user's body during the walking movement becomes a maximum; and wherein when the acceleration sensor is mounted on a left wrist of the user's body, the sensitivity axis of the acceleration sensor is located within a range of less than 30 degrees in the counterclockwise direction from an axis disposed at 90 degrees with respect to the longitudinal direction of the strap.
