ABSTRACT:
To provide an electronic pedometer in which there is adapted such that a step number is counted by a walk motion of a user, and the step number is not counted by a motion other than a walk of the user. An electronic pedometer has a timepiece case, a signal processing part having been accommodated in the timepiece case, and an acceleration sensor and a slant sensor, which have been accommodated while holding their horizontal states. The signal processing part judges, in a case where the slant sensor has outputted a horizontality signal, whether or not an acceleration signal, that the slant sensor has generated in a horizontality time till a time at which it has thereafter outputted a slant signal, is a true walk signal, when there has been judged to be the true walk signal, it performs a walk addition and, when there has been judged not to be the true walk signal, it performs a signal processing so as not to perform the walk addition.
