Abstract:
1. A pedometer comprising: a sensor for detecting a moving motion of a person and outputting a detecting signal in correspondence therewith; first amplifying means for amplifying the detecting signal from the sensor; filter means for passing the detecting signal from the first amplifying means; second amplifying means for amplifying the detecting signal from the filter means; first binalyzing means for binalyzing the detecting signal from the first amplifying means and second binalyzing means for binalyzing the detecting signal from the second amplifying means; and means for calculating a number of steps based on the detecting signal by way of only the first amplifying means and a detecting signal by way of the first amplifying means and the second amplifying means in the detecting signals by way of the first amplifying means and the second amplifying means; wherein the means for calculating the number of steps calculates the number of steps based on the detecting signal by way of only the first amplifying means when the detecting signal by way of only the first amplifying means is provided, and calculates the number of steps based on the detecting signal by way of the second amplifying means when the detecting signal by way of only the first amplifying means is not provided and the detecting signal by way of the second amplifying means is provided; and wherein the means for calculating the number of steps calculates the number of steps based on a detecting signal from the first binalyzing means when the detecting signal is provided from the first binalyzing means and calculates the number of steps based on a detecting signal from the second binalyzing means when the detecting signal from the first binalyzing means is not provided and the detecting signal is provided from the second binalyzing means.
