Abstract

To enable to measure a number of steps highly accurately by dispensing with an operation of selecting a measuring mode when the number of steps is measured in walking and in running. A detecting signal detected by a walking sensor is amplified and outputted by first amplifying means by way of charge-voltage converting means. When a detecting signal by way of only the first amplifying means of the first and the second amplifying means is inputted to an input of CPU, CPU determines that a measured person is running, sets a mask time period or the like for running and carries out a processing of calculating a number of steps based on the detecting signal. When the detecting signal by way of only the first amplifying means is not inputted to the input of CPU and a detecting signal by way of both of the first amplifying means and the second amplifying means is inputted to an input of CPU, CPU determines that the measured person is walking, sets the mask time period or the like for walking and carries out the processing of calculating the number of steps based on the detecting signal.

Dependent claims

A pedometer comprising:

a sensor for detecting a moving motion of a measured person and outputting a detecting signal in correspondence therewith;
first amplifying means for amplifying to output the detecting signal from the sensor;
filter means for passing the detecting signal of a signal from the first amplifying means;
second amplifying means for amplifying to output a detecting signal from the filter means;
and
means for calculating a number of steps for calculating the 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.
