Pedometer
First Claim
1. A pedometer comprising:
- a sensor that detects a moving motion of a person and that outputs a detecting signal in correspondence therewith;
a filter to which is inputted the detecting signal from the sensor and which has a variable passing frequency band;
filter controlling means for switching the passing frequency band of the filter to either of a band for walking and a band for running;
step number calculating means for calculating a number of steps based on the detecting signal passing through the filter;
signal level determining means for determining a level of the detecting signal passing through the filter; and
moving motion determining means for determining that the moving motion is changed from walking to running when the signal level determining means determines that a signal level of the detecting signal is at a predetermined level or higher and the detecting signal from the filter set to the band for running is at a period within a predetermined range;
wherein when the moving motion determining means determines running, the filter controlling means maintains the passing frequency band of the filter to a state of setting the band for running, and the step number calculating means calculates the number of steps based on the detecting signal passing the filter.

Abstract
To dispense with an operation of selecting a measuring mode and enabling to measure with high accuracy a number of steps in walking and in running. A detecting signal in correspondence with walking or running outputted from a sensor is inputted to CPU by way of an amplifying circuit, a filter circuit having a variable passing frequency band, an amplifying circuit, a waveform shaping circuit to count a number of steps. In a walking state, when a voltage comparing circuit determines that a signal level of a detecting signal S2 is equal to or higher than a predetermined level and a detecting signal S2 from the filter circuit set to a band for running is at a period within a predetermined range, CPU determines that a moving motion is changed from walking to running, maintains a state in which a frequency switching circuit sets a passing frequency band of the filter circuit to a band for running, sets to maintain the amplifying circuit by a gain for running and calculates a number of steps based on a detecting signal S1 passing the filter circuit.
