1. An electronic combined pulse meter and pedometer comprising:

  • pulse wave detecting means for detecting an input heartbeat pulse wave and providing a corresponding detected pulse wave output signal;

    clock signal generating means for generating a clock signal;

    calculating means receptive of the detected pulse wave output signal and the clock signal for calculating the time interval between a predetermined number of pulses of the detected pulse wave output signal in accordance with the flock signal;

    pulse wave level storing means for storing a predetermined pulse wave level for use as a reference level for discriminating whether the detected pulse wave output signal is indicative of an at rest state or a walking state of a user;

    walking state detecting means for detecting whether the user is at rest or walking by comparing the detected pulse wave output signal from the pulse wave detecting means with the predetermined pulse wave level stored in the pulse wave level storing means and for providing a walking state signal when the level of the detected pulse wave output signal exceeds the predetermined pulse wave level;

    constant value storing means for storing a plurality of pre-set pulse rates and walking pace values;

    calculation control means for controlling the calculating means in accordance with the walking state signal, and for selecting pre-set pulse rate and walking pace values from the constant value storing means based on the calculated time interval between a predetermined number of pulses of the detected pulse wave output signal and the walking state signal; and

    display means receptive of the calculated time interval between a predetermined number of pulses of the pulse wave output signal and the selected pulse rate and walking pace values for selectively displaying the user'"'"' pulse rate or walking pace in accordance with the walking state signal.
