ABSTRACT:
Disclosed is an exercise amount measuring device using as an exercise signal generator an inclination detector commercially available, which can detect two-dimensional movements. Use of such inclination detectors facilitates the assembly of exercise amount measuring devices. The inclination detector1is connected to a counter circuit via an input circuit, and the input circuit and the counter circuit are connected to an MPU via an input-and-output port. The input circuit comprises a CR circuit or a flip-flop circuit. The counter circuit counts input pulses post-chattering exclusion, which input pulses are caused by the on-and-off switching actions, which are brought every time the contact ball touches selected contact electrodes in the inclination detector.
