A speedometer/odometer apparatus, wherein a sensor inputs an electronic sensing signal to an amplifier and a selecting device to be amplified and output as a stable single stroke signal. The signal is combined with a frequency signal from a crystal oscillator and divided into regular pulses. The frequency of the pulses is divided by a frequency divider circuit and output as two signals with high accuracy for respectively controlling the speed indication of the speedometer and mileage indication of the odometer.
