Abstract: A meter driving apparatus used for automotive meters such as a tachometer and a speedometer. The frequency of a pulse signal the period of which changes in correspondence with an input is calculated by counting the reference clock signals. A current corresponding to the calculated frequency is applied to two exciting coils which are orthogonal to each other, and the indicator points at the direction at the angle determined by the torque received in accordance with the magnetic field generated. A time counter adds one to the current count value whenever a predetermined time has elapsed. Even when the input pulse signal has a low frequency and the frequency rapidly changes from a high value to a low value, a temporary output is calculated from the current count value so as to prevent the degradation of the responsiveness.
