Abstract: A drive apparatus for a cross-coil type meter has cross-coils formed of a first and a second coil disposed intersecting at the center thereof. A magnet rotor is disposed in a magnetic field set up by the cross coils, and a measurement is represented in terms of a rotational angle of the magnet rotor. The drive apparatus comprises a first supply means for supplying the first coil with a first square wave current having a duty cycle of a% in accordance with the measurement; a second supply means for supplying the second coil with a second square wave current having a duty cycle of (100-a)% complementary to the first square wave current; and a polarity setting means for setting in accordance with the measurement polarities of the first square wave current and the second square wave current.
