Three devices such as electric charge-coupled devices are each included in one of three phase impedance circuits composing a 3-phase LC resonance circuit as a device having a capacitive impedance. A driver circuit applies either of a logic level of 0, a high-impedance level or a logic level of 1 to each of nodes Node_A, Node_B and Node_C of the phase impedance circuits so as to result in sequential transitions of a state of resonance among the phase impedance circuits. In an operation to drive the phase impedance circuits, either of the logic level of 0, the high-impedance level and the logic level of 1 is applied to each of the nodes so as to sustain a phase difference of 2π/3 between the phase impedance circuits. In this way, the logical levels and the phases of the logical levels are assigned to the nodes in such a way that the logical levels do not overlap with each other at any timings each corresponding to a point of time. Thus, a driving apparatus for driving the devices each having a capacitive impedance is capable of reducing the power consumption.
