Abstract

A driving apparatus is provided including a current detecting device for detecting electric current flowing through elements such as a sensor, a heater and an actuator, and switching devices for controlling electric current through the elements. The number of electric current detecting devices is reduced by using the devices in common. Switching the switching devices on-and-off is repeated. The electric current flowing in the element, which is to be detected, is detected by separation from another electric current that flows in the other elements
