Abstract
A driving apparatus having a driving pulse generator including a high-speed electrifying circuit and a low-speed electrifying circuit connected to a transducer; and a controller which sets a low-speed electrification time to a first specified time, sets a time from a low-speed electrification start time to a high-speed electrification start time to a second specified time, makes the low-speed charging duration shorter than the first specified time during low-speed driving and makes a time period from a low-speed charging start time to a high-speed discharging start time shorter than the second specified time.
