ABSTRACT:
A driving device includes an electro-mechanical transducer having first and second end portions opposite to each other in an expansion/contraction direction, a stationary member coupled to the first end portion of the electro-mechanical transducer, a vibration friction portion mounted to the second end portion of the electro-mechanical transducer, and a moving portion frictionally coupled to the vibration friction portion, whereby moving the moving portion in the expansion/contraction direction of the electro-mechanical transducer. The moving portion is driven by equalizing a constant expanding speed of the electro-mechanical transducer with a constant contracting speed of the electro-mechanical transducer and by setting a constant rest time interval after one of contraction of the electro-mechanical transducer and expansion of the electro-mechanical transducer.
