<P>PROBLEM TO BE SOLVED: To provide a synchronous rotating device capable of miniaturization of the device, and also, easily and accurately synchronizing several rotating drums, as the synchronous rotating device for synchronously rotating the several rotating drums. <P>SOLUTION: A color printer 1 is provided with 1st to 4th rotating drums 3 to 6 arranged so as to be synchronously rotated. An ultrasonic motor 7 equipped with a stator for generating vibration and a rotor which is rotated in press contact with the stator based on the vibration of the stator, is stored inside the 1st rotating drum 3. The 1st rotating drum 3 is fixed to an output disk 20 connected to the rotor of the ultrasonic motor 7. Pulleys 3a to 6a are arranged in the 1st to 4th rotating drums 3 to 6, and the pulleys 3a to 6a are connected through the belt 8. <P>COPYRIGHT: (C)2003,JPO |
