US Patent 7778536 Driving apparatus

An anti-vibration unit serving as a driving apparatus has an X axis transducer having a driver, a fixed frame having an X axis transducer holding part, an X frame having a sliding body against which the driver is pressed by a pressing plate with an anti-vibration sheet and a holder interposed therebetween, a Y axis transducer having a driver, and a Y frame having a sliding body against which the driver is pressed by the pressing plate with the anti-vibration sheet and the holder interposed therebetween. The anti-vibration sheet is narrower than the transducer, and grease is applied to one of the surfaces of the anti-vibration sheet and the pressing plate in contact with each other, so that the drivers are in proper contact with the sliding bodies, and the sliding bodies are efficiently driven. The driving apparatus is compact and produces high driving force with high efficiency.
