ABSTRACT:
A sheet feeding apparatus includes a vibration member having an upper surface, a bottom surface, an inner circumferential portion and an outer circumferential portion, and further having a first portion in press contact with the sheet being fed and a second portion substantially out of contact with the sheet while the sheet is being fed. An electromechanical energy conversion element is provided on the bottom surface of the vibration member and generates a vibration wave in the first portion of the vibration member in response to an applied electrical signal, the vibration wave creating a driving force for moving the sheet.
