ABSTRACT:
A transfer apparatus for transferring a sheet-like medium has a vibrational element or elements which vibrate under control of electrical energy to move the sheet-like medium along a transfer medium. The vibrational element has a tubular hexagonal body with piezoelectric elements on its faces other then the upper and lower face. The lower face is fixed and the upper face has a projection in the shape of a ball which engages the bottom surface of the sheet-like medium during vibration of the vibrational element.
