Abstract
A paper feeding apparatus comprises a flexible vibrating body made of an elastic matter. The body is excited with a resonant frequency so as to produce a progressive wave. A driving vibrator is fixed to one end of the flexible vibrating body, and a receiving vibrator is fixed to the other end thereof. A mechanism is included for urging paper against the flexible vibrating body, so that when the vibrating body is excited, the paper is conveyed.
Claims18
