Abstract

PURPOSE:To prevent the squeak of a sheet by fixing a separating pad onto a supporting member through a vibrationproof member and allowing the vibration which the separating pad generates during the feed of the sheet to be absorbed by the vibrationproof member. CONSTITUTION:A separating pad 5 is fixed onto a lower guide plate through a vibrationproof member 16 consisting of the vibrationproof sheets made of rubber, etc. In this constitution, if a shaft 6 is revolved by a motor, the sheets S on a cassette 11 are separated one by one and transported in the frictional contact with the separating pad 5 by a paper feeding roller 1 which is formed integrally with the shaft 6 and a cam 2. Though, in this case, vibration is generated on the separating pad 5, said vibration is absorbed by the vibrationproof member 16, and generation of squeak of the sheet S is prevented.
