ABSTRACT:
A sheet feed roller that rotates intermittently has a contact face for contacting with the surface of a sheet and a non-contacting face that does not contact with the surface of a sheet. A holder opposed to a circumferential face of the sheet feed roller has a recess on the surface thereof. A separation pad made of a material having a high coefficient of friction is disposed in a portion of the recess upstream in a feeding direction of a sheet, while a PET film serving as a noise deadening control element made of a material having a low coefficient of friction is disposed in another portion of the recess adjacent to the separation pad downstream in the feeding direction such that the surface thereof has a height substantially equal to that of the surface of the separation pad. The sheet feed roller is disposed such that the contact face thereof extends over both the separation pad and the noise deadening control element. The construction is effective to prevent noise generated by a sheet frictionally separated and supplied by the separation pad having a high coefficient of friction and the sheet feed roller or by vibrations of the holder member.
