Abstract
A sheet feeding mechanism for feeding sheets is described including an advance preventive member which is abuttable on the sheet feeding roller by a spring. The advance preventive member functions to prevent multiple feeding of sheets. The sheet feeding cassette has a first sheet advance preventive part which acts on a second sheet advance preventive part on the advance preventive member when the sheet feeding cassette is moved toward or away from the sheet feeding roller, to thereby separate the advance preventive member from the sheet feeding roller against the urging force of a spring. Specific designs of the first and second sheet advance preventive parts may be included to vibrate and rotate a roller of the advance preventive member.
