Abstract
A sheet feed mechanism has an array of suction cups into and out of contact with an uppermost one of stacked sheets in a sheet cassette. After the suction cups are held against the uppermost sheet, a vacuum is developed in the suction cups to enable the suction cups to attract the uppermost sheet. Then, the suction cups are lifted with the uppermost sheet attracted thereto, and a leading end of the attracted and lifted uppermost sheet is nipped, and the sheet is delivered into a sheet feed path. When the suction cups are lifted, they are angularly moved about an axis to cause the leading end of the attracted uppermost sheet to be obliquely separated from other stacked sheets.
