Abstract
A sheet feed device for feeding a sheet in a copying machine includes a sheet cassette storing a stack of sheets therein and removably positioned in a housing of the copying machine, and a plurality of suction cups for attracting one of the sheets at a time from the sheet cassette. The suction cups are movable toward and away from the sheet cassette. Locking fingers lock the sheet cassette against removal when the suction cups are moved toward the sheet cassette and are ready for or are feeding sheets from the sheet cassette. The locking fingers are angularly movably supported in the housing and lockingly fittable in recesses defined in side walls of the sheet cassette.
