ABSTRACT:
A sheet-supply device supplying sheets one at a time from a stack of sheets in a sheet feeding direction. The device includes a slanting plate on which a stack of sheets is mounted. A sheet feed roller is positioned above the slanting plate applying a force to an uppermost sheet in the stack to move the sheet in a sheet feed direction. A fixed separation plate is fixed at a downstream end portion of the slanting plate. The separation plate is formed with a slot in which a high friction separation member is disposed. The high friction separation member is held by a resilient support plate39supported by the fixed separation plate. The resilient support plate has a comb like slats on which the high friction separation member is held. In a normal condition, the high friction separation member protrudes from the slot toward the leading edges of the sheets. When a leading edge of the sheet presses the high friction separation member by the rotation of the sheet feed roller, and the sheet has a predetermined stiffness, a part of the high friction separation member sinks into the slot by the deformation of the comb like slats.
