ABSTRACT:
There is disclosed a separator device for singularly passing to a transport member a rectangular sheet of material from a stack of such sheets accommodated in a storage cassette having a rectangular slotted sheet discharge opening. The cassette is provided with a hold-down plate for pressing the uppermost sheet against a bulge forming means disposed adjacent the discharge opening and comprised of a pushing member. The bulge forming means is controlled by a first cam disc adapted to perform a reciprocating movement to engage the leading edge of the uppermost sheet whereby such sheet is partly released from the stack by bulging at the discharge opening. Adjacent the bulging produced on one side edge of the sheet there is disposed a catching means comprised of a hook and controlled by a second cam disc adapted to lift the leading portion of the uppermost sheet such that after release of the uppermost sheet by said catching means, the sheet is caused to lie on a sheet guide means whereby transport rollers can further move the sheet. A third cam disc is provided to impart a reciprocating movement to the sheet guide means having a receding leading edge relative to the storage cassette proximate to the pushing member.
