A device for separating sheets (10) of a recording medium stored in a horizontally disposed stack includes an advance roller (16) resting on the stack and following the decreasing height of the stack. The advance roller (16) is drivable in order to acquire the topmost sheet (10.1) of the stack under frictional closure and to slide it for separation with its leading edge up on an obliquity (14). In order to be able to separate sheets (10) of different stiffness, the advance roller (16), while it is driven on the topmost sheet (10.1), drifts from the obliquity (14) until the leading edge of the sheet (10.1) runs up on the obliquity (14). The advance roller (16) is movable vertically. The counter force acting during the driving of the advance roller (16) is additionally supported in a rocker in order to increase the contact pressure against the topmost sheet (10.1) in case of the sheets of great stiffness.
Device for isolating sheets of a recording medium, in which the sheets are stored in a stack essentially disposed horizontally, with an advance roller resting on the stack and following the decreasing height of the stack, which is drivable in order to acquire the topmost sheet of the stack under frictional closure and to slide it for the purpose of isolation with its leading edge against an obliquity, adjoining the stack and rising relative to the sheet plane, wherein the advance roller, while it is being driven on the topmost sheet, moves away from the obliquity until the leading edge of the sheet runs up on the obliquity, characterized in that the advance roller (16) is supported vertically freely movably and that the counter force corresponding to the advance force onto the advance roller blocks the vertical movability of the advance roller (16).
Device for isolating sheets of a recording medium, in which the sheets are stored in a stack essentially disposed horizontally, with an advance roller resting on the stack and following the decreasing height of the stack, which is drivable in order to acquire the topmost sheet of the stack under frictional closure and to slide the topmost sheet for the purpose of isolation with its leading edge against an obliquity, adjoining the stack and rising relative to the sheet plane, wherein the advance roller, while being driven on the topmost sheet, moves away from the obliquity until the leading edge of the sheet runs up on the obliquity, characterized in that the advance roller (16) is supported vertically freely movably and that the counter force corresponding to the advance force onto the advance roller blocks the vertical movability of the advance roller (16), characterized in that the advance roller (16) is supported on the free end of an arm (38) which movably follows the height of the stack and that the movement of the arm (38) is blocked through the counter force.
