Abstract
To separate sheet-type recording media of different stiffnesses from a stack, a separating roller acts by friction on the current first sheet of the stack, in order to push it against a ramp and lift it up from the stack along this ramp. The separating roller is mounted in freely movable manner in a plane parallel to the plane of the stack, so that, as a function of the stiffness of the recording medium, it rolls over the stack and away from the ramp until the front edge of the sheet is able to bend sufficiently at the ramp to be separated. Thereby the separating roller adjusts automatically to the distance from the ramp that is optimum for the stiffness of the current recording media.
