A device for separating of individual, flat objects from the underside of a stack of this kind of objects (2) includes a roll bed conveyor consisting of a plurality of circulating rollers (9) and supporting the stack from beneath, wherein the rollers (9) are respectively rotatable around their longitudinal axis (10) and are moved along an orbit (11). Hereby the rollers (9) are coupled by a coupling (8) to at least one roller wheel (7) and, by means of this coupling, the longitudinal axes (10) of the rollers (9) are respectively pivotable in relation to the roller wheel (7). The rollers (9) are pivoted in a releasing region (13) of the orbit (11), through which an opening of the roll bed conveyor is created. Thus, the flat objects (2) can individually be conveyed from beneath the stack and transported away through the opening.
