Abstract
Device for actuating a plurality of actuators (1) in a transportation device, which has a plurality of output stages (2, 3, 4, 5) and a control circuit for actuating the output stages (2, 3, 4, 5), the output stages (2, 3, 4, 5) each connecting through the current in order to activate the actuators (1) and each output stage (2, 3, 4, 5) being connected in electrically conductive fashion to an actuator (1, 9). A plurality of output stages (2, 3, 4, 5) is additionally connected to in each case, one further actuator (1, 9) by the control circuit. The control circuit is actuated in such a way that an output stage (2, 3, 4, 5) can actuate either the first or the further actuator (1, 9) with the output stages (2, 3, 4, 5) being interconnected to one another and/or to the actuators (1, 9) in the manner of a matrix so that a plurality of row lines (6) and a plurality of column lines (7), at whose points of intersection (8) the actuators (1) are arranged, are provided.
