Device for moving a path of a moving data carrier toward and away from a surface area of a sub-carrier

A device for moving a path of a moving data carrier toward and away from a surface of a sub-carrier and particularly for moving a path of a moving paper web toward and away from a surface area of a photoconductive sub-carrier at a reproducing station of an electrostatic printer, said device comprising means supporting and moving a data carrier along a given path, said means for supporting and moving including two pivotal support members, each of said support members being mounted on a frame to pivot around respective pivot points, and means for pivoting said support members between a first position with the data carrier disposed closely adjacent the surface area of the sub-carrier and a second position with the data carrier spaced from the surface area of the sub-carrier, each of said pivot points being arranged symmetrically to a point on the surface area of the sub-carrier at which the data carrier lies closest to the sub-carrier as the support members assume said first position, each of said support members having a first data carrier engaging zone on one side of its pivot point adjacent said point on said surface area and a second data carrier engaging zone on the opposite side of its pivot point, each of said data carrier engaging zones being in continual engagement with the data carrier and of a configuration so that the data carrier is tautly engaged by said zones regardless of the position of the pivotal support members.
