ABSTRACT:
A device which removes dust and/or other impurities from photographic films, records or other data carriers has one or more brushes whose bristles sweep along the surface or surfaces of a data carrier while the data carrier moves relative to the bristles and/or vice versa. The electrostatic charge which develops as a result of frictional engagement between the data carrier and the bristles is led away by providing each brush with bristles at least some of which consist of conductive material and are grounded via electrodes which contact the tips of the bristles and/or by way of the core of each brush.
