Abstract: The device claimed by the invention is characterized essentially in that during the transport of a flat object, in particular, a banknote, through guide elements the deflection of one or two second guide elements from a first guide element is detected via an electrically conductive element by one or more flat air core coils. In the process a magnetic alternating field is generated which is influenced by a change of position of the electrically conductive element. The alternating field causes eddy currents in the electrically conductive element. These eddy currents in turn influence the alternating field. When the flat coils are each a part of an LC oscillating circuit, for example, the resonance frequency and the attenuation of this oscillating circuit are influenced. At a constant excitation frequency the amplitude of the oscillations varies.
