Abstract:
1. A device for determining a thickness or thickness variation of a flat object in particular a voucher, having at least one first guide element, and having a plurality of second elements disposed adjacent to one another in a row and opposite the first guide element, wherein the flat object can be transported between the first guide element on one side and the second guide elements on the other side, and having a displaceable arrangement of the second guide elements relative to the first guide element in order to bring about a deflection of one or more of the second elements relative to the first guide element in the event of a thickness variation of the flat object running between the guide elements, and having a plurality of coils fixed in location wherein each second guide element is associated with at least one coil, and having at least one coil core rigidly connected to each second guide element and displaceably guided in the coil associated with the second guide element, wherein a deflection of a second guide element brings about a deflection of the associated coil core; a printed circuit board having a plurality of openings, the coils being disposed on the printed circuit board and surrounding the openings; and said coil cores being displaceable relative to the openings in the printed circuit board.
