The scanning device includes a polygonal reflecting wheel and a reproduction device, in which a sprung objective (T0, T1, T2) is arranged and is swivelled by a control circuit (ST) via a driving device (WG, AV) synchronously with the rotary movement of the polygonal reflecting wheel, in such a way that the light signals radiated by an LED arrangement (LA) are propagated via the objective as if coming from odd image lines in one tilted position of the swivelling movement, and as if coming from even image lines in the other tilted position of the swivelling movement. <IMAGE>
