A banknote validator includes a first sensor unit, a second sensor unit, a correction parameter operating unit, and a distinguishing unit. The first sensor unit includes a first projecting section and a first receiving section for projecting and receiving a portion of a first light beam reflected off a received banknote generating a first receiving section signal. The second sensor unit has a second projecting section and a second receiving section for projecting a second light beam and receiving a portion of the second light beam reflected off the received banknote generating a second receiving section signal. The correction parameter operating unit receives the first receiving section signal and produces a correction parameter signal for the distance between the banknote and the second sensor unit. The distinguishing unit receives the second receiving section signal and the first correction parameter signal and determines the validity of the received banknote.
