Abstract
A bill validator which may validate bills and bar coded documents is provided. A central processing unit of the bill validator comprises discriminator means for receiving outputs of sensor means for detecting magnetic or optical feature of the bills; and bar code detector for photoelectrically converting bar code pattern printed on a document. The discriminator means comprise an bar code comparator for receiving outputs of the optical sensors to detect bar code printed on a document; a magentic pattern memory for storing predetermined magnetic patterns; and bar code memory for storing predetermined bar code patterns. The bar code comparator compares bar code signals read out through optical sensors from the document with bar code signals stored in the bar code memory after or before the discriminator means decides whether the document is a genuine bill or not. When the bar code comparator detects coincidence of the bar code signals from the optical sensors and bar code memory, it generates coincident signal to supply a drive signal to the meter control circuit of the conveyor means in order to transport the bill to the outlet.
