Bill validator with bar code detector
DCFirst Claim
1. A bill validator, comprising:
- conveyor means for transporting a bill inserted from an inlet to an outlet along a passageway;
sensor means positioned in the vicinity of said passageway for detecting a magnetic or optical feature of the bill;
a bar code detector means for photoelectrically converting bar code pattern printed on a document inserted into said inlet into electric signals, said bar code detector means connected with a discriminator means;
said discriminator means for receiving signals from said sensor means to generate outputs in order to drive said conveyor means when said discriminator means detects a predetermined magnetic or optical pattern for a genuine bill, wherein said discriminator means comprises a bar code memory for storing predetermined bar code patterns and a bar code comparator for comparing bar code signals read out through said bar code detector means with bar code signals stored in said bar code memory, after or before said discriminator means decides whether said document is a genuine bill, said bar code comparator generating a drive signal to said conveyor means to transport said document to said outlet when said bar code comparator detects coincidence of said bar code signals from said sensor means and bar code memory.

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.
