Filed:

Sep 23, 1980

Appl. No.:

6/190006

Inventors:

William E. Freudenthal - Marlboro MA

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

G06K 904

US Classification:

3401463H

Abstract:

The denomination indicia contiguous with the Treasury seal on United States paper money can be located. Apparatus includes means for transporting the documents lengthwise along a course. Two reproduce heads, each having a like plurality of tracks oriented along a line substantially perpendicular to the direction of motion. Means associated with one head detect the leading edge margin of each document. Means responsive to the detection of the leading edge margin produce a set of timing pulses. A latch means responsive to the tracks of the first magnetic head upon receipt of one of the timing signals indicate the likelihood of a portion of the denomination indicia being in proximity thereto. Shift register means are responsive to the latch means. Clock pulses are applied for shifting the shift register during a time interval when the likelihood of a portion of the denomination indicia is in proximity to the first head.

Abstract:

United States paper currency can be denomination sensed by a system for scanning a predetermined path along one surface and comparing the resultant scan against a standard for a particular denomination. Subsequently, it is determined whether the scanned currency is of a particular denomination or is questionable. The one surface can be an obverse surface of paper currency, the predetermined path of the obverse surface can be magnetically scanned; the scanning direction occurs along a major axis of the currency; and the scanned currency can be sorted in accordance with the determination. Various denominations can be determined at one time either in seriatim or in parallel. In a particular form, the denomination of United States Federal Reserve Notes are sensed by magnetically scanning at least three parallel predetermined paths of an obverse surface of a note to be denomination sensed, comparing the results of the scanning against a like plurality of standards for each of the various denominations of one, two, five, ten, twenty, fifty and one hundred dollars, and determining whether the scanned note is of such one, two, five, ten, twenty, fifty, one hundred dollar denominations or is questionable. The scanned Notes are sorted in accordance with the determination.
