Abstract
Abstract A bank note checking apparatus which is used, for example, in an automatic deposit machine and which checks a bank note by comparing patterns read from the bank note (1) with reference patterns includes means (P,) for reading patterns from a conveyed bill and one or more sensors (T 1, T 2 . W 1 , W 2 ) for determining the physical condition of the bank note (1) during conveyance. The apparatus also includes means for generating an appropriate reference pattern from stored standard patterns (9) in accordance with the sensed physical condition of the bank note (1) and means (11) for comparing the patterns read from the bank note (1) by the means (P 1 ) for reading patterns with the generated reference pattern, thereby determining the validity and/or denomination of the bank note (1). Typically the sensors (T 1 , T 2 , W 1 , W 2 ) monitor the size of the bank note (1) and its orientation with respect to the means (P 1 ) for reading the patterns so that the size and any tilt or transverse displacement of the bank note (1) is taken account of in the generation of the reference pattern.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
A bank note checking apparatus for determining the denomination and/or checking the validity of a bank note by comparing patterns read from the bank note with a reference pattern, comprising -means to convey bank notes (1), means (P l ) for reading patterns from a bank note (1) as it is conveyed past the means (P 1 ), one or more sensors (T 1 ,T 2 ,W 1 ,W 2 ) for determining a physical condition of the bank note during conveyance, means (4, 1Q) for generating an appropriate reference pattern from stored standard patterns (9) in accordance with the sensed physical condition of the bank note (1), and means (11) for comparing the patterns read from the bank note (1) by the means (P 1 ) for reading patterns with the generated reference patterns, thereby determining the validity and/or the denomination of the bank note (1).
Claim 2
Dependent Claim
147 words
A bank note checking apparatus for determining the denomination and/or checking the validity of a bank note by comparing patterns read from the bank note with a reference pattern, comprising -means to convey bank notes (1), means (P l ) for reading patterns from a bank note (1) as it is conveyed past the means (P 1 ), one or more sensors (T 1 ,T 2 ,W 1 ,W 2 ) for determining a physical condition of the bank note during conveyance, means (4, 1Q) for generating an appropriate reference pattern from stored standard patterns (9) in accordance with the sensed physical condition of the bank note (1), and means (11) for comparing the patterns read from the bank note (1) by the means (P 1 ) for reading patterns with the generated reference patterns, thereby determining the validity and/or the denomination of the bank note (1).
Claim 3
Dependent Claim
76 words
An apparatus according to claim 1, in which the one or more sensors for determining a physical condition of the bank note (1) comprises at least one position sensor (W 1 ,W 2 ) located beside the means to convey the bank notes (1) sensing the position of an edge of the bank note (1) to determine its size, and skew sensing means (T1,T2) for determining the amount of tilt of the bank note (1) .
Claim 4
Dependent Claim
32 words
An apparatus according to claim 2, which includes two position sensors (W 1 ,W 2 ) located on opposite sides of the path of the bank notes (1) through the appara-tus .
Claim 5
Dependent Claim
56 words
An apparatus according to claim 2 or 3, in which the or each of the position sensors (W 1 ,W 2 ) comprises a plurality of sensor elements (S 1 to S 16 ) arranged in one or more rows inclined to or perpen- di cular to the direction of conveyance of the bank note (1).
Claim 6
Dependent Claim
30 words
An apparatus according to claim 4, in which the means (P 1 ) for reading patterns is located within the area of the outermost sensor elements of the position sensors.
Claim 7
Independent Claim
41 words
An apparatus according to any one of claims 2 to 5, in which the skew sensing means comprises two sensors (T l ,T 2 ) spaced apart in a direction transverse to the direction of conveyance of the bank notes (1)
Claim 8
Dependent Claim
20 words
An apparatus according to claim 6, in which the two sensors (T l and T 2 ) are optical sensors.
Claim 9
Dependent Claim
26 words
An apparatus according to claim 7, in which the two optical sensors of the skew sensing means are also used as the means for reading patterns.
Claim 10
Dependent Claim
38 words
An apparatus according to claim 3 or any one of claims 4 to 8 when dependent upon claim 3, which does not include mechanical guides to define the location or orientation of the bank note (1) being conveyed.
Claim 11
Independent Claim
29 words
An apparatus according to any one of claims 1 to 8, in which means are provided to locate one edge of the bank notes (1) as they are conveyed.
Claim 12
Independent Claim
112 words
An apparatus according to any one of the preceding claims, in which means for generating an appropriate reference patterns from stored standard patterns in accordance with the sensed physical condition of the bank note (1) comprises a model map memory (9) which stores standard pattern data of a number of adjacent zones of one or more valid bank notes, and zone address-selecting means (4) which is fed with an output from the one or more sensors (T 1 ,T 2 ,W 1 ,W 2 ) and which supplies address'data to the model map memory (9) to read out the reference pattern data corresponding to the physical condition of the bank note (l).
Claim 13
Dependent Claim
86 words
An apparatus according to claim 11, in which the zone address-selecting means (4) generates the address data on the basis of information from the sensors .(T 1 ,T 2 ,W 1 ,W 2 ) concerning one or more of the following: the amount of tilt of the bank note (1), the location of the bank note (1) in the direction transverse to the directing conveyance, the speed of conveyance of the bank note (1), and the length and hence the denomination of the bank note (1).
Claim 14
Dependent Claim
61 words
An apparatus according to claim 11 or 12, in which the denomination of the bank note is temporarily determined on the basis of its sensed length, which at least partly determines the reference pattern, and then the validity of the bank note (1) is determined by comparing the patterns read from the bank note (1) with the selected reference pattern .
