Abstract
Abstract A bill-discriminating apparatus which is used, for example, in an automatic deposit machine and which discriminates a bill by comparing patterns read from the bill with standard patterns. The apparatus includes a circuit for reading patterns from a conveyed bill, one or more sensors for determining the conveyance condition of the bill, a circuit for generating standard patterns corresponding to the conveyance condition of the bill and/or to the kind of bill, and a circuit for comparing the patterns, read from the bill by the circuit for reading patterns, with the standard patterns, thereby discriminating the truth of falsity of the bill and/or the kind of bill.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
277 words
A bill-discriminating apparatus, including a frame having a slot defining a passage which has an input end through which a bill is conveyed, for discriminating a conveyed bill by comparing patterns read from the bill with standard patterns, said bill discriminating apparatus comprising: means for reading patterns from the conveyed bill; one or more sensors, operatively connected to said means for reading patterns, for determining the conveyance condition of the bill; means, operatively connected to said one or more sensors, for generating the standard patterns corresponding to the conveyance condition of the bill and the denomination of the bill by dividing a predetermined area of the bill into sections, said means comprising: a model map memory for storing the standard patterns provided by said means for generating the standard patterns; and zone address-selecting means, operatively connected to said model map memory, for supplying address data to said model map memory in order to read out the standard patterns corresponding to the conveyance condition of the bill and denomination of the bill, said zone address-selecting means generating said address data in dependence upon information concerning the conveyance condition of the bill, including the amount of tilt of the bill, information regarding the width of the bill, deviation of the bill in the passage in the direction of a line perpendicular to the direction of the conveyance of the bill, the conveyance speed of the bill, and the denomination of the bill; and means, operatively connected to said means for reading patterns, for comparing the patterns read from the bill with the standard patterns, thereby discriminating the denomination of the bill and whether the bill is real or counterfeit.
Claim 2
Dependent Claim
277 words
A bill-discriminating apparatus, including a frame having a slot defining a passage which has an input end through which a bill is conveyed, for discriminating a conveyed bill by comparing patterns read from the bill with standard patterns, said bill discriminating apparatus comprising: means for reading patterns from the conveyed bill; one or more sensors, operatively connected to said means for reading patterns, for determining the conveyance condition of the bill; means, operatively connected to said one or more sensors, for generating the standard patterns corresponding to the conveyance condition of the bill and the denomination of the bill by dividing a predetermined area of the bill into sections, said means comprising: a model map memory for storing the standard patterns provided by said means for generating the standard patterns; and zone address-selecting means, operatively connected to said model map memory, for supplying address data to said model map memory in order to read out the standard patterns corresponding to the conveyance condition of the bill and denomination of the bill, said zone address-selecting means generating said address data in dependence upon information concerning the conveyance condition of the bill, including the amount of tilt of the bill, information regarding the width of the bill, deviation of the bill in the passage in the direction of a line perpendicular to the direction of the conveyance of the bill, the conveyance speed of the bill, and the denomination of the bill; and means, operatively connected to said means for reading patterns, for comparing the patterns read from the bill with the standard patterns, thereby discriminating the denomination of the bill and whether the bill is real or counterfeit.
Claim 3
Dependent Claim
79 words
An apparatus according to claim 1, wherein the apparatus further comprises means, operatively connected to said means for comparing patterns, for temporarily determining the denomination of the bill in accordance with the information concerning the width of the bill and in accordance with said means for comparing the patterns read from the bill with the standard patterns and for determining the bill as being a real bill when the patterns read from the bill coincide with the standard patterns.
Claim 4
Dependent Claim
42 words
An apparatus according to claim 2, wherein the apparatus further comprises two skew-sensing means, arranged in the passage in the direction of a line perpendicular to the direction of conveyance of the bill, for determining the amount of tilt of the bill.
Claim 5
Dependent Claim
43 words
An apparatus according to claim 2, wherein the apparatus further comprises one or more position sensors, arranged on either side of the passage, for sensing the position of one or more edges of the bill and thereby determining the width of the bill.
Claim 6
Dependent Claim
188 words
A bill-discriminating apparatus including a slot defining a passage which has an input end through which a bill is conveyed, for discrimiating the conveyed bill by comparing patterns read from the bill with standard patterns, said bill discriminating apparatus comprising: means for reading patterns from the conveyed bill; position sensing means including a plurality of sensor elements, arranged in one or more rows extending at an angle with respect to a line parallel to the direction of conveyance of the bill, for sensing the position of a edge of the bill; skew sensing means, operatively connected to said position sensing means, for determining the amount of tilt of the bill in the passage, thereby determining the conveyance condition of the bill; means, operatively connected to said skew sensing means, for generating the standard pattern corresponding to the conveyance condition determined by said skew sensing means and the denomination of the bill; and means, operatively connected to said means for reading patterns, for comparing the patterns read from the bill with the standard patterns, thereby discriminating the denomination of the bill and whether the bill is real or counterfeit.
Claim 7
Dependent Claim
188 words
A bill-discriminating apparatus including a slot defining a passage which has an input end through which a bill is conveyed, for discrimiating the conveyed bill by comparing patterns read from the bill with standard patterns, said bill discriminating apparatus comprising: means for reading patterns from the conveyed bill; position sensing means including a plurality of sensor elements, arranged in one or more rows extending at an angle with respect to a line parallel to the direction of conveyance of the bill, for sensing the position of a edge of the bill; skew sensing means, operatively connected to said position sensing means, for determining the amount of tilt of the bill in the passage, thereby determining the conveyance condition of the bill; means, operatively connected to said skew sensing means, for generating the standard pattern corresponding to the conveyance condition determined by said skew sensing means and the denomination of the bill; and means, operatively connected to said means for reading patterns, for comparing the patterns read from the bill with the standard patterns, thereby discriminating the denomination of the bill and whether the bill is real or counterfeit.
Claim 8
Dependent Claim
36 words
An apparatus according to claim 5, wherein said plurality of sensor elements of said position sensing means are arranged in one or more rows which are substantially perpendicular to the direction of conveyance of the bill.
Claim 9
Dependent Claim
42 words
An apparatus according to claim 5, wherein said means for reading patterns is disposed within the passage adjacent to said plurality of sensor elements of said position sensing means and located at a position farthest from the input end of the passage.
Claim 10
Dependent Claim
42 words
An apparatus according to claim 6, wherein said means for reading patterns is disposed within the passage adjacent to said plurality of sensor elements of said position sensing means and located at a position farthest from the input end of the passage.
