Apparatus for and method of discriminating bill

Claim 2

A bill discriminating apparatus according to Claim 1, wherein the bill scale data selection means compares the discriminated data with a given slice value and fetches the discriminated data having the value greater than the slice value as the bill scale data.

Claim 3

A bill discriminating apparatus according to Claim 2, wherein the bill scale data selection means selects addresses representing four corners of the discriminated bill among the fetched bill scale data.

Claim 4

A bill discriminating apparatus according to Claim 1, wherein the data arithmetic means calculates average values of segmented scale data in each block area while the standard data storage means holds each standard average value data as each standard arithmetic data in every bill, the bill decision means totals absolute values of the difference between each standard average value data and the thus calculated each average value so as to decide that the bill having the least totaled value is the discriminated note.

Claim 5

A bill discriminating apparatus according to Claim 1, wherein the data arithmetic means subjects the segmented scale data to data processing in each block area to thereby generate histogram data while the standard data stroage means holds each histogram data as each standard arithmetic data in every bill and the bill decision means collates the thus generated histogram data with the standard histogram data and subjects the collated data to an arithmetic process so as to decide the denomination of the bill.

Claim 6

A bill discriminating apparatus according to Claim 1, wherein the data arithmetic means integrates the segmented scale data in every block area to thereby obtain ingegral data while the standard data storage means holds each standard integral data as each arithmetic data and the bill decision means totals an absolute value of the difference between each standard integral data for every bill and the thus obtained integral data so as to decide that the bill having the least totaled value is the discriminated bill.

Claim 7

A bill discriminating apparatus according to Claim 1, wherein the data arithmetic means integrates the segmented scale data in every block area to obtain integral data while the standard data storage means holds weight data for every bill and the bill decision means subjects both the weight data and the thus obtained integral data to the arithmetic process and totals the operated value in every block area so as to decide that the bill having the totaled maximum value is the discriminated bill.

Claim 8

A bill discriminating apparatus according to Claim 1, wherein the data segmenting means segments the bill scale data into 16 block areas.

Claim 9

A bill discriminating apparatus comprising a sensor for reading all the printed patterns of discriminated bill and a data storage memory for storing discriminated data including bill scale data detected by the sensor characterized in that the bill discriminating apparatus further comprises: bill scale data selection means for retrieving the bill scale data from the discriminated data and fetching the retrieved bill scale data; data segmenting means for segmenting the thus selected bill scale data into a plurality of block areas; data arithmetic means for subjecting the segmented scale data to an operation process in each block area; first standard data storage means for storing each standard arithmetic data therein for each predetermined note; bill decision means for reading each standard operation data from the first standard data storage means and collating the operation data which was subjected to arithmetic process in each block area with each standard arithmetic data; histogram data generating means for subjecting the segmented scale data in every block area to data processing so as to generate histogram data; second standard data storage means for storing predetermined histogram data therein for every note; and bill authenticity decision means for reading the standard histogram data from the second standard storage means on the basis of a bill denomination information which is decided by the bill decision means and collating the histogram data in every block area with the standard histogram data so as to decide the authenticity of the note.

Claim 10

A bill discriminating apparatus according to Claim 9, wherein the bill authenticity decision means includes data compression means for compressing the histogram data.

Claim 11

A bill discriminating apparatus comprising a sensor for reading all the printed patterns of discriminated bill and a data storage memory for storing discriminated data including bill scale data detected by the sensor characterized in that the bill discriminating apparatus further comprises: bill scale data selection means for retrieving the bill scale data from the discriminated data and fetching the retrieved bill scale data; data segmenting means for segmenting the thus selected bill scale data into a plurality of block areas; data operation means for subjecting the segmented scale data to an arithmetic process in each block area; first standard data storage means for storing each standard operation data therein for each predetermined note; bill decision means for reading each standard arithmetic data from the first standard data storage means and collating the arithmetic data which was subjected to arithmetic process in each block area with each standard arithmetic data; synthesized scanning line operation means for synthesizing one scanning line data in a plurality of scanning line data so as to obtain sysnthesized scanning line data; second standard storage means for storing predetermined storing standard synthesized scanning line data for every note; and bill authenticity decision means for reading standard synthesized scanning line data on the basis of a bill denomination information which is decided by the bill decision mesns from the second standard data storage means and collating the synthesized scanning data calculated by the synthesized scannng line operation means with the standard synthesized scanning line data so as to decide the authenticity of the bill.

Claim 12

A bill discriminating apparatus according to Claim 1, wherein the synthesized scanning line operation means synthesizes a plurality of adjoining scanning line data.
