Abstract
Abstract A bill counting machine includes a holder for supporting bills thereon and suction heads for turning over the bills, one at a time, to count them. A projector is provided for emitting a ray of light onto the surface of each bill. A receptor is provided for detecting a ray of light reflected from the surface of the bill and for rectilinearly reading the surface pattern of the bill. The rectilinear reading allow judgments as to the denomination and obverse/reverse side of the bills.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A bill counting machine comprising: a holder for holding a stack of bills, suction means for picking up the bills from said holder and turning over the bills, one at a time, a projector for emitting a ray of light onto the surface of each bill, a receptor for detecting a ray of light reflected from a surface of the bill while the bill is turned over by said suction means and for rectilinearly reading a surface pattern of the bill, and a projection provided on the holder at a side of said holder facing a rear surface of the bills for deflecting the bills outwardly away from said holder, said projection being located on the holder so that the stack of bills are held at a uniform distance and angle relative to the receptor, thereby compensating for rectilinear reading of the surface pattern of the bills to thereby prevent pattern reading errors resulting from a difference in the number of bills on said holder by maintaining constant a detected pattern area of the bills.
Claim 2
Dependent Claim
175 words
A bill counting machine comprising: a holder for holding a stack of bills, suction means for picking up the bills from said holder and turning over the bills, one at a time, a projector for emitting a ray of light onto the surface of each bill, a receptor for detecting a ray of light reflected from a surface of the bill while the bill is turned over by said suction means and for rectilinearly reading a surface pattern of the bill, and a projection provided on the holder at a side of said holder facing a rear surface of the bills for deflecting the bills outwardly away from said holder, said projection being located on the holder so that the stack of bills are held at a uniform distance and angle relative to the receptor, thereby compensating for rectilinear reading of the surface pattern of the bills to thereby prevent pattern reading errors resulting from a difference in the number of bills on said holder by maintaining constant a detected pattern area of the bills.
Claim 3
Dependent Claim
51 words
A machine according to claim 1, wherein a reflective material is provided on the holder at said side facing said rear surface of the bills, said reflective material having substantially the same reflectance as that of the bill for compensating for a deviation in the reflectance in the stack of bills.
Claim 4
Dependent Claim
25 words
A machine according to claim 1, wherein a denomination of the bill is judged by the rectilinear reading of the surface pattern of the bill.
Claim 5
Dependent Claim
26 words
A machine according to claim 1, wherein an obverse/reverse side of the bill is judged by the rectilinear reading of the surface pattern of the bill.
