Bill counting machine

摘要

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.
