Abstract

A detector of the strain-gauge paper money counter for detecting overlapped two sheets of paper money is disclosed. A cantilever sensor connected to single-chip computer is mounted above the detecting wheel driven by motor. A bearing rotable fiexibly mounted on one end of said cantilever sensor elastically presses on said detecting wheel. A photoelectric coupler is matched with a barrier on active axle of detecting wheel, and has an output connected to interrupt input of said single-chip computer. A pair of infrared photoelectric tubes are installed for detecting if paper money exists.

Description

[0001] Field [0002] The invention relates to a banknote double-sheet detection device of a strain measuring type banknote sorting machine, which belongs to the field of banknote sorting machines.
