Abstract
A sheet dispenser mechanism ( ) is described. The mechanism includes upper and lower transport guides ( ) for conveying a sheet such as a bank note therebetween, only one of the transport guides ( ) being movable in a plane transverse to the surface of the bank note ( ). A piezoelectric sensor ( ) is mechanically coupled to the movable transport guide ( ). A detecting circuit ( ) monitors the output from the piezoelectric sensor ( ). When a single bank note ( ) is being transported the movable transport guide ( ) is deflected by the thickness of the bank note and the detecting circuit ( ) detects a first signal. If two sheets are stuck together and transported as a single sheet then the movable transport guide ( ) is deflected by the thickness of the two sheets and the detecting circuit ( ) detects a second signal which is greater than the first signal, thereby indicating that multiple sheets are present.
