Title: Document sensor for currency recycling automated banking machine
Inventor: MODI AL
IPC: G07D11/00
Filed: 1998-11-19
Abstract: The invention relates to an automated banking machine that identifies and stores documents such as currency notes, deposited by a user, and dispenses such documents to users. Conventional banking machines use document thickness sensors for detecting double feeds by sensing the transmissivity of light through a small area of the note.  Conditions such as marking, staining or bleaching of the notes can make sensing unreliable. The invention overcomes this by the use of a sheet thickness detector (810) that senses light transmissivity over a relatively large width of the note. The thickness detector includes a radiation source (822) from which radiation is directed by a radiation guide (824) to a generally linear elongated radiation outlet (826) which extends transversely to the sheet path. A receiver (814) includes a radiation sensitive element (830) which is also transversely elongated relative to the sheet path. Sheets passing between the emitter and receiver cause variations in the amount of radiation reaching the receiver.
