ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for checking the condition of documents such as bank notes.
Constant usage of paper documents such as bank notes causes them to wear. Documents need to be of a sufficiently good condition to be mechanically handled or read by automated means. Very worn, limp, torn, incomplete or folded documents can cause errors in reading them and/or cause the mechanisms handling them to jam. Known self-service deposit terminals contain such document handling mechanisms.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a simple apparatus for checking the condition of documents.
According to the present invention there is provided an apparatus for checking the condition of documents, characterized by transport means for transporting documents individually past brush means the bristles of which are arranged to make contact with at least one face of each document, vibration sensor means arranged to produce an output dependent on the vibration of said bristles brushing against a document, and condition determining means connected to said vibration sensing means and arranged to make a determination of the condition of a document contacted by said brush means on the basis of the output of said vibration sensor means.
