Abstract
An apparatus for testing for particulate contaminants in deposited mail-like articles includes an enclosure adapted for receiving deposited mail-like articles, a squeezing mechanism located within the enclosure and adapted for pressuring opposite flat sides of said deposited mail-like articles for expelling air along with any particulate matter from said deposited mail-like articles and into the enclosure, and a sensing apparatus operatively coupled to the enclosure and adapted for determining the presence of particulate contaminants in air expelled from the deposited mail-like articles. The apparatus may be embodied in a depository of an automated teller machine.
