Paper currency discriminating device

Abstract

A paper currency discriminating device which is improved to prevent the illegal extraction of paper currency more reliably. An impeller 10 associated in the rotating direction of timing belts 14 for transferring the paper currency is so disposed at the exit of a paper currency transfer passage 6 as to protrude upward over the paper currency transfer face of an upper transfer plate 3. Moreover, the impeller 10 at the time of introducing the paper currency is inhibited from backward rotation to prevent any illegal extraction of the paper currency once introduced. At the same time, a decision signal is outputted after it is detected by a passage detection sensor P3 that the trailing end of the paper currency being transferred reaches the impeller 10 over an extraction preventing lever 33. As a result, it is possible to prevent the illegal use of the paper currency by the extraction which is done before the end of the introduction. Moreover, the illegal recovery of the paper currency by abusing the opening action of the paper currency transfer passage 6 is prevented by preventing any additional insertion of paper currency by closing the paper currency transfer passage 6 with a shutter member 24 till the introduction of the paper currency is ended.
