PAPER CURRENCY VALIDATOR Abstract of the Disclosure: Longitudinally- spaced and laterally-spaced sensors are used to sense part of the upper half and part of the lower half of each inserted bill -- to prevent acceptance of a sheet of paper bearing just the upper half or just the lower half of an authentic bill. One sensor engages and senses part of the leading half, and the other sensor engages and senses part of the trailing half, of each inserted bill -- to prevent acceptance of a sheet of paper bearing just the leading half or just the trailing half of an authentic bill. In addition, the longitudinal spacing enables those sensors to provide four signals which are spaced apart in time; and thus makes it possible to use two sensors to provide four time-spaced signals. The two sensors of the paper currency validator are connected in series so one ampli- fier can receive and amplify the signals from both of those sensors. The sensors engage and sense the border on each inserted authentic bill before they engage and sense the longitudinally-spaced and laterally-spaced areas on that bill -- thereby making it possible to re- ject any bill which does not have a border.
