Abstract
The drive arrangement of a currency validator includes a drive roller release mechanism that provides release of the rollers from a drive shaft. This release allows a banknote to be forcibly withdrawn without damaging a drive train or the drive roller. The drive roller is supported on and rotatable about a drive shaft. The drive shaft includes an intermediary drive ring secured on the shaft and in engagement with the drive roller. A spring bias urges the drive roller to engage and rotate with rotation of the shaft and the intermediary drive ring secured on the shaft. When necessary the drive roller can rotate relative to the shaft by overcoming the spring bias.
