A drive linkage arrangement for a bill validator maintains driver rollers in synchronization as a bill is driven along a predetermined path for scanning thereof. The drive linkage is a parallelogram linkage with three nodes of the linkage driving drive rollers. The fourth node of the linkage is connected to the output of a gear box driven by a drive motor. The linkage is a cost effective reliable approach for distributing power of a single motor to the spaced drive rollers. |
