ABSTRACT:
A sprung wheel 46 for a document drive system comprises an upper elastic member 54, a lower elastic member 52, a separating hub 50 and a rim member 56. Each elastic member 42,54 comprises resilient arms 58 which bear upon the rim member 56 on the inside. As the time member 56 is moved eccentrically from the hub 50, supported on a spindle 48, so the resilient arms exert a restoring force. In the second embodiment, the resilient arms 74 are held on the rim portion 561 as opposed to the hub portion 50. The independence of compression of the upper 54 and lower 52 resilient members commits tilting of the rim portion 56, 561.
