Abstract
An apparatus for moving a document 10 along a track 12 comprises conductive driven members 16 and idler member 18 together with circuit 54 for detecting electrical continuity there-between. Presence of an insulating document 10 between the members 16, 18 breaks an electrical circuit. The driven member 16 has a motor 36 controlled by a motor control switch 38b which can receive a control signal 40 to switch the motor on and another control signal 42 to switch the motor off. Space along a track, drive sets 14 cooperate to move a document along the track 12 with only 2 drive sets switched on at any time and without need for central control.
