Abstract: Apparatus for counterbalancing the movement of a platen cover or document handler between a first closed position and a second open position. The counterbalancing apparatus comprises a gas spring and a tension spring. The tension spring is arranged to increasingly counter the force exerted by the gas spring as the platen cover is moved from the first to the second position. This compensates for the reduced force exerted by the platen cover as it is opened. The platen cover in the second position preferably has moved past vertical and the tension spring is effective to counter the force exerted by the cover between vertical and the second position.
