Abstract
In apparatus for the separate discharge of flat items from a stack of such items, which apparatus includes a movable support for supporting the stack of items, a withdrawal mechanism mounted to engage the foremost item in the stack and withdraw that item from the stack, a supporting wall manually movable into an initial position for supporting the trailing end of the stack, and a drive system connected to drive the supporting wall toward the withdrawal mechanism under control of the state of a switch actuated in dependence upon the force being exerted by the stack on the withdrawal mechanism, resilient force equalizing elements are provided between the drive system and the supporting wall in drive transmitting relation therebetween, and are constructed and mounted for permitting advancing movement of the supporting wall to lag behind that corresponding to the sum of the drive movements produced by the drive system whenever the pressing force between the supporting wall and the stack exceeds a given value.
