A device for discharging a stack of flat objects standing on their narrow faces, in particular a stack of mail items, includes a stack holder with a base for holding the objects and a supporting element supporting the stack. The supporting element is a platform-type wall, preferably with recesses, into which a further supporting element with inverted recesses can pass. The stack holder can be pivoted about an axis of rotation and its base has a conveyor. This ensures that stack quality is preserved during the complete discharging process. The ergonomics of the device are also improved for its operator.
