A feed conveyor feeds in flat items to a discharge conveyor that discharges the same. A joint upper belt conveyor extends across feed-in and discharge regions and has a lower belt section above the feed and discharge conveyors. An operating mechanism moves a lower belt section of the joint upper belt conveyor between: a first position in which a gap is formed between the lower belt section of the joint upper belt conveyor and the discharge conveyor that prevents the joint upper belt conveyor from making contact with the flat items on the discharge conveyor; and a second position in which the gap between the lower belt section of the joint upper belt conveyor and the discharge conveyor is such that the top of the flat item makes contact with the upper join conveyor belt.
