The invention provides a delivery system and layered stacking device for paper packages. The layered stacking device comprises a upper layer mechanism, a lower layer mechanism, and a pushing mechanism. The upper layer mechanism protrudes to an outlet of a delivery device to receive at least two paper packages. The paper packages will be stacked and neatly arranged on the upper layer mechanism. When the lower layer mechanism is raised to a first height and therefore close to the outlet, the upper layer mechanism will be withdrawn from the outlet of the delivery device, thereby the lower layer mechanism will receive the stacked paper packages that are dropped from the upper layer mechanism. Afterwards, when the lower layer mechanism is fallen to a second height, the pushing mechanism will push the stacked paper packages on the lower layer mechanism to a feeding device next the lower layer mechanism.

A sheet discharging apparatus includes a first detecting portion provided in an apparatus body and configured to detect a move of a movable member in a state where a movable tray is at an upper limit position in a moving direction of the movable tray, wherein a detection result of the first detecting portion changes depending on a position of the movable tray in the moving direction. In addition, a second detecting portion detects the position of the movable tray in the moving direction, and a control portion, in a case where the second detecting portion detects that the movable tray is at the upper limit position, determines whether a sheet is present on the movable tray based on the detection result of the first detecting portion. When the second detecting portion does not detect that the movable tray is at the upper limit position, the control portion determines that a sheet is present on the movable tray regardless of the detection result of the first detecting portion.

In an example, a print media transport apparatus comprises a plurality of pallets having a self-propulsion mechanism, and being to support print media. The pallets may circulate on an endless track comprising a printing zone, a descending zone and an ascending zone. A controller may control the self-propulsion mechanisms of the pallets such that a pallet on the descending zone is at least partially supported by another pallet which is ahead on the track, and a pallet on the ascending zone is at least partially driven by pallet which follows on the track.
