In accordance with an embodiment, a sheet processing apparatus comprises a first tray, a second tray, a third tray, a lower supporting plate, a drive section and a control device. The second tray is located at the lower part of the first tray. The third tray is located at a downstream side with respect to the second tray in a sheet conveyance direction. The lower supporting plate can support the sheet from the lower part. The drive section drives the lower supporting plate. The control device controls the drive section to arrange the lower supporting plate at the downstream side with respect to a conveyance starting point of the sheet in the sheet conveyance direction in a case of skipping the first tray and the second tray to convey the sheet to the third tray.

A sheet supporting apparatus includes first and second units. The first unit includes a first housing, first and second lock portions, a first shaft configured to be supported rotatably with respect to the first housing and to turnably support the first lock portion, and a second shaft configured to be supported rotatably with respect to the first housing and to turnably support the second lock portion. The second unit includes a second housing and first and second engagement portions provided in the second housing and configured to engage respectively with the first and second lock portions. The first and second shafts are disposed such that extension lines of rotational axes of the first and second shafts cross with each other in a plan view.

A media tray may include a number of mezzanines to accumulate media as the media is ejected from a printing device and a number of ramps to selectively engage with a leading edge of the media as the media is accumulated based on a plurality of positions of the number of ramps, the number of ramps positionable based on movement of the number of mezzanines. In one example, movement of the number of mezzanines from a first position to a second position may cause the number of ramps to be in a position to selectively engage and disengage with a leading edge of the media.
