Abstract
A tray member incorporated in a tray device is movable vertically in parallel in accordance with the thickness of sheets fed from a sheet handling system, so as to easily attach the tray device to the sheet handling system such as an image forming device, copying machine, printer and sheet post-processing apparatus for automatically stapling sheets. A driving mechanism for vertically moving the tray member is simple in structure, so that it can be incorporated compactly within the tray member. A low-power driving mechanism suffices for vertically moving only the tray member, so that the driving mechanism can be efficiently operated even with small power. The tray device has all the component elements including the driving mechanism built-in, so as to impose little structural restrictions on the sheet handling system to which the tray device is united.
