<p>PURPOSE:To enable expansion of a sheet receiving face according to the sheet size without necessity of securing a storage place for an auxiliary tray as before and without trouble of removing the auxiliary tray in a tray for a sheet using device. CONSTITUTION:A tray body 30 of a sheet supply tray 20 is constituted by a base end side mounting table 31 and a tip end side mounting table 32, and the tip end side mounting table 32 is rotatably connected to the base end side mounting table 31. In the tip end side mounting table 32, a lever-containing recess 32e is formed at its tip end edge 32d, and two rotation fulcrum pins 32f are provided at its center. And each of the rotation fulcrum pins 32f is connected to the base end 35a, and a receiving lever 35 is rotatably contained in the lever-containing recess 32e. Thus, when a sheet S in large size is to be used, the receiving lever 35 is rotated to the sheet-receiving position corresponding to each sheet size to expand a sheet receiving face.</p> |
