A sheet stacking portion is provided in a sheet storing portion in which sheets are stored. The sheet stacking portion is suspended by a wire which is wound up and wound off. The sheet stacking portion is raised and lowered by winding up and winding off the wire. Then, when the wire is in a slack state, a fixing portion fixes the sheet stacking portion to the sheet storing portion. When the wire is in a tensioned state, the fixing of the sheet stacking portion is released. |
