In a sheet storing portion, a sheet tray which supports a sheet and a side regulating plate which moves depending on a sheet size to regulate a side end of the sheet are arranged. A notched portion to make it possible to move the side regulating plate is formed in the sheet tray, and a swingable auxiliary tray which constitutes the same plane as that of a sheet support surface of the sheet tray is arranged in the notched portion to prevent the sheet from being hanged down at the notched portion of the sheet tray. A hole into which the auxiliary tray can be inserted is formed in a side surface of the side regulating plate for the sheet. When the sheet tray moves upward to a predetermined position, the auxiliary tray is designed such that the auxiliary tray is brought into contact with a contact portion formed on an upper end of the hole and is swingably retreated downward, so that a sheet regulating surface of the side regulating plate can be assured.
