PROBLEM TO BE SOLVED: To take out a recording medium smoothly to the end by providing an auxiliary sheet between a storage body and the recording medium and specifying a surface of a storage body side of the auxiliary sheet and the recording medium, a surface of a pressure-contact member and the recording medium, and friction coefficient on a surface of the auxiliary sheet and the storage body to specific conditions. SOLUTION: Stationary friction coefficient on a surface of a paper supply roller 5 and a face 8 of one recording medium 1x isμa, and an auxiliary sheet 3 is provided between the recording medium 1x and a spring plate 4 of a tray. Stationary friction coefficient between the sheet 3 and a surface of the spring plate 4 of the tray isμb to satisfy the relation ofμa>μc andμb>μc when stationary friction coefficient between the sheet 3 and a face 9 of the recording medium 1x isμc. Consequently, it is possible to supply even the last recording medium 1x smoothly.
