When the recording medium is stored in the storage cartridge 110 and the suction pad 62a sucks the recording medium, the suction pad 62a is blocked by the recording medium 200, and the suction pressure rapidly increases.

  On the other hand, when the storage cartridge 110 becomes empty and the suction pad 62a directly sucks the bottom plate 112, a groove 112c and a hole 112d provided in the bottom plate 112 are formed toward the surface 112e to which the suction pad 62a sucks. Air flows in the direction of arrow D shown in FIG. 5 through the passage, and the air is sucked into the adsorption pad 62a. For this reason, even if the suction pad 62a sucks the bottom plate 112, the suction pressure of the suction pad 62a is almost kept at the predetermined suction pressure.

  In the present embodiment, the suction pressure of the suction pad 62a is monitored by a pressure sensor (not shown), and no increase in suction pressure is recognized even after a predetermined time has passed since the suction pad 62a started to fall into the storage cartridge 110. Sometimes it is determined that the storage cartridge 110 is empty. In the present embodiment, detection of the state that the storage cartridge is empty is executed in this way.
