Medium discharge device, medium processing device, and recording system

A medium discharge device comprising:

• an intermediate tray having an alignment section that aligns a rear end of a medium and on which the medium aligned by the alignment section is placed;
• a pair of medium support sections that
• face each other in a width direction intersecting with a discharge direction of a medium discharged from the intermediate tray,
• are configured to support a front end, with respect to the discharge direction, of the medium placed on the intermediate tray, and
• are configured to be openable and closable by moving in opposite directions from each other in the width direction;
• a discharge section configured to discharge the medium from the intermediate tray to the medium support section;
• a stacking section provided below the pair of medium support sections and on which the medium dropped from the pair of medium support sections is stacked;
• and
• a curve imparting section that by contacting the medium discharged by the discharge unit, applies a curve to the medium, wherein
• an upstream end of the pair of medium support sections in the discharge direction is provided lower than a downstream end of the intermediate tray in the discharge direction,
• the curve imparting section imparts, to the medium, a curve that warps in the medium width direction,
• the discharge section has a discharge roller pair that nips and discharges the medium,
• the discharge roller pair includes a driven roller configured to contact the medium from above the medium supported by the intermediate tray and a drive roller configured to contact the medium from below the medium supported by the intermediate tray,
• the curve imparting section is configured to contact the medium from above the medium supported by the intermediate tray, and
• the curve imparting section is configured by a rotating body that rotates coaxially with the driven roller.

• a pair of medium support sections that
• face each other in a width direction intersecting with a discharge direction of a medium discharged from the intermediate tray,
• are configured to support a front end, with respect to the discharge direction, of the medium placed on the intermediate tray, and
• are configured to be openable and closable by moving in opposite directions from each other in the width direction;
• a discharge section configured to discharge the medium from the intermediate tray to the medium support section;
• a stacking section provided below the pair of medium support sections and on which the medium dropped from the pair of medium support sections is stacked;
• a guide member configured to switch between a guide state for guiding the medium to the alignment unit and a retracted state farther away from the intermediate tray than in the guide state;
• and
• a curve imparting section that by contacting the medium discharged by the discharge unit, applies a curve to the medium, wherein
• an upstream end of the pair of medium support sections in the discharge direction is provided lower than a downstream end of the intermediate tray in the discharge direction,
• the curve imparting section imparts, to the medium, a curve that warps in the medium width direction,
• the curve imparting section is provided so as to engage with the guide member,
• when the guide member is in the retracted state, the curve imparting section is in a first state, and
• when the guide member is in the guide state, the curve imparting section is in a second state in which the curve imparting section is more retracted from the intermediate tray than in the first state.
