Medium discharge device and recording apparatus

A medium discharge device comprising:

• a discharge unit that discharges a medium;
• a first medium receiving tray that receives the medium discharged by the discharge unit;
• a second medium receiving tray that is provided above the first medium receiving tray in a vertical direction and receives the medium discharged by the discharge unit;
• a geared rack mechanically connected to the second medium receiving tray;
• and
• a drive gear configured to engage the geared rack to cause the geared rack to move substantially horizontally between an upstream side and a downstream side,
• wherein:
• the first medium receiving tray is fixed at a same position;
• the second medium receiving tray is capable of changing a position between an advance position and a retraction position;
• when the second medium receiving tray is in the advance position, an upstream zone of the second medium receiving tray is advanced to a passing route of the medium being discharged from the discharge unit, such that the medium discharged from the discharge unit is to be received by the second medium receiving tray;
• when the second medium receiving tray is in the retraction position, the upstream zone of the second medium receiving tray is retracted away from the passing route, such that the medium discharged from the discharge unit is to be received by the first medium receiving tray;
• and
• the second medium receiving tray moves at least partially horizontally during a position change between the advance position and the retraction position,
• when the geared rack is moved to the upstream side,
• the second medium receiving tray is in the advance position, and
• an upstream zone of the second medium receiving tray is advanced to a passing route of the medium being discharged from the discharge unit, such that the medium discharged by the discharge unit is to be received by the second medium receiving tray;
• and
• when the geared rack is moved to the downstream side,
• the second medium receiving tray is in the retraction position, and
• the upstream zone of the second medium receiving tray is retracted away from the passing route, such that the medium discharged by the discharge unit is to be received by the first medium receiving tray.
