Medium ejection apparatus including ejection tray formed with recessed part and beam part

A medium ejection apparatus comprising:

• a housing;
• an ejection roller to eject a medium in a medium ejection direction;
• and
• an ejection tray attached to the housing to be able to rotate and having a first surface and a second surface, formed at a back side of the first surface, the ejection tray configured to stack the medium ejected by the ejection roller;
• wherein
• the first surface is formed with a first recessed part extending in the medium ejection direction and a first beam part extending in the medium ejection direction and protruding from the first recessed part, wherein
• the second surface is formed with a second recessed part extending in the medium ejection direction and a second beam part extending in the medium ejection direction and protruding from the second recessed part, and wherein
• the first beam part is formed so that a part at an upstream side from a predetermined position in the medium ejection direction is sunken down further than a part at a downstream side from the predetermined position in the medium ejection direction in a state enabling the medium to be stacked on the first surface.
