Medium conveying apparatus

A medium conveying apparatus comprising:

• a main body in which a conveying path for conveying a medium is formed;
• a placement board that is supported by the main body so as to be rotatable about a rotation axis such that the placement board moves between a storage position and an unfolding position via a midway position, and on which the medium is placed;
• an extension member that is movably supported by the placement board so as to move between a contraction position and an expansion position;
• a lever that is movably supported by the placement board so as to move between a protrusion position and a pushed position;
• and
• a mechanism that converts a motion of the lever to a motion of the extension member such that
• the extension member is located at the contraction position when the lever is located at the protrusion position, and
• the extension member is located at the expansion position when the lever is located at the pushed position, wherein
• the lever is away from an abutting portion fixed to the main body when the placement board is located in a separation section between the storage position and the midway position, and
• the lever comes into contact with the abutting portion and moves toward the pushed position when the placement board is located in a contact section between the unfolding position and the midway position and when the placement board moves toward the unfolding position.
