Abstract
According to aspects of the present disclosure, there is provided a tray swinging mechanism including a document tray. A movable plate of the document tray is configured to be swingable about a tray shaft and extends leftward. A lifter is configured to be swingable about a lifter shaft extending in the front-rear direction at a position different from the tray shaft. On a lower surface of the movable plate, a cam surface configured to contact a tip of the lifter is formed. The cam surface includes a parallel part parallel to an upper surface of the movable plate and a curved part spaced from the upper surface farther toward a right side. According to a shape of the cam surface, each time the lifter is rotated by a particular angle, the tip of the movable plate moves by a particular amount.
