Transport device that transports sheet

A transport device comprising:

• a supply tray that supplies a sheet;
• a casing into which the sheet is supplied from the supply tray;
• and
• a straight path discharge tray to which the sheet is discharged from the supply tray and the casing, through a straight path,
• wherein the casing includes:
• a straight transport route through which the sheet is linearly transported;
• a reversing transport route through which the sheet is transported so as to be reversed, the reversing transport route being branched from the straight transport route;
• and
• an image reading device that reads an image on the sheet being transported through the straight transport route,
• the straight path discharge tray includes:
• a first tray section pivotably attached to the casing;
• and
• a second tray section pivotably attached to the first tray section, and
• the straight path discharge tray is switchable between an open state in which the first tray section and the second tray section form a receiving surface for the sheet, and a closed state in which the first tray section and the second tray section partially cover the casing,
• wherein the transport device further comprises:
• a first fulcrum pivotably connecting the casing and the first tray section;
• and
• a second fulcrum pivotably connecting the first tray section and the second tray section,
• the first tray section comprises:
• closing limiting ribs abutted against an end position on a side of the second fulcrum of the second tray section in the closed state to restrict the second tray section from pivoting toward the casing from the position of the closed state;
• and
• an opening limiting rib abutted against the second tray section in the open state from below to restrict the second tray section from pivoting in the direction away from the casing from the position of the open state.
