Sheet conveying apparatus and image reading apparatus

An image reading apparatus comprising:

• a reading part that reads an image on a sheet;
• a first path through which the sheet having the image read by the reading part passes;
• a second path through which the sheet having the image read by the reading part passes
• a guide unit that can move, wherein the guide unit guides the sheet passing through the first path on one side of the guide unit and guides the sheet passing through the second path on the an other side of the guide unit;
• a guide member which forms the second path with the other side of the guide unit, wherein one side of the sheet passing through the second path is guided by the guide member and the other side of the sheet passing through the second path is guided by the guide unit;
• and
• a limit member that limits moving of the guide unit,
• wherein when the guide unit is moving toward the guide member so that a sheet passes through the first path, the limit member limits the moving of the guide unit so as to form an interval, through which the sheet can pass between the guide member and the other side of the guide unit.
