Scanner device and multifunction apparatus with supply path, discharge path, and re-supply path integrally formed together

A multifunction apparatus comprising:

• a printing unit for printing an image on a sheet of paper;
• a scanner device comprising:
• a scanning member to scan an image from a document;
• a supply path to supply a document to the scanning member;
• a discharge path to discharge a document after scanning;
• and
• a re-supply path to re-supply a document fed along the discharge path in a
• direction opposite to a document-feeding direction to the scanning member,
• wherein one-side guide portions of the supply path, the discharge path, and the re-supply path are integrally formed with a main frame by using injection molding,
• wherein the re-supply path, which feeds the document in the direction opposite to the document feeding direction, is defined as a path from a point on the discharge path where the document is discharged to a point on the supply path before the document is supplied to the scanning member.
