Sheet transport apparatus of printer having scanner unit

A sheet transport apparatus of a printer which has an automatic sheet feeding part, a manual sheet feeding part, a transfer part, an upper cover, a photosensitive medium and a scanner unit, said printer serving to write information on a record sheet through transferring of an image on the photosensitive medium to the record sheet by the transfer part, said record sheet being sent from the automatic sheet feeding part, said scanner unit serving to read image information of an original, said transfer part being provided at an upper portion of the photosensitive medium, said sheet transport apparatus comprising:

• an upper transport path for transporting said record sheet from the automatic sheet feeding part to the transfer part;
• a manual transport path extending from an inlet portion of the manual sheet feeding path, said manual transport path serving to send manually a record sheet from the manual sheet feeding part to the transfer part and joining an intermediate portion of the upper transport path;
• a first transport path where the scanner unit is provided, said first transport path being provided within the upper cover;
• first driving means for transporting a sheet to the scanner unit;
• second driving means for transporting a sheet from the scanner unit tot he first transport path;
• and
• path selection means provided at said intermediate portion of the upper transport path, said path selection means being switched between at a first position and at a second position and being arranged for guiding a sheet passing the manual sheet feeding part to the first transport path leading to the scanner unit when the first position is selected by the path selection means and arranged for guiding a sheet passing the manual sheet feeding part to the upper transport path leading to the transfer part of the printer when the second position is selected by the path selection means, said path selection means selecting the first position when an original passes the manual sheet feeding part and selecting the second position when a record sheet passes the manual sheet feeding part.
