Publication number: 20100156025Abstract: By effectively using a sheet feeding mechanism used for feeding a printing medium in a single transporting path for the purpose of another transporting path, a printing apparatus and a printing method that can simplify a configuration and reduce a size are provided. A first transporting path and a second transporting path are selectively used when an image is to be printed on a printing sheet. The first transporting path transports the printing sheet supplied by a sheet feeding roller from a printing sheet loading portion to a printing position. The second transporting path transports the printing sheet located at a position different from the printing sheet loading portion to the printing position. When the printing sheet is to be transported by the second transporting path, the sheet feeding roller is moved onto the second transporting path so as to transport the printing sheet in the second transporting path.Type: ApplicationFiled: December 11, 2009Publication date: June 24, 2010Applicant: CANON KABUSHIKI KAISHAInventor: Motoyuki Taguchi
