Patent number: 7583926Abstract: An image recording apparatus includes first to fifth transport paths. The first path transports a sheet from a sheet feeding section to a sheet output section through a first confluence, an image recording section, a first bifurcation, and a second confluence in that order. The second path transports a sheet from the first bifurcation down to a switchback section through a second bifurcation and a third bifurcation in that order. The third path transports a sheet from the third bifurcation to the first confluence through a third confluence, and vice versa. The third path is positioned between the switchback section and a portion of the first transport path located in the image recording section.
