Abstract

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. The fourth path transports a sheet from the second bifurcation to the third confluence, and vice versa. The fifth path transports a sheet from the second bifurcation to the second confluence.

An image recording apparatus, comprising:

a sheet feeding section for storing sheets;
an image recording section for recording an image on a side of a sheet;
a sheet output section for receiving a sheet with an image recorded thereon;
a switchback section for transporting a sheet in forward and backward directions;
a first transport path that leads from the sheet feeding section to the sheet output section, through a first confluence, the image recording section, a first bifurcation, and a second confluence in that order;
a second transport path that leads from the first bifurcation down to the switchback section through a second bifurcation and a third bifurcation in that order;
a third transport path that leads from the third bifurcation to the first confluence through a third confluence, the third transport path being positioned between the switchback section and a portion of the first transport path located in the image recording section;
a fourth transport path that leads between the second bifurcation and the third confluence;
and
a fifth transport path that leads from the second bifurcation to the second confluence,
wherein the third transport path is adapted to transport a sheet in forward and backward directions,
the apparatus further comprising a control section configured to perform the steps of;
causing the image recording section to record an image on a side of a sheet;
transporting the sheet from the image recording section to the third transport path, through the first transport path, the first bifurcation, the second transport path, the second bifurcation, the fourth transport path, and the third confluence in that order;
reversing a leading end and a tail end of the sheet in the third transport path;
transporting the sheet from the third transport path to the first transport path through the third confluence, the fourth transport path, the fifth transport path, and the second confluence in that order;
and
outputting the sheet to the sheet output section with the image-recorded side facing downward.
