ABSTRACT:
In a printer provided with a sheet reversing mechanism, and which can perform printing on both faces of a sheet by a common print head, reduction of the number of parts, prevention of a transport failure, and the like are realized by reversing the sheet while the sheet is clamped by one transporting roller pair. The printer includes a first sheet path. A print head is disposed on the first sheet path to perform printing on a recording sheet. A transporting roller pair includes a first roller and a second roller, adapted to transport the recording sheet in a first direction approaching the print head (toward an outlet) and a second direction opposed to the first direction (toward an inlet). A second sheet path is branched from the first sheet path at a branching position shifted from the first roller in the second direction, extending along an outer periphery of the first roller, and joined to the first sheet path at a joining position between the transporting roller pair and the print head. A path switcher is disposed in the vicinity of the branching position so as to be placed at a first position for selecting the first sheet path and a second position for selecting the second sheet path, so that a path of the recording sheet transported in the second direction is switched to the first sheet path or the second sheet path.
