Abstract
A duplex printer with a small, compact conveyance path has a medium supply path and a medium inverting path that merge into a middle conveyance path at a junction. The middle conveyance path goes to a path switching unit connecting a main conveyance path and the inverting path. A flap, which is a path switching member, is disposed in the path switching unit. A middle conveyance roller pair, having a middle conveyance roller and a nipping portion, conveys the medium (e.g. paper) through the middle conveyance path. The portion of the middle conveyance path from at least the junction to the nipping portion is a conveyance path portion defined by the roller surface of the middle conveyance roller. The paper fed to the middle conveyance path is guided by the middle conveyance roller from the junction to the nipping portion of the middle conveyance roller pair.
