  • Patent number: 7520603
    Abstract: In an inkjet printer including first to n-th paper storages, such as a magazine type storage or a cassette type storage, and associated first to n-th upstream transport lines (where n is a natural number larger than 1), a paper carrier (switchback unit) is provided which has a roller pair reciprocable between any of first to n-th receive points corresponding to the downstream ends of the first to n-th upstream transport lines, respectively, and a forwarding point corresponding to the upstream end of a downstream transport line by means of a moving mechanism. The paper carrier is configured so that the roller pair receives and grips, at one of the first to n-th receive points, a sheet of printing paper transported from the associated upstream transport line, the moving mechanism moves the roller pair from the receive point to the forwarding point and the gripped sheet of printing paper is forwarded at the forwarding point to the downstream transport line.
