Abstract
[Object] To reduce the time required to transport a cut sheet and perform printing at a high speed. [Solution] A duplex printer 10 includes a printing unit 12A, a cut sheet feeder 25, and a guide transport path 24. A reversing mechanism 20 that reverses a cut sheet 1 returned from the printing unit 12A is connected to the guide transport path 24 via a switcher 61. A stopper 62 that stops the cut sheet 1 is provided in a part of the guide transport path 24 on the upstream side of the switcher 61. A discharge path 65 branches off from the stopper 62 of the guide transport path 24.
Claims16
A duplex printer comprising:
- a printing unit;
- a cut sheet feeder that stores a cut sheet on both surfaces of which printing is to be performed and that supplies the cut sheet to the printing unit;
- and
- a guide transport path that transports the cut sheet from the cut sheet feeder to the printing unit,
- wherein a reversing mechanism that reverses the cut sheet returned from the printing unit is switchably connected to the guide transport path via a switcher, and the reversing mechanism reverses the cut sheet whose one surface is facing the printing unit so that the other surface of the cut sheet faces the printing unit,
- wherein a stopper that stops the cut sheet supplied from the cut sheet feeder is provided in a part of the guide transport path on an upstream side of the switcher in a transport direction, and a discharge path that discharges the cut sheet returned from the printing unit is connected via a branching portion to a part of the guide transport path on a downstream side of the stopper in the transport direction, and
- wherein the reversing mechanism is disposed directly below the switcher of the guide transport path.
