Abstract
A medium, of which skew is appropriately corrected, is fed from an intermediate unit to a post processing unit so as to suppress an adverse effect of the skew of the medium in the post processing unit.
Claims20
An intermediate unit comprising:
- a carry-in port through which a medium is transported into the intermediate unit from a printing unit that ejects liquid to print an image on the medium;
- a carry-out port through which the medium is transported to a post processing unit that performs post processing on the medium;
- and
- a transportation path that is disposed between the carry-in port and the carry-out port,
- wherein the transportation path is provided with
- a group of pairs of first transportation rollers that is provided with a plurality of pairs of transportation rollers, each of which includes a driving roller that applies a transportation force in a transportation direction to the medium and a driven roller that is rotated in accordance with the rotation of the driving roller with the medium nipped between the driving roller and the driven roller, and
- a pair of correction rollers that is positioned on the downstream side of the group of pairs of first transportation rollers in the transportation direction and corrects skew of the medium with respect to the transportation direction.

A post processing device comprising:
- a group of pairs of transportation rollers that transports a medium, which is transported into the post processing device from a printing unit that ejects liquid to print an image on the medium, in a transportation direction and is provided with a plurality of pairs of transportation rollers, each of which includes a driving roller that applies a transportation force in a transportation direction to the medium and a driven roller that is rotated in accordance with the rotation of the driving roller with the medium nipped between the driving roller and the driven roller;
- a mounting portion on which the medium is mounted;
- and
- a post processing portion that performs post processing on the medium mounted on the mounting portion,
- wherein a pair of correction rollers that corrects skew of the medium with respect to the transportation direction is provided between the group of pairs of transportation rollers and the mounting portion.
