Abstract

A transport device includes a transporting belt including an outer peripheral surface where a medium is placeable, the transporting belt being configured to transport the medium, a wiper blade including a tip portion configured to come into contact with the outer peripheral surface, and a base end portion located on an opposite side of the tip portion in an intersecting direction intersecting with the outer peripheral surface, the wiper blade being configured to wipe the outer peripheral surface, a contact portion made of resin and configured to support the base end portion by coming into contact with the base end portion, and a plurality of pressing units provided side by side in a width direction of the transporting belt, the plurality of pressing units being configured to press the base end portion via the contact portion.

First claim

What is claimed is:

1. A transport device comprising:
a transporting belt including an outer peripheral surface where a medium is placeable, the transporting belt being configured to transport the medium;
a wiper blade including a tip portion configured to come into contact with the outer peripheral surface, and a base end portion located on an opposite side of the tip portion in an intersecting direction intersecting with the outer peripheral surface, the wiper blade being configured to wipe the outer peripheral surface;
a contact portion made of resin and configured to support the base end portion by coming into contact with the base end portion; and
a plurality of pressing units provided side by side in a width direction of the transporting belt, the plurality of pressing units being configured to press the base end portion via the contact portion.

2. The transport device according to claim 1 , further comprising:
a plurality of switching units configured to perform switching from one of a first state and a second state to the other, the first state being a state in which the contact portion is displaced by being pressed by the plurality of pressing units, the second state being a state in which the displacement is more restricted than in the first state.

3. The transport device according to claim 2 , comprising:
a support portion including a support face configured to support the contact portion in a displaceable manner, wherein
the plurality of switching units include a screw including a shaft portion provided with a spiral groove, and a head portion having an outer dimension larger than an outer dimension of the shaft portion,
the support portion is provided with a screw hole extending in a direction intersecting with the support face, the screw hole being screwed with the spiral groove of the shaft portion, and
the contact portion is provided with a hole extending in the direction intersecting with the support face, and a dimension of the hole in the width direction when viewed in plan view from the direction intersecting with the support face is equal to or larger than the outer dimension of the shaft portion and smaller than the outer dimension of the head portion.

4. The transport device according to claim 1 , comprising:
a support portion including a support face configured to support the contact portion in a displaceable manner, wherein
the plurality of pressing units include a second screw including a second shaft portion provided with a second spiral groove, and a second head portion having an outer dimension larger than an outer dimension of the second shaft portion, and
the support portion is provided with an upright portion extending in a direction intersecting with the support face, and
the upright portion is provided with a second screw hole screwed with the second spiral groove of the second shaft portion.

5. The transport device according to claim 1 , wherein
when, in the contact portion, a plurality of positions pressed by the plurality of pressing units are defined as a plurality of pressed positions, and a position between the plurality of pressed positions is defined as a non-pressed position, rigidity of the contact portion at the non-pressed position is smaller than rigidity of the contact portion at the pressed positions.

6. A liquid ejecting device comprising:
an ejecting unit configured to eject a liquid to a medium;
a transporting belt including an outer peripheral surface where a medium is placeable, the transporting belt being configured to transport the medium;
a wiper blade including a tip portion configured to come into contact with the outer peripheral surface, and a base end portion located on an opposite side of the tip portion in an intersecting direction intersecting with the outer peripheral surface, the wiper blade being configured to wipe the outer peripheral surface;
a contact portion made of resin and configured to support the base end portion by coming into contact with the base end portion; and
a plurality of pressing units provided side by side in a width direction of the transporting belt, the plurality of pressing units being configured to press the base end portion via the contact portion.

7. The liquid ejecting device according to claim 6 , further comprising:
a plurality of switching units configured to perform switching from one of a first state and a second state to the other, the first state being a state in which the contact portion is displaced by being pressed by the plurality of pressing units, the second state being a state in which the displacement is more restricted than in the first state.
