Abstract

Provided are a transporting belt including a support face configured to support a medium, the transporting belt being configured to transport the medium; a wiper configured to wipe the support face; an attachment portion to which the wiper is attached; and a holding portion configured to switch between a pressing state in which the wiper is pressed against the attachment portion and a release state in which the pressure of the wiper against the attachment portion is released, in which the wiper includes a base portion attached to the attachment portion, either one of the base portion and the attachment portion includes at least one pin, and the other one includes a hole through which the at least one pine is inserted.

First claim

What is claimed is:

1. A transport device, comprising:
a transporting belt including a support face configured to support a medium, the transporting belt being configured to transport the medium;
a wiper configured to wipe the support face;
an attachment portion to which the wiper is attached; and
a holding portion configured to switch between a pressing state in which the wiper is pressed against the attachment portion and a release state in which the pressure of the wiper against the attachment portion is released, wherein
the wiper includes a base portion attached to the attachment portion,
either one of the base portion and the attachment portion includes at least one pin, the other one includes a hole through which the at least one pin is inserted, and
a portion of the holding portion that is in the contact with the base portion includes a protrusion and a recession, the protrusion separating the holding portion from contact with the recession.

2. The transport device according to claim 1 , wherein
the pin includes a first pin and a second pin configured to be inserted through the hole that is a single hole,
the first pin and the second pin are provided at the attachment portion,
the hole is provided in the base portion, and
in a state where the first pin and the second pin are inserted through the hole, the first pin and the second pin press an inner wall that constitutes the hole, in directions differing from each other.

3. The transport device according to claim 1 , wherein
the holding portion includes:
a slide portion configured to slidably move relative to the attachment portion; and
a protruding portion provided at a portion of the slide portion that is opposed to the base portion, wherein,
as the slide portion slidably moves, the protruding portion moves to a position for pressing the base portion against the attachment portion.

4. The transport device according to claim 3 , wherein, in a state where the slide portion is slidably moved to the maximum extent relative to the attachment portion, the slide portion is locked at the attachment portion.

5. The transport device according to claim 3 , comprising:
a storage unit configured to store a liquid used to clean the support face, wherein
the attachment portion is supported inside the storage unit, and
the slide portion includes a cover portion with which the at least one pin and the hole are covered.

6. The transport device according to claim 5 , wherein
the cover includes
a first opening that the wiper enters when slidably moving relative to the attachment portion, and
a second opening disposed at an opposite side from the first opening in a direction of the slide movement relative to the attachment portion, wherein
the second opening is disposed below the first opening in a gravitational direction.

7. The transport device according to claim 1 , wherein
the at least one pin includes a taper portion.
