Abstract
Ratchets which regulate a rotation of either a reeling-out roller around which one end of a long wiping member which wipes ink attached to a recording head which ejects ink is wound, or a winding-up roller around which the other end of the wiping member is wound to which tension is applied due to a friction force which acts on the wiping member when performing wiping are provided.

A wiper cassette comprising:
- a housing;
- a wiping member which wipes a liquid adhered to a liquid ejecting head which ejects the liquid;
- a feed roller around which an end of the wiping member is wound in a longitudinal direction;
- and
- a winding roller around which other end of the wiping member is wound in the longitudinal direction,
- wherein the wiper cassette is mounted so as to be freely detachable and attachable into a wiper holder,
- wherein the wiper cassette further comprises:
- a winding gear supported by the winding roller at an outside of the housing;
- and
- a rotation gear which rotates corresponding to movement of the wiping member, and
- wherein the rotation gear is positioned below the winding gear in a mounted state in which the wiper cassette is mounted into the wiper holder.
A wiper unit comprising a wiper cassette and a wiper holder, the wiper cassette comprising:
- a housing;
- a wiping member which wipes a liquid adhered to a liquid ejecting head which ejects the liquid;
- a feed roller around which an end of the wiping member is wound in a longitudinal direction;
- and
- a winding roller around which other end of the wiping member is wound in the longitudinal direction,
- wherein the wiper cassette is mounted so as to be freely detachable and attachable into a wiper holder,
- wherein the wiper cassette further comprises
- a winding gear supported by the winding roller at an outside of the housing;
- and
- a rotation gear which rotates corresponding to movement of the wiping member, and
- wherein the rotation gear is positioned below the winding gear in a mounted state in which the wiper cassette is mounted into the wiper holder.
A liquid ejecting apparatus comprising a wiper unit and a liquid ejecting head, the wiper unit comprising a wiper cassette and a wiper holder, the wiper cassette comprising:
- a housing;
- a wiping member which wipes a liquid adhered to a liquid ejecting head which ejects the liquid;
- a feed roller around which an end of the wiping member is wound in a longitudinal direction;
- and
- a winding roller around which other end of the wiping member is wound in the longitudinal direction,
- wherein the wiper cassette is mounted so as to be freely detachable and attachable into a wiper holder,
- wherein the wiper cassette further comprises
- a winding gear supported by the winding roller at an outside of the housing;
- and
- a rotation gear which rotates corresponding to movement of the wiping member, and
