Abstract
A liquid ejection apparatus includes at least one ink tank which is ink-refillable from outside, a liquid ejection head that ejects an ink supplied from the ink tank, and a housing that contains the ink tank and the liquid ejection head inside. The at least one ink tank is fixed to a housing wall of at least one surface out of surfaces forming the housing. Moreover, one surface out of surfaces forming the ink tank, which is attached to the housing wall, is either a surface having the largest area of the ink tank or a surface opposed to the surface having the largest area.
Claims19
A liquid ejection apparatus comprising:
- at least one ink tank which is ink-refillable from outside;
- a liquid ejection head configured to eject an ink supplied from the ink tank;
- and
- a housing configured to contain the ink tank and the liquid ejection head inside, wherein
- the at least one ink tank is fixed to a housing wall of at least one surface out of a plurality of surfaces forming the housing, and
- of a plurality of surfaces forming the ink tank, a surface attached to the housing wall is any of a surface having the largest area of the ink tank and a surface opposed to the surface having the largest area.
A liquid ejection apparatus comprising:
- at least one ink tank which is ink-refillable from outside;
- a liquid ejection head configured to eject an ink supplied from the ink tank;
- and
- a housing configured to contain the liquid ejection head inside, wherein
- the liquid ejection apparatus includes a tank attachment unit configured to attach the at least one ink tank to a housing wall of at least one surface out of a plurality of surfaces forming the housing,
