Abstract: A liquid supply unit includes a first wall part to a seventh wall part. The first wall part includes a liquid supply part and an outer peripheral wall surrounding the liquid supply part and protruding in a direction from the second wall part toward the first wall part so as to come into contact with a sealing member of a carriage. The liquid supply part has a filter for supplying liquid to a liquid introduction part upon coming into contact with the liquid introduction part. A distance between the third wall part and the fourth wall part is larger than a distance between the fifth wall part and the sixth wall part. In a plan view in a direction from the first wall part toward the second wall part, a length of the outer peripheral wall in a first direction from the third wall part toward the fourth wall part is larger than a length in a second direction from the fifth wall part toward the sixth wall part. In a state of the liquid supply unit mounted on the carriage, the first direction is set along a moving direction of the carriage.

Abstract: A further improvement in convenience is desired in conventional liquid ejecting systems. A liquid supplying unit is mountable to a carriage that has a first projection, a second projection and a liquid introduction needle. The unit includes six wall portions. The first wall portion is provided with a liquid supplying portion connectable to a liquid introduction needle, a first recess portion adapted to receive the first projection, and a second recess portion adapted to receive the second projection. In a planar view of the first wall portion, the liquid supplying portion is positioned closer to the fifth wall portion than to the sixth wall portion, and when the first wall portion is equally divided into a first region, a second region and a third region, the first recess portion is positioned in the first region, and the second recess portion is positioned in the third region.

Abstract: A tank unit includes two or more liquid accommodating containers disposed in a row. Each of the liquid accommodating containers includes a main body having a concave shape defining a side opening and a film that blocks the side opening. The main body and the film at least partially define a liquid accommodating chamber for accommodating a liquid. The main body includes a facing wall that faces the film across the liquid accommodating chamber and has a wall larger than the side opening. The liquid accommodating containers are disposed such that the film of at least one of the liquid accommodating containers is covered by the facing wall of an adjacent one of the liquid accommodating containers.
