Abstract:
1. A container holder of a liquid consuming apparatus to which substantially rectangular parallelepiped liquid containers can be detachably mounted, the liquid containers each having a front end surface with a substantially rectangular shape including a first short edge, a second short edge, a first long edge, and a second long edge, a rear end surface opposite to the front end surface, a first side surface intersecting the first short edge, a circuit board disposed on the first side surface, an electrode disposed on the circuit board, a second side surface intersecting the second short edge, a container fixation structure disposed on the second side surface, a third side surface intersecting the first long edge, a fourth side surface intersecting the second long edge, the third and the fourth side surfaces being the largest surfaces, a notch formed at the corner intersecting at least two of the first to fourth side surfaces, a liquid containing chamber for containing a liquid, a pressurizing chamber for pressurizing the liquid containing chamber by introducing a pressurization fluid, and a liquid supply port for supplying the liquid to a liquid ejecting head, the container holder comprising: a support board adapted to support the second side surface of the plurality of the liquid containers; a plurality of guide rails protruding on the support board along the insertion direction of the liquid container, each guide rail having a shape corresponding to the shape of a notch of a respective liquid container; a plurality of container mounting portions partitioned by the plurality of guide rails; an opposite surface, opposite to the support board and adapted to face the first side surface of the plurality of the liquid containers; a plurality of apparatus terminals disposed on the opposite surface, each of the plurality of apparatus terminals provided on the opposite surface of each of the cartridge slots, and each of the apparatus terminals adapted to come in contact with the electrodes of each of the liquid containers; a plurality of apparatus fixation structures, each of the plurality of the apparatus fixation structures provided on the lower side of the each of the cartridge slots, and each of the apparatus fixation structure adapted to releasably regulate a movement of the liquid container in a direction opposite to an insertion direction thereof in cooperation with the container fixation structure of each of the liquid containers; a pair of support sidewalls adapted to face pair of outermost largest surfaces of the plurality of liquid containers mounted on the container mounting portions.
