ABSTRACT:
An ink path through which ink is delivered from an ink source to a printhead unit includes an ink tube and a joint. The ink tube has a first layer formed of a material with low vapor and gas permeability and a second layer radially thicker than the first layer and formed of a flexible material. The joint has a maximum-diameter portion whose outer diameter is larger than an inner diameter of the ink tube. The joint is inserted into the ink tube. Further, a locking member is fitted over the ink tube. The locking member has an inner-diameter portion whose inner diameter is smaller than an outer diameter of a connection between the maximum-diameter portion of the joint and the ink tube.
