Abstract:
1. An ink-jet printer comprising: a head unit for performing recording by ejecting ink onto a recording medium to be fed; an ink cartridge for storing the ink; a heat sink which is in contact with a driver IC that drives the head unit and which cools the driver IC; and a head holder which holds the head unit, the ink cartridge, and the heat sink; wherein the head holder has a bottom wall portion which faces the recording medium with a predetermined spacing therebetween, and the head unit is mounted on one of opposite surfaces of the bottom wall portion so as to oppose to the recording medium while the ink cartridge is removably mounted on the other of the opposite surfaces so as to sandwich the heat sink therebetween, wherein the ink-jet printer further comprises a connecting member for connecting the ink cartridge and the head unit to each other so as to form a flow passage which penetrates the bottom wall portion and the heat sink, the connecting member including a joint portion which is interposed between the ink cartridge and the heat sink and a flow-passage defining portion which defines the flow passage, and wherein the ink cartridge is placed on the heat sink such that the head holder does not directly receive a load from the ink cartridge, but receives the load via the heat sink and the joint portion by placing the heat sink in between and in contact with the head holder and the joint portion.
