Liquid ejecting device including head unit, and mounting unit having positioning part for positioning head unit relative to mounting unit

A liquid ejecting device comprising:

• a head unit comprising:
• a first channel member formed with a first channel having:
• an ejection hole;
• and
• a first communication port in communication with the ejection hole to allow fluid to flow therebetween;
• and
• a mounting unit which the head unit is mountable on and removable from, the mounting unit supporting the head unit in a state where the head unit is mounted on the mounting unit, the mounting unit comprising:
• a second channel member formed with a second channel having:
• a second communication port;
• and
• a positioning part,
• wherein the liquid ejecting device is switchable between:
• a first state in which the head unit is not positioned relative to the mounting unit, and the first communication port and the second communication port are not in communication with each other;
• and
• a second state in which the head unit is positioned relative to the mounting unit with the positioning part, and the first communication port and the second communication port are in communication with each other to allow fluid to flow from the second communication port through the first communication port to the ejection hole, and
• wherein the liquid ejecting device is shifted from the first state to the second state as the second channel member and the positioning part are moved relative to the head unit.
