Droplet ejecting device and printing device

A droplet ejecting device comprising:

• an ejection head configured and arranged to eject liquid droplets onto a substrate;
• a moving body supporting the ejection head, and configured and arranged to move integrally with the ejection head with respect to the substrate;
• a guide part extending in a first direction, the guide part being configured and arranged to guide a relative movement of the moving body in the first direction;
• an attachment part attached to the guide part, supporting the moving body, and configured and arranged to move integrally with the moving body;
• a fixed part fixed to the attachment part separately from the moving body;
• and
• a liquid reservoir provided to the fixed part, and configured and arranged to store the liquid supplied to the ejection head, the liquid reservoir being disposed on an opposite side relative to the moving body in a second direction perpendicular to the first direction and a vertical direction of the droplet ejecting device such that the guide part is disposed between the liquid reservoir and the moving body in the second direction.
