The ejection head is configured and arranged to eject liquid droplets onto a substrate. The moving body supports the ejection head, and is configured and arranged to move integrally with the ejection head with respect to the substrate. The guide part is configured and arranged to guide a relative movement of the moving body. The attachment part is attached to the guide part and supporting the moving body, and configured and arranged to move integrally with the moving body. The fixed part is fixed to the attachment part separately from the moving body. The liquid reservoir is provided to the fixed part, and configured and arranged to store the liquid supplied to the ejection head. ## Claims ### Claim 1 A droplet ejecting device comprising: an ejection head configured and arranged to eject liquid droplets onto a substrate;
