Abstract
A droplet discharge device for discharging a droplet into recess parts of a storage vessel includes a storage vessel, a discharge head configured to insert a discharge surface into a recess part and discharge droplets while moving in two horizontal directions, a mounting table, a vertical position adjusting part configured to change a relative vertical position between the head and table, a vertical position adjustment control part configured to control the adjusting part, a horizontal position detecting part configured to detect a horizontal position of the storage vessel, and a target position detecting part configured to detect, before starting discharge, a distance from a vertical reference height to a discharge target surface, wherein the control part controls, based on the detected distance, the vertical position of the head or table during the discharge such that a discharge height of the discharge surface relative to the discharge target surface stays constant.
