Droplet discharge head and droplet discharge device

A droplet discharge device, comprising:

• a droplet discharge head discharging a droplet to an object;
• and
• a controlling unit drive-controlling the droplet discharge head by relatively moving the droplet discharge head and the object,
• wherein the droplet discharge head includes:
• a head body having a surface opposed to the object,
• a plurality of nozzles aligned on the surface and discharging the droplet to each of positions on the object opposed to the plurality of nozzles, and
• i×j pieces of irradiation parts arranged such that I (an integer number of 1 or more) pieces of irradiation parts are aligned along an alignment direction of the nozzles and j (an integer number of 2 or more) pieces of irradiation parts are disposed in a predetermined direction that is orthogonal to the alignment direction of the nozzles and aligned along the predetermined direction;
• wherein when the controlling unit allows the object to move relatively to the droplet discharge head in the predetermined direction so as to discharge the droplet to a selected position that is selected from the positions, the controlling unit allows the j pieces of irradiation parts disposed in the predetermined direction of a nozzle opposed to the selected position to irradiate the object with light;
• wherein the irradiation parts include first irradiation parts disposed in the predetermined direction of the nozzles and irradiating a first part of a line, the line passing through each of the positions opposed to the nozzles and extending along the predetermined direction, with the light, and second irradiation parts disposed in the predetermined direction of the first irradiation parts and irradiating a second part that is different from the first part on the line with the light, and
• wherein when the controlling unit relatively moves the droplet discharge head and the object so as to discharge the droplet on a selected position selected from the positions, the controlling unit allows one of the first irradiation parts disposed in the predetermined direction of a nozzle opposed to the selected position to irradiate the first part with light and allows the second irradiation parts disposed in the predetermined direction of the nozzle opposed to the selected position to irradiate the second part with light.
