DROPLET DISCHARGE APPARATUS, DROPLET DISCHARGE HEAD, AND DROPLET SUPPLY METHOD

摘要

There are provided a droplet discharge apparatus and a droplet discharge head capable of discharging stable state droplets onto a plurality of areas with a predetermined pitch while maintaining a unified height between a plurality of heads. A method for supplying droplets is also provided. The droplet discharge apparatus comprises at least one head (20) for discharging a droplet onto a predetermined position from a nozzle (23) by driving of an electrical drive element and a support member (10) for supporting the head (20). The head (20) has a pair of side surfaces (26) with a base on which the nozzle (23) is formed, and each of the side surfaces (26) includes a recess and an abutting surface (30) against other head (20). The pair of abutting surfaces (30) of the head (20) are parallel with each other. The support member (10) is located inside the recess and has a support part for supporting the head (20) from the side of the nozzle (23) located in the discharging direction. Arranging the plurality of heads (20) so as to abut on each other at the abutting surface (30) makes it possible to form a head group (G) in which the nozzles (23) are arranged with predetermined pitch and height (H).
