Abstract

A droplet discharge head (1) includes a lower housing (10b), an upper housing (10a), a nozzle plate (101), a shaft-shaped member (113), and a driver (114). The lower housing (10b) includes a flow channel (112). The upper housing is on the lower housing and detachable from the lower housing. The nozzle plate is on a lower surface of the lower housing. The shaft-shaped member includes a valve element (113a) at a tip end of the shaft-shaped member to open and close a nozzle orifice (111) of the head. The shaft-shaped member is reciprocatable in the upper housing. The driver is in the upper housing and reciprocates the shaft-shaped member in an axial direction of the shaft-shaped member. The shaft-shaped member is movable in the axial direction such that a length of the tip end of the shaft-shaped member protruding from the lower surface of the upper housing is shortened.
