Abstract: A valve type nozzle controls discharge of liquid by opening and closing an discharge port by a valve element, the discharge port being configured to discharge the liquid, and the valve element being formed movably by applying a predetermined voltage to a piezoelectric element, whereby when the predetermined voltage is applied to the piezoelectric element, the valve element moves in a direction where the moving mechanism opens the discharge port when the piezoelectric element extends. This allows the liquid to be discharged. Further, when the application of the voltage to the piezoelectric element is released, the moving mechanism returns to an original shape, by which the valve element closes the discharge port is closed to prevent the discharge of the liquid.

Abstract: A liquid jet device includes a head that discharges liquid to an object; a moving mechanism that moves at least one of the object and the head; and a controller that causes the head to discharge the liquid while moving the at least one of the object and the head in a first direction to form a first row of dots, and causes the head to discharge the liquid while moving the at least one of the object and the head in a second direction opposite the first direction to form a second row of dots that overlaps the first row of dots. The controller causes the center of the first dot in the second row of dots to be shifted from the center of the last dot in the first row of dots by a distance greater than or equal to a distance d.
