Abstract

A liquid droplet ejection device for ejecting a liquid from a nozzle of a head to a workpiece, the liquid droplet ejection device including: a table for loading the workpiece; a first shifting section capable of shifting the table in a first direction and in a second direction approximately intersecting the first direction at a right angle; a plurality of carriages having the head; and a second shifting section capable of positioning each of the carriages by mutually shifting each of the carriages along the second direction.

Claims (8)

1. A liquid droplet ejection device for ejecting a liquid from a nozzle in a head to a workpiece, the liquid droplet ejection device comprising:

a table for loading the workpiece;

a first shifting section for shifting the table in a first direction and a second direction intersecting the first direction at approximately a right angle;

a plurality of carriages, each of the plurality of carriages having a head; and

a second shifting section for positioning each of the plurality of carriages independently in the second direction and selecting at least one of the plurality of carriages so that the workpiece faces the at least one of the plurality of carriages and so that the workpiece does not face a remainder of the plurality of carriages.

2. The liquid droplet ejection device according to claim 1 , comprising a maintenance section arranged at least at one position of the second direction for recovering an ejection capacity of the nozzle, the second shifting section positioning the remainder to face the maintenance section.

3. The liquid droplet ejection device according to claim 1 , the second shifting section selecting the at least one of the plurality of carriages depending on a width of the workpiece.

4. The liquid droplet ejection device according to claim 1 , the second shifting section controlling a total arrangement width of the heads of the plurality of carriages so as to correspond to a width of the workpiece by varying the number of carriages.
