Abstract: A printing unit includes a plurality of ink jet parts and an X-axis linear motion mechanism that moves each of the plurality of ink jet parts in the same main scanning direction. The X-axis linear motion mechanism moves the ink jet part involved in printing the workpiece among the plurality of ink jet parts so as to face the surface of the workpiece and moves the remaining ink jet part on the one X-axis linear motion mechanism so as to retreat from the surface of the workpiece. As a result, a printing apparatus that is capable of printing accurately onto the workpiece having a three-dimensional curved surface is provided.

IPC: B05C5/02
Abstract: An displacement-expansion mechanism and a liquid-coating apparatus including the same can achieve high-speed and stable control of coating of high-viscosity liquid materials. The liquid-coating apparatus, includes: (a) a nozzle hole from which a liquid material is discharged; (b) a supply flow channel that supplies the liquid material to the nozzle hole; (c) a plunger that reciprocates in contact with the liquid material inside the supply flow channel; (d) a displacement-expansion mechanism that displaces the plunger; and (e) an actuator that displaces the displacement-expansion mechanism, wherein at least either of contact parts of the displacement-expansion mechanism and the actuator has a curved surface.

Abstract: A liquid discharge device is used that includes: a nozzle having a first holding part and a second holding part and for discharging a liquid droplet; a base to which the nozzle is attached; a fixing part for fixing the nozzle to the base; and a drive part that creates displacement in the nozzle. The drive part holds at least one of the first holding part and the second holding part. Whichever of the first holding part and the second holding part that is not held by the drive part is held by the fixing part.

Abstract: In a common chamber (102) for distributing, to respective pressure chambers (211), an ink supplied from the ink inlet (101), resistant walls (111) are provided in areas that are located ahead and behind of the flow of the ink, i.e., areas around inlets of flow channels (221) that lead to respective pressure chambers (211), and any resistance against the flow of the ink is generated according to the heights of the resistant walls (111), thereby capturing a solid ingredient (150) included in the ink. In this case, by adjusting the heights of the resistant walls (111) to control capabilities of introducing the solid ingredient (150), it becomes possible to dispense desired amounts of the solid ingredient (150) to the respective pressure chamber (211).
