  • Patent number: 11383540
    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.

  • Patent number: 10112389
    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).
