THREE-DIMENSIONAL INKJET PRINTER

摘要

An object is to enhance a quality of a printed image by making a positional relation between an inkjet head and a printing position of a medium uniform. A head carriage (21) is mounted on a base (10) of a 3D inkjet printer (1). The head carriage (21) carries an inkjet head (20) that is moved along a Y-axial direction by a Y-axial driving unit (22). Furthermore, on the base (10) stands a Z-axial supporting unit (32) atop an X table (31) that is moved along an X-axial direction by an X-axial driving unit. A medium holding unit (40) that is moved up and down along a Z-axial direction by a Z-axial driving motor (37) is mounted on the Z-axial supporting unit (32). The medium holding unit (40) includes arms (42a) and (42b) that jut out in the X-axial direction from a Z table (41) mounted on a Z-axial driving unit (23), an A-axial rotating unit (43) that is swung in an A-axial direction by an A-axial driving motor (45), and a chuck (44) that is rotated in a B-axial direction by a B-axial driving motor (46) and that holds a medium (M) .
