Inkjet printer and printing method

摘要

It aims to provide an inkjet printer and a printing method that appropriately performs printing with high accuracy on print objects having various shapes. As a solution therefor, an inkjet printer is configured to perform printing using an inkjet scheme on a print object and includes an inkjet head that discharges ink droplets, a guide rail that retains the inkjet head by making the inkjet head face the print object and that is a Y direction extending member extending in a predeterminedly set Y direction, and an X direction driving section that moves the guide rail in an X direction and upon printing, the inkjet head moves along the guide rail and discharges ink droplets toward the print object, and the X direction driving section includes a ball screw and moves the guide rail in the X direction in accordance with a rotation amount of the ball screw.

主权项

1. An inkjet printer configured to perform printing using an inkjet scheme on a print object, the inkjet printer comprising:
an inkjet head that discharges ink droplets; a Y direction extending member that retains the inkjet head by making the inkjet head face the print object and that extends in a Y direction predeterminedly set in the inkjet printer; and an X direction driving section that moves the Y direction extending member in an X direction orthogonal to the Y direction, wherein upon printing, the inkjet head moves along the Y direction extending member and discharges the ink droplets toward the print object, and the X direction driving section includes one ball screw and moves the Y direction extending member in the X direction in accordance with a rotation amount of the ball screw, the inkjet printer further comprising:
a guiding member that guides movement of the Y direction extending member in the X direction by a structure that extends in the X direction; anda guided section that is disposed at sides of the Y direction extending member, and the Y direction extending member is movable along the guiding member, and the Y direction extending member is movable in the X direction,the ball screw is disposed at a central position in the Y direction of the Y direction extending member.
