Abstract
An apparatus to align a substrate and a print head having a plurality of orifices so as to perform a printing operation by ejecting ink on the substrate comprises a camera unit provided between the substrate and the print head to photograph the plurality of orifices of the print head and the substrate so as to align the print head and the substrate, and a camera moving part to movably support the camera unit and to move the camera unit between the substrate and the print head. Thus, the aligning apparatus has a simple configuration that may be easily installed and may be controlled precisely. The aligning apparatus may also be used with opaque substrates.

An apparatus to align a substrate and a print head having a plurality of orifices to perform a printing operation by ejecting ink on the substrate, comprising:
- a camera unit provided between the substrate and the print head to photograph the plurality of orifices of the print head and the substrate to align the print head and the substrate;
- and
- a camera moving unit to movably support the camera unit and to move the camera unit between the substrate and the print head.
An apparatus to align a substrate having a plurality of pixels thereon with a print head having a plurality of orifices to eject ink onto the plurality of pixels, the apparatus comprising:
- a substrate supporting member;
- a print head moving unit to movably support the print head above an upper surface of the substrate;
- and
- a camera unit movable between the upper surface of the substrate and a lower surface of the print head to receive images of the upper surface of the substrate and the lower surface of the print head to align the substrate with the print head.
