Abstract: Disclosed is a transferring apparatus for a liquid material spray printer, which prevents shaking of a transferring table generated when the transferring table on which a subject to be coated is mounted is reciprocating. The transferring apparatus includes a flat table; a pinion gear installed to the flat table to transfer a driving force; a support roller installed to the flat table and having magnetism; and a transferring table installed to an upper portion of the flat table and supported by the support roller. A rack gear to be engaged with the pinion gear is installed to a lower surface of the transferring table to reciprocate within a range so that liquid material sprayed from a spray assembly is coated on a surface of the subject. Thus, shaking of the transferring table is prevented due to the magnetism of the support roller while the transferring table is reciprocating.
