Abstract: Disclosed is an ascent and descent apparatus for a liquid material spray printer, which may control a distance between a subject and a spray assembly optimally. The apparatus includes a sliding member having a pair of sliders selectively reciprocating oppositely by a driving unit; a frame installed above the sliders and having an elongated guide hole corresponding to a reciprocating range of the sliders; and a pair of crosslink members installed to an upper surface of the frame to couple with the sliders through the hole and whose upper end supports a flat table. The crosslink members include a pair of unit links hinged at their substantial center, whose lower ends are respectively coupled to the slider and hinged to the frame, and upper ends are respectively hinged to the flat table and supports the flat table rotatably, whereby the flat table is lifted by reciprocation of the sliders.

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.

Abstract: Disclosed is an ascent and descent apparatus for a liquid material spray printer, which may control a distance between a subject to be coated and a spray assembly optimally. The apparatus includes a predetermined number of rotary shafts installed in a vertical direction and having spiral ridges on outer circumferences thereof, the rotary shafts being selectively rotated by a driving motor; and a lifting member installed to the rotary shafts to support a transferring table to which a subject to be coated is mounted, the lifting member having a spiral ridge with a shape conforming to the spiral ridges of the rotary shafts so that the transferring table is lifted when the rotary shafts are rotated.
