PURPOSE: To obtain high quality interior and exterior panels of building that are stably etched and automatically etching treat an object to be treated through respective processes, thereby reduce production cost. CONSTITUTION: The apparatus is characterized in that a plurality of transfer rollers(1,1') simultaneously rotated by driving motor are laterally and continuously arranged in such a way that etching tank(10), first cleaning tank(20), first removal tank(30), second cleaning tank(40), second removal tank(50) and third cleaning tank(60) are continuously formed from one side of the transfer rollers, wherein a cover(3) into which downward injection nozzles(2,2') are inserted is formed at the upper side of the transfer rolls in the etching tank, first cleaning tank, first removal tank, second cleaning tank, second removal tank and third cleaning tank, a filtering mesh(5) and a catchment can(6) are installed at the center of an inclined collection plate(4) at the lower side of the transfer rollers so that the catchment can is formed on the bottom of the filtering mesh, the catchment can and the injection nozzles are connected by a supply pipe(8) of circulation pump(7) mounted on one side of the catchment can, a separate discharge pipe is formed on an upper part of cover of the etching tank so that the discharge pipe is communicated with the inside of the cover, and opening and closing holes are respectively formed at the center of the cover of the first cleaning tank, first removal tank, second cleaning tank, second removal tank and third cleaning tank in such a way that separate opening and closing covers are detachably mounted on the opening and closing holes.
