PURPOSE:To shorten the lifting distance of a carrier and to decrease the overall height of the lifting device by so constituting a conveyor that a carrier body can be lifted diagonally with respect to a process tank. CONSTITUTION:When a carrier 11 approaches to a flux tank 5, the butt plate 45 of a carrier body 34 is placed on the 3rd receiving plate 72 and is then placed on the 2nd receiving plate 71. The 1st roller 38 is therefore prevented from descending into the 2nd recess 68 and when the plate 45 passes over the 2nd receiving plate 71, the 1st roller 38 contacts with the right slope of the 1st recess 67 and begins to descend. When the carrier 11 is further conveyed toward an arrow H, the 1st roller 38 and the 2nd roller 43 put downward the carrier body 34 and advance into the flux tank 5 while rolling on the respective slopes of the recesses 67 and 69 toward an arrow J. The carrier body 34 regains the horizontal position upon arriving of the rollers 38, 43 at the base of the recesses 67, 68 then the motor is once stopped and a flux is blown to a printed board 82. |
