The upper station 2 and the lower station 3 have horizontal placing tables 5 and 6, respectively. The horizontal placing tables 5 and 6 move only in the horizontal direction. The lifting and lowering placing tables 10 and 11 move only in the vertical direction. When any of the lifting and lowering placing tables 10 and 11 is in the upper station 2, the upper side horizontal placing table 5 is at a position adjacent to the lifting and lowering placing tables 10 and 11 to form a series of conveying passages. When the lifting and lowering placing tables 10 and 11 move away from the upper station 2, the upper side horizontal placing table 5 moves to a position where the lifting and lowering placing tables 10 and 11 used to exist. When the lifting and lowering placing tables 10 and 11 move away from the lower station 3, the lower side horizontal placing table 6 moves to a position where the lifting and lowering placing tables 10 and 11 used to exist. ## Claims ### Claim 1 A lifting device comprising: an upper station;
