PURPOSE: To naturally pull off a cup by adsorbing the inner face of the cup with a plurality of adsorbing members and forming a gap toward other cups to pull off the cup at the time of taking out superposed cups formed with paper or sheet, etc., one at a time.

CONSTITUTION: A number of cups 2 are mutually superposed and placed in position. A frame body 8 is lowered and adsorbing members 1 enter the inside of a cup 2. The entered adsorbing members 1 are moved by the action of an air cylinder 3 and adsorbes the inside face of the cup 2 and, then the adsorbing member 1 is again returned to its original position. As the adsorbing members 1 are returned to the original position, the inside of the cup 2 is deformed forming a gap toward a cup on the lower portion. When the frame body 8 and adsorbing members 1 are lifted up in this condition, the cup 2 is equally lifted up and pulled off and, in a stage where it is lifted up to a certain height, a slider 9 is moved along a rail 12 to cut off air which is connected to the adsorbing members 1 in a defined position, thereby, removing the adsorption to release the cup 2.
