PROBLEM TO BE SOLVED: To certainly cool a large number of disk substrates or the like by simple constitution. SOLUTION: When the disk substrates 3 molded by an injection molding machine 1 to be taken out are horizontally accumulated around an accumulation shaft 16 to be stored, cooling air is supplied to the air introducing pipeline 19 of the accumulation shaft 16 and blown out of the venting port 20 of the accumulation shaft 16 to be sprayed on both surfaces of the disk substrates 3, which are horizontally accumulated in such a state that the upper surface of each of them is held to a constant level, to successively accumulate the disk substrates 3 while cooling them to store them. By this constitution, the disk substrates 3 can be efficiently cooled without providing a cooling stage for the disk substrates 3 taken out of the injection molding machine 1.
