PURPOSE:To improve the working efficiency, by forming a disk holding mechanism in such a way that the mechanism can simultaneously hold plural pieces of disks with their centers being put in order. CONSTITUTION:Firstly, three pieces of disks 1 are placed on a disk placing table with their centers being put in order and a distance (d) between each of them. Secondly, a hollow shaft 5, from which a shaft 6 is removed, is inserted into the circular holes 11 of the three disks 1 and the front end section of the outside member 71 of a holding tool 7 is fitted to the edge of the circular hole 11. When the shaft 6 is inserted into the hollow section 52 of the hollow shaft 5 under this condition, the outside member 71 of the holding tool 7 is projected from the hollow shaft 5 and holds the disk 1 from the inside of the circular hole 11.
