A rotating frame 22 is supported by a stationary frame 21 rotatably by 180 degrees, and in both side plates 22c of the rotating frame 22, there are formed four pairs of guide grooves 25-28 for guiding pallets 9 and slots 32a-32d for moving claw members 30, 31, said slots corresponding to said guide grooves 25-28. On an inner wall of a rear plate 22b of the rotating frame 22, there is provided an up and down movable member 47 which moves downward together with the claw members 30, 31 when the rotating frame 22 is rotated by 180 degrees. Into the first and third guide grooves 25 and 27, there have been previously inserted empty pallets 9 with such a posture that their front surfaces 11 face downward. By moving the claw members 30, 31 along the slots 32b, 32d, the pallets 9 having discs D placed thereon are drawn into the second and fourth guide grooves 26 and 28 such that these pallets 9 are opposed to the upper empty pallets 9. In this condition, when the rotating frame 22 is rotated by 180 degrees, the discs D are turned-over and are placed on the lower empty pallets 9.
