[Conventional technology]

In the conventional spherical surface processing apparatus, as shown in FIGS. 8 to 11, a polishing dish 50 or a polishing holder 51 is rotated and swung to remove a workpiece (hereinafter simply referred to as a lens material) 52 such as an optical lens or a mirror. It is known that the polishing dish 50 is pressed on a spherical core axis to form a spherical surface. In such a spherical surface processing device, in order to convey optical lenses, mirrors, etc., the lens material 52 is conveyed to a predetermined position by a container 54 on a transfer machine 53 composed of a transfer belt conveyor installed on the side of the polishing dish 50. Then, the fixture 55 attached to this transfer machine 53
The container 54 is fixed on the transfer device 53 by. By the suction pad 57 of the transfer robot 56 which is separately provided from that state,
The lens material 52 is adsorbed and transferred onto the polishing dish 50, and the lens material 52 on the polishing dish 50 is held and fixed by the polishing holder 51 and polished. After polishing the lens material 52, the lens material 52 is returned to the polishing dish 50 again, the lens material 52 is adsorbed by the adsorption pad 57 of the transfer robot 56, and the lens material 52 is stored in the empty container 54. Transfer machine 53
