ABSTRACT:
A structure in which a toy is driven by a magnetic force including a rotary disk having a plurality of inner magnets thereon, with one magnet located at the center of the disk and the other magnets spaced therefrom. The polarity of the magnet in the center of the disk is different from the polarity of the remaining magnets. A mirror is mounted over the outer magnets and a plurality of inner magnets, each bearing a toy, are supported on the mirror. The polarity of the outer magnets is opposite the polarity of the inner magnets and is the same as the polarity of the inner magnet at the center of the rotary disk. The rotary disk may be driven to rotate by an outer driven wheel which, in turn, is rotated by a driven claw. The rotary disk is supported above a fixing disk. The driven wheel engages and rotates the rotary disk, causing movement of the outer magnets and toys on the mirror along the path of rotation of the inner magnets due to the magnetic attraction between the magnets of opposite polarities. The outer magnets are repelled from movement toward the center inner magnets because of their similar polarities with the inner magnet at the center of the rotary disk. The fixing disk engages an annular groove in a cylindrical substrate that tightly secures the mirror without the use of adhesives.
