  • Patent number: 10108019
    Abstract: A projection kaleidoscope has a shell, a light supply device, a rotating device, a film unit, a reflex cone, and a projecting convex lens. The light supply device is mounted in the shell and has a light-emitting part and a light converging unit. The rotating device is mounted in the shell and has a driver and a transmission connected to the driver. The film unit is mounted on the transmission of the rotating device and faces the light converging unit of the light supply device. The reflex cone is mounted on the transmission of the rotating device and faces the film unit and the projecting opening. The projecting convex lens is mounted in the shell and faces the reflex cone. The rotating device drives the film unit and the reflex cone to rotate in reverse to each other.
