  • Patent number: 6338561
    Abstract: The invention provides a luminous pointer which can offer an increased commercial value with its glowing surface having the ability to glow generally uniformly. The luminous pointer is constructed of a pointer element 1 which is made of a light-transmitting material and forms an indicating portion (glowing surface) 2, a light-blocking cover 10 which covers a central region of swing motion R of the pointer element 1 and opens rearward, and a shielding element 12 which covers the rear side of the central region of swing motion R of the pointer element 1. The pointer element 1 has in its central region of swing motion R reflecting parts 4 to 7 for reflecting illuminating light fed from the rear side at least toward its tip end, and the shielding element 12 has exposing parts 123 for exposing the reflecting parts 4 to 7 of the pointer element 1 and is formed of a light-transmitting material which makes it possible to adjust the amount of transmission of the illuminating light.
