PROBLEM TO BE SOLVED: To simplify the structure, improve durability, reduce manufacturing cost as well as improve product quality by reducing light guides composed of radial pieces which are conventional mechanical composition parts, to have light weight and small sized by small depth dimension due to having a pointer and guide lights not necessary, to improve visibility by having an arc-state trajectory of LED as a residual image instead of the pointer and to improve freedom in design by reducing the guide lights.SOLUTION: The structure has a discoid substrate 1 with LED2 implemented in proximity of an outer periphery attached to a motor shaft 5, a trajectory of light emission replacing a pointer by having the timing of LED light emission by revolving the motor 3 at a constant speed controlled by a control device and displayed as an arc by a residual effect. |
