PROBLEM TO BE SOLVED: To provide an indicator system where power consumption can be reduced by making the reduction of light quantity little and without increasing the number of parts even if the same status is simultaneously displayed in two parts or above and to provide a compound lens used for the system. SOLUTION: In technology for simultaneously displaying the same status in the plural parts, the status is displayed in plural directions by using the first light emitting direction and the second light emitting direction of one light source. Thus, the compound lens provided with a first light emitting face, the second light emitting face, a first concave-shaped curve face 25 reducing the surface reflection of the light of the light source and guiding it to a first light emitting face and a second concave-shaped curve 26 reducing the surface reflection of light from the light source and guiding light to the second light emitting face is used. Consequently, the status can be displayed in the plural directions with one light source. Even if the same status is simultaneously displayed in the two parts or above parts, the number of parts are not increased or power consumption can be reduced. |
