PURPOSE:To reduce a radiant noise emitted from a power line by separating a light emitting part from a circuit part to emit the light emitting part, connecting between them by a flexible cable having flexibility, and providing the ground line in the neighborhood of the power line of the flexible cable. CONSTITUTION:The light emitting part 1 is separated from the circuit part 2 to emit the light emitting part 1, and they are connected by the flexible cable 3 having the flexibility, and the ground line (l3) is provided in the neighborhood of the power line (l1) of the flexible cable 3. In such a way, it is possible to reduce the radiant noise emitted from the power line (l1) by the ground line (l3), and since only it is required to provide the ground line (l3) in the neighborhood of the power line (l1), the structure of a device can be simplified, and the flexibility of the flexible cable 3 can be prevented from being impaired. |
