PROBLEM TO BE SOLVED: To confirm the power source state even when an existent power lamp is hidden behind an optical filter or the like by providing a pilot lap which can display the electrification state or the like of a display device at an arbitrary position. SOLUTION: A display unit 20 comprises a pilot lamp 21, an optical fiber 22 and a light incidence part 23. The light incidence part 23 is provided at one end part of the optical fiber 22, an optical fiber end surface and a power pilot lamp 9 on a housing of a display monitor 1 are brought into contact, and a fitting member 24 shields the periphery of the contact part from light. The pilot lamp 21 is arranged an other end part of the optical fiber 22 and a lens 25 is installed on the end surface of the optical fiber 22 by adhesion or the like. Consequently, the display light of the power pilot lamp 9 is emitted to the lens 25 of the pilot lamp 21 constituting the display unit 20 as it is, so the display unit 20 can display the power source state without having its own power source. |
