PROBLEM TO BE SOLVED: To provide a karaoke apparatus made easy for connection between a plurality of apparatuses. SOLUTION: In this karaoke apparatus made up by housing five equipment, a monitor 5, a karaoke apparatus body 1, a voice adaptor 2, an amplifier 3, and a DVD changer 4 in a rack 10, optical fibers 12 (12a to 12e) is laid on a back plate 11 of the rack 10, and infrared input/output terminals 13 (13-1a to 13-5d) are provided in positions confronting the optical fiber, of back surfaces of the plurality of apparatus. Because the optical fiber 12 is made of a soft resin, it can be deformed by being pressed from the lateral side to cause transmitted light to leak out therefrom. Each infrared input/output terminal 23 is constituted of a tip part of optical fiber made of a hard optical resin, deforms the optical fiber 12 by being pressure-attached thereto, and can input or output laser beam signals into or out of the optical fiber 12. Connection for transmission lines is completed by merely installing the equipment 1 to 5 in the rack 10. |
