Patent ID: 7324225

Claim:
A multifunction system comprising: an image output unit that has an image signal input unit capable of receiving an optical signal, and outputs an image according to an optical signal inputted from the image signal input unit, the image output unit and the image signal input unit being disposed within a first housing; a first functional unit that has a first optical signal output unit capable of outputting an optical signal and outputs the optical signal according to a first function through the first optical signal output unit, the first functional unit and the first optical signal output unit being disposed within a second housing a second functional unit that has a second optical signal output unit capable of outputting an optical signal and an optical signal input unit capable of receiving an optical signal, and outputs an optical signal according to a second function through the second optical signal output unit, and receives an optical signal inputted through the optical signal input unit, the second functional unit, second optical signal output unit and the optical signal input unit all being disposed within a third housing; and a distribution-type optical signal transmission medium to which the image signal input unit, the first optical signal output unit, the second optical signal output unit, and the optical signal input unit are connected, and which distributes an optical signal outputted from at least the first optical signal output unit to the image signal input unit and the optical signal input unit, and transmits an optical signal outputted from the second optical signal output unit to the image signal input unit.
