A signal communication apparatus includes a transmission component, a reception component and an identification information storage component. The transmission component is connectable to an information processing device and a signal propagation medium, and transmits an inputted image signal through the connected signal propagation medium. The reception component is connectable with an image display device and the signal propagation medium, receives the image signal transmitted from the transmission component through the connected signal propagation medium, and outputs the image signal to the connected image display device. The identification information storage component is removably attached to the transmission component, and stores identification information for identifying the image display device. The information processing device acquires the identification information from the identification information storage component connected to the connected transmission component, and outputs the image signal to the connected transmission component in accordance with at least a portion of the acquired identification information.

Optoelectric composite wiring module and information processing apparatus

The first and second light-emitting regions are provided on the light source. When the first optical fiber having the first core diameter is connected, the light emitted from the first light-emitting region enters the first core. When the second optical fiber having a greater core diameter than the first core diameter is connected, the lights emitted from the first and second light-emitting regions enter the second core. It is thus possible to connect the optical transmission device with multiple optical fibers having different core diameters. It is thus possible to provide the optical transmission device and the communication device, which are low in cost and high in convenience.

A multifunction system has advanced functions and high speed capability and is excellent in expandability. The multifunction system includes a controller, an IIT, an IOT, and a light distributing device. For a print job, print data outputted from the controller is converted into optical signals, which enter a light distributing device and are transmitted to the IOT of the emission side. The IOT prints the received data onto a printer. For a copy job, copy data outputted from IIT is converted into optical signals, which enter the light distributing device, and are transmitted to the IOT of the emission side. For a scan job, scan data outputted from the scanner is converted into optical signals, which enter the light distributing device, and are transmitted to the controller of the emission side. The controller processes the received data.

Multifunction system

In an optical transmission apparatus in which a plurality of nodes are optically connected to one another via an optical transmission path, a light signal which is coded so that a mixture ratio of 1 and 0 constituting data is made close to 50% is transmitted through the optical transmission path. When a light signal is not emitted from all of the nodes, a dummy signal which is an AC-like signal is emitted to the optical transmission path. Therefore, an optoelectric conversion section can be always set to an active state, and the signal recognizability can be prevented from being lowered.

In a device of the present invention for allowing signal light to enter a light guide body using an optical fiber, a light guide body, which is constituted by dispersing particles for scattering the signal light in an optical medium, is selected as a light guide path which requires an area where a light diffusing function is performed just after incidence of the signal light. An optical connecting material intervenes between one end of the optical fiber from which the signal light is output and opposed one end surface of a particle dispersing light guide body and a desired diffusing function is obtained.

Light signal transmitting device and signal processing device

A light-emitting device includes 16 vertical-cavity surface-emitting laser diodes (VCSELs) disposed like a 4&#xd7;4 grid, for example, in a sufficiently narrower range than the end surface of an optical fiber. The 16 VCSELs disposed in the light-emitting device emit optical signals in the same direction. Since the VCSELs are disposed with a concentration in the sufficiently narrower range than the end surface of the optical fiber as described above, if the optical signals emitted from the VCSELs are spread, almost all optical signals generated by the light-emitting device are incident on the end surface of the optical fiber and are transmitted through the optical fiber.
