<p>PROBLEM TO BE SOLVED: To transmit high-quality signals by eliminating stab wiring to a high- speed and low-amplitude signal such as a differential signal while using a substrate mounting a driver for outputting and transmitting the signals of different electric characteristics such as the signal of single end and the differential signal from one output pin. SOLUTION: Concerning an information processor provided with an input means, control means 2 for stitching the plural kinds of electric signals having different electric characteristics corresponding to modes, transmission line 5 and branched transmission line 6 for respectively receiving the electric signals, and output means, in this case, the branched transmission line 6 has a disconnection/connection setting part 61. As the disconnection/connection setting part 61, a connecting element 71 is mounted or not mounted between terminals, a switching semiconductor element 72 is used and disconnected or connected according to an instruction from the control means 2, and the transmission line 6 is disconnected or not disconnected.</p> |
