Abstract

A signal line from a common terminal, which allows the insertion of a terminal of a cable for transmitting high-frequency signals or the insertion of a terminal of a cable dedicated to the transmission of audio signals, is branched into one line which is connected to one end of a high-frequency signal switch (USB switch) and the other line which is connected to one end of an audio signal switch (audio switch), respectively. A signal line from the other end of the high-frequency signal switch is connected to a target circuit. A signal line from the other end of the audio signal switch in a primary hierarchical position is branched into a plurality of lines, and the respective plurality of lines are connected to one end of audio signal switches (e.g., headphone switch and microphone switch) in a secondary hierarchical position. And the respective signal lines from the other end of the plurality of audio signal switches of secondary hierarchical position are connected to respective target circuits.
