| 1. A structure in which a receptacle that can detect the insertion and extraction of a plug is mounted on a circuit board,
the structure comprising:
a receptacle shell having formed therein a plug insertion port into which said plug is inserted and from which said plug is
extracted;
a receptacle body provided inside said receptacle shell;
a movable contact that is installed at a base portion of said receptacle body, said base portion faces a distal end of said
plug when said plug is inserted into said plug insertion port, and that is deformed elastically when pushed by said plug inserted;
and
an immovable contact that is installed at said base portion, is normally spaced from said movable contact, and comes into
contact with said movable contact when said movable contact is pushed by said plug and elastically deformed;
wherein an electric circuit for detecting that said movable contact and said immovable contact are in contact with each or
separated from each other is provided at said circuit board; and
said electric circuit has an electric power line connected to one of said movable contact and said immovable contact, a ground
line connected to the other of said movable contact and said immovable contact, and a detection line that is connected to
said movable contact or said immovable contact and serves to detect a voltage.
