Jack, reproducing apparatus and data communication system

A reproducing apparatus comprising:

• a jack comprising:
• an opening for selectively accommodating either a first plug or a second plug, said first plug having a plurality of first electrode terminals for performing data communication based on a first data communication standard, said second plug having a plurality of second electrode terminals for effecting data communication based on a second data communication standard;
• a plurality of first contacts for coming into contact with said plurality of first electrode terminals of said first plug when said first plug is inserted into said opening;
• and a plurality of second contacts for coming into contact with said plurality of second electrode terminals of said second plug when said second plug is inserted into said opening;
• reproducing means for reproducing information from a storage medium;
• first data converting means for converting the information from said reproducing means in accordance with said first data communication standard;
• and
• second data converting means for converting information regarding to operating status of said reproducing means in accordance with said second data communication standard.

A data communication system comprising:

• either a first plug or a second plug, said first plug including a first headphone plug and a first connector, said first connector having a plurality of electrode terminals for performing data communication based on a first data communication standard, said second plug including a second headphone plug and a second connector, said second connector having a plurality of electrode terminals for effecting data communication based on a second data communication standard;
• and
• a jack comprising:
• an opening for selectively accommodating said first or said second plug;
• a plurality of first contacts for coming into contact with said plurality of first electrode terminals of said first plug when said first plug is inserted into said opening;
• and
• a plurality of second contacts for coming into contact with said plurality of second electrode terminals of said second plug when said second plug is inserted into said opening.

A jack comprising:

• an opening for selectively accommodating either a first plug or a second plug, said first plug having a plurality of first electrode terminals for performing data communication based on a first data communication standard, said second plug having a plurality of second electrode terminals for effecting data communication based on a second data communication standard, the shape of the second plug being substantially similar to the shape of the first plug;
• a plurality of first contacts for coming into contact with said plurality of first electrode terminals of said first plug when said first plug is inserted into said opening;
• and
• a plurality of second contacts for coming into contact with said plurality of second electrode terminals of said second plug when said second plug is inserted into said opening.
