Abstract
An input cord used in a headphone apparatus and an electronic apparatus is wound around a winding device such as a reel, and assembly is facilitated without using jigs when a commutator mechanism relaying to a D/U on the other side through a passage cord is installed. A terminal board including metal slip rings is provided on the side of a lower flange of a reel in left and right headphone housings, and contact points are provided on the side of a housing at a position opposed to the terminal board.

A headphone apparatus capable of winding and storing a cord around a reel pivotally fitted in a freely turnable manner to a pivot in a headphone housing, comprising:
- contact points provided in said headphone housing;
- and
- a terminal board provided in said reel and fixedly coupled to said reel so as to turn relative to the pivot as the reel turns relative to the pivot, which terminal board includes metal slip rings.
The electronic apparatus capable of winding and storing a cord around a reel pivotally fitted in a freely turnable manner to a pivot provided in an upright position in a casing of a portable electronic apparatus, comprising:
- contact points provided in said casing of the electronic apparatus, and a terminal board provided in said reel and fixedly coupled to said reel so as to turn relative to the pivot as the reel turns relative to the pivot, which terminal board includes metal slip rings.
A cord-winding device configured to wind and store a cord around a reel pivotally fitted in a freely turnable manner to a pivot in a headphone housing or casing, comprising:
- contact points provided in said headphone housing or casing, and a terminal board provided in said reel and fixedly coupled to said reel so as to turn relative to the pivot as the reel turns relative to the pivot, which terminal board includes metal slip rings.
