[0004]

For example, in a basketball game, for example, the display of the score of the team, the remaining time of the game, and the like are usually displayed by a display, and this display is installed at a place where the spectators can best see. On the other hand, since the display operation panel of the display is placed in the referee's seat and operated by the referee, the two are often set far apart, and in this case, a cord having a length of several tens of meters is used. Connected. A code for transmitting such a signal is usually composed of a single cord, and connectors are connected to both ends. l
In the book cord, when wound on a reel from the end,
Since one end of the connector is hidden under the wound cord, it is necessary to release the entire cord when used. In such a case, since the code is generally set to be longer, it is necessary to solve it for an unnecessary length, which is troublesome, and there is a problem that the solved code is scattered on the floor.

[0005] In the above-described structure in which the cord is divided into the primary side cord and the secondary side cord, the ends of which are fixed to the support shaft and the reel, respectively, and the winding device integrated type structure, a commercially available cord cannot be used. There's a problem. Also, in a structure in which the primary and secondary cords are divided and connected by sliding contacts, problems such as contact failure due to wear of the contacts are likely to occur. In particular, when the code is a signal line, the number of cores of the connector is as large as 2 to 25 cores, and accordingly the sliding proportional point is also increased. Since the current is as small as several tens of mA, the contact failure due to wear of the contacts. Is a major problem. Therefore, it is desirable that the winding device has a structure capable of winding one cord. In addition, it is desirable that the length of the cord can be adjusted so that the length on one terminal side and the length on the other terminal side can be adjusted according to the installation location of the display.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a cord winding device capable of winding a single long cord.

Another object of the present invention is to provide a cord winding device in which the lengths of both terminals can be adjusted.
