Next, the reel mounted on the case body 11 is rotated to adjust the urging force of the mainspring 5 and to adjust the winding method of the drawn round cord 3 and the flat cord 4 to obtain the flat cord 4. Into the flat cord fixing portion 16 of the case body 11 as shown in FIG. After this, the center shaft 13 of the case body 11 is
Attach the case cover 12 so as to fit the case 7, and screw the four parts of the case body 11 and the case cover 12 with screws. Thus, the cord winding device is configured.

FIG. 1 shows a state in which the draw-out round cord 3 is stored by the restoring force of the mainspring 5. The state of FIG. 2 shows a state in which the drawn round cord 3 is completely stored in the case by the restoring force of the mainspring 5.
FIG. 3 shows a state in which the flat cord 4, which is a non-pull-out cord at that time, is wound clockwise. When the pull-out round cord 3 is pulled out from the state shown in FIG. 3, the draw-out round cord 3 is rotated to the counterclockwise direction in FIG. 3 and the clockwise direction in FIG. . Then, in FIG. 6, the spring partition plate 6 is held in a state where the inner diameter end of the mainspring 5 is fixed by the spring locking portion 14.
Since the upper spring engaging portion 69 rotates clockwise, the mainspring spring 5 is in a wound state. In addition, spring partition plate 6
When 1 rotates, the mating claw 73 of the spring partition plate 61 and the mating claw 72 of the cord partitioning plate 63 in FIG. 4 are fitted together, so that the cord partitioning plate starts rotating counterclockwise in FIG. Then, the flat cord 4 which is a non-pull-out cord has its inner peripheral end regulated by the through cutout 70 and the hollow shaft 62 of the cord separating plate 63 and its outer peripheral end fixed to the flat cord fixing portion 16. , The flat cord 4 expands into the case. When the drawer cord 3 is pulled out to the limit, the flat cord 4 is in the maximum spread state as shown in FIG.

Next, when the force for pulling the pull-out round cord 3 is removed from the state shown in FIG. 5, the force that forced the spring 5 shown in FIG. 6 into the expanded state disappears, and the spring 5 returns to its natural state. FIG.
Rotate counterclockwise at. Then, in FIG. 2, the spring partition plate 61 rotates clockwise, and the drawn-out round cord 3 starts to be wound around the winding portion 64 of the reel. At this time, the pull-out round cord 3 is connected to the winding guide 7 shown in FIG.
5 and the winding guide 65 shown in FIG. Then, the modular plug attached to the other end of the drawer round cord 3 is wound up until it hits the drawer opening 15 of the case. In FIG. 5, the cord partitioning plate 63 rotates clockwise,
Then, since the inner peripheral end of the flat cord 4 regulated by the hollow shaft 62 and the through notch 70 is rotated clockwise, the flat cord 4 having the fixed outer peripheral end is wound up and the number of windings is increased, so that the inside of the case is increased. The flat cord 4 having a constant length has a smaller winding diameter, and finally becomes as shown in FIG.

In the embodiment, as shown in each figure, a modular plug is installed at the tip of the round cord 3 and the flat cord 4 in order to correspond to a handset cord which handles a signal in particular. Since the present invention can be applied to a code other than a code for handling a signal, another connector may be used.

In this embodiment, a four-core cord is used for the drawer cord 3, which is designed to easily maintain a round shape even if the cord cover is thin. Although the flat cord 4 is a parallel cord having four cores, the expansion of the flat cord can be optimized by increasing the number of core wires without relying only on the cord cover of the flat cord. The scope of the present invention is not limited to the number of core wires.

The flat cord is required for the case by using a flat cord having a thickness of 1.9 mm for the non-drawing cord, compared with a case where a round cord having the same diameter of 3.4 mm as the drawing cord is used for the non-drawing cord. Was reduced. As an example, if the cord is a handset cord for a telephone or the like, it is sufficient that the drawer of the drawer circle cord has a length of 90 cm, and at this time, the flat cord in the case only needs to be about 76 cm. However, the longer the drawer length of the drawer circle cord, the longer the non-drawer cord and the greater the effect of the present invention.

[0018]

By using a flat cord as the non-pull-out cord, the diameter of the case requiring the non-pull-out cord can be reduced, so that the cord winding device can be made compact. Further, by using a four-core cord as the drawer cord, a round, thick and hard cord cover is not required.
Further, it is possible to increase the number of core wires of the flat cord and to adjust the winding and unfolding.
