2. Description of the Related Art In recent years, with the demand for smaller and lighter devices and improved portability, the processing of earphones and earphone cords becomes a problem when the devices are carried and used. When carrying the device in a pocket of clothes or the like, usually the earphone is rolled up and put in the pocket at the same time, or as shown in FIG. 9, the device main body 1 is wrapped with the cord 3 having the earphone 2 wound around. ing.

However, if the cord is used in such a state, there is a risk that the cord may be knotted, or the corners of the main body may hit or rub against other objects, causing the cord to break.

In order to solve these problems, an earphone housing device has been proposed in which an earphone cord is housed in the main body.

[0005]

By the way, if the cord is to be housed in the cord body, a mechanism for winding the cord must be formed in the body, which complicates the body structure and increases the manufacturing cost. . In addition, the main body had to be increased by the amount of this winding mechanism, and it was not necessarily said that it had good portability.

[0006] Therefore, the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an earphone storage device which suppresses damage to the cord without increasing the size of the main body and is excellent in portability. To do.

It is characterized in that a code guide having a predetermined length of the book is provided.

[0009]

According to the first aspect of the present invention, as shown in FIG. 1, the U-shaped groove 11 is formed over the entire circumference of the body side surfaces 21a to 21d.
Since the cord is formed and the cord is wound around the groove, it is possible to prevent the cord from hitting or rubbing against other objects.

According to the second aspect of the present invention, since the cord guide 17 is provided in the groove 11 (FIGS. 7 and 8) in addition to the above-mentioned action, the cord 3 can be wound at a predetermined position. This makes it possible to facilitate the winding work.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 are views for explaining a first embodiment of an earphone storage device according to the present invention applied to a radio.

First, in the earphone housing device 10 applied to the main body 21 of the radio, as shown in FIG. 1 in the earphone housing state, U-shaped grooves 11 are continuously formed on the side surfaces 21a to 21d of the main body 21 over the entire circumference. It is provided. This U-shaped groove 1
A cord 3 is wound around 1. The depth of the U-shaped groove 11 is such that the cord 3 does not project from the surface of the main body, that is, the side surfaces 21a to 21d when the cord 3 is wound around the groove.

Also, U is provided on the side surface 21a which is the upper surface of the radio.
Opposed projecting side portion 1 forming groove 13 wider than V-shaped groove 11
2a and 12b are provided. The opposed protruding side portions 12a, 12
As shown in the figure, the earphone 2 is housed in the groove 13 formed by b. As shown by an arrow P in FIG.
Is abutted against the side surface 21a and slid to be stored. In the case of this example, the cord 3 is pulled out from the cord pull-out hole 15 provided in the configured groove 13. 24
Is a hemispherical protrusion provided inside the opposing protrusions 12a and 12b. In FIGS. 1 and 2, 22 is a tuning knob, and 23 is a volume knob.

In the earphone housing device 10 having the U-shaped groove 11, the opposite protruding side portions 12a and 12b, and the groove 13 as described above, the cord 3 is pulled out from the cord pull-out hole 15 and is formed on the side surface 21d. U wound around the U-shaped groove 11 (see FIGS. 3 and 4) and then formed on the side surface 21c
It is wound around the V-shaped groove 11 (see FIG. 5), and subsequently, FIG.
U-shaped groove 11 on side surface 21b and side surface 2 as shown in FIG.
It was wound around the U-shaped groove 11 of 1a, and the above-mentioned winding was performed three times on all side surfaces in the same manner. FIG. 6 is a diagram schematically showing a method of winding the cord, and it can be seen that the cord 3 is wound along the U-shaped groove bottom portion 11a.

When the earphone 2 is slid to the side surface 21a after the cord 3 is wound, the earphone 2 presses the protrusion 24 and the opposite protrusions 12a and 12b are slightly elastically deformed. When the earphone 2 is completely stored, the protrusion 24
The earphones 2 are separated from each other, and the opposing protrusions 12a and 12b are returned to the original state. Then, the earphone 2 is formed by the protrusion 24.
Is held in position so as not to come off from the opposed protrusions 12a and 12b. By doing so, a click feeling can be obtained, so that it is possible to confirm that the earphone 2 is stored, and the earphone 2
Can be prevented from falling off the storage device 10.

In this example, the U-shaped groove bottom portion 11a is a flat portion as particularly shown in FIG. The length of the cord stored in the earphone storage device 10 as in this example is 3 cords.
It is preferable from the viewpoint of preventing damage that the length of the end of winding (including the earphone 2) is set to end just on the upper surface of the main body. In this example, the number of turns is three, but various changes such as two, four, and so on can be made.

FIG. 7 and FIG. 8 are views for explaining another embodiment of the present invention and an enlarged view of the principal part taken along the line II--II of FIG. 7, respectively. The parts shown in FIGS. 7 and 8 correspond to the parts shown in FIGS. 3 and 4.

As shown in FIG. 7 and FIG. 8, in this embodiment, two cord guides 17 are provided along the groove 11 at the bottom 11a of the U-shaped groove 11 so that the width is almost the same as the cord width. The groove 3 is formed so that the cord 3 can be easily wound around both sides of the guide 17. The surface forming the cord guide 17 is the entire side surface 21a of the main body 21.
It does not need to be 21d, and when it is formed on the 21d surface as in this example, it may be formed in the U-shaped groove 11 on the facing 21b surface.

The height of such a cord guide 17 is substantially the same as the side surface 21d of the main body 21 as shown in FIG. At this time, the cord 3 has the side surface 21d and the cord guide 1.
It is designed so that it does not protrude beyond the end.

In the embodiments, the case where the present invention is applied to a radio has been described, but the present invention can also be applied to a device using earphones such as a headphone stereo. Further, since an earphone used for a headphone stereo or the like is composed of a pair of earphones for the right channel and the left channel, in this case, two earphone housings may be provided.

[0021]

As described above, according to the present invention, the cord is wound around the entire circumference of the side surface of the main body so as not to project outside. Therefore, even when the main body is stored in the bag or the like, the cord does not collide with or scrape against other objects, and the disconnection can be prevented. Further, since the groove can be formed when forming the main body, it can be easily realized and the cord can be stored without making the main body so large.
