Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic device in which a power cord of the electronic device or a cord for connection to another device is stored in a cord storage section provided in a housing of the electronic device. The present invention relates to a cord storage structure.

[Prior Art] In order to keep the power cord of an electronic device or the cord for connecting it to other devices together when not in use, some electronic devices have a structure in which a protrusion is provided on the housing and the cord is wrapped around the protrusion. There is. However, this structure has the disadvantage that the cord is forced to bend with a small radius of curvature due to the protrusion, which shortens the life of the cord. It also looks bad.

Therefore, especially in portable electronic devices, a structure in which a cord storage section is provided in the housing is often used. The simplest of these cord storage structures is one in which a lid is simply provided at the entrance for loading and unloading cords into a hollow cord storage section. Furthermore, as a more sophisticated structure, a cord reel type structure is also adopted, in which a reel for winding the cord is provided inside the cord storage section.

[Problems to be Solved by the Invention] However, in the above-mentioned structure in which only the lid is provided, the lid must be opened and closed each time the cord is inserted or taken out.

Furthermore, when storing the cord, if the user does not fold the cord properly, the cord may not fit properly, or the cord may be damaged by forcing it in.

Further, the cord reel type has a disadvantage in that it has a complicated structure and is expensive, and requires a large space in the storage section.

Therefore, an object of the present invention is to provide a structure that can be implemented easily and inexpensively, and that allows cords to be inserted and removed easily and smoothly.
To provide a cord storage structure for an electronic device that can properly store the cord without strain.

[Means for Solving the Problems] In order to solve the above problems, according to the present invention, the power cord of the electronic device or the cord for connection with other devices is placed in the cord storage section provided in the housing of the electronic device. In a cord storage structure for an electronic device to be stored, a pair of rollers are provided at an entrance through which a cord is taken in and taken out of the cord storage section so as to be able to rotate while holding the cord between the rollers, and the cord passes between the rollers and enters the cord storage section. We adopted a structure that allows it to be put in and taken out.

[Function] According to this structure, the cord can be smoothly taken in and out of the cord storage portion sequentially along the length of the cord while rotating the roller. Further, when the cord is stored, the roller functions as a lid that prevents the cord from protruding from the cord storage section.

[Example] Hereinafter, details of embodiments of the present invention will be described with reference to the drawings.

First Embodiment FIGS. 1 to 3 illustrate a cord storage structure for an electronic device according to a first embodiment of the present invention.

In FIGS. 1 to 3, reference numeral 1 denotes a housing case of an electronic device, and a cord storage part 9 for storing a cord (for example, a power cord) 4 is provided in a predetermined part of the case 1, for example, on the back side. ing.

The base end of the cord 4 is connected to the cord storage section 9 through the bushing 5.
It is connected to an unillustrated circuit of electronic equipment through the back wall. The cord 4 is folded and stored in the cord storage part 9, or is pulled out from the cord storage part 9 and used by inserting the plug 8 connected to the tip into an outlet (not shown).

A pair of rollers 2.2 are provided at the entrance 9a through which the cord 4 of the cord storage section 9 is taken in and taken out, which is different from the conventional cord. The rollers 2.2 are rotatably supported by a rotating shaft 3.3 and are arranged perpendicular to the floor plate of the cord storage section 9 and parallel to each other.

It is preferable that at least the outer peripheral portion of the roller 2.2 is made of an elastic material such as rubber. Further, the interval between the rollers 22 is made slightly smaller than the thickness of the cord 4, and the cord 4 is inserted between the rollers 2.2 and held between the rollers 2.2.

The cord 4 is passed through the cord storage section 9 between the rollers 2 and 2.
It is taken in and taken out from. That is, when storing the cord 4, the cord 4 is pushed in the direction of arrow a in FIG. As a result, the roller 2.2 holding the code 4
The cord 4 rotates in the direction due to friction with the cord 4, and the cord 4 is smoothly fed sequentially from the proximal end side in the direction a along the length direction.

As shown in FIG. 3, a plug accommodating part 6, which is a recess shaped like the plug 8, is provided below the entrance 9a of the cord accommodating part 9. As described above, by pushing the cord 4 in the direction of the arrow in FIG. 1, the plug 8 moves to the roller 2.
When it comes near 2, put the plug 8 into the plug storage part 6 and store it.

When using the cord 4 from the stored state, remove the plug 8 from the plug housing 6 and pull the cord 4 in the direction indicated by the arrow in FIG.
According to this embodiment, in which the cord 4 is smoothly pulled out sequentially from the tip side as the cord 2 rotates in the direction B, when the cord 4 is inserted into or taken out from the cord storage section 9, the cord 4 is pulled out from the roller 2. .2, and it can be smoothly taken in and taken out sequentially along its length. Therefore, there is no possibility of damaging the cord 4 by applying excessive force to it when taking it in or out. In addition, the user does not have to fold the cord 4 when storing it as in the conventional case, and the cord 4 can be easily stored. Further, when the cord 4 is pulled out, the cord 4 does not get tangled, and the bow can be easily pulled out.

Further, according to this embodiment, the roller 2.2 functions as a lid that prevents the cord 4 from protruding from the cord storage portion 9 when the cord 4 is stored. There is no need to open and close the lid every time the cord is inserted or taken out, unlike in the case of the conventional structure in which a cord storage section is provided with a lid.

Furthermore, the structure of the cord storage section of this embodiment has no lid, and only the roller 2.2 is provided instead, making it an extremely simple structure and can be implemented at low cost.

Next, another embodiment in which the structure of this embodiment is modified will be described with reference to FIG. 4 and subsequent figures.

Second Embodiment FIG. 4 shows the structure of a cord storage section according to a second embodiment. As shown in the figure, in this embodiment, the width of the entrance 9a of the cord storage section 9 is narrower than that in the first embodiment. The distance between the side wall 1a of the entrance 9a and the roller 2.2 is smaller than the thickness of the cord 4.

According to such a structure, the cord 4 is stored in the cord storage section 9.
The cord 4 does not protrude from the gap between the side wall 1a and the roller 2 in the stored state. It also improves the appearance.

Third Embodiment Next, FIGS. 5A, 5B and 6 show a roller 2.2 of a cord storage section according to a third embodiment of the present invention.

As shown in these figures, in this embodiment a gear 7.7 is provided at the lower end of the roller 2.2. The gears 7 are each provided integrally with the roller 2, and are meshed with each other as shown in FIG. 5(B).

According to such a structure, the rollers 2, 2 are interlocked by the meshing of the respective gears 7.7 and rotate in the same phase with each other, so that the cord 4 can be taken in and taken out more smoothly and stably.

Further, as shown in FIG. 6, in this embodiment, a guide groove 2a for guiding the cord 4 is formed on the outer periphery of the central portion of the roller 2.2. Guided by the guide groove 2a, the cord 4 can be taken in and out more stably and smoothly.

Fourth Embodiment Next, FIGS. 7A and 7B show rollers 2, 2 according to a fourth embodiment of the present invention. In this embodiment, the cross-sectional shape of the geared roller 2 of the third embodiment (the cross-sectional shape perpendicular to the rotation axis of the roller 2) is modified into an elliptical shape. Also,
Here, as shown in FIG. 7(A), the gears 7.7 are meshed with each other in such a phase relationship that the longitudinal directions of the rollers 2, 2 are sometimes perpendicular to each other.

According to this embodiment, as shown in FIGS. 7(A) and 7(B), the distance between the rollers 2.2 does not change depending on the rotation angle of the rollers 2.2, but the position of the distance, that is, the code 4 The pinching position changes along the C direction (direction connecting the rotating shafts 3 of the rollers 2.2) orthogonal to the a and b directions of the cord insertion and removal directions. Therefore, when the cord 4 is put into the cord storage section 9, the cord 4 is swung in the C direction and put in the A direction, and is stored while being folded in a regular and orderly manner.

That is, according to this embodiment, the cord 4 can be folded and stored in a more orderly manner, and the storage space of the cord storage section 9 can also be smaller.

Note that the shape of the cross section perpendicular to the rotation axis 3 of the roller 2 is as follows.
Of course, the shape is not limited to the circular shape of the third embodiment and the elliptical shape of this embodiment.
