DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic view of a laptop personal computer having an openable panel as an example to which the present invention is applied. Parts corresponding to those in the conventional example of FIG. 12 are denoted by the same reference numerals, and description thereof is omitted. Here, the openable panel 1 has a structure in which the lower side of the back surface thereof is brought into contact with the main body 2 and locked when used. That is, the conductive material provided on the lower panel 4 of the openable panel 1 abuts on the conductive material (cushion 6) provided on the main body 2 at the contact portion 11 located between the rotating portions 9 and 10. The openable panel 1 is supported by the main body 2 at an angle.

FIG. 2 is a schematic side view of a side surface of the laptop personal computer shown in FIG. A conductive material 5 is provided between the rotating parts 9 and 10 of the lower panel 4 of the openable panel 1, and a conductive material (cushion 6) is provided on the main body 2 at a position corresponding to the conductive material 5. When the openable panel 1 is opened and hits the main body 2, the conductive material 5 and the cushion 6
And the opening / closing panel is supported by the main body 2 and keeps the same state.

The conductive material 5 is connected to conductive surfaces for preventing unnecessary radiation provided inside the lower panel 4 and the upper panel 3, and the cushion 6 is provided inside the main body 2. The conductive surface of the main body 2 is connected to a power supply 12 in the main body 2.
Is connected to a zero potential portion (earth line) 13 connected to the power supply.

With such a configuration, in the laptop personal computer of the present embodiment, the conductive material 5 and the cushion 6 are surface-connected, so that the conductive surface inside the openable panel 1 for preventing unnecessary radiation is provided. Is connected to the zero potential portion in the main body 2 with low impedance, and as a result, electromagnetic noise radiated from the openable panel 1 is reduced.

Next, with reference to FIGS. 2 to 11, an electronic apparatus having the openable panel according to the present invention and a method for reducing electromagnetic noise from the openable panel will be described in detail.

FIG. 3 shows an external view of the lower panel 4 of the openable / closable panel 1. As a material of the lower panel 4, a metal material such as a magnesium alloy or a synthetic resin material is used. In any case, the shape of the lower panel 4 is the same. First, the lower panel 4 using a metal material will be described.

The appearance surface (painted surface) 14 is an outer surface of the lower panel 4, that is, a surface that can be seen from the outside, and is painted to make it look better. The appearance surface (painted surface) 14 has no electrical continuity since it is painted.

The back surface (masking surface) 15 is a surface inside the lower panel 4 that cannot be seen from the outside, that is, a surface corresponding to the back surface of the appearance surface (painted surface) 14. The back surface (masking surface) 15 is masked when painting the appearance surface (painted surface) 14 so that the paint does not adhere to the appearance surface (painted surface) 14 for the purpose of not requiring an external appearance and conducting electric conduction. It has become. As described above, the back surface (masking surface) 15 of the appearance surface is electrically connected to the appearance surface (painted surface) 14 because the masking is performed at the time of painting. The back of this appearance (masking side) 1
Reference numeral 5 denotes a conductive surface for preventing unnecessary radiation.

The connecting posts 16 are composed of the lower panel 4 and the upper panel 3.
Are fixed together and electrically connected to each other. The connecting posts 16 are provided at corresponding positions on the upper panel 3.
Are provided, each of which is fixed by screws.

The electrical connection between the lower panel 4 and the upper panel 3 is not limited to the connection column 16, but is not shown, but is not limited to the steps provided at the edges of the lower panel 4 and the upper panel 3. It is also done by meshing.

The conductive material fixing portion 17 is a portion located between the rotating portions 9 and 10 on the lower panel 4 side corresponding to the contact portion 11 where the above-mentioned openable panel and the main body 2 come into contact with each other. The conductive material described later is fixed.

Next, the lower panel 4 when a synthetic resin material is used will be described. The appearance surface 14 is made of a synthetic resin material as it is or is painted, and of course, there is no electrical conduction.

The entire back surface 15 of the appearance surface is coated with a conductive paint, which is used as a conductive surface for preventing unnecessary radiation. When the conductive paint is applied to the back surface 15 of the appearance surface, the appearance surface 14 is masked in order to prevent the conductive paint from adhering to the appearance surface 14. The description of the other parts of the lower panel 4 when the synthetic resin is used is the same as that in the case where the above-described metal material is used, and a description thereof will be omitted.

The provision of the conductive material 5 connected to the conductive surface for preventing unnecessary radiation on the lower panel 4 having the above configuration will be described. FIG. 4 shows the conductive material fixing portion 17 of the lower panel 4.
FIG. 4 is a cross-sectional view as viewed from the direction A shown in FIG.

FIG. 4 shows a case where a metal material is used for the lower panel 4.
This shows a case where a conductive tape 18 which also has a function of a connecting member for electrically connecting the conductive tape and the conductive surface is used.

The conductive tape 18 is attached to the lower panel 4 including the end face of the lower panel 4, over the appearance surface (painted surface) 14 and the back surface (masking surface) 15 of the lower panel. (For example, product name: Co-Foil, manufactured by Taiyo Mesh Co., Ltd.) can be used.

The conductive tape 18 has an organic material such as plastic as its base material, and the tape itself is made conductive by mixing a conductive substance or the like with the base material. Further, as can be seen from FIG. 4, the conductive tape 18 is required to have flexibility since the conductive tape 18 is bent and attached at the end face of the lower panel 4. Here, since the conductive tape 18 is made of an organic material such as plastic, it has flexibility with respect to bending, and the conductive tape 18 itself is not broken or fatigued even when bent at an acute angle.

One surface of the conductive tape 18 (in FIG. 4, the conductive tape 18 is applied to the appearance surface (painted surface) 1 of the lower panel 4).
4 and the back side (the side in contact with the masking surface) 15) are adhesive surfaces, and an adhesive is applied to this adhesive surface. This adhesive has conductivity.
That is, a conductive adhesive is applied to the bonding surface of the conductive tape 18. Therefore, when the conductive tape 18 is attached to a conductive object, the conductive tape 18
Is electrically connected to the base material through a conductive adhesive.

The other surface of the conductive tape 18 (the surface of the conductive tape 18 that is not in contact with the lower panel 4 in FIG. 4) is electrically conductive on the base material of the conductive tape 18 as described above. This other surface will have conduction with the adhesive surface. Therefore, in the conductive tape 18,
The bonding surface side and the surface opposite to the bonding surface have conductivity over both surfaces.

As can be seen from FIG. 4, the conductive tape 18
Are attached from the inside to the outside of the lower panel 4. That is, on the lower panel 4, the conductive tape 18 is applied from the back surface (masking surface) 15 to the appearance surface (painted surface) 1.
4 is pasted.

More specifically, the conductive tape 18
The back surface (masking surface) 15 of the appearance surface is masked and adheres to a conductive surface (conductive surface). On the other hand, the appearance surface (painted surface) 14 is the lower one of the appearance surfaces (painted surface) 14, that is, the appearance surface (painted surface) 14.
Is adhered to the extent that the portion that contacts the main body 2 can be sufficiently covered.

As described above, the conductive tape 18 is attached to the lower panel 4.
The opening / closing panel 1 is attached to the main body 2 by a simple operation of attaching the conductive tape 18 at the edge of the lower panel 4 and attaching the conductive tape 18 also to the conductive material fixing portion 17 while attaching the conductive tape 18 to the back surface (masking surface) 15 of FIG. Contact part (conductive material fixing part 1)
7), the conductive material 5 that is conductive to the conductive surface for preventing unnecessary radiation of the openable panel 1 is easily formed at the portion where the openable panel 1 contacts the main body 2 (conductive material fixing portion 17).

The back side of the upper panel 3 of the openable / closable panel 1 is also masked at the time of painting to form a conductive surface. As described above, the upper panel 3 and the lower panel 4
The conductive surfaces of the upper panel 3 and the conductive surface of the lower panel 4 are electrically connected to each other. As a result, the conductive surface formed so as to entirely cover the openable panel 1 is connected to the conductive material 5.

By using a conductive material having a function of connecting the conductive material 5 and the conductive surface, such as a conductive tape 18, which is flexible against bending, the lower panel 4 can be used.
Even when the conductive material has a complicated curved surface or when the conductive material must be bent at the end face of the lower panel 4, the conductive material is not mechanically broken or fatigued.
Can be attached according to the shape of the surface. Therefore, this conductive material can be firmly fixed to lower panel 4.

By the way, the lower panel 4 made of a synthetic resin material
4, the same conductive tape 18 as in the example of FIG. 4 can be used as the conductive material 5. In this case, even if the material of the lower panel 4 is different, the opening / closing panel 1 is easily and easily attached to the portion (conductive material fixing portion 17) where the opening / closing panel 1 comes into contact with the main body 2 in the same manner as in the example of FIG. The conductive material 5 that conducts to the conductive surface for preventing unnecessary radiation of the panel 1 can be easily formed.

As the conductive material 5 formed on the openable panel 1, in addition to the conductive tape 18, a metal plate 19 such as an aluminum plate as shown in FIG. 5 can be used. Metal plate 1
The cross section of 9 is arcuate along the curved surface of the conductive material fixing portion 17 of the lower panel 4.

FIGS. 6 and 7 show how the metal plate 19 is attached to the lower panel 4. FIG. 6 shows a plurality of metal screws 2
0 fixes the metal plate 19 to the lower panel 4. The conductive surface of the lower panel 4 for preventing unnecessary radiation is a metal screw 2
0 is connected to the conductive material 5 (metal plate 19).

FIG. 7 shows that the metal plate 19 is fixed to the lower panel 4 by the conductive adhesive 21. The contact portion 11 of the lower panel 4 is provided with a plurality of holes 22. The conductive adhesive 21 is attached to the metal plate 19 through the hole 22 from the conductive surface side of the lower panel 4. Thus, the conductive surface of the lower panel 4 for preventing unnecessary radiation is connected to the conductive material 5 (metal plate 19) via the conductive adhesive 21.

Next, a description will be given of how to attach the cushion 6 which is a conductive material on the side of the main body 2 with which the conductive material 5 of the openable panel 1 comes into contact. FIG. 8 shows a state in which the cushion 6 is fixed to the main body 2 made of a metal material.

In FIG. 8, the side of the main body 2 to which the cushion 6 (to be described in detail later) is fixed is a painted surface, and the painted surface is masked. In other words, the surface of the main body 2 to be attached to the cushion 6 has conductivity because the metal material is exposed as it is.

In FIG. 8, cushion 6 (conductive material)
Is made of an organic material such as rubber, and a conductive material such as carbon is mixed in the organic material. Therefore, the cushion 6 itself has conductivity.

One surface of the cushion 6, that is, the main body 2
A conductive adhesive 23 is applied to the surface in contact with the conductive adhesive. Thereby, the cushion 6 is conducted to the conductive surface of the main body 2 for preventing unnecessary radiation.

FIG. 9 shows a state in which the cushion 6 is fixed to a masking portion 24 (a metal material exposed portion formed by applying a mask at the time of painting) of the main body 2. When the cushion 6 is fixed on the main body 2, the outer periphery of the masking portion 24 is located inside the outer periphery of the cushion 6 so that the metal material of the masking portion 24 is not directly visible.

Incidentally, as another method of fixing the cushion 6 to the masking portion 24 of the main body 2, there is a method as shown in FIG. In FIG. 10, both ends of the cushion 6 are fixed to the masking portion 24 by a non-conductive adhesive 25, and the cushion 6 is in direct contact with the metal material of the masking portion at the center. In this case, the openable panel 1 comes into contact with the main body 2, and a portion other than both ends of the cushion 6 is pressed against the exposed metal portion of the masking portion 24, so that a reliable connection is obtained.

The above description is for the case where the main body 2 is made of a metal material. However, when the main body 2 is made of a synthetic resin like the upper panel 3 and the lower panel 4 of the openable panel 1 described above, the following is performed. The cushion 6 is fixed to the main body 2.

FIG. 11 shows a state in which the cushion 6 is fixed to the main body 2 made of a synthetic resin material. Surface 2 of body 2
Reference numeral 6 denotes a surface of the synthetic resin material as it is or a painted surface, and of course, there is no electrical conduction. Appearance back 27
Has an entire surface coated with a conductive paint, which serves as a conductive surface for preventing unnecessary radiation. The cushion 6 is adhered to the appearance surface 26 of the main body 2 with a conductive adhesive 23. A plurality of holes 28 are provided over the entire surface of the body 2 where the cushion 6 is bonded. The hole 28 is filled with a conductive adhesive 29 from the back surface 27 side of the main body 2. Thereby, the cushion 6 is conducted to the conductive surface of the main body 2 for preventing unnecessary radiation.

The cushion 6 has not only conductivity but also the lower panel 4 strongly hits the main body 2 when the openable panel 1 is opened until it comes into contact with the main body 2. It has a role as a cushioning material so that the surface is not damaged. That is, the cushion 6 has a role as a receiver (stopper) for the openable / closable panel 1. Therefore, the cushion 6 (conductive material)
Need to have elasticity.

The conductive material to be attached to the main body 2 is not limited to the cushion 6, but any other material having conductivity and elasticity can be used. Here, by using a conductive material, conduction between the masked portion of the main body 2 and the portion in contact with the lower panel 4 can be provided.

Also, by using a resilient material, when the openable panel 1 is opened and brought into contact with the main body 2 at the time of use, even if the openable panel 1 hits the main body 2 due to a strong force, the openable type is used. The panel 1 and the main body 2 can be prevented from being damaged or damaged, and the conductive tape 18 pasted on the lower panel 4 can be prevented from being damaged or damaged.

Also, by using a material having elasticity as the conductive material, the conductive tape 1 attached to the lower panel 4 can be used.
When the conductive material 8 and the conductive material on the main body side come into contact with each other, the conductive material on the main body side is deformed due to its elasticity and can be dented along the shape of the lower panel 4.
The contact area of the conductive tape 18 can be made larger than when the conductive material on the main body side does not have elasticity.

The structure of the openable panel 1 side and the main body 2 side is as described above. Therefore, the openable panel 1
Is opened and brought into contact with the main body 2, the electrical connection described below is completed. That is, the upper panel 3 and the lower panel 4
Means that the conductive surfaces provided for each are conductive, and the lower panel 4
A portion of the outer surface (conductive surface) 15 and the outer surface (painted surface) 14 that comes into contact with the main body 2 are electrically connected via the conductive material 5, the conductive material 5 and the cushion 6 are electrically connected, and the cushion 6 The conductive surface of the main body 2 is electrically connected to the conductive surface, and the conductive surface is electrically connected to the zero potential portion 13.

Further, in this conduction, the upper panel 3
The conductive surface of the lower panel 4 and the conductive surface of the lower panel 4 are in surface contact with each other, the conductive surface 15 of the lower panel 4 and the conductive material 5 are also bonded in a planar manner, and the conductive material 5 must be wider. As a result, the conductive cross-sectional area can be increased, and the conductive material 5 and the cushion 6 come into surface contact with each other. If the cushion 6 is selected to have an appropriate elasticity, the cushion 6 is dented to further increase the contact area. That the cushion 6 can have a wide width and that the thickness thereof is small, so that the electrical resistance is small and sufficient conductivity can be obtained. Since sufficient adhesion can be obtained because the surface can be adhered, as a result, the openable panel 1 and the main body 2 can be electrically connected while securing a large conductive area.

As described above, in a portable video tape recorder (portable VTR), a laptop personal computer, and other electronic devices, when used, the openable panel is opened until it comes into contact with the main body, and the conductive panel provided on the openable panel is used. The material and the conductive material provided on the main body can be brought into surface contact.

As a result, the electromagnetic noise generated in the openable panel is connected to the zero potential portion (ground portion) of the main body 2 through a wide surface, so that the electromagnetic noise emitted from the openable panel to the outside is greatly reduced. It is possible to take effective measures against unnecessary radiation from the openable panel.

It should be noted that the present invention is not limited to the above-described example, but can adopt various other configurations without departing from the gist of the present invention.

[0064]

The present invention has the following effects. The openable panel has a conductive material that conducts between the part that comes into contact with the main body and the conductive surface for preventing unnecessary radiation, and has elasticity that conducts the part where the main body comes into contact with the openable panel and the zero potential part (earth line). By having a conductive material having, when in use, open the openable panel until it comes into contact with the main body, by bringing the conductive material provided on the openable panel and the conductive material provided on the main body into surface contact by elastic deformation, Since the electromagnetic noise generated in the openable panel is grounded to the main body through a wide surface, the electromagnetic noise emitted from the openable panel to the outside can be significantly reduced.

In addition, since the conductive material of the openable panel has flexibility with respect to bending, the conductive material can be mechanically broken or fatigued even when the conductive material must be bent. There is no. In addition, since the conductive material of the main body has elasticity, the contact area between the conductive material on the main body side and the conductive material on the lower panel can be further increased.
