DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is directed to a keyboard installation plate which is installed over an L-shaped corner on a top plate, and a conductive mat is provided on a plate body at least in a space closer to a user than a keyboard installation position. Are placed so that they are electrically connected to the conductive mat and do not come into contact with the top plate near the center of the lower part on the user side of the plate body when the plate body is laid on the L-shaped corner portion. Since a discharge element capable of corona discharge is provided in the air, static electricity accumulated in the user's body when the keyboard is used is discharged from the discharge element through the conductive mat from the discharge element without air in the air. It becomes possible.

In order to improve appearance and enhance the discharge effect, it is preferable that the conductive mat and the discharge element are surface-connected via a metal plate penetrating the plate body. Furthermore, in order to reliably perform corona discharge in air even at a low voltage, it is desirable that the discharge element has a brush shape made of conductive fibers.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 6, the keyboard installation plate of this embodiment is used by being laid across an L-shaped corner 2 on an L-shaped desk top 1. As shown in FIGS. 1 to 5, the keyboard mounting plate is a conductive mat 4 laid on the plate body 3 in a space closer to the user than the keyboard installation position 3S.
When the plate body 3 is electrically connected to the conductive mat 4 and the plate body 3 is erected at the L-shaped corner portion 2, the desk top plate 1 near the center of the lower surface of the plate body 3 on the user side is provided.
And a discharge brush 5 which is a discharge element disposed at a portion not in contact with the discharge brush.

In this embodiment, the plate body 3 is composed of a surface material 31 and a core material 32 which is in close contact with the bottom surface thereof.
In the space on the user side from the keyboard installation position 3S,
To lay the conductive mat 4, the surface material 31 of the space
The conductive mat 4 is inserted into the hollowed part,
The core material 32 and the conductive mat 4 are bonded. As shown in FIGS. 1 and 5, at this time, a copper foil 6 serving as a metal plate is sandwiched between the conductive mat 4 and the core material 32 to electrically connect the conductive mat 4 and the copper foil 6 to each other, and to form a plate body. 3, a core material 32 is pierced in the vicinity of the center of the user side.
When the discharge brush 5 is adhered to the lower surface of the core near the hole, the copper foil 6 is sandwiched between the discharge brush 5 and the core 32, and the discharge brush 5 and the copper foil 6 are electrically connected. As a result, the conductive mat 4 and the discharge brush 5 are electrically connected to each other via the copper foil 6. The discharge brush 5 has a brush body 51 on the lower surface of the copper plate 52.
The brush body 51 is made of conductive fiber. Note that such a configuration is similarly employed whether the plate body 3 is made of metal or plastic.

With such a configuration, the user's hand or finger of the computer 8 slides on the desk top plate 1 or the like by operating the keyboard 7 or the like, so that the user is charged and charged with static electricity. However, when the conductive mat 4 is touched, electric charges are discharged from the discharge brush 5 via the copper foil 6. In particular, since the brush body 51 of the discharge brush 5 is made of conductive fibers, it is possible to discharge corona into the air even at a low voltage from the tip of the brush body 51.

As described above, according to the present embodiment, it is possible to discharge the static electricity accumulated on the user's body from the discharge brush 5 via the conductive mat 4 when using the keyboard 7 without using a discharge cable. . In particular, since the conductive mat 4 and the discharge brush 5 are electrically surface-connected via the copper foil 6, the electric resistance is small, and the discharge is smaller than that when the electric cable for discharge is connected to the plate body 3. In addition to the high effect, the electric cable does not crawl on the desk top 1 or the electric cable does not hang down from the lower surface of the plate body 3, so that the desk top 1 can be used effectively,
Eliminates problems such as the cables getting caught on the feet. Further, the discharge brush 5 is attached to the lower surface of the plate body 3, and the copper foil 6 connecting the discharge brush 5 and the conductive mat 4 is also disposed on the lower surface of the conductive mat 4. At the same time, since these are integrated with the plate main body 3, there is also an effect of being simple when moving. In this embodiment, since the conductive mat 4 is laid in a space closer to the user than the keyboard installation position 3S, it is possible to add a function of a wrist rest to the conductive mat 4.

The present invention is not limited to the embodiment described above. For example, the connection between the conductive mat 4 and the discharge brush 5 can be directly bonded using a conductive adhesive or the like, and the discharge brush 5 is formed in a different shape for the purpose of lowering the discharge voltage. No problem. Also,
In the above embodiment, the conductive mat 4 is arranged on the plate body 3 and the discharge brush 5 is arranged below the plate body 3.
Although the conductive mat 4 and the discharge brush 5 were connected via the copper foil 6, as shown in FIG. 7, a conductive mat 40 such as a conductive vinyl leather was disposed on the entire surface of the plate body 3.
The front edge of the conductive mat 40 may be wound to the lower part of the front end of the plate body 3, and the discharge brush 5 may be directly attached to the conductive mat 40. By doing so, it is not necessary to provide a through hole in the plate body 3 and copper foil is not required. Such a configuration is the same whether the plate body 3 is made of metal or plastic.

In addition, the configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0013]

The present invention is embodied in the form described above and has the following effects. The keyboard installation plate according to the present invention is a conductive mat laid on the plate body in a space on the user side from the keyboard installation position, and is electrically connected to the conductive mat.
In addition, when the plate main body is installed at the L-shaped corner portion of the top plate, a discharge element capable of corona discharge is provided in the air at a position below the plate main body so as not to contact the top plate. The static electricity accumulated in the body can be discharged from the discharge element via the conductive mat when using the keyboard, without using a discharge cable. As a result, the electric cable does not crawl on the desk top plate or the electric cable hangs down from the lower part of the plate as compared with the case where the electric cable for discharge is connected to the plate. Because it is placed in a position that is not visible when using the lower part, it looks good and you can use the desk top plate effectively, eliminating problems such as cables getting caught on your feet, and also when moving and installing this plate In addition, since the discharge function is integrally provided, there is an effect of being simple. And
By laying the conductive mat in a space closer to the user than the keyboard installation position, it is possible to add the function of a wrist rest to the conductive mat. In particular, the conductive mat and the discharge element penetrate the plate. If they are surface-connected via a metal plate, the electric resistance is reduced and the metal plate is hidden inside the plate, so that the appearance is improved and the discharge effect is enhanced.

Further, if the discharge element has a brush shape made of conductive fibers, it is possible to reliably discharge static electricity to the corona even in a low voltage.
