DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial fingertip having an electric conductor, which enables an image position pointing device of a notebook computer to be operated by the artificial fingertip.

[0002]

2. Description of the Related Art The inventor of the present invention has disclosed Japanese Patent Application No. 11-334.
211, for the first time, disclosed a new technical idea of artificial fingertips. It is a fingertip on the back of the nail to eliminate various obstacles caused by long straight nails and artificial nail tips, such as scratching the scalp when shampooing and not hitting the key of the PC quickly. A molded artificial fingertip is to be worn. However, artificial fingertips made of thermoplastics and the like use an image position pointing device (tracking device) called a trackpad, which is installed in notebook computers such as Apple's PowerBook and NEC and Fujitsu. A significant drawback was that it could not be moved. By the way, a trackpad that operates by tracing a flat surface with a fingertip detects the vertical and horizontal movement of static electricity emitted from a human fingertip by the change in capacitance of the two-layer thin film capacitor, and detects this by the movement of the cursor. Is converted to

SUMMARY OF THE INVENTION An object of the present invention is to operate an image position pointing device of a notebook computer using a long nail such as an index finger or a middle finger or an artificial finger head attached to an artificial nail. What measures should be taken to make this happen?

[0004]

According to the present invention, in order to solve the above-mentioned problems, an electric conductor that conducts static electricity generated from a human fingertip is attached to an artificial fingertip. By doing so, the trackpad, which is the image position pointing device of the notebook computer, operates smoothly, so that the cursor on the screen can be easily and reliably moved by the finger wearing the artificial fingertip.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION An artificial fingertip with an electric conductor according to the present invention has one end of the electric conductor in close contact with the skin of the fingertip of the index finger or the middle finger used when operating a track pad, The other end of the object protrudes from the tip of the artificial fingertip to trace the surface of the trackpad.

As the electric conductor used in the present invention, a small-sized alkaline button battery, lithium battery, or the like is preferable. When the length of the artificial fingertip is 20 mm or more, a dry cell such as a AAA battery is preferably used. Alternatively, instead of the battery, an electrically conductive resin such as a polyacrylonitrile pyrolyzate, polyacetylene, polycopper phthalocyanine, polyvinyl anthracene iodine, and polyvinylpyridine tetracyanoquinodimethane can also be used. Alternatively, an artificial fingertip dedicated to a track pad may be manufactured using these electrically conductive resins as materials.

FIG. 1 is a side view showing one embodiment of an artificial fingertip 1 having an electric conductor according to the present invention. Alkaline button cell 2 having a diameter of 7 mm and a thickness of 3 mm as electric conductor 2
You are using Then, the positive pole of the first alkaline button battery is projected into the fingertip fitting portion 3 so that the fingertip T comes into close contact with the positive pole. Also, the negative pole of the second alkaline button battery is made to protrude outside the artificial fingertip abdomen 4,
It traverses the surface of the trackpad on notebook computers. Although the projection angle of the minus pole surface is not particularly limited, it is easier to trace the track pad if the long nail N is arranged as parallel as possible.
Note that the number of alkaline button batteries to be used can be arbitrarily increased or decreased depending on the length of the artificial fingertip 1, since the static electricity conduction effect of the battery is the same whether it is one or three.

FIG. 2 is a side view showing another embodiment of the artificial fingertip 1a having the electric conductor of the present invention. In this embodiment, the electric conductor 2a has a diameter of 11 mm and a length of 29 mm.
A single 5 mm dry cell battery is used, which is arranged behind the long nail N. Then, insert the positive pole of the dry battery
, So that the fingertip T is in close contact with the plus pole, and the minus pole is projected from the tip of the artificial fingertip 1a. By doing so, it is possible to hit the keys of the personal computer with the minus pole of the dry battery, and to freely move the cursor on the screen by operating the trackpad.

[0009]

As described above, the artificial fingertip having the electric conductor of the present invention conducts the static electricity generated from the fingertip to the track pad which is the image position indicating device of the notebook computer. For this reason, the track pad operated by the static electricity can be reliably operated by the artificial fingertip attached to the back of the nail of the index finger or the middle finger. Therefore, the cursor on the screen can be freely moved by the finger wearing the artificial fingertip.
