Abstract

PROBLEM TO BE SOLVED: To light up the tip of an input chip by using a substance which is transparent and has photoconductivity for the input chip provided at the tip of the input pen, and transmitting the light from a light source through the input chip and emitting it from the input chip tip. SOLUTION: The input chip 2 which has a front part 2A almost in a comic shape and a tip 2B formed into a curved surface is engaged threadably with the front part of a shaft cylinder 1 made of an insulating material such as synthetic resin. The input chip 2 is formed of the substance which is transparent and photoconductive. An internal shaft 3 made of an electric conductor is inserted into the front part of the shaft cylinder 1 and a fairy lamp as the light source is fitted to the internal shaft 3. The light of this fairy lamp 4 is transmitted to the input chip 2 and emitted from the tip 2B of the input chip 2. Consequently, the tip of the input chip 2 can be lit up, so the position of the input chip 2 can easily be confirmed on a tablet even in a dark place.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input pen having an illumination function, which is provided with an illumination function for inputting information to a pressure-sensitive handwriting input device.

[0002]

2. Description of the Related Art In a conventional input pen with a lighting function,
A transparent and light conductive light projecting member is provided at the front of the input pen, and light from a light source is transmitted through the light projecting member and generated from the tip of the light projecting member.

[0003]

However, the above-described conventional input pen with a lighting function is convenient for brightly illuminating the entire front portion of the input pen, but the tip of the input tip that contacts the tablet is the input tip. As a result, a shadow is generated, and the tip of the input pen is difficult to see. An object of the present invention is to provide an input pen with a lighting function that solves the above problems.

[0004]

According to the present invention, an input chip provided at the tip of an input pen is made of a transparent and photoconductive substance, and light from a light source is inputted. The point is that the signal is transmitted from the tip of the input chip and is generated from the tip of the input chip.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. 1 and 2, an input chip 2 having a substantially conical front portion 2A and a curved end 2B is screwed into a front portion of a shaft cylinder 1 made of an insulating material such as a synthetic resin. The input chip 2 is made of a transparent and photoconductive material. An inner shaft 3 made of an electric conductor is inserted into the front inside of the barrel 1, and a miniature bulb 4 as a light source is attached to the inner shaft 3. Also, the conductive piece 3 extending in the longitudinal direction of the inner shaft 3
A is a concave groove 1A that extends rearward in the longitudinal direction from the front end of the barrel 1
The contact 3B is formed at the rear end of the conductive piece 3A. A switch 5 made of an electric conductor is rotatably provided at a rear portion of the barrel 1, and a contact 5 </ b> A of the switch 5 is configured to be able to contact and separate from a contact 3 </ b> B of the inner shaft 3. A coil spring 6 made of an electric conductor is provided at the front end of the switch 5, and the coil spring 6 contacts a cathode 7 </ b> A of a dry battery 7 built in the barrel 1 to urge the dry battery 7 forward. The anode 7B is brought into contact with the rear end of the miniature lamp 4. When the miniature bulb 4 of the input pen with lighting function is turned on, the switch 5 is turned to the right by a half turn to bring the contact 5A of the switch 5 into contact with the contact 3B of the inner shaft 3 to obtain the state shown in FIG. . Then, the light of the miniature bulb 4 propagates through the input chip 2 and is generated from the tip 2B of the input chip 2. When the miniature bulb 4 is turned off, the switch 5 is turned half a turn to the left to separate the contact 5A of the switch 5 from the contact 3B of the inner shaft 3. When replacing the dry battery 7, the input chip 2 is removed from the barrel 1, and the dry battery 7 is taken out together with the inner shaft 3. Thereafter, a new dry cell 7 is inserted together with the inner shaft 3 and the shaft cylinder 1 is inserted.
The input chip 2 is screwed.

In the input pen with illumination function according to the first embodiment, since light is generated from the entire input chip 2 including the tip 2B of the input chip 2, the vicinity of the tip of the input chip 2 and the periphery of the input chip 2 are brightened. Can illuminate,
Input chip 2 on tablet easily even in dark place
The position of can be confirmed. Therefore, the input can be performed by pressing the tip 2B of the input chip 2 to an accurate position of the tablet of the pressure-sensitive handwriting input device.

FIG. 4 shows a second embodiment of the present invention, in which a cap 8 for protecting the input chip 2 is provided at the front of the shaft cylinder 11. The cap 8 is provided with a clip 9 and can be carried by being inserted into a pocket of clothes or the like. When performing an input operation, the cap 8 is attached to the rear part of the barrel 11.

FIGS. 5 and 6 show a third embodiment of the present invention. First, an input state in which the illumination of FIG. 5 is turned on will be described. A light projecting member 10 made of a transparent and photoconductive material is screwed into a front portion of the barrel 1. A rear shaft portion 12C of the input chip 12, which is made of a transparent and photoconductive material, is fitted and attached to the distal end hole 10A of the light projecting member 10. The front portion 12A of the input chip 12 has a substantially conical shape and the tip 12B is formed in a curved surface. The rear end 12D of the input chip 12 is formed flat.

Accordingly, the light of the miniature bulb 4 is transmitted through the light projecting member 10 and the input chip 12, and is generated from the periphery of the light projecting member 10 and the tip 12B of the input chip 12.

Normally, as shown in FIG. 6, the front shaft 12E of the input chip 12 is
If it is made to fit, the tip 12B of the input chip 12 will be protected and can be used as a flashlight.

[0011]

According to the input pen with illumination function of the present invention described above, the tip of the input chip can be brightly illuminated by the light generated from the tip of the input tip after passing through the input chip. Therefore, the position of the input chip on the tablet can be easily confirmed even in a dark place, and the effect of reliably performing the input operation in the dark place can be obtained.
