Description

Regarding a pen with a light that can illuminate the area around the pen tip.

There is a demand for a pen with a light that can write letters in a slightly dark place.

When writing a letter with a pen, it was difficult to see the characters to be written because the pen tip and the surrounding area were dark.
An object of the present invention is to provide a pen with a light that illuminates a wide area around the pen tip.

A pen with a light having a main body 2, a light portion 3, a pen mounting portion 4, and a pen 5.
The main body 2 includes a light storage portion 21, a transparent disk-shaped pen support portion 23 provided with a mounting hole 231 for inserting the rear end portion 54 of the pen, and a light diffusing portion 22 for diffusing light. Prepare,
The light unit 3 has a columnar shape and includes a light body 32 for accommodating a battery and a light irradiation unit 31 for illuminating light downward from the tip portion.
The pen mounting portion 4 is a transparent lid 41 that is fitted into the light diffusing portion 22, and is a protruding pen insertion portion having a hole 421 for inserting the pen tip portion 51 from the inside (main body side) in the center of the lid. With 42
The pen 5 is a core of a ballpoint pen and includes a pen tip portion 51, an ink portion 52, and a pen rear end portion 54, and the ink portion has a larger diameter than the pen tip portion 51 and the pen rear end portion 54 .
The pen 5 is used by inserting the tip of the pen into the hole 421 of the pen attachment portion 4 and inserting the rear end portion 54 of the pen into the hole 231 of the pen support portion 23 to attach and use the pen 5.
The light emitted from the light irradiation unit 31 spreads through the transparent pen support portion 23 and the light diffusing portion 22, and further illuminates the periphery of the pen 5 through the transparent lid 41. ..

The diameter of the light diffusing unit 22 is larger than the diameter of the light irradiation unit 31, and the pen is characterized in that the light from the light irradiation unit 31 is spread around the pen tip.

A pen with a light that features a black paint on the outside of the pen insertion part 42 to make it less reflective and make the pen tip easier to see.

Even if the room is dark, the area around the pen tip can be illuminated brightly and widely, making it easier to see before and after the characters you are writing, making it easier to write.

As shown in FIG. 4, the present invention is a pen with a light capable of writing a sentence while illuminating the surroundings of the pen tip even when the room is dark.

FIG. 1 shows the external configuration of the pen with a light of the present invention, and FIG. 2 shows the internal configuration (perspective view) thereof. FIG. 3 shows an internal configuration (AA cross section of FIG. 1).
As shown in FIGS. 1 to 3, the pen with a light of the present invention includes a main body 2, a light portion 3, a pen mounting portion 4, and a pen 5.
The main body 2 has a light storage portion 21, a transparent disk-shaped pen support portion 23 provided with a mounting hole 231 for inserting an end portion different from the tip of the pen, and a columnar or conical shape for diffusing light. The trapezoidal light diffusing unit 22 is integrally configured.
It is preferable that the inner surface of the light diffusing portion 22 is roughened so that the light is reflected and the light is easily diffused, or surface treatment such as coating, plating, or painting is performed.
The light unit 3 is columnar and includes a light main body 32 for accommodating a battery, a light irradiation unit 31 that illuminates light downward from the tip portion, and a handle 33 that can be turned on by pushing it in.
The pen mounting portion 4 is a transparent lid 41, provided with a protruding pen inserting portion 42 having a hole 421 for inserting the pen 5 from the inside (main body side) in the center of the lid, and around the lid. It is provided with an edge for fitting into the light diffusing portion 22.
Although the lid 41 is transparent, it may be matted to soften the passing light.
The pen 5 is a core of a ballpoint pen sold on the market, and includes a pen tip portion 51, an ink portion 52, and a pen rear end portion 54. The ink portion 52 has a slightly larger diameter than the pen tip portion 51 and the pen rear end portion 54, and there is a slight step 53 between the pen tip portion 51 and the ink portion 52, and the pen rear end portion 54 and the ink portion 52. (See FIG. 3).
The light unit 3 has a columnar shape, and has a light body 32 that houses the battery, a light irradiation unit 31 that illuminates light downward from the tip, and a switch that makes it easy to pull in and out of the body 2 and turns on the power by pushing it in. It is a handle 33 that doubles as a handle.

The diameter of the cross section of the light diffusing portion 22 is larger than the diameter of the light irradiating portion 31 at any place so that the light from the light irradiating portion 31 spreads around the pen tip, and a shadow is cast on the pen tip and its surroundings. I try not to do it at all.

The outside of the tip of the pen insertion portion 42 is painted black or matted to make the light less reflective and make the pen tip easier to see.

Hereinafter, a method of using the pen with a light of the present invention will be described.
The light portion 3 is inserted and attached to the light storage portion 21 of the main body 2 from above.
The pen 5 is a core of a commercially available ballpoint pen, and the tip of the pen is inserted into the hole 421 of the pen mounting portion 4 from the inside of the main body 2 until it comes into contact with the step 53.
After inserting the tip portion 51 of the pen, insert the rear end portion 54 of the pen into the hole 231 of the pen support portion 23 up to the step 53, attach the pen, push the lid 41 into the main body to assemble the pen, and then insert the pen. Fix it so that it does not move.
The light emitted from the light irradiation unit 31 spreads in a conical shape through the transparent pen support portion 23 and the light diffusing portion 22, and further illuminates the periphery of the pen 5 through the transparent lid 41.

We provide a pen with a light that allows you to write by illuminating the area around the pen tip.
