Abstract

PROBLEM TO BE SOLVED: To obtain a writing instrument with an illuminator for simply writing by illuminating a nib part in case of writing in emergency in a dark place by detachably mounting a transparent cover at an end of a bar-like flashlight and forming a transparent pen mounting part integral with a cover at an end of the cover. SOLUTION: A transparent cover 2 is detachably mounted at an illumination light side of an end of a bar-like flashlight 1. A transparent pen mounting part 3 integral with a cover 2 is formed at an end of the cover 2. A barrel 5 of a writing instrument such as a ballpoint pen is detachably inserted fixedly into a receptacle 4 perforated at the part 3, thereby manufacturing the instrument with a light. With such a constitution, a nib direction is illuminated through the cover 2 and the part 3 by an illumination of the flashlight 1. Thus, the instrument can easily and simply write even in a dark place at night and simultaneously commonly has a function of the flashlight. Particularly, when the part 3 is remarkably radially reduced as compared with the cover 2, a light converging action is obtained at the part 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument such as a ballpoint pen, a fountain pen, a writing pen, etc., and a writing instrument with a light capable of writing without any trouble even in a dark place because a light is illuminated around the pen tip. Is.

[0002]

2. Description of the Related Art Writing instruments such as ball-point pens and fountain pens that have been used in the past have been remarkably improved in function.
There is no writing instrument that allows writing in a dark place such as at night.

[0003]

Conventional writing instruments such as ballpoint pens and fountain pens do not have a means for illuminating the pen tip portion, so when writing characters in a dark place, use a flashlight or an automobile light to assist the illumination. It will be difficult to write letters without such lighting means,
It is very inconvenient to write in an emergency in a dark place for some reason.

It is an object of the present invention to provide a writing instrument with illumination that enables the pen tip portion to be illuminated in such a case and allows easy and simple writing.

[0005]

In order to achieve the above-mentioned object, the present invention detachably mounts a transparent cover 2 on the tip of the rod-shaped flashlight 1, that is, on the side of the illumination light, and attaches it to the tip of the cover 2. A pen mounting portion 6 which is also made of a transparent body and is integral with the cover 2 is formed, and a shaft 5 of a writing instrument such as a ballpoint pen is detachably inserted and fixed into an insertion hole 4 mounted in the pen mounting portion 3. The pen mounting portion 6 of the cover 2 has a diameter remarkably smaller than that of the cover 2, and the pen mounting portion 3 is tapered from the cover 2 so as to project thinly.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A specific structure of the present invention will be described with reference to the drawings. 1 is a rod-shaped flashlight, and in consideration of ease of use, a slender flashlight with high illumination power is used as much as possible. The tip part of the flashlight 1 is formed in a polygonal shape. The cover 2 which is a transparent body made of a molded product such as a reinforced plastic which is detachably attached to the tip of the flashlight 1 has the inner surface of the fitting portion formed into a polygonal surface corresponding to the tip of the flashlight 1. The cover 2 is designed so as to prevent the cover 2 from rotating when it is mounted, and the cover 2 is prevented from coming off by making the fitting itself into a tight fit.
The pen mounting portion 3 protruding from the cover is integrally formed of a transparent body made of the same material, has a remarkably reduced diameter with respect to the cover 2, and projects finely in a tapered shape. 4 is bored and has a threaded portion 4a on its inner peripheral surface, and the threaded portion 5a provided on the pen shaft 5 of a ballpoint pen or the like is screwed onto the threaded portion 4a to mount and fix the pen shaft 5 of the pen mounting portion 3. To do. The object of the present invention is achieved by fixing the illustrated cover 2 and pen shaft 5 so as not to rotate or fall off. 6 is a cap.

[0007]

As described above, according to the present invention, the cover 2 made of a transparent material is detachably attached to the tip of the rod-shaped flashlight 1, that is, the side of the illumination light, and the tip of the cover 2 is integrated with the cover 2. Similarly, a pen mounting portion 3 of a transparent body is formed, and a shaft 5 of a writing instrument such as a ballpoint pen is inserted into an insertion hole 4 formed in the pen mounting portion 3.
According to the configuration in which the pen is detachably inserted and fixed, the light illumination of the electric lamp is illuminated in the pen tip direction through the cover 2 and the pen mounting portion 3, and writing can be performed easily and easily even in a dark place such as at night. It is possible to enjoy the function of a flashlight at the same time, and it is convenient to use. Especially, the pen attachment part 3 has a taper-like shape with a significantly reduced diameter compared to the cover 2. As seen from the experimental results, the light condensing action is obtained at the pen mounting portion 3, and the brightness is further increased in a range in which the pen tip portion is approximately equal to the contour of the pen mounting portion 3 as compared with the brightness around the pen tip. It is very useful for writing in strong and dark places.

Claims (2)

[Claims] 1. A rod-shaped flashlight 1 has a transparent cover 2 removably attached to the tip, that is, the side of the illumination light, and a pen mounting portion 3 of the transparent body integral with the cover 2 at the tip of the cover 2. The writing instrument with a light is characterized in that a shaft 5 of a writing instrument such as a ballpoint pen is detachably inserted and fixed into an insertion hole 4 formed in the pen attachment portion 3. 2. The pen mounting portion 6 of the cover 2 is the cover 2
A writing instrument with a light in which the pen attachment portion 3 is tapered and protrudes from the cover 2 with a significantly reduced diameter compared to the above.
