[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument with a finger guide, and more particularly to a writing instrument with a finger guide that allows a user to put the writing instrument on his / her finger so that he / she can write immediately while using without having to remove it from his / her hand during work.

[0002]

2. Description of the Related Art The inventor of the present application has proposed Japanese Patent No. 2786830 as such a writing instrument with a finger guide. This is composed of a ring portion positioned between the first joint and the second joint when the index finger is inserted, a guide portion extending from the ring portion along the index finger, and a writing portion protruding from the tip of the guide portion. In this case, the ring portion is a writing instrument with a ring extending obliquely rearward and upward with respect to the guide portion. Also,
In addition to the above writing instrument, there is a portable writing instrument 20 shown in FIG.

[0003]

However, the conventional Japanese Patent No. 2786830 has the following problems. First, when the writing instrument is not in use, the writing instrument is inserted facing up, and when it is used, the writing instrument is inserted downwards.Therefore, remove the writing instrument with the other hand before and after use. I had to change direction. For this reason, it is inconvenient because the work must be interrupted each time the other hand is used for other work.

Also, by inserting the index finger into the ring part,
When the tip of the writing part is sandwiched between the thumb and middle finger, the second joint part of the index finger bends in the ring part, so the shape of the index finger does not fit and the second joint part of the index finger is pressed during writing, making it difficult to write. .

Further, since the core portion is attached so as to project straight from the guide portion, the core portion should be positioned at a right angle to the writing surface unless the index finger is placed at a right angle to the writing surface.
There is a problem in that it is difficult to write because the posture for holding the writing instrument is unreasonable because the angle does not reach approximately 0 °.

In addition, the writing instrument 20 shown in FIG. 11 has a problem that it must be held each time it is used, and it is easily lost. Moreover, since the writing instrument 20 itself is slender and the space for inserting advertisements is small, the advertising effect is small.
