2. Description of the Related Art In general, characteristics of writing tool having a plate-shaped pen tip having a slit at the tip, the Oite during its writing, other
Unique to the writing instrument of
That is to have a writing quality. However, in a writing instrument provided with a pen tip having a writing tip such that one surface is for bold type and the other surface is for fine type (hereinafter, referred to as double-sided writing nib), the pen point hardly bends. Even if the pen tip has such a shape or can be bent, in order to fix the pen tip to the pen core, the front and back surfaces of the pen tip and the tip of the pen core and the pen pushing piece etc. Pinch with and fix
Because, nib Ru structure its entirety in almost not intonation. That
Therefore, in such writing instruments,
No taste was obtained, and it was not a so-called fountain pen-like writing feeling, but a ballpoint pen-like writing feeling.

[0003]

The problem of suppressing the pen tip itself can be solved by considering the shape, plate thickness and fixing method of the pen tip, but when the pen tip bends, the tip of the pen tip opens. However, since the amount of ink that migrates from the tip of the pen tip to the paper surface increases, there is a problem in that handwriting may be blurred if the amount of ink supplied to the slit portion of the pen tip is insufficient. Also, when using a pen tip for fine print, the handwriting width must be narrow, but when writing with the same writing pressure as the pen tip for bold print, the pen tip will be the same as for the bold print tip. There is a problem that the tip of the pen tip is bent and the handwriting width becomes thicker. Alternatively,
In order to reduce the handwriting width, it is necessary to make the writing pressure weaker than the writing pressure of the pen tip for bold characters, and changing the writing pressure according to the pen tip causes a problem in practical use.

The present invention provides a writing instrument having a double-sided writing nib, which has a structure in which the nib can be suppressed, and in order to solve the above problems, the writing nib is bent by the writing pressure of the writer. It has an ink outflow structure that allows the ink to follow the tip of the pen tip securely and sufficiently, and even if the pen tips for bold type and thin type are used with the same writing pressure, use the pen tip for fine type. In such a case, it is to obtain a writing instrument including a pen body having a structure in which the amount of bending is restricted as compared with a bold nib.

DISCLOSURE OF THE INVENTION The present invention provides a writing instrument having a double-sided writing nib, in order to obtain the above-mentioned writing instrument, one side of the writing tip is for bold type and the other side is for writing type. And an elastic plate-shaped nib having a slit at the center of the tip, and an elastic plate-shaped first nib support piece for supporting the nib in the front part and the first nib. A second nib support piece which is thicker and thicker than the support piece, and has a housing member having an opening at the rear end for housing the ink guide core at the rear part thereof. between the first nib support piece and the second pen tip support piece, and the bold for side to the second pen tip supporting one side of the writing tip end for fine print on the first nib support side, at least a The tip of the first nib support piece is attached so that it is positioned in the slit portion of the nib, and the tip is connected to the nib inside the storage member. Insert the click induction core, with the pen tip and the first pen tip support piece and by and nib and the second nib support piece,
Insert the pen body with the ink passage from the tip of the ink guide core to the slit of the pen tip into the ink guide core at the tip of the barrel.
The writing instrument is so mounted that its rear end is in contact with the ink contained in the barrel .

The nib and the nib support may be made of the same material or different materials. 1 nib support
It may be formed of one member, or may be formed of two or more members.

[0007]

Since the writing instrument of the present invention is constructed as described above, the pen tip is easily depressed by the writing pressure of the writer.

Even if the nib is bent, the first nib support piece or the second nib support piece is also bent, so that the nib and the first nib support piece, or the nib and the second nib. The ink passage formed by the nib support piece from the ink guide core to the slit portion of the nib is not cut.

Since the thickness and length of the support piece are different between the first nib support piece and the second nib support piece, even if a thick nib or a thin nib is used with the same writing pressure, In the case of small letters, it does not bend so much and the writing tip opens only slightly, so the handwriting width does not become thick.

[0016]

Since the writing instrument having the double-sided writing nib of the present invention is constructed as described above, the writing nib is suppressed by the writing pressure of the writer during writing, which is unprecedented. It has a good writing feel. The bending of the pen tip opens the tip of the writing, increasing the width of the handwriting,
Ink consumption from the slit portion of the nib is increased, but the pen tip and the first pen tip support pieces, or by a pen tip and an ink passage formed by the second pen tip support pieces, sufficient Ink can be supplied to the slit of the pen tip. Moreover, since the first nib support piece or the second nib support piece also flexes with the bending of the nib, the first nib support piece and the second nib support piece of the nib surface are bent from the surface of the nib. Since they are not separated from each other and the ink passage is not cut off, the ink can always be stably supplied. Therefore,
Handwriting defects due to ink fading do not occur.

First for the nibs on the side for bold type and the side for fine type
The pen tip support piece and the second pen tip support piece have different lengths and plate thicknesses to change the amount of bending of each pen tip support piece under the same writing pressure. It is hard to bend. Therefore, when writing with a pen tip on the side for fine characters, the writing tip does not open more than necessary and the handwriting width does not become thick.

Since the structure of the pen body is the same as described above, it can be easily assembled.
