Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument having a pen body capable of guiding and retaining ink supplied from a writing instrument body, and more particularly to a paint marker, an oil-based marker, an aqueous marker, and an underline. The present invention relates to a type of liquid writing implement called a pen.

[0002]

2. Description of the Related Art Conventionally, as a form of a liquid writing implement for supplying ink from a writing implement main body to a pen body serving as a pen tip, for example, ink is held in an ink occluding body connected to a rear end of the pen tip. Writing implement, a writing implement that provides a valve mechanism between the pen tip and the ink chamber and releases the valve by pressing and moving the pen tip to draw out ink, a writing implement that knocks on the rear end to release the valve mechanism, A plug and a valve body that advance liquid-tightly in the ink chamber are provided, and a small number of writing elements are released by the negative pressure that accompanies the writing to supply ink. Various liquid writing tools, such as a writing tool provided with an ink reservoir (collector member) having a fin, are known.

[0003] However, in these liquid writing instruments and the like, when writing with a wide drawing line width from left to right using the right hand, it is difficult to see the right side of the pen body because the pen body as the pen tip is thick and the right side of the line is difficult to see. It is inconvenient when trying to specify the end point position. This is remarkable when a frame of a table is drawn on imitation paper or the like, or when characters are painted on a horizontally written material with an underline pen or the like. In order to eliminate this inconvenience, right-to-left handwriting or as shown in FIG.
There are cases in which the writing implement is handled in an unnatural manner, but these are different from the original way of using the writing implement, giving a sense of incongruity and putting an unreasonable burden on the fingers and the like.
FIG. 27 (b) is a handwriting in a natural holding style.

[0004] An inconvenience problem or the like that occurs when trying to specify the right end point position of a line is that the drawing line width of the writing portion is 2 m.
This is more likely to occur with writing instruments as thick as m or more.
In addition, when writing at a writing angle of 45 degrees or less, the above-described problem is unlikely to occur, but writing at a low writing angle is very inconvenient for writing near a body. Use in a relatively narrow place such as an airplane further causes the above-mentioned inconvenience. This is not only the shape of the writing portion of the pen body, but also the writing implement 3 in which the pen tip portion 1 and the shaft portion 2 are bent as shown in FIG. 28 (for example, Japanese Utility Model Application Laid-Open No. 56-140485). However, if the writing angle is large, the opposite side of the pen becomes invisible, and if the writing angle is small, the opposite side is visible depending on the structure, but there is inconvenience in writing near the body, and there is the same problem as described above. In addition, brush pen and actual opening Sho 5
In a writing instrument having a variable thickness and a flexible pen tip described in Japanese Patent Application Laid-Open No. 4-33731, if a writing load is applied to some extent, the opposite side of the pen is visible, but a stable writing line width cannot be obtained. There are inconvenient issues.

Further, some writing instruments having a split nib having an ink guide slit such as a fountain pen include, for example, Japanese Utility Model Laid-Open No. 48-51427 and Japanese Utility Model Laid-Open No. 49-11502.
No. 3, JP-A-3-29390, JP-A-9-5
There are many known ones having a bent pen tip as disclosed in Japanese Patent No. 2486. However, the main purpose of these writing instruments is to make the drawing line width variable like the above-mentioned brush pen, and in the case of a writing instrument of the "U-shaped" type, the pen tip portion 1 shown in FIG. In addition, there is a problem similar to that of the writing implement 3 in which the shaft 2 is bent, and the nib of the split pen is not only suitable for writing in the pen tip direction but also in the horizontal direction. Not something.

[0006]
