Furthermore, in addition to the above embodiments, for example, by mixing gold powder (foil) and silver powder (foil), it is possible to compose a edging effect ink whose color tone can be arbitrarily changed and adjusted.

Although not shown in the drawings, a cap for covering the pen tip 21 is attached to the pen holder 16.

When the apparatus constructed in this manner is used, when the main body 1 is shaken several times, the ball 4 moves up and down, and the edging effect ink 3 is well stirred by the ball 4. Next, when the cap is removed and the writing part 21a at the tip of the pen nib 21 is pressed, the pen nib 21 is moved forward and backward against the coil spring 15, and the valve rod 12 is moved forward and backward by the nib 21, and the valve 13 is opened. The through hole 9 is opened and closed apart from the seat 10.

When the through hole 9 is opened, the edging effect ink 3 stored in the ink storage section 2 of the main body 1 is released.
The ink flows into the pen holder 16 through the through hole 9, is stored in a predetermined amount in the ink reservoir 19, and is impregnated into the pen nib 21.
(Porous fiber bundle) The writing part 2 is
It is induced and impregnated up to 1a and becomes ready for writing. Also, when the pressure on the pen tip 21 is released, the coil spring 1
5, the valve rod 12 is pushed out and the valve 13 is moved to the valve seat 10.
The nib 21 is pressed in a liquid-tight manner and the rear end thereof is locked by the locking seat 14 of the valve rod 12, and the pen tip 21 is pushed out.

In this state, the writing part 21a of the pen tip 21
When a desired character 26 is written on a subject having liquid permeability, that is, a predetermined paper sheet 25, the colored dye in the edging effect ink 3, that is, the liquid colored ink 27 penetrates and diffuses into the paper sheet 25. Because of its properties, it penetrates into the paper sheet 25 and diffuses to a predetermined width, that is, in a wider area than the thickness of the writing part 21a of the pen tip 21. The insoluble colored fine particles 28 do not penetrate and diffuse into the paper sheet 25, so they separate from the colored ink 27 on the paper sheet 25, do not permeate and diffuse into the paper sheet 25, and do not penetrate into the pen tip 2.
It is fixed on the upper surface of the paper sheet 25 with a size similar to the thickness of the writing part 21a of No. 1, and therefore, insoluble colored fine particles such as gold powder, silver powder, etc. are deposited on the paper sheet 25 with one writing. A character 29 consisting of 28 and a multicolored handwriting with a border 30 of a predetermined width formed around the character 29 by permeation and diffusion of liquid colored ink 27 are simultaneously expressed.

In the embodiment described above, a case has been described in which a pen nib 21 made of a porous fiber bundle or the like like a felt pen is used, but the pen nib 21 is not limited to this, and may be something like a brush. Further, although a marker such as a so-called felt-tip pen is used as an example of the writing instrument, the present invention is not limited to this, and may be a fountain pen or other writing instrument.

According to the present invention, a colored dye that permeates and diffuses into the paper sheet and an insoluble colored fine particulate material that does not permeate and diffuse into the paper sheet are mixed in an ink storage part formed in a main body having a pen tip. By storing a edging effect ink composed of
The insoluble colored fine particles separated from the colored dye are firmly fixed on the surface of the paper sheet, and the colored dye that has permeated and diffused into the paper sheet in a predetermined width develops color around the insoluble colored fine particles. Since the colored dye and the insoluble colored particulate matter are colored in different colors, it is possible to automatically produce colorful handwriting with an excellent visual effect, which gives the appearance of a border in one handwriting.

In addition, by selectively using gold powder, silver powder, etc. as insoluble colored fine particles, for example,
It is possible to create the most suitable handwriting for each purpose, such as for signatures and for congratulations and condolences.

Furthermore, by storing the ball in the ink storage portion of the main body, the edging effect ink can be stirred and mixed, and precipitation separation of insoluble colored fine particles can be eliminated.
