Abstract

PROBLEM TO BE SOLVED: To make the expression of the form of a character plentiful by making it possible to write, for example, a character different in thickness and density by one ball-point pen. SOLUTION: The ball-point pen has two pen points 3a and 3b, and the ink guide holes 5a and 5b from an ink tank 1 communicate with the balls 4a and 4b provided to the leading ends of the pen points and the writing conditions of the balls 4a and 4b of the pen points 3a and 3b are made different.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ballpoint pen.

[0002]

2. Description of the Related Art A conventional ball-point pen has only one pen tip at a pen tip portion. For example, even if a character having a different thickness is to be written, it cannot be written with one pen. Therefore, there was a limit in the expression of the font.

[0003]

An attempt is made to enrich the expression of characters by allowing a single ballpoint pen to write, for example, characters having different thicknesses and densities.

[0004]

1 to 4 show an embodiment in which pen tips 3a and 3b are provided in a crossing direction, and FIGS. 5 to 8 show a case in which pen tips 3a and 3b are provided in a parallel direction. . 1 to 8, 1: ballpoint pen 2: pen tip 3a: first pen tip 3b: second pen tip 4a: first ball 4b: second ball 5a, 5b: ink conduction hole 6: refill
7: Knock

[0005] In the embodiment of Figs.
As shown in 2 and 3, the ballpoint pen 1 is turned over and the pen tip 3
a, 3b can be used. In the embodiment of FIGS. 5 to 8, the ballpoint pen 1 is tilted in the opposite direction as shown in FIGS. 7 and 8, and the first and second nibs 3a and 3b are used. In the embodiment shown in FIGS. 5 to 8, as shown in FIG. 9, the refill 6 may be pressed by the knock 7 so that the pen tip is made to protrude and retract from the pen. The ink conduction holes 5a and 5b from the ink tank are communicated with the balls 4a and 4b. And the first,
If the diameters of the balls 4a and 4b of the second pen tips 3a and 3b and the sizes of the pen tips 3a and 3b are changed, the writing style of the pen tips 3a and 3b can be changed, and a rich writing feeling can be obtained. Can be given. In this way, for example, if the first pen tip 3a is made thick and dark, and the second pen tip 3b is made thin and thin, it can be used properly according to each purpose.

According to the present invention, two or more pen tips 3a,
3b, for example, fonts of different thicknesses can be written with a single pen, and writing with rich expression is possible.
