BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush pen which can be used with the same feeling as a calligraphy brush (hereinafter referred to as the present brush).

[0002]

[Prior Art] A brush made of bamboo or the like and attached with a tip made of a bundle of hairs attached to the tip of the axis is written with ink ink and ink ink added to the tip, but one character is written. Sometimes, the ink is written all at once without including it in the tip, so if the character is large, the ink in the tip will be reduced during writing, and the difference in shading between the beginning and the end of writing one character Often occurs, and "fading" often occurs. And this difference in shading and "blurring" is regarded as a unique taste of calligraphy.

[0003] However, using this brush requires time and labor for preparing ink, and requires many tools such as inkstones and inkstone boxes, so that it is expensive and not very suitable for carrying. For this reason, a brush pen has been put into practical use in which an ink cartridge is stored in a barrel, or ink is directly filled in the barrel, and ink is supplied to a tip attached to the tip of the barrel to write.

[0004]

[Problems to be Solved by the Invention] By the way, the brush pen has an advantage that it can be used easily, and is widely used for New Year's cards written at home. Since the ink inside is supplied sequentially to the tip, it can be written at a uniform density without a difference in shading or "shading", so that a flat character is obtained. That is, the brush pen cannot be used with the same feeling as the present brush. For this reason, not only in full-scale calligraphy, but also in calligraphy classes in elementary schools and calligraphy classes for children, the brush is used exclusively in spite of the inconveniences described above.

Accordingly, the present invention has an object to provide a brush pen that can be used in the same sense as a real brush for writing by adding ink to the tip of the brush, which can cause a difference in shading when the characters are large. I do.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a brush pen, in which ink in a barrel is supplied to a tip formed by bundling hairs and is written on, and the tip is attached to the tip. A small ink chamber is formed in the large tip, and a first valve and a second valve attached to a cylinder connected to the shaft cylinder and slidable in a liquid-tight manner with respect to the large tip, and a rod fixed to the large tip. When a valve mechanism is constituted by the valve and the shaft cylinder is advanced with respect to the forehead, the first valve separates from the advanced cylinder and the second valve comes into contact with the cylinder in a liquid-tight manner, and the ink at the tip is contained in the cylinder. When the ink equal to the possible amount is accumulated and the advance of the barrel is released, the first valve retreats and comes into liquid-tight contact with the cylinder restored to the original position, the second valve separates from the cylinder, and the ink in the cylinder is released. Filled in small ink chamber, only ink in small ink chamber Previously to be supplied.

[0007]

In other words, when the barrel is advanced with respect to the large tip, the valve mechanism opens and the small ink chamber is filled with ink equal to the amount of ink that can be contained in the tip, and only this ink is supplied to the tip. Performing the valve operation once has the same effect as adding ink to the tip of the brush, and ink is not constantly supplied to the tip as ink is consumed. Therefore, a difference in shading or "shading" is generated in the character, and the character can be used with the same feeling as the present brush.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the embodiments shown in the drawings. In FIG. 1, a tail plug is provided at the tail end of the barrel 1.
12 is fitted, and the inside of the barrel 1 is directly filled with ink having a relatively high viscosity. And, at the tip of the barrel 1,
The cylinder 4 is connected via a joint 11.

The tip 3 is similar to the tip used for a bold type brush and is fixed to the large tip 2. Great point 2
Is provided with a small air hole 21 that allows air and ink to be exchanged during writing and does not leak ink. A rod 7 is erected in the inner hole of the toe 2, and disc-shaped first and second valves 5 and 6 whose outer diameter is equal to the inner diameter of the cylinder 4 are attached to the upper end and lower part of the rod 7. And
The cylinder 4, the first valve 5, and the second valve 6 constitute a valve mechanism.

As shown in FIG. 2, an O-ring 22 fitted on the inner surface of the large tip 2 is in close contact with the outer peripheral surface of the cylinder 4 while the tip of the cylinder 4 is inserted into the large tip 2. Then, the cylinder 4 is repelled toward the tail end by the spring 8, and when the shaft cylinder 1 is pressed against the resilient force of the spring 8 and is advanced toward the forehead 2, the cylinder 4 is repelled to the forehead 2. On the other hand, when the shaft cylinder 1 moves forward in a liquid-tight state and the pressing is released, the shaft cylinder 1 retreats and returns to the state shown in FIG. When the cylinder 4 moves back and forth with respect to the tip 2, the first valve 5 or the second valve 6 is in a liquid-tight state and the cylinder 4
Move back and forth inside. Here, the space below the valve mechanism is the small ink chamber 9, and the capacity of the small ink chamber 9 is so small that the tip 3 can contain the ink in the small ink chamber 9 at a time.

When not in use, as shown in FIG.
Is in close contact with the inner peripheral surface of the cylinder 4 and the valve mechanism is closed, and the ink I does not exist in the cylinder 4 and in the small ink chamber 9. In writing, when the barrel 1 is advanced to the tip 2 side, as shown in FIG. 3, the first valve 5 comes out of the cylinder 4 and the second valve 6 comes out of the cylinder 4.
The ink I comes into the cylinder 4 in such a manner as to be in liquid-tight contact with the inner peripheral surface of the cylinder 4 and to be included in the tip 3 at a time. Next, when the advancing of the barrel 1 is released, the second valve 6 comes out of the cylinder 4 and the first valve 5 comes into liquid-tight contact with the inner peripheral surface of the cylinder 4, so that the ink I in the cylinder 4 becomes small ink chamber. Go inside 9. Then, the ink I in the small ink chamber 9 is supplied to the tip 3, and the amount of ink is such that the tip 3 can be included at one time, and the first valve 5 is connected to the inner peripheral surface of the cylinder 4. And the valve mechanism closes, and the ink I in the barrel 1 does not enter the small ink chamber 9, that is, the ink I is not supplied to the tip 3 any more. It will be in the same state as it was. Therefore, if a large character or the like is written in such a state, a difference in shading or "shading" occurs, and the character can be used with the same feeling as the present brush. When the ink I contained in the tip 3 is consumed, the valve opening operation is performed again to continue writing.

[0012]

As described above, in the brush pen of the present invention, a small ink chamber is formed in the large tip to which the tip is attached, and the valve mechanism is opened when the barrel is advanced with respect to the large tip. The small ink chamber is filled with ink equal to the amount of ink that can be contained in the tip and only the ink in the small ink chamber is supplied to the tip. There is a difference in shading and "blurring", and it can be used with the same feeling as this brush.
