Abstract
This drafting pen has an improved internal structure in which a plurality of air holes perforate the upper periphery of a sub shaft, a cover with a knob provided at a distance from the holes and a lower wavy end engages with the vicinity of the base of a needle with a weight, so that ink and air can mix and the phenomenon of ink accumulating at a narrow gap so as to leak externally hardly occurs. The air advances through the space into an inserted shaft so that the ink can conventiently flow out. In a pause in use, the ink in the shaft is extracted into its reservoir under guidance. Then a core rod in the reservoir is isolated together with the reservoir when the pen is in use, thereby adjustably opening or closing a communicating hole in the main shaft passing the ink to prevent excess flow due to air pressure. A rotary flexible sub cap engages within the cap to seal the pen hermetically. In this manner, even if the pen is shaken to any extent during use, no ink leaks between the main shaft and the sub shaft, as it would in a conventional pen, thereby eliminating irregular ink flow due to defects of the air, and obviating contamination of the fingers and the drawing due to droplets of ink.

The flow was smooth and the drawing efficiency was improved. Different from the past]? In the air shaft delivery, drill a plurality of holes in the upper part of the counter shaft, insert a hole in the hole, pick it up, insert a force par with 10 and make the lower end wavy, and fit it to the needle base Therefore, air infiltrates through a narrow gap. Ink, on the other hand, made it difficult to leak back, and the air was not obstructed by the ink.過 剰 Ink tank pressure rods are used to control the excess pressure received by the ink tank, and the tank ink is finished! ? Enabled up to now. Furthermore, when the machine is not in use, the auxiliary shaft and the tank ink can be separated and placed. However, in the conventional method, the ink leaks into the air channel and hinders the inflow of air, resulting in malfunction.In addition, the tank has an excessive outflow due to the pressure change due to temperature change. Another drawback was that there were many disasters caused by the 'suspended ink'.

The narrow gap 7 between the counter shaft 2 and the force par 3 enters the air shaft. Conversely, the ink in the shaft spills upward, but in a narrow gap, the ink causes a dripping phenomenon, making leakage extremely difficult. At 玆, the air lurks through this gap 7]. The air and the ink that enter the air constantly intersect with each other, but the air pressure from above causes the junk to be pushed into the shaft. With this operation, there is no fear that the ink will dry and stick. Therefore, there is no leakage of ink between the main shaft and the counter shaft. Next, a protrusion 9 is provided in the cap 8 so that the flexible sub-cap 10 can be completely closed without rubbing the tip of the tip. Ink tank 1 1 Attach core rod 1 2 in the center, and use the tip to contact the main shaft 1 and the communication hole 5 of the cover 3]. Tank 1 1 is the main shaft 1]. When the tank is at rest, the tank is pulled out of the shaft 11 at the time of suspension.The ink in the shaft is guided to the tank 11 and can be removed. In addition, it is possible to close the shaft 1 and 2 at the contact hole 5 and to close the shaft and the tank. .
新く してエアー と イ ンク と の相互関係が調和され快調 に使用できる特長と効杲がある。 The new relationship between the air and the ink is harmonized, and there are features and effects that can be used smoothly.
