By twisting the cap 18 with respect to the front shaft cap 20, the rear end 18 b of the cap 18 slides against the stepped surface 20 c of the front shaft 20, and a force is generated in a direction in which the cap 18 moves away from the front shaft cap 20. They leave. As shown in FIG. 2, when the cap 18 is removed, the pen tip 10a of the first pen body 10 is exposed.
The rear end portion 20b of the front shaft cap 20 is detachably fitted to the outer periphery of the entire front shaft 22.

[Lead shaft 22, valve structure 24]
As shown in FIG. 3, the front shaft 22 has a substantially tubular structure in which a tip end portion 22a, a center portion 22b, and a rear end portion 22c are increased in diameter in order, and the second pen body 12 is provided at the tip end portion 22a. It is installed so that it can protrude and retreat. In the central portion 22b, there is an ink retaining body 26 that can be impregnated with ink, and the valve structure 24 is disposed in the rear end portion 22c.

  As shown in FIGS. 2 and 3, the valve structure 24 includes a valve seat 24a that communicates with the front and rear openings, a valve body 24b that moves forward and backward with respect to the valve seat 24a, and a valve body 24b that opens and closes. And a spring 24c for urging the spring 24c.

  The valve body 24b is in contact with the rear end portion of the second pen body 12 at the tip, and when the second pen body 12 moves rearward, the valve seat 24a is opened, and the inside of the valve seat 24a is opened. The ink is distributed and supplied to the second pen body 12.

[Ink storage section 16]
The ink storage unit 16 has a structure in which ink is stored in a space inside the shaft tube 14, and a stirring ball 28 is provided in the space to prevent ink from settling. The ink containing the component which precipitates, such as a pigment, can be sufficiently stirred.

[Operation of marking pen]
In the marking pen of the present embodiment, before the first pen body 10 is used, as shown in FIG. 1, the cap 18 is put on the front shaft cap 20, and the pen tip of the first pen body 10 is used. 10a is not exposed. The first pen body 10 is in contact with the second pen body 12 so that ink flows.

  Then, when the first pen body 10 is used, the cap 18 is twisted and removed from the front shaft cap 20 to expose the pen tip 10a of the first pen body 10 as shown in FIG.

  In this case, the plurality of pen bodies 10 and 12 are in direct contact with each other, specifically, the rear end of the first pen body 10 is in contact with the front end of the second pen body 12, and ink flows. Yes. In order to circulate ink, the first pen body 10 is pressed against a contact surface such as a paper surface, the first pen body 10 is moved backward, and the valve body of the valve mechanism 24 is passed through the second pen body 12. 24b moves backward with respect to the valve seat 24a to open the valve. The ink is impregnated and guided from the second pen body 12 at the tip of the valve body 24a to the first pen core 10 so that writing or application can be performed from the pen tip 10a.

  With the above configuration, the ink in the ink storage unit 16 is connected to the first pen body 10 through the second pen body 12 so as to be conductive, so that the ink can be sufficiently conducted to the first pen body 10. It can be. Therefore, both the pen tip 10a of the pen body 10 and the pen tip 12a of the pen body 12 are difficult to dry.

  Further, by pulling the front shaft cap 20 away from the shaft tube 14 in the axial direction, the front shaft cap 20 is separated from the front shaft 22 and removed as shown in FIG. Since the front shaft 22 is screwed to the shaft tube 14, it is in a fixed state.

  In order to distribute ink, the second pen body 12 is pressed against a contact surface such as a paper surface to retract the first pen body 12, and the valve body 24b of the valve mechanism 24 is retracted with respect to the valve seat 24a. To open the valve. The ink is impregnated and guided into the second pen body 12 at the tip of the valve body 24a, so that writing or application can be performed from the pen tip 10a.

  In the embodiment, for one first pen body 10 among the plurality of pen bodies (first pen body 10, second pen body 12), the cap 18 is rotated in the rotational direction with respect to the shaft tube 14. The pen tip 10a is opened by twisting, and the pen tip 10a is opened by twisting the cap 18 in the rotational direction with respect to the shaft tube 14, and the other one of the plurality of pen bodies is separated from the shaft tube 14. Since the pen tip 12a is opened by being pulled away in the axial direction, the removal direction is changed. Therefore, the pen tips 10a and 12a can be easily selected and the mistake of removal can be eliminated.

  In the above embodiment, the first pen body 10, the second pen body 2, and the two pen bodies are raised as a plurality of pen bodies. However, this is an example, and three or more pen bodies are provided. May be. Also, the capillary force of each pen body may be made different so that the difference can be easily understood during writing. Further, by setting the capillary force of the pen body close to the ink storage unit higher than the capillary force of the pen body far from the ink storage unit, the ink supply of the pen body far from the ink storage unit can be stabilized.

  Further, as a structure in which a plurality of pen bodies are opened in different directions, the cap 18 is attached to one first pen body 10 among the pen bodies (first pen body 10 and second pen body 12). The pen tip 10a is opened by twisting in the rotation direction with respect to the shaft tube 14, and the front shaft cap 20 is connected to the shaft tube 14 with respect to the other second pen body 12 among the pen bodies. This is realized as a structure in which the pen tip 12a is opened by pulling it apart in the axial direction.

  Of course, this structure is only an example, and the twisting structure and the pulling structure may be reversed. Further, both of them have a structure that opens when twisted, and a structure that opens when twisted in the opposite rotation direction, or a structure that pulls both, and the friction coefficient between the cap 18 and the front shaft cap 20 and the front shaft cap 20. Also, the friction coefficient between the front shafts 26 may be different.

  The marking pen of the present invention can be used in various ways other than writing and application, as well as cosmetic application.
