Description of the invention (1) (Technical field to which the invention belongs) The present invention relates to a writing instrument capable of removing a marker pen, a ballpoint pen, and the like from a pen holder. (Previous technology) As the so-called singular pen center, plastic pen center, and ball core center, the pen center can be detached from the pen body, and it is known as Shiko Sho 51-14262 and Shiko Sho 52-2504. Shi Gong Zhao 5 2-4 6 1 7 5 and so on. These pens can be refilled or the ink can be refilled after the pen is removed. However, it may be damaged by directly holding the pen core, and it may become almost impossible to reuse the pen core. In this way, a writing instrument capable of being detached from the writing instrument body and holding the above-mentioned writing core holder is known, and it is known from Japanese Sho 6 2-5 3 5 3 and the like. These pens can be replaced without hurting the pen, or the ink can be replenished after removing the pen holder. However, the structure of the screw-in pen holder and the pen body is complicated, which is inconvenient. (Problems to be Solved by the Invention) The present invention has been made to overcome the above-mentioned problems, and to provide a writing instrument that can be detached from the body by an easy means and a method for detaching the writing instrument. (Means used to solve the problem) A writing instrument, which belongs to a writing instrument composed of a body and a cap for holding the center of a pen, is characterized in that an engaging portion is provided on the center of the pen, and -1 ^ --- --------- install --- (please read the precautions on the back to write this page). CNS) A4 specification (21 × 297 mm) -4- 504467 A7 B7 5. Description of the invention (2) The pen cap is provided with a protruding portion; and a method for detaching the pen holder, and engaging the protruding portion with the engaging portion , And detach from the pen holder. • I ^ ----------- Shang --- (Please read the phonetic on the back? Matters to write on this page) (Implementation of the invention) One side is shown in the implementation of Figures 1 to 3 The example details the writing instrument of the present invention. The 1-line refill holder is provided with an engaging portion 2 on the outer side, and the same outer side is provided with a locking portion 3 for preventing the refill holder from entering the body. The pen core 4 made of acrylic fiber is held inside the pen core holder. In this embodiment, since the engaging portion 2 and the engaging portion 3. protrude from all the outer periphery of the pen holder 1, the grooves are formed therebetween. The 5 series body holds the above-mentioned refill holder at the front end and contains an ink absorber made of polyester fiber. ; Line-6 series caps, cut out part of the cap shape, and provided with a protrusion 7 at the front end. In this embodiment, the thickness of the protruding portion 7 is set to the same thickness as the width of the groove formed by the engaging portion 2 and the locking portion 3. To refill the ink or replace the pen holder, firstly engage the printed portion 7 of the consumer cooperative of the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs on the engaging portion 2. The groove shape formed by engaging with the engaging portion 2 and the locking portion, \, pulls the pen cap 6 and the main body 5 in opposite directions. In this way, since the refill holder 1 is detached from the main body 5, the ink is replenished from the opening of the main body 5 as necessary. Especially in this embodiment, 'because the protrusion 7 is embedded in the groove-shaped state formed by the engaging portion 2 and the engaging portion 3, the pen core-protection-5- This paper size applies Chinese National Standard ) A4 specification (210 X 297 mm) 504467 A7 B7 V. Description of the invention (3) After the holder 1 is removed from the main body 5, it will also remain engaged, and there will be no pen holder during the refilling period. It is difficult to place and does not stain the pen holder and fingers. After that, the pen cap 6 is held, and the pen holder 1 is inserted into the main body 5 to return to a state in which rewriting is possible. In this embodiment, the tail plug 9 is held on the body 5 via the pad 10. A recess 8 is provided at the end of the tail plug 9. To remove the tail plug, insert the protruding portion 7 of the cap 6 into the recessed portion 8 and twist both. In this way, since one part of the protruding portion 7 functions as a fulcrum and the other part pushes the tail bolt upward, the body 5 can be easily separated from the tail bolt 9. The protruding portion 7 of the pen cap is inserted into the recessed portion 8, and both can be pulled out of the tail bolt 9 from the main body 5. Thereafter, the ink absorber contained in the main body 5 can be detached and can be easily handled separately. If necessary, ink can be replenished from the opening at the rear end of the main body 5. In the present invention, since the protruding portion 7 is formed in the cap, there is no need to specially prepare a screwdriver or the like, and the user can simply handle each separately. The caps and refill holders of the other embodiments are shown in Figs. 4 and 10, but the present invention is of course not restricted to this embodiment. The cap of the second embodiment shown in Fig. 4 and Fig. 5 is formed by cutting out a part of the shape of the cap, and forming two protruding portions ′ which are grooved between the two. The cap of the third embodiment shown in Figs. 6 and 7 is formed by forming a collar-shaped projection on the front end portion of the cap. The refill holder of the fourth embodiment shown in FIG. 8 is provided with an engaging portion on the outer side of the front end of the refill holder, in order to integrate the engaging portion with a smaller protruding distance than the engaging portion with the engaging portion For local installations, those with stage-like shapes, the paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) (please read the note on the back first to write this page).

To detach the pen holder from the main body, hook the protruding part to the engaging part, and pull the pen cap and the main body in opposite directions. In this way, you can get rid of both. The refill holder of the fifth embodiment shown in FIG. 9 and FIG. 10 is provided with a notch 11 in a part of the locking portion in addition to the integrated engaging portion and the locking portion. To release the pen holder from the body, insert the protruding part into the notch 11 and hook it on the engaging part, and pull the pen cap and the body in the opposite direction. In this way, you can get rid of both. In the present invention, any combination of the caps and refill holders of all the embodiments may be used, and any shape other than these that can obtain the same effect can also be used. (Effects of the Invention) The present invention is capable of detaching the pen holder from the main body using easy structure and means, and can replace the pen holder and refill ink.
