Description

  The present invention relates to a writing instrument such as a marker pen, a felt pen, a sign pen, or a ballpoint pen, and more particularly to a writing instrument including a magnet that can be adsorbed to a wall surface made of a magnetic material such as a wall surface of a steel desk or a refrigerator when not in use.

  As such a writing instrument, conventionally, as described in, for example, Patent Document 1 and Patent Document 2, a writing instrument in which a magnet is fixed to a main body shaft portion is known. That is, in Patent Document 1, a writing instrument in which a plate-like magnet is fixed to an appropriate position on the outer peripheral surface of the main body shaft portion such as a ballpoint pen or a mechanical pencil with an adhesive, or a ring-shaped magnet is fitted on the outer peripheral surface of the main body shaft portion. Similarly, Patent Document 2 describes a writing instrument such as a mechanical pencil or pencil in which a plate-like magnet is attached to the outer peripheral surface at the tip portion of the shaft portion.

Utility Model Registration No. 3137267 Japanese Utility Model Publication No. 7-33694

  However, in a writing instrument in which a plate-like magnet is fixed to an appropriate position on the outer peripheral surface of the main body shaft portion as described above, the magnet is attracted to a wall surface made of a magnetic material such as a steel desk so that it rolls off from the desk. The writing instrument can be fixed by preventing the magnet from adhering to a panel surface made of a magnetic material such as a refrigerator, but such a writing instrument has the same magnetic pole, for example, N magnetic pole surface on the surface side. Since the magnet is fixed to the outer peripheral surface of the main body shaft part in the facing direction, even when trying to align the two writing instruments, the magnets are repelled and stored in a pen box or pen tray. In addition to being difficult to keep, writing tools may be separated and lost.

  On the other hand, in a writing instrument in which a ring-shaped magnet is fitted to the outer peripheral surface of the main body shaft, two writing instruments are provided by setting one semicircular part as an N pole and the other semicircular part as an S pole. Although the magnets can be joined together in an aligned state, since the magnet is integrally fixed to the main body shaft, the other writing instrument is directed to one writing instrument so that different magnetic poles of the magnets face each other. In addition, even when trying to focus a plurality of writing tools, the writing tools that adsorb each other's magnets and the writing tools that repel each other are generated in the adjacent writing tools, and are attracted to the focused state. However, even if multiple writing instruments cannot be held and stored in a brush case for sale or storage, they will be repelled and cannot be stored cleanly. there were.

  Also, even when drawing multicolored color letters and illustrations using multiple writing instruments of different colors, it is difficult to place the writing instruments other than the writing instrument being used in one place. Therefore, there was a problem that it took time to create illustrations.

  The present invention has been made in view of such problems, and the object of the present invention is to bring the writing instrument closer to the panel surface without directing the magnetic pole of the magnet provided on the writing instrument to the panel surface made of a magnetic material. The writing tool can be easily attracted to the panel surface by the magnet, and not only can the writing tools be instantly attracted and held in the aligned state by simply bringing them close to each other, but also a plurality of them can be converged. It can be absorbed and held in a state to eliminate the possibility of losing it, and it can be easily stored, etc., and it can easily be used to write a desired color from multiple writing tools of different colors even in use. It is in providing a writing instrument provided with a magnet that can be taken out.

It is formed in the S pole.

  According to the first aspect of the present invention, the magnet storage chamber is provided in the shaft cylinder of the writing instrument, and the magnet is housed in the magnet storage chamber so as to be movable in the axial direction and the circumferential direction of the shaft cylinder. When a writing instrument is brought close to a panel surface made of a magnetic material such as a steel desk or a refrigerator, the magnet in the magnet storage room moves freely in the magnet storage room so that one of the magnetic poles faces the panel surface. It can be reliably adsorbed to the panel surface regardless of the orientation of the and the writing instrument can be easily fixed and held on the desired portion of the panel surface. Similarly, when the writing tools are to be aligned with each other, the magnets provided in these writing tools are automatically actuated so that different magnetic poles face each other in the magnet storage chamber, and are immediately attracted and held in the aligned state. be able to.

  Furthermore, when three or more writing tools are bundled, the magnets in the magnet storage chambers of adjacent writing tools can be attracted by changing their magnetic pole face instantly so that they attract each other. Can be kept in a state. Therefore, not only can it be lost, but it can be stored and stored neatly in a pen box or pen dish, and it is also desirable when using multiple writing instruments of different colors.
