In addition, since the engagement convex part 6a (refer FIG. 2 (a)) engaged with the square groove 12a formed in the peripheral surface of the attaching part 12 is provided in the inner peripheral surface of the fixing member 6, it intends. The fixing member 6 does not come off the pen tip 3 unless it is removed.

  FIG. 2D shows a state in which two weight parts 5 are attached, and the weight of the tip of the pen body 1 when the pen is rotated can be adjusted by the number of weight parts 5.

  The cap body 2 can be removed from the pen body 1 and can be fitted to the rotation operation member 4 disposed at the rear end of the pen body 1. A weight part 15 is provided inside the weight body 16. It is held in and accommodated. The weight part 15 has the same material and the same shape as the weight part 5 attached to the nib 3 described above. A guide groove 17 is formed in the longitudinal direction on the upper surface of the cap body 2, a first engagement groove 18 is formed on the front end side of the guide groove 17, and a number of second engagement grooves are formed on the rear end side. 19 is formed (see FIG. 3A).

  The weight part 15 can be moved in the cap body 2 while being held by the weight holding body 16, and the weight holding body 16 is shown in FIGS. 3 (a) and 3 (b). Further, a cylindrical attachment portion 21 for attaching the weight part 15 to the front surface of a circular base member 20 having a size substantially the same as the inner diameter of the cap body 2 is formed so as to protrude, and the rear surface is curved in a U shape to be a spring. A portion 22 is formed, and an operation button 23 is formed at the tip of the spring portion 22.

  Engagement protrusions 24 are formed on both side surfaces of the operation button 23 so as to protrude from each other, and the engagement protrusions 24 are formed in the guide groove 17 in the state of being accommodated in the cap body 2. It engages with either the groove 18 or the second engagement groove 19 and is fixed inside the cap body 2.

  In addition, the circumferential surface of the attachment part 21 is formed in a square wave shape as a whole with a square groove 21a provided at a predetermined interval.

  When the weight holding body 16 is housed from the front surface of the cap body 2, as shown in FIG. 4A, the engagement protrusion 24 engages with the engagement groove 18, and the attachment portion 21 is formed on the cap body 2. It is fixed in a state of protruding forward. In this state, when the weight part 15 is fitted into the mounting portion 21 and finally the fixing member 25 is fitted, as shown in FIG. 4 (b), the weight member 15 fitted into the mounting portion 21 is not detached. 25 can be fixed. In addition, since the engagement convex part 25a (refer FIG. 4 (a)) engaged with the square groove 21a formed in the peripheral surface of the attaching part 21 is provided in the inner peripheral surface of the fixing member 25, it intends. Unless fixedly removed, the fixing member 25 does not come off from the attachment portion 21 (weight holder 16).

  When the weight holding body 16 to which the weight part 15 is attached depresses the operation button 23 against the spring portion 22, the engagement between the engagement protrusion 24 and the first engagement groove 18 is released. If the weight holding body 16 is moved while being pressed, the weight holding body 16 can be slid rearwardly within the cap body 2, and if the operation button 23 is released, the spring portion 22 is urged and operated. Since the button 23 is raised and the engagement protrusion 24 is engaged with the second engagement groove 19 at the corresponding position, the weight holding body 16 is fixed in the cap body 2.

  The balance of the entire writing instrument when the pen is rotated can be adjusted depending on where the weight holding body 16 is fixed in the second engagement groove 19.

  Next, the usage aspect of the writing instrument A for pen rotation of the said structure is demonstrated. First, as shown in FIG. 2C, the weight part 5 is fitted into the pen tip 3, and the weight part 5 is fixed to the pen tip 3 with the fixing member 6 so that the weight part 5 is not detached. Next, as shown in FIG. 4B, the weight holding body 16 is moved to the front portion of the cap body 2 to protrude the attachment portion 21, and the weight part 15 is fitted into the protruded attachment portion 21. After fixing the fixing member 25 so that 15 does not come off, the operation button 23 is pressed to move the weight holding body 16 to the rear of the cap body 2.

  When the weight part 5 is attached to the pen body 1 and the weight part 15 is attached to the cap body 2 as described above, the cap body 2 is fitted to the tip of the pen body 1 in the same manner as a normal writing instrument. Set to the state of (a). When using this pen-rotating writing instrument A as a writing instrument, as shown in FIG. 1 (b), the cap body 2 is removed and fitted to the turning operation member 4 provided at the rear end of the pen body 1, and the cap The body 2 is attached to the rear end of the pen body 1 (see FIG. 1C).

  In this state, since the refill 8 protrudes from the pen tip, the grip portion 7 can be picked and used as it is as a writing instrument.

  When the pen is rotated using the writing instrument A in the writing instrument state, the pen body 1 can be held as it is with two fingers as shown in FIG.

  In this case, since the refill 8 protrudes from the pen tip 3, if the cap body 2 fitted to the rotation operation member 4 is rotated, the refill 8 is inserted into the pen by a known rotation knock mechanism (not shown). Since the inside of the tip 3 can be immersed, the trouble that the refill 8 hits a finger at the time of rotation and feels painful can be avoided.

  As described above, according to the writing instrument for pen rotation of the present invention, an arbitrary number of weight parts 5 are attached to the tip of the pen body 1, and an arbitrary number of weight parts 15 are attached to the weight holding body 16 built in the cap body 2. If the operation button 23 is pressed and moved to the back of the cap body 2, the cap body 2 is removed and fitted into the rear end of the pen body 1, whereby weight parts are arranged at both ends. So you can freely turn the pen while writing, and it is necessary to change the shape (remove or attach the cap body) depending on the usage (writing, pen turning) like a conventional pen turning writing instrument. Thus, it is possible to provide a writing instrument A for pen turning which can change the mood and unconsciously enjoy turning the pen while working or studying.
