【考案の詳細な説明】（産業上の利用分野）この考案はノツク式筆記具、特に水性インキ使
用のボールペンのインキ芯を収納したノツク式筆
記具に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a nok type writing instrument, particularly a nok type writing instrument that houses the ink core of a ballpoint pen using water-based ink.

（従来の技術）従来よりノツク式の筆記具は数多く考案されま

しまい服を汚損してしまう虞れがあつた。(Prior art) Many knuckle-type writing instruments have been devised and are on the market, but when a ballpoint pen that uses water-based ink is incorporated into this type of mechanism, there is no problem with normal knuckle operation, but the pen tip may accidentally fall into the main body. If the pen was carried in a pocket of clothes with the pen protruding from the shaft, there was a risk that the fabric of the pocket would absorb ink from the tip of the pen, staining the clothes.

そこで、クリツプを開脚することによりペン先
が本体内に収納される構造のノツク式水性ボール
ペンが考案され市販されている。 Therefore, a lock-type water-based ballpoint pen has been devised and commercially available, in which the pen tip is housed within the main body by opening the clip.

The ink core could not be retracted into the main body, which caused the inconvenience of having to change the pen each time. This invention is an attempt to improve the above-mentioned problems, and not only allows the writing to appear and disappear, but also allows the writing to be immersed in the pocket when inserted into the pocket.

ある。(Means for solving the problem) For this purpose, a locking groove and a vertically elongated engagement groove are provided on the outer periphery of the cam body of the conventional writing part retracting mechanism, and when the cam body is retracted, the cam body is moved forward while pressing the knob bar. Lock the clip point in the above locking groove,
The ink core is also immersed into the shaft by opening the legs by inserting the clip point into the pocket.

The rear end of the knock rod 1 is made to protrude from the rear end of the cam body 4, and the collar 1a of the knock rod 1 is brought into contact with the inner wall 4a of the rear end of the cam body 4. Next, the cam body 4
A longitudinally elongated engagement groove 5 is provided on the outer surface of the cam body, and the engagement groove 5 is engaged with a protrusion 7 protruding from an appropriate position on the inner surface of the main body shaft 6, so that the cam body 4 can be slid in the axial direction. Push in freely from the rear end surface of the main body shaft 6. A clip 9 having a clip point 8 is held in front, and a crown 1 whose inner diameter is smaller than the outer diameter of the cam body 4 is held.
0 from the rear end of the main body shaft 6. A through hole 11 is formed on the outer periphery of the main body shaft 6 where the clip point 8 is located, and a stepped portion 6a is provided at a position where the forward movement of the cam main body 4 is stopped. Also, the spring 12 that presses the knock rod 1 backward is connected to the cam body 4.
It is installed between the rear end surface and the knock cap 13, and the knock cap 13 is fitted onto the knock rod 1.

そして、本体軸６の前方よりインキ芯１４を挿

ない。 Since this device is constructed as described above, when writing, by pressing the knob cap 13, the knob rod 1 connected to the knob cap 13 pushes the rotor 2, and when pressed further, the rotor 2
is locked in the cam body 4, and the pen tip 17 protrudes from the tip of the metal tip 16 to be in a writing state. At the same time, the front edge 13a of the lock cap 13 comes into contact with the rear end surface 4b of the cam body 4 and pushes the cam body 4 forward so that the locking groove 3 of the cam body 4 matches the position of the through hole 11 provided in the body shaft 9. , the protruding end 8a of the clip point 8 fits into the locking groove 3 of the cam body 4.
Even if the knock cap 13 and the knock rod 1 are fitted into each other and the pressure on the knock cap 13 is released, the collar 1a of the knock rod 1 will not touch the inner wall 4a of the rear end of the cam body 4.
The cam body 4 is pushed back until it touches the cam body 4.
is locked at the tip 8a of the clip point 8,
The rotor 2 is also locked and becomes ready for writing as shown in FIG. The front end of the cam body 4 contacts a step 6a provided on the body shaft 6 and does not move forward any further.

When the clip 9 is opened in an attempt to carry it in a pocket or the like while it is still protruding, the protruding end 8a of the clip point 8 is disengaged from the locking groove 3 of the cam body 4, and the cam remains locked. The rear end surface of the cam main body 4 of the main body 4 retreats to the front end surface of the crown 10, and at the same time, the pen tip 17 is stored in the tip fitting 16, so that the pen tip 17 protrudes and stains fabrics such as pockets. Never.

尚、第３図の状態でクリツプポイント８を解除
すると第１図の状態に戻る。 If the clip point 8 is released in the state shown in FIG. 3, the state returns to the state shown in FIG. 1.
