A collet chuck 5 for use is attached via a horizontal guide tube 6, and the lower end of the spare core storage tube 2 and the shaft tube 1 are attached on the outer periphery of the horizontal guide tube 6.
The spare core storage cylinder 2 is locked between the upper surface of the intermediate wall 7 in the
A spring 8 that returns the knocking member 3 and collet chuck 5, etc. upward is wound around it, and a cap 10 that moves up and is hidden inside the lower end of the shaft cylinder 1 and moves down and projects is inserted, and this cap Attach the rubber core holding ring 11 to the cap 10 and attach the rubber core holding ring 11 to the cap 1
0 is provided with a craftsman's recess 12 at the lower end of the collet chuck 5, a stepped portion 3 for tightening the tightening ring 3, and a stepped portion 14 for releasing the tightening of the tightening ring 4. A tightening ring-shaped driven body 1 is placed on the outside of the proximal ring-shaped portion of 5.
A clutch driving body 17 in the form of a collet chuck, which is equipped with The outer surface of the tip of the holder 19 is removably engaged with a locking groove 20 provided on the inner circumferential surface of the shaft tube 1.
A locking protrusion 2 that maintains the protruding state from the lower end of the shaft cylinder 1
1, and a stepped portion 22 for tightening the clutch follower 16 on the inner surface of the distal end of each elastic leg 19, and a stepped portion 22 of the clutch follower 16 on the inner surface of the proximal end of each elastic leg 19. Each elastic leg 19 is provided with a stepped portion 23 to eliminate tightening.
An overuse recess 24 of the clutch driven body 16 is placed in the middle of the inner surface of the
In addition, a sloped wall 25 is formed on the upper side of each of the overuse recesses 24, and the sloped wall 25 collides with the clutch driven body 16 when the base 10 is hidden, thereby tightening the clutch driven body 16 and tightening the collet. The chuck 5 is tightened by the tightening ring 4 at its tightening step 1.
It is designed to stop at a position where it does not collide with 3.

Although not shown in the figure, the cap 10 is prevented from rotating by slidably fitting the protrusion and the guide groove, etc.
In some cases, a backing or an elastic ring is attached to the tip of the barrel 1 to maintain a tight space between the inner surface of the gap and the outer surface of the cap 10 and prevent the cap 10 from wobbling. The structure for maintaining the collet chuck 5 in the released state during the hidden line is not limited to only the abutment between the inclined wall 25 and the clutch driven body 16, but other structures can also be used.

In the above embodiment, as shown in FIG. 1, by repeatedly applying a half-press operation to the knock member 3 and an operation to release the same press, the writing lead A is brought out and used for writing, and when not used for writing. In FIG. 1, the knocking member 3 is fully pressed to engage the locking part 23 and the locking receiving part 22 (see FIG. 2), and at the same time, the tip of the writing lead A and the tip of the cap 10 are pressed. Push the locking protrusion 21 from the locking groove 20 slightly with your finger etc.
After removing the knock member 3, the writing lead A and the cap 10 are brought into the preloaded state shown in FIG.
In the figure, the knock member 3 is fully depressed to engage the locking protrusion 21 with the locking groove 20.

As mentioned above, the cap of the present invention is concealable, so when carrying it in a pocket etc., the sharp cap can be pre-paid and this has the advantage of being extremely safe. However, as is particularly clear from the examples, there is a gap between the outer periphery of the spare core storage cylinder 2 and the inner periphery of the shaft cylinder 1, for example.
Since there is no cam device, spring, etc. as disclosed in No. 1-154236, it is possible to effectively increase the diameter of the spare core storage cylinder 2 and significantly increase the volume, which is advantageous.
