なくなる虞れがあった。However, the cam structure of the above-mentioned conventional knock type writing instrument has a window hole of a shaft cylinder provided by separate processing or molding, and a cam hole provided inside the window hole. A clip for releasably engaging a locking claw which is shifted by a knocking operation of a knocking portion and a resilient force of a return spring so as to draw a series of cam tracks along an opening edge of the window hole forming a cam shape. Combination with the locking part. For this reason, dimensional problems due to respective processing or molding errors are likely to occur. For example, it is easy to cause a displacement of the engaging portion with respect to the window hole due to a processing or molding error, and since the conventional displacement cannot be corrected by the incorporating position, it is pushed back by the elastic force of the return spring. The locking claw which is moved forward by the knocking operation of the knocking portion from the retracted position causes a positional shift, and the locking claw is not locked to the locking portion or the locking state is unstable As a result, the locking state of the locking portion may be released during writing, and the locking claw may be pushed back to the retracted position by the elastic force of the return spring. That is, there is a possibility that a malfunction in use may occur, such that the pen tip of the ink storage tube may be immersed in the shaft cylinder during writing without the normal knock function operating normally. Such a problem is not limited to the dimensional error caused by the separate processing or the separate molding. In addition, in the case of the conventional knock-type writing instrument, the engaging claw always reliably moves forward by the knocking operation. Since there is no structure to hold the locking portion at a predetermined position where the locking claw can be securely locked, the locking portion may be misaligned from the predetermined position in long-term use, which may cause a problem. It is also conceivable that the above-mentioned problem may be caused. Therefore, in the related art, the original knock mechanism may not operate normally.

性）に難点を有していた。The locking claw in the above-described conventional knock-type writing instrument is provided on an ink storage tube that is rotatably mounted on a shaft cylinder, and the rear end of the locking claw constitutes a knock portion as it is. The window hole of the shaft cylinder, through which the locking claw is guided and shifted so as to draw a series of cam trajectories by the knocking operation and the resilience of the return spring, is linear in the axial direction as shown in FIG. At the front end sides of the opening edges 32 and 33 extending in parallel, a front end opening edge 34 that is directed obliquely forward from one side opening edge 32 to the other side opening edge 33 (referred to as a front wall in the published specification).
And a rear end opening edge 35 (referred to as a rear wall in the published specification) provided obliquely rearward from the other side opening edge 33 to the one side opening edge 32 on the rear end side of the both side opening edges 32, 33. ) Is formed in a substantially rhombic shape. Accordingly, by the knocking operation (pushing operation) of the knocking portion, the locking claw 31 is moved forward from the retreat position P along the opening edge 32 on one side of the window hole 30, and the window hole 30 is moved forward.
The pen tip is locked by the locking portion 36 of the clip incorporated in the 30 and protrudes from the tip end opening of the barrel. At this time, if the knocking operation force (pressing force) is not adjusted, the locking claw 31 moves forward beyond the locking portion 36 to the front end opening edge 34,
Further, when the knocking operation is released by moving forward along the inclination of the front end opening edge 34, and the knocking operation is released in this state, it is pushed back to the rear end opening edge 35 by the elastic force of the return spring, and along the inclination of the rear end opening edge 35. Therefore, there is a possibility that erroneous operations such as returning to the retreat position P may occur frequently, and there is a problem in reliability (reliability).

In the linked state, a knock portion is provided at the rear end of the barrel, and the knock portion is provided with a locking claw, which is formed on an inner surface portion of the clip facing the inside of the barrel through a window hole of the barrel. The pen tip is protruded from the tip end opening of the barrel by being detachably engageable with the locking portion and being locked by the locking portion. The locking claw is locked to the stop and the locking state is released, and the locking state is released by the flip-up operation of the clip. On the front side of the knock portion provided at the front in the axial direction toward the window hole of the barrel. An extended elastic arm piece is protruded, and a locking claw is provided at a protruding end of the elastic arm piece. On the other hand, an inner surface of the clip facing the inside of the barrel through a window hole of the barrel is provided with an engaging member. The locking claw has a locking portion for locking and disengaging the locking claw, and the locking claw is formed by at least the return spring by the knocking operation of the knocking portion, the elastic restoring force of the elastic arm piece, and the resilient force of the return spring. The pen tip of the ink container tube is guided and shifted stepwise in a forward range from the retreat position where the retreat is caused by the elastic force to reach the locking portion and a retreat range from the locking portion to the retreat position. It is provided with a cam section having an in-and-out guide means for guiding a cam locus corresponding to the in-and-out operation to be in and out of the tip end opening of the cylinder. According to such a technical means, the knocking operation of the knocking portion for causing the pen point immersed in the barrel to protrude from the tip opening of the barrel is performed, and the knocking operation is continued to a certain area. When released later, the locking claw that stands by at the retreat position draws a cam trajectory that draws the pen tip from the tip opening of the barrel by the cam formed on the inner surface of the clip facing the window of the barrel. The guide is shifted (advanced) by the means, and is abutted and locked to the locking portion by the elastic restoring force of the elastic arm piece and the resilient force of the return spring stored by the guide shift. In this manner, the engagement claw is guided and shifted by the emergence guide means that draws a cam miracle, so that the pen tip of the ink storage tube is held in a protruding state protruding from the distal end opening of the barrel. On the other hand, when the knocking operation of the knocking part that causes the protruding pen tip to be immersed in the shaft cylinder is performed, and when the knocking operation is continued to a certain area and then released, the engaging part locked by the locking part is engaged. The pawls are guided (retracted) by the projection / retreat guide means which draws a cam trajectory that causes the pen tip protruding by the cam portion to enter from the tip end opening of the barrel, and disengages from the locking portion by the guide transfer. After being disengaged, it is retracted to the retracted position by the elastic restoring force of the elastic arm piece and the elastic force of the return spring.
In this manner, the locking claw is disengaged from the locking portion and is guided and shifted by the retreating guide means that draws a cam miracle, so that the pen tip of the ink storage tube is retracted into the shaft cylinder from the tip end opening. The release of the locking claw from the locking portion is also performed by a flip-up operation of the clip. That is,
The locking claw is instantaneously disengaged and released from the locking portion by opening the clip by putting it in a clothes pocket or the like, and from the locking portion position by the elastic restoring force of the elastic arm piece and the elasticity of the return spring. Returned directly to the retracted position.

First, the pen tip 2-1 immersed in the barrel 1 is moved to the position of the barrel 1. When the knocking operation of the knocking portion 4 is performed so as to protrude from the distal end opening 1-1 (the state shown in FIG. 1A), the locking claw 8 waiting at the retreating position P moves from the retreating position P to the guide inclined portion 24. The cam portion 10 is guided to move forward to the first guide portion 10-1, and the first
By the knocking operation continued along the guide portion 10-1, the guide is shifted obliquely forward (the state shown in FIG. 5B) and continuously forward along the second guide portion 10-2 provided continuously. The guide will be transferred to. The movement of the locking claw 8 causes the pen tip 2-1 to move.
Is projected from the tip opening 1-1 of the shaft cylinder 1, and the elastic arm piece 9 is gradually deformed into a substantially arcuate shape. That is, the elastic restoring force is gradually stored in the elastic arm piece 9. Then, when the locking claw 8 that has been guided and shifted forward along the second guide portion 10-2 is brought into contact with the regulating portion 16 in front thereof after passing through the second guide portion 10-2, The forward shift is stopped (the knocking operation of the knocking section 4 is stopped). When the knocking operation is released in this state, the locking claw 8 moves obliquely rearward along the third guide portion 10-3 by the elastic restoring force stored in the elastic arm piece 9 and the elastic force of the return spring 3. The guide is then shifted to the stop portion 7 at the end of the guide to make an abutment lock (the state shown in FIG. 5C). As a result, the barrel 1
The protruding state of the pen tip 2-1 protruding from the tip opening 1-1 is maintained (the state shown in FIG. 1B). In other words, it is in a state where it can be written. On the other hand, when the knocking operation of the knocking portion 4 is performed so that the protruding pen tip 2-1 is immersed in the barrel 1, the locking claw 8 locked by the locking portion 7 is released from the locking portion 7. The guide is further moved axially forward along the fourth guide portion 10-4, and the locking state of the locking claw 8 with respect to the locking portion 7 is released.
Then, when the locking claw 8 guided and shifted forward in the axial direction along the fourth guide portion 10-4 passes through the fourth guide portion 10-4, its movement is changed by the protrusion 13 of the knock portion 4. While being engaged with the front end 11-1 of the slot 11 of the barrel 1, the locking arm 8 further acts on the elastic restoring force of the elastic arm 9 and the resilient force of the return spring 3. The guide is transferred to the fifth guide 10-5, and the guide is transferred to the sixth guide 10-6 along the fifth guide 10-5 (the state shown in FIG. 5D). The sixth guide portion 10-6 is formed by the elastic restoring force of the elastic arm piece 9 and the resilient force of the return spring 3 on which the locking claw 8 guided and transferred to the sixth guide portion 10-6 further acts. Along the crossing portion 21 of the first guide portion 10-1 to the retreat position P side while being guided by the inclined portion 22 on the lower surface thereof, and retreats to the retreat position P (FIG. 5).

能を正常に作動させる事ができる。The knock-type writing instrument of the present invention is constructed as described above, and has the following operational effects. A locking portion that locks a locking claw of a knock portion so as to maintain a state where the pen tip protrudes from the distal end opening of the barrel, and a locking portion that protrudes the pen tip immersed in the barrel from the distal end opening. The pawl is guided and shifted stepwise from the retracted position to the locking portion.
In other words, a cam portion having projection / retraction guide means for guiding a pen tip to protrude and retreat from the tip end opening of the barrel so as to draw a series of cam trajectories corresponding to the projection / retraction operation is provided through the window hole of the barrel. Since the clip is provided on the inner surface of the clip facing the inside of the cylinder, the positional relationship between the locking portion and the retracting guide does not cause a positional deviation due to processing or molding errors as in the related art. Therefore, the locking of the locking claw with respect to the locking portion and the movement of releasing the locking claw from the locking portion are ensured. That is,
The original knocking function that causes the pen tip to protrude and retract from the tip opening of the barrel can be operated normally.

待できる。Further, after the locking claw is guided and shifted from the locking portion of the cam portion along the fourth to sixth guide portions of the protruding and retracting guide means, it is provided at the inclined lower end portion by the return guide portion. Because the pen tip is retained in the concave notch portion at the retreat position P, the protruding state of the pen tip, in which the retaining claw is retained by the retaining portion, continues for a long time, and is substantially arcuate. Even if a deformation habit associated with the elastic deformation is attached to the elastic arm piece, the deformation habit is forcibly corrected by accommodating the locking claw in the concave portion. In other words, since the forcible portion is forcibly corrected to a linear posture (state) directed forward in the axial direction from the continuous portion (root) with the knock portion, the elastic restoring force of the elastic arm piece can be stably maintained for a long time. Can be Therefore, the reliability of the returning operation of the locking claw to the retracted position P using the elastic restoring force of the elastic arm piece can be expected for a long time.
