That is, the concave vertices of the teeth 72 and the vertices of the inclined surface 82 of the knock protrusion 81 do not coincide with each other in a state in which the elastic force of the elastic member 4 is actuated so as to be offset from each other.

When formed as described above, the inclined surface 82 and the teeth 72 inclined to each other when the elastic force of the elastic member 4 acts to slide, but the moving projection 73 of the pressing member 7 is guide groove 66 The rotation force is applied to the rotating member 8 because the rotation of the pressing member 7 is restricted.

The pressing member 7 is formed in a hollow cylindrical shape, and the upper portion of the knock member 8 is formed to be inserted into the pressing member 7.

Next will be described the operation process of the deep-rotating writing instruments according to the present invention configured as described above.

First, when the user presses the pressing member 7 to write in the storage state as shown in FIG. 4, the pressing member 75 of the pressing member 7 and the moving member 6 in contact with the upper surface move forward. .

As described above, when the moving member 6 moves forward and the fixing protrusion 63 moves downward than the locking protrusion 53 of the clip 5 ring 52, the fixing protrusion 63 is described above. Even if the locking projection 53 is removed and the force applied to the pressing member 7 is removed, the fixing projection 63 is prevented from returning upward by being caught by the locking projection 53. It becomes

When the force applied to the pressing member 7 is removed in the above, the writing core 2 is moved backward by the elastic force of the elastic member 7, and the above rotation in contact with the upper surface of the writing core 2 The member 8 and the pressing member 7 are moved backwards, and the tip 21 of the writing lead 2 is in a released state (see FIG. 3) completely concealed into the cap 3.

At this time, the pressing member 7 moves forward and backward in the longitudinal direction of the outer cylinder 1 along the guide groove 66 because the moving projection 73 is inserted into the guide groove 66 of the moving member 6. .

In addition, the rotation member 8 is also inserted into the guide groove 66 of the moving member 6, the knock projection 81 is moved forward and in the longitudinal direction of the outer cylinder (1) along the guide groove (66) Move backward.

When the user presses the pressing member 7 for the first time in the released state (see FIG. 3), the rotating member 8 in contact with the pressing member 7 moves downward, and the writing lead 2 The elastic force of the elastic member 4 is overcome and moved toward the cap 3 so that the tip 21 of the writing lead 2 is exposed to the outside of the cap 3.

The inclined surface 82, which is the upper end surface of the knock protrusion 81 of the rotating member 8, is positioned below the inclined surface that is the lower end surface of the guide protrusion 64 of the moving member 6 (knock of the rotating member 8). When the projection 81 is positioned downwardly away from the guide groove 66, the rotation member 8 has the vertex of the inclined surface 82 of the knock projection 81 and the vertex 72 of the tooth 72 of the pressing member 7.

When the force that pressed the pressing member 7 in the above state is removed, the rotating member 8 moves backward by the elastic force of the elastic member 4 transmitted through the writing core 2, but the knock protrusion Writing 81 is caught by the return preventing projection of the moving member 6, the movement is constrained, and the moving member 6 is locked by the locking projections 53 of the clip 5, the movement is constrained The writing state (see Fig. 2) in which the tip 21 tip of (2) is exposed to the outside of the cap 3 is maintained.

At this time, the pressing member 7 is in a state capable of freely moving up and down between the rotary member 8 and the stopper 51 of the clip 3 because the moving projection 73 is not caught by the return preventing projection.

In the writing state as described above (see FIG. 2), when the user writes and presses the pressing member 7 again for storage, the rotating member 8 moves forward, and the knock protrusion 81 is described above. Departure from close contact with the return preventing projections.

At this time, the rotating member 8 is rotated again while the knock protrusion 81 is located in the guide groove 66 is not formed over the guide projection 64, the return preventing projection is formed.

As the rotating member 8 rotates in the above, the writing lead 2 also rotates again at an arbitrary angle.

When the force that pressed the pressing member 7 in the above state is removed, the writing lead 2 is moved backward by the elastic force of the elastic member 4, and the rotary member 8 and the pressing member 7 are sequentially Moving backward, the tip 21 of the writing lead 2 is in a released state (see FIG. 3), which is completely concealed into the cap 3.

At this time, since the knock protrusion 81 is located in the guide groove 66 in which the return preventing protrusion is not formed, the backward movement of the rotating member 8 is also smoothly performed.

As described above, the pressing member 7 is repeatedly pressed first and second times, so that the writing state (see FIG. 2) and the release state (see FIG. 3) are repeated.

While writing in the above-described writing state (see FIG. 2), while the user does not press the pressing member 7 a second time so as not to be released (see FIG. 3), the clip 5 can be inserted into a collar or a pocket. When lifting the ring 52 of the c) away from the outer cylinder 1, the fixing projection 63 is released from the state caught by the locking projection 53, the rotating member by the elastic force of the elastic member (4) (8) moves backward, the moving member 6 is moved with the rotating member (8) because the knock projection (61) is caught in the return preventing projections, the tip 21 of the writing lead (2) ) The end is in a storage state (see FIG. 4) where the end is completely concealed into the cap 3.

In the above described one embodiment of the deep-rotational writing instruments according to the present invention was configured as a safety knock type, the present invention is not limited to this, it is possible to apply to the knock-type writing instruments different from the one embodiment described above. Do.

In the above description of the preferred embodiment of the cardiac rotary writing implement according to the present invention, but the present invention is not limited to this, it is possible to carry out various modifications within the scope of the utility model registration claim and the detailed description of the invention and the accompanying drawings. This also belongs to the scope of the present invention.

According to the deep-rotating writing implement according to the present invention made as described above, the rotary member is rotated by a predetermined angle in accordance with the pressing member for writing, the end of the rotary member is inserted into the end of the writing core is a rotating member By the friction between the writing core and the writing core, the writing core also rotates at a predetermined angle.

At this time, since the angle at which the writing core rotates is generated between the rotating member and the writing core, the writing core does not coincide with the regular rotation angle of the rotating member and has an arbitrary random rotation angle.

Therefore, since the tip portion in contact with the ground during writing is changed every time the knock operation, only one side of the tip can be prevented from uneven wear occurring continuously in contact with the ground.

And since the fall of the ball caused by the uneven wear of the tip is prevented, the life is extended.
