The present invention relates to a pencil-type pencil and a ballpoint pen of the present invention, and to a pencil-type pencil having different pencil diameters or different pencil-shape pencils or ballpoint pens, which can be used in combination. It relates to a compound writing instrument.

The conventional composite writing instrument is configured such that, for example, two ball-point pen writing members having different ink colors by knock operation of the knock portion are alternately projected from the front end of the body each time the knock operation is performed by the operation of the rotary cam mechanism.

However, each time the knock operation is performed, the writing member is configured to alternately appear from the front end of the writing instrument body. Therefore, when the sharp pencil and ballpoint pen are combined, the front end is stored without the sharp pencil pen tip. You can't take notes. In addition, since the cam body provided on the writing instrument body and the rotating cam mechanism including the rotating cam and cam via are adopted, the configuration is complicated, and it is not easy to select the desired writing member on the fly as well as to make it flat.

The present invention composite writing instrument is devised to solve the above problems, while the plurality of writing members (2, 3) is fitted in the body (1), the rust on the back of each of the writing members (2, 3) Cylindrical members 6 and 7 having claws 4 and 5 are fitted, and partition members 23 for partitioning the respective writing members 2 and 3 are provided in the body 1, thereby providing the partition members. Between the front end portion 24 of the 23 and each cylindrical member 6, 7 springs 8, 9 for pushing the writing members 2, 3 back, respectively, are mounted on the body 1, respectively. When the projections 12, 13 of the hook pieces 10, 11 formed on the cylindrical members 6, 7 are protruded or attracted to the front ends 14, 15 of the respective writing members 2, 3, respectively. The first through holes 16 and 17 and the second through holes 18 and 19 to be engaged are formed.

In the present invention configured as described above, to select and use a desired writing member, for example, when the knock portion 4 of the writing member 2 is knocked against the spring 8, the writing member 2 moves in the front direction. The front end portion 14 protrudes from the front end of the body 1, in which case the projection 12 is separated from the second through hole 18 and is engaged with the first through hole 16 so that the writing member ( The front end 14 of 2) is maintained in the protruding state.

On the other hand, to attract the front end portion 14, pressing the front end portion of the clip 22, the projection 12 is formed in the upper end portion of the front end of the clip 22, the projection 12 is caught in the first through hole 16 ), The projection 12 is released from the first through hole 16, and as a result, the writing member 2 is moved backward by the spring force of the spring 8 so that the front end portion 14 is moved to the body. (1) It is drawn into the bar, whereby the projection 12 is engaged with the second through hole 18 and caught by the rear end of the second through hole 18.

Therefore, the writing member 2 is not feared to escape to the back of the body (1).

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view showing one embodiment of the present invention composite writing instrument, and FIG. 2 is a side cross-sectional view showing an axis writing line of a writing instrument for a pencil, which is one writing member 2, and FIG. A side cross-sectional view, and FIG. 4 is a front view of the present embodiment, taken along the axial center line of the writing member for ballpoint pen, which is the member 3.

First, the configuration of the embodiment shown in FIGS. 1 to 3 will be described.

In the drawings, reference numeral 1 is a writing instrument body having a flat shape, and 2 and 3 are two writing members respectively installed in the body 1, and in this embodiment, one writing member 2 is a writing member for a pencil pencil. Although the other writing member 3 is a ballpoint pen writing member, these writing members 2 and 3 may be combined with pencils or ballpoint pens having different core diameters or different colors. In addition, although the writing members 2 and 3 are also made into two pieces, it can of course also be more than that if necessary.

The cylindrical portions 6 and 7 of the knock members 4 and 5 (see FIGS. 5 and 6) are fitted to the rear portions of the writing members 2 and 3 to protrude from the body 1. A part of the knock cap 27 is inserted into the part, and the knock cap 27 writes for the pencil pencil and the ball pen when the color of the knock pencil portion 4 and the ball pen knock portion 5 is different from each other. It is convenient to select and use the members 2 and 3.

Here, the mechanical pencil knock cap 27 serves to prevent the lead in the lead storage tank 29 of the writing member 2 from escaping to the rear, as well as removing the knock cap 27. You can easily refill your heart.

However, the knock cap 27 is not necessarily required, and if the knock cap 27 is not present, the lead in the lead storage tank 29 escapes backward, so that the rear end portion of the knock portion 4 is shown in FIG. When the inner shape of the anchor is blown forward to form a hole (30a) enough to pass through it without difficulty, it is necessary to refill the core through the hole (30a) of the anchor portion (30) It is possible, but there is no fear that the lead inside the lead storage tank 29 will escape.

In addition, the body 1 is provided with a partition member 23 (see FIGS. 1 and 7) for partitioning each of the writing members 2 and 3, and the front and rear portions of the partition member 23 are each written member ( The support part 24 and the clip 22 which penetrate 2 and 3 are connected, and the front end support part 24 of this partition member 23, and the cylindrical member of each knock part 4 and 5 are provided. Between 6 and 7, springs 8 and 9 are provided to elastically push the writing members 2 and 3 back.

Further, at the rear portion of the body 1, the projections 12 and 13 of the locking pieces 10 and 11 formed by cutting the cylindrical members 6 and 7 are respectively written. The first through holes 16 and 17 and the second through holes 18 and 19 are formed to be fitted when the front ends 14 and 15 of the members 2 and 3 protrude or are drawn in, respectively. In addition, the front end inner surface of the clip 22 is a projection (12, 13) to release the engaging state by pressing the projections (12, 13) caught in each of the first through holes (16, 17) or each of the second through holes (18, 19) ( 20) is formed.

In addition, a locking hole 25 is formed at the rear side of the body 1, and a locking piece 26 (see also 7a, b) that is caught by the locking hole 25 is formed in the partition member 23, The locking piece 26 is caught in the locking hole 25 to prevent the partition member 23 from coming off to the rear. Of course, even if this engaging piece 26 and the engaging hole 25 are not formed, it has the knock part 4 and 5 at the back of both of the partition members 23 provided with the front support part 24, and the protrusion 12 in the center part 12 , And having the engaging pieces (10, 11) having a 13, the cylindrical members (6, 7) fitted to each of the writing member (2, 3) in front is provided, the front end portion of the partition member (23) Since the springs 8 and 9 are disposed between the 24 and the cylindrical members 6 and 7 to push the writing members 2 and 3 to the rear, the partition member 23 or the clip 22 is rearward. Although the force against the spring is applied to the elastic force by the springs (8, 9) to prevent the partition member (23) and the clip (22) from being pulled out of the body (1). Since it is conceivable, the springs 8 and 9 may be fitted by means of ribs or the like by the elastic force.

Next, the operation of the present embodiment configured as described above will be described.

If the writer knocks the knock portion 4 of the sharp pencil writing member 2 against the spring force of the spring 8 so as to use the sharp pencil writing member 2 as the writing member desired, for example, the writing member (2) is moved in the fore direction and the fore end portion 14 protrudes from the fore end of the body (1), wherein the knock portion (4) and the projection (12) is separated from the second through hole (18) As a result, the front end portion 14 is engaged with the first through hole 16 so as to protrude.

As described above, when the front end portion 14 of the mechanical pencil writing member 2 protrudes from the front end of the body 1, the knocking portion 4 is knocked like the known mechanical pencil, and the writing member ( 2) The chuck against the chuck impingement spring 28 or by its resilience force is mounted on the front part of the core storage tank 29, and the chuck inserted in the chuck ring is moved forward and backward to open and close the chuck so that the front end part 14 Will be dismissed from.
