Further, cam surfaces 82a and 82b are formed on the rear end sides of the moving bodies 8a and 8b so as to taper toward the rear ends in contact with each other, and the moving bodies 8a and 8b corresponding to the cam surfaces 82a and 82b are formed. Engagement recesses 83a and 83b are formed on the side surfaces of the two abutting each other. Coil springs 9a and 9b are provided outside the writing bodies 7a and 7b to constantly urge the writing bodies into the container body.

  A pin 10 that acts on the cam surfaces 82a and 82b of the moving bodies 8a and 8b is provided on the surface of the rotating body 2 facing the container body 1, and the pin 10 attaches the writing bodies 7a and 7b to the container body 1. From the housed state, the rotation locus E (FIG. 1) passing through the engagement recesses 83a and 83b is rotated around the support shaft 3, and this rotation causes the pin 10 and the cam surfaces 82a and 82b to rotate. The cursive projecting means is configured.

  As shown in FIG. 8, the attachment portion 1 </ b> B- 1 of the support shaft 3 of the container body 1 is formed with a step 15 a having a peripheral portion of the hole 15 passing through the support shaft 3 that is lower by about the thickness. On the other hand, the rotating body 2 is continuously formed with a large-diameter hole portion 21a that communicates with the head 3a of the support shaft 3 and a small-diameter hole portion 21b that communicates with the shaft portion 3b. A cylindrical convex portion 22a to be fitted to the step 15a is formed around the small diameter hole portion 21b on the mounting surface side.

  The support shaft 3 includes a large-diameter head portion 3a and a small-diameter shaft portion 3b. The small-diameter shaft portion 3b is formed in at least two parts, and an engagement stage that protrudes laterally at an intermediate portion thereof. A portion 3c is formed, and is formed on a tapered slope 3d from the engaging step portion 3c toward the tip of the shaft portion 3b.

  Next, assembly of the writing bodies 7a and 7b to the container body 1 and assembly of the auxiliary tools H1 and H2 to the storage space 5 will be described. First, the rear ends of the writing bodies 7a and 7b are inserted and fixed in the concave portions 81a and 81b of the moving bodies 8a and 8b to constitute a writing set. Then, the coil springs 9a and 9b are fitted on the cursive bodies 7a and 7b, respectively, and the curly bodies 7a are inserted into the recesses 12a and 12b of the lower receiving portion 1B which is a component of the container body 1 while the coil springs 9a and 9b are compressed. 7b and the movable bodies 8a and 8b are assembled in the hollow 11 of the lower receiving portion 1B. Next, the upper lid portion 1A is overlapped so as to cover the open surface side of the lower receiving portion 1B, and the abutting portions of the both members are integrally fixed by a known means such as welding, adhesion, or uneven engagement.

  Then, the cylindrical convex portion 22a around the hole provided on the one end side of the rotating body 2 is fitted to the step 15a around the hole 15 provided on the one end side of the container body 1 incorporated in this way, The moving body 2 is superposed on the container body 1, and the small-diameter shaft portion 3b of the support shaft 3 is pushed into the center hole 22b of the fitted cylindrical convex portion 22a. Since this small-diameter shaft portion 3b is divided into two and is formed on the tapered slope 3d, it progresses while reducing its diameter, and after passing through the center hole 22b, it is elastically restored and protrudes to the side. The engaging step portion 3c engages with the inner surface of the hole edge of the container body 1 to prevent it, and the large diameter head portion 3a of the support shaft 3 and the engaging step portion 3c connect the container body 1 and the rotating body 2 to each other.

In the use state, the spacing member 6c also functions as a stopper for receiving the back surfaces of the auxiliary tools H1 and H2 and maintaining the auxiliary tool in the use state, as shown in FIG.

  A usage pattern of the first embodiment configured as described above will be described. When not in use, as shown in FIGS. 1 to 3, the rotating body 2 is folded so as to overlap the container body 1. In this state, as shown in FIG. 1, the pin 10 of the rotating body 2 is located at a position where it does not act on the cam surfaces 82a and 82b of the moving bodies 8a and 8b. For this reason, the moving bodies 8a and 8b are pulled into the container main body 1 until the rear ends abut against the support shafts by the elastic restoring force of the coil springs 9a and 9b. It is not limited to contact with the support shaft 3, and a rib may be provided in the container to make contact. As a result, the writing bodies 7 a and 7 b integrated with the moving bodies 8 a and 8 b are also drawn into the container body 1.

  Next, when using the writing body 7a (for example, black writing body), if the rotating body 2 is rotated 180 degrees clockwise as shown in FIG. 5, the rotating body 2 is near the end of the rotation. The pin 10 comes into contact with the cam surface 82a at the rear end of the moving body 8a. Thereafter, the moving body 8a is advanced against the elastic force of the coil spring 9a as the rotating body 2 continues to rotate, and the writing body 7a. The front end of the container is protruded out of the container body 1. And in the position which the rotation body 2 rotated 180 degree | times, the pin 10 of the rotation body 2 engages with the engagement recessed part 83b formed in the side surface of the movable body 8b, and rotation of the rotation body 2 is carried out.

When the rotating body 2 is rotated, the pin 10 comes out of the lower receiving portion 1B from the lacking portion 1B-2 of the side wall of the lower receiving portion 1B, rotates on the rotating locus E, and again lacks the other. It rotates so that it may enter in the lower receiving part 1B from the part 1B-2.

  Next, when using the opposite writing body 7b (for example, red writing body), if the rotating body 2 is rotated 180 degrees clockwise as shown in FIG. Then, the pin 10 of the rotating body 2 comes into contact with the cam surface 82b at the rear end of the moving body 8b, and then the moving body 8b is advanced against the elastic force of the coil spring 9b as the rotating body 2 continues to rotate. The tip of the writing body 7b is projected out of the container body 1. And in the position which the rotation body 2 rotated 180 degree | times, the pin 10 of the rotation body 2 engages with the engagement recessed part 83a formed in the side surface of the moving body 8a, and rotation of the rotation body 2 is carried out. The position is fixed.

  Then, the rear end of the moving body 8b to which the elastic force of the coil spring 9b is constantly applied to the inside of the container body 1 comes into contact with the protruding portion of the pin 10 engaged with the engaging recess 83a, so that the moving body 8b moves backward. The cursive body 7b is held in the protruding position, and the same effect as when the cursive body 7a is put into use can be obtained.

As described above, according to the first embodiment, when the writing body 7a is put into use, the rotating body 2 is also rotated and held in a state of being linear with the container body 1, so that the container body 1 is attached to the fingertip. When the handle is held in place, the support shaft is just in the hand and easy to write. Further, since the rear end of the moving body 8a abuts against the protruding portion from the engaging recess 83b of the pin 10 to stop the moving body 8a from retreating, even if the writing body 7a is strongly pressed against the writing surface during writing The body 7a does not retreat into the container body 1 and can always be written stably. In addition, since the rotation trajectory E of the pin 10 of the rotating body 2 is configured to pass outside the container body 1, the width of the container body 1 only needs to be large enough to accommodate the moving bodies 8a and 8b. The width can be made as small as possible, and the overall shape can be made elongated and suitable for writing.

  When not in use, by folding the rotating body 2 so as to overlap the container body 1, all the writing bodies 7 a and 7 b are also drawn into the container body 1 so that the entire length becomes the length of the container body 1. Folded small, compact and suitable for carrying. Then, by rotating the rotating body 2 180 degrees clockwise or counterclockwise, the writing bodies 7a and 7b can be alternately written, so that handling is easy.

  On the other hand, when the auxiliary tool H is used, the rotating body 2 is folded so as to overlap the container body 1 and the writing bodies 7a and 7b are stored in the container body 1 as shown in FIGS. As shown in FIG. 2, the auxiliary tool H <b> 1 is rotated about the attachment shaft 6 d <b> 1 and protrudes from the storage space 5 to the outside. In this state, the rotating body 2 and the protection body 4 overlapping the top and bottom of the container body 1 are gripped and used. In this case, even if a force is applied to the auxiliary tool H, the back surface of the auxiliary tool H abuts against the spacing member 6c and further rotation is prevented, so that a large force can be applied to the auxiliary tool H1 and easy to use. It is.
