In this case, the pen cores 11 and 12 may be selected in the same or different types from the group of ball pens, sine pens, highlighters, sharp cores, pencil cores, colored pencils, neutral pens, free pens, brush pens, magic pens, luminous pens, and the like.

According to the present invention, the central shafts 11a and 12a of each of the pen cores 11 and 12 are respectively inclined with the central axis 10a of the body 10 by a fixing stand 20 inside the body 10. It is fixed to hold (α). When the inclination angle α is 0, the pen cores 11 and 12 are in parallel with the central axis 10a of the body 10 as in a general writing implement, and as the inclination angle α is increased or decreased, the pen tips 11b and 12b are moved. It will be collected or opened up.

In addition, according to the present invention, the central axis 10a of the body 10 has a ground surface S in a state in which all of the nibs 11b and 12b of the cores 11 and 12 are in contact with the ground S. The predetermined tilt angle β is maintained. This is to maintain the inclination angle β between the body 10 and the ground S in a user-friendly state. The inclination angle is changed when the total lengths of the pen cores 11 and 12 including the tip 11b and 12b are different. (β) is regulated.

Although the inclination angle α (β) is sold in a state determined according to the type and length of the pen cores 11 and 12, the pen cores 11 and 12 can be detached from the holder 20 or 20a due to the structure. It is also possible to vary to some extent during use. It is preferable to form the fixtures 20 and 20a in a structure that press-fits the pen cores 11 and 12 as compared with a structure in which a spiral structure or other separate parts are interposed therebetween. In addition, the fixing stand 20, 20a is preferably formed in the middle portion of the writing instrument may be formed in the end portion. If the pin press-fitted into the hole of the pen core 11, 12 is provided in the fixing stand 20, it is more advantageous for a downsizing design.

Figure 2 is a block diagram showing the arrangement of the pen core in the writing instrument according to the present invention, Figure 3 is a block diagram showing the arrangement of the pen core according to a modification of the present invention.

First, the pen cores 11 and 12 of the present invention may be configured to be exposed at a predetermined distance from the central axis 10a of the body 10. 2 shows an example of symmetrical arrangement in which the cores 11 and 12 are located at the same distance from the central axis 10a, and FIG. 3 shows the cores 11 and 12 at different distances from the central axis 10a. This is an example of an asymmetrical arrangement. 2 (a) and 3 (a) are front views, and the rest are bottom views.

In FIG. 2, (a) is a configuration in which two identical lead cores 11 and 12 are spaced apart from each other, (b) is a configuration in which two other kinds of lead cores 11 and 12 are spaced apart from each other, and (c) The other three kinds of pen cores 11 and 12 are arranged to be spaced apart in a triangular form, and (d) is a structure in which two kinds of pen cores 11 and 12 having different thicknesses are arranged to be spaced apart in pairs.

In FIG. 3, (a) shows that a first pen 11 such as a double pen (for example, a highlighter) is disposed on one side of the central axis 10a, and another type of second pen core 12 is on the other side of the central axis 10a. It is arranged in the configuration. (b) is the structure by which the several 1st pen tip 11 of the same kind and different thickness is arrange | positioned at one side, and one 2nd pen tip 12 is arrange | positioned at the other side. Although FIG. 3 has been described as a modification of FIG. 2, it may be classified into the same category in that the cores 11 and 12 are not disposed on the central axis 10a as shown in FIG. 2.

Figure 4 is a block diagram showing the arrangement of the lead according to another modification of the present invention.

In another modified embodiment of the present invention, the pen cores 11 and 12 are exposed to the first pen core 11 exposed on the central axis 10a of the body 10 and around the first pen core 11. The structure provided with the some 2nd pen tip 12 is also possible. In FIG. 4, the same thicknesses are arranged in a straight line as shown in (a), the different thicknesses are arranged in a straight line as in (b), or three-dimensionally arranged different in thickness as in (c). 4 is generally suitable for arranging the most characteristic (eg thickest or darkest color) first nib 11 on the central axis 10a.

At this time, according to the present invention, the inclination angle α of the pen cores 11 and 12 is within a range of ± 5 °. In FIG. 1, the central axes 11a and 11b of the pen cores 11 and 12 are the body 10a. It is represented by + when it is far from the central axis 10a of) and by when it is approached. When the thick pen cores 11 and 12 are accommodated in the body 10, the gap between the pen tips 11b and 12b is widened, so that the inclined angle α is a positive value and the tip 11b and 12b are provided. Can be collected. On the contrary, in the case of using the thin pen cores 11 and 12, the inclined angle α may be set to a negative value so that the pen cores 11 and 12 may be opened.
