The present invention relates to a card-type writing instrument.

Various writing instruments have been proposed for carrying in the pockets of cloth, etc., but their shape is quite old, and the appearance of a more compact writing instrument has a novel shape that is at the cutting edge of the times and is convenient for carrying. This is the expected phenomenon.

The object of the present invention is to be constructed in view of such a phenomenon, and to provide a writing instrument having a novel phenomenon and extremely convenient for carrying a more compact form.

The gist of the present invention is characterized in that one or a plurality of flat writing elements are stored in a corresponding cut portion of a card-like case and are conveniently accommodated in a cut section so that the card can be integrated as a whole. There is an expression writing implement.

EMBODIMENT OF THE INVENTION Hereinafter, the Example shown by drawing in this invention is demonstrated.

1 to 3 is a perspective view for explaining the storage state of the composite writing instrument according to an embodiment of the present invention, Figure 4 is a front view in phase.

In the drawings, 1 is a card-like case, and the dimensions thereof are not necessarily limited, but are roughly convenient for storing in a small thing such as a commuter pass or a business card, for example, a telephone card or a credit card. It is about 5 cm long and 8 cm wide and 2 to 3 mm thick, and the material is plastic, for example.

In this case 1, the flat mechanical pencil element 2 and the ball pen element 3 having a shape as shown in the drawing are cut so that they can be freely put and pulled. It has parts 1a and 1b (FIG. 3).

On the inner circumferential surface in the longitudinal direction of the cut portions 1a and 1b, a pair of projections 1c, 1c, 1d and 1d facing each other are provided, and these projections, the mechanical pencil element 2 and the ball pen element ( The pair of concave grooves 2c, 2c, 3d, and 3d provided corresponding to both side surfaces of 3) are engaged with each other when these elements are inserted into the case 1 and stored therein.

Further, the front ends of the cut portions 1a and 1b are provided with holes 1e and 1f, respectively, and when the two elements are accommodated in the case 1, the prepayment 7 of the mechanical pencil element 2 is provided. And the ball pen chip 23 of the ball pen element 3 is accommodated in the drilled hole (see FIGS. 4 and 4a).

5 is a cross-sectional view taken along the line A-A of FIG. 4, FIG. 6 is a cross-sectional view taken along the line B-B of FIG. 4, and FIG. 7 is a cross-sectional view taken along the line C-C of FIG.

Next, the structure of the sharp pencil element 2 and the bowl pen element 3 is demonstrated based on drawing.

In the explanatory drawing of the green pencil element 2 of FIGS. 8 to 12, FIG. 8 is a plan view, FIG. 9 is a front view, FIG. 9A is a left side view, FIG. 9B is a sectional view taken along line AA of FIG. FIG. 9C is a right side view, FIG. 10 is a cross-sectional view taken along line BB of FIG. 9, FIG. 11 is a cross-sectional view taken along line CC of FIG. 8, and FIG. 12 is an explanatory view showing a pressed state of the rusted portion 10. FIG.

In the drawings, 4 is a pencil body; 4a is a mask plate covering the upper and lower sides of the pencil body.

This pencil body 4 is flat, as apparent from the figure, and its thickness almost corresponds to the thickness of the case 1.

In the main body 4, a chuck mechanism part consisting of the split click chuck 5 and the tightening ring 6 is incorporated, and the rear end of the split click chuck 5 is integrally shifted to the soft guide portion 9.

10 is a rusted portion that is connected to the lead guide portion (9).

An opening 11 for supplying the core 14 is provided at the top of the green portion 10, and the opening communicates with the guide steel 9a of the core guide portion 9.

The split click chuck 5 is provided with an engaging portion 12 at which one end of the spring 8 is engaged, and an engaging portion 13 at which the other end of the spring 8 is engaged inside the pencil body 4. ), The split click chuck 5 is exerted by the spring 8 in the retraction direction, and is normally in the state shown in FIG. 11, and the core 14 is gripped by the chuck mechanism. have.

The chuck mechanism is reciprocated in the axial direction of the mechanical pencil element 2 by the rusting operation of the rusting portion 10 as usual, so that the lead 14 is continuously exported to the writing position (Fig. 12). Reference). 15 is a year holder.

Next, the structure of the ball pen element 3 will be described based on FIGS. 13 to 16.

FIG. 13 is a plan view, FIG. 14 is a front view, FIG. 14A is a left side view, FIG. 14B is a sectional view taken along line AA of FIG. 14, FIG. 14C is a right side view, FIG. 15 is a sectional view taken along line BB of FIG. It is sectional drawing along the CC line of FIG.

21 is a bowl pen body, 22 is an ink receiving tube embedded in the inner lumen of the bowl pen body, 23 is a ball pen chip, and 21a is a mask plate covering the upper and lower sides of the bowl pen body.

This bowl pen element 3 is flat, as is evident in the figure, and the thickness is substantially equal to the thickness of the case 1, so that when it is inserted and stored in the case 1 like the mechanical pencil element 2, It is integrated with the case 1, and is comprised so that it may become a card-like form.

As mentioned above, although this invention was demonstrated about the composite writing mechanism which consists of a mechanical pencil element and a ball pen element, this invention is not limited to this, It can be comprised combining one or two or more of various writing elements arbitrarily. Of course.

Since the writing instrument of the present invention is so constructed that one or a plurality of writing elements flat as described above are housed in a corresponding cutout portion of a card case and can be freely pulled out and integrated into a card form as a whole, Practical effect that it is portable and is extremely convenient is effective.

Claims (3)

A card-type writing instrument characterized in that one flat or a plurality of writing elements are inserted in a corresponding cutout portion of a card-like case and can be freely pulled out to be integrated as a card. A card-type writing instrument as claimed in claim 1, wherein the writing element is a mechanical pencil element and / or a bowl pen element. A card-type writing instrument as claimed in claim 2, wherein an opening for supplying the core is provided at the top of the green portion of the sharp pencil element.
