Description

[Detailed description of the invention] Conventionally, a front body and a rear body made of hard synthetic resin have a U-shaped recess in the middle part of each inner surface, a groove at the tip, and a semi-cylindrical protrusion at the rear end. The front body and the rear body are combined in a so-called belly-to-belly state, with a flat hollow part open on both sides at the middle part, and a two-pronged part for one line of core at the tip, and a two-pronged part for a single line person at the rear end. Shape each cylindrical insertion part, and then remove and fit a hard synthetic resin cap body with a small amount of elasticity into the cylindrical insertion part at the rear end, and glue the base ends of the two prongs. A shaft body is formed by pasting adhesives on each other, and a large number of color cores of each color are inserted into the above-mentioned flat hollow part in a horizontally arranged state, and one of the color cores is inserted between both legs of the one-pronged part. Book on both legs 13.13'
A writing instrument is known in which the writing instrument is held in such a way that it can be inserted and removed using the elasticity of the writing instrument. Since it is simply attached with adhesive, if a thick color core is strongly inserted into the fork of the garlic, the pressure from the inside will force the attached part to separate, causing the front and rear surfaces to separate. There was a risk that the two would separate from each other, causing not only the diagonal fork and the diagonal core to lose their single-stop function, but also to cause the shaft to collapse.

The purpose of the present invention is to eliminate such defects, and the illustrated embodiment includes a front body 1 made of a colorless transparent hard synthetic resin material and a rear body 2 made of a transparent hard synthetic resin material. A U-shaped recess 4, 4' is provided at the intermediate part of the inner surface of the cylindrical member, and semi-cylindrical protruding rods 5.5', 6.6 are provided at the tip 3 and rear end.
', and the front body 1 and the rear body 2 are inseparably joined together with an adhesive (not shown) in a so-called face-to-face state, and a flat hollow part 7 which is open on both sides is formed in the middle part. A cylindrical insertion part 8, 8' is formed at each end, and sponge seams 1 to 15 are stretched on the rear wall surface of this flat hollow part 5,
(The cylindrical insertion parts 8 and 8' at both front and rear ends are colored with a little elasticity. Made of transparent hard synthetic resin material.) ) is irremovably attached to form the shaft body 3, and a downwardly directed prong 10 is attached to the top end of the f-side cap body 9', and an ornament that can be clipped onto a pocket of clothes or the like is attached to the side surface of the upper cap body 9. Body] Each clip 11 with 6-・
Furthermore, a large number of colored cores 12 of each color are inserted into the flat hollow part 7 in a sideways arrangement without sliding, and the above-mentioned One color core 14 similar to the color core 12 is attached to both legs 13.13'
It is held so that it can be inserted and removed by its elasticity.

In addition, 17 in the figure is a transparent soft synthetic resin cap;
8.18' indicates the entry groove.

Since the present invention is as described in Narukami, it is extremely convenient because it can be used as a colored pencil in multiple colors by arbitrarily replacing the colored core attached to the tip of the shaft and the colored core of each color loaded in the spare part. Of course, in the present invention, semi-cylindrical projecting rods 5.5' and 6.6 are provided at the tips and rear ends of the front body 1 and the rear body 2, and these front body 1, The rear body 2 is combined in a so-called face-to-face state, and cylindrical insertion parts 8 and 8' are formed at the tip and rear ends, respectively, and the cylindrical insertion parts 8 and 8' at both front and rear ends are provided with a small amount of elasticity. Both upper and lower cap bodies 9, 9' made of a hard synthetic resin material are irremovably attached to form a shaft body 3, and a three-pronged part 10 is provided on the lower cap part 9'.
Since the color core 14 and the color core 12 are sandwiched in such a way that they can be inserted and removed, even if a thick color core is strongly inserted into the forked portion 10, the color core 14 and the color core 12 will not be able to be inserted or removed before forming the shaft body 3 as in the above-mentioned known method. , the rear surface portions 1 do not act as forces that cause them to separate from each other, thereby avoiding a situation where the shaft body 3 is deformed, thereby ensuring that the above-mentioned object of the present invention is achieved. There is a potential effect.
