Writing implement for drawing straight underline

Abstract

The present invention relates to a writing implement for drawing a straight underline. The writing implement for drawing the straight underline according to the present invention comprises: a pipe-shaped upper body part which has a space for a writing implement core for drawing a line formed on the inside thereof, which has an entrance formed on the upper surface thereof and which has a blocked lower surface; a lower body part which is stretched in the up and down direction in such a manner that the upper end of the lower body part is coupled with the lower end of the upper body part and; a main writing implement core which is installed at the lower body part so that the lower end of the main writing implement core is put on paper, thereby enabling writing; a writing implement core for drawing a line, which is inserted into the space for the writing implement core for drawing a line, which is stretched in the up and down direction, of which the lower end is in contact with the bottom of the upper body part and which has a writing tip formed in the upper end thereof to be put on paper, thereby enabling writing; a cap part which has a writing tip hole formed on the upper surface thereof, which has a pipe shape which the writing implement core for drawing a line passes through, and which is installed at the upper body part so that a portion of the cap part is inserted, through the entrance, into the upper section of the space for the writing implement core for drawing a line and the level of insertion into the space for the writing implement core for drawing a line can be controlled; and a pair of guide wheels which are rotatably coupled, in parallel to each other, to the upper outer surface of the cap part which protrudes toward the upper side of the upper body part, wherein if the cap part is inserted, at a certain depth, into the space for the writing implement core for drawing a line, the writing tip of a ball pen core for drawing a line comes out to the outside of the cap part at a certain depth and then if the guide wheels are put on paper and move in a straight line direction, the writing tip of the ball pen core for drawing a line also moves while being in contact with paper to thus enable an underline to be drawn. In addition, the writing implement for drawing the straight underline according to the present invention comprises: a pipe-shaped upper body part which has a space for a writing implement core for drawing a line formed on the inside thereof, which has an entrance formed on the upper surface thereof and which has a blocked lower surface; a lower body part which is stretched in the up and down direction in such a manner that the upper end of the lower body part is coupled with the lower end of the upper body part and; a writing implement core for drawing a line, which is inserted into the space for the writing implement core for drawing a line, which is stretched in the up and down direction, which is installed so that the lower end thereof is positioned apart from the bottom of the upper body part, and which has a writing tip formed at the upper end thereof to be put on paper, thereby enabling writing; a cap part which has a writing tip hole formed on the upper surface thereof, which has a pipe shape which the writing implement core for drawing a line passes through, and which is installed so that a portion of the cap part is inserted, through the entrance, into the upper section of the space for the writing implement core for drawing a line and the level of insertion into the space for the writing implement core for drawing a line can be controlled; and a pair of guide wheels which are rotatably coupled, in parallel to each other, to the upper outer surface of the cap part which protrudes toward the upper side of the upper body part, wherein if the cap part is inserted, at a certain depth, into the space for the writing implement core for drawing a line, the writing tip of a ball pen core for drawing a line comes out to the outside of the cap part and then if the guide wheels are put on paper and move in a straight line direction, the writing tip of the ball pen core for drawing a line also moves while being in contact with paper to thus enable an underline to be drawn.

Description

technical field [0001] The present invention relates to a writing implement capable of drawing straight underlines, and more particularly relates to the following writing implements capable of drawing straight underlines: since an integrated device with a ballpoint pen is provided, underlines can be drawn conveniently without a ruler, and excellent Processability, marketability, aesthetics, etc. Background technique [0002] In the past, when drawing lines, only a ruler could be used to draw or other devices could be combined with a pen to draw lines. [0003] According to the conventional method as mentioned above, if you want to draw a line during the writing process, you need to use a ruler to draw a line or combine other devices with a pen to draw a line, and then continue to write after disassembling other devices, so there is no way to concentrate on writing. Learning takes a lot of time, and the ruler cannot be seen clearly due to the combined props when underlining....
