Abstract

(57) [Summary] (Correction) [Purpose] A ballpoint pen that can easily write characters of different colors with a very simple operation, and has a simple structure. [Structure] A plurality of ball-shaped pen cores 2 and 3 having different colors of ink contained therein are projected extremely close to each other from one end of one ball-point pen shaft 1. To use it, you can write a character of another color by simply grasping the pen shaft 1 with your hand and reversing the shaft 1 by 180 ° while holding the shaft as needed during drawing. [Effect] (1) It is possible to instantly write characters of different colors with one ballpoint pen. (2) The operation is extremely easy. (3) The structure is simple.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ball-point pen for writing characters of different colors with one ball-point pen as shown in the drawing. As shown in the drawing, an ink containing A color (for example, black) ink is incorporated. The built-in ink from the tube (4) passes through the drawing ball holding cylinder (5) to reach the surface of the drawing ball (2), and the drawing ball (2) can draw an A color character. The B color (for example, red) ink is built into the ink tube (6), and the ink reaches the drawing ball (3) at the tip to draw the B color character. As shown in the figure, the drawing balls (2) and (3) should be close to each other as much as possible so that the ink on the surface of (2) and the ink on the surface of (3) do not mix. Etc. (13) and bundle it with a ballpoint pen shaft ( (2) and (3) are aligned from one end of the ball-point pen shaft (1) of (3) and are projected to the outside of the shaft (1). The core is fixed to the shaft (1). The wick (Fig. 4) is passed through the wick fixture (Fig. 5) and the fixture (Fig. 5) is inserted into the ball-pen shaft (1). It is the point that the drawing balls (2) and (3) with different numbers are arranged very close to each other and juxtaposed outward from one end of the ball-point pen shaft in the same direction, but like the conventional ball-point pen core (Fig. 2). When two of them are arranged side by side, the ink tube is thick, so this hinders the ink ball from coming close to it. The ink storage capacity is reduced if the ink tube is made thinner. Bend (5 ') and make the lead (Fig. 3) face the usual lead (Fig. 2). Hold the ball with the ball-shaped pen (2), (3) brought close to each other and inserted into the ball-point pen shaft (1) so that the ball portion adjacent to one end of the shaft (1) protrudes off the shaft. Since the tube (5 ') is in contact with the holding tube (5) at an angle, the drawing balls (2) and (3) are very close to each other. The ball-point pen core (Fig. 3) in which the drawing ball holding tube (5') is bent. It is also possible to face two drawing balls. Also, as shown in FIG. 6, the drawing balls (9) and (10) held by the drawing ball holding cylinders (7) and (8) are not bent, and the drawing balls are held close to each other. (12) may be bent Further, as shown in FIG. 8 and FIG. 9, a trapezoidal ball-point pen head is directly provided with a hole (15) corresponding to the drawing ball holding cylinder of a conventional ball-point pen, and the hole (16) is also slanted. In addition, the end of the hole (15) and the hole (16) should be made close to the portion where the drawing ball is to be inserted. The mounting part (17) is directly drilled into the ink tube mounting part (18) obliquely, and the drawing balls (19) and (20) and the ink tubes (21) and (22) are mounted on the ball pen. May be attached to one end of the shaft (1 ') is a pen shaft. The present invention is applicable to 3 different colored drawing balls as well as 3 different colored drawing balls. The position of (3) may be combined so as to be slightly shifted back and forth with respect to the axial direction. (11) is an ink tube of A color and (12) is an ink tube of B color. ) Is an A color ink tube and (22) is a B color ink tube The present invention has the following effects (1) A and B bicolor drawing balls from one end of the ballpoint pen shaft (1) Since it is protruding, you can rotate it 180 ° while holding the shaft (1) and perform other operations. It is very convenient for students who frequently change writing instruments such as black and red when studying because they can draw and use the two colors A and B immediately without doing (2) A, B The two-colored balls (2) and (3) are proximate to each other and project from one end of the shaft (1) in the same direction, so that it looks like a one-color ballpoint pen and has a good appearance. It feels and is comfortable to use one ball-point pen from (4) Simple structure
