It relates to a mini ballpoint pen characterized in that the.

In general, a ballpoint pen widely used is composed of a cylindrical body and a ballpoint pen inserted into the body. However, the ball pen nib may be selectively withdrawn or withdrawn from the body, or the ball pen nib protruded from the body may be accommodated as a cap in order to prevent the clothes, etc., from being discarded by the ink contained in the ball pen nib when carrying the ball pen. . Among them, as a method for selectively drawing and withdrawing the ball pen nib from the body, a separate button cap was generally used.

A commonly used button cap has a locking piece having its own elasticity on one side, and a locking groove on which the locking piece of the button cap is fixed is formed on one side of the body. When the button cap is pressed, the locking piece of the button cap is caught in the locking groove formed in the body and at the same time the ball pen core is withdrawn from the body. When the locking piece of the button cap is removed from the locking groove, the button is pressed by the elastic force of the spring mounted on the ball pen core. The cap and the ball pen nib rise at once, and the ball pen nibs are drawn into the body.

In the case of a ballpoint pen having such a configuration, at least the length of the ballpoint pen is settled at the intersection of the thumb and index finger when the ballpoint pen is held by using the thumb and the index finger for smooth writing of the user. (90 to 130 mm), and a ballpoint pen having such a length has a problem in that it is inconvenient to carry in a pocket or the like, and has a problem that a button cap must be pressed for withdrawal and withdrawal of a ballpoint pen shim.

Meanwhile, various ballpoint pens have been proposed to improve the portability of the ballpoint pen. Among them, the Korean Utility Model Publication No. 163332 has a ballpoint pen body and a case and a ballpoint pen lid, wherein the outer surface of the ballpoint pen is provided with an anti-slip uneven portion, The bottom of the ballpoint pen is attached to the leaf spring is fixed in the ballpoint pen cap, the portable accessory ultra mini ballpoint pen with a length of 3 to 5 times the cross-sectional diameter of the ballpoint pen cylinder is proposed, In addition, there is a separate plate spring for fixing the ball pen body to the lid, which is cumbersome to manufacture and assemble. Also, the ball pen lid is configured to accommodate a part of the ball pen body, which inevitably lengthens the length of the ball pen, thereby greatly increasing portability. There is a problem that cannot be improved.

The present invention for solving such a problem can greatly improve the portability by reducing the length of the ballpoint pen when carrying, the user can smoothly grip the ballpoint pen by lengthening the length of the ballpoint pen when writing, It is an object of the present invention to provide a mini ballpoint pen capable of withdrawing and withdrawing a ballpoint pen core from a ballpoint pen body without manipulation.
