Description

[0001] The present invention relates to a ball pen for a capacitive touch pen,

The present invention can be used as a capacitive touch pen or as a ballpoint pen as a writing instrument. When the ballpoint pen tip is inserted, the pen tip can be used as a capacitive touch pen. When the ballpoint pen tip is taken out, Or a ballpoint pen.

A touch screen panel of an electronic device that can be controlled using a smart phone, a tablet, or other touch screen can be classified into a depressurizing type in which the lower and upper electrodes selectively touch or a change in the capacitance of the touched portion A capacitive touch screen which can be mass-produced and has a low manufacturing cost is mainly used.

This electrostatic capacity type is designed to be input with the finger of a human body and can read the changed position of the capacitance value by the minute current flowing to the human body when the end of the finger touches the touch panel. It is impossible to operate with a touch pen, and for the same reason, there is a problem that a nail or a ball pen or other writing instrument can not be inputted to the touch screen.

Recently, various types of touch pens have been proposed so that signals can be inputted to a capacitive touch screen such as a current flowing in the human body to the touch pen or static electricity is generated at the tip of the touch pen. However, There is a problem that the current is not transmitted properly or irregularly, so that the signal input is not sensitive and the feeling of use is low.

In addition, such a touch pen needs to be separately provided as a touch pen for inputting text or the like on a touch screen, which is inconvenient to carry.

Therefore, the present invention can be used as a touch pen of a capacitive type, and when necessary, a ball pen can be drawn out to be used as a ball pen, so that a touch pen and a ball pen can be used together.

In addition, in forming the touch pen and the ballpoint pen integrally, the touch pen and the ballpoint pen can be manufactured simply by improving the structure without significantly deforming the shape, and the touch pen or the ballpoint pen can be changed So that the use of the conventional touch pen and ballpoint pen can be used as it is.

To this end, in order to achieve a change in capacitance, a ball head capable of being touched by mixing a conductive material is integrally formed in a ballpoint pen which can be used as a writing instrument, and the ball point pen of the ballpoint pen is drawn out through the ball head The touch pen and the ballpoint pen are all provided in the same direction so that the touch pen and the ballpoint pen can be easily converted by the simple operation.

In addition, while the ball head is made of an elastic material, the ball head made of the elastic material is inserted into the cap of the ballpoint pen by inserting it into the cap of the ballpoint pen so that the ball head is flexibly moved, .

Therefore, according to the present invention, since the touch pen and the ballpoint pen are integrally formed and can be selectively used according to the convenience of the user, the two kinds of articles can be integrated into one article and carried, The ballpoint pen is formed in the same direction, and the function can be changed by one touch, and the conventional method can be used as it is without changing the use method, so that anyone can use the ballpoint pen conveniently.

In addition, since a through hole is formed in the ball head to penetrate the ballpoint pen, the ball can move more flexibly when used with the touch pen, so that the input can be made more precise and the feeling of use can be enhanced.

In addition, since the touch pen can be integrally formed without enlarging the structure of the ballpoint pen, it is easy to manufacture and the manufacturing cost can be reduced, which is very economical.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the ballpoint pen core 11 is housed in the pen body 10, and a touch on the touch screen panel is applied to the front cap 12 through which the ballpoint pen core 11 is put in and out. So that the ballpoint pen tip 11 penetrates through the ball head 20 while being assembled with the ball head 20 so that the ball pen tip 11 can be selected and used as a touch pen or a ballpoint pen depending on whether or not the ballpoint pen tip 11 is drawn.

At this time, the ball pen nib 11 is to have a restoring force by the elastic means 13, such as a spring, the structure in which the ball pen nib 11 is drawn out of the button 14 as shown in Figs. It is formed in a structure that is pulled out by one touch by pressing or by dividing the pen body 10 into an upper body 10a and a lower body 10b as shown in FIGS. 6 and 7 by a rotation of the upper body 10a. Withdrawal of the shim 11 can be made, such a structure can be produced in a variety of ways deformed in the range not limited by the object of the present invention, the ball pen nib 11 in and out of the structure All can be applied.

The ball head 20 also mixes electrical material, most preferably an electrolyte, to allow a change in capacitance on the surface of the touch screen panel when the ball head contacts the touch screen panel, It is desirable to make it possible.

Therefore, in order to use the touch pen, the ballpoint pen 11 is inserted into the ball pen 20 to expose the ball head 20 and can be used as a touch pen. When the ball pen is used as a ball pen, The touch pen or the ballpoint pen can be selectively used according to convenience of the user, so that the two kinds of articles can be integrated into one article and carried, which is good in portability. Further, The conversion structure of the touch pen and the ballpoint pen is very simple and can be easily used by anyone.

Preferably, the ball head 20 has a structure in which a head body 21 made of an elastic material and a core 22 made of a rigid body are used as the ball head 20, The core body 22 is fixed to the cap 12 of the pen body 10 so that the head body 21 is exposed to the outside of the cap 12 so that the touch operation can be performed. By forming the through holes 21a and 22a at the centers of the head body 21 and the core 22, the ballpoint pen core 11 penetrates the head body 21 and the core 22 constituting the ball head 20 So that it can be withdrawn.

The head body 21 and the core 22 are formed to be engaged with each other by engaging means 21b and 22b so as to be assembled with each other so that the outer peripheral surface of the head body 21 is engaged with the cap It is possible to prevent the head body 21 from being arbitrarily separated from the core 22 by assembling the head body 21 in close contact with the inner circumferential surface of the core body 12. [

At this time, since the core 22 is tightly fixed to the inner peripheral surface of the cap 12 of the pen body, the head body 21 and the core 22 can be more firmly assembled and prevented from falling out. It is preferable that the inclined surface 12a is formed on the inner peripheral surface of the cap 12 so that the core 22 is not inserted forward in the state of being fitted to the cap 12 but is supported by the elastic means 13 in the rear direction.

That is, if the diameter of the inner circumference of the cap 12 is inclined so as to become gradually smaller toward the other side of the portion to be coupled with the pen body 10, the core 22 is closely fixed to the inner circumferential surface while being inserted into the cap 12, 22 is formed at the back of the core member 22 so that the elastic means 13 such as a spring for fixing the ballpoint pen core 11 can be seated. So that it can be pushed and fixed to the front side of the cap 12.

At this time, if the outer peripheral surface of the core member 22 is formed to correspond to the inclined inclination of the inner surface of the cap 12, more rigid assembly can be performed.

8, when the step 12b is formed on the inner circumferential surface as shown in FIG. 8, the flange 22c of the core 22 is caught by the step 12b, The diameter of the inner circumferential surface of the cap 12 is different from the diameter of the portion where the outer circumferential surface of the head body 21 is located and the diameter of the portion where the outer circumferential surface of the core 22 is located, 22 are tightly fixed to the inside of the cap 12 and the inner circumferential surfaces of different diameters so that the head body 21 and the core material 22 are more firmly fixed. It is possible to prevent the head body 21 from being arbitrarily disengaged from the core 22 in the operation.

That is, even if the outer circumferential surface of the head body 21 is closely fixed to the inner circumferential surface of the inner circumferential surface of the cap 12 formed by the step 12b with a relatively small diameter, The core member 22 on the rear side can be prevented from being pulled out of the flange portion 22c of the core member 22 on the inner circumferential surface where the diameter is relatively large by the step 12b, The outer peripheral surface of the ball head 20 is tightly fixed to prevent the ball head 20 from flowing.

When a knurling unit (not shown) having a plurality of reinforcing pieces formed to correspond to each other is formed on the inner circumferential surface of the cap 12 and an outer circumferential surface of the core 22, And the ball head 20 can be made more rigid so as not to be arbitrarily rotated.

Meanwhile, the ball head 20 is formed with curved portions 21d and 22d on the outside of the head 21 and the through holes 21a and 22a of the core material 22 so that the ball head 20 may have a cap 12. When exposed to the outside of the curved portion is exposed so that the touch of the touch screen can be rubbed in a large area, such that the curved portion 21d of the head 21 is spaced apart from the curved portion 22d of the core material 22 If it is to be formed so that the movement of the head 21 is more flexible to be able to increase the touch recognition rate.

That is, when the head body 21 rubs against the touch screen panel and moves, the head body 21 is flexibly moved so that a relatively large surface is brought into contact with the touch screen panel. Therefore, The material increases the degree of reactivity with the electrode patterns of the touch screen panel, so that the capacitance change can be more easily brought up, so that the touch recognition rate can be increased, the input can be made more precise, and the feeling of touch feeling can be increased.
