Description

The writing instrument having stylus pen function

The present invention relates to a writing instrument having a stylus pen function, which will be described in more detail by simply operating a function of a stylus pen for operating a touch screen of various portable devices and a pen for general writing by a single push button. The present invention relates to a writing instrument having a stylus pen function developed to be selectively used.

In the case of various portable multimedia devices including mobile phones and PDAs, the development speed of the past 10 years has recently been rapidly developed to be achieved in one year, and is gradually becoming multifunctional, large in size, and small in size.

In the past, a method of using a variety of electronic devices has been used by manipulating a keyboard or a keypad. However, as devices become smaller and thinner, it is difficult to have enough keypads for input.

For this reason, the touch screen, which was used for professional use in the past, has been applied to portable devices such as mobile phones, capacitive overlay, resistive overlay, infrared beam, and integrative methods. Among the various types of touch screens such as the tension strain method (Integral Strain Guage), the pressure resistive film method was mainly used in the early days, but the contact capacitive method is most recently used due to the inconvenience of use.

At first, however, a stylus pen or a touch pen was provided to facilitate the use of the touch screen, so that it could be easily hung like a cell phone decoration ring when needed. However, there was a high risk of loss and damage.

In addition, most users are using a finger to touch, but because of the touch area with a large finger, the wrong touch frequently used, there was a disadvantage that requires a significant concentration to accurately touch.

Hereinafter, the principle of operating in each mode according to each configuration of the present application will be described in more detail.

5 is a cross-sectional view showing a protruding state of the stylus pen according to an embodiment of the present invention, Figure 6 is a conceptual diagram showing a protruding principle of the stylus pen according to an embodiment of the present invention, first and first 2 guide step (156, 157) is a guide projection 161 of the push button 16 is to pass along the guide groove 155, but the second cam 162 of the lifting jig (2) is to prevent the passage. .

First, the stylus nib 334 and the ball pen nib 4 are in contact with the lower cap 14, so that the guide protrusion 161 of the push button 16 is the first inclined protrusion 152 and the third inclined. It is a state which entered the guide groove 155 formed between the protrusion 154.

When the push button 16 is pressed, the first cam 162 presses the second cam 23 to rotate the lifting jig 2 while descending along the inclined surface so that the second cam 23 rotates along the first inclined protrusion. After contact with the inclined surface of 152 is seated on the first guide step 156, when the push button 16, the push button 16, the guide projection 161 is the first inclined protrusion 152 and the second inclined It will rise along the guide groove 155 between the protrusions 153.

Therefore, the stylus nib operating unit 3 and the ball pen nib 4 protrude as a distance between the upper end of the guide groove 155 and the first guide step 156. .

At this time, the conceptual diagram of FIG. 6 is an unfolded structure of the upper cap 15.

7 is a cross-sectional view showing a protruding state of the ball pen nib according to an embodiment of the present invention, Figure 8 is a conceptual diagram showing the protruding principle of the ball pen nib according to an embodiment of the present invention, before the ball pen nib (4) is protruded The guide protrusion 161 is positioned between the first inclined protrusion 152 and the second inclined protrusion 153. When the push button 16 is pressed, the first cam 162 presses the second cam 23. The lifting jig 2 rotates while descending along the inclined surface so that the second cam 23 contacts the inclined surface of the second inclined protrusion 153, and is seated on the second guide step 157, and the push button 16 is pressed. When the push button 16 is a guide projection 161 is to rise along the guide groove 155 between the second inclined protrusion 153 and the third inclined protrusion 154.

Accordingly, the stylus nib actuating portion 3 protrudes as a distance between the upper end of the guide groove 155 and the second guide step 157, and the ball pen nib 4 protrudes further and exits the through hole 321.

Located between and the third inclined protrusion 154, when the push button 16 is pressed, the first cam 162 presses the second cam 23 to rotate the lifting jig 2 along the inclined surface while rotating. After the second cam 23 abuts the inclined surface of the third inclined protrusion 154, the guide protrusion 161 and the second cam 23 are disposed between the third inclined protrusion 154 and the first inclined protrusion 152. Along the guide groove 155 in the will be to go into the lower cap (14).

10 is a conceptual diagram showing the protruding principle of the stylus pen according to another embodiment of the present invention, Figure 11 is a conceptual diagram showing the protruding principle of the ball pen shim according to another embodiment of the present invention, Figure 12 is another aspect of the present invention As a conceptual diagram illustrating a principle of inserting a ballpoint pen core and a stylus pen according to an embodiment, the first inclined protrusion 152 extends downward from a surface adjacent to the third inclined protrusion 154 and the third inclined protrusion 154. An embodiment is characterized in that the rib 158 having the same height and inclined surface as is further formed.

According to the embodiment, when the guide protrusion 161 is positioned in the guide groove 155 between the third inclined protrusion 154 and the first inclined protrusion 152, the push button 16 is pressed to press the first cam 162. If the second cam 23 is lowered without rotating along the inclined surface when the second cam 23 is lowered, there is a risk of malfunction and was formed to reduce the misunderstanding due to the difference in the degree of pressing the push button 16.

In particular, when the guide protrusion 161 is positioned in the guide groove 155 between the second inclined protrusion 153 and the third inclined protrusion 154, the push button 16 is pressed to press the first cam 162. While lowering and rotating the second cam 23, the guide protrusion 161 is further rotated without being seated in the guide groove 155 between the third inclined protrusion 154 and the first inclined protrusion 152 by the rotational force. The guide protrusion 155 between the first inclined protrusion 152 and the second inclined protrusion 153 is placed in a state in which the guide protrusion is settled, that is, to prevent the use of the stylus pen rather than the storage state in the writing instrument state. will be.
