[0001] SWITCH APPARATUS FOR STYLUS PEN [0002]

The present invention relates to a switch device of a stylus pen in which a switch section is constituted so as to turn on / off power of a battery section as the pen cover section of the stylus pen with a built-in battery section is detached from the pen.

2. Description of the Related Art Generally, a portable communication apparatus is composed of a PDA, a PMP, an MP3 player, a mobile communication terminal, and the like.

As the portable communication apparatus has been miniaturized, a touch panel method has been adopted so that a user can input or select information more conveniently in place of a conventional key button input method. A method of inputting or selecting information directly to a computer and an interface through the panel, wherein if there is a touch of a stylus pen having a human hand or a tip at a specific position of the panel, . The function corresponding to the coordinate value is executed by the software through the coordinate value. Therefore, the touch panel provides a function as an information display unit and a function as an input unit.

The touch panel is largely divided into an electrostatic capacity type, a resistive type, an ultrasonic type, and an infrared type according to the principle of operation. Among them, the capacitive type and the resistive type are widely used. In recent years, the electrostatic capacitance type having superior characteristics in terms of durability and transmittance has attracted attention as compared with the resistance film type.

The resistive touch panel includes a film-shaped upper substrate and a lower substrate facing the upper substrate. An upper transparent conductive film is applied to a lower surface of the upper substrate, and an upper electrode is provided on both edge sides. A lower transparent conductive film is formed on an upper surface of the lower substrate and a lower electrode is formed in a direction perpendicular to the upper electrode on both edge sides of the lower substrate. And the upper and lower electrodes are integrally formed from one end of the upper and lower electrodes, and the upper and lower electrodes are assembled on one side of the upper and lower substrates to form a flexible printed circuit board (FPCB), and the flexible circuit is electrically connected Power is applied.

When the upper substrate is brought into contact with the stylus pen or the nail of the finger, the upper substrate and the lower substrate are brought into contact with each other due to the pressure of the touched portion, .

In the capacitance type touch panel, a capacitance sensing pattern made of ITO is formed on the lower surface of the transparent film. The electrostatic capacitance sensing patterns are arranged in a plurality of locations to recognize the positions of the touch points. Each of the electrostatic capacitance sensing patterns is electrically insulated from each other and is connected to the electrostatic capacitance sensor via a capacitive electrode line. The capacitive electrode line is covered and protected by the protective film.

When a touch is made to the transparent film, the capacitance sensor calculates the XY touch coordinates through a change in the capacitance inputted through the plurality of capacitance detection patterns.

However, in such a conventional capacitive touch panel, since the touch coordinates can be recognized only when a change in capacitance is caused by a plurality of capacitive sensing patterns provided on the lower surface of the transparent film, When a stylus pen or a user's fingernail with a sharp tip is used, there is almost no change in capacitance when touching a small area, so that the touch can not be recognized.

In order to solve such a problem, a battery unit is built in a stylus pen having a tip to generate an electrical signal so that an electrical signal generated from the pen can be detected when the touch panel is in contact with the electrostatic capacity type touch panel. However, The battery unit is built in for the generation of an electrical signal. However, since all the pens are small, the battery unit must be made compact so that the small battery unit can not be used for a long time because the amount of power is very small.

The pen is provided with a switch for turning on / off the power. However, when the user does not turn off the switch after use, the pen is in an ON state, But also has a disadvantage of power consumption.

Thus, the pen needs to be operated by the user to turn on / off the power separately.

Therefore, the user can turn on / off the power of the battery without separately turning on / off the user in the stylus pen with the built-in battery, (ON) only when the pen is used and turned OFF when not in use.
