Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the exemplary embodiments of the present invention, descriptions of techniques which are well known in the art and are not directly related to the present invention will be omitted. This is to omit the unnecessary description so as to convey the key of the present invention more clearly without fading.

The touch sensing panel applied to the embodiment of the present invention is a device having a touch sensing sensor capable of inputting information using a user's finger or the electronic pen 100. [ In general, the touch sensor is divided into a resistive membrane type (pressure sensitive type) and a capacitive type.

Resistive film type (pressure sensitive type) is a multilayer film on a liquid crystal. Outer side is a smooth and scratch resistant film. A transparent conductive film for sensing input (two thin and transparent substrates that are electrically conductive overlap each other ). Detects changes in current and resistance caused by two transparent conductive films coming into contact with each other, and discriminates the input.

The electrostatic capacity is a method of using the static electricity in our body. The liquid crystal glass of the electrostatic touch-sensitive panel is coated with an electrically conductive compound, so electricity continues to flow. When a finger touches the screen, electrons flowing on the liquid crystal are attracted to the contact point. And detects the input. Therefore, touch input is possible even if you touch the screen slightly, and multi-touch is supported.

FIG. 2 is a perspective view of the electronic pen 100 shown in FIG. 1 mounted on a finger, and FIG. 3 is a perspective view of the electronic pen 100 shown in FIG. FIG. 4 is a front view of the electronic pen 100 shown in FIG. 3, FIG. 5 is a side view of the electronic pen 100 shown in FIG. 1, and FIG. Which is a perspective view schematically showing the structure of the battery 200 according to the present invention.

In the embodiment of the present invention, the electronic pen 100 is shown as a bar shape having a rectangular cross section, but the shape of the electronic pen 100 is not limited to this, and may be a square shape or a shape depending on the overall shape of the electronic pen 100 .

1 to 5, an electronic pen 100 used in a touch sensing panel according to an exemplary embodiment of the present invention includes a pen tip 110, a body 130, a fixing member 140, And a mode button 160, as shown in FIG.

The pen nib 110 is provided at the end of the electronic pen 100 and has a pointed shape for precise contact with the touch sensing panel. The pen tip 110 is made of a conductive material, and the outer circumferential surface of the body 130 other than the portion contacting the touch sensing panel is covered with an insulator.

When a predetermined position of the touch sensing panel is touched by the pen tip 110, the touch sensing panel senses the position of the touch operated panel and then executes a program corresponding to the touch position. For example, when the pen tip 110 performs a touch operation on the erasing area displayed on the touch sensing panel, the erasing mode program corresponding to the touch position is set in the touch sensing panel.

The touch hardness of the pen nib 110 is implemented as hard or soft as required. Preferably, the pen tip 110 having a soft hardness is used for the resistive membrane type (decompression type), and the pen tip 110 having a strong hardness is used for the electrostatic capacitance type. The pen tip 110 may have a different shape depending on the electrostatic capacity type or resistive type (depressurized type). In addition, the pen tip 110 can be replaced when the tip of the pen tip 110 becomes worn or worn out after several times of use.

The fixing member 140 is formed at a predetermined position of the body 130 away from the pen point 110. [ One end of the fixing member 140 is coupled to the body 130 in a whitish manner, and the other end of the fixing member 140 is vertically angled along the fixed hinge axis. Specifically, one end is fixed to the body 130 and the other end is formed to open outward from the body 130 about a fixed point.

That is, the fixing member 140 is formed on a part of the body 130 to accommodate the fingers and to support and hold the fingertips. The fixing member 140 is mounted on the outer peripheral surface of the body 130 And is rotatably fixed at a predetermined angle along the hinge axis so as to be inserted into the receiving groove 141. The receiving groove 141 is formed at a predetermined position on the body 130 facing the receiving groove 141, A cap 143 for supporting the fingertip on the body 130 is formed to prevent the fingertip from being pushed in the vertical direction.

A through hole is formed in each of the body 130 and the cap 143, and a hinge shaft is inserted into the through hole, thereby coupling the body 130 and the cap 143.

The shape of the cap 143 for storing the electronic pen 100 in the portable terminal 200 is set to be the same as the shape of the bottom surface of the receiving groove 141 and the shape of the bottom surface of the receiving groove 141, It is preferable that the above-

For example, as shown in Fig. 3 (a), the contact surface of the fingertip is convexly curved, the fingertip contacting surface is concavely curved inward as shown in Fig. 3 (b) (c), the surface of the fingertip contacting the fingertip may be continuously convexly curved, or may be variously shaped according to a user's demand, such as a shape in which the cross section of the fixing member 140 is rectangular, though not shown.

When the cap 143 is opened in the body 130 around the axis of the white paper and the fingertip is received in the receiving groove 141 and the fingertip is supported in the vertical direction by the cap 143, The finger is prevented from slipping in the vertical direction.

One end of the fixing member 140 is fixed to the body 130, so that the cap 143 is fixed to the body 130.

When the cap 143 is rotated in the outer direction of the body 130 about the axis of the white paper, one end of the fixing member 140 is separated from the body 130 and separated, and when the cap 143 returns to the body 130, And is housed in the receiving groove 141. That is, when the cap 143 is opened outward from the body 130, a space having the same shape according to the shape of the fixing member 140 is formed on the body 130. The space is used as a space in which a finger can be fixed as shown in Fig. The user can fix the fingers in the space and fix the fingertips by the cap 143, so that the user can draw more reliably.

The release preventing member 150 is formed at a position away from the fixing member 140, that is, at a position where it can cover the second node of the user's finger.

A predetermined length of groove is formed in the body 130 along the outer circumference of the position for fixing the finger, and the separation preventing member 150 is wound on the groove (see FIG. 1). Preferably, as shown in FIG. 4, the release preventing member 150 is wound only up to the same height as the outer circumferential surface of the body 130 and does not protrude to the outside.

Since the one end of the release preventing member 150 is fixed to the body 130 and the other end of the release preventing member 150 is wound around the body 130, the finger is held by the other end to fix the finger to the body 130. 4, one end of the release preventing member 150 is fixed to the body 130 and the other end is wound around the body 130 in a state where the other end is not fixed. Before using the electronic pen 100, the user loosens the unfixed portion of the release preventing member 150 and winds it around the user's finger.

The release preventing member 150 may be made of a rubber, a synthetic resin film, or a similar material, which is wound around the body 130.

6 is a block diagram showing the configuration of the electronic pen 100. As shown in Fig. 6, the electronic pen 100 generates a control signal for executing a mode command requested by a plurality of mode buttons 160 and mode buttons 160 for switching an operation mode, And a control unit 180 for transmitting the program to a main body having a built-in program for executing the program.

That is, the electronic pen 100 of the present invention may further include a mode button 160 for controlling the operation of the electronic pen 100 at a predetermined position of the body 130. The mode button 160 can be variously implemented by a two-contact sliding method or a one-contact sliding operation method in which the mode button 160 is slid up and down and changes the contact state. In the embodiment of the present invention, .

Here, one contact at the upper end of the mode button 160 is a mode for inputting information into the electronic pen 100, and two contacts at the lower end are modes for erasing the input information with the electronic pen 100 or the user's finger. For example, when the mode button 160 is positioned at one contact, information such as text, pictures, and the like can be input by contacting the pen tip 110 with the touch sensing panel. In addition, when the mode button 160 is positioned at two contacts, the user can touch the finger on the touch sensing panel to erase the input information.

That is, the controller 180 transmits a clear mode command to the controller 180 when the slide mode is selected by the two contact points of the erase mode button 160. The controller 180 controls the controller 180 in accordance with the received erase mode command, And transmits it to the main body.

For example, the erase mode button 160 selects one of the eraser mode 1 for erasing the information input by the electronic pen with a finger and the eraser mode 2 for erasing the information input by the electronic pen using the electronic pen And generates a mode command selected from the eraser mode 1 and the eraser mode 2, and transmits the generated mode command to the controller 180.

The control unit 180 generates a control signal for executing the predetermined mode, and transmits the generated control signal to the pre-stored main body of the program for executing the corresponding mode.

Accordingly, it is possible to erase the input information displayed on the screen by touching the finger on the touch sensing panel. Therefore, the user can quickly erase the inputted information without fingering through the complicated menu level.

The electronic pen 100 according to the embodiment of the present invention is housed in the portable terminal 200 having a storage space, thereby enhancing the retractability and portability. The electronic pen 100 is stored in the portable terminal 200 in a state where the fixing member 140 is attached to the body 130 and the separation preventing member 150 is wrapped around the body 130. [ When the portable terminal 200 detects that the electronic pen 100 is housed, the use of the electronic pen 100 is inactivated. On the contrary, when the electronic pen 100 is separated from the portable terminal 200, the use of the electronic pen 100 is activated and the user can touch the touch sensing panel of the portable terminal 200 through the touch.

Although the thickness of the electronic pen 100 is reduced in order to improve portability, the electronic pen 100 is provided with the fixing member 140 and the separation preventing member 150 so that the electronic pen 100 can be stored in various portable devices. And has an effect that can be gripped and used. In addition, the electronic pen 100 having the above-described configuration provides an optimum grip feeling, and stable drawing is possible even for long-time use.
