Description

[0001] The present invention relates to a multi-contact pen core and an electronic pen including the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic pen, and more particularly to a multi-contact type pen pen and an electronic pen including the pen tip.

The touch of a keyboard or an icon displayed on a touch screen of various terminals uses a user's hand. However, there is a problem in that malfunctions such as touching the peripheral points other than the point to be touched or touching the position to be touched by the user, but touching the adjacent portion of the touched position are recognized first, .

An electronic pen is used to solve this problem. 1 is a view for explaining the operation principle of an electronic pen operating in an electromagnetic induction manner.

1 (a), a coil drive driver 20 and a loop coil 30 are shown, and an electronic pen 100 is shown in which a resonance circuit composed of a capacitor and an inductor is mounted on a substrate.

When the coil drive driver 20 is provided with a switching pattern having a predetermined frequency (that is, a resonant frequency of a resonant circuit of the electronic pen) under the control of, for example, an MCU (not shown) of the tablet, To the loop coil (30). The loop coil 30 has a predetermined inductance and emits an induced electromagnetic force (external electromagnetic force 1) by an input AC voltage.

On the other hand, in the resonance circuit of the electronic pen 100, an induced current is generated by resonance by the external electromagnetic force emitted, and the generated induced current is stored in the inductor and the capacitor. When the emission of the external electromagnetic force is stopped, the resonance circuit resonates by self-stored energy (induced current) to emit an induced electromagnetic force (acting electromagnetic force 2).

Accordingly, in the pen sensing area A of the tablet, the inductive electromagnetic force of the electronic pen 100 is sensed, the coordinates of the point where the sensed induced electromagnetic force is greatest (electronic pen sensing position) is measured, It is regarded that the user intends to input an operation using the electronic pen 100.

2 shows an example of measured values of a sensor by electromagnetic field distribution emitted from the electronic pen 100 when the electronic pen 100 is tilted on the tablet, The position of the contact line A on which the electronic pen 100 touches and the position of the display line B displayed on the tablet are shown.

Referring to FIGS. 2 and 3, the user actually uses the electronic pen 100 at an inclined angle with respect to the tablet 200. When the electronic pen 100 is inclined to the tablet 200, the position of the induced electromagnetic force generated in the resonance circuit inside the electronic pen 100 is generated in proximity to the tablet 200. The position of the center axis C of the sensor measured due to the electromagnetic field M generated by the electronic pen 100 is shifted from the contact position A of the electronic pen 100 to the position The position of the pen 100 is shifted away from the direction in which the pen 100 is tilted.

2, the center axis C of the distribution of the electromagnetic field (M) measured by the sensor contacts the point A of the tablet 200 as B And an indication according to the contact of the stylus 102 of the electronic pen 100 is displayed on the point B. As shown in Fig. 3, the display line B is displayed on the tablet 200 near the actual contact line A of the electronic pen 100. There arises a problem that an icon located near the desired icon is executed instead of the icon of the desired position based on this operation method.

When a user writes or draws a picture using the electronic pen 100, the position (contact line A) where the pen tip 102 of the electronic pen 100 touches the tablet 200 and the position The position (display line B) displayed on the display unit 200 is different, so that it is difficult to select the position to be displayed, and the display is visually confused. In addition, as shown in FIG. 3, the error e between the contact line A and the display line B may cause the reliability of contact with the electronic pen 100 to deteriorate.

Therefore, a mechanical or electronic supplementary measure for eliminating the inconsistency between the position at which the pen tip 102 of the electronic pen 100 is brought into contact with the tablet 200 and the position at which the pen tip 102 is displayed on the tablet 200 is required, A method for minimizing noise due to the contact of the pen tip 102 and the tablet 200 when the electronic pen 100 is used should be also taken into consideration. In addition, the degree of tilting of the writing instrument differs for each person at the time of using the writing instrument, so that the error between the contact line A and the display line B may be different or the pen nib 102 may not be contacted .
