Description

[0001] APPARATUS FOR TOUCH-PEN RECOGNIZING WRITING PRESSURE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a touch pen device, and more particularly, to a touch pen device capable of recognizing a pressure that is a force that a user presses a pen.

There has been proposed a technique of inputting a handwriting of a user by making a handwriting directly on a predetermined plane (a touch screen of a tablet) using a pen-shaped tool (e.g., a touch pen).

The inclusion of touch functionality in mobile devices has become a fundamental issue, and the application of digitizers is increasing.

The actual pen touch sensation appears as the line's depth, thickness, and texture, and the digitizer is evolving to a level that changes line thickness and tint when the user draws the line with the pen.

The stylus pen that can recognize the proposed pressure until the present time is an EMR stylus pen.

In the case of the stylus pen of the EMR system, the pressure is recognized by recognizing that the impedance of the coil disposed inside the pen changes due to the depression of the pen tip, thereby changing the output frequency.

However, in the case of the digitizer of the EMR scheme according to the related art, there is a disadvantage that the unit price is high, and an attempt is made to utilize the touch pen using the existing touch screen.

Typically, in order to vary the touch area according to the pressure of pressing the pen in the stylus pen of the touch type, it is difficult to change the contact area of the pen tip as much as the designer wants by simply forming the pen tip using a rubber material .

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above problems, and it is an object of the present invention to provide a touch-sensitive touch pen device capable of easily changing a pen tip according to a pressure, The purpose is to provide.

A touch-pen-type touch-pen device according to an embodiment of the present invention includes a pen-tip support rod that is disposed in a housing and a housing of a touch pen to change an area of the pen-tip contacting the touch screen in accordance with the pressure.

The pressure-sensitive-recognition-type touch pen device according to the present invention can be applied to a passive style stylus pen to provide a pressure-pressure recognition function at a low cost.

According to the present invention, the wedge-shaped pen tip supporting bar and the extending guide are changed in the fitting shape according to the pressing force, and as a result, by changing the area of the pen tip (conductive rubber), when the touch area with the touch screen is narrow, When the touch area with the screen is wide, it is recognized that a high pressure is applied, thereby providing an additional function.

The effects of the present invention are not limited to those mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the following description.

FIG. 2 is a side sectional view of a pressure-sensitive-recognition-type touch pen device according to the second embodiment of the present invention, and shows a state in which the area of the pen tip is relatively widened when the pressure is applied.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, advantages and features of the present invention and methods of achieving them will be apparent from the following detailed description of embodiments thereof taken in conjunction with the accompanying drawings.

The present invention may, however, be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, And advantages of the present invention are defined by the description of the claims.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. &Quot; comprises "and / or" comprising ", as used herein, unless the recited component, step, operation, and / Or added.

1 is a side sectional view of a touch-sensitive touch-pen device according to an embodiment of the present invention.

The present invention has been proposed in order to recognize a user's pressure, which is applied to a passive stylus pen which can be implemented at a low cost, unlike a conventional method of recognizing a pressure through impedance control such as a stylus pen.

1, a touch-sensitive touch pen device according to an embodiment of the present invention includes a housing 100 and a pen tip 400 disposed in the housing 100 and contacting the touch screen according to a user's pressure And a pen tip support rod 300 for changing the area.

At this time, the pen tip 400 is formed of conductive rubber, and it is preferable that an empty space is formed therein.

1, the pen tip support bar 300 is supported by a pen tip supporting spring 200 and pushed when a pressure is applied, thereby changing the contact surface of the pen tip 400, which is in contact with the touch screen, .

FIG. 2 is a side sectional view of the pressure-sensitive-recognition-type touch pen device according to the second embodiment of the present invention and a state in which the contact area of the pen tip 400 is relatively widened when the pressure is applied.

As shown in FIG. 2, the pen tip support bar 300 is formed in a wedge-like shape in which its cross section is gradually narrowed from the body to one end.

The pressure-sensitive-recognition-type touch pen device includes an extension guide 500 that wraps around one end of a wedge-shaped pen tip support rod 300.

2, the wedge-shaped pen tip supporting bar 300 is pushed up when the user presses the pen, and the inner angle of the one end of the pen tip supporting bar 300 is moved toward the center of the extending guide 500 The pen tip supporting bar 300 is pushed up by the pressure and the expanding guide 500 is unfolded like the umbrella is unfolded.

That is, when the pressure is applied, the extension guide 500 having a relatively wide angle of entry by the pen tip support rod 300 widens the contact area of the touch screen with the pen tip 400 (conductive rubber) which is in contact with the extension guide 500.

Accordingly, when the user presses the touch pen with a small pressure, the angle of entry of the expanding guide 500 becomes small. As a result, the contact area between the pen tip 400 and the touch screen is narrowed. When the user presses the touch pen with a large pressure, The entry angle of the guide 500 is greatly increased, resulting in a wider contact area between the pen tip 400 and the touch screen.

The touch screen can easily recognize the pressure of the user through the change in the touch area.

The embodiments of the present invention have been described above. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
