July 31, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventor Heo, Joo Won (Gumi-shi, KR), filed on January 8, 2013, was made available online on July 17, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to GT Telecom Co., Ltd.

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to a touch pen for a portable phone having a gender unit, and more particularly to a touch pen for a portable terminal configured in such a manner that the touch pen used as a stylus pen for operating a touch screen of a portable terminal, such as a smart phone, is provided with a gender unit for use in interconnecting an external cable or an external device with the portable terminal, thereby providing convenience in use.

"In general, the term, portable terminal, is used to refer to a portable electronic device, such as a portable phone, a portable computer, a PDA, an electronic scheduler, a digital camera, an MP3 player, or a PMP. The use of such portable terminals has been gradually increased, and is now popularized to such an extent that the portable terminals become necessities of life. Recently, due to rapid supply of smart phones, the screens of the portable terminals are becoming larger and larger in order to increase the utilization of the portable terminals.

"Referring to a portable phone, which is represented by a smart phone which is most universally used among these portable terminals, an internal circuit is configured for an interface for communication between the portable phone and the outside in which the internal circuit may be varied according to the maker and type of the portable phone. In addition, a plurality of connectors are formed on a side of a case of the portable phone to interconnect the internal circuit and the external interface, thereby enabling an interfacing with the outside by inserting an external communication cable or a charge cable into to any of the connectors to be connected therewith.

"In general, a gender for a portable terminal is a connector that has a pin structure in order to allow a pin connector of a terminal, such as a smart phone, to be mated with a USB connector popularized for interconnection between different types of devices or for electric charging to a personal computer or the like, thereby serving as a connection medium that allows a charger to be used or to be connected to a USB. Typically, the gender may be classified as an accessory for use in charging a portable phone and data transmission.

"Recently, due to the progress of semiconductor terminologies and electronic terminologies, the supply of smart phones with a touch panel to which a touch screen type is adopted is expanded. Such a touch panel is configured in such manner that an operator can operate a system of the portable terminal by touching a transparent plate provided on the top of the touch screen (display screen) using fingers or a touch pen.

"Such a touch panel is classified into a resistive type, a capacitive type, an infrared type, and an ultrasonic type. Recently used the most is a capacitive coupling type touch panel which is configured such that when a user (human) touches the touch screen, an electrostatic capacity is formed to make micro-current flow through the corresponding condenser. The touch position is detected by detecting the change of the micro-current, and then the corresponding operation is processed.

"In the prior art, genders have also been developed and used which are configured to interconnect a portable terminal and an external device or to maintain a condition of being connected to a portable terminal in order to charge the portable terminal. A gender applied to a conventional portable phone as illustrated FIG. 14 and included in a previous patent application in the name of the present assignee will be described with reference to the drawing.

"A gender 1 for a conventional portable terminal includes a male connector 4 configured to be insertion-coupled to a pin connector 3 provided in a portable terminal 2, and a gender body 8 provided with a female connector 7 configured to be connectable with an external connector 6 of a common charger or a data communication cable.

"The gender body 8 is configured to be mechanically inserted into and fixed to the inside of a gender cap 10 to be capable of being removed by force, in which the gender cap 10 is connected to the portable terminal 2 via a string 9.

"A touch pen for operating the touch screen of the portable terminal takes a form to be stored in a reception recess provided on the portable terminal or a case for protecting or receiving the portable terminal, or in a user's pocket when it is not used.

"In the prior art as described above, when it is desired to interface the information of the portable terminal to an external device or the information of the external device to the portable terminal, a separate data cable or a charger should be used, and when it is desired to use an existing cable or an existing charger, a gender should be used, and when it is desired to use the portable terminal through the touch screen of the portable terminal, a touch pen should be used.

"Like this, although a gender and a touch pen are essential instruments or accessories in order to operate or manipulate the portable terminal, users frequently do not carry the gender and the touch pen due to the inconvenience of carrying and keeping them. For this reason, it may be impossible to use the portable terminal because the portable terminal cannot be charged from the outside, and a malfunction or erroneous input may be caused by directly touching the touch screen of the portable terminal with fingers, which makes it inconvenient to use the portable terminal.

"In addition, because the gender and the touch pen are not carried together with the portable terminal, there is high danger of losing them. Even if the gender and the touch pan are located at home or in an office, it may be difficult to locate them after a long period of time, which may consequently lead to the loss. As a result, various problems, such as inconvenience in use and economic burden, occur in that it is necessary to buy another gender and touch pen for the future use of the portable terminal by paying extra costs."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventor's summary information for this patent application: "Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and according to an aspect of the present invention, a touch pen is configured such that a user grasps the touch pen and easily touches a touch screen of a portable terminal with the touch pen, and a gender unit is configured such that the gender unit is freely accommodated in and withdrawn from the inside of the touch pen, and is capable of interfacing information from the portable terminal to an external device and vice versa, and charging the portable terminal. As a result, even in a state where a user's hands are covered, for example, by gloves, the user may easily operate the portable terminal using the touch pen, and the usefulness and convenience of use of the touch pen can be enhanced as the touch pen is provided together with the gender unit configured to conduct an interfacing between the portable terminal and an external device.

"According to the present invention, because the touch pen is configured such that a gender unit can be integrally accommodated and stored in the touch pen, it is possible to solve the inconvenience and trouble caused by separately carrying the touch pen and the gender unit. Furthermore, even in a state in which the user wears gloves, for example, in the winter season, the user's convenience that allows the user to easily conduct input to a touch screen of a portable terminal using the touch pen can be improved.

"Moreover, according to another aspect of the present invention, the touch pen may further include a portable storage device so that the touch pen can be used in place of a USB memory which is typically carried separately. As a result, the inventive touch pen has usefulness in that it can exhibit functional effects of three products, i.e. a gender, a touch pen, and a portable storage device, as a single product.
