The present invention relates to a button structure of a personal handheld terminal and a personal handheld terminal including the same. Instead of an infrared port that is already used, a short cut button made of a material capable of passing short-range communication radio waves is formed, and a short distance is located below the short cut button. By arranging a sensing unit for wireless communication, the present invention relates to a button structure of a personal portable terminal and a personal portable terminal including the same, which can improve utilization efficiency of a mounting space.

Personal handheld terminals are mainly for portable purposes, and various products are being developed to meet various needs of consumers. Therefore, referring to a mobile phone released these days, not only a telephone call, which is an original function, but also music and movie watching as well as products that can transmit and receive data through infrared communication are being released.

These mobile communication terminals may be generally classified into a flip method, a folder method, and a sliding method according to their appearance or operation method. The flip method generally refers to a method of forming a display unit such as a liquid crystal display (LCD) and a key input unit on the same body, and protecting the key input unit or receiving a call by using a cover connected to the bottom by a hinge. In addition, the folder method may be opened and closed by connecting two folder parts by a hinge, and means a method of forming a main display unit and a key input unit on the surfaces facing each other. Finally, the sliding method refers to a method in which two sliding parts are disposed to overlap each other, and the display unit and the key input unit face the same direction in each sliding part. In general, the sliding method may slide the front sliding part relative to expose the display unit or the key input unit hidden on the rear surface.

These personal handheld terminals are equipped with a plurality of run buttons on the front side as various additional functions are developed, and wireless communication terminals are mounted on the sides of the wireless terminal as the near field communication is gradually developed.

The user contacts the button region 151 to transmit the contact signal to a circuit component or the like provided in the circuit board 153.

The sensing unit 154 for short-range wireless communication is mounted below the circuit board 153, and more specifically, below the circuit board 153. The sensing unit 154 is fixedly mounted to the rear surface of the circuit board 153 and the connection table 155.

Elements on the upper side of the sensing unit 154, for example, a part of the circuit board 153, the touch sensor 152, the button area 151, or the like, may be a signal for wireless communication (for example, infrared or And other radio waves) is preferably formed of a material that can pass.

When the user comes into contact with the button area 151, the signal is transmitted to the circuit components of the circuit board 153 whether the contact is made. When sensing that the button area 151 is pressed on the circuit board 153, the sensing unit 154 operates. In this case, the display 210 may show a menu screen inquiring whether or not short-range communication. When the user executes short-range communication by pressing a check button or the button region 151 again, such as a question asking whether a short-range communication is present on a menu screen, the sensing unit 154 is operated to start short-range communication.

That is, in an increasingly complex personal mobile terminal having a high function, by installing a specific function button for short-range communication on the front side of the sensing unit on its side, short-range wireless communication is possible with only one or two pressing operations. The user's convenience is enhanced.

In addition, by forming a shortcut button made of a material that can pass radio waves for short-range communication instead of the infrared port that is already used, and by placing a sensing unit for short-range wireless communication below the shortcut button, to improve the utilization efficiency of the mounting space It can be effective.
