The present invention relates to a portable terminal.

A portable terminal is a portable electronic apparatus having at least one function of being able to carry and store information by using a user, a function of allowing a user to make a voice or video call with the other party, or a function of storing data.

As the functions are diversified, the portable terminal may be equipped with functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game, or broadcasting. Such functions may be implemented in a multimedia device by being embedded in a portable terminal.

For the implementation of various functions and the operation of parts, the portable terminal requires sufficient support in terms of hardware or software. For example, research has been conducted to develop a user interface environment in which a user can easily and conveniently use a portable terminal in terms of usage.

As the portable terminal is regarded as a portable personal item, the form factor is also diversified so that the selection according to the individuality is easy. A conventional type of portable terminal is a bar type in which an input / output unit and a display unit are arranged in one body, a folder type or a swing type in which one body is rotated or opened for another body, ) Type, or a slide type in which one body is slid and opened or closed with respect to another body.

The double slide type is preferred because it has a simple opening operation and the display part is always exposed to the outside of the terminal directly, which is easy to recognize. However, when the slide length is increased in the slide type, there is a possibility that the flexible PCB, which is a means for electrically connecting the body and the body, can be exposed to the outside.

The present invention can be applied to a portable terminal that is capable of utilizing a wide user interface area by sliding a body on another body and opening and closing the body while preventing the flexible PCB from being exposed to the outside and improving the appearance of the terminal when a long stroke is implemented. There is a purpose.

In order to achieve the above object, a portable terminal according to the present invention includes: a lower body; An upper body disposed so as to overlap with the lower body and configured to realize an open state for exposing a part of the upper surface of the lower body and a closed state for covering a part by sliding movement; A flexible PCB (FPCB) electrically connecting the lower body and the upper body; And a length adjusting unit for drawing the flexible PCB into the inside of the upper body so as to reduce the length of the portion located between the upper body and the lower body when the upper body moves in the open state.

According to an embodiment of the present invention, the length adjusting unit includes: a moving bracket slidably installed on the upper body, the moving bracket having a through-hole for passing a flexible PCB; A first magnet attached to the moving bracket; And a second magnet fixed to the lower body and interacting with the first magnet to slide the moving bracket.

A contact portion may be formed on one side of the through hole so that the flexible PCB can be in contact with the flexible PCB. In this case, the contact portion may be further provided with a roller.

As one example related to the present invention, the first magnet and the second magnet may be arranged in parallel. A plurality of first magnets may be disposed along the traveling direction of the upper body. In this case, the magnetic poles of the plurality of first magnets may be arranged alternately.

As an example related to the present invention, the magnetic poles of the second magnet may be arranged so that a repulsive force acts on the first magnet when the upper body is closed. Further, the magnetic poles of the second magnet may be arranged so that a repulsive force acts on the first magnet when the upper body is fully opened.

The upper body may be formed with a stopper that limits further movement of the bracket when the upper body is fully open.

And an elasticity providing unit that provides an elastic force when the upper body moves to the open state or moves to the closed state. In this case, the elasticity providing unit may include: a first slide member fixed to the lower body; A second slide member fixed to the upper body and formed to be slidable on the first slide member; And a second slide member which is disposed between the first slide member and the second slide member and stores elastic energy while the second slide member is slidingly moved to a predetermined distance and moves the second slide member by the stored elastic energy when moved beyond a predetermined distance, And a slide spring member configured to be able to move the slide member.

As one example related to the present invention, the upper body may be configured to slide in the lateral direction. In this case, a keypad having a QWERTY arrangement may be installed on the lower body.

For example, when the portable terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141. This will be discussed later in connection with touch screens.

The interface unit 170 serves as an interface with all the external devices connected to the portable terminal 100. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, Video input / output (I / O) ports, earphone ports, and the like. Here, the identification module is a chip that stores various information for authenticating the usage right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) ), A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port. The interface unit 170 receives data from an external device or receives power from the external device, transfers the data to each component in the portable terminal 100, or transmits data in the portable terminal 100 to an external device.

The interface unit 170 may be a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle or various command signals input from the cradle by the user It can be a passage to be transmitted to the mobile terminal. The various command signals or power input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display unit 151, an audio output module 152, and an alarm unit 153.

The display unit 151 displays and outputs the information processed by the portable terminal 100. For example, when the mobile terminal is in the call mode, a user interface (UI) or a graphical user interface (GUI) associated with a call is displayed. And displays the captured or / and received image or UI and GUI.

Meanwhile, as described above, when the display unit 151 and the touch pad have a mutual layer structure to constitute a touch screen, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may include a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, Dimensional display unit (3D display). Some of them may be configured to be transparent so that they can see the outside through them. This can be referred to as a transparent display portion, and a transparent display portion is a typical example of the transparent display portion. In addition, there may be two or more display units 151 according to the embodiment of the portable terminal 100. The touch screen can be configured to detect not only the touch input position and area but also the touch input pressure.

On the other hand, the proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays. Therefore, the proximity sensor has a considerably longer life than the contact-type sensor and its utilization is also quite high. Examples of proximity sensors include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

In the high-frequency oscillation-type proximity sensor, the oscillation amplitude of the rear oscillation circuit is attenuated or stopped so that the sensing object approaches the sensor sensing surface in the state of oscillating the high frequency of the stationary wave in the oscillation circuit. Is detected. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

Even if the proximity sensor is not mounted, it may be configured to detect the proximity of the pointer with a change in the electric field along the proximity of the pointer if the touch screen is electrostatic.

Thus, in the case where the pointer is not actually touched but located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected. Hereinafter, for the sake of convenience of explanation, the act of causing the pointer to be located on the touch screen and recognizing that the pointer is located on the touch screen is referred to as "proximity touch" Quot; contact touch ". Further, the position where the proximity touch is performed with the pointer on the touch screen means a position where the pointer corresponds vertically to the touch screen when the pointer is proximity-touched.

The proximity sensor detects the rear face, the proximity touch and the proximity touch pattern (for example, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, Information corresponding to the touch operation and the proximity touch pattern can be output on the touch screen.

The audio output modules 152 and 155 output audio data received from the wireless communication unit 110 or stored in the memory unit 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output modules 152 and 155 output sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the portable terminal 100. The sound output modules 152 and 155 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the portable terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for informing occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 153 can output a vibration to notify it. Alternatively, when the key signal is input, the alarm unit 153 can output the vibration by the feedback to the key signal input. The user can recognize the occurrence of an event through the vibration output as described above. Of course, a signal for notifying the occurrence of an event may also be output through the display unit 151 or the audio output module 152 or 155.
