For instance, the memory 170 may be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the controller 180 to perform an operation (or function) for the mobile terminal 100.
The controller 180 typically functions to control overall operation of the mobile terminal 100, in addition to the operations associated with the application programs. The controller 180 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1, or activating application programs stored in the memory 170.

The power supply unit 190 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.
Referring still to FIG. 1, various components depicted in this figure will now be described in more detail. Regarding the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.
The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like).

One example of the wireless area networks is a wireless personal area networks.
In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180, for example, may cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device may use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user may answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.
The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal.
As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.
The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.
The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.
The user input unit 123 is a component that permits input by a user. Such user input may enable the controller 180 to control operation of the mobile terminal 100. The user input unit 123 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.
The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.
The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.
The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.
The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like).
In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.
A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.
In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.
Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images. A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.
An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.
A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.

FIG. 2 is a perspective view illustrating a configuration of the mobile terminal 200 according to an embodiment of the present invention, and FIG. 3 is a perspective view illustrating a plurality of segments 230 shown in FIG. 2 which have moved to be adjacent to each other.
Referring to FIGS. 2 and 3, the mobile terminal 200 includes a band unit 210 configured to be fastened to a users body. The users body may be one part of the body on which the mobile terminal 200 may be worn.
The band unit 210 may include a deformation part 220, a plurality of segments 230 and a module unit 240.
The deformation part 220 is elastic and deformable. The deformation by elasticity may mean a property to be deformed when a load such as extension and compression is applied and to return to its original form when the load is removed. Meanwhile, the deformation by the elasticity may include a deformation to return to its original form by a restoration force after being deformed by another factor, rather than a load. For instance, the deformation part 220 may be formed by a material having elasticity such as silicon and urethane.
The plurality of segments 230 are formed to cover the deformation part 220 in a state that they are adjacent to each other and to expose at least part of the deformation part 220 to the outside in a state that they are spaced from each other. Here, it is preferable to form the plurality of segments 230 to entirely cover the deformation part 220 without exposing any part to the outside.
And the plurality of segments 230 enclosing the band unit 210, wherein the plurality of segments 230 are movable to cover or expose a portion of the deformation part 220, the portion covered by the plurality of segments 230 when all of the plurality of segments 230 are arranged to be adjacent to each other and the portion is exposed when at least two of the plurality of segments 230 are arranged to be spaced apart from each other.
And the plurality of segments 230 are configured to receive a restoration force by elasticity of the deformation part 220 by a fixing part (not shown) provided in the mobile terminal 200. Specifically, the fixing part may be disposed between facing surfaces of the deformation part 220 and the plurality of segments 230 and configured to fix the deformation part 220 and the plurality of segments 230. For instance, the fixing part may be formed of a material to adhere different things to each other, or may be implemented to have a mechanical structure which can fixedly couple the deformation part 220 and the plurality of segments 230 with each other.
According to the fixing structure of the deformation part 220 and the plurality of segments 230, there is an advantage in that it is possible to easily implement movement of the plurality of segments 230 by receiving a restoration force by elasticity from the deformation part 220, without an additional external force.
Further, as shown in FIG. 2, the plurality of segments 230 are formed along a lengthwise direction D1 of the band unit 210 in a divided manner so as to be adjacent to each other or to be spaced from each other in the divided state, thereby selectively exposing at least part of the deformation part 220. Further, the plurality of segments 230 may also be formed so as to be adjacent to each other or to be spaced from each other in a divided state in a widthwise direction of the band unit 210, not in the lengthwise direction D1. Further, each of the plurality of segments 230 is shown in FIG. 2 to have one surface facing a users hand in a rectangular shape, but not limited thereto. That is, the plurality of segments 230 may be formed to have a concavo-convex shape corresponding to each other.
Meanwhile, though not shown, the plurality of segments 230 may be formed of a light-transmissible material which permits light to transmit therethrough. According to the aforementioned structure, it is possible to implement a mobile terminal in which the deformation part 220 or the module unit 240 can be seen from the outside even in a state that the plurality of segments are disposed to be adjacent to each other.
The module unit 240 is configured to execute specific functions which can be implemented in the mobile terminal 200, and disposed such that at least part of the module unit 240 may be accommodated in the deformation part 220 by being selectively exposed by the plurality of segments 230. Here, the module unit 240 may be configured to execute the specific functions in an accommodated state in the deformation part 220 without being exposed to the outside of the deformation part 220, and may be configured to execute the specific functions in a state that at least part thereof has been exposed to any one surface of the deformation part 220.
Referring to FIGS. 2 and 3, the mobile terminal 200 may further include a body part 250 which contains therein elements for implementing the mobile terminal 200. The specific structure of the body part 250 will be described hereinafter with reference to FIGS. 15 through 17.
According to the mobile terminal 200 as described hereinbefore, since a user can selectively expose and use the corresponding module unit 240 when he/her desires to use a specific function, it is possible to enhance a durability of the mobile terminal 200 by protecting the module unit 240 from an external environment. Further, since the module unit 240 is not exposed to the outside in an ordinary state by the plurality of segments 230, as shown in FIG. 2, it is possible to implement a mobile terminal 200 of a new type and design unlike the conventional one.
Hereinafter, the band unit 210 will be additionally described with reference to FIGS. 4A and 4B.

The power terminal 240a′ may preferably be disposed to be exposed to one surface opposite to part of a users body where the band unit 210 is fastened, thereby capable of easily contacting an external power source. But the power terminal 240a′ may be disposed to be exposed to another surface of the deformation part 220.
Meanwhile, as shown in FIG. 4A, the module unit 240 may include a camera unit 240d disposed to be exposed to any one surface of the deformation part 220 except one surface facing part of the users body where the band unit 210 is fastened, and configured to receive an image signal (data).
Meanwhile, the mobile terminal 200 may further include a flexible circuit board 215.
The flexible circuit board 215 may be electrically connected to the module unit 240 and disposed in the deformation part 220.

Further, the deformation part 220 may include an accommodation space 220a. 
The accommodation space 220a of the deformation part 220 may be provided as an empty space of a preset size in which one region of the flexible circuit board 215 may be accommodated in a rolled or overlapped state by being folded, as the plurality of segments 230 are spaced from each other or adjacent to each other. There is schematically shown in FIG. 4B an example of the accommodation space 220a, but the shape of the accommodation space 220 is not limited thereto.
Further, referring to FIG. 4A, the mobile terminal 200 may further include a frame 280 and a switch unit 285 for fixing the plurality of segments 230 which are moving to a preset position. The specific structure of the frame 280 and the switch unit 285 will be described with reference to FIGS. 9A through 12B.
Hereinbelow, an example of a power supply through the power connection part 240a from an external power source will be described in more detail with reference to FIGS. 5 through 8.

FIG. 7 is a perspective view illustrating a connected state between the charging kit 10 and the power connection part 240a of FIG. 6, viewed from a side, and FIG. 8 is a cross-sectional view taken along line A-A in FIG. 7.
Referring to FIGS. 5 through 8, the power connection part 240a is exposed to the outside in a state that the plurality of segments 230 are spaced from each other, as shown in FIG. 6A. Thereafter, as shown in FIG. 6B, the power connection part 240a can receive a power required to drive the mobile terminal 200 by connecting the power terminal 240a′ to the charging kit 10 which is inserted from a side surface of the band unit 210. The power supplied from the outside may charge a battery (not shown) provided at the mobile terminal 200.
Here, the charging kit 10 may include a first body 11 directly and electrically connected to the power connection part 240a and a second body 12 configured to connect the first body 11 to an external power source and transmit the power to the first body 11. As shown in FIG. 8, the first body 11 is formed of a conductive material and may include a contact region 11a directly contacting the power terminal 240a′. 
As describe hereinabove, there is an advantage in that it is possible to supply a power required to drive the mobile terminal 200 even in a state that the mobile terminal 200 is worn on any one part of a users body.
Hereinafter, the structure of the frame 280 and the switch unit 285 provided at the mobile terminal 200 according to the present invention will be described with reference to FIGS. 9A through 12B.

Referring to FIGS. 9A through 12B, the mobile terminal 20 may further include the frame 280 and the switch unit 285.
The frame 280 may include a module unit 240 (refer to FIG. 2) having a camera mounting portion 240d on which a camera unit is mounted, wherein the frame is coverable or exposable to the outside by the plurality of segments 230. Further, the frame 280 may include an opening type empty space 280b through which a rear surface of the deformation part 220 may be exposed to the outside in a state that the plurality of segments 230 are spaced from each other. Thus, since a rear surface of the deformation part 220 is exposed to the outside even in a state that the module unit 240 is mounted on the frame 280, there is an advantage in that rear surfaces of the deformation part 220 and the module unit 240 which are exposed to the outside can be utilized.
The switch unit 285 is mounted to each of the plurality of segments 230 and coupled to the frame 280 in a state that the plurality of segments 230 are spaced from each other, thereby limiting movement of the plurality of segments 230.

FIG. 19 is a perspective view illustrating one example of a watch-type mobile terminal 300 in accordance with another exemplary embodiment.
As illustrated in FIG. 19, the watch-type mobile terminal 300 includes a main body 301 with a display unit 351 and a band 302 connected to the main body 301 to be wearable on a wrist. In general, mobile terminal 300 may be configured to include features that are the same or similar to that of mobile terminal 100 of FIG. 1.
The main body 301 may include a case having a certain appearance. As illustrated, the case may include a first case 301a and a second case 301b cooperatively defining an inner space for accommodating various electronic components. Other configurations are possible. For instance, a single case may alternatively be implemented, with such a case being configured to define the inner space, thereby implementing a mobile terminal 300 with a uni-body.
The watch-type mobile terminal 300 can perform wireless communication, and an antenna for the wireless communication can be installed in the main body 301. The antenna may extend its function using the case. For example, a case including a conductive material may be electrically connected to the antenna to extend a ground area or a radiation area.

In some embodiments, the display unit 351 includes a touch sensor so that the display unit can function as a touch screen. As illustrated, window 351a is positioned on the first case 301a to form a front surface of the terminal body together with the first case 301a. 
The illustrated embodiment includes audio output module 352, a camera 321, a microphone 322, and a user input unit 323 positioned on the main body 301. When the display unit 351 is implemented as a touch screen, additional function keys may be minimized or eliminated. For example, when the touch screen is implemented, the user input unit 323 may be omitted.
The band 302 is commonly worn on the user's wrist and may be made of a flexible material for facilitating wearing of the device.

The band 302 may include fastener 302a. The fastener 302a may be implemented into a buckle type, a snap-fit hook structure, a Velcro® type, or the like, and include a flexible section or material. The drawing illustrates an example that the fastener 302a is implemented using a buckle.
As described hereinbefore, according to the mobile terminal of the present invention, the band unit includes a deformation part for accommodating at least part of a module unit configured to execute a specific function, and a plurality of segments formed to cover the deformation part. Accordingly, when a user wants to use a specific function, it is possible to selectively use a corresponding module unit by exposing it to the outside so that the module unit may be protected from an external environment. This can enhance the durability of the mobile terminal and implement a newly designed mobile terminal as the module unit is not exposed to the outside.
Further, according to the structure of elastically deformable deformation part, it is possible to easily move the plurality of segments so as to be adjacent to each other to cover the deformation part, by providing a restoration force by elasticity to the plurality of segments, without an additional external force.
Further, it is possible to supply a power to the mobile terminal by the power connection part disposed at the band unit, even in a state that the mobile terminal is worn on part of a users body.
