The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role.

The mobile terminal described in this specification may include a mobile phone, a smart phone, a laptop computer, a digital broadcasting terminal, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), navigation and the like. However, it will be understood by those skilled in the art that the configuration according to the embodiments described herein may be applied to a fixed terminal such as a digital TV, a desktop computer, and the like, unless the configuration is applicable only to a mobile terminal.

[First Embodiment]

The mobile terminal assembly according to the first embodiment of the present invention includes a mobile terminal 100 and a terminal case 200 separately provided from the mobile terminal 100 and removable from the mobile terminal.

Hereinafter, the structure of the terminal case according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

FIG. 1 is a perspective view illustrating a state where a mobile terminal 100 is coupled to a terminal case 200 according to an embodiment of the present invention. FIGS. 2a and 2b are perspective views illustrating a terminal case 200 ).

1 and 2B, a terminal case 200 according to an embodiment of the present invention includes a case body 210, a lens cover mounting portion 230 provided on the case body 210, And a lens cover 240 that is slidably mounted on the cover mounting portion 230.

To explain each of these configurations in more detail, the case body 210 has a shape in which a central portion extends substantially flat and is bent and projected forward in the vicinity of upper, lower, right, and left ends. In addition, the front side of the mobile terminal 100 has an opened shape so that the mobile terminal 100 can be attached and detached. Accordingly, the terminal case main body 210 has a space in which the mobile terminal 100 can be accommodated. When the mobile terminal 100 is coupled to the mobile terminal 100, the side surface and the back surface of the mobile terminal 100 can be covered. Meanwhile, the distance between the left and right ends of the case body 210 is narrower than the width of the left and right sides of the mobile terminal 100 to be coupled. Therefore, when the mobile terminal 100 is coupled, the left and right ends of the mobile terminal 100 are elastically deformed. After the mobile terminal is coupled, the left and right ends of the mobile terminal 100 are pressed inward by the elastic restoring force, 100 and the case body 210 can be maintained.

3 to 5, the lens cover mounting portion 230 is provided at a predetermined position of the case body 210, and the lens cover 240 is slidably coupled to the lens cover mounting portion 230. Hereinafter, First, the configuration of the lens cover 240 will be described first, and then the configuration of the lens cover mounting portion 230 will be described with reference to FIGS. 2A to 3. FIG.

FIG. 3 is a sectional view taken along line BB in FIG. 2A, FIG. 4 is a perspective view showing a lens cover 240, and FIG. 5 is a side view showing the lens cover 240.

3 to 5, the lens cover 240 includes an inner side portion 241 located inside the case body 210, an outer side portion 243 located outside the case body 220, . And an intermediate portion 242 provided between the outer side portion 243 and the inner side portion 241. The inner side portion 241 and the outer side portion 243 both have a plate shape.

The outer side portion 243 extends in a shorter direction than the inner side portion 241 along the sliding direction. In addition, the intermediate portion 242 extends shorter than the inner side portion 241.

Here, the direction in which the lens cover 240 slides is referred to as a first direction (x-axis direction), and the direction orthogonal to the first direction is referred to as a second direction (y-axis direction). Therefore, the first direction and the second direction are directions parallel to the extending direction of the flat plate constituting the inner side 241 or the outer side. On the other hand, a direction orthogonal to both the first direction and the second direction is referred to as a third direction (z-axis direction). The third direction (z-axis direction) is a direction perpendicular to the flat plate constituting the inner side portion 241 or the outer side portion. Hereinafter, the forward and backward directions used in describing the embodiment of the present invention means the third direction.

Therefore, the length of the lens cover 240 in the first direction (x-axis direction) is formed such that the inner portion 241 is the longest, the outer portion is the next longest, and the middle portion 242 has the shortest length.

3, the length of the lens cover 240 in the second direction (y-axis direction) is substantially the same in the inner side portion 241 and the outer side portion 243, and the middle portion 242 is formed to be the shortest do. That is, the length of the intermediate portion 242 in the second direction is shorter than that of the inner portion 241 and the outer portion 243. Accordingly, the lens cover 240 has a shape in which the middle portion 242 between the inner portion 241 and the outer portion is recessed inwardly inward along the second direction. This concave groove forms the guide groove 244.

On the other hand, the inner protrusion 241 is coupled with the elastic protrusion 246 protruding in the second direction. The elastic protrusions 246 are elastically deformable. Therefore, when the external force is not present, it protrudes outward, but when the external force is applied in the second direction, it retracts inward.

Meanwhile, a lens cover magnetic body 245 is coupled to the lens cover 240. The lens cover magnetic body 245 is coupled to the first direction end portion of the inner side portion 241. The lens cover magnetic body 245 is detected by the lens cover sensing unit 141 which is built in the mobile terminal 100 to be described later so that the control unit 180 can grasp the open / . For reference, the lens cover sensing unit 141 may be a hall sensor for sensing the magnetic field of the lens cover magnetic body 245.

On the other hand, the outer edge of the outer side portion 241 is inclined. More specifically, the outer side portion 241 has a shape in which the outer sides of both ends in the first direction to be slid are inclined. With this structure, it is possible to prevent the angle of view from becoming narrow due to the outer side portion 241 when the camera module 121 is operated. That is, the maximum angle of view can be ensured.

Hereinafter, the configuration of the mounting portion of the lens cover 230 in which the lens cover 240 having the above-described structure is slidably coupled will be described.

2A and 2B, the lens cover mounting part 230 is formed by recessing the inner side surface of the case body 210 so as to be stepped outward. That is, the inner side is formed to be depressed outward along the third direction (z-axis direction). At this time, the recessed depth of the lens cover mounting part 230 is substantially equal to the third direction thickness of the inner side part 241 of the lens cover 240, or deeper than the inner side part 241.

The lens cover mounting part 230 is formed with a rear cutout part 231 extending in the first direction. The rear cutout portion 231 is formed to penetrate the case body 210 in the third direction, has a predetermined width in the second direction, and extends in the first direction.

The lens cover mounting portion 230 is provided with a guide protrusion 232 (see FIG. 3) inserted into the guide groove 244 of the lens cover 240 described above. The guide protrusion 232 is inserted into the guide groove 244 of the lens cover 240 and is an edge portion of the back cut portion 241 extending along the first direction. The width of the guide protrusion 232 in the third direction may be the same as that of the other portions of the case body 210. However, it is also possible that the width of the guide protrusion 232 in the third direction is thicker or thinner than other portions.

The lens cover mounting portion 230 is provided with protrusion insertion portions 233a and 233b into which the elastic protrusions 246 can be inserted. The protrusion insertion portions 233a and 233b may be formed on the stepped surface 234 of the mounting portion of the lens cover 240. Here, the stepped surface 234 is a stepped portion between the lens cover mounting portion 230 formed by recessing and an outer portion thereof, and is a surface facing substantially in the second direction (y-axis direction). The projection insertion portions 233a and 233b have a shape in which a part of the stepped surface 234 is recessed in the second direction.

A plurality of the projection insertion portions 233a and 233b are formed along the first direction. For example, when the lens cover 240 is closed, the first protrusion insertion portion 233a into which the elastic protrusion 246 is inserted and the elastic protrusion 246 when the lens cover 240 is opened, And a second projection insertion portion 233b. Therefore, when the lens cover 240 is opened, the elastic protrusion 246 inserted in the first protrusion insertion portion 233a is removed from the first protrusion insertion portion 233a And can be inserted into the second projection insertion portion 233b after sliding along the first direction.

3, the slide of the lens cover 240 is guided by the guide protrusion 232 inserted into the guide groove 244. In this case, as shown in FIG.

6A and 6B, the structure of the mobile terminal 100 that can be coupled to the terminal case 200 having the above structure will be described. Referring to FIGS. 7A and 7B, A process of opening and closing the back cut section 231 will be described.

Hereinafter, the configuration of the mobile terminal will be briefly described with reference to FIGS. 7A and 7B, and then a physical operation method of the lens cover will be described. Figs. 7A and 7B are cross-sectional views showing a mobile terminal coupled to a case, and Fig. 1 is a sectional view cut along the line AA. Fig. 7A shows the lens cover closed, and Fig. 7B shows the lens cover opened.

A display unit 151 for displaying an image is provided in the mobile terminal. A touch input unit 131, which is a part of the user input unit 130, is provided in front of the display unit 151 (in FIGS. 7A and 7B). A printed circuit board 181 to which the control unit 180 is coupled is disposed at the rear of the display unit 151.

The camera module 121 is provided at a central portion of the printed circuit board 181 and senses whether the lens cover is opened or closed at a predetermined distance from the camera module 121 in the left- And a lens cover sensing unit 141 for sensing the lens cover. The lens cover sensing unit 141 may be a hall sensor for sensing whether or not the lens cover magnetic body 245 coupled to the lens cover 240 is approaching.

7A, when the lens cover 240 is closed in the terminal case 200 and the mobile terminal 100, the lens cover magnetic body 245 coupled to the lens cover 240 is rotated by the lens And is located inside the sensing area of the cover sensing unit 141. The lens cover magnetic sensing unit 141 senses the magnetic field of the lens cover magnetic body 245 and senses whether the lens cover 240 is open or closed. The lens cover sensing unit 141 senses this and detects that the lens cover 240 is closed.

7B, when the lens cover 240 is opened and the lens cover magnetic body 245 moves away from the lens cover sensing portion 141 and out of the sensing area of the lens cover sensing portion 141, The cover sensing unit 141 can sense that the lens cover 240 is opened.

On the other hand, when the lens cover 240 slides in the lens cover mounting portion 230, the guide protrusion 232 is held inserted into the guide groove 244, as shown in FIG. 3, The sliding of the lens cover 240 can be guided by the guide grooves 232 and the guide grooves 244.

Hereinafter, a method of operating the mobile terminal 100 according to an embodiment of the present invention will be described in detail with reference to FIG. More specifically, an operation method of the controller 180 according to whether the lens cover 240 is open or closed will be described.

8 is a flowchart illustrating an operation of a mobile terminal according to an exemplary embodiment of the present invention.

Before describing each step shown in FIG. 8, the entire operation method will be briefly described. First, when the user closes the closed lens cover 240 and opens the lens cover 240 into an open state, The camera lens 121a is exposed to the outside. At this time, the sensing unit 140 senses the opening of the lens cover 240. The control unit 180 activates the camera application if it is determined that the lens cover 240 is opened. At this time, the operation of the camera application may be started in any one of a shooting mode and a camera pre-view mode. Accordingly, the controller 180 may select the camera preview mode to display the camera preview mode interface on the display unit 151, or may select the shooting mode to display the shooting mode user interface on the display unit 151 . For reference, the photographing mode refers to a photographing mode that can be photographed by user input, and the camera preview mode refers to a mode in which photographing by user input is restricted.

Hereinafter, with reference to FIG. 8, an operation process of the controller 180 to execute the camera application in either the photographing mode or the camera preview mode will be described in detail.

First, the control unit 180 receives a signal for opening the lens cover 240 from the sensing unit 140 (S201).

When the open state of the lens cover 240 is received, the control unit 180 determines whether the current display unit 151 is on or off (S202).

If the display unit 151 is on, the control unit 180 determines whether or not an exceptional state exists (S203). The exception state is set to a state in which the free use of the mobile terminal is limited or a task is to be performed in priority, such as a state in which a screen lock is established (lock screen) or a call state (in call). The concept opposite to the exception state is the general state, and the normal state is set to the rest state other than the exception state. Therefore, in a normal state, the mobile terminal can be freely used through a touch operation or the like. Accordingly, when the display unit 151 is turned on, the display unit 151 is placed in either a normal state or an exceptional state.

If it is determined that the state of the display unit 151 is an exception state, the controller 180 enters a camera pre-view mode (S204). That is, the camera preview mode is selected, and the camera application is executed in the camera preview mode. Therefore, the camera preview mode interface is displayed on the display unit 151. [ The interface of the camera preview mode includes an interface 301 of a photographing mode and an unlocking interface 302, which will be described later. Therefore, although the interface of the photographing mode is outputted in the camera preview mode, if the lock state is released by operating the unlocking interface that is output together, or if the priority operation state such as the call state is not canceled, the touch input for photographing is not accepted State is maintained.

In this state, the user can perform a touch input for unlocking to release the screen lock state.

The control unit 180 determines whether the screen lock state is released in the camera preview mode (S205).

Then, when the control unit 180 receives the screen unlocking signal from the touch unit as a result of the determination, the locked state is canceled and the photographing mode is entered (S206). That is, the photographing mode is selected. At this time, the control unit displays the photographing mode interface 301 of the camera application through the display unit 151. Therefore, the user can shoot a desired subject using the camera application.

If it is determined in step S203 that the controller 180 is in the exceptional state, it is determined that the general state is not the exceptional state. That is, the control unit 180 selects the photographing mode and displays the interface 301 of the photographing mode through the display unit 151. Accordingly, the user operates the interface 301 of the photographing mode to photograph do.

If it is determined in step S202 that the display unit 151 is off, the controller 180 determines whether the display unit 151 is in the screen lock state (S208).

If it is determined that the screen is locked, the control unit 180 enters the camera preview mode (S209). That is, the camera preview mode is selected, and the camera application is executed in the camera preview mode. Therefore, the display unit 151 is displayed with the unlocking interface 302 together with the shooting mode interface 301. [ In other words, in the camera preview mode, although the interface 301 of the photographing mode is outputted, if the lock state or the priority operation state is not released by operating the unlocking interface 302 to be outputted together, do.

In this state, the user can perform a touch input for unlocking to release the screen lock state.

The control unit 180 determines whether the screen lock state is released in the camera preview mode (S210). Then, when the control unit 180 receives the lock release signal from the touch unit as a result of the determination, the locked state is canceled and the camera enters the shooting mode (S211). That is, the photographing mode is selected. In the shooting mode, the control unit 180 outputs the shooting mode interface 301 of the camera application through the display unit 151. [ Therefore, the user can shoot a desired subject using the camera application.

On the other hand, if it is determined in step S208 that the screen lock state is not set, the control unit 180 enters the shooting mode (S212). That is, the photographing mode is selected. Then, the control unit 180 outputs the photographing mode interface 301 of the camera application through the display unit 151. Therefore, the user can shoot a desired subject using the camera application.

9 to 12 show the user interface provided in the process described above.

First, Fig. 9 is a diagram showing an image displayed on the display unit when the lens cover is opened in the display unit on state and the exceptional state. More specifically, the interface of the camera preview mode is output to the display unit 151 as the display unit 151 is turned on and the step S204 is performed in the exceptional state. As described above, the interface 151 of the photographing mode and the unlocking interface 302 are displayed together as the camera application is performed on the display unit 151. [ FIG. 9 shows an exemplary screen for inputting 4-digit passwords as an example of various scenarios for unlocking, but various other unlocking scenarios may be provided.

On the other hand, Fig. 10 is a diagram showing an image displayed on the display unit when the lens cover is opened in the display unit on state and the normal state. More specifically, in the on and normal states of the display unit 151, the photographing mode interface 301 is provided as the step S207 is performed. In this state, the user can perform shooting by short-touching or long-touching the shooting icon.

On the other hand, FIG. 11 shows an image displayed on the display unit when the lens cover is opened in the display off state and the screen lock setting state. More specifically, in a state in which the display unit 151 is turned off and the screen lock is set, the lens cover 240 is opened and the step S209 is performed. When the control unit 180 enters the camera preview mode The display section 151 of the display section 151 shown in Fig. That is, the screen of the display unit in step S209. In this state, the control unit 180 executes the camera application and outputs the interface 301 of the photographing mode and the unlocking interface 302 to the display unit 151 together. At this time, as one of various scenarios that can be provided to release the lock, an unlocking method capable of releasing the lock by dragging and dropping the pattern can be provided.

In the state shown in Fig. 11, when the user performs a touch input for unlocking, the screen lock state can be canceled and the user can enter the photographing mode. That is, the photographing mode can be selected.

12 is a view showing an image displayed on the display unit when the lens cover is opened in a state in which the display unit is turned off and the screen is not locked. More specifically, when the opening signal of the lens cover 240 is input to the control unit 180 in the display off state and the screen unlocked state, the control unit 180 executes the photographing mode of the camera application, So that the photographing mode interface 301 is displayed on the display 151.

13 to 17, a description will be given of a method of operating the mobile terminal when the lens cover 240 is operated from the off state to the On state, contrary to the above description. More specifically, with reference to FIG. 13 and FIG. 14, a description will be given of a change of the user interface when the opened lens cover is closed while the camera application is not being executed. Referring to FIGS. 15 to 17, And shows the display unit when the lens cover that has been opened is closed while the application is being executed.

Hereinafter, the examples shown in Figs. 13 to 17 will be examined in detail in order.

13 is a diagram showing an image displayed on the display unit when the display unit is turned on and the lens cover opened in the normal state is closed. 13, no change occurs in the user interface even when the camera lens 14 is closed when the display unit 151 is in the on-state and not in the shooting mode or the camera preview mode. That is, when the display unit 151 is in the ON state and is not in the photographing mode or the camera preview mode, the control unit 180 performs a separate operation for switching the user interface .

This is true even when the display unit 151 is off as shown in Fig. 14 is a diagram showing an image displayed on the display unit when the lens cover opened in the off state of the display unit is closed. When the display unit 151 is turned off and the lens cover 240 is closed, the display unit 151 is kept in the off state. That is, if the display unit 151 is off and the camera lens 14 is closed, the control unit 180 performs a separate operation for switching the user interface Do not.

15 to 17, when the control unit 180 is provided with the user interface of the photographing mode or the camera preview mode through the display unit 151, When the lens cover 240 is turned off, the control unit displays a screen before the interface of the shooting mode or the camera preview mode is displayed through the display unit 151.

15 is a diagram showing an image displayed on the display unit when the lens cover is opened and the screen lock state is released and the lens cover is closed again after entering the photographing mode in the display unit on state and the exceptional state . Referring to FIG. 15, when the screen lock is released in step S204 and a closed signal of the lens cover 240 is received when entering the photographing mode through the step S206 of FIG. 8 described above, The controller 180 ends the camera preview mode and displays the image before switching to the camera preview mode. That is, an image guiding the screen lock state is output. However, in the case of a swipe, the unlocked screen is displayed instead of the unlocked screen.

16 is a diagram showing an image displayed on the display unit when the lens cover is opened and the screen lock state is released and then the lens cover is closed again after entering the photographing mode in the display unit on state and the normal state . Referring to FIG. 16, when the photographing mode is entered through the step S207 of FIG. 8 described above, the control unit 180 terminates the photographing mode when a closed signal of the lens cover 240 is received, And displays the image before switching to the photographing mode.

17 is a view showing an image displayed on the display unit when the lens cover is opened in the off state of the display unit and the apparatus is put in the shooting mode and then the lens cover is closed again. 17, when the camera preview mode or the photographing mode is outputted through the display unit 151 through the above-described step S212 of FIG. 8, when a closed signal of the lens cover 240 is received, The controller 180 terminates the camera preview mode or the photographing mode and turns off the display unit 151 to return the original display unit 151 to the off state.

18 shows a user interface when the camera application is executed through the operation of the mobile terminal, but the lens cover 240 is kept closed and the photographing is impossible. In this case, the control unit 180 can output a guidance message such as "the lens cover is closed" or a guidance message "open the lens cover"

In this state, when the lens cover 240 is opened by the user's operation, the control unit 180 can output an image for displaying the image, for example, an animation showing a state in which the shutter of the camera is opened.

On the other hand, in step S207 or step S212, the controller 180 sets the photographing to be performed at the moment when the lens cover is opened, so that the photographing can be performed quickly. At this time, photographing may be performed at the moment when the lens cover is opened, and may be set to be performed after a time delay for a predetermined time. For example, it may be set so that the first photographing is automatically performed after 1 second after the lens cover is opened.

Therefore, repetitive description of the configuration of the case body 210 is omitted.

The front cover 220 is a plate-shaped member having a shape corresponding to the front surface of the mobile terminal 100. The front cover part 12 is provided with a front cutout part 221. The front incision part 221 is formed by cutting a part of the front cover part 220. Accordingly, the user can view an image or an image displayed on the display unit 151 of the mobile terminal 100 through the front cutout unit 221, or perform a touch input.

A front cover magnetic body 222 may be mounted on the front cover 220. When the front cover magnetic body 221 is mounted on the front cover part 220, the magnetic field changes as the front cover part 220 is opened and closed, and this can be detected by the mobile terminal 100.

In addition, the surface of the front cover 220 contacting the front surface of the mobile terminal 100 may be subjected to static electricity prevention processing to prevent unintended touch input by the user. A material for preventing generation of static electricity may be applied to the front cover 220 for preventing the generation of static electricity, or a film for preventing generation of static electricity may be attached.

Hereinafter, a configuration of a mobile terminal according to a fourth embodiment of the present invention will be described. The mobile terminal according to the present embodiment includes a front cover sensing unit 143 for sensing whether the front cover unit 220 is opened or closed. 33, the mobile terminal according to the present embodiment includes a display panel 151, a touch input unit 131, a printed circuit board 182, a front cover sensing unit 143, The configuration other than the addition of the part 143 is the same as or similar to the structure of the mobile terminal in any of the first to third embodiments described above, and thus a repetitive description thereof will be omitted.

Accordingly, one end of the connection part 250 is coupled to the case body 210, and the other end is coupled to the front cover part 220. The connection part 250 is made of a flexible material. Therefore, in a state where the mobile terminal 100 is coupled to the case body 210, the front cover 220 may be placed at a position where the back surface contacts the front surface of the mobile terminal, (Not shown).

34 and 35, the interface provided by the mobile terminal and the terminal case according to the present embodiment will be described.

The mobile terminal 100 has a first user interface mode and a second user interface mode. In addition, the display unit 151 of the mobile terminal includes a first display region 410 in which an image is displayed in a first user interface mode and a second display region 420 in which an image is displayed in a second user interface mode .

The first display area 410 may correspond to the cutout 221 of the front cover 220 and the second display area 420 may be the entire active area of the display 151 . Accordingly, the first display area 410 may be a part of the second display area 420. [

In the first user interface mode, the control unit 180 provides the first user interface 410 to the first display area 410.

The first user interface mode is an operation mode of the mobile terminal 100 providing a user interface through the front cutout 221 of the front cover 220 when the front cover 220 of the terminal case 200b is closed . In the first user interface mode, the mobile terminal 100 may receive a touch input through the first display area 410. [ Accordingly, the user can view the displayed image or perform touch input even when the front cover 220 of the terminal case 200a is not opened.

Meanwhile, in the first user interface operation mode, the controller 180 stops the display and restricts the touch input to the area 420 excluding the first user interface. That is, when it is possible to turn on and off some pixels of the display unit 151, the controller 180 may turn off the pixels of the area except for the first display area 410 in the first user interface mode . The control unit 180 may display the outside of the first display area 210 in black, if it is impossible to turn on or turn off some pixels of the display unit 151. [

On the other hand, when entering the first interface mode, the controller may ignore the touch signal input through the area other than the first display area 410. [

 The second user interface mode is a mode in which the display part 151 of the display part 151 is activated when the front cover part 220 of the terminal case 200b is opened or when the mobile terminal 100 is separated from the terminal case 200b. area of the mobile terminal 100 that provides the user interface.

The switching between the first user interface mode and the second user interface mode may be performed based on the sensing information of the front cover sensing unit 143. [

That is, the controller 180 receives the detection information of the front cover sensing unit 143, and if it determines that the front case is closed, it can enter the first user interface mode. In this case, a first user interface is provided through the first display area 410.

On the other hand, if the control unit 180 receives the detection information of the front cover sensing unit 143 and determines that the front case 220 is opened, the user can enter the second user interface mode. In this case, a second user interface is provided through the second display area 420.

Therefore, the user can perform various operations such as receiving a call, executing music, checking the weather, etc. without opening the front cover 220 of the terminal case 10. [

In addition, when events that need to be notified to the user occur, such as a phone call or a text message being received, the applications corresponding to the events can be executed in the first user interface mode, 220 can be opened without opening the various events.

Meanwhile, the size or position of the first display area 410 may be changed by a user. 35 is a diagram showing that the size or position of the first display area 410 can be changed. Therefore, even if the size or position of the front cutout 221 changes, the first display area 410 can be set to correspond to the new cutout 221 by replacing the terminal case 200b.

The controller 180 may receive a user input for changing the size and position of the first user interface 200 by moving a graphic representing the first display area 410 displayed on the display unit 151 There may be a way to receive a touch input that changes its size. On the other hand, the controller 180 may set the position and size of the first display area 410 based on the numerical input of the size and the coordinates from the user.

Meanwhile, the light sources for providing light to the display unit 151 may be turned on or off differently in the first user interface mode and the second user interface mode, respectively.

36 and 37, an operation method of the mobile terminal according to the state change of the front cover part 220 of the terminal case 200b according to the fourth embodiment of the present invention will be described.

36 is a flowchart illustrating an operation of the mobile terminal when the state of the front cover 220 of the terminal case is changed.

The front cover sensing unit 143 detects a state change of the front cover 220 of the terminal case 200a (S101). The state of the front cover portion 220 includes a change from open to closed and a change from closed to open.

The control unit 180 determines whether the display unit 151 is currently turned on (S103). If only a partial area of the display unit 151 is turned on, it is determined that the display unit 151 is turned on.

The control unit 180 determines the current user interface mode according to the state of the front cover 220 and the turn-on of the display unit 151 (S105).

If the current display unit 151 is turned on and the state of the front cover unit 220 is changed from open to closed, the controller 180 determines the current user interface mode as the first user interface mode. That is, the control unit 180 executes the application in the first user interface 200. [ The basic application of the first user interface executed at this time may be changed according to the user's selection.

Fig. 37 shows a display screen of a display unit executed in a camera application, which changes as the case cover is opened and closed.

As shown in the left drawing, the user interface displayed through the entire display unit is reduced to a size and position corresponding to the front incision part as the front cover part 220 is closed.

Therefore, as described in the first to third embodiments, when the lens cover 240 is opened or closed, the image displayed on the display unit 151 is displayed in a state where the front cover 220 is closed May be displayed only through the display area 410 and may be controlled to be displayed through the second display area 420 when the front cover part 220 is open.
