Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 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 case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The cover 200 is formed by combining the inner cover 210 and the outer cover 220 but other members other than the adhesive member are inserted between the inner cover 210 and the outer cover 220 The inner cover 210 and the outer cover 220 can be engaged with each other.

A convex portion 134 is formed on the side surface of the terminal body 104 along the width direction of the terminal body 104. The cover portion 200 covers a front surface and a side surface of the terminal body 104 Or cover the rear and side surfaces of the terminal body 104. [ At this time, the protrusion 134 is caught in the thickness direction of the terminal body 104. Accordingly, the cover unit 200 can not be easily detached from the mobile terminal 100.

The cover part 200 according to an embodiment of the present invention can move on the terminal body 104 in a sliding manner. For example, when the terminal body 104 and the cover part 200 are slid by rail coupling And there may be a method of sliding movement using a magnetic force. However, in the following description, the sliding movement of the cover unit 200 while being coupled to the mobile terminal 100 will be described.

Since the cover part 200 is formed to cover a part of the display part 151, when the cover part 200 slides on the window 151a, scratches may occur in the window 151a , The cover portion 200 should not be in direct contact with the window 151a. 6C, the window 151a is seated in the terminal body 104 (more specifically, the front case 101), and the front case 101 And a recess portion 101b is formed in the rim portion 101a and the window 151a is formed in the recess portion 101a, And is accommodated in the portion 101b. The recess portion 101b is formed between the rims 101a and the window 151a is disposed to be lower than the rim portion 101a.

The window 151a is recessed from the rim portion 101a of the terminal body 104 so that the cover portion 200 is spaced apart from the window 151a without contacting the window 151a, The front case 101 and the front case 101 are made to contact each other.

6D is a sectional view of the cover unit 200. The cover unit 200 includes a front face 200a covering the front face or the rear face of the terminal body 104 and a front face 200b extending from the front face 200a, And side surfaces 200b and 200c covering both side surfaces of the side surface portions 200a and 200b.

The side parts 200b and 200c of the cover part 200 slide in contact with the side surface of the terminal body 104. At this time, the side parts 200b and 200c of the cover part 200 are overlapped with the side surface of the terminal body 104. However, it is not necessary that all of the side portions 200b and 200c contact the side surface of the terminal body 104, so that the cover portion 200 may be contacted only to the extent that the cover portion 200 is not separated from the mobile terminal 100 during the slide movement. At this time, the frictional force between the side portions 200b and 200c and the side surface of the terminal body 104 should be such that the slide force can be applied only by a certain force. If the frictional force is excessively small, the cover part 200 slides even when it is not desired, which may cause inconvenience to the user.

More specifically, the side surface of the terminal body 104, that is, the convex portion 134 includes a first portion 131 which is inclined so as to be gradually moved downward from the front surface of the terminal body 104, And a second portion 132 that extends from the first end 131 and is inclined to approach the rear surface of the terminal body 104. That is, the side surface of the terminal body 104 is protruded (bent) toward the outside, and the first portion 131 and the second portion 132 are protruded from the side central portion 133 of the terminal body 104 It touches. It is not necessarily required to be vertically symmetrical throughout the entire side surface of the terminal body 104 and at least in the vicinity of the central portion 133 where the first portion 131 and the second portion 132 intersect. That is, it is sufficient if the intersection point of the first portion 131 and the second portion 132 is located at the side center portion 133 of the terminal body 104. Here, the center portion 133 of the side surface means a half of the thickness of the mobile terminal 100. This is because the cover unit 200 is mounted so as to cover the front surface of the mobile terminal 100 and can be mounted to cover the rear surface.

The side surface of the terminal body 104 is formed to be convex outward along the width direction D2 of the terminal body 104. The inside cover 210 and the outside cover 220 are formed on the side surface of the terminal body 104 And are spaced apart from each other at a side portion of the terminal body 104. [

The mobile terminal 100 is not separated by the side portions 200b and 200c. For this, the side portions 200b and 200c are formed to overlap with the first portion 131 or the second portion 132. 6, the side portions 200b and 200c are connected to the second portion 132 and the second portion 132, respectively, when the cover portion 200 is mounted to cover the front surface of the terminal body 104. [ The side portions 200b and 200c are overlapped with the first portion 131 as shown in FIG. 7 when the cover portion 200 is mounted so as to cover the rear surface of the terminal body 104 . At this time, a portion of the side portions 200b and 200c that does not overlap with the terminal body 104 is spaced apart from the terminal body 104 by a predetermined gap G1. This is to minimize the contact between the terminal body 104 and the cover part 200 when the cover part 200 and the terminal body 104 move relative to each other (slide movement).

At this time, the inclined angle? Of the first portion 131 and the second portion 132 may be a problem. If the angle between the front surface S1 of the terminal body 104 and the extended surface S2 of the first portion 131 or the second portion 132 is less than 10 degrees, The cover portion 200 can be separated from the mobile terminal 100 by a small force and if the cover portion 200 is larger than 20 degrees, the frictional force between the cover portion 200 and the terminal body 104 increases, The first part 131 and the second part 132 and the front surface of the terminal body 104 are 10 to 20 degrees from the plane perpendicular to the front surface of the terminal body 104. [ However, this may vary depending on the material of the cover part 200 and the terminal body 104, and is not necessarily limited to this angle. For example, when the inner cover 210 is made of a rubber material and the terminal body 104 is made of polycarbonate, the frictional force is higher than that of the inner cover 210 and the terminal body 104 when the terminal body 104 is made of polycarbonate. The first portion 131 and the second portion 132 may be formed to be more steep than the front surface of the terminal body 104. [ That is, there may be a case where the inclination angle? Is 10 degrees or less.

In an embodiment of the present invention, a sensor for sensing a magnetic change is used to sense a relative movement between the cover unit 200 and the mobile terminal 100. That is, a hall sensor 270 (Hall Sensor, Hall IC) is used to sense a magnetic or magnetic member 260 of a point or a linear shape and a magnetic change of the magnetic member 260. The driving principle of the Hall sensor 270 is It will be apparent to those skilled in the art that the invention is not limited to the specific details.

A magnetic member 260 is provided between the inner cover 210 and the outer cover 220 and a hall sensor 270 for detecting a magnetic change is provided inside the mobile terminal 100, And the magnetic member 260 is disposed in the receiving groove 216 formed in the inner cover 210. The magnetic member 260 is disposed in the receiving groove 216 formed in the inner cover 210. [ The receiving groove 216 does not necessarily have to be formed on the inner cover 210 but may be formed on the outer cover 220 and the inner cover 210 and the outer cover 220 may have a magnetic member 260 ) Can be accommodated. In the following description, the receiving groove 216 is formed on the inner cover 210. [

6A and 7A, since the receiving groove 216 is formed in the inner cover 210 and the magnetic member 260 is inserted into the receiving groove 216, The formed portion protrudes from the other portion.

Since the window 151a is recessed more than the front case 101 even if the receiving groove 216 is formed so that the cover 200 covers the front surface of the terminal body 104, When the cover 200 is mounted so as to cover the rear surface of the terminal body 104 as shown in FIGS. 7B and 7C, the cover 200 may be attached to the terminal body 104 More specifically, the rear cover 103). However, if the rear cover 103 is formed as a flat surface, the cover part 200 may slide without being in contact with the cover part 200, or may move while finely contacting. However, when the rear cover 103 is formed to be convex toward the outside as shown in FIG. 7, scratches may be generated on the rear cover 103 when the cover portion 200 is slid. In an embodiment of the present invention, a predetermined pattern is formed on the outer surface of the rear cover 103 to prevent the occurrence of the scratches. The pattern may be formed in a plurality of directions in the horizontal and vertical directions or in a diagonal direction of the rear cover 103. It is sufficient that the outer surface of the rear cover 103 is not flat.

The inner cover 210 and the outer cover 220 are spaced apart from each other by a predetermined gap G2. The reason for separating the inner cover 210 and the outer cover 220 from each other is that the terminal body 104 The cover portion 200 is easily detached and attached even when the dimensions of the cover portion 103 are changed. That is, the gap G2 is generated due to the overlap between the mobile terminal 100 and the side portions 200b and 200c, thereby providing a space in which the inner cover 210 can move finely with tension .

The inner cover 210 and the side covers 200b and 200c of the outer cover 220 are spaced apart from each other so that the cover 200 can be easily detached and attached in the thickness direction of the terminal body 104. [ The cover unit 200 may slide on the terminal body 104 to separate the cover unit 200 from the terminal body 104 and may be detachably attached to the mobile terminal 100 in the thickness direction. If the space for the inner cover 210 to flow through is not provided when the cover unit 200 is detached and attached in the thickness direction, the cover unit 200 must be mounted on the terminal body 104 in a forced fit manner. In the same case, since the scratches may occur on the side surface of the terminal body 104, the side cover parts 200b and 200c of the inner cover 210 and the outer cover 220 are separated from each other.

At this time, the inner cover 210 is not exposed to the outside of the outer cover 220. A bent portion 221 is formed at the ends of the side portions 200b and 200c of the outer cover 220 so that the ends of the side portions 200b and 200c of the inner cover 210, And the portion 211 exposed to the outside can be accommodated in the bent portion 221. The inner cover 210 may be attached to the terminal body 104 in the thickness direction when the end 211 of the inner cover 210 is exposed to the outside of the outer cover 220. [ The flowable space of the flow channel becomes narrow.

The inner cover 210 and the outer cover 220 are coupled by an adhesive, ultrasonic welding, adhesive tape, bonding, or the like. As described above, the side cover 200b And 200c, the inner cover 210 and the outer cover 220 are spaced apart from each other. When the coupling force (adhesive force) between the inner cover 210 and the outer cover 220 is weakened, the outer cover 220 and the inner cover 210 may move relative to each other. One or more through holes 214 may be formed in the side portions 200b and 200c of the inner cover 210 to prevent this from occurring and the outer cover 220 may include one or more protrusions 224 So that the protrusion 224 is inserted and fixed in the through hole 214.

8, a plurality of through holes 214 are formed in the side portions 200b and 200c of the inner cover 210. Through the through holes 214, (224) is inserted. However, the degree of protrusion of the protrusion 224 is so small that it does not protrude from the inner cover 210. This is because if the protrusion 224 protrudes from the inner cover 210, the cover body 200 can generate scratches on the terminal body 104 when the cover unit 200 is coupled to the terminal body 104.

A plurality of grooves 215 are formed in the front portion 200a of the inner cover 210 so as to easily adjust the position when the outer cover 220 is engaged with the inner cover 210. [ That is, the outer cover 220 is formed with a fine protrusion 225 at a portion corresponding to the groove 215 of the inner cover 210, and the protrusion 225 is fitted into the groove 215, The cover 210 and the outer cover 220 can be easily coupled. At the same time, the inner cover 210 and the outer cover 220 can be prevented from being twisted.

When the cover unit 200 slides to the end on the terminal body 104 and can no longer move relative to the cover unit 200, the cover unit 200 is maintained on the mobile terminal 100 without sliding on the mobile terminal 100 It is necessary. A stopper 217 protruding from the lower ends of the side portions 200b and 200c of the inner cover 210 is formed and a stopper receiving groove 117 formed in a side surface of the terminal body 104 is formed have. A cutting line 212 surrounding the stopper 217 is formed at an adjacent portion of the stopper 217. 9, the stopper 217 protrudes inwardly from the side portions 200b and 200c of the inner cover 210, and the stopper 217 protrudes inward of the terminal body 104 when the slide is moved. That is, And moves in contact with the side surface. When the stopper 217 moves to the stopper receiving groove 117 during the slide movement, the stopper 217 is seated in the stopper receiving groove 117. At this time, when the slide is moved, the portion of the inner cover 210 where the stopper 217 is formed is bent away from the terminal body 104. A certain portion inner cover 210 is cut around the stopper 217 by a cutting line 212 so that the portion where the stopper 217 is formed can be easily bent.

The cover part 200 is formed with a receiving part 200d so as to cover the upper or lower end of the mobile terminal 100 when the mobile terminal 100 is mounted to the mobile terminal 100, (218) may be formed. When the stopper 218 is formed on the receiving portion 200d, a groove (not shown) similar to the stopper receiving groove 117 is formed on the upper surface or the lower surface of the terminal body 104. [ The stopper 118 functions to prevent the cover unit 200 from being detached in the thickness direction of the mobile terminal 100. The receiving portion 200d is partially cut through the receiving portion 200d so that the microphone 122 or the charging cable can pass through the receiving portion 200d.

10 is a front view of a mobile terminal 100 equipped with a cover part 200 formed with fine holes 205 according to an embodiment of the present invention. Fig. 11B is a cross-sectional view of a diffuser sheet 230 according to an embodiment of the present invention.

Hereinafter, description will be made with reference to FIGS. 10 to 11. FIG.

The outer cover 220 may be transparent or translucent and the fine holes 205 may be formed as dots and various patterns may be formed on the outer side of the fine holes 205 through the fine holes 205. [ Can be displayed. For example, as shown in FIG. 10A, time information can be displayed through the fine holes 205. Also, as shown in FIG. 10B, the fine holes 205 may be formed only in a part of the cover part 200.

A diffusion sheet 230 is disposed between the inner cover 210 and the outer cover 220 so that light is transmitted to the outside through the window 151a. A brightness enhancement film 231, a light concentrating film 232, a diffuser film 133 and a light guide plate 234 (light guide plate, LGP).

The brightness enhancement film 231, the light concentrating film 232, the diffusion film 233, and the light guide plate 234 may be stacked in this order as shown in FIG. 11B, but the present invention is not limited thereto. It goes without saying that the configuration may be omitted or added. The diffusion sheet 230 may function to transmit light generated from the LCD module 151b.

At this time, a filling member 236 is formed in the lower part of the outer cover 220 to fill a part of the fine holes 205. It is possible to prevent foreign matter from entering from the outside through the fine holes 205 by the filling member 236 and to protect the internal materials such as the diffusion sheet 230. Further, it prevents the strong light from being diverted to the outside, and also performs the function of emitting the soft light to the outside. A filler 235 is formed in the fine holes 205. The filling member 236 may be made of a polycarbonate material or a polyoxymethylene (POM) material. At this time, the inner cover 210 uses a transparent or translucent material.

13 and 14 are views for explaining a touch input according to an embodiment of the present invention. According to an embodiment of the present invention, a touch sheet 240, for example, may be interposed between the inner cover 210 and the outer cover 220, a conductive pad 250 is provided between the inner cover 210 and the window 151a or a gap between the window 151a and the inner cover 210 is set to 0.3 mm or less , And a touch sheet may be provided inside the window 151a. Fig. 13 is a diagram for the former, and Fig. 14 is a diagram for the latter.

Referring to FIG. 13, the front portion 200a of the cover portion 200 is spaced apart from the terminal body 104, and the touch sensitivity is reduced when the cover portion 200 is touched from the outside due to the spacing distance. In order to compensate for this, the conductive pad 250 is disposed between the cover portion 200 and the window 151a. One side of the conductive pad 250 is in contact with the window 151a and the other side of the conductive pad 250 is in contact with the touch sheet 240 through a part of the inner cover 210. The touch sheet 240 includes an ITO film and an electrode. Since the touch sheet 240 is obvious to those skilled in the art, a detailed description thereof will be omitted.

The gap between the cover part 200 and the window 151a described above is spaced apart by about 1.7 mm. Since the touch sensitivity is low in such a spacing distance, the touch sensitivity can be improved by minimizing the spacing distance. For example, by setting the air gap between the inner cover 210 and the window 151a to 0.3 mm or less, even if the cover unit 200 is touched, the touch window 151a Input becomes possible. 14 shows a case where fine holes 205 are formed in the outer cover 220. The filling member 236 is disposed at the lower portion of the outer cover 220 and the filling portion 235 And may be formed in the fine holes 205.

One embodiment of the present invention is also applicable to the mobile terminal 100 having the rear input unit 280. The back side of the mobile terminal 100 generally includes a flash 124, A rear input unit 280 is provided. Furthermore, there is a case where a laser detection auto focusing (LDAF) is arranged. When the cover unit 200 is mounted to cover the rear surface of the terminal body 104, care must be taken not to cover the components. For this purpose, the components are arranged at the upper end of the rear surface of the mobile terminal 100 according to an embodiment of the present invention. For this purpose, the flash of the mobile terminal 100 and the laser detection auto focusing (LDAF) may be integrally formed and modularized.

15 is a schematic exploded perspective view of a rear cover 103 according to an embodiment of the present invention. As shown in FIG. 15, a rear input unit 280 is disposed at the upper center of the rear surface of the mobile terminal 100, An integrated module 124 'of a flash and an autofocus device may be disposed on one side of the rear input unit 280 and a camera 121 may be disposed on the other side of the rear input unit 280. However, this is merely an example, and it is sufficient that the cover 121 is disposed so that the camera 121, the rear input unit 280, and the module 124 'are not covered when the cover unit 200 is slid. (For example, a portion corresponding to R1 in Fig. 4) that is not covered by the cover portion 200. [0064]

The autofocusing apparatus measures a distance using a laser. The autofocusing apparatus includes a light-emitting unit that transmits a laser and a light-receiving unit that receives a laser. The distance is measured using the phase difference between the transmitted output signal and the received signal. And automatically adjusts the focus when taking pictures or movies.

That is, in the conventional auto focusing system (AF), it takes time to focus on the entire image by focusing on the image without using a laser. However, the autofocus apparatus measures the distance from 0 to 50 cm It is processed quickly by laser, otherwise it is processed by conventional AF method.

In an exemplary embodiment of the present invention, a terminal body 104 having a display unit 151, a cover unit 200 configured to cover at least a part of the display unit 151, a display unit 151 A sensing unit 140 sensing a relative movement of the cover unit 200 relative to the cover unit 200 and a controller 180 performing a predetermined function based on the stepwise movement of the cover unit 200. [ A terminal assembly may be provided. The control unit 180 controls the display unit 151 to display information on the predetermined function by the stepwise movement of the cover unit 200 in an exposed area that is not covered by the cover unit 200, And controls the display unit 151 to output the output signal. The sensing unit 140 senses whether or not the cover unit 200 is being slid or moved. For example, the sensing unit 140 may be a Hall sensor (270), and is installed inside the mobile terminal 100 to detect movement of the cover unit 200.

That is, the sensing unit 270 may be a Hall sensor 270 that senses a change in magneticity of the magnetic member 260 described above.

In an embodiment of the present invention, the cover unit 200 may be formed in a plurality of systems. When the cover units 200 of the same system are positioned adjacent to each other, the cover unit 200 may be sensed and notified. The rear cover 103 or the cover 200 may be provided with an identification module 245 for identifying whether the cover 200 is the same or not. Is provided with an antenna 281 capable of communicating with another adjacent terminal. The antenna 281 may be, for example, an NFC antenna 281, disposed inside the rear cover 103, or disposed between the inner cover 210 and the outer cover 220. The inner cover 210 and the outer cover 220 can be joined by an adhesive, bonding or the like, and therefore, it is advantageous to be disposed inside the rear cover 103. At this time, a battery sheet 282 is provided outside the antenna 281, and the identification module 245 may be a chip.

When the mobile terminal assemblies having the same or different series of cover units 200 are positioned adjacent to each other, the display unit 151 of the mobile terminal 100 displays the mobile terminal assemblies or the alarm unit 154 It is possible to inform that the cover part 200 of the same or different series is near by using voice or vibration.

For example, if three mobile terminals 100a, 100b, and 100c have the same series of cover units 200 as shown in FIG. 17, a greeting message may be displayed on the display unit 151, Or vibration to the user. For example, the cover unit 200 may be the same color as the cover unit 200, and may be a case where the images Ha, Hb, and Hc displayed on the display unit 151 are the same character have. This is merely an example, and it is possible to set the cover part 200 to be the same series by various combinations (image, color, facial expression, etc.).

The magnetic member 260 may be disposed in one or more receiving grooves 216 formed along the sliding direction of the cover unit 200 and may include two or more sensors 270, 271, 272, and 273 for detecting the magnetic change . If two or more sensors are disposed, the step of detecting the movement of the magnetic member 260 can be divided into two or more steps. By using this, it is possible to divide the exposure region into two or more stages, and thereby, when an event is generated, it can be executed step by step. At this time, the magnetic member 260 may be one or a plurality of magnetic members 260. If the magnetic member 260 is a plurality of magnetic members 260, magnetic forces of the magnetic members 260 may be different from each other. Since the plurality of magnetic members 260 having different magnetic forces are disposed at a plurality of positions as described above, the position of the magnetic member 260 sensed by the sensors 271, 272, and 273 can be more clearly detected, Can be detected more clearly.

As described above, when the plurality of sensors 270 are used, the relative movement of the cover unit 200 and the mobile terminal 100 can be divided into various stages, .

This will be described with reference to FIG.

As shown in FIG. 4A, a state in which the cover unit 200 is mounted on the mobile terminal 100 and completes the slide movement upwardly is referred to as a first state, and as shown in FIG. 4B, The cover unit 200 is moved downward in the first state and the second state is the state in which the cover unit 200 is not separated from the mobile terminal 100. In the second state, A case where the mobile terminal 100 is moved downward to the end and separated from the mobile terminal 100 can be referred to as a third state. However, this is merely an example, and it is possible to pass the cover unit 200 from the state in which the cover unit 200 is moved to the upper end to the state in which the cover unit 200 is separated from the mobile terminal 100 in three or more steps.

The area of the display unit 151 exposed in the first state is referred to as a first exposure area R1 and the area of the display unit 151 exposed in the second state is referred to as a second exposure area R2 , And the area of the display unit 151 exposed in the third state will be referred to as a third exposure area R3.

The plurality of steps may vary according to the number of the sensors 270 that are located at different positions. If the number of sensors is n, (n + 1) exposure regions can be realized. However, in FIG. 4, three exposure areas R1, R2, and R3 are implemented by three sensors 271, 272, 273.

4A to 4C, the magnetic member 260 is linearly formed in the longitudinal direction of the mobile terminal 100, and the magnetic member 260 is formed on the moving path of the magnetic member 260 The first sensor 271, the second sensor 272, and the third sensor 273 are disposed, respectively. In the first state, the first to third sensors 271, 272, and 273 detect the magnetic member 260 to realize the first exposed region R1. In the second state, only the third sensor 273 detects the magnetic member 260, And senses the second exposure region 260 to implement the second exposure region R2. Also, in the third state, the magnetic member 260 is not sensed at any of the first to third sensors 271, 272, 273, thereby realizing the third exposed region R3.

4, the magnetic member 260 is elongated in the longitudinal direction of the mobile terminal 100. However, the present invention is not limited thereto, and the magnetic member 260 may be formed in a dot shape . This will be described with reference to FIG.

12 is a schematic plan view of a mobile terminal assembly in a state where the cover unit 200 is coupled to the mobile terminal 100 according to an embodiment of the present invention.

12, the magnetic members 261 are arranged in the form of dots and the first to third sensors 271, 272 and 273 are provided inside the mobile terminal 100 along the sliding direction of the cover unit 200 . 12A shows a first state in which the cover unit 200 completes the slide movement upwardly on the mobile terminal 100. The magnetic member 261 is sensed by the first sensor 271, 12B shows a state in which the cover member 200 is slid downward in the first state to detect the magnetic member 261 in the second sensor 272 Showing the second state, and the second exposed region R2 'is realized.

12C shows a third state in which the third sensor 273 senses the magnetic member 261 by sliding the cover unit 200 further downward in the second state, 12D shows a fourth state in which the cover unit 200 is detached from the mobile terminal 100, and a fourth exposure region R 4 is realized Respectively.

The first to fourth exposure areas in Figs. 4 and 12 are merely the order as the exposure areas increase, so that the " first "to " third" exposure areas in Figs. no.

When the sensors 271, 272 and 273 are arranged in the movement path of the magnetic members 260 and 261, the first exposed regions R1 and R1 ', the second exposed regions R2 and R2' R3 ') and, in some cases, a fourth exposure region R4 may also be implemented. The exposure area of the display unit 151 changes according to the change from the first exposure area R1 to the third exposure area R3 so that additional functions can be performed in stages.

FIGS. 20 to 22 are diagrams for explaining a step-by-step function according to an exemplary embodiment of the present invention. In the first to second exposure regions R1 and R2 described above, . For example, as shown in FIG. 20A, when a message is received, a message arrival notification window is displayed in the first exposure area R1, and when the user wants to view a more specific content, The detailed contents of the message arrival notification and the message are displayed in the second exposure area R2. Similarly, as shown in FIG. 21A, when a voice call signal arrives, summary information on the caller is displayed in the first exposure area R1, and more detailed information (for example, photograph) about the caller is displayed 21B, the cover unit 200 is slid downward so that specific information about the caller is displayed in the second exposure area R2.

At this time, FIG. 21C shows that the cover unit 200 is slid downward without going through steps, and immediately enters into the talk mode. In this manner, when the call signal is received, if the cover unit 200 is slid without moving through the steps, the user can immediately enter the talk mode.

This also applies to the case of SNS (Social Network Service) as shown in FIG. That is, as shown in FIG. 22A, when a message is received, brief information of the caller is received in the first exposure area R1, and the cover unit 200 is slid downward as shown in FIG. 22B More detailed contents can be displayed in accordance with the contents of the message.

In this case, when the movement of the cover unit 200 is detected in the state where the event is generated in the mobile terminal 100, the controller 180 controls the movement of the cover unit 200 and the movement of the cover unit 200, And performs a function related to the event in the at least one exposure area. In addition, when the cover unit 200 is moved in a state where the event is generated to expose the entire surface of the display, a function related to the event may be performed over the entire exposed region. 20 to 22, only the first and second exposure regions R1 and R2 are displayed. However, as shown in FIG. 12, the control unit 180 controls the first to fourth exposure regions R1 ' , R2 ', R3', and R4.

The display unit 151 is divided into one or more exposed regions by the relative movement of the cover unit 200 with respect to the display unit 151 and the exposed regions include images H1, H2, H3) may be displayed. The images H1, H2, and H3 may be part or all of the character. Thus, by displaying the images H1, H2, and H3 in the exposure area, the user can enjoy the enjoyment.

At this time, various images can be expressed using the image H1. For example, as shown in FIG. 16, an angry expression H11, a pleasant expression H12, a sad expression H13, H14) and so on. When the cover unit 200 is mounted on the mobile terminal 100 and is displayed only in the first exposure area R1, if the cover unit 200 of the same series is located adjacent to the cover unit 200, And may be changed to the angry expression H11 when the cover part 200 of another system is located. In addition, not only the expression of the image but also the sound or vibration of the alarm part 154 may be used to inform that the cover part 200 of the same series or another series is nearby.

In addition, the image may indicate the state of charge of the terminal. If the state of charge of the mobile terminal 100 is, for example, 50% or less, the image H1 may be tired So that the state of charge can be predicted. At this time, the image (H1) color, concentration and the like may be different depending on the state of charge.

In an embodiment of the present invention, the cover unit 200 covers the display unit 151 in a first direction, and the cover unit 200 covers the display unit 150 in a second direction different from the first direction. When covering the portion 151, a new event can be generated. In this case, the first direction means upward and the second direction means downward. As described above, by sliding the cover unit 200 upward or downward, an event can be performed or terminated.
