1 to 3 are conceptual diagrams for explaining a terminal set 10 related to the present invention. 1 shows a state before a mobile terminal 100 is coupled to an auxiliary device 200 in a terminal set 10 related to the present invention, and FIG. 2 illustrates a state in which the mobile terminal 100 is coupled to the auxiliary device 200. 3 is a diagram illustrating a state in which the folio cover 260 of the auxiliary device 200 is separated from the state of FIG. 2. 1 to 3 are referred to together for better understanding.

The terminal set 10 of the present invention includes a mobile terminal 100 having a display and an auxiliary device 200 that is combined with the mobile terminal 100 to provide an extended display. The auxiliary device 200 is again coupled to the terminal case 210 and the terminal case 210, which is an area where the mobile terminal 100 is coupled, selectively covering the mobile terminal 100, and a folio cover for mounting an extended display ( 260).

As described above, in the terminal set 10 of the present invention, the mobile terminal 100 and the auxiliary device 200 each form an output area to provide a multi-display, thereby increasing usability. A display provided in the mobile terminal 100 is defined as a first display 151 and a display provided in the auxiliary device 200 is defined as a second display 261.

The first display 151 and the second display 261 may be output in connection with each other. For example, the first display 151 and the second display 261 may be mirrored and output, or a screen output on the first display 151 may be moved to the second display 261 and output, or An execution screen of one application or a plurality of linked applications may be divided and output on the two displays 151 and 261. For example, the controller of the game application may output the game content to the first display 151 and the second display 261. That is, the terminal set 10 of the present invention can operate like a single device having a plurality of displays, which means that the auxiliary device 200 shares several configurations of the mobile terminal 100.

More specifically, the controller 180 and the power supply unit 190 of the mobile terminal 100 may supply power to the second display 261 as well as the first display 151 and transmit and receive data. Therefore, the auxiliary device 200 can operate without a separate control unit 180 or a power supply unit 190. This can reduce the weight or volume of the auxiliary device 200, and can achieve a manufacturing cost reduction effect.

In order to supply power to the second display 261 and transmit and receive data, the mobile terminal 100 is physically coupled to the auxiliary device 200, and the auxiliary device 200 includes the mobile terminal 100 and the second display 261. It has a circuit for electrically connecting the.

Conventionally, in order to transmit and receive data between the mobile terminal 100 and the auxiliary device 200, the mobile terminal 100 had to additionally include a separate terminal or a wireless communication chip. However, these configurations are unnecessary for self-driving the mobile terminal 100 and increase the volume, weight, and manufacturing cost of the mobile terminal 100. In order to solve these shortcomings, the terminal set 10 of the present invention proposes a method of transmitting and receiving data and supplying power through a charging port 161 that is essentially provided in the mobile terminal 100. Details of this will be described later.

In addition, in order to compensate for the disadvantages of the auxiliary device 200 in which the folio cover 260 and the terminal case 210 are integrally provided, the auxiliary device 200 of the present invention includes the folio cover 260 in the terminal case ( 210). Advantages of the auxiliary device 200 having the detachable folio cover 260 are as follows.

First, when the folio cover 260 is not used, only the terminal case 210 is coupled to the mobile terminal 100 to obtain a function of physically protecting the mobile terminal 100. In the conventional case where the folio cover 260 is always fixed to the terminal case 210, the folio cover 260 must be used in a state of large volume and weight even though the folio cover 260 is not used, and the grip feeling of the mobile terminal 100 is reduced. Let it. Therefore, by combining only the terminal case 210 to the mobile terminal 100, this disadvantage can be compensated.

Second, the detachable folio cover 260 may be continuously used even if the mobile terminal 100 and the terminal case 210 are replaced. For example, even if the terminal case 210 used in conjunction with a specific mobile terminal 100 is damaged or lost, only the terminal case 210 can be replaced and the folio cover 260 used in the past can be used as it is.

Third, even when a mobile terminal 100 and a terminal case 210 having different shapes or sizes from the existing mobile terminal 100 are used, the folio cover 260 used in the past may be combined and used. Of course, this assumes that the mobile terminal 100 and the terminal case 210 having different shapes or sizes are configured to be compatible with the existing folio cover 260.

As an example, when the user holds the terminal body with one hand, the rear input unit may be disposed on the rear upper end of the terminal body so that the user can easily manipulate the terminal body using the index finger. However, the present invention is not necessarily limited thereto, and the position of the rear input unit may be changed.

When the rear input unit is provided on the rear surface of the terminal body, a new type of user interface can be implemented using the rear input unit. In addition, when the touch screen or the rear input unit described above replaces at least some functions of the first operation unit 123a provided on the front of the terminal body, and the first operation unit 123a is not disposed on the front of the terminal body, The display unit 151 may be configured with a larger screen.

Meanwhile, the mobile terminal 100 may be provided with a fingerprint recognition sensor for recognizing a user's fingerprint, and the controller 180 may use fingerprint information detected through the fingerprint recognition sensor as an authentication means. The fingerprint recognition sensor may be embedded in the display unit 151 or the user input unit 123.

The microphone 122 is configured to receive a user's voice and other sounds. The microphone 122 may be provided in a plurality of locations and configured to receive stereo sound.

For example, the interface unit 160 is a connection terminal for connection with other devices (eg, earphones, external speakers), a port for short-range communication (eg, an infrared port (IrDA Port), a Bluetooth port (Bluetooth Port), a wireless LAN port, etc.], or at least one of a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card such as a subscriber identification module (SIM) or a user identity module (UIM), or a memory card for storing information.

A second camera 121b may be disposed on the rear surface of the terminal body. In this case, the second camera 121b has a photographing direction substantially opposite to that of the first camera 121a.

The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may be arranged in a matrix format. Such a camera may be referred to as an'array camera'. When the second camera 121b is configured as an array camera, an image may be photographed in various ways using a plurality of lenses, and an image of better quality may be obtained.

The flash 124 may be disposed adjacent to the second camera 121b. The flash 124 illuminates light toward the subject when photographing the subject with the second camera 121b.

At least one antenna for wireless communication may be provided in the terminal body. The antenna may be embedded in the terminal body or may be formed in a case. For example, an antenna forming a part of the broadcast reception module 111 (refer to FIG. 4) may be configured to be retractable from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

It is illustrated. When the battery 191 is configured to be detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

6 is a block diagram illustrating a terminal set 10 related to the present invention.

As described above, the terminal set 10 of the present invention is divided into a mobile terminal 100 and an auxiliary device 200, and the auxiliary device 200 includes a terminal case 210 and a folio cover 260 again. A first display 151 is provided on the mobile terminal 100 and a second display 261 is provided on the folio cover 260.

The controller 180 is provided in the mobile terminal 100 and controls the operations of the first display 151 and the second display 261. That is, the controller 180 controls the overall operation of the mobile terminal 100 as described with reference to FIG. 4, and in addition to this, also controls the operation related to the output of the second display 261. The controller 180 may include an application processor (AP) or a system-on-chip (SOC) physical form, and is mounted on the mobile terminal 100.

The memory 170 provided in the mobile terminal 100 may be used for the operation of the first display 151 and furthermore the second display 261. For example, a game application stored in the memory 170 of the mobile terminal 100 is driven by signal processing and calculation of the controller 180, and data for screen output is output to the first display 151 or an auxiliary device. It may be transmitted to 200 and output to the second display 261.

The power supply unit 190 of the mobile terminal 100 may supply power for the operation of the auxiliary device 200 as well as the operation of the internal configuration of the mobile terminal 100. The auxiliary device 200 may include a switch 211 for selectively supplying power. In particular, the switch 211 may be provided on the terminal case 210 side.

That is, the second display 261 of the auxiliary device 200 may be driven depending on the application processor, the memory 170 and the power supply unit 190 of the mobile terminal 100.

However, if necessary, a volatile memory for temporarily storing data, a small power supply unit, etc. may be provided, so that it may be used auxiliary for operation control.

In particular, the folio cover 260 may be provided with a second display controller 262 for controlling the output of the second display 261. The second display control unit 262 may convert data received from the mobile terminal 100 and output it to the second display 261 or perform other auxiliary tasks necessary for outputting the second display 261.

Furthermore, the auxiliary device 200 may include a touch panel corresponding to the second display 261 to generate, process, and transmit an input signal through the touch panel.

In addition, the auxiliary device 200 and the mobile terminal 100 are provided with a magnet and a hall sensor for sensing mutual coupling, and a user interface for starting interworking with the second display 261 May be output to the first display 151 or power supply to the second display 261 may be started.

The auxiliary device 200 and the mobile terminal 100 are electrically connected to supply power and transmit/receive data. More specifically, the second display 261 of the folio cover 260 is electrically connected to the mobile terminal 100 to receive power and transmit and receive data. The terminal case 210 serves to electrically connect both components between the folio cover 260 and the mobile terminal 100.

A circuit configuration provided in the folio cover 260 for driving the second display 261 is defined as a cover circuit unit 270, and a circuit configuration provided in the terminal case 210 is defined as a case circuit unit 220.

The folio cover 260 and the terminal case 210 may each have coupling terminals 271 and 221 to connect the cover circuit part 270 and the case circuit part 220. For classification, the former is defined as a cover-side coupling terminal 271 and the latter as a case-side coupling terminal 221. The charging port 161 of the mobile terminal 100 may be connected to the terminal coupling terminal 223 of the terminal case 210. Meanwhile, the terminal case 210 additionally has a cable coupling terminal 222 to separately provide a point where an external cable can be connected. Details will be described later.

In the following, features of the auxiliary device 200 will be described in more detail with reference to FIGS. 1 to 6 again.

The terminal case 210 forms a seating area 2101 on which the rear surface of the mobile terminal 100 is seated. When the mobile terminal 100 is seated, the terminal case 210 forms an output area of the display unit of the mobile terminal 100, that is, an open area so that the first display 151 can be visually recognized on the front side. At the same time, at least one area of the rear surface of the terminal case 210 also has an opening 2102 so that the camera part of the mobile terminal 100 is exposed. The side circumference 2103 of the terminal case 210 is formed to correspond to the lateral circumference shape of the mobile terminal 100 so that the mobile terminal 100 can be fitted to the terminal case 210 in a fit.

The folio cover 260 and the terminal case 210 of the auxiliary device 200 of the present invention are detachably coupled.

The folio cover 260 is coupled to the terminal case 210 and extends from one edge of the terminal case 210 to open and close the seating area 2101.

In order to implement the above feature, the folio cover 260 and the terminal case 210 may form a bonding area along the rear surface 2106 of the terminal case 210, particularly along one edge of the rear surface 2106. By forming the coupling region on the rear surface 2106 of the terminal case 210, it is possible to minimize an increase in the bezel region of the terminal set 10 compared to forming the coupling region on the side surface of the terminal case 210. Details of this will be described later.

The folio cover 260 provides the above-described second display 261 by mounting the display panel 2611. The display panel 2611 is exposed on one surface of the folio cover 260 to form an output area. The display panel 2611 may include a touch panel for receiving an external touch input.

7 is a bottom view of an embodiment of a terminal set 10 related to the present invention. 7(a) shows the folio cover 260 closed, and FIG. 7(b) shows the folio cover 260 opened. 1 to 3 will be referred to together for better understanding.

The folio cover 260 selectively opens and closes the seating area 2101 of the terminal case 210. That is, when the folio cover 260 is closed, the first display 151 of the mobile terminal 100 is covered and protected, and when the folio cover 260 is opened, the first display 151 and the folio cover of the mobile terminal 100 are opened. The second display 261 of 260 is visually recognized to the outside.

The folio cover 260 includes a plate-shaped coupling portion 263 coupled to the rear surface 2106 of the terminal case 210 and a rigid display case 264 for mounting a display panel 2611 implementing the second display 261. ) And a connection part 265 made of a flexible material connecting the coupling part 263 and the display case 264.

That is, the connection part 265 can be flexibly folded or unfolded due to the characteristics of the material, so that when the display case 264 is opened and closed, the connection part 263 and the connection state can be maintained. Since the connection part 265 does not play a role of maintaining the opening and closing angle of the display case 264 like a normal hinge, there are few restrictions on the material and shape. Therefore, the connection part 265 may be provided in the form of a fabric using a synthetic resin or a form of leather, and thus may be formed thin. Accordingly, the mobile terminal and the folio cover 260 may be unfolded at 180 degrees and placed on the floor, or may be unfolded at 360 degrees and used in a state where the folio cover 260 is overlapped on the rear surface of the mobile terminal.

In addition, as described above, when the coupling unit 263 is coupled to the rear surface 2106 of the terminal case 210, an increase in the bezel area of the terminal set 10 can be minimized. In particular, since the coupling portion 263 has a thin plate shape, an increase in the thickness of the terminal set 10 can also be minimized.

The terminal contact magnetic parts 281 (refer to FIG. 12) are provided on the corresponding surfaces of the folio cover 260 and the terminal case 210, respectively, to generate attractive force to each other. The terminal contact magnetic part 281 (refer to FIG. 12) assists the coupling of the hook protrusion and the protrusion groove to improve the coupling of the folio cover 260 and the terminal case 210 and contact reliability between the two contact terminals, and between the two members. It serves to guide the mating position. In order to achieve this purpose, it is preferable that the terminal contact magnetic part is provided in the vicinity of a region where the two coupling terminals 221 and 271 are in contact.

FIG. 8(a) is a front perspective view of a terminal case 210 related to the present invention, and FIG. 8(b) is a partial cross-sectional view of area A-A' of FIG. 8(a).

The coupling portion 263 may have a fastening structure for coupling the coupling portion 263 of the folio cover 260 and the rear surface 2106 of the terminal case 210. The coupling portion 263 may hook-couple both components, for example. As an example, the coupling part 263 has a hook protrusion 2631, and the rear surface 2106 of the terminal case 210 corresponding to the coupling part 263 has a protrusion groove 2107 so that both configurations can be selectively attached and detached. I can. When the coupling portion 263 is formed in the shape of a long plate in the longitudinal direction, the hook protrusion 2631 and the protrusion groove 2107 may be coupled to be distributed on both sides in the longitudinal direction. This is to increase the reliability of coupling between the coupling unit 263 and the terminal case 210.

The hook protrusion 2631 includes a rigid material, and the protrusion groove 2107 may be fitted to each other by a material of a mutual material including an elastic material. In order to prevent the increase in thickness, a method that does not include various components such as springs, buttons, etc. is adopted for the hook coupling, but in this case, in order to ensure the utmost reliability of coupling and separation, which can be relatively weak, rigid materials and It can be implemented by fastening of an elastic material. In particular, since the shape of the hook protrusion 2631 is more likely to be damaged, it is preferable that the hook protrusion 2631 is provided with a rigid material and the protrusion groove 2107 is provided with an elastic material. For example, the hook protrusion 2631 may be formed of a material such as metal or plastic. The protrusion groove 2107 may be formed of a material such as rubber.

The folio cover 260 having the connection part 265 made of a flexible material is inconvenient in that it cannot maintain a specific angle with the mobile terminal 100 unless it is placed on a separate support such as a floor surface to fix the display case 264. have. In order to solve this inconvenience, hereinafter, the angle between the first display 151 (display case 264) and the second display 261 (mobile terminal 100 coupled to the terminal case 210) is fixed. Look at the structure.

[Example 1]

FIG. 9(a) is a perspective view of a state before the display case 264 and the terminal case 210 are combined, and FIG. 9(b) is a partial cross-sectional view of area B-B' of FIG. 9(a).

The angle fixing protrusion 310 formed at the inner edge of the display case 264 is inserted into and coupled to the depression 320 formed in the other configuration, so that the angle between the display case 264 and the terminal case 210 may be fixed. The recessed portion 320 is formed to correspond to the shape of the angle-fixing protrusion 310 and fitted to fit, so that both components can be fixed without flow to each other.

The fixed angle between the display case 264 and the terminal case 210 varies depending on the design, but any one of 90 degrees or more and 180 degrees or less is appropriate in terms of user experience.

The combination of the angle-fixing protrusion 310 and the depression 320 is distributed on both sides based on the length direction of the edge of the mobile terminal 100, so that the flow occurs while the display case 264 is coupled to the terminal case 210. This minimizes the load and minimizes the possibility of damage due to the concentration of the load on the angle fixing protrusion 310 and the depression 320.

The angle-fixing protrusion 310 and the depression 320 can be easily combined, but in order to prevent unintentional separation after coupling, the angle fixing protrusion 310 may have a compressible hook 311 shape, and the depression The part 320 may have a pressing protrusion 321 that engages the hook 311 shape.

More specifically, the angle fixing protrusion 310 may include two hooks 311 forming a gap 312 to be compressed in a direction perpendicular to the insertion direction. That is, the two hooks 311 may have a fork shape. Meanwhile, the pressing protrusion 321 of the depression 320 may protrude in the compression direction so as to correspond to each boundary of the hooks 311. At this time, each end of the hook 311 may be formed with a chamfer 3111 so as to be easily pressed in the compression direction by a protrusion. That is, when the angle fixing protrusion 310 is inserted into the recessed part 320 for coupling, both the pressing protrusions 321 press the chamfer 3111 of each hook 311 so that both hooks 311 are compressed, When the hook 311 passes all of the pressing protrusions 321, both compressed hooks 311 are opened and fixed to the inner space of the pressing protrusion 321 of the depression 320.

The angle-fixing protrusion 310 may include a polyoxymethylene (POM) material in order to be easily deformed in shape and have durability even if there is repeated shape deformation. On the other hand, it is preferable that the concave portion 320, which is a counterpart of the angle-fixing protrusion 310, includes a material of rigidity, for example, polycarbonate, or a material such as metal, so that both components are not easily separated. .

FIG. 10(a) shows an embodiment of the display case 264 related to the present invention, and FIG. 10(b) shows the terminal case 210 of the same embodiment as that of FIG. 10(a).

As described above, the angle-fixing protrusion 310 and the depression 320 exhibit high coupling reliability as the mutual contact area increases. Accordingly, a method of increasing the number of angle-fixing protrusions 310 and depressions 320 or increasing the respective areas may be considered. In the present invention, the latter case is considered. In order to increase the area of the fixed protrusion 310 and the depression 320, the hook 311 may be extended in the lengthwise direction of the corner of the mobile terminal 100, but the hook 311 is an abnormal display case having a deformable POM material It is difficult to firmly maintain the fixing of 264 and the terminal case 210. Therefore, the angle fixing protrusion 310 may include an expansion rib 313 provided on at least one side of the hook 311, and the depression 320 may include a rib groove 322 corresponding to the expansion rib 313. have. In this case, the expansion rib 313 may be made of a rigid material, not an elastic material such as POM, so as to withstand a coupling load between the display case 264 and the terminal case 210. In particular, the expansion rib 313 may be formed in the same material as the display case 264. At this time, the expansion ribs 313 are formed to be expanded on both sides of the hook 311 to minimize the load applied to the hook 311.

The first embodiment has an advantage in that the angle of the display case 264 and the terminal case 210 can be fixed by supplementing the disadvantages of the connection part 265 made of a flexible material, but the depression 320 on the terminal case 210 Since the display case 264 is limited to the formed angle, there is a disadvantage that it cannot be fixed at various angles.

[Example 2]

FIG. 11(a) is a partial perspective view of a state before the display case 264 and the terminal case 210 are combined, and FIG. 11(b) is a view showing a state after the display case 264 and the terminal case 210 are combined. 11(a) is a cross-sectional view of the area CC' of FIG. 11(a), and FIG. 11(c) is a cross-sectional view of the area DD' of FIG.

In the second embodiment, similar to the first embodiment, the display case 264 is selectively coupled to the terminal case 210, but is coupled to the rotating member 213 rotated on the terminal case 210.

More specifically, the terminal case 210 of the present embodiment includes a support member 212 forming a seating area 2101 of the mobile terminal 100 and a rotating member 213 rotating with respect to the support member 212. Including, the display case 264 is coupled to the rotating member 213 to form a rotation angle depending on the rotation of the rotating member 213.

The rotating member 213 may include a free-stop hinge capable of fixing an angle when rotating with respect to the support member 212. The free-stop hinge 2131 generates a friction force so that the rotating member 213 and the display case 264 coupled to the rotating member 213 can be fixed to the support member 212 at a specific angle.

The rotation angle of the display case 264 may be limited by the adjacent boundary 2109 of the terminal case 210. It is preferable to ensure that the limited rotation angle of the display case 264 is 100 degrees or more and 180 degrees or less with respect to the terminal case 210. That is, in the terminal case 210, one adjacent boundary 2109a may be formed so that the display case 264 is folded up to 100 degrees or less, and the other adjacent boundary 2109b may be formed to be unfolded up to 180 degrees or more.

As in the first embodiment, the rotating member 213 and the display case 264 may be fixed through a combination of the angle fixing protrusion 310 and the depression 320, but the specific fastening method may be different. That is, as in the first embodiment, a hook coupling method may be adopted, or a slot 3201-magnet composite structure as shown in FIG. 11 may be used.

That is, the angle fixing protrusion 310 is provided in the shape of a protruding bar (bar 3101), and the depression 320 has a shape of a slot 3201 corresponding to the bar 3101. At the same time, an angle-fixed magnetic portion 330 for generating mutual attraction may be provided on a surface corresponding to the display case 264 and the terminal case 210. The attractive force of the angle-fixed magnetic portion 330 serves to guide the bar 3101 to be easily coupled to the slot 3201.

The configuration of the angle fixing protrusion 310 and the depression 320 of the second embodiment is also distributed and provided on both sides of the edge in the longitudinal direction as in the first embodiment to minimize the possibility of clearance of the display case 264 and achieve structural stability. I can. However, the pre-stop hinge 2131 may be provided only on one side.

12(a) is a perspective view before the folio cover 260 and the terminal case 210 of the auxiliary device 200 related to the present invention are combined, and FIG. 12(b) is a rear view of the terminal case 210 related to the present invention. (2106) It is a perspective view.

The cover circuit part 270 of the folio cover 260 may be formed over the display case 264, the connection part 265, and the coupling part 263. That is, the connection part 265 may include a wiring 272 connecting the second display 261 and the cover-side contact terminal. Since the connection part 265 has a flexible material, the wiring 272 is preferably provided with a flexible PCB, and for the same reason, a chipset such as the control unit of the second display 261 of the cover circuit part 270 is a display case It is implemented in (264).

Each contact terminal is provided on the opposite surface of the coupling part 263 and the terminal case 210 to face each other. When the coupling portion 263 is coupled to the terminal case 210, the two contact terminals also contact each other, so that the folio cover 260 and the terminal case 210 are electrically connected.

13(a) is a front view of a partial area of the terminal set 10 related to the present invention before the mobile terminal 100 is combined, and FIG. 13(b) is a mobile terminal 100 of the terminal set 10 related to the present invention. It is a front perspective view of some areas after bonding.

As described above, in order to minimize an increase in the volume and manufacturing cost of the terminal set 10, the auxiliary device 200 is a terminal coupling terminal 223 that is coupled with a charging port 161 that is essentially provided in the mobile terminal 100. ) Can have the form. Since the charging port 161 provided as an essential component of the mobile terminal 100 has a power pin and a data pin, both power supply and data transmission and reception are possible only by connecting the charging port 161 and the terminal coupling terminal 223. .

A typical form of the charging port 161 may be a USB-C type terminal, but is not limited thereto, and any type of a power pin and a data pin may be used.

The terminal coupling terminal 223 may have a shape and a pin corresponding to the charging port 161. Therefore, when the charging port 161 is a USB-C type terminal, the terminal coupling terminal 223 is also provided in the form of a USB-C type terminal.

The cable coupling terminal 222 is provided in the auxiliary device 200 so that the terminal coupling terminal 223 can be connected from the external cable 401 even when the terminal coupling terminal 223 is coupled to the mobile terminal 100. The cable coupling terminal 222 is electrically connected to the terminal coupling terminal 223 and the charging port 161 to supply power to the terminal set 10 from the outside or perform data transmission/reception with the outside. The cable coupling terminal 222 may include a data pin and a power pin in the same manner as the terminal coupling terminal 223.

The cable coupling terminal 222 may be provided in a form in which the terminal 402 of the cable 401 is inserted and fixed, but the magnet 403 in which the connection state of the two terminals 222 and 402 is maintained by magnetic force. It may be provided in a combination manner. The magnet 403 coupling method has an advantage that the possibility of damage to the terminal can be reduced, and the cable and the cable coupling terminal can be easily connected or separated.

FIG. 14(a) shows a partial area of the terminal set 10 related to the present invention, and FIG. 14(b) is a cross-sectional view of FIG. 14(a) in the direction E-E'.

When the direction in which the auxiliary device 200 of the mobile terminal 100 is seated and the direction in which the terminal coupling terminal 223 is inserted are vertical, the mobile terminal 100 is mounted on the terminal case 210 and the terminal coupling terminal 223 It can be difficult to combine. To solve this, the auxiliary device 200 of the present invention may provide a rotation axis to the terminal case 210 so that the terminal coupling terminal 223 can be tilted outside the seating area 2101. That is, an area of the terminal case 210 may include a terminal rotating member 2105 capable of rotating with respect to the seating area 2101 while mounting the terminal coupling terminal 223.

When the mobile terminal 100 is fastened to the terminal coupling terminal 223 and coupled to the seating area 2101, the terminal rotating member 2105 has the same shape as the outer boundary of the terminal case 210 so that there is no foreign body feeling. Can be implemented.

It is obvious to a person skilled in the art that the present invention can be embodied in other specific forms within the scope not departing from the spirit and essential features of the present invention.
