A second image input unit 128 may be additionally mounted on the rear surface of the rear case 122. The second image input unit 128 may have a photographing direction substantially opposite to that of the first image input unit 15 (see FIG. 1), and may be a camera having different pixels from the first image input unit 115.
For example, the first image input unit 115 has low pixels so that the face of the user can be photographed and transmitted to the other party in case of a video call or the like, and the second image input unit 128 photographs a general object, It is preferable to have a high pixel because it is often not transmitted.
A flash 129 and a mirror 134 are additionally disposed adjacent to the second image input unit 128. The flash 129 illuminates the subject when the subject is photographed by the second image input unit 128. The mirror 134 enables the user to illuminate the user's own face or the like when the user intends to take a picture of himself / herself (self-photographing) using the second image input unit 128.
And the second sound output unit 131 may be further disposed in the rear case 122. [
The second sound output unit 131 may implement a stereo function together with the first sound output unit 114 (see FIG. 1), and may be used for talking in a speakerphone mode.

The other part of the slide module 133 may be disposed on the front case 121 side of the second body 120 and may not be exposed to the outside as in this figure.
In the above description, the second image input unit 128 and the like are disposed in the second body 120, but the present invention is not limited thereto. For example, at least one of the configurations 128 to 132 described as being arranged in the rear case 122, such as the second image input unit 128, is connected to the first body 110, mainly the rear case 112 It is also possible to mount it. In such a case, there is an advantage that the configuration (s) disposed in the rear case 112 in the closed state is protected by the second body 120. Further, the first image input unit 115 may be rotatably formed so that the second image input unit 128 can be photographed up to the second image input unit 128, even if the second image input unit 128 is not separately provided.
3 is a perspective view of a portable terminal showing a cover separated from a second body.
In this embodiment, a battery cover covering the battery 125 mounted on the rear surface of the second body 120 is illustrated as an example of the cover 140. However, the cover 140 of the present invention is not limited thereto, but can be variously modified in a form that covers the parts mounted on the terminal body.
Mounting holes 141 are provided on one surface of the cover 140. The protrusion 130 may be formed on the second body 120 and the protrusion 130 may be disposed in the mounting hole 141 of the cover 140 when the cover 140 is mounted.
The protrusion 130 may be provided with various kinds of components such as an input unit (e.g., a camera or a microphone), an operation unit, an output unit (e.g., a speaker, a display, etc.) The present embodiment illustrates that the camera 128, the flash 129, and the mirror 134 are mounted on the protrusion 130. As shown in Fig.
Although the protrusion 130 is formed integrally with the rear case 122 as a part of the rear case 122, the protrusion 130 may be coupled to the rear case 122 as a separate component It will be possible.
According to the above structure, the thickness of the second body 120 can be made slim as a whole by disposing the relatively thick parts on the protrusion 130.
An outer frame member 170 is disposed on the outer periphery of the protrusion 130. The outer member 170 is disposed on the mounting hole 141 of the cover 140 when the cover 140 is mounted and is exposed to the outside. The outer member 170 is disposed to face the side wall of the mounting hole 141 so as to restrict (or restrict) the movement of the cover and also minimize the step between the cover 140 and the protrusion 130 So that it can function as a decorative article that makes the beauty of the terminal look good.
The cover 140 is detachably coupled to the rear case 122 by sliding movement. Between the cover 140 and the rear case 122 are provided a plurality of engaging portions for engaging them.
According to the present embodiment, the engaging portion can include the engaging grooves 151 and 161 formed in the rear case 122 and the engaging hooks 152 and 162 formed on the cover 140.
The latching grooves 151 and 161 are formed to have a certain depth on the second body 120. The hooking hooks 152 and 162 extend from the cover 140 and slide on the hooking grooves 151 and 152 to be hooked on the hooking grooves 151 and 161 or to be released from the hooking grooves 151 and 161.
The cover 140 is slid in the first direction D1 when the cover 140 is attached and detached between the outer member 170 and the second body 120 so that the outer member 170 is moved in the second direction D2, And returning the mobile unit.
Here, the first direction D1 may be a direction in which the cover 140 slides when attaching / detaching the cover 140, and may be parallel to one surface (for example, the rear surface) of the second body 120, The second direction D2 may be a direction different from the first direction D1, for example, the inner direction of the second body 120. [
The mobile unit prevents the interference between the cover 140 and the outer frame member 170 by moving the outer frame member 170 when the slide for attaching and detaching the cover 140 is moved. In other words, the moving unit prevents the slide movement of the cover 140 from being restricted by the protruding outer member 170. [ Accordingly, when the cover 140 is attached or detached, the cover 140 can be slid smoothly without being influenced by the protruding outer member. Hereinafter, a detailed configuration of the mobile unit will be described.
FIG. 4 is an exploded perspective view showing the configuration of a mobile unit according to an embodiment of the present invention, in which the outer member 170 is separated from the second body 120.
The moving unit may include a moving groove 171 formed in the rear case 122 and springs 172 and 173 disposed inside the moving groove 171. [
The moving groove 171 is formed to have a depth greater than a certain level on the outer periphery of the projection, and provides a moving space for the exposed member 170 (outer member). The outer frame member 170 is moved by the action of the cover 140 to the outer frame member 170 as the cover 140 slides.
The springs 172 and 173 are disposed on the moving groove 171 to elastically support the outer member 170. The outer member 170 is returned to its original position by the elastic restoring force of the springs 172 and 173 after the cover 140 has passed.
The present embodiment illustrates that a plurality of springs, that is, the first springs 172 and the second springs 173 are arranged at a plurality of positions of the moving groove 171. [
The first springs 172 are disposed on one side of the protrusion 130. The second springs 173 are disposed on the side of the other end of the protrusion 130 and the protrusion 130. The first springs 172 and the second springs 173 may have different elastic intensities so that the movement amounts of the outer members may be different from each other.
For example, the first springs 172 can be realized in the form of a coil spring having a relatively low elastic strength, and the second springs 173 can be realized in the form of a leaf spring having a relatively high elastic strength.
According to this structure, when the cover 140 is detached, only the side of the outer member 170 that is in contact with the cover 140 is supported by the coil spring 172 and the remaining portion is supported by the leaf spring 173, 140 can be more easily moved in the second direction D2. For the reference, when the cover 140 is engaged, the protruding shape of the exposed member 170 has a relatively small influence on the slide movement of the cover 140, Structure.
5 and 6 are cross-sectional views of a mobile terminal showing an operating state of a mobile unit according to an embodiment of the present invention.
FIG. 5 shows a state in which the cover 140 is mounted on the second body 120, and FIG. 6 shows the state in which the cover is separated from the second body.
A first latching hook 152 is formed at one end of the cover 140 and a second latching hook 162 is formed at the other end of the cover 140. A first latching groove 151 and a second latching groove 161 are formed at positions corresponding to those of the second body 120. The first and second latching grooves 151 and 161 are formed with latching protrusions 153 and 163 for latching or releasing the first and second latching hooks 152 and 162, respectively.
In addition, a plurality of hooks may be formed along the inner wall of the cover 140, and latching grooves may be formed in regions corresponding to the second body 120.
5, when the cover 140 is coupled to the second body 120, the first and second hooking hooks 152 and 162 are engaged with the hooking jaws 153 and 163, respectively, The hooks 152 and 162 are engaged with the first and second hooking grooves 151 and 161, respectively.
The outer frame member 170 is disposed on the mounting hole 141 of the cover 140 so that the movement of the cover in the first direction D1 is further performed by the outer frame member 170 Lt; / RTI >
When the user pushes the cover 140 in the first direction D1, the hooking hooks 152 and 162 are deformed and the hooking hooks 152 and 162 are released from the hooking jaws 153 and 163. Thus, the latching hooks 152 and 162 are slid out from the latching grooves.
As the locking hooks 152 and 162 are released from the restraint, the cover 140 slides in the first direction D1.
On the side wall of the mounting hole 141, an inclined surface 141a 141b (or a rounded portion) is formed. These inclined surfaces 141a and 141b are formed with mounting holes on both side walls. On the outer surface of the outer member 170, there are formed inclined surfaces 170a and 170b corresponding thereto.
As the cover 140 is slid in the first direction D1, the inclined surface 141a of the cover 140 contacts the inclined surface 170a of the outer member 170a and moves relative thereto. The inclined surface 141a of the cover 140 exerts a force on the inclined surface 170a of the outer member 170 and the outer member 170 is pressed against the inclined surface 141a of the cover 140 in the first direction D1 in the second direction D2. That is, by the structure of the inclined surfaces 141a and 170a, the acting force in the first direction D1 can be converted into the acting force in the second direction D2 and transmitted.
When the cover 140 is slid for a predetermined interval, the hooking hooks 152 and 162 are completely disengaged from the hooking grooves 151 and 161 to completely separate the cover 140 from the second body 120. When the cover 140 is completely separated and the force exerted by the cover 140 on the outer frame member 170 is removed, the outer frame member 170 is returned to its original position by the resilient restoring force of the springs 172 and 173.
Although the process of separating the cover 140 from the second body 120 has been described above, when the cover 140 is coupled to the second body 120, the operation of the mobile unit is the same.
The inclined surface 141b of the cover 140 is brought into contact with the inclined surface 170b of the outer frame member 170 to apply an acting force to the outer frame member 170. As a result, (D2).
The engagement of the engagement hooks 152 and 162 of the cover 140 with the engagement jaws 153 and 163 completes the attachment of the cover 140. When the force acting on the outer frame member 170 is removed, The outer frame member 170 returns to its original position.
In the above embodiments, the configuration and operation state of the mobile unit for moving the outer frame member 170 according to the movement of the cover 140 have been described. However, the outer member 170 may be modified in various ways as long as the outer member 170 protrudes from the terminal bodies 110 and 120 and is exposed to the outside through the mounting hole 141 of the cover 140. In this specification, such a structure as a comprehensive concept will be referred to as "exposure member ". Hereinafter, another embodiment of the exposure member will be described.

The cap body 180a is configured to cover the opening 186 when mounted on the cap mounting portion 187, and may be formed of a metal material or a synthetic resin material.
The connecting member 180b extends from the cap body 180a and movably connects the cap body to the cap mounting portion. The connecting member 180b may be formed as a pair of rods moving through the through hole 188 formed in the cap mounting portion 187. A hook 180c may be formed at an end of the connecting member 180b to hook the cap mounting portion 187 when the cap body 180a is drawn out.
A moving unit is provided between the cap 180 and the second body 120. The moving unit moves the cap 180 in the second direction D2 when the cover 140 is slid in the first direction D1, Thereby preventing interference between the cover 140 and the cap 180 when the cover 140 is moved.
The moving unit may include a moving groove 181 disposed inside the opening portion and a spring 182 disposed inside the moving groove 181. [
The moving groove 181 is formed inside the opening to provide a moving space for the connecting member 180b and the spring 182 elastically supports the connecting member 180b. A supporting member 185 can be movably mounted on the moving groove 181 and the supporting member 185 supports the connecting member 180a and the spring 182, respectively. The support member 185 may have a support groove 185a corresponding to the shape of the connection member 180b.
On the side wall of the moving groove 181, a stopper 188 for restricting the movement of the supporting member may be formed.
10 shows a state in which the cover 140 is slid and separated from the mounting position of the second body 120. Fig.
As the cover slides in the first direction, the cover 140 applies a force to the cap body 180a, and the cap body 180 moves in the second direction due to the applied force from the cover. At this time, the connecting member 180b and the supporting member 185 move on the moving groove 181 in the second direction D2.
When the cover 140 is completely separated and the force exerted by the cover 140 on the cap body 180a is removed, the cap 180 is restored to its original position by the elastic restoring force of the spring 182. [ At this time, the movement of the support member 185 is restricted by the stopper 188.
The movement of the cap 180 by the mobile unit during the mounting process of the cover 140 is performed in the reverse order of the separation process, and a detailed description thereof will be omitted.
