The portable terminal 100 shown in FIG. 2A includes a bar-shaped terminal body. However, the present invention is not limited thereto. The present invention can be applied to various structures such as a slide type, a folder type, a swing type, and a swivel type in which two or more bodies are movably coupled to each other. Explain.

The body includes a case (a casing, a housing, a cover, and the like) which forms an appearance. In this embodiment, the case may be divided into a front case 101 and a rear case 102. [ A variety of electronic components are embedded in the space formed between the front case 101 and the rear case 102. At least one intermediate case may be additionally disposed between the front case 101 and the rear case 102. [

The cases may be formed by injection molding a synthetic resin or may be formed of a metal material such as stainless steel (STS), aluminum (Al), titanium (Ti) or the like.

The display unit 151, the sound output unit 152, the camera module 121, the user input units 130/131 and 132, the microphone 122, the interface 170, and the like are disposed in the front body 101 .

The display unit 151 occupies most of the main surface of the front case 101. A sound output unit 151 and a camera module 121 are disposed in an area adjacent to one end of both ends of the display unit 151 and a user input unit 131 and a microphone 122 are disposed in an area adjacent to the other end. The user input unit 132 and the interface 170 may be disposed on the side surfaces of the front case 101 and the rear case 102. [

The housing constituting the main body is constituted by the front case 101 and the rear case 102 and the first housing 100A.

The user input unit 130 is operated to receive a command for controlling the operation of the portable terminal 100 and may include a plurality of operation units 131 and 132.

The operation units 131 and 132 may be collectively referred to as a manipulating portion and may be employed in any manner as long as the user operates in a tactile manner.

FIG. 2B is a rear perspective view of the portable terminal shown in FIG. 2A. As shown in FIG. 2B, a second housing 100B coupled to the first housing 100A so as to adjust the angle of engagement with the first housing 100A is provided. The second housing 100B may be coupled to the first housing 100A by a hinge so as to be rotatable. The second housing 100B may include at least one image module 200 mounted with a lens.

The image module 200 may be, for example, a camera module 121 or a projector module 155.

The image module 200 is a concept including an illumination or a photometric sensor necessary for photographing or projecting, and may be modularized into one unit.

When photographing is required at the same position for a long time or when a video signal is converted into projection light and projected, it is necessary to change the shooting angle or projection angle of the video module.

The second housing 100B having the image module may have a smaller size than the first housing 100A. The second housing 100B includes the image module 200 and is separately provided to easily rotate the second module 100B.

In the case of photographing, in the case of a mobile terminal having a small thickness, the camera module is mounted such that the lens is exposed on the front surface or the rear surface of the housing constituting the outer shape of the main body. In order to photograph the mobile terminal while it is stationed, the housing of the mobile terminal must be held in an upright position. However, if there is no separate structure, it is not easy to erect the housing.

In addition, even when the projector module is mounted, the projector module provided on the front and rear sides of the housing may be used for projecting images, except for the case where a wall surface or a separate screen exists on the top of the mobile terminal, It is not easy to project light.

Therefore, it is preferable that the second housing is coupled to the first housing so as to adjust the coupling angle. In the embodiment shown in Figs. 2A and 2B, the second housing 100B is hinged to the first housing 100A.

Specifically, one end of each of the first housing 100A and the second housing 100B is rotatably hinged, and the second housing is opposed to a front surface of the first housing 100 on which the display unit 151 is mounted, As shown in Fig.

A seating part G on which the second housing 100B is seated can be formed on the rear surface of the first housing 100A in a state in which the second housing 100B is folded. When the seating part G is formed, a part of the second housing 100B can be seated, so that the portion of the second housing 100B protruding in the back direction of the mobile terminal in a folded state can be reduced.

In FIG. 2B, a video module 200 having a lens on the rear surface of the second housing 100B is shown. The image module 200 may be a camera module or a projector module.

If the image module 200 is a camera module, the camera module may be a camera module having different pixels from the camera module 121 (see FIG. 2A).

For example, the camera module 121 has low pixels so that it is easy to capture a user's face in case of a video call or the like and transmit the same to the other party, and a camera module as a video module mounted on the second housing 100B It is often the case that a general subject is photographed and not immediately transferred, so that it can have a high pixel.

Therefore, a flash 123 and a mirror 124 may be additionally disposed adjacent to the image module 200. The flash 123 illuminates the subject when the subject is photographed by the camera 121 '. The mirror 124 allows the user to illuminate the user's own face or the like when the user intends to shoot himself / herself (self-photographing) using the camera 121 '.

In addition, an acoustic output unit 152 'may be further disposed on the rear surface of the second housing 100B. The sound output unit 152 'may implement the stereo function together with the sound output unit 152 (see FIG. 2A), and may be used for the implementation of the speakerphone mode during a call.

The sound output unit 152 may have a different output from the sound output unit 152 shown in FIG. 2A. For example, the sound output section 152 'provided in the second housing 100B may have a larger output than the sound output section 152. [

In addition to the antenna for talking and the like, a broadcast signal receiving antenna 116 may additionally be disposed on the side surface of the first housing 100A. The antenna 116, which forms part of the broadcast receiving module 111 (see FIG. 1), can be installed to be able to be drawn out from the terminal body.

A power supply unit 190 for supplying power to the portable terminal 100 may be mounted on the first housing 100A. The power supply unit 190 may be built in the first housing 100A or may be detachable from the outside of the terminal body.

FIG. 2C illustrates a state in which the first housing 100A and the second housing 100B of the mobile terminal shown in FIGS. 2A and 2B are deployed. That is, the second housing 100B is rotated with respect to the first housing 100A. Since the second housing 100B includes the image module 200 having the lens as described above, it is possible to photograph a subject existing in the horizontal direction of the table in a state where the mobile terminal is mounted on a table or the like, It is possible to project an image on a screen or a wall surface provided vertically.

One end of the second housing 100B is hinged to one end of the first housing 100A, and the other end of the second housing 100B serves as a pedestal for a stationary surface on which the mobile terminal is mounted. Therefore, the photographing angle or the projection angle of the image module 200 provided in the second housing 100B can be adjusted.

When the image projected from the image module 200 or an image to be photographed is configured to be expressed through a part or the whole of the display unit 151, the image to be photographed or projected can be confirmed through the display unit 151, The shooting operation or the projection operation can be controlled.

That is, the image module 200 provided in the second housing 100B can rotate with respect to the first housing 100A to adjust the shooting angle or the projection angle of the image module 150.

The hinge that rotatably couples the first housing 100A and the second housing 100B is preferably capable of providing a rotational frictional force to such an extent that the adjusted angle can be maintained in a stationary state.

That is, it is necessary to provide a rotational friction force such that the deployment angle shown in Fig. 2C does not change by itself.
