As shown in Fig. 1, Fig. 2a and Fig. 2b, the camera device 100 for easy bi-directional shooting according to the present invention is installed in a predetermined case, in which the case is a front case 200 and the rear for convenience. It is shown in the form having a case 300. The front case 200 and the rear case 300 are combined with each other to form a case in which a camera is built, such as a camera case or a portable terminal case.

The camera device 100 includes a reflector 110 and a digital camera module 150 (hereinafter abbreviated as a camera module). The reflector 110 receives an image of a subject located outside the front case 200 and the rear case 300 and reflects the image to the camera module 150.

The reflector 110 has a hollow frame 120 that is bidirectionally opened. The hollow frame 120 passes through the front and rear cases 200 and 300 back and forth and is rotatably coupled. Therefore, both ends of the frame 120 communicate with the outside of the front and rear cases 200 and 300.

Inside the frame 120, the double-sided mirror member 130 is installed at an angle of 45 degrees with respect to the axis X of the frame 120. The double-sided mirror member 130, as it is, has a mirror surface on both sides. That is, it has a first mirror surface 131 and a second mirror surface 132. Therefore, the first mirror surface 131 and the second mirror surface 132 can reflect the subject in the opposite direction.

In the embodiment shown in the drawing, the marking portion 80 includes a turning knob 124, that is, an arrow R indicating the rotational direction of the frame 120, and a letter W indicating the photographing direction. do. The letter W may use 'OUT' and 'IN', or other characters. Here, 'OUT' means photographing a direction opposite to the liquid crystal screen 31, and 'IN' means photographing a direction facing the liquid crystal screen 31.

Hereinafter, an operation process of performing photographing using a camera device in a portable terminal according to the present invention will be described.

5A to 5C, the upper main body 30 is opened with respect to the lower main body 20. Accordingly, the user may photograph the object in the opposite direction of the liquid crystal screen 31 or face the liquid crystal screen 31 in the same direction as the liquid crystal screen 31 as it faces (directly faces) the liquid crystal screen 31 of the upper body 30. It is possible to shoot their own.

Specifically, the initial state is shown in FIG. 5A. In this initial state, the turning knob 124 faces 'OUT', and the double-sided mirror member 130 inside the frame 120 of the reflector 110 has its first mirror surface 131 and the first through hole. 121 faces the camera module 150. Therefore, the image of the object in the opposite direction of the liquid crystal screen 31 is incident on the camera module 150 through the first mirror surface 131 and displayed on the liquid crystal screen 31.

FIG. 5B shows a view in which the reflector 110 is rotated in the opposite direction so as to change the photographing direction to the user's own direction, thereby reaching an intermediate point of rotation. In order to change the photographing direction, when the user rotates the turning knob 124 in the direction of the arrow R, the reflector 110 is integrally rotated. At this time, the guide shaft 50 moves in a direction in which the distance between the pivot point and the guide block 70 is narrowed as the reflector 110 rotates. Thus, the elastic member 60 is compressed as much as possible.

FIG. 5C illustrates a state in which the reflector 110 is rotated to the end in the opposite direction to change the photographing direction to the user's own direction. When the user turns a little more in the state of FIG. 5B, the restoring force of the elastic member 60 acts as a force for rotating the frame 120 of the reflector 110. Thus, the frame 120 of the reflector 110 is automatically rotated to the end (up to a 180 degree angle). In this state, the turning knob 124 faces 'IN'. In the state where the frame 120 of the reflector 110 is rotated to the end, the frame 120 of the reflector 110 is continuously pushed by the elastic pressing force of the elastic member 60, so that the reflector 110 is 180 degrees. The angle rotated state is maintained. Therefore, at this time, the user's own image is incident on the second mirror surface 132 of the double-sided mirror member 130, the second mirror surface 132 is reflected toward the camera module 150, the user's own shooting is It becomes possible. In addition, the user may perform photographing while checking his / her own image displayed on the LCD screen 31 facing each other.

As described above, the camera device and the portable terminal according to the present invention can change the photographing direction by rotating the reflector 110 without moving the camera module 150 both when photographing an object and when photographing a person. Therefore, since there is no fear that the electric and signal lines that are connected to the camera module 150 are twisted or twisted, there is no problem of disconnection of the electric and signal lines that has been generated by rotating the camera module 150 in accordance with the shooting direction. It does not occur. In addition, bi-directional shooting is possible by a simple operation of turning the turning knob 124, and the liquid crystal screen 31 can be checked at all times, so that shooting using a portable terminal is convenient.

Although specific embodiments of the present invention shown in the accompanying drawings have been described in detail above, this is only one example, and the protection scope of the present invention is not limited thereto. In addition, the embodiments of the present invention as described above can be variously modified and equivalent other embodiments by those of ordinary skill in the art within the technical spirit of the present invention, such modifications and equivalent other embodiments are It goes without saying that it belongs to the appended claims of the invention.

As described above, the camera device according to the present invention has a configuration in which the photographing direction can be switched by rotating the reflector without the movement of the camera module.

In the related art, since the camera module had to be rotated according to the photographing direction, a disconnection problem due to fatigue of electric and signal lines connected to the camera module occurred.

However, according to the present invention, there is no need to move the camera module both when photographing an object and when photographing a person, so that there is no fear of twisting or twisting the electric and signal lines connected to the camera module.

In addition, according to the present invention, bi-directional shooting is possible by a simple operation of turning a turning knob, that is, a reflector, and the liquid crystal screen can be always checked, which makes shooting with a portable terminal convenient.
