Description

Mobile Communication Terminal Equipped with Automatic Rotary Camera Set}

The present invention relates to a mobile communication terminal having an automatic rotary camera set. More particularly, the present invention relates to a mobile communication terminal that enables automatic rotation of a cylindrical camera set including an earpiece and a camera through a rotating device including a geared motor.

Conventional mobile communication terminals generally functioned as a voice call means, but as communication technology and manufacturing technology of mobile communication terminals have been rapidly developed recently, a multifunctional mobile communication terminal capable of meeting various needs of consumers has been released and commercialized. .

Recently commercialized mobile communication terminal provides various functions such as game, internet search, receiving and sending E-mail, payment, etc. in addition to voice call function. Is appearing. Accordingly, the user can take a shape of an object or take a picture of himself or herself using a camera phone, and transmit the captured image to another person.

Recently, the most widely used type of camera phone is a folding type and a slide type configured to enlarge the LCD screen. In the case of the folding type, the LCD screen is exposed to the outside in order for the user to look at the shape of the subject. There is a hassle to open the upper folder, the slide type has a disadvantage that the shooting direction of the camera is fixed to one side.

1A and 1B are front and rear views of a conventional slide type camera phone, respectively.

As shown in FIGS. 1A and 1B, a conventional slide-type camera phone includes a main body 10 having a front surface of a keypad 11 for inputting text or various symbols and a microphone 12 for inputting sound signals; Combined to overlap the front surface of the main body 10 in a structure that can be slid in a direction parallel to the front of the main body 10, LCD (Liquid Crystal Display: 21) for outputting letters, various symbols and images, output of sound It comprises an earpiece 22 for and a cover 20 having a function key 23 for executing a special function on the front.

Therefore, the user can slide the cover 20 upward to open the front surface of the main body 10 to input characters or various symbols using the keypad 11 while the keypad 11 and the microphone 12 are exposed. It is also possible to make a telephone call using the microphone 12 and the earpiece 22.

The cover 20 has a guide rail 24 at the rear side for guiding the direction of movement of the sliding motion, and the main body 10 has a guide rail 24 at a portion corresponding to the guide rail 24 when combined with the cover 20. And a coupling part (not shown) formed to enable sliding movement in a state in which it is coupled with the guide rail 24, and configured to perform sliding movement along the direction of the guide rail 24.

In addition, the rear of the main body 10 is equipped with a battery 13 for supplying power, and a mirror reflecting the image taken by the fixed camera 25 and the fixed camera 25 for capturing the image in the upper rear ( 26).

By the way, the conventional slide-type camera phone with a fixed camera 25 as described above, when the user wants to shoot a specific object or another person in front of the user, while watching the image output to the LCD 21 provided in the cover 20 You can adjust the shooting distance or angle, but when the so-called 'self-shooting', such as when the user wants to take a picture of yourself, the camera so that the rear of the main body 10 equipped with the fixed camera 25 toward the user Since you need to take a picture after positioning the phone, you cannot see the LCD 21 that outputs the image.You can see only the limited image reflected through the small mirror 26 provided next to the fixed camera 25. There was a problem in that it is difficult to adjust the distance or angle, so that the desired image can not be captured properly.

Accordingly, the present applicant can freely rotate the camera in order to solve the above problems, and is equipped with a mobile communication terminal equipped with a rotary camera to realize miniaturization by integrating the camera and the earpiece into a single structure. 2004-0070898).

2A, 2B and 2C are perspective views of a mobile communication terminal equipped with a rotary camera having a separate rotary unit, a front view of a rotary unit, and a rear view of the rotary unit, respectively.

As shown in Figures 2a to 2c, the mobile communication terminal equipped with the rotary camera is provided with a keypad 210 for the input of characters or various symbols and a microphone 220 for the front of the microphone 220 for the input of sound 200; It is formed in a structure that is slidably coupled to the main unit 200, the LCD 240 for outputting characters, various symbols and images, etc. are provided on the front, and the camera mounting hole 250 formed in a concave shape in the upper center portion ) Is formed to a size that can be mounted on the slide unit 230 and the camera mounting hole 250 is formed, and includes a rotating unit 260 having an earpiece 266 and a camera 268 for imaging. It is configured by. At this time, the earpiece 266 and the camera 268 are formed in the rotating part 260 to be exposed in the opposite direction.

On the other hand, both side surfaces of the rotating unit 260 is formed with a first rotating shaft 262 and a second rotating shaft 264 protruding in the horizontal direction, respectively, the first rotating shaft 262 on both wall surfaces of the camera mounting holes 250 And a camera coupler 252 formed in a concave groove shape so that the second rotation shafts 264 are inserted and coupled, respectively.

In addition, a slit-shaped cable outlet 265 is formed in the second rotation shaft 264 in the horizontal direction. A cable (not shown) for transmitting various signals to the earpiece 266 and the camera 268 is inserted into the rotating part 260 through the cable outlet 265 and connected to the earpiece 266 and the camera 268. .

As described above, the user can not only photograph a specific object or another person in front of the mobile communication terminal equipped with the above-mentioned rotary camera, but also easily rotate the rotating unit 260 including the camera 268 to photograph himself. have.

However, in the case of the mobile communication terminal equipped with the above rotating camera, the operation method of the rotating camera was not limited due to the limitation of the manual rotating method. It was difficult to make fine adjustments because of manual manipulation by artificial force, and it was difficult to take close-up or precise shooting. There was a problem that the image state was not clear when fingerprints were inadvertently attached to the camera lens during the manual operation of the user.

In addition, since the earpiece 266 and the camera 268 are formed on the rotating unit 260 so as to be exposed in opposite directions, the earpiece 266 must be used to make a phone call after operating the camera 268 for photographing. In order to readjust a position suitable for a telephone call, there was an inconvenience of manually operating the rotating unit 260 again.

Therefore, the present invention has been devised to solve the above problems, and the camera set including the camera and the earpiece can be automatically rotated by using a rotating device including a geared motor, thereby preventing the inconvenience of manual camera set manipulation. Auto-rotation allows for fine adjustment and fine adjustment, and automatically returns the earpiece to the correct position for phone calls, ie the earpiece faces the front of the mobile terminal when the camera mode for shooting is released. An object of the present invention is to provide a mobile communication terminal having a camera set.
