The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal having a structure for facilitating photographing when a subject of an optical device provided is a user.

Recently, various electronic products such as various mobile phones, digital cameras, and digital camcorders have been released, and the convergence trend of the products is prominent among these electronic products. In the case of a mobile phone, a mobile phone product having various functions has been released, such as a role of a PDA, in addition to a function as a simple means of communication.

In particular, in recent years, the combination of optical devices such as digital cameras and mobile phones has been activated, and the development of digital cameras in mobile phones has been constantly progressing, such as the resolution of digital cameras as a single product. As the resolution of the optical device added to the mobile phone increases, the user's desire to implement a still image or a moving image having better image quality is increasing.

As an example of the prior art, Korean Patent Laid-Open Publication No. 2004-70897 discloses a slide-type mobile phone having a camera as an optical device. One example of such a prior art is shown in FIG. 1. In FIG. 1, the slide-type mobile phone 1 includes an upper slide 10 and a lower slide 20. An optical device unit 30 is provided on a rear surface of the upper slide 10, and a removable slide is attached to the lower slide 20. The battery 21 may be detached through the button 22. The upper slide 10 and the lower slide 20 slide through a guide element 11 provided in each. The optical device unit 30 includes a camera 32, a lamp 33, and a mirror 33.

When photographing the user himself with the mobile phone according to the prior art, the user checks the shooting distance and angle through the mirror. However, setting a distance and a photographing angle with respect to a subject through a small mirror, particularly a convex mirror, has difficulty in capturing an image desired by a user. That is, a significant difference occurs between the image displayed in the mirror and the image that the user wants to photograph, causing a problem that the user cannot obtain the desired image. In addition, the shooting angle of the subject is limited due to the fixed angle of the camera, and thus there is a problem that the user does not satisfy the desire for selecting various shooting angles.
