Disclosed is a portable terminal with a camera lens provided on the housing of the terminal. The portable terminal includes a first guide member installed on the housing of the terminal at a position adjacent to the camera lens; a cover member having one or more guide rods, which are slidably joined with the first guide member, whereby the cover member slides on the housing so as to open or close the camera lens; one or more first stoppers formed on the first guide member; and second stoppers formed at the opposite ends of the cover member. When the cover member completely opens or closes the camera lens, the second stoppers formed on one of the opposite ends of the cover member are engaged with the first stoppers, thereby restricting the movement of the cover member.

Disclosed herein is a semi-automatic sliding device for a sliding-type portable terminal that includes a stationary member, a movable member adapted to slide under constraint while facing the stationary member by means of a closing force when out of a predetermined distance and an opening force when within the predetermined distance, at least one rolling means pressed against a lateral end of the movable member, and at least one semi-automatic driving source positioned between the stationary and movable members to provide the movable member with the opening or closing force as the movable slides. The semi-automatic sliding device is advantageous to slimness.

The present invention provides a novel sulfonamide derivative of general formula (I) useful as an inhibitor of matrix metalloproteinase (MMP), its isomers, pharmaceutically acceptable salts thereof and a process for preparing the same. Since the sulfonamide derivatives of the present invention selectively inhibit MMP activity in vitro, the MMP inhibitors comprising the sulfonamide derivatives as an effective ingredient can be practically applied for the prevention and treatment of all sorts of diseases caused by overexpression and overactivation of MMP.
