Abstract: An haptic actuator includes: a base member; a hollow cylindrical coil arranged in the upper portion of the base member; a core formed in the base member and arranged so as to be inserted into the center of the coil; a cover member covering the upper portion of the base member; a vibration plate mounted on the cover member, arranged in the upper portion of the core, and moving in the vertical direction; and a vibration unit coupled to the vibration plate and spaced apart from the upper portion of the core. The vibration plate has a mounting portion fixedly mounted on the central area of the cover member and a coupling portion formed so as to extend from the mounting portion and be bent in the downward direction. The vibration unit has a permanent magnet coupled to the coupling portion and spaced apart from the core.

Abstract: Disclosed herein is a camera protection apparatus for preventing foreign matters from entering a camera. The protection apparatus includes a shield frame installed frontward of the camera lens and having a sliding space for opening the front side of the lens. A blade is slidably installed in the sliding space to open and close front side of the lens. The blade is formed with a protrusion. A rotary lever is rotatably coupled with the shield frame. The rotary lever has a central opening formed at the rotational center thereof for opening the front side of the lens. The rotary lever has a cam groove formed so as to be engaged with the protrusion such that rotation of the rotary lever causes the protrusion to move to open and close the blade. The camera protection apparatus exposes the camera when it is to be used, and otherwise to close the camera opening. Thus, foreign matters can be prevented from entering the camera.

Abstract: Disclosed is a shutter apparatus for small cameras. According to the first embodiment of the invention, a shutter housing is mounted in an exposure aperture formed in a main body. The shutter housing has a through-hole communicated with the exposure aperture. A shutter panel is pivotably mounted inside the shutter housing so as to open and close the through-hole. A pivot lever is rotatably installed inside the shutter housing and engaged with the shutter panel such that the shutter panel is pivoted to open and close the through-hole. Thus, the opening is opened only when the camera is used to take a picture, and otherwise the opening is closed, thereby efficiently preventing introduction of foreign matters into the inside of the camera.

Abstract: Disclosed herein is an apparatus for opening and closing a portable terminal. The apparatus includes a second cam, which has an upper rib to be latched with the upper portion of the housing and a lower rib to be latched with the bottom of the housing, thereby providing structural stability. In addition, frictional wear and noise can be suppressed while the second cam moves, thereby improving the service life and reliability of the device.

Abstract: Disclosed herein is a slide-up opening and closing apparatus for a communications terminal. The apparatus includes a slider unit, a slider assembly and an angular positioning member in order to open a slider body with respect to a main body. With the apparatus, the slider body can be opened with a desired inclination against the main body and after a certain degree of opening, automatically complete its opening operation without any further force or action, thereby providing a convenient use. In addition, the slider body can be opened with freedom without interference by the main body. Further, when the slider body is opened, most of the top face of the main body can be exposed, thereby providing a convenience of use.

Abstract: Disclosed is a display tilting mechanism for a communication terminal, in which a display is rotatably connected to a supporter hingedly pivoting on a main body of the communication terminal. The mechanism includes a fixing unit fixedly installed in the supporter. A rotating unit is connected with the display and rotatably installed relative to the fixing unit. A supporting unit is connected with the fixing unit in such a way that the rotating unit is not released when it rotates on the fixing unit. A retaining unit is provided for holding the rotating unit in place at the initial state and rotated state thereof when rotated on the fixing unit. Thus, when watching a movie or the like, the image can be display in a normal orientation.

Abstract: Disclosed is a hinge mechanism of portable phone having an advanced configuration, which can perform the opening operation and the rotating operation of a phone cover. The hinge mechanism comprises a housing to connect a phone body and a phone cover, which has a rotary chamber and a hinge chamber, a hinge part to open and to close he phone cover, which is disposed in the hinge chamber, and a rotary part to rotate the phone cover, which is disposed in the rotary chamber. A user can play a game or watch a motion picture using the portable phone while looking at the liquid crystal display of the phone cover, because the phone cover can be rotated.

Abstract: Disclosed is a hinge device of a portable wireless terminal. The portable wireless terminal includes a first housing, a second housing rotatably coupled to the first housing in such a manner that the second housing moves away from the first housing or approaches the first housing according to a rotational movement thereof, a first hinge axis extending parallel to an upper surface of the first housing, and a second hinge axis extending perpendicular to the upper surface of the first housing and providing a rotational center for the first hinge axis. The first and second hinge axes act as rotational axes of the second housing when the second housing rotates with respect to the first housing.
