Abstract: A mobile phone having a rotational camera lens housing is provided. The mobile phone includes a first housing and a second housing. A hinge housing rotatably connects the first housing to the second housing, a rotational camera lens housing is contained in the hinge housing, and an exposurer in the hinge housing exposes a camera lens at least twice according to the rotation of the camera lens housing.

Abstract: The present invention relates to a handheld radiotelephone having a battery pack attachably and detachably equipped on a rear surface of a main body, and a locking device for allowing the battery pack to be attached or detached. The locking device operates in a perpendicular direction with a length direction of the radiotelephone, and the battery pack is attached or detached while forming an arc around an end of the radiotelephone. The locking device includes an elastic locker having a predetermined elasticity, of which one end is fixed to a predetermined position of a lower casing frame of the radiotelephone and the other end is selectively locked in a locking hole. A pusher installed on the elastic locker, for pushing the elastic locker.

Abstract: Disclosed is a battery pack locking device for a portable wireless terminal which is configured to utilize a locking method in which support protrusions formed at one end of a battery pack are engaged with support grooves formed at the terminal body of the portable wireless terminal, and the battery pack is then brought into close contact with the seat surface of the terminal body, while using a button member adapted to perform a depressing operation, thereby achieving an easy separation of the battery pack from the portable wireless terminal. In accordance with the configuration, it is possible to prevent the fingernail of the user from being damaged during the attachment or detachment procedure of the battery pack. In particular, it is unnecessary to provide an additional space for allowing a horizontal movement of the locking device. Accordingly, there is an increased flexibility in the design of the terminal appearance.

Abstract: Disclosed is a cover for protecting a jack hole, into which a terminal of a microphone or a speaker in various electronic equipments, or a portable mobile telecommunication terminal device is inserted, and which is easily opened by an insertion force of a terminal into the jack hole. The jack hole cover includes a guide holder comprising a through hole for inserting the plug terminal and being fixed to the housing of the equipment, a slide cover comprising at least two pieces and being installed on the guide holder so that the pieces of the slide cover are outwardly stretched by an insertion force of the terminal, and elastic means for supporting the pieces of the slide cover prior to inserting the terminal into the through hole of the guide holder, thereby being automatically opened by inserting the terminal into the jack hole.
