  • Patent number: 7140073
    Abstract: Disclosed herein is a rotation-stop mechanism for a folder of a portable wireless terminal. The rotation-stop mechanism enables the folder to be opened away from the terminal body at various angles, according to the user's need, while smoothly maintaining the opening and closing operation of the folder. The rotation-stop mechanism can stop the rotation of the folder in a state wherein the folder is opened away from the terminal body at an angle of or about 90°, according to the user's need, while allowing the folder to be smoothly opened away from or closed to the terminal body. Further, the folder can be freely opened away from the terminal body at angles of at or about 90° or at or about 150°. Furthermore, in the case of the portable wireless terminal installed with a camera lens, since the folder can be firmly fixed when it is opened away from the terminal body at an angle of or about 90°, the portable wireless terminal is advantageous for stable image capturing and video communications.

  • Patent number: 6886221
    Abstract: A folding device contains a stationary part, a movable part disposed to be rotatable in flip-up (unfolding) and flip-down (folding) directions, a force-applying section disposed between the two parts, which urges the movable part in either direction according to a state of the movable part, a reversing section for allowing the force-applying section to change a direction of urging of the movable part into the flip-up (unfolding) direction when the movable part is in a folded state, and an actuator for operating the reversing section. Pressing the actuator being in the folded state allows the reversing section to switch the direction of urging of the movable part into flip-up (unfolding) direction. In the electronic equipment of the present invention, the stationary and the movable housings are connected to the stationary and the movable parts of the folding device, respectively.

  • Patent number: 6832411
    Abstract: Abutment projections (54, 54) of a resin-made driver member (not shown) are inserted in the opposite end portions of a key groove (41) of a metal-made turnable member (4) in the circumferential direction. A key portion (B3) of a receiving cylindrical portion is inserted between the abutment projections (54, 54). The interval between the abutment projections (54, 54) in the circumferential direction is set to be slightly larger than the width of the key portion (B3). By doing so, when a transmission section is turned into an open position or a closed position, the abutment projections (54, 54) and the key portion (B3) are collided with each other, thereby generating a click sound. Moreover, since both the abutment projections (54, 54) and the key portion (B3) are formed of resin, they can be prevented from getting worn out soon.
