  • Patent number: 8934220
    Abstract: An electronic device is provided which firmly holds a battery pack at the time of mounting the battery pack, and can easily eject the battery pack at the time of ejection. When a battery pack 11 is housed in a battery compartment 21, and a cover 30 is slid from an attachment start position P1 to an attachment completion position P0 to cover the battery compartment 21, a regulation member 32 disposed on a rear surface 301 of the cover 30 is engaged with a battery pack locking claw 221 of a battery pack holding member 22, which locks an upper surface 11A of the battery pack 11. As a result, the movement of the battery pack holding member 22 in a direction of disengaging the battery pack locking claw 221 is regulated so that the battery pack 11 can be surely prevented from coming off from the battery compartment 21. Also, when the cover 30 moves to the attachment start position P1, the regulation member 32 is also moved and disengaged from the battery pack locking claw 221.

  • Publication number: 20120162045
    Abstract: A portable terminal includes a whip antenna, a housing that has an insertion hole for inserting the whip antenna, a printed circuit board that is disposed within the housing, the electrically conductive plate member that is abutted against the whip antenna, and the electrically conductive spring member that is arranged between the printed circuit board and the electrically conductive plate member. The whip antenna includes a slide part and a retention part. The electrically conductive plate member is positioned between the whip antenna and the electrically conductive spring member, and is pressed against the whip antenna at a second surface of the electrically conductive plate member opposite to a first surface of the electrically conductive plate member against which the electrically conductive spring member is pressed in a thickness direction of the housing.

  • Publication number: 20070053504
    Abstract: The present invention provides a connecting device which has a connecting portion capable of rotatably connecting two housing portions without protruding from the two housing portions and can stably keep the housing portions arranged so as to face each other. The connecting device includes; first and third connecting members 31 and 33 which have flexibility and foldably connect an upper housing portion 1 and a lower housing portion 2 with a predetermined gap interposed therebetween; and a second connecting member 32 which has enough restoring force and rigidity to restore a bent state to an unbent state and is curved in an arc shape in sectional view such that a concave portion of the arc is oriented in a direction where the upper and lower housing portions are folded.
