Abstract: A handheld electronic device includes a housing, and a camera lens. The housing has a hole, and a camera lens is accommodated within the housing and exposed through the hole. The device includes a slidable panel and a retractable panel. The slidable panel is slidable relative to the housing between a covering position and a uncovering position. The camera lens is covered by the slidable panel when the slidable panel is at the covering position. The camera lens is uncovered when the slidable panel is at uncovering position. The retractable panel is movable relative to the housing between a retracted position and an unretracted position. The device further includes a mechanism configured to move the retractable panel from the unretracted position to the retracted position as the slidable panel slides from the covering position to the uncovering position.

Abstract: A portable apparatus of the present invention comprises a first unit, a second unit, and a hinge device that is coupled to the first and second units such that the units can be moved to be in contact with or spaced apart from each other and allows relative sliding movement between the first and second units within a certain range. The hinge device exerts a force in a direction in which the first and second units are spaced apart from each other, through the relative sliding movement by a predetermined distance between the two units in the complete contact state of the first and second units.

Abstract: Disclosed is a coupling device for coupling first and second units with each other in a portable apparatus having the first and second units and a rotation axis. The device included a first coupling member having a rotational coupling portion connected to the first unit so that the rotational coupling portion can be rotated about the rotation axis; and a second coupling member fixedly connected to the second unit. One member of the first and second coupling members includes a track portion extending along a movement axis and the other member includes a moving portion coupled with the track portion so that the moving portion can be slidably moved along the movement axis.

Abstract: The hinge device includes a housing (30), a cam (60), a cam follower (40) to interact with the cam, and a resilient member (80). The housing contains the cam, cam follower and resilient member. The cam moves linearly, and the cam follower rotates. The cam has a peak (76), a valley (77), and a straight line section (78) in which the cam follower holds its position.

Abstract: A hinge device for coupling two units movable to folded and unfolded positions in an apparatus with the two units such as a portable radiotelephone includes a housing, a first rotating member contained in the housing to rotate about a first rotation axis, and a second rotating member rotatable about a second rotation axis. The hinge device includes a first linearly moving member that is linearly movable due to the rotation of the first rotating member, and a second linearly moving member that is linearly movable due to the rotation of the second rotating member. The hinge device includes a first resilient member for urging the first linearly moving member against the first rotating member, and a second resilient member for urging the second linearly moving member against the second rotating member.
