Patent ID: 7564967

Claim:
A two-dimensional slide apparatus, for a portable communication device comprising: a first member; a second member movable along a first direction in relation to the first member; a third member movable between a first position and a second position along a second direction in relation to the second member, with a first central position therebetween; and a first torque-retaining assembly disposed between the second member and the third member; wherein, when the third member moves from the first position to the first central position in relation to the second member by a first external force, the first torque-retaining assembly generates a first torque, and the first torque drives the third member from the first central position to the first position; and when the third member moves from the second position to the first central position in relation to the second member by a second external force, the first torque-retaining assembly generates a second torque, and the second torque drives the third member from the first central position to the second position.
