Patent ID: 7515707

Claim:
A portable electronic or communication device, comprising: a first panel comprising a first surface; a second panel comprising a second surface; a connector connecting the first panel and second panel; wherein the connector is configured to rotatably connect the first panel and second panel relative to each other, the second panel being rotatable about a panel rotating axis between a first rotational position and a second rotational position, the first and second surfaces facing each other and being substantially parallel to each other when the second panel is in the first rotational position; wherein the connector is configured to further slidably connect the first panel and second panel relative to each other, the second panel or a portion thereof being substantially linearly movable between a first linear position and a second linear position when the second panel is in the first rotational position; and wherein the connector is further configured to actuate rotation of the second panel from the first rotational position toward the second rotational position about the panel rotating axis when the second panel or the portion thereof is in a predetermined position between the first and second linear positions, wherein the connector comprises: a cam having a cam surface, which comprises a first spontaneous moving section; a cam follower in contact with the cam surface at a contact point, the cam follower spontaneously rotatable in a first rotational direction about a hinge axis relative to the cam surface when the contact point is located on the first spontaneous moving section; wherein one of the cam and the cam follower is substantially non-rotatable relative to the second panel, and wherein the other is rotatable about the hinge axis relative to the second panel as the cam and the cam follower rotates relative to each other; and a coupler connected to the cam or the cam follower, the coupler rotatable about the hinge axis relative to the second panel as the cam and the cam follower rotate relative to each other, the coupler being substantially linearly non-movable relative to the second panel.
