  • Pressing-type pad structure and electronic device using the same
    Patent number: 7679905
    Abstract: A pressing-type pad structure and an electronic device using the same are provided. The pressing-type pad structure includes a pad component, an elastic element and a positioning element. The rotatable pad component is disposed on a housing of the electronic device and has at least two concave portions. The elastic element connects the housing and the pad component. The positioning element is elastically disposed on the housing. One end of the positioning element is leant against the pad component. When the electronic device is pressed or moved, an elastic force of the elastic element is applied to the pad component to drive the pad component to rotate. The positioning element is selectively inserted into one of the concave portions for fixing the pad component, so as to change the position of the electronic device.
