Abstract: A rotary switch mechanism includes a hollow cylinder, a base, a push button, a first rotatable member, a second rotatable member, a first switch, a second switch and a third switch. The base is disposed under the hollow cylinder. The first rotatable member is sheathed around the hollow cylinder. The second rotatable member is sheathed around the first rotatable member. The first switch is disposed beside the first rotatable member. The second switch is disposed beside the second rotatable member. The third switch is mounted on a first circuit board, which is disposed under the base. The first rotatable member and the first switch interact with each other to generate a first rotating signal. The second rotatable member and the second switch interact with each other to generate a second rotating signal. The third switch is triggered by the pressing rod to generate a pressing signal.

Abstract: A physical configuration of a keyboard is described. A keypad section is disposed on one surface of a main body. A first flat plate is pivotally connected with an opposite surface of the main body at one edge thereof. A second flat plate is pivotally connected with an edge side of the first flat plate at one edge thereof. Two engaging modules are disposed on the opposite surface of the main body and two sides of the first flat plate, wherein each engaging module includes a plurality of slots. A pair of sliding tracks are disposed on the opposite surface of the main body, wherein two end portions of each sliding track are a first pivot position and a second pivot position, and the first flat plate is selectively connected with the first pivot position and the second pivot position.

Abstract: An operating structure of an electric pointing device is provided. The operating structure includes a multi-directive movable part, comprising a manual operating area and at least a button. The manual operating area includes a curved surface contacted and moved by a palm of a hand, wherein the buttons are installed on the curved surface, such that the locations of the buttons are easy for fingers of the hand to touch and operate the buttons accordingly. A knob is installed on the curved surface for leaning against a part of the hand between a thumb and an index finger. In accordance, a relative position between the hand operating the curved surface and the fingers operating the buttons remains unchanged when the multi-directive movable part is moved.

Abstract: A wrist rest capable of vertically storing up keyboard includes a wrist rest, at least a movable piece and at least one wall plate. The movable piece is kept in the interior of the wrist rest body in way of being able to slide out of the wrist rest body and is pivotally connected to the wrist rest body. The wall plate is pivotally connected to the movable piece and is able to rotate a preset angle and held in position. The keyboard can rest against the wall plate after the wall plate has been rotated to the preset angle.

Abstract: A self-positioning device for a keyboard includes two protrusions adapted to be respectively formed on opposite sides of a corresponding leg, two stops each formed on a corresponding one of the protrusions, and two sectorial bosses adapted to be formed on a corresponding one of the recessed seats to correspond to the two protrusions. Each sectorial boss has a first edge and a second edge to selectively abut a corresponding one of the two stops. The selective abutting of the stops to the first and second edges enables support of the keyboard on a plan surface horizontally and inclinedly.
