Abstract: This invention relates to a game controller. The game controller particularly has two movable handles. The two movable handles can be rotated to any angle for users' holding customs and can be received for saving space. Moreover, the game controller is further integrated with functions of game control and home-use remote control, corresponding to a plurality of game control buttons and home-use remote control buttons. Thus, the game controller at least has advantages of providing two control functions.

Abstract: A clamp mechanism clamping an electronic device and connecting an object to the electronic device is provided. The mechanism includes a first clamping element, a second clamping element slidably joined to the first clamping element in a joint position to adjust the second clamping element apart from the first clamping element to a clamp distance, a latching element inserted into the joint position to maintain the first clamping element apart from the second clamping element at the clamp distance, and a connecting element joined to the second clamping element and connected to the object.

Abstract: A light source device including a light-guiding pillar, an opaque layer, and a light source is provided. The light-guiding pillar has a light incident surface and a light emitting surface, and the light incident surface is adjacent to the light emitting surface. In addition, the opaque layer is disposed on the surfaces of the light-guiding pillar outside the light incident surface and the light emitting surface. The light source is disposed near the light incident surface. The light emitted from the light source propagates into the light-guiding pillar through the light incident surface, and then emits from the light emitting surface.
