Abstract: A joystick includes a stick head, an actuating component, a substrate, a bearing base, a resilient recovering component and a constraining component. The actuating component has a first end and a second end opposite to each other. The first end is connected to the stick head, and an identification feature is disposed on the second end. The substrate has a detection module used to detect the identification feature and determine motion of the stick head. The bearing base is disposed on the substrate. An opening portion of the bearing base aligns with the detection module and the actuating component. The resilient recovering component is disposed between the substrate and the bearing base. The constraining component is disposed on the resilient recovering component and movably disposed inside the opening portion, and used to abut against the actuating component in a detachable manner.

Abstract: An optical identification device includes a circuit board, a top cover, an optical detection module and an optical channel. The top cover is disposed on the circuit board and has an identification region. The optical detection module is disposed on the circuit board and located inside the top cover. The optical detection module includes an optical emitter and an optical receiver. The optical emitter is adapted to emit an illumination beam toward the top cover. The optical receiver is adapted to receive the illumination beam reflected from the top cover. The optical channel is disposed between the optical emitter and the top cover, and adapted to block the illumination beam from projecting onto a lower surface of the identification region facing the optical receiver.

Abstract: A joystick includes a stick head, an actuating component, a substrate, a bearing base, a resilient recovering component, a first rotation component and a second rotation component. The actuating component has a first end and a second end opposite to each other. The first end is connected to the stick head, and an identification feature is disposed on the second end. The substrate has a detector used to detect the identification feature and determine motion of the stick head. The bearing base is disposed on the substrate. The resilient recovering component is disposed between the substrate and the bearing base. The first rotation component is movably disposed on the bearing base and rotatable in a first direction. The second rotation component is movably connected to the first rotation component and rotatable in a second direction different from the first direction, and connected to the actuating component in a rotatable manner.

Abstract: An optical identification device includes a top cover, a circuit board, an optical detection module, an optical deviation component and an anti-reflection component. The circuit board is disposed under the top cover. The optical detection module is disposed on the circuit board, and the optical detection module includes a light emitter and a light receiver. The optical deviation component is disposed on the light emitter of the optical detection module and adapted to change a transmission direction of an optical signal emitted by the light emitter, so that the optical signal is projected onto the top cover in an inclined manner. The anti-reflection component is disposed on a surface of the top cover facing the optical detection module and adapted to increase a penetration rate of the optical signal projected onto the top cover.
