Abstract: An input device includes a universal serial bus interface, a white light-emitting diode unit, a red light-emitting diode unit, a green light-emitting diode unit, a blue light-emitting diode unit and a driving part. The driving part receives electricity through the universal serial bus and drives at least one of the white light-emitting diode unit, the red light-emitting diode unit, the green light-emitting diode unit and the blue light-emitting diode unit to emit a light beam. Consequently, the light beam with a higher luminous intensity and a specified color is outputted from the input device.

Abstract: The present invention provides a keyboard device, including a plurality of keys, thin film circuit boards, and key bottom plates. A connection component of the key is connected between a keycap of the key and a bottom plate connection portion of key bottom plate, and the bottom plate connection portion has a connection portion surface corresponding to the keycap and a raised portion formed on the connection portion surface. When the keycap moves downward relative to the thin film circuit board, a lower surface of the keycap knocks the raised portion.

Abstract: A key structure, including a keycap, a movable mechanism, a support plate, a circuit board, and an indicator light-emitting element. The support plate and the movable mechanism pivotally connected to the support plate are disposed above the circuit board. The circuit board has a groove, and the indicator light-emitting element is embedded in the groove and is aligned with the keycap. The indicator light-emitting element emits light upward. The light may be directly emitted into the movable mechanism and is subsequently emitted outward through a light hole of the keycap.
