Abstract: An illuminated keyboard includes a key structure, a key wiring board, and a light-emitting element. The light-emitting element is located at a lateral side of the key wiring board. The key structure is disposed over the key wiring board. When the key structure is depressed, the key wiring board is triggered to generate a corresponding key signal. Moreover, a light-guiding structure is formed on the key wiring board. The light beam transferred within the key wiring board is guided by the light-guiding structure to be scattered to the key structure. After the light beam to be scattered to the key structure is converged by a light-converging microstructure on the key wiring board, the light beam is converged and centralized to be directed to keycap of the key structure.

Abstract: An illuminated keyboard includes a keycap, a keycap guiding frame, a light guide plate and a sensing circuit layer, which are sequentially arranged from top to bottom. The keycap guiding frame is used for fixing the keycap and guiding movement of the keycap. The light guide plate is used for fixing the keycap guiding frame and transferring the light beam from a light-emitting element. As the keycap is depressed by the user, the approaching keycap is sensed by the sensing circuit layer, and thus the sensing circuit layer generates a corresponding non-contact key signal.

Abstract: A computing device and an input device are provided. Each of the computing device and the input device includes a control unit, a light source, a projection plate and a casing. The control unit, the light source and the projection plate are accommodated within the casing. The light source emits light beams. The projection plate includes a pattern. After the light beams pass through the projection plate, the light beams are projected outside the casing and an image corresponding to the pattern of the projection plate is formed on a projection surface that is located outside the casing. Since the projection plate is cheap and small, the fabricating cost of the computing device or the input device is reduced and the purpose of developing the computing device or the input device toward light weightiness, slimness and small size is achievable.

Abstract: The present invention provides a multi-stage input device. The multi-stage input device includes a keycap, a multi-stage cushion component, and a circuit board assembly. The multi-stage cushion component is located between the keycap and the circuit board assembly to support the keycap. When the keycap is depressed to a light pressing level position, the keycap triggers a multi-stage switch of the circuit board assembly, so that the multi-stage switch generates a light-pressing signal to perform a first function. When the keycap is depressed to a heavy pressing level position, the keycap triggers the multi-stage switch of the circuit board assembly, so that the multi-stage switch generates a heavy-pressing signal to perform a second function.

Abstract: A key structure includes a pedestal, an upper cover, a light-emitting element, a triggering element, an array-type sensing element and a control unit. The light-emitting element emits a light beam. The triggering element is arranged between the pedestal and the upper cover. The triggering element includes a reflecting part. The light-emitting element and the array-type sensing element are located under the reflecting part. When the key structure is depressed, the key structure is moved relative to the pedestal. The light beam from the light-emitting element is reflected by the reflecting part and then received by the array-type sensing element. As the triggering element is moved, the array-type sensing element generates plural images. The control unit generates a corresponding pressure sensing signal according to the plural images.

Abstract: A keyboard includes a base plate, a pressure sensing layer, a first key structure and a second key structure. The pressure sensing layer includes plural pressure sensing regions. Each of the first key structure and the second key structure corresponds to a pressure sensing region. Moreover, the first key structure and the second key structure are located over the corresponding pressure sensing regions. In response to different magnitudes of the depressing force, the corresponding pressure sensing regions are pushed by the first key structure and the second key structure. Consequently, the corresponding pressure sensing regions generate different pressure sensing signals. The pressure sensing layer can replace plural pressure sensing element. Consequently, the assembling process is simplified, and the assembling cost is reduced.

Abstract: An optical switch keyboard includes a circuit board and plural keys. The circuit board includes plural light emitters and plural light receivers. Each key is aligned with the corresponding light emitter and the corresponding light receiver. Moreover, each key includes a triggering element, a first reflective element and a second reflective element. When the triggering element is triggered by the user, a sensing light emitted by the light emitter is reflected to the second reflective element by the first reflective element. The sensing light is further reflected to the light receiver by the second reflective element. Consequently, the circuit board generates a key switch signal.

Abstract: A key structure includes a movable element, an elastic element, a light-emitting element and a pressure sensing element. The pressure sensing element is arranged between the elastic element and the light-emitting element. The elastic element is disposed on the movable element. The light-emitting element emits a light beam. The light beam is transmitted through the pressure sensing element and projected to the movable element to illuminate the key structure. While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals.
