Abstract: An illuminated keyboard includes a key structure, a sensor board, a light source, a light guide plate, an adhesive layer, and a bottom plate. The sensor board includes a key wiring region for sensing a depressing action of the key structure and thereby generates a key signal. The light source is used for emitting a light beam to the light guide plate. The sensor board is made of a light-transmissible material. The sensor board is disposed over the light guide plate. At least one edge region of the sensor board is coated with a light-shading material or mixed with a light-shading material. Moreover, the at least one edge region of the sensor board is bent to enclose at least one edge of the light guide plate in order to prevent lateral light leakage of the illuminated keyboard.

Abstract: A luminous keyboard includes a lateral-emitting type illumination element, a light guide panel, a sensing circuit pattern, a light-transmissible substrate, a supporting plate, and plural keys. When one of the keys is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal. The lateral-emitting type illumination element is used for providing a light beam to the light guide panel. Consequently, the light beam can be diffused to the whole light guide panel. The light guide panel has plural light-guiding dots for collecting and scattering the light beam. The light-transmissible substrate is arranged between the light guide panel and the plural keys, and has plural light diffusion structures corresponding to the plural keys. The light beam scattered upwardly by each light-guiding dot is sequentially transmitted through the corresponding light diffusion structure and the supporting plate and directed to the corresponding key.

Abstract: An illuminated keyboard includes a key structure and a backlight membrane switch board. The backlight membrane switch board includes a light source, a light guide plate, a wiring plate, and a partition plate. The light guide plate includes a first circuit layer. The wiring plate includes a second circuit layer and a light source circuit layer. The electrical connection between the first circuit layer and the second circuit layer results in a key signal.

Since the first circuit layer is disposed on the light guide plate, less amount of substrates is required and the illuminated keyboard is slim. Moreover, since the second circuit layer and the light source circuit layer have a shared pin, the ease of assembling the backlight membrane switch board is enhanced.

Abstract: A luminous keyboard device includes a keypad module, a supporting plate, a flexible circuit board, a light-emitting element, a reflective layer, and a light guide plate. The supporting plate includes plural receiving parts. The flexible circuit board is contacted with the plural receiving parts to form plural bent structures.

When a light beam is emitted by the light-emitting element, the portion of the light beam that is not directed to the light guide plate is reflected back to the light guide plate by the reflective layer on the plural bent structures. Consequently, the amount of light introduced into the light guide plate increases.

The at least one luminous key includes at least one keycap and at least one elastic element. The elastic element and the light shade are integrally formed with each other. Since the total area of the bottom surfaces of the elastic element and the light shade is increased, the light shade can be securely fixed.

Abstract: An illuminated keyboard includes a key, a light guide plate, a sensing circuit layer, and a light-transmissible elastic element. The light-transmissible elastic element is disposed under the key. The light-transmissible elastic element has a light-diffusing part. The light guide plate and the sensing circuit layer are disposed under the light-transmissible elastic element. The sensing circuit layer is used for generating a non-contact key signal. After the light beam transferred within the light guide plate is transmitted upwardly through the light guide plate, the light beam is transmitted through the light-transmissible elastic element. Moreover, since the optical path of the light beam is changed by the light-diffusing part, the light beam can be projected onto the whole keycap more uniformly.

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: An exemplary embodiment of a testing device for testing a pulling force includes a shell having a test platform, a load sensor mechanism, a control system, a drive and transmission mechanism and a material clamping mechanism. Two portions of a test object are clasped by the load sensor mechanism and the clamp. When the load sensor mechanism is driven to move further away from the clamp via the drive and transmission mechanism, a pulling force perpendicular to the test platform is generated between the two portions of the test object. The load sensor mechanism detects the pulling force and feeds back the detection to the control system.

Abstract: A luminous keyboard device includes plural keys, a supporting plate, a light-emitting element, a membrane switch circuit module, and a light guide plate. The light guide plate is thicker than the light guide plate. The supporting plate has an opening corresponding to the light-emitting element. The light-emitting element is inserted into the opening. The light-emitting element is used for emitting plural light beams. A portion of the plural light beams are traveled along the path under the supporting plate and introduced into the light guide plate. Consequently, the portion of the plural light beams will be directed to the plural keys to illuminate the plural keys. Another portion of the plural light beams are traveled along the path over the supporting plate and introduced into the membrane switch circuit module. Consequently, the luminous efficiency of the slim-type luminous keyboard device is enhanced.

Abstract: A luminous keyboard device includes plural keys, a light-emitting element, and a light guide plate. By the light guide plate, a light beam emitted by the light-emitting element is guided to the plural keys. The light guide plate includes plural elongated slots and a light-absorbing part. The plural elongated slots are located near a lateral edge of the light guide plate. After the light beam transferred within the light guide plate is transmitted through the elongated slots and departed from the light guide plate, the fraction of the light beam introduced into the lateral edge of the light guide plate is reduced. The light-absorbing part is located at the lateral edge of the light guide plate for absorbing the portion of the light beam which is introduced into the lateral edge of the light guide plate. Consequently, the lateral light leakage of the light guide plate can be avoided.

When the light-emitting element emits a light beam, the light beam from the light-emitting element passes through the plural micro apertures and then passes through the operation surface.

Abstract: A luminous keyboard device includes a keypad module, a supporting plate, a flexible circuit board, a light-emitting element, a reflective layer, and a light guide plate. The supporting plate includes plural receiving parts. The flexible circuit board is contacted with the plural receiving parts to form plural bent structures.
