  • Patent number: 9230753
    Abstract: An illuminated touch keyboard includes a light source, a key structure, and a non-contact sensor board. The non-contact sensor board is used for sensing a depressing action of the key structure. The non-contact sensor board includes a light-shading plate, a light guide plate, and a reflecting plate. The light-shading plate includes a first wiring layer. The reflecting plate includes a second wiring layer. Since the light-shading plate, the light guide plate and the reflecting plate are include in the non-contact sensor board, the fabricating cost of the illuminated touch keyboard is reduced, and the overall height of the illuminated touch keyboard is decreased.

  • Patent number: 9213417
    Abstract: A keyboard device with a luminous key is provided. The keyboard device includes at least one luminous key, a top-view light-emitting element, and a light shade. The top-view light-emitting element is used for emitting a light beam. The light shade is used for shading the light beam. Moreover, the light beam is transmissible through a light-outputting part of the light shade to illuminate the luminous key. 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.

  • Patent number: 9214301
    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. The light-emitting element and the reflective layer are disposed on the flexible circuit board. 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.

  • Patent number: 9213416
    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.

  • Patent number: 9142370
    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.

  • Patent number: 9116061
    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.

  • Patent number: 9040856
    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.

  • Patent number: 9022590
    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.

  • Patent number: 8955810
    Abstract: A fastening mechanism for fastening a first object to a second object, the fastening mechanism includes a first fastening member, a driven member, a linkage member, and a first supporting member. The first fastening member is rotatably secured to the second object. The driven member is rotatably secured to the second object. The linkage member is connected between the fastening member and the driven member. The first supporting member protrudes from the second object to support the first object. When an external force is exerted on the driven member, the driven member is capable of rotating to pull the linkage member, thus the linkage member pulls the first fastening member to rotate toward the first supporting member and sandwiches the first object between the first fastening member and the first supporting member so that the first object is fastened to the second object.

  • Publication number: 20150021151
    Abstract: A luminous keyboard includes a light-emitting element, a proximity sensor, a membrane wiring board, and plural keys. The plural keys are aligned with the plural membrane switches for triggering the plural membrane switches. The light-emitting element is used for providing a light beam to the luminous keyboard. The membrane wiring board has a receiving part for accommodating a signal processing unit of the proximity sensor. In accordance with the present invention, a sensing unit and the signal processing unit of the proximity sensor are used for sensing whether an object is locate near the illuminated keyboard or not. Since the signal processing unit of the proximity sensor is accommodated within the receiving part, it is not necessary to provide an additional accommodation space for accommodating the proximity sensor. Consequently, the luminous keyboard can meet the requirements of slimness and miniaturization.
