Abstract: This application provides a fingerprint recognition module having a light-emitting function and a manufacturing method therefor. The fingerprint recognition module includes a flexible printed circuit (FPC) board, a die, a light-emitting diode component, an adhesive layer, and a cover plate. The manufacturing method includes the following steps: (a) directly connecting and fixing the die and the light-emitting diode component to the FPC board, and electrically connecting the die and the light-emitting diode component to the FPC board; (b) coating the adhesive layer on an upper surface of the die; (c) covering the adhesive layer with a cover plate, to adhere the cover plate to the adhesive layer; and (d) applying low pressure injection modeling encapsulation to an encapsulation space defined between the cover plate and the FPC board, so as to form an encapsulation layer in the encapsulation space to encapsulate the die and the light-emitting diode component.

Abstract: A keyboard device includes a key switch, a base plate, a connecting element and a replaceable key. The replaceable key includes a coupling plate and a keycap. The connecting element is connected between the coupling plate and the base plate. The coupling plate includes a first sliding part. The keycap includes a second sliding part. When the second sliding part is slid relative to the first sliding part, the keycap is combined with the coupling plate or the keycap is detached from the coupling plate. Consequently, the keycap is easily assembled or disassembled. Moreover, since the connecting element is not touched during the process of disassembling the keycap, the connecting element is not damaged.

Abstract: A mouse device includes a mouse casing, a circuit board, a first sensing module, a second sensing module and a switching module. The circuit board is disposed within the mouse casing. The first sensing module and the second sensing module are disposed on the circuit board and partially exposed outside the mouse casing. The switching module is partially exposed outside the bottom part of the mouse casing. At least one of the first sensing module and the second sensing module is exposed outside the mouse casing through the switching module. Consequently, a moving resolution of the mouse device is adjustable according to the practical requirements. When both of the first sensing module and the second sensing module are enabled, the moving resolution is further increased.

Abstract: A keyboard structure includes a keycap, a supporting plate, a connecting element and a clicking element. The keycap has a top surface and a bottom surface. The connecting element is connected with the keycap and the supporting plate. The clicking element is located under the keycap. While the keycap is descended, the clicking element is pressed by the push post and subjected to curvy deformation and then the clicking element is separated from the push post. When the clicking element is elastically restored to an original position to knock on the bottom surface of the keycap, a click sound is generated.

Abstract: A keyboard device includes a circuit board and plural key structures. Each key structure includes a keycap, a hinge element and a base. The hinge element includes a first lateral wing part, a second lateral wing part and a bendable part. The first lateral wing part is connected between the keycap and the base. The second lateral wing part is connected between the keycap and the base. The bendable part is connected between the first lateral wing part and the second lateral wing part. The bendable part is thinner than the first lateral wing part and the second lateral wing part. While the keycap is moved upwardly or downwardly relative to the base, a bending angle of the hinge element and a relative position between the first base shaft and the first receiving hole are changed.

Abstract: A jig for a fingerprint identification module includes a base, a top cover and a rotating shaft. The rotating shaft is connected with the base or the top cover. The base includes plural accommodation spaces. A circuit board and a fingerprint sensor fixed on the circuit board are accommodated within the corresponding accommodation space. The top cover is fixed on the base in response to a magnetic attraction force. The top cover includes plural perforations corresponding to the plural accommodation spaces. When an output element is penetrated through a specified perforation, an isolation material is outputted from the output element and placed on a periphery of a junction between the circuit board and the fingerprint sensor.

Abstract: A detection data storage device includes a detection probe, an inspection instrument, a processor and a storage controller. The processor includes a software component. The storage controller includes a key and a prompt lamp. When a circuit is detected by the detection probe, a detection signal is generated. After the detection signal is received by the inspection instrument, a detection data is generated and transmitted to the software component of the processor. If the software component judges that the detection data matches a standard value, the software components issues a prompt signal to the prompt lamp of the storage controller. In response to the prompt signal, the prompt lamp emits a light beam. After the light beam from the prompt lamp is received by the user and the key is pressed, the detection data is stored in a storage unit.

Abstract: A keyboard device includes a base plate, a key structure and a membrane wiring board. The key structure is connected with the base plate. The membrane wiring board includes a membrane switch. The membrane wiring board is arranged between the key structure and the base plate. When the keycap of the key structure is moved upwardly or downwardly relative to the base plate, the connecting element between the keycap and the base plate interferes with the membrane wiring board or the base plate. Consequently, a click sound is generated, and a feedback feel is provided.
