The instant disclosure relates to a wireless input device and a key-shaped receiver thereof; in particular, to a wireless input device having a key-shaped receiver for wireless communication with the computer.
The wireless input device utilized commonly in recent days such as the wireless keyboard, requires a receiver connected to the computer for wireless communication. The majority of the conventional receivers are arranged individually packaged, this not only increases the chances for the receivers to get lost, but also results in pairing confusions during production.
Conventionally, the receivers are accommodated in the base portion of the wireless input device. Such method requires an accommodating slot to be formed on the base of the wireless input device. This type of arrangement simply reduces the aesthetics of the base of the wireless input device, and the users also have to flip the wireless input device over in order to extract the receiver, bringing about utilization inconvenience.
To address the above issues, the inventor strives via industrial experience and academic research to present the instant disclosure, which can effectively improve the limitations described above.
The object of the instant disclosure is to provide a wireless input device and a key-shaped receiver thereof, where the key-shaped receiver is fixed to the top portion of the wireless input device, along with other function keys.
In order to achieve the aforementioned object, the instant disclosure provides a wireless input device, comprising a top housing and a receiver. The top housing has an accommodating slot concavely formed thereon. The receiver has a key cap, a receiving circuit module and an electrical connector arranged on the base portion of the receiving circuit module. The receiving circuit module is arranged adjacent to a bottom side of the key cap. The electrical connector is detachably received by the accommodating slot.
In order to achieve the aforementioned object, the instant disclosure provides a key-shaped receiver which includes a key cap, a receiving circuit module arranged in the key cap, and an electrical connector electrically connected to the receiving circuit module.
The instant disclosure provides the following advantages. No additional packaging is required by the receiver, and the receiver need not be arranged on the base portion of the wireless input device. In other words, no additional retaining slot or retaining mechanism is required to be provided on the base portion of the wireless input device to secure the receiver. In addition, the user can extract the receiver directly from the top portion of the wireless input device, without flipping the wireless input device over to obtain the receiver.
In order to further appreciate the characteristics and technical contents of the instant disclosure, references are hereunder made to the detailed descriptions and appended drawings in connection with the instant disclosure. However, the appended drawings are merely shown for exemplary purposes, rather than being used to restrict the scope of the instant disclosure.
The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the instant disclosure. Other objects and advantages related to the instant disclosure will be illustrated in the subsequent descriptions and appended drawings.
Referring to
The wireless input device 100 includes a top housing 10 and a receiver 20. The top portion of the top housing 10 has a plurality of keys arranged thereon, and an accommodating slot 12 is concavely formed on the top portion of the top housing 10. The receiver 20 has a key cap 22, a receiving circuit module 23 arranged adjacent to a bottom side of the key cap 22, and an electrical connector 24 electrically connected to the receiving circuit module 23. The electrical connector 24 is detachably received by the accommodating slot 12. The receiving module 23 mainly includes a circuit board and electrical components arranged thereon, such as the microprocessor control unit (MCU), the Radio Frequency Integrated Circuit (RFIC), and the memory device utilized to receive and send signals wirelessly.
The receiving circuit module 23 can be fixedly arranged in the key cap 22. To provide further illustrations, the receiving circuit module 23 is enclosed in the key cap 22, and is electrically connected to the electrical conductor 24. The key cap 22 can be a common character key, a hot key, an additionally arranged key, or a replacement for less often used hot key. Furthermore, the hot keys, also known as quick keys, refer to specific keys for accomplishing particular commands. Some examples are Fn keys from F1 to F12, the e-mail key, the browse key, the play key and so on. The common character keys refer to the keys excluding the hot keys, which include the character keys, the numeric keys, the note keys and so on, and it is not limited to by this. The receiver 20 of the instant disclosure is arranged on the top portion of the keyboard and disguised in a key-shaped structure, such that the outer appearance of the receiver 20 does not distinct from other keys of the keyboard in any aspect (shown in
The instant disclosure provides the following advantages. No additional packaging is required by the receiver 20, and the receiver 20 need not be arranged on the base portion of the wireless input device 100. In other words, no additional retaining slot or retaining mechanism is required to be provided on the base portion of the wireless input device 100 to retain the receiver 20. In addition, the user can extract the receiver 20 instantly without flipping the wireless input device 100 over. During the process of production, the receiver 20 can be inserted directly into the corresponding accommodating slot 12 to avoid the risk of being lost, as well as reducing the packaging procedures.
The wireless input device 100 of the instant embodiment can further include a micro switch 14 for power disconnection, which is arranged adjacent to the accommodating slot 12. The receiver 20 establishes contact with the micro switch for power disconnection when inserted into the accommodating slot 12, thereby enabling the power supply of the wireless input device 100 to be cut off for energy saving purposes. In other words, whenever the receiver 20 is stored in the keyboard implies that the keyboard is not under operation. Therefore, a micro switch 14, which is activated by the receiver 20, can be arranged within to cut off the power supply to the keyboard automatically to reduce energy consumption.
