Description
Technical field
The utility model is about a kind of Wireless Keyboard, particularly a kind of multifunction wireless keyboard that is provided with touch pad and card reader.
Background technology
Normally need be between known traditional computer and each peripherals via suitable transport interface, and need interconnect with signal cable, as conversion of signals action and information transmission; But, because of signal cable between each peripherals and host computer, respectively this peripherals will unavoidably can be subjected to wire influence, and range of movement, handwriting pad and the keyboard that has for example limited mouse can not surmount beyond the conductor length etc., thereby causes the inconvenience and the puzzlement of operation.
Though existing wireless keyboard and wireless mouse are just admitted by increasing consumer now, but this Wireless Keyboard remains two devices that difference is different with wireless mouse, make this Wireless Keyboard and wireless mouse take placing space respectively, and this mouse also needs a bigger sliding space, makes its unlikely being restricted when sliding.Yet, general family or office put on the desktop of computing machine, usually also be placed with other peripheral equipment (as: printer, scanner etc.) or other office appliances etc., the space that can put on the desktop is diminished, and the position that makes this mouse put is more restricted, and then causes to use and go up inconvenience in puzzlement.Simultaneously, cause another inconvenience of active computer user, be that present computing machine external interface generally all is arranged on the main frame, when the user need use Wireless Keyboard to leave computer one segment distance operating computer, then be inconvenience during if any the plug of external equipment (as USB flash disk).
Summary of the invention
Problems at prior art recited above, the utility model provides a kind of Wireless Keyboard with function of touchpad and functions of card reader, make it can break away from existing Wireless Keyboard and mouse, also make that the use of external equipment is more convenient simultaneously for many restrictions in space.
A kind of multifunction wireless keyboard of the present utility model comprises being provided with a key-press group Wireless Keyboard pedestal, it is characterized in that,
Also be provided with a central processing unit, a wireless transceiver circuit, a touch induction circuit, a card reader circuit and a power supply unit in the described Wireless Keyboard pedestal, described wireless transceiver circuit, touch induction circuit, card reader circuit and power supply unit are electrically connected with central processing unit respectively;
And by the key-press group of described Wireless Keyboard pedestal, touch pad and touch pad left and right press key are set, and in the touch pad bottom card reader is set, then can realize the connection of external equipment in this Wireless Keyboard side.
And a kind of multifunction wireless keyboard of this utility model, also comprise a keyboard switch button, a touch pad shift knob and all be arranged at the touch pad top, and corresponding on-off circuit is set in described Wireless Keyboard base interior, be electrically connected with central processing unit respectively, thereby can realize the unlatching of keyboard and touch pad or close by this keyboard switch button and touch pad shift knob.
What the key-press group that described Wireless Keyboard pedestal is provided with adopted is the notebook key-press group layout of standard, because the notebook key-press group does not have the digital keys district on desktop computer key-press group right side, so just reserved enough spaces, made that the whole size of this Wireless Keyboard is just the same big with a common desktop keyboard for being provided with of touch pad.
Also be provided with a USB interface on described Wireless Keyboard pedestal, also be provided with a charging circuit in described Wireless Keyboard base interior, this charging circuit is electrically connected with described USB interface, power supply unit respectively; Described USB interface also is electrically connected with central processing unit.Thereby can directly be connected with computer by USB interface,, also can directly realize wired operation of keyboard on the other hand by USB interface to realize the USB charging of power supply unit.And also be provided with a DC charging inlet on described Wireless Keyboard pedestal, this DC charging inlet is electrically connected with described charging circuit, cooperates adapter to use, and can realize directly using alternating current charging.
A kind of multifunction wireless keyboard of the present utility model, by touch induction circuit the movement locus of object on the touch pad is changed into digital data transmission on the one hand and give central processing unit, this central processing unit is transferred to wireless transceiver circuit after with this digital signal processing again, realize by wireless transceiver circuit again and main frame between the operation signal transmission; On the other hand also by the data read of card reader circuit realization from external memory device, and be that digital data transmission is handled to central processing unit with the data conversion that is read, and after central processing unit is handled, be transferred to wireless transceiver circuit again, again by the exchanges data between wireless transceiver circuit realization and the main frame.
Enforcement of the present utility model will greatly improve on the space restriction for the cordless key mouse, and, along with the continuous popularization of present large screen display, this multifunction wireless keyboard also provides at a distance to computation, office and audio-visual amusement more easily for the user.
