The utility model arranges the USB interface and the card reading slot on the keyboard, in order that the external storage equipment can realize the data communication of the host computer through being spliced on the keyboard, not only the splicing is convenient, but also the connection quantity and the occupied space of peripheral devices of the host computer are reduced, the problem of the shortage of host computer interface resources is effectively solved, and the function of the computer keyboard is expanded.
Description
Technical field
The utility model relates to a kind of keyboard, specifically, relates to a kind of keyboard structure that can communicate by letter with External memory equipment realization grafting.
Background technology
March toward today of information age, computing machine become all kinds of enterprises even individual process information, understand society, receiving and dispatching mail, carry out the indispensable important tool of work such as commercial intercourse.As everyone knows, existing computing machine generally all comprises basic configuration such as main frame, display screen, keyboard and mouse.Keyboard is connected main frame as input equipment by data line with mouse, transmits user's operational order to main frame.
In recent years, along with reaching its maturity of USB USB data transfer pattern, USB interface was extensively popularized, and increasing peripheral hardware all selects to adopt USB interface to carry out data transmission, such as Digital Video, digital camera, MP3, portable hard drive etc.Computing machine is in order to be connected communication with said external USB memory device, need on its main frame, USB interface be set, the external USB memory device only needs the USB interface on its USB interface and the main frame is plugged, and can realize the exchanges data between computing machine and the peripheral hardware, realizes information sharing.And for present many keyboards and mouse, also adopted the USB transmission mode to connect USB interface on the main frame, the push button signalling of key circuit output is converted to usb data passes to main frame, realize the real-time response of main frame to user instruction, people are referred to as USB keyboard or USB mouse with this keyboard and mouse usually.We know, USB interface quantity on the main frame is limited, disposed the computing machine of USB keyboard and USB mouse, it is nervous more that USB interface resource on its main frame can become undoubtedly, be unfavorable for the communication that is connected between computing machine and the External memory equipment, bring inconvenience for user's daily use.
The utility model content
The utility model is for the problem of the USB interface resource anxiety that solves main frame in the prior art, a kind of novel computer keyboard is provided, make the prior USB keyboard have the function of pegging graft and communicating by letter, alleviate main frame interface resource purpose in short supply to reach with External memory equipment.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of keyboard of the External memory equipment of pegging graft, comprise the keyboard body, the housing of described keyboard is provided with at least one USB interface and at least one card reading slot, be provided with USB controller and card reader in the inside of described USB keyboard case, described card reader is connected between described card reading slot and the USB controller, finishes the conversion of data layout; Described USB controller also connects key circuit and the described USB interface in the keyboard respectively, and connects the USB interface of main frame, transmission usb data and control signal by cable.
Further, described USB interface comprises conventional USB interface and/or miniUSB interface.
For pegging graft conveniently, described USB interface is arranged on the front panel of keyboard; Preferably be arranged on the upper right corner of keyboard front panel.
Certainly, described USB interface also can be arranged on a side or the both sides of keyboard case.
Further again, described card reading slot is arranged on a side or the both sides of keyboard case.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is by being provided with USB interface and card reading slot on keyboard, make the External memory equipment can be by being plugged on the data communication that realizes on the keyboard with main frame, it is convenient not only to peg graft, and reduced the main frame peripheral device number of connection and take up room, efficiently solve the problem of host interface resource scarcity.Simultaneously,, can be implemented in a plurality of USB interface and card reading slot are set on the keyboard, so just can finish a plurality of USB outer by a USB interface of main frame if the use of memory card device by USB controller and keyboard are integrated.
Description of drawings
Fig. 1 is the structural representation of the keyboard of the pegged graft External memory equipment that proposes of the utility model;
Fig. 2 is the internal circuit theory diagram of keyboard shown in Figure 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Referring to shown in Figure 1, keyboard of the present utility model is the USB keyboard, comprise keyboard body 1, for convenience of grafting USB External memory equipment or storage card on keyboard, on the external shell of described keyboard, offer at least one USB interface 2 and at least one card reading slot 3, described USB interface 2 can comprise conventional USB interface 2-1 and miniUSB interface 2-2, perhaps both one of.Present embodiment is considered from making things convenient for use angle, and a conventional USB interface 2-1, a miniUSB interface 2-2 and a card reading slot 3 preferably are set on keyboard case, with the use of directly pegging graft of convenient dissimilar External memory equipment.Certainly, the utility model is not limited in above-mentioned giving an example, and the developer can be according to a plurality of USB interface 2 of the concrete needs of user equipment on keyboard and card reading slot 3, to satisfy the grafting user demand of the many peripheral hardwares of user.
Described USB interface 2 can be arranged on the front panel of keyboard, perhaps a side or the both sides of keyboard case; Card reading slot 3 can be arranged on a side or the both sides of keyboard case.Consider the plug custom of staff, preferably USB interface 2 is arranged on the upper right corner of keyboard front panel; Card reading slot 3 is arranged on the right side of keyboard case, referring to shown in Figure 1, to make things convenient for the plug of user's right hand.Certainly, described USB interface 2 and card reading slot 3 also can be arranged on other positions of keyboard case according to user's actual needs, and the utility model does not specifically limit this.
