Abstract
The utility model provides a teaching field that area shows calculation key dish of function belongs to computer realm, the especially many key entry of appliance computer. Information display part, key entry part, a USB computer interface constitute an area shows calculation key dish of function as follows mainly. The information display part is connected with the key entry part, then is connected with a USB computer interface. A problem that area shows calculation key dish of function has mainly solved and has connected a plurality of calculation key dishes at a computer, and when every key entry person not only needed input information need carry out simple information display alone simultaneously, computer port resource was nervous. A condition that area shows calculation key dish of function mainly is applied to and uses a plurality of keyboards of computer connection. The teaching field of especially using a computer to connect a plurality of keyboards has wide application prospect.
Description
Technical field
Computer keyboard with Presentation Function belongs to a computer realm, especially a kind of teaching field of appliance computer muliple keyboards input.
Background technology
At present, mostly our computing machine used in everyday is that a host computer connects a keyboard, a display.Requirement for display is higher, and the port resource for computing machine takies seldom, also without the need to considering computer port resource problem.
But in the specific applied environment that some are concrete, not high to the requirement of computer display, only need to show some simple character or graphical informations, but the port resource of computer seems at full stretch, even not enough.Such as use host computer connect multiple keyboard impart knowledge to students time see:: application number 2015103406581, teacher carries out English word dictation to full class student, so just need to use multiple keyboard simultaneously to a host computer input character, and each classmate needs the information of oneself input and the simple response message of main frame shows and the information that inputs does not allow other student to see, at this moment main frame connects a public display device and obviously can not meet the demands, if connect the multiple display of multiple keyboard, host port resource is just at full stretch even not enough, multiple display wiring is numerous and diverse, expensive simultaneously, takes up space also larger.
Summary of the invention
For overcoming the above problems, the utility model discloses a kind of computer keyboard with Presentation Function.
A kind of computer keyboard with Presentation Function, comprise key input section (1), information display section (2), a USB computer interfaceJi Suanjijiekou (3), described a kind of computer keyboard with Presentation Function is connected with information display section (2) by key input section (1), and key input section (1) or information display section (2) are connected with a USB computer interfaceJi Suanjijiekou (3).
Further, described key input section (1) is connected as a whole with information display section (2) with USB computer interfaceJi Suanjijiekou (3) three.
Further, described information display section (2) is connected with key input section (1) by the mode of grafting, and key input section (1) or information display section (2) are connected with a USB computer interfaceJi Suanjijiekou (3).
Further, described information display section (2) is connected with key input section (1) by wired connection mode, and key input section (1) or information display section (2) are connected with a USB computer interfaceJi Suanjijiekou (3).
Further, described information display section (2) is connected with key input section (1) by radio connection, and key input section (1) or information display section (2) are connected with a USB computer interfaceJi Suanjijiekou (3).
Beneficial effect: connect in multiple input through keyboard teaching process at a main frame, student does not have host computer control to a great extent.And be only according to teacher's requirement, carry out simple information input.At this moment require lower to display, only the simple loopback message of display keyboard input information and main frame is just enough.Use the utility model, not only can solve the nervous problem of port resource when main frame connects a keyboard display respectively, input of simultaneously can economizing on the use of funds.
China is populous nation, annual enrollment crosses hundred million, various educational training school is countless especially, simple display technique, keyboard input technology, USB port mechanics of communication do not have technical difficulty for those skilled in the art, but simple ripe display technique, keyboard technique part and a USB PORT COM are integrated by the utility model, this new connection or combination just create new application, in the face of China more than one hundred million student's every day every class application scenarios, far-reaching influence will be produced to the development of China's educational undertaking.
