Description
Technical field
The utility model belongs to portable computer technical field, is specifically related to a kind of portable computer by travelling keyboard positioning cursor.
Background technology
The notebook computer of current use, comprise main frame, display screen and mouse, hinge-coupled is passed through between display screen and main frame, and live wire electrical connection, mouse is by connecting electric wire or being connected with main frame by wireless launcher, main frame comprises keyboard and touch pad, keyboard also comprises membrane keyboard, left button, middle key and right button, left button wherein and the functional equivalent of right button are in the left button of mouse and right button, the function that the functional equivalent of middle key is pressed in the roller of mouse and decontroled, touch with paddling with finger or stir the function that touch pad and membrane keyboard be equivalent to reorientate when mouse moves about cursor position on display screen.
Current notebook carries more convenient, but uses and also have inconvenient part.
The first is because display screen and main frame are linked togather, can not separate, if the position of placing is suitable for operation keyboard, need to bow one's head when then observing display screen, cause neck more tired, the time has been grown and has caused suffering from cervical spondylosis, if the location comparison placed is high, be suitable for observing display screen, then need again during operation keyboard to lift arm always, cause arm tired.
It two is that the area of touch pad is too little, can not do larger again because touch pad and membrane keyboard use inconvenient, and finger paddling touch pad is easy to just draw on edge, needs a mobile position paddling again, not too convenient; Membrane keyboard is not too accurate when positioning cursor, and the distance of movement is sometimes too many, movement sometimes very little, need to descend speed carefully to operate slowly, cause work efficiency lower; Further, when typing word, finger is always encountered on membrane keyboard because of carelessness, has reorientated unintentionally cursor, if not have to note seeing display screen, can in the position typing of mistake word, need editor and correct, causing work efficiency to reduce, use inconvenience.Although with the function of mouse on keyboard, use inconvenient, people still will carry mouse when going on business or travel while carrying notebook computer, and mouse takies the space of computer package, increase its weight, carry inconvenience.
In a word, a kind of display screen and main frame split type, cursor locates design proposal more easily and urgently releases.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provide a kind of display screen and main frame split type, cursor location is more easily by the portable computer of travelling keyboard positioning cursor.
The utility model is achieved through the following technical solutions:
By a portable computer for travelling keyboard positioning cursor, comprise main frame and keyboard;
Keyboard comprises keyboard body, keyboard body lower surface has light hole, have the electric elements of transmitting and receiving light beam inside light hole, and the electric elements in mouse there is identical function, by irradiating the position of desktop for computer desk and the upper cursor of reception reflected light locating and displaying screen; Keyboard upper surface has common key-press, also has left button, middle key and right button, left button wherein and the functional equivalent of right button in the left button of mouse and right button, the function that the functional equivalent of middle key produces when the roller of mouse is pressed and/or decontroled;
Main frame comprises display screen, and also comprise other component that the traditional notebook host computers such as mainboard, internal memory, hard disk, video card are necessary, the component of computer is arranged in inside main frame as far as possible and is not arranged in inside keyboard, to alleviate the weight of keyboard;
