The USB interface is embedded at two-way one end of turning one's head, and by the two-way angular adjustment that turns one's head, USB interface is connected to flat On plate host computer.
The infrared ray of RF transmitter transmitting is parallel with virtual key panel projection plane, and have 1-5 millimeters away from From.
The pointer for being provided with RF transmitter, including the touch control type switch key being arranged in the pointer, The first manual on & off switch of telescopic charge port and the second manual on & off switch of the concealed nib of control is controlled, the infrared ray is sent out Emitter is installed on pointer front, with first manual on & off switch and the second manual on & off switch not in approximately the same plane.
The first manual on & off switch and the second manual on & off switch dorsad stagger setting.
The first manual on & off switch and the second manual on & off switch are plug-type setting.
Compared with prior art, this utility model effectively can be entered to various data by way of projection virtual keyboard Row typing, is not required to arrange mechanical type physical keyboard, simplifies the structure of equipment body, while avoiding physical keyboard button mill Damage, intake, entering the economic loss that dirt is caused, realizing efficient utilization and the extended protection of panel computer, with simple and reliable for structure, Convenient to operation, can not only realize that older styled keyboards are acted on, and superior performance, greatly improve the portability of total system Property, with very high application value.This utility model is directly connected to panel computer main frame by USB interface, transmits number It is believed that number, plug and play, it is not necessary in addition configure bluetooth module and battery is easy to use.
The technique effect of design of the present utility model, concrete structure and generation is made furtherly below with reference to accompanying drawing Bright, to be fully understood from the purpose of this utility model, feature and effect.
