Description
Technical field
The utility model relates to a kind of shadow blank all-in-one.
Background technology
In recent years, along with country is to the increasing of education sector dynamics of investment, " Linking All Classes;;, the propelling of the engineering such as " middle and primary schools' long-distance education "; universities and colleges of each universities, middle and primary schools are all in the transformation advancing multi-media classroom, and electronic whiteboard and education projector are as the important component part of multi-media classroom, and after market will present the gesture of rapidly growth.
Interactive white board is the human-computer interaction device that a kind of education or meeting are assisted, it can coordinate the instrument such as projector, computer, realize dust-free writing, arbitrarily write, the function such as remote communication, interactive white board is in the market based on induction electronic whiteboard and infrared diode formula electronic whiteboard, its installation is loaded down with trivial details, price is high, and blank is fragile.And independent infrared camera electronic whiteboard is owing to will ensure that camera covers whole view field, need to carry out camera angular setting for the projected image size of projector, install, debugging is very loaded down with trivial details, cannot arbitrarily movement, use trouble inconvenience very.
Utility model content
In view of the above-mentioned problems in the prior art, fundamental purpose of the present utility model is to address the deficiencies of the prior art, the utility model provides a kind of shadow blank all-in-one, this all-in-one makes projector and electronic whiteboard module integration be integrated, the common projection screen of arbitrary dimension can be become interactive white board, whole device is simple and reliable, with low cost, practical function, install, debug conveniently, can arbitrarily adjust interactive white board size according to installation environment, and without the need to carrying out angular setting to the camera in projector again, dirigibility is high.
The utility model provides a kind of shadow blank all-in-one, comprise projector, the side of described projector is provided with projection head, the electronic whiteboard module comprising camera is provided with in projector and projection lens homonymy, there is between described camera and the bottom surface of projector the elevation angle of 20 ° ~ 50 °, the outside of described electronic whiteboard module is provided with workbin, described workbin carries out dismantled and assembled being fixedly connected with described projector, described workbin is connected by multiple draw-in groove with projector, the screw pole of multiple reference column and fixing described electronic whiteboard module is provided with in described workbin, the top of described projector is provided with heat abstractor.
Optionally, there is between described camera and the bottom surface of projector the elevation angle of 30 ° or 40 °.
Optionally, described camera is Radio infrared camera.
The utility model has the following advantages and beneficial effect: shadow blank all-in-one of the present utility model makes projector and electronic whiteboard module integration be integrated, the common projection screen of arbitrary dimension can be become interactive white board, when user uses, only need to connect projector, interactive operation can be carried out, whole device is simple and reliable, with low cost, practical function, install, debug conveniently, can arbitrarily adjust interactive white board size according to installation environment, and without the need to carrying out angular setting to the camera in projector again, dirigibility is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of shadow blank all-in-one of the present utility model.
