Description
Technical field
The utility model relates to electronic applications, refers to a kind of laser pen large screen projection device especially.
Background technology
At present, projector is indispensable picture output device in modern multimedia meeting room and multi-media classroom, its effect in MultiMedia Field is that Nonlinear magnify is appreciated for people, be common CRT and LCD TV incomparable, it the VGA signal of traditional vision signal and computer curtain can be appreciated for people by projecting after converting interface and.Pursue in high-level efficiency, allegro modern handle official bussiness in today, projector can see its figure everywhere as Novel office equipment user.Projector not only can be applied to temporary meeting, technology lecture, network center, Command center, can also be connected with computing machine, workstation etc., or video recorder of plugging into, televisor, video disc player and real object exhibition booth etc., can say that it is a kind of application large-screen image equipment very widely.
Existing projector wireless laser pen is that a new patent electronic product specially for computing machine and multimedia projector design is very general in the use of the developed countries such as America and Europe; It is except possessing the mapping function of conventional laser teacher's pointer, can also by pressing the upper and lower page-turning button of laser pen simply, and wirelessly directly Remote computer or multimedia overhead projector equipment realize free page turning and the arbitrarily demonstration of electronic document.Wireless laser pen can speaker from computer side thorough liberation out user need not keep on computing machine side always.When speaker at electronic instruction, PowerPoint and informational lectures time, when needing remarks to illustrate for key content, only need gently press red laser point with hand just can be mapped on the document content screen that you require emphasis, can save when speaker explains key content at every turn and audience " makes unwarranted remarks " or to go to its " intimate contact " before projection screen arduous, simultaneously the speaker's page that also only correlation function button need be given directions gently just electronic manuscript can be turned over will to give a lecture to you up and down 360 degree unrestrained.No matter you in classroom, which corner of lecture hall, or meeting room below and pay attention to the class people and make On-the-spot Interaction, only need speaker to gently press the upper and lower page turning key of wireless page turning laser pen, the picture that speaker wants will appear on screen automatically.
Along with teaching and the continuous expansion of parliamentary dimension, common single curtain projection can not meet the demand of human development, in the large-scale teaching needing multiple projection screen all around or meeting room, although speechmaker holds the free page turning that manual laser pen can control shadow document, but when needing remarks to illustrate for key content, to project on main screen the screen of dead ahead (be generally be main screen) to produce speck emphasis indicate with regard to needing to hold manual laser pen, and other screens not having laser pen to project, then can not produce hot spot.For needing the people that attends a lecture seeing rear and left and right screen, main screen of must turning one's head back find manual laser pen project speck on main screen, just can know where speaker says, even sometimes lecturee finds and where does not know speck for a long time, the people's energy attended a lecture so is all placed on searching laser pen and is incident upon on the speck of main screen, cause or do not catch up with the thinking of speaker, or miss the emphasis that speaker points out; Final result does not know speaker institute cloud exactly.Present very general phenomenon that Here it is, it is a wild boast that the speaker on platform says, the people attended a lecture under platform scarcely knows what one has said.
Utility model content
In view of this, the purpose of this utility model is to propose a kind of laser pen large screen projection device, can solve laser pen in prior art and project on screen, only have this screen to have hot spot to show, the defect that other screens do not have.
Based on the laser pen large screen projection device that above-mentioned purpose the utility model provides, comprise manual laser pen, at least one automatic laser pen, main screen, at least one screen, at least two projector, 4 quadrant detector and at least one stepper motor; Described main screen side is provided with described manual laser pen, described projector and described 4 quadrant detector, and described manual laser pen is for projecting to speck on described main screen, and described 4 quadrant detector detects the speck on described main screen; Needed for described projector, content is on described main screen, and described 4 quadrant detector is connected with described stepper motor;
Described screen side is provided with described projector, described stepper motor and described automatic laser pen, and described stepper motor is connected with described automatic laser pen, and described automatic laser pen can be made to rotate; And described stepper motor is connected with the 4 quadrant detector of described main screen side; Meanwhile, content needed for this projector on the screen.
Alternatively, described main screen is identical with the quantity of described projector with the total quantity of described screen.
Alternatively, described stepper motor is identical with the quantity of described automatic laser pen.
Alternatively, described 4 quadrant detector is integrated on described projector.
Alternatively, described stepper motor and described automatic laser pen are integrated on described projector.
As can be seen from above, the laser pen large screen projection device that the utility model provides, by being provided with manual laser pen, projector and 4 quadrant detector in main screen side, manual laser pen is for projecting to speck on main screen, speck on 4 quadrant detector detection main screen, 4 quadrant detector is connected with stepper motor; Screen side is provided with projector, stepper motor and automatic laser pen, and stepper motor is connected with automatic laser pen, and automatic laser pen can be made to rotate; And stepper motor is connected with the 4 quadrant detector of main screen side.Thus described laser pen large screen projection device can realize the projection situation that multiple screen can show same laser pen simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of laser pen large screen projection device in the utility model embodiment.
Embodiment
