Body is put down, and is kept off before blackboard, is accepted projecting apparatus and is thrown the image of coming.And projector curtain is for a long time in use, curtain ontology
Surface can accumulate the dusts such as many chalk dusts, influence the clarity of image.It, generally can not be into but due to the structure of curtain ontology
Row is unpicked and washed.Projector curtain itself exists in wall, cannot arbitrarily move；Sometimes image is not sufficiently stable or writing is unclear
Clear, conventional way is manually to adjust the elevation angle of projecting apparatus, this often causes the unintelligible or even ghost image of image, needs
Repeatedly adjustment, until clear.
From the structure of above-mentioned projector curtain current projector curtain inconvenience is can be seen that unpick and wash, can not dedusting, dust
Long-term accumulation can damage the effect that curtain receives image, can also influence the health of student；Due to the sky at dais before classroom
Between it is limited, when projector curtain pulls down, part blackboard can be blocked, be unfavorable for using while curtain and blackboard, influence to impart knowledge to students
Effect；Image definition is adjusted using projector angles, angle adjustable is limited in scope, and adjustment is time-consuming and laborious, and effect is not
It is satisfactory.In addition, classroom is as student's gathering place, when fire incident occurs, projector curtain readily becomes oxidizer,
Aggravate the sprawling degree of fire.Therefore, existing projector curtain receives image and is adjusted by projecting apparatus substantially without dust collection capacity
Clarity, it is difficult to operate, area is larger, easily causes the harm of bigger when fire after burning, influences the security of the lives and property of people.
