Description

A kind of multifunctional blackboard for education
Technical field
The present invention relates to educational aid technical field, particularly a kind of multifunctional blackboard for education.
Background technology
At present, although multimedia teaching is widely used, very multi-disciplinary teaching still needs to write largely Writing on the blackboard, such as mathematics, physics, chemistry formulation process, therefore, blackboard is still teaching work essential on classroom Tool.Traditional blackboard needs the chalk writing in artificial erasing plate face, could write again;So, the efficiency not only wiped is low, And cause the people to erase the board to suck substantial amounts of chalk dust, influence physical and mental health.
During English teaching, teacher, which usually requires to draw on blackboard, is spaced four equal lines, referred to as four line lattice.Draw four lines Lattice generally rely on the progress of man-hour manually hand-held ruler, and therefore, the line drawn can not keep uniform, and each line can not be kept parallel, shadow Ring quality of instruction.
In summary, it is necessary to provide a kind of chalk writing that can be on auto-erasing blackboard and can be automatically in blackboard The upper multifunctional blackboard for education for drawing four line lattice.
The content of the invention
The goal of the invention of the present invention is to provide a kind of multifunctional blackboard for education, for the chalk writing on auto-erasing blackboard And four line lattice are drawn on blackboard automatically, solving traditional blackboard needs artificial erasing chalk writing and four line lattice of artificial picture simultaneously Therefore the problem of very big inconvenient is brought to teaching.
To reach above-mentioned purpose, the technical solution adopted in the present invention is:
