Abstract
A chalkboard writing magnifier is characterized in that a miniature camera (1) can be fastened to the chest of a teacher when the teacher gives a lesson, writings of the teacher are converted into wireless signals and transmitted to a signal receive (2) by the miniature camera during a class, the received signals are converted into electrical signals or video signals or directly magnified and projected by a projector (3), and the writings are magnified. The chalkboard writing magnifier has the advantages that incidence of myopia in students, occurring in daily teaching, can be reduced, abilities of teachers and students to write are cultivated, the problem that back-seated students cannot see or feel hard to clearly see the writings are solved, bad practice is avoided, and the quintessence of Chinese culture, calligraphy, is inherited.
Description
Technical field
Patent of the present invention relates to myopia-preventing and teaching field, specifically a kind of novel device that can amplify writing on the blackboard.
Background technology
China's myopia number is more than 400,000,000 people, and the near-sighted incidence of disease of adolescent student, children occupies second place of the world, and undergraduate rate of myopia is especially more than 90%.Myopia not only have impact on the postgraduate problem of employment of student, be also nationwide physical condition low one performance.
The number of student that the classroom of China holds is many, and the student sat in the back row is that the letter written with chalk seen clearly on blackboard is comparatively painstaking, just result in myopia in the course of time.

Summary of the invention
Patent of the present invention provides a kind of multiplying arrangement of writing on the blackboard, can reduce the myopia of student incidence of disease in daily teaching, cultivates the writing ability of teacher, student, solves the problem that student does not see writing on the blackboard, stop malpractice, be conducive to the sustainable development of student.
The technical scheme that patent of the present invention is taked is as follows:
A novel writing on the blackboard multiplying arrangement, is characterized in that: be made up of microcam (1), signal receiving device (2) and projection arrangement (3).
During teachers' instruction, can by microcam (1) front not again, his writing on the blackboard by after the writing on the blackboard absorption of upper for teacher class hour by minisize pick-up head, is converted to wireless signal image and sends to signal receiving device (2).Being converted into electronic signal or vision signal after signal is received, then by being transported to display display, or directly by projection arrangement (3) projected image, thus reaching the effect of amplifying writing on the blackboard.
The advantage of patent of the present invention is:
1, microcam (1) is simple and light, and resolution ratio of camera head is high, adopts wireless transmission, and teachers' instruction can by its front not again.
2, transmission speed is fast, and the writing on the blackboard of teacher can be amplified projection fast.
3, it was both directly amplified projection by projector equipment by writing on the blackboard, also can be exported by other signaling interface, show (as computer, TV) on different devices, flexibly and easily.
4, writing on the blackboard is more clear student to be seen, effectively suppresses the incidence of disease of myopia to a certain extent.
6, avoid student and student, being discord of relation between student and teacher, promote the development in an all-round way of student.
7, pass on and enhance and glorify the unique cultural features of a nation calligraphy.
Accompanying drawing explanation
Fig. 1 is writing on the blackboard multiplying arrangement overall diagram.
In figure, each sequence number is: 1-microcam, 2-signal receiving device, 3-projection arrangement.
Specific embodiments
During teachers' instruction, can by microcam (1) front not again, the writing on the blackboard of his upper class hour is converted to wireless signal by minisize pick-up head and sends to signal receiving device (2) by his writing on the blackboard.Be converted into electronic signal or vision signal after signal is received, or directly amplify projection by projection arrangement (3), thus reach the effect of amplifying writing on the blackboard.
Claims (3)
1. a novel writing on the blackboard multiplying arrangement, is characterized in that: be made up of microcam (1), signal receiving device (2) and projection arrangement (3).
2. a kind of novel writing on the blackboard multiplying arrangement according to claim 1, it is characterized in that: during teachers' instruction, can by microcam (1) front not again, the writing on the blackboard of his upper class hour is converted to wireless signal by minisize pick-up head and sends to signal receiving device (2) by his writing on the blackboard.
3. a kind of novel writing on the blackboard multiplying arrangement according to claim 1, is characterized in that: be converted into electronic signal or vision signal after signal is received, or directly amplify projection by projection arrangement (3), thus reach the effect of amplifying writing on the blackboard.
