Embodiment Construction

[0010] In Fig. 1, the structure of the electric blackboard is to fix the miniature low-speed motor 3 on the bracket of the outer frame 1 by screws, the miniature low-speed motor 3 is connected with the groove on the outer edge of the moving roller 4 through the transmission 2, and the other side of the moving roller 4 A groove hangs on the transmission belt 5 and links to each other with the driven roller 7 . The soft plate surface 11 is fixed on the transmission belt 5 with adhesive and screws, and its roller two ends are fixed on the upper and lower frames of the outer frame 2. Soft board surface 11 is coated with certain carbon content wear-resistant rubber by fiber fabric and is made, also available wear-resistant cloth, leather or chemical fiber products that are convenient to write and wipe replace. The outside of driven roller 7 has a strip-shaped blackboard eraser 10, and its section is arc-shaped, so that blackboard eraser 11 can be made to contact with driven roller ...

Abstract

The concentratively controlled multimedia teaching system with an electric blackboard as one main part includes one electrically driven blackboard capable of erasing automatically, one projecting screen, one projector with suspended lens, one teacher's operating desk, and one concentrative control keyboard with blackboard switch, projector switch, computer switch, power switch, with all the control lines and power lines being hidden in floorboard and wall. The present invention makes it possible for the teacher to complete electric audio-visual teaching operation easily.

Description

Technical field: [0001] This application belongs to an audio-visual teaching device. Background technique: [0002] The existing multimedia teaching system includes multimedia audio-visual teaching equipment such as traditional fixed blackboards and projectors, projection screen microcomputer display screens, and microcomputer mainframes. Trouble, the electric blackboard currently used, including the outer frame, the soft horizontal backing plate, the driven wheel and the driven wheel, the micro motor, the strip eraser, etc., have the shortcomings of the board surface slipping and the wiping effect is not good, and they are not used in multimedia teaching and systems. And the flying dust will affect the audio-visual teaching equipment. Invention content: [0003] The purpose of this application is to improve the existing electric blackboard and invent a centralized control multimedia teaching system with the electric blackboard as the main body. [0004] The technical sc...
