automatic blackboard blackboard

Abstract

The invention provides a full-automatic writing blackboard. The full-automatic writing blackboard comprises at least one blackboard body and a frame for hanging the blackboard bodies; rotating shafts are arranged above the frame; the number of the rotating shafts is the same with that of the blackboard bodies; each rotating shaft is parallel to transverse edges of the frame; the blackboard bodies are hung on the rotating shafts through ropes; one end of each rope can be twined on the corresponding rotating shaft along with rotation of the rotating shaft; travel switches which are used for stopping the blackboard bodies from moving further are respectively arranged on inner sides of the upper and lower transverse edges of the frame; an erasing device for erasing handwritings on the blackboard bodies is arranged on the bottom of the frame; a camera capable of shooting image information on the blackboard bodies is arranged in front of the frame and is connected with a computer; and the information shot by using the camera is uploaded to an internet disk by the computer. The full-automatic writing blackboard is not required to manually move or be manually erased; lots of time is saved for teachers; and the full-automatic writing blackboard can be stopped at an optional position, and interference is reduced.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a fully automatic blackboard for blackboard writing. Background technique [0002] Most of the blackboards and blackboard erasers used in school classrooms today need to be manually moved and wiped, which is inefficient, time-consuming and labor-intensive, and also produces a lot of dust, which affects students in class, deteriorates the air environment in the classroom, and has a single function. There are many deficiencies in the blackboard and blackboard eraser commonly used in classrooms now: [0003] 1. It needs to be manually moved and wiped. When the course progress is relatively tight, the teacher often does not have a lot of time to wipe the blackboard. And the two blackboards are linked, and the positions will affect each other. [0004] 2. Ordinary blackboard erasers are inefficient and often cannot clean the blackboard well; [0005] 3. Students sometimes do not have time ...
