Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0014] The present invention can scan the blackboard, including: translucent glass plate 1, lighting tube 2, blackboard eraser 3, light sensor 4, engine 5, power socket (6), information storage 7, information sorting program board 8, printing device9.

[0015] The working principle of the present invention is as follows: the blackboard eraser 3 is placed on the switch, the lighting tube 2 is turned on, the light from the tube passes through the light-transmitting glass plate 1 to reveal the black characters, and the light-sensitive sensor 4 perceives the part without light transmission , convert these fonts into electrical signals, and enter the information storage 7 for storage. Then, the information enters the information organizer board 8 along with the circuit. In the program board 8, the program typesets the writing on the blackboard, edi...

Abstract

The invention discloses a blackboard capable of achieving scanning. The blackboard is composed of a light-permeable glass board (1), lighting lamp tubes (2), a blackboard eraser (3), a light sensation sensor (4), an engine (5), a power supply interface (6), an information storing device (7), an information arrangement program board (8) and a printing device (9). The working principle of the blackboard comprises the steps that under supporting of the engine (5) and lighting of the lighting lamp tubes (2), the light sensation sensor (4) senses portions (handwriting portions) which are not permeable to light, electric signals are formed, information is stored in the information storing device (7) and arranged in the information arrangement program board (8) to form a document, and then the document is printed. According to the blackboard capable of achieving scanning, the time of students is saved, the teacher listening efficiency of the students is improved, reviewing can be directly performed after a class, and the learning effect is greatly improved.

Description

technical field [0001] The invention relates to a blackboard with scanning technology, in particular to a scannable blackboard which utilizes a photosensitive sensor to scan handwriting. Background technique [0002] As education plays an increasingly important role in society, schools have spread everywhere. In school, the classroom is the place where the teacher teaches, and the blackboard is the platform on which all the knowledge of the teacher is carried. However, the teacher always has so many notes in class, students often have no time to copy the notes, or take notes but have no time to listen to the teacher's answers, which makes them confused, unable to improve their class efficiency, and wasting the time of a class. [0003] In response to the above problems, many people in the society have already had their own ideas. They have developed a projector, which uses the principle of straight-line propagation of light and light-transmitting imaging of a lens to proje...
