The utility model content;

The purpose of this utility model is exactly to provide a kind of for the deficiency of prior art existence to realize the with no paper electronics instruction system of lecturing in the intelligent multi-media mode.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of electronics is lectured system, include the projection screen of lecturing with computer, being used for the induction handwriting input display screen that shows the computer displaying contents and control computer, the projector that is used for projection computer displaying contents, episcopic projector projection content, induction handwriting input display screen, projector are connected with computer data respectively.

The way of electromagnetic induction of described induction handwriting input display screen is active type way of electromagnetic induction or passive way of electromagnetic induction.

Be connected by data line between described projector and the computer or connect by WIFI mode wireless signal.

The utility model beneficial effect is: the utility model includes to lecture uses computer, the induction handwriting input display screen that is used for showing the computer displaying contents and controls computer, the projector that is used for projection computer displaying contents, the projection screen of episcopic projector projection content, induction handwriting input display screen, projector is connected with computer data respectively, the utility model is controlled computer and handwritten input information by induction handwriting input display screen, and reflex in real time on the projection screen by projector, realize with no paper instruction in the intelligent multi-media mode, the utlity model has following advantage:

1, the teacher can be completely free of the writing on the blackboard modes such as chalk and water-color paintbrush, pollutes away from traditional chalk powder, creates healthy clean and tidy teaching and academic environment;

2, the operating computer that induction handwriting input display screen can intuitive and convenient, can free handwritten input information in the explanation presentation process, input message can directly be inserted in the lecture document in the mode that true person's handwriting keeps, teacher's each teaching process and excellent performance are intactly recorded, high sensitivity, high precision is preserved and is called conveniently;

3, lecture content and can realize with no paper transmission, low-carbon environment-friendly fully;

4, can be by induction handwriting input display screen operating computer and handwritten input information, teachers and teaching notes content are enriched in the dynamic interaction performance, alleviate simultaneously the heavy work that teaching notes are made in prepare lesson, be conducive to the teacher saying the excellent performance of class hour passion, improve and lecture efficient.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1, a kind of electronics is lectured system, include computer 1, be used for performance computer 1 displaying contents and control the projection screen 4 of the induction handwriting input display screen 2 of computer 1, the general projectors 3 that is used for projection computer 1 displaying contents, episcopic projector 3 projection contents, induction handwriting input display screen 2, projector 3 are connected with computer 1 data respectively.
