The cleaning liquid is supplied to the cotton.

A retraction drive means is provided so as to be attached to and detached from the erasing member assembly writing member including a brush and a wiper.

As such, when a TV having a relatively large screen size is exposed at one corner of the front side of the conventional blackboard, the environment beautifies the classroom, and the TV reduces the space for posting other educational materials.

In addition, the biggest disadvantage is that the TV is biased in one front corner, so that a blind spot is not visible.

Therefore, not only the educational effect was significantly lowered, but also the discomfort caused by the dissatisfaction and displacement of the students in blind spots.

The present invention solves the above problems and recently moved to the front when necessary in a state where the wall TV, which has been significantly thinned due to the development of screen thickness, is stored on one side of the writing surface such as an auxiliary blackboard, so that the audiovisual education can be carried out quickly and without blind spots. It is to provide an educational board to make it easier.

It is another object of the present invention to provide an educational blackboard that facilitates slide operation and improves indoor environment beautification.

In order to achieve this object, the present invention is located on the front wall surface, such as the lecture room, the frame portion 10 consisting of the upper frame body 11, the lower frame body 12 and the side frame body 13,

The main blackboard 20 is installed toward the front surface of the frame 10,

In the opening and closing blackboard provided with the auxiliary blackboard 30 is guided to the rail groove 14 formed in the upper frame body 11 and the lower frame body 12 to be moved to the position of the main blackboard 20,

The brackets 40 are fixedly attached to both sides of the back surface T selected from any one of the auxiliary blackboards 30, and

Fastening the hangers 41 toward both sides up and down of the brackets 40,

The rollers 42 are rotatably provided at the ends of the hangers 41 so as to be slidably moved along the rail grooves 14 of the frame part 10.

According to the configuration of the present invention, any one of the plurality of auxiliary blackboards 30 provided on both sides of the main blackboard 20 can be selected as a wall (T) capable of viewing the image.

Therefore, the TV can be placed in the center of the front of the room if necessary, simply decorating the environment beautification of the interior of the room, so that all students in the room without the blind spot can access various materials and video education contents connected to the computer in the optimal environment. You can watch.
