Description

Board with board member which can move up and down {BOARD HAVING UP-DOWN MOVABLE WRITING BOARD}

The present invention relates to a blackboard capable of writing, and more particularly, the writing and image lectures can be made through a single blackboard, as well as a blackboard having a writing member capable of moving up and down to maximize the efficiency of the writing. It is about.

In general, all educational institutions and all educational institutes use the blackboard as a means to convey various information through lectures to a large number of people.

As such, most of the blackboards used as a means of communicating various information to many people were fixed blackboards.

In the case of the stationary blackboard, there is a problem that the writing efficiency of the blackboard is lowered due to different heights for each lecturer because it is fixed to the wall.

Therefore, instead of the fixed blackboard fixed to the wall, a movable blackboard that can move up and down was developed.

For example, Korean Unexamined Patent Publication No. 10-0161210 (December 01, 1998) discloses "raising and closing blackboard" is disclosed.

This lecture relates to the elevating opening and closing blackboard that can adjust the writing position of the board in the vertical direction to maximize the writing efficiency according to different bodies.

However, this technique consists of a cylinder filled with compressed gas and a plurality of pulleys to adjust the position of the writing in up and down directions, but it is possible to raise and lower the writing position, but the mechanism of the cylinder and the multiple pulleys is too complicated. As a result, the installation cost is increased, and there is a problem in that the thickness and size of the board become large because the installation space of the mechanism is required.

In addition, Korean Utility Model Publication No. 20-0236348 (registered on June 29, 2001) discloses a device for moving up and down blackboard.

This is related to the board's up and down moving device that can adjust the height of the board according to the height of the lecturer and at the same time, to reduce the manufacturing cost and ease of installation by using a simple structure mechanism.

However, such a technique can be expected to combine the vertical movement of the guide rod and bracket structure with the back of the board to enable the shanghai movement of the board, but this technology is also complicated by the mechanism structure for the shanghai movement of the board. There is a problem that costs and installation difficulties occur.

In addition, Korean Unexamined Patent Publication No. 10-2003-0064526 (published Aug. 02, 2003) discloses an "automatic elevating blackboard".

This is about an automatic lifting board that rotates a geared magnetic roller with a motor to move the board up and down. However, such a technology can raise and lower the board smoothly and quietly by using magnetic rollers and motors, and it can be expected to have an effect of accurately driving the board by preventing slipping. There are problems of excessive cost and difficulty of installation.

In the case of the above-described prior art capable of raising and lowering the blackboard, there is a problem in that manufacturing costs are increased and installation difficulties occur due to a complicated mechanism.

In addition, unlike previous education methods, current writing and video lectures are being conducted simultaneously without being limited to writing lectures, and blackboards that can only be written by conventional writing lectures cannot meet this trend. There is a problem.

Therefore, it is required to develop a blackboard that enables not only writing lectures but also video lectures.

Therefore, the object of the present invention is to adopt a simple structure using only a drive motor and wire, it is possible to reduce the manufacturing cost and easy installation, to be able to efficiently write corresponding to the body of the lecturer, parallel writing and image The present invention provides a blackboard having a writing member capable of moving up and down.

In order to achieve the above object of the present invention, the present invention provides a body that serves as a blackboard frame; A writing member capable of writing located in the main body and moving up and down; A project screen located inside the main body and located behind the writing member; A drive motor positioned inside the main body to allow the writing member to move up and down; A controller unit which receives a driving control signal of the driving motor from a remote place and controls driving of the driving motor; A wire connecting the drive motor and the writing member so that the writing member can be moved by the control of the controller unit; And it provides a blackboard having a writing member that can move up and down including a guide roller located in the upper portion of the main body to serve as a guide of the wire connecting the drive motor and the writing member.

Using a blackboard having a writing member capable of moving up and down according to the present invention, there is an advantage that it is possible to efficiently write according to the body of different lecturers, as well as lectures in parallel with the writing and the image.

In addition, the upper and lower driving mechanisms capable of vertically moving the writing member and the image device member are possible only by the driving motor and the wire, thereby reducing manufacturing costs and simplifying installation.
