BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a handwritable portable roll board, and more particularly, to a portable roll board in which a writing board is wound and unwound on a roller.

Typically, a board for writing is installed so that the presenter who presides at a conference or a seminar or a training site in a school or a company can write and communicate the contents related to the presentation more effectively to the audience.

The handwriting board is divided into a chalkboard used as a chalk board and a whiteboard used as a marker pen depending on the type of writing instrument. Among them, the chalkboard has advantages of excellent writing performance, erasability, and durability, Since the chalk material is calcium carbonate, which has a detrimental effect on the human body, whiteboards that do not cause harmful powder are widely used.

Since the white board is generally formed by attaching a film that can be written on a flat board of a hard material such as wood or plastic, it is not only expensive but also has a heavy weight of the product and is installed on a wall of a classroom or a conference room And is fixed to a separate support frame disposed at one side of the space of the classroom or the conference room.

Therefore, the whiteboard according to the related art can not move to another place, or can move only a very limited distance. Therefore, when a training or a meeting is performed in a place where a whiteboard is not installed, There is an inconvenience that a writing board for writing can not be used.

In addition, since the whiteboard according to the related art is installed once in a classroom or a conference room, the space occupies much of the wall surface or space. Therefore, when the space such as the classroom or the conference room is narrow, There was an inconvenience.
