Horizon projector / Projector

As the number of people who enjoy digital culture sush as games, films, internet and music is growing fast, the using of protable video instrument is also increased. Therefore, I propose a new projector revised major problems.

The horizon projector keeps horizontality constantly.
The cylinder-shaped center of gravity keeps horizontality even on the inclined place so that you can get rid of the problem from controlling its horizontality when you set it up.

The horizon makes it easy to regulate its projection angles.
It can control the height and angles of projecting through the widening angles by the slope of handles at the same time.
