<p>A laser array device is disclosed. The laser array device according to the present invention comprises a laser point ball including; an irradiation unit which is used to form a coordinate point to arrange an image in a screen and irradiates a laser for forming a coordinate point; and a body in which a light source of the irradiated laser is received. The laser array device comprises a housing including; an upper holder which supports one side of the laser point ball by including an upper opening hole which is opened to expose the irradiation unit to the outside; and a lower holder which supports the other side of the laser point ball. The laser point ball is rotated while being supported on the upper holder and the lower holder. According to the present invention, the laser point ball is rotated while being supported on the upper holder and the lower holder. The laser point ball is formed into a ball type and is three-dimensionally rotated. Therefore, the control of the coordinate point displayed on the screen can be executed easily.</p> |
