Abstract
A projection apparatus includes: multiple scanning optical systems each including: a light source to emit a light beam; a scanner to deflect the light beam from the light source to form a scanning light beam; a magnifier including: at least one positive lens; and at least one negative lens, to magnify a scanning angle of the scanning light beam from the scanner; and a board having: a mounting surface; and a perpendicular line perpendicular to the mounting surface, the board mounting multiple scanners including the scanner of the multiple scanning optical systems on the mounting surface. Multiple scanning light beams have the scanning light beam from the scanner are arranged in rotational symmetry with respect to the perpendicular line with different angles in a plane of the mounting surface of the board, and the multiple scanning optical systems project the multiple scanning light beams to different regions from each other.
