Abstract:
1. A light scanning device comprising: a light source which emits a light beam; an oscillating mirror which oscillates rotationally and reflects the light beam to be scanned over a scanning range, the scanning range including a first scanning range and a second scanning range set across a center of the scanning range; a detection unit including a light receiving face, on which the light beam is incident, to detect the light beam; and first and second stationary mirrors which reflect the light beam reflected by the oscillating mirror to the first scanning range and the second scanning range, respectively, to be incident on the light receiving face of the detection unit, wherein an incident pattern of the light beam reflected by the first stationary mirror incident on the light receiving face of the detection unit while the oscillating mirror oscillates is different from an incident pattern of the light beam reflected by the second stationary mirror incident on the light receiving face of the detection unit while the oscillating mirror oscillates, and wherein the number of the first stationary mirror is different from the number of the second stationary mirror.
