Abstract
An optical scanner comprises a light source, a reflection mirror, deflection device, and an f·θ lens fixed to a plate-shaped bracket. The optical scanner is characterized in that a luminous flux emitted from the light source is guided to the deflection device by the reflection mirror and the luminous flux deflected by the deflection device is guided to the f·θ lens, a light source optical path from the light source to the reflection mirror is arranged to be tilted with respect to a plane which is drawn by an optical axis of a scanning optical path led to the f·θ lenses deflected by the deflection device, and the light source optical path is arranged on one side across the plane drawn by the optical axis of the scanning optical path, and the plate-shaped bracket of the f·θ lens is arranged on the other side.

An optical scanner comprising a light source, a reflection mirror, a deflection device, and an f·θ lens fixed to a plate-shaped bracket, wherein:
- a luminous flux emitted from the light source is guided to the deflection device by the reflection mirror and the luminous flux deflected by the deflection device is guided to the f·θ lens;
- a light source optical path from the light source to the reflection mirror is arranged to be tilted with respect to a plane which is drawn by an optical axis of a scanning optical path led to the f·θ lens deflected by the deflection device;
- and
- the light source optical path is arranged on a lower side across the plane drawn by the optical axis of the scanning optical path and the plate-shaped bracket of the f·θ lens is arranged on an upper side.
