Key Name Function/System
[1] SOS Mirror Condenses the incident laser light onto the SOS Sensor.
[2] G2 Lens Condenses the incident laser light, with which the Photo Conductor is
irradiated.
[3] Semiconductor Laser
■ Emits a laser light.
■ Two-beam array LD
[4] SOS Sensor Produces an SOS signal using the incident laser light.
[5] G1 Lens Corrects the condensing angle of the incident laser light.
[6] Polygon Mirror
■ Scans the incident laser light in the main scan direction and
reflects it onto the G1 Lens.
■ Four-face polygon mirror
[7] Return Mirror Reflects the laser light condensed by the G1 Lens onto the G2 Lens.
[8] G2 Lens (SOS Lens) Condenses the incident laser light onto the SOS Sensor.
