Abstract
A laser beam scanning apparatus comprises a first mirror provided for reflecting a light path between a deflector and recording medium, a beam detecting sensor for determining a start position for recording by the beam on the recording medium, and a second mirror for guiding the beam reflected by the first mirror to the sensor. The second mirror is arranged such that the beam from the first mirror is guided to the sensor after it is reflected at least one time by said first mirror. In addition, the second mirror is arranged such that on the equation .theta..sub.2 =2.theta..sub.1 is satisfied where .theta..sub.1 and .theta..sub.2 respectively denote the inclination of the first and the second mirrors to a plane orthogonal to a surface of scanning of the beam.
