Abstract
A laser beam scanning apparatus for beam scanning a medium with the laser beam being deflected by a deflector, comprising a first mirror provided for reflecting the laser beam after deflected by the deflector and a second mirror provided for folding a light path between the first mirror and the medium in such a relationship that a first light path between the deflector and the first mirror is not intersected with a second light path between the second mirror and the medium. The first and second mirrors are arranged so as to be movable in parallel respectively for adjusting a length of scanning line on the recording medium, wherein either one of the first and second mirrors is moved when adjusting and said moved mirror has a lesser shift amount of the scanning line on the recording medium in a direction perpendicular to the scanning line as compared with the other mirror.
