Abstract:
1. A multi-beam scanning device comprising: a subassembly comprising a bracket defining an engaging hole, the engaging hole of the bracket surrounding and contacting the engaging section of the holder, wherein the holder and the bracket define voids configured to permit rotation of the holder relative to the bracket before securing the holder to the bracket, the laser beams from the at least three light emitting points scan the recording medium in a main scanning direction while being at least one of on and off so as to form a light image having the minimum recording interval in the recording medium, the equal interval is smaller than the minimum recording interval, the at least three light emitting points are arranged such that the corresponding laser beams spots on the recording medium are arranged substantially in a line in a direction orthogonal to the main scanning direction, and any one of the laser beams is used as a clock laser beam configured to determine a timing of starting each main scanning.
