Abstract:
A raster output scanner comprising: a raster output scanner housing; a replaceable collimator assembly having a laser diode for emitting a light beam; said collimator assembly collimating and sending the light beam from said laser diode to said raster output scanner housing; said raster output scanner housing having an opening to receive said light beam from said collimator assembly; a first securing means being located on said raster output scanner housing;a second securing means for engaging said first securing means to secure said collimator assembly to said raster output scanner housing; said second securing means being located on said collimator assembly; said raster output scanner housing having a first aligning means; said collimator assembly having a second aligning means for engaging said first aligning means; said first aligning means being so constructed and arranged to allow said second engaged aligning means to tangentially move to provide a fine alignment between said first and said second securing means; and said collimator assembly and said raster output housing being so constructed and arranged that once secured to each other, the light beam from said collimator assembly travels on an optical path in said raster output scanner housing.
