ブームプリンター。 In a laser beam printer that has at least a semiconductor laser unit, an optical lens, and a polygon mirror, and each of the above devices constitutes an integrated scanner unit, the scanner unit has a narrow width only at the laser beam emission part. It has a slit-shaped opening, leaves an entrance part and an exit part for the laser around the polygon mirror, is surrounded by a shielding member, and is characterized by providing an obstacle to attenuate the wind inside the scanner unit.
