摘要	An optical scanning device has a housing in which a duct surrounds a space from the deflector and its circumference to an outlet in insulation from the optical system, and guides gas from an inlet to the space. A positioning member is shaped as a pillar that protrudes from the floor of the duct towards the deflector and has a tip to contact with the deflector to locate the rotation axis of the polygon mirror at a position relative to the housing. The positioning member further limits a clearance between an outer surface of the deflector and the floor to secure therein a flow path of the gas.
其他摘要	光学扫描装置具有壳体，在该壳体中导管围绕从偏转器及其周边到与光学系统绝缘的出口的空间，并将气体从入口引导到该空间。定位构件的形状为支柱，该支柱从管道的底部朝向偏转器突出，并且具有与偏转器接触的尖端，以将多面镜的旋转轴定位在相对于壳体的位置。定位构件还限制了偏转器的外表面与地板之间的间隙，以在其中固定气体的流动路径。
