ABSTRACT:
An optical scanning device comprises a beam source unit having a laser source, and a housing on which the beam source is mounted. The housing accommodates optical components through which a laser beam from the beam source unit is applied to the surface of an object thereby to optically scan the object surface. The housing includes a base plate carrying the optical components and a side wall provided with a beam source mounting portion which enables the beam source mounting portion which enables the beam source unit to be mounted and demounted on and from the side wall by a vertical movement of the beam source unit. Alternatively, the side wall of the housing is provided with a locating portion which provides a locating surface parallel to the optical axis of the laser beam.
