The invention relates to an optical scanning device for an appliance for reading and/or writing to optical recording media, having a movably arranged optical housing with integrally formed slide faces for holding a support which is provided with mating slide faces, can be adjusted about a virtual axis and has a scanning head, having at least one adjusting screw which is supported on the housing, acts on the support, bears against the edge of an opening made in the housing, penetrates said opening with its threaded shaft in the direction of the support with play and can move in the opening in a transverse direction, and having at least one spring means which acts on the support on the side of the slide faces which is remote from the adjusting screw and tensions said support against the slide faces of the housing, and to an appliance having the optical scanning device. It achieves the object of designing the mounting arrangement for the scanning unit in such a scanning device such that an adjusting movement is effected gently and smoothly. To this end, the adjusting screw acts on the support at a variable angle and changes its angle with respect to said support in the event of a screw movement to prompt an adjusting movement from the support.
