Abstract
The invention relates to an optical scanning device ( ) for scanning an information carrier ( ), such as a CD or DVD. The scanning device comprises a radiation source ( ), a lens system ( ) with an optical axis ( ) for focussing a radiation beam ( ) supplied by the radiation source into a scanning spot ( ) on the information carrier, and a focussing actuator ( ) for displacing the lens system with respect to a base part ( ) of the scanning device in a direction parallel to the optical axis. The lens system is elastically suspended with respect to a suspension member ( ) of the scanning device, said suspension member being arranged next to the lens system, viewed in a direction transverse to the optical axis. The scanning device further comprises an adjusting device ( ) with a first part ( ) and a second part ( ), which can be displaced with respect to said first part to set an inclination of the lens system with respect to the information carrier about two mutually perpendicular inclination axes ( ). According to the invention, the second part of the adjusting device is provided on the suspension member, while the first part of the adjusting device is provided on a supporting member ( ) which is arranged next to the lens system, viewed in a direction transverse to the optical axis. In this manner, a structural height of the optical scanning device, viewed in a direction parallel to the optical axis, is substantially not influenced by the presence of the adjusting device, so that said structural height can be reduced substantially. The optical scanning device in accordance with the invention can be used in an optical disc player according to the invention.
