Abstract

The invention relates to a scanning device for optical discs, having an adjustable scanning unit tensioned against a carrier with a spring. For minimizing the structural space for the spring and avoiding separate fixing elements, the spring is formed as a dip spring, having an elongated spring limb and a bearing limb formed transversely with respect to the latter, which clip spring impinges at one of its ends with the bearing limb on the carrier with a contact force and is supported at its other end at a distance from the impingement location on the housing.
