Abstract

An electro-magnetically controllable beam deflection device for use in an optical system for deflecting a radiation beam obtained from a radiation source, in particular for use in video players. The deflection means may for example comprise a pivoting mirror, or an assembly of a plano-concave and a plano-convex lens which with their concave and convex surfaces face each other, and can perform pivoting movements at a small distance from each other. The deflection means is connected to frame by means of an integrated plastic bearing component. The bearing component has a local portion of small cross-section which under the influence of the control forces exerted on the deflection means, is relatively readily deformable. This portion may for example take the form of an integral hinge or of a thin cylindrical portion.

Dependent claims

An electro-magnetically controllable beam deflection device for use in an optical system for deflecting a radiation beam obtained from a radiation source, in particular to be used in a video player, and comprising:

a frame
a deflection means which is pivotably mounted on the frame
bearing means for pivotably supporting the deflection means by the frame, which bearing means comprise at least one integrated bearing component made of an elastic synthetic material, said bearing means having a first portion connected to the deflection means and a second portion connected to the frame, and
first and second electro-magnetic control means connected to the frame and the deflection means respectively, in the form of electro-magnetic circuits which include at least one electrical coil, the improvement wherein each integrated bearing component between said first and second portions comprises a third portion having a cross-section which is substantially smaller with respect to the other two portions, which third portion is comparatively readily deformable under the influence of the electro-magnetic control forces exerted on the deflection means.
