Abstract
The projection-lens driving apparatus for use in a 3-beam projector comprises an upper plate, an upper projection-lens holder, a pair of cross links, a pair of lower projection-lens holders, a guide member, and a driving means for driving the guide member. The upper and the lower projection-lens holders are fitted to the guide member in such a way that they can be driven integrally using the driving means, thereby allowing images to coincide on a screen simply, accurately and, above all, simultaneously.
