ABSTRACT:
Photocomposing apparatus comprising a projection system for projecting optical images selected from a character matrix onto a photosensitive recording member by way of a mirror which is rotatable to displace projected images with respect to the recording member. The projection system includes a wide-angle lens for focussing the optical images onto a substantially flat image plane coincident with the recording member, and a zoom lens system arranged to produce a first fixed image which provides, by the action of the rotatable mirror, an object for the wide-angle lens which is selectively positionable in a substantially flat object plane.
