ABSTRACT:
A microfiche or microfilm editing device in which a microfilm or microfiche to be edited is supported on a frame arranged to be driven in an `x` and `y` axis directions according to a program, the movements being relative to a copy axis. Also movable in relation to the copy axis is a microfiche holding means arranged to be driven by actuators in a similar fashion to the first microfiche or microfilm and according to a further program. In order to illuminate the image to be transferred to the first film to the second film a light source condenser and at least one light transfer block is arranged to project light along the copy axis. Several light transfer blocks may be mounted on a rotatable turret so that different blocks may be provided for different microfiche or microfilm standards.
The editing device is arranged so that microfiches can be updated according to a set program or alternatively microfilm can be changed to microfiche or microfiches and one standard can be changed to microfiches of another standard.
