Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 139 words
A microfiche or microfilm editing device comprising a light source, a means of focussing light from the source along a copy axis through a first microfiche or microfilm held in a frame, a first x actuator connected to the frame arranged to move the frame in an x direction and a first y actuator connected to the frame arranged to move the frame in a y direction, means for driving the first actuators according to a set program, holding means for a second microfiche, said holding means arranged to hold the second microfiche in close relationship to the first microfiche or microfilm, a second x actuator and second y actuator connected to the holding means and arranged to move the holding means in x and y directions respectively, means for driving the second actuators according to another set program.
Claim 2
Dependent Claim 139 words
A microfiche or microfilm editing device comprising a light source, a means of focussing light from the source along a copy axis through a first microfiche or microfilm held in a frame, a first x actuator connected to the frame arranged to move the frame in an x direction and a first y actuator connected to the frame arranged to move the frame in a y direction, means for driving the first actuators according to a set program, holding means for a second microfiche, said holding means arranged to hold the second microfiche in close relationship to the first microfiche or microfilm, a second x actuator and second y actuator connected to the holding means and arranged to move the holding means in x and y directions respectively, means for driving the second actuators according to another set program.
Claim 3
Dependent Claim 15 words
A device as claimed in claim 1 wherein the holding means comprises a suction platen.
Claim 4
Dependent Claim 56 words
A device as claimed in claim 1 wherein the means for focussing light includes at least one light transfer block comprising a translucent block of material in which are embedded light shields arranged in a honeycombed pattern, the block being mounted and adapted to transfer light at substantially right angles to the first microfiche or microfilm.
Claim 5
Dependent Claim 28 words
A device as claimed in claim 3 wherein several light transfer blocks are located on a turrent arranged to rotate about an axis parallel to the copy axis.
Claim 6
Dependent Claim 34 words
A device as claimed in claim 4 wherein each of said light transfer blocks comforms to a standard frame size, whereby said blocks act as a mask for the image of said standard frame.
