Multi-partition modular camera for obtaining microfiches

Claim 2

A microfiche camera arrangement comprising: a frame; a horizontal plate having a flat upper surface provided on the frame; a light proof cover covering said horizontal plate; a shooting station arranged in said horizontal plate; a film holder unit provided under said cover and above said horizontal plate and adapted to support a photosensitive film in the vicinity of the upper surface of said plate; first and second drive means for displacing said film holder unit in an indexed fashion above said shooting station along two horizontal perpendicular axes parallel to said upper surface of said horizontal plate, so as to allow the impression on the photosensitive film of a succession of elementary images arranged according to a partition selected from various elementary image partitions, said first drive means including: a longitudinal guide connected to said horizontal plate, a transverse carriage comprising a first runner supported by said longitudinal guide, and a first driving assembly coming into engagement with said first runner so as to displace said transverse carriage along said longitudinal guide, said second drive means including: a second runner provided on said transverse carriage and capable of displacement along said transverse carriage perpendicularly to said longitudinal guide, and a second driving assembly engaging said second runner so as to displace said second runner along said transverse carriage, perpendicularly to the longitudinal guide; means for mounting said film holder unit on said second runner vertically free relative thereto; and support riders provided on said film holder unit and capable of sliding with a dry fit on the upper surface of the plate.

Claim 3

An arrangement according to claim 1 wherein each driving assembly comprises a stepwise motor and an endless screw, said endless screw engaging the associated runner.

Claim 4

An arrangment according to claim 1 wherein said film holder unit is adapted to receive two magazines which unwind and wind roll film respectively.

Claim 5

An arrangement according to claim 3 further comprising two precut microfiche magazines supported by said horizontal plate in regard of two passages provided thereto.

Claim 6

An arrangement according to claim 1 wherein in the region of said shooting station, said horizontal plate is arranged so as to define beneath its flat upper surface a channel in which a window-bearing carriage slides in a controlled manner, said carriage comprising upwardly directed saw tooth pockets defining two positions for window bearing frames capable of supporting two different windows respectively, while the window bearing frames each rest via four lateral studs in said pockets, two of these lateral studs being longer than the others, and wherein there are provided four fixed vertical studs connected to the horizontal plate, so that the resting of two of said longer lateral studs on two of said fixed vertical studs causes one of said window bearing frames to rise on a saw tooth wall from its pockets to bring it into the shooting position.

Claim 7

An arrangement according to claim 5 further comprising a shutter which is movable transversely to the window bearing carriage.

Claim 8

An arrangement according to claim 1 wherein the horizontal plate is vertically movable upon the frame and wherein the shooting station comprises a lens for taking elementary shots on the microfiche, said lens being connected to an automatic focusing assembly controlled by the position of the movable upper frame supporting the plate.

Claim 9

An arrangemeent according to claim 1 wherein an auxiliary shooting station, optical system, and title table are provided to effect title shots.

Claim 10

A microfiche camera arrangement comprising: a frame; a horizontal plate having a flat upper surface provided on said frame; a light proof cover covering said horizontal plate; a shooting station arranged in said horizontal plate; a film holder unit provided under said cover and above said horizontal plate and adapted to support a photosensitive film in the vicinity of the upper surface of the plate; first and second drive means for displacing said film holder unit in an indexed fashion above said shooting station along two horizontal perpendicular axes parallel to said upper surface of the horizontal plate, so as to allow the impression on the photosensitive film of a succession of elementary images arranged according to a partition selected from various elementary image partitions, wherein said first drive means includes: a longitudinal guide connected to said horizontal plate, a transverse carriage comprising a first runner and having a first end supported by said longitudinal guide and a second end supported by the horizontal plate, and a first driving assembly comprising a first stepwise motor and a first endless screw, said first endless screw coming into engagement with said first runner so as to displace said transverse carriage along said longitudinal guide when said first stepwise motor is actuated, and wherein the second drive means includes: a second runner provided on said transverse carriage and capable of displacement along said transverse carriage perpendicularly to said longitudinal guide, and a second driving assembly supported on said transverse carriage, comprising a second stepwise motor and a second endless screw, said second endless screw engaging said second runner so as to displace said second runner along said transverse carriage when the second stepwise motor is actuated; means for mounting said film holder unit on said second runner vertically free relative thereto; and support riders provided on said film holder unit and capable of sliding with a dry fit on the upper surface of the plate.

Claim 11

A microfiche camera arrangement comprising: a frame; a horizontal plate having a flat upper surface provided on said frame; a light proof cover covering said horizontal plate; a shooting station arranged in said horizontal plate; a film holder unit provided under said cover and above said horizontal plate and adapted to support a photosensitive film in the vicinity of the upper surface of the plate; first and second drive means for displacing said film holder unit in an indexed fashion above said shooting station along two horizontal perpendicular axes parallel to said upper surface of the horizontal plate, so as to allow the impression on the photosensitive film of a succession of elementary images arranged according to a partition selected from various elementary image partitions, wherein said first drive means includes: a longitudinal guide connected to said horizontal plate, a transverse carriage comprising a first runner and having a first end supported by said longitudinal guide and a second end supported by the horizontal plate, and a first driving assembly comprising a first stepwise motor and a first endless screw, said first endless screw coming into engagement with said first runner so as to displace said transverse carriage along said longitudinal guide when said first stepwise motor is actuated, and wherein the second drive means includes: a second runner provided on said transverse carriage and capable of displacement along said transverse carriage perpendicularly to said longitudinal guide, and a second driving assembly supported on said transverse carriage, comprising a second stepwise motor and a second endless screw, said second endless screw engaging said second runner so as to displace said second runner along said transverse carriage when the second stepwise motor is actuated; means for mounting said film holder unit on said second runner vertically free relative thereto; and support riders provided on said film holder unit and capable of sliding with a dry fit on the upper surface of the plate.
