Photographic printer, video image and film image printing apparatus

Claim 2

A photographic printer for making prints according to alternative video image printing and film negative image printing systems, said printer comprising: a CRT for outputting an illuminated raster area on a phosphor screen according to an electron beam; a video image printing system for making a print of a video image displayed on said phosphor screen of said CRT; a film negative image printing system using said CRT as an illumination light source for making a print of an image frame of a film negative; and deflection angle changing means for changing an angle of deflection of said electron beam of said CRT such that, for said film negative image printing system, a raster area on said phosphor screen is varied to a size smaller and a raster density greater than a size and density of a raster area for said video image printing system, said raster area for said film negative image printing system corresponding to the size of said single image frame of said film negative for making said print of said image frame of said film negative.

Claim 3

A photographic printer as defined in claim 1, further comprising a light shielding tube for preventing ambient light from falling onto the phosphor screen of the CRT and for limiting light from affecting a print produced with said video image printing system, said light shielding tube being removably disposed on a working table when said video image printing system is used.

Claim 4

A photographic printer as defined in claim 1, wherein said deflection angle changing means includes means for changing said angle of deflection of an electron beam of said CRT in accordance with an indicated film negative format.

Claim 5

A photographic printer as defined in claim 3, further including a negative carrier which includes means for indicating said film negative format.

Claim 6

A photographic printer as defined in claim 4, said indicating means including code notches provided on said negative carrier.

Claim 7

A photographic printer as defined in claim 1, wherein said deflection angle changing means includes means for changing said angle of deflection of said electron beam to form a marginal raster area larger than said raster area of said film negative image system, said marginal raster area having a border whose luminance gradually decreases in a direction away from a center of said marginal raster area.

Claim 8

A photographic printer as defined in claim 2, wherein said deflection angle changing means includes means for changing said angle of deflection of said electron beam to form a marginal raster area larger than said raster area of said film negative image system, said marginal raster area having a border whose luminance gradually decreases in a direction away from a center of said marginal raster area.

Claim 9

A photographic printer as defined in claim 3, wherein said deflection angle changing means includes means for changing said angle of deflection of said electron beam to form a marginal raster area larger than said raster area of said film negative image system, said marginal raster area having a border whose luminance gradually decreases in a direction away from a center of said marginal raster area.

Claim 10

A photographic printer as defined in claim 4, wherein said deflection angle changing means includes means for changing said angle of deflection of said electron beam to form a marginal raster area larger than said rater area of said film negative image system, said marginal raster area having a border whose luminance gradually decreases in a direction away from a center of said marginal raster area.

Claim 11

A photographic printer as defined in claim 5, wherein said deflection angle changing means includes means for changing said angle of deflection of said electron beam to form a marginal raster area larger than said raster area of said film negative image system, said marginal raster area having a border whose luminance gradually decreases in a direction away from a center of said marginal raster area.

Claim 12

A photographic printer having as alternative printing systems, a CRT image printing system for making a print of a video image displayed on a phosphor screen of a CRT by projecting the video image on photographic paper, and a photographic film negative image printing system using said CRT as an illumination light source for alternatively making a print of an image frame of a film negative, said photographic printer comprising: a table stationarily disposed under the photographic paper; a CRT unit disposed below said table and housing the CRT; a film negative carrier removably disposed on said table for holding said film negative when said photographic film negative image printing system is used; a mirror box, removably disposed between said table and said CRT unit when said photographic film negative image printing system is used, for collecting and directing the light emitting from said CRT toward said film negative on said film negative carrier; and means for driving said CRT to emit white light according to a raster area smaller in size and greater in density than a raster area when said CRT image printing system is used, for illuminating said film negative when said photographic film negative image printing system is used.

Claim 13

A photographic printer having as alternative printing systems, a CRT image printing system for making a print of a video image displayed on a phosphor screen of a CRT by projecting the video image on photographic paper, and a photographic film negative image printing system using said CRT as an illumination light source for alternatively making a print of an image frame of a film negative, said photographic printer comprising: a table stationarily disposed under the photographic paper; a CRT unit disposed below said table and housing the CRT; a film negative carrier removably disposed on said table for holding said film negative when said photographic film negative image printing system is used; a mirror box, removably disposed between said table and said CRT unit when said photographic film negative image printing system is used, for collecting and directing the light emitting from said CRT toward said film negative on said film negative carrier; and means for driving said CRT to emit white light according to a raster area smaller in size and greater in density than a raster area when said CRT image printing system is used, for illuminating said film negative when said photographic film negative image printing system is used.

Claim 14

A photographic printer as defined in claim 11, wherein said mirror box is shaped in the form of a frustum pyramid having mirrored inside walls.

Claim 15

A photographic printer as defined in claim 11, further comprising two light shielding tubes for preventing ambient light from falling onto the phosphor screen of the CRT and for limiting light from affecting a print produced with said video image printing system, said two light shielding tubes being removably disposed on and under the table when said video image printing system is used.
