Photographic printing apparatus

Claim 2

A photographic printing apparatus in which an exposure value required to print a frame image of a photographic film on a front surface of a printing paper is manually corrected, comprising: means for manually inputting printing data to said photographic printing apparatus, said printing data being necessary for processing said frame image on said printing paper; and a storage medium for recording said manually inputted printing data and for recording simultaneously corresponding frame number data which is automatically read from said photographic film when the printing data is manually inputted to said photographic printing apparatus by said inputting means, said storage medium being detachably set in said photographic printing apparatus, whereby said printing data and frame number data recorded in said storage medium are subsequently recorded on a rear surface of said printing paper directly opposite the corresponding printed frame image after said printing paper has been developed.

Claim 3

A photographic printing apparatus according to claim 1, wherein said printing data includes exposure correction data used to obtain a corrected exposure value required for printing.

Claim 4

A photographic printing apparatus according to claim 2, further including storage/input means for storing said data in said storage medium inputted to said photographic printing apparatus.

Claim 5

A photographic printing apparatus according to claim 3, wherein said storage medium comprises a paper tape, and said storage/input means comprises a paper tape puncher.

Claim 6

A photographic printing apparatus according to claim 3, wherein said storage medium comprises one of a magnetic tape, a floppy disk, an optical disk, an optical memory and a semiconductor memory.

Claim 7

A photographic printing apparatus according to claim 3, further including a control means for controlling the exposure value to an optimum value on the basis of the data input through said data inputting means.

Claim 8

A photographic printing apparatus according to claim 6, wherein said control means is arranged such that it controls an operation of said storage/input means.

Claim 9

A photographic printing apparatus according to claim 1, wherein said data inputting means comprises a keyboard.

Claim 10

A photographic printing apparatus according to claim 1, further comprising a reading head to read both said printing data and said corresponding frame number data in the storage medium, and a writing head to record said printing data and said corresponding frame number data on said rear surface of the printing paper.

Claim 11

A photographic printing apparatus for manually correcting the exposure value required for printing a frame image of a photographic film on a front surface of a printing paper, comprising: a storage medium for storing printing data and corresponding frame number data to identify the frame image, being detachably set in said photographic printing apparatus; means for manually inputting said printing data to said photographic printing apparatus, said printing data being necessary for processing said frame image on said printing paper; and storage/input means for simultaneously storing said printing data which is manually inputted and said corresponding frame number data which is automatically read in the storage medium at the same time of manually inputting said printing data to said photographic printing apparatus, whereby said printing data stored in said storage medium is subsequently recorded on a rear surface of said printing paper directly opposite the corresponding printing frame image after said printing paper has been developed.

Claim 12

A photographic printing apparatus for manually correcting the exposure value required for printing a frame image of a photographic film on a front surface of a printing paper, comprising: a storage medium for storing printing data and corresponding frame number data to identify the frame image, being detachably set in said photographic printing apparatus; means for manually inputting said printing data to said photographic printing apparatus, said printing data being necessary for processing said frame image on said printing paper; and storage/input means for simultaneously storing said printing data which is manually inputted and said corresponding frame number data which is automatically read in the storage medium at the same time of manually inputting said printing data to said photographic printing apparatus, whereby said printing data stored in said storage medium is subsequently recorded on a rear surface of said printing paper directly opposite the corresponding printing frame image after said printing paper has been developed.

Claim 13

A photographic printing apparatus according to claim 10, wherein said printing data includes exposure correction data used to obtain a corrected exposure value required for printing said image frame.

Claim 14

A photographic printing apparatus according to claim 11, wherein said storage medium comprises a paper tape, and said storage/input means comprises a paper tape puncher.

Claim 15

A photographic printing apparatus according to claim 11, wherein said storage medium comprises one of a magnetic tape, a floppy disk, an optical disk, an optical memory and a semiconductor memory.

Claim 16

A photographic printing apparatus according to claim 10, wherein said data inputting means comprises a keyboard.

Claim 17

A photographic printing apparatus according to claim 10, further including a control circuit for controlling the exposure value to an optimum value on the basis of the data input through said data inputting means.

Claim 18

A photographic printing apparatus according to claim 15, wherein said control circuit is arranged such that it controls an operation of said storage/input means so as to store said data in said storage medium.

Claim 19

A photographic printing apparatus according to claim 10, further comprising a reading head to read both said printing data and said corresponding frame number data in the storage medium, and a writing head to record said printing data and said corresponding frame number data on said rear surface of the printing paper.
