Photographic printing apparatus and paper magazine for use therewith

Claim 2

A photgraphic printing apparatus for use with a paper megazine containing therein a photgraphic paper on which prints are made, said apparatus comprising: means provided on the outside of said paper magazine for indicating the paper type of a photographic paper contained in said paper magazine; means provided on said apparatus adapted register with said paper type indication means when said magazine is mounted on said apparatus for detecting said paper type; means for determining a printing condition according to said detected paper type; and means for making a color print based on the thusdetermined printing condition, thereby to obtain a color print with proper color balance and density; said paper type indication means being coded means comprised of a plurality of lugs and a plurality of recesses the particular combination of which informs said detecting means of said paper type.

Claim 3

A photographic printing apparatus in which prints are made on a photographic paper contained in a paper magazine having coded means comprised of a plurality of lugs and a plurality of recesses the particular combination of which indicates the paper type of said photographic paper, said apparatus comprising: means for reading said coded means to judge the paper type of said photographic paper when said paper magazine is mounted on said apparatus, said reading means comprising a set of microswitches one individual to each of said lugs and to each of said recesses, only some of said microswitches being actuated by said lugs or said recesses the pattern of which enables said reading means to judge the paper type; means for determining a printing condition according to said judged paper type: and means for making a color print based on the thusdetermined printing condition, thereby to obtain a color print with proper color balance and density.

Claim 4

A photographic printing apparatus in which prints are made on a photographic paper contained in a paper magazine having coded means comprised of a plurality of lugs and a plurality of recesses the particular combination of which indicates the paper type of said photographic paper, said apparatus comprising: means for reading said coded means to judge the paper type of said photographic paper when said paper magazine is mounted on said apparatus, said reading means comprising a set of microswitches one individual to each of said lugs and to each of said recesses, only some of said microswitches being actuated by said lugs or said recesses the pattern of which enables said reading means to judge the paper type; means for determining a printing condition according to said judged paper type: and means for making a color print based on the thusdetermined printing condition, thereby to obtain a color print with proper color balance and density.

Claim 5

A paper magazine used for a photographic printing apparatus of the type in which a printing condition is determined depending on the type of photographic paper, said paper magazine comprising: a housing defining a chamber in which an unexposed photographed paper is contained; and coded means provided on the outside of said housing for indicating the paper type of said photographic paper contained in said paper magazine; said coded means being comprised of a plurality of lugs and a plurality of recesses the particular combination of which is adapted to inform a said printing apparatus of said paper type.

Claim 6

A paper magazine used for a photographic printing apparatus of the type in which a printing condition is determined depending on the type of photographic paper, said paper magazine comprising: a housing defining a chamber in which an unexposed photographed paper is contained; and coded means provided on the outside of said housing for indicating the paper type of said photographic paper contained in said paper magazine; said coded means being comprised of a plurality of lugs and a plurality of recesses the particular combination of which is adapted to inform a said printing apparatus of said paper type.

Claim 7

An apparatus as defined in claim 1, said detecting means comprising a set of microswitches one individual to each of said lugs and to each of said recesses, only some of said microswitches being actuated by said lugs or said recesses the pattern of which enables said determining means to judge the paper type.
