Claim 3

An improvement as defined in claim 1, wherein said frame identifying symbols are printed adjacently to respectively associated said frame identifying bar codes.

Claim 4

An improvement as defined in claim 2, wherein said extra symbol is "E".

Claim 5

An improvement as defined in claim 3, further comprising: sub-frame numbers disposed respectively behind a set of said number N and relevant said frame identifying bar code, and constituted by an addition of "A" to said number N, in order to identify a picture frame of a half size; and sub-frame identifying bar codes disposed adjacently to said sub-frame numbers for representing said sub-frame numbers.

Claim 6

An improvement as defined in claim 4, further comprising a plurality of DX bar codes for representing a film type, said DX bar codes printed at a predetermined pitch on a side opposite to said lateral side provided with said frame identifying bar codes and said frame identifying symbols.

Claim 7

In a photographic film having a series of a plurality of frame identifying bar codes which are printed on a lateral side of a predetermined pitch, said frame identifying bar codes representing a respective symbol identifying a picture frame to be formed by photography, said frame identifying symbols including serial numbers at least from "1" to "N" assigned serially to N frames to be arranged from a film leader end towards a film trailer end, and an extra symbol assigned to an extra frame disposed after said frame numbered as said N, where said N is a standardized number of available frames for exposure associated with a length of said photographic film, an improvement comprising: a bar code disposed behind said frame identifying bar code associated with said extra symbol for representing a final symbol, said final symbol bar code signaling that a bar code preceding thereto represents said frame identifying bar code associated with said extra symbol.

Claim 8

In a photographic film having a series of a plurality of frame identifying bar codes which are printed on a lateral side of a predetermined pitch, said frame identifying bar codes representing a respective symbol identifying a picture frame to be formed by photography, said frame identifying symbols including serial numbers at least from "1" to "N" assigned serially to N frames to be arranged from a film leader end towards a film trailer end, and an extra symbol assigned to an extra frame disposed after said frame numbered as said N, where said N is a standardized number of available frames for exposure associated with a length of said photographic film, an improvement comprising: a bar code disposed behind said frame identifying bar code associated with said extra symbol for representing a final symbol, said final symbol bar code signaling that a bar code preceding thereto represents said frame identifying bar code associated with said extra symbol.

Claim 9

An improvement as defined in claim 6, wherein said frame identifying symbols are printed adjacently to respectively associated said frame identifying bar codes.

Claim 10

An improvement as defined in claim 7, wherein said extra symbol is "E".

Claim 11

An improvement as defined in claim 8, wherein said final symbol is "EA".

Claim 12

An improvement as defined in claim 9, wherein said final symbol "EA" is printed adjacently to said final symbol bar code.

Claim 13

An improvement as defined in claim 10, further comprising: sub-frame identifying symbols disposed respectively behind a set of said number N and relevant said frame identifying bar code, and constituted by an addition of "A" to said number N, in order to identify a picture frame of a half size; and sub-frame identifying bar codes disposed adjacently to said sub-frame identifying symbol for representing said sub-frame identifying symbols.

Claim 14

An improvement as defined in claim 11, further comprising a plurality of DX bar codes for representing a film type, said DX bar codes printed at a predetermined pitch on a side opposite to said lateral side provided with said frame identifying bar codes and said frame identifying symbols.

Claim 15

In a photographic film having a series of a plurality of frame identifying bar codes which are printed on a lateral side at a predetermined pitch, said frame identifying bar codes representing a respective symbol identifying a picture frame to be formed by photography, said frame identifying symbols including serial numbers at least from "1" to "N" assigned serially to N frames to be arranged from a film leader end toward a film trailer end, and an extra symbol assigned to an extra frame disposed after said frame numbered as said N, where said N is a standardized number of available frames for exposure associated with a length of said photographic film, an improvement comprising: a bar code disposed in at least one of beginning, intermediate and ending positions of said series of said frame identifying bar codes for representing said standardized number N of available frames for exposure.

Claim 16

In a photographic film having a series of a plurality of frame identifying bar codes which are printed on a lateral side at a predetermined pitch, said frame identifying bar codes representing a respective symbol identifying a picture frame to be formed by photography, said frame identifying symbols including serial numbers at least from "1" to "N" assigned serially to N frames to be arranged from a film leader end toward a film trailer end, and an extra symbol assigned to an extra frame disposed after said frame numbered as said N, where said N is a standardized number of available frames for exposure associated with a length of said photographic film, an improvement comprising: a bar code disposed in at least one of beginning, intermediate and ending positions of said series of said frame identifying bar codes for representing said standardized number N of available frames for exposure.

Claim 17

An improvement as defined in claim 13, wherein said frame identifying symbols are printed adjacently to respectively associated said frame identifying bar codes.

Claim 18

An improvement as defined in claim 14, wherein said extra symbol is "E".

Claim 19

An improvement as defined in claim 15, further comprising: sub-frame numbers disposed respectively behind a set of said number N and relevant said frame identifying bar code, and constituted by an addition of "A" to said number N, in order to identify a picture frame of a half size; and sub-frame identifying bar codes disposed adjacently to said sub-frame numbers for representing said sub-frame numbers.

Claim 20

An improvement as defined in claim 16, further comprising a plurality of DX bar codes for representing a film type, said DX bar codes printed at a predetermined pitch on a side opposite to said lateral side provided with said frame identifying bar codes and said frame identifying symbols.
