Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 100 words
A copying apparatus for forming an image of an original on a copy medium, which comprises: a carriage adapted for reciprocating movement for supporting said original; copy processing means for forming an original image on the copy medium; means to grade a plurality of copy media bearing said original image thereon into a plurality of groups; a number of copy counter means equal to the numbeR of said grade groups for counting the number of copy mediums in each of said grade groups; and means for actuating said copy counter means in response to the reciprocating movement of said carriage.
Claim 2
Dependent Claim 100 words
A copying apparatus for forming an image of an original on a copy medium, which comprises: a carriage adapted for reciprocating movement for supporting said original; copy processing means for forming an original image on the copy medium; means to grade a plurality of copy media bearing said original image thereon into a plurality of groups; a number of copy counter means equal to the numbeR of said grade groups for counting the number of copy mediums in each of said grade groups; and means for actuating said copy counter means in response to the reciprocating movement of said carriage.
Claim 3
Dependent Claim 69 words
A copying apparatus according to claim 1, wherein said copy medium is in the form of a roll, and further comprising means for cutting the copy medium into individual copy medium sheets having a length corresponding to the length of the original, and said grading means including means for determining a plurality of size groups of copy medium sheets in accordance with the lengths of the sheets thus cut.
Claim 4
Dependent Claim 149 words
A copying apparatus according to claim 2, wherein said cutting means includes an index member movable in accordance with the length of said original, a cutting member for cutting said copy medium, and means connected with said movable index member to actuate said cutting member to cut said roll of copy medium to provide a copy medium sheet having the same length as said original, and further comprising a plurality of switch means equal in number to the number of said copy counter means, each of said copy counter means being connected with each of the respective switch means independently of each other, and cam means for actuating each of said switch means in accordance with a predetermined size of copy medium sheet, whereby each of said copy counter means records the number of copies made in each of said grade groups of predetermined sizes of copy medium sheets.
Claim 5
Dependent Claim 84 words
A copying apparatus according to claim 1 wherein said copy medium comprises pre-cut sheets and further comprising a plurality of copy medium cassettes each containing copy medium sheets of different predetermined sizes, the number of cassettes being equal to the number of grade groups and to the number of copy counter means, wherein the loading of each cassette into said apparatus actuates the copy counter means corresponding to said cassette to thereby count the number of sheets of copy medium removed from said cassette.
Claim 6
Dependent Claim 22 words
A copying apparatus according to claim 1, wherein the copy medium comprises a photosensitive material upon which a permanent image is formed.
Claim 7
Dependent Claim 18 words
A copying apparatus according to claim 5, wherein the copy medium is in the form of a roll.
Claim 8
Dependent Claim 50 words
A copying apparatus according to claim 1, wherein said copy processing means includes a photosensitive drum onto which said original image is projected to form a latent original image, means to develop said latent original image on said drum, and means to transfer said developed image onto said copy medium.
Claim 9
Dependent Claim 18 words
A copying apparatus according to claim 7, wherein said copy medium is in the form of a roll.
Claim 10
Dependent Claim 22 words
A copying apparatus according to claim 7, wherein said copy medium is in the form of pre-cut sheets of different predetermined sizes.
Claim 11
Dependent Claim 101 words
A copying apparatus comprising an original carriage for supporting an original, copy processing means for forming an image of said original on a copy medium, said copy medium being in the form of a roll, cutting means to cut said roll of copy medium in a sheet of random length corresponding to the length of the original, means to grade the cut sheets of copy medium into a plurality of groups and a number of copy counter means equal in number to the number of said grade groups for counting the number of copies made in each of said grade groups.
Claim 12
Dependent Claim 101 words
A copying apparatus comprising an original carriage for supporting an original, copy processing means for forming an image of said original on a copy medium, said copy medium being in the form of a roll, cutting means to cut said roll of copy medium in a sheet of random length corresponding to the length of the original, means to grade the cut sheets of copy medium into a plurality of groups and a number of copy counter means equal in number to the number of said grade groups for counting the number of copies made in each of said grade groups.
Claim 13
Dependent Claim 22 words
A copying apparatus according to claim 10, wherein the copy medium comprises a photosensitive material upon which a permanent image is formed.
Claim 14
Dependent Claim 50 words
A copying apparatus according to claim 10 wherein said copy processing means includes a photosensitive drum onto which said original image is projected to form a latent original image, means to develop said latent original image on said drum, and means to transfer said developed image onto said copy medium.
Claim 15
Dependent Claim 166 words
A copying apparatus according to claim 10, wherein said original carriage is linearly reciprocable between two positions, and wherein said cutting means includes an index meMber movable in accordance with the length of said original supported on said reciprocable original carriage, a cutting member for cutting said copy medium, and means connecting with said movable index member to actuate said cutting member to cut said roll of copy medium to provide a copy medium sheet having the same length as said original, and further comprising a plurality of switch means equal in number to the number of said copy counter means, each of said copy counter means being connected with each of the respective switch means independently of each other, and cam means for actuating each of said switch means in accordance with a predetermined size of copy medium sheet, whereby each of said copy counter means records the number of copies made in each of said grade groups of predetermined sizes of copy medium sheets.
