Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
211 words
A copying apparatus comprising: image reading means (102) for optically reading an original and for
outputting image signals corresponding to the original; image processing means (301) for processing the image signals supplied from
said image reading means (102) so that
image signals are converted into image data and for outputting image data; image forming means (104) for forming an image corresponding to the image
data supplied from said image processing means on a recording sheet; original determination means (400) for determining whether a rank of
certainty that the original is a predetermined special original is a first rank or a
second rank lower than the first rank; information adding means for adding predetermined information to the
recording sheet, using a special ink, on which the image is formed by said image forming means when
the determination result obtained by said original determination means is the second
rank; characterized by prohibiting means for prohibiting the image corresponding to the original
from being formed on the recording sheet when the determination result obtained by
said original determination means is the first rank; wherein predetermined information is added in a separate step from an image forming step carried out by said image forming means to the
recording sheet on which the image is formed.
Claim 2
Dependent Claim
23 words
The copying apparatus as claimed in claim 1, wherein said information
adding means (112) is located separately from said image forming means
(104).
Claim 3
Dependent Claim
32 words
The copying apparatus as claimed in claim 1, further comprising a reversing path (603) for reversing the recording sheet, wherein the predetermined information is added onto the backside of the
recording sheet.
Claim 4
Dependent Claim
259 words
The copying apparatus as claimed in claim
1, wherein said original determination means (400) comprises: storage means (402) for storing reference data
representing a characteristic of the predetermined
special original; characteristic extracting means (401) for
generating, based on the image signals from said image
reading means (102), characteristic data representing a
characteristic of the original; comparing means (403) for comparing the
characteristic data generated by said characteristic
extracting means (401) and the reference data in said storage
means (402) with each other and for generating a similarity
value representing a degree of similarity between the
characteristic data and the reference data; first determination means (404) for determining
whether or not the similarity value from said comparing
means is equal to or greater than a first reference
similarity value; and second determination means (404) for determining
whether or not the similarity value from said comparing
means (403) is equal to or greater than a second reference
similarity value less than the first reference
similarity value, wherein when said first determination
means (404) determines that the similarity value is equal to
or greater than the first reference similarity value,
said original determination means (400) determines that the
rank of certainty is the first rank, when said first
determination means (404) determines that the similarity value
is less than the first reference similarity value and
when the second determination means (404) determines that the
similarity value is equal to or greater than the second
reference similarity value, the original determination
means (400) determines that the rank of certainty is the first
rank.
Claim 5
Dependent Claim
167 words
The copying apparatus as claimed in claim
1, wherein said original determination means (400) comprises: first determination means (404) for determining, in
accordance with a first method, whether or not the
original read by said image reading means (102) is the same as
the predetermined special original; and second determination means (404) for determining in
accordance with a second method, whether or not the
original read by said image reading means (102) is the same as
the predetermined special original, when both said first
and second determination means (404) determines that the
original is the same as the predetermined special
original, said original determination means (400) determines
that the rank of certainty is the first rank, when said
first determination means (404) determines that the original
is the same as the special original and when said second
determination means (404) determines that the original is not
the same as the special original, said original
determination means (400) determines that the rank of
certainty is the second rank.
Claim 6
Dependent Claim
33 words
The copying apparatus as claimed in claim
1, wherein the information to be added to the recording
sheet by said information adding means (112) is a mark
representing information identifying said copying
apparatus.
Claim 7
Dependent Claim
59 words
The copying apparatus as claimed in claim
1, wherein the information to be added to the recording
sheet by said information adding means (112) is formed of a
plurality of marks, said plurality of marks being
arranged so that at least one mark is located in an area
corresponding to a minimum sized special original on the
recording sheet.
Claim 8
Dependent Claim
33 words
The copying apparatus as claimed in claim
1 further comprising: display means for displaying a message
indicating that the image forming is prohibited when
said prohibiting means prohibits the image from being
formed.
Claim 9
Dependent Claim
46 words
The copying apparatus as claimed in claim
1 further comprising: history recording means (210) for, when said
determination means determines that the rank of
certainty is either the first rank or the second rank,
recording information regarding an image forming process
corresponding to the determination result.
Claim 10
Dependent Claim
32 words
The copying apparatus as claimed in claim
5, wherein a determination process in said first
determination means (404) is carried out prior to a
determination process in said second determination
means (404).
Claim 11
Dependent Claim
49 words
The copying apparatus as claimed in claim
10, wherein the first method and the second method are
decided so that a time required for the determination
process in said first determination means (404) is shorter
than a time required for the determination process in
said second determination means (404).
Claim 12
Dependent Claim
30 words
The copying apparatus as claimed in claim
10, wherein a determination accuracy of said second
determination means (404) is higher than a determination
accuracy of said first determination means (404).
