Abstract
Abstract A copying system has an automatic document feeder capable of feeding continuous original. This system has a device for inputting the number of sheets of the original to be copied, a counter for counting the number of copied sheets of the original, a comparator for comparing data outputted from the inputting device and the counter with each other, a body controller for controlling the copying operation of the copying system, and a feeder controller for outputting commands for feeding and discharging the sheets of the original to the automatic document feeder by the data from the comparator. The feeder controller outputs a copy processing signal to the body controller.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
222 words
A copy system having an automatic document feeder for feeding a continuous original including a plurality of sheets to said copy system, comprising: means for inputting at least one sheet number corresponding to at least one sheet of said original to be copied, said sheet numbers being assigned sequentially on a plurality of said sheets of the original, wherein said at least one sheet number may correspond to any of said plurality of sheets of said continuous original; means for counting the number amount of said sheets of said original which are fed by said automatic document feeder, based on output signals outputted from said automatic document feeder at every copy processing, said output signals for feeding and discharging said original; means for comparing at every copy processing said sheet numbers inputted by said inputting means with said counted number amount of sheets of said counting means; copying machine body control means for controlling the copying operation of the copying system; and feeding control means for outputting commands to said automatic document feeder so as to feed and discharge the originals until said counted number amount of the sheets of the original is in conformity with said inputted at least one sheet number of the original to be copies, and for outputting a copy processing signal to said copying machine control means.
Claim 2
Dependent Claim
222 words
A copy system having an automatic document feeder for feeding a continuous original including a plurality of sheets to said copy system, comprising: means for inputting at least one sheet number corresponding to at least one sheet of said original to be copied, said sheet numbers being assigned sequentially on a plurality of said sheets of the original, wherein said at least one sheet number may correspond to any of said plurality of sheets of said continuous original; means for counting the number amount of said sheets of said original which are fed by said automatic document feeder, based on output signals outputted from said automatic document feeder at every copy processing, said output signals for feeding and discharging said original; means for comparing at every copy processing said sheet numbers inputted by said inputting means with said counted number amount of sheets of said counting means; copying machine body control means for controlling the copying operation of the copying system; and feeding control means for outputting commands to said automatic document feeder so as to feed and discharge the originals until said counted number amount of the sheets of the original is in conformity with said inputted at least one sheet number of the original to be copies, and for outputting a copy processing signal to said copying machine control means.
Claim 3
Dependent Claim
17 words
A copying system as claimed in claim 1, wherein said original comprises a continuous computer form paper.
Claim 4
Dependent Claim
37 words
A copying system as claimed in claim 2, wherein a necessary portion of said continuous computer form paper is copied by commanding the sheet numbers without separating this necessary portion from the other portions of the paper.
Claim 5
Dependent Claim
51 words
A copying system as claimed in claim 1, wherein the command for feeding the sheets of the original is transmitted to the automatic document feeder when the counted number amount of the sheets of the original is not in conformity with the inputted sheet numbers of the original to be copied.
Claim 6
Dependent Claim
35 words
A copying system as claimed in claim 1, wherein the command for discharging the sheets of the original is transmitted to the automatic document feeder when the copying processing by the copying machine is completed.
Claim 7
Dependent Claim
34 words
A copying system as claimed in claim 1, wherein the automatic document feeder feeds said original by one sheet number amount thereof on the basis of the paper discharging command from the copying machine.
Claim 8
Dependent Claim
50 words
A copying system as claimed in claim 1, wherein the copying operation is completed and the operation of the automatic document feeder is also completed when the counted number amount of the sheets of the original is in conformity with the inputted sheet numbers of the original to be copied.
