Claim 3

A copying apparatus as claimed in claim 1, wherein said discrimination means includes sheet-size memorizing means for memorizing said size detected by said size detecting means and a discrimination of said partitioning sheet by said discrimination means is effected on the basis of a comparison between said size, memorized in said sheet-size memorizing means of the original document and a size, detected by said size detecting means, of an original document subsequent to said original document.

Claim 4

Claim 6

A copying apparatus as claimed in claim 3, wherein said discrimination means includes sheet-size memorizing means for memorizing said size detected by said size detecting means and a discrimination of said partitioning sheet by said discrimination means is effected on the basis of a comparison between said size, memorized in said sheet-size memorizing means of the original document and a size, detected by said size detecting means, of an original document subsequent to said original document.

Claim 7

In a copying apparatus having an automatic document feeder which feeds original documents, taking the form of a plurality of sets of originals, placed on an original document-placing tray arranged therein to an exposure position sheet by sheet and discharges said original document placed on said exposure position sequentially after exposing, said apparatus comprising: size detecting means for detecting a size of said original document fed from said original document-placing tray; selecting means for selecting a specific operation mode; discrimination means for discriminating a boundary between said sets of originals during said specific operation mode when a partitioning sheet whose size is different from that of said original document is detected by said size detecting means while said each original document is fed, said partitioning sheet being inserted between said sets of originals; and control means for controlling said automatic document feeder so as to discharge said partitioning sheet from said exposure position without carrying out the exposing operation in the case where said partitioning sheet is detecting by said size detecting means when said specific operation mode is selected.

Claim 8

In a copying apparatus having an automatic document feeder which feeds original documents, taking the form of a plurality of sets of originals, placed on an original document-placing tray arranged therein to an exposure position sheet by sheet and discharges said original document placed on said exposure position sequentially after exposing, said apparatus comprising: size detecting means for detecting a size of said original document fed from said original document-placing tray; selecting means for selecting a specific operation mode; discrimination means for discriminating a boundary between said sets of originals during said specific operation mode when a partitioning sheet whose size is different from that of said original document is detected by said size detecting means while said each original document is fed, said partitioning sheet being inserted between said sets of originals; and control means for controlling said automatic document feeder so as to discharge said partitioning sheet from said exposure position without carrying out the exposing operation in the case where said partitioning sheet is detecting by said size detecting means when said specific operation mode is selected.

Claim 9

A copying apparatus as claimed in claim 5, wherein said discrimination means includes sheet-size memorizing means for memorizing said size detected by said size detecting means and a discrimination of said partitioning sheet by said discrimination means is effected on the basis of a comparison between said size, memorized in said sheet-size memorizing means of the original document and a size, detected by said size detecting means, of an original document subsequent to said original document.

Claim 10

In a copying apparatus having an automatic document feeder which feeds original documents, taking the form of a plurality of sets of originals, placed on an original document-placing tray arranged therein to an exposure position sheet by sheet and discharges said original document placed on said exposure position sequentially after exposing, said apparatus comprising: order means for ordering a start of a copying operation; size detecting means for detecting a size of said original document fed from said original document-placing tray; selecting means for selecting a specific operation mode; discrimination means for discriminating a boundary between said sets of originals during said specific operation mode when a partitioning sheet whose size is different from that of said original document is detected by said size detecting means while said original document is fed, said partitioning sheet being inserted between said sets of originals; and control means for controlling said copying apparatus so as to carry out said copying operation for a first original document which is fed directly after starting said copying operation ordered by said order means.

Claim 11

In a copying apparatus having an automatic document feeder which feeds original documents, taking the form of a plurality of sets of originals, placed on an original document-placing tray arranged therein to an exposure position sheet by sheet and discharges said original document placed on said exposure position sequentially after exposing, said apparatus comprising: order means for ordering a start of a copying operation; size detecting means for detecting a size of said original document fed from said original document-placing tray; selecting means for selecting a specific operation mode; discrimination means for discriminating a boundary between said sets of originals during said specific operation mode when a partitioning sheet whose size is different from that of said original document is detected by said size detecting means while said original document is fed, said partitioning sheet being inserted between said sets of originals; and control means for controlling said copying apparatus so as to carry out said copying operation for a first original document which is fed directly after starting said copying operation ordered by said order means.

Claim 12

A copying apparatus as claimed in claim 7, wherein said discrimination means includes sheet-size memorizing means for memorizing said size detected by said size detecting means and a discrimination of said partitioning sheet by said discrimination means is effected on the basis of a comparison between said size, memorized in said sheet-size memorizing means, of the original document and a size, detected by said size detecting means, of an original document subsequent to said original document.

Claim 13

A copying apparatus comprising: automatic original document feeding means, provided with an original document-placing tray, for feeding original documents placed on said original document-placing tray to an exposure position sheet by sheet; copying means for copying an image of said original document placed on said exposure position onto a copy paper sheet; discrimination means for discriminating a boundary between sets of originals placed on said tray, each of the sets of originals including one or more original documents; input means for inputting data of a copying condition to each of said sets of originals; memory means for memorizing the data inputted by said input means; interruption means for interrupting a copying operation in the case where there is no set of originals corresponding to said copying condition memorized by said memory means in said tray; and setting means for reading the data of said copying condition memorized by said memory means and setting said copying condition when said set of originals corresponding to said copying condition memorized by said memory means is re-placed on said tray after said interruption, effected by said interruption means, of the copying operation.

Claim 14
