Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
275 words
A copying apparatus, comprising: image forming means for forming a duplicate sheet of a document placed in an exposure position; a circulating automatic document feeding unit which has a document container for storing one set of documents stacked in order, wherein the documents are transported sheet by sheet from the document container to the exposure position and again stored in the container after the exposure; means for storing duplicated sheets, said storing means including means for stapling one set of the duplicated sheets stored in the storing means; means for entering a number of copies to be prepared per one set of documents; first control means for operating continuously both the image forming means and the circulating automatic document feeding unit until the image forming operation for a specific number of sets of copies has been completed, the specific number being the number entered by the number entering means; means for selecting either a stapling mode or a nonstapling mode; second control means for controlling the storing means in the stapling mode and in the non-stapling mode, wherein when in the stapling mode the storing means stores the duplicated sheets and the stapling means operates every time after a completion of the storing operation for stapling each set of duplicating sheets, and when in the nonstapling mode the storing means stores the duplicated sheets without operating the stapling means; and third control means, responsive to the selection of the non-stapling mode during the storing operation in the stapling mode, for controlling said storing means in the non-stapling mode after the completion of the storing and stapling operation to the set of copies currently being stored.

A copying apparatus, comprising: image forming means for forming a duplicate sheet of a document placed in an exposure position; a circulating automatic document feeding unit which has a document container for storing one set of documents stacked in order, wherein the documents are transported sheet by sheet from the document container to the exposure position and again stored in the container after the exposure; means for storing duplicated sheets, said storing means including means for stapling one set of the duplicated sheets stored in the storing means; means for entering a number of copies to be prepared per one set of documents; first control means for operating continuously both the image forming means and the circulating automatic document feeding unit until the image forming operation for a specific number of sets of copies has been completed, the specific number being the number entered by the number entering means; means for selecting either a stapling mode or a nonstapling mode; second control means for controlling the storing means in the stapling mode and in the non-stapling mode, wherein when in the stapling mode the storing means stores the duplicated sheets and the stapling means operates every time after a completion of the storing operation for stapling each set of duplicating sheets, and when in the nonstapling mode the storing means stores the duplicated sheets without operating the stapling means; and third control means, responsive to the selection of the non-stapling mode during the storing operation in the stapling mode, for controlling said storing means in the non-stapling mode after the completion of the storing and stapling operation to the set of copies currently being stored.
Claim 3
Dependent Claim
51 words
A copying apparatus as claimed in claim 1, wherein the storing means comprises: a tray for storing copying papers; means for transporting copying paper to the tray; means for pressing stored copying papers on the tray; and means for operating the pressing means in synchronization with a copying paper transporting operation.
Claim 4
Dependent Claim
81 words
A copying apparatus as claimed in claim 1, wherein the storing means comprises: first means for storing copying papers; second means for storing copying papers means for diverting selectively transporting copying paper either to the first storing means or the second storing means; and means for controlling the diverting means in order to transport copying paper to the first storing means if the stapling mode has been selected, and to the second storing means if the non-stapling mode has been selected.
Claim 5
Dependent Claim
39 words
A copying apparatus as claimed in claim 1, further comprising means for indicating a number of sets of copies to be prepared, per one set of copies, and where the number has been entered by the numeral entering means.
Claim 6
Dependent Claim
270 words
A copying apparatus, comprising: image forming means for forming a duplicate sheet of a document placed in an exposure position; a circulating automatic document feeding unit which has a document container for storing one set of documents stacked in order, wherein the documents are transported sheet by sheet from the document container to the exposure position and again stored in the container after the exposure; means for storing duplicated sheets, said storing means including means for stapling one set of the duplicated sheets stored in the storing means; means for entering a number of copies to be prepared per one set of documents; first control means for operating continuously both the image forming means and the circulating automatic document feeding unit until the image forming operation for a specific number of sets of copies has been completed, the specific number being the number entered by the number entering means; means for selecting either a stapling mode or a nonstapling mode; second control means for controlling the storing means in the stapling mode and in the non-stapling mode, wherein when in the stapling mode the storing means stores the duplicated sheets and the stapling means operates every time after a completion of the storing operation for stapling each set of duplicated sheets, and when in the nonstapling mode the storing means stores the duplicated sheets without operating the stapling means; and third control means which allows the designation of the non-stapling mode during the image forming operation in the stapling mode before the specific number, which has been instructed by the number entering means, of sets of copies have been completed.
