Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of selecting a circulating mode, a non-circulating mode, and / or a manual feed mode, and a document transporting unit that serves as a document retainer in manual operation, a binding of copy sheets, and the like. The present invention relates to a copier equipped with a final processing unit that can select the final processing mode. [Background of the Invention] Generally, in a document feeder of a copying machine of this type, documents stacked on a document stacker are separated one by one and fed to a processing unit (on a platen glass), and synchronous exposure is performed in the processing unit. After that, it is circulated to the document stacker, and a copy mode is created in which a copy sheet is created for every page of the document once (RD
F) and the originals stacked on the original stacker are separated one by one and fed to the processing unit, and after being stopped at the processing unit, the exposure optical system is reciprocally moved by the number of making units to perform exposure, Non-circulation mode (ADF) that discharges documents to the output tray,
Manually feed the originals one by one from the paper tray and feed them to the processing section.
After leaving the processing unit stationary, the exposure optical system is moved back and forth by the number of making copies to perform exposure, and after the exposure process, there is a manual feed mode (SDF) for discharging to the discharge tray, and the document feeding unit holds the document. In many cases, manual operation is possible. Then, the document information obtained by the processing section is image-formed in the main body of the copying machine, and is transferred to a fed transfer sheet in a sheet container at a timing corresponding to the image-forming, and is fixed to be a copy sheet. And sent to the final processing section. The final processing section is provided with a lower tray having means for making a binding hole and a means for binding with a binding tool (staple), and an upper tray (offset tray) having no such means, and a final processing mode is selected. Sometimes the copy sheets are stored in the lower tray, otherwise they are stored in the upper tray. However, when the document transport section is set to the circulation mode, the copy sheets are prepared in the page order regardless of the number of copies to be prepared. However, if the number of copies is set to plural in the non-circulation mode, the manual feed mode or manually. As a result of overlapping the same page by the number of copies, if one of these non-circulation mode, manual feed mode or manual is selected and the final processing mode is selected, the copy sheets with the same page overlapped are placed in the lower stage of the final processing section. There was the inconvenience of entering the tray and performing final processing such as binding. In fact,
If such a binding method is not performed, and copy sheets of the same page are bound into one sheet, it will result in the trouble of re-binding the sheets in different page orders in order later. [Object of the Invention] In view of the above points, the present invention is such that when one of the non-circulation mode, the manual feed mode or the manual is selected, even if the final processing mode is selected, the copy sheets of the same page are combined into one. The purpose is to provide a copier that will not be bound. [Constitution of the Invention] The above object is to provide a document transport unit for transporting a document on a platen glass, a final processing unit for performing final processing such as binding of copy sheets one by one, a circulation mode for circulating the document, Circular selection means for selecting the original discharge mode in which the original is not circulated, final processing mode for performing the final processing, and final processing selection means for selecting a non-final processing mode for discharging the copy sheet without performing the final processing. And a copy number setting means for setting the number of copies, the copy number set by the copy number setting means when the document discharge mode is selected and the final processing mode is selected. The present invention is achieved by a copying machine characterized in that a copy number control means for making one copy is provided. The circulation selection means is, for example, a mode selection button on the operation panel of the main body of the copying machine, which can arbitrarily select either RDH (circulation mode) or ADF (non-circulation mode).
Similarly to the circulation selection means, the final processing selection means is a mode selection button on the operation panel of the main body of the copying machine capable of selecting whether or not to perform the final processing such as staples. is there.
