Abstract

A combined system of an image processing machine (e.g., a copying machine) and a sheet handling machine. They are placed with an image reading part (e.g., a glass plate of the copying machine) therebetween. In the combined system, one-sided or two-sided original sheets and processed sheets are orderly stacked on respective final tray after they are finished processing if the original sheets are stacked orderly in the initial tray, i.e., the original sheets are laid on the final tray with the order of the page numbers maintained from the order at the initial tray, and the processed sheets are also stacked on the finish tray with the same order. In a simple mode: the original sheet is placed on the image reading part, processed (copied), reversed and ejected to a first final tray, while the process sheet (copy sheet) is processed and ejected onto the finish tray without reversing. In a reverse mode: an original sheet is first placed on the image reading part, first processed, recycled (reversed), second processed and ejected to a second final tray without reversing, while the process sheet is first processed, recycled (reversed), second processed, reversed and ejected to the finish tray.

Dependent claims

A system of an image processing machine and an original-sheet handling machine placed adjacent with an image reading part therebetween, the system comprising:

an initial tray provided in the original-sheet handling machine for laying a plurality of original sheets;
a placing mechanism provided in the original-sheet handling machine for taking an uppermost one of a plurality of original sheets in the initial tray and placing an original sheet on the image reading part by conveying it from one end of the image reading part;
a first recycling mechanism provided at the opposite side of the image reading part with respect to the initial tray in the original-sheet handling machine for removing an original sheet from the image reading part, reversing an original sheet and replacing an original sheet on the image reading part by conveying it from the opposite side of the image reading part, the first recycling mechanism including a large reversing roller by which an original sheet removed from the image reading part is reversed and replaced on the image reading part;
a first ejecting mechanism provided in the original-sheet handling machine for ejecting an original sheet on the image reading part either with reversing to a first final tray or without reversing to a second final tray;
a processing section provided in the image processing machine for processing a surface of a process sheet according to a surface of the original sheet placed on the image reading part;
a second recycling mechanism provided in the image processing machine for transporting a process sheet processed at the processing section again to the processing section with a processed surface upside down;
a second ejecting mechanism provided in the image processing machine for ejecting a process sheet processed at the processing section onto a finish tray;
a reversing mechanism provided in the image processing machine for reversing a process sheet upside down before a process sheet is ejected by the second ejecting mechanism;
and
a controller for controlling the movement of an original sheet in synchronism with the movement of a process sheet.
