2. Description of the Related Art As is well known, an electrostatic electrophotographic copying machine comprises unit processes of charging, exposing, developing, transferring and fixing. In the unit process configured as above, copying is performed by the following process. First, an electrostatic latent image is created by exposing the surface of the photoconductor, which is given a uniform charge by a charger charger, to the reflected light of the original image through an optical system. Electrodeposit and develop to form a toner image on the photoconductor, then transfer the toner image onto the recording paper by static electricity of the opposite polarity to the toner image applied to the transfer body, and remove the transferred toner on the recording paper. The image is fixed on the recording paper by heating and pressing to fix the image according to the original image.

To expose the image of the original on the photosensitive member, there are a method of fixing the original and optically scanning, and a method of moving the original and optically scanning. The former is a method in which an original placed on an original placing table made of transparent hard glass is pressed by an original cover and the reflected light obtained by irradiating light from the lower surface of the original is scanned while moving the exposure optical system ( Hereinafter referred to as OC mode)
In the latter, for example, a circulation type document feeder (hereinafter referred to as RDH) is mounted on the upper part of the exposure optical system, and the exposure optical system is fixed while moving the manuscript loaded on the RDH original table. This is a scanning method (hereinafter referred to as RHD mode). OC mode and RDH are used for recent copying machines of intermediate level and above.
Generally, the modes and are provided, and both can be selected and copied.

The OC mode is used when copying from one or a small number of originals or an original having a size that cannot be inserted into the RDH, and the RDH mode is used when automatically copying a large number of originals. Therefore, the copying time in the RDH mode is usually long, and it is required to interrupt the copying in the RDH mode and perform copying in other modes depending on the circumstances. In the conventional copying machine, the copying time in the RDH mode is required. The interrupt mode for interrupting during copying is set. The following functions were available when interrupted. Stop the copying process that has been completed. At this time, the originals are returned to the original placing table of the RDH in page order. OC mode or RDH selected after document return is completed
The mode can be interrupted. The originals being conveyed are returned to the original table. In this case, the document stops halfway through the page, and only the OC mode can be interrupted.

[0005]

In the conventional copying machine, in the above-mentioned case in which an interrupt is applied during copying in the RDH mode, in the case of, the OC mode or the RDH mode can be interrupted, but R
Since the DH stops after completing one copy, it takes time to interrupt the OC mode. In this case, since the original document to be copied is stopped in the middle of the page, interruption to the OC mode does not take time, but interruption to the RDH mode could not be made. Even if an attempt is made to forcibly interrupt the RDH mode, it is necessary to pull out the document that is stopped midway, and at this time, there is a problem that some of the mechanisms inside the RDH are damaged.

[0006]

In order to achieve the above-mentioned object, the present invention provides a copying machine having an optical system moving mode for copying from a fixed original image and an original moving mode for copying from a moving original, wherein the original moving mode is set. A manuscript movement mode interrupt setting means for making an interruption copy in a manuscript movement mode, an optical system movement mode interruption setting means for making an interruption copy in a movement mode, and each of the setting means for which interruption is set. Having control means for controlling,
Further, (2) the manuscript movement mode interruption key for setting an interruption to the manuscript movement mode and the optical system movement mode interruption key for setting an interruption to the optical system movement mode are arranged on the operation panel in a selectable manner. It is characterized by.

[0007]

When the interrupt selected during copying in the RDH mode is interrupted in the OC mode, only the originals in the RDH are returned to the original placing table in the RDH. When interrupting the RDH mode Stop after completing one copy. As described above, it is possible to select either the OC mode or the RDH mode according to the purpose, the interruption to the OC mode takes a short time, and the operation to interrupt the RDH mode becomes simple.

Step 7 : When it is detected that the interrupt copying is completed, the interrupt is released, and the interrupted original is copied in the RDH mode (step 2) based on the value stored in the microcomputer 204.

[0032] step8: RDH mode (step2) in the (interrupt to the OC) during the pause 2 to the copying is pressed. step9 : The copy being made in the RDH mode is interrupted. step10 : The original being conveyed is returned to the original placing section 1. step 11 : Detecting that the original document being conveyed has returned to the original document placement section. step12 : Perform interrupt copying to OC mode. Step 13 : When it is judged that the copying in the OC mode is completed, the processing is returned to the step 2, and the copying in the RDH mode, which has been suspended, is performed based on the value stored in the microcomputer. step14 : It is judged that copying in the RDH mode is completed. step15 : When copying is completed, the flow stops.

[0033]

When the interrupt copy is performed during copying in the RDH mode, it is possible to select whether the interrupt is the OC mode or the RDH mode by the selection key. When interrupting the OC mode, the RDH original is conveyed. When only the original document is returned to the document table and the RDH mode is interrupted, one copy is completed and then stopped. Therefore, both the OC mode and the RDH mode can be interrupted depending on the purpose of the interrupt.
As a result, when the OC mode is interrupted, it can be performed in a short time, and when the RDH mode is interrupted, the operation is simple. It became possible to copy an interrupt to any of the modes.
