2. Description of the Related Art As is well known, an electrophotographic copying machine is constituted by unit processes of charging, exposure, development, transfer and fixing. In the unit process configured as described above, copying is performed by the following process. First, an electrostatic latent image is formed by exposing the surface of a photoreceptor, to which a uniform charge has been given by a charger, to light reflected from a document image via an optical system, and a toner (developer) is applied to the electrostatic latent image. A toner image is formed on the photoreceptor by developing the toner image on the photosensitive member, and then the toner image is transferred onto the recording paper by static electricity having a polarity opposite to that of the toner image applied to the transfer member. The image is fixed by heating and pressing to fix an image corresponding to the original image on the recording paper.

To expose a document image on a photoreceptor, there are a method in which the document is fixed and optical scanning is performed, and a method in which the document is moved and optical scanning is performed. In the former method, a document placed on a document placing table made of transparent hard glass is pressed by a document cover, and reflected light obtained by irradiating light from the lower surface of the document is scanned while moving through an exposure optical system ( Hereinafter, it is called an OC mode.)
In the latter, for example, a circulating 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 document loaded on the document mounting table of the RDH. This is a scanning method (hereinafter, referred to as an RHD mode). OC mode and RDH
Modes are generally provided so that both can be selected and copied.

The OC mode is used when copying from one or a small number of documents or a document having a size that cannot be inserted into the RDH, and the RDH mode is used when copying a large number of documents automatically. Therefore, the copying time in the RDH mode is usually long, and depending on circumstances, it is required to interrupt the copying in the RDH mode and perform the copying in another mode. An interrupt mode for interrupting during copying is set. The functions when interrupted were as follows. Since one copy in progress is completed, it is stopped. At this time, the document returns to the document placing table of the RDH in page order. OC mode or RDH selected after document return is completed
The mode can be interrupted. The original being transported is returned to the original mounting table. In this case, the document stops in the middle of the page, and only interruption to the OC mode is possible.

[0005]

In the above-described conventional copying machine in which an interruption was made during copying in the RDH mode, in the following case, interruption to the OC mode or the RDH mode is possible,
Since the DH stops after completing one copy, it takes time to interrupt the OC mode. In the case of, the original to be copied stops halfway through the page, so it does not take much time to interrupt the OC mode, but the RDH mode could not be interrupted. Even if an attempt is made to interrupt the RDH mode by force, it is necessary to pull out the stopped document in the middle, and at this time, there is a problem that some mechanisms in the RDH are damaged.

[0006]

According to the present invention, there is provided a copying machine having (1) an optical system moving mode for copying from a fixed document and a document moving mode for copying from a moving document. available settings by moving mode during the copying, the original movement mode interrupt setting means for interrupt copying the document moving mode, an optical system moving mode interrupt setting means for interrupt copying the optical system moving mode, the moving original mode

After copying the original on the road,
And (2) a document movement mode interruption key for setting an interruption to the document movement mode, and an optical system movement mode interrupt for setting an interruption to the optical system movement mode. Keys are provided on the operation panel so as to be selectable.

[0007]

When interrupting an interrupt selected during copying in the RDH mode to the OC mode, only the RDH original is returned to the RDH original mounting table while the original being transported is interrupted. When interrupting to RDH mode: Stop after completing one copy. As described above, any one of the OC mode and the RDH mode can be selected according to the purpose, so that a short time is required to interrupt the OC mode, and the operation for interrupting the RDH mode is also simplified.

Step 13 : When it is determined that the copying in the OC mode is completed, the process returns to step 2, where the interrupted copying in the RDH mode is performed based on the stored value of the microcomputer. step 14 : It is determined that the copying in the RDH mode has been completed. step15 : When copying is completed, the flow stops.

[0033]

According to the present invention, when performing interruption copying during copying in the RDH mode, it is possible to select whether the interruption is in the OC mode or the RDH mode by using the selection key. When interrupting the OC mode, the RDH original is conveyed. When only the middle document is returned to the document table and interrupted to the RDH mode, the copying operation is stopped after completion of one copy, so that any of the OC mode and the RDH mode can be interrupted depending on the purpose of the interrupt.
As a result, when interrupting to the OC mode,
Copying can be performed immediately, and copying in OC mode
Can be done in a short time. In addition, when interrupting to the RDH mode, the operation is simplified, and the interrupt copying to the one of the two modes can now be performed by selection, although the interruption to the OC mode can only be performed conventionally.
