When the EED signal rises, the DH 130 starts feeding the document and raises the DH_ACT signal that is being operated.
When the DH 130 completes the feeding of the document, the DH_ACT signal falls to indicate that a copy operation (document reading operation) is possible for the image forming apparatus main body.
Start the signal.

The main body of the image forming apparatus detects the fall of the DH_ACT signal and lowers the ORG_FEED signal to notify the DH 130 that the completion of document feeding from the DH 130 has been acknowledged. After the ORG_FEED signal falls, the image forming apparatus main body starts an original reading operation to read the original, and outputs a preview monitor C
The image forming result is displayed on the RT 131 or a copying operation is performed.

The above is the description of the operation for one document. Since FIG. 9 shows the operation for three sheets, the above operation is performed three times.

Next, when the operation of the three originals is completed, since there is no next original, the image forming apparatus main body raises the ORG_EJCT signal to the DH 130 to request the original to be discharged. Upon detecting the rise of this signal, the DH 130 lowers the COPY_REQ signal indicating that copying is possible, and
The _ACT signal is activated to start the discharge. When the DH 130 finishes discharging the document, it lowers the DH_ACT signal,
It notifies the image forming apparatus main body that the discharge has been completed.

The image forming apparatus main body detects the fall of this signal and falls the ORG_EJCT signal. This concludes the description of the communication specifications for the control of the DH 130 (document handler control) for three originals.

The image output of which the image has been edited is printed out collectively based on the editing and processing information stored in.

When the document handler 130 is of the recirculating type (the document returns to the original place), the document is automatically fed by pressing the copy start key, but the document handler 130 is not of the recirculating type (the document is of the original type). In this case, the user re-sets the original on the table of the document handler 130 and presses the copy start key.

In the above embodiment, the document A4 and the paper A
Although the preview operation has been described in the 4,4in1, reduced layout mode, it goes without saying that the preview operation is not necessarily limited to this mode. For example, original A4, paper A3,
