Next, a specific example will be shown in which the cover mode and APS mode are selected at the same time. Make multiple copies from multiple originals,
Indicates a mode in which the final paper is fed from a specific cassette as the cover of each section. In this embodiment, the cover paper is stored in the upper cassette 15.
It is stored in 1.

FIG. 4 shows the main flowchart of this operation.

First, wait for the copy key 605 to be pressed (step 4-1), and when the copy key 605 is pressed, the RDF3
00, and waits for the document to be fed onto the platen glass 101 (step 4-2).

After feeding the original, APS processing is performed to select an appropriate size from the original size information from the RDF 300 and the copying magnification (step 4-3) (The APS routine will be explained in the next section). Note that the document size is determined by detecting the passage time of the document by a sensor (not shown) provided in the middle of the conveyance path from the stacking tray 301 to the platen glass 101. Then, it is determined whether it is the final original (step 4-4), and if it is not the final original, the copying operation for the number of copies is performed by feeding the paper from the cassette 153 or deck 201 selected in step 4-3. If it is the final document, upper cassette 1, which is a specific cassette for cover mode.
51, switch (step 4-5), copy the cover sheet fed from the cassette 151 for the number of copies (step 4-6), and if it is determined in step 4-4 that it is not the final document, If it is the final document, the process ends (step 4-7), but if not the final document, the process returns to step 4-2 and repeats the above-described series of controls.

Note that the recycle lever 309 determines whether or not it is the final document.

Next, APS processing will be explained. FIG. 5 shows a flowchart of APS processing. First, an appropriate size is selected from the original size and copy magnification from the RDF 300 (step 5-1). For example, when the magnification of an A3 size document is 70%, an A4 size cassette is selected as a candidate. and,
Step 5-2) to determine whether there is a cassette or deck with recording paper of the appropriate size selected as a candidate.
If it does not exist, the correct size cassette missing processing routine (
If the cassette or deck exists, it is determined whether the cassette or deck is a specific cassette for cover mode (Step 5-3), and if it is a specific cassette, the selection of the specific cassette is prohibited and the proper size cassette is set. If the cassette is not a specific cassette, the cassette is selected and the process returns to the main routine (step 5-4).

The process of not having an appropriate size cassette displays a message on the operation panel stating that there is no appropriate size cassette (Step 5-5), and waits for it to be replaced with an appropriate size cassette (Step 5-6). Return to main routine.

Next, an example will be described in which the copying operation is prohibited when the recording material size of the cassette selected by the APS function and the cover sheet size are different.

FIG. 6 shows a main flowchart of the operation of this embodiment. First, the original is set (S6-1), the APS mode is selected (S6-2), the cover mode is selected (S6-3), and the copy key 605 is waited for to be pressed (S6-4).
. When the copy key 605 is turned on, the RDF 300 feeds the document (S6-5), detects the size of the document while conveying it, and selects a cassette based on the size (S6-6). Then, compare the selected cassette size and the cover cassette size (S6-7), and if they are different, stop copying at that point (S6-8), and display the display 701 of the operation unit, for example, "Hyoshino Size". A message such as "Gachigai Masu" is output (S6-9). In this way, by comparing the first page of the original with the cover size of the final original and issuing an alarm, it is possible to notify the operator of any erroneous operations at an early stage.

Note that if the sizes are the same in 56-7, the paper is fed from the selected cassette until the final document arrives (56-10), the copying operation for the number of copies is performed (S6-12), and the document feeding is repeated (S6). -14). If it is the final document in S6-10, select the cover cassette for the first time (56-11), perform the copying operation for that number of copies (S6-12), complete the operation, and then start the series of processes in the cover copy mode. Terminate it.

The above is an example of operation when cover mode and APS mode are selected at the same time. In this embodiment, the last paper for each number of original sheets is fed from a specific cassette, but a specific paper is inserted after each arbitrary number of sheets. The same can be said for modes such as copying or copying on specific paper.

〔effect〕

As explained above, according to the present invention, in the cover mode, the AP
Even when S is performed, the specific cassette is excluded from the APS target, so the problem of a specific cassette being selected against the operator's will can be eliminated.

Further, according to the present invention, when APS is performed in the cover mode, if the recording material size of the selected storage means differs from the specific paper size, the image forming operation is controlled, so that the image forming operation is controlled according to the operator's intention. On the other hand, it is possible to prevent inappropriate copy sets from being created.
