When the user changes the setting this time (Yes in S12), the process returns to step S5. When the setting is not changed (No in S12), the copy key 5 is pressed to execute the copy based on the document D as it is (S13), and the process is completed.

By such an operation, even when the direction of the document D and the direction of the sheet P are the same and the magnifications do not match, only one copy is first made and a display prompting the user to confirm is displayed. Therefore, even if the number of copies is set to a large number, it is possible to prevent a large amount of miscopy.

Further, in the above-mentioned judgments in steps S7 and S8, it is judged that the size of the user's original document D is A4 this time and the direction changing condition X is satisfied, and the magnification matches the magnification reference value 141% at this time. If it is determined that this is the case, the process moves to step S14, and the display section 8 displays "Please change the orientation of the document" (S14). This state is shown in FIG.

At this time, if the user changes the orientation of the document D (Yes in S15), the process returns to step S5, and
Unless the orientation of the document D is changed (No at S15), Step S1
3, the copy key 5 is pressed to execute the remaining number of copies based on the document D (S13),
It ends.

FIG. 11 shows the case where the combination of the original document D and the paper sheet P meets the direction changing condition X and the magnification is 1 ×, and FIG. 12 shows the combination of the original document D and the paper sheet P changing the direction condition X. And the magnification is a magnification reference value of 71%.
