Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading apparatus such as a scanner or a network scanner, an image forming apparatus such as a copying machine, a facsimile, a printer, and more particularly, a plurality of originals on one transfer sheet. The present invention relates to an image reading apparatus having a mode of copying on the same surface of the same and an image forming apparatus.

[0002]

2. Description of the Related Art Nin1 mode (aggregate mode) for copying a plurality of originals (for example, four originals) on the same side of one transfer paper can reduce the amount of transfer paper and the amount of toner used. This is a very effective function because it saves resources and reduces the amount of documents to be saved. For example, when making a copy in the 4 in 1 mode, unlike the usual case of making one copy from one copy, the finished copy may not be as the user desires depending on the method of setting the original. This is because the original feeding method and the mechanism of the function are complicated, and in order for the user to get the desired copy, it is necessary to understand the mechanism of this mode or try it many times. You will not be able to effectively use the special features. Further, specifically explaining based on FIG. 6, FIG.
6A, the image data (output material) obtained by feeding a conventional 4-in-1 original in the direction of the punch holes is as shown in FIG. However, a user who has empirically understood that if the punch holes and the staple traces are directed in the paper feeding direction (FIG. 6A), a document jam (paper jam) will occur due to the influence of that portion. Is often passed in the paper feeding direction as shown in FIG. Here, if it is not the Nin1 mode, it does not matter in the above case.
In the mode, the image data (output material) as shown in FIG. 6B is created.

In the invention described in Japanese Patent Laid-Open No. 10-3234, four originals are copied on the same side of one transfer sheet N.
In the in1 mode copying, it displays how the set originals are arranged and how the originals should be set to have a certain arrangement, and obtains a copy of the arrangement desired by the user at one time. There are things that enable you to do that.

[0004]

However, with the above-mentioned conventional technique, in order for the user to obtain the desired copy, the user must understand the mechanism of this mode or try it again and again. Then, the special functions cannot be used effectively. Further, in the invention described in Japanese Patent Application Laid-Open No. 10-3234, since the user has to make corrections while observing the display state instead of being fully automatic, it is still difficult for the user to make a desired copy. Further, an image forming apparatus having a small display unit may not be able to display everything on the display unit and may not be effectively used.
Therefore, it is an object of the present invention to allow a user to perform Nin1 (combined copying) without adjusting a document.
A method for solving those problems will be described later.
