Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus having a mode for designating a document size.

[0002]

2. Description of the Related Art Conventionally, in this type of image forming apparatus,
For example, when manuscript frame erase, book frame erase, reduction layout, and the like are designated, all manuscript sizes are displayed on the display unit as candidates, and the manuscript size is designated from among them.

[0003]

However, recently, each company has become more and more international, and a variety of manuscripts are used for each domestic and foreign destination. However, when manuscript size candidates are all sizes. A large number of document size candidates are displayed on the display unit, and it takes a lot of time to find the document size to be used from the candidates.

The present invention has been made in view of the above conventional problems, and its purpose is to provide an operator (user) in the case of a mode for designating a document size.
By previously registering and storing the candidate document size to be used from among all the document size candidates of the apparatus, the candidate size unnecessary for setting the document size candidate is deleted from the registration beforehand. Accordingly, it is an object of the present invention to provide an image forming apparatus capable of shortening the time required to search for a desired document size candidate from among a large number of all document size candidates.

[0005]

Therefore, in the present invention, in the copy mode for designating the document size, the document size designating means for designating the document size from the document size candidate group and the operator designating the document size. Manuscript size candidate setting means for designating a plurality of manuscript size candidates that can be designated by means, storage means for storing a manuscript size candidate group selected by this manuscript size candidate setting means, and operation of the manuscript size designation means It is intended to achieve the above-mentioned object by configuring the document size candidates in the document size designating unit to be a group of candidates registered in the storage unit.

[0006]

With the above-described structure of the present invention, the operator can previously designate and store a document size group to be used from among all the document size candidates of the apparatus, so that the time required for designation of a desired document size can be reduced. Can be significantly shortened.
