DESCRIPTION:
BRIEF SUMMARY
TECHNOLOGICAL FIELD
The present invention relates to an image recording apparatus such as a plain paper copier, a laser printer, or a facsimile, and more particularly to an image recording apparatus having a sort function and a stable function which sorts recording paper with image data recorded thereon with a sorter and binds bundles of sorted recording paper into a book with a stapler.
BACKGROUND TECHNOLOGY
In an office environment are documents each having a different size. The documents are generally bound into files or books and are stored on desks or in cabinets.
In private companies, paper having a size of A4 or A3 is often used, but in government and public offices size B paper is relatively often used partially because use of size B paper is required by law or other regulations such as ministry ordinances. As a result, size A paper and size B paper coexist there. This is a cause for generation of a big problem in storage and management of documents.
Recently because of the circumstances as described above, a plan for unification of document sizes in government and public offices has been undergoing. Accordingly, sizes of documents to be prepared anew in the future can be unified according to a new rule.
However, documents already prepared have been stored as original documents each having a size B (for instance, a size of B5), if a copying machine is used to make a copy of an original document having a size of B5, excluding a case where it is required to enlarge or reduce a size of the document, generally copying is executed on recording paper having a size of B5.
On the other hand, there is a copying machine having a function to detect a size of a document, automatically select recording paper having a size suited to the document from a paper feed cassette and send out the paper, but it is difficult to insure copying on recording paper having a unified size (for instance, size A4) in the copying machine as described above. Even in a copying machine not having the function as described above, if various types of recording paper having a different size respectively are set therein, the possibility for a user to select recording paper having the same size as that of an original document is very high, so that it is difficult to execute copying on recording paper having a unified size. For this reason, in order to insure unification of sizes of recording paper into a unified one in an office, it is necessary to use a copying machine which allows only recording paper having a specified size to be set therein.
However, if this type of copying machine is used, there occurs no problem when a document having a size smaller than A4 is copied, but a document larger than size A4 can not be copied with the same size, which is inconvenient. For this reason, when it is required to copy a document having a size larger than A4 with the same size, it is necessary to record a sheet of document on two sheets of recording paper making use of a cross-page continuous copying technique.
When using the cross-page continuous copying technique, if it is tried to copy, for instance, a document 4901 having a size of A3 larger than A4 onto two sheets of recording paper 4902, 4903 each having a size of A4 as shown in FIGS. 27 (a), (b), an image of the document 4901 is simply divided ibto two portions and recorded on each sheet of recording paper as shown in FIG. 27 (b).
However, and with reference to FIG. 28, with a copying machine in which the conventional type of cross-page continuous copying technique is simply applied, when dividing and recording a size A3 document to two sheets of size A4 recording paper, there occurs no specific problem, but when a size B4 document 4002 is placed on a document mount 4001 for copying it onto recording paper having a size of A4, reproducibility of the document image is disadvantageously degraded.
Concretely the document 4002 is divided at the center thereof into two portions 4002a, 4002b each having a size of B5. As shown in FIG. 28 (b), these images are positioned substantially at cent
