Abstract

PURPOSE:To interpose a white paper recording medium on each of recording media classified for each part on each bin so that the medium may protrude in case of discharging the recording media after image formation on each of the bins for each part and classify them by a sorting means and to simplify subsequent classification work. CONSTITUTION:In case of acquiring a desired number of copies by way of copying a plural number of scripts in series by using an automatic script feeding device, copy forms of each part are discharged on each pin for each part and classified by a sorting means. In this case, when a 'SHIORI' mode button provided on an operation panel is operated, on each of the copy forms P discharged and classified for each part on each bin, a white paper copy form P of the same size as the copy form P is supplied from a sheet supply means, and simultaneously, this white paper copy form P is discharged and placed in the Y direction which is different from a sheet discharge direction X of the copy form P discharged on each bin by a second sheet supply means and classification for each part is made clear.

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 sorting function for sorting a plurality of sets of recording media (hereinafter referred to as copy sheets) into respective sets in, for example, an electronic copying machine or a laser printer. Is.

[0002]

2. Description of the Related Art In an image forming apparatus of this type, for example, an electronic copying machine, a sheet feeding cassette set in a plurality of stages by selecting a requested copy sheet size on an operation panel when performing a copying operation. Paper is being fed from.

Further, conventionally, when a desired number of copies are obtained by copying a plurality of originals in series by using, for example, an automatic original feeding device, copy sheets are ejected and sorted into respective bins for each copy. A new sorter has been developed and put into practical use.

[0004]

However, in the sorter in such a conventional image forming apparatus, when the copy sheets sorted on the respective bins are taken out, all the copy sheets are collectively taken out. Therefore, there is a problem in that it is impossible to distinguish the copy sheets sorted from each other.

The present invention has been made under the above circumstances, and an object thereof is to make it possible to take out copy sheets sorted in respective bins separately for each set. An object is to provide an image forming apparatus.

[0006]

In order to solve the above-mentioned problems, the present invention comprises an image forming means for continuously forming images of a document on a plurality of recording media, and a recording medium. A first paper feeding means for feeding the recording medium to the image forming means in the first direction, and a recording medium of the same size as the recording medium accommodated in the first paper feeding means. A second paper feeding unit that feeds the recording medium to the image forming unit in a second orientation different from the first orientation, and a feed from the first paper feeding unit to the image forming unit. Storing means having a plurality of bins for sorting and storing the recording medium in the first direction on which the image of the document is formed, and the storing means of the storing means when the continuous image forming operation in the image forming means is completed. Remove the top bin in use. Is obtained by a provided to become a configuration and control means for controlling said second sheet feeding means to supply a recording medium of the second orientation for each bin.

Further, according to the present invention, an image forming means for continuously forming images of an original on a plurality of recording media and a recording medium of a first size are housed, and the first image forming means is provided. First feeding means for feeding a recording medium of a size of
A second paper feeding means for accommodating a recording medium of a second size larger than the first size and supplying the recording medium of the second size to the image forming means; A storage means having a plurality of bins for sorting and storing a first-size recording medium on which an image of a document is formed, which is supplied from a paper means to the image forming means, and a continuous means in the image forming means. When the image forming operation is completed, the second paper feeding unit is controlled so as to supply the recording medium of the second size to each bin other than the uppermost bin used in the storage unit. And a control means for controlling.

[0008]

That is, according to the present invention, by adopting the above-mentioned structure, the plurality of copies of the recording medium image-formed by the image forming means are discharged by the sorting means onto each bin for each copy. In addition to sorting, a blank recording medium of the same size as that of the recording medium is discharged on each recording medium except the uppermost recording medium that is discharged into each bin and sorted in each direction. Since the sheet is discharged or a blank recording medium having a size larger than that of the recording medium is discharged and placed, each blank recording medium protrudes and intervenes between the respective units, thereby Even if a plurality of recording media are taken out at once, it is possible to take out them separately for each part.

The optical system includes 7, 38, 39 and the like.

That is, an image of a document (not shown) placed on the document table 10 is scanned by the exposure device 30 and is exposed on the photosensitive drum 3 of the image forming means 2. The electrostatic latent image formed on the photosensitive drum 3 is developed by the developer supplied by the developing device 4 to form a developed image. To do.

On the other hand, on one side of the apparatus main body 1,
The first paper feed cassette 40 has a second paper feed tray at the inner bottom thereof.
Further, a third paper feed cassette 50, 60 is provided, and a manual paper feed section 70 is provided in the first paper feed cassette 40.

The paper feed cassettes 40, 50, 6
0 or copy paper P fed from the manual paper feed unit 70
Is a pickup roller 41, which constitutes the paper feeding means 80,
The copy sheets P are taken out one by one via the sheet feeding rollers 42, 52, 62 and the sheet feeding rollers 42, 52, 62.
Through the transfer device 5 that is guided to the photoconductor drum 3 so as to be conveyed to the photoconductor drum 3 so as to be fed, and the developed image developed by the developing device 4 is copied by the transfer device 5 onto the copy sheet P. It is designed to be transcribed on top.

The copy sheet P after the transfer by the transfer device 5 is peeled by the peeling device 6 by AC corona discharge, and is fixed by the fixing belt 1 via the conveying belt 13 which is a conveying means.

As shown in FIG. 1, a blank copy sheet of the same size as the copy sheet P is placed on each copy sheet P except the uppermost copy sheet P that is discharged and sorted into each bin 202 for each set. It is controlled so that P is fed from each of the paper feeding means and ejected, and the blank copy paper P is ejected onto each bin 202 by the second paper feeding means. The sheet is discharged and placed in a direction Y that is different from the sheet discharge direction X.

In the above embodiment, when the blank copy sheet P is ejected and placed on the uppermost copy sheet P which is ejected and sorted into each bin 202, the copy sheet P is placed. Blank copy paper P of the same size as
Although the paper is ejected in the direction Y different from the above, a blank copy paper P having a size larger than the copy paper P may be ejected and placed as shown in FIG. 6 as another embodiment.

[0022]

As is apparent from the above description, according to the present invention, a plurality of sets of recording media on which images are formed by the image forming means are ejected onto the respective bins by the sorting means. Paper is sorted and discharged, and a blank recording medium of the same size as that of the recording medium is discharged on each recording medium except the uppermost recording medium that is discharged and sorted for each set on each bin. Since the sheet is discharged in the direction, or a blank recording medium having a size larger than the recording medium is discharged and placed, each blank recording medium is interposed so as to protrude between the respective units. Therefore, even if all the recording media are collectively taken out as in the conventional case, they can be taken out separately for each unit.
