Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine provided with a storing means for storing a recording medium according to size and a manual sheet feeding means.

[0002]

2. Description of the Related Art In this type of apparatus, various sheet feeding modes are settable, and a recording medium is fed to an image forming section based on the sheet feeding mode set on an operating section. Thus, various original images such as single-sided copy, double-sided copy, double-sided copy, single-sided multiplex, and double-sided multiplex can be copied onto a recording medium.

Further, in this type of apparatus, a manual sheet feeding port for the operator to manually feed the recording medium and a recording medium set in the manual sheet feeding port are detected, and the manual sheet is fed. In some cases, a feeding roller or the like for feeding to a predetermined position of the main body is provided. In addition, in this type of device,
In some cases, the paper size to be manually fed is not limited to the standard size, so the copying process is performed assuming that the paper size can be fed at maximum.

As described above, since there is a fear that an irregular size is also fed during manual feeding, when automatic paper selection is performed,
Since the paper size of the manual paper feed unit is indefinite, the manual paper that is set in the manual paper feed port as an automatic paper selection candidate is not automatically fed.

Further, even in the case of double-sided copying or multiplex copying, an irregular size may also be fed during manual feeding, so paper feeding from the manual feeding port is prohibited during double-sided copying or multiplex copying. Was there.

[0006]

Therefore, even if the size of the paper to be manually fed at the time of double-sided copying or multiplex copying is a fixed size, double-sided copying or multiplex copying cannot be performed without using a paper feed cassette or the like. There was a problem.

Further, there is a problem in that, when the automatic paper is selected, the manual paper feed port cannot be selected as a paper feed destination candidate although the paper size to be manually fed is a standard size.

Further, in automatic paper selection, when the paper size accommodated for feeding does not match the original size, for example, the original size is B5R, the paper size is B5 portrait and A4 size port. In the case of the rate, in this state, automatic paper selection cannot be performed while the pedestal or the paper feed cassette accommodating the paper of size B5R is not set in the main body. At this time, for example, even if a sheet of size B5R is set to be able to be fed from the manual sheet feeding port, the automatic sheet selection function does not work as described above, and as a result, the operator is forced to perform a complicated sheet exchange operation. There was a problem such as a result.

The present invention has been made to solve the above-mentioned problems, and by making it possible to specify the size of paper to be manually fed, automatic paper selection mode, multiplex paper feeding, even when manual paper feeding is performed. An object of the present invention is to provide a copying machine capable of executing a copying sequence according to the copying mode and the double-sided copying mode.

[0082]

As described above, according to the present invention, when the width detecting means detects the width of the manually fed paper, the manually fed paper size candidate can be recognized and any of the recognized paper size candidates can be recognized. Since the size of the recording medium fed from the manual paper feeding means can be recognized when selected by the selecting means, even if the permitting means sets the automatic paper selecting mode, the multiplex copying mode, or the double-sided copying mode by the mode setting means. Since it is permitted to feed the recording medium from the manual paper feeding means to execute the copy sequence, it is possible to cause the manually fed recording medium to execute a copy sequence such as automatic paper selection, multiple copying, double-sided copying. .

Further, since the specified manual paper feed size is stored in the storage means, it is possible to continuously specify the manual paper feed according to the stored manual paper feed size.

Further, since the display control means sequentially reads out the size candidate data stored in the size storage means in accordance with the predetermined priority and displays it on the display, a desired size data among the size candidate data corresponding to the detected paper width is selected. Size candidates can be displayed.

Further, since the display control means sequentially reads out the size candidate data stored in the size storage means on the basis of the priority order according to the width information detected by the width detection means and displays it on the display unit, the detected paper width is displayed. Of the corresponding size candidate data, the desired manual feed size can be displayed as the earliest candidate.

Furthermore, since the display control means reads out the size candidate data stored in the storage means and displays it on the display first, the desired manual feed size once selected can be displayed as the first candidate.

Further, since the display control means performs the priority display of the size candidate data based on the instruction state of prohibition or permission of the priority display control by the instruction means, the priority display can be selectively executed.

Therefore, there is an effect such that the copy sequence according to the automatic paper selection mode, the multiplex copy mode, and the double-sided copy mode can be normally executed even when the manual paper feed is performed.
