BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a copying machine capable of performing copying by a combination of a function of continuously copying two continuous areas (pages) such as a book and double-sided copying with a single copy instruction.
[0002]
[Prior art]
In a conventional copying machine, copying can be performed with a combination of a function of continuously copying two continuous areas (pages) like a book and double-sided copying by one copy instruction. FIG. 35 and FIG. 36 are diagrams when copying in this combination. 35 is referred to as book double-sided copying, and FIG. 36 is referred to as page continuous copying double-sided copying. Also, in the book double-sided copy, the type of the original (right open / left open) can be specified, but here, it is assumed that the left open book or the original is copied.
[0003]
First, the book head is turned forward (front side), and in the case of a document, two documents are arranged and placed on the glass surface. First, book double-sided copy (start page: left, end page: left) is set, and copying is started.
[0004]
In the case of copying without using a memory, an image of a document closer to the front end of the document (hereinafter referred to as a left page) is copied on one side of the sheet, and the copied sheet is discharged. Subsequently, the image of the document farther from the leading edge of the document (hereinafter referred to as the right page) is copied on one side of the paper and stacked on the duplex device. In this case, as shown in FIG. 37, the message “Is there another document?” Is displayed on the liquid crystal touch panel, and the user is prompted to input a [YES] / [NO] icon. When the original is replaced and [YES] or the copy key is pressed, the image on the left page is copied to the other side of the sheet taken out from the duplex device and then discharged. Subsequently, the image on the right page is copied to one side of the paper and stacked on the duplex device. A message similar to the above is displayed. If you want to copy only one page (left page) of the next document, press the [NO] icon to display the message “Please press the copy key”. It is copied and discharged onto the paper taken out from the apparatus.
[0005]
Also in the case of copying using a memory, first, the image of the left page is stored in the reading memory, and then the image of the right page is stored in the reading memory. In this case, as shown in FIG. 37, the message “Is there another document?” Is displayed on the liquid crystal touch panel. When the original is replaced and the copy key or [YES] icon is pressed, the left page / right page are read and stored in the memory. A message similar to the above is displayed. Here, when only one page (left page) of the next document is read, when the [YES] icon is pressed, the left page / right page are read and stored in the memory. After that, the same message as before is displayed, and when the [NO] icon is pressed, the image data of the right page stored in the memory is cleared and printing is started.
[0006]
Next, page continuous shooting and double-sided copying (odd page designation) are set, and copying is started.
[0007]
In the case of copying without using a memory, the image of the left page is copied on one side of the paper, and the copied paper is discharged. When the original is replaced and the copy key is pressed, the image on the left page is copied and stacked on the duplex device. Subsequently, the image on the right page is copied onto the paper taken out from the duplex device and discharged. When the original is replaced and the copy key is pressed, the image on the left page is copied and stacked on the duplex device. Subsequently, the image of the right page is copied and discharged onto the paper taken out from the duplex device.
[0008]
Also in the case of copying using a memory, first, the image of the left page is read and stored in the memory. In this case, as shown in FIG. 37, the message “Is there another document?” Is displayed on the liquid crystal touch panel. When the original is replaced and the copy key or the [YES] icon is pressed, the left page / right page images are read and stored in the memory. A message similar to the above is displayed. When the original is replaced and the copy key or the [YES] icon is pressed, the left page / right page images are read and stored in the memory. Thereafter, the same message as before is displayed, and when the [N0] icon is pressed, printing of the image data stored in the memory is started.
[0009]
At this time, the relationship between the original and the discharged paper in the book duplex mode is shown in FIGS. 35A, 35B, and 35C, and the relationship between the original and the discharged paper in the page continuous duplex mode. Is shown in (a), (b) and (c) of FIG. FIG. 37 shows a diagram of a liquid crystal display unit with a built-in touch panel during the message display.
[0010]
When copying is performed according to the above procedure, the following problems occur.
[0011]
(1) The meaning of the [NO] key differs depending on whether the memory is used or not.
[0012]
When using the memory: Start printing (all read).
[0013]
When memory is not used: The last page is copied (there is a page to be read).
[0014]
It is conceivable that the operation becomes complicated for the user and an operation error occurs.
[0015]
(2) There is no means for reading only one page (in the case of book duplex mode).
[0016]
When using a memory: Clear one page of data already read for two pages. The time required to read the cleared page and the reserved memory capacity are wasted.
[0017]
When memory is not used: “Please press the copy key” is displayed, and the [Copy key is pressed to copy only one side. The operation is divided into two stages, and the operation becomes complicated.
[0018]
(3) Page order is not aligned when page continuous shooting is also in duplex mode.
In the page continuous shooting function, as shown in FIG. 36 (c), the page order of the discharged sheets is not aligned, and therefore, stapling cannot be performed.
[0019]
[Problems to be solved by the invention]
As described above, when scanning two images in the book double-sided mode or page continuous double-sided mode and making a copy at the end, if you try to read one image last, This eliminates the disadvantages of not being able to read and copy only those pages, or the page order of the ejected paper being out of order, resulting in poor operability. In the image forming apparatus, the meaning of the key to be instructed can be the same, only one page can be read and copied, the page order of the discharged sheets can be aligned, and operability can be improved. The purpose is to provide.
