Abstract

PURPOSE:To eliminate such a troublesome operation as considering a direction for setting an original and shifting the original, etc. when copying a book-shaped original by constituting the titled device so that only an optional one page can be copied. CONSTITUTION:This device is provided with a page designating key 13 and also provided with a page designating mode display use LED 14 which is lighted when this page designating key 13 is depressed. In such a case, the page designating key 13 is selected in case when only one page copy of the opposite side to an original reference side is executed. When this page designating key 13 is depressed, a feed timing is set to a mode 2 from a regular mode 1 by the control of a CPU and only the image of one page portion of the opposite side to the original reference side becomes effective and remains on a photosensitive body. The feed timing of a transfer paper is delayed from a regular process so that the image of this photosensitive body is transferred and the copy of only one page of the opposite side to the original reference side is obtained.

Description

[Detailed description of the invention] Technical field The present invention relates to a copying apparatus.

2. Description of the Related Art In general, copying machines are used in various ways, and there are cases where it is desired to copy not only sheet-like originals but also book-like originals. Regarding the copying of this book-like original, there may be cases in which it is desired to copy not only both facing pages, but also only one page. In order to meet these demands, conventionally the optical system or document table has been made half-returnable, and when it is necessary to copy both pages of a book-like original, the optical system or document table is fully scanned, but only one page can be scanned. During copying, there is a system in which only the page on the reference side of the original is scanned, and the optical system or the original table is half-returned. In this method, if the model is a copying machine with a fixed document table, it is necessary to shift the document halfway toward the document reference side when copying a page that is not on the document reference side. or,
If the copying machine uses a moving document table, by shifting the document by half in the same way as in the case described above, half of the document 1 will protrude from the document table 2 as shown in Figure 6, so support it with your hand and copy. Or, it is necessary to turn over the document 1 by 180'' from the state shown in FIG. 7(a) to the state shown in FIG. One thing that repeats 1
The top and bottom of the copies obtained for each page will also be out of order. This point.

Conventionally, as shown in FIG. 8, there is a device which has a continuous page copying function so that copies 4 of two pages can be obtained for each page of a book-like original 3. When this page continuous copying function is used, either two pages are copied or only the original reference side is copied, so even if one page of the original reference side of the book-like original 3 does not need to be copied, two pages are copied. This is uneconomical. Furthermore, even with book-like original 3, the order of the pages in the resulting copy will be incorrect, depending on whether it is a right-hand-opening original (vertically written original) or a left-hand-opening original (horizontal writing original), and the order of the pages in the resulting copy will be incorrect. It's bad.

the purpose The present invention was made in view of these points.

It is an object of the present invention to provide a copying device that can copy book-like originals with extremely high operability.

Structure In order to achieve the above object, the present invention provides a page designation key for designating copying of only one page of a book-like original, and sets the copying process at a different timing from the normal timing in the copy mode using this page designation key. The present invention is characterized in that a control means is provided for controlling each timing.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. First, in this embodiment, as shown in FIG.
Regarding copies of the book-like original 6 set on the contact glass 5, there are not only double-page spread copies as shown by ■, but also fly copies of only the reference side of the original as shown by ■.
It is possible to arbitrarily perform any fly copy on the side opposite to the original reference side as shown in FIG.

In order to realize this, the configuration of the operation panel 7 of the copying machine is shown in FIG. Count key 10. In addition to the density adjustment key 11 and the AE key 12, a page designation key 13 is provided, and an LED 14 for displaying a page designation mode that lights up when the page designation key 13 is pressed is also provided. Here, the page designation key 13 is selected in the mode (3) in FIG. 1, that is, when only the fly copy on the side opposite to the reference side of the original is to be performed. This page specification key 13
By pressing , the timing of the copy process is controlled by the CPU as described below.

This control will be explained with reference to the timing chart of FIG. 3 and the flowcharts of FIGS. 4 and 5. First, when copying, the page designation key 13 is checked as shown in FIG. 4. If the 0 page designation key 13 is pressed, the page designation flag is set, but if the page designation key 13 is not pressed, The page specification flag is reset. Then, a timing mode is set as shown in FIG. 5 in accordance with this page designation flag. Now, if the page designation key 13 is not pressed and the page designation flag is not set, the copying process can be carried out in the normal timing mode 1 and returns as is, but the page designation key 13 is pressed and the page designation flag is set. If so, the erase timing and paper (transfer paper) feeding timing of the copying process will be set to normal mode 1.
Mode 2 is set from .

Under such settings, the copy operation is performed at the timing shown in FIG. First, by pressing the print key 8, a copying operation is started. Then, the charger is turned on and the surface of the photoreceptor is uniformly charged, and after a short delay, the exposure lamp for illuminating the document is turned on, and the drive motor of the exposure optical system also rotates in the normal direction to start exposure scanning of the book-shaped document 6. This is done from the original reference side. This is a common operation timing in any mode. Therefore, if the book-like original 6 is in the normal copy mode shown in FIG. In the image area, only the site erase according to the size is performed, and then the entire surface erase is performed again at the rear end portion of the image.

Then, the transfer paper is fed by a registration roller at a predetermined timing so as to be synchronized with the leading edge of the developed image on the photoreceptor, and undergoes image transfer. In addition, in the above explanation, the time of the time axis of the timing chart shown in FIG. can also be obtained even if it is a fly copy of the reference side.

Therefore, in the page specification copy mode using the page specification key 13, the erase timing and paper feed timing are set to mode 2 and the copy operation is performed (the operations of the optical system etc. are the same), and the image on the photoreceptor is When you look, ■ya■
As in the case of the embodiment described above, an image of the fly on the document reference side is also formed, but as shown in erase (mode 2), the entire surface of this fly continues to be erased, so the latent image is erased from the photoreceptor. It will disappear. Then, only the fly image on the side opposite to the document reference side becomes effective and remains on the photoreceptor. In order to transfer the image on the photoreceptor, the timing of feeding the transfer paper is delayed compared to the normal process, resulting in a copy of only the fly on the side opposite to the document reference side.

As described above, according to this embodiment, it is possible to make copies in any of the modes ① to ② shown in FIG. It is only necessary to specify which page to copy from, and there is no need for troublesome operations such as setting the original in consideration of its direction, whether it is a vertically written original or a horizontally written original. Further, it is possible to make copies on any left or right side with the original set normally, so there is no wastage of copying, and it is extremely easy to operate.

In the above description, a method using a fixed original/optical system scanning method has been described, but the present invention can be similarly applied to a method using a fixed optical system and a moving document table. In particular, if the document table moves like this,
The document does not protrude from the document table, and there is no need to worry about supporting it.

Effects The present invention provides a page designation key as described above, and when the page designation key is pressed in the page designation copy mode, the copying process is performed at a timing different from the normal timing, and copying is performed only at an arbitrary time. Therefore, when copying a book-like original, it is possible to obtain a copy in the desired format with extremely good operability without having to consider the orientation of the original or shift the original. It is something that can be done.
