Abstract

PURPOSE:To process with only one line making unnecessary to provide the means which displays the position of an original placed on an original platen according to the size of the original by providing a control means that stays a reading means at a prescribed position on the original platen. CONSTITUTION:By the control means not shown in figure, the center reference position 3b of a carriage 3 is moved and stopped at the center part of an original 1, that is, the position where a binding part is to be placed, along with the carriage 3. Next, the binding part is placed to be aligned with the line 3b, a copying operation being performed. And the carriage 3 scans the one side page of the original 1 along with an original surface, transcribing it on a recording paper with a regular method. After that, the carriage 3 scans the other side page of the original 1, transcribing it on the other paper. Thus, by providing the line 3b on the carriage 3 and moving it to a prescribed position with the carriage 3 corresponding to the size of the original 1, only one line, the line 3b, can process even when the size of the original 1 that is placed on an original platen 2 varies.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a copying apparatus equipped with a page speed copying function that transfers two pages onto separate recording sheets, for example, while a booklet is opened and placed on a manuscript table. .

[Technical background of the invention and its problems] In recent years, copying devices with additional functions such as a variable magnification function, an automatic density adjustment function, and a continuous page copying function have been widely used for the purpose of improving the efficiency of OA. It has started to be done. Among these additional functions, the page continuous copying function is to transfer two pages onto separate recording sheets, for example, while opening a booklet or the like and placing it on a document table.

In general, a copying device with such a page speed copying function prints a transparent document with a label or the like that indicates the position where the binding margin should be placed when the document such as a booklet is opened, that is, the center reference position. It includes a table, a movable scanning optical system (hereinafter referred to as a carriage) that is placed under the document table and performs exposure optical scanning along the surface of the document, and a scanning means that scans the carriage.

Then, the original is placed on the original table so that the binding margin is aligned with the central reference position of the original table, and the copying apparatus is operated. First, the carriage scans one page of the document onto the surface of the document, performs exposure optical scanning, and transfers the page to recording paper. The carriage roughly exposes and optically scans the other page of the document along the surface of the document, and transfers it to another recording sheet.

However, there are various sizes of manuscripts such as booklets, and the position where the binding margin should be placed, that is, the center reference position, differs depending on the size.
It was necessary to set a center reference position according to the size of each manuscript.

[Object of the Invention] The present invention has been made in response to the above-mentioned circumstances, and it is possible to use a single display means for displaying the position of a document placed on a document table without having to provide it according to the size of the document. The purpose is to provide a copying device that can

[Summary of the Invention] That is, the copying apparatus of the present invention is a copying apparatus that transfers a document whose surface is divided into two areas to a different recording member for each area, and includes a transparent document table and a document plate on the document table. a reading means disposed below the original table and having a display means that can be seen through; a scanning means for scanning the reading means along the original table; and a control for stopping the reading means at a predetermined position on the original table. By comprising means for displaying the document placed on the document table, there is no need to provide display means for displaying the position of the document placed on the document table depending on the size of the document, and a single display device can be used to display the position of the document placed on the document table.

[Embodiment of the Invention] Hereinafter, details of an embodiment of the present invention will be described based on the drawings.

FIG. 1 is a diagram for explaining a copying apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view for explaining a carriage of this embodiment.

As shown in FIG. 1, the copying apparatus of this embodiment includes a transparent document table 2 on which a document 1 having a binding margin, such as a booklet, is placed;
A carriage 3 is provided below the document table 2 and performs exposure optical scanning along the document surface of the original M1.

Roughly speaking, this copying apparatus includes a scanning means (not shown) for scanning the above-mentioned carriage 3 along the document table 2, and a control means for stopping the carriage 3 at a predetermined position on the document table 2 in response to a predetermined signal. (not shown).

Further, as shown in FIG. 2, the carriage 3 includes an exposure lamp 3a that emits light to expose the document 1, and an exposure lamp 3a that can be seen from above the document table 2 and extends in a direction perpendicular to the direction in which the carriage 3 scans. 3, and a center reference position line 3b provided along the top of the center reference position line 3b.

In the copying apparatus configured as described above, the copying operation of a manuscript such as a booklet is performed as follows using the page continuous copying function.

First, from an operation unit (not shown) provided on this copying machine, instructions for operating the page continuous copying function and the original to be copied.
Data with a size of is input and output as a signal. At that time, the carriage 3 is controlled by the control means inputted with these signals.
The center reference position line 3b moves together with the carriage 3 to a position where the center portion of the document 1, that is, the binding margin portion, is to be placed and stops. Then, this center reference position line 3b and the original 1
Place the paper so that the binding margin of the paper is aligned with the binding margin, and then make a copy. First, the carriage 3 performs exposure optical scanning on one page of the original 1 along the surface of the original, and transfers the page onto a recording sheet using a conventional method. Next, carriage 3 is Hara @1
The other page is exposed and optically scanned along the document surface,
Transfer it to another recording paper using the usual method.

As mentioned above, since the center reference position line 3b is set on the carriage 3 and the carriage 3 is moved and stopped at a predetermined position according to the size of the document, the size of the document placed on the document table 2 is changed. Even if it changes, it can be handled with one center reference position line 3b.

Furthermore, the copyable range of the original 1 can be easily determined from this center reference position line 3b.

[Effects of the Invention] As explained above, according to the copying apparatus of the present invention, the reading means is provided with a display means that can be seen from above the document table, and the reading means is placed at the position where the document placed on the document table is to be placed. By stopping the display means at the same time, there is no need to provide display means according to the size of the document, and one display means can be used.
