Abstract

PURPOSE:To execute almost automatically a circulating type copying work, and to raise the work efficiency by placing an endless belt and an original tray on an original platen, providing an original partition plate in the tray, and also placing an invertor. CONSTITUTION:In case when an original is of one surface, a feeder 22 of an original tray 19 feeds it out to an original platen 1 in order from its final page, and contains it in an original catch tray 35 through an invertor 26 in order from the end of exposure. In this case, when both a pawl 31 and 32 of the invertor 26 are drawn in from an original carrying path and the catch tray 35 is set up in an almost vertical state, the original is accumulated in order as it was before. In case of what is called a both surface original having a picture on both surfaces of the original, one surface is exposed on the original platen 1, and thereafter, it is fed out straight once through the invertor 26, the pawl 32 is set up after its rear end is detected by a sensor 33, and at the same time the rear end of the original becomes a lead edge, and the original is returned into said original tray 19.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a circulating automatic document feeder attached to a copying machine.

When copying multiple copies of documents arranged in a predetermined page order, such as conference materials or books, it is common to use a sorter that comes with a copier, but a sorter also requires a large amount of floor space. There is a drawback that it is expensive.

Therefore, conventional methods have been used, such as the 251 or automatic stapler, in which the manuscript is circulated in page order from 1 to the customer light section of the copying machine to make copies of the required number of copies in page order, and the copies are taken out into each part and stapled with the arm of the stay 7'. There is a device that binds each copy of one volume of kopikani by using it.

However, it is no exaggeration to say that when a large number of copies are to be made in such a document circulating device, a document jam will always occur. (・There was a defect.

On the other hand, in order to avoid the above-mentioned defects, it has been proposed to sandwich the manuscript in page order in a transparent fibre/notebook, roll it up, and repeat the feeding and winding process, but this is not practical because handling the manuscript is troublesome. There appears to be no example of it being served.

The present invention has been made in order to eliminate the defects of the conventional circulation type document feeder as described above, and includes an endless belt that is in sliding contact with the document e placing table of a copying machine, and an endless belt that is placed above the document feeder. A tray (having a feeder that sequentially feeds the original stack onto the document mounting table from the bottom layer) is arranged, and the tray is partitioned into upper and lower parts, and a part that interferes with the feeder is cut out. In addition, an inverter for reversing the front and back of the document is placed adjacent to the endless belt (1).
The original inverted by the inverter is
) A conveyance path is provided to transport the original onto the partition plate of the tray, and a bypass is provided to return the copy after the copying process in the copying machine onto the partition plate of the original tray. Does it include copies? An object of the present invention is to provide a circulating type automatic document feeder that performs continuous copying work.

Hereinafter, the present invention will be explained in detail based on an example shown in the drawings.

FIG. 1 is a schematic diagram of a circulating type automatic document feeder according to the present invention.

Reference numeral 1 denotes a glass original plate of a copying machine, on which the scraped originals are exposed to light by a flash from a flash lamp 2.2 placed around the lower surface of the original. An original image is projected onto a belt-shaped photoreceptor 4 by an image lens 3.

Around this belt-shaped photoreceptor 40, a corotron 5 for uniform charging is arranged at the right end in the figure, and a developing device 6 for producing a latent latent image formed as a result of projection of the original image is arranged at the left end. The small curvature section at the lower end is equipped with a transfer/separation corotron 7 that integrates a transfer corotron that transfers the toner image developed by the developing device 6 onto the copy paper and a detack corotron that helps peel the paper. The toner remaining on the surface of the photoreceptor after the transfer is cleaned by the cleaner 8 just before the uniformly charged corotron 5 in preparation for the next process.

On the other hand, below the developing machine 6, there are provided copy paper trays 9.9 for storing sheets of different sizes, and a double-sided copy tray 10, which will be described in detail later. Peeling corotronoa and belt-shaped photoreceptor 1
A paper conveyance path is arranged between the two. Note that the paper tray 9
．． 9 sequentially feed out the stacked and stored sheets from the top layer, whereas the double-sided copying tray 10 feeds out the sheets from the bottom layer. Also, the copy paper that has been completely fed out from each of these trays is placed in the registration tray 7 provided just before the transfer point.
Needless to say, the roller roll 11 ensures that the leading edge of the paper is perpendicular to the conveyance path, and also controls the timing of sending the paper to the transfer point for registration with the developed toner image.

Now, the copy paper that has passed the transfer point is sent to the fixing device 13 by the vacuum conveyance device 12 to complete the copy.In the present invention, the completed copy is transported to the following three locations. The paper transport routes 14, 15 and 16 are set respectively.

The first is a carriage tray 17 outside the machine, similar to a regular copier.
The second is the double-sided copying tray 10, and the third is the FA document tray of the circulating automatic document feeder of the present invention, which will be described later.

As explained above, a circulating type automatic document feeder described below is mounted on a copying machine which has been added with several supporting mechanisms.

First, the document conveying device 18 using an endless belt is temporarily placed on the document table 1, and the document tray 19 is stacked thereon.

This document tray 19 has a partition plate 20 which divides the tray into upper and lower parts in the middle, and is made to be freely flapable by means of a hinge 21, as shown in FIGS. 2(a) and 2(b). mJ below the center of the leading edge of the busy tray
The document feeder 22 is connected to the document feeder 22, and the Ail of the partition plate 20 is
A notch 23 is provided in a portion that interferes with the marking 22,
Furthermore, intermittent drive feeders 24.24 are in sliding contact with J2Ii of the partition plate 20 on both sides of the notch 23 marked i'+i+.
The partition plate 20 and the intermittent drive feeder 24.24 are arranged as one and are configured to be rotatable around the hinge 2. The driving force for the intermittent drive D feeder is provided by connecting the flexible shaft 25 to a motor (not shown).

Next, the endless belt material (^゛i transportation damage゛1)

Furthermore, for the first time: “The manuscript of JI- that has been completed is published by Agency 1.
Note 'f 7 The Kt sum discharge roll 34, which is placed in front of the barter 26, sends it out to the original fθ catch tray 35.
- As shown in the figure, this tray can be selected from two states, a substantially horizontal state and a substantially vertical state 5, depending on the folds required.

Also, since the paper transport path 15 to the Fukobi River Tray] 0 intersects the paper transport path that sends out the paper from this tray, the rotatable paper transport path 36 is moved by a spring 37 as shown in FIG. A toggle mechanism is provided so that the paper transport path 360 can be fixed in two positions, and memory shape alloy springs 38 and 39 are respectively installed on both sides of the paper conveyance path 360 to sandwich the rotating shaft, and movement to the two positions is performed by attaching shape memory alloy springs 38 and 39 to either of these positions. This is done by energizing. Furthermore, the three copy conveyance paths 14, +5 and 1 leaving the mI recording device I3
In order to send the paper to either of the 7-can and 7-cans control signals, as shown in FIG.

The circulating automatic document feeder of the present invention constructed as described above operates as follows.

When an operator wants to create several copies of a multi-page document, the operator first rotates the document partition plate 20 of the document tray 19 together with the intermittent drive feeder 24 to store the document with the first page facing up. Next, the operator inputs information such as the size of the scrap paper to be used depending on the document size, a negative number, whether or not the document is double-sided, and the number of copies to be made into the built-in microcomputer memory using the keyboard of the copying machine (not shown), and then the copying process begins. Let's start.

If the document is one-sided, the feeder 22 of the document tray 19
The documents are sent to the document loading f/f stand 1 in order starting from the last page, and are stored in the document catch tray 35 (C) through the inverter 26 in the order in which exposure is completed. At this time, the claws 31 and 32 of the inverter 26 are If both of the catch trays 35 are retracted from the document transport path and the catch tray 35 is left standing in a substantially vertical position, the documents will be deposited in the original order.

On the other hand, for copies corresponding to these originals, the path 16 returning to the FA document tray 19 is first selected from among the paper transport paths that branch into three directions in front of the fixing device 13. For this purpose, the mold 40 may be controlled to be tilted to the position indicated by the dotted line in FIG.

By doing this, when the first copying operation is completed, the first generation (children's) manuscripts will be piled up in the same order on the partition plate 20 of the manuscript tray 19 instead of the soldier's manuscripts. Become. It is unnecessary to explain that the intermittent drive feeder 24 assists in the stacking and feeding of the first generation documents.

After the above steps are completed, according to the instructions from the built-in microcomputer, 1) 11 Inverter 2
The pawl 31 of No. 6 stands up so as to block the document conveyance path, and the pawl 4o of the three-branch paper conveyance path also reaches the position indicated by the horizontal line in FIG. Stops after copying for that amount. It goes without saying that it is sufficient that the required number of copies is one less than the number originally required by the operator. This is because the 1st FF 1st generation manuscript can be used as one copy. Also, the catch
It is also clear that since the copies deposited on the tray 17 are arranged in page order, there is no need for special collation.

On the other hand, in the case of a two-sided M1 original with images on both sides of the original, one side is exposed on the original table 1 and then sent straight through the inverter 26, and the rear end is detected by the sensor 33. After this, the front lift 32 is raised, and the rear end of the raw material is returned to the document tray 19 as a lead edge.

At the same time, after the copies exit the fixing device 13, they are returned to the double-sided tray 10 via the conveyance path 15 and stacked, and after one side is completely copied, the other side is copied.

It is obvious that the original document should be stored in the original gantch tray 35 in a substantially horizontal position after the double-sided copying operation is completed.

Since the unexploded IJJ is constructed and operates as explained above, it is possible to perform the cyclical copying work almost automatically by simply adding a relatively small and simple device to the copying machine. Not only is it possible to do this, but the probability of damaging the original is minimized, and of course there is no need for a device that takes up a large floor space like a notator. This has a remarkable effect on improving efficiency.

Incidentally, the force not specifically explained in the above embodiment may be provided with a self-nI2+ stage in the copy catch tray 17, and the 11th staff member returned to the tray 19 after the completion of all copying operations. A separate conveyance path for returning the original to the catch tray 17 may be provided. It is also convenient from the perspective of maintaining confidentiality, since it prevents accidents such as leaving something behind.
