Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus that circulates a manuscript made of handwritten, typed, printed, or copied paper, etc., and obtains copies of several pages for each copy. .

Conventionally, as a method of obtaining several copies of one copy of several pages, 1
A method of making the required number of copies from the same original at once, feeding each copy one by one to a different copy distribution slot, and sequentially replacing the original to make copies of the necessary documents. 2. Using an automatic document feeder (hereinafter referred to as ADF) There is a method in which the original is returned to the top of the ADF after one copy has been made, and the original is circulated as many times as necessary to obtain the required number of copies with one ejection port.

However, method 1 requires a copy dispensing port for the required number of copies, which increases the size of the apparatus, and also has the drawback that the mechanism for assembling the apparatus for binding the obtained copies becomes complicated and the apparatus also becomes larger. On the other hand, with method 2, the document passes through the ADF only the required number of times, which may cause the document to fold or slip easily.As a result, the function of the part that separates the documents in the ADF one by one deteriorates, and This method has drawbacks such as sending out more original documents at the same time and causing frequent paper jams. Also, the platen of a copying machine, i.e.
A similar type of copying is performed by arranging document storage devices very close to both sides of the exposure position and moving the document in one document storage device to the other document storage device via the exposure position. It has also been proposed that
Publication No. 7084). However, in the above proposal, the shelf itself, which has a large number of pockets for storing manuscripts, is moved up and down to position the pockets from which manuscripts are stored and taken out. Due to the large weight and inertia, not only the positioning cannot be performed accurately and at high speed, but also a large driving force is required, which increases the size of the device and increases costs.

{21 Since the manuscript is inserted into and removed from each chamber using pressurized fluid from a fluid source,
Insertion and extraction are not reliable or reliable enough.

[3- Since a pair of shelves is required on both sides of the exposure position,
This increases the size of the device and increases costs.

■ When only a part of the originals on the shelf are copied, the original storage status will be different before and after copying (in other words, the originals that were centrally managed on one shelf before copying will be (are stored separately on two shelves), making storage and organization of manuscripts complicated. There are drawbacks such as.

The present invention provides a copying apparatus that makes several copies of several pages per set, which has a single copy outlet in order to facilitate combination with a bookbinding device, etc., and minimizes the number of times the original passes through the ADF. In addition, only one document storage device is required, and documents can be taken in and out at high speed and reliably.

As shown in FIG.
, document feeding mechanisms 11A, 11B, and ejected document receiver 9.

Here, the part that is particularly important to the present invention is the document storage mechanism 2. The document storage box 21b, which is a part of the document storage mechanism 2, has many small rooms partitioned by partition plates 2-b.
In addition, there is a guide for placing one original into a designated one of the small rooms partitioned by the partition plate 2-b of the original storage box 2-b according to a control signal from a controller (not shown). 2-a3, and a document selection/retrieval mechanism 2-c that simultaneously selects documents one by one from designated compartments 1 of the document storage box 21b in response to control signals from the controller. and are available. Of course, without using the automatic document feeder 1, the documents may be manually fed one by one and stored in the small compartment of the document storage box 2-b, or the originals may be directly distributed one by one manually into the small compartment. It's okay. The details of the present invention will be explained below along with its operation with reference to FIG.

The operator (the person who combines the original and the overlay 6 to obtain a copy) first inserts the original into the automatic document feeder (
(hereinafter referred to as ADF) 1, and press the start button of the operation keys (not shown).

Then, the ADFI feeds out the documents one by one.
In FIG. 1, a so-called bottom feed type ADF is shown. Although this is excellent in terms of ease of document setting, etc., a top feed type ADF may also be used. The entrance of the storage box 2-b is open, and as described above, there is a partition plate 2-bl inside to divide the storage box into the required number of rooms, creating small rooms. Now, the originals are transferred one by one in the direction of arrows X and Y by the original feeding mechanism 11A, and reach the original storage selection mechanism 2-a. The guide 21a3 of the document storage selection mechanism 21a is connected to a stepping motor 21a4 and a screw 21a5.
The originals can be moved up and down along the respective entrances of the small chambers, set at predetermined positions by the controller, and documents are set one by one in the four chambers of the storage box 2-b, for example, one by one from the bottom. A gate mechanism 2-b2 is provided at the exit of each of the small chambers.
is installed. When at least part or all of the originals set in the ADFI are set in the small chamber in the storage box 2-b, the document selection/retrieval mechanism 2-c moves along each exit of the small chamber under the control of the controller. (up and down) to select and take out the originals one by one. To take out the original, use the stepping mode.
This is done by setting the guide 2-c3 and the gate opening/closing mechanism 2-c6 at predetermined positions using the screw 2-a4 and the screw 2-c5, and operating the gate opening/closing mechanism. In this embodiment, the small chamber of the document storage box is sloped, and the gate mechanism 2-
When b2 is opened, the document is taken out so that it slides out under its own weight. The taken out original is fed onto the platen 16 along the arrow Z from the original feeding mechanism 11B', registration is determined by the original positioning device 14, and a copy is taken. If the used original is not to be used again, it is ejected to the ejected original receiver 9 by the original ejection switching device 10. When the document is to be used again, the document is moved along the arrows W and Y, passes through the document feed mechanism 11A and the document storage selection mechanism 21a, and is stored again in the original small room of the document storage box 21b.
In addition, 5 and 5A are supplying and winding mechanisms for the overlay film 6, 7 is a mirror for optically scanning the original, 8 is an optical system for forming an image of the original on the photosensitive drum, and 12 is the overlay film 6. The position sensor is a position detector, all of which are well known in the electronic reproduction technology, so a description thereof will be omitted. Second
The figure shows a schematic configuration of another embodiment of the present invention.
The same symbols as in the figures represent the same parts.

Note that, in this figure, each function shown in FIG. 1 is largely omitted for simplification. As is easily understood, in this embodiment, the original fed by the ADFI is combined with the overlay 6 to make a copy before being put into the small room of the original storage box 2-b, and then the original feeding mechanism 11A and By the document storage selection mechanism 2-a,
In the same way as described above, the originals are stored one after another in the small chambers in the original storage box. By adopting this configuration, the time from starting the copying machine to obtaining the first copy is shortened. can do.
As described above, according to the present invention, the original does not have to pass through the ADF as many times as necessary for copying, so damage to the original is less likely to occur, and paper jams and the like are reduced.

Furthermore, since the required number of copies can be processed all at once using one copy output port, it becomes easy to combine with an automatic bookbinding mechanism. Furthermore, according to the present invention, the following excellent effects are achieved. [1' Since only one document storage box is required, increase in size and cost can be avoided.

'2} The document storing and selecting mechanism and the selecting and extracting mechanism, which are lightweight and have low inertia, are driven and controlled to select the chamber in which the document is to be placed or taken out, so only a small driving force is required, and high-speed and reliable positioning is possible. It becomes possible.

Glue: The passenger compartment is tilted so that the originals will slide down under their own weight, so there is no need for special power to store and remove manuscripts from the compartment, and the storage and removal can be done reliably and quickly. be able to.

[4'] The originals that have been copied are returned to the same small room where they were originally stored, so even if the originals in the original storage box are copied in discrete order or only a part of them, The originals are stored in the box in exactly the same order as before copying.

Therefore, the storage and organization of manuscripts can be ensured. In any of the embodiments described above, the original document storage box 21b can be replaced with a cassette type, and in this way, the originals can be stored in a small room in a predetermined order, so they can be stored frequently. This has the advantage of simplifying the handling of manuscripts used for other purposes.
