Abstract

PURPOSE:To make plural types of originals mountable at the same time as well as to aim at improvement in controllability, by inserting an original partition member into each end of plural types of original groups to be mounted on an original feeder, detecting this insertion, and processing and controlling each original group independently. CONSTITUTION:An original partition member 13, having a notch 13a as compared with the conventional regular original 14, into space between plural original groups 32 (33-35) different in type, and mounted an original feeder (RDF) body 12. And, each original is fed to an original mount from the RDF by an original feed roller, but in the midway, the original interrupts optical sensors 11a and 11b, and in case of the ordinary oridinal 14, it simultaneously interrupts and ducks through at the same time, but if deformed partition paper 13 is passed through, a time difference is produced between signals of both sensors 11a and 11b by the notch 13a, so that this difference is judged, delivering a corresponding signal to the body side from the RDF, and it is so judged that one type original group has been processed, thus copying is suspended. Thus, plural original groups different in type can be set at a time, and controllability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image forming apparatus, and particularly to a classification detection means for a group of documents in an image forming apparatus equipped with a document feeder.

(Prior Art) Conventionally, a feeder (hereinafter referred to as RD
The printer F (referred to as "F") is configured to copy/print (hereinafter simply referred to as "copy") all set originals in the same mode.

(Problem to be Solved by the Invention) For this reason, when copying multiple groups of originals of different types, one type of original group is set and each time each copy is completed, the original groups are I had to replace it, which was extremely cumbersome to operate.

The present invention has been made by focusing on the problems of the conventional examples as described above, and provides an image forming apparatus that can set a plurality of different types of original 1i4/document groups at once within the capacity range of RDF. intended to provide.

[Means for solving problems]

Therefore, the present invention attempts to achieve the above object by inserting a partition member between each of the nine different document groups to detect the division.

(Function) With the above-described configuration, a plurality of document groups of different types can be set on the feeder at once and each can be processed independently.

〔Example) The present invention will be explained below based on examples.

FIG. 1 is an explanatory diagram of an embodiment of the RDF according to the present invention, and FIG. 2 is a diagram showing the main part configuration of an example of a copying apparatus using this RDF.

(Configuration) In FIG. 1, IA is a side view of the RDF, and IB is a top view.
(consisting of a pair of sensors 11a and 11b) is provided. Reference numeral 13 denotes a document partition member (paper) that is inserted between groups of different types of document, and has a cutout portion 13a at the right end compared to a normal regular document 14 (shown with only the right end cut away). ing.

(Operation) While the document is being sent from the RDF to the document table, the document is detected by the optical sensor 11a.

Since the document 14 is usually rectangular, it simultaneously blocks both sensors lla and llb and passes through them at the same time. Therefore, both sensors are turned on or off at the same time, but when the modified partition paper 13 shown in 13 is passed through, there is a time period in which the rear end blocks the sensor 11a but does not block the sensor llb. . At this time,
That is, when the outputs of each sensor lla and llb are different,
It determines that there is a partition paper 13 in the document, sends a corresponding signal from the RDF to the main body side, determines that processing of one type of document group is completed, temporarily suspends copying, and proceeds to the next process. This is how it works.

FIG. 3 shows an explanatory diagram of the order in which document groups are set in the RDF. The manuscript group 32 is divided into 3tj of 5 sheets (first time 33), 3 sheets (second time 34), and 4 sheets (third time 35), respectively.
Then, each document partition paper 13 is inserted between each group. By placing these as they are on RDF,
Each document group 35°34.33 can be processed independently.

(Structure/Operation of Main Parts of Copying Apparatus) Next, the structure of main parts of an example of a copying apparatus using the above-mentioned RDF will be explained based on FIG. 2.

21 is a main body keyboard unit, 21a is a next copy number indicator, 21b is a copy button, 21c is a copy number display segment, 21d is a continuous mode key, 21e
is the 10 key for numerical input, 21f is the setting return key,
12g is a partition counter segment.

22 is the main body CPU, 22a is the RDF RAM, 2
2b comes with an RDF partition counter. Also, 2
3 is the CPU for RDF, 24 is the RD shown in FIG. 1 above.
F, and includes a pair of optical sensors 11 for detecting document partition sheets 13 inside the main body. 25 is a continuous mode F/ set by the main body keyboard unit 21.
F (flip-flop), and 25a and 25b are each A
It is an ND circuit. Also, in Figure 1, A1. A2゜＾3. A4
indicates various signals.

Hereinafter, the operations will be explained based on FIG. 2 and with reference to each operation sequence flowchart in FIG. 4.5. FIG. 4 shows a sequence flowchart of the setting operation before the start of copying, and FIG. 5 shows a sequence flowchart of the operation after the start of copying.

When the continuous mode key (FIG. 2, 21d) is OFF: the setting operation is unchanged from that of conventional copying, and the operation sequence during copying is shown in FIG. First, when the copy button 21b is activated (step 551), since it is not a continuous mode, the judgment in step S52 is to proceed to the NO1 side and start copying (step 353), and in step S5
4, when the RDF 24 detects the document partition paper 13, the signal A4 in FIG.
The signal is sent to the F CPU 23, and further a signal A3 is sent. These are input to each terminal of both AND circuits 25a and 25b, and the output of the continuous output F/F 25 is Q=0.
Since Q=1 (discontinuous mode), a signal is manually inputted from the AND circuit 25b to the main body CPU 22 via the signal (line) A2. When the CPU 22 detects this signal, it sends a signal to the RDF CPU 23 to collect the original partition paper 13 without copying it.

At the same time (step 555), the next copy number indicator 2
1a is turned on (step 356), and the system waits for input of the number of copies of the next group of originals (step 557).

Next, input the number of copies of the next group yX by using the 10 key 21e and press the copy button 21b.
Copies the specified number of copies. This process is repeated until all groups of various originals have been copied (step 558). Conventional partial copying can be performed in this mode.

2) When the continuous mode key 21d is on (“program mode”).

The setting method is based on the flowchart in FIG. That is, the process advances to continuous mode (YES) in step S41. The moment you press the continuous mode key 21d, all the RDF areas in the RAM 22b become zero, and the RDF partition counter 22b
is also set to zero (step 342), and the RDF RAM
22a (step 543), and the value of the partition counter 22b is incremented by 1 from the current value of 1'' (step 544).

Thereafter, the partition counter segment 21g indicates the immediate value of the partition counter 22b (ie, "2" is displayed for the second document group, and "n" is displayed for the nth document group). When "l" is displayed on the partition counter segment 21g, enter the set number of copies for the first copy using the 10 key 21e and press the setting return key 21f. This value is stored in the first address of the RAM 22a, and the value is stored in the memory of the RAM 22a. The address is incremented by 1, the partition counter 22b is incremented by 1, the display of the partition counter segment 21g becomes "2", and the state is set to wait for input of the second copy of the document.

Thereafter, by manually inputting the number of copies of each document group using the 10 key 21e (step 545) and pressing the setting return key 21f, the number of copies of the document group set under the RDF 24 is sequentially set corresponding to the number indicated by the partition counter segment 21g. The set number of copies is then stored in the RDF RAM 22a.

When the settings for all the document groups to be placed on the RDF 24 are completed (step 346), the copy button 21b is pressed to start the copying operation (step 547).

Thereafter, the operation flowchart moves to FIG.

That is, when the copy button 21b is pressed after setting (step 551), the process proceeds to the YES side for the continuous mode based on the determination in step 552. First, return the address of the RDF RAM 22a that was set and stored earlier to the first address,
The value of the RDF partition counter 22b is roughly set to "1" (step 559). Partition counter segment 21g
"1" is displayed. The RDF RAM 22a value is transferred to the copy number counter section 22c of the main body CPU 22, and the value is shown in the copy number segment 21c (step 560).

Copying of the first set of documents at the bottom of the RDF 24 is started (step 561), and the period up to the time when the document partition sheet 13 is detected is determined to be the first set. When the optical sensor 11 detects the document partition paper 13 (step 562), the RDF
24 to the RDF CPU 23, and further, a signal is inputted to one terminal of each of the AND circuits 25a and 25b through the signal A3. On the other hand, since the output of the continuous mode F/F 25 is continuous mode selection, Q=1. Q=O, and from these, a signal is sent from the AND circuit 25a to the RDF CPU 23 through the signal A1. Then, the detected partition paper 13 is collected without being copied (Step 563), RD
F RAM 22a address and RDF partition counter 2
2b values are each incremented by 1 (step 564). In this way, the information of the second part of 1g is called up and displayed in the two segments 21c and 21g, and automatically the next L'2
Copying continues until the partition paper 13 is detected.

The above operations are repeated until all document groups on the RDF 24 are processed. It is possible to copy the required number of copies of each document group set in this manner without requiring means for replacing each group.

In addition, if the copying machine is equipped with a sorter, if the bin position at which the sorting starts can be arbitrarily set using a hard switch, etc.
To the unused bin group after the bin in which they were sorted,
If you can set the following sorting of originals using a hard switch, etc., you can combine this with setting various groups of originals at once, copy the required number of copies of each group of originals, and place each one in a separate bin. The ability to sort allows copy programming/automation to be taken one step further.

(Other Embodiments) In the above embodiments, the document partition paper 13 was detected by the optical sensor 11, but the detection means is not limited to this, and two mechanical detection claws may be used. This method is effective when it is difficult to identify a document using an optical sensor in available RDF, such as a group of highly transparent documents.

Although the above embodiments have been described with reference to a copying machine, it goes without saying that the principles of this invention can also be applied to other image forming/recording apparatuses having feeders.

(Effects of the Invention) As described above, according to the present invention, the document partitioning member is configured to detect and control breaks between a plurality of types of document groups. It is now possible to process each type independently without requiring means to replace each type.
