Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copy sorting control method in a copying machine equipped with a copy sorting device.

Conventionally, as a copy sorting device used in a copying machine, a method has been proposed in Japanese Patent Publication No. 44-216 Gin etc. in which a paper receiving device is rotated or translated in parallel at the end of a copy repeat operation to shift the position of the next copy stock.

In this method, the paper receiving device is moved at the end of each copy repeat operation, so when the operator takes out the copies after making all the copies, the paper receiving device is moved one more time to remove the extra copies. A sorting operation is performed. Therefore, if the copy sorting device is operated in conjunction with the document feeding device at the same timing, an unnecessary copy sorting operation will not be performed after the copying operation is completed. However, if you do this, you can copy multiple originals one by one.
When a set of copies is made and multiple copies are made by repeating the process, the copies are sorted one by one, and it is not possible to sort one copy at a time, so there is no point in sorting. The main object of the present invention is to provide a copy sorting control method that can eliminate unnecessary copy sorting operations.

Another object of the present invention is to provide a copy sorting control method that allows copies to be sorted one by one when a document feeder is used to make copies one by one.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the copying machine 1 is equipped with a copy sorting device 2, and this copy sorting device 2 moves in the direction of the arrow in the figure to shift the position of the copy stock, thereby ejecting the copy stock from the main body of the copying machine. Copy 3 is sorted.

The copying machine 1 is also provided with an operating lever 4, and is configured such that the copy sorting device 2 can be operated, that is, moved, by manually operating the operating lever 4. The document feeder 5 is set and used on the copying machine 1, and moves the document inserted through the document insertion slot 9 to the copying position P.
After the copying is completed, the document is sent to the document stocker 6. As shown in FIG. 2, the number of repeat sheets is set to one and multiple originals 7a are
7c are inserted into the document feeder 5 through the document insertion slot 9 and copied, the documents 7a to 7c are copied one by one, and the copy sorting device 2 copies the copies 3a as described below.
- Perform the sorting of 3c one part at a time. Also, as shown in Figure 3, if the number of reheat sheets is set to 2 or more, copy 3
A to 3c are sorted by the sorting device 2 for each document. FIG. 4 shows a flowchart of this embodiment.

When the main switch of the copying machine 1 is turned on, the set number of repeat copies is first checked. When the number of repeat sheets is two or more, the copy sorting device 2 is operated, but when the number of repeat sheets is one and there is no document feeder 5, copy sorting is meaningless, so the copy sorting device 2 is not operated. When the number of repeat copies is set to two or more, a series of copy cycles is started by turning on the print switch. Conventionally, the copy sorting device is operated when copies have been made for the number of repeat sheets and the repeat end is reached and the final copy is discharged, but in this embodiment, the copy sorting device 2 related to the next copy cycle is operated. This signal may be a print signal, a signal delayed by a timer,
Alternatively, it may be a signal obtained from an optical system or a transport system. It is desirable to set the operation timing of the copy sorting device 2 immediately before the next copy is ejected, that is, the copy is ejected after the sorting device completes its operation. Therefore, in this embodiment, when the operator attempts to take out copies after making all copies, the copy sorting device 2 does not operate unnecessarily. On the other hand, when the document feeder 5 is used and the number of repeat sheets is two or more, the copy sorting device 2 is operated in the same manner as described above. When the number of repeat copies is 1, it is common to make copies of multiple originals one by one to make some copies, and then repeat this process to make multiple copies. The copy sorting device 2 is activated at the moment when the document ejecting operation from the document stocker 6 is detected, or the copy sorting device 2 is operated at the timing when the document ejecting operation from the document stocker 6 is detected, or the copy sorting device 2 is operated at the timing when the document ejecting operation from the document stocker 6 is detected. The sorting device is activated by a signal related to the P cycle, eliminating the need for manual sorting work later. FIG. 5 shows a circuit for driving and controlling the copy sorting device 2, and FIG. 6 is a timing chart when copies are made of two originals with the number of repeat copies set to three. First, the print switch is pressed or a document is inserted into the document feeder 5, a print signal S1 is output, and a copying operation is started. When three copies of the first original are completed, a repeat end signal S2 is generated. This repeat end signal S2 is the one-sheet set signal S
3 is inverted by the inverter U1, and the AND circuit U
2 and sets the lower flip-flop F1. The output signal of the flip-flop FFl passes through the AND circuit U4 by the output of the inverter U3, and sets the timer T1.
Thereafter, a print signal is issued to start a copying operation for the second document, and the print signal S1 is output from the flip-flop FFl and passes through the AND circuit to set the flip-flop FF2. Flip flop bottom F2
The output signal passes through OR circuit j and sets timer T2. The timer T2 then produces an output signal 0UT after a certain period of time, which output signal 0UT activates the copy sorting device 2. Further, the timer T3 is reset by the output signal 0UT of the timer T2 and outputs an output signal after a certain period of time. This output signal passes through the OR circuit U7 and resets the flip-flops FFl and FF2. When three copies of the second original are completed, the repeat end signal S2 is output from the inverter U1 and passes through the AND circuit to set the flip-flop FF1.

The output signal of the lower flip-flop F1 passes through the AND circuit U4 according to the output of the inverter j, and sets the timer T1. However, since the next copy operation is not started, the lower flip-flop F2 and timer T2 are not set, and the copy sorting device 2 does not operate. The timer T1 outputs an output signal after a certain period of time t1, and this output signal is sent to the OR circuit U.
7 to reset the flip-flop FFl. Further, FIG. 7 is a timing chart when three originals 7a to 7c are copied one by one using the original feeding device 5 and this is repeated twice.

In this case, since the number of repeat sheets is set to one, a one sheet set signal S3 is applied to the inverter U1 and the AND circuit j. Every time a document 7a to 7c is inserted into the document feeder 5, a print signal is generated and a copy is made, and the discharge of the copy is detected by the paper discharge detection means and a paper discharge signal S4 is generated.
is obtained. Flip-flop FF3 receives the paper discharge signal S.
It is reset at the rising edge of 4 and set at the falling edge. The document feeder 5 is provided with a detection means for detecting opening/closing of the cover 10, and after making a partial copy of the three documents 7a to 7c, the cover 10 is opened from the document stocker 6 to transfer the documents 7a to 7c. When it is taken out, a cover opening/closing signal S5 is output from the detection means. flip flop FF
4 is reset by this cover opening/closing signal S5, and the output signals of flip-flops FF3 and FF4 and the one-sheet set signal S3 are ANDed by an AND circuit U8. The output signal of the AND circuit j passes through the OR circuit j and sets a timer T2, and the output signal of the timer T2 drives the copy sorting device 2 and sets the timer T3. The output signal of timer T3 passes through OR circuit U7 and resets flip-flops FF3 and FF4. In this way, the copy sorting device 2 operates every time a portion of the copy is completed.
In another embodiment of the present invention, in the above embodiment, when the number of repeat sheets is 1 and the document feeder 5 is used, as shown in FIG. The copy sorting device 2 is activated by the signal. FIG. 9 shows a circuit for controlling the copy sorting device 2, which operates in the same manner as in the above embodiment when the number of copies to be repeated is set to two or more. However, the output signal of the flip-flop F1 is applied to the AND circuit via the diode D1 and to the AND circuit via the OR circuit U9, and the output signal of the flip-flop FF2 is directly applied to the timer T2. FIG. 10 is a timing chart when three originals 7a to 7c are copied one by one using the original feeder 5 and this process is repeated twice. When the document feeder 5 is set on the copying machine 1, a document feed reset signal S6 is generated, and this signal S6 causes a repeat end signal S2 to pass through the AND circuit Ull and set the lower flip-flop F5. Also flip flop FF
5 is reset by the print signal S1, and the output signal of the flip-flop FF5 passes through the diode D2, and by the output of the inverter j, passes through the AND circuit U4 to the timer T.
Set to 1. The cover opening/closing signal S5 passes through the AND circuit UlO and sets the flip-flop FF6 in response to the document feeding reset signal S6. The output signal of the lower flip-flop F6 passes through an OR circuit, and then passes through an AND circuit U5 using a print signal S1 to set a flip-flop FF2. The output signal of flip-flop FF2 is the timer T.
Set 2. The output signal 0UT of the timer T2 activates the copy sorting device 2 and also sets the timer T3. The output signal of timer T3 passes through OR circuit U7 and diode D3 to reset lower flip-flop F5.
Compared to FIG. 5, this circuit is designed so that no unnecessary sorting device operates after the final copy. In the above two embodiments, when a plurality of originals are copied multiple times one by one using the original feeder, the copies are sorted in conjunction with the signal from the original ejection operation, but as shown in FIG. It is also possible to set the number of original sheets or the number of sorted sheets in advance, and to automatically operate the copy sorting device when the number of copies reaches the set number. Also, as shown in Figure 12, by pressing the set button after making one copy of multiple originals, the number of originals (separated number of sheets) is automatically set, and each time copies of the set number of originals are completed, copies are made. It is also possible to activate a sorting device. Furthermore, in the above example, the copy sorting device operates when the number of repeat copies is other than 1, but this is not limited to 1 and can of course be set freely as shown in Figure 13. be. As described above, according to the copy sorting control method according to the present invention, copies are sorted after each series of copy cycles is completed using signals related to the next series of copy cycles, so it is possible to eliminate unnecessary copy sorting. .

Further, when copying a plurality of originals one by one using a document feeder, the copies can be sorted one by one by sorting the copies each time one copy of the plurality of originals is completed.
