Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper discharge control method in a copying machine with an automatic document feeder.

In recent years, copying machine systems have been equipped with not only an automatic document feeder but also a double-sided copying mechanism and a sorting mechanism for high-speed, large-volume processing. In this case, the page order of the original must not change even after it passes through the automatic document feeder, and the page order of the copy must be the same as the page order of the ejected copy. It is necessary to satisfy two conditions: they must be the same. L. However, due to layout considerations, it is preferable to satisfy these two requirements for all combinations of operation modes in the circular part, and the page order of the ejected copy may be reversed. do not have.

The present invention has been made in view of the above points, and even when introducing all operation modes, page 1 of the original and transfer paper can be adjusted.
It is an object of the present invention to provide a paper ejection control method in a copying machine equipped with an automatic document feeder, which maintains the same FI and facilitates transfer paper processing.

An embodiment of the present invention will be described based on all the drawings.

As a result, in the manual DF (automatic document feed) mode, when the original (c) is set in the original tray (b) and detected by the original setting sensor (3→), pressing the print key will cause the ADF to The linked copy cycle starts. First, after a predetermined timing has elapsed since 77n (l rotates, the electromagnetic clutch 0→ is turned on. As a result, the paper feed roller (c) and separation roller 0◇ rotate, The lowest #document on the document tray (A) is sent out.Then, when this document (C) is sent out by the pinch roller 0ne and its leading edge is detected by the leading edge detection sensor OQ, the electromagnetic clutch 01 is turned OFF. Then, the paper feed roller (C) stops.Meanwhile, the fed document QQ is transferred to the conveyor belt (G).
Contact glass (c) 1 gold is transported by. Here, after the leading edge of the document (c) has passed through the intermediate sensor zero force and a predetermined timing has elapsed, the drive motor (b) is turned off and the drive of the conveyor belt 01 is cut off. As a result, t is added to the manuscript (c).
It moves by the inertial force of the conveyor belt 01, hits the gate claw θ, and stops at the position of the gate claw O), that is, the position 7)j on the contact glass ψρ.

After such original document setting is completed, an exposure scanning operation of the exposure optical system is performed with a certain margin of timing. The timing of feeding the transfer paper and other copying processes is such that the paper is already fed a sufficient amount of time in advance for exposure scanning. Then, according to the mode set on the operation panel KUNO, the copy cycle is repeated for the set number of sheets.

When the predetermined copy circle f completes, the solenoid (L
i1) causes the gate pawl 0) to descend and retreat, and after a predetermined timing elapses, the drive motor 0◆ is turned on again, and the conveyor belt () is driven, so that the document (C) on the contact glass (C) is moved to the right. The paper is ejected to In parallel with this, the next original (c) is similarly set on the contact glass H from the original tray (b), and its copying operation is performed. When the copy cycle of the last original (G) is completed, the ADF mode display section (G) turns OFF and the ADF mode display section (G) turns off.
) F mode copying is completed.

On the other hand, insert the original (c) through the manual feed slot θQ and press the manual feed slot! If you press the print key ring in the state detected by j[, 5ADF linked copy cycle, that is, 5A
DF (semi-automatic document feed) mode starts. This 5A
When the DF mode is established, the drive motor G → rotates, and after a predetermined timing elapses, the solenoid θ) is activated and the gate pawl Φ is raised in the opening direction, and at the same time, the solenoid θ is activated.
→The roller pair θ scratch grips the document ati and its feeding starts. Then, at a predetermined timing after the leading edge of the document Q passes through the intermediate sensor o'a', it is moved by the inertia of the drive motor 0◆f,r OFF The document (C) is set at a predetermined position on the contact glass (C) by hitting the claws θ.

In addition to these A and DF related modes, copy IN
There are a sorter mode and a double-sided copy mode as standalone modes. First, the sorter mode is set by pressing the sorter mode key O◆, and the transfer paper discharged from the copying machine main body (4) is sent to the sorter mechanism (3), and each bin 0
collated or sorted by force.

On the other hand, the duplex copy mode is set by pressing the duplex mode key Z, and the front side mode and back side mode are alternately repeated every time a copy cycle is started. First, in the front mode, the transfer paper is discharged and stored in the double-sided tray 07). On the other hand, in the back mode, the transfer paper is re-fed from the duplex trays 0 to 10, and after copying is ejected to the paper ejection tray (or the sorter mechanism (3) side).

By the way, the selectively operated reversing mechanism (l:1 digit) is configured as shown in FIG. (71) consists of a front roller Q and a rear roller f, which move on an arc centered on the axis of the wooden main roller) and the main roller). These rollers (73 (7
4 can be engaged with each other by forming a plurality of grooves along the axial direction thereof, and there are a separated state shown by a solid line and a close state shown by a chain line. A curved guide plate (a reversing path (74) is formed by 1'G, and this reversing path fQ is connected to the return roller pair) is provided above. and presser roller G1, presser roller Q■J lever ←)
′? The drive roller (7) is connected to the solenoid (o) via the solenoid (r) and is provided so as to be able to move toward and away from the drive roller (7).

゛Also, between the main roller) and the front roller (/3) there is provided a paper fissure 6 for detecting the entire passage of the trailing edge of the transfer paper, and a photo interpreter ←1 that turns on the solenoid 0υt based on its operation. Furthermore, a guide plate 0◆ is provided from the main roller (7 O) and rear roller H side toward the paper discharge tray (+9. side).

Next, looking at the circuit configuration for the solenoid os that displaces the roller from Q to the state shown by the full solid line, as shown in Figure 6, when the solenoid is θ, it is connected to the transistor q, and in addition, the CPU Yu, ROM (I), R

is connected.

As a result, at the time of reversal, the solenoid (c) is turned on and the roller (13 (7) is displaced to the separated state shown by the full solid line).

As a result, the transfer paper that has been transferred and fixed is transferred to the main roller).
(to the front roller) to reverse the path. When the rear end enters the Q and comes out, the Baber filler ←→ returns and detects this. The heel photo interpreter → closes, so the solenoid eυ is turned on*, and the t roller rough 1 moves as shown by the dashed line. It contacts the drive roller (7→. Therefore, the reversing path (7'
The transfer paper stuck in G is driven by the drive roller → and presser roller, which are constantly rotating in the direction of the arrow. 1, the return force acts [2, from the rear end side to the main roller], and the rear roller grips the rear roller side, and the sheet is reversely discharged. On the other hand, when the roller (c) is not reversed, the roller (c) f remains in the state shown by the dashed line, and the transfer paper passes through as it is.

In order to maintain the correct page order of the original document and the page order of the transfer sheet, the reversing mechanism α1 is controlled according to the flowchart shown in FIG. First, when the ADF mode is set to 5 ADF modes, it is checked whether or not the set number of sheets is "1" on the condition that the sorter mode and double-sided copy mode are not all used. If the number of sheets set is "!", that is, the mode is to obtain some copies from one original, the reversal mode set switch 0I) is turned ON, and as mentioned above, the renoid ■ is ONt, and the reversal mechanism (11 is enabled). As a result, the transfer sheets are sequentially ejected to the paper ejection tray 0rJ with the copy side facing down.
Set number of sheets for several pages or dozens of manuscripts (A)
If you want to make a copy of ``1'', place the original (c) in the paper tray (b) with the first negative side facing down, or manually feed it and perform the copying operation described above. , the transfer paper will be ejected into the paper ejection tray (6) with the copy side facing downward, that is, in page order starting from the first negative number, so it is necessary to change the page order for both the original (c) and the transfer paper. This improves the efficiency of copying work.

In addition, when the double-sided copy mode is selected, the reversing mechanism θ1 is enabled in the front-side mode, and the transfer paper is reversed when passing through the reversing mechanism Q3', and the duplex tray (1
7), the paper is ejected with the copy side facing up. If the sorter mode is also selected during this double-sided copy mode, the reversing mechanism θJ is enabled also during the reverse side mode, and the transfer paper is reversed so that the front side is facing up and the sorter mechanism (
3), the books are stored in each bin (a) in page order with the front side facing downward.

In this embodiment, the activation condition for the reversing mechanism (1, 1) is that the number of sheets set is "1" when the sorter mode and double-sided copy mode are not used.
You may delete the condition as to whether or not.

This is because if the mode is to obtain two copies from one original, the order of the pages will be reversed, but since the ejected transfer paper must be sorted, it is not convenient for the recipient. This is because there is no set number of sheets, so the number of sheets set is only "1" k fft.

As described above, the present invention presets the reversing mechanism to be fully enabled or disabled in each operation mode, so that the operation mode can be set and the necessary Q setting is possible under programming control. A reversing operation is performed, and the transfer paper can be ejected in the same page order as the original, thereby facilitating post-processing of the transfer paper and improving work efficiency.
