Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables continuous copying from a plurality of originals, and the present invention is useful for copying machines and! Microfilm: A sheet document automatic feeding and repeating conveyance device that automatically feeds a sheet document such as a photographic device into the document path and at the same time repeatedly exposes or illuminates it, and if the sheet document is a double-sided document, it automatically reverses its front side. This invention relates to a double-sided repetitive conveyance device that automatically feeds sheet originals and feeds them into an original path.

Copying machines that perform slit exposure while transporting sheet originals generally use a sheet original feeding device that separates stacked sheet originals one by one and automatically and continuously feeds them into the original path. ing. However, since this device continuously exposes stacked sheet documents one by one,
It is convenient to copy sets, i.e. copies of - copies, but when copying several sets, i.e. sheets, one has to copy - sets of originals several times, i.e. The device must be loaded several times, which is inconvenient.

In order to improve the above points, a reversing conveyance device is added to the conventional automatic sheet document feeder, and when copying multiple copies of a set of documents, each document is exposed multiple times and sequentially copied. A device (hereinafter referred to as an auto-repeat feeder) that performs copying and automatically makes multiple copies of a set of originals has already been proposed by the same inventor. (% Gansho 50
(No. 87026) However, when the sheet original is a double-sided original and the front and back sides are to be copied, with KFi and auto repeat feeders, it is necessary to copy only the front side of the set of sheet originals and then reload them to copy the back side. There is.

An object of the present invention is to provide an apparatus (hereinafter referred to as an ``auto-repeat duplex feeder'') in which an auto-repeat feeder is added with a function of automatically reversing the front and back sides of a double-sided document.

KFi copies the front and back sides of a double-sided original, and copies the front and back sides of a single sheet of copying material, so-called double-sided copying. In some cases, the front and back sides are copied onto one side of two sheets of copying material, so that one sheet of original corresponds to two sheets of copying material. The embodiment of the present invention uses an optional copying machine that can be used.

In Section 11ii1, the operation of the copying machine main body constituting one embodiment of the present invention will be explained.

Three originals are placed on the original platen glass 2 constituting the original surface, are pressed by the original pressure plate 2', and are illuminated by illumination lamps 6,
The optical path length is kept equal by the movable reflection mirror 4 that moves together with this movable reflection mirror 4 and the movable reflection mirror 5 that moves in the same direction at a moving speed of H of this movable reflection z2-4, and is further fixed and fixed with the lens 7. The light is subjected to slit exposure through a reflection tube 8.9, and is MIl onto a photosensitive drum Al.

That is, the document 3ti is exposed to slit light while being scanned by the optical system (illumination section) K.

Photosensitive drum! The surface of the photosensitive layer has a transparent edge layer on top of which is highly photosensitive, and is positively charged by a positive charger 11 supplied with a positive high voltage current from a voltage source 1G. Subsequently, when reaching the exposure section 12, the photosensitive surface is exposed by the original horizontal beam and at the same time is subjected to AC charge removal by the AC discharger 13, which is supplied with an AC high voltage current from the high voltage power source IO.

Next, the entire surface is exposed by the entire surface exposure lamp 14 to form a static latent layer on the drum surface (photosensitive surface), and the developing device 1
I'm in 5th.

The current process is carried out using a powder lump using a sleeve method, and is converted into a solid material.

Next, paper is fed from the cassette 16 and sent to the 9th subject 1.
7 is in close contact with the photosensitive drum 1, and the transfer 'WI'#L device 18
sf due to charging by positive high voltage current from island pressure power source lO,
The image on the drum l is transferred onto the copying material 17. The copy material that has been transferred is separated from the photosensitive drum l in a separating section 19,
After being guided to the fixing section 20 and fixed, static electricity removal i! i! 23
Excess charge is removed by the discharge roller 22, and the discharge roller 22 discharges the paper onto the tray 30. During normal copying (single-sided copying), copying is completed, but on the other hand, Dora II! Ei
The remaining toner on the papermaking drum is cleaned by the blade 21 pressed against the li (photosensitive surface) Fi, and the next cycle can be repeated again.

Furthermore, this copying machine can easily copy on both the front and back sides of the copy material. In other words, the copying paper that has undergone front side copying (which corresponds to normal copying) is not ejected from the machine, but is guided again to the transfer device (9th stage for back side copying).

First, regarding the paper conveyance system, the copy #17 that has completed surface copying is transferred to the second paper feeding means 1 by the ejection roller 22.
It is discharged at 50. In the surface copying process, the swinging member 161, which is a part of the paper ejection tray 160 that can swing around the rotating shaft of the ejection roller 22 as shown in the figure, is activated by a solenoid or the like (not shown). It has been pushed up to the position shown by the two-dot chain line. Therefore, the copy paper that has passed through the fixing section 20 and is discharged by the discharge roller 22 is stacked on the second paper feeding means 150.

After a predetermined number of front side copies have been completed, the sheets are loaded on the second paper feeding means 150, and arranged by an alignment means such as the swinging arm 158, and then the back side copying process begins. The copy material 17' loaded on the second paper feeder 9150 is held by the spring 153 with its leading end A abutting against the stopper blade 151Km which is in the operating position. 151 is released, and the copying material 17' is rotated once to feed the copying material 17' in opposite directions.
-154 and a part of the feeding roller constituted by the separation roller 155 slides. Next, feed roller 15
4 and the separation roller 1550 rotation, the paper machine photographic materials are separated and conveyed one by one, transferred into the guide plates 156 and 157, passed through the conveyance roller 28, and are again controlled by the register roller 29, and are readjusted by the paper feed signal. It is discharged at 16G.

In the back side copying process -h, the swinging member 161 returns to the position indicated by the solid line, so that the copy sheets 17' ejected by the ejection roller 22 are stacked on the paper ejection tray 160.

Here, the element shown at 24 prevents the copy material conveyed from the first or second paper feeding means from jamming, and the ejecting roller 2
2 is a jam detection and output element that detects whether or not the paper has been ejected.

In order to avoid complexity, a detailed explanation of the drive system of the copying machine main body and the sea fence of each process will be omitted, but the structure is such that a photoreceptor is formed on the drum ridge and rotates at a constant speed, and each process is arranged around it. , a paper feed drive system that feeds paper in synchronization with the optical system, and a method that drives the illumination section and the reflection mirror 2-5 at a speed of 2:1, etc., are commonly used.

A feature of the present invention is that the above-mentioned document table fixed type copying machine, that is, the optical system moving type copying machine, has an auto-repeat duplex feeder and a car loading surface integrated with the document table including the auto-repeat duplex feeder. Both functions are switched by moving the entire device a certain distance.

Figure 1 (In the case, an auto-repeat duplex feeder is installed at the right end of the document table 31, and the entire document table is moved from the position where the document table fixing method for copying thick originals shown in FIG. 1 is used. a!1 Move the auto-repeat duplex feeder shown in Figure (b) to the position where it will be used. At this time, the illumination section will be moved directly below the document guide glass. Document table 31
11.40, it can be easily moved manually from side to side on a rail 41 fixed to the main body, and can be locked in the above two positions.

Next, the auto-repeat feeder will be explained in relation to the main body of the copying machine.

During a preparation period such as turning on the power switch and performing form-up, the surface of the drum 1, including the characteristics of the photoreceptor, is prepared in a copyable state 11. The main body of the copying machine includes a cam disk (not shown) that rotates at a constant speed at a certain ratio in synchronization with the drum l, and several groups of forces are arranged. A group of microswitches (not shown) corresponding to the cam group is arranged near the cam disk, and a periodic signal is generated during one cycle of the cam disk. One rotation of the cam door plate corresponds to the copying stroke of one copy (-copying cycle), and the stopping position of the cam disk is determined by one of the cams. The main body of the copying machine includes a single-sided copy/double-sided copy switch (not shown) for selecting whether to copy one side or both sides of a sheet original.

In addition, there is a number counter on the main body of the copying machine, which allows you to set the number of copies to be made from the same original, that is, the number of copies to be made from one set of sheet originals. Gives an up signal.

In addition, the paper feed drive system of the copying machine main body receives a paper feed signal from the cam disk, so that one sheet of the copy material 17 at the ah portion is transferred to the paper feed roller 3.
1, and passes through the feed roller 28 while being corrected for skew by the preliminary register roller 32,
A register signal from the cam disk is used by a register-two 29 to align the position with iii on the photosensitive drum l, and the transfer position is reached. In addition, in the case of back side copying, the copy material fed out from the paper feed means 15G of 3112 is controlled by another paper feed signal from the cam disk and a register signal.

First, in the 11th PIIK, auto repeat day.

This section provides an overview of the operation of the plex feeder.

Multiple sheet manuscripts! With the side to be copied facing down, stack the pages in order from the bottom, and place the last page on the loading table 51 with the highest sum. When the number of sheets counter is set and the copy button is pressed, the separation roller 53 and feed p-tooth 52 rotate in opposite directions to feed the original sheet.
rotates, and the stacked top sheet document 50', 1
The last page of the zero document is separated and conveyed continuously by pull-out rollers 54 and 55, and at a standby position, the leading edge of the sheet document is detected by the lamp 41 and the light receiving element 42, and the sheet document is temporarily stopped. When the paper feed signal of the main body is issued by the cam disc which is started every second in response to the copy start signal from the copy button, the repeat drum 66 starts making one revolution in response to the same signal, and when it rotates to a predetermined position, the sheet original 50' is again fed. is conveyed by the drawer 4-2 54, 55 and the feed roller 52, and the sheet document 50'
The tip of the guide glass 4 is held in the gripper 71Fc of the repeat drum 66 in synchronization with the photosensitive drum l.
3 and subjected to slit exposure.

The gripper 71 holding the tip of the sheet handle @SO releases its grip #i when the sheet number counter 1 is set to 1 for single-sided copying and when the repeat drum 66 further rotates to a predetermined position. Then, the leading edge of the sheet original 50' is pushed toward the guide plate 72, and the sheet original 50' passes through the ejection rollers 73 and 74 and is ejected to the original tray 'J2 in a U-turn pattern. At this time, the grip is released, and the sheet document 50' is fed by the presser foot 45.46. The conveyance interruption of the pull-out rollers 54 and 550 is larger than that of the four-to-two 52, and the second paper is continuously separated and fed by the separating and feeding reels 12 and 53.
A 0rtJK gap is created between the leading edge of the gi-th original sheet and the rear end of the gi-th sheet original 56. Due to this gap, the second original is distinguished from the first, temporarily stopped, and then sent out again under control in conjunction with the repeat drum 66. A single-sided copy of a tilted sheet is required from one original! If a plurality of sheet number counters are set, the leading edge of the slit-exposed sheet 'original' will be attached to the grip 71K of the repeat drum 66. , 135, and is again subjected to slit exposure at the guide glass 38.

The original that has been exposed the same number of times as the number of copies required is transferred to the grip 710 (of the repeat drum 66) as described above.
The document is released from the original document tray 92 and is discharged to the document tray 92.

At that time, the @2nd sheet original is detected by the lamp 41 and the light receiving element 42, and the document is temporarily stopped and waited for 9 minutes.
The first draft of the t-th sheet is removed from the grip 71, the repeat drum 66 is rotated to a predetermined position, and then conveyed.

The above is the same as the auto repeat feeder.

If the number of sheets counter is set to 1 and one double-sided copy of one set of sheet originals is required, the stacking table 5! It is necessary to copy the front side and the back side of a sheet original by stacking the pages in order from the bottom with the bottom side as the front side. The tip of a sheet original whose front surface is slit-exposed in the same way as single-sided copying. Libby Sidram 6

After being fed for 7tC and transported to the stocker 129IC, when the trailing edge of the sheet document is detected by the lamp 13G and the light receiving element 131, the depressure rollers 126 and 127 are temporarily stopped. The repeat drum 66 rotates from the first rotation, and when the repeat drum A 66 rotates to a predetermined position, the depressure plate x row 9-126, 127 starts rotating in the opposite direction to the previous rotation, and the sheet original 50 is conveyed in the direction of the repeat drum 66. Only then will the backside copying process begin. The leading edge of the sheet original 50'' (corresponding to the rear 111 in the front side copying process) is placed by a gripper 71tC, and the back side is subjected to slit exposure in synchronization with the photosensitive drum 1.

The operation of reversing the sheet document will hereinafter be referred to as the reversing operation of the sheet original.

The leading edge of the sheet original 50'0 exposed to the slit passes under the gripper 711C (the guide plate again) 2, and the sheet original is turned over again by the depress rollers 126 and 127. Then, it is released from the grip of the gripper 71 and is ejected to the document tray 92. At this time, the second sheet document is detected by the lamp 41 and the light receiving element 42, and after it has stopped for a while, it waits.
The first (Z+) original is removed from the gripper 71, the repeat drum 66 is rotated to a predetermined position, and then conveyed. Thus, the repeat drum 66 stops at the home position when the next sheet of original is not waiting. /) If several double-sided copies are required from each sheet original and multiple sheet counters are set, use the gripper 71K (as expected) in the same way as for single-sided copying of sheet originals. The surface is slit-exposed the same number of times as the number of copies required, passes under the guide plate 720 again, and is moved to the de-plex roller 126.
At 127, the sheet original is turned over, and the back side copying step kII begins. Similarly, in the back side copying process, when the slit exposure is completed the same number of times as the number of copies required, the sheet passes under the guide plate 72, and after the sheet original is turned over again, it is released from the gripper 71. It passes through the discharge row 9-73 and 74 and is discharged to the tray 92tC. The plurality of sheet originals stored in the ejected tray 92 are stored without changing the page order when set on the stacking table 51.

In addition, the KO-Sea chain 120 transmits the rotation of the sprocket 12LK and rotates the discharge coolers 74 and 73. The repeat drum 66 rotates once, the cam 69 presses the micro switch Mal, and outputs a document start signal.The sheet document is again conveyed by the drawer four-sheets 5-4 degrees and 55 and the sand feeder four-two 52. be done. Immediately before the leading edge of the sheet original hits the repeat driver ^66, the gripper 71 rotates open under the action of the sector gear 78 and the convex portion 117 of the cam plate 85, and closes after the leading edge of the sheet original contacts securely. (Figure 115). ,,,.

The repeat drum 66 holding the sheet document in its gripper 71 rotates in synchronization with the photosensitive drum 1, and further rotates while performing slit exposure of 111 on the guide glass 43. M8

The document passes through 73 and 74 and is discharged onto the document tray 92. The repeat drum 66 #i rotates further, the gripper 71 closes, and when the next sheet document is waiting, the cycle is repeated. When the next sheet document is not waiting, the home position cam 119 presses the micro switch M83 and the repeat drum 66 stops. do. Next, when the count-up signal is not coming from the copying machine main body, that is, when multiple copies of the set of documents are to be copied, when the cam 70 presses the microphone switch M82, the plunger 8Ll is energized and activated, and the lever The cam plate 85 is connected to the cam plate 85 via 86 in FIG.
It moves to the position O indicated by the dotted line in the figure, and the fan-shaped gear 78 no longer operates.

Therefore, the gripper 71 passes under the guide plate γ2 and returns to the glass 43 while holding the leading edge of the sheet document in its mouth.
Slit exposure is performed at The sheet count force "ranter outputs a count up signal indicating that the required number of sheets has been reached, and when the force ^70 presses the micro switch M82, the power to the plunger 8L1 is cut off and the cam plate 85 is turned off. Due to the return force of the spring 89, the shaft 68 slides in the axial direction and returns to the range where it acts on the sector gear 78.Force +, the 9 part 1111 of 85 pushes up the sector gear 78, opens the gripper 71, and Push the tip of the document toward the guide plate γ2 and eject the sheet document to the ejection roller 73.

The above is an explanation of the operation similar to that of an auto-repeat feeder, that is, one-sided copying of a draft sheet. Next, if one set of double-sided copies of the sheet original is required, switch the changeover switch on the main body from one-sided copy to double-sided copy and set the number of copies counter to IKl. During double-sided copying, a count-up signal is issued from the main body of the copying machine in the front side copying process, and when the cam 70 presses the micro switch M82, the plunger 8L1 is energized and the cam plate 8 is activated via the operating lever 86.

The cam 140 is at the same angular position as the home position cam 119! When the microswitch M84 is pressed, the current to the plunger 8L1 is cut off, and the cam @aS slides in the axial direction of the shaft 68 by the restoring force of the spring 89 and returns to the position where the sector gear 78 acts.

The Tx--Tx 126° 127 is reversed and the sheet original 50' is started to be fed from the stocker 129 toward the repeat drum 666.

The repeat drum 66 continues to rotate, and the protrusion 136 of the cam plate 85 pushes up the fan-shaped gear 78 to open the ripper 71. When it reaches the protrusion 137, the gripper 71 begins to close, and after passing the protrusion 11137, the sheet document 50 ' is fully anticipated. After that, Tasochi Cam 69 mic four switch M
When 81 is pressed, plunger 8L1a is overcharged and cam plate 85
moves again to a position where the fan-shaped gear 78 does not operate. That is, the sheet original is turned over and the process moves to the back side copying process. Similar to the surface copying process, the sheet original 50 is gripped by a gripper.
While the tip is held in 71, the back side is exposed to slit light on the guide glass 43. When a count-up signal is emitted from the copying machine during the backside copying process, a force of 7G is generated.
-Press #M82, the ton plunger 8Lt continues to be energized, and the leading edge of the sheet original 50' passes under the guide plate 720,
When the force 14G pushes Mg2, the plunger 8L1 is de-energized, the force plate 8s returns to its original position by the return force of the spring 89, and the original sheet is turned over as before. .

When the cam 69 pushes MB2, the plunger 8L1 is energized again, and the force ^ [8B moves to the position where the fan-shaped gear 7$ does not operate, and grips the tip of the sheet document s-o' and the gripper γ.

At that time, the second sheet original is placed at the lamp 41 in the same way as for single-sided copying. and the light receiving element 42 detects that the original is green, *
It is removed from YZ and discharged onto the tray 92. The repeat driver 66 is rotated to a predetermined rotation and conveyed from the gate.

In the case of double-sided copying, the count-up signal comes from the copying machine itself, and once every 1 to 2 minutes, the process of turning the document over and making it yourself consists of multiple steps! In the case of a set of sheet originals, this is to match the page order of the sheet originals stacked on the stacking table 51 and the thickness of the page layer that is ejected after copying and stored in the tray 92.

In order to avoid complexity, I have omitted the explanation of the copying process of the copying machine itself during double-sided copying, but in front copying, the copying material 17 sent out from the cassette 16 passes through the front copying process. No. 2 paper feeding means 15 OK is ejected and stacked.

Subsequently, in the back side copying process, the Fi copy material 17 is sent out from the second paper feeding means 15G, passes through the back side copying process, and is transferred to the tray 160.

This is an explanation of the paper-shaping operation in which the leading edge of the sheet is gripped and released, and the operation of turning over a sheet original using the depressing machine 4-2 126 and 127FC. The gripper 71 has springs 1171' at several locations in the longitudinal direction.
, as shown in FIG.
Lead to the top of 135.

Guide board 72 and De Apres, Tutas guide board 132°13
5 has several cutout grooves 72' at corresponding positions so that the raised portion 71' can pass through.

In addition, as mentioned above, by making the part of the gripper that holds the sheet document thin with a transparent member as necessary, it is possible to copy the entire surface of the sheet document.
Figure 12φ) Based on the circuit diagram, Kl! I will clarify.

In the 11th g time chart, ■ becomes H level due to the copy start signal of the main unit, and during the copy period, this repeat 4
This signal holds the level 1 and returns to L level upon completion of copying. 2 is a signal to indicate whether or not it is double-sided copying, and in the case of double-sided copying, it is set to H level for a predetermined period of time by a changeover switch. ■ becomes a KL trell when the power switch is turned on, and becomes H for a short time depending on the paper feed signal of the main unit.
This is a pulse signal that reaches the level.

3 is a signal indicating that the required number of copies has been completed by the number of copies set by the number of copies counter, and the signal changes from the L level to the H level to produce the above-mentioned display.

The above ■ ~ 0 are the signals supplied from the copying machine main body to the repeat deaplex feeder side. ・In addition, during double-sided copying, the paper feed signal of the main body is controlled by the 1 paper feed stop signal, which will be explained later. The paper feeding operation is
controlled not to do so. ■ is repeat drum 66
cam 11 with a signal indicating whether or not it is at the home position.
With G! Ikuta switch M8: Made from IC. When the repeat drum 66 is at the home position, the level is L. Otherwise, the level is H.

As mentioned above, the repeat drum 66 is started from the home position (normal stop position) by the paper feed signal from the main body, but this is because the copying material 17 is started, the sheet original is conveyed, exposed, and then the copy material 17 is fed. This is because the time it takes for my tip to reach the transfer position is almost the same composition sum. Strictly speaking, the path is such that the copying material 17 can reach it in a slightly shorter time, but since there is a possibility that it will be delayed due to slipping, etc., the tip should be stopped in advance and the loop formed when it reaches the register roller 29. copy material 1 by the register signal from the cam disk.
7 is restarted and the tip of the tip matches the tip of mine.

Therefore, if a configuration other than this embodiment is adopted, the repeat drum 66 can be controlled by a signal other than the paper feed signal (for example, a signal is issued for this purpose from the cam disk), and it is necessary to do so. There is. (2) is a signal for taking a tie-off to restart the sheet original from the standby position, and is configured by the cam 69 and the microswitch M81 so that the timing KH is at the level that should normally be started at the L level. ■ is a signal for moving the cam plate 85 that controls opening and closing of the gripper, and the cam 70! This is obtained from the current μ switch M82. ■ is lamp 41
and a light receiving element 42, a resistor and an operational amplifier 5
A signal obtained from 50 is a signal for determining whether or not the sheet original is in the standby position.
This is a signal that becomes H level when i is in between. As in ■, the signal obtained by the lamp 13G, the light receiving element 131, the resistor, and the operational amplifier detects the presence or absence of a seed original in the stocker, and becomes an L level when there is a sheet original, and an H level when there is no sheet original. It is. 0 is a signal obtained by the microswitch M84 and the cam plate 140 for controlling the gripper.

The above ■~[phase] are the signals obtained on the auto repeat deaplex feeder side, and by appropriately combining these signals using means of logic circuits, the repeat drum 66, drawer gate - two 54.55. cam 85
Controls the operation of the deaplex Ie1-4-126, 127°.

An example of a different circuit for this purpose is shown in FIG.

In addition, as means for obtaining these signals, a cam plate, a microswitch, a lamp, a light receiving element, etc. were left behind in ζ, but in addition to these means, 1 permanent magnet, a Hall element, 1 light emitting diode, a light receiving semiconductor, an ultrasonic wave Various methods can be used, such as combinations of oscillators and receivers.

Next, the operation of the Kll path will be explained with reference to the time chart in Figure 11.

After the power switch (not shown) is turned on, the power-on reset circuit is used to clear the respective triggers within a short period of time.

Next, if the repeat drum 66 is not in the home position, turn on the CLI and apply the drive motor's power to the repeat drum 88 until the signal ■ goes to L level. Place it in the home position,
Put the auto repeat deaplex feeder on standby. After the form-up period of the copying machine is completed, a sheet original is set and the copy button is pressed, the signal ■ will be activated.
Since it is at H level, the drawer is drawn through C'L2.
C54. ! $5 and the feed roller 52 are driven, the sheet original is guided between the lamp 41 and the light receiving element 42, and the signal ■ is sent to L.
Operate until the level is reached and place the sheet original in the correct position.

In the following explanation, for the sake of brevity, a detailed circuit explanation of the main body of the copying machine that operates using conventionally known means and methods will be omitted. The following is an example of a case where two double-sided copies are to be obtained. Since it is a double-sided copy, the second signal (■) goes to the KM level at the same time when the copy button is pressed.

Paper feed signal of the copying machine main body (C
Turn on the LI, rotate the repeat drum 66, and repeat drum gear 6 attached to the repeat drum 66Kml.
The cam on 4 operates the microphone 4 switch Mal-M84.

For repeat drum home positioning! Orgasm switch M
83 is restored and the signal (2) becomes H level. From then on, 1 L level pulses are obtained for each rotation of the repeat drum. Next, the original start microswitch M81, which feeds the original in synchronization with the repeat drum, is operated by the force plate and supplies one H level pulse per drum rotation. This signal ■ turns on CLZ and pulls out the rollers 54, 551-
However, if you want to obtain multiple copies of one original, you must make sure that drawer 1 and 2 do not operate with this signal during this period. No. When the first original is sent out by the sender-two 52, the second original is then automatically sent out by the rotation of the sender-2-520. L2 is the first original feeding cylinder 1 and the second
Due to the speed difference between the originals, the light receiving element 22 receives light and the signal 7 becomes H level, so the operation continues until this signal becomes L level, and the second original is placed in standby mode.

Next (as the repeat drum rotates, the gripper microswitch M82 operates, and similarly to the above signal, it supplies a pulse signal ■ of 1 OL level per repeat drum rotation. This signal opens and closes the gripper. In other words, this signal operates the cam plate solenoid 8L1 to prevent the gripper from opening.

After performing slit exposure by rotating the repeat drum holding the original in its gripper and creating one bee for two sheets, the count-up signal from the copying machine and the signal obtained from the first MB2 after this signal. Yosho, Cam 11
moves to the point where the gripper is opened and sends the original to the stocker. This completes the process of copying the surface of the first original. It is possible to determine whether the process is a front-side copying process or a back-side copying process based on whether the output Q of the Tsuritsubu flop circuit to which the force from the copying machine main body and the runt-up signal are added is at L level or H level.

The deaplex roller includes a lamp 130 and a light receiving element 1.
When the photoswitch B constituted by 31 is detected, it rotates in the forward direction Ka, and when this 7-point switch B receives light, it stops the forward rotation and stands by.

While waiting at the start, this roller starts reversing in response to a signal received from MB2 and sends the original from the stacker to the repeat drum. The four-two reversal stops when the original is sent out and the photoswitch B receives light.

During this time, the repeat drum ^ rotates once and then enters the backside copying machine 11 with the original sent out from the stripper in its mouth.

The cam plate moves toward closing the gripper by the signal obtained from MB2. After performing 2WA slit exposure in the same way as in the surface copying process, the gripper opens at the first MB2 signal after the count-up signal from the copying machine and transfers the original to the stocker. The operation is similar to that described above.

In ζζ, once the original is sent to Stotzker,
This is to align the front and back sides of the original when copying is complete. The original sent from the stocker to the repeat drum that has rotated once is gripped by a cam [K] that moves to close the gripper in response to the MB2 signal, and immediately after that, the MB2 signal opens the gripper and the back side is copied. Eject the completed original to the tray. This completes the process of copying the front and back sides of the first original, but the paper feed in the main unit must be stopped while the original is being fed into the stocker. It is necessary to combine the signals from (1) to [phase] appropriately to send a paper feed stop signal to the main body of the paper making machine to stop the paper feed for a period of time.

The explanation of the control for sending the copying material that has been copied on both sides of II into the main body again for copying the back side will be omitted, but if the control is performed based on the count-up signal obtained on the main body side, jL Just note that %/-h.

The second original is stocked with the first original★
After being ejected to the tray via MS1ll:, it is fed by the signal obtained from S1ll and is ejected to the tray by repeating exactly the same operation as the original. After ejection, the repeat drum is stopped at the home positive S/con by returning the copy signal (2) from the main body to the L level (the signal obtained from MB2 is at the L level) and all copying processes are completed.

As explained above, the control signal for controlling the mechanical system is expressed as KgllllK together with the detection signal. In other words, if the signal of Repeaty F Drum Co., Ltd. does not rotate during the H level period, it will not appear.
During the H level period of the signal II&, gripper use
It must not operate during the H level period of the i [phase] signal. Further, the fz-pvx4-two must rotate forward during the H level period of the signal Qf) and reverse during the H level period of [phase]. Furthermore, during the H level period of signals 23 and 40, paper feeding of the main body is not stopped, which is 1%/%.

Although the drawer 4-2 continues to rotate until the end of the final original sending 41:ybee, there is no adverse effect on the copying operation. A typical circuit example for creating these signals is shown in FIG.

When the signal (2) from the photoswitch B is applied to the inverter 501, the output becomes a good one by inverting the polarity of (2), and when this is added to the click input of the 7-rig, 7-4, 502, the Q output becomes the signal [phase]. When the signal [phase] and the signal ■ which is the inverted polarity of the signal 0 are added to the anti-game) 503, the output signal [phase] and the signal on table Lj are in the H level, and the despealer 4 is rotated in the normal direction. I have to let it happen. That is,
For this reason, the preset four-two rotates in the normal direction during the period when the photoswitch B is first illuminated. When the photo switch B receives the changed light again, the o-two stops normal rotation and enters the standby state @#C. The Denny Pretsuta low-two starts reversing in response to a signal from MB2 obtained during standby, and continues reversing until photoswitch B receives light again. That is, 7
The q output [phase] of the Lip 7 quad 502, the signal ■ of the Foshiswitch B, and the M840 signal [phase] are connected to each other) 504
In addition to the output signal [phase] at 9, the flip-flop
06, and the output signal of the AND gate 505 to which the photoswitch B signal ■ and the photoswitch AO signal ■ are added as input is the reset signal of the 7-lip 70-tube 506, then this 7-lip 7p tube 506 Q
The output is a signal [phase], and if the depressor p-2 is reversed only during the period of this signal oOH level, a desired MO operation can be performed.

As mentioned earlier, in the case of double-sided copying, it is necessary to stop paper feeding on the main body side at a certain timing, and mtR is performed at i in response to this paper feeding stop signal.

79 Tsug 7a Tsug s 1sfJQtB Power signal #j is the count up signal ■ to the set input and M to the reset input.
It is obtained by adding the original start signal 0 obtained from Bl. 7 rip the count up signal 7
When added to the human power, the Q output signal becomes the signal @, and the 4 output becomes the signal [phase]. Signal @ and de gourd-
Prettas 4-2 reverse drive signal @ AND gate 5
17 is added to the output signal [phase] and the signal @ is added to the OR gate 5180 input to obtain the output signal .

On the other hand, the output signal of Nashi Dogut 521, which is input with the signal [phase] and the photo switch person's signal ■, is [phase]
becomes. The output of the AND gate 525 to which the signal ■ and the signal [phase] are input becomes the signal @. If the ζ0@ number sets the Aritub 70 and the Tube 527 and resets it with the signal ■ obtained from M8'2, the Q output becomes the signal [phase]. The Q output of the 7-rip 70-tub 527 and the signal O are added to the λ force, and the output signal of the AND GOUT 528 is added to the reset input of the 7-rip 7-o knob 535, and the #i signal [stock] is added to the set input. When the Q output signal O of the 7-rip 7-four 535 and the signal 2 are added to the AND gate 523, the output becomes the signal [phase]. The signal [phase] and the signal [phase] are added to the AND gate 522 to obtain the output signal [phase], which is added to the OR gate 519 together with the signal [phase]. The output signal of 519 satisfies the condition O. ②If the count-up signal from the main body is obtained, then the paper feed signal issued from the main body is stopped tfgl.

■After copying the back side, the paper feed signal after the count-up signal is stopped twice in succession.

■The repeat drum stops the post-rotation neutralization paper feed signal after the bi-operation is completed.

■ is set by the count-up signal and reset by the original start signal. @ is the stocker's original, de-plex 4-2 is reversed, and sends the 7-rip 7-4 Q output signal to the 9-beat drum. ■ indicates that the back side copying has ended and the photoswitch is receiving light (indicates that there is no original). It is possible to realize this using a signal obtained using Or gate! ! 1
It is sufficient to add the 90 output to the AND gate 520 together with the signal ■ and stop the paper feeding of the main body while the output signal is at H level. The operation of the cam plate becomes erratic because the AND signal is taken only when the paper feed stop is for double-sided copying.

Since it is a double-sided copy, in the case of front side copying, the signal obtained at the beginning of MB2 is used to move to the closing side, and the M
With the signal B2, it returns to the open side and sends the original to the stocker. With the cam plate Fi open, the repeat drum rotates 1a, and in order to pick up the original sent from the stocker for back side copying, the decoder plex i- During the two-way reversal and during the back side copy process, the MS1 original start signal moves to the close side and performs back side copying. At the signal from MB2 after the count-up signal indicating the end of copying the back side, the cam plate is returned to the open side and the original is sent to the stocker. After about one rotation of the repeat drum, the force plate moves to the closing side due to the original start signal while the duplex 4-2 is being reversed, and the original from the stocker is held in the gripper and conveyed, and the signal from MB2 is sent to the close side. Go back and eject the original into the tray.

Force A1 during copying work on the second and subsequent originals
The operation of fL is exactly the same as for the first original described above.

In order to make the force board perform such an operation, we can consider the circuit example described below.

Add the Q output signal [phase] of the 7 lip 70 tube 516 and the above-mentioned signal @ to the AND gate 526 to obtain the output signal [phase],
Add to ORGATE 531. Signal■ and photo switch B
The signal O is added to an AND gate 529 to obtain an output signal [phase] which is applied to an AND gate 530 together with an output signal [phase] of a seven-lip flop 535. The output signal of the AND gate 530 becomes a signal [phase] and is applied to the OR gate 531.

The Q output signal O of the Aritz flop 515 and the signal [share] of MB2 are added to the AND GO) 524 to obtain the output signal [phase].

If the output signal of the OR gate 531 is selected as the set input of the flip 7 flop 532 and the signal [phase] is selected as the reset input, the output signal of the flip flop 532 becomes the signal @. This and the q output signal [phase] of the ARITUB flop 527 are added to the OR gate 533, and the output is applied to the AND gate 534, where the signal ■ and the AND signal are combined.
Output @ is obtained through 45. The reason for taking an AND with the signal ■ is the same as in the case of paper feeding stop.

(Oagoo) to 545: The output signal @ which will be described later is H
By moving the cam plate to the closed side during the level period, the darper can be made to perform the desired operation.

The sender 1-2 starts rotating at the same time as Copy Star F, and when the photo switch is activated, it pauses and waits. Next, it rotates again with the original start signal of KM8t and sends out the original. After the first original is sent out, the focus switch receives light again, so p-
Two continues to rotate and stops and waits when the photoswitch person is illuminated again. The roller sends out the second original when the deaplex roller is not rotating in the normal direction and when the cam plate is on the open side, the original start signal is received.

The above conditions can be realized as follows.

Duplex roller forward rotation signal■ and cam plate signal @Noagu)50? I! c and get the output signal [shares]. Flippu pg 511t) Q output [
The output signal [phase] is added to the AND gate 508 together with the polarization part i and the signal ■, and the output signal [phase] is set as the set input of the flip-flop 509. In addition, the signal ■ is added as a reset input, and the resulting output [phase] and the output [phase] of the AND gate 514, which is the addition of the signals ■ and ■, are added to the OR gate 51O, and the above operation is performed only once when both sides = pi. If the 9th acid gate 536 performs an AND with the 11' signal 2, and then passes it through the OR gate 537, the signal @ is obtained, and it is only necessary to drive the 12 signal during the H level period of this signal.

The OR gate 537 will be described later.

After turning on the bar switch, if the drum is not at the home position '7M7, the repeat drum will make one turn and pause until it reaches the home position. After the copy l button is pressed, the machine starts the machine with the paper feed signal obtained from the main body, and after all the copies are completed and the original is put out on the tray, it continues to rotate until it returns to the home position.

This is the output signal [phase] of ANDGOO) 512 which inputs signals
By adding phase] to the output signal 513, it is possible to rotate the repeat drum during the H level period of the output signal.

By driving the repeat drum delivery roller cam plate, depressor (2) forward, and vice versa only during the period when the signals (2) to (@) are at H level, these objects can be made to perform the desired operations.

Driving Method Co., Ltd. It is possible to employ a conventionally known method for rounding, but the description thereof will be omitted here for the sake of brevity.

This concludes the explanation of the specific example of double-sided copying. The operation when there are no multiple originals is the same as when there are multiple originals, so the explanation will be omitted. When using this auto-repeat device - plex feeder to make single-sided copies instead of double-sided copies, in other words, to operate as an auto-repeat feeder, the operation must be slightly different from the one described above. -0 The case of single-sided copying will be explained below.

The des-plex low two does not rotate in either forward or reverse direction because the F)X switch B is illuminated and exposed. In the case of single-sided copying, it is not necessary to stop the paper feed at a certain feeder, but it is sufficient to feed the paper continuously (this is because the paper feed stop signal is ANDed with the signal ■ at the AND gate 520). Therefore, in the case of one-sided copying, it is always at the L level (because ■ is always at the L level in the case of one-sided copying), paper feeding is not stopped.

After the repeat drum Fi beep button is pressed, the machine starts one turn at the first paper feed signal, returns to the end of the copy home position, and stops. This is true.

Power ＾ Board is M! It moves to the close side at the signal 52, returns to the open side at the count up signal, and operates to eject the original onto the tray. H level period of Q output of clip 7 quadruple 543 with signal ■ as set input and signal ■ as reset input 1. If the cam 1 is moved to the closed side, the above conditions can be satisfied.

Since the Q output of the flip-flop 543 drives the cam plate only in the case of single-image copying, the AND gate 544 inverts the -double-sided copy signal ■ and returns the good signal ■.
Take the AND and use the AND gate 54 only when copying one side at a time.
During double-sided copying, the output signal from the AND gate 544 is at L level, and the output signal from the AND gate 534 drives the cam plate through the OR gate 545. At one time, the output signal from the AND gate 534 is at L level.

The OR gate 545 adds these double-sided and single-sided cam plate drive signals. The sending and exiting μm two is (1) during the copy period, the period when the photoswitch person is receiving light, (2) the period until the copy methane is pressed and the photoswitch person is shielded from light, (3) the cam plate is on the open side. It is set by the first digital start signal during a certain period of i, and is reset at 9 points when the photoswitch receives light.It is only necessary to drive the on-period of the tree 7 for 3 periods.

The following specific examples can be considered to satisfy the condition -4. Add the signal ■ and the signal ■ to the input, and add the output signal [phase] of 9 and goo) 514 to the OR gate 541. Add the original start signal ■ and the Q output (gripper cam open side period) of the tritub flop 543 to the AND gate 539, set the 7-rip hoop 54G with the output signal, reset it with the signal [phase], and send the Q output signal to the OR gate 541. If added, the output signal satisfies the above conditions.

The output signal of 541 is ANDed with the signal ■ by the AND gate 542, and added to 537.
This is because the output signal from the AND gate s36 is a signal for double-sided copying, and the output signal from the AND gate 542 is a signal for single-sided copying, similar to the Kojiki power board. .

This concludes the explanation of the operation in the case of one-sided copying.

Regardless of whether the original or sentence be singular or plural,
The above operation may be performed.

That's all, repeat drums, drawer adventures.

Although an example of rounding that causes the cam plate deaplex field-two to perform a desired operation has been described, it can be realized in various ways without being set to 0flK.

The start of sheet document feeding on the auto-repeat feeder side is controlled through a single-rotation cam plate connected to the repeat drum, which is controlled by the feed-low signal from the copying machine main body, while the circumferential speed of the repeat drum is Photosensitive drum of the copying machine body
Since the circumferential speed is the same as the circumferential speed of the repeat drum, it is necessary to appropriately design the outer diameter of the repeat drum and the tie that presses the microswitch. Therefore, it is necessary to temporarily stop the repeat drum in accordance with the copying cycle of the main unit. It is possible to eliminate it.
