Abstract

PURPOSE:To prevent the copy material lifting together with the pin and the tip of copy material from loosening when the punch pin is removed by constructing a recording paper processor so that a punch pin enters into a punch guide almost to the tip portion thereof. CONSTITUTION:Punch pins 56a, 56b extending from the lower ends of rolling chips 55a, 55b are received by pin guides 52a, 52b integral with a holder 52, then the punch pins 56a, 56b are moved up and down through rotation of a motor M6 and inserted/removed into/from dies 55e, 55f integrated with a horizontal table 55c so as to punch a paper chip mounted on the horizontal table 55c which constitutes a portion of the holder 52. Since the punch pins 56a, 56b have their tips diving into the pin guides 52a, 52b at positions slightly lower than the uppermost position, punched paper chip can be removed reliably from the pins.

Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a recording paper processing device suitable for use in combination with a recording device such as a copying device. (Background of the Invention) Recently, in addition to conventional copying machines, recording devices such as printers and facsimiles have been widely used in various fields.
Copying machines, in particular, are becoming faster and more multi-functional. On the other hand, when creating conference materials, flIr5 river materials, etc. from materials recorded by a recording device such as a copying machine, it is necessary to arrange, fold, punch holes, or bind the materials after recording, and these processes are necessary. The idea is to improve the efficiency of the total copying process by automating the process, including a sorter for sorting multiple items, an automatic punching device, an automatic paper folding machine, an automatic collating machine, or a combination of these. Some processing devices have been proposed (for example, Japanese Patent Laid-Open No. 61-94180, Japanese Patent Laid-Open No. 61-846).
No. 62, Electrophotography Society Journal Vol. 24, No. 34 (1985)
(pp. 188-194). Tokorote-・Ren no Ki Q Things are usually bound with staples,
Conventionally, there has been no proposed processing device that can punch holes and staple documents at the same time, since they are often used and stored by binding them into files or storing them. Therefore, the present inventors proposed a patent application entitled "Recording Paper Processing Apparatus" filed January 231'l, 1985, in which an intermediate holding part holds a set of recording papers fed one by one from the outside in the order in which they are supplied. a processing unit that performs selective bunching or binding processing on a set of recording sheets held in the intermediate holding section at the holding position; and a storage section that stores the processed recording sheets;
A first conveyance means for conveying unprocessed recording paper to the intermediate holding section, and a second conveyance means for conveying the processed recording paper to the storage section.
We have proposed a recording paper processing device consisting of a conveying means. If this processing device is used in combination with a recording device such as an electrophotographic copying device, it will automatically punch or bind the recorded materials to create conference materials, distribution materials, etc. It's convenient. However, in this type of processing equipment, multiple copies are punched at once using the punch bin of a single-bunch machine, so when the punch bin is pulled out, the copies come out along with the punch pin, resulting in the copy being damaged. The edges of objects become easily disturbed. If you punch the copied material, it is not always necessary to perform image processing. Composition) Unreleased 1!11 was made with the above points in mind,
In a recording paper processing device that automates the punching and binding operations of recording paper, when the punch bin is removed during punching, the copy is prevented from falling into the bin and the leading edge of the copy is disturbed. When you pull out the punch bin to make a single punch, the tip of the punch bin will be almost at the tip or the bunch guy l-
It was designed to go inside. (Example) The present invention will be described below based on the drawings. The processing device to be exemplified next is a copy paper processing device used in combination with a copying device, and No. 11. As schematically shown at M, the copy paper processing unit 5ffl is used by being connected to the copying unit 712 at the position indicated by the broken line E. Before explaining the copy paper processing apparatus l, which is the object of the unreleased copy 1η, the copying apparatus 2 will be explained in the cylinder I'i. Applicable to the present invention 1 A glossy copy paper processing device copies a copy document consisting of a plurality of sheets (for example, 5 sheets from page 1 to page 5 of 117) to obtain at least one copy, and Since it is used for punching and binding, it is necessary for the copying machine to be equipped with a machine that can repeatedly copy multiple copies of originals in sequence, and as a device for this purpose, a circulation type is used. A type automatic document feeder (hereinafter referred to as an RDF device) is used. As can be seen from FIG. 1, the copying apparatus 2 is equipped with an RDF device 3 at the rear, and the RDF device 3 feeds copies D one by one. Copying device 2 and RDF
The general structure of the device 3 and the machine 71 are well known and will be briefly described. The RDF device 3 is installed on the L of the glass plate 10 provided on the top surface of the copying device 2, and as shown in FIG. Place the pages facing each other in the order of 1st page, 2nd page, etc. from the top. ! It is detected by the document placement sensor 1 (S) that the +7 document G has been placed on the document placement plate 111-.At this point, the copy button placed on the operation panel of the copying device 2 is pressed. Then, the rear end regulating plate 12 of the RDF device 3 moves forward, and the entire document G is pushed out in the +i? After passing through the gate 13 and proceeding a little further, when the leading edge of the original is detected by the leading edge detection sensor R32, the trailing edge regulating plate 12 stops L: l-r, the gate 13 lowers by one step, and the trailing edge regulating plate I2 At this point, the copying device 2 sends the original at a predetermined timing.
When 'j' is output, the half-moon-shaped feed-out port roller 14 rotates once, and the second roller 15 rotates to feed out the lowest document one sheet at a time. The sent out document advances along the guide plate 16, is sent by the feed roller I7, its leading edge is detected by the timing sensor R5, and is taken over by the conveyor belt 18 to move the glass plate of the copying device 2 at a predetermined speed. Moving. An optical system 19 consisting of a lamp for irradiating the original, a reflecting mirror, etc. is provided below the glass plate In, and the original is exposed to light while being moved by this optical system 19. A document leading edge detection signal is sent to the copying machine 2 by the timing sensor R3. Then, feeding of the transfer paper starts in the copy unit 2. The exposed original is detected by the paper ejection sensor R8, and transferred to another conveyor belt 20.
, and is placed on L of the remaining originals placed on the original placing plate 11-2. The final discharge of the document is detected by a circulation discharge sensor R85. A jam during document feeding can be detected by the detection timing of the timing sensor R33 and the paper discharge sensor R54. The feeding of the second original 11 starts when the trailing edge of the first original is detected by the timing sensor ns:l. In the same manner as before, when the optical system of the copying device finishes exposing the 3-page, 4-page, etc. originals, the document leading edge detection sensor R82 confirms that the number of originals is 0, and then the copying process begins. Feed one part of the document. If a plurality of copies (for example, 5 copies) are to be made, the original is automatically fed sequentially from the last page [1] and exposed sequentially up to the first page. This document feeding operation is repeated for the required number of copies. In synchronization with the above operation of the RDF device 3, the following electrophotographic process is performed within the copying device 2. When an original passing through the glass plate 107 of the copying device 2 at a constant speed is exposed to light by the optical system 19, the reflected light from the original passes through the mirror 20, lens 21, and mirror 22 to the photoreceptor 23.
Projected to 1-. Since the surface of the photoreceptor 23 is uniformly charged by the charging device 24, an electrostatic latent image is formed when reflected light from the original is projected onto the surface of the photoreceptor 23. The electrostatic latent image is developed into a visible image by the developing device 25, and is transferred onto transfer paper ph fed from either paper feed set 2 [i, 27] in synchronization with the automatic document feeding operation. The image is transferred by the device 28. The transfer paper on which the visible image has been transferred is transferred to the photoreceptor 2 by a separating device.
3, is conveyed by a conveyor belt 29, is fixed by a fixing device 30, and is discharged from the apparatus by a discharge roller 31. 32 is the surface of the photoreceptor 23 after RI for the transfer paper.
The second is a cleaning device that removes remaining toner. As an example of a copying machine, the simplest type that can perform single-sided copying from a single-sided original is shown as an example, but the recording paper processing device of Thu 9.1Jl is not limited to this type of copying machine, but can also perform double-sided copying from single-sided original, double-sided original Of course, it can also be used in combination with a type of copying machine that performs single-sided copying or double-sided copying. In order to make these types of copies, it is necessary to invert the original or invert the transfer paper, and whether a mechanism for this is required in the copying device 2 or RDF device 3, or if these mechanisms are not available. Since this is well known and is not the gist of the present invention, the explanation will be omitted here. Copy paper processing bag according to the present invention'j! As shown in FIG. 1, ti is a conveying roller 41 that discharges the copy eIF copied by the copying machine δ2 and discharged from the copying machine head to a paper discharge tray 4o without bunching or binding it. A transport roller 44 transports the copy F to an intermediate tray 43 called a stacker by switching the path switching gate 42 for bunching or binding, and a transport roller 44 transports the copy F to an intermediate tray 43 called a stacker, and the copy F is bunched to a copy iF corresponding to one copy stored in the stacker 43. It is comprised of a processing unit 45 for punching holes and binding together, and transport rollers 47 and 48 for conveying the copies F that have been subjected to processing such as bunching and binding to a final storage tray 46. The processing unit 45 consists of one bunching machine and two stitching machines (so-called staplers) placed on both sides of the bunching machine. In Figure 1, it can be pulled out (in front of Kawamuka on the paper). This is the disposal of bunch scraps used as a result of bunch processing by a punch machine, binding 11
- This is to facilitate the loading or replenishment of staples (so-called staples) in the sewing machine, or the removal of jammed staples. The storage tray 46 is a platform on which the processed copies F are placed, and is of a human-operated lifting type, and this lifting table 46a is lifted up by a tray lifting motor M++ (see FIG. ing. Copy F on the lifting platform 46a
When a certain limit position is exceeded, tray 4: limit sensor PS,
4, and when it reaches a predetermined lower limit position F, it is detected by the trade limit sensor Ps15. The elevating table 46a is lowered by the tray elevating motor M11, or it is flaked by the solenoid SD2 to prevent the elevating table 46a from being lowered by the insects of the copy F on the +A lowering table 46a Jl. It looks like this. Next, the structure of a copy paper processing apparatus employing the processing unit according to the present invention will be described in detail. FIG. 3 shows a perspective view of the main parts of the copy paper processing device.
The rollers 41a, 41b, 41c, and 41d constitute the conveyance roller 41 together with other rollers (not shown).The path switching gate 42 is driven by a solenoid SO, and when the solenoid SD+ is not energized, the copy is transferred to the paper discharge tray 40.
It assumes a first position t, in which the copies are transported to the stacker 43, and a second position, in which the copies are transported to the stacker 43, when the solenoid SD1 is energized. The rollers 44a and 44b constitute a conveyance roller 44. The stacker 43 has an inclined plate 43a and a sliding plate provided on the L surface thereof at a distance of 2.
It consists of a pair of side plates 43b1 and 43b2, and a stopper 43c provided directly below the inclined plate 43a so as to be movable forward and backward. The inclined plate 43a has a plurality of openings [14: lla, 431b, 411c] formed near the front end, as shown in FIG. and two slots 432a and 432 near the center.

A gear 435 is fixed to the rotating shaft of No. 4. On the other hand, this gear 435 has two sliding members 4 with a gear on one side:
15a, 4:16b or +'a are arranged in an upward row, and each sliding member is attached to the side plates 43b, 43b2 on the front side of the inclined plate 43a by means of metal fittings 4:17, 4:18, respectively.
At the same time, a protrusion is formed in the longitudinal direction on the front side of each sliding member, and this protrusion has a slot 4:
12a and 432b. Near the end of one thrower 1 432a is a side plate GbI, 43b2
An optical sensor (side plate home position sensor) PS is provided to detect the reference position (home position) of the frame, and the home position sensor is detected by detecting light shielding by the standing piece 437a of the metal fitting 437. ing. With such a configuration, when the side plate interval adjustment motor M4 is rotated forward or reverse by a predetermined distance, the sliding members 435a and 4:16b move by a predetermined length in the direction of the solid line arrow or the itC line arrow direction. As a result, the side plates 43b1 and 43b2 either move away from each other to widen the gap between the side plates, or move closer together to narrow the gap between the side plates. Further, as shown in FIG. 3, on the back side of the inclined plate 43a, near the ventilation hole 433, there is a motor M for driving a ventilation fan. And Tact 439 has been added. Next, 1151 is performed for the stopper 43c. As shown in FIG. 5, the stopper 41c includes a plurality of protrusions 440 extending forward like fingers, two protrusions 441 whose tips are bent in the L direction to form an upright piece 441a, and a wide protrusion in the center. 442, and bins 444 extend on both left and right sides of this plate 443. This bottle 444 has grooves 445 provided on the sides of resin guides (only the left guide is shown) that are fixed to the frame of the device on both the left and right sides of the plate 443.
It is engaged with a. In addition, a drive rod 446 extending rearward is attached to the center of the temporary phase 443.

43 is arranged in such a positional relationship that it passes through each of the openings 431a to 431a to 431c and projects above the inclined plate 43a. In the forward position of the plate 443, two of the plurality of protrusions 441 project from the openings 431b onto the inclined plate 43a, and hold the copies that slide down on the upright pieces 441a or on the inclined plate 43a to a certain position. It has a stopper mechanism that stops at. As shown in FIG. 3, the processing unit 45 can be pulled out 78 by a guide rail 45a (in the direction shown by the self-arrow in the figure).
It consists of a frame 45b with a punch machine and two staplers on both sides of the punch machine, and the main part is arranged in the sixth
As shown in the figure. As can be seen from FIG. 6, a punching machine 50 is fixed in the center of the frame 45b, and two binding machines are movably provided on both sides of the punching machine 50, only one of which is shown in the figure. It is shown as 7B removed from the frame 4Sb. The punch machine 50 is reciprocated by a motor (punch drive motor) M6.

5c and 55f to punch pieces of paper (multiple copies) placed on the horizontal stand 5Sc, which is a part of the halter 52. The punch bins 56a, 56b are designed so that the ends of both bins sink into the pin guides 52a, 52b at a position slightly lower than the uppermost position, so that the punched paper pieces can surely come out of the bins. The punch scraps ζ↓ are stored in a case detachably attached to the lower side of the horizontal table 55c. - As mentioned above, since the punch bins 56a, 56b are moved up and down by a mechanism using the motor M6 as a drive source, the raised position of the punch bins 56a, 55b is easier to maintain than in the case where the punch bins 56a, 55b are pulled out using the extension action of a solenoid or spring. It can be set arbitrarily to 17, and it is quiet and does not make any noise when drilling. On the other hand, on the frame 45b of the processing unit 45, two sliding members 57 and 58 are provided in an upward direction on the longitudinal side edges facing each other.
．． A gear (not shown) that meshes with the teeth of the sliding members 57 and 58 is provided in the middle of the sliding members 57 and 58, and the gear is rotated forward or reverse by a motor (binding machine driving motor) M. Fixed plates 59a and 59b for attaching the binding IF machine are fixed near the ends of the sliding members 57 and 58, and when the sliding members 57 and 58 are moved in the direction of the arrow by the rotation of the motor M:l, 121I fixed plate S9a, 59b is still frame 45b
It moves left and right guided by guide rails 453 provided above, and the stapler 60 fixed thereto also moves laterally. As shown in FIG. 6, the stitching machine 60 transmits the rotation of a motor (stitching machine drive motor) M9 to an eccentric crank (IW not shown) via gears 61 and 62, and a lever 63
change to a slow linear reciprocating motion. When the lever 63 reciprocates, the V-shaped lever 54 rotates about the fulcrum A, causing the lever 65 to rotate. When the lever 65 is lowered, the spring 66 is compressed via the U-shaped push-down piece 67, thereby pushing the thin plate 68 down along the guides 1-69. As a result, one of the binding metals filled in the cartridge 7 () is separated by the thin plate 68, and the pieces of paper (multiple copies) that are further pressed and placed on the first binding table 71 are bound to the IF. The stitching machine 60 is installed on the frame 45b by fixing the mounting plate 72 attached to the bottom surface to the fixing plates 59a and S9b. The tip of the punch pin to be pulled out can be raised to a position where it can enter the pin guide, or even if the tip of the punch pin does not go in completely, it should be close to the end face of the pin guide. The effect is f'). Furthermore, instead of using a pin guide, a blocking plate may be provided near the L end of the 4-dimension movement path of the bin guide to prevent the copy paper coming up together with the pin, and the same effect can be expected. FIG. 7 shows a feeding mechanism for sending punched or bound 1F copies from the stacker 43, which is a main part of the final copying device 1, to the next conveying means. A U-shaped support plate 45 ( ) is attached to the center of the plate 443 of the stacker 43 , and supports the guide cup 449 .

The copy is stopped at a portion 41a, and when the copy is transported after processing, the stopper 43C is moved backward, and the feed roller 462 is moved to the inclined plate 4:laL to send out the processed copy. FIG. 8 shows a paper presser bar and its driving mechanism for pressing a plurality of copies placed on the stacker 431- in the vicinity of the punched portion or the +L portion prior to punching or binding. The paper presser bar 80 has a sponge 8 [1a] stretched on the surface of a long metal bar, and is suspended loosely (slidably) from a bar 81 through a central elongated hole. Bar 81 is B

The F device 3 operates as described above, and the lowest original (in this case, the original on page 3 t-, I) is sent out and moved across the glass plate 16'' of the copying device 2. During this time, optical system 1
An electrostatic latent image of the original image irradiated by the photoreceptor 9 is formed on the photoreceptor 237, and a series of electrophotographic processes proceed. On the other hand, copy paper F of ^4 size selected by the size selection button 203 is supplied from the cassette 27. A visible image of the original image is transferred onto the copy paper P by the transfer electrode 28, fixed by the fixing device 30, and then ejected from the device by the paper roller. The ejection of copy paper Fll is detected by a paper ejection microswitch. The ON signal of the copy button 202 is transmitted to the control circuit cpu too of the processing device l, and is activated by the built-in start timer T.
Start M. After a predetermined time period determined by the start timer TM, the copy paper transport motor M2 of the processing device 1 is started. As a result, the first sheet of copy paper F, (3rd page) discharged from the copy bag 2t2 is directed in the discharge direction by the path switching gate 42, conveyed by the conveyance roller 41, and discharged onto the paper discharge tray 40. Ru. The copy paper F is ejected using the paper ejection sensor PS.
The output of the paper discharge sensor PS is once input to the CPU 100 via the sensor input circuit +01, and is also sent to the CPU 200. The CPU 200 counts up at the falling timing of the output of the paper discharge sensor PS. As explained in section 2 of the operation of the RDF device 3, the RD
The F device 3 sends out the 1st original (page 3 1), and then sends out the 42nd original 1c (page 2). The copying device 2 copies the original image in the same manner as the single-sheet copy. The same applies to the third document. The original images thus copied are sequentially discharged from the copy bag 712 following the first sheet. Ejected copy paper FI21Fl: l is processing bag m
The sheet is conveyed by the conveyance roller 41 of 1 and discharged onto the sheet discharge tray 40. During this period as well, the CPU 200 continues to count up at the falling timing of the output of the discharge sensor PSI. In this way, one copy (3 sheets) of copies F + F 12 +
The CPU 2
00, the count value based on the falling edge of the sheet discharge sensor PS is compared with the count value based on the output of the circulation sheet discharge sensor R85 provided in the RDF device 3, and when the two match, the second copy [because it is -1] is compared. Start sending out the original. The feeding of the second document by the RDF device 3, the copying by the copying device 2, and the conveyance and ejection by the copy paper processing device 1 are carried out by l! Since this is completely the same as the case of 'i'l1 mouth, the explanation will be omitted. In Figure 12, the copy of part 2 11 is F
2. , F2□, F2:l. As can be seen from FIG. 12, when the last (first page) copy F2:I of the second copy m-+ is ejected from the copying device 2, and this is detected by the paper ejection microswitch-8, Thereafter, the copying operation ends after a predetermined period of time. When a predetermined time T2 has passed after the end of this copying operation, the copy paper transport motor M
Stop 2. At this time, 1ifl T2 is determined by a stop timer TM2 built into the CPU 100, which starts counting from the copying operation end time t2. This ends the stack mote. Binding 1st mode FIG. 13 shows a timing chart of the binding mode. Press mote selection button 2 (4) on the operation panel twice to select the binding IL mode, and operate size selection button 203 to select copy paper size A4.
For example, the binding position designation button 205 is pressed once to designate the binding position to corner a. Now, when the copy button 202 is turned on at time t,
The originals are sent out one by one by the RDF device 3, copied by an electrophotographic process in the copying unit 212, and then ejected from the main body of the device 2. 1st copy paper F II+ F12+
The discharge of F l:l is detected by the paper discharge microswitch, and the CPU 200 detects this microswitch MS.
The number of ejected copy sheets is counted based on the output. If the number of copy sheets ejected from the copying device 2 (3 in this embodiment) matches the count value (3 in this embodiment) based on the output of the circulation paper discharge sensor R35 of the RDF device 3, then the short period of time is determined. Afterwards, the last paper signal is output. At the same time as this last paper is received, a binding start timer built in the CPU 100 starts counting. - After turning on the copy button 202, cptr+, o. Time T1 determined by built-in start timer TV.
After that, the transport motor M2, the stapler drive motor M3, the side plate interval adjustment motor M4, and the stacker fan drive motor M are activated. As the path switching solenoid SD rotates, the path switching solenoid SD is energized. As a result, the conveyance roller 41 starts rotating, and the two binding rollers 1
Move from the home position toward the punch machine 50 via the tome fi60 or the sliding members 57 and 58, and press the side plate 4:lb
,, 4: lb2 moves from the home position to a position approximately equal to the paper size, the stacker fan starts rotating, and the path switching games 1 to 42 are directed in the copy processing direction. At this time, side plates 43b1 and 43b2 are attached for each sheet of copy paper.
Align the paper by swinging it left and right so as to pinch the paper. When the power is turned on and after the binding process is completed, the binding machine drive motor M:l and the side plate spacing adjustment motor M4 rotate in the forward direction by the number of rotations determined by the selected copy paper size (for example, 20 pulses), and then rotate in the reverse direction. , and for the former, the home positive stain sensor PS. As for the latter, when the home position sensor 1) S4 is turned on, it is configured to stop, respectively, so that it is always located at the home position. In addition, lI! When the four motors M3 and M4 rotate forward at an initial predetermined number of rotations, if the home position sensors ps, o, and PH1 are on, the motors M3 and M4 perform IL rotation until that sensor becomes off. Then, after a period of time T has elapsed from time t1, the binding machine drive motor M3 moves to a position slightly outside of the paper size A4 for binding 1.
The topping machine 60 is moved; it is rotated by a certain amount, and the side plate spacing adjustment motor M4 is rotated by an amount to move the side plates 43b1 and 43b2 to the position of A4, which is approximately the paper size. The binding and binding machine 60 is fixed at a position slightly outside the size of the paper because it is the opening to the processing area for bunching and binding multiple sheets of copy paper.Since it is not that wide, it is possible to hold all the copy sheets or their processing. This is to ensure that it is in the correct position. Copy sheets F1. . F 12+ F I'j is conveyed by a conveying roller 44 in the processing direction through a path switching gate 42, and its discharge to the stacker 4 is detected by a sheet discharge sensor PS2. When the time T3 set by the stapling start timer TM3 elapses after the output of the last paper, the paper presser bar operation timer TM built in the CPU1()0 starts counting, and the paper presser bar drive motor M5 rotates. do. On the other hand, the stacker fan stops at this point. When the time T4 set by the paper presser bar operation timer TM has elapsed, the paper presser bar drive motor M is stopped, and the binding machine drive motor M3 starts rotating again in the direction of the two binding machines or the punch machine 50. Start moving. Motor M:
I rotates and stops so that it is at the binding position of the first binding machine 60 or slightly inside the size 84 selected by the size selection button. When the stapler drive motor M:l stops, the stapler drive motors M9 and Ml,) start rotating. The rotation of the drive motors M 9 and M 1o is transmitted through the gears 61 and 62 as a linear reciprocating motion of the lever 63, causing the ■-shaped lever to rotate about the fulcrum. As a result, the lever 65 rotates, and the push-down piece 67 and the spring 66
descends while compressing. As a result, the thin plate 68 descends along the guide 69, cuts off one binding metal contained in the cartridge 70, bites into the copy, and binds it. When the binding machine drive motors M9 and Mlo stop, the binding + L binding machine drive motor M3 reverses and rotates until the binding machine moves to a position slightly outside of the selected size A4, and then stops. The presser bar drive motor M5 rotates, and the paper presser 8-sensor ps. The motor stops when the home position of the drive motor M5 is detected. Meanwhile, at this time, the stopper drive motor M7 starts to reverse,
As a result, as shown in FIG. 5, the binion 447
rotates, and the drive rod 446 that meshes with it moves backward. As a result, the plate 443 retreats while being guided by the guides 445 on both sides. When the plate 443 retreats to a certain extent, since the groove 445a of the guide 445 is inclined, the protruding pieces 440 and 441 extending in front of the groove 445a of the guide 445 move downward, and the inclined plate 43
Pull in from openings 4:IIa, 4:llb, 4:llc of a. In particular, the upright piece 441a of the projecting piece 441 or the opening 43 +
Copies bound by pulling in from 11 (F

It will be in a state where it can slide. When the stopper 43c is retreated to a predetermined position, the stopper OFF sensor PSI6 is turned on and the stopper drive motor M7 is stopped. When the stopper OFF sensor ps, 6 is turned on and the copy paper transporter M rotates, the shaft 449 shown in FIG.
The feed roller 462 also rotates via the feed roller 462. the result,
A portion of copy paper (F Il+ F 12. F 13) which has been aligned in the binding 1 and is placed on the inclined plate 43a1- is sent out by this feed roller 462 and placed on the inclined plate 43a.
Slide down L. When the two temporary stop sensors PS7 and PS8 arranged in the width direction of the copy paper detect the leading edge of the copy paper sliding down, the conveyance latch IIIc (see Fig. 9) operates and the conveyance rollers 47 and 48 start rotating. . The copy paper is transported by the transport roller 47, and when the leading edge of the copy paper is detected by the tray paper discharge sensor PS6, the stopper drive motor M7 starts to rotate and the plate material 443 is advanced by the mechanism shown in FIG. When the tray discharge sensor PS6 detects the trailing edge of the copy paper and its output turns off, the M1 off timer TM5 built in the CPU starts counting. When the predetermined time T5 set by the off-timer TM5 has elapsed, the copy paper transport motor M is activated. Then, the stacker fan drive motor M8 starts again and starts blowing air. During this time, the stopper 430 moves forward, and when it reaches a predetermined stop position, the output of the stopper ON sensor PS5 turns off. At this timing, the lever drive motor M7
or stop. One portion of double 9J paper (F ll + F 12.
F+3) rides on the lifting platform 46a of the storage tray 46. While the above-mentioned stitching process for copy paper 1 is being performed in the processing device 1, the RDF device 3 is
Sequentially sending out originals for copy paper processing in step 1,
The copying apparatus 2 performs a copying operation using an electrophotographic process in the same manner as in the case of the first copy. As shown in FIG. 13, the second copy F2. . When F2□ and F23 are sequentially ejected from the copying device 2 and detected by the paper discharge microswitch MS to output a last paper signal, the binding start timer TM3 is started to measure the set time T□. After the set time T3 has elapsed, the CPU 1.00 built-in paper presser bar operation timer TM starts counting, and the paper presser bar drive motor M5 starts counting.
or rotate. The subsequent operation sequence of the timer and motor is the same as that for the first copy, so a description thereof will be omitted. The difference in the operation sequence from the first copy process is the movement of the binding IL binding machine 60 and the side plate [b, , 43
This is the movement of b2. That is, the first stitching machine 6 ( ) returns to the home position after the first stitching operation. This is binding 1
The first machine 60 has reached the home position.■
This is realized by continuing to rotate the side-stitch IL stitching machine drive motor M, which is detected by the stitching machine home position sensor ps, . The side plates 43b1 and 43b2 are also returned to the home position, but this is because the side plate home position sensor 1) S4 detects that the side plates have reached the home position.
This is achieved by continuing to rotate. This example shows an example of making two copies, so C

Even when measuring T5, the stacker fan drive motor M
. will not start. In this way, the binding mode ends. Punch/stitch 1st mode FIG. 14 shows a timing chart of the punch/stitch 1st second mode. The user operates the mode selection button 204 on the operation panel to select the punch/stitch mode, and also operates the size selection button 203 to select copy paper size 84. Further, the user presses the punch designation button 206 to instruct "low punch". As can be seen by comparing the timing chart of No. 141"l with the timing chart of FIG. and the punch sensor PS9 sequence are added. Therefore, regarding the binding IF operation, please refer to the above-mentioned section on the first binding mode, and below, only the punching operation will be explained. When the set time T3 of the paper presser bar operation timer built into the CPU 100 has elapsed, the punch drive motor MG starts rotating. As shown in FIG. 6, in the punch machine 50, when the punch drive motor M6 rotates, the ohm gear 51 also rotates, and the gear 53 connected thereto also rotates. As a result, two eccentric gears 5 are fixed to the rotating shaft of the gear 53.
4a, 54b rotate or two eccentric blocks 54a
, 54b are fixed in a positional relationship shifted by a certain rotation angle (for example, 50 degrees), so that the raccoon moving pieces 55a and 5Sb
punch bin 56a via. The punching operation by 56b also lags in time. By doing so, it is possible to reduce the load on the punch drive motor M6. When it is detected that either the bunch sensor PS9 or the punch drive motor M6 has rotated once and the output changes from "H" to "off", the punch drive motor M6 stops. As you can see from the timing chart of No. 141'4,
In the middle of the punching operation, the first copy sheet FIl+F was subjected to the binding operation described above and one-copy processing was performed.
+2. +F l:l is the conveyance roller 47. , '18 and discharged onto the storage tray 46. The discharge operation after the second processing of punching/stitching 11 is the same as the above-mentioned case of only the binding/registration processing, so a description thereof will be omitted. Next, the punching and binding first topping process for the second copy 11 is completely the same as for the first copy, so a description thereof will be omitted. Thus two copies F2. , F2□+F2:l is discharged to the storage tray 46 in the same manner as the 17th copy after punching with the bunch and binding with the binding machine. As in this embodiment, if two copies are to be made, the lifting table 46 may be out of range, or if the number of copies to be made at one time is large.
When the tray upper limit sensor PSI4 detects that the uppermost copy of the duplicates stacked one after another on a has exceeded the predetermined upper limit level, the train 1 lowering motor M
11 rotations to lower the lifting platform 46a by one step. At this time, solenoid SD2 is activated and tray) 1 lowering motor M
Apply a brake to the rotating shaft of No. 11 to prevent it from descending to the lifting platform 46a or higher. As the number of copies on the elevating table 46a increases, the rotational movement collapses. In this way, the copies are piled up on the Sea 1 descending platform 46a'', and the
When the tray lower limit sensor ps, . . . 5 detects that the tray a has been lowered to the lower limit t, an over-discharge signal is output. Based on this belief that the discharge is over, a warning lamp may be turned on or a warning buzzer may sound. Is it suitable to use the unreleased recording paper processing device in combination with a copying device as a copy paper processing device?The device to be combined with M1 is not limited to a copying device, but also a printer that processes multiple sheets of paper, such as a printing machine or a cart processing machine. Of course, a recording device that handles documents may also be used. (Effects of the Invention) - As explained above, in the present invention, a set of recording sheets fed one by one from the outside are stacked and held in the order in which they are fed,
In a recording paper processing device configured to punch or staple a set of recording paper at the holding position, when the bunch pin is removed after punching, almost the tip of the punch pin goes into the bunch guide. After configuring it, when you remove the bunch pin, the copy will come down with the pin, and the tip of the copy will not be disturbed.
