Description

The present invention relates to a recording paper processing apparatus suitable for use in combination with a recording apparatus such as a copying apparatus.

(Background of the Invention) Recently, recording apparatuses such as printers and facsimile machines have been widely used in various fields in addition to conventional copying machines. In particular, copying machines tend to be faster and more multifunctional.

On the other hand, when making conference materials or materials for distribution using recorded materials such as copying machines, it is necessary to align, fold, puncture, or bind the recorded materials after recording. It is considered to improve the efficiency of total copy work by automating the process of sorting, sorter, automatic punching machine, automatic paper folding machine, automatic collating machine, or a processing device having a combination of these, which sorts copies. (For example, JP-A-61-94180, JP-A-61-84662, Journal of the Electrophotographic Society of Japan, Vol. 24, No. 3, (1985), pp. 188-194).

By the way, a series of recorded materials is usually stapled,
It is often used and stored by binding it to a file. However, there has not been proposed a processing apparatus that can simultaneously perform punching and stapling for processing a recorded material.

In view of the above, the present inventors have made a patent application “Recording Paper Processing Apparatus” dated January 23, 1987, an intermediate holding unit that holds a set of recording papers supplied one by one from the outside in a supply order,
A processing unit that selectively punches or binds a set of recording paper held in the intermediate holding unit at the holding position, a storage unit that stores processed recording paper, and a storage unit that stores processed recording paper. The present invention has proposed a recording paper processing apparatus including a first transport unit that transports the recording paper to the intermediate holding unit and a second transport unit that transports the processed recording paper to the storage unit. If this processing apparatus is used in combination with a recording apparatus such as an electrophotographic copying apparatus, a set of recorded materials is automatically punched or bound, which is convenient for preparing conference materials and distribution materials. .

By the way, a stapling machine used for stapling processing in this type of processing apparatus has a cradle and a stapler pressing plate similarly to a widely used stapler, and a plurality of staplers to be stapled at the openings of both. Then, the binding staple pressing plate is pushed down with the recording paper interposed therebetween, thereby causing the binding staples to bite into the recording paper to stop the binding.

However, the number of recording papers that you want to bind at once varies, and in some cases it is quite large.Some recording papers are curled in the binding part, so they enter the opening of the binding machine smoothly. It can be difficult.

(Object and Configuration of the Invention) In a recording paper processing apparatus for performing binding processing by stacking a plurality of recording papers, a recording paper to be subjected to binding processing is located at a binding stop position. In order to achieve this purpose, the stapling machine for stapling is temporarily moved to near the recording paper prior to the stapling operation, and then moved to the stapling position. Configured.

(Example) Hereinafter, the present invention will be described with reference to the drawings.

A processing apparatus exemplified next is a copying paper processing apparatus used in combination with a copying apparatus. As schematically shown in FIG. 1, a copying paper processing apparatus 1 is connected to a copying apparatus 2 at a position indicated by a broken line E. used.

Prior to the description of the copy paper processing apparatus 1 to which the present invention is applied, the copy apparatus 2 will be briefly described.

A copy paper processing apparatus to which the present invention can be applied is a copy manuscript composed of a plurality of sheets (for example, 5 pages from page 1 to page 5 of a book).
) To obtain at least one copy, and to punch or bind the copy, so that the copying apparatus has a function of sequentially and repeatedly copying a plurality of copies. For this purpose, a circulating automatic document feeder (hereinafter referred to as RDF device) is used.

As can be seen from FIG. 1, the copying apparatus 2 is equipped with an RDF apparatus 3 on the upper part, and is configured to copy the originals fed one by one by the RDF apparatus 3 by a normal electrophotographic process. . Since the general structures and functions of the copying apparatus 2 and the RDF apparatus 3 are already known, they will be briefly described.

The RDF device 3 includes a glass plate 1 provided on an upper surface of the copying device 2.

Here, when a copy button provided on the operation panel of the copying machine 2 is pressed, the rear end regulating plate 12 of the RDF device 3 moves forward to push the entire original G forward (to the right in the drawing) and to move the original G along the front passage. The gate 13 at is raised. And the document G passes through the gate 13 original leading edge detecting sensor RS ₂ when the leading edge of the document is detected trailing end regulating plate 12 is stopped by at that somewhat progressed, the gate 13 is lowered and the rear end regulating plate 12 is retracted .

Here, when a document feed signal is output from the copying apparatus 2 at a predetermined timing, the half-moon feeding roller 14 rotates once and the double feed prevention roller 15 rotates to feed only one lowermost document. It is. The sent original is a guide plate 16
Advanced along, sent by the feed roller 17, is the leading edge detection by the timing sensor RS _3, moves on the glass plate 10 of the copying apparatus 2 is taken over by the conveyor belt 18 at a predetermined speed. Below the glass plate 10, an optical system 19 including a lamp for irradiating the original and a reflecting mirror is provided, and the original is exposed while being moved by the optical system 19. When a document leading edge detection signal from the timing sensor RS ₃ is sent to the copying apparatus 2, the feeding of the transfer paper in the copying apparatus 2 starts. Document having been subjected to the exposure is detected by the discharge sensor RS _4, is transported by another conveyor belt 20, rests on the rest of the document placed on the document placing plate 11. The final discharge of the original is detected by the circulation paper discharge sensor RS _5. Jam in document feed can be known by detecting the timing of the timing sensor RS ₃ and the sheet discharge sensor RS _4.

It sends out the second document starts when the trailing edge of the first document is detected by the timing sensor RS _3.

3 sheet In the same manner, 4 th, ... and the exposure by the optical system of the copying apparatus for all of the document is completed, 0 Like the number of documents by the document leading edge detecting sensor RS ₂ is confirmed, thus copies a portion of The document feeding ends.

If a plurality of copies (e.g., five copies) of the same copy are to be made, the document is automatically fed again from the last page of the document again, and exposure is sequentially performed on one page. This document feeding operation is repeated for the required number of copies.

The following electrophotographic process is performed in the copying apparatus 2 in synchronization with the above operation of the RDF apparatus 3.

When a document passing at a constant speed on the glass plate 10 of the copying apparatus 2 is exposed by the optical system 19, the reflected light from the document is projected onto the photosensitive member 23 via the mirror 20, the lens 21, and the mirror 22. . Since the surface of the photoconductor 23 is uniformly charged by the charging device 24, an electrostatic latent image is formed when reflected light from the document is projected. The electrostatic latent image is developed into a visible image by the developing device 25, and is transferred onto the transfer paper P fed from one of the paper feed sets 26 and 27 in synchronization with the automatic document feeding operation. Transcribed by 28.

The transfer paper on which the visible image has been transferred

In addition, the operation panel of the copying apparatus 2 is provided with a concentration adjusting means and a magnification selecting means such as reduction or enlargement, but these operation means are not directly related to the present invention, and thus are omitted here. I do.

Next, the operation of the copy sheet processing apparatus will be described. The copy paper processing apparatus according to the present embodiment operates in the following three processing modes.

(B) Stack mode Just copy the original, just like a normal copying machine.
A mode in which the sheets are discharged to the paper discharge tray 40 without being punched or bound. In this mode, the binding stop position designation button 205 is used to determine whether the binding position is only the corner a of the copy as shown in FIG. 11, only the other corner b, or both corners a and b. You can choose.

(C) Punching / binding mode Punching a plurality of copies and binding them with a binding metal. In this case, the punch designation button 206 is pressed, the punch position is set at one central position, and the binding stop positions are only a, b only, and a as in the binding stop mode.
And b can be selected. Hereinafter, a case will be described as an example where two copies of an A4 original are made by copying three originals.

Regardless of the processing mode in which the copy paper processing apparatus is operated, first, the power switch 301 of the copy apparatus 2 is turned on, and R
Three originals are stacked on the original mounting plate 11 of the DF device 3 in the order of first page, second page,... From the top.

When the power switch 301 is turned on, the following initial settings of each load are performed. That is, the stapling machine moving motor M ₃ set number of pulses (e.g. 20 pulses) only is reversed after forward rotation, is stopped when the stapling machine home position sensor PS ₁₀ is turned on. The plate spacing adjustment motor M ₄ is reversed after forward rotation by the number setting pulses (e.g. 20 pulses), it is stopped when the side plate home position sensor PS ₄ is turned on. Paper pressure bar drive motor M ₅ is rotated forward until on paper pressing bar sensor PS ₁₁ is, the punch driving motor M ₆ is rotated forward to the punch sensor is turned on. Stopper drive motor M ₇ is rotated forward until turned stopper ON sensor PS ₅ is then reversed a predetermined time after the paper pressure bar drive motor M ₅ and initializes the punch driving motor M ₆ is completed. Stitching machine drive motors M ₉ and M ₁₀ are stitching machine sensors PS
₁₂ , and only when PS ₁₃ is on, rotate until those sensors are off. The above is the initialization operation.

Stack mode FIG. 12 shows a timing chart of the stack mode.

Press the motor selection button 204 on the operation panel of the copier 2
Press twice to select stack mode.

On the other hand, the user presses the size selection button 203 four times to select the copy paper size A4.

Now, when turning on the copying button 202 at time t _1, RDF unit 3 already original bottom operates as described (in this case a 3-page document) is fed copier second glass plate 16 Moved up. During this time, an electrostatic latent image of the document image irradiated by the optical system 19 is formed on the photoconductor 23, and a series of electrophotographic processes proceeds.

On the other hand, the A4 size copy paper F selected by the size selection button 203 is supplied from the cassette 27, the transfer electrode 28 transfers the visible image of the original image onto the copy paper P, and is fixed by the fixing device 30. The sheet is discharged from the apparatus by a sheet discharge roller 31. Discharge of the copy sheet F ₁₁ is detected by the paper discharge microswitch MS.

The ON signal of the copy button 202 is transmitted to the control circuit CPU of the processing device 1.
Is transmitted to the 100 to start the start timer TM ₁ of the built-in.
After by start timer TM ₁ for a predetermined time, the copying paper conveying motor M ₂ of the processing apparatus 1 is started. As a result, the copying apparatus 2
The first copy paper F ₁₁ (third page) discharged from the printer is directed in the discharge direction by the path switching gate 42, conveyed by the conveyance rollers 41, and discharged to the paper discharge tray 40. Sheet discharging the copy sheet F ₁₁ is detected by the paper discharge sensor PS _1, the output of the paper discharge sensor PS ₁ is temporarily inputted to the CPU100 through the sensor input circuit 101 is also sent to the CPU 200. CPU200 is counts up at the timing of the falling of the output of the discharge sensor PS _1.

As described above, the operation of the RDF device 3 causes the RDF device 3 to send out the first document (the third page), and then sends out the second document (the second page). The document image is copied in the same manner as described above. The same applies to the third document. The document images copied in this manner are sequentially discharged from the copying apparatus 2 following the first sheet. Ejected copy paper F ₁₂ ,
F ₁₃ is discharged to the paper discharge tray 40 is conveyed by the conveying rollers 41 of the processing apparatus 1. During this time also CPU200 is going to count up at the fall timing of the output of the discharge sensor PS _1.

Thus while the copy of the one part (3 sheets) fraction F _11, F _12, F ₁₃ is discharged to the ejection tray 40, the count value and the RDF device 3 based on the falling edge of the CPU200 in discharge sensor PS ₁ count value is compared based on the output of the provided circulating discharge sensor RS _5,
When they match, feeding of the original for the second copy starts.

The sending of the second document by the RDF device 3 and the copying to the copying device 2 and the transport and discharge by the copy paper processing device 1 are exactly the same as those of the first copy, and therefore the description is omitted. In FIG. 12, the copy of the second copy is shown as F ₂₁ , F ₂₂ , and F ₂₃ .

As can be seen from FIG. 12, copies F ₂₃ of the second set of the last (first page) is discharged from the copying apparatus 2, when the it is detected by the paper discharge microswitch MS, then copy after a predetermined time The operation ends. The copying operation after the end of the predetermined time T ₂ stops copying paper conveying motor M ₂ when elapsed.
The time T ₂ are start counting from the copying operation is finished time t ₂
Defined by CPU100 internal stop timer TM _2.

 Thus, the stack mode ends.

Binding Mode FIG. 13 shows a timing chart of the binding mode.

By pressing the mode selection button 204 of the operation panel twice to select the binding mode,
To select the copy paper size A4. Further, the binding position designation button 205 is pressed once, for example, to designate the binding position as the corner a.

Now when you turn on the copy button 202 at time t _1, RDF
Documents are sent out one by one by the apparatus 3, copied by an electrophotographic process in the copying apparatus 2, and discharged from the apparatus 2 body. The discharge of the first copy sheets F ₁₁ , F ₁₂ , and F ₁₃ is detected by the discharge micro switch MS, and the CPU 200 counts the number of discharged copy sheets based on the output of the micro switch MS. The number of copy sheets (3 in this embodiment) discharged from the copying apparatus 2 is determined by the circulating discharge sensor RS _{5 of the} RDF apparatus 3.
When the count value coincides with the count value (3 in this embodiment) based on the output of (1), the last paper signal is output a short time after that. At the same time as the last paper signal, a binding start timer built in the CPU 100 starts counting.

On the other hand, when the time T ₁ determined by the start timer TM ₁ built in the CPU 100 elapses after the copy button 202 is turned on,
A transport motor M _2, a stapling machine moving motor M _3, a side plate spacing adjustment motor M _4, the path switching solenoid SD ₁ is energized with the stacker fan drive motor M ₈ rotates. As a result, the transport roller 41 starts rotating, and the two stapling machines
60 through the sliding member 57, 58 is moved from the home position in the direction of the punch unit 50, the side plates 43 b _1, 43 b ₂ is moved to a position substantially equal to the paper size from the home position, the stacker fan starts rotating, The path switching gate 42 is directed in the copy processing direction. At this time, the side plate 43 is provided for each copy sheet.
b ₁ is swung to the left and right so as to sandwich a 43 b ₂ by performing alignment paper.

Stapling machine driving motor M ₃ and the side plate spacing adjustment motor M ₄
Where the after power-up and prior stapling process by forward by a rotation speed determined by the copying paper size selected (e.g. 20 pulses) and then reversed, for further former home position sensor PS ₁₀ is turned on Further, for the latter are located always home position so are be stopped respectively at the home position sensor PS ₄ is turned on. Note that when the home position sensor PS ₁₀ and PS ₄ when the first predetermined rotational speed forward Both motors M ₃ and M ₄ are turned to the forward until the sensor is turned off.

Therefore the time t ₁ stapling machine moving motor M ₃ to the time T ₁ elapses after is rotated by an amount that moves the stapling machine 60 only to the outer position slightly outside the position, for example 30mm from the paper size A4, plate spacing adjustment motor M ₄ is rotated by an amount of moving the side plates 43 b ₁ and 43 b ₂ to near the position of A4 is paper size. The reason why the binding stapler 60 is held at a position slightly outside the paper size is that the opening to the processing position for punching and binding a plurality of copy papers is not so wide, so that all the copy papers are in the processing position. In order to be sure to enter. In addition, by moving the binding device 60 immediately before the copy paper before the actual binding operation, the binding position (position slightly inside the paper size A4) is actually set thereafter.
And the time required for the binding operation can be reduced. According to the experiments of the present inventors, when the binding device 60 was moved from the home position to the binding position, it took 1.8 seconds for the B5 size, but once the recording paper was slightly outside as in this embodiment. It takes less than 0.6 seconds to move to the binding stop position after moving to.

The copy papers F ₁₁ , F ₁₂ , and F ₁₃ sequentially sent to the processing apparatus 1 are transported by a path switching gate 42 toward a processing direction by conveying rollers 44
The paper is conveyed to the stacker 43 by the paper discharge sensor PS.
Detected by ₂ .

When after the output of the last feeding signal stapling start timer TM ₃ set time by T ₃ has elapsed, the paper pressure with a bar operated timer TM ₄ starts counting built in CPU 100,
Paper pressure bar drive motor M ₅ is rotated. On the other hand, the stacker fan stops at this point. When the time T ₄ set by the paper holding bar operation timer TM ₄ has elapsed, the paper holding bar drive motor M ₅ is stopped and the binding stopper moving motor M _{3 is} stopped.
Starts rotating again, and the two stapling machines start moving toward the punching machine 50. Motor M ₃ represents stapling position of the stapling machine 60 is stopped rotating as on the inside only slightly inside example 24mm size A4 selected by size selection button.

Now when the stapling machine moving motor M ₃ stops the stapling drive motor M ₉ and M ₁₀ start rotating. Drive motor M
The rotation of M ₉ and M ₁₀ is transmitted as a linear reciprocating motion of lever 63 via gears 61 and 62, and rotates the V-shaped lever about fulcrum A. As a result, the lever 65 rotates and the pressing piece 67
Moves down while compressing the spring 66. As a result, the thin plate 68 descends along the guide 69, and only one stapler contained in the cartridge 70 is cut off and cut into the copy so as to be stapled.

When the binding-stopper drive motors M ₉ and M ₁₀ stop, the binding-stopper moving motor M ₃ rotates in the reverse direction and stops after rotating the binding-stopper to a position slightly outside the selected size A4, and then stops. presser bar driving motor M ₅ is rotated, stops when the home position of the drive motor M ₅ is detected by the paper pressing bar sensor PS _11.

On the other hand, at this time, the stopper drive motor M ₇ starts reverse rotation,
As a result, as can be seen from FIG. 5, the pinion 447 rotates, and the driving rod 446 engaged with the pinion 447 moves backward. As a result, the plate member 443 retreats while being guided by the guides 445 on both sides. When the plate material 443 retreats to some extent, the groove 44 of the guide 445
Protrusions 440, 4 extending forward because 5a is inclined
41 descends and retracts from the openings 431a, 431b, 431c of the inclined plate 43a. Especially upright 441a is stapling been copies by pulling from the opening 431b of the protrusion _{441 (F 11, F 12,} F 13) is in a state capable of sliding on the inclined plate 43a. Stopper drive motor M ₇ because the stopper 43c a stopper OFF sensor PS ₁₆ when retracted to a predetermined position is turned on is stopped.

If on the same time copying paper conveying motor M ₁ of the stopper OFF sensor PS ₁₆ is rotated, the shaft 466 shown in FIG. 7 is rotated, the feed roller 462 rotates via rollers 463, 464 and the belt 465. As a result, the binding is stopped and the inclined plate 4
1 part of the copy sheet resting on _{3a (F 11, F 12,} F 13) is slid down over sent out to the inclined plate 43a by the feed roller 462. Upon detecting the leading edge of the copy sheet in which two of the temporary disposed in the width direction of the copy paper stop sensor PS ₇ and PS ₈ is slid down, the conveying rollers 47 and 48 rotate working conveyance clutch MC (see FIG. 9) is start. Copying paper is conveyed by the conveying rollers 47, sheet 443 by a mechanism shown in Figure 5 when the leading end is detected by the tray sheet discharge sensor PS ₆ stopper drive motor M ₇ starts rotating to move forward.

M ₁ off-timer TM ₅ whose outputs are built into CPU100 where turned off tray discharge sensor PS ₆ is detected the trailing end of the copying paper begins to count. When the M ₁ off timer TM predetermined time T _5, which is set by ₅ passes, copying paper conveying motor M ₁ is stopped, the stacker fan drive motor M ₈ is started again blowing begins.

Stopper 43C is advanced during this period, the output of the stopper ON sensor PS ₅ is turned off when it reaches a predetermined stop position. Stopper drive motor M ₇ at this timing is stopped.

One portion of the transported copy paper (F ₁₁ , F ₁₂ , F ₁₃ ) rides on the elevating platform 46 a of the storage tray 46.

While the binding stop processing of the first copy sheet is being performed in the processing apparatus 1 as described above, the RDF apparatus 3 sequentially sends out originals for the processing of the second copy sheet, and the copying apparatus 2 As in the case of the first copy, the copying operation by the electrophotographic process is performed.

As shown in FIG. 13, when the second copy F ₂₁ , F ₂₂ , F ₂₃ is sequentially discharged from the copying apparatus 2 and detected by the discharge micro switch MS ₁ to output the last paper signal, the binding is performed. the stop-start timer TM ₃ for measuring a set time T ₃ to start. With set time T ₃ CPU 100 built after the paper presser bar actuation timer TM ₄ starts counting, the paper pressure bar drive motor M ₅ is rotated. The subsequent operation sequence of the timer and the motor is the same as in the case of the first copy, so that the description is omitted. The operation sequence differs from the first copy processing in that the movement of the binding stopper 60 and the side plate 43 are different.
This is the movement of b ₁ and 43b ₂ . That is, the binding stopper 60 returns to the home position after the binding operation. This is a binding machine
60 is achieved by continuously rotating the stapling machine driving motor M ₃ to be detected by the stop unit home position sensor PS ₁₀ binding that has reached the home position. The side plates 43b ₁ and 43b ₂ are also returned to the home position, which is realized by continuing to rotate the side plate distance adjustment motor M ₄ until the side plate home position sensor PS ₄ detects that the side plate has reached the home position. Is done.

Since this embodiment shows an example of making two copies,
Stacker fan drive motor M ₈ also when the CPU100 built of M ₁ off-timer TM ₅ was measured T ₅ time does not start.

 Thus, the binding mode ends.

FIG. 14 shows a timing chart of the punch and binding mode.

By operating the mode selection button 204 on the operation panel to select the punch / binding mode, the size selection button 203 is operated to select the copy paper size A4. Further, the user presses the punch designation button 206 to instruct “punch required”.

14 a timing chart of Figure As can be seen when compared to the timing chart of FIG. 13, only been added exactly the same punch operation for stapling operation, the punch drive mode M ₆ and the punch sensor PS for this ₉ sequences are added.

Therefore, for the binding operation, reference should be made to the above-described binding mode, and only the punch operation will be described below.

Set time of paper press bar operation timer built in CPU100
When T ₃ has elapsed, the punch driving motor M ₆ starts to rotate. As shown in FIG. _6, when the punch drive motor M6 of the punching machine 50 rotates, the worm gear 51 rotates, and the gear 53 meshed with the worm gear 51 rotates. As a result, the two eccentric blocks 54a and 54b fixed to the rotation shaft of the gear 53 rotate,
The two eccentric blocks 54a and 54b have a certain rotation angle (for example, 50
(°)
The punching operation by the punch pins 56a and 56b via the holes 55a and 55b is also shifted in time. In this way, it is possible to reduce the added according to the punch driving motor M _6.

When the punch sensor PS ₉ detects that the punch drive motor M ₆ has made one rotation and its output changes from “H” to “L”, the punch drive motor M ₆ stops.

As can be seen from the timing chart of FIG. 14, the above-described stapling work is performed during the punching work, and the copy sheets F ₁₁ , F ₁₂ , and F ₁₃ of the first set subjected to both processes are transported by the transport rollers 47 and The sheet is conveyed by and discharged to the storage tray.
The discharging operation after the punching / binding processing is the same as the case of the above-described binding processing alone, and thus the description is omitted.

Next, the punching / binding processing for the second copy sheet is exactly the same as that for the first copy sheet, and therefore the description is omitted.

When the two copies F ₂₁ , F ₂₂ , and F ₂₃ are punched and stapled by the stapler, they are discharged to the storage tray 46 in the same manner as the first copy.

There is no problem when two copies are made as in the present embodiment, but when the number of copies to be made at one time is large, the elevator 46 is used.
The tray upper limit sensor indicates that the top copy of the duplicates that have been successively discharged on top of a has exceeded the predetermined upper limit level.
Once detected by the PS _14, the tray elevating motor M ₁₁ causes the one step lower the lifting table 46a is rotated. In this case the lifting platform 46a by braking the rotary shaft of the tray lifting motor M ₁₁ solenoid SD ₂ is actuated to block the descending further. The same operation is repeated as the number of copies on the lift 46a increases. Thus we ride overlap copies on lifting table 46a, it outputs a discharge-over signal when the elevator platform 46a has decreased to the lower limit position descends is detected by the tray lower limit sensor PS _15. A warning lamp may be turned on or a warning buzzer may be sounded based on the over-discharge signal.

In the above-described embodiment, when the stapler loaded in the stapling machine runs out, a stapling signal is output from a sensor provided in advance to warn the user, or the punching chips generated at the time of punching become full in the container. Is useful for warnings.

In the embodiment, the binding position is a fixed position at a corner of the copy, and the punch position is also a fixed position at the center of the copy, but the binding position and the punch position may be freely changed. Good.

Further, in the above embodiment, it is needless to say that the present invention can be applied to a recording paper processing apparatus capable of performing a punching process and a binding stopping process.

The recording paper processing apparatus of the present invention is preferably used as a copy paper processing apparatus in combination with a copying apparatus. However, the combination partner is not limited to the copying apparatus, and a plurality of fixed forms such as a printing machine or a card processing machine may be used. It goes without saying that a recording device for handling documents may be used.

(Effects of the Invention) As described above, in the present invention, a set of recording sheets supplied one by one from the outside is held in an overlapping manner in the supply order,
In a recording paper processing apparatus configured to perform a punching process or a binding stop process at the holding position, the binding stop device for the binding stop process is temporarily moved to near the recording paper prior to the binding operation, and then moved to the binding stop position. With this configuration, even if the binding section of the recording paper to be bound is curled, or if the number of recording papers is large and thick, the recording paper will stay in the binding position regardless of the size of the machine opening. Introduced and securely bound. Further, there is an effect that the time required for the binding stopping process is reduced.
