Detailed Description of the Invention [Field of Industrial Application] The present invention provides a sorter having bins arranged in multiple stages in the vertical direction, an aligning means for aligning sheets discharged onto the bins to one end side, and a stabilizer. The present invention relates to a paper post-processing device comprising:

[Conventional technology]

In order to stabilize the stack of sheets discharged into each bin of the sorter using the stabilizer, it is necessary to align the sheets with one side edge of the bin.

For this reason, various paper alignment mechanisms have been proposed. For example, Japanese Patent Laid-Open No. 154576/1983 discloses a technique for aligning sheets by bringing a plurality of aligning members into contact with the sides of the sheets.

[Problem to be solved by the invention]

The above-mentioned conventional technology has the disadvantage that a plurality of alignment members are required and that the structure is complicated and costs are high because the plurality of alignment members are moved.

An object of the present invention is to provide a sheet post-processing device that can align sheets with a simple configuration.

[Means to solve the problem]

The above object is to provide a paper post-processing device comprising a sorter having bins arranged in multiple stages in the vertical direction, an aligning means for aligning the sheets discharged onto the bins to one end side, and a stabilizer, wherein the aligning means has multiple stages. It consists of a swing shaft that penetrates the bottle and is movable in the width direction of the bottle, and a fence that stands up on the end face of the bottle on the opposite side of the swing shaft. The distance is achieved by making the swing axis a distance that allows the various sizes of paper to be moved in parallel.

[Effect]

The aligning means consists of a single swing axis and a fence, and this drawing axis is located at a position (position from the rear end of the bin) that allows paper to be aligned in parallel from large size paper to small size paper. , for example, at a position 125 to 140 mm away from the rear end of the bottle.

The sorter of this embodiment is a 20-bin sorter as shown in FIG.
2.324 are provided at the top and bottom respectively. These sensors 321, 323, 322, and 324 are transmission type optical detection sensors consisting of an LED and a phototransistor. Paper ejection sensors 322 and 324 operate to detect whether copy paper has been ejected, and bin sensors 321 and 323 operate to determine whether copy paper is present in the bin 350. .

FIG. 3 is a front view showing details of the upper conveyance section 100, and FIG. 4 (
a) is a side view showing details of the upper conveyance section 100, in which the copy paper discharged from the copying machine main body is placed on the guide plate 101.1.
02 and transported to the switching claw 103. This switching claw 103 is connected to a switching solenoid (SQL) 107 via links 104, 105, and 106, and when the solenoid 107 is turned off, the copy paper is transferred to the diagonal section 200 provided below the upper conveyance section lOO. Further, when the solenoid 107 is turned on, the respective materials are fed into the upper conveying section 100.

When the solenoid 107 is turned on, the switching pawl 103 is operated, and the copy paper guided into the upper conveying section 100 is moved to the switching pawl 1.
It is sent to the conveying roller lO8 provided immediately above the roller 03. The conveying roller 108 is made of EPDM or chloroprene rubber, and is moved by the driven roller 10 under the action of a leaf spring or the like.
9 is pressing, and conveying force is obtained. The conveying devices constituted by a combination of these conveying rollers 108 and driven rollers 109 are arranged in three vertical rows and convey the copy paper upward one by one. In this conveyance device, the copy paper is transferred to the guide plate 10.
1 and the guide plate 1) 0, and is conveyed to the discharge roller 1) 1, and is discharged to the bruft tray 1) 6.

The above-mentioned driven roller 109 and switching pawl 103 are attached to the guide plate 1) 0, and as shown in the plan view of the guide plate 1) 0 portion shown in FIG. 4(b), the bin 1) 2 on the back side
It is designed to rotate and open around the center. By rotating and opening this guide plate 1) 0, the switching pawl 103 or the driven roller 109 is opened, making it easy to handle paper jams and the like in this area.

Copy paper conveyed by three vertical rows of conveying rollers 108 and driven rollers 109 is guided by guide plates 101, 1) 4, and is conveyed to a discharge roller 1) 1. The material of the discharge roller 1) 1 is also made of EPDM or chloroprene rubber like the conveyance roller 10B, and the discharge roller Il is made of EPDM or chloroprene rubber.
The driven roller 1) 5 of l is also the driven roller 109 of the conveying roller 108.
Similarly, it is pressed by a temporary spring or the like and has a discharging force.

The copy paper that has been conveyed to the discharge roller 11l is discharged to the brochure tray section 1) 6 shown in FIG. 1 by the action of the discharge roller 1) 1 and the driven roller 1) 5. As shown in FIG. 1, the bruft tray section 1) 6 is located closer to the main body than the sorting bin 350. This means that the copy paper can be brought closer to the operator, which improves operability by making it easier for the operator to see and take out the copy paper, and also shortens the transport distance of the copy paper, reducing the time it takes to eject the paper. It has also been shortened. Further, since this proof tray portion 1) 6 also serves as a part of the upper cover, which is an exterior body, there is no need to provide a dedicated proof tray.

FIG. 5 is an explanatory diagram showing the drive system of the upper conveyance section 100, and the upper conveyance section 100 is independently provided with a motor 1) 7.
The driving force is transmitted by the timing belt 1) 8 through gears 130 and 131 to the timing pulleys 1) 9 and 120 fixed to the shafts of the conveyance roller 108 and the discharge roller 1) 1, respectively. 1) The configuration is such that the drive unit 1 is driven.

Further, a feature of the upper conveyance section 100 described above is that no rollers for conveyance are provided between the main body discharge section and the switching claw 103. In the mode in which the blueprint tray section 1]6 is used, the copy paper is conveyed by simply operating the drive motor 1)7 of the upper conveyance section 100 and the solenoid 107, and in the mode in which the bin 350 is used, the copy paper is conveyed in the upper conveyance section 100. The drive motor l17 and the solenoid 107 are configured so that they do not need to be supplied with power, and are configured to efficiently supply power.

This upper conveyance section 100 is unitized and can be easily attached and detached. For example, as shown in the front view of another embodiment of the upper conveyance section 100 shown in FIG. Even if the ejection position of the copying machine body is different due to installation, this post-processing device can be used by simply replacing the unit U.

In Fig. 6, parts common to those in Fig. 1 are given the same reference numerals. Next, the diagonal portion 200 in FIG. 1 will be explained in more detail.

The diagonal part 200 is a unit for changing the center reference of the copy paper discharged from the copying machine main body to the front end face reference in the conveyance path, and as shown in FIG. It is located in the vertical part below 103. The purpose of using the vertical conveyance path in this way is to downsize the entire apparatus and save space.

Copy paper discharged from the copying machine is guided by the switching claw 1O3 when the bin 350 is in use mode, such as sorting or stacking, and is sent to the lower diagonal receiving roller 201. The diagonal receiving roller 201 is made of EPDM1 or roller rubber, and a driven roller 214 is pressed by a temporary spring or the like to obtain a conveying force.

FIG. 7 is a side view of the diagonal roller 202 portion, and shows that the copy paper is conveyed toward the reference guide 204 by approximately 25 mm.
Two oblique rollers 202 are arranged at an angle of ~30'. This diagonal roller 202 is also the diagonal section receiving roller 201.
Similarly, it is made of EPDM or chloroprene rubber.

A ball 215 pressurized by a compression spring 218 is used as a driven roller as shown in the enlarged sectional view shown in FIG. This prevents buckling, etc. The copy paper is conveyed diagonally to the reference guide 204 by the diagonal rollers 202 and then sent to the diagonal discharge roller 203. This diagonal section discharge roller 203 ensures transportation to the next conveyance path, and is made of the same material as the diagonal section receiving roller 20l.

In FIG. 8, the driven ball case 219 and the holding member 2 are shown.
20 and the compression spring 218 pressurize the driven ball 215 in the vertical conveyance path.

The speed V in the conveying direction of the conveying rollers is as follows:
1, speed Vt of diagonal roller 202, speed Vt of diagonal discharge roller 203. However, since the velocity V2 of the diagonal roller 202 has a component in the downward conveying direction, V t = V
ta ×Cos θ, and in the example, Vffis−v
3, so V, =V3 cos θ.

Further, the relationship between the conveying forces F of the respective conveying rollers is as follows: conveying force F of the diagonal receiving roller 201 > conveying force Fz of the diagonal roller 202 #conveying force F of the diagonal discharge roller 203. In this way, only the conveyance force F of the large diagonal receiving roller 201 is increased. The purpose is to prevent this and keep the diagonal tying constant. Further, the reason why the conveyance force F of the diagonal discharge roller 203 is made equal to the conveyance force F2 of the diagonal roller 202 is to provide a margin for the diagonal conveyance distance.

Next, a method of driving each conveyance roller of the diagonal section 200 will be described.

FIG. 9 is an explanatory diagram showing the drive system of the diagonal section 200. In FIGS. 7 and 9, the driving force input from a timing pulley 210 fixed to the shaft of the diagonal section discharge roller 203 is transmitted to the diagonal section receiving roller 20 through a double-tooth timing belt 213.
The driving force is transmitted to a timing pulley 206 fixed to the shaft 1, and the diagonal receiving roller 201 obtains the driving force.

FIG. 10 is an enlarged front view of the drive transmission part, and
In Figure 0, since the axis of the diagonal roller 202 needs to be tilted diagonally, the helical gear 209 and the helical gear portion 208
The driving force is obtained from a double-tooth timing belt 213 via an idler 208 that is integrated with a timing pulley portion 208b and a timing pulley portion 208b.

Figure 1) is an explanatory diagram showing the oblique movement of the copy paper, and this figure shows the ideal movement of the copy paper when the copy paper is oriented obliquely.

That is, when the rear end of the copy paper P leaves the diagonal section receiving roller 201, the diagonal direction begins, and when the end surface hits the reference guide 204, the diagonal direction ends, and the copy paper P is straightly conveyed by the diagonal section discharge roller 203. It will be done.

FIG. 12 is a partial cross-sectional view of the reference guide 204,
In this embodiment, the reference guide 204 is fixed to the diagonal portion driving side guide plate 205 opposite to the diagonal portion driven guide plate 27 with a screw fastener.

The copy paper sent out from the diagonal section 200 is transferred to the lower conveyance guide plate 308 and the driven guide plates 309 and 310 in FIG.
and is sent to the deflection section B by conveying rollers 301, 302 and driven rollers 305, 306. The deflection section B is composed of a deflection section discharge roller 304, a driven roller 307, a driven guide plate 31), and a deflection claw 312.
12 can be individually operated by solenoids. The deflection claw 312 is opened and closed by a solenoid in accordance with designated mode conditions to guide and stack copy paper into each bin 350.

FIG. 13 is a perspective view showing the outline of the swinging device, FIG. 14 is a plan view showing the relationship between the swinging device and the bins, and FIG. 15 is a side view of the swinging device, showing each bin 350 A bin fence 450 is erected on each side edge, and
A bottle rear end rising portion 508 is provided on the other side edge that is orthogonal to the edge where the bottle fence 450 is provided.

Furthermore, a long six-part portion 51) is provided on the edge opposite to the edge where the bin fence 450 is provided.

As shown in FIG.
It is provided so as to extend over a predetermined length toward the bin fence 450 between a width C of 50 mm.

In this embodiment, the dimension a is set between 125 and 140 mm. As a result of the experiment, the a dimension is 125mm.
In the following cases, when copying a large size such as A3, a moment as shown in the top view of the bin in Figure 16 is applied, and it is found that good alignment cannot be achieved, and the a dimension is This is because it has been found that if the width is 140 mm or more, a moment as shown in the top view of the bin in Figure 17 will be applied when copying a small size such as B5 horizontal, making it impossible to achieve good alignment. For this purpose, the a dimension was set between 125 mm and 140 mm.

Further, in FIGS. 13 to 15, a swing shaft 502 having a round cross section is vertically provided so as to vertically penetrate through each elongated hole 51) provided in each bottle 350.

This swing shaft 502 is for aligning the paper stack by coming into contact with the end surface of the stack, and the surface of the swing shaft 502 is treated with high friction material rubber, sponge, sandpaper, sandblasting, or adhesive treatment. It has been subjected. Further, the swing shaft 502 is connected to a temporary spring 503a as shown in FIG. The elasticity of the copy paper 503b prevents excessive force from being applied to the copy paper stack, thereby preventing the copy paper from being scratched or wrinkled, and from overloading the motor.

FIG. 18 is an explanatory view showing the action of the copy paper and the swing shaft 50.2, and if the copy paper is curled upward, even if the swing shaft 502 attempts to align it, the action of the copy paper is explained in FIG. As shown in the situation from ■ to ■, sufficient alignment cannot be achieved if the copy paper just tries to slide upwards, so the high friction member on the surface of #g moving shaft 502 prevents the copy paper from sliding and ensures that it is firmly placed in the bin. The copy paper is delivered to the fence 450 to ensure good alignment.

Further, the upper end and the lower end of the swing shaft 502 are connected to the first
As shown in FIGS. 3 and 15, ties ξ are inserted into the recesses of the holders 504a and 504b and extend in the upper and lower regions of the bottle 350 in approximately the same direction as the extending direction of the long six part 51). } 507a and 507b are respectively arranged. Then, the holder 504
The convex portions a and 504b enter and are fixed.

Among the bobbins 509 and 510.5l2 on which the timing belts 507a and 507b are respectively hung, the pulleys 509 and 512 are respectively fixed to both ends of a drive shaft 514 that is provided to extend in the vertical direction. ing. The lower timing belt 507b is hung around a pulley 512 provided on the output shaft of the size movement motor 515.

Movement according to the size of the swing shaft 502 is performed by the size movement motor 5.
It is managed by the number of pulses given to 15.

For a certain paper size, the size movement motor 515 causes the swing shaft 502 to stop at a certain distance from the ejected copy paper (10 mm in this example), and when ejection is complete, the copy paper is at the rear end of the bin. The swing shaft 502 is controlled by pulses so as to move toward the copy paper side at the same time as it falls onto the rising portion 508, and to have a certain biting amount (5 mm in this embodiment) from the edge surface of the copy paper.

When the swing shaft 502 returns after pushing the copy paper, it temporarily stops at the width of the copy paper size and then returns to the normal position, or the speed at which the swing shaft 502 moves is varied, so that the copy paper is aligned once. This prevents the paper from separating from the bin fence 450 again due to the waist of the paper. The copy paper stack is pressed against the bin fence 450 by the swing shaft 502, and as a result, one side end surface of the copy paper stack is aligned. A method is used in which the copy paper is brought against the upright portion 508 of the bin that is orthogonal to the alignment bin fence 450 on the other side end face, and the copy paper is dropped using the slope of the bin 350 as a means for alignment. .

The bin 350 has been designed in various ways to facilitate paper alignment and stapling.

FIG. 19 is an explanatory diagram showing the state when the bin 350 is installed, and shows the bin main angle part 401 and the bin semi-angle part 402.
．． 403 is becoming more gradual.

When the bin main angle portion 401 is set to a certain predetermined angle (30" in this embodiment), as the ejected copy paper is stacked, the copy paper gradually begins to buckle. This is noticeable with thin paper. [See the copy paper buckling state (part A) shown in FIG. 20]. Bin semi-angular part 403
The buckling of the copy paper described above can be prevented by supporting the weight of the copy paper to some extent at the bin semi-angular portion 403. In this embodiment, the angle of the bin semi-angular part 403 is 15''. However, if the length of the bin main angle part 401 is short and the length of the bin semi-angular part 403 is long, the copy will be made at the bin semi-angular part 402. There are cases where the weight of the paper is supported too much and the copy paper does not fall.Therefore, the bin main angle section 4
The lengths of 01 and the bin semi-angular part 403 need to be appropriate lengths, and the bin main angle part is preferably about 300 mm, and the bin semi-angular part is about 3Q mm.

Further, the bin semi-angular portion 402 is provided as a countermeasure against face curl. The stacking situation of copy paper exhibiting face curl when the bin semi-angular part 402 is not shown in FIG. 21, and the stacking situation of copy paper exhibiting face curl when the bin semi-angular part 402 is shown in FIG. 22. A comparison of the figures shows the difference between part C in Fig. 21 and part d in Fig. 22. In part C of Figure 2I, copy Gitsu P is in bottle 3.
50, but in part C in FIG. 22, the copy P is not far away from the top of the bin 350. This shows that the shape shown in FIG. 22 allows a larger number of sheets to be stacked for the stack of copy sheets P exhibiting face curl than the shape shown in FIG. 21. In this embodiment, the bin semi-angular portion 402 has a diameter of 15@ and a length of approximately 20 mm. FIG. 23 is a front view showing the entire bottle 350;
Figure 4 is a plan view of the bin 350, and the convex portion 41) protruding from the bottom of the bin 350 is used to prevent copy paper from curling. Copy paper discharged onto the bin 350 is aligned in one direction, but copy paper with large curls may climb over the bin fence 450 provided on the side of the bin 350, making alignment difficult. The convex portion 41) is installed to prevent copy paper from curling, etc., and to ensure good alignment.

Fig. 25 is a partial cross-sectional view of the bottle 350 with a curl presser, and Fig. 26 is a -6B cross-sectional view of the bottle 350 without a curl presser. It shows step by step the state over time when the paper is aligned.

In FIG. 24, 412, 413, and 414 are handles for fixing the bottle.

FIG. 27 is a side view of the bottle 350, showing the installed state. In the same figure, 430a and 430b indicate side tents;
31a. 43lb indicates a bottle holder. Vinfence F
The bottle 350 is fixed by the bottle holder 431a on the side, and the bottle holder 43lb on the other side only supports the bottle 350 with a slight gap. By fixing the bin fence F side, you can prevent the staple position from varying. Further, a small gap provided on the side of the bottle holder 43lb allows thermal expansion of the bottle 350 to be absorbed.

In FIG. 24, reference numeral 51) is a long shaft for allowing the swing shaft 502 to move in accordance with the paper size. Bin rib 415a
is provided to improve the falling property of copy paper. When the copy paper is loaded on the bin 350, the bin 350
Bottle ribs 4 1 5 b. to prevent bending.
The parts of 4 1 5 c and 4 1 5 e near the notch for taking out the copy paper are higher than the other ribs. When the copy paper is bent, the falling property of the copy paper is significantly deteriorated. Further, when the copy paper is swung by the swiveling shaft 502 shown in FIG. 13, the alignment accuracy may not be achieved even if the sagging copy paper is swung because it has no stiffness. Rib 41 of bottle 350
5f is designed to prevent the ejected copy paper from slipping into the long six part 51) for the swing shaft.

Figure 28 shows a rib 415f near the long hole 51) for the swing shaft.
The ribs 415f protrude above and below the bin 350 to prevent the copy paper to be stacked from going under and at the same time from entering the notch of the upper bin. The arrangement of the ribs 415f is also set within 10 mm from the end face of the copy paper size, in order to reliably guide the end face of the paper that is particularly likely to enter the long six section 410.

In addition, the shape of the rib 415f on the upper side of the bin 350 in FIG. 28 has a gentle triangular shape on one side because it is ejected when the chucked copy Gibun P is stabilized and ejected as will be described later. The copy paper is ribbed 415
This is to guide the guide so that it does not get caught in f. In the vicinity of the rising portion 508 of the rear end of the bottle in FIG. 23, the ribs 415f are both low ribs 415f and 415h, as shown in FIG. 29, and gradually become higher up to the longer portion 51). This is done to ensure a large number of sheets can be loaded. Further, the bottle rib 415g in FIG. 24 follows the rib 415'' in terms of rib position. This rib is provided to improve the fall of copy paper. A cutout 416 shown in FIG. 24 is a cutout for the chucking unit to chuck the copy sheets arranged on the bin 350.

The portion 417 in FIG. 24 is depressed below the other surface of the bottle 350, as shown in the side view of a portion of the bottle 350 in FIG. 30. This section 417 is provided for taking out small size paper. If the notch 422 for taking out the copy paper is made deeper, the portion 417 becomes unnecessary, but in that case, the strength of the bin 350 will be extremely deteriorated.

The portion 417 serves to maintain the bin strength and to make it easier to take out the copy paper when taking out the small size paper. Further, 418 in FIG. 24 is a notch for the ejecting roller.

Figure 31 shows the discharge roller 304 and the rising portion 508 at the rear end of the bin.
is an explanatory diagram showing the positional relationship between the It is not located on the same plane as the C section, but protrudes from the C section in the paper ejection direction.The shape of the bin rear end rising section 508 shown in FIG. 31 has an effect on alignment accuracy in face curling. However, as the number of stacked sheets increases during face curling, the stack of copy sheets P is stacked higher than the bin rising portion 420, and "back end rising" X as shown in FIG. 32 occurs. In this embodiment, by combining the shape of the rising portion 508 at the rear end of the bottle, which is effective for face curling, and the protrusion of the discharge roller 304 into the bin 350, the alignment accuracy of face curling is improved. Protruding discharge roller 304
By scraping the copy paper with
This prevents problems such as 419 in FIG. 23 and 421 in FIG. 24 are ribs provided to reinforce the bottle. Furthermore, alignment by dropping may not provide sufficient alignment accuracy depending on the type of copy paper. In order to compensate for this, we use a yosekoro-so! 550 are provided.

5 and a round belt 336, the shifting roller 333 is driven in conjunction with the round belt 336. The driving pulley 334 and the driven pulley 335 are lO
By shifting the copy paper diagonally, the shifting roller 333 can align both sides of the bin fence 450 and the rear edge rising portion 508 of the bin. FIG. 35 is an explanatory diagram showing the relationship between the copy paper P and the shifting roller 333, and shows the relationship between the deflection section ejection roller 304 and the driven roller 3.
The copy box P conveyed by 07 is discharged into the designated bin 350 by opening the deflection claw 312. At this time, the shifting roller 333 is 5 to 7 mm away from the bin 350, and the copy paper P is discharged above the shifting roller 333 (state of ■). The rear end of the copy paper P is 20 to 30 mm from the rising portion 508 of the rear end of the bin depending on the speed at which it is ejected.
It pops out mm. The center of the shifting roller 333 is 15 mm away from the rising portion 508 of the rear end of the bottle, and is located at a distance of 15 mm from the bottle fence 450
The copy paper P that is 20 mmllt smaller than the original one and has fallen onto the shifting roller 333 is scraped off onto the bin 350 by the shifting roller 333 . The copy P that has fallen into the bin 350 is guided by the inclination of the bin 350 to the rising part 508 at the rear end of the bin, and slips into the lower part of the shifting roller 333 (state of ■).
.

Thereafter, the swing shaft 502 is moved as described above at the timing when the rear end of the copy paper P contacts the bin rear end rising portion 508, and the copy paper P is brought into contact with the bin fence 450 to align the copy paper P. Thereafter, as shown in the front view of FIG. 36 showing the installed state of the collapsing roller device 550, by pulling the solenoid 342, the bracket 337 is pulled upward, and the bin 339 inserted into the hole 338 of FIG. 33 is raised. , the shifting roller holder 331 rotates counterclockwise about the shaft 340, and the shifting roller 333 falls onto the bottle 350. Then, by rotation of the shifting roller 333, the copy sheets are brought into alignment against the bin rear end rising portion 508 and the bin fence 450. The operating times of these swinging rollers and the shifting roller 333 are set so that they end before the next copy sheet is ejected or before it enters between the shifting roller 333 and the bin 350. The next copy paper is then aligned in the same way.

The copy paper is moved to the bin fence 45 by the shifting roller 333.
0 and the rear edge rising portion 508 of the bin. However, if the force to pull the copy paper is too strong, the copy paper P will buckle as shown in FIG. It is set so that it can transport one sheet of paper, and it will slip after it hits the top. For this reason, as shown in FIG. 38, a high friction member 333b is provided on a part of the low friction member 333a of the shifting roller 333 so as to protrude beyond the circumference of the shifting roller 333. Also, as shown in the front view of the collapsing roller 333 in Fig. 39.40, a plurality of high friction members 33
3b may be provided. Furthermore, the same effect as described above can be obtained by providing an appropriate friction member on the shifting rollers 333 and setting the roller pressure.

The copies aligned in the manner described above are taken out in the direction of the arrow X in FIG. 14 after various post-processing such as a stabilization operation, which will be described later, is executed. Since there is nothing in this take-out direction that would impede take-out, the copy paper take-out operation is easily performed.

Next, the stabilizer device 700 will be explained.

4l is a perspective view of the stabler device 700, FIG. 42 is a plan view of the stabilizer device, and FIG. 43 is a front view of the bearing portion, showing a side view of the bin 350 for stacking copy paper provided in multiple stages. A stapler device 700 is disposed at. In this stabler device 700, a stabilizer 70l and a paper pulling device 615 are attached to the upper part of a plate-shaped bracket 703 and are fixed to each other. The stapler 701 staples each sorted copy bundle stacked on each bin (not shown), and the paper pulling device 615 grips the copy paper stack on each bin. hand,
It is transported almost horizontally. The bracket 70
At the part where one end of 3 is bent upward, there is a bracket}703

Furthermore, a drive belt 717 is provided upright along the side of the bin 350 and substantially parallel to it. This drive belt 717 is sandwiched between the bracket 703a and a mounting plate 718 and fixed with screws. The drive belt 717 is stretched between pulleys 719a and 719b that are spaced apart from each other by a predetermined distance in the vertical direction. The power is then transmitted to the booster 723 via the booster +J 7 2 1 fixed to the output shaft of the drive motor 720 and the power transmission belt 722, and the drive gear 724 fixed on the same axis and the gear 725 meshed with this drive gear 724 are transmitted. Rotational driving force is transmitted to a drive boom 719a fixed to one end of the support shaft 726 through the support shafts 726 in turn. Such a driving force transmission mechanism causes the drive belt 717 to be conveyed and driven, thereby transporting the stabler 701 and the paper pulling device 6.
15 vertical transfer operations are performed.

Furthermore, a position sensor 7 is provided on the bracket 71).
27 is attached, and the position sensor 727 is provided to sandwich the bracket 716. Holes 716a for indicating positions are formed in the bracket 716 at predetermined intervals so as to correspond to the positions of the respective bottles. With such a position detection mechanism, the stabler 70
1 and the paper pulling device 615 are controlled to be stopped at the installation position of each bin.

The protrusion 728 and sensor 729 in FIG. 41 are for determining the upper limit position of the bracket 703, and when the protrusion 728 enters the sensor 729, the motor 720 stops raising it.

FIG. 44 is an explanatory diagram for making it easier to understand the movement of the stapler device 700, and will explain the movement of the copy paper P discharged onto the bin 350, the movement of the chuck section 731, and the position of the stapler 701.

The copy paper P discharged onto the bin 350 is discharged to a position as shown by 730d. Thereafter, it is placed in a position where it comes into contact with the bin fence 450 using the swinging device described above.

Then, when the copy is finished and stabilization is started,
The chuck section 620 moves from a position 620b indicated by a dashed dot line to another position 620c indicated by a dashed dotted line, closes the chuck section 620 to sandwich the copy pad P, and stops at a position 620a indicated by a solid line. With this operation, the copy box P moves to the position 730f, and a certain number of copies P are stippled on the bin 350 by the stapler 701.

Thereafter, the previous operation is reversed, and the copy paper P is returned to the position 730d. This completes the work for one bin 350, moves on to the next bin 350, and repeats the operation. The details of their operation will be explained later.

FIG. 45 is a front view of the paper pulling device 615, FIG.
Figure 47. FIG. 48 is a front view of the paper pulling device 615 in its operating state, showing a chuck section 620 that grips the stack of copy sheets P on the bin 350, and a reciprocating mechanism that reciprocates the chuck section 620 in a substantially horizontal direction. 640. In the chuck part 620, a pair of swinging levers 622 and 624 are connected to the substrate 621.
is attached so that it can swing freely, and this swing lever upper 6
22 and the lower swing lever 624 are operated by the solenoid 626, so that the upper chuck 623 and the lower chuck 625 are operated to grip the stack of copy sheets P. In the reciprocating mechanism 640, a shaft 642 for sliding the chuck part is fixed to a frame 641, a bearing 629 to which a substrate 621 is fixed is engaged with this shaft 642, and is guided by this shaft 642. The chuck portion 620 moves back and forth. Further, a timing belt 643 is provided on the frame 641 for moving the chuck section 620 toward and away from the copy paper stack P.
is provided. The chuck section 620 and the timing belt 643 are fixed by an arm section 621a of a substrate 621. Tying belt 643 (pulleys 644, 645 are fixed at both ends of D, one pulley 64
4 is attached to a stepping motor 646. The output of the stepping motor 646 causes the pulley 644 to
rotates, and the timing belt 643 moves. As the timing belt 643 moves, the chuck part 6 fixed to the timing belt 643 via the arm part 621a
20 is designed to move back and forth. The frame body 641
A position sensor 650 is installed on the substrate 621, and a detection plate 630 is provided upright as a detection target.
The home position of is being detected.

In the embodiment having such a configuration, when the stable mode is started, first the drive belt 7 shown in FIG.
17, the stapler 701 and paper pulling device 6
15 are integrally moved up and down, and as shown in FIG. Position sensor 7 in the figure
Based on the signal from 27, it is stopped at a position close to a predetermined bin 350. At this time, the solenoid 626 is turned off, and therefore both swing levers 622, 624 and chucks 623, 625 are placed in an open state.

Next, the stepping motor 646 rotates a predetermined amount to move the timing belt 643 and move the chuck section 620 forward toward the stack of copy sheets P.

By changing the rotational speed of the stepping motor 646, the speed at which the chuck portion 620 moves is controlled. In the case of this embodiment, the chuck unit 620 grips the aligned stack of copy sheets P with the chucks 623 and 625, and gradually accelerates at the start when moving back to the stapling position, and gradually decelerates when it stops. This prevents aligned copy paper from becoming inconsistent due to inertia during acceleration and deceleration. When moving the same distance within the same time, uniform acceleration motion has the smallest maximum value of inertia, so in this example,
It accelerates and decelerates with constant acceleration.

And the chucks 623 and 625 are large enough to grip the copy paper stack P! When it is moved to (Fig. 47), it is stopped there and at the same time, the solenoid 626 is turned on. By turning on the solenoid 626, the chucks 623, 625 are closed as shown in FIG.
25 grips the edge portion of the copy paper bundle P. The movement at this time will be explained in more detail. That is, when the solenoid 62G is turned on, the lever 628 is pulled by the spring 627 hooked to the solenoid 626, and the lever 62G is turned on.
The upper lever 622 engaged with the upper lever 622 rotates counterclockwise about the fulcrum 622a, and the upper chuck 623 lowers. Further, the lower lever 624 has a contact portion 624c with the upper lever 622.
The movement of the upper lever 622 is transmitted, the lever 624 rotates clockwise around the shaft 624a, the lower chuck 625 is raised, and the upper and lower chucks 623, 62
5 grips the copy Gizuka P. The amount of movement of the upper chuck 623 and lower chuck 625 from their normal positions is determined by the lever 628.
It is determined by the rotational fulcrum, the force point, and the length of the point of application. In the case of this embodiment, when the moving amount of the chuck is expressed as a ratio, as shown in FIG.
The distance between and the fulcrum 622a is 92 mm, and the distance between the force point 622C and the rotation fulcrum 623a is 33 mm, so 9
2:33'=12.79:1, and the chuck bottom is 625
In this case, the distance between the point of action 624b and the axis 624a is 26 m.
m, the distance between the force point 624C and the shaft 624a is 33 mm, so the ratio of the amount of movement is 26:33''=.0.79
:1, and the ratio of the moving distances of the upper chuck 623 and the lower chuck 625 is 2. 7 9: 0. 7 9 = 3
．． The ratio is 53:1. That is, the upper chuck 623 is 3.5
If it moves downward, the lower chuck 625 will move upward by 1. Also, the chuck force between the upper chuck 623 and the lower chuck 625 is controlled by the spring 6 attached to the solenoid 626.
Determined by the power of 27. Upper chuck 623 and lower chuck 62
The spring 627 becomes longer and the chucking force increases as the number of sheets of the copy sheet P to be held between the 5's increases, thereby eliminating problems such as misalignment due to insufficient chucking force. Furthermore, if the chucks 623 and 625 grip only one corner of the copy paper, the fourth
As shown in FIG. 9, a moment is applied to the copy paper P, causing the copy paper P to tilt on the bin 350, causing the stapling position to vary, so the chucks 623 and 625 are separated as shown in FIG. The copy machine P may be gripped at a plurality of locations to prevent the copy machine P from tilting even if a moment of inertia is applied. Next, by reversing the stepping motor 646, the chuck section 620 is moved back to its original position as shown in FIG. , and is pulled toward the stapler 701 side. When the edge portion of the copy paper stack P is transported to a stable position, it is stopped there. Thereafter, the stapler 701 staples the edge portion of the copy paper bundle P.

When the stapling operation is completed, the stapling motor 64
6 rotates in the normal direction, the chuck unit 620 moves forward, and after returning the stable copy paper P onto the bin 350, the solenoid 626 is turned off. As a result, the upper chuck 623 and lower chuck 625, which have been closed until now, will be opened. Thereafter, the chuck portion 620 is retracted to a predetermined position by reversing the rotation of the stepping motor 64G. Thereafter, the stabler 701 and paper pulling device 615 move to the next bin 35.
0, where a stapling operation similar to that described above is repeatedly performed.

51 is a front view of the paper alignment mechanism, and FIGS. 52 and 53 are front views of the paper alignment mechanism in an operating state. As shown in FIG. A bin fence 450 for aligning the copy paper stack P is provided at the opposing edge portion so as to rise from the bin 350. This bottle fence 4
The lower edge portion of 50 is rotatably attached to a support shaft 451 provided along the lower surface of the bin 350, so that the bin fence 450 can be tilted to the open position shown in FIG. It has become.

Both end portions of the support shaft 451 are rotatably supported by bearing pieces 456 that are shaped downwardly at both end edge portions of the bottle 350. Further, a coiled spring 452 is attached to the support shaft 451.

Both winding end portions of the winding spring 452 are in contact with and locked against the bottom side of the bottle 350 and the back side of the bottle fence 450, respectively, and the rotational force of the winding spring 452 causes the bottle fence 450 to move upward in the rising direction. It is beginning to receive force.

Furthermore, the bin fence 450 is opened as the stapler 701 moves up and down via a fence tilting member. This fence tilting member is a fence movable temporary 453 attached to the support shaft 451 side.
and the fence release Fi installed on the stapler 701 side.
It consists of 4 5 4.

A portion of the fence movable plate 453 is inserted into a fan-shaped hole opened in one piece 450a of the bin fence 450,
When the fence movable plate 453 is rotated downward, the lower part of the fan-shaped hole in one piece 450a of the bottle fence 450 is brought into contact with the bottle fence 450, and as a result, the bottle fence 450 is shifted to the fence movable plate 453 and is knocked down. It is now possible to Further, when the fence movable plate 453 is rotated upward, it is rotated so as to be separated from the bin fence 450 side without contacting the fence movable plate 453.
53 will be freely rotated.

Further, the rollers 454a of the fence release plate 454 extend to a position where they come into contact with the fence movable plate 453, and when the stapler 701 moves up and down, the fence movable plate 454
The fence movable plate 453 is rotated by contacting the fence movable plate 453.

In the apparatus in this embodiment, when a sorting operation is first performed, the bin fence 450 is maintained in the upright position by the rotational force of a coiled spring 452, as shown in FIG. As a result, the edge of the copy sheet P discharged onto the bin 350 comes into contact with the bin fence 450, and paper alignment is performed.

When this sorting operation is completed, the above-mentioned stapler 70
1 begins to descend, and the roller 454a of the fence release plate 454 on the stabler 701 side comes into contact with the fence movable plate 453 on the bin 350 side. And fence movable board 453
is rotated to the lower position as shown in FIG. As the movable fence vi453 rotates, the bin fence 450 is tilted against the rotational force of the coiled spring 452, thereby opening the bin 350. At this time, the bottle fence 450 and the movable fence plate 453 are pushed down to a position below the position A of the bottle 350, which is indicated by the dashed line in FIG. In this state, the stapling operation as described in the above embodiment is executed.

The stable operation is completed and the copy paper stack P is placed in the bin 350.
At the same time as the stabilizer 701 is returned to its original position, the stabilizer 701 is moved downward toward the next bin 350. Then, by the downward movement of the stapler 701, the fence release plate 4 is
54 is removed from the fence movable plate 453 side, the bottle fence 450 is raised by the rotational force of the coiled spring 452 and returned to its original position. Such opening and stabilizing operations of the bins 350 are performed when the bins 350 are sorted.
This is done for all 0's.

When stapling is performed on all copy paper stacks P,
The stapler 701 is raised and returned to the highest home position. The home position is located further above the first bin 350 located at the top. When the stapler 701 returns, the stapler 701
01 side fence solution #. lt7454 comes into contact with the fence movable plate 453 from below, but in this case, the fence movable plate 453 is rotated upward in an idling state as shown in FIG. 53, so that the pin fence 450 It is not rotated in any way. Stabra 70
When the fence release plate 454 of the stapler 701 is separated from the fence movable plate 453 by the upward movement of step 1, the fence movable plate 453 is returned to its original position as shown in FIG. 51 by its own weight.

FIG. 54 is a front view showing another embodiment of the alignment mechanism, in which an elastic body 455 that receives a fence movable plate 453 is installed on the bin fence 450 side. In such an embodiment, when the stabler 701 returns, if the fence movable plate 453 is rotated upward in an idling state, the fence movable plate 453 comes into contact with the elastic body 455 side and is received. The movable fence plate 453 is returned to its original position by the deflection repulsive force of the elastic body 455. Fig. 55 is a perspective view showing another embodiment of the bin fence 450, Fig. 56 is a plan view of the embodiment of Fig. 55, Fig. 57 is a perspective view of the same embodiment in an operating state, and Fig. 58 is the same. 55 and 56, the fence 460 is pressed against each bin 350 and all bins 350 are
I try to use a single board for the alignment. The fence 460 is rotatably mounted at rotational supports 460a and 460b at the upper and lower ends. The rotation fulcrum 460b has a gear 460C, a gear 461 is engaged with the gear 460c, and the gear is driven by a drive motor 462.

When aligning the copy paper, the fence 460
As shown in FIG. 6, it faces the bin 350 and performs the alignment. When all sorting is completed and stipple is performed, the fence 450 is rotated approximately 90'' as shown in Figures 57 and 58.
It is now possible to move away from the bin 350 and move the copy P to the stable position. FIG. 59 is a block diagram of the control system in this embodiment, and this control system is centered around the CPU 800 as the control means.

There are WAIT signals, BUSY signals, mode end signals, staple count signals, abnormal signals, etc.

The operation and control of the embodiment of the present invention will be described below with reference to flowcharts.

FIG. 60 is a flowchart of the overall operation of this embodiment. First, a mode signal sent from the copying machine is received (step 1-1), and after copying is started, a size signal is received (step 1-2). Subsequently, a sorter start signal is received (step 1-3). Upon reception of this, the mode signal turns on the sorter motor (at the time of sorting or stacking) or the Bruch motor (at the time of Bruf. interrupt).

First, the blue mode (step 1-4) will be explained. After turning on the Bruch motor 1) 7 in Fig. 1 (step 1-5), turning on the switching SOL 107 in Fig. 3 (step 1-6), and receiving the paper discharge signal (step 1-7). , carried in from the entrance guide 102 (step 1-8
) is ejected to the upper bruft tray 1) 6 (step 1-9>. After ejecting the copy paper,
A discharge signal is sent to the copying machine (step 1-10) to notify that the copy paper that has been carried in has been discharged. below,
Repeat this operation until the copy is completed (Step 1-
1)). At this time, copy paper jam detection (not shown in the flowchart) is naturally performed. After copying,
Switching SQL 1 0 7 and Bruch motor 1) 7 are turned off (step 1-12), and the process waits until the next copy operation.

Next, sort and stack modes will be explained.

After turning on the sorter motor 313 in FIG.
-13) Determine whether swing is possible or not based on the size signal, etc., and if swing is possible (step 1-14), move the swing shaft 502 in Fig. 13 to the position corresponding to the received size signal. (Step 1-15). Next, when the copy paper is ejected from the copying machine, the copying machine transmits a destination bin instruction signal and an ejection signal for the copy paper to be ejected (step 1-16). The destination bin 350 is determined by receiving the discharge signal (step 1-17). Next, copy paper is carried in from the copying machine (step 1-18).
). After loading, the entrance sensor is turned on, and the deflection solenoid (S Q L) determined by the discharge destination bin instruction signal is turned on (
Step 1-19), guide the copy paper to the bin 350.

When the copy paper is ejected (step 1-20), an ejection signal is sent to the copying machine (step 1-21), and the ejection signal is sent to the bin 350.
Notifies the copying machine that the paper has been properly ejected to the top. Based on this signal, the copying machine determines the next destination and the destination after the jam has been covered. Copy paper is ejected to the bin 350.
After an appropriate amount of time has elapsed for the copy paper to settle down (e.g. 300 ms; step 1-22),
Turn on the size movement motor 515 in FIG.
By moving 02 (step 1-23), alignment in the direction perpendicular (horizontal) to the discharge direction is performed. The timing for moving the swing shaft 502 is determined based on the detection of the trailing edge of the copy paper by the ejection sensors 322 and 324 (step 1-24). After the above-mentioned swinging operation is completed, copies that rarely reach the end of the bin 350 or the bin fence 450 because the copy paper is curled, has scratches or folds on the surface, or is charged with a large amount of static electricity. There's paper. Work is done to forcibly bring it to the edge.

Therefore, at the same time as the swing shaft 502 moves, the SOL
342 is turned on (Step 1-25), the rotating roller 333 comes into contact with the top surface of the paper, suppresses the curl, and forcibly moves the paper toward the edge (for a certain period of time -200 ms; Step 1-26).

This shifting roller 333 is attached to each bin 350, and all of them are lowered at once by the shifting SOL 342. After completing this operation, turn off the shift SOL 342 (step 1-
27) Do.

The above operations are performed every time a copy is ejected, and sorting is performed (step 1-28). When the sorting is completed in this manner, the sorter motor 313 is turned off (step 1-29) and the stapling operation is performed. Upon receiving the stabilization start signal (step l-30), the stapler device 700 operates (step 1-31),
Stabilizes the loaded copy paper. When the stapling operation is completed (step 1-32), the stapler device 700 and the swing shaft 502 move to the home position (step 1-33).

FIG. 61 is a flowchart explaining the alignment operation;
Figures 2 (al to dl are explanatory diagrams showing the operation of the swing shaft, and the swing shaft 502 is located at a position based on the size signal as described above (in this embodiment, the swing shaft from which the copy paper is ejected). 50
It was stopped in advance at a position 1Qmm from the end face of the two examples.

This is a position where the ejected copy paper P will not hit the swing shaft and cause jamming or paper breakage [Figure 62 (a)
))． The copy paper is ejected, and after 300 ms, it is stuck in the swinging motion and the paper is aligned.

First, Sabaz moving motor 515 (stepping motor)
so that the swing axis 502 approaches the paper by 25 mm, that is, C
I/O the phase signal by the number of pulses equivalent to 15 mm in the CW direction.
It is output from the O port 803 and driven by the constant voltage driver 81) to move the swing shaft 502 [Step 2
-l; Fig. 62(b)]. The speed at this time is 500p
ps, and any speed that does not cause defects such as wrinkles, scratches, and creases on the copy paper is sufficient. The copy P discharged onto the bin 350 by this operation is transferred to the bin fence 4.
50 due to excessive feed. This excessive pressing is to prevent variations in the length of the copy paper P and to achieve reliable shifting, and may be any suitable value other than 5 mm.

After pressing the copy paper P, it stops once (50 ms in this embodiment; step 2-2). This is copy paper P
This function is used to stabilize the size movement motor 515 and to switch forward/reverse rotation of the size movement motor 515, and is not particularly necessary and does not require waiting. Thereafter, the swing shaft 502 is moved 5 mm away from the paper, that is, in the CW direction by the number of pulses equivalent to 5 mm [Step 2-3; Fig. 62 (C]]. The speed at this time is 300 pps, and the copy It is sufficient that the speed is slower than the speed at which the paper P returns due to over-shifting, and the speed is such that the return due to the stiffness of the copy paper P does not disturb the alignment once it has been aligned.Also, by returning 5 mm and stopping, the paper width will match the paper width. The iW moving axis 502 plays the role of a bin fence on the opposite side and is further stopped for 5 9 ms (step 2-4), so that the copying axis P is reliably aligned. 502 returns to the initial position in preparation for ejecting the next copy paper [Step 2-5: 6th
1 (d)) and stops (Step 2-6>. The speed at this time should be at least the speed that is sufficient to eject the next copy paper. By the way, the number of stacked copy papers in the bin 350 can be stabilized. After the number of sheets (30 sheets in this embodiment) is exceeded, stabilization of the ejected copy paper is prohibited, the swinging that interferes with sorting is stopped, and the swing shaft 502 is retracted to the home position. I'm letting you do it.

This operation will be explained below with reference to the flowchart in FIG. 63.

The number of copy sheets stacked on the bin 350 is detected (step 3-2) by counting when the copy sheets are discharged to the first bin (step 3-1). When it is determined that the discharge count value of the first bin exceeds the number of sheets that can be stippled (step 33), the swinging operation and the rolling motion are stopped (step 3-4), and the swinging shaft 502 is retracted to the home position. (Step 3-5) After that, paper alignment is not performed for the ejected copy paper. At the same time, the previously ejected copy paper is also prohibited from being stable (step 3-6).

The stapling operation will be explained according to the flowchart of FIG. 64 (al to FIG. 64+1). After sorting is completed, if there is copy paper on the bin, the copying machine transmits a stable start signal, receives this signal, sets the sequence counter to O (step 4-1), and starts operation. . First, the stapler device 700 at the home position is moved to the first bin to be stabilized (
Step 4-2). After the Stabler device 700 moves to the first bin, the operation proceeds based on the value of the stapling operation sequence counter shown in FIG. The value of the sequence counter is set from O to 1 (step 4-3). When the value of the stable sequence counter is 1 (step 4-4), the chuck motor (stepping motor ) 646 (Step 4-
5) Advance the chuck section 620 in FIG. 45. Since the motor is a stepping motor, the amount of movement is determined by the number of pulses corresponding to the amount of movement (step 4-6). Also, the amount of movement at this time is from the home position of the chuck unit 620 (the position where the chuck home sensor 650 is on) to the position where the chuck unit 620 moves to the bin 35.
This is the amount that can be used to chuck a copy of Gishu on 0. When the chuck part 620 finishes moving forward (step 4-7)
, sets the stable sequence counter to 2 (step 4-8), and proceeds to the next operation.

When the value of the staple sequence counter is 2, the 64th
As shown in the figure (Cl), the chuck SOL 626 is turned on (step 4-9), thereby chucking the stack of copy sheets.Then, the stipple sequence counter is set to 3 (step 4-10), and the next operation is started. Proceed. When the value of the stable sequence counter is 3, the 64th
As shown in figure (d), start the timer (step 4).
-1)) state to 0. Hold for 2 seconds, and after 0.2 seconds (
Step 4-12), the timer is stopped (step 4-13), the stable sequence counter is set to 4 (step 4-14), and the operation proceeds to the next step.

When the value of the stable sequence counter is 4, the chuck motor 646 is turned on (Ill) as shown in Fig. 64 (Ill).
Step 4-15), moving the chuck section 620 to the home position. The chuck home sensor 650, which detects the completion of the home movement of the chuck part 620, is turned on (step 4-16), the movement of the chuck part 620 to the home position is completed, and the chuck motor 646 is stopped (step 4-17). The staple sequence counter is then set to 5 (step 4-18), and the operation proceeds to the next step. At this time, the speed of the chuck motor 646 is uniformly accelerated so that the chucked copies do not shift. In this example, it starts from 600pps and increases to 2000pps.
We are slowing it down to pps.

When the value of the stable sequence counter is 5, the 64th
As shown in figure (f), check the output of the paper presence sensor 675 in Fig. 48 (step 4-19), turn on the stable motor if there is paper (step 4-20), and bind the copy paper. perform an action. The end of the stapling operation is detected by the staple home sensor 650 (step 4-21), the stapling operation is ended (step 4-22), and 6 is set in the stable sequence counter (step 4-23).
, proceed to the next operation. When the output of the paper presence/absence sensor 675 is GIN, the chuck S that performs the stable binding operation
Turn off the OL626 (step 4-24) and set the stable sequence counter to 8 (step 4-25).
), move on to the next operation.

When the value of the staple sequence counter is 6 (step 4-26), the chuck motor 646 is moved forward again in order to return the stapled copy to the bin 350 as shown in FIG. 64 (step 4-26). 27).After sending the set pulse number (step 4-28), the chuck motor 646 is stopped (step 4-29), the chuck SOL 626 is turned off (step 4-30), and the chuck arm 622, 624 is released.

After that, the timer is started (step 4-31), and after checking the chuck SQL626 response time of 0.2 seconds (step 4-32), the timer is stopped (step 4-33).
), sets the stable sequence counter to 7 (step 4-34), and moves on to the next operation.

When the value of the stable sequence counter is 7, the 64th
As shown in Figure (h), the chuck part 620 is moved to the extent that it does not touch the bottle 350 in order to move to the lower bottle. This can shorten the time from chucking to completing stabilization per bin, increasing system productivity. That is, the chuck motor 646 is started (step 4-35) and moved backward by the set pulse (step 4-35).
-36), and after the backward movement, the chuck motor 646 is stopped (step 4-37). Thereafter, the stable sequence counter is set to 8 (step 4-38). When the stapling is completed, that is, when the stapling sequence counter is 8, the vertical movement motor 720 is turned on (step 4-39) to raise the stapler device 700, as shown in FIG. 64 (1). And upper and lower home sensors 72
9 is turned on (step 4-40), the vertical movement motor 720 is turned off (step 4-41). Thereafter, the stable sea record counter is set to 0 (step 4-42).

The operations of the stable sequence counters 0 to 8 described above are performed until the stapling is completed.

Thereafter, the size movement motor 515 is turned on, and when the size home sensor 501 is turned on, the size movement motor 515 is turned off. The home movement of the stapling device 700 and the movement of the swing shaft 502 may be performed simultaneously, or the order may be reversed to that of this embodiment.

Next, the function of slowing up and slowing down vertical movement will be explained. This function gradually increases the movement speed at the start of vertical movement, moves at a constant speed when it reaches the set value, and when the vertical movement stops, gradually decreases the movement speed from before the bin position to stop, and then increases the movement speed to the set value. When it reaches this point, it moves at a constant speed and stops at the stop bin position.

FIG. 65 is a flowchart illustrating slow-up/slow-down, and in a subroutine called every lms, if the slow-up operation has not been completed after the vertical movement motor 720 is turned on (step 5-1), (
Step 5-2), the slow-up counter increments by 1 for each subroutine call (step 5-3)
. Set the speed to gradually increase based on the value of the slow-up counter (step 5-4).
CT the speed data from the speed data group within 01
C804 (step 5-5). This CTC
A frequency based on the set speed data is generated from 804 and sent to the phase signal generation section 813 in FIG. The phase signal is sent from the phase signal generation section 813 to the constant current driver 81
2, and the vertical movement motor 720 operates at a rotation speed corresponding to the speed data.

When the slow-up counter reaches a certain set value (step 5-6), the slow-up ends (step 5-6).
7) The vertical movement motor 720 then operates at a constant rotation speed.

After a certain period of time, the slowdown operation starts (step 5-
8) The slowdown counter counts up by one for each subroutine call (step 5-9). Set the speed to gradually decrease based on the value of the slowdown counter (step 5-10).
CT the speed data from the speed data group in 1.
C804 (step 5-1)). This CT
The C804 generates a frequency based on the set speed data and sends it to the phase signal generation section 813. A phase signal is sent from the phase signal generator 813 to the constant current driver 812, and the vertical movement motor 720 operates at a rotation speed corresponding to the speed data.

When the slowdown counter reaches a certain set value (step 5-12), the slowdown ends (step 5-12).
-13) The vertical movement motor 720 then operates at a constant rotation speed. When the stapler reaches the bin to be stopped,
The vertical movement motor 720 is turned off and stopped, and the slow-up counter and slow-down counter are cleared (steps 5-14).
