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 main conveyance section 100, and FIG. 4 (
al is a side view showing details of the main conveyance section 100, in which the copy paper discharged from the copying machine main body is guided by guide plates 101, 1.
02 and transported to the switching claw 103. This switching pawl 103 is connected to a switching solenoid (SQL) 107 via a link 104.1.05.106, and when the solenoid 107 is turned off, copy paper is transferred to the diagonal section 200 provided below the main conveyance section 100. Again, solenoid 107
When turned on, each subject is sent into the subject sending section 100.

When the solenoid 107 is turned on, the switching pawl 103 operates, and the copy paper guided into the subject feeding section 100 is moved to the switching pawl 1.
03 is sent to a conveying roller 108 provided immediately above the roller. The conveying roller 108 is made of EPDM or chloroprene rubber, and is moved by the driven roller 10 under the action of a plate 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 110, and is conveyed to the discharge roller 111, and is discharged to the brew tray 116.

The above-mentioned driven roller 109 and switching claw 103 are attached to the kite plate 110, and as shown in the plan view of the guide plate 110 portion shown in FIG.
It is designed to rotate and open around the center. By rotating and opening the guide plate 110, the switching pawl 103 or the driven roller 109 is opened, making it easier to handle paper jams and the like in this area.

The copy paper conveyed by three vertical rows of conveying rollers 108 and driven rollers 109 passes through guide plate 1. O], , 114, and is transported to the discharge roller 111. The material of the discharge roller 111 is also EPDM like the conveyance roller 108.
Alternatively, the driven roller 115 of the discharge roller 111 is also made of chloroprene rubber.
Similar to 09, it is pressed by a leaf spring or the like and has a discharging force.

The copy paper that has been conveyed to the ejection roller 111 is ejected to the brochure tray section 116 shown in FIG. 1 by the action of the ejection roller 111 and the driven roller 115. As shown in FIG. 1, the proof tray section 116 is located closer to the main body than the sorting bin 350. This means that the copy paper can be moved 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 copy paper. It has also been shortened. Furthermore, since this bruft tray portion 116 also serves as a part of the upper cover, which is an exterior body, there is no need to provide a dedicated bruft tray.

FIG. 5 is an explanatory diagram showing the drive system of the main conveyance section 100, and the main conveyance section 100 is independently provided with a motor 117.
The driving force is transmitted via gears 130 and 131 to timing pulleys 119 and 120 fixed to the shafts of the conveyance roller 1°8 and the discharge roller 111, respectively, by the Thai puffer belt 118, thereby driving the conveyance roller 108 and the discharge roller 111. This is the configuration that does this.

Further, a feature of the main 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 brochure tray section 116 is used, the copy paper is conveyed by operating the drive motor 117 of the main conveyance section 100 and the solenoid 107, and in the mode in which the bin 350 is used, the drive motor 117 of the main conveyance section 100 is operated. , 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 main transport section 100 is unitized and can be easily attached and detached. For example, as shown in the front view of another embodiment of the main transport section 100 not shown in FIG. Even if the ejection position of the copying machine body is different by installing the unit U, this post-processing device can be used simply by replacing the unit U.

In FIG. 6, common members with those in FIG. 1 are given common symbols.

Next, the diagonal portion 200 in FIG. 1 will be explained in more detail.

The diagonal unit 200 is a unit for changing the center reference of the copy paper discharged from the copying machine main body to the front end reference in the transport path, and as shown in FIG. It is located at a vertical portion below the switching claw 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 103 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 EPDM or coloroprene rubber, and a driven roller 214 is pressed by a leaf 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° to 30°. The diagonal rollers 202 are also made of EPDM or chloroprene rubber, like the diagonal portion receiving rollers 201.

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. The diagonal discharge rollers 203 ensure transport to the next conveyance path, and are made of the same material as the diagonal receiving rollers 201.

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

The speed V in the conveying direction of the conveying roller is determined by the diagonal receiving roller 20.
1 speed V+ #Speed of diagonal roller 202 V2 <speed V of diagonal section discharge roller 203. However, since the speed V2 of the diagonal roller 202 has a component in the downward conveying direction, V2 = V2aX
cos θ, and since Via=V3 in the example, V
2-V3 cos θ.

Furthermore, the relationship 1 between the conveying force F of each conveying roller is as follows: conveying force Fl of the diagonal section receiving roller 201 > diagonal roller 20
The conveying force F2 of 2 # is the conveying force Fl of the diagonal section discharge roller 203. Increasing only the conveyance force Fl of the diagonal section receiving roller 201 in this way prevents the copy paper from being slanted even if the leading edge of the copy paper is fed into the diagonal section receiving roller 202 until the trailing edge passes through the diagonal section receiving roller 201. The purpose is to keep the diagonal timing constant. In addition, the conveying force F3 of the oblique discharge roller 203
The reason why is made equal to the conveyance force F2 of the diagonal rollers 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 manually applied from the timing boob IJ 210 fixed to the shaft of the diagonal section discharge roller 2゜3 is fixed to the shaft of the diagonal section receiving roller 201 via a double-tooth timing belt 213. The received roller 201 receives the driving force.

FIG. 10 is an enlarged front view of the drive transmission part. 2 In FIG. 7.10, since the shaft of the diagonal roller 202 needs to be tilted diagonally, the helical gear 209 and the helical gear part 208a are integrated with the timing pulley part 208b. The double-tooth tie blower belt 21 is connected to the idler 20B.
The driving force is obtained from 3.

FIG. 11 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 217 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 3013 4 302 and driven rollers 305 and 306. The deflection section B is composed of a deflection section discharge roller 304, a driven roller 307, a driven guide plate 311, and a deflection claw 312, and each deflection claw 312 can be individually operated by a solenoid. The deflection claw 312 is opened and closed by a solenoid according to specified mode conditions to guide and stack one sheet of paper into each bin 350.

FIG. 13 is a perspective view showing the outline of the swinging device, FIG. 4 is a plan view showing the relationship between the swinging device and the bottles, and FIG. A bottle fence 450 is erected on each side edge, and a bottle rear end rising portion 508 is erected on the other side edge that is orthogonal to the edge where the bottle fence 450 is provided. There is.

Further, an elongated hole portion 511 is provided at the edge opposite to the edge where the bin fence 450 is provided.

As shown in FIG. 14, this elongated hole portion 511 has a distance a from the bottle rear end rising portion 508 equal to the distance from the bottle fence 450 and the bottle rear end rising portion 508.
The fence is provided to extend a predetermined length toward the fence 450 between a width C of 50 mm and a width C of 50 mm.

In this embodiment, the eight dimensions are set between 125 and 140 mm. As a result of this experiment, the 8th dimension is 125mm
In the following case, when copy paper P of large size such as A3 is used, a moment as shown in the top view of the bin in Figure 16 is applied, and it is found that good shifting cannot be performed. 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 copy paper P of small size such as B5 landscape is used, making it impossible to achieve good alignment. For this purpose, the 8 dimensions were between 125 mm and 140 mm.

Further, in FIGS. 13 to 15, a swing shaft 502 having a round cross section is erected so as not to penetrate vertically into each elongated hole 511 provided in each bottle 350.

This swing shaft 502 is for aligning the sheet stack 5 6 by coming into contact with the end surface of the sheet stack 5 6 .
The surface of the swing shaft 502 is made of high friction rubber.

Sponge, sandpaper, sandblasting and adhesive treatments are applied. In addition, as shown in FIG. 15, the swing shaft 502 is designed to prevent excessive force from being applied to the stack of copy paper due to the elasticity of leaf springs 503a and 503b, which may damage or wrinkle the copy paper or overload the motor. It has become.

FIG. 18 is an explanatory diagram showing the action of the copy paper and the swing shaft 502. When the copy paper curls upward, the swing shaft 502
Even if you try to align it with 02, it will just slip and try to go up like the situation from ■ to ■ in the explanatory diagram of FIG. The friction member suppresses the slippage of the copy paper, ensures that the copy paper reaches the bin fence 450, and ensures 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, there are people in the recesses of the holders 504a and 504b, and in the upper and lower regions of the bottle 350 there are timing holes extending in substantially the same direction as the elongated hole 511. Belts 507a and 507b are arranged, respectively. Then, the holder 504
2. The convex part of 504b enters and is fixed.

Of the pulleys 509, 510, and 512 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. There is. 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 axis 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 swing shaft 502 is stopped by the size movement motor 515 at a fixed distance from the ejected copy paper (10 mm in this embodiment). At the same time when the ejection is completed and the copy paper falls to the rear edge rising portion 508 of the bin, the swing shaft 50782 is moved toward the copy desk side to obtain a certain biting angle (5 mm in this example) from the edge of the copy paper. It is managed by pulses as shown in FIG.

When the swing shaft 502 finishes pressing the copy paper and returns, it 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 can be varied to ensure that the copies are aligned once. The paper is prevented from being separated from the bin fence 450 again due to its stiffness.

The copy paper stack is pressed against the bin fence 450 by the swing shaft 502, and as a result, the position of one example of the end face 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, which is orthogonal to the alignment bin fence 450 on the other side end surface, and the copy paper is dropped by utilizing the slope of the bin 350 as one means of 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 are moderate.

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 on thin paper [see copy paper buckling condition G (portion A) shown in FIG. 20]. Bin semi-angle 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 quasi-angle portion 403 is 15°. However, if the length of the bin main angle part 401 is short and the length of the bin semi-angle part 403 is long, the weight of the copy paper may be supported too much by the bin semi-angle part 402, and the copy paper may not fall. do. Therefore, the bottle main angle part 4
01 and the bottle semi-angular part 403 need to be appropriate lengths, preferably about 300 mm for the main bin angle part and about 80 mm for the bin semi-angular part.

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-angle part 402 is not shown in FIG. Comparing the stack status, part C in Fig. 21 and part C in Fig. 22
The difference in section d of the figure is shown. At section C in FIG. 21, the copy paper stack P is floating away from the top of the bin 350, but at section C in FIG. 22, the copy paper stack P is not far away from the top of the bin 350. This is because the shape of copy paper P exhibits more face curl in the shape shown in FIG. 22 than in the shape shown in FIG.
This shows that you can stack a larger number of cards. In this embodiment, the bin quasi-angular portion 4°2 is 156 and the length is about 20 mm.

FIG. 23 is a front view showing the entire bin 350, and FIG. 24 is a plan view of the bin 350. A convex portion 411 protruding from the bottom of the bin 350 is used to suppress curling of copy paper. Copy paper discharged onto the bin 350 is aligned in one direction, but highly curled coffee paper may climb over the bin fence 450 provided on the side of the bin 350, making alignment difficult. The convex portion 411 is installed to prevent copy paper from curling, etc., and to enable good alignment.

FIG. 25 is a partial sectional view of a bottle 350 with a curling press, and FIG. 26 is a partial sectional view of a bottle 350 without a curling press. 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, 430
b indicates a side plate, and 431a and 431b indicate a bottle holder. The bottle holder on the side of the bottle fence F holds the bottle 3 on the stand 431a.
50 is fixed, and the bottle holder on the other side is the stand 431b that holds the bottle 3.
It is only supported with a small gap of 50 mm. By fixing the bin fence F side, the staple position can be prevented from varying. Also, the bottle holder is on stand 431b.
A small gap on the sides allows thermal expansion of the bottle 350 to be accommodated.

In FIG. 24, reference numeral 410 indicates a long axis for moving the swing shaft in accordance with the paper size 1 2 . Binrib 415
A is provided to improve the falling property of the copy paper. The bin ribs 415b, 4.15c and 415e have cutouts 422 for taking out the copy paper so that the copy paper can be removed from the bin 35.
In order to prevent the bin 350 from bending when stacked on the 0, the portions of the bottle ribs 415b, 415c, and 415e near the notch for taking out the copy paper are higher than the height of 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. The rib 415r of the bin 350 allows the ejected copy paper to pass through the elongated hole 410 for the swing shaft.
It has been taken into consideration to prevent people from sneaking into the area.

FIG. 28 is a cross-sectional view of a part of the rib 415f near the elongated hole 410 for the swing shaft, and the rib 415r protrudes above and below the bin 350 to prevent copy paper to be stacked from slipping underneath. This prevents it from entering the notch in the upper bin at the same time.

The arrangement of the ribs 415f is also 1 from the edge of the copy paper size.
It is set near 0mm, especially the long six part 41.
Consideration has been given to ensuring that the edge surface of the paper, which tends to become zero, is guided reliably.

In addition, the shape of the rib 415f on the upper side of the bin 350 in FIG. 28 forms a gentle triangular shape on one side because it is ejected when the chucked copy paper stack P is stapled and ejected as 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 bottle rising portion 420 in FIG. 23, the ribs 415f are both low ribs 415f and 415h, as shown in FIG. 29, and are gradually raised to the elongated hole portion 410. This is done to ensure a large number of sheets to be loaded. Further, the bottle rib 415g in FIG. 24 follows the rib 415f in terms of rib position. This rib is provided to improve the falling property of the copy paper.

The notch 416 shown in FIG.
- The holding part is a cutout part for chucking the copies 34 arranged on the bin 350.

The portion 41.7 in FIG. 24 is depressed below the other surface of the bin 350, as shown in the side view of a portion of the bin 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 paper discharge roller.

FIG. 31 is an explanatory diagram showing the positional relationship between the discharge roller 304 and the bottle upright portion 420, and a6 has a slightly larger angle than 906. Part b is a straight part,
The C section has a curved shape. The discharge roller 304 is
It is not located on the same plane as the section C, but protrudes further in the paper ejection direction than the section C. Bottle rising portion 4 shown in Fig. 31
Shape No. 20 shows an effect on alignment accuracy in face curl. However, as the number of stacked sheets increases due to face curl, the stack of copy sheets P is stacked higher than the bin upright portion 420, resulting in "trailing edge rising" X as shown in FIG. 32. In this example,
By combining the shape of the bin upright portion 420, which is effective against face curl, and the protrusion of the discharge roller 304 into the bin 350, it is possible to improve the alignment accuracy of face curl, and the protruding discharge roller 304 can remove copy paper. By scraping it off, problems such as the above-mentioned "rear end climbing up" X are prevented.

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, a collet roller system N550 is provided.

FIG. 33 is a front view of the shifting roller device M 550, and FIG. 34 is a plan view, in which the shifting roller device 550 has a driven shaft 332 held in a shifting roller holder 331 attached to the shaft 340 of the deflection section discharge roller 304. 5 6 Sekoro 333 is attached. Also, the deflection part discharge roller 30
A drive pulley 334 is fixed to the driven shaft 332, and the shifting roller 333 is driven in conjunction with a driven pulley 335 fixed to the driven shaft 332 and a round belt 336. The driving pulley 334 and the driven boob IJ 335 have an inclination of 100 degrees, and the shifting roller 333 can align the copy paper on both sides of the bin fence 450 and the rising portion 508 of the rear end of the bin by shifting the copy paper diagonally. can.

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 paper P conveyed by 07 is discharged into a 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 P
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
Copy paper P that is 20 mm away from the bin 350 and falls onto the shifting roller 333 is scraped onto the bin 350 by the shifting roller 333 . The copy paper P that has fallen into the bin 350 is guided by the inclination of the bin 350 to the rear end rising portion 508 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 340, 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 around 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 time of these swinging rollers and the shifting roller 333 is 7 8 before the next copy sheet is ejected, or when the shifting roller 333 and the bin 35
It is set to end before entering between 0 and 0.

Then, the next copy paper is 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 of pushing the copy paper is too strong, the copy paper P will buckle as shown in FIG. It is designed so that it can transport one sheet of paper, and it will slip after it hits a collision. 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. In addition, 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 stack of copy sheets aligned as described above is taken out in the direction of arrow X in FIG. 14 after various post-processing operations such as stapling operations, which will be described later, are performed. Since there is nothing to support the take-out in this take-out direction, the copy paper take-out operation is easily performed.

Next, the stapler device 700 will be explained.

FIG. 41 is a perspective view of the stapler device 700, FIG. 42 is a plan view of the stapler 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 stapler device 700, the stapler bluff 01 and the paper pulling device 615 are attached to the upper part of a plate-shaped bracket 703 and are each fixed thereto.

are provided, and these rollers 714 and 715 sandwich a bracket 716.

Furthermore, a drive heald 717 is provided upright along the side of the bin 350 and substantially parallel to it. This drive belt 71.7 is inserted between the bracket 703a and the mounting plate 718 and fixed with screws.

The driving belt 717 is passed between belts 719a and 719b which are spaced apart from each other by a predetermined distance in the vertical direction. The power is then transmitted to a pulley 723 via a pulley 721 fixed to the output shaft of a drive motor 720 and a power transmission bell l-722, and a drive gear 724 fixed on the same axis.
The rotational driving force is transmitted to a driving pulley 719a fixed to one end of the support shaft 726 through a gear 725 meshed with the driving gear 724. The drive belt 717 is conveyed by such a driving force transmission mechanism, and thereby the stay bluff 01 and the paper pulling device 715 are conveyed in the vertical direction.

Furthermore, a position sensor 7 is provided on the bracket 711.
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 bins. With such a position detection mechanism, the stay bluff 0
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 1 2 motor 720 stops raising.

FIG. 44 is an explanatory diagram to make the movement of the stay bluff 0100 easier to understand, and the movement of the copy paper P discharged onto the bin 350, the movement of the chuck section 731, and the position of the stay bluff 01 will be explained.

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 abuts against the fence 733 using the swinging device described above. Thereafter, when the copying is finished and stapling is started, the chuck part 731b moves from the position indicated by the dashed dot line to the position indicated by the dashed dot line 7310, closes the chuck part 731, and
Hold c and stop at the position indicated by the solid line. With this operation, the copy paper P moves to the position 730f, and the stay bluff 0
1, a certain number of copy sheets P are stapled on the bin 350. Thereafter, the previous operation is reversed, and the copy P is returned to the position 730d. This is one bottle 35
When the work on 0 is finished, go to the next bin 350 and repeat the operation.

The details of their operation will be explained later.

FIG. 45 is a front view of the paper pulling device 615, FIG.
47 and 48 are front views of the paper pulling device 615 in an operating state, showing a chuck section 620 that grips the stack of copy sheets P on the bin 350 and a reciprocating movement of this chuck section 620 in a substantially horizontal direction. A reciprocating mechanism 640 is provided to allow the reciprocating movement. 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 portion is fixed to a frame 641, and a bearing 629 to which a substrate 621 is fixed is engaged with this shaft 642.
Guided by this shaft 642, the chuck portion 620 reciprocates. The frame body 641 also includes the chuck portion 620.
Tying helmet 64 that advances and retreats toward the copy paper stack P side
3 are provided and 3 4 are provided. The chuck section 620 and the timing belt 643 are fixed by an arm section 621a of the substrate 621. There are pulleys 644 at both ends of the tie belt 643.
, 645 are fixed, and one pulley 644 is attached to a stepping motor 646. The output of the stepping motor 646 rotates the pulley 644 and moves the timing belt 643. As the pufferfish belt 643 moves, the chuck section 620 fixed to the timing belt 643 via the arm section 621a moves back and forth. A position sensor 650 is installed on the frame 641, and a detection plate 630 is installed upright on the substrate 621 as a detection target, and the position sensor 650 detects the home position of the chuck section 620. There is.

In the embodiment having such a configuration, when the stapling mode is started, first the drive belt 7 shown in FIG.
17 to the stay bluff 01 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, so that both swing levers 622, 624 and chucks 623, 625 are in the open position.

Next, the stepping motor 646 rotates by a predetermined amount to move the puffer 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 practical example, the chuck unit 620 grips the aligned stack of copy sheets P with chucks 623 and 625, and gradually accelerates at the start of U and Y, which move back to the stapling position, and gradually decelerates when stopped. This prevents the aligned copy paper from varying due to inertia during acceleration and deceleration. When moving the same five distances within the same time, uniform acceleration motion has the smallest maximum value of inertial force, so in this embodiment, acceleration and deceleration are performed at uniform acceleration.

When the chucks 623 and 625 are moved to a position where they can grip the stack of copy sheets P (FIG. 47), they are 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 stack P. The movement at this time will be explained in more detail. That is, when the solenoid 626 is turned on, the lever 628 is pulled by the spring 627 hooked to the solenoid 626, and the lever 62
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 stack of copy sheets P is held by the upper and lower chucks 623, 66 25. grasp. Chuck top 623
The amount of movement of the lower chuck 625 from the normal position is determined by the lever 62.
・Determined by the length of the rotational fulcrum point 8 and the point of application of force point 2. In the case of this embodiment, if the moving amount of the chuck is expressed as a ratio, it is 46th.
As shown in the figure, in the case of the chuck top 623, the point of action 62
The distance between 2b and the fulcrum 622a is 92 mm, and the point of force 622c
Since the distance between and the rotation fulcrum 623a is 33 mm, it is 92:33 #2.19:L, and the lower chuck 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=Q, 79:1, and the ratio of the amount of movement between the upper chuck 623 and the lower chuck 625 is 2.79:0. .79#3°53:1. In other words, when the upper chuck 623 moves downward by 3 degrees, the lower chuck 625 moves upward by 1 degree. Also, chuck top 62
The chuck force between 3 and the lower chuck 625 is provided by solenoid 6.
It is determined by the force of a spring 627 attached to 26. As the number of copy sheets P7 8 sandwiched between the upper chuck 623 and the lower chuck 625 increases, the spring 627 becomes longer and the chucking force increases, thereby eliminating problems such as displacement due to insufficient chucking force.

In addition, if the chuck 623 or 625 grips only one corner of the copy paper, the inertia when pulling the paper will cause 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 branched as shown in FIG. 50. The copy paper P may be gripped at a plurality of locations to prevent the copy paper P from tilting even if a moment of inertia is applied.

Next, by reversing the stepping motor 646, the chuck unit 620 is moved back to its original position as shown in FIG. It is moved in parallel and drawn toward the stay bluff 10 side.

When the edge portion of the copy paper stack P is transported to a stable position, it is stopped there. Thereafter, staples are driven into the edge portions of the stack of copy sheets P by the stay bluff 10.

When the stable operation is completed, the stepping motor 64
6 rotates normally, the chuck unit 620 moves forward, and after returning the stapled 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. The movement at this time returns to the state shown in FIGS. 46 to 47 due to the force of the spring 631. Thereafter, the chuck portion 620 is retracted to a predetermined position by rotating the stepping motor 646 in the reverse direction again. The stapler 61.0 and paper puller 615 are then transported downward to the next bin 350, where a stabilizing 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. At the opposing edge 90, there is a bin fence 4 for aligning the copy paper stack P.
50 is provided to stand up from the bin 350. The lower end edge portion of this bottle fence 450 is rotatably attached to a support shaft 451 provided along the lower surface side of the bottle 350, so that the bottle fence 450
is tilted to the open position shown in FIG.

Both end portions of the support shaft 451 are rotatably supported by bearing pieces 456 formed downward 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 lower surface 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.

Further, the bin fence 450 is opened according to the vertical movement of the stay bluff 01 via a fence tilting member. This fence tilting member is a fence movable plate 427 attached to the support shaft 451 side.
and the fence release plate 4 installed on the stay bluff 01 side.
It consists of 54.

The fence movable plate 453 is inserted into a fan-shaped hole opened in one piece 450a of the bin fence 450.
53 is occupied, and when the fence movable plate 453 is rotated downward, the part 450 of the bin fence 450
The lower part of the fan-shaped hole a is brought into contact with the bottle fence 450 so that the bin fence 450 is tilted according to the fence movable plate 453. Furthermore, when the fence movable plate 453 is rotated upward, it is rotated away from the bin fence 450 side without contacting it, so the fence movable plate 453 is freely rotated. That will happen.

Further, the rollers 454a of the fence release plate 454 are extended to a position where they come into contact with the fence movable plate 453, and the fence movable plate 454a is extended when the stay bluff 01 moves up and down.
It is designed to rotate the fence movable 4-piece 2 plate 453 by contacting the fence.

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 portion of the copy paper P discharged onto the bin 350 comes into contact with the bin fence 450 to perform paper alignment.

When this sorting operation is completed, the above-mentioned stay bluff 0
1 begins to descend, and the rollers 454a of the fence release plate 454 on the stapler 701 side come into contact with the fence movable plate 453 of the bottle 350. And fence movable board 453
is rotated to the lower position as shown in FIG. As the fence movable plate 453 rotates, the bin fence 4
50 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 fence movable plate 453 are pushed down to a position below the surface position A of the bottle 350, which is indicated by the dotted chain line in FIG. 52. In this state, the stapling operation as described in the above embodiment is executed.

After the stapling operation is completed, the copy paper stack P is placed in the bin 350.
At the same time as the stay bluff 01 is returned to its original position, the stay bluff 01 is moved downward toward the next bin 350. Then, due to the downward movement of the stay bluff 01, the fence release plate 4
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 operation and stapling operation of the bins 350 are performed when the sorted bins 35
This is done for all 0's.

When stapling is performed on all copy paper stacks P,
The stay bluff 01 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 stay bluff 01 returns, the fence release plate 454 on the stay bluff 01 side is moved to the fence movable plate 452.
However, in this case, the fence movable plate 452 is rotated upward in an idling state as shown in FIG.
0 is not rotated at all. When the fence release plate 454 of the stay bluff 01 is removed from the fence movable plate 453 due to the upward movement of the stay bluff 01, the fence movable plate 453 is returned to the original position shown in FIG. 51 by its own weight.

FIG. 54 is a front view showing another embodiment of the paper 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 stay bluff 01 returns, when 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 fence movable 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

When aligning the copy paper, the fence 460
As shown in FIG. 6, the paper is aligned facing the bin 350. When all sorting is completed and stipple is performed, the fence 450 is rotated approximately 90 degrees as shown in Figures 57 and 58.
The copy paper P can be moved away from the bin 350 to the stapling position.

Below, the operation and control of the embodiment of the present invention will be described in flowchart 1.
Explain according to the following.

FIG. 60 is a flowchart of the overall operation of this embodiment. First, the mode signal sent from the copying machine is received in step 1-1). After copying is started, the size signal is received in step i2), and then the sorter is started. Receive a signal (step 1-3). Upon reception of this mode signal, the sorter motor (sorts).

when stuck) or Bruch motor (Bruch).

When interrupting) is turned on.

First, the blue mode (step 1-4) will be explained. After turning on the Bruch motor 117 in FIG. 1 (steps 1.-5), turning on the switching 5OL 107 in FIG.
Step 1-6) When receiving the paper ejection signal (Step 1-7), the paper is carried in from the population guide 102 (Step 1-8).
>The copied paper is discharged to the upper brochure tray 116 (step 1-9). After the copy paper is ejected, a paper ejection signal is sent to the copying machine (Step 1-10) to notify that the copy paper that has been carried in has been completely ejected. From here on, repeat this operation until the copy is completed (Step 1-1)
1). At this time, copy paper jam detection (not shown in the flowchart) is naturally performed. After the copying is completed, the switching SO+-107 and Bruch motor 117 are turned off in step 1''''12), and the process waits until the next copying operation.

Next, sort and stack modes will be explained.

After turning on the sorter motor 313 in FIG.
-13) Determine whether or not the swing is possible based on the size signal, etc.
If swing is possible (step 1-14), the receiver moves the swing shaft 502 in FIG. 13 to the position corresponding to the received size signal (step 115). Next, when copy paper is ejected from the copying machine, the copying machine transmits a destination bin instruction signal 90 and an ejection signal for the copy paper to be ejected (step 1-1).
6). The destination bin 350 is determined by receiving the discharge signal (step 117). Next, copy paper is carried in from the copying machine (step 1-18). After loading, the entrance sensor is turned on, and at the same time as the population sensor is turned on, the deflection solenoid (SQL) determined by the discharge destination bin instruction signal is turned on (step 119).
) and guide the copy paper to the bin 350<. When the copy paper is discharged (step 1-20), a paper discharge signal is sent to the copying machine.Step 1-21) notifies the copying machine that the paper has been surely discharged onto the bin 350. Based on this signal, the copying machine determines the next destination and the destination after the jam has been cleared. The copy paper is ejected and placed on the bin 350, and after an appropriate amount of time (for example, 3
After 00 ms; step 1-22), the size movement motor 515 shown in FIG. 13 is turned on and the swing shaft 502 is moved (step 1-23) to align the paper in the direction perpendicular (horizontal) to the discharge direction. I do. Note that the tie that moves the swing shaft 502 connects the trailing edge of the copy paper to the entry sensor 3.
22 and 324, and the process is performed based on that (step) 24).

After the swinging operation is completed, if the copy paper is curled, has scratches or folds on the surface, or is charged with a large amount of static electricity, it may rarely reach the end of the bin 350 or the bin fence 450.
There is copy paper that does not reach this point. Work is done to forcibly bring it to the edge.

Therefore, at the same time as the swing shaft 502 moves, the shifter 5OL
340 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 it to the edge (for a certain period of time -200 m5; Step 1-26).

This shifting roller 333 is attached to each bin 350, and all of them are lowered at the same time by shifting 5QL 340. After completing this operation, turn off the 5OL 340 <Step 1-
27) Do.

The above operations are performed every time a copy is ejected, and the paper is sorted (step l-28). When the sorting is completed as shown in this 1, the sorter motor 313
is off (step 1-29), and the stapling operation is performed. When the stapling start signal is received (step 1-
30), the stapler device 700 does not operate, step 1-
31) Stapling the stacked 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 paper alignment operation;
Figure 2 (al to +dl are explanatory diagrams showing the operation of the swing shafts, and the swing shaft 502 is located at the position based on the size signal as described above (in this embodiment, the swing shaft 502 is positioned at the position where the copy paper is ejected).
It is stopped in advance at a position 10 mm from the end face on the second side.

This is a position where the ejected copy paper P will not hit the swing shaft and cause jams, paper folds, etc. [Fig. 62 (a)
)]. After 30 Qms after the copy paper is ejected, the paper is aligned by swinging motion.

First, the size movement motor 515 (stepping 2 motor) is moved so that the swing axis 502 approaches the paper by 25 mm, that is, the phase signal is output from the I10 port 803 in the CCW direction by the number of pulses equivalent to 15 mm, and the constant voltage driver 8
11 to move the swing shaft 502 [Step 2-1; FIG. 62(b)]. The speed at this time is 500 pps, and any speed that does not cause defects such as wrinkles, scratches, and folds on the copy paper P is sufficient. Due to this operation, the copy paper P discharged onto the bin 350 is pressed against the bin fence 450 by an excessive feed of 5 mm. This excessive pressing is done to compensate for variations in the length of the copy paper P and for ensuring accurate alignment.
It doesn't have to be 5 mm, but any suitable value is fine.

After pressing the copy paper P, it stops - degrees (59 m5 in this embodiment; step 2-2). This is copy paper P
This function is used to stabilize the speed and to switch the 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 3 4 so as to move away from the paper by 5 mm, that is, by the number of pulses equivalent to 5 mm in the CW force direction [Step 2-3; FIG. 62(C)]. The speed at this time is 300 pps, which is slower than the speed at which the copy paper P returns due to excessive shearing, and may be at a speed that does not disturb the alignment once the copy paper P returns due to its elasticity.

Also, by returning 5 mm and stopping, the swing shaft 502 plays the role of a bin fence on the opposite side when it matches the paper width, and by stopping for another 50 ms (Step 2
-4), the copy sheets P are reliably aligned. Thereafter, the swing shaft 502 returns to the initial position (step 2-5; FIG. 61 (dl)) and stops (step 2-6) in preparation for ejecting the next copy paper. It is sufficient if the speed is at least in time to eject the copy paper.

By the way, after the number of copy sheets stacked in the bin 350 exceeds the number of sheets that can be stabilized (30 sheets in this embodiment), stapling of the ejected copy sheets is prohibited and sorting becomes obstructed. The swinging is stopped and the photographing shaft 502 is retracted to the home position.

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 (steps 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 stapled (step 33), the swinging shaft 305 is retracted to the home position (step 3-4) mainly through the swinging operation and the rolling motion (step 3-4). Step 3-5): From then on, no paper alignment is performed on 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 with reference to the flowcharts in FIG. 64 f81 to FIG. 64+il. After sorting is completed, if copy paper is placed on the bin, the copying machine transmits a stapling start signal, receives this signal, sets the sequence counter to O (step 4-1), and starts operation. . First, the stapler device 700 in the 56-1 position is moved to the first bin to be stabilized (step 4-2). After the stapler device 700 moves to the first bin, the 64th bin
The operation proceeds based on the value of the stapling operation sequence counter described in Figure fal. When the stapler device 700 finishes moving to the first bin, the value of the stable sequence counter is set from 0 to 1 (step 43). When the value of the stapler sequence counter is 1 (step 4-4), the value of the stable sequence counter is set from 0 to 1 (step 4-4), as shown in FIG. (Turn on the chuck morph (stepping motor) 646 as shown in 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 bin 3
This is the amount that can chuck a stack of copy paper over 50mm.

When the chuck part 620 finishes moving forward (step, !-
7), set 2 to the stable sequence counter, step 4-8), and proceed to the next operation.

When the stable sequence counter value is 2, the 64th
As shown in Figure (C), the chuck 5OL 626 is turned on (step 4-9), thereby chucking the stack of copy sheets. The staple sequence counter is then set to 3 (step 4-10), and the operation proceeds to the next step.

When the stable sequence counter value is 3, the 64th
Start the timer as shown in figure fdl (step 4
-11) Hold the state for 0.2 seconds, and after 0.2 seconds have passed (step 112), stop the timer (step 4).
-13), set 4 to the staple sequence counter, step 4-14), and proceed to the next operation.

When the stable sequence counter is 4, the 64th
As shown in figure (e), turn on the chuck motor 646 and step! -15), move the chuck part 620 to the home position. Chuck home sensor 6 detects completion of home movement of chuck unit 62780
50 is turned on, step 4-16), chuck part 620
has finished moving to the home position, and the chuck motor 646
(Step 4-17). Then, set 5 to the staple sequence counter (Step 118).
, proceed to the next operation. At this time, the speed of the chuck motor 646 is uniformly accelerated so that the chucked stack of copy sheets does not shift. In this embodiment, the speed is started from 600 pps and slowed up to 2000 pps.

When the value of the staple sequence counter is 5, the 64th
As shown in Figure (f), check the output of the paper presence/absence sensor 675 in Figure 48 (Step 4-19), and if there is paper, turn on the staple motor (Step 420), and perform the binding operation of the copy paper stack. . 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 the stapling sequence counter is set to 6 (Step 4-23).
, if there is no paper, do not perform the stapling operation and turn off the chuck 5OL626 (Step 4-24), and set the staple 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 to return the stapled copy paper stack to the bin 350 as shown in FIG. 64(g) (step 4-26). 4-27). After feeding the set pulse amount (step 4-28), the chuck motor 646 is stopped (step 4-29), the chuck 5OL 626 is turned off (step 4-30), and the chuck arms 622, 624 of the copy paper stack are released.

After that, start the timer (step 4-31), check the chuck 5OL626 response time of 0.2 seconds (step 4-32), and stop the timer (step 4-33).
), set the staple sequence count to 7 (step 4-34), and proceed to the next operation.

9 0 When the value of the sniper 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 staple 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(i). 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 staple sequence counter is set to O (step 4-42).

The operations of the staple 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 explaining slow-up/slow-down. In the sub-routine called every 1m5EC, after turning on the vertical movement mokutsu 20 (step 5-1), go to slow-up 2-2. If the knob operation is not completed (step 52), the slow-up counter is incremented by one for each subroutine call (step 5-3).

ROM8 whose speed is set to gradually increase based on the value of the slow-up counter (step 5-4.)
Select the speed data from the speed data group within 01.
Sign in to C804 (Step 5-5)
. A phase signal generating section 81 in FIG. 59 generates a frequency based on the speed data set from this CTC 804.
Sent to 3. A phase signal is sent from the phase signal generation unit 813 to the constant current driver 812, and the 1-down 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), stop the slow-up.Step 5-
7) The vertical movement motor 720 then operates at a constant rotation speed.

After a certain period of time, the slowdown operation will start. Step 5-
8) The slowdown counter increments by 1 for each subroutine call (step 5-9). Based on the value of the slowdown counter, the speed data is transferred to the CTC 8 from among the speed data group in the ROM 801, which is set so that the speed gradually decreases (step 5-10).
04 (step 5-14), this CTC8
04, a frequency based on the set speed data is generated and sent to the phase signal generation section 813. A phase signal is sent from the phase signal generation unit 813 to the constant current driver 812, and the 1-down movement motor 720 operates at a rotation speed corresponding to the speed data.

When the slowdown counter reaches a certain set value (step 5-1.2), the slowdown is terminated (step 5-13), and the 1-down movement motor 720 then operates at a constant rotation speed. When the stabilizer 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 (
Step 514).
