Abstract

PURPOSE:To accept the choice of stapling always to contrive to improve user's operability and to reduce useless copies by providing a control means enabling always the choice of whether stapling out of a series of usual copying operations is performed or not. CONSTITUTION:After the lapse of an appropriate period of time until a copying paper is removed and placed on a bin 350 and the copying paper is at a standstill, a size shift motor 515 is turned ON to move an oscillating shaft 502 so that sorting is performed vertically(laterally) to the removing direction. A copying paper bundle is pressed to the bin fence 450 side by the oscillating shaft 502 and positional sorting of one side end faces of the copying paper bundle is performed consequently. When sorting ends, a sorter motor is turned OFF and a staple operation is conducted. When a staple starting signal is received, a stapler device 700 operates to perform stapling to loaded copying papers. A control means enables always the choice of whether stapling out of a series of usual copying operations is performed or not.

FIG. 3 is a front view showing details of the main conveyance section 100, and FIG. 4 (
a) is a side view showing details of the main conveyance section 100, in which 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 claw 103 is connected to a switching solenoid (SQL) 107 via links 104, 105, 106, and when the solenoid 107 is turned off, the copy paper is transferred to the diagonal section 200 provided below the main conveyance section 100. Further, when the solenoid 107 is turned on, the respective parts are fed into the main conveying section 100.

When the solenoid 107 is turned on, the switching pawl 103 is operated, and the copy paper guided into the main conveying section 100 is transferred 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 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 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 pawl 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.

Copy paper conveyed by three vertically arranged conveying rollers 108 and driven rollers 109 is guided by guide plates 101 and 114 and conveyed to a discharge roller 111. The material of the discharge roller 111 is also made of EPDM or chloroprene rubber like the conveyance roller 108.
The driven roller 115 of No. 1 is also the driven roller 109 of the conveying roller 108.
Similarly, 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 bruft 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 by the timing belt 118 via gears 130 and 131 to timing pulleys 119 and 120 fixed to the shafts of the conveyance roller 108 and the discharge roller 111, respectively, and drives the conveyance roller 108 and the discharge roller 111. This is a configuration where there is

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. This means that when the printing tray section 116 is in use mode, the copy paper is conveyed by simply operating the drive motor 117 of the main conveyance section 100 and the solenoid 107, and when the bin 350 is in use mode, 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 shown in FIG. 6, a unit with a different inlet AI is shown. 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 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 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 chloroprene 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 diagonal rollers 202 are disposed with an inclination of ~30''. Similar to the diagonal section receiving rollers 201, these diagonal rollers 202 are also 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. The diagonal section discharge rollers 203 ensure the conveyance to the next conveyance path, and are made of the same material as the diagonal section 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 in the conveying direction of the conveying roller above is 20
1 - speed v8 of the diagonal roller 202 (velocity V of the diagonal section discharge roller 203). However, the speed V of the oblique roller 202! is the component in the downward transport direction, so Vz = v! @xC
O3θ, and in the example, ■2゜wealth■, so V, -
V, cos θ.

Furthermore, the relationship between the conveying force F of each of the above conveying rollers is as follows: Conveying force F of the diagonal portion receiving roller 201 > Conveying force Ft of the diagonal roller 202 # Conveying force F of the diagonal discharge roller 3 . The reason why only the conveying force F of the diagonal receiving roller 201 is increased in this way is that even if the leading edge of the copy paper is fed into the diagonal roller 202, the copy paper is kept diagonally until the trailing edge passes through the diagonal receiving roller 201. The purpose is to prevent this and keep the timing of the tilt constant. Further, the reason why the conveyance force F3 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 conveying 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 FIG. 7.9, 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-toothed timing belt 213.
The driving force is transmitted to the timing pulley 206 fixed to the shaft 1, and the diagonal portion receiving roller 201 obtains the driving force.

Fig. 10 is an enlarged front view of the drive transmission part, and Fig. 7.1 is an enlarged front view of the drive transmission part.
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 the double-tooth timing belt 213 via the idler 208, which is made up of a timing pulley portion 208b and a timing pulley portion 208b.

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 temporary 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 301 and 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.
12 can be individually operated by solenoids. 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.

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 bottles, and FIG. 15 is a side view of the swinging device, showing one part of each bin 350. 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. .

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

As shown in FIG.
500 width C, and extends over a predetermined length toward the bin fence 450.

In this embodiment, the three dimensions are set between 125 and 140 mm. This is the result of experiment, 3 dimensions are 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 achieved. 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 is 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 three dimensions were 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 penetrate vertically through each long portion 511 provided in each bottle 350.

This swing shaft 502 is for aligning the position by coming into contact with the end face of the paper bundle, and the surface of the swing shaft 502 is made of a high-friction rubber member.

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 temporary springs 503a and 503b, which may cause scratches or wrinkles on the copy paper or overload the motor. It has become.

The 18th is an explanatory diagram showing the action of the copy paper and the swing shaft 502, and when the copy paper is curled upward, the swing shaft 502
Even if you try to align it with 02, it will not be possible to align it enough because it will just try to go up side by side as in the state from ■ to ■ in the explanatory diagram of FIG. A high-friction member suppresses the slippage of the copy paper, ensures that the copy paper reaches the bin fence 450, and aligns the copy paper well.

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, a timing bell is inserted into the recesses of the holders 504a and 504b, and extends in the upper and lower regions of the bin 350 in approximately the same direction as the elongated portion 511. 507a and 507b are respectively arranged. Then, the holder 504
8. The convex part of 504b enters and is fixed.

The pulleys 509 and 512 of the boot +J509.510.512 on which the timing belts 507a and 507b are respectively attached are 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 on a boot I7512 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 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), and when ejection is completed, the copy paper is placed at the rear end of the bin. At the same time as it falls onto the rising portion 508, the swing shaft 502 is moved toward the copy paper side, and the copy paper is bitten by a certain amount (5 mm in this example) from the end surface of the copy paper.
It is controlled by pulses so that it has a

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 side 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 surface, and the copy paper is dropped using the slope of the bin 350 as one means of alignment. There is.

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

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 B (part A) shown in FIG. 20], at the bin semi-angular portion 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 39 mm for the bin semi-angular part.

Further, the bin semi-angular portion 402 is provided as a countermeasure against face curl. A stack situation of copy paper exhibiting face curl when the bin semi-angle section 402 is not shown in FIG. 21, and a stack situation of copy paper exhibiting face curl when the bin semi-angle section 402 is shown in FIG. 22. A comparison between the 0 section in FIG. 21 and the d section in FIG. 22 is shown. Copy 0 in Figure 21 indicates that the copy paper stack P is in bin 3.
However, in copy 0 in FIG. 22, the stack of copy sheets P is not far from the top of the bin 350. This is because the shape in FIG. 22 is more face curled than the shape in FIG. 21. In this embodiment, the bin quasi-angle portion 402 has an angle of 15° and a length of 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 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 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 figure, 430a and 430b indicate side plates;
31a and 431b indicate bottle holder stands. Vinfence F
The bottle holder on one side fixes the bottle 350 on a stand 431a, and the bottle holder on the other side only supports the bottle 350 with a slight gap between the stand 431b and the bottle 350. By fixing the bin fence F side, the staple position can be prevented from varying. Further, the bottle holder has a small gap provided on the side of the stand 431b so that thermal expansion of the bottle 350 can be absorbed.

In FIG. 24, reference numeral 511 indicates a long axis 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
Binlip 415 b, 41 to prevent bending.
5c and 415e 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. The lip 415f of the bin 350 is designed to prevent the ejected copy paper from slipping into the long part 511 for the swing shaft.

Figure 28 shows a groove 415f near the long part 511 for the swing shaft.
The ribs 415f protrude above and below the bin 350 to prevent copy sheets 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 1 from the edge of the copy paper size.
It is set near 0mm, especially the long 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. The printed copy paper has rib 41
This is to guide the guide so that it does not get caught on 5f. The rib 415f corresponds to the rising portion 508 of the rear end of the bottle in FIG.
In the vicinity, for example, as shown in FIG. 29, both the upper and lower ribs are low ribs 415f and 415h, and the long portion 511
gradually increasing to. This is done to ensure a large number of sheets to be loaded. Also, the bottle rib 415g in Figure 24
The rib position follows the rib 415f. This rib is provided to improve the falling property of the copy paper.

The 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 strength of the bottle 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.

Figure 31 shows the discharge roller 304 and the rising portion 50B at the rear end of the bin.
It is an explanatory diagram showing a positional relationship with a.

has an angle slightly larger than 90°. The b part is a straight part, and the c part is a curved part. The discharge roller 304 is not located on the same plane as the C section,
It protrudes further in the paper ejection direction than the C portion. The shape of the bottle rear end rising portion 508 shown in FIG. 31 is effective in terms of alignment accuracy in face curling. However, as the number of stacked sheets increases due to face curling, the stack of copy sheets P is stacked higher than the bin riser 420, and the third
"Rising of the rear end" X as shown in FIG. 2 occurs. In this embodiment, by combining the shape of the rising portion 508 at the rear end of the bottle, 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 the face curl, and to prevent the protrusion from occurring. By scraping off the copy paper with the discharge roller 304, problems such as the above-mentioned "back end rolling 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. To compensate for this, a collapsing roller device 550 is provided.

FIG. 33 is a front view of the shifting roller device 550, and FIG. 34 is a plan view of the deflecting roller device 550.
A shifting roller 333 is attached to a driven shaft 332 held by a shifting roller holder 331 attached to a shaft 340 of 04. Further, a driving boo IJ 334 is fixed to the deflection section discharge roller 304, and a driven pulley 335 is fixed to the driven shaft 332.
The shifting roller 333 is driven in conjunction with the round belt 336. The driving pulley 334 and the driven pulley 335 are 100
By moving 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 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 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.
The center of the roller 333 that protrudes by 15 mm is 15 mm away from the rising portion 508 of the rear end of the bottle, and
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 aligned against the bin fence 450. 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 bottle 339 inserted into the hole 338 in FIG. 33 is raised, and the shaft 340 The shifting roller holder 331 rotates counterclockwise around , 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. 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 to pull 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 in this take-out direction that would impede take-out, 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 luff 01 and the paper pulling device 615 are attached to the upper part of a plate-shaped bracket 703 and are fixed thereto. The staple ruff 01 is used to staple each stack of copy paper stacked on each bin (not shown) after sorting, and the paper pulling device W615 grips the stack of copy paper on each bin. do,
It is meant to be transported almost horizontally. The bracket 70

3a is attached, and the 42nd one is attached to the bracket 703a.
．． A bearing 704 shown in FIG. 43 is fitted and fixed with a retaining ring 705 shown in FIG. The bearing 704 is passed through a slide shaft 710 set in holders 708 and 709 attached to a base 706 and an upper plate 707 in FIG. Rollers 714 are attached to shafts 712 and 713 provided on bracket 711.
and 715 are provided, and these rollers 714 and 715
are arranged to sandwich the bracket 716.

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 the mounting plate 718 and fixed with screws.

The drive belt 717 is passed between pulleys 719a and 719b which are vertically spaced apart from each other by a predetermined distance. The pulley 7 is then connected to the pulley 721 fixed to the output shaft of the drive motor 720 and the power transmission belt 722.
23, and a drive pulley 71 fixed to one end of a support shaft 726 via a drive gear 724 fixed coaxially and a gear 725 meshed with this drive gear 724.
Rotational driving force is transmitted to 9a. By such a driving force transmission mechanism, the drive belt 717 is conveyed and driven, and thereby the staple luff 0
1 and the paper pulling device 615 are moved 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 staple luff 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 motor 720 stops raising it.

FIG. 44 is an explanatory diagram for making it easier to understand the movement of the staple luff station 700, and describes the copy paper P discharged onto the bin 350, the movement of the chuck section 731, and the position of the staple luff 01.

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 copying is finished and stapling begins,
The chuck section 620 moves from a position 620b indicated by a dashed dot line to another position 620c indicated by a dashed dot line, closes the chuck section 620 to sandwich the copy paper P, and stops at a position 620a indicated by a solid line. With this operation, the copy paper P moves to the position 730f, and a certain number of copy papers P are stippled on the bin 350 by the staple ruff 01.

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.
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 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 the substrate 621. Pulleys 644 and 645 are fixed to both ends of the timing belt 643, 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 timing belt 643 moves, the chuck part 62 fixed to the timing belt 643 via the arm part 621a
0 moves back and forth. A position sensor 650 is installed on the frame 641, and the substrate 6
A detection plate 630 is erected on 21 as a detection target, and this position sensor 650 detects the home position of the chuck section 620. In addition, the chuck part 6
20 home positions are provided between the position where the stack of copy sheets on the bin 350 is chucked and the position where it is stabilized.

In the embodiment having such a configuration, when the stapling mode is started, first the drive belt 7 shown in FIG.
17 to staple luff 01 and paper pulling device W6
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 both swing levers 622, 624 and chucks 623, 625 are in the 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 section 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 stable position, and gradually decelerates when stopping. 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.

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 and 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 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 upper and lower chucks 623.62
5 grips the copy paper stack 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 length of the rotational fulcrum and the point of force 9. 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#2.79:1, and in the case of the lower chuck 625, the distance between the point of action 624b and the shaft 624a is 26 mm,
Since the distance between the force point 624c and the shaft 624a is 33 mm, the ratio of the amount of movement is 26:33=0.79:1, 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°5, the lower chuck 623 moves downward by 3°5.
25 will move up by 1. Also, the chuck force between the upper chuck 623 and the lower chuck 625 is provided by the solenoid 626.
It is determined by the force of the spring 627 attached to the. As the number of sheets of copy paper P sandwiched between the upper chuck 623 and the lower chuck 625 increases, the spring 627 becomes longer (it is designed to increase the chucking force), 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 stable position to vary, so the chucks 623 and 625 are branched as shown in Fig. 50. In this way, the copy paper P may be gripped at a plurality of locations so that the edge part P does not tilt even if a moment due to 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 staple luff 01 side.

When the edge portion of the copy paper bundle P is transported to a position where it can be stippled, it is stopped there. Thereafter, the stapling is performed on the edge portion of the copy paper stack P by the staple ruff 01.

When the stapling operation is completed, the stepping motor 64
6 rotates in the normal direction, the chuck part 620 moves forward, and after returning the stapled rough 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 rotating the stepping motor 646 in the reverse direction again. Thereafter, the staple luff 01 and the paper pulling device 615 move to the next bin 35.
0, where a stapling operation similar to that described above is repeatedly performed.

FIG. 51 is a front view of the paper alignment mechanism, and FIG. 52 is a front view of the paper alignment mechanism.

FIG. 53 is a front view of the paper aligning mechanism in an operating state, and as shown in FIG. The bin fence 450 that performs alignment is the bin 35
It is provided so that it starts up from 0. The lower edge portion of this bin fence 450 is rotatably attached to a support shaft 451 provided along the lower surface side of the bin 350, so that the bin fence 450 is tilted to the open position shown in FIG. It has become so.

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.

Furthermore, the bin fence 450 is opened according to the vertical movement of the staple luff 01 via a fence tilting member. This fence tilting member includes a fence movable plate 453 attached to the support shaft 451 side.
and the fence release plate 4 provided on the stay luff 01 side.
It has 54 points.

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 of the one piece 450a of the bin fence 450 is brought into contact, whereby the bin fence 450 is rotated according to the fence movable plate 453 (as cited). Furthermore, when the fence movable plate 453 is rotated upward, it is rotated so as to separate from the bin fence 450 side without contacting it, so that the fence movable plate 4
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 staple luff 01 moves up and down, the fence movable plate 454a
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 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 staple rough 0
1 begins to descend, and the roller 454a of the fence release plate 454 on the staple luff 01 side comes into contact with the fence movable plate 453 on the bin 350 side. And fence movable plate 453
is rotated to the lower position as shown in FIG. As the fence movable plate 4530 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 stable 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 that the staple luff 01 is returned to its original position, the staple luff 01 is moved downward toward the next bin 350. Then, due to the downward movement of the stay luff 01, 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 all copy paper bundles P are stabilized,
The staple luff 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 staple luff 01 returns, the fence release plate 454 on the staple luff 01 side is moved to the fence movable plate 453.
However, in this case, as shown in FIG.
0 is not rotated at all. When the fence release plate 454 of the staple luff 01 example is detached from the fence movable plate 453 by the upward movement of the staple luff 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 staple luff 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
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 meshed 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 degrees as shown in Figures 57 and 58.
The copy paper P can be moved away from the bin 350 to the stipple position.

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, the mode signal sent from the copying machine is received in step 1-1). After copying has started, the size signal is received in step 1-2). Receive a sorter start signal (step 1-3). Upon reception of this mode signal, the sorter motor (sorts).

when stuck) or Bruch motor (Bruch).

(at interrupt time) is turned on.

First, the blue mode (step 1-4) will be explained. After turning on the Bruch motor 117 in FIG. 1 (step 1-5), turning on the switch 5OL 107 in FIG.
-7), loading from the entrance guide 102 (step 1-8)
The printed copy paper is discharged to the upper bruft 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 copy is completed, the switching SQL 107 and Bruch motor 117 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), can be oscillated by size signals, etc.

If it is determined that it is not possible, and if it is possible to swing (step 1-14),
The receiver moves the swing shaft 502 in FIG. 13 to the position corresponding to the size signal taken (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 at the same time as the population sensor is turned on, the deflection solenoid (S Q L
) and step 1-19), put the copy paper in the bin 35.
Lead to 0. When copy paper is ejected (step 1-2)
Step 1-21): Send a paper ejection signal to the copying machine.
, informs the copying machine that the paper has been securely 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. After the copy paper is ejected and placed on the bin 350, and after an appropriate amount of time has passed until the movement of the copy paper has calmed down (for example, after 300 m5; step 1
-22), by turning on the size movement motor 515 in FIG. 13 and moving the swing shaft 502 (step 1-23).
), aligns the paper in the direction perpendicular (horizontal) to the ejection direction.

Note that the timing for moving the swing shaft 502 is based on the detection of the trailing edge of the copy paper by the paper discharge sensors 322 and 324 (step 1-24).

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
342 is turned on (Step 1-25), the rotating roller 333 contacts the top surface of the paper, suppresses the curl, and forcibly moves it to the edge (fixed time = 200 ms; 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 342. After completing this operation, turn off SQL SQL 342 (step 1
-27) Do.

The above operations are performed every time a copy is ejected, and the paper is sorted (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. When the stapling start signal is received (step 1-30), the stapler device 700 is activated to staple the stacked copy sheets (step 1-31). When the stapling operation is completed (step 1-32), the stapler device 7
00 and the swing shaft 502 move to the home position (step 1-33).

FIG. 61 is a flowchart explaining the paper alignment operation;
2 (al to d) are explanatory diagrams showing the operation of the swing shaft, in which the swing shaft 502 is positioned at a position based on the size signal (in this embodiment, the swing shaft 502 is moved to the position where the copy paper is ejected). axis 50
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 300 ms after the copy paper is ejected, the paper is aligned by swinging motion.

First, the size movement motor 515 (stepping motor) is moved so that the swing axis 502 approaches the paper by 25 mm, that is, the phase signal is applied in the CCW direction by the number of pulses equivalent to 15 mm.
10 from the boat 803 and driven by the constant voltage driver 811 to move the swing shaft 502 [Step 2-1; FIG. 62(b)]. The speed at this time is 5oo
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 to prevent variations in the length of the copy paper P and to achieve reliable alignment, and the
It doesn't have to be an appropriate value.

After pressing the copy paper P, it is stopped by - degrees (50 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 5 mm away from the paper, 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 3 oopps, 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 stiffness.

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 in preparation for ejecting the next copy paper [step 2-5; FIG. 61(dl)] and stops (step 2-6). The speed at this time is sufficient as long as it is faster than the speed required to eject the next copy paper.

By the way, after the number of copy sheets stacked in the bin 350 exceeds the number of sheets that can be stapled (30 sheets in this embodiment), stapling of the ejected copy sheets is prohibited and sorting becomes obstructed. The swinging is stopped and the swinging 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 (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 stapled (step 3-3), the swinging operation and the rolling motion are stopped, and the swinging shaft 502 is retracted to the home position (step 3-4). (step 3-5), and no paper alignment is performed for the ejected copy sheets thereafter. At the same time, stapling is also prohibited for the previously ejected copy paper (step 3-6).

The stable operation will be explained according to the flowcharts shown in FIGS. 64(a) to 64(1). 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 at the home position is moved to the first bin to be stapled (
Step 4-2), after the stapler device 700 moves to the first bin, the operation proceeds based on the value of the stable operation sequence counter written in FIG. 64 (dl). When the movement is completed, the value of the staple sequence counter is set from 0 to 1 (step 4-3).

When the value of the staple sequence counter is 1 (step 4-4), the chuck motor (stepping motor) 646 is turned on as shown in FIG. 64(b).
5) Advance the chuck section 620 in FIG. 45. Since the moving amount is a stepping motor, it is determined by the number of pulses corresponding to the moving amount (step 4-6), and the moving amount at this time is from the home position of the chuck unit 620 (the position where the chuck home sensor 650 is on) to bottle 35
This is the amount by which a stack of copy paper above 0 can be chucked. When the chuck part 620 finishes moving forward (step 4-7)
, set the staple sequence counter to 2 (step 4-8), and proceed to the next operation.

When the value of the staple sequence counter 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 value of the staple sequence counter is 3, the 64th
Start the timer (step 4) as shown in the figure (dl).
-11) Hold the state for 0.2 seconds, and after 0.2 seconds have passed (step 4-12), stop the timer (step 4
-13), set 4 to the staple sequence counter, step 4-14), and proceed to the next operation.

When the value of the stable sequence counter is 4, as shown in FIG. 64(Q), the chuck motor 646 is turned on (step 4-15), and the chuck section 620 is moved to the home position. The chuck home sensor 650, which detects the end 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 bundle of copy sheets does not shift.

In this example, it starts from 600pps and goes to 2000pps.
I'm slowing it up to s.

When the value of the stable 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), turn on the stapling motor when there is paper (Step 4-20), and start the stapling operation of the copy paper stack. conduct. The end of the binding operation is detected by the staple home sensor 650 (Step 4-21), the stabilization operation is ended (Step 4-22), and the stable sequence counter is set to 6 (Step 4-23).
), proceed to the next operation. When the output of the paper presence/absence sensor 675 is on the copy side, turn off the chuck 5OL 626 that performs the stable binding operation (step 4-24), and set the stable sequence counter to 8 (step 4-2).
5), 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 (step 4-26) as shown in FIG. 27) After feeding the set pulse amount (step 4-28), stop the chuck motor 646 (step 4-29), turn off the chuck 5OL 626 (step 4-30), and then turn the chuck arms 622 and 624 of the copy paper stack. Open.

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).
), the staple sequence counter is set to 7 (step 4-34), and the process moves to the next operation.

When the value of the staple 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), after the backward movement, the chuck motor 646 is stopped (step 4-37), and then 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 (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 staple sequence counter is set to 0 (step 4-42).

The operations of the stable sequence counters O 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 stable 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 which the slow-up operation ends after the vertical movement motor 720 is turned on (step 5-1) in a sub-routine that is called every l m s. If not (step 5-2), the slow-up counter increments by 1 for each subroutine call (step 5-2).
3) R○ whose speed is set to gradually increase based on the value of the slow-up counter (step 5-4)
Speed data is set in the CTC 804 from among the speed data group in M801 (step 5-5). This 0C
A frequency based on the speed data set from the TC 804 is generated and sent to the phase signal generation section 813 in FIG. 59. A phase signal is sent from the phase signal generation unit 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 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 one for each subroutine call (step 5-9). The ROM 801 is set so that the speed gradually decreases based on the value of the slowdown counter (step 5-10).
CTC the speed data from the internal speed data group.
804 (step 5-11). This 0CTC
From 804, 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 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), stop the slowdown.Step 5
-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 (step 5-14).
