Next, the configuration of each mechanical unit will be explained with reference to FIGS. 5a to 11.

First, the configuration of the vertical folding mechanism unit 100 will be explained with reference to FIG. 5a.

The vertical folding mechanism unit 100 includes a paper entry roller 104 and a paper entry gate claw 112.3 that determines the feeding direction of the 1082 paper.
vertical folding rollers 116, 118° 120, vertical folding conveyance rollers 162, 166, and end folding folding plates 197. Equipped with registers 154, 156, etc. for setting vertical folding position,
The required rollers are coupled to a drive power system (not shown) of unit 100.

The paper entry gate claw 112 is fixed to the rotating shaft 110,
This rotating shaft 110 is rotationally driven by a solenoid 114. When vertical folding is not instructed, solenoid 114
In this case, the paper entry gate 112 is placed in the solid line position shown in the figure without being energized. In this state, the paper sent directly below the paper sensor 174 is received by the rollers 104 and 108, but the claw 1
Unit 2 hits the downward surface of Unit 12 and is bent downward.
Go straight to 00. When vertical folding is instructed, when the sensor 174 detects paper, the solenoid 114 is energized and the tip of the claw 112 descends toward the lower roller shaft 106 (the state shown by the two-dot chain line in FIG. 4).

In this state, the paper sent directly below the sensor 174 is
The paper is received by rollers 104 and 108, rides on the upper surface of claw 112, and is sent toward vertical folding rollers 116 and 118°120.

Vertical folding rollers 120 and 118 are in contact, but roller 116 does not contact 120 in any state.

The vertical folding roller 116 is supported by a shaft 122 and is rotatable about the shaft. A plunger of a solenoid 124 is connected to the arm to which the roller 116 is pivoted, and when the solenoid 124 is energized, the roller 116 is
is separated from roller 118, and paper that has passed through the upper surface of pawl 112 can enter between rollers 118 and 116. When solenoid 124 is de-energized, roller 116 is
It is in pressure contact with 18.

The fixed register 178 is for positioning the short side of A2 when vertically folding, and the fixed register 154 is for positioning the short side of A2 when vertically folding A2/quarter-folding.
The movable register 126 for long side positioning is B3 during vertical folding.
The positioning of the short side and the movable register 156 are B3
- For positioning the long side of 8a when vertically folding into four.

Plungers of solenoids 130 and 160 are coupled to movable registers 126 and 156, respectively. When solenoid 130 is de-energized, register 12
6 is retracted from the vertical origami paper transport path. solenoid 130
When the register 126 is energized, the register 126 advances into the longitudinal folding paper transport path and stops the incoming paper therein. Solenoid 160
When the register 156 is not energized, the register 156 is retracted from the vertical folding paper transport path. When the solenoid 160 is energized, the register 156 advances into the longitudinal fold transport path and stops the incoming paper there.

Rollers 166 and 162 are connected to rollers 104 and 10 when solenoid 124 is energized and roller 116 is pulled up.
8 to feed the paper introduced through the upper surface of the pawl 112 to the register 178 or 126. After the leading edge of the paper is placed against register 178 or 126, solenoid 124 is de-energized and the paper is sandwiched between vertical folding rollers 116 and 118. In this state, the paper is sent toward the register 154 or 156 by these rollers 116 and 118, and when one side of the paper hits the register 154 or 156, the paper bends when it passes between the rollers 116 and 118, and this bending The paper becomes larger and is caught between the rollers 118 and 120, folded in half vertically, and sent to the unit 200 through the delivery port (a slit-shaped opening parallel to the axis of the vertical folding rollers) directly below the rollers 118 and 120. A steel ball 169 is placed on the roller 166, and a steel ball solenoid 164 is placed opposite the roller 162 so that the rotation of the rollers 166 and 162 does not provide resistance to the movement of the paper during such vertical rotation. ing.

The steel ball 169 is supported by a ball support (not shown) so as to be rotatable in multiple directions, and is always in contact with the roller 166, and when paper arrives, it presses the paper against the roller 166 with its own weight,
Rotates as the paper moves. Therefore, when the paper is moving directly under the vertical folding roller 116 in the axial direction of the roller, the rotation of the roller 116 drives the paper in that direction. When the paper moves in a direction perpendicular to the axis of the vertical folding roller 116 (vertical folding in two), the steel balls 169 rotate as the paper moves, so they do not interfere with the paper movement.

The steel ball solenoid 164 has a structure in which an electric coil is wound around a magnetic core, and when the electric coil is energized, the steel ball 165 is attracted to the core and separated from the roller 162. Steel ball 1
65 has roughly the same effect on the paper as the steel ball 169, but when the paper is driven in a direction perpendicular to the axis of the vertical folding roller 116 (folding in two vertically), the steel ball 65 is activated by energizing the electric coil. 16
5 from the roller 162 (paper) and
reduce frictional resistance.

The folded plate 197 is fixed to a carriage 198, and this carriage 198 is moved in the direction of the arrow (
The roller 116 is guided so as to be able to reciprocate in the axial direction of the roller 116. A link arm 196 is pivotally connected to the carriage 198, and another link arm pivotally connected to this link arm is fixed to the output shaft of the half-rotation clutch 136. A gear fixed to the input shaft of the half-rotation clutch 136 is engaged with a drive power system (not shown) of the unit 100. When the half-rotation clutch 136 is energized, it rotates the link arm 196 half a turn clockwise to drive the carriage 199 (that is, the folded plate 197) to the right, and when the energization is cut off, the half-rotation clutch 136 rotates the link arm 196 in the opposite direction. The carriage 199 (that is, the folded plate 197) is driven to the left by making a half turn clockwise.

FIG. 5a shows the folded plate 197 in the standby position.

To the right of the folded plate 197 is a push plate 138. This push plate 13
8 is fixed to the U-shaped arm 140, and arm 1
40 is pivotally mounted to a carriage 142. The carriage 142 has a guide bar 193 parallel to the guide bar 199.
It is guided so that it can freely move back and forth. An arm 146 is fixed to the carriage 142, and the tip 1 of the arm 146 is fixed to the carriage 142.
95 projects into the path of the carriage 198. A roller 152 is in contact with the U-shaped arm 140,
This roller 152 is pivotally attached to one end of the rotating arm 148. A solenoid 15 is attached to the other end of the rotating arm 148.
0 plunger 150 is coupled. In the state shown in FIG. 5a (standby state), the U-shaped arm 140 is held loosely by the roller 152. The push plate 138, in which the U-shaped arm 140 is fixed to the U-shaped arm 140 in a dogleg shape, is lifted upward by a spring 145 (leftward pull) and a spring 144 (upward pull). . In this state, the paper fed between the rollers 116-118 passes through the space between the folding plate 197 and the pushing plate 138. When the solenoid 150 is energized, the arm 148 rotates counterclockwise, and the roller 152 strongly presses the arm 140. As a result, the U-shaped arm 140 rotates counterclockwise, and the entire pressing plate 138 becomes lower than the upper surface of the folding plate 197, pressing the paper downward. In this state, half-rotation clutch 1
36, the folding plate 197 moves to the right and the push plate 1
Fold the paper as you cross over 38. Folded plate 197
moves to the right to a certain extent, the carriage 198 pushes the tip 195 of the arm 146 to the right, and as a result, the push plate 13
8 also moves to the right. The U-shaped arm 140 is the roller 1
52 to the right, the U-shaped arm 140 is prevented from returning to the left by a roller 152. When the half-rotation clutch 136 is de-energized in this state, the folded plate 197 returns to the standby position shown in FIG. 5a. When the solenoid 150 is de-energized, the U-shaped arm 140 pushes up the roller 152 due to the force of the spring 144, thereby pushing the push plate 1
38 moves upward and moves to the left by the force of the spring 145, resulting in the standby state shown in FIG. 5a.

Fig. 5b shows an enlarged plane of the folded plate 197, and Fig. 5c shows its v.
The edge of the folded plate 197 on the side of the push plate 138, whose cross section is shown along the c-vc line and the VD-VD line is shown in FIG. The chain line) is folded so that it is easy to hold in your mouth. Further, the tip of the folded plate 197 has an oval shape to prevent the paper from escaping. When A2 paper is positioned using the register 178 and when B3 paper is positioned using the register 126, the first corner of the paper PR (double-dashed line) is the fifth corner.
As shown in Figure b, the paper PR is triangular and rests on the folded plate 197, and the paper PR is between the folded plate 197 and the push plate 138. This state is shown in FIG. 5e.

In this state, when the solenoid 150 is energized.

The paper is pressed against a lower paper guide plate (not shown) by a press plate 138. When the half-turn clutch 136 is energized, the folding plate 197 moves to the right as shown in FIG. 5f, folding the corner of the paper over the push plate and the paper above it. As the folding plate 197 advances further, the push plate 138 also moves to the right, and the push plate 1
38 comes out from the folded part of the paper to the right. Half rotation clutch 1
36 is cut off, the folding plate 197 moves to the left as shown in Fig. 5g, and finally reaches the standby position I! Return to (Figure 5e). When the solenoid 150 is de-energized, the push plate 1
38 returns from the position shown in FIG. 5g to the standby position (FIG. 5e) by the force of the spring 146. At this time, spring 1
44 causes the push plate 138 to rise upward and not come into contact with the folded corner piece of the paper PR.

Although not shown, a fixed register 154 used for vertically folding in half for A2/4 folding and a movable register 156 used for vertically folding in 2's for 83/4 folding are parallel to The movable register (154J) and B3

The rollers 162, 166 and 118 and the half-turn clutch 136 human power system are all selectively connected to the main power system through one clutch. The main power system starts moving in response to a start signal and stops when a predetermined condition is met. For example, it is stopped when an end signal arrives, when a predetermined time has elapsed since the sensor 174 stopped detecting paper, or when a paper jam occurs. The clutch has A2/4-fold mode, A2/JI
It is energized when the S-fold mode, B3/4-fold mode, and B3/JIS fold mode are set.

A threaded rod 448 is screwed into the support plate 436, and the threaded rod 448 is rotationally driven by a pulse motor 450. When the punch bar 442 is at the punching position of A4 (the distance between the middle of the two punch bars 442 and the fixed register 460 is half the long side of A4), the striker of the support plate 43G hits the position. Limit switch 484 is fixed. When switch 484 is closed (FIG. 8 state), the punching device is in the A4 punching position. When punching the B version, the B5 punch position based on the fixed register 460 (the distance between the middle of the two punch bars 442 and the fixed register 460 is
The pulse motor 450 is energized to rotate normally by an amount equivalent to the distance difference between the 1/2 value of the long side of B5) and the A4 punch position, and is stopped there. When changing from a B size punch to an A size punch, the pulse motor 450 is reversely energized until the switch 484 is closed.

The register 426 is for punch positioning of A4 paper.
The register 422 is for punch positioning of B5 paper. Plungers of solenoids 428 and 424 are connected to registers 426 and 422, respectively, and when the solenoids are energized, they advance into the paper transport path and stop incoming paper.

Immediately below the punching device, steel ball solenoids 418 and 482 are placed above roller 416 and another roller to accurately position the paper during punching. The other main rollers are loaded with steel balls.

478 and 480 are paper sensors.

Above the entry side rollers 404, 408, there is a unit 30.
A cutter 452 for cutting jammed paper spanning 0 and 400 is arranged. The support structure and drive system of this cutter 452 are the same as those of the cutter 223 shown in FIG. 6a, so a description thereof will be omitted. When switch 476 (FIG. 1) is set to - moment, cutter 452 moves back and forth once to cut the jammed paper. Paper is sent out from the punch mechanism unit 400 in the direction shown by an arrow 403 and sent to the stamp unit 500.

On each of the five sides of the pentagonal first printing 1i4540, a rubber plate with stamp characters (reversed characters) indicating the type of drawing such as official drawing, provisional drawing, approved drawing, etc. is pasted. The first design is printed on each of the five sides of the pentagonal second printing cylinder 541.

A rubber plate with stamp characters (reversed characters) indicating the issuer of the drawings such as 2nd design, equipment, etc. is attached.

Between the first printing cylinder 540 and the second printing cylinder 541, a date stamper 556 having the same structure as a commercially available date stamper is disposed, and this has four ronds 558 and a second printing tool.
It is fixed to a support plate 526. The date is stamper 556
is the printing side (the side facing the ink roller 560 at the tip)
There are reverse numerals for stamps, but the same numerals that appear on the printing side appear upright (normally visible) on the rotating wheel for changing the date.

The base frame 502 is supported by guide bars 562 and 564 fixed to a case frame (not shown) of the stamp mechanism unit 500 so as to be movable in a direction perpendicular to the paper feeding directions 403 and 501. The case frame has a free rotating ring 514.

A positioning arm 570 fixed to a case frame (not shown) is located directly below the stopper 566. This arm 570 is formed with a large number of rectangular notches into which the lower end of the stopper 566 is received. By pulling up the stopper 566 and pushing the base frame to the back side, the stamp position relative to the paper moves to the back side in a direction perpendicular to the paper feeding direction. By pulling it toward your hand, the stamp position moves toward you. In this way, the stamp position in the direction perpendicular to the paper feeding direction can be manually adjusted. The stamp position in the feeding direction of one sheet of paper is adjusted by adjusting the drive start timing of the pulse motor 520 (support plates 512, 526) based on the arrival of the leading edge of the sheet of paper. As described later,
This timing is set by an electrical signal and is done automatically.

The ink roller 560 is as shown in FIG. 9b.

It is pivotally attached to a support frame 560. Sliders 586 (two sliders) are mounted on the support frame 584 so as to be movable in the direction of arrow 593 and the opposite direction. A compression coil spring 589 is inserted between the two sliders 586.
It gives force to both sliders to pull them apart. The support frame 560 has a notch 590 for pin engagement, and the slider 586 has a pin guide hole 587 and a pin guide groove 58 continuous thereto.

The second support plates 512 and 526 are rotated counterclockwise, and just before the printed surface faces the roller 574, the solenoid 578 is energized to pull up the roller 572. When one side of the printed surface passes the roller 572, the solenoid 578 is activated. One printing operation is performed by cutting off the power supply and lowering the roller 572. Note that while the printed surface moves from the standby position (home position) shown in FIG. 9a to the roller 572, the printed surface comes into contact with the surface of the ink roller 547,
The surface of roller 547 is slightly compressed. As a result, the ink on the roller 547 is transferred to the printing surface. An example of the stamp image is shown in FIG. 15c.

An upper cover 594 is attached to the base frame 502. The state in which the upper cover 594 is attached is shown in FIG. 9c. In FIG. 9c, the manual rotary wheel 522 is rotated to move the date change ring portion of the stamper 556 directly below the opening 594 of the cover 594. overturn the condition. The date can be changed in this state. Note that the date is manually adjusted in this way, but the date stamper 556 on the base frame 502 is placed in a position where it can face the date changing axis, and the date changing roller is moved using a solenoid or the like. Provided so that it can be driven forward and backward,
When changing the date, drive the motor 520, set the date stamper in a position facing the changing roller, push out the roller, press the date against the changing shaft, and drive the roller to rotate. good. In this way, the date can be changed automatically. Further, a driving mechanism may be coupled to the base frame 502 to automatically drive the base frame 502 in a direction perpendicular to the feeding direction of one sheet.

Details of the operation of the stamp unit 500 described above will be described later with reference to the flowcharts shown in FIGS. 15a and 15b.

Open in the direction of arrow 605 to take out the paper. If the jammed paper is spread over units 600 and 700, turn the grip 634 to pull the paper into unit 600, then pull out unit 600 from the main body of sheet processing machine 900, and remove the inner cover. Open it in the direction of arrow 605 and take out the paper.

Next, the configuration of the paper ejection mechanism unit 700 will be explained with reference to FIG. 11.

The paper ejection mechanism unit 700 includes paper receiving rollers 706.7.
08. Gate claw 71'2 that determines the paper feeding direction. A conveyance path to the sorter 1000, feed rollers 720 and 722 placed on this conveyance path, and a paper sensor 736. ) - consists of a conveyance path to the ray ET, feed-out rollers 726 and 728 placed on this conveyance path, and a paper sensor 734, and a slit plate 730 of a rotary encoder is fixed to the roller shaft 704.

When the paper is instructed to be ejected to the tray ET, the solenoid 716 remains de-energized, and the paper is transferred to the gate claw 712.
The lower curved surface of the paper is directed towards rollers 726, 728, by which it is fed in the direction of arrow 701 to the tray ET.

When a paper is instructed to be discharged to the sorter 1000, the solenoid 716 is energized and the gate pawl 712 rotates clockwise to guide the paper toward rollers 720 and 722.One paper is guided by these rollers in the direction of arrow 703. was sent to
This leads to sorter 1000.

As explained earlier, the vertical folding mechanism units 100 and 90@
The paper is fed to the roller 254 of the turn mechanism unit 200 at a speed similar to or slightly faster than the paper feed speed of the copying machine 800, but the feed roller 211 of the 90° turn unit 200 and the next blade folding mechanism unit 300 The rollers 304 and 308 feed the paper at a faster speed,
The rollers after roller 310 of the blade folding mechanism unit 300 feed the paper at an even faster speed. In this way, the sheet processing machine 9
The reason why the paper feeding speed is made faster as it goes downstream in the sheet processing machine 900 is to prevent a paper power outage in the sheet processing machine 900, so that if a paper jam occurs in the sheet processing machine 900, the paper feeding from the copying machine is immediately stopped. This is to reduce the number of sheets to be fed and to widen the interval between sheets fed to the sorter 1000.

13a to 13d, the operation board control unit l
The control operation of the operation board control unit 10, that is, the control operation of the microprocessor 14, will be described with reference to these drawings showing the control operation of the microprocessor 14 of O.

First, reference is made to FIG. 13a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input/output ports, registers for temporary data storage, status registers (flags), counters (program counters), timers (program timers), etc. (Step 1). In the following, the word "step" will be omitted in parentheses, and only the step symbol will be displayed.

After completing the initialization, the CPU 14 reads the status. First, it is checked whether there is a read flag (2
). At this point, initialization has just been completed and there is no read flag, so proceed to step 3 and set standard data in the operation board register. Standard data is: Paper size: A4 Digit selection: Unfolded portrait/horizontal orientation: Horizontal Stamp position 20m - Publisher: 1st design (1st publisher's stamp) Drawing type: Temporary drawing (1st drawing type) Punch Selection: No punch paper output selection. When this data set is completed, the indicator light corresponding to the data is lit accordingly. In this state, on the operation board 12, standby (this is set at initialization),
A4. Indicator lights each indicating ``no fold'', ``horizontal'', 0■, no punch, 1st design, tray, and temporary drawing are lit.

FIG. 12b shows the writing position of data temporarily written to the 3-byte memory area (an area of the internal RAM of the CPU 14) allocated to the operation board register OBR.

When the standard data is written to the operation board register OBR, a read flag is set (4). Next, referring to the state of the port that receives the input signal from the copying machine 800, the copying machine 800
Determine whether or not a signal is transmitted from 0 (5). If there is transmission, receive it, read the signal and data, and determine whether the signal is a start signal (6). If it is not a start signal, it is an end signal. 7), and if it is not an end signal, it is data, so of the input data, the data whose memory bit is assigned to the operation board register ○BR is written to the operation board register to update the OBR. When such update writing is performed, the operation board register O
1 is written in the bit indicated as the copying machine input bit in BR. This 1 indicates that the copying machine &00 has instructed the sheet processing machine 900 on how to process the sheet. Although not shown, the CPU 14
Data received from the copying machine and indicating what has been written to the operation board register OBR (indicating what the written data is) is held in the memory. If data is received from the copying machine 800 and writing to the operation board register OBR is completed and the process proceeds to step 9, or if there is no input from the copying machine 800 and the process proceeds from step 5 to step 9, the operation board is Read the key-in of 12, and if the key-in is from the key switches 12a to 12e (
10), refer to the copier input bit and if it is not 1 (
data has not been received from the copier yet) and (11),
The contents of the operation register are updated according to the key-in, and the indicator light on the operation board is turned on.

Update Off to match this update. For example, when the switch 12a is closed, the size designation bit of the operation board register OBR is updated to data indicating the next 83 of A4 at the moment it is closed, and the indicator light of A4 is turned off and the indicator light of B3 is turned on. do. When the key switch 12a is closed once when the size designation bit of the operation board register OBR is 85, the size designation bit is updated to data indicating A2, the B5 indicator light is turned off, and the A2 indicator light is turned on. do. In this way, each time the size indication key switch 12a is closed, the lighting of the indicator light moves from the upper side to the lower side in FIG. The data is updated to indicate the size indicated by the light. However, this operation is
This is performed only when size data has not been received from 00; if size data has already been received, step 1
The process proceeds to 1-12-■, and data and display updates are not performed in response to the key-in. The CPU 14 operates in a similar manner in response to key-in using the key switches 12c to 12h.

The reason why the input data from the copying machine 800 is given priority over the settings made by the operation board 12 is that the input data from the copying machine 800 is prioritized.
This is because data starting from 00 is more reliable. When no data is received from the copying machine (for example, when the copying machine is not connected), or when only part of the required data is received, the missing data is updated and set in accordance with the key input from the operation board 12. When no data is given from the copying machine and there is no key-in on the operation board 12, the setting data becomes the above-mentioned standard data. Although it is different from the step development of the illustrated flowchart, a start signal for the mechanism of the sheet processing machine to start operation is also received from the copying machine 800, and is also keyed in with the start key switch 12+ of the operation board 12. However, when even part of the data is being received from the copier 800 (copier input bit of OBR = 1), switch 1 is
The key-in of the start signal by closing 2i is step 3.
I try not to add Uke at 8. In this way, even when starting the processing mechanism, priority is given to the start signal from the copying machine.

The operation board 12 and its key-in read/data set are used when no copying machine is connected, and.

This is meaningful when the sheet processing machine 900 is connected to a copying machine that does not transmit all the required data, and when no external device (host) is connected to the sheet processing machine 900, or when the host's insufficient functions are compensated for by key-in. cormorant.

Now, if you set the data in step 8 (set the data received from the copying machine), or if you set the data in step 13 (set the key-in data), or the copying machine does not send data (5)L Maybe there is no key-in (9).

Proceeding to step 14 in FIG. 13b, the signal level of the signal receiving port from the unit 20 is referred to see whether it is ready (paper can be accepted) or not (standby: paper cannot be accepted).

If the vertical fold &90' turn control unit 20 is ready in step 14 of FIG. Check whether the is ready or not.

If the punch control unit 40 is ready, step 2
0, it is checked whether the unit 50 is ready. If the standby control unit 50 is ready, it is checked in step 22 whether the unit 60 is ready. When the vertical conveyance & paper ejection control unit 60 is ready, all units are ready and can execute sheet processing, so set the ready standby bit of the operation board register ○BR to 1 indicating that processing is possible L (24) , Compare the data in the operation board register ○BR and the data in the previous operation board register POBR (25). Note that the previous operation board register ○BR was cleared in the initialization in step 1, so proceed to step 25 for the first time. If so, the contents of the two do not match, which means that each unit 20 to 60 from step 27 below
This means that the processing mode data transfer is not executed.

Therefore, first in step 26, the operation board register OBR is
The data is updated and stored in the pre-operation board register POBR, and the process proceeds to setting the A version processing mode to the unit 20 (27) in FIG. 13c.

In setting the A version processing mode to the unit 20 (27) in FIG. 13c, first, the size is determined from the data of the size designation bit of the operation board register OBR (271).
.

If the size is A2, then refer to the digit selection bits of OBR (272 to 276); if the size is unfolded, unit 2
Send data indicating A2/vertical/passing mode to 0 (2
73), when folding into four, data indicating A2/vertical folding mode is transmitted to the unit 20 (275). When folding in half, data indicating A2, vertical, and passing mode is sent to the unit 20 (277) - and when it is JIS folding,
Data indicating A2/end face folding/JIS vertical folding mode is transmitted to the unit 20 (278).

If the size is not A2, the process advances to step 279 to see if it is A3.

If the size is A3, it refers to the length/width designation bit of the OBR, and if it indicates the height (280), it transmits A3/vertical/pass mode to the unit 20 (281).

When it indicates the side.

Refer to the digit selection bit of OBR (282), and if it is correct, transmit A3/horizontal/passing mode to the unit 20 (283). Unit 20 if there is some kind of incident.
, send A3 90° turn mode.

When the size is A4 (285), refer to the height/width specification bit (286), and if it indicates the width (286),
86), send the A4/horizontal/passing mode to the unit 20 (287); if it does not indicate horizontal, the unit 288
The A4 90° turn mode is then transmitted (288).

When the size is the B version, in step 28, a mode corresponding to the size etc. is transmitted to the unit 20 in the same manner as in step 27 described above. Step 27 A2 to B3, A3 to B
4, and if A4 is read as B5, it becomes the content of step 28.

With the above, when unit 20 is ready, unit 10
A control operation mode instruction is given to the unit 20 from the control unit 20, and is set in the microprocessor of the unit 20.

The CPU 14 of the unit 10 then proceeds to setting the blade folding mode (29) in FIG. 13d. In this step 29,
First, the digit selection bits of the operation board register OBR are referred to (291, 292, 294). Then, when there is no fold, size data is attached and the pass is sent to the unit 30 (295), and in the case of four-fold, two-fold, and JIS fold, the data and digit of the size designation bit of the operation board register ○BR are sent. The selected bit data is transmitted to the unit 30 (293, 296). With the above, the unit is 1° to 30
A control operation mode instruction is given to the unit 30 and set in the microprocessor of the unit 30.

After completing the setting of the blade folding mode (29), the unit 101
7) The CPU 14 sets the punch mode (3o).

In this case, the operating board register OBR.

Referring to the size specification bit data, digit selection bit data, and punch selection bit data (301 to 30
6, 308, 309), when the final size is A4 and punched, A4/punch mode should be sent to unit 40. 307), when the final size is 85 and punched, B5/punch mode should be sent to unit 40. 310) , otherwise send the non-punch mode to the unit 40.

After completing the punch mode setting (30), the CPU 14 of the unit 10 sets the stamp mode (3).

In this case, the stamp selection bit of the operation board register OBH is referenced (312), and if it is 1 indicating a stamp, the stamp selection bit, stamp position bit, issuer selection bit and Send drawing type selection bit data (313)
. A stamp selection bit of 0 sends a non-stamp signal to unit 50.

After completing the stamp mode setting (31), unit 10
The CPU 14 sets the paper discharge mode (32).

In this case, refer to the paper ejection selection bit in the operation board register OBR (321); if it is 1, it instructs the unit 60 to eject the paper to the sorter (323), and if it is 0, it instructs the unit 60 to eject the paper to the tray (323). 322).

After setting the paper ejection mode (32), units 20 to
This means that the control operation mode is instructed to all units 60, and the CPUs of these units each hold the received instructions (mode data).

The CPU 14 of the unit 10 then returns to step 24 in FIG. 13b and proceeds through step 24 to step 25, where the data in the previous operation board register POBR is
As a result of the previous execution of step 26, the data matches the data in the operation board register OBR, so the process proceeds from step 25 to step 33.

In step 33, all the indicator lights on the abnormality display panel 33 are turned off, the standby indicator lamp on the operation board 12 is turned off, and the ready indicator lamp is turned on. Next, a ready signal is output and set to the copying machine 800 (34). Then, the process returns to step 5 in FIG.
Wait for the key-in of step 2 6. When the start signal arrives from the copying machine 800 (6), refer to the ready/standby bit of the operation board register OBR (35). If it is 1, normal operation is possible, so the unit 20 to A start signal is sequentially transmitted to 60 at a predetermined timing (37).

The process then proceeds to read the status of the next step. unit 2
When each of 0 to 60 receives a start signal, it starts driving the conveying roller and waits for paper to arrive at each sensor. When paper arrives, predetermined control operations are initiated.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 20 waits (
If the CPU 14 of the unit 10 reads this in step 14 of FIG. 13b and proceeds to the abnormality processing (15) of the unit 20, in this abnormality processing, first the operation board register OBR is Refers to the copying machine input bit (151). If it is 1, data has been received from the copying machine 800 and sheet processing has not yet started or has already started, so the copying machine 800
An abnormality (standby) is transmitted to (152). Then, the ready/standby bit of the OBR is set to 0 indicating that the operation is disabled, the ready indicator light on the operation board 12 is turned off, and the standby indicator light is turned on (153), and then abnormal data is received from the unit 154 (154). , if the abnormal data indicates a paper jam, the abnormal display panel 1 corresponds to the position data.
Turn on the indicator light above 3 (156).

When the abnormal data indicates that the paper jam is not a paper jam, all indicator lights associated with the abnormal mechanism unit on the display panel 13 are turned on (157). Then, the process returns to the state reading after step 5 in FIG. 13a.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 30 waits (
If the unit 10 is unable to process) or is on standby, the CPtJ 14 of the unit IO reads this in step 16 of FIG. 13b and proceeds to abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15).

However, the unit 20 in (is) is read as the unit 30.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 40 waits (
If the CPU 14 of the unit IO reads this in step 18 of FIG. 13b and proceeds to the abnormality processing (19) of the unit 40, this abnormality processing (19) is the same as the above-mentioned abnormality processing. This is the same as (15).

However, unit 20 in (15) should be read as unit 40.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 50 waits (
If the CPU 14 of the unit 10 reads this in step 20 of FIG. 13b and proceeds to the abnormality processing (31) of the unit 50, this abnormality processing (21) is the same as the above-mentioned abnormality processing. This is the same as (15).

However, the unit 20 in (15) should be read as the unit 50.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 60 waits (
If the CPU 14 of the unit 10 reads this in step 22 of FIG. 13b and proceeds to the abnormality processing (23) of the unit 60, this abnormality processing (23) is the same as the above-mentioned abnormality processing. This is the same as (15).

However, the unit 20 in (15) should be read as the unit 60.

The operation of the vertical folding mechanism unit 100 and the operation of the 90@turn mechanism unit 200 brought about by the vertical folding & 906 turn control unit 20 have been described in their respective mechanism descriptions. Therefore, since the explanation of the control operation of this unit 20 is redundant, it will be omitted here.

Further, the operation of the blade folding mechanism unit 300 brought about by the blade spar control unit 30 has been explained in the mechanical description of the unit 300. Therefore, this unit 3
Since the explanation of the control operation of 0 is redundant, it will be omitted here.

The control operations of the punch control unit 40 and the stamper control unit 50 will be described later.

The control operations of the vertical conveyance and discharge control unit 60 include driving the paper conveyance roller, paper jam detection, and gate claw 7.
12 positioning control, it is simple, and unit 6
Those skilled in the art can easily understand from the mechanism explanations of 00 and 700, so the explanation here will be omitted.

Next, the control operation of the microprocessor of the punch control unit 40 will be explained with reference to FIGS. 14a and 14b. See also FIG.

First, reference is made to FIG. 14a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) of the unit 40 executes initialization (40) and status reading (41). Note that during initialization, the signal line to the unit 10 is set to standby.

As a result of the status reading (41), if the sensor 478 or 480 detects paper (42), it means that there is some remaining paper, so a paper jam signal is sent to the unit 10 (43), and the switch 476 (FIG. 1) is activated. Read the status of. While vapor jam, steps 44-41-42-43-44-41-
I've been thinking... When the switch 476 is closed, it reads whether the switch 460 is open or closed, and if it is open,
Since the cutter 452 is not at the home position shown in FIG. 8, it waits. When the switch 476 is closed while the cutter 452 is at the home position, the process proceeds to steps 44-45-46, where the pulse motor 458 is energized to rotate normally and a timer Tam is set (46). Ta+
m is the time it takes for the cutter 452 to travel a distance slightly longer than the short side length of A2. When the timer Ta2 exceeds (47), the motor 458 is stopped (48), the motor 458 is reversely energized, and the timer Ta+s is set (50). Then, it waits for the switch 460 to close or the timer Ta Peng times out (51, 52), and switches 4
When 60 is closed, the cutter 452 has returned to its home position, so the motor 458 is stopped (56). switch 4
If the timer Tan expires without the cutter 60 being closed, the return of the cutter 452 is abnormal, so the motor 45
The CPU of the unit 40 remains in this abnormality standby state until the power is turned on again.

Now, if the switch 460 is closed and the motor 458 is stopped before the timer Tam times out (56)
, reads the state of switch 484 (57).

If the switch 484 is closed and the punch unit is not at the home position (A4 punch position) (the initial state when the power is turned on is the A4 punch position), the pulse motor 450 is activated to set the punch unit at the home position. is reversely energized and timer Tba is set (58
), Tba is when the punch unit moves from B5 punch position to A4
This is the time required to reach the punch position (home position).

When switch 484 is closed (59), motor 45
0 (62), and if Tba passes without the switch 484 being closed (60), there is a mechanical abnormality, so the motor 450 is stopped (61) and the process goes to abnormality standby (55).

When switch 484 is closed to stop the motor (62
), proceed to status reading 41. In the status reading 41, the sensor 47
If paper is not detected in any of the units 8 and 480 (42), the switch 460 is closed (49), and the switch 484 is closed (57), the unit 10 is in a normal standby state, so a ready message is sent to the unit 10 ( 63).

When ready is transmitted to the unit 10 (63), the unit waits for transmission from the unit 10 (64), and if there is a transmission, it is received (65). This transmission is the setting of the punch mode (30) in FIG. 13d.

Upon receiving the signal from unit 10 (65), the 14th
Proceeding to step 66 in Figure b, it is checked whether the signal is a start signal or not. If it is not a start signal, check whether it is data or not (
67), if it is data, the received data is stored in the mode register 68), and the content of the data in the mode register is referenced (69.70). The content is punch specified and B
If it is a plate, the pulse motor 450 is driven in normal rotation from the A4 punch position (home position shown in FIG. 8) to the 85 punch position and stopped at the B5 punch position (71). When it stops, it notifies the unit 10 that it is ready again (63). When there is no punch instruction or when using A version punch,
The unit 10 is immediately notified of the ready state (63).

When a start signal is received from the unit 10, all rollers are set to the driving state and the timer Ts is set.72)
, sensor 478 detects paper, or timer Ts
waits for timeout (73, 74). If Ts times out without paper arriving, it is assumed that there has been some kind of trouble in the mechanical units up to the punching mechanism unit 400, that there has been a change in the state of the copying machine that does not start copying, or that paper feeding has ended, and the roller 75) and send a standby message to the unit 10. 76) Proceed to status reading 41.

When this process is followed, the unit 400 is in the ready state, so immediately after that, in step 63, the unit 100 is ready.
The unit 10 then sends a ready signal to the unit 10 and waits for the start signal to arrive again from the unit 10.

Now, when the start signal arrives and the sensor 478 detects paper before the timer Ts times out (73), referring to the contents of the mode register (77.78), punching is instructed and when it is the A version, the solenoid 428 is energized. and raises the register 426 to the paper stop position (79). When punching is instructed and it is the B plate, the solenoid 424 is energized to raise the register 422 to the paper stop position (80). When punching is not instructed, solenoids 426 and 424 are not energized.

Now, when the solenoid 426 or 424 is energized, it waits for the sensor 480 to detect paper (&1), and when it detects paper, waits for the timing when the paper comes into contact with the register 426 or 422 (82, 83° 84.85). , the steel ball solenoids 418, 482 are energized to pull up the steel balls 419, 483 (86). This causes the paper to stop at the register 422 or in the stopped state at 422 . Next, the solenoid 438 is energized, and after a period of time for the punch rod to enter the hole 444, the solenoid 438 is de-energized to punch a hole in the paper (87). Next, all solenoids 428, 424° 418.
When the sensor 480 changes from paper detection to non-detection (when the punched paper passes through the sensor 480), set the timer Ts 72), and then refer to the detection state of the sensor 480 (89). Waiting for the arrival of paper (73)
.

When punching is not instructed, the process proceeds from step 77 to step 90-89-72, and while the sheets of paper arrive one after another, the rollers are continued to be driven and the punch is energized.

Do not energize the solenoid, etc. 'Next, 15a
The control operation of the microprocessor of the stamp control unit 50 will be explained with reference to the figure and FIG. 15b. 9th
See also Figure 15a.X11 Reference is first made to Figure 15a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) of the unit 50 executes initialization (91) and status reading (92). Then, when the sensor 598 detects paper (9
3) Send paper jam to unit 10 (94)
. Then, the state is read (92) and then the sensor 598 waits until the paper is not detected.

Now, if the sensor 598 does not detect paper in the status reading (92), the detection status of the sensor 536 is referred to (95).
. When the sensor 536 is in the light detection state, the standby printing tool is not at the home position, so the pulse motor 520
starts normal rotation bias and starts counting the amount of rotation (96
). Then, the state and rotation amount of the sensor 536 are read (97a, 98), and when the sensor 536 becomes light-shielded, the printing tool has reached the home position, so the motor 5
20 is stopped, and a stop restraining current is applied to the motor 520 (97b). If the rotation amount reaches one rotation without the sensor 536 being in the light shielding state, it is abnormal, so the motor 520
99), sends a mechanism abnormality message to the unit 10 (100), and waits until the power is cut off (101).

Now, if the sensor 536 is shielded from light, then the state of the sensor 547 is referred to (102). If the sensor 547 detects light (reflector plate 545), the second printing cylinder 541 (publisher printing surface) returns to the home page. in position.

If the sensor 547 does not detect light, the publisher printing surface 5
41 by one step (103). Do this like this: First, the solenoid 555 is energized and the arm 553 is
The latch claw at the tip of the latch is advanced to the base of the latch port 543, and the pulse motor 520 is first rotated in the reverse direction by a predetermined angle.Then, the energization of the solenoid 555 is cut off, and the pulse motor 520 is then rotated forward by the predetermined angle. energizing and motor 520
A stop restraining current is applied to. As a result, the second printing cylinder 5
41 is rotated 360' 15=72@, and the printing surface is advanced by one step. Sensor 536 has returned to its light-blocking state.

When the print surface feed of l steps is completed, the feed step counter is incremented by one count.

Compare the count value (feed step amount) with 4 (104
). If it is not 4, the state of the sensor 547 is referred to again, and if it is light-shielded, one more printing surface feed is performed. In this way, the printing surface is fed one step at a time until the sensor 547 is blocked from light. When the sensor 547 is shielded from light, the second print Wi 4541 is set to the home position (the first publisher is the print position).

If the sensor 547 does not block the light even after four step feeds, it is determined that there is a mechanism abnormality and the mechanism abnormality is transmitted to the second unit 10. The process proceeds to 100) abnormality standby (lO1).

When the second printing cylinder 541 is at the home position, next, the home position determination of the first printing cylinder (drawing type/character side) 540 is performed, and if there is no home position setting, the home position setting is performed in the same way as the home position setting of the second printing cylinder 541 (10
5,106,107).

When the first print @ 540 is also at the home position, it sends a ready signal to the unit 10 (108), waits for the arrival of a signal from the unit to (109), and receives the signal from the unit 10 (110). .

Next, the process proceeds to steps 111 and 112 in FIG. 15b, and if the received signal is data, the data is stored in the mode register (113), and the content of this data is referenced (114).
), if a stamp is specified, the stamp specified publisher's stamp data (first to fifth publisher's stamp numbers) and the current location! (115
), and if they do not match, the second printing cylinder 541 is driven in steps (116). This one-person step driving operation is the same as that in step 103.

For example, if the data specifies the third printing surface.

3-1 = 2, drives 2 steps and stores 3 in the position register. The current position is the third printing surface (position register =
When the first printing surface is specified in 3), 1-3=-2
, 5-2=3, 3-step driving is performed. Next, compare the drawing egg data (1st to 5th drawing seed mark numbers) and the current position (1st drawing egg number = 1) (115), and if they do not match, the first printing Step drive the cylinder 540 (11g). This printing surface setting is also similar to the setting operation in step 116.

When the setting of the printing surface is completed, a ready signal is sent to the unit 1o (108), and the process waits for a start signal to arrive from the unit 1o (109, 110° 111).

When the start signal is received from the unit 10, the roller 5
82 to the driving state and set the timer Ts to 1.
19) Wait until the sensor 598 detects paper or the timer Ts times out (120, 121)
). If Ts times out without paper arriving, it is assumed that there has been some kind of trouble in the mechanical units up to the stamp mechanism unit 500, that there has been a change in the state of the copying machine 800 that does not start copying, or that the paper feeding has ended. 122) and send a standby message to the unit 10 123).
, proceed to status reading 92. When you go through this process,
Since the unit 500 is in the ready state, immediately after that, in step 108, it transmits a ready signal to the unit 10-10, and waits for the start signal to arrive from the unit 10 again.

Now, when the start signal arrives and the sensor 598 detects paper before the timer Ts times out (120), refer to the contents of the mode register (124), and if a stamp is specified, the stamp position data is stored in the counter. The corresponding number of timing pulses is set, and down-counting of the pulses of the encoder 730 is started (125). Then, it waits for the count value to become 0 (126). When the count value reaches O, the pulse motor 520 is activated by the encoder 730.
The motor is energized for normal rotation in synchronization with the pulse of the motor, and starts counting the amount of rotation of the motor (127).

When the drive amount reaches the predetermined value pv, the printing surface has arrived just in front of the roller 572, so the solenoid 128 is energized to pull up the roller 572 (129). This starts stamping.

Thereafter, the motor 520 continues to be energized for normal rotation, and the sensor 5
When 36 is blocked from light (130), the printing tool has returned to the home position, so the motor 520 is stopped and the solenoid 57
8 is cut off, and a stop restraining current is applied to the motor 520 (131). Note that when the stamp is not instructed, the motor 520 is not energized and the solenoid 57 is not energized.
8 is also not energized.

Figure 15c shows the stamped image. Among the printing positions on paper, the position from the leading edge of the paper in the feeding direction is step 12
The print position in the direction perpendicular to the feeding direction of the 0 paper determined by the value set in the counter in step 5 is determined by the position of the base frame 502 in the perpendicular direction.

Note that cutters 223, 376, and 452 are driven when switches 237, 390, and 476 are closed, respectively, but these are automatically driven when a paper jam spanning between units is detected. You may also do so. For example, when the control unit 10 is notified of both a paper discharge section jam of the mechanism unit 100 and a paper reception section jam of the mechanism unit 200, the control unit 10 instructs the control unit 20 to drive the cutter 223, and When both the paper ejection section jam of the unit 200 and the paper reception section jam of the mechanical unit 300 are notified, the control unit 30 is notified of the cutter 37
6 to drive the mechanism unit 30 to the control unit IO.
When a paper discharge section jam of 0 and a paper receiving section jam of the mechanical unit 400 are both notified, the control unit 40 is instructed to drive the cutter 376. Alternatively, each of the control units 20, 30, and 40 may determine an inter-unit paper jam and independently and automatically drive the cutter.

Next, the advantages of the embodiments described above will be summarized and explained.

(1) Edge folding of paper of various sizes and orientations (3 corners)
Corner folds), vertical folds, cross strings, punches and stamps are performed automatically and at high speed. It is possible to continuously process a large amount of paper, and manual labor such as paper folding is omitted. These processes can be set according to standards.

(2) The processing mechanism is divided into units, and each unit can be pulled out to perform jammed paper removal, inspection, repair, etc. Each unit is equipped with a grip for manual paper ejection, so
Jammed paper can be removed in unit units.

(3) It is equipped with a cutter that automatically cuts jammed paper spanning two units, and can prevent the jammed paper from becoming a severe jam due to unit drawer. Paper removal is easy.

(3) In the vertical folding mechanism unit 100, a conveyance path for paper that does not require vertical folding and a conveyance path for paper that requires vertical folding are separated,
A paper guide gate is arranged between the two, and paper that is not vertically folded is directly sent to the next unit, so the paper feeding speed can be extremely high, and the jam rate is reduced. Switching between the conveyance path for paper that does not require vertical folding and the conveyance path for paper that requires vertical folding is simple, and both the single mechanism and the paper feed control operation are simple.

(4) Paper conveyance path that does not require vertical folding (rollers 104°, 108
), and a vertical folding paper feed path (vertical folding roller 116°118.12
0) is in a horizontal-chocho shape, the subsequent seat posture processing is easy, and the vertical folding mechanism unit 100 is made compact.

(5) In the vertical folding mechanism unit 100, the versatility of the zero paper size is high as it is possible to select the vertical folding of A version and B version by simply adding a movable register.

(6) End face fold (corner triangular fold) is punched out 138 and folded plate 1
97, and the folded shape is more accurate than when using rollers or the like. Switching between the A version and the B version is performed only by a movable register, and paper feed control is extremely simple compared to the case where rollers or the like are used.

(7) The folded plate has a paper edge in the shape of a "C" on a plane, and a corner of the paper is formed on the straight part of the "C".The straight part of the character forms a corner of the paper. Since it is shaped so that one side is bent by the curved part, it is difficult for the entire paper to shift, and moreover, it ensures folding in a fixed shape.

8) In the 90° turn mechanism unit 200.

A plurality of rollers with different linear speeds are arranged in a direction perpendicular to the paper feeding direction, and a steel ball solenoid is arranged above them.
Since the steel ball is pulled up from the paper and dropped onto the paper by turning on and off the steel ball solenoid, it is easy to switch between direct feeding of paper and 90" turn, and the 90" turn is easy.
There is no need to separate the direct feeding path for paper 0, which allows for smooth turns, and the 90@turn path, and the unit 200 is arranged with a register that can move forward and backward at the paper feeding port where the unit 200 is compact. Since the position is also adjusted (correcting the misalignment) at that point, the feeding position of one sheet is adjusted, and the subsequent position of the paper to the mechanical unit becomes accurate.

In the 90° turn mechanism unit 200 as well, the paper receiving path is shaped like a horizontal block, and separate receivers are placed for vertically folded blank paper and vertically folded paper, so that both of them are aligned and sent out to a common outlet. This simplifies the handling of paper in the mechanical unit. Since both the vertically folded paper feed roller and the 90° turn roller are used to feed the paper together with a steel ball solenoid, single paper feed selection and control can be performed easily and smoothly.

(9) In the blade folding mechanism unit 300, the folding rollers 318, 320, 322 for the first horizontal folding and the folding rollers 320, 322, 324 for the second horizontal folding are arranged at the same position,
Folding rollers 320 and 322 are used in common for the first horizontal folding and the second horizontal folding, and the paper input conveyance path (303) and the first horizontal folding conveyance path (305
), the second horizontal folding conveyance path (307), and the paper delivery conveyance path (3
09) are arranged crisscrossing around these crossbeam rollers.

Moreover, since the angle between the paper input conveyance path (303) and the second horizontal folding conveyance path is a small angle, and the angle between the first horizontal folding conveyance path (305) and the paper output conveyance path (309) is a small angle, A first transverse fold and a second transverse fold are quickly made in the space.

(lO) Whether or not to make the first horizontal turn is determined by the gate pawl 324 and the solenoid 332 that drives it.

These are few mechanisms and occupy a small space. Similarly, whether or not to make the second horizontal turn is set by the gate pawl 350 and the solenoid 358 that drives it.
These are also small mechanisms and occupy a small space.

The gate claw 324 is attached to the shaft of the roller 318, and the gate claw 350 is attached to the shaft of the roller 318.
are pivotally mounted on the shaft of the roller 320, and driving these to the transverse folding position and retracting from the transverse folding position is simple, and the control is also simple, as it only involves turning on and off a solenoid.

(11) The first horizontally folding conveyance path (305) and the second horizontally folding conveyance path (
307) are each equipped with movable registers and fixed registers for various paper sizes and various folds, and automatically select many types of folds of many sizes as shown in FIGS. 3a and 3b. . Since the movable register is solenoid driven, selection and setting of the register (size and fold) is easy.

(12) Arm 3 that drives the gate claws 324 and 350
30. When 354 is equipped with the engagers 331 and 355, the latch claws 348 and 368 are fixed to the movable register, and the solenoids 332 and 358 are energized to drive the gate claws 324 and 350 to the non-folding setting position.

Since the engagers 331 and 355 engage with the latch claws 348 and 368 to lock the arms 330 and 354 by the weight of the movable register, the solenoids 332 and 35
8 continuous energization is not necessary.

The lock is released by momentarily energizing the movable register drive solenoids 346, 370.

When driving the gate pawl, there is no crossbeam and the movable register does not need to be driven, and when retracting (unlocking) the gate pawl, there is a crossbeam and there is a high possibility that the movable register needs to be driven. The gate pawl latch mechanism, the latch, and the release operation rationally utilize the originally required mechanical elements and the required operations.

(13) Flexible members 305 c and 307 c (seventh
(Fig. b) are pasted to prevent the paper from being scratched and prevent paper jams at the crossbeam rollers. Also, the angle between the paper input conveyance path (303) and the second horizontal folding conveyance path is set to a small angle, and the angle between the first horizontal folding conveyance path (305) and the paper output conveyance path (309) is set to a small angle.
It is useful to make the angle small.

(14) All the rollers in the paper input conveyance path (303) are designed to feed the paper in cooperation with the steel balls above them, and the steel balls are pivotally connected to an opening/closing plate that can be opened and closed with a hinge. . Therefore, the work of removing jammed paper is easy. In addition, it prevents uneven tension from being applied to the paper being pulled by the crossbeam rollers. This helps with horizontal folding along precise lines. Further, it is useful for changing the paper feeding speed (changing from low to high) between the paper input rollers 304 and 308 and the paper input conveyance path (303).

(15) The wheels of the rollers 410, 412, and 414 are tilted, so that the paper is brought to the fixed register 460 until it reaches just below the punch tip, and the tip is placed in a movable register according to the paper size. can be arranged. Therefore, the punch holes are neatly arranged on a line parallel to one side of the paper, and the punch positions are accurate.

(16) 'In the haunch mechanism unit 400, the paper is stopped by a movable register and the steel ball solenoid is energized to cut off the feeding force to the paper and punch, so that the punch hole is punched while the paper is stopped. Even at high-speed paper transport settings, the punched holes will not tear or deform.

Punch holes are punched at positions appropriate for the paper size. Based on the paper size, posture, and signal indicating whether punching is necessary, it is automatically determined whether or not to punch, and when punching is to be performed, the punching position is automatically set.

(17) The stamp mechanism unit 500 includes polygonal printing cylinders 540, 541, which are connected to a solenoid 554,
555 and the printing tool drive motor 520, there are fewer mechanical elements for updating the printing surface, making it compact.

(18) Since the printing MS40, 541 has a polygonal shape and is installed eccentrically from the printing tool rotation axis 510, 528, the printing set at the printing position during the printing tool rotation (one rotation of 510) Only the front side is stamped. There are no stains on the paper. Note that the printing rubber supporting sides of the printing cylinders 540 and 541 do not have to be flat, but may be curved surfaces curved in an arc shape.

(19) The stamp roller 572 can move forward and backward and is driven by a solenoid 578, and at the appropriate position the paper is pushed up slightly from the conveying surface toward the free rotation wheel, and at the retracted position it does not contact the printing surface. Therefore, even if the printing tool rotates, if the stamp roller 572 is in the retracted position,
The roller 572 is not stained with ink.

(20) The printing tool drive motor 520 is a pulse motor, and a stop restraint current is applied during the stoppage, so that the printing tool can be reliably stopped and restrained (positioned).

(21) The printing tool drive motor 520 is a pulse motor, and is driven in synchronization with the paper feed synchronization pulse (encoder pulse) during stamping, so that the printing tool can be accurately and easily driven in synchronization with the paper.

(22) The position of the base frame can be manually adjusted in a direction perpendicular to the paper feed direction, and the stamp position in this direction can be adjusted and set. The stamp position in the paper feed direction is automatically determined according to an electrical signal, and It can be set with .

(23) The ink roller 560 is removably attached to the base frame,
Further, the stamp mechanism unit 500 is a sheet processing machine 900.
Since it can be freely pulled out from the main body, it is easy to remove dust from the ink roller 560, supply new ink to the roller 560, etc.

(24) The date at the printing position of the printing tool can be changed in the manner shown in FIG. 9c by turning the manual rotary wheel 522 with the unit 500 pulled out. Mechanism unit 50
Since 0 can be withdrawn freely, changing this date is also relatively easy.

(25) The feeding direction of the processed paper can be selected.

This setting is also done electrically. Paper ejection in one of the two directions is performed by one solenoid 716 and gate pawl 712, and the mechanism and control are simple.

(26) Each of the control units is provided approximately corresponding to the mechanical unit classification, and an operation board control unit is provided, the operation board control unit is the main control unit, the other control units are the slave control units, and the paper size, posture,
Data indicating fold type, need for punching, need for stamping, stamp content, etc. is given to the operation board control unit from the operation board and/or a host such as a copying machine, and the operation board control unit determines the sheet processing mode and makes a decision. The processing mode of each slave control unit is determined based on the sheet processing mode determined, and this is sent to the slave control unit.

Therefore, the control operation of the slave control unit is relatively simple, and the slave control unit performs sheet processing control, paper jam determination and abnormality determination, and paper jam determination of the mechanical unit assigned to it.

All you have to do is stop the protection in the event of an abnormality and send it to the main control unit.The overall movement of the sheet processing machine 900 and the movement of each mechanical unit are consistent, allowing a quick response in the event of trouble, and the severity of the trouble. is prevented.

(27) If the signals and data obtained from the settings of the host such as the copying machine 800 overlap with the signals and data obtained from the settings of the operation board, the operation board control unit
The former is prioritized over the latter, and signals and data that cannot be obtained from the host are assumed to be obtained from the settings of the operation board, and the data that becomes the basis for determining the processing mode is prepared.

When the sheet processing machine 900 is connected to a host such as a copying machine 800, the data given from the host is more reliable, and processing should be started in response to a start signal from the host. Therefore, the above-mentioned signal and data processing is rational and there are few errors in judgment and processing. Also, the operations of the host and the sheet processing machine are synchronized or coordinated.

If the host is not connected, the sheet processing machine 900 operates in response to input from the operation board, so the sheet processing machine 900 can be used alone.

(2g) Based on upper fold data such as 4-fold, 2-fold, JIS fold, etc. and paper size data, the sheet processing machine 900
Fold in 2 vertically, fold in 2 JI8 vertically, and fold in 2 horizontally.

Since the lower fold types that need to be specified in the vertical folding mechanism unit 100 and the new blade mechanism unit 300, such as horizontal JIS folding, are automatically determined and automatically set,
There is no need for the operation board or host to be able to set a large number of lower fold types, and the operator can easily set the processing mode. Similarly, paper posture data and size data, as well as
Based on the upper fold data, 90° turn mechanism unit 2
Since the sheet processing machine 900 automatically determines whether or not a 90@turn is necessary, which needs to be specified at 00, and automatically sets it, the operator does not have to think about whether or not a 90@turn is necessary. There's no need to set it up.

(29) When viewed in the paper feeding direction, the paper feeding speed of the upstream mechanical unit is relatively low, and the paper feeding speed increases as the downstream mechanical unit approaches. The most upstream mechanical unit 100 has a speed comparable to the scheduled paper feed ratio speed of the host. Since the speed is set in this way, the sheet processing machine 9
00, the number of sheets existing at one time is as small as possible, and the number of sheets remaining at the time of paper jam is reduced. Also during paper jam.

Notification to the host is quick, and unnecessary paper is reduced. In addition, idle time for feeding paper to downstream equipment such as a sorter becomes longer, and the operating margin of the equipment becomes larger.
