Abstract

PURPOSE:To provide a plural number of constituting printing surfaces and to automatically set one of these printing surfaces at a stamping position by energizing a motor for rotation synchronously with the feeding speed of an object to be stamped. CONSTITUTION:A pulse motor is started for its rotation in the normal direction at a fixed accelerating pattern and the counting of the rotation volume is started, and at the same time, the time required for one rotation of a rotary encoder of a delivery mechanism unit 700 is measured. When a driving volume reaches to a fixed amount PV, the printing surface comes immediately before a roller 572, and an electricity is applied to a solenoid and the roller 572 is raised. Thus, stamping starts. Thereafter, the motor 520 is continuously energized for its normal rotation, and if a sensor 536 is shaded, the printing instrument returns to the home position, and therefore, the motor 520 is stopped and the solenoid 578 is turned off, and the locking current of the level lower than the rotation energizing current is applied to the motor 520. By this, the rotation member is stopped and locked at the home position, and a position blurring is prevented.

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 the flat side, 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 paper feeding direction 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 paper. As described later,
This timing is set by an electrical signal and is done automatically.

The ink roller 560 is pivotally mounted to a support frame 560, as shown in FIG. 5b. The slider 5 is mounted on the support frame 584.
86 (two pieces) are mounted so as to be movable in the direction of arrow 593 and the opposite direction. A compression coil spring 589 is interposed between the two sliders 586, and applies a force to separate the sliders. A notch 590 for pin engagement is formed in the support frame 560, and a pin guide hole 587 and a pin guide groove 588 continuous with the pin guide hole 587 are formed in the slider 586. In the ink roller unit shown in FIG. 5b, the sides Fi 504 and 506 of the base frame 502 are moved in a state where the spring 589 is compressed and both sliders 586 are brought close to each other.
Align notch 590 and pin guide hole 587 with pins 592 and 591 fixed to support arm (not shown) fixed to support frame 584 to the right in FIG. 5b,
Release the rear slider 586 and release the spring 58.
By expanding both sliders 586 with a force of 9, the base frame 5
It is installed on 02. The mounted position is shown in Figure 5a. In this way, the ink roller 560 can be attached to and detached from the base frame 502.

After paper is detected by sensor 598, pulse motor 52
0 in normal rotation at a speed synchronized with the moving speed of the paper, and the printing tool No. 1. The second support plate 512t526 is rotated counterclockwise, and just before the printed surface faces the roller 574, the solenoid 578 is energized to pull up the roller 572, and when one side of the printed surface passes the roller 572, the solenoid 578 is energized. One printing is performed by cutting off and lowering the roller 572. Note that while the printed surface moves from the standby position (home position) shown in FIG. 5a onto 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 a stamp image is shown in FIG. 8c.

An upper cover 594 is attached to the base frame 502. A state in which the upper cover 594 is attached is shown in FIG. 5c. Note that FIG. 5c shows a state in which the manual rotating wheel 522 is rotated and the date changing ring portion of the date stamper 556 is moved directly below the opening 594 of the cover 594. The date can be changed in this state. In addition, you can set the date manually like this.
However, the 1st date on the base frame 502 and the date on the stamper 556 are provided in a position that can face the changing wheel, and a roller for changing the date is provided so that it can be driven forward and backward by a solenoid or the like.
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 wheel, and drive the roller to rotate. good. In this way, the date can be changed automatically. Further, a driver groove may be coupled to the base frame 502 to automatically drive the paper in a direction perpendicular to the paper feeding direction.

7a to 7d show the control operation of the microprocessor 14 of the operation board control unit 10. The control operation of the operation board control unit 10, that is, the control operation of the microprocessor 14 will be explained with reference to these drawings.

Referring first to FIG. 7a. When the IL source 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), and timers (program timers). etc. (Step 1). In the following, the word "r step" will be omitted in parentheses, and only the step symbol will be shown.

After completing the initialization, the CPU 14 reads the status. First, it is checked whether there is a read flag (2
), since initialization has just been completed at this point, there is no read flag, so proceed to step 3 and set standard data in the operation board register. IM semi-data: Paper size: A4 Digit selection: Unfolded portrait/horizontal orientation: Landscape Stamp position: Om++ Publisher:
1st design (1st publication year) Drawing type: Cause (1st drawing type) Punch selection: No punch paper ejection selection lights up. In this state, on the operation board 12, standby (this is set at initialization),
A4. No folds, horizontal, Omm, no punch, 1st design,
Indicator lights are lit to indicate the tray and cause.

In Figure 6b, 3 assigned to the operating board register OBR
Byte memory area (an area of the internal RAM of the CPU 14)
Indicates the writing position of data to be temporarily written to.

After writing the standard data to the operation board register OBR, a read flag is set (4) 6 Next, referring to the state of the board that receives the input signal from the copying machine 800, the copying machine 80
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 for which memory bits are assigned to the operation board register OBR is updated and written to the operation board register OBR. When such update writing is performed, the operation board register O
Write 1 to the bit indicated as the copying machine input bit of BR. This 1 indicates that the copying machine 800 has given an instruction to the sheet processing machine 900 regarding 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 12 key-ins. If the key-in is by 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. @Work When the key switch 12a is closed once when the size designation bit of the board register OBR is B5, the size designation bit is updated to data indicating A2, the B5 indicator light is turned off, and the A2 indicator light is turned off. Light. In this way, each time the size indication key switch 12a is closed, the lighting of one 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 0; if size data has already been received, step 11
-12-■, the cp'U14 performs the same operation in response to a key-in by the key switches 12c to 12h, without updating data or updating the display in response to the key-in.

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 12i 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. 7b, the signal level of the signal reception port from the unit 20 is referred to to see whether it is ready (paper can be accepted) or not (standby second class cannot be accepted).

If the vertical fold & 9o turn control unit 20 is ready in step 14 of FIG. 7b, the unit 3 is ready in step 16.
Check whether 0 is ready or not. If the vane spar control unit 30 is ready, it is checked in step 18 whether the unit 40 is ready.

If the punch control unit 40 is ready, step 2
0, it is checked whether the unit 50 is ready. If the stamper control unit 50 is ready, it is checked in step 22 whether the unit 60 is ready. When the vertical conveyance & discharge 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 OBH to 1 indicating processing possible L (24); The data in the operation board register OBR and the data in the previous operation board register POBR are compared (25). Note that since the previous operation board register OBR has been cleared during the initialization in step 1, the contents of the two do not match when the process proceeds to step 25 for the first time. This applies to each unit 20 to 60 in steps 27 and below, which will be described later.
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. 7c.

Setting the A version processing mode to the unit 20 in FIG. 7C (
27), 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).

If it indicates the side, refer to the digit selection bit of OBR (282), and if it is unfolded, unit 20
The A3/horizontal/passing mode is transmitted to (283). If there is an emergency, A3.90@turn mode is sent to the unit 20.

When the size is A4 (285), refer to the height/width specification bit (286), and if it indicates the width (286),
86), transmits the A4/horizontal/passing mode to the unit 20 (287). Unit 288 if it does not indicate the side
The A4/90'' turn mode is sent to (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 85, 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. 7d. In this step 29, first, the digit selection bit of the operation board register OBR is referred to (291, 292.2'94). If there is no fold, size data is attached and the passage is transmitted to the unit 30 (295). In the case of 4-fold, 2-fold, and JIS fold, the data of the size designation bit and the data of the digit selection bit of the operation board register OBR are transmitted to the unit 30 (293, 296). That's all for units 10 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 blade folding mode setting (29), the CPU 14 of the unit 10 sets the punching mode (30).

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 sends a non-punch mode to unit 40.

After completing the punch mode setting (30), the CPU 14 of the unit 10 sets the stamp mode (31).

In this case, the stamp selection focus of the operation board register OBR is referred to (312), and if it is 1 indicating a stamp, the unit 50 is informed.

Transmit the data of the stamp selection bit, stamp position bit, publisher selection bit, and drawing type selection bit of OBR (3L3). If the stamp selection bit is 0, a non-stamp signal is transmitted to the unit 50.

After completing the stamp mode setting (31), 2 knits 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
The CPU 14 of the unit 10, which holds the received instructions (mode data), returns to step 24 in FIG. 7b, and through step 24 Proceed to step 25. Here, the data in the previous operation board register POBR matches the data in the operation board register OBR due to the previous execution of step 26, so the process advances 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.6 Next, a ready signal is output and set to the copying machine 800 (34), and Returning to step 5 in FIG. 7a, the arrival of the signal from the copying machine 800 and the operation board 12
Wait for key-in.

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, the blade is operating normally, so the units 20 to 60 are activated at a predetermined timing. The start signals are sequentially transmitted (37).

The process then proceeds to read the status of the next step. unit 2
Each of 0 to 60 starts driving the conveying roller when receiving a start signal, and when the 0 paper arrives at each sensor, a predetermined control operation is started.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 20 waits (
If the unit 10 is unable to process (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 14 of FIG. 7b and proceeds to abnormality processing (15) of the unit 20. In this abnormal process, first refer to the copier input bit of the operation board register OBR (L5L) - if it is 1, data has been received from the copier 800 and sheet processing has not yet started or has already started. Therefore, it sends an abnormality (standby) signal to the copying machine 800 (152), sets the OBR ready/standby bit to O indicating that it cannot operate, turns off the ready indicator light on the operation board 12, and turns on the standby indicator light. (153). Next, the abnormality data is received from the unit 154 (154), and if the abnormal data indicates a paper jam, the abnormality display panel 13 corresponding to the position data is displayed.
Turn on the upper indicator light (156).

If 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 (L57). Then, the process returns to the state reading after step 5 in FIG. 7a.

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 (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 16 of FIG. 7b and proceeds to abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15).

However, unit 20 in (15) should be read as 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 unit 10 is unable to process (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 18 of FIG. 7b and proceeds to abnormality processing (19) of the unit 40. This abnormality processing (19) is similar to the above-mentioned abnormality processing (15).

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

Before or after the control unit IO 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. 7b and proceeds to the abnormality processing (31) of the unit 50, this abnormality processing (21) is the same as the above-mentioned abnormality processing. It is the same as (15), however, the unit 20 in (15) is 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. 7b 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 fold & 901 turn control unit 20 have been explained in the respective mechanism descriptions. Therefore, the control operation of this unit 20 will be explained below. The explanation will be omitted here as it will be redundant.

Further, the operation of the blade folding mechanism unit 300 brought about by the single blade spar control unit 30 has been explained in the mechanism description of the 22 points 300. Therefore, this unit 3
Since the explanation of the control operation of o 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 stamp control unit 50 will be explained with reference to FIGS. 8a and 8b. See also Figure 5a.

Referring first to FIG. 8a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) of the unit 50
performs initialization (91) and reads status (92). Then, when the sensor 598 detects paper (93
), sending a 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 printing tool of the stamper 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 of the sensor 536 and the amount of rotation 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 the motor 520 is energized with a stop restraining current at a lower level than the rotational energizing current (97b), so that the motor 520 is locked while it is stopped, and no displacement occurs. .

If the rotation amount reaches one rotation without the sensor 536 being in the light shielding state, it is abnormal and the motor 520 should be stopped.99
), transmits a mechanism abnormality to the unit 10 (100), and waits until the power is cut off (101).

Now, if the sensor 536 is shielded from light, the primary refers to the state of the sensor 547 (102), and if the sensor 547 detects light (reflector 545), the second print 11M541 (issuer print surface) is at the home position. It is in.

If the sensor 547 does not detect light, the publisher printing surface 5
41 by one step (103), this is done as follows. 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, then the pulse motor 520 is reversed by a predetermined angle, the solenoid 555 is de-energized, and the pulse motor 520 is first 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 by 360''15=72', and the printed surface is advanced by one step. The sensor 536 has returned to the light shielding 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 advanced step by step until the sensor 547 is blocked from light. When the sensor 547 is blocked from light, the second printing cylinder 541 is moved to the home position (the first printing source is set to the printing position). Become.

Note that if the sensor 547 does not block light even after four step feeds, it is determined that one mechanism is abnormal and a mechanism abnormality is sent to the unit 10 (100). The process goes to abnormality standby (101).

When the second printing cylinder 541 is at the home position, next the home position determination of the first printing cylinder (drawing type/egg surface) 540 is performed, and if it is not present, the Baum 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 printing cylinder 540 is also at the home position, it sends a ready message to the unit 10 (108), waits for the arrival of a signal from the unit IO (109), and receives the signal when it is sent from the unit 10 (110).

Next, the process proceeds to steps 111 and 112 in FIG. 8b, 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 issuer year data for which the stamp was specified (numbers of the first to fifth issuer's stamps) and the current location (
The first publication year number = 1) is compared (115), and if the two do not match, the second printing [541] is step-driven (116). The one-step drive amount operation of this step drive is the same as that in step 103. For example, if the data specifies the third printing surface, 3-1=2, and 2
Step drive and store 3 in the position register. When the current position is the third printing surface (position register = 3) and the first printing surface is specified, 1-3=-2, 5-2=3, and 3
Step driven. Next, the drawing egg data (1st to 5th drawing seed mark numbers) and the current position (1st drawing egg number = 1)
(115), and the two do not match.

The first printing cylinder 540 is driven in steps (118).

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 10 (108), and the process waits for a start signal to arrive from the unit 10 (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 IO 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, a ready signal is transmitted to the unit 10, and the unit 500 waits for a 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, the encoder 730 starts counting down the pulses (125), and 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).

The contents of this pulse motor rotation energizing subroutine 127 will now be described in detail.

First, forward rotation of the pulse motor is started in a predetermined acceleration pattern, and counting of the amount of forward rotation is started, and at the same time, the time required for one rotation of the rotary encoder of the paper ejection mechanism unit 700 is measured. Note that the paper feed speed of the paper discharge mechanism unit 700 and the paper feed speed of the stamp mechanism unit 500 are set to be the same speed. To measure this time, set a 0.6m5ec timer until it counts up the number of pulses (slits) generated during one rotation of the rotary encoder, and when the timer exceeds the timer, count up the time counter by 1. This is done by resetting the 0,6m5ec timer.

The content of the time counter when the value of the rotary encoder generated pulse number counter reaches the value for one rotation is the feed rate (
To be exact, it shows its reciprocal). When the feed rate data is obtained, the timer value associated with the feed rate is read from the ROM and set in the register. When the acceleration is finished, the timer value is set in the timer register, and when the time is over, the energizing phase signal of the pulse motor is switched to the next one.

Also set in the timer register. This behavior.

Repeat until the contents of the forward rotation amount counter reach Pv.

When the forward rotation drive amount reaches PV, this subroutine 127 is exited.

Now, when the driving amount reaches the predetermined value Pv, the printing surface becomes
72, the solenoid 128 is energized to pull up the roller 572 (129), thereby starting 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 at a lower level than the rotational energizing current is applied to the motor 520 (131). As a result, the rotating member is stopped and locked at the home position, and no displacement occurs. Note that when stamping is not instructed, the motor 520 is not energized to rotate, and the solenoid 578 is energized after the sensor 598 detects paper. As solenoid 578 is energized, roller 572
contacts the free rotating wheels 514, 532, and the roller 572 is rotating (it has been rotating together with the roller 582 since the start), so the incoming paper is sent out by the roller 572 and the free rotating wheels 514, 532. Rollers 580, 582
and then sent to the next vertical transport unit.

Figure 8c 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 125
It is determined by the value set in the counter in . What is the printing position in the direction perpendicular to the paper feed direction?

It is determined by the position of the base frame 502 in the orthogonal direction.

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

(1) 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.

(2) The stamp mechanism unit 500 includes polygonal printing sides 540, 541, which are connected by solenoids 554.
55 and the printing tool drive motor 520, there are fewer mechanical elements for updating the printing surface, making it compact.

(3) Since the printing sides 540 and 541 are polygonal and are installed eccentrically from the printing co-rotation shafts 510 and 528, the printing position is set during the printing tool rotation (one rotation of 510). Only the printed side is stamped. There are no stains on the paper. In addition, the printing rubber supporting side on the printing side 540° 541 is
Even if it's not flat.

It may be an arcuate curved surface.

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

(5) The printing tool drive motor 520 is a pulse motor,
Since the stop restraint current is applied during the stop, the stop restraint (positioning) of the printing tool is reliable.

(6) The printing tool drive motor 520 is a pulse motor,
Paper feed synchronization pulse (encoder pulse) when stamping
Since the printing tool is driven in synchronization with the paper, the printing tool can be accurately and easily driven in synchronization with the paper.

(7) The position of the base frame can be manually adjusted in a direction perpendicular to the paper feeding 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 electrical signals and can be set using a switch.

(8) Since the ink roller 560 can be attached to and removed from the base frame, and the stamp mechanism unit 500 can be pulled out from the main body of the sheet processing machine 900, it is possible to remove dust from the ink roller 560, supply new ink to the roller 560, etc. It's easy.

(9) The date is printed on the printing tool, and the date is printed on unit 5.
With the 00 pulled out, turn the 1 manual rotation shaft 522,
It may be modified in the manner shown in FIG. 9c. Mechanism unit 500
Because it can be pulled out freely.

This date is also relatively easy to change.

(10) A control unit is provided, and an operation board control unit is provided, the operation board control unit is used as a main control unit, the control unit is used as a slave control unit, and data indicating whether or not a stamp is required, stamp contents, etc. is transmitted to and from the operation board and Or, the host such as a copying machine sends it to the operation board control unit, the operation board control unit determines the stamp processing mode, determines the processing mode of the slave control unit based on the determined processing mode, and transmits this to the slave control unit. send. 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 of the mechanism unit, and
All you have to do is stop the protection in the event of a jam or abnormality and send this to the main control unit. The movement of the entire processing machine 900 and the movement of the mechanical units are matched, allowing a quick response in the event of a problem and preventing the problem from becoming more serious.

(11) The operation board control unit is a host such as the copying machine 800! − Signals and data obtained under the setting state.

If the signals and data obtained under the operating board settings overlap, the former is prioritized over the latter and the processing mode is determined, assuming that signals and data that cannot be obtained from the host are obtained under the operating board settings. Prepare the underlying data.

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 signal and data processing described above is rational and there are few errors in judgment and processing.

Also, the operations of the host and the stamp device are synchronized or coordinated.

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