Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an automatic stamping device for automatically stamping paper and other materials, and more particularly to an automatic stamping device for sheet-like materials such as copy paper.

■Prior Art For example, in an automatic stamp device for a copying machine, a backup roller is placed opposite a cylindrical stamp drum to which printing rubber is attached. The printing rubber (stamp surface) has characters that do not need to be changed, and numbers that need to be changed, such as the date, must be stamped by hand with a separate date stamper.Some models have a removable stamp surface. Yes, but
When changing the stamp face, the work of attaching and removing the stamp face gets the hands dirty, and various parts of the automatic standber become dirty. Therefore, currently,
Even the removable ones are used as special machines that are fixed to a single stamp surface. Therefore, only documents to be stamped with a fixed stamp surface are fed into the automatic stamping device.

However, in the case where an automatic stamping device is coupled to a copier, printer, facsimile machine (referred to as a host), etc., and the paper sent from the host is selectively stamped (when instructed), the conventional device It is not possible to pass without a stamp, which causes various inconveniences.

For example, when an automatic stamp device is connected to a copying machine, it is preferable that whether or not to stamp is set by a key-in from the operation board or an instruction from the copying machine, and automatic selection between no stamp and stamp is possible.

■Purpose The present invention can uniformly pass a stamp object such as a piece of paper regardless of whether stamping is required, and can also stamp
It is an object of the present invention to provide an automatic stamping device that can selectively perform stamping.

■Configuration and ■Effects In order to achieve the above object, the present invention provides.

a stamp power motor; a rotating member rotationally driven by the motor; a printing member coupled to the rotating member; a rotating wheel pivotally connected to the rotating member; a roller facing the rotating shaft across the conveyance surface of the stamp object; It includes a pressing drive means for driving the roller in a direction to press it against the rotating shaft; and a control means for energizing the pressing driving means and pressing the roller against the rotating wheel without energizing the motor in a non-printing mode.

According to this, for example, when paper is fed without stamping, the roller is in contact with the rotating shaft, and since the roller is rotating, one sheet of paper is fed between the rotating shaft and the roller.

Since the stamp power motor does not rotate, no stamping is performed.

In a preferred embodiment of the present invention, the rotary wheel is a free rotary wheel pivotally connected to the drive shaft of the rotary member, and the roller is tiltably supported at its l-axis end, where it is connected to the rotary power system, and the other end is freely rotatable. The roller is supported by a drive arm so as to be able to reciprocate in the direction away from the rotation axis and in the opposite direction, and a solenoid is used as the contact drive means, and when energized, the drive arm is driven and the roller is brought into contact with the free rotation axis. shall be brought into contact with each other.

According to this, smooth stamping and direct paper feeding can be performed selectively with a relatively small number of mechanical elements and combinations.

Other objects and features of the invention will become apparent from the following description of preferred embodiments with reference to the drawings.

It is attached to 2. 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. 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. 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. The state in which the upper cover 594 is attached is shown in FIG. 5c. In FIG. 5c, the manual rotating wheel 522 is rotated and the date changing shaft of the stamper 556 is moved to a position directly below the opening 594 of the cover 594. Indicates the condition. The date can be changed in this state. Although the date is adjusted manually in this way, a roller for changing the date is placed on the base frame 502 in a position that can face the date changing axis of the date stamper 556 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.

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 IO, that is, the control operation of the microprocessor 14 will be explained with reference to these drawings.

Referring first to FIG. 7a. 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), and counters (program counters).
, timer (program timer), etc. (step 1). In the following, the word "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 at this point there is no read flag, since we have just finished initializing it.

Proceed to step 3 and set standard data in the operation board register. The standard data is: Paper size: A4 Digit selection: Unfolded portrait/horizontal orientation: Horizontal Stamp position: Omm Publisher: 1st design (1st publisher department) Drawing type: Temporary drawing (1st drawing type) Punch selection: This is a paper ejection selection without punching option. When this data set is completed, the indicator light corresponding to the data is lit accordingly. In this state, on the 8th board 12, standby (this is set at initialization),
A4. Indicator lights indicating each of folded, horizontal, Omm, no punch, first design, tray, and tentative design are lit.

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.

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
0, it is determined whether a signal is transmitted or not (5). When there is a transmission, it is received, the signal and data are read, and it is determined whether the signal is a start signal or not (6). If it is not a start signal, it is determined whether it is an end signal or not7).If it is not an end signal, it is data, so among the input data, data whose memory bit is assigned to the operation board register ○BR is stored in the operation board register. ○Write BR update. When such update writing is performed, the operation board register O
A 1 is written in a bit indicated as a copying machine input bit in BR. This 1 indicates that the copying machine 800 has given an instruction to the sheet processing machine 900 regarding how to process a 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. 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 0; if size data has already been received, step 11
-12-■, the data and display are not updated in response to the key-in. The 7 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 12i of the vibration board 12. However, when even part of the data is being received from the copying machine 800 (copying machine input bit of OBR = 1), the key-in of the start signal by closing the switch 12i is disabled in step 38. ing. 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 reading/data set are meaningful when a copying machine is not connected, and when connected to a copying machine that does not transmit all required data, and when the sheet processing machine 900 is connected to an external device (host ) is not connected, or if the host has insufficient functionality, use key-in to compensate.

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 If there is no key-in (9), the process proceeds to step 14 in FIG. ).

If the vertical fold & 90° 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 & 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 OBR to 1 indicating processing is possible24). Compare the data in board register OBR and the data in previous operation board register POBR (
25). Note that the pre-operation board register ○BR has been cleared during the initialization in step 1, so it is not necessary to use step 2 for the first time.
When proceeding to step 5, the contents of the two do not match. This means that processing mode data transfer to each unit 20 to 60 from step 27 to be described later 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 (
In step 27), first, the size is determined from the data of the size designation bit of the operation board register ○BR (271).

If the size is A2, next refer to the fold selection bit of OBR (272-276). If there is no fold, 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 transmitted to the unit 20 (277). Also, if it is a JIS fold,
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, refer to the vertical/horizontal designation bit of the OBR, and if it indicates vertical (280), transmit A3/vertical/passing mode to the unit 20 (281);
If it indicates the side, refer to the fold selection bit in OBR (282), and if it indicates no fold, unit 20
The A3/horizontal/passing mode is transmitted to (283). In some cases, the unit 20 is sent an 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), transmits the A4/horizontal/passing mode to the unit 20 (287). Unit 288 if it does not indicate the side
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. If A2 in step 27 is read as B-3, A3 as B4, and A4 as 85, the contents of step 28 will be obtained.

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 fold selection bit of the operation board register ○BR is referred to (291, 292, 294), and when there is no fold, size data is attached and a pass is transmitted to the unit 30 (295). In the case of four-fold, two-fold, and JIS fold, the data of the size designation bit and the data of the fold selection bit of the operation board register BR are transmitted to the unit 30 (293, 296). As described above, control operation mode instructions are given to the units 10 to 30 and set in the microprocessor of the unit 30.

After setting the blade folding mode (29), the unit 10 (
7) The CPU 14 sets the punch mode (3o).

In this case, refer to the size specification bit data, digit selection bit data, and punch selection bit data of the operation board register OBR (301 to 306, 3
08, 309), When the final size is A4 and punched, send A4/punch mode to unit 4o307), When the final size is B5 and punched, send B5/punch mode to unit 4031
0), otherwise the non-punch mode is set to unit 4.
Send to 0.

After completing the punch mode setting (3o), the CPU 14 of the unit IO sets the stamp mode (31).

In this, the stamp selection bit of the operating board register OBR is looked up (312) to the unit 50 if it is 1 indicating a stamp.

OBR stamp selection bit, stamp position bit,
The publisher selection bit and drawing type selection bit data are transmitted (313). If the stamp selection bit is 0,
Send 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. 7b, and proceeds through step 24 to step 25.

Here, the data of the previous operation board register POBR is changed to the operation board register O by the execution of the previous step 26.
Since it matches the BR data, steps 25 to 3
Proceed to step 3.

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 key-in.

When the start signal arrives from the copy asoo (6), refer to the ready/standby bit of the operation board register OBR (35). If it is 1, normal operation is possible, so the units 20 to 60 are sequentially sent at a predetermined timing. A start signal is transmitted to (37).

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

Control unit 10 starts units 20-60 I
- Units I~20 before or after giving the signal
is waiting (cannot be processed) or becomes waiting,
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 abnormality processing, first the operation board register OB
The copier input bit of R is referred to (151). That's 1
If so, data is received from the copying machine 800, and since sheet processing has not yet started or has already started, an abnormality (standby) is sent to the copying machine 800 (152). And O
The ready/standby bit of the BR is set to 0 indicating that the operation is disabled, the ready indicator light of the operation board 12 is turned off, and the standby indicator light is turned on (153). Next, abnormal data is received from the unit 154 (154), and if the abnormal data indicates a paper jam, an indicator light on the abnormal display panel 13 corresponding to the position data is turned on (156). Different: If the t data indicates that there is no paper jam, 1 display panel 1
3, all the indicator lights corresponding to the abnormal mechanism unit and at 4"L are turned on (157). Then, the process returns to the status reading from step 5 in FIG. 7a.

'0199 Before or after unit IO gives a start signal to units 20 to 60, if unit 30 is in standby (unable to process) or becomes standby, CPU 14 of unit IO executes step 16 in FIG. 7b. After reading this, the abnormality processing (17) to proceed to the abnormality processing (17) of the unit 30 is the same as 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, if the units 1 to 40 are on standby (unable to process) or are on standby, the CPU 14 of the unit 10 executes the steps in FIG. 7b. Read this at step 18 and proceed to abnormality processing of unit 40 (step 19). 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 10 gives the Star 1 signal to the units 20 to 60, if the unit 50 is on standby (incapable of processing) or becomes on standby, the CPU 14 of the unit IO executes the step of FIG. 7b. This is read in step 20, and the process proceeds to abnormality processing (31) of the unit 50. This abnormality processing (21) is similar to the above-mentioned abnormality processing (15).

However, unit 20 in (15) is read as unit 5o.

Before or after the control unit 10 gives the start signal to the units 20 to 6o, the unit 60 enters the wait 1 (
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 22 of FIG. 7b and proceeds to abnormality processing (23) of the unit 60. This abnormality processing (23) is similar to the above-mentioned abnormality processing (15)6
However, the unit 20 in (15) can be read as the unit 6o.

The operation of the longitudinal folding a-structure unit 100 and the operation of the 90' turn 4114it unit 200 provided by the longitudinal folding & 90m turn control unit 20 have been explained in the 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 explanation of the mechanism of the units 1 to 300. Therefore, the explanation of the control operation of this unit 30 will be omitted here since it will be redundant.

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

The control operations of the p1 conveyance and paper ejection control unit 60 include driving the paper conveyance roller, paper jam detection, and positioning control of the gate claw 712, and are simple and can be easily understood by those skilled in the art from the mechanical explanation of the units 600 and 700. Since it can be easily understood, 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 59B detects and outputs the 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 printing tool of the stamper is not at the home position, so the pulse motor 52
0 starts normal rotation bias and starts counting the amount of rotation (9
6), and the state of sensor 536 11! , the reading and the amount of rotation are performed (97a, 98), and when the sensor 536 becomes light-shielded, the printing tool has reached the home position, so the motor 520 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 a light shielding state, it is abnormal, so stop the motor 520 (99) and send a mechanism abnormality to 22-1-10 (100) until the power is cut off. stand by(
1”OL).

Now, if the sensor 536 is shielded from light, then the state of the sensor 547 is referred to (102). When the sensor 547 detects light (reflector 545), the second printing cylinder 541 (publisher printing surface) is at the home 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
advance the latch claw at the tip of the latch to the base of the latch wing 543, then rotate the pulse motor 520 in the reverse direction by a predetermined angle, then cut off the energization of the solenoid 555, and then rotate the pulse motor 520 forward by the predetermined angle. Energize and power the motor 520
A stop restraining current of 31f1 is applied. As a result, the second printing shoulder 541 is rotated by 360a15=72°, and its printing surface is advanced by one step. Sensor 536 has returned to its light-blocking state.

When this 1-step printing surface feed is completed, the feed step counter is incremented by 1 count and the count value (feed step amount) is compared with 4 (104). If it is not -4, the sensor 547 is checked again. Referring to the state, if it is light-blocked, 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 printing position 541 is set to the home position (first printing source is printing position r11).

Note that if the sensor 547 does not become light-shielded even after four step feeds, it is determined that there is a mechanical abnormality and a mechanical abnormality is sent to the unit 10 (100) and the process proceeds to abnormality standby (101).

When the second printing cylinder 541 is at the home position, the home position of the first printing cylinder 540 (drawing type and side) 540 is next determined, and if there is no home position setting, the home position setting of the second printing cylinder 541 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 a signal from the unit 10 (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 publisher section data for which the stamp was specified (the numbers of the first to fifth publisher stamps) is compared with the current position (the number of the first publisher section = 1), and (115 )
1. If the two do not match, the second printing cylinder 541 is driven in steps (116). The one-step drive 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, 2 steps are driven, and 3 is stored 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, driving in 3 steps. Next, compare the drawing egg data (1st to 5th drawing seed mark numbers) and the current position (1st drawing egg number = 1) (115
), if they 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 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 IO, 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 0, the pulse motor 520 is activated by the encoder 730.
The motor is energized to rotate in the forward direction in synchronization with the pulse of , and starts counting the number of rotations of the motor (127 times).

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), 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 is applied to the motor 520 (131). In addition.

When a stamp is not specified, the motor 520 is not energized and the solenoid 578 is energized after the sensor 598 detects paper. Since the solenoid 578 is energized, the roller 572 contacts the free rotation wheels 514 and 532, and since the roller 572 is rotating (it has been rotating with the roller 582 since the start), the incoming paper is 572 and free rotating wheels 514, 532, the paper is sent to delivery rollers 580, 582, and delivered 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 . The printing position in the direction perpendicular to the paper feeding direction is determined by the position of the base frame 502 in the perpendicular 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 cylinders 540, 541, which are connected to solenoids 554+5
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 cylinders 540 and 541 are polygonal and are installed eccentrically from the printing co-rotating shafts 510 and 528, the printing cylinders 540 and 541 are set at the printing position during the rotation of the printing tool (one rotation of 510). Only the printed side is stamped. There are no stains on the paper. In addition, the printing rubber supporting side of the printing bend 540° 541 is as follows:
It does not have to be a flat surface, but may be an arcuate curved surface.

(4) The stamp roller 572 can move forward and backward and is driven by a solenoid 578, and in the forward position the paper is pushed up slightly from the conveying surface toward the free rotation wheel, and in 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 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 manual rotation wheel 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.

(io) 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 I structure unit, and
All you have to do is stop the protection in the event of a jam or abnormality and send the data to the main control unit. The movement of the entire sheet processing machine 900 and the movement of the mechanical units are matched, so that a response to a trouble is quick, and moreover, the severity of the trouble is prevented.

(11) If the signals and data obtained from the setting state of the host such as the copying machine 800 overlap with the signals and data obtained from the setting state 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 the σ8 start of processing should be 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 1- 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.
