Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an automatic punching device that automatically punches file holes in a sheet of paper or the like.

・2) Prior art This type of device includes (1) a conventional device that punches file holes by energizing a punch unit while feeding the paper; (2)
(3) A register is placed in the direction in which the paper travels, the paper is stopped by the register, and a file hole is punched. There are 2 types that have two sides secured with registers and a file hole punched.

However, in the method (1) above, the punch holes are misaligned in the direction in which the paper travels and in the direction perpendicular thereto, resulting in large variations in the position of the punch holes, and the punch holes may be deformed or torn. These problems especially occur when paper is fed at high speed. In the case of (2), the punch holes tend to be misaligned in the direction perpendicular to the direction in which the paper travels, and the punch hole positions vary widely. In addition, in the case of (3), after the paper is stopped by placing two sides against the two registers, the paper moves back and forwards a little due to straining and bending of the paper until the punch hole is punched. causing misalignment.

Particularly when punching a hole in one edge of a sheet of paper that has been subjected to a folding process such as quarter-folding, half-folding, or JIS folding, simply stopping the paper with two registers tends to cause the punching hole to shift.

■Purpose The first object of the present invention is to provide an automatic punching device with small punch hole misalignment, and the second purpose of the present invention is to provide an automatic punch device with no punch hole misalignment even in folded sheets. shall be.

■Structure and ■Effects In order to achieve the above object, in the present invention, a first register is disposed in the paper feeding direction between the paper input conveying path and the paper sending path; A movable register is arranged perpendicular to the direction; a solenoid is coupled to the movable resistor to drive the movable register to a paper stop position and a retreat position; A punch unit is arranged between the paper input conveyance path and the movable register; A direction for directing one sheet to the paper output path and the first register are provided between the punch data l- and the movable register. The second motor is driven in the direction of
a control means for energizing the punch unit with the movable register at the paper stop position and the second feeding means in the paper feeding driving state;

According to this, the first feeding means feeds the sheet toward the movable register, the second feeding means feeds the sheet toward the first register and the movable register, and aligns two sides of the sheet with the respective registers, Moreover, even during punching, the feed drive is continued to prevent paper from returning due to strain or bending, while punching holes in the sheet. Therefore, punch hole misalignment is reduced, and punch hole misalignment is also reduced in folded sheets, and in particular, punch hole misalignment between the upper and lower sides of the folded sheet is eliminated.

In a preferred embodiment of the invention, the second feeding means comprises:
! f, wL At least two rollers placed apart in a direction intersecting the paper feeding direction from the feeding path to the paper feeding path, and a sphere riding on them, with a diameter larger than the diameter of the roller near the first register. The diameter of the rollers is also larger than that of the first register, and the sheet is simultaneously fed in the direction of the first register and in the direction of the movable register. When the edge of the sheet hits the register, the sphere comes to a standstill and the rollers idle, but since a feeding force is applied to the paper, no paper slippage occurs.

In other embodiments of the present invention, the rollers have the same diameter and a common rotation axis, and the rotation axis is tilted slightly in the sheet feeding direction from a line orthogonal to the first register to move the sheet in the first register direction. and the direction of the movable register at the same time.

In a preferred embodiment of the invention, the first feeding means also comprises:
At least two rollers with a common axis and a sphere placed on them are arranged apart from each other in a direction intersecting the paper feeding direction from the paper input conveyance path to the paper output path, and the axis is connected to the first register. The sheet is placed at an angle smaller than 90 degrees with respect to the punch unit 11 from the upstream side of the punch unit. /Set in the register direction and the movable register direction simultaneously to ensure accurate alignment.

In a preferred embodiment of the present invention, the punch data j. is further provided with a punch solenoid for driving the punch base, the punch seat plate, and the punch scraper, and a support body supporting the punch solenoid and the punch seat plate is moved in the sheet feeding direction. a punch unit drive means that drives in a direction perpendicular to the
The punch unit is configured to move according to the sheet size. In addition, there are a plurality of movable registers, and there are four movable registers, one of which is selected according to the sheet size and driven to the paper stop position. According to this, accurate punch holes are formed in sheets of various sizes at positions corresponding to the sizes.

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

Next, referring to FIG. 5, the punch mechanism unit-IQ
Explain the formation of O:17).

'-' The slave groove unit 400 includes rollers 410, 412, 414, 104, 408, which receive the paper sent out from the unit 300, and rollers 410, 412, 414 whose roller axes are slightly inclined from the roller axes 402, 406. Fixed register 460 for alignment. Punch solenoid 438° punch 1/1
42. Delivery roller 416. /184°420 etc.

Shifting rollers 410, 412. and 414, the roller axis is slightly inclined toward the feeding roller 420 side from a line perpendicular to the fixed register 460, and the electric current sent by the rollers 404 and /108 not only has a feeding force in the direction of the roller 420, but also has a fixed register. A force of 4"r is applied to the paper 460. As a result, the paper is brought to the fixed register 460 before reaching the punch unit 7+- (438).

The diameter of roller 484 is the same as the diameter of rollers 414 and 420 and feeds at the same speed as them, while the diameter of roller 416 is slightly smaller than the diameter of roller 184 and feeds the paper at a slightly slower speed. As a result, the rollers 416 and 4811 not only apply a feeding force to the paper toward the movable register 1122 or 426, but also apply a force toward the fixed register 460.

In addition, instead of the configuration in which the roller diameters are different to apply a gathering force to the paper, the roller diameters may be made the same and the roller axes are tilted, or conversely, instead of having the roller shafts tilted, , the roller diameter may be different.

Punch solenoid 438 is fixed to support plate 436. One end of a punch arm 440 is coupled to the plunger of the solenoid 438 . Arm 440 is pin 4

An interlocking arm 434 is continuous to the support plate 436, and a punch seat plate 432 is fixed to the lower end of this interlocking arm 43.1, and a punch receiver 6444 is formed in this punch seat plate 432. With the punch seat plate 432 positioned below the paper conveyance surface and the punch base 442 positioned above the paper trl conveyance surface, the punch device can reciprocate in a direction perpendicular to the longitudinal direction of the register 460.

A threaded rod 448 is screwed into the support plate 436.
<z 44 a is rotationally driven by a pulse motor 450. When the bunch rod 442 is at the A4 punching position (the distance between the middle of the two punch marks 442 and the fixed register 460 is one-half of the long side of the A4 paper), the gap of the support plate 136 is
~A limit 1 switch 484 is fixed at the position where the Leica hits. 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 is 9 based on the fixed register 460 (between the two punch counters 442 and the fixed register 4).
The pulse motor 450 is energized to rotate in the normal direction for a time when the distance 21 between the A4 punch position and the A4 punch position is equal to the distance between the A4 punch position and the distance 21 between the B5 long side and the A4 punch position, and the pulse motor 450 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 1128 and 4211 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. Other major things about Laura include! A lv ball is placed on it.

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. Support 4S of this cutter 452
The structure and drive system are the same as those of the cutter 223 shown in FIG. 6a, so a description thereof will be omitted. Switch 47G (
1) is instantaneously closed, the cutter 452 moves back and forth once to cut the jammed paper. Punch mechanism Unisol l~400

7a to 7d show the control operation of the microprocessor I4 of the operation board control unit 10. The control operation of the operation board control unit 1Q, that is, the control operation of the microprocessor 4 will be described with reference to these drawings.

Referring first to FIG. 7a. When the power is turned on, the microprocessor (hereinafter simply referred to as the CPU) 1/1 initializes the input/output ports, registers for temporary data storage, status registers (flags), counters (program counters), and timers (Programmer 11). Clear timer) −°γ (step 1). In the following, the word "step" will be omitted in parentheses, and t! Display only the step symbol at t.

After completing the initialization, the CPU 14 reads the status. In this 7, first check whether there is a read flag (
2). At this point, we have just finished initializing, so
Since there is no read flag, the process advances to step 3 and the data is written to the operation board register. The standard data is: Paper size: Δ4 Fold selection: Unfolded / Horizontal orientation: Horizontal Stamp position: Omm Publisher: 1st design (1st publisher stamp) 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 operation board 12, standby (this is set at initialization),
All, unfolded l bE 0mmg without punch, 1st
Indicator lights indicating each of the design, tray, and tentative drawings are lit.

In Figure 6b, 3 assigned to the operating board register OBR
Indicates the write position of data to be temporarily written to the byte memory area (an area of the internal RAM of the CPU 111).

When the target data is written to the operation board register ○BP, the read flag is set (4). Next, copy [i 80
Referring to the state of the port that receives the input signal from the copying machine 800, it is determined whether the signal is being transmitted from the copying machine 800 (5
). When there is a transmission, it receives it and reads the signal and data,
It is determined whether the signal is a start signal or not (6). Start (If it is not No. 5, it is necessary to judge whether it is an end signal or not 7)
, if it is not the end number, it is data, so among the input data, data to which a memory bit is assigned to the operation board register ○BR is updated to the operation board register ○BR. When such an update is carried out, 1 is written to the bit indicated as copying machine input pin h in the operation board register ○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, CP
U14 stores in memory data received from the copying machine and indicating what has been written to the operation board register OBR (indicating what the written data is). 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 copy machine input bit.

If it is not 1 (data has not yet been received from the copier) (11), the contents of the operation register are updated according to the key-in, and the indicator light of 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 B3 next to A4 at the moment it becomes quiet, the indicator light for A4 is turned off, and the indicator light for B3 is turned on. do. When the key switch 12a is closed once when the size specification focus of the operation board register OBR is set to B5, the size specification focus is updated to data indicating A2, the indicator light of B5 is turned off, and the indicator light of A2 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 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,
Sea 1 ~ Star 1 for the processing machine mechanism to start operating
A signal is also received from the copying machine 800 and is also received from the Kurosaku board 12.
Star 1 - Key switch 12i is used to enter the key, but when even a portion of the data is being received from the copying machine 800 (OBR central copying machine input bit = 1), the switch 12i must be closed. The key-in of the start signal is not acknowledged in step 38. In this way, processing mechanism star 1- also gives priority 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 set the data in step 13 (set the key-in data), or the data is not sent from the copying machine (5 )L or there is no key-in (9), the process proceeds to step 14 in FIG. I3
．． 2 papers are not accepted).

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. Compare the data in board register ○BR and the data in previous operation board register POBR (
25). Note that the previous operation board register OBR was cleared during initialization in step ], so step 2 is the first time.
When proceeding to step 5, the contents of the two do not match. This is to keep in mind that the processing mode 1 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 Δ 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 27), first, the size is determined from the data at size designation pins 1 to 1 of the operation board register OBR (271).
.

If the size is A2, the primary refers to the OBR digit selection bit (272 to 27G).If the size is A2, the 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 two, data indicating the A2/longitudinal/passing mode is transmitted to unit I 20 (277). If 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, the OBR length/width specification bit t!
:Reference and if it indicates vertical (280), send A3/vertical/passing mode to unit 20 (281)
). If it indicates lateral, refer to the digit selection bit of OBR (282), and if it is unfolded, transmit A3/lateral/passing mode to unit 2o (283).

If it is in some possession, it will send the A3 90'' turn mode to the unit 20.

When the size is A4 (285>, see m/width specification hint 286), if it indicates the width (285>, see m/width specification hint 286)
86), transmits the A4/horizontal/passing mode to unit 2o (287). Unit 288 if it does not indicate the side
Then, the A4/90' turn mode is 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 85, it becomes the content of step 28.

With the above, when unit 20 is ready, unit IO
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 focus of the operation board register OBR is referred to (291, 292, 294). 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 JTS fold, the data of the size designation pin 1- and the data of the digit selection bit of the operation board register OBR are transmitted to the unit 30 (293, 296). With the above, unin 1~1° to 3
0 is given a control operating mode indication and will be set in the microprocessor of unit 30.

After completing the blade folding mode setting (29), the CPU 14 of the unit 10 sets the punching mode (3Q).

In this case, the operation board register ○BR.

Referring to the data for size upper chamber pit 1, digit selection focus data, and data for punch selection pit 1~ (301~
306, 308, 309), and when the final size is A4 and punched, the A4/punch mode is sent to the unit 40 (307).

If the final size is B5 and has a punch, Unino 1
-40 to send B5/punch mode 3 ] 0)
, otherwise sends a non-punch mode to unit 40.

After completing the punch mode setting (30), units 1 to 10
The CPU 14 sets the stamp mode (31).

In this case, the stamp selection bit of the operation board register ○BR is referred to (312), and if it is 1 indicating a stamp, the stamp selection bit, stamp position bit, and issuer selection bit of OBR are sent to the unit 5o. 1
~ and the data of the drawing row selection bit are transmitted (313
). If the stamp selection bit is O, a non-stamp signal is sent to unit 5o.

After completing the stamp mode setting (31), the unit io
The CPU'l sets the exclusive mode (32).

In this case, refer to the paper ejection selection bit of the operation board register OBR (321); if it is 1, it instructs the unit 60 to eject paper to the sorter (323); if it is 0, it instructs the unit 60 to eject paper to the sorter (323); if it is 0, it instructs 1 to eject the paper to (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 ○ by the execution of the preceding 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 copying machine 800 (6), refer to the ready/standby bit of the operation board register ○BR (35). If it is 1, it is a normal operation layer, so the units 20 to 60 are sent to the unit 20 to 60 at a predetermined timing. The start signals are sequentially transmitted (37).

Then, proceed to step 11g M removal again. When each of the units 20 to 60 receives the STAR 1 signal, it starts driving the I-co feed roller and waits for paper to arrive at each sensor. When paper arrives, predetermined control operations are initiated.

Control wholesale unit 10 gives units 20 to 60 stars 1~
Before or after applying the signal, the unit (-2
If 0 is in standby (unable to process) or becomes standby, unit IO C1) [14 is step 1 in Fig. 7b.
4, read this and proceed to the abnormality processing of the unit 20 (15). In this abnormality processing, first, the copier user 1- in the operation board register OBR is referred to (151). If it is 1, data is received from Copy Ja800,
Since the sheet processing has already started before or has already started, an abnormality (standby) is sent to the copying machine 800 (152).

Then, the ready/standby bit of OBR indicates that the operation is not possible.
and turn off the ready indicator light on the operation board 12.
The standby indicator light is turned on (153). Next unit 154
In order to receive more abnormal data (154), if the abnormal data indicates a paper jam, the indicator light on the abnormal display panel 13 corresponding to the position data is turned on (156).
. When the abnormal data indicates that the paper jam is not a paper jam, all indicator lights associated with the abnormal VQ structure unit on the display panel 13 are turned on (157). Then, the process returns to the state reading after step 5 in FIG. 7a.

n-side control unit 10 If the unit 30 is in standby (unable to process) or becomes standby before or after giving the start signal to the unit 1-20 to 60, the CPU 14 of the unit 10 Step 16 in the diagram
Read this and set the unit 30's abnormal '7H<, processing (I7
). This abnormality processing (17) is the above-mentioned abnormality processing (]
This is the same as 5).

(For now, the unit 20 in (15) will be read as UNINO 1-30.

Before or after the control unit 10 gives the star 1 signal to the units 20 to 60, the unit 40 waits for 4 seconds.
! 1 (unable to process) or when the unit 10 is on standby, the C:PU 14 of the unit 10 performs step 7b of FIG. 8
Read this and proceed to abnormality processing of the unit 40 (19). This abnormality processing (19) is similar to the above-mentioned abnormality processing (15).

(a) Unit 20 in (15) is replaced with unit 40.

The control unit 10 connects the units 20 to 60 with stars 1, ,
If the unit 50 is in standby (unable to process) or becomes standby before giving the ja number or after being suspicious, the CPU 14 of the unit 10 reads this in step 20 of FIG. Proceed to abnormality processing (31).

This abnormality processing (21) is similar to the above-mentioned abnormality processing (15).

However, (15) should be read as ``uniso'' - 20 ``uniso h 50''.

Before or after the control unit 10 gives the star 1 signal to the units 20 to 60, if the unit 60 is on standby (unable to process) or becomes on standby, the CPU]4 of the unit 10 is set as shown in FIG. 7b. This is read in step 22 and the process proceeds to abnormality processing (23) of the unit 60. This abnormality processing (23) is similar to the above-mentioned abnormality processing (15).

For now, Unino 1-20 in (15) should be read as Uniso 1-60.

Next, the 1;11 control operation of the microprocessor of the punch control unit 40 will be described with reference to FIGS. 8a and 8b. See also Figure 5.

Referring first to FIG. 8a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) of the unit 40
executes the initial (hi (40)) and takes the state f3 g (41)
Execute. Note that during initialization, standby is set on the signal line to units 1-10.

As a result of the status reading (41), if the sensor 478 or 480 detects 2'5 (42), it means that there is a remaining paper, so a paper jam message should be sent to the unit 10 (43).
Read the state of switch 476 (FIG. 1). While there is a paper jam, steps 44-41-42-43-44-
41-... and so on. When the switch 476 becomes idle, it reads whether the switch 460 is open or closed, and if it is open, the cutter 452 is not at the home position shown in FIG. 5, so it waits. When the switch 476 is turned off while the cutter 452 is at the home position,
Proceeding to steps 44-45-46, the pulse motor 45
8 is energized for normal rotation, and the timer Tam is set to 1 (46 seconds).Tam is the time required for the cutter 1152 to advance a distance slightly longer than the length of the short side of A2.
7) Then, stop the motor 458 48), motor 45
8 is reversely energized and timer Tam is set to 1- (5o)
. Then, wait until the switch 460 is closed or the timer Tam times out (51, 52), and when the switch 460 is closed, the cutter 452 has returned to the ho 11 position, so the motor 1158 is stopped (56).
. If the timer "Jam" expires without the switch 460 being closed, the return of the cutter 452 is abnormal, so the energization of the motor 458 should be stopped (53), and the unit 1
Low purchase difference to 09. 54) Difference; (゛Waiting process (
Proceed to step 55). The CPU of the unit 40 remains in this abnormal standby state until the power is turned on again.

Now, if the switch 460 is closed and the monitor 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 A4 when the bunch unit is from the 85 punch position.
This is the time required to reach the punch position (home position).

When switch 484 is closed (59), motor 45
0 is stopped (62). 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. Status reading 41.

Neither sensor 478 nor 480 detects paper (42)
, when the switch 460 is closed (49) and the switch 484 is closed (57), it is in a normal standby state, so a ready message is sent to the unit 10 (63).

After transmitting ready to unit 10 (63), it waits for transmission from unit 10 (64). When there is a transmission, it is received (65). This feed (i) is the punch mode setting (30) in FIG. 7d.

Upon receiving a signal from unit 10 (65).

Proceeding to step 66 of FIG. 8b, the signal is STAR 1~(
Check whether it is No. A or not. If it is not a star 1 signal, it is checked whether it is data (67), and if it is data, it stores the received data in the mode register (68) and refers to the contents of the data in the mode register (69.70). If the content is punch specification and B version, the pulse motor 1150 is moved from the A4 punch position (Ho 11 position shown in Fig. 5) to the B5 punch position.
The punch position is rotated forward and stopped at the BS punch position (71). When it stops, it notifies the unit 10 that it is ready again (63). If there is no punch instruction or if it is an A-version punch, the unit 10 is immediately notified of ready (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.

this! When tracing the construction process, the unit 400 is in the ready state, so immediately after that, in step 63, the unit 400 is in the ready state.
-10, and waits for the start signal to arrive from unit 10 again.

Now, when the star 1 signal arrives and the sensor 478 detects paper before the timer Ts times out (73), the mode 1 signal arrives.
- Refer to the contents of the register (77, 78), and when punching is specified and it is the A version, the solenoid 428 is energized and the register 426 is raised to the paper stop position (79). When a punch is instructed and it is the B version, the solenoid 424 is energized and the register 422 is raised to the J' stop position (80).
. When no punch is instructed, solenoid 428,
424 is not energized.

Now, when the solenoid 426 or 424 is energized, it waits until the sensor 480 detects electricity (81), and when it detects paper, it energizes the copper ball solenoids 418 and 482 and
19,483 and starts pulse counting to determine the timing at which the abrasive comes into contact with the movable register (83.84).

When the paper comes into contact with the register 426 or 422 (85), the ff1m ball solenoid 418 is activated.

482 is de-energized and the f1 balls 419, 483 are dropped (86), whereby the paper is placed in the register 422 or 42.

8, and cut a hole in the paper (87). Next, turn off the current to the solenoids 428, 42/I (88), refer to the detection status of the sensor 480 (89), and when the sensor 480 changes from detecting the nail to non-detecting (when the punch passes through the sensor 480), the timer Ts is activated. 72), wait for the arrival of the next fire (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.

In this way, one sheet of paper registers 460 and 422 (or 4
26) Since the punch hole is punched while being driven and stopped, the punch hole is accurate and the punch hole does not become deformed or torn.
