Therefore, there is no need to perform stabilization work again later, improving the efficiency of office work.

〔Example] The details of the present invention will be explained based on embodiments shown in the drawings.

The apparatus to which the present invention is applied includes, for example, as shown in FIG. 1, a sorter 3 attached to a copying machine main body l equipped with an automatic document feeder (ADF).

When you set the original in the order of pages face down on the center table 4 of the automatic document feeder (ADF), set the required number of copies, and press the print button, the first page of the original is placed on the contact glass 5. position, an image is formed on the photoreceptor 7 by reading by the optical system 6, the image is transferred to copy paper fed by the paper feeder 8, and the image is reversed in the conveyance path 9 and sent to the sorter with the image side facing downward. The liquid is sequentially discharged into each of the three bins 10 from the top. The same process is then repeated for the second original and subsequent originals.

When all copies of the manuscript are completed, the copies are stored in the bins as many as the initially set number of copies, arranged in page order. In other words, collation is completed.

The sorter 3 is provided with a stable device 11, as shown in FIG. 2, for example. The stable device 11 is for each bin 1
It has a stapler 13 set on a table 12 that moves up and down so that it can be stopped at the zero position. The stand 12 is moved up and down by a drive screw shaft 14, for example.

Each bin IO has copy paper 16 fed by a feeding roller 15.
It can be formed as a tray to carry the. The tray 10 has a stomper 1 provided on the end face on the stapler 13 side.
7, and a presser 18 which presses the copy paper 16 on the striker 17 and acts to align it.

The tray 10 is configured to be movable so as to feed the copy paper to the holder 19 of the stapler 13 with the copy paper 16 placed thereon, and is normally held at a standby position by a spring 20.

As shown in FIGS. 2 and 3, the stapling device 11 includes a stapler 13 and a pedestal 19 for the stapler 13.
In order to place the copy paper 16 in a predetermined position, the tray 10
and a tensioning device 21 for pulling the. Tension device 2
1 is placed on a stand 12 and moves up and down together with the stapler 13. The tensioning device 21 has a solenoid 22 and a hook 24 fixed to a plunger 23 of the solenoid 22.

The hook 24 is formed to engage with a bin 25 fixed to the tray 10.

When the solenoid 22 is energized, the hook 24 is retracted, the biasing bin 25 is pulled, and the tray 10 is pulled toward the stapler 13 against the force of the spring 20. At this time, the spaced portion of the copy paper 16 is placed on the pedestal 19 of the stapler 13.

The pedestal 19 has a stapler paper detection sensor (S13) 20.
is provided to detect the presence or absence of paper on the pedestal 19.

When the solenoid 22 is deenergized, the force of the spring causes the tray 1 to
0 is retracted and the copy t(E16 is released from the stapler 13).

The stapler 13 is formed so that a staple cartridge 27 containing a large number of staples 26 can be attached to and detached from the stapler 13.

The needles in the needle cartridge nozzle 27 are advanced by a feed heald 29 driven by a drive motor 28.

The arm 30 is moved up and down by 1g by the drive motor 28, thereby the head 31 is moved up and down, and the needle 26 is struck against the pedestal 19. The needle binds the copy paper 16 like a staple.

A needle end sensor (312) 32 is provided at a predetermined number of needle positions from the driving position by the head 31, and detects the presence or absence of a needle. The predetermined number takes into consideration the bin coefficient, for example 20, and the number of compaction positions of one document, for example 2 at most, and in this case, a number greater than 40, for example 70 to 1.
00 stitches.

Stapler 13 first staples the copy sheets in the top bin,
The table 12 is lowered by one bin, the tray 10 is pulled by the operation of the solenoid 22, stapled by the stapler 13, the solenoid is deenergized, the tray 10 is returned, and the operation of lowering to the next bin is repeated. A sensor, a drive control device for a drive shaft, etc. necessary for stopping the stand 12 at a predetermined position for each bin are provided.

As shown in FIG. 4, the stapler 13 is arranged to staple the copy sheets on the bin 10 at a predetermined position in one corner with a staple 26. Moreover, if the first binding position is when the needle 26 for compacting extends horizontally to a vertically long copy sheet as shown in FIG. 4, then the first binding position (horizontal position) A second binding position (diagonal position) B where the needles are tilted approximately 45 degrees to A, and a third binding position (diagonal position) where the needles are tilted 90 degrees to the first sip position and extend vertically.
It can be made switchable between the close position (vertical position) and the close position (vertical position). In this case, the stapler 13 is pivoted around the central axis 33 and its angular position can be changed to 45 degrees.

The switching positions are not limited to these three positions, but may be made to be switchable to any angular position.

In order to adjust the direction of the stapler 13, as shown in FIGS. 6 and 7, it is rotatably supported via a bearing 35 on a table 12 which can be moved up and down by a drive screw shaft 14 and a guide shaft 34. An auxiliary stand 36 is fixed to the central shaft 33, and a stapler 13 is fixed to this auxiliary stand 36.

A gear 37 is fixed to the central shaft 33, and this gear 37 is connected to a motor (M3) supported by a bracket 3 on the stand 12.
It meshes with a drive gear 40 attached to 39 and is rotated.

Mount 2 has a sensor at a predetermined switching position, for example, the first
Horizontal position sensor (S4) 41 for the binding position (horizontal) and diagonal position sensor (36) 4 for the 21st J binding position (diagonal)
2 and a vertical position sensor (S5) for the third binding position (vertical)
43 is provided to detect that the stapler 13 has come to a predetermined position, stop the motor (M3) 39, and control the direction of the stapler 13.

The direction control of the stapler 13 can be configured to be manually controlled as shown in FIGS. 8 and 9, in contrast to the automatic control shown in FIGS. 6 and 7. In this case, the seventh
The gear 37, motor 39 and drive gear 40 are removed from the example shown, and instead a thumbscrew 44 is rotatably or screwably attached to the auxiliary base 36, and this thumbscrew 44 is attached to a predetermined position on the base 12. The position is fixed by screwing it into the screw hole 45 at the position or pressing it against the stand 12, and when changing the direction, loosen the thumbscrew 44, move the auxiliary stand 36, and tighten the thumbscrew 44 to fix it at the desired position. In this example, the user can easily change the direction of the stapler 13. A lever can also be used instead of the thumbscrew 44. Any number of switching positions can also be selected.

As shown in FIG.
When the direction is taken as the direction, the position ff,! can be adjusted. For this reason, the 11th
As shown in the figure, an auxiliary stand 36 or an auxiliary bracket that makes the auxiliary stand rotatable is fixed to the stand 12 with a screw 46, and the screw 46 is inserted into a long hole 47 in the X direction of the auxiliary stand 36 or the auxiliary bracket. do. This allows the stapler to
13 can be easily adjusted by hand in the X direction. Further, the stapler 13 is fixed to the auxiliary stand 36 with screws 48, and the screws 48 are inserted into long holes in the X direction formed in the stapler 13.

By loosening and tightening the screw 48, the stapler 13
You can easily adjust the position manually. The screws 46, 48 can also be replaced with thumbscrews or levers for ease of operation.

If you want to adjust automatically, as shown in Figure 12,
The bracket 49 to which the stapler 13 is fixed is slidably guided in the X direction by a guide bar 52.
is instructed to be fixed to a support 51 fixed to the movable base 50, and is rotatably supported by the support 51 and rotated by a motor (M3) 53 by screwing the movable base 5o into the feed screw 54. can be automatically adjusted in the X direction.

Similarly, the movable base 50 is slidably guided in the X direction by a guide rod 55 fixed to the base 12, and when the movable base 50 engages with a feed screw 56 rotatably supported by the base 12, When the feed screw 56 is rotated by the motor (M5) 57, the multi-moving table 5° is moved in the X direction, and the stapler 13 is also moved in the X direction.

By controlling the rotation of the motor (M3) 53 and the motor (M5) 57, the position of the stapler 13 in the X direction and the X direction can be adjusted.

A position home sensor (37, S8) is provided to automatically control the X-direction and X-direction positions of the stapler I3. For example, as the position home sensor leaf (S7.3B),
As shown in FIGS. 13 and 14, a transmission type photointerrupter 58 and a shielding plate 59 are used. The position home sensors (37, 38) are arranged as shown in FIGS. 15 and 16, for example. In other words, a transmission type photo ink converter 58a forming a position home sensor (S8) for X direction control.
is fixed to the stand 12, and the shielding plate 59a is fixed to the movable stand 50. Further, a transmission type photo ink converter 58b forming a position home sensor (S7) for X-direction control is fixed to the movable table 507, and a shielding plate 59b is fixed to the bracket 1-49.

The shielding plate 59 moves relative to the transmission type photo ink converter 58, and the shield plate 59 moves relative to the transmission type photo ink converter 58.
When the shielding plate 59 is away from the transmissive photo ink converter 58, it is turned OFF. This position home sensor (37, S8) detects the X direction and the reference position of the stapler 13 in the X direction.

In the standard state of the copying machine, for example when the main switch is ON, the stapler 13 is moved by the motor (
M3) 53 and motor (λi5) 57 are controlled.

By pushing the position adjustment switch placed on the operating section, the motor (M3) 53 and motor (M5) 57 are driven, and the stapler 13 is moved by a specified distance in a specified direction. In this case, the moving distance is motor (M3) 5
3 and the rotation time or number of rotations of the motor (M5) 57.

As described above, the stapler 13 can perform position adjustment and direction adjustment in the X direction and the Y direction.

The operation panel provided on the copying machine main body 2 can be configured, for example, as shown in FIG. to check the mode.

The 10 key (numeric keypad) 101 is a key to set the number of copies, and the value is displayed in the cent number display section 102.
(The actual number of copies is displayed on the copy number display section 113.) The C/S key 103 is
- This is a key that returns the number of copies to 1, and also has the function of a copy interrupt key. The print key 104 is a copy start key, and is valid when the printable display is ON, and is invalid when the print prohibition display is ON.

Bin paper presence display 105 lights up when there is paper in the bin of the sorter when the stable mode (automatic) is selected (to be described later), and at the same time it becomes a display indicating that printing is not possible. Since there is a limit to the number of sheets (for example, in this embodiment, it is set to 30 sheets), if it is unclear how many sheets of paper are in the bin, stabilization is prohibited.

Well-known sort mode selection key 1 for sorter selection
06 and LED display are provided.

When stabilizing, a stable key 107 is provided for selecting a stable mode, and after copying is completed, the copied items in each bin of the sorter are automatically checked according to each stable condition on the right side of the operation panel. Stapling is performed using a stapler 13.

When the manual stable key 108 is turned on with the above-mentioned stable selected, it enables offline stabilization.

The two-stroke key 109 enables binding similar to bookbinding. In this case, the staple direction key 110
This is possible only for horizontal instructions. The staple direction key 110 is used to select the binding direction.
You can select vertical, horizontal, and diagonal directions for some corners of the paper.

The normal position is horizontal.

Staple position Correspondingly possible.

A schematic diagram of the control block of the copying machine is shown in No. 18 [ff1A].

The CPU 115 is a well-known microcomputer, and the R

One I10 element 120 is connected to a key switch on the operation panel and signal lines of an LED display, for example, a well-known key matrix 124 shown in FIG. 18B, and an LED matrix 125 shown in FIG. 18C. and performs input/output processing.

In this embodiment, those shown in FIGS. 19 and 20 are connected to the signal group A126 and the load group A127, respectively, and input/output processing is performed through 110121.122.

Signal group BI28 and load group B129 belong to the copying machine main body, and their explanation will be omitted.

The ADF control unit 123 is a well-known automatic document feeder (ADF).
), and only the portions of its control signals that require explanation in this embodiment are illustrated. In this embodiment, the CPU 11
5 and the ADF control unit 123 communicate using a serial communication method.

For example, each section shown in FIG. 19 is connected to the signal group A126.

S 1-314 are all photosensors (LEDs and phototransistors) and perform various detections inside the sorter.

S15 is an automatic staple selection switch, which can be set according to the user's request.If the stapler 13 is used to staple mostly sorted copy sheets, this automatic staple selection switch can be set at the user's request. SI5 to O
If set to N, press the sorter key and staple key 10.
Even if you forget to press 7, the staple mode is automatically set.

For example, the various parts shown in FIG. 20 are connected as the load group 127.

M1-M5 are DC motors, M1 controls rotation only in a certain direction, and M2 to M5 control forward and reverse rotation.

SQL1 is a solenoid.

Flowchart 1 for controlling the copy paper processing apparatus according to the present invention.
This is explained by:

In FIG. 21, when the power is turned on to the copying machine, S T
It becomes ART and executes the "input reading subroutine" which reads the data of various signal groups.

Based on the data, load group B129 of the copying machine main body is activated and initialized. It also initializes the display etc.

Next, the subroutine FSUB I OJ is executed to initialize the sorter and staple devices.

In the subroutine rsUB I OJ, as shown in FIG. 25, Nisub/I/-1-7rsUBo IJ-rsUB.

4J processing is performed to initialize each position of the stapler. In the subroutine rsUBO1,+, the 26th
As shown in the figure, the direction home sensor (also a horizontal position sensor) (S4) 41 for setting the staple direction is
Drive the three motors (M3) in the reverse direction until N. In the subroutine rsUB02J, as shown in FIG.
The staple position in the Y direction is returned to the home position, and the home position is determined by the position home sensor S8, that is, the configuration of the shielding plate 59a fixed to the movable table 50 and the transmissive photo ink converter 58a fixed to the table 12. It is a control that decides.

If the position home sensor S8 is ON, the motor (M
5) 57 turns forward ONL, and turns OFF position home sensor S8
F, then reverse the motor (M5) 57 again, and when the position home sensor S8 is ONL, turn the motor (M5) 57 OFF.
Press F to determine the home position.

Subroutine rsUBO3J performs processing to return the stable position in the X direction to the home position, and subroutine rsU
This is similar to the control of BO2J. In this case the motor (M4)
53 and a transmissive photo ink converter 58b forming a position home sensor S7. subroutine rsU
At BO4j, control is performed to determine the home position of the stapler 13 in the vertical direction. The motor M2 is rotated in reverse to position the motor M2 until the sensor S2 turns ON. Subroutine 1rsU
After BO4J counter (CNTM) and flag [FBP
Reset E) and finish.

Next, execute "input reading" again, check the key input of each stable mode on the operation panel, and set the mode and LED display.

When the stable key 107 is turned on, the stable mode is selected and the stable LED is turned on.

At this time, the sort mode is automatically selected and the sort LED is also turned on. Also, the stack LED is turned off.

Next, when the two-stroke mode is selected by the two-stroke key 109, the two-stroke LED is turned ONL, and at the same time, the stable direction is automatically selected to be horizontal.

In the case of two-stroke mode, vertical and diagonal strikes are structurally impossible to stabilize, so horizontal strikes are automatically performed.

If it is not a two-stroke, check whether the stable direction is vertical or diagonal, and if vertical is selected, turn on the vertical LED.
If it is diagonal, turn on the diagonal LED. If neither is selected, turn on the horizontal LED and set the horizontal direction mode. That is, the stable direction when the stable mode is selected is preferentially selected as the horizontal direction.

Next, stable position, X key 1'l I, X key 112
In this example, the stable position is the first
As shown in Figure 0, the normal position of both X and Y is 6M from the edge of the paper. Settings are made using the X key 111 and the X key 112. X key 11
If 1 is not turned on, the normal LED indicating the normal position is turned on, and when the X key 111 is turned on once, +211 is first turned on.
Turn on the n LED and turn off the normal LED.

When turned on twice, the +2 body LED is turned off and the +4 mm LED is turned on. 12mm in the third time,
On the 4th time, switch the 4W LED in the same way and turn it on 5 times.
Then, the normal LED turns ON and returns to normal.

Next, regarding the X key 112, similarly to the X key 111,
Selectively lights the mode center and LED.

Next, perform the stapler-less check with the staple end sensor (S).
12) Perform step 32. If there is a needle, move to the next step. If there is no needle, turn the needleless display ONL and set the copy prohibition flag to O.
Do N.

Next, recheck the sorting turbine paper. If there is no paper, the bottle paper display LED is set to OFF, and the copy prohibition flag is also set to OFF. If there is paper, turn on the copy prohibition flag.

If the manual stable key 108 is not turned on, the bin paper present LED is turned on.

If there is paper and the manual stable key 108 is turned on, the copy enable flag is turned on and the stable operation subroutine rSTPL2 is executed.

Here, if there is no paper in the sorter bin, stabilization operations can be prohibited without the manual stabilization key, and stabilization errors can be prevented when there is no paper in the stable.

Furthermore, since auto-stable copying is prohibited when the paper is skewed, it is possible to prevent the mistake of slurping the previous copy paper together or the stability mistake due to excess paper.

Furthermore, offline stabilization is possible by activating the manual stabilization key when paper is present (for example, stabilization is enabled by setting paper other than copy paper in the sorter bin).

In the subroutine r S T P L 2 J, the 31st
As shown in the figure, first the manual staple counter C
If the data is 0, the positioning operation 1 subroutine rPST1 is executed; if the data is not 0, the positioning operation is not performed. This counter (CNTM) is normally O, but as will be explained in detail later, manual stapling can be performed for both one stable stapling and continuous stapling. This is to avoid positioning movement 1.

The subroutine rPSTIJ for positioning operation 1 is as shown in FIG.
Execute. In rsUBloJ, as already explained, the operation of returning the stapler unit to the home position is performed.

Next, execute subroutine rsUB100.6 Subroutine l'5tJB100. In +, as shown in FIG. 34, vertical, diagonal, and horizontal position control is performed, which is selected in the stapling direction mode setting described above.

If the staple direction is vertical, the vertical position sensor (35
)43, and if it is not turned on, the motor (M3
) 39 is turned on for forward rotation, and if the vertical position set (S5) 43 is turned on, -[--ta (M5) 39 is turned off.

Similarly, if it is horizontal, the horizontal position sensor (34) 41 is turned on.
Rotate the motor (M3) 39 in the reverse direction until the When the diagonal position sensor (S6) 42 is not ON, if the horizontal position sensor (S4) 41 is ON, the motor (M3)
) 39 in the normal direction, the diagonal position sensor (S6) 42
If the horizontal position sensor (34) 41 is OFF, the motor (M3) 39 is rotated in the reverse direction to control the position so that the diagonal position sensor (S6) 42 turns ON.

Next, subroutine rsUB200a is executed.

In subroutine rsUB200J, position adjustment control in the Y direction is performed as shown in FIG.

First, check whether the set value is 2 mm, and if yes, set the timer Tl to 71=10.Oms. Or the setting value is 41! If I11, timer TI is TI=20
Set to 0ms. If the set value is neither 2nd order nor 4mm, this routine ends. After the timer cent, start the timer, then check whether it is in the + direction or one direction, and if it is in the ten direction, rotate the motor (M5) 57 in the normal direction.
Wait until the timer times up and motor (M5) 57
Turn off. Similarly, if it is one direction, the motor (M5)
Similarly, the motor (M5) 57 is turned off after waiting until the timer times up. -For example, a motor (
M5) Position control in the Y direction by driving 57? IU Lma2
This can be done at a speed of 0n+m/s.

When the subroutine rsUB200a ends, it is next checked whether or not it is the 2-wood hitting mode. If the mode is not 2-wood cutting mode, subroutine rsUB300J is executed.

Subroutine fsUB300J is subroutine fs[J
It is almost the same as B20QJ, and is position adjustment control in the X direction, and positioning is performed by controlling the motor (M4) 53.

In the case of the double-stapling mode, the motor (M4) 53 is turned on in normal rotation until the sensor S9 turns on the staple unit, and then the subroutine rsUB300 is similarly executed to end this subroutine rPsT1j.

In subroutine rsTPL2J, subroutine rP
When sTIJ is executed, subroutine rsUB40
Execute 0J. This subroutine moves the bin to the stapling position, performs the stapling operation, and returns the bin.

In FIG. 37, first, SQL 1 is turned on. By driving solenoid SQL 1, the bin is in a stable position! Move until. After turning on SQL 1, is there a tie? -Tl
Set TI to 200ms and start the timer TI.
When the time-up occurs, the stapler paper detection sensor S1
Check 3.

This stapler paper detection sensor is a sensor for checking the presence or absence of paper on the bin, and if the bin is empty when the bin is moved, this subroutine is terminated without performing the next stapling operation. This is so that during manual stapling, even if it is not known how many bins there are sheets, the stapling operation can be completed as soon as the paper on the bin is exhausted. Furthermore, even during auto stapling, if for some reason a sheet of paper is removed from an intermediate bin, the job can be moved to the next bin without the stabilization operation.

In Fig. 3, the stapler-paper detection sensor (Si2)
When 20 is OFF, the bin paper out flag (FBPE) is set and 5OLI is turned OFF.

If the stapler paper detection sensor (S13) 20 is ON, then the stapling motor (Ml) 28 is turned ON. When this motor is turned on, the staple drive unit operates to drive the staples into the paper. motor(
After Ml) 28 is turned on, the stapler drive home sensor Sll is turned off and the stapler drive home sensor Sll is turned on again.
Press J to turn off. Next, SOL1 is turned off and the timer T1 is operated until the bin returns to the predetermined position, and this subroutine fsUB400J is ended.

Subroutine rsUB400. When the + is completed, the contents of the manual staple counter (CNTM) are increased by +1.
Then move on.

Next, check whether the manual staple key is in the ONL position.

If ONL is left alone, the above-mentioned bottle paper empty flag (FBP
Check E), and if it is not °l, subroutine rs [
Run JB500J.

This content is such that if the manual staple key continues to be turned on after one staple operation is completed, the manual staple operation can be performed continuously. In other words, if the manual stapling key is turned on until the stapling operation for a desired bin is completed, the desired number of copies of the copied sheets can be stapled, and the remaining copies can be left without stapling. Subroutine rsUB500J
As shown in FIG. 38, this is a subroutine in which the motor M2 is rotated forward for 700 m5 to move to the next bin position. −
For example, when the distance between bins is 35+nm each, the stapler unit movement speed by motor M2 is 50mm/
It becomes s. Subrucia '5UB500J as above
After moving the unit to the next bin position (downward), execute subroutine FSUB40 again.
Returning to the routine for executing 0J, the stable operation and movement of the staple unit are repeated. Then the counter (C
NTM] continues the count amplifier, and if the manual staple key is OFF, moves to the next step.

Also, if the manual staple key remains ON, the flag (F
When BPE)=1, there is no paper on the bin, so the next step is complicated.

Next, check the two-shot mode. If it is not a double hit, the subroutine "5TPL2j ends. If it is a double hit, then the flag (FBPE) is checked. (
If FBPE)=1, the last bin in the double-thread one-sided mode was out of paper, so it is necessary to return the staple unit to the previous bin position (above), and the subroutine rsUB510J is executed here. subroutine rs
UB510" is the subroutine rs as shown in FIG.
This subroutine differs from UB500J only in the direction of rotation of the motor, and moves the stapler unit upward by one stage.

After executing the subroutine rsUB510J, the flag (FBP
E) is reset and the next step is f.

Also, before that (FBPEI check (FBP Sn) = 0
But let's move on to the next step.

Next, subroutine fPsT2J is executed.

The subroutine rPsT2J moves the stapler unit in the X direction, as shown in FIG.
M4) Drive 53 to the position where sensor S10 turns ON.

The sensor SIO is the other position reference when hitting two pieces of wood. After turning on sensor S10, subroutine fsUB300
At x, the position in the X direction is finely adjusted, and the subroutine "PsT2J" is ended.

Next, subroutine l'5UB400J is executed to perform stable operation. After stapling, the counter [CNTM
] is -1 and it is checked whether (CN TM ] is O. If it is not 0, there are remaining sheets, so subroutine rsUB510J is executed and the stapler unit is moved upward by one bin.

Thereafter, the subroutine rsUB400J is repeated and when the counter (CNTM) reaches 0, it means that all two strokes have been completed, and the subroutine fsTPL2J is ended.

In addition, in the case of double-stapling when the manual staple key 108 is not left ON, move the stable unit in the X direction from the middle of the bin as described above,
It is possible to continue stapling the other side of the main stapling to make any number of copies.

Also, the manual stable key 108 is ONL.

If it is not a stapler and a double stapler, then this subroutine l' S T P I-2J is finished, and then the stapler can be stapled. This is because the counter at the beginning of subroutine rsTPL2J [CNTM
] is not 0, initialization of the stapler, that is, subroutine rPsT1. This is to avoid doing ＋.

When the subroutine rsTPL2J ends, the main routine returns, and in FIG.
to set and process other copy modes. For example, the variable magnification mode is used to adjust the density, but there is no need to explain it in this embodiment, so it will be omitted.

In Figure 2, change the stable selection and i! The description has been made for the case where the staple is selected, but if the staple is not selected, the process jumps to A, and as shown in FIG. 22, since it is not a staple, the stable mode is canceled. That is, first, subroutine fsUB10j is executed to initialize each position of the stapler unit, and then all stapler-related LEDs are turned off.

After that, check the sorter key, turn on the sort mode LED if you want to sort, turn on the stack LE if you want to start, or turn on the stack LE.
D is set to ONL, if not selected, it is left as is, the bin paper presence display is set to OFF L, copying is not allowed at 7 lags is set to ○FFL, and the process moves on to reading the input of the above-mentioned step and other copy mode setting processing.

As described above, a decision is made as to what to do with the copied paper, and the processing is carried out, after which the copying routine is entered as shown in FIG.

First, check the copy prohibition flag.

If there is paper in the sorter in the staple mode, the copy prohibition flag is set, so a check is performed here, the print prohibition display is turned on, and the process returns to the previous step. B is the 21st
As shown in the figure, input reading is started again, and if there is paper in the sorting turbine in staple mode, it continues to be displayed, and copying is not possible until the paper is removed or the stable mode is released. Further, the copy prohibition flag is also turned ON under other conditions such as when the thermal fixing device does not reach a predetermined temperature during the input reading described above, but this will not be described in detail.

When the copy prohibition flag is cleared, the print permission display is turned to O.
Check the print key ON in NL. If the print key is not ONL, return to B.

When the print key 104 is turned on, the print ready display is turned off.
Press F to enter the copy routine.

First, the ONN of the document center sensor 320 is checked to see if a document is set in the ADF.

If it is OFF, normal pressure plate mode copying is performed since it has nothing to do with ADF.

If the document set sensor S20 is ON, the document feed is ON.
signal is sent to the ADF, waits until a document feed end signal is received from the ADF, and turns off the document feed signal when the document feed end signal is received from the ADF.

Next, the ON check of the ADF document set sensor S20 is performed again. Assuming that the document set sensor S20 is OFF here, it can be seen that the number of documents loaded into the ADF is one, so in the next check, if the staple mode is set, Cancels staple mode and sort mode, and if sort mode is set, cancels sort mode. This is because stapling and sawing 1- on a single original document is not very meaningful, and is more like a mode error such as copying in the mode set by the previous operator, so it is automatically canceled.

If the original set sensor 320 is ON, it is known that there are two or more originals, so the stapling and sorting checks described above are not performed.

Then check the sort mode again.

In sort mode, staple automatic selection switch S
15 is ON! , and if the staple automatic selection switch S15 is ON, such as when staples are often performed after sorting, and the number of copy cents (CNTST) is 2" or more, cancel the sort mode and staple. The LED is turned on, the staple horizontal direction LED is turned on, and the normal position LEDs of staple positions X and Y are turned on.

That is, the state is switched from the sort mode to the staple mode. This is a sort mode, and when there are two or more copies, they are often stapled after copying, so even if you forget to set the stapler, you can auto-staple. This mode is determined by the user's preference, so
A switch S]5 is provided so that the user can select the stable automatic mode.

After the document feeding of the ADF is completed and various automatic switching is completed, the document counter [CNTOLI is cleared once, ■ is cented, and then the process moves to the next step.

In FIG. 24, first the copy counter CCNTCP)
Clear.

Next, after executing a series of copy processes (not detailed) such as original exposure, development, paper feeding, transfer, separation, and cleaning, the copy counter (CNTCP) is incremented by 1, and then sorting or stapling is selected. And the paper is (
CNTCP) is discharged into the bin of the sorter with the number corresponding to it. When not sorting or stapling, the sheets are discharged into the same bin.

Next is the cent counter and copy counter (SNTST)
If ≠ [CNTCP], the copying process for that document has not finished, so the next copying process is executed and (S N
Repeat until T S T 'J = CCN T CP ]. When (SNTST) = (CNTCP), if the stack mode is selected, the copy paper ejection port for the next original is set in the bin of the sorter that is +1 to the contents of CCN T OL ].

Next, check the document set sensor S20 of the ADF, and if the document set sensor 320 is ON, the next document exists, so turn on document ejection and document feed, and finish ejecting and feeding the document. Wait until then, then eject and feed the document. Next, the original counter (CNTOLI) is incremented by 1, and as a result, if the original counter (CNTOLI) is not ≧31, the process returns to the copy routine again and repeats this process.

After repeating the above, when cNTOIi≧31, if the staple mode is selected, the stable mode is canceled and all staple-related LEDs are turned off.

Then select the sort mode and sort) L E D O
Do N.

This is because in the case of stapling, there is a limit to the stapling capacity, and in this embodiment, the limit is set at 30 sheets, so when 30 sheets are exceeded, the mode is automatically shifted to the sort mode.

After repeating copying and document exchange as described above, if the ADF document center sensor turns OFF, there is no next document, so the copy post-processing routine is executed.

The copy post-processing routine turns off the copying machine drive motor, and will not be described in detail.

Thereafter, it is checked whether the stapling mode is set, and if not, the process returns to the previous step and enters a standby state in which the next copy condition is accepted, etc.

If it is the stapling mode, the stapling operation subroutine rsTPL1j is executed from here.

Subroutine rsTPL1. +, as shown in FIG. 30, first the contents of the copy counter CCNTCPI are set in the staple counter (CNTSP). Next, the stapler initialization subroutine l'psT1
Execute j.

After that, the stapling operation subroutine is UB40Q.
Execute J.

Next, -l is obtained from the counter CCNTSPI and the counter (C
NTSP) = O. Since this counter matches the contents of the copy counter described above, it becomes O when stapling is performed for the number of copies. When it is not 0,
After executing the subroutine FSUB500 for moving the staple unit downward by one bin, if repeat stapling operation (CNTSP) becomes 0, it is checked whether it is double-stapling, and if not, r S T P L' I
The J routine ends. In the case of double-stacking, the already explained subroutine rPST2J is executed to move the stapler unit to one position sensor 510 in the X direction and finely adjust it.

Next, copy counter [C
After setting the value of the counter (NTCP), execute the stable operation subroutine rsUB400J, and set the value of the counter (CNTSP).
After checking I-1 (1: cNTsP)-0, if it is not 0, a subroutine fsP510J for moving the stapler unit upward by one bin is executed, and the stable operation is repeated.

After that, when (CNTSP) = O, the subroutine r
sTPLl'' ends L, 24th r: Returns to the jJ main routine, then returns to B in FIG. 21, and enters a standby state.

The stapler 13 is provided with a staple end sensor (512) 32 for detecting the absence of staples. Even if this needle end sensor (S12) 32 detects that the needle is missing, it is still 7 at that point.
Approximately 0 to 100 stitches remain.

The staple-free check of the stapler 13 is performed only when the stable mode is selected, as shown in FIG. Therefore, there is a concern as to whether it is necessary to perform a needle-missing check during stable operation, but as described above, even when the needle-missing sensor operates, approximately 70 to 100 stitches remain. The number of sorter bins is compatible with 20 bins or 40 bins even in 2-stack mode, and the machine is designed so that there will be no interruption of needle removal during the stable operation of copy paper, so there is no need to worry about running out of needles midway. do not have.

Therefore, during stable operation, the needle end sensor (312) 3
Even if the machine 2 detects a staple-free state, the stabilization of the job can continue, and when all the stabilization for the ejected paper is completed and the printer enters the standby state, it checks the sensor and displays the staple-free display and The following copies are prohibited.

The operation timing of each part during auto stable operation is 4th.
As shown in FIG. 0 and FIG. 41. Note that FIG. 40 shows the operation timing of the one-shot stable operation, and FIG. 41 shows the operation timing of the two-shot stable operation.

〔effect〕

According to the present invention, the stable automatic selection switch S15 is turned to O.
If you select N and are in automatic stable selection mode, even if you forget to set the stable mode, it will automatically switch to the stable mode when you set the sort mode, eliminating the need to do the stabilization later. . This further improved administrative efficiency.
