The image is sent to a predetermined position on the contact glass 5, an image is formed on the photoreceptor 7 by reading by the optical system 6, the image is transferred to copy paper fed from the paper feeder 8, and it is reversed in the conveyance path 9 so that the image surface The bins 10 of the sorter 3 are sequentially discharged from above with the bins 10 facing downward. then 2
The same process is repeated for the 1st sheet of originals and subsequent originals. When all the originals have been copied, the copied sheets are stored in the bins as many as the initially set number of copies, with the pages arranged in order. In other words, collation is completed. In stack mode, multiple copies of the first page are stored in the first bin, multiple copies of the second page are stored in the second bin, and the copies of each page are stored in separate bins. be done.

The sorter 3 is provided with a stapling device 11, as shown in FIG. 2, for example. The stapling device 11 is attached to 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 10 has copy paper 16 fed by a feed roller 15.
It can be formed as a tray to carry the. The tray 10 has a stopper 1 provided on the end face on the stapler 13 side.

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 50. At this time, the gap portion of the copy paper 16 is placed on the holder 9 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 500 causes the tray 10 to move backward and the copy paper 16 to be separated 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 and detached therefrom.

The needles in the needle cartridge 27 are fed by a feed belt 29 driven by a drive motor 28.

The arm 30 is swung up and down by the drive motor 28, which causes the head 31 to move up and down and strike the needle 26 against the pedestal 19. The needle binds the copy paper 16 like a stapler.

A needle end sensor (S12) 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 binding positions for 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 IO at a predetermined position in one corner with a staple 26. Furthermore, if the first stitching position is when the staples 26 extend horizontally to the vertically long copy sheets 16 as shown in FIG. position) A second fine position (diagonal position) B in which the needles are tilted approximately 45 degrees with respect to the first binding position, and a third binding position (vertical position) in which the needles are bound in a vertically extending position with the needles tilted 90 degrees with respect to the first binding position. )C. In this case, the stapler 13 is
, and the angular position can be changed to 45°. The switching positions are not limited to these three positions, but may also be switchable to any angular position.

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

A gear 37 is fixed to the central shaft 33, and this gear 37 is attached to a motor (M3) supported by a bracket 38 on the base 12.
It meshes with a drive gear 40 attached to 39 and is rotated.

The stand 12 has a sensor at a predetermined switching position, for example, the first switch position.
Horizontal position sensor (S4) 41 for binding position (horizontal) and diagonal position sensor (S6) 4 for second HJ binding position (diagonal)
2, and a vertical position sensor (S5) for the third elaboration position (coiling)
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 mounted on the auxiliary base 36, and this thumbscrew 44 is screwed into the base 12 at a predetermined position. The position is fixed by screwing it into the hole 45 or pressing it against the stand I2, and when changing the direction, loosen the thumbscrew 44, move the auxiliary stand 36, and tighten the thumbscrew 44 to fix it in 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.

The stapler 13 not only can adjust the direction with respect to the copy paper as described above, but also can adjust the direction of the copy paper as shown in No. 101jJ.
f! PI alignment, that is, when the feeding direction of the copy paper by the feed roller 15, for example, the lateral direction of the copy paper, is the X direction, the position can be adjusted in the X direction and the X direction orthogonal to the X direction. For this purpose, as shown in FIG. 11, an auxiliary stand 36 or an auxiliary bracket that makes the auxiliary stand rotatable is fixed to the stand 12 with screws 46, and a long hole 47 in the X direction of the auxiliary stand 36 or the auxiliary bracket is formed. Insert screw 46 into. Thereby, the position of the stapler 13 in the X direction can be easily adjusted by hand. Furthermore, the stapler 13 is placed on the auxiliary table 36.
is formed so as to be fixed with a screw 48, and the stapler 13
Insert the screw 48 into the long hole formed in the X direction. screw 4
By loosening and tightening 8, the position of the stapler 13 can be easily adjusted manually in the X direction. 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.
The auxiliary base 36' is fixed to a support 51 fixed to the auxiliary base 36', and the auxiliary base 36' is screwed to a feed screw 54 which is rotatably supported by the support 51 and rotationally driven by a motor (M3) 53 serving as a first driving member. By engaging the stapler-1
3 can automatically adjust the position in the X direction.

Similarly, the auxiliary base 36' is slidably guided in the X direction by a guide rod 55 fixed to the base 12, and the auxiliary base 36' is threadedly engaged with a feed screw 56 rotatably supported on the base 12. When the feed screw 56 is rotated by a motor (M5) 57 serving as a second driving member, the auxiliary table 36' 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.

For example, as a 6-position home sensor (S7, S8) in which a position home sensor (S7, S8) is provided to automatically control the position of the stapler 13 in the X direction and the X direction, the sensor shown in FIGS. As shown in FIG.
Arranged as shown. In other words, as a position home sensor (S8) for X-direction control, a transmission type photo ink converter 58a is fixed to the stand 12, and a shielding plate 59a is attached to the auxiliary stand 3.
Fix it at 6'. Also, position home sensor for X direction control (
In S7), the transmission type photo ink converter 58b is fixed to the auxiliary stand 36', and the shielding plate 59b is fixed to the bracket 49. The shielding plate 59 is a transmission type photo ink converter 58
When the shielding plate 59 blocks the light from the transmission type photointerrupter 58, it is turned OFF, and when the shielding plate 59 is away from the transmission type photointerrupter 58, it is turned OFF.
It becomes N. These position home sensors (S7, S8) detect the reference position of the stapler 13 in the X direction and the X direction.

In the standard state of the copying machine, for example when the main switch is ON, the motor (M) is moved so that the stapler 13 comes to the reference position.
3) 53 and motor (M5) 57 are controlled.

By pressing the position adjustment switch placed on the operating section, motor (M3) 53 and motor (M5) 57 are driven, and 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 positional adjustment and direction adjustment in the X direction and the X direction.

An operation unit, for example an operation panel, provided in the copying machine main body 2 can be configured as shown in FIG. The mode can be checked depending on the operation.

A 10 key (numeric keypad) 101 is a key for setting the number of copies, and the set value is displayed on the set number display section 102. The actual number of copies is displayed on the copy number display section 113. The C/S key 103 is a key for returning the number of sheets set to 1, and also functions as a copy interruption key. The print key 104 is a copy start key, and is valid when the printable display is lit, and invalid when the printable display is lit.

The bin paper presence display 105 lights up when there is paper in the bin of the sorter when a stapling mode (automatic) is selected, which will be described later, and at the same time, it becomes a display indicating that printing is not possible. The reason for this is that there is a limit to the number of sheets that can be stapled by the stapler (for example, in this embodiment, it is set to 30 sheets), and when it is unclear how many sheets of paper are in the bin, stapling is prohibited.

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

In case of binding using a stapling device, a stapling mode selection key 107 is provided, and after copying is completed, the copied items in each bin of the sorter are automatically transferred to the stapler according to each stapling condition on the right side of the operation panel. 13.

When the manual staple key 10B is turned on with the staple selected, offline stapling can be performed.

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.

The staple position X key 111 and the Y key 112 are for adjusting the stapling position, and the stapling position from the edge of the paper can be adjusted in each of the X and Y directions.
This is possible in response to each pressing of the stapling direction key.

A schematic control block diagram of the copying machine is shown in FIG. 18A.

The CPU 115 is a well-known microcomputer, and the R
OM116, RAM117 and several I10 elements 118
- 122, and also communicates with other control units 1-123 such as an automatic document feeder (ADF) to execute sequence control and arithmetic processing related to copying.

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

In this embodiment, the signals shown in FIGS. 19 and 20 are connected to the signal group A126 and the load group A127, respectively. Input/output processing is performed through 10121.122.

The signal group 8128 and the load group B129 are for the copying machine main body, and their explanation will be omitted.

ADF@Gobe 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.

51 to S14 are all photosensors (LED and phototransistor), which perform various detections inside the sorter.

Reference numeral 515 is a switch that allows cents to be sent at the user's request.

For example, the various parts shown in FIG. 20 are connected to the load group A127.

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

SQL1 is a solenoid.

Control of the copy paper processing apparatus according to the present invention will be explained using a flowchart.

In Fig. 21, when the power is turned on to the copying machine, 5TA
RT and executes the "input reading" subroutine to read 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, subroutine rSUB 10J is executed to initialize the sorter and staple devices.

In subroutine fsUB 10J, as shown in FIG. 25, subroutines rsUBo 1J to rsUB04
'' and initialize each position of the stapler. In the subroutine rsUBOIJ, as shown in FIG. 26, the direction home sensor (also the horizontal position sensor in the example shown) is used to set the basic staple direction.
(S4) The motor (M3) 39 is driven in the reverse direction until 41 is turned ON.

The direction home sensor is not limited to the horizontal position shown in the figure, but can be appropriately selected from a vertical position, diagonal position, etc. In the subroutine FSUBO2J, as shown in FIG.
Performs processing to return the staple position in the direction to the home position,
This control determines the home position using a position home sensor (S8), that is, a shielding plate 59a fixed to the auxiliary stand 36' and a transmission type photo ink converter 58a fixed to the stand 12.

If the position home sensor (S8) is ON, the motor (M5) 57 is driven forward, and the position home sensor (S8) is turned ON.
8) is turned OFF, the motor (M5) 57 is reversed again, and the position home sensor (s8) is turned ON.
) 57 OF F L7, determine the home position.

Subroutine fsUBO3J performs processing to return the staple position in the X direction to the home position, and subroutine fsU
This is similar to the control of BO2J. In this case the motor (M4)
53, a transmission type photointerrupter 58b and a shielding plate 59b forming a position home sensor (37) are used. In subroutine rsUBO4J, stapler-1
Control is performed to determine the home position in the vertical direction of step 3. The motor (M2) is rotated in reverse until the sensor (S2) is turned on to raise and position the platform I2. Subroutine rsUBO
After 4J counter (CNTM) and flag (FBPE)
Reset and exit.

Next, execute "input reading" again, check the keystrokes for each stapling mode on the operation panel, and set the mode and LED display.

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

At this time, the sorting mode is automatically selected, sorting is performed, and ED is also turned on. Also, the stapling LED is turned OFF.Next, when the two-stapling mode is selected by the two-stapling key 109, the two-stapling LED is turned ONL, and at the same time, the horizontal stapling direction is automatically selected.

In the case of two-staple mode, vertical and diagonal stapling are structurally impossible, so horizontal stapling is automatically performed.

If the staple direction is not double staple, check whether the staple 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 stapling direction when the stapling mode is selected is preferentially selected as the horizontal direction.

Next, the staple position, the X key 111, and the Y key 112 will be explained. In this embodiment, as shown in FIG. 10, the standard position of the staple (one end of the staple) is 6 mra from the edge of the paper in both X and Y.
On the other hand, with two barrel steps, both in the direction and in one direction,
It can be adjusted in two stages, and is set using the X key 111 and Y key 112. If the X key 111 is not turned on, the normal LED indicating the normal position is turned on, and the X key 11 is turned on.
When 1 is turned ON once, the +2 Peng LED is first turned ON, and the normal LED is turned OFF. When turned on twice, +2n+
Set the m LED to 0FFL and turn on the +4 mm LED. After that, switch the 12mm LED the third time, and the 14mm LED the fourth time, and turn it on 5 times to return to normal L.
ED ONL, return to normal.

Next, regarding the Y key 112, similarly to the X key 111,
Set the mode and selectively light the 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, a sorter turbine paper presence check is performed. If there is no paper, the bin paper presence display LED is turned OFF, and the copy prohibition flag is also turned OFF. If there is no paper, the copy prohibition flag is turned ON.

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

If there is paper and the manual staple key 108 is ONL, the copy enable flag is turned ON and the stapling operation subroutine rsTPL2J is executed.

Here, if there is no paper in the sorter bin, the manual stapling key 108 cannot be turned on, so it is possible to prohibit the stapling operation when there is no paper, and it is possible to prevent stapling errors due to no paper stapling.

In addition, since auto-stapling copying is prohibited when copying is done, it is possible to prevent mistakes such as binding the previous copy paper together and stapling mistakes due to excess paper.

Furthermore, by activating the manual staple key in the preload state, offline stapling (for example, stapling is enabled by placing paper other than copy paper in the sorter bin) is possible.

In the tBlue f7 rsTPL2J, first, as shown in Fig. 31, the manual staple counter (CNT
M), and if the data is O, execute the subroutine "PSTIJ" of positioning operation 1. If it is not 0, no positioning operation is performed.This counter (
CNTM) is normally 0, but as will be explained in detail later, manual stapling can be performed either for each staple or for continuous stapling, and if it is interrupted after each staple, positioning operation 1 is not performed when moving to the next operation. That's how it is.

The subroutine rPSTIJ of positioning operation 1 is as shown in FIG.
Execute J. In rsUB I OJ, as already explained, the stapler unit is returned to its home position.

Next, subroutine jsUB 100J is executed.

In subroutine rsUB100'', 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 (S5
)43, and if it is not turned on, the motor (M3
) 39 for normal rotation, and when the vertical position sensor (S5) 43 is turned on, the motor (M5) 39 is turned off.

If it is horizontal, the horizontal position sensor (S4) 41 is set to O.
Rotate the motor (M3) 39 in the reverse direction until it reaches N. In the diagonal mode, if the horizontal position sensor (S4) 41 is ON while the diagonal position sensor (S6) 42 is not ON, the motor (M3) 39 is rotated forward, and then the diagonal position sensor (S6)
)42 turns on, and the horizontal position sensor (S4)
If the sensor 41 is OFF, the motor (M3) 39 is reversely rotated to control the position so that the diagonal position sensor (S6) 42 is turned ON.

Next, the subroutine fsUB200 is executed.

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

First, it is checked whether the set value is 211Iffl, and if yes, the timer TI is set to Tl=100ms.

Or if the set value is 4 cabinets, timer T1 is TI = 200
Set to ms. If the set value is neither 2 mm nor 4 +++ m, this routine ends. After the timer point, start the timer, then check whether it is in the Φ direction or the e direction, and if it is in the e direction, rotate the motor (M5) 57 in the forward direction, wait until the timer time up, and then start the motor (M5).
) 57 is turned off. Similarly, in the e direction, the motor (M
5) Reverse the rotation of the motor (M5) 57 and wait for the timer to turn off in the same manner, then turn off the motor (M5) 57. -For example, the position control in the Y direction is 20m by driving the motor (M5) 57.
This can be done at a speed of m/s.

When the subroutine rsUB200a ends, it is next checked whether the two-shot mode is in effect. If it is not the two-shot mode, subroutine rsUB300J is executed.

Subroutine rsUB300" is subroutine rsUB
This is almost the same as 200J, and the position adjustment control is in the X direction, and positioning is performed under the control of the motor (M4) 53. In the case of the double-stapling mode, after the motor (M4) 53 is turned on in normal rotation until the staple unit reaches the position where the sensor (S9) is turned on, the subroutine rsUB3001 is similarly executed, and this subroutine rPsTIJ is ended.

In subroutine rsTPL2J, subroutine rP
When sTIJ is executed, subroutine rsUB40
Execute 01. This subroutine moves the bin to the stapling position, performs the stapling operation, and returns the bin.

In FIG. 37, first 5QL1 is turned on. By driving solenoid SQL 1, the bin is moved to the stapling position. 5 After turning ON the OLI, set the timer TI to T.
Start by setting I = 200ms, and when the timer TI times up, the stapler paper detection sensor (513
). 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 makes it possible to finish the stapling operation by confirming that there is no more paper on the bin even if it is not known how many pins there are in the paper during manual stapling. or,
Even during auto stapling, if for some reason a sheet of paper is removed from a bin in the middle, the job can be moved to the next bin without the stapling operation.

In FIG. 3, the stapler-paper detection sensor (S13)
When 20 is OFF, the bin paper empty flag (FBPE) is set and SQL 1 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 motor (ML) 28 is driven and turned off until the stapler drive home sensor (Sll) is turned on again. 0FFI,
The timer TI is operated until the bin returns to the predetermined position, and this subroutine rsUB400J is ended.

When the subroutine ``SυB4O0J'' ends, the contents of the manual staple counter (CNTM) are increased by 1 and the process moves to the next step.

Next, check whether the manual staple key is kept on.

If ONL is left alone, the above-mentioned bottle paper empty flag (FBP
Check E) and if it is not “1”, subroutine rsU
Run B500J.

This content is a ladder that allows manual stapling operations to be performed continuously if the manual stapling key continues to be turned on after one staple operation is completed. 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 unstapled. Subroutine rsUB500
1 is a subroutine that rotates the motor M2 forward for 700 m5 and moves to the next bin position, as shown in FIG.

- For example, when the distance between bins is 35 thresholds each, motor M
The stapler unit moving speed according to No. 2 is 50 m/s. As mentioned above, after the stapler unit is moved to the next bin position (downward) by subroutine rsUB500J, the routine returns to execute subroutine rsUB4001 again, the stapling operation and the movement of the staple unit are repeated, and then the counter (CNTM) is Continue count amplifier, manual staple key is OFF
If so, move on to the next step.

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

Next, check the two-shot mode. If it is not a double hit, the subroutine rsTPL21 ends. When hitting two shots, check the flag (FBPE) next.
If the value is FBPR)-1, the final bin in the double-stack one-sided mode was pear-free, so it is necessary to return the staple unit to the previous bin position (above), and subroutine rsLI85101 is executed here. subroutine r
The sUB510J executes the subroutine f as shown in FIG.
The only difference from sUB500J is the rotational direction of the motor, and this is a subroutine for moving the stapler unit upward by one stage of bins.

After executing the subroutine rsUB510J, the flag (FB
PE) is reset and moves to the next step. Also, even if (FBPE)=O in the previous (FBPE) check, the process moves to the next step.

Next, subroutine rPsT2J is executed.

The subroutine rPsT2j, as shown in FIG.
The stapler unit is moved in the X direction, and the motor (M4) 53 is driven to the position where the sensor (510) is turned on. The sensor (SIO) is the other position reference when hitting two shots. Sub 7L after sensor (SIO) 0N (7)
, -+nrSUB300'', the position in the X direction is finely adjusted, and the subroutine rPsT2J is ended.

Next, subroutine rsUB400a is executed to perform a stapling operation. After stapling, counter (CNTM)
-1 and check whether (CNTM) is 0. 0
If not, there are remaining sheets, so subroutine rSUB
Execute 510J and move the stapler unit upwards 1
Move by bin.

Thereafter, the subroutine rsUB400'' is repeated and when the counter (CNTM) reaches 0, it means that the entire double hit is completed, and the subroutine rsTPL2J is terminated.

In addition, in the case of double-stapling when the manual staple key 10 B is not left on, move the staple unit in the X direction from the middle of the bin as described above, and similarly tap the other staple of the double-stapling. You can continue printing any number of copies.

Also, when the manual staple key 108 is not ONL and does not hit twice, -dan this subroutine r
After completing sTPL2J, stapling of the fire bottle is possible. This is because the counter [CNTM] at the beginning of subroutine rSTPL2J is not 0, so initialization of the stapler, that is, subroutine rPsT1a
This is to avoid doing so.

When the "subroutine rsTPL2" is finished, the main routine is returned to, and as shown in FIG. 22, "input reading" is executed again, and other copying modes are set and processed.This includes, for example, the variable magnification mode and density adjustment. Since there is no need for explanation in this embodiment, the explanation will be omitted.

In Fig. 21, we have explained the case where the staple is selected by checking the staple selection, but if the staple is not selected, it jumps to number A, and as shown in Fig. 22, there is no staple number 1, so the staple mode is activated. To cancel. That is, first, subroutine rSUB 10J is executed to initialize each position of the stapler unit, and then all LEDs related to the stapler are turned off.

After that, check the sorter key, turn the sort mode LED ONL for sorting, and stack L for stacking.
Turn on ED, leave it as it is if it is not selected, set the bin paper presence display to 0FFL, set the copy prohibition flag to 0FFL, and proceed to the input reading 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 made here, the print prohibition display is turned ON, and the process returns to B. 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 unless the paper is removed or the staple mode is canceled. The copy prohibition flag is also turned on under other conditions, such as when the heat fixing device does not reach a predetermined temperature, but this will not be described in detail.

When the copy prohibition flag is cleared, the print permission display is turned to O.
Press N and check the print key is ON. If the print key is ONL, it will 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 document set 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 center sensor (S20) is ON, it sends a document feed ON signal to the ADF, waits until a document feed end signal comes from the ADF, and then turns OFF the document feed signal.

Next, the ON check of the ADF document set sensor (320) is performed again. Here, the document set sensor (S20) is 0.
FF1. , it turns out that the number of originals set in the ADF was one, so the next check is,
If the staple mode is set, the staple mode is canceled, and if the sort mode is set, the sort mode is canceled. This is because stapling and sorting a single 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 (S20) is ON, it is known that there are two or more originals, so the aforementioned stapling selection and sorting mode selection check is not performed.

Next, check the sort mode selection again.

If the sort mode is selected, check whether the automatic staple selection switch (S15) is ONL and turn it ON.
and the copy cent sheet D (CNTST) is “2” or more, the sort mode is canceled and the staple LED is turned on.
NL, the staple horizontal direction LED is turned ON, and the normal position LEDs of the staple positions X and Y are turned ON.

In other words, the mode is switched from sort mode to the standard state of staple mode. This is so that when there are two or more copies per copy in sort mode, they are often stapled after copying, so even if you forget to staple the stapler, you can auto-staple. This mode is determined by the user's preference, so
A switch (315) is provided to allow the user to select an automatic staple selection mode.

After the document feeding of the ADF is completed and various automatic switching is completed, the document counter (CNTOL) is cleared once, l is set, and then the process moves to the next step.

In FIG. 24, first the copy counter (CNTCP)
Clear.

Next, after executing a series of copying processes (not detailed) such as document exposure, development, paper feeding, transfer, separation, and cleaning, the copy counter (CNTCP) is incremented by +1, and then sorting or stapling is selected. If so, the paper is discharged to the bin of the sorter with the number corresponding to (CNTCP).If it is not sorted or stapled, the paper is discharged to the same bin.

Next, the set counter and copy counter are CSNTST)
If ≠ (CNTCP), the copying process for the original has not finished, so the next copying process is executed and (SNTS
T) - [Repeat until CNTCPE. (SNTST)=
(When CNTCPI is reached, if the stack mode is selected, the copy paper output slot for the next original is set to (CNTOL).)
) and add 1 cent to the sorter's bin.

Next, check the document set sensor (S20) of the ADF. If the document set sensor (S20) is ON, there is the next document, so turn on document ejection and document feed, and eject and feed the document. Wait for the process to finish, then eject and feed the original. Next, add +1 to the manuscript counter (CNTOL),
As a result, if the document counter (CNTOL) is not 31, the process returns to the copy routine again and repeats this process.

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

Then, select the sort mode and turn on the sort LED.

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, when the ADF document set 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 B and enters a standby state in which the next copy condition is accepted, etc.

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

In the subroutine rsTPLIJ, as shown in FIG. 30, the contents of the copy counter (CNTCP) are first placed in the staple counter (CNTSP). Next, a stapler initialization subroutine rPsTIJ is executed.

After that, the stapling operation subroutine rsUB400J
Execute.

Next, add 1 to the counter (CNTSPI) and set the counter (
CNTSP) = 0 is checked. Since this counter matches the contents of the copy counter described above, it becomes 0 when stapling is performed for the number of copies. When it is not 0, the stapling operation is repeated after executing the subroutine vSUB500J for moving the staple unit downward by one bin.

When (CNTSP) becomes O, it is checked whether it is a two-shot or not, and if not, rsTPLIJ/Rechin is finished. If it is double-stapling, execute the already explained subroutine fPsT2J and set the X of the stapler unit.
Move to one of the position sensors (S10) in the direction and make fine adjustments.

Next, copy counter CC to the counter (CNTSP) again.
After setting the value of NTCPJ, execute the stapling operation subroutine rsUB400 and set the counter (CNTSP
)-1, then after checking (CNTSP) = 0, if it is not 0, move the staple counter upward by one bin subroutine rsP510. Execute + and repeat the stapling operation.

After that, when (CNTSP) = 0, subroutine 7S
TPLIJ is finished, the process returns to the main routine in FIG. 24, and then returns to B in FIG. 21 to enter a standby state.

The stapler 13 is provided with a staple end sensor (312) 32 for detecting the absence of staples. Even if this needle end sensor (S12) 32 detects that there is no needle, 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 staple mode is selected, as shown in FIG. Therefore, there is a concern as to whether or not it is necessary to check for missing staples during stapling operation, but as described above, even when the stapleless sensor operates, approximately 70 to 100 stitches remain, so in this embodiment, The number of sorter bins is 20 bins or 40 bins even in 2-stapling mode, and it is designed so that no staples will be interrupted during the stapling operation of copy paper, so there is no need to worry about running out of staples in the middle. Therefore, even if the staple end sensor (S12) 32 detects a staple-less state during stapling operation, stapling for that job can be continued, and when all the stapling for the ejected paper is completed and the standby state is reached, The sensor will be checked and no needle will be displayed and the next copy will be prohibited.

The operation timing of each part during auto stapling operation is 4th.
As shown in FIG. 0 and FIG. 41. Note that FIG. 40 shows the operation timing for single-stapling, and FIG. 41 shows the operation timing for double-stapling.

In the above embodiment, a copying machine has been described, but the present invention is not limited to copying machines, but can be applied to various image forming apparatuses such as facsimiles and printers. In this specification, the term "copy paper" is used in a broad sense to include not only paper that has been copied using a copying machine, but also paper on which various types of images have been formed.

〔effect〕

According to the present invention, the stapler can be easily switched and set in the direction desired by the operator, making it possible to staple in the desired direction.

According to the present invention, by setting a reference direction in advance and automatically setting the direction of the stapler to the reference direction when selecting a stapling mode, it is possible to staple in the direction selected by the previous operator without forgetting to set the direction. It can be prevented from being put away.
