Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electrophotographic copying machine that uses one numerical display to display a plurality of quantities.

(Prior Art) Some electrophotographic copying machines are equipped with a numerical display (such as a 7-segment LED) on an operation panel to display the number of copies.

On the other hand, electrophotographic copying machines are sometimes provided with special functions such as binding margin and analogue deviation. The binding margin function is to copy with a preset binding margin width margin at the edge of the copy paper, and the anamo bias function is to copy at different magnifications in both the vertical and horizontal directions. Stretching an image in one direction, or compressing it into a flat image. If the binding margin, analog magnification (ratio of vertical and horizontal magnification), etc. are not constant and can be set in units of mm or percentage, the above copy number display area can be shared and the binding margin key can be set for a specific period (for example, when the binding margin key is The display panel can be simplified by displaying it only while the button is being pressed. Since these special functions are set before the copying operation, they may be used in common with the copy number display.

(Problems to be Solved by the Invention) Electrophotographic copying machines are usually equipped with an interrupt function, and when the interrupt key is pressed in a hurry, the copying process so far is temporarily stopped. You can make a quick copy.

Pressing the interrupt key again cancels the interrupt function and resumes copying before the interrupt.

By the way, if a special function such as a binding margin is used in the copying before the interruption, a copy error may occur when the interruption is canceled due to forgetting the set binding margin.

An object of the present invention is to display the setting value (binding margin, etc.) of the special function when canceling the interruption, if the copy before the interruption uses a special function (binding margin, etc.). To provide an electrophotographic copying machine.

(Means for Solving the Problems) The electrophotographic copying machine according to the present invention includes an interrupt instruction means for instructing interrupt copying or cancellation thereof, and a special copying machine for instructing special copying requiring setting of parameter values. copy instruction means; setting means for setting a parameter value for special copy when special copy is instructed by the special copy instruction means; displaying a parameter value when the parameter value is set by the setting means; During the copy operation, the display means displays the number of copies, and when interrupt copying is instructed by the interrupt instruction means during special copying, the setting is made in the special copy before interrupting when interrupt copying is canceled. and interrupt release control means for displaying the parameter values that have been set on the display means.

(Function) Displays parameter values (binding margin, analogue bias, etc.) of special copies (binding margin, analogue bias, etc.) on the display means during a specific period (period in which the parameter values are set by the setting means). In an electrophotographic copying machine, when an interruption is made during special copying, a parameter value before the interruption is displayed on a display means when the interruption instruction means cancels the interruption copying.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a schematic sectional view of an electrophotographic copying machine according to the present invention. This electrophotographic copying machine consists of a copying machine main body 1, a stand 2 on which the copying machine main body is placed, an automatic document feeder (ADF) 300 installed as an option, and a three-stage paper feeding unit 1000.

The copying mechanism of the copying machine main body 1 is similar to that of a conventional electrophotographic copying machine. A photoreceptor drum 2 that can be rotated counterclockwise is disposed in the center of the copying machine main body l.A main eraser lamp 3, a sub charger 4, and a sub eraser are arranged around the photoreceptor drum 2. Lamp 5, main charger 6, developing device 7, transfer charger 8, transfer paper separation charger 9, blade type cleaner device I
O, etc. are arranged one after another. The photoreceptor drum 2 is a drum having a photoreceptor (for example, selenium) on its surface, and - for each copy, it is irradiated with light by an eraser lamp 3.5, charged by passing through a charger 4.6, and then, The image is exposed to light from an optical system, which will be explained next. The motor M1 drives the photosensitive drum 2 and the like. Note that a color toner detection sensor 411 is attached above the developing device 7.

The optical system is installed below the document table glass 11 so that the document image can be scanned. The optical system includes a light source 12, a first mirror 13, a second mirror 14, a third mirror 15, and a projection lens 1.
6 and a fourth mirror 17. The original image is line 1
Each mirror 13. as shown at 8. +4, 15, 17, and reaches the photosensitive drum 2. Fixed position switch SW5
00 is provided to detect whether the optical system is at a predetermined position during scanning. An automatic exposure sensor 19 is attached above the projection lens 16, and the intensity of the reflected light from the mirror 15 is measured to detect the original density.

The magnification is set by moving the projection lens 16 in the optical axis direction using a motor M4. Note that the motor M3 drives the optical system. When the copying magnification is n, the light source 12 and the first mirror 13
, the motor M3 rotates (
v/n) to the left, and at the same time, the second mirror 1
4 and the third mirror 15 move to the left at a speed of (v/2n).

Along with this movement, the image is exposed from the fourth mirror 17 onto the photosensitive drum 2 in a slit shape.

On the left side of the copying machine main body 1, an automatic paper feed cassette 20 is installed in the upper part, a three-stage paper feed unit 1000 is installed in the lower part, and a manual paper feeder 21 is installed in the upper part. The three-stage paper feeding unit 1000 is installed as an option in place of the second automatic paper feeding cassette, which is standard equipment for feeding low-quality sketches. The copy paper in the automatic paper feed cassette 20 or the manual paper feed section 21 is selectively fed into the copying machine main body 1 by the respective paper feed rollers 22 and 23, passes through each pair of transport rollers 24 and 25, and is crimped. It is conveyed to the timing roller 26, which is in the current state, and is temporarily on standby there. Note that the paper feed roller 30 is used for feeding paper at a low draft level.

During transfer, the copy paper fed by the timing roller 26 comes into close contact with the photoreceptor drum 2 in the transfer section, and the toner image is transferred by the corona discharge of the transfer charger 8, and then the toner image is transferred by the corona discharge of the separation charger 9 and the transfer. The paper is separated from the photosensitive drum 2 by its own stiffness. Subsequently, the copy paper is conveyed to the right as the belt 27 rotates clockwise while being sucked onto a conveyor heald 27 equipped with an air suction means (not shown). Next, the toner image is melted and fixed by passing through a fixing device 28. Then, it passes through a pair of discharge rollers 29 and is discharged to a tray 30 outside the copying machine main body 1 or a collating machine (not shown).

(d) Special copy mode (binding margin copy mode, analog copy mode, and book copy mode) Binding margin copy mode> In the binding margin copy mode (see Figure 8), the binding margin a of the specified width is It can be placed on the right side.

If there is no margin in the manuscript, providing a binding margin will make it easier to bind the copies.

In this embodiment, two modes are provided. In the first mode, the image is simply moved by the binding margin (see Figure 8).
See A). In this mode, if the protruding portion of the document d is not a margin, image loss occurs. In the second mode, in order to eliminate image defects, the reduction ratio (-(paper length - binding margin)/paper length) is calculated from the width of the copy paper (paper length) and the binding margin, and the Determine the magnification accordingly.

<Anamo copy mode> In the analog copy mode of this embodiment (see Figure 9), the width direction of the copy (depending on the lens position) is kept the same, and only the speed of the scanner is changed to create an image in the length direction. control to shorten or lengthen. Note that if the analog magnification (aspect ratio) is not within the range of 95% to 105%, the resolution will drop, so a warning message 11 will be displayed to the user.
Do 0.

In order to obtain stable copies no matter what the analog polarization magnification, it is necessary to insert a special lens in the optical path.

<Book copy mode> In the book copy mode (see Figure 10), when you open a book and make copies, both pages of the spread (side A and side 3) are copied.
・Sequentially copy with one button operation.

(e) Operation of the copying machine main body The contents of the CPU program that controls the copying machine main body 1 will be outlined below.

<e-]>Main Routine FIG. 11 shows a schematic flowchart of the CPUI. C
When the PUI is reset and the program starts, the first step is to clear the RAM, set various registers, etc.
Initialization is performed to initialize the PUI and set the device to the initial mode (step Sl).

Next, an internal timer that is built into the CPUI and whose value is set in advance as an initial setting is started (step S2). Next, various processing parts manual feed door processing S
3. Cassette insertion processing S4, copy operation S5, automatic paper selection S6, automatic magnification selection S7, key processing S
8 and display processing S9 are performed sequentially. Next, CPU2,3
．． 4 (step 510).

When all subroutine processing is finished, wait for the end of the internal timer that was set first (step 5ll).
, 1 routine is completed and the process returns to step S2. The length of time of one routine is used to count the various timers that appear in the subroutine. (The various timer values determine the end of the timer depending on how many times this one routine is repeated.) <e-2> Manual feed door processing routine FIG. 12 shows the manual feed door processing routine S3.

First, the switch 410 that detects the opening/closing of the manual feed door is turned OFF.
It is determined whether or not the F edge, that is, opening of the manual feed door has been detected (step 521). If not detected, the process immediately advances to step S31.

When detected, the manual feed display 112 lights up (step 5).
22). Since the copy number display 101 switches to the function of an addition counter, the initial value "0" is displayed (step 523). Also, it is determined whether the L'ED 144 is ON, that is, the "binding parishioner automatic reduction mode" is determined (step 524), and if so, the mode is canceled and the mode is automatically switched to the "binding margin creation mode". Call the binding margin introduction routine (see Figure 27) (step 525).
. This is the "Automatic reduction mode for binding parishioners", which is a mode that automatically calculates the reduction rate from the length of the paper and the binding margin, and what size (length) of paper is inserted in the case of manual copying. Since the binding parishioner is not sure, the automatic reduction mode is automatically canceled.Next, the book copy mode selection is displayed and it is determined whether ED14s is lit, that is, whether or not the book copy mode is in step 826. ), if so, since the manual copy size is not known, it is not possible to perform a book scan, so turn off the LED 145 in step 52.
7) The book B side signal and the book A side signal are set to 0 (step 528), and the book copy mode is automatically canceled.

Next, when the CIN edge of the switch 410 is detected, that is, the manual feed door is closed (step 531), the manual feed display 1 is detected.
Step 532), copy number display 10
1 to 1 (step 533).

And then return.

<e-3> Cassette insertion process FIG. 13 shows the cassette insertion process routine S4. L.E.
When D14.4 is ON, that is, the "Bound Samurai automatic reduction mode" is selected (step 541), if the upper cassette is selected (step 542), the upper cassette is pulled out (step 543), or the lower cassette is selected. If the lower cassette is removed (step 544), the copy magnification is set to the original magnification (before automatic reduction) at each edge (step 545), and the magnification is displayed (step 846). , is sent to the CPU 2 (step 547).This is because the copy magnification, which was determined by the paper length and binding margin of the selected cassette before the cassette was removed, cannot be calculated automatically after the cassette is removed. This will return the image to its original magnification.

Next, the upper cassette (step 551) or the lower cassette (
When a new paper is inserted (step 552), the paper feed port is automatically selected (steps S53 and 554).
, automatically calculates the reduction magnification (a magnification that does not cause image loss based on the paper length and binding amount) (Step 555), the CPU
2 (step 856) and display the magnification (step 557).

The above explanation is about the upper and lower two-tier cassettes as standard equipment, but if the three-tier paper feed unit 1000 is installed as an option, the three-tier paper feed unit 1000

shows. When the LED 4.5 is lit, that is, in the book copy mode (step 561), when there is an edge of the document inserted into the ADF tray (step 562), the LED 145 is turned off (step 563), and the book copy mode is canceled (step 564). . That is, the book scan control becomes meaningless when AD'F300 is used, so it is automatically canceled.

If you press the manual copy (step 571), press the ON edge of the print button 50 (step 572).
, if the ADF is not used (step 573), the copy start flag is set to "bi" (step 574). If the ADF is used (step 572), if there is a document in the ADF tray (step 575), the ADF is The start signal is set to "B" (step 876). Also, when the print button 50 is not ON edge (
Step 572), if ADF is used (Step 578)
), when the original position signal from the ADF 300 becomes "1" (step 579), the copy start flag is set to "bi" (step 580). Next, in the case of manual copying (step 571), the manual paper insertion slot Regarding the ON edge of the detection sensor SEI (step 577), the same processing (steps 973 to 876) as for the ON edge of the printer l-SW'50 is performed.

When the copy start flag becomes "1" in step S81, the main motor M1 and the developing motor are turned on, the charging charger, the transfer charger, etc. are turned on, the copy start flag is set to 0, and T-A (timer A), T- B (timer B) is set (step 582). If the overprint paper cassette is selected (step 584), the overprint paper roller clutch is turned on (step 585). If the draft paper drawer is selected (step 886), the draft paper roller clutch is turned on (step 587). If manual feed is selected (step 888), the manual feed roller clutch is turned on (step 589).

In step S91, the T-A is judged and the T-A is judged.
When it is time for A to end, the upper and lower paper feed roller clutches and the manual feed roller clutch are turned off (step 592).

In step 5101, TB is judged.

When it is time for T-B to end, if it is the binding margin creation mode (step S'102), a timer E corresponding to the amount of paper is set in order to advance paper by the amount used for the binding margin.
(Step S]03), the timing roller 26 is turned on (Step 5I04), and the scan signal is turned on (Step S105). Then, when the timer E ends (step 5106), the timing roller 2
6 is stopped (step S107).

As shown in FIG. 14(b), when the timing signal becomes "1" in step 5i11, the timing roller clutch is turned on and T-C is set (step 8
112).

In step 5121, at the timing when TC ends, the charging, scan signal, and timing roller clutch are turned off (step 5122).

In step 5131, the return signal of the optical system is “
In other words, when the return is started, it is determined whether the sensor SEI of the manual paper feed slot is on or not (step S1.32). If it is on, the next manual paper is already set in the multi-manual paper feed mode. I decided that
Create a pseudo SEI ○N edge (Step S
]33), execute the next manual copy mode. This allows manual copying to continue automatically while paper is being loaded into the manual paper feed slot.

Next, it is determined whether the multi-copy portion has been copied (step S]34), and if i:l, the copy start flag is set to "bi" (step 3135).

Then, if hook copy mode is selected, i.e.
LED] 4.5 is on (step S) 36), it is determined whether or not the B side copy signal is "1 pass" (step 5141). Step S1.42), set the A-side copy signal to "1" (Step S143), and set the copy start flag to "1" (
Step S14-4), A-side copying is performed. “0”
If so, finish copying side A (step 5I45),
Switch to three-sided copying (step 9146) and wait for the next print. Then, when the scanner returns from its home position once and turns on the home position sensor 5W500 (
Step 5145), stop the development motor and transfer,
Set T-D (step 5146).

At the timing when T-D ends (step 5I5
1), stop the main motor M1 (step 515
2). Then, the results of the processing up to now are output (step S+55).

<e-5> Automatic paper selection FIG. 15 shows automatic paper size) routine S6. The document size data detected and transmitted by the CPU 3 that controls the ADF 300 is temporarily stored in the A register (step 5161). Next, the binding margin creator automatic reduction mode select is displayed and it is determined whether 3l-ED14.4 is on (step 5I62). If it is off, the copy magnification is applied to the A register, that is, the magnification is applied to the vertical and horizontal lengths of the document stored in the A register (step 9163). If it is off, this magnification is the copy magnification that happened to be calculated based on the paper length and binding margin that were selected at that time, so first the original copy magnification (i.e. copy magnification - ((
After returning to the selected paper length - binding margin)/selected paper length)) (Step 8
164) and the A register (step 516).

It is determined whether binding margin creation + automatic reduction mode display LED + 4.4 is on or off (step 5193).

When it is off, store the length of the paper divided by the A register (original length) in the A register (step 5194).
. When the LED 144 is on, that is, in the "binding parishioner automatic reduction mode", the magnification is calculated using the value obtained by subtracting the binding substitution from the paper length as a simulated paper length, and
Store in A register (steps 5195.3196)
. This allows automatic magnification calculation with binding substitution in mind. Similarly, the horizontal magnification is calculated and stored in the B register (step 5197).

Next, the smaller magnification of the A and B registers is stored in the C register (steps 3201 to 203).

As described above, if the value of the C register obtained is outside the capabilities of the copying machine (outside the possible magnification range) (step 520
4) Set the magnification nonconformity flag to "1" (step 52

, 1427 are corrected (step 8230).

Furthermore, when the binding margin copy mode select key 82 is on, that is, when the magnification up key 71 is turned on while the binding margin copy mode select key 82 is on (step S223), 5 mm is stored in the binding margin memory. Add (step 5231). As a result, if the binding margin memory exceeds 5 mm per month (step 5232), it is corrected to 15n+m (
Step S233). In the above two cases, the change flag is set to "1" (step 5234).

If the analog copy mode select key 75 and the binding copy mode select key 82 are both off, the magnification key displays 132 to 135 and 139 to 142 are turned off (step S224). That is, since the magnification is different from the magnification stored in the magnification key, the magnification key display is turned off. Then, + is added to the magnification (step 5225). As a result, 1.4

<e-7-2> Magnification down key FIG. 19 shows the magnification down key (72) processing routine (step 5212). The magnification down key 72 is normally used to reduce the copy magnification, but if you turn on the magnification down key 72 while turning on the Anamo copy mode select key 75, it becomes a key to decrease the Anamo rate by 1%.
In addition, if the binding margin copy mode select key 82 is turned on and the magnification down key 72 is turned on, the remaining amount of binding is 5.
It becomes a down key for each mm.

When it is N, that is, when the magnification down key 72 is turned on while the binding margin copy mode select key 82 is turned on (step 5237), the binding margin memory is subtracted by 5 mm (step 245). As a result, the binding margin memory is 5m.
When it becomes smaller than m (step 3246), it is corrected to 5 mm (step 5247). Furthermore, in the above two cases, the change flag is set to 1 (step 8248).

If the analog copy mode select key 75 and the binding margin copy mode select key 82 are both off, the magnification key displays 132 to 135 and 139 to 142 are turned off (step 3238). That is, the magnification key is different from the magnification stored in the magnification key (step 5239). As a result, if it becomes smaller than 0.640 (step 5240)
, corrected to 0.640 (step 5241).

<e-7-3> Interrupt Key FIG. 20 shows the interrupt key processing routine 5213. At the ON edge of the interrupt key 61 (step 5251

Display (Japanese Unexamined Patent Publication No. 59-538
Publication No. 67). However, the former allows outside light to enter through the front door window, and the latter is expensive.

By the way, when mainly making black copies, the user can prevent copy mistakes by simply displaying whether or not it is a black copy. Also, this method is inexpensive.

FIG. 36 shows the color toner display routine 5513.

When the detection switch 411 is turned on by the magnet set only in the color toner developer (regardless of color) 6 (step 3581), the color toner display 1

(f) Operation of optical system Figure 39 (A), (B) to Figure 42 (A), (B) are schematic flowcharts of the program of CPU2 (scanner, lens control CPU) that controls the operation of the optical system. shows. In the main routine (FIG. 39), after initial settings are made (step 5611), an internal timer is started (step 5612). Next, lens control (step 5613, details shown in FIG. 41) and scanner control (step 5614, details shown in FIG. 42) are performed. When the internal timer determines that one routine has ended (step 5615) ), the process returns to step 5612.

As shown in FIG. 39(B), when there is an interrupt from the CPUI (step 5616), communication is performed with the CPUI (step 5617).

FIG. 40 shows the lens control routine 5613. In normal copying (step 5621), the lens is moved to match the copy magnification sent from the CPUI (step 5623). Anamo copy mode Serac)・When the display LED 136 is lit (step 56)
21), that is, when in "anamo copy mode" (the anamo copy mode of this embodiment is a method in which the lens is fixed at the normal copy magnification position and the magnification is varied in the scan direction by changing the scan speed), The lens is not moved to the magnification position sent from the CPU 1, but is moved to the same low position (step S622).

FIG. 41 shows the scanner control routine 5614. When the book copy mode select display LED 145 is not lit (step 5631), that is, in the normal copy mode, or when the book copy mode select display LED 145 is lit (book copy mode) and the A-side scan is being performed. case (step S 632)
, perform normal scanner control. That is, when the scanner leaves the fixed scanner position 5W (SW500) (step 9633), a timer T for lens I/alignment with the paper considering the scanning speed and a scan length timer determined by paper length x magnification are set. (Steps 5634, 635). At the end of the timer T (step S 636), the timing signal is set to "1" (step 5637), and at the end of the scan length timer (
Step 9638), set the scan signal to "0" and set the return signal to "B" (step S 639). In the case of scanning 3 sides of a book (step 5641), scan the paper length x magnification and then (step 5642) , the same processing as described above is performed (steps 8643 to 648).However, if the scanner reaches the longest scan (420 mm) before the scan length timer expires, the scan is terminated there, step S649), and return is started.

(g) l) Operation of p Figure 42 (A) and (B) show the CP that controls the ADF 300.
A schematic flowchart of U3 is shown. When the CPU 3 is reset and the program starts, the CPU 3 is initialized by clearing the RAM, setting various registers, etc., and initial settings are made to put the device into the initial mode (step 5651).

Next, an internal timer built in the CP and U3 and whose value is set in advance as an initial setting is started (step 5652).

Next, subroutines for document size detection (step S654) and other processing (step 5655) of document control (step 5653) are sequentially called. When all subroutine processing is completed, one routine is ended after waiting for the end of the internal timer set first (step 8656). The length of time of this one routine is used to count the various timers that appear in the subroutine. (Various timer values are shown in this 1.
The end of the timer is determined by how many times the routine has been counted. Furthermore, as shown in FIG. 42(B), data communication with the CPDI (step 9658) is performed by an interrupt routine, regardless of the main routine, in response to an interrupt request from the CPUI (step S657).

FIG. 43 shows the document control 5653.

When there is a document in the document tray (the document detection sensor 311 is on) (step 5661), when the ADP start signal from the CPU becomes "1" (step 5662), or when the document feed flag becomes "bi" (step 5663)
, after setting the document feed flag to “0” (step 9664
), the conveyor belt motor 301 is turned on, and the document feed motor 302 is turned on (step 9665).

Next, processing is performed in the document feeding processing routine (step 9).

).

FIG. 44 shows the document feeding processing routine 8666. When a document is fed and the document feed sensor 31O is on (step 9681), the flag K is set to "B" and the timer At
is started (step 5682). This timer AI is used to stop the document feed motor 302 in order to prevent the document from feeding the previous document and then feeding the next document. A timer value is set until the arrival.

Next, when flag K is “1” (step 8683),
When the OFF edge of the document feed sensor 310 comes, that is, the trailing edge of the document is detected (step 5684), the flag K is set to "0" and the timer A2 is started (step S
68ri). The value of timer A2 is set to a value until the trailing edge of the document reaches the predetermined position of the leading edge of the document on the document glass.

When timer A1 ends (step 5691), document feed motor 302 is stopped (step 5692). When timer A2 ends (step 5693), the conveyor belt motor 301 is stopped (step 5694), and CP
A document home position signal is sent to the UI (step 5695).

FIG. 45 shows the document discharge address routine 5671. The document detection sensor 311 detects the document in the document tray.

If it is determined that there is a next manuscript (step: 5)
701), and sets the document feed flag to “bi” (step S
702). If not, the conveyor belt motor 305 is rotated forward (step 5703), and timer B is started (step 5704). Timer B is set to the time during which the original (in the longest case) on the original glass can be ejected. When timer B ends (step 5705), the conveyor belt motor 301 is turned off (step 5706).
).

FIG. 46 shows the document size detection routine. When the document detection sensor 311 turns ON (step 5711), the timer DtJ is started (step 5712). Next, when the OFF edge of the document detection sensor 311, that is, the trailing edge of the document passes (step 5713). The timer DU is stopped (step 5714), and the value obtained by multiplying the current value by the document conveyance speed, that is, the length of the document, is stored in the A register (step 5715). If the value of the A register is 182 (mm) or less (step 5716)
, it is determined that the document size is B5 horizontal.Step 57
17), if it is less than 210 (mm) (step 87
18), it is determined that it is A4 horizontal (Step 5719)
. 257 (mm) or less (step S 720
), B5 is determined to be vertical (Step 5721), 2
97 (mm) or less (step 5722), A
It is determined that it is 4 vertical.Steps 5723), 364(
mm) (step 5724), it is determined to be B4 (step 5725), and if it exceeds 364 (mm), it is determined to be A3 (step 9726).

In the second embodiment, the copy number display section is used to display the seven parameters of the special copy, but other numerical display sections such as copy magnification display may also be used.

(Effect of the invention) The present invention enables special copying (binding margin, Anamo bias, etc.)
If an interrupt is made during the process, the special copy parameter value is displayed when the interrupt is canceled and the special copy is returned to. By viewing this display, the user can reconfirm the state before the interruption and prevent copy mistakes.
