Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a jam priority determining processing method that prioritizes each jam and displays the jam screen when a plurality of jams occur. It is.

[Conventional technology]

2. Description of the Related Art In recent years, recording devices such as copying machines and facsimile machines have made remarkable progress in terms of high image quality, multi-functionality, and high reliability, and have become popular in various fields. However, the needs of users are diverse, and it is necessary to meet demands such as high image quality, multifunctionality, and high reliability, as well as low cost, low energy consumption, and high speed. From this point of view, taking a copying machine as an example, the system is divided into multiple subsystems, each subsystem performs the necessary processing, and the main system as a whole manages the processing as a whole. We are working to improve efficiency.

By the way, in conventional copying machines, when a jam such as a document jam or a paper jam occurs, a schematic drawing of the device and the location where the jam should be cleared are displayed all at once on an LED display, so that the user can know where the jam has occurred. I was trying to let you know.

[Problem to be solved by the invention]

However, with the conventional jam display method, if a jam occurs in several locations, the user is confused because he or she does not know where to start clearing the jam. It required a lot of memory space for display.

The present invention is intended to solve the above problems.

A first object of the present invention is to improve operability by making it easier for the user to understand in what order the jams should be cleared when multiple jams occur.

A further object of the present invention is to save jam screens by not displaying jams at all locations at once, and to reduce memory capacity for this purpose.

[Means and effects for solving the problem] The present invention
As shown in the figure, the jam detection means 01, the jam priority determination means 02, and the display means 03 are provided, and the jam display priority determination means prioritizes the jams when a plurality of jams occur. , a jam is displayed according to the priority order.

The jam detection means 01 consists of sensors placed at multiple locations on the input device, the main body, and the output device, and depending on whether these sensors are ON or OFF, it is possible to detect jams with the same jam clearing rate in the same zone. Jams are detected by dividing into a plurality of divided jam zones, and the jams are prioritized by a jam priority determining means 02.

In this case, the order of priority is input device, output device, and main body, and further priority is given within input device, output device, and main body. The priority is determined based on which zone the jam occurred in. In the case of a dynamic jam that occurs while the device is operating, the jam with the highest priority is displayed, and when it is cleared, the next highest priority jam occurs. Jam display is performed in order of priority.

Further, in the case of a static jam detected at the start, the jams are sequentially displayed at predetermined time intervals, for example, at 5 second intervals, starting from the highest priority. Note that the paper position within the main unit is constantly monitored, and if the machine stops due to a hard down in a specific position, such as under the user, the paper will be automatically removed regardless of whether the paper has jammed or not. , to prevent danger by indicating a jam when the device is stopped. Therefore, when multiple jams occur, the user can see at a glance the order in which to clear the jams by looking at the jam screen display, making it easier to clear the jams, and displaying all the jams that have occurred at once. Therefore, the jam display screen can be saved and the memory capacity for this can be reduced.

(1-2) Functions and Features of the System (A) The present invention fully automates the copying process from start to finish while being equipped with a wide variety of functions that meet the needs of users. A major feature of the system is that it can be easily operated by anyone by displaying functions, execution conditions, and other menus on a CRT display.

Its main function is to switch the display screen on the CRT display to display menus for selecting functions, setting execution conditions, etc. in each mode: basic copy, advanced copy, and specialized copy. At the same time, by key input, a cascade of screens can be moved to select and designate functions, and execution condition data can be input.

The functions of the copying machine to which the present invention is applied include the following main functions:
It has automatic functions, additional functions, display functions, diagnostic functions, etc.

As for the main functions, it can be used not only for standard paper sizes of A6 to A2.86 to B3, but also for non-standard paper sizes, and as explained earlier, it has a built-in tray with three functions.

In addition, it is possible to adjust the fixed magnification in 7 stages, arbitrary magnification adjustment in 1% increments, and fine adjustment in 0.15% increments between 99% and 101%. Furthermore, there are a density selection function in 7 fixed levels and photo mode, a duplex function, a left and right binding margin setting function in the range of 1 mm to 16 mm, a pilling function, etc.

Automatic functions include automatic paper selection according to the original size, magnification selection when paper is specified, density control, start when the fuser is ready after power on, and clear and power after a certain period of time after copying is complete. It has functions such as save.

Additional functions include composite copy, interrupt, preheating mode, clearing the set number of sheets, clearing all to auto mode, information explaining the function, P key for using an IC card, maximum lock document return to limit the number of set sheets, etc. Full job recovery IJ- using DADF,
Purge to eject paper other than the jammed area, full-page copy without blemishes, editor to copy or delete parts of the original, job program to call and process jobs one by one, and insert blank sheets one by one between copies. There are mounts for printing, center erasers/frame erasers for books, etc.

The display function uses a CRT display, etc. to provide the operator with information on jams, paper remaining, toner remaining, recovered toner full, user waiting time to warm up, function selection inconsistencies, and machine status. It has functions such as displaying messages.

In addition, as a diagnostic function, initialization of NVRAM, input check, output check, history file such as the number of jams and number of paper feeds, setting of initial values used for marking and process codes around the photosensitive material belt, registration gate on timing. It has functions such as adjusting the settings and setting the configuration.

Furthermore, as an option, MS
L HCF, second development colors (red, blue, edge, brown), editor, etc. can be equipped as appropriate.

(B) Features The entire system of the present invention having the above functions has the following features.

(a) Achievement of power saving A high-speed, high-performance copying machine is realized with 1.5kVA. Therefore, 1.5kVA in each operating mode
We have decided on a control method to achieve this, and also decided on power distribution by function to set target values. In addition, an energy system table is created to determine energy transmission routes, and energy system management and verification are performed.

(b) Cost reduction In addition to making expensive parts in-house, improving technology and standardizing them, we are also working to reduce art material costs by improving the life of art materials from the hardware side and reducing toner consumption.

(c) Improved reliability We aim to reduce component failures and extend their lifespan, clarify the in/out conditions for each parameter, reduce design defects, and
We are aiming to achieve 00kcV nomencinance.

(d) Achievement of high image quality This apparatus uses microcarriers made of ferrite for toner particles to make them finer and develops them using a repulsive magnetic field. The photoreceptor is a high-sensitivity pan-color organic photosensitive material belt formed by applying multiple layers of organic photosensitive material, and a Victorian mode that makes full use of set points allows for midtones to be expressed.

These things will improve generation copy,
By reducing black spots, it achieves unprecedented high image quality.

(E) Improved operability It has a fully automatic mode in which copies are executed in a predetermined mode by pressing the start key just by setting the original and inputting the number of copies, and the screen is divided into basic copy, advanced copy, and specialized copy. including setting the copy mode by
Various mode settings can be selected according to the user's requests. These user interfaces are C
This is done using the RT display and a small number of keys and LEDs placed around it in correspondence with the screen, making mode setting possible with easy-to-read display menus and simple operations. Further, by storing the copy mode, its execution conditions, etc. in advance in a non-volatile memory or an IC card, it is possible to automate certain operations.

(C) Example of differentiation In a copying machine to which the present invention is applied, the functions of the copying machine can be controlled by a program stored in an IC card. Therefore, by changing the program stored in the IC card on a card-by-card basis, it becomes possible to differentiate the use of the copying machine. This will be explained using some easy-to-understand examples.

The first example is when a multi-tenant building is equipped with a copy machine that is shared by multiple companies, or even within a single company or factory, there are copy machines that are shared between different departments. Explain the case. The latter joint use is necessary for budget management, and conventionally, devices such as copy risers have been used to manage usage in each department.

This copying machine is relatively equipped with a base machine 1 shown in FIG. Assume that the copying machine has an advanced system configuration. Among the joint users, DADF 1
Some people or departments may require Sorter 3 or Sorter 19.
There are some departments that do not require any additional equipment.

If multiple large departments or departments with different usage patterns try to decide on the cost burden of copying machines based only on their own copy volumes, large companies or departments that only make low-volume copies will need copying machines equipped with various additional devices. This makes it difficult to coordinate with large departments or departments that want to make advanced use of copying machines.

In such a case, IC cards should be prepared according to the usage pattern of each person or each department, and the person or department who wants advanced functions will have to pay more of the basic costs and have many functions. All you have to do is make it available for use. For example, the owner of the most advanced IC card can set the IC card in the IC card device and operate the copying machine to remove the DADF 13, sorter 19, supply trays (6-1 to 6-3) and The Uplex tray 11 can be used freely, and office efficiency can also be improved. On the other hand, those who do not need to sort copy paper can reduce costs by setting an IC card that lacks a sorting program and using only the catch tray 20.

As a second example, a case will be explained in which a copying business operates a self-copying service shop using an IC card.

A plurality of copying machines are arranged in the store, and an IC card device 22 is attached to each copying machine. The customer requests an IC card according to the type of service, sets it in the copier of his/her choice, and makes a self-service copy. Customers who are unfamiliar with copying machines can request an IC card that is programmed to display operating instructions, and by setting this card, the U112 can display various operating information, ensuring that copying operations can be carried out without error. can.

Whether or not to use DADFl 3 and whether or not to perform multicolor recording can also be determined by the IC card provided.
It is also possible to restrict the types of devices used, making it possible to manage customers according to the price. Furthermore, since the actual status of copying operations, such as the number of copies and the size of the copying paper used, can be recorded on the IC card, billing for fees becomes easier, and detailed services such as discounts on copying fees for regular customers are also possible. .

As a third example, a service using an IC card storing a program for a specific user will be described. For example, in patent offices, when considering patent publications that have been reduced by photolithography, it is necessary to make copies of the original size.
I have a job where I have to make copies at a relatively large enlargement rate of 0.00%. Furthermore, when creating drawings to be submitted to government offices, the original drawings are reduced or enlarged in small increments in order to meet the requests. In addition, departments that make copies of resident records, such as city halls or ward offices, remove information about people who are not eligible for claims and areas that should be kept confidential to protect individual privacy. or create an excerpt.

As described above, some users have a demand for using copying machines in special ways. If the functions of the copying machine were set to satisfy all of these requirements, the console panel would become complicated and the ROM inside the copying machine would become large. Therefore, by preparing an IC card for each specific user and having the IC card set therein, it is possible to realize a copying machine having functions most suitable for that user.

For example, in the case of a patent office, by purchasing a dedicated IC card, it becomes possible to easily select a fixed magnification of 200% in addition to the usual several types of magnification. Furthermore, it becomes possible to set the reduction ratio in steps of, for example, 1% within a range that requires fine adjustment. Furthermore, the department issuing resident records can now use keys such as a numeric keypad to instruct the type of resident record and fields and items to be deleted on a display such as a liquid crystal display, and then press the start button. By pressing this button, only the desired range of the original will be copied, or only the necessary parts will be edited and recorded.

(1-3> Configuration of electrical system control system of copying machine FIG. 3 is a diagram showing the configuration of a subsystem of a copying machine to which the present invention is applied, and FIG. 4 is a diagram showing the hardware configuration using a CPU.

A copying machine system to which the present invention is applied includes an SQMGR subsystem 32 on a main board 31, as shown in FIG.
, C8M subsystem 33.1MM subsystem 34,
Four subsystems consisting of the marking subsystem 35, the surrounding U/I subsystem 36, and the INPUT
Subsystem 37.0UTPUT Subsystem 38, O
It is composed of nine subsystems including five subsystems including a PT subsystem 39 and an IEL subsystem 40. In contrast to the SQMGR subsystem 32, the C8M subsystem 33 and the 1MM subsystem 34 are executed by software under the main CPU 41 shown in FIG. 4 together with the SQMGR subsystem 32, so that the subsystem does not require communication. connected via an interface (shown as a solid line). However, since the other subsystems are executed by software under a CPU separate from the main CPU 41, they are connected through a serial communication interface (indicated by dotted lines). Next, these subsystems will be briefly explained.

The SQMGR subsystem 32 receives the copy mode setting information from the U/I subsystem 36, and assigns work to each subsystem while synchronizing each subsystem so that the copy work can be performed efficiently. It is a sequence manager that issues instructions, constantly monitors the status of each subsystem, and quickly assesses the situation when an abnormality occurs.

The C8M subsystem 33 is a subsystem that controls the paper storage tray, duplex tray, manual feed tray, copy paper feed control, and copy paper purge operation.

The 1MM subsystem 34 is a subsystem that performs panel division on the photosensitive material belt, control of running/stopping of the photosensitive material belt, control of the main motor, and other controls around the photosensitive material belt.

The marking subsystem 35 is a subsystem that controls the corotron, the exposure lamp, the developing machine, the potential of the sensitive material belt, and the toner density.

The U/I subsystem 36 is a subsystem that performs all user interface control, machine status display, job management such as copy mode determination, and job recovery.

The INPUT subsystem 37 is an automatic document feeder (DA).
DF), semi-automatic document feed (SADF), large size (
A2) document feed (LDC), computer form document feed (CFF), automatic 2-sheet document feed <2-UP
) control, repetitive automatic document feeding (RDH) control,
This is a subsystem that detects the document size.

The 0UTPUT subsystem 37 is a subsystem that controls a sorter and a finisher and outputs copies in sorting, scooking, and non-sorting modes, or in a binding manner.

The OPT subsystem 39 is a subsystem that controls scanning, lens movement, shutter, and PIS/N0N-PIS during document exposure, and also performs carriage movement during LDC mode.

The IEL subsystem 40 is a subsystem that erases unnecessary images on the photosensitive material 4, erases the leading edge and trailing edge of the image, and erases images according to the editing mode.

The above system is configured with seven CPUs as shown in FIG. 4 as the core, and can flexibly respond to combinations of the base machine 1 and additional devices surrounding it.

Here, the main CPtJ41 is on the main board of the base machine 1, and the SQMGR subsystem 32, C8M
Subsystem 33.1 includes software of MM subsystem 34, and connects each CPtJ42 to 47 via serial bus 53.
connected to. These CPtJs 42 to 47 have a one-to-one correspondence with each subsystem connected by the serial communication interface shown in FIG. Serial communication is
The main CPIJ 41 and each of the other CPUs 42 to 4 according to a predetermined timing, with 100m5ec as one communication cycle.
7. Therefore, for signals that mechanically require strict timing and cannot match the timing of serial communication, an interrupt port (INT terminal signal) is provided for each CPU, and a hot line separate from the serial bus 53 is used. Interrupts are handled. That is, for example, 64 cpm (A4LEF), 3
If a copy operation is performed at a process speed of 0.09 mm/sec and the control accuracy of the registration gate is set to ±1 mm, a job that cannot be processed in the communication cycle of 100 m5 ec as described above will occur. A hotline is required to guarantee the execution of such jobs.

Therefore, since this copying machine can be equipped with various additional devices, it is also possible to adopt a system configuration corresponding to each of these additional devices for software.

One of the reasons for adopting such a configuration is that if the operation control programs for all these additional devices were to be prepared in the base machine 1, the memory capacity required for this would be enormous. Also, (i
i) If a new additional device is developed in the future or the current additional device is improved, the ROM in the base machine 1 (
This is to make it possible to utilize these additional devices without replacing or expanding the read-only memory.

Therefore, the base machine 1 has a basic storage area for controlling the basic parts of the copying machine and an additional storage area for storing the program loaded from the IC card together with the functional information of the present invention. Additional storage area includes DADF 1
Various programs such as the control program No. 3 and the control program Ur12 are stored. and,
I with the specified additional equipment attached to the base machine 1.
When the C card is set in the IC card device 22, U11
2, the programs necessary for the copying operation are read out and loaded into the additional storage device. This loaded program controls the copying operation in cooperation with the program written in the basic storage area, or has a priority position over this program. The memory used here is non-volatile memory consisting of random access memory backed up by batteries. Of course, IC, card, magnetic card,
Other storage media such as floppy disks can also be used as non-volatile memory. In order to reduce the operational burden on the operator, this copier allows settings such as image density and magnification to be preset, and these preset values are stored in non-volatile memory. ing.

(I-4) Serial Communication Method FIG. 5 is a diagram showing the transfer data structure and transmission timing of serial communication, and FIG. 6 is a time shard showing mutual communication intervals in a single cycle.

In the serial communication performed between the main CPU 41 and each CPU (42 to 47), data amounts as shown in FIG. 5(a) are allocated to each. For example, in the case of 01 in the same figure (a), the transmission data TX from the main CPO 41 is 7 bytes, the reception data RX is 15 bytes, and the next slave, that is, the optical CPU
This shows that the transmission timing 1+ ((C) in the same figure) for 45 is 26m5. According to this example, the total communication amount is 86 bytes, and at a communication speed of 96008 PS, the cycle is about 100 mS. And the data length is
As shown in the figure, it consists of a header, commands, and data. When the transmission and reception using the maximum data length shown in FIG. 6(a) is targeted, the entire communication cycle is as shown in FIG. Here, from the communication speed of 9600 BPS, the time required to send 1 byte is 1.2 mS.
The time from when the slave finishes receiving until it starts transmitting is 1 ms, and as a result, 100 m5 is one communication cycle.

(It-1) Optical system FIG. 7(a) is a schematic side view of the optical system of the copying machine, and FIG.
) is a plan view, and the same figure (c) is a side view in the XX direction of figure (b). The scanning exposure device 3 of this embodiment moves the second scanning system B in the opposite direction when the first scanning system A scans the document, and moves the image onto the photosensitive material at a speed faster than the moving speed of the photosensitive material 4. The second scanning system B is fixed and the first scanning system 8 is movable independently.

In FIG. 7(a), the first scanning system A includes an exposure lamp 1
02 and a first carriage 1 with a first mirror 103
01, and a second carriage 105 having a second mirror 106 and a third mirror 107, and scans an original placed on a platen glass 2.

A lens 108 is arranged on the optical axis between the mirror 107 and the fourth mirror 110, and is moved by a lens motor according to the magnification, but is fixed during scanning exposure.

These first scanning system A and second scanning system B are driven by a carriage motor 114 which is a DC servo motor. Transmission shafts 116 and 117 are arranged on both sides of the output shaft 115 of the carriage motor 114, and timing is transmitted between the timing pulley 1!5a fixed to the output shaft 115 and the timing pulleys 116a and 117a fixed to the transmission shaft 116.117. bells) 119a and 119b are stretched.

Further, a capstan pulley 116b is fixed to the transmission shaft 116, and a driven roller 120 is disposed opposite to the capstan pulley 116b.

The first carriage 101 is fixed to the wire cable 121a, and the wire cable 121a is connected to a deceleration boot provided on the second carriage 105. When the carriage motor 114 is rotated in the direction of the arrow shown in the figure, the first carriage 101 moves in the direction of the arrow shown in the figure at a speed Vl, and the second carriage 105 moves at a speed V, /2.
so that they move in the same direction.

In addition, the timing boot IJ fixed to the transmission shaft 117
l 17 b and the transmission shaft 123 arranged opposite thereto.
Between the timing pulley 123a of the timing bell)
119c is stretched, and the capstan pulley 123b of the transmission shaft 123 and the driven roller 12 disposed opposite thereto.
A second wire cable 121b is stretched between the oc. The fourth carriage 112 is fixed to the wire cable 121b, and the wire cable 1

25 (electromagnetic clutch) is provided, and when the PIS clutch 125 is de-energized, it is engaged and the rotation of the rotating shaft l15 is transmitted to the transmission shafts 117 and 123.

Further, when the PIS clutch 125 is energized and released, the rotation of the rotary shaft 115 is not transmitted to the transmission shafts 117 and 123.

Also, as shown in FIG. 7(C), timing boo! 1
An engaging protrusion 126a is provided on the side surface of the L
When the DC lock solenoid 127 is turned on, the engagement piece 126
b engages with the engagement protrusion 126a to fix the transmission shaft 116, that is, fix the first scanning system A, and turn on the LDC lock switch 129. Plus, timing boo! An engagement protrusion 130a is provided on the side surface of J123a, and when the PIS lock solenoid 131 is turned on, an engagement piece 130b engages with the engagement protrusion 130a to fix the transmission shaft 123, that is, fix the second scanning system B. Then, the PIS lock switch 132 is turned on.

In the scanning exposure apparatus configured as described above, the PIS (Preset Imaging System) mode and N0N-PIS are switched by disengaging and disengaging the PIS clutch 125.
The exposure method of the mode is selected. In the PIS mode, for example, when the magnification is 65% or more, the PIS clutch 125 is engaged and the second scanning system B is moved at a speed of 2, thereby changing the exposure point of the photosensitive material belt 4 in the opposite direction to the photosensitive material belt 4. The scanning speed V1 of the optical system is made relatively faster than the process speed V, thereby increasing the number of copies per unit time.

At this time, if the magnification is M, then V+ = Vp X 3゜5
/(3,5M-1>, M=1, V,=308.9
If it is mm/s, then V+ = 432.5 mm/S.

Moreover, (2) is determined by the diameters of the timing pulleys 117b and 123a, and is v2=N/3 to 1/4)V. On the other hand, in the N0N-P■S mode, for example, 6
If it is less than 4%, the PIS clutch 125 is released and the PIS lock solenoid is turned on to fix the second scanning system B and scan with the exposure point fixed. This is because, in the PIS method, the speed of the scanning system increases and the illumination power must also be increased during reduction, and an increase in the load on the drive system and the illumination power is avoided.

The lens 108 is mounted on a lens carriage 13 disposed below the platen glass 2, as shown in FIG. 8(a).
It is slidably attached to a support shaft 136 fixed to 5. The lens 108 is connected to a lens motor Z137 by a wire (not shown), and the lens motor Z
The rotation of 137 moves the lens 108 along the support shaft 136 in the Z direction (vertical direction in the figure) to change the magnification.

The small gear 142 provided at the lens cam 143 rotates along the cloud-shaped surface of the lens cam 143, which causes the large gear 144 to rotate and move the mounting base 146 of the second scanning system via the wire cable 145.

Therefore, the rotation of the lens motor X140 causes the lens 10 to
8 and the second scanning system B can be set for a predetermined magnification.

Further, as shown in FIG. 8(b), a lens shutter 147 is provided on one side of the lens 108 so that it can be opened and closed by a link mechanism 148, and the lens shutter 147 is turned on and off during image scanning by turning on and off a shutter solenoid 149.
7 is open, and when the image scan is completed, it is closed. The reason why the lens shutter 147 is closed to block the optical path except during image scanning is as follows.
Forming a patch; ■In PIS mode, the second scanning system B returns to catch up with the latent image formed on the belt photosensitive material to prevent image stagnation; ■Feeling when the platen cover is opened The purpose is to prevent fatigue of the material due to external light.

FIG. 9 shows a block configuration diagram showing an overview of the subsystem of the optical system. As mentioned earlier, optical C
The PU 45 is connected to the main CPU 41 through serial communication and a hotline, and controls each carriage, lens, etc. in order to form a latent image on the photosensitive material according to the copy mode transmitted from the main CPU 41. The control power supply 152 is for logic (5V), analog (±15V), solenoid, and clutch (24V).
The motor power supply 153 is composed of 38V.

The carriage registration sensor 155 is connected to the first carriage 101.
When the first carriage 101 reaches the document registration position, the actuator 154 provided on the first carriage 101 is placed in a position where it does not step on the carriage registration sensor 155, and the actuator attached to the first scanning system 8 moves the carriage registration sensor 155.
If you miss step 5, a signal will be output. This signal is sent to the optical CPU 45 and serves as a reference for determining the position or timing for performing registration, and for determining the home position P when the first scanning system A returns. Also, a first home sensor 156a for detecting the position of the carriage.

A second home sensor 156b is provided, and the first home sensor 156a is arranged at a predetermined position between the registration position and the stop position for the first scanning system, and detects the position of the first scanning system A and sends a signal. is outputting.

Further, the second home sensor 156b detects the position of the second scanning system and outputs a signal.

The rotary encoder 157 is connected to the carriage motor 114
This is a type that outputs A-phase and B-phase pulse signals with a 90° phase shift depending on the rotation angle of the
The axial pitch of the timing pulley of the first scanning system is designed to be 0.1571 mm/pulse in terms of pulse/rotation.

The biasing solenoid 159 moves a biasing lens (not shown) in the vertical direction under the control of the CPU 45, and is turned on by turning on a biasing switch 161 fixed in the optical path. The lens home sensor 161.162 is connected to the lens 10.
This is a sensor for detecting the home position of 8 in the X direction and the Z direction, and is arranged on the reduction side with a predetermined interval from the position at the same magnification.

The LDC rotary solenoid 127 fixes the first scanning system 8 at a predetermined position under the control of the CPU 45.
Confirmed by turning on operation of 29.

The PIS lock solenoid 131 locks the second lock solenoid when the PIS clutch 125 is released in the N0N-PIs mode.
The scanning system B is fixed, and locking of the second scanning system is confirmed by turning on the PIS lock switch 132.

The PIS clutch 125 is of a type that releases the clutch when energized and engages the clutch when not energized.
Reduces power consumption in S mode.

Next, control of the scan cycle of the optical system will be explained with reference to FIGS. 1θ (a) and (b). FIG. 1O(a) shows the relationship between the speed of the carriage motor 114 and time.

This control is to scan the first scanning system 8 at a designated magnification and scan length, and is activated when a scan start signal is received from the hotline. An image scan count, which is the count of the encoder crotter from the registration sensor interrupt to the end of the scan, is calculated from the scan length data received from the main unit.

First, after setting the reference tally data corresponding to the magnification, the carriage motor is rotated in the scanning direction (CW) in step
), and in the speed mode, the DAC data is set every time an encoder pulse interrupts to perform acceleration control during scanning (step 2). Next, in step (2), the PLL (phase control) mode is set, and if there is an interrupt signal indicating that the register sensor is off in step (2), the process proceeds to step (3), and here, when the count number of the encoder cross is above the amount corresponding to the above scan length. , cancel the PLL mode, set the speed mode, and apply reverse driving force to the carriage motor to decelerate it.

Next, in step 2, it is determined whether or not there is an interrupt from CW to CCW (reverse rotation signal), and if so, acceleration control is performed at the time of return in the speed mode (step 2).
), when the encoder count reaches the preset brake start point (step [phase]), deceleration control is performed at the time of return, and when the registration sensor is depressed, a scan end signal (high level) is sent to the main CPU ( step o
), if there is a reverse rotation signal again, stop the carriage motor (step ■). In addition, in the CPU, ■, ■, ■, ■, ■
Set the counter that counts the encoder clock to 0 at the point
is being reset to.

Further, FIG. 10(b) shows the opening/closing control of the shutter 147. Since there is a time lag between the on/off of the shutter solenoid and the fully open/closed state of the shutter, the shutter is controlled so that the solenoid is turned on just before the shutter passes the registration sensor, and the solenoid is turned off just before the end of the scan. First, the number of counts from the scan start until the shutter is turned on (opened) is called the shutter on count, and then the image scan count and the number of counts from the shutter off (closed) to the end of the scan (shutter off count). Calculate the difference between. These shutter-on count and shutter-off count data are prepared in the ROM as a table. According to this method, since the scan count number is calculated from paper size data, there is no need to have a table of shutter-on counts and shutter-off counts for each paper size.

Next, image scanning is started, and when the encoder tallock number exceeds the shutter-on count, the shutter is opened, and if there is a register-off interrupt, the encoder clock number and shutter-off count are compared, and the encoder clock number is determined. When the shutter off count is exceeded, the shutter is closed and the image scan is completed.

(n-2) User interface (U/I) (II-
2-1) Features of User Interface FIG. 11 is a diagram showing how the user interface using the display is installed, and FIG. 12 is a diagram showing the appearance of the user interface using the display.

Conventional user interfaces are mainly console panels equipped with keys, LEDs, and liquid crystal displays, such as back-lift types and those with message displays. A backlift type console panel is a display board on which a fixed message has been placed at a predetermined position, and is selectively illuminated from behind with a lamp or the like to make that part readable. The console panel is composed of, for example, a liquid crystal display element, and is designed to display various messages at any time without increasing the display area.

Which of these console panels to adopt is determined for each copying machine, taking into consideration the complexity of the system configuration and operability of the copying machine.

(A) Features of mounting position The present invention is characterized in that a stand-type display is used as the user interface, rather than using the conventional console panel as described above. If a display is adopted, it can be mounted three-dimensionally above the copying machine main body (base machine) l as shown in FIG. Machine body l
By arranging it in the back right corner of the printer, the size of the copying machine can be designed without considering the user interface 12, and the apparatus can be made more compact.

Further, in a copying machine, the height of the platen, that is, the height of the device, is designed to be a comfortable height for setting a document, and this height regulates the height of the device. As mentioned earlier, conventional console panels are mounted on the top surface at this height, and the operating and display sections for selecting functions and setting execution conditions are placed at a fairly comfortable distance from the eyes. . In this regard, the user interface 12 of the present invention is located at a higher position than the platen, that is, close to eye level, as shown in FIG. Moreover, it is on the right side, making it easier to operate. Moreover, by bringing the height of the display closer to eye level, the lower side can be effectively used as a space for mounting the user interface control board and card device 24. Therefore, there is no need to make structural changes to attach the card device 24, and the card device 24 can be additionally equipped without changing the appearance at all, and at the same time, the display can be attached in a position and height that is easy to see. Furthermore, although the display may be fixed at a predetermined angle, it is of course possible to change the angle. Unlike conventional console panels that are mounted flat on the front side of the platen, the front direction of the console panel can be easily changed, so the display screen can be easily moved to the operator's side, as shown in Figure 11 (C). Slightly upward to match the line of sight and Figure 11 (b)
As shown in FIG. 2, by pointing to the left, that is, toward the upper center (direction of the operator's eyes), it is possible to provide a user interface 12 that is easier to see and easier to operate. By employing such a configuration, especially in a compact device, an operator can operate the document set and the user interface without moving from the center of the device.

(B) Characteristics on the screen On the other hand, even when using a display, the amount of information needed to provide information corresponding to multi-functions increases, so if you think about it simply, a large display area is required, making it more compact. This has the aspect that it becomes difficult to respond to the situation. By adopting a compact size display, providing all the necessary information on one screen is not only a matter of display density, but also makes it easier for the operator to see.
It is also difficult to provide an easy-to-understand screen. Therefore, we have taken various measures to display the information in an easy-to-understand manner even though it is compact in size.

For example, in the user interface of the present invention, the display screen is switched according to the copy mode, and menus for selecting functions and setting execution conditions are displayed in each mode, and the screen cascade (cursor) and You can specify options and enter execution condition data by moving the . In addition, depending on the menu option, detailed items are displayed in a pop-up (superimposed display or window display) to expand the displayed content. As a result, even if there are many selectable functions and setting conditions, the display screen can be kept clean and the operability can be improved. In this way, the present invention has devised techniques for screen division, area division on each screen, brightness adjustment, gray display, and other display modes, and furthermore,
By skillfully combining D, the operation section can be simplified, the display control, display contents, and operation input can be diversified and simplified, and the problem of making the device more compact and multifunctional can be solved. ing.

FIG. 12 shows the appearance of a user interface constructed using a CRT display. In this example, keys/LED boards are arranged below and in front of the CRT display 301 on the right side. In the selection mode screen, the screen is divided into multiple areas QIL 1.
A selection area is provided as one area, and the selection area is further divided vertically so that each can be selected and set as a cascade area. Therefore, on the key/LED board, cascade keys 319-1 to 319-5 for cascade selection settings are placed below the selection area of the vertically divided screen, and mode selection keys 319-1 to 319-5 are used to switch the selection mode screen. 308-310 Other keys (302-304.306
．． 307.315-318) and LEDs (305,31
1 to 314) are arranged on the right side.

(n-2-2) The display screen configuration screens include a selection mode screen for selecting the copy mode, a review screen for checking the copy mode setting status, and a full screen for copying in standard mode. It consists of an automatic screen, an information screen that provides explanations about the multifunctional copy mode, and a jam screen that appropriately displays the location of a jam when it occurs.

(A> Selection mode screen FIG. 13 is a diagram for explaining the selection mode screen.

As the selection mode screen, three screens are set as shown in FIGS. 13(a) to 13(C): basic copy, advanced copy, and specialized copy.
The display will be switched to the RT display. Of these screens, the basic copy screen categorizes and groups the most commonly used functions, and the advanced copy screen categorizes and groups the next most commonly used functions. The specialized copy screen is a grouping of special specialized functions.

Each selection mode screen basically consists of a message area A consisting of two lines from the top, a setting status display area B consisting of three lines,
It is used by dividing it into a selection area C consisting of nine lines. Message area A displays J-code messages when there is a conflict in the copy execution conditions, J-code messages when there is a hardware failure that requires contacting a service person, and C-code messages that call for various precautions to the operator. be done.

Among these, the J code message is equipped with a check table for combinations of copy execution conditions based on the settings of each cascade, and when the start key 318 is operated, the table is checked by referring to the table and output if there is a conflict in the copy mode. be done. The setting status display area B displays the selection status of other modes, for example, the selection status of advanced copy and specialized copy with respect to the basic copy screen. In this selection state display, if the cascade state of the selection area C is other than the default (lower row), the cascade is displayed. In selection area C, cascade salt is displayed in the upper row,
The lowest level of each cascade area is a default area, and the area above it is a non-default area, and each of the five cascade areas can be selected individually by operating a cascade key. Therefore, if no selection operation is made, the default area is selected and all default settings are set to full automatic copy mode. Further, the selection area is selected and set using lower cascade keys 319-1 to 319-5 corresponding to cascade areas divided vertically into five areas. In addition, the right side to the message area serves as a count section that displays the set count and maid count.
Further, the bottom line of the setting status display type FaB is used as a maintenance information section such as toner bottle full, toner replenishment, etc.

The contents of the cascade area of each selection mode screen will be explained below.

(B) Basic copy The basic copy screen consists of a cascade of "paper tray", "reduction/enlargement", "duplex copy", "copy density", and "sorter" as shown in FIG. 13(a).

For "Paper Tray", automatic is the default,
In this case, a tray containing paper of the same size as the original is automatically selected. By operating the cascade key, you can use areas other than the default to select the manual feed tray, large capacity tray, upper tray, middle tray, or lower tray.

Note that in the column of each tray, the paper size, type, and icon (pictogram) are displayed to make it easy to identify the paper stored therein, as shown in the figure. Paper can be set to be fed in the longitudinal direction or in a direction perpendicular to the longitudinal direction.

The default for "reduction/enlargement" is the same size, and automatic, fixed/arbitrary can be selected by operating the cascade key. Automatically sets the magnification according to the selected paper size and copies. The magnification (linear magnification) is
It can be set arbitrarily in 1% increments from 50% to 200%, and when fixed/arbitrary, the specific setting target will be displayed on a pop-up screen by operating the cascade key, 50.7%, 70%. , 81%, 100%, 1
It is possible to select a fixed magnification consisting of seven settings of 21%, 141%, and 200%, and it is also possible to select and set an arbitrary magnification that continuously changes in 1% increments.

For "double-sided copy," one-sided is the default, and in addition to the default, you can select from two-sided to one-sided, two-sided to two-sided, and one-sided to two-sided in the relationship of original to copy. For example, double-sided→single-sided is a one-sided copy of a double-sided original, and one-sided→double-sided is a double-sided copy of a one-sided original. When making double-sided copies, the copy paper on which the first side has been copied is first stored in the duplex tray. The copy paper is then fed out again from this duplex tray and a copy is made on the back side.

"Copy Density" is set to automatic by default, and there are seven density settings other than the default, and seven density settings can be made in the photo mode as well. Setting of this content is done using a pop-up screen.

The default for "sorter" is copy receiving, and collation and stacking can be selected as non-default options. Collate mode is a mode in which copy sheets are sorted into each bin of the sorter, and stack mode is a mode in which copy sheets are stacked in order.

(b) Advanced copy The advanced copy screen consists of a cascade of "special original", "binding margin", "color", "interleaf sheet", and "ejection side" as shown in FIG. 13, etc.

"Special originals" include the function to copy large originals such as A2/83 (LDC), and the function to count holes and copy page by page from computer continuous output originals (CFF).
, computer form feeder), double copy function (2-UP) that copies two sheets of the same size onto one sheet of paper
) can be selected other than the default.

The "binding margin" is 1mm at the right or left edge of the copy.
The "binding margin" is set in the range of ~16 mm, and it is possible to set right binding, left binding, and binding margin lengths other than the default.

"Color" defaults to black, and you can select red other than the default.

"Paper" is a function that inserts a blank sheet in the middle during OHP copying, and can be selected other than the default.

"Ejecting side" can be selected other than default so that either the front side or the back side can be forcefully specified to eject the paper.

(C) Specialized Copy The specialized copy screen consists of a cascade of "Job Memory", "Edit/Composition", "Same Size Fine Adjustment", and "Erase Frame", as shown in FIG. 13(C).

"Job Memory" is a page program that uses a card, and allows you to register multiple jobs and automatically copy them by recalling them and pressing the start key. Call and registration can be selected other than the default.

"Edit/Composition" allows you to select an editing function and a composition function other than the default. The editing function is a function for inputting data for editing using an editor etc. In addition, the pop-up screen allows you to input partial color, partial photo, etc.
Partial deletion and marking color functions can be selected. For partial color, only the specified area is copied in one color, and the rest is copied in black. Partial photos are
Copy the photo to the specified area, and partial deletion will prevent the specified area from being copied. The marking color is
When an area to be marked is specified, for example, a light color is recorded over that area to create an effect as if marking has been performed.

The compositing function is a function that uses a duplex tray to make one copy from two originals, and includes sheet compositing and parallel compositing. Sheet composition is a function that records both the first document and the second document in their entirety on one sheet of paper.
It is also possible to copy the first original and the second original in different colors. On the other hand, parallel composition combines the entirety of the second manuscript into the entirety of the first manuscript.
This function creates a composite copy on a single sheet of paper.

"Same magnification fine adjustment" is 0.15 at a magnification of 99% to 101%.
It is set in % increments, and you can select this function other than the default.

"Frame erase" does not copy the image information on the periphery of the document, but makes it appear as if a "frame" has been set around the image information, and the default is to erase the border at 2.5 mm. You can set arbitrary dimensions and select a full copy mode without border erasing other than the default.

(B) Other Screens FIG. 14 is a diagram showing an example of a screen other than the selection mode screen.

(B) Review screen The review screen is for displaying the status of the copy mode selected on each of the above selection mode screens divided into three, and as shown in Figure 14 et al. The setting status of the cascade is displayed on one screen. This review screen displays the selected item, i.e., the cascade name, and the currently selected mode, i.e., the option. If the selected mode is the default, for example, the background will be faded, and if it is other than the default, the background will be normal brightness. It uses an inverted display.

(b) Fully automatic screen The fully automatic screen is the screen shown in Fig. 14(a) when the power is turned on, when the preheating key 306 is operated in preheating mode, or when the all clear key 316 is operated. When displayed. This screen shows a state where all the cascades of each selection mode screen are set to default. On this screen, when the original is set on the platen as instructed, the number of copies is set using the numeric keys, and the start key 318 is pressed, paper of the same size as the original is selected and the set number of copies are executed.

(c) Information screen The information screen is a screen for providing an explanation screen on how to make copies, etc. for each of the copy modes shown in FIG. 14(C), and is displayed by operating the information key 302. An explanation screen is displayed by inputting the information code displayed on the screen using the numeric keypad.

(d) Jam screen The jam screen is displayed over the screen that was displayed during copying, as shown in Figure 14(d), and is displayed by lowering the brightness of the original screen one rank at a time. I try to make the content clear.

(C) Display Mode The present invention can display images by dividing the screen into a plurality of screens and switching between them as explained in FIGS. 13 and 14.
By reducing redundant information at any given time, simplifying the information on one screen, and changing the display mode according to the display area of these layouts and the state of input settings, etc., a screen with accents that is easy to see and understand is created. . For example, the selection mode screen is divided into a message area '5A (including the count area), a setting status display area (including the maintenance information area), and a selection area, as described above, and the display mode of each area is is changing. For example, in the message area containing Callan)l, the background is black and only the message string is displayed with high brightness, similar to the appearance of a bat-lid type console panel. Further, in the setting state display area, the background is displayed as a mesh, that is, the background is displayed in brightness and darkness with a predetermined uniform density of dots, and the display portion of the cascade salt is displayed in reverse (the characters are displayed dark and the background is displayed brightly). That is, this display represents each cascade salt as a card image. Furthermore, the bottom line of the setting status display area is used as a maintenance information area such as when the toner bottle is full or toner replenishment, but this information is different in nature from the setting status display information, so the difference is clearly visible. In order to be able to recognize
The display format is similar to that of the message area.

In the selection area, the surrounding area is displayed as a mesh, and the entire cascade display area is displayed in gray with low brightness, and the options and cascade salts are displayed in reverse.

In addition to this display, the background of the set option area is displayed in high brightness (inverted display), and for example, on the basic copy screen, the background of the tray that has run out of paper in the cascade of paper trays is displayed in black. The characters are displayed with high brightness.

In addition, on the fully automatic screen shown in Figure 14(a), the background of the display area is displayed with a dark mesh, and the area where each operation instruction such as "Set Original" is displayed with a bright mesh, and the border is bordered. This improves the clarity of the display and makes it easier to read. It goes without saying that the display mode of the background can be freely changed and combined as desired.

In particular, regarding the boundaries of areas such as displaying the background with high brightness (normal brightness with paper white), gray gradation display with reduced brightness, and display with a predetermined brightness and darkness dot density,
The border as shown gives a visual three-dimensional effect and gives the image of a card. In this way, by performing border display while changing the display mode of the background of each area, the operator can clearly distinguish the display contents of each area, providing an easy-to-read screen. Furthermore, when displaying characters, by displaying them in reverse or blinking, it is possible to draw the user's attention to each piece of displayed information.

Furthermore, in addition to devising the background in a character string and changes in the brightness of the characters as described above, the present invention also adds icons (pictograms) to options, cascade salts, and other character strings to make them more imaginative. It is also distinctive in that it uses a distinctive display mode. For example, on the basic copy screen, the cascade salts "Reduce/Enlarge", "Double-sided copy", "
These are the ones added at the beginning of "copy density" and "sorter," and the ones added after the lower, middle, and upper paper sizes in the "paper tray" option. This icon conveys information visually to the user from a different perspective, that is, the accent of information is weakened by text strings alone, and depending on the content of the information, it is necessary to be more accurate and intuitive than text strings. It has a great advantage in that it can convey information to users.

([-2-3) The key/LED board user interface is as shown in Figure 12.
Although it is composed of a T-display and a key/LED board, the present invention is configured to use the CRT display screen to display options and set them, so the keys and LEDs on the key/LED board are Efforts are being made to keep the number to a minimum.

Mode selection keys 308 to 310 for screen switching and cascade key 31 for selecting each cascade area
Functions can be selected and set using eight keys numbered 9-1 to 319-5.

Therefore, if you operate the mode selection keys 308 to 310 to select the basic copy screen, advanced copy screen, or specialized copy screen, then the cascade keys 319-1 to
All functions can be selected by simply inputting numerical values using the numeric keypad 307 other than the operation of 319-5, and copying can be executed using the desired function. Cascade key 319-1~
319-5 is a pair of upward movement key and downward movement key in order to select and set a function by moving the setting cursor up and down in each cascade area. In this way, the selection mode screen is selected from among the three mode selection keys 308 to 310 and only one of them is displayed.
The LEDs 311 to 313 are used to indicate whether the item is selected by 08 to 310. That is, when the mode selection keys 308 to 310 are operated to display the selection mode screen, the LEDs 311 to 313 corresponding to the mode selection keys 308 to 310 are lit.

When a computer has many functions, it becomes difficult for the user to remember and use all of the functions. Therefore, the information key 302 is used to provide a screen explaining how to make a copy for each copy mode. This information function is executed as follows. First, information key 30
When 2 is operated, a list of information codes is displayed on an information index screen as shown in FIG. 14(C). When the specified information code is selected and inputted on this screen using the numeric keypad 307, the screen moves to an information pop-up screen corresponding to that code, and an explanation screen for the copy mode is displayed there.

In addition, as shown above, the selection mode screen is divided into three, and selection settings for various functions defined on the three screens are performed, so you can check the overall setting status including other screens. You are also required to do so. Therefore, the review key 303 is used to check the setting state of such a full screen.

The dual language key 304 is a key for switching the language of the display screen. With internationalization, devices are often shared by users who use various different languages. Even in such an environment, in order to eliminate language barriers, for example, display data and font memory can be prepared in two languages, Japanese and English, and the display data and font memory can be switched by operating the dual language key 304. To output a display screen by freely switching between Japanese and English. Note that it is also possible to provide not only two languages but also a plurality of languages, and to switch between languages in a predetermined order by operating the dual language key 304.

The preheating key 306 is used to set the preheating mode in order to save power consumption by indulging in the non-use state and to enable a quick transition from the non-use state to the copy operation. and fully automatic mode. Therefore, the LED 305 is used to indicate which state it is in.

The all clear key 316 is used to clear the copying machine, that is, to set it to the fully automatic mode set as the default for each selection mode screen, and displays the fully automatic screen. This is the content of the screen that informs the operator that the current copy mode is fully automatic, as shown in FIG. 14(a).

The interrupt key 315 is a key used when continuous copying is in progress and it is necessary to make another emergency copy, and when the interrupt processing is completed, it is used to return to the original copying operation. will also be canceled. LED3
14 indicates whether this interrupt key 315 is in an interrupt state or a released state.

The stop key 317 is used to stop the copying process, to set the number of copies, and to set the sorter bin.

The start key 318 is operated when the function selection and its execution conditions are completed and the copying operation is started.

A key/LED scan time of 4.98 m5 is created by inputting a MHz clock and further dividing the frequency by 1/27 to 102 kHz using a prescaler.

If this scan time is not too long, it will take a long time to detect the input, which will cause the problem that input data will not be captured when the key operation time by the operator is short.On the other hand, if it is too short, the CPU operation frequency will increase. This will result in a decrease in throughput. Therefore, it is necessary to select the optimal scan time taking these situations into consideration.

(B) Software configuration The software configuration of the user interface is
As shown in the figure, there is a monitor with I10 management, task management, and communication protocol functions, a video controller with key input management and screen output management functions, and functions such as job management, control, selection judgment, mode determination, etc. It consists of a job controller with a And for key input, the video controller processes the physical information of the key,
The job controller recognizes the mode, checks acceptance conditions, and controls the job. For screen display, the job controller controls the screen based on machine status information, selection mode information, etc. and issues interface commands to the video controller, which then executes the commands and edits and draws the screen. Note that the key change detection unit 362 described below
, and other blocks that process, generate, and control data are each shown as a certain program unit (module), and these structural units are grouped together for convenience of explanation, and some are Of course, the inside may be constructed from a plurality of modules, or a plurality of modules may be constructed all at once.

In the video controller, the key change detection section 362 performs a double press check or continuous key press state detection on the physical key information passed from the monitor using the physical key table 361. The key conversion unit 363 converts the currently pressed physical key detected in this way into a logical key (logical information), and checks the key acceptance condition of the logical key (current key) in a job. Request to controller. The conversion table 364 is used by the key conversion unit 363 when converting this physical key into a logical key.
For example, even if the cascade key is the same physical key, the logical information differs depending on the screen, so the conversion from the physical key to the logical key is controlled by the display screen information of the display control data 367.

The screen switching section 368 receives a key acceptance signal and a logical key from the job controller, or directly receives a logical key from the key converting section 363 within the video controller, and displays whether the logical key calls a basic copy screen or an advanced copy screen, or a cascade screen. If it is a simple screen switching key that opens a pop-up screen by moving the key, and the key does not update the mode or state, the display control data 367
The display screen number is updated to the corresponding screen number. Therefore, the screen switching unit 368 stores the logical keys for expanding the pop-up screen as a table, and when the logical key is operated and there is no other key input within 750 msec, the pop-up screen is expanded. The display control data 367 is updated. This process is used to prevent the pop-up screen from being expanded all at once in some cases where the option to temporarily expand the pop-up screen is selected by operating the cascade key during the selection process of a certain option. It is something that is done on a regular basis.

Therefore, even if there is a logical key that opens a pop-up screen, if there is another key input within 75C1 msec, it will be ignored as a temporary key input. In addition, in the case of updating the state such as the occurrence of a jam, updating the copy mode such as moving cascade, or updating the message or count value, the display control unit 369 receives an interface command from the job controller and analyzes it.
Display control data 3670 is updated.

The display control data 367 has data for controlling the display of each screen, such as the screen number to be displayed and display variable information within the screen, and the dialog data 370 has the basic frame of each screen,
It is a hierarchically structured database having display data of each frame and reference addresses of variable data among the display data (addresses of display control data 367 storing display variable information).

The dialog editing unit 366 creates a basic frame of the screen to be displayed based on the screen number to be displayed in the display control data 367;
The display data is read from the dialog data 370, and the display data is determined according to the display variable information of the display control data 367, and the screen is edited.
- Render and develop the display screen in the RAM 365.

In the job controller, the key management unit 14 refers to the state table 371 and checks whether the logical key is in a state where it can be accepted. On the condition that no key information is input, the key information is determined and sent to the key control section 375. Key control section 375
performs key acceptance processing, updates the copy mode 378, issues mode check and copy execution commands,
Display control is performed by grasping the machine state and passing display control information to the display management section 377. Copy setting information for basic copy, advanced copy, and specialized copy is set in the copy mode 378. Display management section 377
issues an interface command to the video controller based on the processing result by the key management section 14 or the key control section 375, and starts an interface routine (display control section 369). Job control section 3
Reference numeral 76 is for managing to execute a copying operation for one document by receiving machine operation information after operating the start key and issuing a command for controlling the machine. The command control unit 373 notifies the state management unit 372 and job control unit 376 of the status of the received command sent from the main body, and also receives commands for execution from the job control unit 376 during job execution. Send to.

Therefore, when the start key is operated and the key control unit 375 sets a command corresponding to the copy mode in the transmission buffer 380 to execute a copy operation, commands indicating the operating status of the machine are sequentially received in the reception buffer 379. Ru.

By notifying the job control unit 376 of this command from the command control unit 373, the next copy execution command is issued each time copying is completed one by one until a predetermined number of copies have been completed and a command to stop the machine is issued. will be issued. During a copy operation, when a jam occurrence command is received, the state management section 372 recognizes the jam state through the command control section 373, updates the state table 371, and at the same time updates the state table 371 through the display management section 377 through the key control section 375.
issues jam screen control interface commands to the video controller.

(II-3) Paper conveyance system In FIG. 17, the upper tray 6-1 serves as a paper tray.
1 A middle tray 6-2, a lower tray 6-3, and a duplex tray 11 are installed in the base machine, and a large capacity tray (HCF) 17 is installed on the side as an option.
, a manual feed tray (MSI) 16, and each tray is equipped with a no paper sensor, a size sensor, a clutch, etc. as appropriate. Here, the no paper sensor is a sensor for detecting the presence or absence of copy paper in the supply tray, and the size sensor is a sensor for determining the size of the copy paper stored in the tray. Further, the clutch is a component for controlling on/off the drive of each paper feed roll. By allowing copy paper of the same size to be set in multiple supply trays in this way, when one supply tray runs out of copy paper, copy paper of the same size can be automatically fed from the other supply trays. .

The copy paper is fed by a specially provided feed motor, and a step motor is used as the feed motor. A feed sensor detects whether copy paper is being fed normally. A gate solenoid is used for registration to align the leading edge of the copy paper once it has been sent out.

This gate solenoid is different from ordinary solenoids of this type in that it controls the gate to open when energized and allow copy paper to pass through. Therefore, in a standby state where copy paper does not arrive, no power is supplied to the gate solenoid, and the gate remains open to reduce power consumption. Then, just before the copy paper arrives, the gate solenoid is energized and the gate closes to prevent it from passing through. Thereafter, when conveyance of the copy paper is resumed at a predetermined timing, the energization is stopped and the gate is opened. By performing such control, there will be less fluctuation in the gate position when the leading edge of the copy paper is blocked from passing, and even if the copy paper is pressed against the gate with a relatively strong force, its position will be maintained. Can be done accurately.

When copying is performed again using a duplex mode in which copies are made on both sides of a sheet of paper or a composite mode in which copies are made multiple times on the same side, the sheets are guided to a conveyance path where they are stacked on a duplex tray 11. In the duplex mode, the photos are directly stacked from the transport path to the duplex tray 11, but in the composite mode, they are first transported from the photographic transport path to the composite mode inverter 10, and then reversed and stacked on the duplex tray 11. Tray 1
It will lead you to 1. Note that a gate 503 is provided at the branch point between the paper discharge outlet 502 from the conveyance path 501 to a sorter, etc. and the duplex tray 11 side, and a gate 503 is provided at the branch point leading to the inverter 10 for composite mode on the duplex tray 11 side. is the gate 505 for switching the conveyance path.
506 is provided, and furthermore, the paper discharge outlet 502 is connected to the gate 5
07 is provided, and by inverting the paper with a tri-roll inverter 9, the paper can be discharged with the copied side facing up.

The upper tray and middle tray hold approximately 500 sheets of paper, A3-B5, legal, letter, and special B4.11X17.
This tray can accommodate paper sizes of . And the first
As shown in FIG. 8, it has a tray motor 551, and has a structure in which a tray 552 tilts when the number of sheets decreases. The sensors include three paper size sensors 553 to 555 that detect the paper size, a no paper sensor 556 that detects paper out, and a surf ace control sensor 557 that is used to adjust the tray height. Also,
There is an emergency switch 558 to prevent the tray from rising too high. The number of sheets of paper in the lower tray is 11.
This tray can store approximately 1,000 sheets of paper of the same size as the upper and middle trays.

In FIG. 17, the duplex tray is a tray that can accommodate approximately 50 sheets of paper and the same size paper as each of the above trays, and it is possible to copy multiple times on one side of the paper, or copy on two sides. This is a tray that temporarily stores copied sheets when copying is performed alternately. A feed roll 507 and a gate 505 are arranged on the artificial side feed path of the duplex tray 11.
This controls switching of paper conveyance according to the combination mode and duplex mode. For example, in duplex mode,
The paper conveyed from above is guided to the feed roll 509 side by the gate 505, and in the case of composition mode,
The paper conveyed from above is guided to the -H combining mode inverter 10 by gates 505 and 506, and then reversed and transferred to the feed roll 510 by the gate 506.
, are guided to the duplex tray 11 side. In order to store paper in the duplex tray 11 and allow it to fall freely to a predetermined edge position, a tray inclination angle of approximately 17° to 20° is generally required. However, in the present invention, since the apparatus is made more compact and the duplex tray 11 is housed in a narrow space, the tilt angle is only 8 degrees at maximum. Therefore, the duplex tray 11 is provided with side guides 561 and end guides 562 as shown in FIG. 19. In controlling these side guides and end guides, once the paper size is determined, the paper is stopped at a position corresponding to the paper size.

A high capacity tray (HCF) is a supply tray that can accommodate dozens of sheets of copy paper. For example, it is often appropriate for customers who do not need to enlarge or reduce originals to make copies, or for customers who do not have many copy images, to purchase a base machine alone.

On the other hand, customers who make a large number of copies or who require complex copying operations often require a duplex tray or a high-capacity tray. As a means to meet these various demands, this copier system has a structure that allows each additional device to be easily attached or removed, and some of the additional devices are equipped with independent CPUs (central processing units). and multiple C
It is decided that distributed control will be performed by PU. This not only has the advantage that the customer can easily obtain the desired product, but the possibility of installing new additional equipment also teaches the customer the possibility of new copying operations. This makes the purchase of this copier system very attractive as it advances the evolution of office processing.

The manual feed tray (MSI) 16 is a tray that can accommodate approximately 50 sheets of paper and paper sizes of A2F to A6F, and in particular can use large-sized paper that cannot be accommodated in other trays. Since this type of conventional manual feed tray manually feeds sheets one by one, it is only necessary to preferentially feed copy sheets from the manual feed tray when manual feed is performed, and there is no need for the operator to select the manual feed tray itself. In contrast, the manual feed tray 16 of the present invention can set a plurality of copy sheets at the same time. Therefore, when you set the copy paper,
If the feeding starts from 6, there is a possibility that the feeding will start when a plurality of sheets of copy paper are set. To prevent this situation, the manual feed tray 16
I am trying to let them make a selection.

In the present invention, compactness is achieved by adopting a configuration in which the nuja roll 513, feed roll 512, and takeaway roll 511 are integrally attached to the tray. After the leading edge of the paper is nipped by the take-away roll 511, a feedout sensor detects the leading edge and pauses it, thereby performing pre-registration to align the transfer position and absorbing variations in paper feeding at the feeder unit. are doing. The fed paper is fed to the transfer position of the photosensitive material belt 4 via the aligner device 515.

(n-4) Automatic document feeder (DADF) In FIG. 20, DADF 1 3 is installed on the platen glass 2 of the base machine 1. This DADF 13
is equipped with a document tray 602 on which a document 601 is placed. A delivery paddle 603 is disposed on the original delivery side of the original tray 602, which allows the original 60 to be sent out.
1 is sent out one by one. The sent document 601 is conveyed to an arcuate conveyance path 609 by a first drive roller 605 and its driven roller 606 and a second drive roller 607 and its driven roller 608.

Further, the arcuate conveyance path 609 is a manual feed conveyance path 610.
A third driving roller 612 and its driven roller 613 are provided at the exit of the arcuate conveying path 609. The third drive roller 612 is movable up and down by a solenoid (not shown), and is configured to be able to approach and separate from the driven roller 613. The horizontal transport path 611 is provided with a stop gate 615 that is rotated by a drive motor (not shown), and a reversing transport path 616 is connected from the horizontal transport path 611 to the arcuate transport path 609 .

A fourth drive roller 617 is provided in the reversing conveyance path 616. Further, a bell II shift roller 619 is provided on the platen glass 2 opposite to the exit of the horizontal conveyance path 611, and a belt 621 stretched between the driven rollers 620 can be rotated in forward and reverse directions. A fifth drive roller 622 is provided at the exit of the belt conveyance section, and a sixth drive roller 623 is provided in the manual feed conveyance path 610. The drive roller 623 is the base machine 1
Two of them are provided in the front and back direction (perpendicular to the plane of the paper in the figure), and are configured to be able to feed two originals of the same size at the same time. Note that 625 is a cleaning tape for cleaning the surface of the delivery paddle ¥03 by the seventh drive roller 626.

Next, referring also to FIG. 21, the photosensors 81 to S12
I will explain about it. Sl is the document 6 on the document tray 602.
01 is a no-paper sensor, S2 is a take-away sensor that detects the passage of a document, S is a feed sensor provided before and after the manual feed conveyance path 610, A registration sensor detects whether the original is at a predetermined position at the stop gate 615 after skew feeding has been corrected, 86 to SIO are paper size sensors that detect the size of the original, and S is a discharge sensor that detects whether the original has been ejected. A sensor S12 is an end sensor that detects the end of the cleaning tape 625.

Next, with reference to FIG. 22, the DADF consisting of the above configuration
The effect of No. 13 will be explained. (A) is a platen mode, in which the original 601 is placed on the platen 2 and exposed.

(b) is the simplex mode, and the document tray 60
2, the originals 601 are stacked with the first side to be copied facing upward. When the start button is pressed, first the first drive roller 605 and the second drive roller 6
07 rotates, but the third driving roller 612 moves upward and separates from the driven roller 613, and the stop gate 6
15 descends and blocks the horizontal fine feed path 611. As a result, the original 601 passes through the arcuate conveyance path 609 and is pressed against the stop gate 615 (■ to ■). This stop gate 6
At position 15, the original is corrected by the skinny roller 627 so that its edge is perpendicular to the horizontal transport path all, and the original size is detected by sensors S6 to S1°. Next, the third driving roller 612 moves downward and comes into contact with the driven roller 613, and the stop gate 615 rises to open the horizontal conveyance path 611, and the third driving roller 6
12, the belt drive roller 619 and the fifth drive roller 622 rotate, and the document is sent to a predetermined position on the platen 2 with the side to be copied facing down, exposed, and then discharged. The same effect occurs when sending a single document from the manual feeding path 610, and in addition to the function of feeding documents one by one, the function of simultaneously feeding two documents of the same size (2-U
P), function to feed large documents (LDC), computer form feeder (to feed continuous paper for computers)
CCF) function.

(C) is the duplex mode, and the process of exposing one side of the document is the same as the steps (2) to (2) in (B) above, but when the one side exposure is completed, the belt drive roller 619 is reversed, and The third driving roller 612 moves upward and separates from the driven roller 613, and the stop gate 615 lowers to block the horizontal conveyance path 611. Therefore, the document is conveyed to the reversing conveyance path 616, passes through the arcuate conveyance path 609, and is pressed against the stop gate 615 by the fourth drive roller 617 and the second drive roller 607 (■ to ■). Next, the third drive roller 612 moves downward and comes into contact with the driven roller 613, and the stop gate 615 rises to open the horizontal conveyance path 611, and the third drive roller 612 and the belt drive opening/roller 619 Then, the fifth drive roller 622 rotates, and the document is sent to a predetermined position on the platen 2 with its back side facing down, and exposed. When the exposure of both sides is completed, the belt driving roller 619 is reversed again, and the sheet is again conveyed to the reversing conveyance path 616, and in the same manner, passes over the platen 2 and is discharged by the fifth driving roller 622 (■ to ■). Therefore, the ejected originals are stacked in the order in which they were first stacked on the original tray 602, with the first side to be copied facing downward.

(If-5) Sorter In FIG. 23, the sorter 19 has a sorter body 652 and 20 bins 653 on a movable cart 651. Inside the sorter body 652, a belt drive roller 656 that drives the conveyor belt 655 and its driven roller 657 are provided, as well as a chain drive sprocket 660 that drives the chain 659 and its driven sprocket 661. These belt drive rollers 65
6 and chain drive sprocket 660 are driven by one sorter motor 658. Conveyor belt 655
A paper inlet 662, a paper outlet 663, and a switching gate 665 driven by a solenoid (not shown) are provided at the upper part of the paper inlet 662, right side of a paper outlet 663, and a switching gate 665 driven by a solenoid (not shown). Further, an indexer 666 is attached to the chain 659 for switching and supplying copy paper to each bin. As shown in FIG. 24, the rotation of the drive shaft 671 of the sorter motor 658 is transmitted to a pulley 673 via a timing belt 672. The rotation of the pulley 673 is transmitted to the belt drive roller 656 and to the chain drive sprocket 660 via a gear device 674.

Next, the operation will be explained with reference to FIG. 25. (A) shows the non-sort mode, and the switching gate 665 is in the non-sort position and sends the copy paper to the uppermost discharge tray. (B) indicates the sort mode, and the switching gate 6
65 is switched to the sorting position, the odd-numbered sheets are conveyed from the top to the bottom bin to the odd-numbered bins, and the even-numbered sheets are conveyed from the bottom to the top bin and conveyed to the even-numbered bins. transported to. This reduces sorting time.

(c) and (d) show the stack mode, (c) shows an example of four copies of four originals per original, and (d)
This is a case where the maximum number of sheets stored per bin is exceeded. For example, when the number of sheets exceeds 50, the sheets are stored in the next bin.

(II-6) Belt area The belt area consists of an imaging system and a marking system.

The imaging system is managed by the 1MM subsystem 34, which writes and erases latent images.

The marking system is managed by a marking subsystem 35, which performs charging, exposure, surface potential detection, development, transfer, etc. In the present invention, the 1MM subsystem 34 performs panel management on the belt, batch formation, etc. to achieve high copy speed and high image quality as described below.
and marking subsystem 35 cooperate with each other.

FIG. 26 is a diagram showing an outline of the belt.

An organic sensitive material belt 4 is arranged within the base machine 1. Since organic photosensitive material belts are coated with multiple layers such as a charge generation layer and transfer layer 1 to form a photosensitive material, they have a greater degree of freedom in manufacturing compared to photoreceptor drums, which form photosensitive materials by vapor depositing Se. It is easy to do this, so costs can be reduced.
Also, since the space around the belt can be increased, the layout can be easily done.

On the other hand, belts expand and contract, and the diameter of rolls also changes due to temperature differences, so a belt hole is provided at a certain distance from the belt seam to detect this, and pulses are generated according to the rotational speed of the main motor. is generated by an encoder to form a machine clock, and by constantly counting the -period machine clock, a pitch signal that becomes a reference for starting the carriage according to the expansion and contraction of the belt,
Correct the registration timing.

The organic photosensitive material belt 4 in this device has a length of 1 m or more, and is designed to hold 4 A4 size sheets and 3 A3 size sheets, but since the belt has seams, it is always necessary to use a panel (image formed on the belt). Formation area) If you do not manage it, you will not be able to make a copy of the specified panel. Therefore, the position of the panel is determined based on the belt hole provided at a certain distance from the seam, the number of panels (peach number) to be placed on the belt is determined according to the copy mode and paper size specified by the user, and then the start is started again. When the panel for first copying by pressing the button comes to the get park position near the roll 201, it issues a signal, indicating that a copy can be made from here.

The organic sensitive material belt 4 is a charge corotron (charger) 21
1, and is uniformly charged and driven clockwise in the figure at a constant speed. Then, when the first panel arrives a certain time before the register (exposure location) 231, a pitch signal is output, and the timing of carriage scan and paper feed is determined based on this signal. The belt surface charged by the charge corotron 211 is exposed at an exposed location 231
exposed to light. A light image of a document placed on a platen glass 2 placed on the top surface of the base machine 1 is incident on the exposure portion 231 . For this purpose, the exposure lamp 1
02, a plurality of mirrors 101 to 113 and an optical lens 10 that transmit reflected light from the illuminated document surface.
8 are arranged, and among these mirrors 101 is scanned when reading the original. Also mirror 110.
111.113 constitutes the second scanning optical system, which is P
I S (Precession I mageSc
Since there is a limit to increasing the process speed, the second scanning optical system scans in the opposite direction to the belt movement direction so that the copy speed can be increased without increasing the process speed. The relative speed is increased to achieve a maximum of 64 sheets/min (CPM).

An electrostatic latent image corresponding to the original is formed on the organic sensitive material belt 4 by the image information exposed in a slit shape at the exposure location 231 . And IEL (Interimage Lamp)
After erasing unnecessary images, images between images, and side erasing in step 215, the electrostatic latent image is transferred to a developing device 21, which normally uses black toner.
6 or developed by a color toner developing device 217 to create a toner image. The toner image moves with the rotation of the organic sensitive material belt 4 and passes near a pre-transfer corotron (transfer device) 218 and a transfer corotron 220. The pre-transfer corotron 218 is generally used to weaken the electrical adhesion of toner by applying an alternating current to facilitate the movement of toner. Also, since the belt is made of a transparent material, before transfer, a pre-transfer lamp 225 (also used for erasing) irradiates the belt with light from the back to further weaken the electrical adhesion of the toner, and transfer is performed. make it easier

On the other hand, the copy paper stored in the supply tray of the base machine 1 or the copy paper fed manually along the manual feed tray 16 is sent out by the feed roll, guided to the conveyance path 501, and connected to the organic photosensitive material belt 4. It passes between the transfer corotrons 220. In principle, paper feed is LEF (Long Edge Feed).
), and the registration gate is controlled to open and close so that the leading edge of the paper and the exposure start position match at the tacking point, and the toner image is transferred onto the copy paper. Then, the paper and the photosensitive belt 4 are peeled off by a corotron 221 and a strip finger 222, and the copy paper after transfer passes between a heat roll 232 and a pressure roll 233 to be thermally fixed, and then transferred to a conveyor roll 234, 235. and is discharged onto a discharge tray (not shown).

The sensitive material belt 4 from which the copy paper has been peeled off is made easy to clean by a pre-clean corotron 224, unnecessary charges are erased by light irradiation from the back side by a lamp 225, and unnecessary toner, dust, etc. are scraped off by a blade 226. It will be done.

Note that patches are formed between images on the belt 4 by a patch generator 212, and the electrostatic potential of the patch portion is detected by an ESV sensor 214 for density adjustment. Further, as described above, the belt 4 has holes, which are detected by the belt hole sensor 213 to detect the belt speed and control the process speed. Also A
DC (Auto Density Control)
The sensor 219 detects the degree of toner adhesion by comparing the amount of reflected light from the toner on the batch area with the amount of reflected light when there is no toner, and the pop sensor 223 detects whether the paper is wrapped around the belt without being peeled off. The case is detected.

FIG. 27 shows how the photosensitive material belt 4 is divided into panels.

Since the belt 4 has a seam part 251, the image is not placed there, and a belt hole 252 is provided at a certain distance l from the seam part, for example, with a circumference of 1158 m.
In this case, l is 70 cities. 253 and 254 in the figure are the first and last panels when the sensitive material belt surface is divided into N pitches, B in the figure is the panel interval, C is the panel length, D is the panel pitch length, and it is divided into 4 pitches. 289 for
In the case of ゜5InI1113 pitch division, there are 386 strokes, and in the case of 2 pitch division, it is 579 strokes. The seam 251 is set at the center of the LE (Lead Edge) of the panel 253 and the TE (Tail Edge) of the panel 254 so that A=B/2.

Note that the LE of the panel needs to match the LE of the paper, but the TE does not necessarily match, but matches the maximum paper TE to which the panel is applied.

FIG. 28 is a block diagram schematically showing the functions of the 1MM subsystem.

To outline the functions of the IMM subsystem 34, it performs serial communication with the IEL subsystem 40 via a pass line, sends interrupt signals via a hot line for highly accurate control, and manages image formation. 35, sends a control signal to the CHM subsystem 33 to control the belt.

It also detects holes in the organic photosensitive material belt 4 to control the main motor, and also determines the panel forming position and performs panel management. In addition, in the case of low-temperature transfer, the fuser mold is rotated to maintain the fixing roll at a predetermined temperature so that rapid copying can be performed. and,
When the start key is pressed, the machine enters the setup state and ■ prior to copying. Adjust constants such as DP,
When entering the copy cycle, the leading and trailing edges of the image are erased based on the document size to form the necessary image area.

A patch is also formed in the inter-image area to form a patch for toner density adjustment. Furthermore, if a hard down factor such as a jam or a belt failure is detected, the belt is stopped or the machine is stopped by communicating with the sequence manager.

Next, the human output signal and operation of the tMM subsystem will be explained.

Black toner bottle 261, color toner bottle 26
The toner detection signal in step 2 is input and the remaining amount of toner is detected.

The optical registration sensor 155 inputs an optical registration signal that serves as a reference for the output PG request signal, bias request signal, and ADC request signal from the 1MM subsystem to the marking subsystem.

The document size is input from the platen document size sensors S6 to S10, and from this and the paper size, the IEL215
The scrubbing area is determined by

A belt hole signal is input from the belt hole sensor 213, and the main motors 264 and 265 control the process speed to correct for variations in the belt rotation time.

Two main motors are provided to enable operation at an efficient operating point, to enable efficient output of motor power depending on the load condition, to use electric power effectively, and to improve stopping position accuracy. The motor performs regenerative braking. The motor can also be driven in reverse. This is to remove paper powder and toner scum that accumulates on the front side of the blade when cleaning is performed with the blade in close contact with the photosensitive material belt. In addition, belt drive by the motor is performed via a belt clutch 267.
Only the belt can be stopped selectively. Pulses are generated from the encoder in synchronization with the rotation of this motor, and are used as machine clocks to obtain machine clocks that correspond to the belt speed.

Note that if the belt hole sensor 213 cannot detect a hole for a certain period of time or if the size of the hole changes, the IMM will notify the sequence manager of this and the machine will be stopped.

In addition, the 1MM subsystem is the IEL subsystem 40
In addition to performing serial communication with the
It transmits L image signal, ADC batch signal, and EEL black band signal. Unnecessary images are erased using the IEL image signal, and the IEL subsystem 40 uses the ADC batch signal to define the shape and area of the batch area formed by the batch generator 212, and adjusts the amount of charge to adjust the electrostatic potential. is adjusted to a constant potential of 500 to 600 cm. In order to prevent the belt 4 from being damaged by the blade 226, the IEL black band signal forms a black band between the images at predetermined intervals to adhere toner and act as a kind of lubricant. This prevents the belt 4 from being damaged even when copying is performed when toner I is extremely low, such as in a situation where the amount of toner I is extremely low.

Furthermore, the IMM communicates with the marking subsystem 35 via a hotline, and uses the optical register signal as a reference to generate batch formation request signals, bias request signals,
Sends an ADC request signal.

In response, the marking subsystem 35 drives the patch generator 212 to form a batch, and also
The SV sensor 214 is driven to detect electrostatic potential, and the developing devices 216 and 217 are driven to form a toner image. It also controls the drive of a pre-transfer corotron 218, a transfer corotron 220, and a pig corotron 221.

A pitch reset signal ■ is sent from the IMM,
The carriage start timing is determined based on this.

Further, a detection signal indicating whether or not a color developing unit is installed is input, and it is detected whether the toner in the developing unit is black or color.

A registration gate trigger signal is sent from the IMM to the CHM subsystem 33 to control the paper so that the leading edge of the image coincides with the paper at the tuffing point, and if it is necessary to correct the opening timing of the registration gate, the amount of correction is is calculated and sent.

Further, the toner scraped off by the blade 226 is collected in a collection toner bottle 268, and a detection signal of the amount of toner in the bottle is input to the IMM, and an alarm is issued when a predetermined amount is exceeded.

The IMM also drives the fan motor 263 to prevent an abnormal temperature rise, so that the environmental temperature is within the permissible temperature range and copies with stable image quality can be obtained.

FIG. 29 shows a timing chart.

The reference time for control is the optical registration sensor position. Predetermined time of optical registration sensor on/off signal (
TI) After that, IEL is turned off.

In other words, it is on until T1 and the tip is erased,
After T2, it is turned on to erase the rear end. In this way, image formation is performed using the IEL image signal, and by controlling the registration gate timing, the leading edge of the paper at the tacking point and the leading edge of the image are aligned. After image formation is completed, the batch generator request signal (T from the reference time)
5) generates an ADC patch signal and forms a patch in the inter-image. After batch formation, a bias request signal is issued (after T6) to perform development, and then an ADC request signal is issued (after T7) to detect toner density. Further, a black band is formed in the inter-image by the black band signal.

In addition, during the AE (Auto Exposure) x scan, the IEL image word ON10
FF is not performed.

32 is always aware of it.

Of course, information that only each subsystem needs to know, such as the fact that a document has been placed on the document tray, only needs to be known by the U/I, especially the SQMG.
This information cannot be conveyed to R. Thus SQMG
The entire device is controlled organically and efficiently by H.

(III-2) System module configuration 131 is a module correlation diagram of the system.

Fail check processing is being performed due to (the RAM area allocated for transmission data is full).

(1-3) State management In this device, state management is performed for the main body and each subsystem from the viewpoint of ease of control, and the relationship between these states is hierarchical. That is,
Above each subsystem such as the belt state and marking state, there is a processor state that shows what state each subsystem is in. Furthermore, above the input state, processor state, and output state, there is a processor state that shows the state of the entire machine. There is an M/C state that indicates whether the

(A) Machine state Figure 32 shows the M/C state. After power is turned on,
When each application is activated for the first time, the initialization state to which it transitions is a state in which each remote distributes NVM data necessary for control prior to controlling the M/C (■). In the case of the normal mode, a transition is made from the initialization state to the 5TANDBY state (■), which provides the user with an opportunity to set the copy mode. Also, when in the diagnosis mode, it becomes a diagnosis state where the configuration and control data of the M/C are set (■
). Then, in the 5TANDBY state, when the start button is pressed and a start command is received from the U/I, the PR performs the copy operation according to the user's request.
It enters the OGRESS state (■), and when the requested copy is completed and the M/C must be brought down, it enters the OGRESS state (■). This state is a state that gives the user an opportunity to start a copy restart, and when a start command is received, the program transits to the PROGRESS state again (■). When it is necessary to stop the M/C due to a failure or operation of the stop key or all clear key, 5OFT DOWN P is used to wait until the M/C has stopped in the best condition.
The system enters the AUSE state (■), and the message "Please wait" is displayed. The copy display in 5TANDBY is "Copying possible", the message display in PROGRESS is "Copying", 5OFT DOWN
The copy display on Co1n is "Copy possible".

When INPUT, processor, and 0UTPUT all stop, if there is a jam, PURGE is used to give the user an opportunity to remove the cause of the jam.
Transition to the 5TANDBY state (■). This P.U.
When in the RGE 5TANDBY state, press the start key and SQMGR receives the start command from U/■, then it will enter the PURGE state (■),
The M/C will perform the recovery work that it can do by itself. In addition, 5OFT DOWN PAUSE

If there is no B, a transition is made to 5TANDBY (■). Also, if you cancel the JOB due to 5TANDBY and do not need to PURGE the document, use 5TANDBY.
Maintain the BY state (o).

By performing this kind of state management, SQMGR can always grasp the state of the M/C and
/C is in overall control.

(B) Processor state FIG. 33 is a diagram showing processor states.

State division divides the state from power ON to copy operation and after the copy operation is completed into several parts, determines the jobs to be performed in each state, and moves to the next state if all jobs in each state are not completed. This is to ensure the efficiency and accuracy of control by preventing the I know what's going on and decide what I should do. Each subsystem is also divided into states, and a flag is similarly determined corresponding to each state, and the main system refers to these flags to understand and manage the state of each subsystem.

First, when the power is turned on, the processor enters a state of initialization and determines whether it is in diagnosis mode or user mode (copy mode). Diagnosis mode is a mode used by service personnel for repairs, etc., and performs various tests based on conditions set in NVM.

In the initialization state in user mode, initial settings are performed based on the contents of NVM. For example, the carriage is set at the home position, the lens is set at 100% magnification, and each subsystem is commanded to initialize. When initialization is complete, it transitions to standby.

Standby is when all subsystems have finished their initial settings and
This is the state until the start button is pressed, and the message "Please wait" is displayed on the fully automatic screen. Then, turn on the coltslamb and perform the user-medium rotation for a predetermined period of time,
When the fuser reaches the predetermined control temperature, U/I
displays "You can copy" in the message. This standby state takes about several tens of seconds when the power is turned on for the first time.

Setup is a preparatory state for copying which is activated by pressing the start button, the main motor and sorter motor are driven, and constants such as V1)DP of the photosensitive material belt are adjusted. Also, the ADF motor is ONL, 1
Feeding of the first original is started, the first original reaches the registration gate, the original size is detected, the tray and magnification are determined in the APMS mode, and the ADF original is placed on the platen. Then, the second document from the ADF is sent to the registration gate, and a transition is made to cycle up.

Cycle up is a state in which the belt is divided into several pitches and panel management is performed until the first panel reaches the get park point. In other words, the pitch is determined according to the copy mode, and the optical subsystem The C8M subsystem and 1MM subsystem are then notified of the copy mode, and when the magnification set is recognized, the scan length is determined based on the magnification and paper size, and the optical subsystem Then, the marking subsystem is notified of the copy mode, and when the marking subsystem has finished starting up, the 1MM subsystem checks the panel L/E determined by the pitch, and the first copy panel is found. When you reach the Get Park Point, you become a Get Bar Credit and enter the cycle.

The cycle is in the state where the copy operation is in progress, and the ADC (Auto
atic 'Density Control
+), AE (Automatic Exp
copy operation is performed repeatedly while performing DDP control, etc. When the R/L-count number is reached, the originals are exchanged, and when this is done for a predetermined number of originals, a coincidence signal is output and cycle down is started.

Cycle down is a state in which carriage scanning, paper feeding, etc. are finished, and the copy operation is cleaned up. Each corotron, developing machine, etc. are turned off, and the panel next to the last used panel is stopped at the stop park position. Manage the panels so that only certain panels are used and do not cause fatigue.

After this cycle down, the machine normally returns to standby, but if you press the start key again while copying in platen mode, the machine returns to set-up. Furthermore, even from set-up or cycle-up, if a cycle-down factor such as a jam occurs, a transition is made to cycle-down.

Purge is the state when a jam occurs, and when the jammed paper is removed, the other papers are automatically ejected. Normally, when a jam occurs, any state transitions from cycle down to standby to barge. Then, when the purge ends, it transitions to standby or set-up, but if a jam occurs again, it transitions to cycle down.

Belt down occurs when a jam occurs on the tray side from the tacking point, and by disengaging the belt clutch, the belt drive is stopped and the paper ahead of the belt can be ejected.

A hard down is when an interlock is opened, resulting in a dangerous situation, or when a machine clock failure occurs, resulting in loss of control, and the 24V power supply is cut off.

Then, when these belt-down and hard-down factors are removed, a transition is made to standby.

(nI-4) Interface Correlation Next, data exchange between the SQMGR and each subsystem will be explained using initialization processing as an example.

FIG. 34 is a correlation diagram of inter-subsystem interfaces in initialization processing.

When the power is turned on by the user, initialization processing is performed. After power on, SQMGR is 1. After 5 seconds, various values necessary for each subsystem to start up stored in NVM are sent to each subsystem. The sorter sends a C0NFIG command to the SQMGR, informs it whether the sorter is one or two series, and when the U/I returns initialization end information, the SQMG
R signals the system state to DADF and marking. After turning on the 24V power, an initialization instruction is given to the OPT. This is because initializing the OPT requires driving the lens and carriage. Next, select R for normal copy mode or diagnosis mode.
Notify each subsystem of the UN mode. This information was sent to SQMGR along with the initialize end command from U/[. And ADF
INPUT TRAY 5TATU of mode or not
S. Interlock 5 When information on TATUS is received from DADF, this information is notified to U/1. Also, from CHM, tray 5T notifies the status of the tray.
When ATUS information is sent, this information is also notified to the U/I. During this time, the heating of the fuser starts, two lamps are turned on, the DEVE retract is operated, the information of the fuser 5 TATUS is sent to the SQMGR, and this information is sent to the U/I. When the initialization end is notified from each subsystem, S
QMGR changes system state, i.e. standby to CHM
, marking, and informs the U/I, and also rewrites the processor state to set it to standby state. U/
I is an automatic screen that instructs 100% magnification and A4 size paper, enters a state in which keys can be accepted, the display shows "Copy ready", and the initialization process ends.

In this way, SQMGR issues necessary instructions to each subsystem, receives reports from each subsystem that processing has been carried out as instructed, constantly grasps the status of each subsystem, rewrites the system state, and , the necessary information is notified to the U/I and displayed.

(I[l-5) System environment Ilo, which is directly controlled by SQMGR, has the ability to turn off the power after a predetermined period of time in the event of pilling or failure, or to receive copy services using a key or card. These are service kits, etc., and these processes include CHM, sorter, U/I setting number of sheets, etc.
This is because it is performed by aggregating data from each subsystem, and having one existing subsystem perform this processing is different from other functions.

For example, taking pilling as an example, this embodiment provides a pilling system that supports new functions such as colorization, and mainly consists of TOTAL pilling, MODAL pilling, and C0LOR pilling.

(1) TOTAL pilling counts the number of copies used in 1st DEVE, and counts the number of sheets in the duplex tray and the number of sheets stored in the sorter.

(2) MODAL pilling is a service for large users by counting each document up to a predetermined number within the range of 1 to 999 set in NVM, and not counting beyond that number. We are making it possible to do this.

(3) COL OR pilling counts the number of copies made using 1stDEVE and 2ndDEVE, and separately counts the number of copies made for A2 size paper that can only fit in MSI as A2 paper pilling.

With this method, for example, when copying in black and red composite mode, when copying in black (LstDEVE), TO
Counts both TAL pilling and C0LOR pilling, and when copied in red (2nd DEVE), COL'O
Only R-pilling is counted.

Note that the pilling counter turns on when the paper is normally ejected, and jammed paper is not counted. In addition, the pilling OFF timing is
This is done 100 m5ec after N, and this means that the shorter number is the shorter number on the software, but since it is counted by a mechanical counter, it takes a certain amount of time to operate this, and it also takes a certain amount of time to start the next paper. This is because it cannot be too long for counting.

In addition, since MODAL pilling counts the number of copies per original, it is necessary to use a software counter instead of a mechanical counter. , and also counts pilling by turning off the sensor to the duplex tray. Additionally, an interrupt MODAL counter is provided, and counts during interrupt jobs in the same way as the MODAL pilling counter.

Pilling control in the event of an error is the same for jams and interlock open, and paper ejected by purge is not counted. In addition, in the case of job cancellation by the clear key or all clear key, the soft counter for MODΔL pilling is used in the same way as in the case of a jam, and at the time of an interrupt, the MODAL counter interrupts counting, and the interrupt MODAL counter performs counting. Also,
In the case of no paper or LOWTONER, neither is counted.

(I-6) Complex function SQMGR is a job that spans between each subsystem,
Alternatively, various controls are performed for jobs such as state management, and representative ones are explained below.

(A) Restart The purpose of restart is to increase productivity by allowing the next job to be accepted before the M/C stops. scan 5CAN
M/C state (system state) is 5OFT DOWN from PROGESS by the next pitch signal.
INPUT from the time when it becomes C0IN and the processor state changes from CYCLE to CYCLE DOWN.
Until the main body and 0UTPUT are completely stopped, if the start key is pressed again, the job will be accepted.

When the M/C state becomes 5TANDBY state, INPU
The T, main unit, and 0UTPUT have completely stopped, and subsequent starts will not be treated as a start, but will be treated as a normal start from a stop. And at restart, Figure 35 (b)
The M/C state is 5OFTDAWNCO as shown in
[N changes to PROGESS, and the processor state changes from CYCLEDAWN to 5ETUP. In addition, if you restart XERO while it is stopping, it will immediately stop the stopping and enter the startup sequence, and if you restart it during stop park, the stop park operation will immediately stop and it will enter the startup sequence. . Furthermore, if the belt is restarted during a reversal operation, the start-up sequence begins after the reversal operation is completed.

In addition, in the platen mode, a new job is accepted and started using the start button from the scan return of the last copy, and 5ADF2UP, LDC
In this mode, a new job is started if the original is already set at the time of the last scan return of the registered original, or if the original is set before the machine stops. In addition, in ADF mode, cards can be consecutively (
A restart is only possible if the card is inserted (successively). The timing for starting the machine is after the last paper is ejected. In CFF mode, there is no reception for job start.

(B) Panel division Because conventional copying machines determine the number of panel divisions mainly based on paper size, for example, when the magnification is increased and the optical scan speed becomes slower, the scan start signal for the next panel cannot be issued. However, in this embodiment, the number of panel divisions is adjusted according to the magnification, paper feed direction length, set number of sheets, paper feed tray, input mode, etc. has been decided. This determination is made by the SQMGR based on the copy mode in the M/C start command sent from the U/I to the SQMGR when the start key is pressed in the standby state. As a result, optimal panel division is always performed according to the copy mode to maintain CPM at a high level.

(C) Original automatic recovery In this example, ΔDF, double-sided original/single-sided copy (D/S
), a paper jam occurs in double-sided original/double-sided copy (D/D) mode, and the side of the original that is being
If the side of the next original is different from the one to be copied, the original is not purged as in the conventional method, but the original is automatically reversed and copying can be started at the next start. In addition, REG
Detection of the side of the document surface that is IL or SQ is performed using REGI INF command data sent from DADF.
MGR is making the decision.

([-7) Jam Priority Determination Process (Main Part of the Present Invention) In the present invention, a plurality of sensors are arranged in the device, a timer is set when a document or paper steps on the sensor, and the timer is activated. By monitoring, the position of the original or paper is monitored. A jam that occurs during operation of the apparatus is classified as a dynamic jam, and a jam that is detected at startup or when the power is turned on is classified as a static jam. In the case of a dynamic jam, for example, regarding the main unit, the CHM monitors the position of the paper, so the position can be completely grasped, but in the case of a static jam, the M/C must be temporarily stopped and the interlock activated. If the paper is opened and some of the paper is ejected, the timer will be reset and the CHM will lose the paper position data.
The difference is that you won't know where the remaining paper is unless you step on the sensor. In addition, jams detected by the sensor include paper being finely fed and a certain sensor turning on when it should be turned on, but not turning on, or turning on and then turning off when it should turn off but turning OFF.

There is no OFF jam. In this case, if the distance between the two sensors is far, it is necessary for both sensors to detect O, N jams, and OFF jams, but if the two sensors are close, the upstream side O of the sensor
Since an FF jam can be detected by an ON jam of the downstream sensor, there is no need for an OFF jam of the upstream sensor.

In the present invention, the jams are prioritized and
Regarding dynamic jams, only jams with a high priority are displayed, and when that is cleared, a jam with the next highest priority is displayed, and thus jams are displayed in order according to the priority order.

Further, in the case of a static jam detected at the start, the jams are sequentially displayed at predetermined time intervals, for example, at 5 second intervals, starting from the highest priority.

Further, in the present invention, the order of priority for jamming is input device, output device, and main body. The reason we prioritized clearing input device jams is because when copying, it is first necessary to protect the original.
This is from an ergonomic point of view, as it allows the user to clear a jam in the same posture as when copying.

Next, the reason why the output device is given priority over jam clearing on the main unit is that, for example, if a jam occurs in the docking area between the main unit and the sorter, if you try to clear it from the main unit, the interlock will open and the jam will open. You cannot clear the jam unless you pull out the user unit and reach to the rear of the user unit to remove the paper.On the other hand, if you do it from the sorter side, you can easily clear the jam by opening the top of the sorter and pulling out the paper in that state. Taking this situation into consideration, clearing jams on the sorter side is prioritized over the main unit.

Further, the size of the jam zone mainly depends on whether the jam clearing method is the same or different, and if the jam clearing method is the same, different jams are considered to be the same jam zone.

(III-7-1) Jam detection sensor and its arrangement No. 36
The figure is a diagram for explaining a jam detection sensor and its arrangement.

As shown in Figure 36 (a), the main body, sorter, DADF
A plurality of sensors are arranged as shown in FIG. 36 (b) to detect jams in each of the two areas.

And it should turn ON when paper is detected, but it turns ON.
An ON jam when there is no 0FFL, or an OFF jam that is ON but should be OFF but is not 0FFL is detected.

Regarding the main body, 14 sensors are arranged, and sensors 1 to 3 are feedout sensors that detect whether or not paper is discharged from the upper tray, middle tray, and lower tray, respectively.

Sensors 4 and 5 are sensors related to the duplex tray, and are a feedout sensor that detects whether or not paper has been ejected from the duplex tray, and a transport sensor that detects whether or not the paper has passed through the duplex tray. .

Sensor 6 is a registration gate sensor located at the registration gate position, sensor 7 is a pop sensor that detects when the paper is stuck to the belt and is drawn in, and sensor 8.9 is a sensor related to the user, which is located at the entrance and exit respectively. Ru.

Sensor 10 is an EXIT sensor that detects whether or not paper has been ejected from the main body, sensor 11 is a sensor placed toward the intermediate tray, and sensor 12 is a feedout sensor that detects paper ejection from the large capacity tray. 13
．． 14 is a sensor that detects paper discharge from the MSI and detects no paper. The sensor 14 is not used for detecting a jam because it only detects blank paper.

Regarding the sorter, in the case of a double sorter, five sensors are arranged, a non-sort sensor and an index sensor are arranged in each sorter, and a transport sensor 33 is arranged between the sorters. The non-sort sensor detects the paper when not sorting, the index sensor detects the paper ejected to each bin when sorting, and the transport sensor detects the paper ejected from the first sorter to the second sorter.
Detects paper being ejected to the sorter.

Five sensors are arranged in the DADF, each of which is a sensor 31 that detects manually fed paper, a REGI sensor 32 that detects that paper is set at the SREGI position, and a feed sensor 33 that detects feed from the document tray.
, a no-paper sensor 34 that detects whether there is a document in the document tray, and an EXIT sensor 35 that detects that the document is ejected from the DADF. sensor 3
4 only detects paperless paper and has no particular relation to jam detection.

(II[-7-2>Jam priority module correlation 3rd
FIG. 7 is a diagram showing module correlation for performing jam priority determination processing.

ON jam and O detected by input device sensor group 801, main body sensor group 802, and output device sensor group 803, respectively.
FF jam is DADF37, C8M33.5ORTE
is transmitted to SQMGR32 via R38, where SQ
MGR creates a jam command as described below and uses U/
Send to 136.

The U/I 36 reads the data added to the jam command in a predetermined order, and displays the jam screen in order of jam priority.

(I-7-3) Jam command FIG. 38 is a diagram showing the jam command data structure.

SQMGR creates jam data as shown in FIG. 38 using data from DADFSCHM and 5ORTER. In other words, data 1 is added to the code number of the jam command.
~5 is added. Data 1 indicates the cause jam code, and if there is a jam in the jam clear check performed before starting the M/C, the cause jam code is set to 0 as a static jam, and otherwise as a dynamic jam. Data 2 to 5 indicate jam zones; area A in the figure is a jam in the input device, area B is a jam in the output device, and area C is a jam in the main body.

A jam command and data are sent from the SQMGR to the U/I when an ON jam or an OFF jam is recognized for each sensor.

That is, when the occurrence of a jam is detected, the bits of the corresponding jam zone are set to 1 and transmitted to the U/I. If a jam is detected in the jam clear check performed before starting the M/C, the cause jam code is set to 0 as a static jam, the bit of the corresponding jam zone is set to 1, and a message is sent to the U/I.

After a jam occurs, if there is a change in the jam zone during a jam clear check, it is sent to U/1 each time.
I updates the data by overwriting the data. Also, if a jam is detected in the jam clear check when the interlock is closed when the power is turned on, the jam code is set to 0, the bit of the corresponding jam zone is set to 1, and the U/
At the same time, U/I overwrites the data and updates the data.

The U/I receives such data and also issues machine state commands 5TANDBY or PURGE 5TAN.
When DBY is received, that is, when an M/C stop condition occurs, a jam screen corresponding to the cause jam code and jam zone is displayed. In this case, the U/I looks at the jam zone, notifies the user of instructions to clear the jam in the order of input device, output device, and main body, and clears the jam display when all the jam zones are cleared.

In this regard, the dynamic jam will first be explained with reference to FIG. 38. In FIG.
The data is checked in the order of -7→1-8→1-9→1-10, and if bit 1 is set, a jam is indicated as a jam occurring in that zone. in this case,
The zone that is viewed first has the highest priority. Next, check the output device jams in area B, that is, in the order of 1-6-1 → 1-6-2, and if bit 1 is set, it means that all the jams detected before have been cleared. The jam is displayed. Furthermore, in the C area, that is, the main body, ■-4→1
-3→・・・3-3-2→3-33-3→3-1→・・
- Check in the order of 2-4 → 2-2 → 2-3 → 1-5, and if there is a zone where bit 1 is set, the jam will be detected when all previously detected jams are cleared. It will be displayed.

In this way, a jam priority is determined based on the order in which data is read out, a jam with a high priority is displayed, and when the jam is cleared, a jam with the next highest priority is sequentially displayed.

In addition, in the case of a static jam, the display will be displayed for 5 seconds in order from the highest priority according to the same priority order, and when the jam is cleared, the display for the cleared jam display will be erased one by one. Become.

(1-7-4>Relationship between jam zone and sensor FIG. 39 is a diagram showing the correspondence between the jam zone, jam code, sensor, and jam screen.

FIG. 39(a) relates to DADF.

Jam zones 1-7 correspond to ON jams and OFF jams of the REG I sensor 32 in 5ADF mode and LDC mode, that is, when documents are fed manually.
Is it located at the EGI sensor 32? REG [sensor 3
This is a case where you have reached position 2 but are stuck there. To clear the jam in this case, the document is pulled out from the 5ADF entrance side in both ON and OFF jams, so they are divided into the same jam zone.
Both IN sensor 31 and REG I sensor 32 are OFF.
I will do it.

Jam/-71-81tEX IT Center? 35(7)O
These are N jam and OFF jam. ON jam means that the document still remains in the DADF, and OFF jam means that the document has not been ejected completely. In both cases, the platen cover must be removed. Since you have to open the DADF or open the cover of the DADF ejection section to pull out the original, it is divided into the same jam zone, and clearing the jam turns off all the sensors except for the no-paper sensor 3. Become.

Jam zones 1-9 are for original 5i in ADF mode.
After the de2 scan is completed, the REGI sensor 32 is turned on during inversion to invert and eject the document again.
These are jams and OFF jams, and in both cases, you have to open the platen cover or open the DADF cover to clear them, so they are divided into the same jam zone, and clearing the jam turns sensors 32 and 33 off. do.

The jam zone 1-10 is for document S r d e l ,
That is, when feeding from the document tray, and when feeding the document 5ide.
This is an ON jam and an OFF jam of the sensor 32 two scans ago, that is, when inverting the document, and this is basically the same as clearing the jam in jam zones 1-9, but the scan for the document has not yet been completed. Therefore, it is distinguished from the jam zone 19, and the resensors 32 and 33 are turned off by clearing the jam.

FIG. 39(b) relates to a sorter.

Jam zone 1-6-1 is the ON jam and OFF jam of sensors 21 and 22, and the jam on the continuous sorter side.
Since the continuous sorter is opened to clear the jam, the jam zone is the same, and all sensors in the sorter are turned off when the jam is cleared.

Jam zone 1-6-2 is an ON jam or an OFF jam of the transport sensor 23, non-sort sensor 24, and index sensor 25 on the double sorter side and when discharging from the single sorter to the double sorter. Since the jam is also cleared from the dual sorter side, the jam zone is the same, and all sensors in the sorter are turned off by clearing the jam. FIG. 39(c) relates to the main body.

Jam zones 1-1 to 1-3 are the ON jam of the feedout sensor of the lower, middle, and upper trays, respectively. Jam zone 1-4 is the ON jam of the feedout sensor of the large capacity tray. Jam zone 1-5 is the ON jam of the MSI. This is a jam when the feedout sensor is ON or OFF, and the paper does not come out of the tray. Since each location is different, the jam clearing method is different, and the jam zones are also different. By clearing these jams, each feedout sensor is turned off.

Jam zone 2-1 is an OFF jam of the feedout sensors 1 to 3 of the upper tray, middle tray, and lower tray, and the transport sensor 5 of the duplex tray, and each sensor is ON but there is no 0FFL, that is, the paper is is jam that has not been completely ejected from the tray,
Since the interlock is opened and pulled out to clear the jam in the same place, the jam zone is the same.

By clearing these jams, each sensor l,
2. 3. 5 will be turned off.

In addition, in jam zones 1-1 to 1-3 and 2-1,
ON jam and OFF jam are separated, but this is ON
In the case of a jam, the paper is not coming out from the upper, middle, or lower trays, and the paper remains in the tray, so the jam is cleared by pulling out the tray. In the case of an OFF jam, the paper is not completely removed from the tray. This is because the paper is torn if the tray is pulled out, so it is necessary to open the interlock to clear the jam, and the method for clearing the jam is different.

Jam zone 2-2 is RE when not in MSI mode.
ON jam and OFF jam of GI sensor 6,
Both jams occur near the REGI sensor 6 and must be cleared by opening the interlock, so they are in the same jam zone, and the sensor 6 is turned off when the jam is cleared.

Jam zone 2-3 is HCF feedout sensor 12
This is an OFF jam, which occurs when the paper is not properly ejected from the HCF, and by clearing this, the sensor 12 will be turned OFF.

Jam zone 2-4 is the ON jam and OFF jam of REGI sensor 6 in MSI mode, and
The reason why the jam zones 2-2 and 2-4 are divided depending on whether the mode is active or not is because the paper transport paths are different. This jam clearing turns off the sensor 6.

The jam zone 3-1 is a jam zone detected by the pop sensor 7, and a sensor 8 provided at the user's population that is turned on and off.
It's FF Jam. In other words, the paper progresses through the ON and OFF states of the REGI sensor 6, and then the ON state of the sensor 8 installed in the user's population, and should not normally progress toward the pop sensor 7, so if the paper is detected by the sensor 7, it will immediately jam. The purpose is to Of course, this can be detected even if sensor 8 turns on the jam, but if you wait for that to happen, the paper will get deep into the pop sensor side, and in that case, it will be extremely troublesome to remove the paper, and there is a risk that the cleaner blade will be damaged by the paper. Therefore, if it is detected by the pop sensor 7, it is immediately recognized as a jam. Therefore,
The pop sensor 7 jam and the ON and OFF jams of sensor 8 are set in the same jam zone. The sensor 8 is turned off by clearing the jam.

Jam zones 3-2 and 3-3-1 are the ON jam and OFF jam of the feedout sensor 4 of the duplex tray, respectively, and the reason why these are separate jam zones is that in the case of an ON jam, the jam zone is In the case of an FF jam, the paper is left in the Duplex tray and has not been ejected completely.In the case of an FF jam, the paper has come out of the Duplex tray, but it has not been completely ejected, and in the case of an ON jam. You can pull out the Duplex tray and clear the jam from the top of the tray, but it is OFF.
In the case of a jam, it is necessary to pull out the Duplex tray, open the cover under the tray, and clear the jam from below, and the jam zones are separated because the jam clearing methods are different. By clearing this jam, sensor 4
is turned off.

Jam zone 3-3-2 is an ON jam of the transport sensor 5 of the duplex tray, and is a jam when paper remains in the duplex tray, so it is different from an OFF jam of the sensor 5. It is called a zone. The sensor 5 is turned off by clearing the jam.

Jam zone 3-3-3 is in composite copy mode (COP).
ON jam and O of sensor 11 provided in the duplex tray population when Y ON C0PY)
This is an FF jam, and the jam zone 3-6 is an ON jam and an OFF jam in the composite copy mode of the same sensor 11, and the jam areas are separated, respectively. This is because the method of entering the duplex tray differs depending on whether it is composite copy mode or not, and whether it is entered without inverting or inverting and entering the duplex tray. This is what makes it different as a jam zone.

The sensor 11 is turned off by clearing the jam.

Jam zone 3-4 detects paper ejection from the main body.
Turn on the XIT sensor 10 and the user discharge sensor 9
These are jams and OFF jams, and the jam clearing method is to pull out the user unit to clear both jams, so they are set in the same jam zone. Sensors 9 and 10 are turned off by clearing the jam.

Jam zone 3-5 is an OFF jam of the EXIT sensor of the main body, and depending on whether there is a sorter or not, it is determined whether non-sorting is detected or not, or whether sorting is detected or not. In other words, if there is a sorter, non-sorting can be detected by an ON jam of the non-sort sensor 21, so there is no need to detect an OFF jam by the EXIT sensor of the main body, and when sorting or stacking occurs, it is possible to detect non-sorting by turning on the non-sorting sensor 21 and detecting an OFF jam. Since there is a distance to the main body, the jam in that case is detected by the OFF jam by the EXIT sensor of the main body. Further, if there is no sorter, the sensor 10 performs OFF jam detection. Sensors 9 and 10 are turned off by clearing the jam.

([-7-5) Display Processing Flow FIG. 40 is a diagram showing the display processing flow when jams are prioritized.

FIG. 40(A) shows a processing flow in the case of a dynamic jam.

In the case of dynamic jams, the jam with the highest priority is displayed first, and when that jam is cleared, the jam with the next highest priority is displayed, allowing the user to clear the jam according to the displayed jam. .

In step 1001, it is checked whether there is an input jam, and if there is an input jam, it is displayed, and the display is continued until the input jam is cleared (steps 1002 and 1003). If the input jam is cleared or if there is no input jam, check whether there is an output jam (step 1004).
), similarly display output jams,
If the output jam is cleared or not (steps 1005 and 1006), check whether there is a main body jam (step 1007), and if there is a main body jam, the main body is sequentially operated until all jams are cleared. Jam will be displayed.

FIG. 40(B) is a diagram showing a processing flow when displaying a static jam.

In the case of static jams, the jams with the highest priority are displayed for 5 seconds at a time, so that the priority order and the jam that is occurring can be seen.

Check if there is an input jam, and if there is an input jam, display it for 5 seconds.Step 101
Steps 1 to 1013), when 5 seconds have elapsed, similarly check to see if there is an output jam, and if so, display it for 5 seconds. In this case, the display will be displayed for 5 seconds in the same way, and once that is finished, the input jam will be displayed again, and this will be repeated cyclically thereafter.

〔Effect of the invention〕

As described above, according to the present invention, jams are prioritized and
When multiple jams occur, the Guinamic jams are displayed in order of priority, and when that jam is cleared, the next jam is displayed, so the user can see the displayed jams. You can clear jams efficiently by clearing them one by one.
Furthermore, since all the jams are not displayed on the screen at once as in the conventional case, it is possible to save the display screen and the memory capacity required for this purpose.

In addition, in the case of static jams, the ones with the highest priority are displayed sequentially at predetermined intervals, so you can immediately recognize the order in which they should be cleared and all jams that have occurred, allowing you to respond appropriately. Become.
