Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a display as a user interface to display an original for selecting functions and setting execution conditions, thereby improving the image quality of copiers, facsimile machines, printers, etc. The present invention relates to a recording device for recording information, and particularly to a functionally divided display device with a simplified display screen.

[Conventional technology]

In recent years, with the introduction of computers, recording devices such as copying machines have come to make full use of advanced control technology and data processing technology.As a result, the available functions have become more diverse, and the selection of functions and the setting of conditions for function execution have become more complex. Moreover, various original works are required. For the operator, there are many types of operations to memorize, which makes the operations complicated, making it easy for operators to make operational errors due to differences in operating procedures. Therefore, a console panel is used to make operations as easy as possible for the operator. The console panel is provided with operating means such as various key switches and a numeric keypad for operation selection, and is further provided with an indicator lamp and a display for displaying selections made by key operations, setting states, and operation guidance messages.

Conventional user interfaces are mainly console panels on which keys, LEDs, and liquid crystal displays are arranged, and include, for example, a butterlit type or one with a message display. A back-lift type console panel is a display board on which a fixed message has been placed at a predetermined position, and is made readable by selectively illuminating the display board from behind with a lamp or the like. The attached 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.

FIG. 42 is a diagram showing an example of a console panel employed in a copying machine, which has already been separately proposed by the applicant (e.g., Special Patent No. 62-278653 to Japanese Patent Application No. 62-278655). .

A menue display board 702 is arranged on the upper part of the console panel 701, and the contents of each panel part (703 to 708) are displayed in characters.

Among these, one switch 709 and two indicator lamps 710 are arranged on the sorter panel 703, and it is possible to select the sorting mode (stack mode or collation mode) when the soaker is connected. It looks like this.

The function selection panel 704 includes a switch 711 for editing, correcting, and checking the image, a switch 712 for storing it in the job memory, a continuous page copy function, a border erase function, a margin function, and various other copying forms. A switch 713 for making a copy, a switch 714 for making a double-sided copy, and a display lamp 715 for indicating whether or not these switches are selected are arranged.

On the monochromatic color emphasis panel 705, four display lamps 715 are arranged to indicate the type (color) of the color developer in the container, and four switches 716 to 71 are arranged in the remaining part.
9 and an indicator lamp 710 for indicating which of these switches 716 to 719 is set. These are the marking color switch 716,
These are a partial color conversion switch 717, a snapshot color composition switch 718, and a monochromatic color switch 719.

The copy 4 degree panel 706 includes a display lamp 71O indicating which of the five copy densities has been selected, and a shift key 720 for selecting one of these copy densities.
．． 721 is arranged.

When the upper shift key 720 is pressed, the copy density is set to become lighter, and when the lower shift key 721 is pressed, the copy density is set to become darker. For example, the density can be adjusted in 16 steps. An automatic density adjustment switch 723 is arranged below the copy 4 degree panel 706, and when the switch is operated, the automatic density display lamp 722 lights up to enter the automatic density adjustment mode.

The magnification/paper selection panel 707 has a section on the left side for setting and displaying the magnification, and a section on the right side for setting and displaying the 0 magnification. Shift keys 724 and 725 for setting an arbitrary magnification and a magnification display section 723 are arranged, and next to these are a fixed magnification key 726 for selecting a predetermined fixed magnification, a magnification display board 727, and a display lamp 710.
is located. In the section where you select the copy paper,
Eight types of display boards 728 displaying paper sizes or paper types and shift keys 729 and 730 for selecting one of these are arranged. Further, on the left side of the eight types of display boards 728, a display lamp 710 is arranged to indicate which paper size or paper has been selected. Furthermore, a panel 707 for magnification/paper selection
An automatic paper/magnification selection switch 731 for selecting a preset combination of magnification and paper size is arranged below.

A symbol 732 of this copying machine and a liquid crystal display section 733 are arranged on a display panel 708 located on the right side of the magnification/paper selection panel 707. The pattern 732 displays the selection status of the supply tray, the location of the paper jam, etc. by lighting a lamp, and the liquid crystal display section 733 displays various messages in sentences including kanji, and displays the selection of functions and execution conditions. Make settings.

Furthermore, various keys or buttons are arranged below the display panel 708 as well. These are an all-clear button 734 for returning the copying machine to its basic state, that is, priority mode, and a numeric keypad 735 used for entering numerical values to set the number of copies and specify the diagnosis content when diagnosing the copying machine. , an interrupt button 736 that is used when continuous copying is in progress and it is necessary to make another emergency copy, when stopping the copying process midway through, when setting the number of copies, and when setting the sorter bin. A stop clear button 737 is used as a clear button, a start button 738 is used to start copying, a selection key 739 is used to move the cursor to the message displayed on the liquid crystal display 733, and a These include a setting key 740 for setting.

The console panel described above is arranged so that an area for basic operations such as paper selection and copy density setting, for example, and an area for applied operations such as function selection and monochromatic color enhancement are separated.

In addition, by displaying sentences containing kanji and kana on the liquid crystal display section 733 to assist in advanced operations, an effort is made to reduce the occurrence of errors in panel operations as much as possible.

In the case of a copying machine, the functions that can be selected differ depending on whether or not it is equipped with an additional device such as a sorter, an automatic document feeder capable of reading double-sided originals, an intermediate tray capable of double-sided copying, and an IC card device. come. Naturally, the available functions differ depending on these combinations, so the number of switches placed on the console panel for selecting functions and the processing within the device associated with operation also differ, and the display lamps vary accordingly. The arrangement and number of display devices also differ. Copy machines are increasingly being used in offices.
At the same time, user demands have become more diverse, and there is a strong trend toward higher performance and multifunctionality. In order to improve exploration performance under these circumstances, it is necessary to determine the arrangement and size of keys and displays and change the configuration of the console panel according to the equipment of the additional equipment. Become.

[Problem to be solved by the invention] Recording devices such as copying machines occupy a large proportion of offices, but in a situation where the cost of office space is soaring, it is necessary to use office space efficiently. There is a strong demand for recording devices such as copying machines to be made more compact and occupy a smaller area. However, as mentioned above, when the console panel has more functions, the number of switches and displays to select them and set execution conditions increases, requiring a large space and increasing the size. There is a problem in that it becomes impossible to secure space when attaching. Therefore, when attempting to make a copier or the like more multifunctional and more compact, there is a problem in that there is a limit to how compact the console panel can be made, especially since multifunctionality and compactness conflict with each other in the console panel.

Furthermore, if an attempt is made to make the device compact, multi-functional, and highly recognizable, the console panel must be mounted at a limited position in front of the device due to the ease of construction. Therefore,
On the other hand, if space is limited, the number of switches and displays will have to be reduced, but in this case, the fewer switches and displays will have to be used in combination, making operations and displays more complicated. Put it away. Also, if you try to minimize the number of switches and displays in a limited space, you may end up arranging the switches or displays in a crowded manner or have to use smaller ones. . As a result, there is a problem in that the density of displayed characters on the display increases, and the surface of the console panel becomes complicated.

Therefore, instead of using this type of console panel as a user interface, the applicant adopted a CRT display and set the selection area on the CR7 screen by shaking keys, thereby allowing selection of functions and setting of execution conditions. We have separately proposed a recording device that reduces the number of keys as much as possible.

However, even when using a CRT display,
Providing information compatible with multi-functionality requires a large amount of information, which requires a large display area, making it difficult to support miniaturization. When a compact CRT display is used, it becomes difficult to provide all necessary information on one screen not only due to display density issues, but also because of the need to provide a screen that is easy for the user to view and view.

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems, and it is an object of the present invention to provide a functionally divided display device that employs a screen configuration that is easy to understand and operate even when using a compact CRT display. That is.

[Means to solve the problem]

To this end, the present invention uses a display 02 as a user interface O1 for setting function selection and execution conditions as shown in Fig. It is divided into multiple groups such as frequently used groups and special groups, and the divided I! A selection mode screen 05 is set for each performance group. Then, follow the operator's keyboard 03 manual manual switching instructions for U/
This is characterized in that the divided selection mode screens are switched by the I CPUO 4 and displayed on the display 02, and functions can be selected and execution conditions can be set on each screen.

[Effect]

In the functional division display device of the present invention, a selection mode screen is set and switched for each divided function group, so selection and setting of multiple screens can be performed with a single key, and each selection mode screen can be easily viewed. can be configured. Furthermore, the number of keys installed on the keyboard can be reduced, and an easy-to-use screen tailored to the user can be provided due to the configuration of divided groups.

(1-2) Functions and Features of the System (A) Functions The present invention fully automates the process from entrance to exit of copying operations while providing a wide variety of functions that meet the needs of users. , selection of functions, selection of execution conditions, and other menus are displayed on a CRT display, making it easy for anyone to operate.

Its main function is to categorize the modes into basic copy, advanced copy, and specialized copy by switching the display screen on the CRT display, and display menus for selecting functions and setting execution conditions in each mode. At the same time, it is possible to manually move the cascade of screens to select and specify functions and input execution condition data.

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 and B6 to B3, but also for non-standard paper sizes, and as described earlier, it has a three-stage built-in tray.

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.

The display function uses a CRT display, etc. to provide the operator with information on jams, paper remaining, toner remaining, recovered toner full, user warm-up wait time, 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 adjustment and configuration settings.

Furthermore, as an option, MS
I, HCF, second development colors (red, blue, green, brown), editors, 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) Lower costs In addition to making expensive parts in-house, improving technology and standardizing them, we are also working to reduce art supplies costs by improving the hardware of art supplies and reducing toner consumption.

(c) Improving reliability We aim to reduce component failures and extend lifespan, clarify in/out conditions for each parameter, and identify design defects.
We are aiming to achieve 100kCV nomenclature.

(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. Various mode settings, including copy mode settings, can be selected according to the user's requests. These user interfaces are
This is done using a CRT display and a small number of keys and LEDs arranged around it in correspondence with the west face, making mode setting possible with an easy-to-read display menu and simple operations. Also,
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 predetermined 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 a comparison machine in which the Hass machine 1 shown in FIG. Assume that the copying machine has a highly advanced system configuration. Among the shared users, some persons or departments may require the DADF 13 or sorter 19, while others may 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 insert the IC card into the IC card device and operate the copying machine to remove the DADF 13, the sorter 19, the supply trays (6-1 to 6-3), and the digital copy machine. - The press tray 11 can be used freely, and office efficiency can also be improved. On the other hand, people who do not need to sort copy paper do not have a sorting program.
Cost can be saved by using only 0's.

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

There are multiple copying machines installed in the shop, each of which is equipped with an IC card device 22.Customers request an IC card according to the type of service and use it to select the copying machine of their choice. to make a self-service copy. Customers who are not familiar with copying machines can request an IC card equipped with a program that displays explanations of the work, and by using this card, Ur12 can display various operating information, ensuring that copying operations are carried out without error. be able to.

Whether or not the DADF 13 can be used and whether multicolor recording can be performed can be determined by the lent IC card, and it is also possible to restrict the types of devices that can be used, making it possible to manage customers according to the price. Furthermore, since the actual status of the copying process, such as the number of copies and the size of the copy paper used, can be entered on the IC card, billing becomes easier, and detailed services such as discounts on copying fees for regular customers are also possible. become.

As a third example, we will explain a service that uses an IC card that stores a program for a specific user.0For example, in a patent office, when considering patent publications that have been reduced by photolithography, a copy is made that is the same as the original size. 2 because of necessity
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 an IC card for general use, 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 the LCD display. By pressing this button, only the desired range of the original will be copied, or only the necessary portion will be copied 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.
, CHM subsystem 33.1 MM subsystem 34,
Four subsystems consisting of marking subsystem 35, surrounding U/■ subsystem 36, and INPUT
Subsystem 37.0UTPUT Subsystem 38, O
5 consisting of PT subsystem 39 and installation subsystem 40
It consists of nine subsystems, including one subsystem and one subsystem. Then, for the SQMGR subsystem 32, the CHM subsystem 33 and the 1MM subsystem 34
Since this is executed by software under the main CPU 41 shown in FIG. 4 together with the SQMC;R subsystem 32, the subsystems 1 and 1, which do not require communication, are connected by an interface (shown by 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 is the U/I subsystem 3
Receives copy mode setting information from 6, issues work instructions to each subsystem, and constantly monitors the status of each subsystem while synchronizing each subsystem so that copy work can be performed efficiently. , is a sequence manager that quickly assesses the situation when an abnormality occurs.

The CHM subsystem 33 is a subsystem that controls the paper storage tray, debrax tray, manual feed tray, copy paper feed control, and copy paper barge operation.

The 1MM subsystem 34 is a subsystem that performs panel division on the photosensitive material belt, running/stopping control of the photosensitive material heald, 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, control of repetitive automatic document feeding (RDII),
This is a subsystem that detects the document size.

The 0UTPUT subsystem 37 is a subsystem that controls the sorter and finisher and outputs copies in sorting, stacking, and non-sorting modes, or in a refined 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 belt, erases the leading and trailing edges of images, and erases images according to the editing mode.

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

Here, the main CPU 41 is connected to the main board of the base machine 1 (located on the roof, and includes the SQMGR subsystem 32, CHM
Subsystem 33.1 includes software of the MM subsystem 34, and is connected to each of the CPUs 42 to 47 via a serial bus 53. These CPUs 42 to 47 correspond to each subsystem connected by the serial communication interface shown in FIG. 3 on a one-to-one basis. Serial communication is lo
The omsec@1 communication cycle is performed between the main CPU 41 and each of the other CPUs 42 to 47 according to a predetermined timing. Therefore, for signals that mechanically require strict timing and cannot be matched with the serial communication timing, each CPU is provided with a δ relay input signal (TNT terminal signal), which is connected to a separate hotline from the serial bus 53. Interrupts are handled by the line.

That is, for example, 64 cpm (A4LEF), 309
1. At a process speed of mm/sec. '-I
Make JJ work and improve control accuracy of regigate by ±1
If it is set to mm, jobs that cannot be processed in the communication cycle of 100 m5 e c 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 (i) If the operation control programs for all these additional devices were to be prepared on the base machine, the amount of memory required for this would be enormous. By becoming. Also,(
11) If you develop a new additional device in the future or improve the current one, the ROM (
This is to make it possible to utilize these additional devices without replacing or expanding the read-only memory.

For this reason, the base machine 1 has a basic storage area for controlling the basic parts of the copying machine and an additional storage area tα for storing the program loaded from the IC card together with the functional information of the present invention. The additional storage area includes DADF1
Various programs such as the control program of 3 and the control program of the user interface 12 are stored.

When a predetermined additional device is attached to the base machine 1 and an IC card is set in the IC card device 22, the program necessary for the copying operation is read out through the user interface 12 and loaded into the additional storage device. It has become.

This loaded program controls the copying operation in cooperation with the program written in the basic storage 9M area, or with priority over this program. The memory used here is non-volatile memory consisting of random access memory backed up by batteries. Of course, other storage media such as IC cards, magnetic cards, floppy disks, etc. can also be used as nonvolatile memory. In order to reduce the burden on the operator, this copier can preset settings such as image 4 degrees and magnification, and can store these preset values in non-volatile memory. It has become.

(1-4) Serial communication method Figure 5 is a diagram showing the transfer data structure and transmission timing of serial communication, and Figure 6 is a diagram showing the mutual communication interval in one communication cycle. ~47) Serial communications (3)
Then, data amounts as shown in FIG. 5(a) are allocated to each of them. In the same figure (a), for example, in the case of a user interface, the transmission data TX from the main CPU 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 ti (FIG. 4(C)) 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 m5. 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, based on the communication speed of 96008r'S, the time required to send 1 byte is 1.2m.
S, and the time from when the slave finishes receiving to when it starts transmitting from °ζ is 1 mS, and as a result, 100 m5 is one communication cycle.

(1-5) State division FIG. 7 does not show the state portion υ1 of the main system.

State classification divides the state from power ON to the copy operation and the state after the copy operation is completed, determines the job to be performed in each state, and if all jobs in each state are not completed, the state is transferred to the next state. This is to ensure control performance and accuracy by preventing transitions.A flag is determined corresponding to each state, and each subsystem refers to this flag to ensure controllability and accuracy. Know which state you are in and decide what you 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 the conditions set in NVM.

In the initialization state in the 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, the cork lamp is turned on and the fuser surface is rotated for a predetermined period of time, and when the fuser reaches a predetermined control temperature, the 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 V DDF of the photosensitive material belt are adjusted. Also, the ADF motor is ONI,,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 pinches and panel management is performed until the first panel reaches the get park point. That is, the pinch is determined according to the copy mode, the magnification is notified to the optical subsystem, and the lens is moved. Then, the CHM subsystem and 1MM subsystem are notified of the copy mode, and when the magnification cent is recognized, the scan length is determined based on the magnification and paper size and is notified to 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, finds the first copy panel, and goes to the get park point. When you reach it, you become a Get Park Ready 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 Exposure)
, DDP control, etc., and repeat the copying operation. Then, when R/L=count number of sheets is reached, originals are exchanged, and when this is done for a predetermined number of originals, a coincidence signal is output and the °C 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. Also, if a cycle down factor such as a jam occurs from the set-up or cycle amplifier, a transition is made to cycle down.

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

Held down occurs when a jam occurs on the side of the tray from the tacking point, and by cutting the heddle notch, the belt drive is stopped and the paper beyond the heddle can be ejected.

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

Then, when these belt-down and hard-down factors are removed, it goes into standby! ＞Do.

In the scanning exposure apparatus configured as described above, the exposure method of PIS (Precesso Silane Imaging System) mode and N0N-PIS mode is selected by engaging and releasing the P■S clutch 125. In the PIS mode, for example, when the magnification is 65% or more, the P S clutch 125 is engaged and the second scanning system B is moved at a speed of 2 to move the exposure point of the photosensitive material belt 4 in the opposite direction to the photosensitive material.

FIGS. 11(a) and 11(b) show control of the scan cycle of the optical system, and this control is performed by controlling the first scanning system A at a specified magnification,
It scans at a scan length and starts when a scan start signal is received from the hotline. An image scan count, which is the number of encoder clock counts from the registration sensor interrupt to the end of the scan, is calculated from the scan length data received from the main. First of all,
After setting the reference clock data corresponding to the magnification, the carriage motor is rotated in the scanning direction (CW) in step ■, and acceleration control during scanning is performed (step ■)0
Next, in step (2), PLL (phase control) mode is set, and if there is an interrupt signal indicating that the register sensor is off in step (2), image scanning is started, and when the encoder clock count exceeds the value corresponding to the scan length (step ■), cancel PLL mode, set to speed mode, and move the carriage motor in the return direction (C
CW). Then, in step ■, CW
It is determined whether or not there is an interrupt to the CCW (reverse rotation signal), and if so, acceleration control is performed at the time of return (step ■), and if the encoder count reaches a preset braking start point (step [phase]), performs deceleration control upon return (step ■), and stops the carriage motor if there is a reverse rotation signal again (step @). Also, (b
), set the count number to turn on (open) the shank, open the shutter when the encoder clock count exceeds the shutter-on count, and open the shutter when the encoder clock count exceeds the shutter-off count. Close it to end the image scan.

The area around the Tl-2 bell belt consists of an imaging system and a marking system.

The imaging system is managed by the 1MM subsystem 34, which performs the writing and erasing of 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. 12 is a diagram showing an outline of the belt.

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

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 heald 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). If you do not manage the forming area), 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, and the copy mode and paper specified by the user are set. Decide the number of panels (pitch number) to be placed on the belt according to the size, press the start button, and when the first panel to be copied comes to the getbark position near roll 201, a signal will be issued and copies will be made from there. I try to give a signal that says.

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 period of time before the register (exposure location) 231, a pinch signal is output, and the timing of carriage scan and paper feed is determined based on this signal. The heald surface subjected to 'fF't by the charge corotron 211 is exposed at the exposure point 231. At the exposure location 231, there is a
A light image of the original document is incident on the light source. For this purpose, an exposure lamp 102, a plurality of mirrors 101 to 113 and an optical lens 108 are arranged to transmit the reflected light from the surface of the original illuminated by the exposure lamp 102, among which mirror 101 is used for reading the original. be scanned. Also mirror 1
10.111.113 constitutes the second scanning optical system, which is P I S (Precession Ta+ag
Since there is a limit to increasing the process speed, a second scanning optical system scans in the opposite direction of the belt movement so that the copy speed can be increased without increasing the process speed. The speed for the F eye is increased to achieve a maximum of 64 sheets/rntn (CPM).

A static Ti 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 exposed portion 231 . After erasing unnecessary images, between images, and side erasing with an IEL (Interimage Lamp) 215, the electrostatic latent image is usually transferred to a developing device 2 of black toner.
16 or 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. In addition, since the heald is made of a transparent material, before transfer, a pre-transfer lamp 225 (also used for erasing) irradiates light onto the belt from the back to further weaken the electrical adhesion of the toner, and transfer is performed. make it easier

On the other hand, copy paper stored in the supply tray of the base machine 1 or coffee paper fed manually along the manual feed tray 16 is sent out by a feed roll, guided to a conveyance path 501, and transferred to the organic photosensitive material heald 4. It passes between the transfer corotrons 220. Paper feed is basically 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 material belt 4 are subjected to 'L11' by the strip finger 222 of the detasocorotron 2211, and the coffee paper after transfer is transferred to the heat roll 232 and the pressure roll 2.
33 and is thermally fixed, and then transferred to the transport roll 234.2.
35 and is discharged onto a U output tray (not shown).

The sensitive material heald 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 seven sides by a lamp 225, and unnecessary toner, dust, etc. are removed by a blade 226. scraped off.

Note that patches are formed between images on the belt 4 by a batch generator 212, and the electrostatic potential of the punch 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 heald hole sensor 213 to detect the heald speed and control the process speed. Also A
A DC (Auto DensHy Control) sensor 219 compares the amount of reflected light from the toner on the patch with the amount of reflected light without toner to detect the degree of toner adhesion, and a pop sensor 223 detects the amount of toner adhesion to prevent the paper from peeling off. It detects when it gets wrapped around the belt.

Figure 13 is! This shows how the panels on the heald 4 are worn out.

Since the belt 4 has a seam part 251, an image is not placed there, and a belt hole 252 is provided at a constant pressure 1z from the seam part, for example, with a circumference of 1158a.
In case a, l is 70■. Figure 253.254
are the first and last panels when the photosensitive material belt surface is divided into N pitches, B in the figure is the panel interval, C is the panel length, and D is the panel pitch length.
The distance is 386 mm if the distance is 9°5, divided into 3 pitches, and 579 m if the distance is divided into 2 pitches. Seam 251 connects the LE (Lead Edge) of panel 253 and panel 25.
Set A=B/2 so that it is in the center with the TE (Tail Edge) of 4.

Note that although the panel OLE needs to match the LE of the paper, the TE does not necessarily match, but rather matches the maximum paper TE to which the panel can be applied.

FIG. 14 is a block diagram schematically showing the functions of the 1MM subsystem.

To outline the functions of the 1MM subsystem 34, it performs serial communication with the IEL subsystem 40 via a pass line, and manages image formation by sending a υ1 input signal via a hot line for highly accurate control.
Marking subsystem 35, CHM subsystem 33
The belt is controlled by sending control signals to 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 a low temperature environment, the fuser is rotated idly to maintain the fixing roll at a predetermined temperature so that rapid copying can be performed. and,
When the start key is pressed, the printer enters the setup state, and before copying, constants such as V DDP are adjusted, and when the copy cycle begins, the image is set up based on the original size.
Erase the edges at the leading and trailing edges to form the required image area. A patch is also formed in the inter-image area to form a patch for toner density adjustment. Furthermore, if a hardware down factor such as a jam or belt failure is detected, the heald is stopped or the machine is stopped by communicating with the sequence manager.

Next, the input/output signals and operation of the 1MM subsystem will be explained.

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

An optical registration signal is input from the optical registration sensor 155, which serves as a reference for the PG request signal, bias request signal, and ADC request signal output from the 1MM subsystem to the marking subsystem.

The document size is input from the platen document size sensors S6 to S1.degree., and the area to be erased by the IEL 215 is determined from this and the paper size.

A belt hole signal is manually input from the belt hole sensor 213, and the main motors 264 and 265 control the process speed to correct for variations in the time it takes for the belt to make one revolution.

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, the heald 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 the 17FI hole at a certain time or the size of the hole changes, the IMM will notify the sequence manager of this and the °ζ machine will be stopped.

In addition, the 1MM subsystem is the IEL subsystem 40
It performs serial communication with the PCB, and also sends interrupt signals through the hotline, as well as a position enable signal, an IEL image signal, an ADC patch signal, and an IEL black band signal. The IEL image signal is used to erase unnecessary images, and the ADC patch signal is used by the IEL subsystem 40 to define the shape and area of the patch area formed by the patch generator 212, as well as adjust the amount of charge to create a static image. Adjust the it potential to a constant potential of 500 to 600v. In order to prevent the belt 4 from being scratched by the blade 226, the IEL black band signal forms a black band between images at predetermined intervals to adhere toner and act as a kind of lubricant, especially when the belt 4 is close to a blank sheet. This prevents the belt 4 from being damaged by tJt even when copying when the amount of toner 5t is extremely low, such as in a situation like this.

Furthermore, the rMM communicates with the marking subsystem 35 via a hotline, and sends out a punch formation request signal, a bias request signal, and an ADC request signal based on the optical registration signal. In response to this, the marking subsystem 35 drives the patch generator 212 to form a patch, drives the ESV sensor 214 to detect the electrostatic potential, and also drives the developing devices 216 and 217 to form a toner image. are doing. Also, pre-transfer corotron 218, transfer corotron 220
, controls the drive of the pig corotron 221.

A pitch recent 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.

C) [If it is necessary to send a registration gate trigger signal from the IMM to the M subsystem 33 to control the paper so that the leading edge of the image coincides with the paper at the picking point, and to correct the opening timing of the registration gate, We calculated and sent the corrected product.

Further, the toner scraped off by the blade 226 is collected in a collection toner bottle 268, and a detection signal between the toner particles in the bottle is input to the IMM, and an alarm is issued when a predetermined value 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. 15 shows a timing chart.

The reference time for control is the optical registration sensor position. Predetermined time of optical registration sensor on/off signal (
After T l ), the 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 patch generator request signal (T
5) generates an ADC punch signal to form a patch on the inter-image. After the punch is formed, a bias request signal is issued (after T6) and current (t) is performed, and then an ADC request signal is issued (after T7) to detect the toner density.Also, the black hand signal is used to detect the toner density. The Black Hand is formed.

Note that during AE (Auto Exposure) scanning, °ζ is 0N10FF of the IEL image signal.
will not be carried out.

(II-3) Paper conveyance system In FIG. 16, 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 as an option, a large capacity tray (HCF) 17 is installed on the side.
A manual feed tray (MS) 16 is provided, and each tray is appropriately equipped with a no-paper sensor, a size sensor, a clutch, and the like. 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 feeding of the copy paper 4 is carried out by a specially provided feed motor, and a stencil 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.

The second gate solenoid is different from ordinary solenoids of this type, and controls the gate to open when energized to 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. After that, when the conveyance of the copy paper is resumed at a predetermined timing, the power supply is stopped and the gate is opened. There is little variation in the position of the gate, and even if copy paper is pressed against the gate with a relatively strong force, it can be positioned accurately.

When copying again using the duplex mode that copies on both sides of the paper or the composite mode that copies multiple times on the same side, the paper is guided to the conveyance path that stacks on the duplex tray 11.In the case of the duplex mode, the It is stacked directly onto the duplex tray 11, but in the case of the combination mode, the inverter 10 for the combination mode is first stacked from the conveyance path.
Thereafter, the paper is turned over and guided to the duplex tray 11. 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 II side, and a gate 503 is provided at the branch point leading to the composite mode inverter 10 on the duplex tray 11 side. is a gate 505 for switching the conveyance path
．． Further, a gate 507 is provided at the paper ejection outlet 502 so that the paper can be ejected with the copied side facing up by inverting the paper using a tri-roll inverter.

The upper tray and middle tray can hold approximately 500 sheets of paper1
, A3-B5, Legal, Letter, Special B4.11X17
This tray can accommodate paper sizes of . And the first
As shown in FIG. 7, it has a tray motor 551, and is structured so that when the paper runs out, the tray 552 is turned around. 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. Additionally, 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 1.
This tray can store approximately 100 sheets of paper of the same size as the upper and middle trays.

In FIG. 16, the duplex tray is a tray that can accommodate approximately 50 sheets of paper and the same paper size 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 entrance side conveyance path of the duplex tray 11.
For example, in the case of 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 once guided to the composite mode inverter 10 by the gates 505 and 506, and then reversed and transferred to the feed roll 510 by the gate 506.
, guided to the duplex tray II side. In order to store the paper in the duplex tray 11 and allow it to fall freely to a predetermined edge position, a tray inclination angle of about 17@ to 20' is required for -a. However, in the present invention, since the device is made more compact and the duplex tray 11 is housed in a narrow space, the duplex tray 11 can only be beveled at a maximum of 8 degrees. As shown in Fig. 18, side guides 561 and end guides 562 are provided.In controlling these side guides and end guides, when a 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 several dozen sheets of copy paper. It is often appropriate to purchase the base machine alone.

On the other hand, customers who make a large number of copies or who require complex copying operations often require duplex trays or high-capacity trays. As a means of realizing these various requirements, this copying machine system has a structure that allows each additional device to be easily attached or removed, and some of the additional devices are equipped with an independent CPtJ (central processing bag T1.). We are planning to prepare a system to perform distributed control using multiple CPUs. 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 holds approximately 50 sheets of paper.
This is a tray that can accommodate paper sizes 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, the operator only needs to feed the copy paper preferentially 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, if copy paper is set and fed from the manual feed tray 16, there is a possibility that the feeding will start when a plurality of copy papers are set. To prevent this situation, remove the manual feed tray 1.
I am trying to make the selection G.

In the present invention, compactness is achieved by adopting a configuration in which the nuja roll 513, feed roll 512, and takeaway roll 5ti 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 the paper, thereby performing a pre-registration registration run to align the transfer position and reducing paper feeding variations at the feeder unit. Absorbing. The fed paper is fed to the transfer position of the sensitive material heald 4 via the aligner device 515.

Sz is a paper size sensor that detects the size of the original, Sz is an ejection sensor that detects whether the original has been ejected, and S1□ is an end sensor that detects the end of the cleaning tape 625.

Next, with reference to FIG. 21, 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 you press the start button, 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 conveyance path 611. As a result, the material 2601 passes through the arcuate conveyance path 609 and is pressed against the stop gate 6]5 (■ 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 611, and the original size is detected by sensors S, ~S1°. As the roller 612 moves downward and comes into contact with the driven roller 613, the stop gate 615 moves 1M to open the horizontal conveyance path 611, and the third drive 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
l'), large document feed function (LDC), combiator form feeder (for feeding continuous paper for computers)

Therefore, the document is conveyed to the reversing V9 conveyance path 616, passes through the arcuate conveyance path 609 by the fourth drive roller 617 and the second drive roller 607, and is pressed against the stop boob) 615 (■ 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 drive roller 612, the belt drive roller 619, and the fifth drive roller 622 rotate, and the document is transported to a predetermined position on the platen 2 with its back side facing down, where it is exposed. When the exposure of both sides is completed, the heald drive 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 drive roller 622. ). Therefore, the ejected original is first placed in the original tray 60 with the first side to be copied facing downward.
They will be laminated in the order in which they were laminated in No. 2.

(II-5) Sorter In FIG. 22, the sorter 19 has a sorter body 652 and 20 bins 653 on a movable cart 651. Inside the sorter main body 652, there are a heald drive roller 656 that drives the conveyance heald 655 and its driven roller 6'57.
A chain drive sprocket 660 and its driven sprocket 661 for driving the chain 659 are also provided. These belt driven rollers 6
56 and chain drive sprocket 660 are driven by a single sorter motor 658. Conveyor belt 65

(III) User Interface (U/I)
-1) Advantages and ideas for using a display as a user interface FIG. 25 is a diagram showing how a user interface using a display is installed, and FIG. 26 is a diagram showing the appearance of a user interface using a display.

(A) Features of mounting position The present invention is characterized in that it uses a stand-type display as a 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) 1 as shown in FIG. 25(a). By arranging it at the right corner of the copying machine main body l as shown, the size of the copying machine can be designed without considering the user interface 12, and the apparatus can be made more compact. In addition, in a copying machine, the height of the platen, that is, the height of the device, is designed to be at a comfortable waist height for placing a document, and this height regulates the height of the device. As mentioned earlier, the conventional console panel is mounted on the top surface at the same height, and the display and display section for selecting functions and setting execution conditions are placed at a considerable distance from the eyes. Become. 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. Furthermore, by mounting the display at a height close 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 2224 can be additionally equipped without changing the appearance at all, and at the same time, the display can be attached at a position and height that are easy to see. Furthermore, although the display may be fixed at a predetermined angle, it is of course possible to allow the display to change its 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 that the display screen can be easily moved by the operator as shown in Figure 25 (C). A user interface 12 that is easier to see and operate can be provided by pointing it slightly upward to match the line of sight and to the left as shown in FIG. 25(b), that is, to the upper center (toward the operator's eyes). . This configuration allows the operator to be in the center of the device, especially in compact devices.
You can set documents and operate the user interface without moving.

(B) Features on the surface On the other hand, even when using a display, providing information corresponding to multi-functionality requires a large amount of information, so if you think about it simply, a large display area is required, making it compact This has the aspect that it becomes difficult to respond to changes in the market. With a compact display, you can see all the information you need! Providing information on the J-plane is difficult not only because of the problem of display density, but also because it is difficult to provide a screen that is easy for the operator to see and understand.

Therefore, when a display is adopted as a user interface with the aim of making it more compact, it is necessary to adopt a compact size display and devise ways to control the display in order to balance this. The present invention takes advantage of the fact that the display can adopt a variety of display modes and display controls compared to the LED and liquid crystal displays used in console panels, and is easy to understand even when it is compact in size. We have taken various measures to make the display more compact.

For example, in the user interface of the present invention, the display screen can be switched by classifying the copy modes into basic copy, advanced copy, and specialized copy.

In each mode, menus for selecting functions, setting execution conditions, etc. are displayed, and the cascade (cursor) on the screen can be moved using the keys to specify options and enter execution condition data. 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, both sides of the display can be neatly displayed, and the ease of making the screen can be improved. In this way, in the present invention, the screen is divided, the areas are divided on each screen, brightness adjustment, gray display, and other methods similar to display B are devised, and furthermore, the operation keys and LEDs are carefully matched. The scratching unit has a simple configuration, and the display control, display contents, and scratching input are diversified and simplified, and the problem of making the device more compact and multifunctional is solved.

Based on this idea, the 26th version shows the appearance of a user interface constructed using a CRT display.
It is a diagram. In this example, keys/LED boards are arranged below the CRT display 301 and in front of the right side.

In the selection mode screen, the screen is divided into a plurality of areas, one of which is a selection area, and the selection area is further divided vertically so that each can be selected and set as a cascade area. Therefore, the key /L
On the ED board, there is a cascade key 31 for cascade selection settings at the bottom of the pH range.
Place 9-1 to 319-5 and turn off the selection mode screen.
Mode selection keys 308-310 for changing other keys (302-304, 306, 307, 315-318
) and LEDs (305, 311 to 314) are arranged on the right side. Since the number of keys and LEDs is reduced in this way, and they are arranged beside and below the CRT display 301, the size only needs to be slightly larger than the CRT display 301, providing a compact user interface. be able to.

(I[[-2) Display Screen Configuration The user interface of the present invention makes maximum use of the CRT display and simplifies the key/LED board configuration. In order to make the screen simple and easy to view, and to effectively develop selection settings, confirmation, and message communication functions, we have devised a way to divide the screen.
The screens include the selection mode screen for selecting the copy mode, the review screen for checking the copy mode setting status, the fully automatic screen for copying in standard mode, and the multi-functional copy mode. It is composed of an information screen that provides a screen, and a 1.1iTi screen that appropriately displays the location of a jam when it occurs. Furthermore, the selection mode screen has so many functions that it becomes cumbersome to display on one screen, and some of the functions include not only the most commonly used functions but also specialized functions. It takes 3 minutes or 1 minute depending on the time. Press the mode selection key 30 as appropriate for the screen that has been g++ed for this amount.
8 to 310 can be selected and displayed, and a desired function can be selected and set using each of both sides. Furthermore, by dividing these screens into a selection area, a setting status display area for other modes, a message area, etc., it is possible to accurately convey information to the user according to the operation status. It is composed of

(A) Selection mode both sides FIG. 27 is a diagram for explaining the selection mode screen.

The selection mode screen includes 3ii [j
The screen is set and switched to be displayed on the CRT display by operating the mode selection keys 308 to 310. Of these screens, the basic copy screen groups the most commonly used functions, and the advanced copy screen groups the next most commonly used functions. The specialized copy screen is a grouping of special specialized functions.

The west side of each selection mode is basically used by dividing it into a message area A consisting of two lines from the top, a CJT area B consisting of three lines for displaying the setting status, and a selection HP area C consisting of nine lines. The message area contains a J code message when there is a conflict in the copy execution conditions, a U code message when there is a hardware failure that requires contacting a service person, and a C code message that prompts the operator to perform various notes. sage etc. will be displayed. Among these, the J code message has a check table for combinations of copy execution conditions according to the settings of each cascade, and when the start key 318 is pressed, the table is referred to and changes are made, and if there is a conflict in the copy mode, Output. In the setting status display area B,
The selection status of other modes, for example, the selection status of advanced copy and specialized copy, is displayed on the basic copy screen. In this selection state display, if the cascade state of selection area C is other than the default (lower row), the cascade will be displayed.0 In selection area C, the cascade name is displayed in the upper row, and the cascade name of each cascade region is displayed. The bottom row is Defor 14J.
The iJl area and the iJl area above it are non-default areas, and each of the five cascade areas can be selected by repeating the cascade key. Therefore, if no selection is made, the default area is selected and the default state becomes fully automatic copy mode. In addition, the selection i1 area includes lower cascade keys 319-] to 3 corresponding to the cascade area divided vertically into five areas.
Selection settings are made in step 19-5. The right side of the message area A is used as a count section for displaying the set count and the maid count, and the lower line of the setting status display area B is used as a maintenance information section such as toner bottle full, toner low supply, 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. 27(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 using 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. The 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 9) is from 50% to 200? It can be set arbitrarily in 1% increments up to 50.7%, 70%, 81%, 50.7%, 70%, 81%, etc. 100%
, 121%, 141%, and 200%, and an arbitrary magnification that continuously changes by 1% can be selected.

"Double-sided copy" defaults to one-sided, and other than the default, in the relationship of original → copy, you can select duplex 1 single-sided, duplex → duplex, single-sided → duplex 0 For example, double-sided 1 single-sided is for double-sided original One-sided copying is performed, and one-sided → double-sided copying is used to make a two-sided copy of a single-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. This content setting is done using both pop-up screens.

The default for "sorter" is copy receiving, and collation and stacking can be selected as non-default options. T-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 J,'' ``binding margin,''``color,'' ``interleaf sheet J,'' and ``ejection side,'' as shown in FIG. 27 (b).

"Special originals" include R function (LDC) that copies large originals such as A2/B3, and A function (CF F
; computer form feeder), two of the same size
Dual copy function (2-U) that copies two originals onto one sheet of paper
P) 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 binding can be set to the right or left, and the length of the binding margin can be set to a value 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 OHI' copying, and can be selected other than the default.

The "ejecting surface" can be selected other than the default so that either the front side or the back side is forcibly specified for ejecting the paper.

(C) Specialized Copy The specialized copy screen includes "Job Memory", "W41 Mi/Composition", "Same Size Fine Adjustment", as shown in Figure 27 (C).
It consists of a cascade of "wake erasers".

"Job Memory" is a page program that uses a card, in which multiple jobs are registered and automatically copied by calling them and pressing the start key. , its calling 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. Furthermore, within this function, there is a pop-up screen that allows you to select partial color, partial copy, 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 photo copies the photo to the specified area, and partial deletion prevents the specified area from being copied. With the marking color, when an area to be marked is designated, 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. 28 is a diagram showing an example of a screen other than the selection mode screen.

(B) Review screen The review screen displays the status of the copy mode selected on each of the above selection mode screens that have been cut into three halves, as shown in Figure 28 ())). The cascade setting status of each selection mode screen is displayed on one side. This review z-'fr screen displays the selection items, that is, the cascade salt, and the currently selected mode, that is, the option.If the selected mode is the default, it is displayed in grayback, for example, and if it is not the default, it is displayed. The display is reversed against a background of normal brightness.

By distinguishing between the default state and the non-default state in this way, the options when changing from the fully automatic mode to the non-default state are made to stand out. In addition, the screen configuration is divided into three copy modes: basic copy, advanced copy, and specialized copy, and is displayed in three stages, and this display position corresponds to the position of the mode selection key.
Switching from the review screen to each mode screen is easy to understand. This display allows the operator to check the setting status of each cascade, thereby improving originality and reducing copy errors.

(b) Fully automatic screen The fully automatic screen is a screen like the one shown in FIG.
= When created (released) or all clear key 316
Appears when the crop is dried. Both sides of the cascade of each selection mode screen are all set to defmelt. On this screen, set the original on the platen as instructed, set the number of copies using the numeric keys, and press the start key 318. Paper of the same size as the original will be selected and the set number of copies will be executed.

(C) Information screen The information screen is a double-sided screen that provides explanation screens for how to make copies, etc. for each copy mode as shown in FIG. , by entering the information code displayed on the west side using the numeric keypad, an explanation screen will be displayed.

(d) Jam screen The jam screen is displayed over the screen that was displayed during copying, as shown in Figure 28(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 FIG. 29 is a diagram showing an example of classification of screen layout. As explained in FIGS. 27 and 28, the present invention divides the screen into a plurality of screens and switches to display them, thereby reducing unnecessary information at any given time and converting 100 pages of information into a single column. , these are categorized into, for example, a double-sided layout shown in FIG. In other words, Figure (a) shows the layout of the selection mode screen, Figure αa shows the layout of the review screen, fully automatic screen, edit input screen, job program screen, etc., and Figure (C) shows the layout of the preheating screen, anti-seize screen, and information screen. This is the layout of screens, diagnostic screens, etc.

In the present invention, a screen with accents that is easy to see and understand is constructed by changing the display B according to the display area of these layouts, the input setting state, etc. For example, the selection mode screen with the layout shown in FIG. 29(a) is divided into a message area (including a count area), a setting status display area (including a maintenance information area), and a selection area, as described above. However, the display mode of each area is changed. For example, a message containing a count part aM Jj! In this case, the bank is black and only the message string is displayed in high brightness, and the display is similar to that of a battery lid type console panel, making the display more familiar and easy to understand. Also,
In the setting state display area, the background is displayed as a mesh, that is, dots are displayed in brightness and darkness with a predetermined uniform density, and the display portion of the cascade salt is displayed in reverse (characters are displayed dark and the background is displayed brightly).

In other words, this display represents each cascade salt as a card image, and adds borders to give it a three-dimensional effect and make it easier to understand. 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. The same display format as the message area is adopted so that the message area can be easily recognized. In the selection area, the surrounding area is displayed in a grainy manner, 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, 21 banks of set options are displayed in high brightness (inverted display), and, for example, on the basic copy screen, the option for a tray that has run out of paper in the paper tray cascade is highlighted in black. and set the character to high f
f L'! It is displayed.

The fully automatic duplexing shown in Fig. 28 (ja) results in the screen layout shown in Fig. 29 (b), but on this screen, the background of the display area is set to a dark side, and each rokusaku instruction such as "Set manuscript" is displayed. The displayed CJI area is displayed as a bright split and its boundaries are removed to improve the clarity of the display and make it easier to see.In this way, the display mode of the background can be freely changed and combined as appropriate. Of course, this can be done.

In particular, displaying the background with high brightness (normal brightness with paper white) or displaying the background with reduced brightness,
As shown in the figure, borders of display areas with a predetermined brightness/dark density are bordered to give a visual three-dimensional effect and give the image of a card. By performing border display while changing the display mode of the background of each area in this way, 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 displaying them on a printer, it is possible to call the user's attention to each characteristic of the displayed information.

Furthermore, in addition to devising changes in the brightness of banks and characters in character strings as described in , the present invention also adds icons (pictograms) to choices, cascade salts, and other character strings to create a more imaginative image. It is also distinctive in that it adopts a display mode characterized by the following. For example, on the basic copy screen, the cascade salts "Reduce/Enlarge", "Double-sided copy", "
These include the additions to "Copy Density" and "Sorter", and the additions to the "Paper Tray" options after the bottom, middle, and top paper sizes. This icon conveys information to the user visually from a different perspective, that is, by using an image instead of the accent of information that is provided by a string of characters alone, and depending on the content of the information, it may be more accurate and intuitive than a string of characters. It has a great advantage in that it allows necessary information to be conveyed to the user.

(II+-3) The key/LED board user interface is CR
It is composed of a T display and a key/LED port, but in the present invention, it is particularly configured with a CI? Since the configuration uses the screen of the T display to display options and set them, the keys and L E on the key/LED board
Efforts are being made to keep the number of D's to a minimum.

In other words, as explained earlier, in order to make effective use of the CRT display, the screen displayed on the CRT display is divided into 1□sushi, and each screen is also divided into areas to organize the displayed content and make it easier to see. The screen has been carefully structured. For example, the selection mode screen is divided into three parts: basic copy, advanced copy, and specialized copy.The selection area of each screen is further divided into five cascade areas, and function selection settings can be made in each cascade area. I try to do it. Then, mode selection keys 308 to 310 for screen switching, and cascade keys 319-1 to 319-3 for selecting each cascade area.
19-5 allows functions to be selected and set using eight keys. Therefore, mode selection keys 308 to 31
0 and select either the basic copy screen, advanced copy screen, or specialized copy screen, after that, except for the operation of the cassgate keys 319-1 to 319-5, the numeric keypad 30
It is possible to select all functions simply by inputting numerical values in 7 and execute copying using the desired function. The cascade keys 319-1 to 319-5 are the -L direction movement key and downward movement key, in order to select and set functions by moving the setting cursor up and down in each cascade area. .

In this way, both sides of the selection mode are selected by the mode selection keys 308 to 310 out of the three and only one of them is displayed, so it is difficult to tell which mode selection key 308 to 310 the screen is selected by. LI' and D311 to 313 are used for display. In other words,
When the mode selection keys 308 to 310 are operated to display both sides of the selected mode, the mode selection keys 308 to 310
LP0111 to LP0113 corresponding to 0 are lit.

Having a large number of functions makes it difficult for users to remember and use all of them. Therefore, the information key 302 is used to provide a screen explaining how to make copies for each copy mode.
is used. This information function is executed as follows. First, information key 3
When 02 is operated, a list of information codes is displayed on an information index screen as shown in FIG. 28(C). When the information code designated on this screen is selected and input 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, both sides of the selection mode are divided into three screens, and selection settings for various functions defined on the three screens are performed, so you can check the overall setting status including the other sides. You are also required to do so. Therefore, the review key 303 should be used to check the full screen setting state. This review key 303 is a key for displaying a review screen. When this key is pressed, a review screen as shown in Fig. .

One screen will be displayed.

The dual language key 304 is a key for switching the language of the display screen. Due to internationalization, devices are often shared by users who use various different languages. Even in such an environment, in order to prevent language problems, 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. , it is possible to output the display screen by freely switching between Japanese and English.In addition, it is possible to output the display screen not only in two languages but also in multiple languages, and to switch the languages in a predetermined order by operating the dual language key 304. You may also add Japanese dialects.

The preheating key 306 is used to set a preheating mode in order to save power consumption when not in use and to enable a quick transition from the not in use state to a copy operation. Switch between preheating mode and fully automatic mode using the yoke. 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. 28(a).

The interrupt key 315 is a key used when continuous copying is in progress and there is a need to make another copy, and when the interrupt processing is finished, it is used to return to the original copying operation. The interrupt is also canceled. LP0
Reference numeral 114 indicates whether the cut key 315 is in an interrupt state or in a state where 8V is removed.

The stop key 317 is used to stop copying in the middle, to set the number of copies, and to set the bins of the sorter.

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

(III-4) User interface control 1ffll
System configuration Figure 30 shows the relationship between the U/I CPU and the main CPU connected via serial communication, Figure 31 shows the hardware configuration of the user interface, and Figure 32 shows the software configuration of the user interface. A diagram showing
FIG. 33 is a diagram for explaining screen switching control.

(A) Hardware configuration The main CPU 41 has a ROM 32 as shown in FIG.
3. NvRAM (non-1'F generation/-EIJ) 324, Ink 7E that exchanges data with the Heas machine X32
1. Has an interface 322 for exchanging data with an additional device (OP74ON), the bus is connected to a communication control circuit 327 via a bus arbiter 326, and the U/T is connected on a serial communication line through the communication control circuit 327.
It is configured to communicate with the CPU 4G and other CPUs. The ROM 323 stores programs including subsystems such as the sequence manager, imaging module, and copy handling module described above. The bus arbiter 326 has a system RAM 325, holds data sent from the main CPU 41 to other CPUs, and data received from other CPUs, and enables the main CPU 41 to send and receive data asynchronously with the timing of serial communication. J? 0M3213 stores a communication program that causes the communication control circuit 327 to transmit and receive data over a serial communication line. Note that the main CPU 41 may be configured to perform all functions related to communication such as those of the bus arbiter 326 and the communication control circuit 327. The sequence manager subsystem in the main CPU 41 monitors the status of each subsystem through the serial communication 3, and when it receives a copy mode signal from the user interface, the sequence manager subsystem in the main CPU 41 monitors the status of each subsystem so that it can perform copying operations efficiently at a predetermined timing. Give work instructions to the system.

The user interface system equipped with the U/I CPU 46 basically consists of a CRT 5 temporary 331 and a CRT display 301 as hardware, as shown in FIG.
and a key/LED board 333. and,
The CRTI board 331 is a U/I CP that centrally controls the entire
U46, a CRT controller 335 that controls the CRT display 301, a keyboard/display controller 336 that controls the key/LED board 333, and further includes a program memory (ROM) 337 that stores the above programs as a memory, and a program memory (ROM) 337 that stores frame data. A frame memory (ROM) 338 is used to store tables, display control data, etc., and a RAM 3 is used as a work area.
3'], 2 sets (7) V-RAM (T?AM for Hiteo
) 340, a k+'y vector generator 342, and the like.

Main CPU41 and CRT base F1.331 U/1 c
Between the PU 46, the driver 344 and the receiver 343
Data is sent and received via a serial communication line. TXD is the transmission signal from the CRT5 board 331,
RXD is a received signal to the CRTd temporary 331. For example, a 11.0592 MHz crystal oscillator is used as the clock generator 346, and by dividing this into 1/12 inside the U/I CPU 46, the frequency of the crystal oscillator is 0.9216 MHz.
The fundamental frequency of lI2 is generated. In the communication of the CPU 46 for U/1, this is set to 1 to 2 by an internal timer.
Transfer lock is set by dividing the frequency by 56 (programmable). Therefore, the fundamental frequency is 0.9216M
Decide to divide Hz into 173 by program, and then divide it by 1/3.
When divided by 2, the transfer lock becomes 9600 TIz (transmission bit rate is 9600 BPS).

The ULT CPU 46 receives the state signal of the main CPU 41 and the machine, and also inputs the operation signal of the key/LED board 333 from the keyboard/display controller 336 to switch the screen displayed on the CRT display 301 and set the copy mode. , generates a message to be displayed on the CRT display 301. and,
When the start key 318 is operated in the input processing of the operation signal of the key/LED board 333, the copy mode at that time is checked, and if there is no contradiction, the main CPU 4
If there is a conflict in the copy mode, a J code message is generated and displayed on the CRT display 301. In the display processing of the CRT display 301, a character generator code is set corresponding to the display screen, and the code is written into the V-RAM 340. The frame memory 338 stores information for setting the coat of the character generator. When a code is written to the V-RAM 340, the character generator 3 is written in synchronization with the task address under the control of the CRT controller 335.
42 don't data is read out, and the parallel/direct conversion circuit 35
5, it is converted to serial data and displayed on the CRT display 3.
01 is displayed.

Watchdog timer (W, D, T) 345 is U/1
This is to check whether the cPU 46 runs out of control, and if the U/I CPU 46 is located at a specific address, for example data area 7000.
It is reset when any address from ~77FF is read. Therefore, by creating a program to read this specific address within 150m5, the U
If the /r CPU 46 goes out of control, the specific address will not be read even after 150m5 has passed and the watchtong timer (W, D, T) 345 will not be reset.
Processing for the I CPU 46J% run is performed.

The keyboard/display controller 336
Clock generator 34 inputting to IJICT'U46
The output of 6 is divided by 1/4 by the counter 347 to 2.76.
A key/LED scan time of 4.98 m5 is created by inputting a 48 MHz clock and further dividing the frequency by 1/27 to 102 kHz using a prescaler.

Since this scan time requires a long time to detect input, there is a problem that input data is not captured when the operator's key press time is short, and conversely, if it is too short, the CPU This will reduce the number of recircuits that operate frequently. 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 human power management, double-sided output management functions, and functions such as job management, control, selection judgment, mode determination, etc. It consists of a job controller with a And regarding key human power, 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 performs screen control using machine status information, selection mode information, etc., and issues interface commands to the video controller.The video controller then executes the commands, editing the west side,
Perform tX drawing. Note that the key change detection section 3 described below
62. Blocks that process, generate, and control other data are each shown in a certain program middle level (module), and these structural units are summarized for convenience of explanation, and there are further Of course, it may be constructed from a plurality of modules, or may be constructed from a plurality of modules all at once.

In the video controller, the key change detection section 362 performs a double press check or one continuous key press state detection on the physical key information detected 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 double-sided 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, in the screen switching section 36th, the logical key to expand the pop-up screen is stored as a table, and if the logical key is original and there is no other key human power within 750m5ec, the pop-up screen will be expanded. Display control data 367 is updated. This process prevents both sides of the pop-up screen from being expanded at once in some cases where the option to expand the pop-up screen is temporarily selected by operating the cascade key during the selection process of a certain option. This is done for the purpose of Therefore, even if it is a logical key that opens a pop-up screen, 7
If there are other key personnel within 50m5ec, -
This will be ignored as a temporary key human resource. In addition, in the case of updating the state such as the occurrence of a jam, updating the cohering mode such as moving the cascade, or updating the message or count value, the display control unit 369 receives an interface command from the job controller, analyzes it, and controls the display. Data 367 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 37ρ has the basic frame of each screen,
It is a one-story 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 data section 366 reads out the basic frame and display data of the screen to be displayed from the dialog data 370 based on the screen number to be displayed in the display control data 367.
Furthermore, regarding variable data, the display data is determined according to the display variable information of the display control data 367, the screen is tied up, and the display screen is drawn and developed in the V-RAM 365.

In the job controller, the key management unit 14 refers to the state table 371 to check whether the logical key is currently in an acceptable state. 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 37
7 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 the interface routine (display control section 369). State management section 372
is a state table 3 for key acceptance by determining state changes from machine status information such as key acceptance status, occurrence of jam or fail, and open interlock.
Update 71. The state table 371 is set with job state, machine state, run case, constate, state case, mode information, etc.
For example, the job state includes whether the job is a normal job or an interrupt job, whether the job is running or has finished, whether it is in duplex mode, etc., and the machine state includes initialization, progress, soft down, etc. States such as coin, soft downbose, purge, standby, purge standby, jam, etc. are set, and the state of each of the above states is recorded in the run case. Then, the key acceptance conditions are checked based on these state information. After the original start key is pressed, the job control unit 376 controls the fh of the machine.
It receives the production information, issues commands for machine control, and performs management for executing a copy operation for one original document. The command control unit 373 notifies the state management unit 372 and the zip control unit 376 of the status of the received command sent from the main body, and also controls the job control unit 376 during job execution.
It receives the command for execution from and sends it to the main unit. Therefore, the start key is exhausted and the key control unit 375 is activated to send the command 'c Send 4' corresponding to the copy mode.
When a copy operation is executed by setting the 3-bit sofa 380, commands regarding the operating status of the machine are sequentially received by the receiving sofa 379. The command control unit 373 sends this command to the job control unit 37.
6, a command to execute the next copy 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. During the 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 sends the command from the display management section 377 to the video controller through the key control section 375. Issue interface commands for jam screen control.

In the interface command, as a registration command,
For example, regarding the tray, there are Nα, paper size, orientation, additional device: device name, presence/absence, second development, presence/absence, color, etc., and normal setting commands include cascade, cascade, set number of sheets, binding margin, etc. Edit setting commands include box display, 1 display, etc. Job setting commands include recall values, registered values, etc. Display commands include C1 normal message, state display, maid display, remaining toner display, collected toner display,
The remote commands include jam, jam clear, information change, preheat, interrupt, return, change, etc., such as no paper display. Broadly speaking, there are display control commands, machine tlJ operation status commands, initialization commands, diagnostic commands, etc. The display control unit 369 of the video controller analyzes these commands and updates the display control data 367. For example, the registration command performs initial settings for each screen, and the normal setting command displays the cascade setting status on the west side of the normal setting, deletes unnecessary cascades, displays the set number (set count), and displays the margin value. In the mode conversion command, each mode screen display and LED
(not shown) is turned on/off.

With the cascade key operation as described above, when the cascade key is turned from on to off, the 750m5
When ec is continued to be pressed, when 125 m5 ec continues to be pressed, the corresponding key is moved by one rank if it is accepted. If the mode cannot be accepted at the destination, one rank is skipped and the next key is selected. In this operation, when the cascade is up, the corresponding logic code is passed to the job controller as a key reception, and is fed back from the job controller to the video controller as display data.

The screen changes are triggered by the conditions shown in FIG. 33, respectively. First, when the power is turned on and initialization is completed, the basic copy screen is displayed unless there is an instruction to shift to the diagnosis mode. This basic copy screen is displayed by creating an all clear key, basic copy mode selection key, and preheating key at the preheating screen.Advanced copy duplex, specialized copying screen, and review screen are displayed using each mode selection key. The display can be switched depending on the operation. The start key is accepted only on these screens, and the copy operation can be executed. In addition, in the specialized copy double-sided screen, when an Ifi or job program is selected, the screen changes to the manual screen, and when the input is completed, the original specialized copy west side screen is displayed. Furthermore, when operating the information key from these screens and inputting the code, the screen shifts to the information screen, and when the preheating key (power save key) is operated, the screen shifts to the preheating screen.

If a jam occurs, the jam screen is superimposed on the selected mote screen at the time of copy execution. If any of the above-mentioned screens remain on the screen and there is no key input after a predetermined period of time, the anti-burning screen will be switched to by the operation of a timer, and will return to the original double-sided screen by key operation.

Next, an example of processing corresponding to operator operations and machine conditions will be described.

First, when the TL source is turned on and initialized, the state table 371 is in the initial state and the key management unit 374 sends the first F1 to the screen switching unit 368 on the condition that there is no key input.
Give instructions for one screen. In the video controller, in response to this instruction, the screen switching unit 368 changes the display control data 36
Make the display screen of 7 the initial screen.

If the initial screen is set as the basic copy screen in the display control data 367, the dialog editing unit 366 reads the basic copy frame from the dialog data 370. This frame includes display control data 36 for each area.
Since the address of 7 is shown, dialog editing section 3
Display control data 367 based on this address by 6G
is read out and edited, and a basic copy screen is drawn in the V-RAM 365. At the same time, the basic copy LED is lit. Here, the keyboard's applied copy, specialized copy mode
When the AK key is pressed, the key management unit 374 checks the key acceptance conditions and similarly issues a corresponding double-sided instruction to the screen switching unit 368. Note that the display control data 36
If the initial screen is set to be fully automatic in step 7, the fully automatic screen will be set to (1).This setting is performed in the diagnosis mode.

When the physical key table 361 is updated by operating the cascade key C in these double-sided display states, the key change detection section 361 detects this, and the key conversion section 363 converts it into a logical key. Since the conversion of a cascade key to a logical key differs depending on the screen, the conversion to a logical key is performed by controlling the reference position of the conversion table 364 based on the screen information of the display control data 367. For example, when the cascade key 19-3 is operated in FIG. 26, if the screen is the basic copy screen shown in FIG. 27(a), it is converted to a logical key for double-sided copy cascade; The applied copy screen shown in b) is converted to a color cascade logical key.

The key management unit 374 determines from the state table 371 whether or not acceptance is currently possible, and in this case, accepts the key on the condition that it is a cascade key on the selection mode screen. From here, it is sent to the state management section 372. Key control section 3
In step 75, the copy mode 378 is updated from this key, and the cascade display information is passed to the display management section 377, and an interface command is generated in display ffFffl 1377 and issued to the display control section 369. The display control unit 369 receives this interface command and updates the cascade setting information of the display control data 367.

As described above, this content is thereafter reflected on the screen by the dialog collection unit 366. In this way, when each selected mode is switched to both sides and each cascade is set, the setting status will be displayed on the display screen, and the copy mode 3 of the job controller will be displayed.
78, the state table 371 is updated.

Then, when one start key is created, the key control section 375 executes a copy mode 378 and issues a copy execution command. This copy execution command is issued by setting it in the transmission buffer 380, and is transmitted by the monitor to the main CPU via a serial communication line. If the mode settings are inconsistent, the display management unit 377 generates and issues a display control interface command to control the message.

Upon issuing the copy execution command, the job control unit 376 manages the copy operation for each copy. For example, when the machine starts a copy operation and machine status commands are constantly received in the reception buffer 379, the command control unit 373 analyzes them and notifies the state management unit 372 and job control unit 376. The job control unit 376 receives the machine status command and issues commands necessary for machine operation for each copy up to a set number of copies. This is the command control section 3
73 to the transmit buffer 380. On the other hand, the state management unit 372 updates the state table 371 according to this machine state command. Therefore, in this state, the key management unit 374 is no longer permitted to accept mode selection keys, cascade keys, etc.

When a jam occurs during copy execution and a jam occurrence command 4 is received from the machine, the information is passed through the command control section 373 to the job control section 376 and state management section 372. As a result, the state table 371 is updated with the jam occurrence state.2. , ;Shizo is interrupted. The key control unit 375 recognizes the jam occurrence position and passes the information to the display management unit 377, and the display management unit 377 provides an interface with jam zone parameters added, for example, by mode classification and jam processing coat. Generate and issue commands. Then, the second display control unit 369 processes this command and updates the display control data 367 to the contents of the jammed C side display, thereby lowering the brightness of the screen at that time by one rank and displaying the jam zone on the screen shown as 13. The pressed jam screen will appear on the display.

In addition, with machine status commands, the key control unit 375 recognizes the remaining toner, the collection bottle status, paper out, ink tank open, etc., and displays the message area, maintenance information QH6N area, count area, etc. through the display management unit 377. Take control.

Diagnosis mode is entered by, for example, turning on ta and simultaneously pressing the all clear key in a special manner. This mode is also recognized by the key control section 375 through the key management section 374. Then, a diagnostic command is issued through the display management unit 377 to control the GUI game screen f711. In this mode,
The specific 9R range of the display control data 367 can be registered and set, but cannot be set in normal modes other than the diagnosis mode. For example, setting whether to display a fully automatic screen or not to display a fully automatic screen is one of them.

(C) Key/LED and display display control No. 34
FIG. 21 is a diagram showing an example of a keyboard scan setting map, FIG. 34(b) is a diagram showing an example of an LED scan setting map, and FIG. 35 is a diagram showing display timing.

The keys/LEDs are controlled by the keyboard/display controller 336 from the 102 kHz clock as previously described. ! A scan time of 18 m5ec is created for processing, and in that scan, as shown in Figure 34 (a), one cycle consists of 8 scans from "0" to "7", and each scan is made from "0" to "7". 17'' is used to generate the physical table described earlier.

Similarly, the LED is also controlled on/off by a scan map as shown in FIG. 34jb).

The CRT display 301 is, for example, 9 inches in size, has a paper white display color, and has been subjected to a non-glare surface treatment.

Using a screen of this size, the total number of dots is 480 x 240 in a display area of 160 mm x 110 mm, and the number of pixels is 0.
．． If the size is 33mm x 0.46mm and the dot configuration of the tiles (characters) is 8 x 16, the number of tiles will be 60 x 15. Therefore, the kanji kana is 16 do soto x 16 do soto,
When alphanumeric characters and symbols are displayed using 8 dots x 16 dots, 30 x 15 characters can be displayed using two tiles. In addition, four gradations of normal brightness, gray 11 gray 2, and black level are specified for each tile, and displays such as reverse and plink are also performed. Input 13 for such a display
The signal timing is the dot frequency f.

Assuming that the frequency is 10MHz and 480x240, the period of the horizontal synchronization signal is 64μs, which is 48II as shown in Figure 35.
The video data is processed for 15.36 m5 with the period of the vertical synchronization signal of 16.90 m5.

The clock generation circuit 353 generates a clock at the frequency of the dots output from the parallel/direct conversion circuit 355, and uses the counters 35 and 4 to generate a clock at the character generator 342.
The frequency is divided into the Sit extraction period of the parallel dot data read from. Therefore, according to the output clock of the counter 354, a plurality of bits of dot data are input from the character generator 342 to the parallel/direct [19] circuit 355, which converts it into real data and sends it to the attribute adding circuit 356. The attribute adding circuit 356 receives the blanking signal from the CRT controller 335 and controls the video signal according to the attribute data only during the display period.

Further, the one-shot circuit 348 uses a vertical synchronization blanking signal among the blanking signals output from the CRT controller 335 to output i#? of the U/T CPU 46. This is to generate a 1-input signal.

Figure 36 is a diagram showing an example of V-RAM address correspondence;
Figure 7 is a diagram showing the correspondence between the first V-RAM address and the CRT display position, Figure 38 is a diagram for explaining the readout circuit of the character generator, and Figure 39 is a diagram showing the dot pattern, data, and scan address. It is a figure showing a corresponding example.

The video data loaded into the V-RAM 340 consists of 16 bits per tile, of which 12 bits are used to represent the character generator code, and the remaining 4 bits are used to represent attributes. Therefore, V-
1'? The AM340 stores the character generator code in correspondence with the address on the CR7 screen, and the lower 8 bits are stored in RAM.
-1, 4 bits of the tens place and 4 bits of the attribute are RAM-
It is configured so that it can be written to H, and holds two screens worth of these.

The address of the V-RAM 340 is independently managed by the U/I CPU 4G and the CRT controller 335, as shown in FIG. The display on the CRT display 301 is performed by the CRT controller 335.
Do it with For example, il? V from CRT controller 335
- Looking at the address of the RAM 340, it becomes as shown in FIG. 37, and the code and attributes of the character generator are written into addresses "0", "1", . . . , respectively. Therefore, the CRT controller 335
The circuit shown in Figure 8 synchronizes with the display timing and outputs data rDO-"D7" (example L) at the corresponding address, rDo→
While reading D4J (H side), raster address rR
A, and accessing the character generator generates the scanline data of each tile ``DO
→D7. is output to the parallel/direct conversion circuit 355. for example"
The dot pattern of the kanji for `` wealth'' can be expressed as shown in Figure 39, but as mentioned earlier, the kanji consists of two tiles, so the dot pattern on the left side corresponds to the scan address ``rAo-+A3''. Output rDo → D7 with half as tiles
", followed by the output rDO → D7. with the right half as a tile.
becomes the output of the character generator 341.

Note that 4-bit attributes are also read out in response to the output of this tile, and FIG. 40 is a diagram showing an example of the configuration of a video signal control circuit according to the attribute data. As shown in this figure, attribute control is performed by logically processing the video data and reverse signal attribute data using an EXOR circuit, inverting the video data when the reverse signal is on (high level), and then applying the output to an AND circuit. If the blink signal is on by processing, it may be turned on/off using a clock and the signal level may be changed using a gray signal. As explained earlier on the selection mode screen, the method is changed to clearly display the divided 9■ area or the H1 area of interest such as the cascade position, but as a method to do so, Gray display and reverse display are used by controlling attributes. Furthermore, for example, the 28th
As shown in Figure (a), the display mode of the back H by dots is controlled by the dot pattern of the tiles.

In other words, in Figure 28 (a) "Hara 11 Hescent"
, "Number of sheets set" and "Start" should be displayed at the beginning? The appearance of the scene and the background outside it is changed by changing the dot density of the tiles.

As described above, the video signal displayed on the CR7 screen can be generated by switching between the 177th) V-RAM and the 2nd (7) V-RAM by dynamically changing the start address of the CRT controller 335. Select and read out and display. For that purpose, U/I
The CPU 4 G uses a port for inputting a blanking start signal and a display period signal, and a port for outputting a display permission signal. And CPU for U/I
At step 46, the blanking start signal causes the blanking to occur at the falling edge at the start of the blanking period of the CRT, and the display period signal recognizes the CRT display state.

Further, the display permission signal instructs permission or prohibition of display on the CRT.

(IF-5) Function Selection Execution Process FIG. 41 is a diagram for explaining the overall process flow up to the start of the copy operation. First, an overview of the entire process from turning on the power switch to starting the copy operation will be explained with reference to FIG.

When the power switch is turned on, the initial duplex (fully automatic duplex) shown in Fig. 28(a) is displayed, and the next key input is waited.
Determine the content of the operation. Here, if there is an input on the numeric keypad 307, it is determined that this is an input to set the number of copies for full automatic copying at the same size, and the copy mode and its execution conditions are transmitted to the main CPU 41 by operating the start key 318. As a result, the main CPU 41 controls the start of the copying operation, and starts the copying operation for the set number of sheets.

In the initial double-sided mode, if there is an input from the mode selection keys (303 to 31O) instead of the numeric keypad 307, the key is either the mode selection key 310 for convex copy, the mode selection key 309 for advanced copy, or the mode selection key 309 for Atsumu copy. The corresponding selection mode screen is switched and displayed depending on whether the mode selection key 30B is pressed.

Then, the cascade setting process is performed using the cascade keys 319-1 to 319-5 until the setting of each cascade is completed on the ESS Sawamote screen, and then it is determined whether there is another mode selection input, If there is another mode selection, mode selection and cascade setting processing are performed in the same way. If there is no mode selection and there is an input on the numeric keypad 307, it is determined whether the number of copies has been input, and the copy mode and its execution conditions are transmitted to the main CPU 41 by operating the start key 318. As a result, the main CPU 41 controls the start of the copying operation, and starts the copying operation for the set number of sheets.

Note that the present invention is not limited to the above embodiments, and various modifications are possible. For example, in the above embodiment, a CRT display is used as the user interface, but a plasma display, an F, L display, an overnight display, a fluorescent display tube, or the like may be used, or a touch panel may be further provided. Although the location was set at the back right corner, it may also be placed at the back left corner. Also, CR
By controlling display B on T-display, we have created an accented display, but you may also use a color display to create a color change, or move the selected mote screen from the top to the message area. , the setting status display area, and the selection area have an area of 2; .

Furthermore, although the mode selection keys are arranged in correspondence with the number of divided screens, it may be configured such that switching between both sides is performed using only one mode selection key. ] As is clear from the above description, according to the present invention, the recording '! of a copying machine, etc. Since the selection screen is constructed by dividing the R function of the A position, it is possible to secure sufficient display space for each function selection information, and it is possible to display icons (pictograms), large characters, pop-up screens, etc. , the machine fm selection information can be displayed in an easy-to-read manner. For example, the selection mode is divided into multiple screens in consideration of usage sensitivity, etc., and displayed in an easy-to-read screen configuration, so a compact CRT of about 9 inches can be used as a user interface, making it inexpensive and compact. can provide a user interface. Moreover, minutes! Even when displaying the first screen, a display area for the setting status of other screens is provided on the west side so that necessary information can be displayed so that the overall setting status can be understood, and the setting status of each screen can be reviewed. By displaying a list on the L screen, the setting status can be confirmed with the negative eye, improving operability and reducing copy errors. In addition, the screen is divided and switched and displayed, and functions can be selected and execution conditions can be set on both sides, so simply by arranging the keys necessary for inputting input on one screen, the operation of each screen can be done manually. This makes it possible to make the keyboard configuration simple. Furthermore, by changing the display mode depending on whether the setting position is the default or not, it becomes easier to perform setting states other than the default.
