Description

Description: TECHNICAL FIELD The present invention relates to a full stack control device for a recording device, and more particularly, to a full stack control device that does not display an unnecessary message and at an appropriate timing according to the situation. The present invention relates to a full stack control device of a recording device capable of displaying a message.

[Conventional technology]

2. Description of the Related Art In recent years, recording apparatuses such as copiers have been using advanced control technology and data processing technology with the introduction of computers, and available functions have been diversified. 1: 1 copy,
In addition to the main functions such as reduction, enlargement, copy density selection, and double-sided copying, for example, even if the original is placed on the platen, the user manually puts it on the platen, semi-automatic document feed (SADF) Method or automatic document feed (ADF). The discharge of copy sheets includes a non-sort mode, a sort mode, and a stack mode. In accordance with such diversification of functions, there are many types of condition settings such as function selection or function setting, and various operations are required. In addition, for troubles such as paper jam and running out of copy paper,
In order to cover a wide variety of occurrences and locations, detailed messages for status display and operation guidance are required.

As one of the status display / operation guide messages relating to the copy paper discharge section, there is a full stack message displayed when all sorter bins have been used. As described above, the copy paper discharge mode includes a non-sort mode, a sort mode, and a stack mode.
Among them, the non-sort mode uses only the output tray, and the sort mode sets the number of copies within the prepared number of bins (total number of installed sorters, for example, 20 bins or 40 bins) in advance. It does not exceed the total number of bins, and therefore does not require a full stack message. However, in the stack mode in which one copy of a document is stored in one bin, copy sheets are sequentially stored from the first bin. For example, when the total number of bins in the sorter is 20, the 20th copy There is a problem that the 20th bin, that is, all the bins are used at the time of copying the original, and if the 21st original is subsequently copied, the bin for discharging cannot be secured. Therefore, the conventional full stack controller detects a full stack when ejecting a specified number of copy sheets to the last bin, and stops the machine operation, for example, "Remove the sheets". And then start again "etc. is displayed on the console panel or the like. Thereby, the user can recognize that all bins are used, and can take out the copy paper from the sorter and copy again based on the displayed contents.

[Problems to be solved by the invention]

However, according to the conventional full stack controller, when the last bin is used, the full stack message is unconditionally displayed.For example, when copying 20 originals, the 20th bin is displayed. The copy operation ends normally when the specified number of copy sheets are ejected, but at the same time, by using the 20th bin, a full stack is detected and a full stack message is displayed. However, there is a problem that a user may be confused by the display of an unnecessary message that is not appropriate, and a miscopy may occur. In addition, the determination as to whether the copying operation is in progress or finished when the last bin is used depends on the number of originals and the method of placing the originals, so that the user is not confused. Moreover, there is a problem that it is difficult to display a necessary message at an appropriate timing.

It is an object of the present invention to provide a full stack control device for a recording device, which does not display unnecessary messages that confuse the user and improves operability.

Another object of the present invention is to provide a full stack control device for a recording device, which is capable of displaying a full stack message at an appropriate timing according to the situation.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention provides a display based on the copy mode information and the copy operation end state by the determination means when the detection means detects that the copy sheets have been discharged to all the bins. (EN) A full stack control device for a recording device, which determines whether or not it should be made, and displays or does not display the full stack message on the display means based on the determination result.

That is, the full stack controller of the recording apparatus of the present invention includes the following means.

(1) Detecting means When a predetermined number of copy sheets have been discharged to all the bins (full stack state), a full stack detection signal is output, and the copy operation is continued based on whether or not the copy operation is continued. Output the detection signal.

(2) Judgment means When the full stack detection signal and the copy continuation detection signal are input, display judgment is performed based on the copy mode information. Specifically, it is determined based on the copy mode information whether or not the stack mode is set. Further, it is judged whether the copying is in progress or the copying is completed by the copy continuation detection signal. This detection is performed based on the remaining uncopied document in the ADF device, the placement on the platen by manual copying, the turning on of the start button, or the like. The combination of these determination results determines whether or not to display the full stack message.

(3) Control means The display means is controlled based on the display judgment to display the full stack message.

[Action]

In the full stack control device of the recording apparatus of the present invention, a full stack state in which copy sheets are discharged to all the bins,
When the detection means detects the copy continuation state in which the copy operation continues, the judgment means checks the copy mode, and for example, makes a display judgment such as "no message is displayed" and "displays a message". Based on this, the control means causes the display means to display. As a result, unnecessary messages are not displayed, and full stack messages are displayed at an appropriate timing according to the situation.

(I-2) Function and Features of System (A) Function The present invention fully automates the operation from the entrance to the exit of the copying operation while providing various functions corresponding to the needs of the user. The main feature is that the selection of functions, the selection of execution conditions, and the display of other menus and the like are performed on the CRT display, so that anyone can easily operate.

The main function is to switch the display screen on the CRT display to categorize into basic copy, applied copy and specialty copy modes, and to display menus such as function selection and execution condition settings in each mode. At the same time, the cascade of the screen is moved by key input to select and designate a function, and to input execution condition data.

The functions of the copying machine to which the present invention is applied include a main function, an automatic function, an additional function, a display function, a diagnostic function, and the like.

The main functions include the standard paper sizes A6 to A2 and B6 to B3, as well as the non-standard sizes, and the three-stage built-in tray as described above. In addition, 7 steps of fixed magnification and arbitrary magnification adjustment in 1% increments, and between 99% and 101%, 0.15

There are a job program that calls and processes jobs one by one, a slip sheet that inserts blank sheets one by one between copies, and a center eraser / frame eraser that is used for a book.

The display function uses a CRT display etc. to provide the operator with information on jam display, paper remaining amount display, toner remaining amount display, collected toner full display, fuser warm-up wait time display, inconsistency in function selection and machine status. There are functions such as message display.

The diagnostic functions include NVRAM initialization, input check, output check, history files such as the number of jams and the number of paper feeds, adjustment of initial values used for process codes around marking and photosensitive material belts, and registration on timing. There are functions such as adjustment and configuration setting.

Further, optionally, MS as described above
I, HCF, second deve colors (red, blue, green, brown), editor, etc. can be equipped as appropriate.

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

(B) Achieving power saving A 1.5kVA high-speed, high-performance copier has been realized. Therefore, a control method for achieving 1.5 kVA in each operation mode is determined, and power distribution by function for setting a target value is determined. In addition, an energy system table for determining the energy transfer path is created, and management and verification by the energy system are performed.

(B) Cost reduction The in-house production of high-priced parts and technical improvement and standardization are being pursued. At the same time, the art material life has been improved from the hardware side and the toner consumption has been reduced to reduce the cost of the art material.

(C) Improvement of reliability We are aiming to achieve 100kCV no-maintenance by reducing failure of parts and prolonging service life, clarifying in / out conditions of each parameter, reducing design defects.

(D) Achieving high image quality The present apparatus employs a method in which toner particles are made fine by using microcarriers made of ferrite, and development is performed by using a repulsive magnetic field. As the photoreceptor, a high-sensitivity panchromatic organic light-sensitive material belt formed by coating the organic light-sensitive material in multiple layers is adopted, and a halftone can be expressed by a pictorial mode utilizing a set point. As a result, the generation copy has been improved and the black spot has been reduced, and an unprecedented high image quality has been achieved.

(E) Improved operability A fully automatic mode in which copying is performed in a predetermined mode by operating the start key just by setting the original and entering the number of copies, and a screen divided into basic copy, applied copy, and specialized copy The user can select various mode settings including a copy mode setting according to the user's request. These user interfaces are performed using a CRT display and a few keys and LEDs arranged in correspondence with the screen around the CRT display, making it possible to set the mode with an easy-to-read display menu and simple operations. Also,
By preliminarily storing the copy mode and its execution conditions in a nonvolatile memory or an IC card, it is possible to automate a predetermined operation.

(C) Example of Differentiation In a copying machine to which the present invention is applied, the function 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 for each card, it is possible to differentiate the use of the copying machine. This will be described with some easy-to-understand examples.

As a first example, a multi-purpose building is provided with a copier shared by a plurality of companies, or a copier shared by different departments even within one company or factory. The case will be described. The latter joint use is necessary for budget control, and in the past, use control of each department was performed using a device such as a copy riser.

This copier has an IC card device, a DADF 13, a sorter 19, and a user interface on the base machine 1 shown in FIG.
It is assumed that the copying machine has a relatively advanced system configuration including the supply trays (6-1 to 6-3) 12, and the duplex tray 11. Some co-users require the DADF 13 or sorter 19, while others do not require any additional equipment.

If a plurality of persons or departments having different usage modes try to determine the cost burden of the copying machine solely from their own copy volumes, those who only make low-volume copies will be required to make copies with various additional devices. This would oppose the introduction of the copier, making it difficult to coordinate with people or departments that want to use the copier to a high degree.

In such a case, prepare an IC card according to the usage mode of each person or each department, and the person or department wishing for advanced functions will bear a lot of basic costs,
You should be able to use many functions. For example, the owner of the most advanced IC card operates the copier with the IC card set in the IC card device, thereby obtaining the DADF 13, the sorter 19, and the supply tray (6-1).
6-3) and the duplex tray 11 can be used freely, and office efficiency can be improved. On the other hand, those who do not need copy paper sorting have ICs that lack a program for sorting.
By setting a card and using only the catch tray 20, costs can be reduced.

As a second example, a case where a copy agency runs a self-copy service shop with an IC card will be described.

In the store, a plurality of copying machines are arranged, and an IC card device 22 is attached to each of them. The customer requests an IC card according to the service mode, sets it in a desired copying machine, and makes a copy by self-service. Customers who are unfamiliar with copiers can request an IC card equipped with a display function for operating instructions as a program, and by setting this, it is possible to display various operation information on the U112, so that copying work can be executed without fail it can. Whether the DADF 13 can be used, whether multi-color printing can be performed, and the like can be determined by the IC card to be lent, and the type of use can be limited, so that customers who are charged can be managed. Furthermore, since the actual copy operation such as the number of copies and the size of the used copy paper can be written on the IC card, billing becomes easy, and detailed services such as discounting copy fees to regular customers are also possible. .

As a third example, a service using an IC card storing a program for a specific user will be described. For example, at a patent office, when examining patent publications reduced by photoengraving, it is necessary to make the same copy as the original size.
There are jobs that make copies at a relatively large enlargement rate of 0%. Also, when preparing a drawing to be submitted to a government office, work to reduce or enlarge the original drawing in small steps is performed to meet the request. In addition, in the department that copies the resident's card, such as the city hall or the ward office, copy the image information of the places that are not covered by the request and the image information of the places that should be kept secret to protect the privacy of individuals. And make an abstract.

As described above, some users (users) request to use the copying machine in a special use mode. If the functions of the copying machine are set so as to satisfy all such requirements, the console panel becomes complicated and the ROM inside the copying machine becomes large. Therefore, by preparing an IC card for each specific user and setting the IC card, a copying machine having a function most suitable for the user can be realized.

For example, in the case of a patent office, by purchasing a dedicated IC card, in addition to the fixed reduction ratio of several types, a fixed ratio of 20
The user can easily select a reduction ratio of 0%. Further, it becomes possible to set the reduction ratio in steps of 1%, for example, in a range that requires fine adjustment. In addition, the resident card issuance department can indicate the type of resident card and the fields and items to be deleted on the display such as the liquid crystal display by operating keys such as numeric keys, and then the start button is pressed. By pressing, only the desired range of the original is copied, or only the necessary portion is edited and recorded.

(I-3) Configuration of Electric System Control System of Copying Machine FIG. 3 is a diagram showing a configuration of a subsystem of the copying machine to which the present invention is applied, and FIG. 4 is a diagram showing a hardware configuration by a CPU.

As shown in FIG. 3, the copier system to which the present invention is applied includes four subsystems including a SQMGR subsystem 32, a CHM subsystem 33, an IMM subsystem 34, and a marking subsystem 35 on a main board 31. , U / around it
It is composed of nine subsystems including five subsystems including an I subsystem 36, an INPUT subsystem 37, an OUTPUT subsystem 38, an OPT subsystem 39, and an IEL subsystem 40. Then, for the SQMGR subsystem 32, the CHM subsystem 33 and the IMM subsystem 34
Since it is executed by software under the main CPU 41 shown in FIG. 4 together with the R subsystem 32, it is connected by an interface between subsystems (represented by solid lines) which does not require communication. However, other subsystems are
Since it is executed by software under the CPU separate from 1, it is connected by a serial communication interface (shown by dotted lines). Next, these subsystems will be described briefly.

The SQMGR subsystem 32 receives the copy mode setting information from the U / I subsystem 36, and synchronizes the subsystems so that the copy operation can be performed efficiently,
It is a sequence manager that issues work instructions to each subsystem, constantly monitors the status of each subsystem, and performs prompt status determination processing when an abnormality occurs.

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

The IMM subsystem 34 is divided into panels on the photosensitive belt,
It is a subsystem that controls the running / stop of the photosensitive material belt, the control of the main motor, and other controls around the photosensitive material belt.

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

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

The INPUT subsystem 37 includes automatic document feed (DADF), semi-automatic document feed (SADF), large size (A2) document feed (LDC), computer form document feed (CFF),
This is a subsystem for controlling the automatic feed (2-UP) of the original, controlling the automatic repetition of the original (RDH), and detecting the original size.

The OUTPUT subsystem 37 is a subsystem that controls a sorter and a finisher, outputs a copy in each mode of sorting, stacking, and non-sorting, and performs binding output.

The OPT subsystem 39 is a subsystem that controls scanning, lens movement, shutter, and PIS / NON-PIS when exposing a document, and moves the carriage in the 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 the images, and erases images according to the edit mode.

The above-described system is configured with seven CPUs shown in FIG. 4 as a core, and can flexibly cope with a combination of the base machine 1 and additional devices surrounding the base machine.
Here, the main CPU 41 is on the main board of the base machine 1 and has the SQMGR subsystem 32, the CHM subsystem 33,
It includes software of the IMM subsystem 34 and is connected to each of the CPUs 42 to 47 via the serial bus 53. These CPUs 42-47
Correspond one-to-one with each subsystem connected by the serial communication interface shown in FIG. Serial communication is performed between the main CPU 41 and each of the other CPUs 42 to 47 according to a predetermined timing with 100 msec as one communication cycle. Therefore, for signals that require strict timing mechanically and cannot be synchronized with the timing of serial communication, an interrupt port (INT terminal signal) is provided in each CPU and interrupts are issued by a hot line separate from the serial bus 53. It is processed. That is, for example, a copy operation is performed at a process speed of 309 mm / sec at 64 cpm (A4LEF), and
If it is set to 1 mm, there are jobs that cannot be processed in the communication cycle of 100 msec as described above. A hotline is required to guarantee the execution of such a job.

Accordingly, in this copier, various types of additional devices can be attached, and software can also adopt a system configuration corresponding to each of these additional devices.

One of the reasons for adopting such a configuration is that (i) if the operation control programs for all these additional devices are prepared in the base machine 1, the memory capacity required for this is enormous. It depends. Also,
(Ii) When a new additional device is developed in the future or the current additional device is improved, the ROM (read only memory) in the base machine 1 is not replaced or expanded.
This is because these additional devices can be used.

For this reason, the base machine 1 has a basic storage area for controlling the basic part of the copying machine and an additional storage area for storing a program fetched together with the function information of the present invention, which is composed of an IC card. Various programs such as a control program for the DADF 13 and a control program for the user interface 12 are stored in the additional storage area. Then, when the IC card is set in the IC card device 22 with a predetermined additional device attached to the base machine 1,
A program required for the copying operation is read out through the user interface 12 and loaded into the additional storage device. The loaded program controls the copy operation in cooperation with the program written in the basic storage area or with a priority over the program. The memory used here is a nonvolatile memory composed of a random access memory backed up by a battery. Of course, other storage media such as an IC card, a magnetic card, and a floppy disk can be used as the nonvolatile memory. In this copier, in order to reduce the burden on the operator of the operation, it is possible to preset the density and magnification of the image, and the preset values are stored in a non-volatile memory. ing.

(I-4) Serial Communication System FIG. 5 is a diagram showing a transfer data structure and transmission timing of serial communication, and FIG. 6 is a time chart showing a mutual communication interval in one communication cycle.

In the serial communication performed between the main CPU 41 and each of the CPUs (42 to 47), a data amount as shown in FIG. In FIG. 9A, for example, in the case of the 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, ie, the optical CPU 45
It shows that the transmission timing t _i ((c) in the figure is 26 mS. According to this example, the total communication amount is 86 bytes, and at the communication speed of 9600 BPS, the cycle is about 100 mS.
The data length includes a header, a command, and data as shown in FIG. When the transmission / reception with the maximum data length shown in FIG. 6A is targeted, the entire communication cycle is as shown in FIG.
Here, from the communication speed of 9600 BPS, the time required for transmission of one byte is set to 1.2 ms, the time from the end of reception of the slave to the start of transmission is set to 1 ms, and as a result, 100 ms
Is one communication cycle.

(I-5) State Division FIG. 7 is a diagram showing state division of the main system.

The state division divides the state after the power ON from the copy operation and the state after the copy operation into several parts, decides the job to be performed in each state, and moves to the next state if all the jobs in each state are not completed In order to improve the efficiency and accuracy of control by avoiding this, a flag is determined for each state, and each subsystem refers to this flag to determine which state the main system Know what to do and judge what to do. Each subsystem is also divided into states, and a flag is similarly determined corresponding to each state. The main system refers to the flag and grasps and manages the state of each subsystem.

First, when the power is turned on, the state of the processor is initialized, and it is determined whether the mode is the diagnostic mode or the user mode (copy mode). The diagnostic mode is a mode used by a service person for repairs and the like, and performs various tests based on the conditions set in the NVM.

In the initialization state in the user mode, the initialization is performed according to the contents of the NVM. For example, the carriage is set at the home position, the lens is set at a position of 100% magnification, and an initialization command is issued to each subsystem. When the initialization ends, the state transits to standby.

Standby is a state until all subsystems have completed the initial setting and the start button is pressed,
Display "Please wait" on the fully automatic screen. Then, the Colt lamp is turned on and the fuser idles for a predetermined time, and when the fuser reaches a predetermined control temperature, the U /
I will display the message "Can be copied" in the message. This standby state is a period of about several tens of seconds at the first power ON.

The setup is a preparatory state of copying in which the start button is pressed and started, and the main motor and the sorter motor are driven to adjust the constants such as the _{VDP of the} photosensitive material belt. Also, the ADF motor is turned on, the first document feed starts, the first document reaches the registration gate, and the document size is detected.
The magnification is determined and the ADF manuscript is laid on the platen. Then, the second document of the ADF is sent out to the registration gate, and the state shifts to cycle-up.

Cycle-up is a state where the belt is divided into several pitches and panel management is performed, and the first panel reaches the get park point. That is, the pitch is determined in accordance with the copy mode, and the optical subsystem is informed of the magnification and the lens is moved. Then, the copy mode is notified to the CHM subsystem and the IMM subsystem,
When the magnification set is recognized, the scan length is determined by the magnification and the paper size, and the optical subsystem is notified. Then, the copy mode is notified to the marking subsystem, and when the start of the marking subsystem is completed, the panel L / E determined by the pitch is checked by the IMM subsystem, and the first copy panel is found, and is set at the get park point. When it reaches, it becomes get park ready and enters the cycle.

The cycle is a copy operation, and the ADC (Automatic D
The copy operation is repeatedly performed while performing ensity control), AE (Automatic Exposure), DDP control, and the like.
When R / L = counted number of sheets, document exchange is performed, and when this is performed for a predetermined number of sheets, a coincidence signal is output and the cycle starts.

Cycle down is a state in which the carriage scan, paper feed, etc. are completed and the copy operation is cleaned up.Each corotron, developing machine, etc. are turned off, and the panel next to the last used panel stops at the stop park position. Panel management to ensure that only specific panels are used and do not cause fatigue.

From this cycle down, it usually returns to standby,
If the start key is pressed again when copying in the platen mode, the process returns to the setup in the case of restart. Also, transition from setup and cycle up to cycle down such as a jam occurrence occurs.

Purging is a state in which a jam has occurred, and when the cause jam sheet is removed, other sheets are automatically discharged. Normally, when a jam occurs, the state transitions from any state to cycle down → standby → purge. Then, a transition is made to standby or set-up due to the purge end, but if a jam occurs again, a transition is made to cycle down.

The belt-down occurs when a jam occurs on the tray side from the tacking point. In a state where the belt drive is stopped by releasing the belt clutch, the paper before the belt can be discharged.

The 24V power supply is cut off in a state where the interlock is opened and a dangerous state occurs or a machine clock failure occurs and the control becomes uncontrollable.

Then, when these belt down and hard down factors are removed, the state shifts to standby.

B is fixed and the PIS lock switch 132 is turned on.

In the scanning exposure apparatus configured as described above, the PIS (precession imaging system) mode and the NON-PIS mode exposure method are selected by the engagement release of the PIS clutch 125. PIS mode is, for example, P when 65% or more
By connecting the IS clutch 125 and moving the second scanning system B at the speed V ₂ , the exposure point of the photosensitive material belt 4 is moved in the direction opposite to the photosensitive material, and the scanning speed V ₁ of the optical system is set to the process speed.

As shown in FIG. 9A, the lens 108 has a lens carriage 135 disposed below the platen glass 2.
Is slidably attached to a support shaft 136 fixed to the support shaft 136. The lens 108 is connected to the lens motor Z137 by a wire (not shown), and the rotation of the lens motor Z137 moves the lens 108 in the Z direction (vertical direction in the figure) along the support shaft 136 to change the magnification. Let it. The lens carriage 135 is slidably mounted on a support shaft 139 on the base side and connected to a lens motor X140 by a wire (not shown). The rotation of the lens motor X140 causes the lens carriage 135 to support the lens carriage 135. The magnification is changed by moving in the X direction (horizontal direction in the figure) along 139. These lens motors 137 and 140 are four-phase stepping motors. When the lens carriage 135 moves, the small gear 142 provided on the lens carriage 135 rotates along the cloud surface of the lens cam 143, whereby the large gear 144 rotates, and the second gear of the second scanning system is rotated via the wire cable 145. The mounting base 146 is moved. Therefore, the distance between the lens 108 and the second scanning system B can be set for a predetermined magnification by the rotation of the lens motor X140.

FIG. 10 is a block diagram showing an outline of a subsystem of the optical system. Optical CPU 45 is the main CPU
41 and connected by serial communication and hot line,
In order to form a latent image on the photosensitive material in the copy mode transmitted from the main CPU 41, each carriage, lens, and the like are controlled. The control power supply 152 includes logic (5 V), analog (± 15 V), solenoid, and clutch (24 V), and the motor power supply 153 is configured with 38 V.

The carriage registration sensor 155 is arranged so as to correspond to the registration position of the first mirror 101, and outputs a signal when the actuator attached to the first scanning system A depresses the carriage sensor 155. This signal is an optical CPU45

Reference numeral 25 denotes a type in which the clutch is released when the power is supplied and the clutch is engaged when the power is not supplied, which contributes to 1.5 KVA by reducing the power consumption in the PIS mode.

FIGS. 11 (a) and 11 (b) show the control of the scan cycle of the optical system.
It scans with the scan length, and it starts when a scan start signal is received from the hot line. From the scan length data received from the main, an image scan count, which is the count number of the encoder clock from the interruption of the registration sensor to the end of the scan, is calculated. First,
After setting the reference clock data corresponding to the magnification, the carriage motor is rotated in the scanning direction (CW) in a step to perform acceleration control during scanning (step). Next, in a step, a PLL (phase control) mode is set. If there is an interrupt signal for turning off the registration sensor in the step, an image scan is started. Release the PLL mode, set the speed mode, and rotate the carriage motor in the return direction (CCW). Then, in step CW to CCW
It is judged whether or not there is an interrupt to the (reverse rotation signal), and if there is, acceleration control at the time of return is performed (step), and if the count number of the encoder reaches the preset brake start point (step), return When the reverse rotation signal is received again, the carriage motor is stopped. (Step). Further, as shown in (b), the count number for turning on (opening) the shutter is set, and if the encoder clock number is equal to or more than the shutter on count, the shutter is opened, and the encoder clock number is equal to or more than the shutter off count. If this happens, the shutter is closed and the image scan ends.

(II-2) Belt rotation The belt rotation consists of an imaging system and a marking system.

The imaging system is managed by the IMM subsystem 34, and writes and deletes a latent image. The marking system is managed by a marking subsystem 35, and performs charging, exposure, surface potential detection, development, transfer, and the like. In the present invention, the IMM subsystem 34 and the marking subsystem 34 cooperate with each other in order to achieve high-speed copying and high image quality by performing panel management on the belt, patch formation, etc. as described below. doing.

 FIG. 12 is a diagram showing an outline of a belt periphery.

An organic photosensitive material belt 4 is arranged in the base machine 1. Since the organic photosensitive material belt forms the photosensitive material by coating the charge generating layer, the transfer layer, etc. on many layers, the degree of freedom is greater than the photosensitive drum which forms the photosensitive material by depositing Se,
Since the manufacturing is easy, the cost can be reduced, and the space around the belt can be increased, thereby facilitating the layout.

On the other hand, the belt expands and contracts, and the diameter of the roll also changes due to the temperature difference.Therefore, a belt hole is provided at a fixed distance from the belt seam, this is detected, and a pulse corresponding to the rotation speed of the main motor is detected. Is generated by an encoder to form a machine clock, and a machine clock for one round is constantly counted, so that a pitch signal and a registration timing, which serve as a reference for starting the carriage, are corrected in accordance with expansion and contraction of the belt.

The organic photosensitive material belt 4 in this device has a length of 1 m or more, and is designed to carry four A4 size sheets and three A3 size sheets, but since the belt has seams, it is always a panel (image formed on the belt). (Formation area) If you do not manage it, you cannot make a copy of the specified panel. Therefore, the position of the panel is determined based on the belt hole provided at a fixed distance from the seam, the number of panels (pitch number) to be placed on the belt is determined according to the copy mode specified by the user, and the paper size. A signal is issued when the panel that first makes a copy by pressing the button comes to the position of the get park near the roll 201, and gives a signal that a copy can be made from here.

Organic photosensitive material belt 4 is charged corotron (charger) 21
1 is uniformly charged, and is driven at a constant speed in the clockwise direction in the figure. When the first panel comes a fixed time before the register (exposed portion) 231, a pitch signal is output, and the timing of carriage scanning and paper feed is set based on this pitch signal. Charge Corotron 21
The belt surface charged by 1 is exposed at an exposure location 231. A light image of a document placed on the platen glass 2 arranged on the upper surface of the base machine 1 is incident on the exposure location 231. For this purpose, an exposure lamp 102, a plurality of mirrors 101 to 113 for transmitting reflected light of the document surface illuminated by the lamp, and an optical lens 108 are arranged, of which the mirror 101 is used for reading the document. Be scanned. The mirrors 110, 111, and 113 constitute a second scanning optical system, which is called a PIS (Precession Image Scan). Since there is a limit in increasing the process speed, copy without increasing the process speed. In order to increase the speed, a second
Scan the scanning optics to increase the relative speed, up to 64
/ min (CPM).

An electrostatic latent image corresponding to the document is formed on the organic photosensitive material belt 4 by the image information exposed in a slit shape at the exposure portion 231. And IEL (Inter Image Lamp) 215
After performing unnecessary erasing between images and erasing between images and side erasing, the electrostatic latent image is developed by a developing device 216 for a normal black toner or a developing device 217 for a color toner to form a toner image. The toner image moves with the rotation of the organic photosensitive material belt 4, and is transferred to a pre-transfer corotron (transfer device) 21.
8. Pass near the transfer corotron 220. The pre-transfer corotron 218 is usually for weakening the electric adhesion of the toner by applying an alternating current to facilitate the movement of the toner. Also, since the belt is formed of a transparent material, the belt is illuminated with light from the back with a pre-transfer lamp 225 (also used for erasing) before transfer, further weakening the electrical adhesion of the toner and transferring. Make it easier.

On the other hand, the copy paper accommodated in the supply tray of the base machine 1 or the copy paper manually fed along the manual feed tray 16 is sent out by a feed roll, guided by the conveyance path 501, and Pass between Transfer Corotron 220. The paper feed is basically performed by LEF (Long Edge Feed), and the registration gate is opened and closed so that the leading edge of the paper coincides with the exposure start position at the tacking point, and the toner image is transferred onto the copy paper. Then, the paper and the photosensitive material belt 4 are peeled off by the detack corotron 221 and the strip finger 222, and the copy paper after the transfer passes through the space between the heat roll 232 and the pressure roll 233 and is thermally fixed. And is discharged onto a discharge tray (not shown).

The photosensitive material belt 4 from which the copy paper has been peeled is easily cleaned by the pre-clean corotron 224, and the lamp 2
Unnecessary charges are erased by light irradiation from the back surface by the blade 25, and unnecessary toner, dust, and the like are scraped off by the blade 226.

A patch is formed between the images on the belt 4 by the patch generator 212, and the electrostatic potential of the patch portion is detected by the ESV sensor 214 to adjust the density. Also belt 4
Has a hole as described above, and the belt speed is detected by the belt hole sensor 213 to detect the belt speed and control the process speed. ADC (Aut
o Density Control) sensor 219 compares the amount of light reflected from the toner on the patch part with the amount of light reflected from the toner to detect the toner adhesion level, and pop sensor 223 detects the amount of toner on the belt without peeling the paper. The case where it has been wrapped around 4 is detected.

FIG. 13 shows how the panel is divided on the photosensitive material belt 4.

Since the belt 4 has a seam portion 251, an image is not placed on the belt portion 251. A belt hole 252 is provided at a position at a fixed distance l from the seam portion. For example, when the circumference is 1158 mm, l is 70 mm. . 253 and 254 in the figure are the first and last panels when the photosensitive material belt surface is divided into N pitches.
Is the panel interval, C is the panel length, and D is the panel pitch length, which is 289.5 mm for 4-pitch division, 386 mm for 3-pitch division, and 579 mm for 2-pitch division.
Seam 251 consists of LE (Lead Edge) on panel 253 and panel 254
A = B / 2 so as to be at the center with the TE (Tail Edge).

Note that the LE of the panel needs to match the LE of the paper, but the TE does not always match, and matches the maximum paper TE applicable to the panel.

FIG. 14 is a block diagram showing an outline of functions of the IMM subsystem.

An outline of the function of the IMM subsystem 34 is that serial communication is performed with the IEL difference 40 and the bus line, and an interrupt signal is sent by the hot line to control the image formation for high-precision control. , Sends a control signal to the CHM subsystem 33 to control the belt rotation.

In addition, the main motor is controlled by detecting a hole opened in the organic photosensitive material belt 4, and a panel formation position is determined to perform panel management. In a low-temperature environment, the fuser is rotated idle to maintain the fixing roll at a predetermined temperature so that quick copying can be performed. Then, when the start key is pressed, the setup state is entered, the constants such as V _DDP are adjusted prior to copying, and when the copy cycle starts, the leading edge and trailing edge of the image are erased based on the original size and necessary. Form an image area. Further, a patch for toner density adjustment is formed by forming a patch in the inter-image area. Further jam factors,
When a hard-down factor such as belt failure is detected,
Stops the belt or stops the machine by communicating with the sequence manager.

Next, input / output signals and operations of the IMM subsystem will be described.

A detection signal of the toner in the black toner bottle 261 and the color toner bottle 262 is input, and the remaining amount of the toner is detected.

From the optical registration sensor 155, a PG request signal output from the IMM subsystem to the merging subsystem, a bias request signal, and an optical registration signal serving as a reference of the ADC request signal are input.

The original size is input from the platen original size sensors S _{6 to} S ₁₀ , and the erase area by the IEL 215 is determined from this and the paper size.

A belt hole signal is input from the belt hole sensor 213, and the process speed is controlled by the main motors 264 and 265 to correct for variations in the time the belt makes one revolution. Two main motors are provided so that they can be operated at an efficient operating point, the power of the motor can be efficiently output according to the load condition, and the effective use of the power and the stop position accuracy are improved. Regenerative braking by motor. Also, the motor can perform reverse drive. This is because if cleaning is performed by bringing the blade into close contact with the photosensitive material belt, paper dust and toner residue accumulate on the front side of the blade, and this is removed. Belt clutch 267
And only the belt can be selectively stopped. A pulse is generated from the encoder in synchronization with the rotation of the motor, and the pulse is used as a machine clock to obtain a machine clock corresponding to the belt speed.

If a hole cannot be detected for a predetermined time by the belt hole sensor 213 or the size of the hole has changed, this is transmitted from the IMM to the sequence manager and the machine is stopped.

Further, the IMM subsystem performs serial communication with the IEL subsystem 40, sends an interrupt signal through a hot line, and sends out an IEL enable signal, an IEL image signal, an ADC patch signal, and an IEL black band signal. Unnecessary images are erased using the IEL image signal, and A
The DC patch signal allows the IEL subsystem 40 to define the shape and area of the patch area formed by the patch generator 212 and adjust the charge amount to adjust the electrostatic potential to 500 to 600V.
Adjust to a constant potential. The IEL black band signal forms a black band between images at predetermined intervals so that toner adheres to the belt 4 so that the belt 4 is not damaged by the blade 226, and acts as a kind of lubricant. When the amount of toner is extremely small as in the state, the belt 4 is prevented from being damaged even in the case of copying.

Further, the IMM communicates with the marking subsystem 35 via a hot line, and a patch formation request signal, a bias request signal, an AD
Send a C request 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 an electrostatic potential, and drives the developers 216 and 217 to form a toner image. doing. Further, it controls the drive of the pre-transfer corotron 218, the transfer corotron 220, and the detack corotron 221.

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

A detection signal as to whether or not the color developing unit is mounted is input to detect whether the toner of the developing unit is black or color.

A registration gate trigger signal is sent from the IMM to the CHM subsystem 33 to control so that the sheet and the leading edge of the image coincide at the tacking point, and when it is necessary to correct the timing of opening the registration gate, the correction amount is set. Calculated and sent.

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

The IMM drives the fan motor 263 to prevent an abnormal temperature rise, so that the environmental temperature is within the allowable temperature range and a copy of stable image quality can be obtained.

 FIG. 15 shows a timing chart.

The reference time for the control is the position of the optical registration sensor. The IEL is turned off after a predetermined time (T1) of the optical registration sensor ON / OFF signal. That is, the front end is turned on until T1 and the rear end is turned on after T2. In this manner, the image is formed by the IEL image signal, and the leading edge of the sheet at the tacking point is made to coincide with the leading edge of the image by controlling the timing of the registration gate. After the image formation is completed, an ADC patch signal is generated by a patch generator request signal (T5 after the reference time), and a patch is formed on the inter image. After the patch is formed, a bias request signal is issued (after T6) to perform development, and then an ADC request signal is issued (after T7) to detect toner density. Also, a black band is formed in the inter image by the black band signal.

During AE (Auto Exposure) scanning, I
Does not turn on / off the EL image signal.

(II-3) Paper Conveying System In FIG. 16, as the paper trays, upper tray 6-1 and
The middle tray 6-2, the lower tray 6-3, and the duplex tray 11 are installed in the base machine, and a large capacity tray (HCF) 17 and a manual tray (MSI) 16 are optionally installed on the side. A paperless sensor, a size sensor, a clutch and the like are appropriately provided. Here, the no-paper sensor is a sensor for detecting the presence or absence of copy paper in the supply tray,
The size sensor is a sensor for determining the size of the copy paper stored in the tray. The clutch is a component for controlling on / off of driving of each paper feed roll. In this way, by allowing copy paper of the same size to be set in a plurality of supply trays, when one copy tray runs out of copy paper, copy paper of the same size is automatically fed from another supply tray. .

The feeding of copy sheets is performed by a dedicated feed motor, and a step motor is used as the feed motor. Whether or not the copy sheet is normally fed is detected by the feed sensor. A gate solenoid is used for registration for aligning the leading edge of the copy sheet once sent. This gate solenoid normally performs control such that the gate is opened and a copy sheet is allowed to pass when electricity is supplied differently from this type of solenoid. Therefore, in a standby state in which no copy paper arrives, power is not supplied to the gate solenoid, and the gate is kept open to reduce power consumption. The gate solenoid is energized slightly before the arrival of the copy sheet, and the gate is closed to prevent passage. Thereafter, when the conveyance of the copy sheet is restarted at a predetermined timing, the power supply is stopped and the gate is opened. By performing such control, the position of the gate at the time when the leading edge of the copy sheet is blocked from passing is reduced, and even when the copy sheet is pressed against the gate with a relatively strong force, the positioning of the gate is determined. Can be done accurately.

When copying again in the duplex mode in which copying is performed on both sides of the paper or the composite mode in which copying is performed multiple times on
The sheet is guided to a transport path stacked on the duplex tray 11. In the case of the duplex mode, the sheets are stacked directly on the duplex tray 11 from the transport path.In the case of the composite mode, however, the sheet is temporarily transported from the transport path to the inverter 10 for the composite mode, and then reversed to be guided to the duplex tray 11. I will A gate 503 is provided at a branch point between the paper discharge outlet 502 from the transport path 501 to a sorter and the duplex tray 11 side, and a transport path is provided at a branch point leading to the synthesis mode inverter 10 on the duplex tray 11 side. Gates 505 and 506 for switching are provided, and a gate 507 is provided at the paper discharge outlet 502. The gate 507 is inverted by the triroll inverter 9 so that the copied surface can be discharged with the front side.

The upper tray and the middle tray are trays that can store a sheet size of about 500 sheets, A3 to B5, legal, letter, special B4, and 11 × 17. A tray motor 551 is provided as shown in FIG. 17, and the tray 552 is tilted when the number of sheets is reduced. As sensors, three paper size sensors 553-5 to detect paper size
55, a paperless sensor 556 for detecting running out of paper, and a surface control sensor 557 used for adjusting the height of the tray. There is also an emergency switch 558 for preventing the tray from rising too high. The lower tray is a tray that can store about 1100 sheets and can store the same paper size as the upper tray and the middle tray.

In FIG. 16, a duplex tray is a tray that can hold about 50 sheets and can hold the same sheet size as each of the trays described above. This is a tray for temporarily storing the copied paper when performing copying. Feed rollers 50 are provided on the entrance side conveyance path of the duplex tray 11.
9. A gate 505 is provided, and the gate 505 controls switching of sheet conveyance according to the combination mode and the duplex mode. For example, in the case of the double-sided mode, the sheet conveyed from above is guided to the feed roll 509 side by the gate 505, and in the case of the combining mode, the sheet conveyed from above is temporarily transferred by the gates 505 and 506 to the combining mode inverter. Then, when it is inverted, it is guided to the feed roll 510 and the duplex tray 11 side by the gate 506. In order to store paper in the duplex tray 11 and allow it to fall freely to a predetermined edge position, a tray inclination angle of about 17 ° to 20 ° is generally required. However, in the present invention, since the duplex tray 11 is accommodated in a narrow space in order to make the apparatus compact, a maximum inclination angle of 8 ° can be obtained. Therefore, the duplex tray 11 is provided with a side guide 561 and an end guide 562 as shown in FIG. In the control of the side guide and the end guide, when the sheet size is determined, the sheet is stopped at a position corresponding to the sheet size.

A high capacity tray (HCF) is a supply tray that can hold thousands of copy sheets. For example, it is often appropriate for a customer who does not need to make a copy by enlarging or reducing a document or a customer having a small copy amount to purchase the base machine alone. On the other hand, a customer who makes a large number of copies or a customer who requires a complicated copy operation often needs a duplex tray or a large capacity tray. As a means to fulfill these various requirements, this copier system has a structure that allows each additional device to be easily attached and detached, and provides an independent CPU (central processing unit) for some of the additional devices. Then, distributed control is performed by a plurality of CPUs. This not only has the advantage that the product desired by the customer is easily obtained, but also the possibility of installing new additional equipment teaches the customer the possibility of a new copying operation. This will greatly enhance the purchase of this copier system in promoting the evolution of office paperwork.

The manual feed tray (MSI) 16 is a tray capable of storing about 50 sheets and paper sizes A2F to A6F, and is particularly capable of using large-size paper that cannot be stored in another tray. Conventional manual feed trays of this type
Since the sheets are manually fed one by one, it is sufficient to preferentially send out the copy sheets from the manual feeding tray when the manual feeding is performed, and the operator does not need to select the manual feeding tray itself. On the other hand, the manual feed tray 16 of the present invention can set a plurality of copy sheets at the same time. Therefore, if the feeding from the manual feed tray 16 is performed with the set of copy sheets, the feed may be started when a plurality of copy sheets are set. In order to prevent such a situation, the manual tray 16 is selected.

In the present invention, compactness is achieved by adopting a configuration in which a nudger roll 513, a feed roll 512, and a takeaway roll 511 are integrally attached to a tray. After the leading edge of the paper is nipped by the takeaway roll 511, the feedout sensor detects the leading edge and pauses it to perform pre-registration to match the transfer position, and to absorb variations in the feeding of the paper at the feed section. doing. The fed sheet is fed to the transfer position of the photosensitive material belt 4 via the aligner 515.

(II-4) Automatic Document Feeder (DADF) In FIG. 19, the DADF 13 is mounted on the platen glass 2 of the base machine 1. In this DADF13,
A document tray 602 on which a document 601 is placed is provided. A delivery paddle 603 is arranged on the document sending side of the document tray 602, so that the documents 601 are sent out one by one. The fed document 601 is conveyed to an arc-shaped conveyance path 609 by a first driving roller 605 and its driven roller 606 and a second driving roller 607 and its driven roller 608. Further, the arc-shaped conveyance path 609 joins with the manual conveyance path 610 and is connected to the horizontal conveyance path 611. At the exit of the arc-shaped conveyance path 609, a third drive roller 612 and its driven roller 613 are provided. Is provided. The third drive roller 612 is vertically movable by a solenoid (not shown).

To be done. This reduces the sorting time. (C) and (d) show the stack mode, (c) shows an example in which four copies of four originals are copied for each original, and (d) shows the case where the maximum number of sheets per bin is exceeded. For example, when the number of sheets exceeds 50, they are stored in the next bin.

(III) Full stack control device (III-1) Features of full stack control device In a state where the last bin is used, that is, a full stack state in which a predetermined number of copy sheets are discharged to all bins, a full stack message is displayed. Whether you need to display is greatly related to the situation when a full stack occurs.
For example, when the copy is completed when there is a full stack and there is no original to be copied continuously, it is not necessary to display the message, and conversely, there is a problem that the display causes confusion for the user. On the other hand, when copying is in progress, it is not possible to continue copying the original document in the full stack state, so it is necessary to ask the user to remove the paper and release the bin. Display is mandatory. Therefore, it is necessary to judge the copy operation end state (copy completed or in the middle of copying) when the full stack occurs in order to display an appropriate message. The full stack control device of the recording apparatus of the present invention displays the full stack message in consideration of the situation when the full stack occurs, which will be described in detail below.

[A] Judgment of Copy Operation Completion State Whether the copy operation is completed or completed during copying can be determined by whether or not there is a document to be copied next. In the automatic document feeding (hereinafter referred to as ADF) mode that automatically places the document on the platen,
It can be easily determined whether or not the original to be conveyed next remains. However, in a mode other than ADF, for example, in the case of manually placing an original on the platen, a sensor is provided on the platen or the start of the next start button is detected to determine the end state of the copy operation. Etc. are adopted. In addition, regardless of ADF mode or modes other than ADF, in stack mode (II-5)
As described in the section of the sorter, in the copying machine of this embodiment, 1
When the maximum number of sheets per bin is exceeded, the next bin is automatically stored. Regardless, the operation ends during copying.

[B] Display Judgment As described above, in the present embodiment, two types of states, copy completion and copy in progress, are detected as the copy operation end state. However, in the copy completion in modes other than ADF, although the physical copy in the copying machine is completed, it is unclear whether the logical series of copies seen from the user side is completed.
Therefore, the display judgment of the full stack message is as follows in consideration of the copy mode information (ADF mode, modes other than ADF) and the copy operation end state.

When copy is completed in ADF mode The copy operation is completed normally and there is no original to copy next, so the display of the full stack message is unnecessary. Therefore, no message is displayed.

If copying is in progress in ADF mode The copy operation has not been completed. It is necessary to remove the copy paper from the sorter. So, for example, "Please remove the paper. Then, start again "is displayed.

When copying in a mode other than ADF Since this is a mode other than ADF, it is not possible to determine whether there is the next original, that is, whether a series of copying operations has been completed or is in the process of being completed. In this embodiment, for example, the full stack message is displayed when the start button is pressed next time. Thus, for example, when the copy is completed and there is no original to be copied, the message is not displayed because the start button is not pressed. Therefore, the user is not bothered by unnecessary messages. Also,
If you are in the middle of copying, press the start button continuously, so a message is displayed and you can know the full stack. The message may be displayed by detecting that the document on the platen has been replaced before the start button is pressed.

As described above, the full stack control device of the recording apparatus of the present invention reflects the situation at the time of occurrence of full stack in the copy operation end state, and determines the display based on the copy mode information and the copy operation end state, The stack is displayed.

(III-2) Full Stack Detecting Means FIG. 1 shows the structure of the full stack detecting means, which comprises an organic photosensitive material belt 4, a sequence manager 32, a sorter 19 and counters 19a and 19b provided on the sorter 19. Here, the organic photosensitive material belt 4 outputs a pitch signal which is a reference for starting the carriage based on the number of belt holes and the number of panels, and when the sequence manager 32 receives the input of the pitch signal, the sequence manager 32 sends the next signal to the sorter 19. Inquiry signal (NEXT PICTH
OK CMD) is output. When the sorter 19 inputs the inquiry signal, the counter 19a (the number of ejected copies of the currently used bin) is incremented by 1. The counter 19a can count up to the maximum number of sheets per bin (for example, 50 sheets), and is reset when that number is reached. Counter 19b
Is counting the number of bins currently in use, and counter 19
1 is added every time a overflows. For example, when the count value of the counter 19a is 30 (30 copy sheets are stored in the bin currently in use), 1 is added by the input of the inquiry signal, and the count value of the counter 19a becomes 31.
Becomes On the other hand, when the count value of the counter 19a reaches 50, it is reset and 1 is added to the counter 19b. Here, if the count value of the counter 19b exceeds the total number of bins, the sorter 19
Detects that the next pitch will be a full stack, and sends a full stack detection signal to the sequence manager 32.
When the sequence manager 32 receives the full stack detection signal, the copy paper of the pitch currently being copied is discharged and the operation of the machine is stopped in order to invalidate the next pitch. After that, when the operation of the machine is stopped and the sorter standby state (full stack) is input from the sorter 19, a full stack detection signal is output to the user interface 36 described later. In addition, when inputting the inquiry signal, the counter
Even if 19a is less than the maximum number of sheets that can be accommodated, the counter is
1 is added to 19b and the count value of the counter 19a is set to 1.

The output operation of the full stack detection signal described above will be described with reference to the time chart of FIG. 2 for simplicity
Assume a case where 41 sheets of originals are copied one copy at a time in a continuous sorter (a combination of two 20-bin sorters, so the total number of bins is 40).

When the first original is placed on the platen, the panel for copying first is conveyed to a predetermined position, and the pitch signal is input from the organic photosensitive belt 4 to the sequence manager 32, the sequence manager 32 moves the NEXT The PICTH OK command is output to the sorter 19 to inquire whether the next pitch is valid, in other words, whether there is a bin for ejecting the next copy. The counters 19a and 19b of the sorter 19 are each set to 1 as a count value, indicating that the current pitch is to be stored in the first bin as the first sheet. Counter 1 by entering NEXT PICTH OK command
9a adds 1 and becomes 2. However, since the number of copies is one in the stack mode, the next bin is used every time one copy is made. Therefore, 1 is added to the counter 19b, and the counter 19a is set to the count value 1 again. The counter 19b becomes 2 by adding 1 and indicates that the bin in which the next copy is to be discharged is the second bin.
Here, the count value indicated by the counter 19b is less than or equal to the total number of bins (40
Since ≧ 2), the sorter 19 responds to the sequence manager 32 with an OK signal indicating that the next pitch is valid.
Next, when the pitch signal is input to the sequence manager 32, the NEXT PICTH OK command is output, the counter 19b is added, and the count value indicated by the counter 19b is less than or equal to the total number of bins (40 ≧ 3). Is returned. Similarly, an OK signal is output from the sorter 19 for the pitch signals ~. Next, based on the pitch signal, NEXT PICTH O
When the K command is input from the sequence manager 32 to the sorter 19, 1 is added to the counter 19b and the count value becomes 4
It becomes 1 and exceeds the total number of bins of Sorter 19. Therefore, the next pitch cannot secure a copy paper discharge bin. In other words, since the sorter 19 becomes full stack at the current pitch, the full stack detection signal is answered and the next pitch is invalidated. When the sequence manager 32 receives the full stack detection signal, the sequence manager 32 stops the operation for the next copy, and further discharges the paper being copied to the final bin to stop the operation of the machine. At this time, the sorter 19 discharges the copy paper to the 40th bin, then transits to the sorter standby state, and outputs the sorter standby signal (full stack) to the sequence manager 32. Sequence manager
When the 32 receives the sorter standby signal following the full stack detection signal, it first recognizes the full stack state and outputs the full stack detection signal to the user interface (U / I).

(III-3) Judgment Means In this embodiment, the user interface 36 makes a full stack display judgment as one of the functions, and the display judgment based on the copy mode information and the copy operation end state described above is used as the timing shown in FIG. As shown in the chart, it is realized by checking the full stack display at each point while interfacing with the sequence manager 32 that constitutes the full stack detection means.

(1) POINT-1 A full stack is detected by the above-mentioned full stack detection means, and a full stack detection signal (FULL STACK CMD)
From Sequence Manager 32 to User Interface 36
Sent to The user interface 36 receives the full stack detection signal and generates FULL STACK information. Specifically, the FULL STA shown in the flowchart of FIG.
FULL STACK information flag is set to "1" by CK information reception processing
Set. If the FULL STACK information flag is "1", the message is displayed, and if it is "0", the message is not displayed.

(2) POINT-2 Sequence manager 32 to M / C STATE (STAND-BY)
If you enter, the first full stack check processing is performed based on the copy mode information and the copy operation end status, and "copy completed in ADF mode-> do not display message", "during copying-> display message", "AD
If the copy is completed in a mode other than F → a message is displayed when the start button is pressed next time ", the message is displayed if the copying is in progress. Specifically, the M / C ST shown in the flowchart of Fig. 27 (b) is used.
Perform steps 1 through 3 of FULL STACK CHECK processing when receiving an ATE.

Step: Judge the copy operation end status, and if copying is in progress, go to step Step ... Determine ADF mode or non-ADF mode from the copy mode information.

If the mode is ADF mode, go to step. If the mode is other than ADF, go to step.
This is equivalent to copying completed in F mode. Therefore, FULL STACK
Clear the information and change the setting value from "1" to "0".

Step: Transfer FULL STACK information to FULL STACK SAVE information. The FULL STACK SAVE information is a setting flag when a message is displayed when the start button is pressed next time, and the content of the FULL STACK SAVE information is "0" if the copy is completed in ADF mode, copy it in a mode other than ADF. If completed, "1" is set.

Step …… Clear the FULL STACK information and set the value to “0”.

Step …… CHEC displayed on FULL STACK MSG in Fig. 27 (c)
Do K. FULL STACK MSG display Check to see if FULL STACK information is set. If it is "1", display full stack message. Therefore, the message is displayed only when copying is in progress.

(3) POINT-3 When the start button is pressed, the user interface 36 performs the second full stack check process based on the FULL STACK SAVE information. Specifically, the FUL when the START KEY is pressed, as shown in the flowchart in Fig. 27 (d).
Perform steps 1 to 4 of L STACK CHECK processing.

Step …… Check the FULL STACK SAVE information,
Determine whether to display the message. FULL STACK SAVE Go to step if information is "1" (display message), go to step if "0" (do not display) Step, ...
Set the LL STACK information to "0".

Step: Since the process is reached through steps, the full stack processing is completed and the copy operation is possible. Therefore, M / C START CMD is transmitted from the user interface 36 to the sequence manager 32.

Step ... FULL STA to display the message
Set "1" to CK information.

Step …… Clear the FULL STACK SAVE information,
Set the value to "0".

Step …… CHEC displayed on FULL STACK MSG in Fig. 27 (c)
Do K. FULL STACK MSG display Check to see if FULL STACK information is set. If it is "1", display full stack message. Therefore, if the FULL STACK SAVE information is "1" in the step judgment, that is, the copy is completed in a mode other than ADF, a message will be displayed.

As described above, by checking the full stack display at each point while interfacing with the sequence manager 32, F-point at POINT-1
Generates ULL STACK information and displays a full stack message when copying is in progress at POINT-2, then the start button is pressed, and displays a message when copying is completed in a mode other than ADF at POINT-3 be able to.

(III-4) Display means A CRT display of a user interface is used as a display means of the full stack control device.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the full stack detection means, the sequence manager 32 and the sorter 19 communicate with each other based on the pitch signal to detect the full stack. May be managed to detect the full stack. Also, the POINT of the judgment means
The display determination may be made at -1, and only the display may be made at POINT-2, 3. The display means is not particularly limited as long as it has a message display function such as a panel.

〔The invention's effect〕

As described above, according to the full stack control device of the recording apparatus of the present invention, when the full stack is detected in the stack mode, the display determination is performed based on whether or not the copy operation is continued, and based on the determination result. Since the full stack message is displayed or not displayed by the display means, unnecessary messages that confuse the user can be prevented from being displayed, and the full stack message can be displayed at an appropriate timing according to the situation. I was able to display the message. In addition, this makes it possible to improve the operability of the storage device.
