Abstract

PURPOSE:To carry out no indication of unnecessary message by providing a judging means for judging whether or not to carry out a full-stack indication at the time of receiving first and second detecting signals in a stack mode and a control means for making an indicating means indicate a full-stack message based on the judgement. CONSTITUTION:At the time of detecting the full-stack condition in which sheets of copying paper are discharged into all bins and a copy continuing condition for continuing a copying operation by detecting means (4, 32, 19), a copy mode is checked by a judging means 36 to carry out the judgment of indicating, e.g., 'Indicate no message.', 'Indicate a message.', etc. Then, based on this indication judgment, a control means makes an indicating means carry out the indication. Thereby, the indication of unnecessary message is not carried out while carrying out the indication of a full-stack message at a proper timing in line with the condition.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a full-stack control device for a recording device, and in particular, the present invention relates to a full-stack control device for a recording device, and in particular, a full-stack control device that does not display unnecessary messages and performs full-stack control at an appropriate timing according to the situation. -Relates to a full stack control device for a recording device that is capable of displaying messages.

[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, and the functions that can be used have become more diverse. Same size copy, reduction, enlargement.

Copy Density Selection 9 In addition to main functions such as duplex copying, for example, even if the original is placed on the platen, there is a method where the user manually places the original on the platen, and semi-automatic original feeding (S
ADF) or automatic document feeder (ADF)
There are methods such as Regarding the ejection of copy paper, there are a non-sort mode, a sort mode 1, a stack mode, etc. In response to such diversification of functions, there are many types of condition settings such as function selection and function settings, and various operations are required. In addition, problems such as paper jams and out-of-copy paper can occur in a variety of ways, including the nature of the occurrence and the location of the occurrence, so detailed responses are required for status display and operation guidance.

One of the status display/operation guidance messages regarding the copy paper output section is a full stack message that is displayed when all the sorter pins are used. As mentioned above, copy paper output modes include non-sort mode, sort mode, stack mode, etc. Among these, non-sort mode uses only the output tray,
The sort mode presets the number of copies within the prepared number of pins (the total number of pins of the installed sorter, for example, 20 pins or 40 pins), so the total number of pins will not be exceeded, and therefore a full stack・No need for messages. However, in stack mode, in which copies of one document are stored in one pin, the number of copy sheets is loaded sequentially starting from the first pin, so for example, the total number of pins on the sorter is 2.
In the case of 0 pin, the second
There is a problem in that if the 0th pin, that is, all the pins are used, and then the 21st original is to be copied, no pins for ejection can be secured. For this reason, conventional full-stack control devices detect a full stack when a predetermined number of copy sheets are ejected to the last pin, and remove, for example, r paper at the same time as stopping machine operation. Then, a full stack message such as "Please start again" is displayed on the console panel, etc. This allows the user to recognize that all the pins have been used, and based on the displayed content, the user can take out the copy paper from the sorter and make another copy.

[Problem to be solved by the invention]

However, according to conventional full-stack control devices, a full-stack message is displayed unconditionally when the last pin is used. For example, when copying 20 originals, the 20th pin The copying operation is completed normally when the predetermined number of □copy sheets are ejected, but at the same time, by using the 20th pin, a full stack is detected and a full stack message is displayed. Therefore, there are problems such as displaying inappropriate and unnecessary messages, which may confuse the user and cause copy mistakes.Furthermore, when the final pin is used, the copy operation is still in progress, or the copy process is not complete. Judging whether the operation has ended depends on the number of originals, how the originals are placed, etc., so it is difficult to display the necessary message at the right time without confusing the user. There is a problem.

An object of the present invention is to provide a full-stack control device for a recording device that does not display unnecessary messages that confuse users and improves operability.

Another object of the present invention is to provide a full-stack control device for a recording device that can display a full-less tank message at an appropriate timing depending on the situation.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention, when the detection means detects that copy paper has been ejected to all the pins, displays the display based on the copy mode information and the copy operation completion state by the determination means. A full stack message is displayed by the display means based on the determination result. Alternatively, it provides a full stack control device for a recording device that does not display any information.

That is, the full stack control device for the recording apparatus of the present invention includes the following means.

(1) Detection means When a predetermined number of copy sheets are ejected to all pins (full stack state), outputs a full stack detection signal and continues copying based on whether the copying operation continues. Outputs a detection signal.

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

(3) Control means controls the display means based on the display determination to display a full stack message.

[Effect]

In the full stack control device of the recording apparatus of the present invention, when the detection means detects the full stack state in which copy sheets are ejected to all pins and the copy continuation state in which the copying operation continues, the determination means checks the copy mode. For example, a display determination is made such as Jl not displaying an r message, J displaying an f message, etc., and based on the display determination, the control means causes the display means to display. As a result, unnecessary messages are not displayed, and a full stack message is displayed at an appropriate timing according to the situation.

(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 change the display screen on the CRT display to categorize it into basic copy, advanced copy, and specialized copy modes, 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 A2.86 to B3, but also for non-standard paper sizes, and as explained earlier, it has a built-in tray of three stages. Furthermore, it is possible to adjust the fixed magnification in 7 stages, to adjust the magnification in 1% increments, and to finely adjust the magnification 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 function to set left and right binding margins individually in the range of 1 mm to 16 mm, a pilling function, etc.

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

Additional functions include composite copy, interrupt, preheating mode, clearing the set number of sheets, clearing all to auto mode, information explaining the function, P key for using an IC card, maximum lock document return to limit the number of set sheets, etc. Fully goblin recovery using DADF, purge to eject paper other than the jammed area, full copy without blurring, editor to copy or delete parts of the original, job program to call and process jobs one by one, blank paper. There are mounts that insert one sheet at a time between copies, and center eraser/frame eraser used for books.

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

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

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

(B) Features The entire system described in this description, which includes 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) Improved reliability We aim to reduce component failure and extend life, clarify the in/out conditions for each parameter, and reduce design defects.
We are trying to realize a 100kCV without maintenance.

(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 color-mixing 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 placed around it in correspondence with the screen, making mode setting possible with easy-to-read display menus 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 certain operations.

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

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

This copying machine has a base machine l shown in FIG. Assume that the copying machine has an advanced system configuration.Some of the co-users are
Some people or departments may require a DADF 13 or a 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 cases, IC cards should be prepared according to the usage pattern of each person or department, and the person or department who wants advanced functions will have to pay more for the basic costs.
It is sufficient to make it possible to utilize many functions. For example, the owner of the most advanced IC card
By operating the copying machine with the card set in the IC card device, the DADF 13, sorter 19, supply trays (6-1 to 6-3), and duplex tray 11 can be used freely. Efficiency can also be improved. On the other hand, people who do not need to sort copy paper can save money by using only the catch tray 20 and using an IC card that lacks a sorting program.

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

A plurality of copying machines are arranged in the store, and an IC cart device 22 is attached to each copying machine. The customer requests an IC card according to the type of service, sets it in the copier of his/her choice, and makes a self-service copy. Customers who are unfamiliar with copying machines can request an IC card that is programmed to display operating instructions, and by inserting this card, various operating information can be displayed on Ul 12, ensuring that copying operations can be carried out without error. can. D.A.
Whether or not the DF 13 can be used and whether multicolor recording can be performed can be determined by the IC card provided, and it is also possible to restrict the types of models used, making it possible to manage customers according to the price.

Furthermore, since the actual status of copying operations, such as the number of copies and the size of the copying paper used, can be recorded on the IC card, billing for fees becomes easier, and detailed services such as discounts on copying fees for regular customers are also possible. .

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

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

For example, in the case of a patent office, by purchasing a dedicated IC card, in addition to the usual several types of reduction ratios, two
You can easily select a reduction ratio of 00%. Furthermore, within a range that requires fine adjustment, the reduction ratio can be set in steps of 1%, for example. Furthermore, the department issuing resident records can now use keys such as a numeric keypad to instruct the type of resident record and fields and items to be deleted on a display such as a liquid crystal display, and then press the start button. By pressing this button, only the desired range of the original will be copied, or only the necessary parts will be edited and recorded.

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

A copying machine system to which the present invention is applied includes an SQMGR subsystem 32 on a main board 31, as shown in FIG.
, CHM subsystem 33.1 MM subsystem 34,
Four subsystems consisting of the marking subsystem 35, the surrounding U/I subsystem 36, and the INPUT
Subsystem 37.0UTPUT Subsystem 38, O
It is composed of nine subsystems including five subsystems including a PT subsystem 39 and an IEL subsystem 40. In contrast to the SQMGR subsystem 32, the CHM subsystem 33 and 1MM subsystem 34° are executed by software under the main CPU 41 shown in FIG. 4 together with the SQMGR subsystem 32. Connected by inter-system interface ° (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, duplex tray, manual feed tray, copy paper feed control, and copy paper purge operation.

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

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

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

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

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

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

The IEL subsystem 40 is a subsystem that erases unnecessary images on the photosensitive material 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 as shown in FIG. 4 as the core, and can flexibly respond to combinations of the base machine 1 and its surroundings (additional devices, etc.).

Here, the main CPU 41 is located on the main board of the base machine 1, includes software for the SQMGR subsystem 32, CHM subsystem 33, and IMM subsystem 34, and is connected to each CPU 42 to 47 via a serial bus 53. .

These CPUs 42 to 47 have a one-to-one correspondence with each subsystem connected through 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 predetermined timing, with one communication cycle being 100 m5ec. Therefore, for signals that mechanically require strict timing and cannot match the timing of serial communication, each CPU is sent to an interrupt board (IN).
T terminal signal) is provided, and interrupt processing is performed by a hot line separate from the serial bus 53.

That is, for example 64 c pm (A4 LEF),
If a copy operation is performed at a process speed of 309 mm/sec and the control accuracy of the registration gate is set to ±1 mm, a job will occur that cannot be processed in the communication cycle of 100 m5ec as described above. 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 this configuration is (i) If the operation control programs for all these additional devices were to be prepared in the base machine 1, the memory capacity required for this would be enormous. Depends on what happens. Also,(
ii) If a new additional device is developed in the future or the current additional device is improved, the ROM in the base machine 1
This is to make it possible to utilize these additional devices without replacing or expanding the read-only memory.

For this reason, the base machine 1 includes a basic storage area for controlling the basic parts of the copying machine and an additional storage area for storing the program loaded with the functional information of the present invention, which is composed of an IC card. Additional storage area includes DADF
Various programs such as a control program for the computer 13 and a control program for the user interface 12 are stored. Then, when an IC card is set in the IC card device 22 with a predetermined additional device attached to the base machine l, 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 area, or has a priority position over this program. The memory used here is a random memory backed up by batteries.
It is a non-volatile memory consisting of access memory.

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 operational burden on the operator, this copier allows settings such as image density and magnification to be preset, and these preset values are stored in non-volatile memory. ing.

(1-4) Serial Communication Method FIG. 5 is a diagram showing the transfer data structure and transmission timing of serial communication, and FIG. 6 is a time chart showing mutual communication intervals in one communication cycle.

In the serial communication performed between the main CPU 41 and each CPU (42 to 47), data amounts as shown in FIG. 5(a) are allocated to each. In the 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 transmission timing to the next slave, that is, the optical CPU 45 is 1+ ( c) is 26 m5. According to this example, the total communication amount is 86 bytes, and at a communication speed of 96008 PS, the period is about 100 m5.The data length is shown in (b) of the same figure. It consists of a header, a command, and data as shown in FIG. 6. When transmitting and receiving data with the maximum data length as shown in FIG. 6(a), the entire communication cycle is as shown in FIG.

Here, from the communication speed of 9600 BPS, the time required to send 1 byte is 1.2 mS, the time from when the slave finishes receiving to when it starts sending is 1 mS, and as a result, 100 m5 is one communication cycle. .

(1-5) State division FIG. 7 is a diagram showing the state portion 11J of the main system.

State division divides the state from power ON to copy operation and after the copy operation is completed into several parts, determines the jobs to be performed in each state, and moves to the next state if all jobs in each state are not completed. This is to ensure efficiency and accuracy of control by ensuring that the main system is not in any state. Find out what you are doing 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 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 Colts lamp is turned on and the fuser idle rotation is performed for a predetermined period of time.
When the fuser reaches the predetermined control temperature, U/I
displays "You can copy" in the message. This standby state takes about several tens of seconds when the power is turned on for the first time.

Setup is a preparatory state for copying when the start button is pressed to start, the main motor and sorter motor are driven, and the photosensitive material belt ■. Adjust constants such as 7 etc. Also, the ADF motor turns ON, the feeding of the first document starts, the first document reaches the registration gate, the document size is detected, the tray and magnification are determined in the APMS mode, and the ADF document is placed on the platen. be included. Then, the second document from the ADF is sent to the registration gate, and a transition is made to cycle up.

Cycle up is a state in which the belt is divided into several pitches and panel management is performed until the first panel reaches the get park point. That is, the pitch 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 set 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 bark 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 (8 autom
atic Density Control),
AE (Auto-matic Exposure)
, DDP control, etc., and repeat the copying operation. Then, when R/L = the number of sheets counted, the originals are exchanged, and when this is done for a predetermined number of originals, a coincidence signal is output and a 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, and each corotron, developing machine, etc. is set to 0FFL, and the next panel after the last used panel is stopped at the stop bark position. panel management to ensure that only specific panels are not used and fatigue occurs.

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, even from a set amp or cycle up, there is a transition to cycle down due to jam occurrence, etc.

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

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

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

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

(II-1) Optical system FIG. 8(a) is a schematic side view of the optical system, FIG. 8(b) is a plan view, and FIG. 8(C) is a side view in the XX direction of FIG. 8(b).

The scanning exposure device 3 of this embodiment employs a PTS (Preset Imaging System) method in which an image is exposed onto the photosensitive material at a speed faster than the moving speed of the photosensitive material belt 4, and a second scanning system B is used. A system is adopted in which the scanning system A is fixed and the first scanning system A is movable independently. That is, the first
Scanning system A includes an exposure lamp 102 and a first mirror 103.
The scanner scans an original placed on a platen glass 2. The scanner 101 scans an original placed on a platen glass 2. On the other hand, the second scanning system B includes a third carriage 109 having a fourth mirror 110 and a fifth mirror 111;
It consists of a fourth carriage 112 having a sixth mirror 113. In addition, the third mirror 107 and the fourth mirror 1

The carriage 109 is made to move in the same direction at a speed of 2/2.

Further, as shown in FIG. 8(b), the transmission shaft 117 is provided with a PIS clutch 125 (electromagnetic clutch) for transmitting the rotation of the timing pulley 117a to the timing pulley 117b.
5 is turned off, it is engaged and the rotating shaft 115
rotation is transmitted to the transmission shafts 117, 123. Also, P
When the IS clutch 125 is energized and released, the rotation of the rotary shaft 115 is not transmitted to the transmission shafts 117 and 123. Further, as shown in FIG. 8(c), an engaging protrusion 1 is provided on the side surface of the timing pulley 116a.
26a is provided, and when the LDC rotor solenoid 127 is turned on, the engagement piece 126b engages with the engagement protrusion 126a, fixing the transmission shaft 116, that is, fixing the first scanning system A, and turning on the LDC lock switch 129. That's what I do.

In the scanning exposure apparatus configured as described above, the exposure method of PIS (Preset Imaging System) mode and N0N-PIS mode is selected by disengaging and disengaging the PIS clutch 125. In the PIS mode, for example, when the speed is 65% or more, the PIS clutch 125 is engaged and the second scanning system B is moved at a speed of 2, thereby moving the exposure point of the photosensitive material belt 4 in the opposite direction to the photosensitive material, and The scanning speed v1 of the system is made relatively faster by the process speed (2) to increase the number of copies per unit time.

At this time, if the magnification is M, then V, = V, X3.5/(3
, 5M-1), and M=LVP=308.9mm/
s, then ■1=432.5 mm/s. Also,■
2 is determined by the diameters of the timing pulleys 117b and 123a and is v, = (1/3 to 1/4)V. On the other hand, in the N0N-PIS mode, in order to suppress the power consumption by preventing an increase in the speed of the scanning system and an increase in illumination power during reduction, for example, if the power consumption is 64% or less, the PIS clutch 125 is released and By turning on the PIS lock solenoid, the second scanning system B is fixed and the exposure point is fixed and scanned, thereby avoiding an increase in the load on the drive system and the document illumination power, and contributing to the realization of 1.5KVA. It is.

The lens 108 is mounted on a lens carriage 13 disposed below the platen glass 2, as shown in FIG. 9(a).
It is slidably attached to a support shaft 136 fixed to 5. The lens 108 is connected to a lens motor Z137 by a wire (not shown), and the lens motor Z
The rotation of 137 moves the lens 108 along the support shaft 136 in the Z direction (vertical direction in the figure) to change the magnification. Further, the lens carriage 135 is slidably attached to a support shaft 139 on the base side, and is connected to a lens motor X140 by a wire (not shown). Along 139, X direction (horizontal direction in the figure)

37.140 is a four-phase stepping motor. When the lens carriage 135 moves, the pinion 142 provided on the lens carriage 135 moves the lens cam 143.
This causes the large gear 144 to rotate and move the mounting base 146 of the second scanning system via the wire cable 145.

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

Further, as shown in FIG. 9(b), a lens shutter 147 is provided on one side of the lens 108 so that it can be opened and closed by a link mechanism 148. By turning on and off a shutter solenoid 149, the lens shutter 147 is closed during image scanning.
opens, and closes when the image scan is completed.

The purpose of blocking light with the lens shutter 147 is to form a DDP patch and an ADC patch on the belt photosensitive material.
The purpose is to prevent image erasure when the second scanning system B returns in the PIS mode.

FIG. 10 shows a block configuration diagram showing an overview of the subsystem of the optical system. The optical CPU 45 is connected to the main CPU 41 through serial communication and a hotline, and controls each carriage, lens, etc. in order to form a latent image on the photosensitive material according to the copy mode transmitted from the main CPU 41. Control power supply 1
52 is for logic (5V) and analog (±15V)
, solenoid, and clutch (24V), and the motor power supply 153 is 38V.

The carriage registration sensor 155 is arranged to correspond to the registration position of the first mirror 101, and an actuator attached to the first scanning system A is arranged to correspond to the registration position of the first mirror 101.
55, a signal is output. This signal is sent to the optical CPU 45 to determine the position or timing for performing registration, and determines the home position P when the first scanning system A returns. Additionally, a first home sensor 156a and a second home sensor 156b are used to detect the position of the carriage.
The first home sensor 156a is arranged at a predetermined position between the registration position and the stop position of the first scanning system A, and detects the position of the first scanning system A and outputs a signal. . Further, the second home sensor 156b detects the position of the second scanning system and outputs a signal.

The rotary encoder 157 is connected to the carriage motor 114
It is of the type that outputs A-phase and B-phase pulse signals with a phase shift of 90'' depending on the rotation angle of the
At 0 pulse/rotation, the shaft pitch of the timing pulley of the first scanning system is designed to be 0.1571 mm/pulse. The biasing solenoid 159 moves a biasing lens (not shown) in the vertical direction under the control of the CPU 45, and the movement of the biasing lens is confirmed by the on/off operation of the biasing switch 161. Lens home sensors 161 and 162 are sensors that detect the home positions of lens X motor 140 and lens X motor 137. LDC rotsuta solenoid 1
Reference numeral 27 fixes the first scanning system A at a predetermined position under the control of the CPU 45, and the LDC lock switch 129 confirms that the first scanning system A is locked.

The PIS lock solenoid 131 locks the second lock solenoid when the PIS clutch 125 is released in the N0N-PIS mode.
This fixes the scanning system B, and confirms that it is locked using the PI3 port/link switch 132. The PIS clutch 125 is of a type that releases the clutch when energized and engages the clutch when not energized, and contributes to reducing power consumption in PIS mode and achieving 1.5 KVA.

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 (2), and acceleration control during scanning is performed (step (2)).

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 ■), cancel PLL mode, set to speed mode, and move the carriage motor in the return direction (
CCW). Then, in step ■, C
It is determined whether or not there is an interrupt from W to CCW (reverse rotation signal), and if so, acceleration control is performed at the time of return (step ■), and when the encoder count reaches the preset braking start point ( Step [phase]), performs deceleration control during return (step ■), and stops the carriage motor if there is a reverse rotation signal again.

(Step @). Also, as shown in (b), the number of counts to turn on (open) the shutter is set, and when the encoder clock number exceeds the shutter-on count, the shutter opens, and when the encoder clock number exceeds the shutter-off count, the shutter is opened. Close the shutter and end the image scan.

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

The imaging system is managed by the 1MM subsystem 34, which writes and erases latent images. The marking system is managed by the marking subsystem 35, and is
Performs exposure, surface potential detection, development, transfer, etc. In the present invention, as described below, the MM 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, batch formation, etc. It's moving.

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

An organic sensitive material belt 4 is arranged inside the base machine 1. Since the organic photosensitive material belt is coated with multiple layers such as a charge generation layer and a transfer layer to form the photosensitive material, it has a greater degree of freedom than a photoreceptor drum, which forms the photosensitive material by vapor depositing Se.
Since it is easier to manufacture, costs can be reduced, and the space around the belt can be increased, making layout 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 belt seam to detect this, and pulses are generated according to the rotational speed of the main motor. is generated by an encoder to form a machine clock, and by constantly counting the -period machine clock, a pitch signal that becomes a reference for starting the carriage according to the expansion and contraction of the belt,
Correct the registration timing.

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

The organic sensitive material belt 4 is a charge corotron (charger) 21
1, and is uniformly charged and driven clockwise in the figure at a constant speed. Then, when the first panel arrives a certain time before the register (exposure location) 231, a pitch signal is output, and the timing of carriage scan and paper feed is determined based on this signal. The belt surface charged by the charge corotron 211 is exposed at an exposed location 231
exposed to light. A light image of a document placed on a platen glass 2 placed on the top surface of the base machine l is incident on the exposure location 231 .

For this purpose, an exposure lamp 102 and a plurality of mirrors 101 to 1 that transmit reflected light from the document surface illuminated by the exposure lamp 102 are provided.
13 and an optical lens 108, among which mirror 101 is scanned to read the original. Further, mirrors 110, 111, and 113 constitute a second scanning optical system, which is a PIS (Precession
There is a limit to increasing the process speed, so it is called Image 5can). In order to increase the copying speed without any trouble, the second scanning optical system scans in the opposite direction to the belt movement direction to increase the relative speed, up to 64 sheets/min (CPM).
I am trying to achieve this.

An electrostatic latent image corresponding to the original is formed on the organic sensitive material belt 4 by the image information exposed in a slit shape at the exposure location 231 . And IEL (Interimage Lamp)
After erasing unnecessary images, images between images, and side erasing in step 215, a developing device 216 for electrostatic latent images, usually black-toned toner.
, or is developed by a color toner developing device 217 to create a toner image. The toner image moves with the rotation of the organic sensitive material belt 4, and is transferred to the pretransfer corotron 1.
:Photograph) 218,) Passes near the transphacorotron 220. The pretransfer corotron 218 is
Usually, this is done to weaken the electrical adhesion of the toner by applying an alternating current to facilitate the movement of the toner. Also, since the belt is made of a transparent material, before transfer, a pre-transfer lamp 225 (also used for erasing) irradiates the belt with light from the back to further weaken the electrical adhesion of the toner, and transfer is performed. make it easier

On the other hand, the copy paper stored in the supply tray of the Heas machine 1 or the copy 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 belt 4. It passes between corotrons 220. Paper feed is basically L E F (Long EdgeFeed
), 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 picking point, and the toner image is transferred onto the copy paper. Then, the paper and the photosensitive belt 4 are peeled off by a corotron 221 and a strip finger 222, and the copy paper after transfer passes between a heat roll 232 and a pressure roll 233 to be thermally fixed, and then transferred to a conveyor roll 234, 235. and is discharged onto a discharge tray (not shown).

The sensitive material belt 4 from which the copy paper has been removed is easily cleaned by a pre-clean corotron 224, unnecessary charges are erased by light irradiation from the back side by a lamp 225, and unnecessary toner, dust, etc. are scraped by a blade 226. be dropped.

Note that patches are formed between images on the belt 4 by a patch generator 212, and the electrostatic potential of the patch portion is detected by an ESV sensor 214 for density adjustment. Further, as described above, the belt 4 has holes, and the belt hole sensor 213 detects the holes to detect the belt speed and perform the process speed control 1. In addition, an ADC (Density Control) sensor 219 detects the degree of toner adhesion by comparing the amount of light reflected from the toner on the patch with the amount of reflected light when there is no toner, and a pop sensor 223 makes sure that the paper does not peel off. The case where the belt is wrapped around the belt 4 is detected.

FIG. 13 shows how the photosensitive material belt 4 is divided into panels.

Since the belt 4 has a seam part 251, the image is not placed there, and a belt hole 252 is provided at a certain distance l from the seam part, for example, with a circumference of 1158 m.
In the case of m, 2 is 70 mm. 253.25 in the figure
4 is the first and last panel when the photosensitive material belt surface is divided into N-ply retches, B in the figure is the interval between panels, C is the panel length,
D is the pitch length of the panel, and in the case of 4 pitch division, it is 289. 5mm, 386m if divided into 3 pitches
m, and in the case of 2-pitch division, it is 579 mm. Seam 2
51 is the L E (Lead Edge) of the panel 253.
) and the T E (Tail Edge) of the panel 254, so that A=B/2.

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

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

To outline the functions of the IMM subsystem 34, it performs serial communication using rEL difference 4-difference color 0 line, sends interrupt signals through a hotline for highly accurate control, manages image formation, and also controls the marking subsystem. 35, sends a control signal to the CHM subsystem 33 to control the belt.

It also detects holes in the organic photosensitive material belt 4 to control the main motor, and also determines the panel forming position and performs panel management. In addition, in 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. When the start key is pressed, the setup state is entered, and ■ prior to copying. Constants such as OF are adjusted, and when the copy cycle begins, edges are erased at the leading and trailing edges of the image based on the document size to form a necessary image area. A patch is also formed in the inter-image area to form a patch for toner density adjustment. Furthermore, the jam factor,
When a hard down factor such as belt failure is detected,
Stops the belt or communicates with the sequence manager to stop the machine.

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

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

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

The document size is input manually from the platen document size sensor 36~S1°, and from this and the paper size, IEL215
The scrubbing area is determined by

A belt hole signal is input from the belt hole sensor 213, and 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.

Further, the belt is driven by the motor via a belt clutch 267, and only the belt can be selectively stopped. A pulse is generated from an encoder in synchronization with the rotation of this motor, and this is used as a machine clock to obtain a machine clock that corresponds to the belt speed.

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

In addition, the 1MM subsystem is the IEL subsystem 40
In addition to performing serial communication with the
It sends out L image signals, ADC patch signals, and IEL black band signals. The IEL subsystem 40 uses the ADC patch signal to specify the shape and area of the patch area formed by the patch generator 212, and adjusts the amount of charge to adjust the electrostatic potential. is adjusted to a constant potential of 500 to 600V. In order to prevent the belt 4 from being damaged 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. This prevents the belt 4 from being damaged even when copying is performed when the amount of toner is extremely small as in the current situation.

Furthermore, the IMM communicates with the marking subsystem 35 via a hotline, and uses the optical registration signal as a reference to generate patch formation request signals, bias request signals,
Sends an ADC request signal. Marking subsystem 3
5 receives this and drives the drumstick generator 212 to form a patch, drives the ESV sensor 214 to detect the electrostatic potential, and drives the developing machines 216 and 217 to form a toner image. . It also controls the drive of the pre-transfer corotron 218, transfer corotron 220, and pig corotron 221.

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

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

The IMM sends a registration gate trigger signal to the CHM subsystem 33 to control the paper so that the leading edge of the image coincides with the paper at the tacking point, and if it is necessary to correct the opening timing of the registration gate, it controls the amount of correction. Calculated and sent.

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

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

FIG. 15 shows a timing chart.

The reference time for control is the optical register and sensor position. The IEL is turned off after a predetermined time (T1) of the optical registration sensor on/off signal. That is, it is turned on until T1 to erase the leading edge, and after T2, it is turned on to erase the trailing edge. In this way, image formation is performed using the IEL image signal, and by controlling the registration gate timing, the leading edge of the sheet at the picking point and the leading edge of the image are aligned. After image formation is completed, AD is activated by the patch generator request signal (T5 after the reference time).
A C patch signal is generated to form a patch in the inter-image. After patch formation, a bias request signal is issued (after T6) to perform development, and then an ADC request signal is issued (after T7) to detect toner density. Further, a black band is formed in the inter-image by the black band signal.

Note that during AE (Auto Exposure) scanning, 0N10FF of the IEL image signal is not performed.

(It-3) Paper conveyance system In FIG. 16, the upper tray 6-1 serves as a paper tray.
．． A middle tray 6-2, a lower tray 6-3, and a duplex tray 11 are installed in the base machine, and a large capacity tray (HCF) 17 is installed on the side as an option.
A manual feed tray (MSI) 16 is equipped, 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, it is possible to
When one supply tray runs out of copy paper, automatically feeds copy paper of the same size from another supply tray.

The copy paper is fed by a specially provided feed motor, and a step motor is used as the feed motor. A feed sensor detects whether copy paper is being fed normally. A gate solenoid is used for registration to align the leading edge of the copy paper once it has been sent out. This gate solenoid is different from other types of solenoids in that it is controlled so that when energized, the gate opens to allow copy paper to pass through. Therefore, in the standby state when copy paper does not arrive, power is not supplied to the gate solenoid (the gate remains open to reduce power consumption. The solenoid is energized and the gate is closed to prevent the copy paper from passing.Then, at a predetermined timing, when the conveyance of the copy paper is resumed, the energization is stopped and the gate is opened.When such control is performed, The variation in the position of the gate at the time when the leading edge of the copy paper is prevented from passing is reduced, and even if the copy paper is pressed against the gate with a relatively strong force, it can be accurately positioned.

When copying is performed again using a duplex mode in which copies are made on both sides of a sheet of paper or a composite mode in which copies are made multiple times on the same side, the sheets are guided to a conveyance path where they are stacked on a duplex tray 11. In the duplex mode, the sheets are stacked directly from the conveyance path to the duplex tray 11, but in the composite mode, they are first stacked from the conveyance path to the composite mode inverter 10.
Thereafter, it 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 11 side, and a gate 503 is provided at the branch point leading to the composite mode inverter IO 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, and by inverting the paper using the tri-roll inverter 9, the paper can be ejected with the copied side facing up.

The upper tray and middle tray can hold approximately 500 sheets of paper1
This tray can accommodate paper sizes of , A3-B5, Legal, Letter, and Special B4.11X17. And the 17th
As shown in the figure, it has a tray motor 551, and has a structure in which the tray 552 tilts when there is less paper.As sensors, there are three paper size sensors 553 to 555 that detect paper size, and one that detects paper out. It is equipped with a no paper sensor 556 and a surf ace control sensor 557 used to adjust the tray height.There is also an emergency switch 558 to prevent the tray from rising too high.The lower tray has a paper capacity of 110 sheets.
This tray can accommodate approximately 0 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 509 and a gate 505 are arranged on the entrance side conveyance path of the duplex tray 11, and the gate 505 controls switching of sheet conveyance according to the combination mode and duplex mode. 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 composite mode, the paper conveyed from above is guided to the gate 505,
506 leads to the inverter 10 for the -H synthesis mode, and then, when reversed, is led to the feed roll 51O and 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, it is generally 17° to 20°.
A tray inclination angle of about 6 is required. However, in the present invention, since the apparatus is made more compact and the duplex tray 11 is housed in a narrow space, the tilt angle is only 8 degrees at maximum. Therefore, as shown in FIG. 18, the duplex tray 11 includes side guides 561,
and an end guide 562 are provided. In controlling these side guides and end guides, once the paper size is determined, the paper is stopped at a position corresponding to the paper size.

A high capacity tray (HCF) is a supply tray that can accommodate dozens of sheets of copy paper. For example, for customers who do not need to enlarge or reduce originals to make copies, or for customers who only make a small amount of copies, it is often appropriate to purchase a base machine alone. On the other hand, customers who make a large number of copies or who require complex copying operations often require a duplex tray or a high-capacity tray.

As a means to meet these various demands, this copier system has a structure that allows each additional device to be easily attached or removed, and some of the additional devices are equipped with independent CPUs (central processing units). The system is designed 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 (MST) 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 conventional manual feed trays of this type manually feed one sheet at a time, the operator only needs to feed copy sheets 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 sheets are set and fed from the manual feed tray 16, there is a possibility that the feeding will start when a plurality of copy sheets are set.

In order to prevent such a situation, the manual feed tray 16 is selected.

In the present invention, compactness is achieved by adopting a configuration in which the nuja roll 513, feed roll 512, and takeaway roll 511 are integrally attached to the tray.

After the leading edge of the paper is nipped by the take-away roll 511, a feedout sensor detects the leading edge and pauses it, thereby performing pre-registration to align the transfer position and absorbing variations in paper feeding at the feeder unit. are doing. The fed paper is fed to the transfer position of the photosensitive material belt 4 via the aligner device 515.

(If-4) Automatic document feeder (DADF) In FIG. 19, the DADF 13 is mounted on the platen glass 2 of the base machine 1. This DADF 13
is equipped with a document tray 602 on which a document 601 is placed. A delivery paddle 603 is disposed on the original delivery side of the original tray 602, which allows the original 60 to be sent out.
1 is sent out one by one. The sent document 601 is conveyed to an arcuate conveyance path 609 by a first drive roller 605 and its driven roller 606, and a second drive roller 607 and its driven roller 60B.

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

A fourth drive roller 617 is provided in the reversing conveyance path 616. Further, a belt drive roller 619 is provided on the platen glass 2 facing the exit of the horizontal conveyance path 611, and a belt 6 stretched between the driven rollers 620.
21 can be rotated forward or reverse. A fifth drive roller 622 is provided at the exit of the belt conveyance section, and a sixth drive roller 623 is provided in the manual feed conveyance path 610. Two driving rollers 623 are provided in the front and rear directions of the base machine 1 (in the direction perpendicular to the plane of the paper in the figure), and are configured to be able to simultaneously feed two originals of the same size. Note that 625 is a cleaning tape that cleans the surface of the delivery paddle 603 by the seventh drive roller 626.

Next, referring to FIG. 20, photosensors S, -S, □
I will explain about it. SI is the original 6 on the original tray 602.
S2 is a take-away sensor that detects the passage of a document, Sol, S4
are feed sensors provided before and after the manual feed conveyance path 610; . is a paper size sensor that detects the size of the original; Sl+ is an ejection sensor that detects whether the original has been ejected; and StZ 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 the platen mode, and there are 6 originals on platen 2.
In this mode, 01 is placed and exposed.

(b) is the simplex mode, and the document tray 60
2, the originals 601 are stacked with the first side to be copied facing upward. When the start button is pressed, first the first drive roller 605 and the second drive roller 6
07 rotates, but the third driving roller 612 moves upward and separates from the driven roller 613, and the stop game) 6
15 descends and blocks the horizontal conveyance path 611. As a result, the original 601 passes through the arcuate conveyance path 609 and is pressed against the stop gate 615 (■ to ■). This stop gate 6
At position 15, the document is corrected by the skew roller 627 so that its edge is perpendicular to the horizontal conveyance path 611, and the sensors S, -S, -S. The original size is detected.

Next, the third driving roller 612 moves downward and comes into contact with the driven roller 613, and the stop gate 615 rises to open the horizontal conveyance path 611, and the third driving roller 61
2. Belt drive roller 619 and fifth drive roller 6
22 rotates, and the original is sent to a predetermined position on the platen 2 with the side to be copied facing down, exposed, and then ejected. Note that 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, there is also a function of feeding two documents of the same size at the same time (2-U
P), large document feeding function (LDC), computer form feeder (C) for feeding continuous paper for computers.
CF) function.

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

Therefore, the ejected originals are stacked in the order in which they were first stacked on the original tray 602, with the first side to be copied facing downward.

(II-5) Sorter In FIG. 22, the sorter 19 has a sorter body 652 and 20 pins 653 on a movable cart 651. Inside the sorter body 652, a belt drive roller 656 that drives the conveyor belt 655 and its driven roller 657 are provided, as well as a chain drive sprocket 660 that drives the chain 659 and its driven sprocket 661. These belt drive rollers 65
6 and chain drive sprocket 660 are driven by one sorter motor 658. Conveyor belt 655
A paper inlet 662, a paper outlet 663, and a switching gate 665 driven by a solenoid (not shown) are provided at the upper part of the paper. Furthermore, an indexer 666 is attached to the chain 659 for switching and supplying copy paper to each pin. As shown in FIG. 23, the rotation of the drive shaft 671 of the sorter motor 658 is transmitted to a pulley 673 via a timing belt 672.

The rotation of the pulley 673 is transmitted to the belt drive roller 656 and to the chain drive sprocket 660 via a gear device 674.

Next, the operation will be explained with reference to FIG. 24.

(a) shows the non-sort mode, in which the switching gate 665 is in the non-sort position and sends the copy paper to the uppermost discharge tray.

(b) shows the sort mode, in which the switching gate 665 is switched to the sort position, odd-numbered sheets are conveyed from the top to the bottom pins to the odd-numbered pins, and even-numbered sheets are conveyed from the bottom to the odd-numbered pins. It is conveyed to the even-numbered pins toward the upper pin.

This reduces sorting time. (C) and (d
) shows the stack mode, (C) shows an example of 4 copies of 4 originals per original, and (d) shows the case where the maximum number of sheets that can be accommodated per pin is exceeded, for example, when the number of sheets exceeds 50. If this occurs, it is stored in the next row of pins.

■) Full stack (III-1) Features of the full stack control device In the state where the last pin is used, that is, in the full stack state where a predetermined number of copy sheets are ejected to all pins, the full stack message is displayed. Whether it is necessary or not depends on the situation when a full stack occurs and the size of the message. For example, if a full stack occurs and copying is complete and there is no document to continue copying, there is no need to display a message. On the other hand, there is a problem in that the display may confuse the user.On the other hand, if the document is in the middle of copying, it is not possible to continue copying the document while it is in the full stack state. It is necessary to have the user remove the paper and release the pin, and it is essential to display a full stack message.Therefore, the copy operation completion state (copy completed or copying in progress) when full stack occurs. In order to display an appropriate message, it is necessary to determine the full-stack message.The full-stack control device of the recording device of the present invention displays a full-stack message in consideration of the situation when a full-stack occurs. This will be explained in detail below.

(A) Determination of copy operation completion state Whether the copy operation ends with copy completion or in the middle of copying can be determined based on whether there is a document to be copied next. In automatic document feed (hereinafter referred to as ADF) mode, which automatically places the document on the platen,
It can be easily determined whether there is a document left to be conveyed next. However, in a mode other than ADF, for example, when manually placing a document on the platen,
In order to determine the end state of the copy operation, means such as providing a sensor on the platen or detecting the next turn-on of the start button are employed. In addition, ADF mode or AD
Regardless of modes other than F, in stack mode,
(II-5) As explained in the section on the sorter, in the copying machine of this embodiment, when the maximum number of sheets stored per pin is exceeded, the sheets are automatically stored on the next stage pin. If the maximum number of sheets stored per I pin is exceeded at the last pin, the operation will be terminated in the middle of copying regardless of whether there is a next document.

(B) Display Determination As described above, in this embodiment, two types of states are detected as the end state of the copy operation: copy completion and copy in progress. However, when a copy is completed in a mode other than ADF, the physical copy on the copying machine is completed, but it is unclear whether a series of logical copies have been completed from the user's perspective.

Therefore, the display determination of a full stack message is made as follows, taking into account the copy mode information (ADF mode, mode other than ADF) and the copy operation completion state.

(2) When copying is completed in ADF mode The copying operation has completed normally and there is no document to be copied next, so it is unnecessary to display a full stack message. Therefore, the message will not be displayed.

■If copying is in progress in ADF mode, the copying operation has not finished and it is necessary to remove the copy paper from the sorter. Thus, for example, displaying a full stack message such as ``Remove the paper and start again.''

(2) When copying in a mode other than ADF Since the mode is other than ADF, it cannot be determined whether there is a next document, that is, whether a series of copying operations has been completed or is in progress.

In this embodiment, for example, a full stack message is displayed the next time the start button is pressed. As a result, for example, if copying is complete and there is no document to be copied further, the start button will not be pressed and no message will be displayed. Therefore, users are not bothered by unnecessary messages. Also, if you are in the middle of copying, press the start button again, and a message will be displayed to let you know the full stack. Incidentally, before the start button is pressed, the message may be displayed by detecting that the document on the platen has been replaced.

As explained above, the full stack control device of the recording apparatus of the present invention reflects the situation when a full stack occurs in the copy operation end state, and also makes a display determination based on the copy mode information and the copy operation end state, and Displaying.

(III-2) Full stack detection means FIG. 1 shows the configuration of the full stack detection means, which includes an organic sensitive material belt 4, a sequence manager 32, and a sorter 19.
and counters 19a, 19 provided on the sorter 19
Consists of b. Here, the organic sensitive material belt 4 outputs a pitch signal that serves as a reference for starting the carriage based on the number of belt holes and the number of panels. A temporary signal CNEXT PICTHOX CMD) is output to determine whether the pitch of CNEXT PICTHOX CMD can be enabled. When the sorter 19 receives the core alignment signal, it adds 1 to the counter 19a (the number of copies output for the pin currently in use). The counter 19a can count up to the maximum number of sheets accommodated per pin (for example, 50 sheets), and is reset when that number is reached. The counter 19b counts the number of pins currently in use, and is incremented by 1 each time the counter 19a overflows.

For example, if the count value of the counter 19a is 30 (30 sheets of copy paper are stored in the pin currently in use),
When l is added by inputting the timing signal, the count value of the counter 19a becomes 31. On the other hand, counter 19a
When the count value reaches 50, it is reset and the counter 19
Add 1 to b. Here, when the count value of the counter 19b exceeds the total number of pins, 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 sequence manager 32 ejects the copy paper of the pitch currently being copied and stops the operation of the machine in order to invalidate the next pitch. Thereafter, when the operation of the machine is stopped and a sorter standby state (full stack) is entered from the sorter 19, a full stack detection signal is output to a user interface 36, which will be described later. Note that even if the counter 19a is below the maximum number of sheets that can be accommodated when the make-up signal is input, if the document is changed and the document is forcibly moved to the next pin, the counter 19b is set to 1.
is added, and the count value of the counter 19a is set to 1.

The output operation of the full stack detection signal mentioned above will be explained with reference to the time chart of FIG.

To simplify the explanation, assume that a double sorter (two 20-pin sorters connected, so the total number of pins is 40 pins) is used to copy 41 originals one copy at a time.

The first original is placed on the platen, the panel to be copied first is conveyed to a predetermined position, and the organic photosensitive material belt 4
When the pitch signal ■ is input to the sequence manager 32, the sequence manager 32 selects the NEXT PTC
A THOK command is output to the sorter 19 to inquire whether the next pitch is valid, in other words whether there is a pin to eject the next copy. counter 19 of sorter 19
a and 19b are each set to 1 as count values, and the current pitch indicates that the first sheet of paper is stored in the first pin. Upon input of the NEXT PICTHox command, the counter 19a increments by 1 and increments by 2.
becomes. However, since the number of copies is 1 in stack mode, the next pin is used each 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. counter 19b
becomes 2 by adding 1, indicating that the pin scheduled to eject the next copy is the second pin. Here, since the count value indicated by the counter 19b is less than the total number of pins (40≧2), the sorter "19" sends an OK signal to the sequence manager 32 indicating that the next pitch is valid.

Next, when the pinch signal ■ is input to the sequence manager 32, the NE□XTPICTHOK command is output, the counter 19b is added, and the count value indicated by the counter 19b is less than the total number of pins (40≧3), so it is OK.
The signal will be returned twice. Similarly, the sorter 19 outputs an OK multiplied signal for the pitch signals ① to [phase]. Subsequently, when a command <NEXTPTCTHO is input from the sequence manager 32 to the sorter 19 based on the pitch signal [phase], 1 is added to the counter 19b, and the count value becomes 41.
This exceeds the total number of pins of the sorter 19. Therefore, the copy paper ejection pin cannot be secured for the next pitch. In other words, since the sorter 19 is in full stack at the current pitch, it responds with a full stack detection signal and invalidates the 'next pitch. When the sequence manager 32 receives the input of the full stack detection signal ', it stops the operation of the next copying bin, and further discharges the sheet being copied to the final pin, stopping the operation of the machine. At this time, Soak 19 is 40
After ejecting the copy paper to the second pin, the state transitions to sorter standby, and the sequence manager 32
Output standby signal (full stack). When the sequence manager 32 receives the sorter standby signal following the full stack detection signal, it recognizes the full stack state for the first time and displays the user interface (U/I).
Outputs full stack detection signal to.

(III-3) Determination means In this embodiment, the user interface 36 performs full stack display determination as one of its functions, and the display determination based on the above-mentioned copy mode information and copy operation completion state is performed at the timing shown in FIG. As shown in the chart, the sequence manager 3 that constitutes the full stack detection means
This is achieved by checking the full stack display at each point while interfacing with 2.

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

Note that the present invention is not limited to the above embodiments, and various modifications are possible. For example, in the full stack detection means, the sequence manager 32 communicates with the sorter 19 based on the pitch signal to detect a full stack. It may be possible to detect a full stack by managing the display, or it may be possible to make a display judgment at POINT-1 of the judgment means and only display at POINT-2 and 3. There is no particular limitation as long as it has a message display function, such as a panel or the like.

〔Effect of the invention〕

As explained above, according to the full stack control device of the recording device of the present invention, when full stack is detected in the stack mode, the display is determined based on whether the copy operation continues or not, and the display is determined based on the determination result. The full stack message is displayed by the display means.

Alternatively, by not displaying messages, we were able to avoid displaying unnecessary messages that would confuse users, and we were able to display full-stack messages at appropriate times depending on the situation. Moreover, this made it possible to improve the operability of the storage device.
