Further, the copied original is removed from the platen glass 204 by a conveyance belt 205, scooped up by a gate claw 207, and discharged to a document receiver 206 at the upper part of the automatic document conveyance device 200 by a document conveyance roll 208.

When copying work is performed in this manner, each step is performed while detecting the operating state of each device and the paper passing state.

Such an automatic document feeder 200. In a copying machine equipped with peripheral devices such as the sorter 300, the operation of each device must be controlled in relation to the status of other devices, so the main body of the copying machine and each peripheral device must be connected through a communication path.

The electric circuit board 23 of the automatic document feeder 200 is used as communication data.

Further, the electric circuit board 133 includes a level converter 45.
, a personal computer 47 is connected via a human output interface 46.

FIG. 51 shows the general arrangement of the simulator kit 40 and peripheral equipment.

Inside the rack 400a on the left side, there is a display panel section 42.on which the layout of the copying machine is schematically drawn. Copy machine main body 100

A switch panel section 41 for manually inputting signals and a stabilized power supply 48 for supplying operating voltage to each section are arranged. Furthermore, a personal core heater 471 output interface 46 and a level converter 45 are arranged in the rack 400b on the right side. Note that the personal computer 47 and its related devices will be described later.

As shown in FIG. 52, the display panel section 42 schematically depicts the layout of the copying machine to be developed so that the flow of paper during copying can be visually grasped.

For example, in the figure, 401 indicates a photosensitive drum, 402 a fixing device, 403 a conveyance roller, and 404 a paper feed tray. Also, document feeder F? At the location corresponding to 200, there is a display 405 corresponding to the conveyor belt 205.
etc., and the location corresponding to the sorter 300 has a bin 30
There are displays 406 and the like corresponding to 1.

Furthermore, the display panel section 42 includes a plurality of blue lamps 42a that display outputs from input components such as various sensors.

As mentioned earlier, the personal computer 47 is connected to the electric circuit board 133 via the human output interface 46 and the level converter 45 (f
f! (See Figure 50). The timing data and communication data from the personal computer 47 are branched into a predetermined number of signal paths by the input/output interface 46, adjusted in level by the level converter 45, and supplied to the electric circuit board 133. The timing data, relay and communication data mentioned above are for simulating signals from each sensor and other peripheral devices. Further, the status of the signal output from the electric circuit board 133 is displayed on the console of the personal computer 47.

A simulation using a simulator system including such a simulator kit 40, a personal computer 47, etc. will be described.

This simulator system has a manual control mode and a personal computer control mode.

In manual control mode, it performs transmission/reception simulation, sensor signal simulation, etc. In the transmission/reception simulation, data input from the keyboard of the personal computer 47 or initially loaded data is transferred to the electric circuit board 133.
The data transmitted to the electronic circuit board 133 and received from the electric circuit board 133 are displayed on the console of the personal computer 47.

As described above, the sensor signal simulation is to set a signal to the electric circuit board 133 by turning on and off the switch 41a of the switch panel section 41, and to display the state using the blue lamp 42a.

Further, the state of the output signal from the electric circuit board 133 is displayed by a red lamp 42b.

In personal combination coater control mode, electric circuit board 1
This is used when debugging the H.330 control software and performing paper running tests, etc. according to timing charts. Here, communication data, sensor signals, etc. are created based on a timing chart described later.

Here, the paper running test will be explained.

When developing a copying machine control program, it is necessary to check how the program is executed depending on the paper transport position as the paper is sequentially transported inside the copying machine.

At this time, since the actual mechanical part is generally not yet completed, timing data simulating the output of the sensor, for example, is prepared, and the program is executed based on this timing data.

That is, in the in-circuit emulator 44,
Switch panel section 41 or personal computer 4
C of the target while supplying various sensor signals from 7.
By running the same program as P U132 and observing the operating status of the copying machine expressed by the blinking of the lamps 42a and 42b on the display panel section 42, it is checked whether the program is operating normally. . If the operation is abnormal, the faulty part of the program is estimated from the flashing states of the lamps 42a and 42b, and the error in the program is detected using the in-circuit emulator 44 and corrected.

Additionally, a logic analyzer is used to inspect timing data, and an oscilloscope is used to inspect the actual waveforms of each part. Additionally, these tests may be performed in combination.

An example of the above-mentioned simulation will be explained using a simple program example.

The program below will run fsrout-ro when the sensor named fusin-snr is turned on.
This is a routine written in the PL/M language that turns on the operational switch named ll and turns off the operational switch named reg-sol.

All programs are written in uppercase letters. For example, FUSIN-3Nfl in the program is written as fusin.
-means snr. The same applies to other notations. Also, fusin-snr is a sensor that detects when paper comes to the entrance of the fuser, and fsrout-roll
is the roller operation switch at the exit of the fuser,
reg-sol is an operation switch that opens and closes the registration gate.

IF INF$8255scIIK (FUSIN-SN
I+)=ON THENDO; FSROUT-ROLL-ON; RIEG-SQL-OFF; END.

A flowchart of this process is shown in FIG.

That is, this routine generates INF$82 per period.
55 Start a subroutine named CHK to check the output of sensor fusin-snr, and when the paper reaches the inlet of the fuser, operate the roller at the outlet of the fuser and turn off the registration gate. This process is performed to stop the paper from passing through.

When checking the operation of this routine, a sensor signal corresponding to the sensor fusin-s port is supplied to the electric circuit board 133 of the personal computer 47 of the simulator system while the above program is running.

If the routine is programmed correctly, fu
Immediately after sin-snr is turned on, fsrout-r
oll's red lamp 42b3 lights up and reg-s
The red lamp 42b of ol goes out. Further, at this time, the fusin-snr blue lamp 42a3 is lit.

However, if there is a bug in the above routine and, for example, you accidentally program REG-SQL-ON; instead of REG-3QL-OFF;, even if fusin-snr is turned on, the light will not turn off. Since the red lamp 42b2 of reg-sol remains lit, it is clear that an abnormal operation is occurring.

When debugging software in this way, it is necessary to prepare data indicating the operating state of the copying machine, that is, a sensor signal corresponding to the sensor fusin-snr in the above example.

For this reason, in the past, changes in sensor output were determined on graph paper based on the positions of various sensors in the actual copying machine, paper conveyance speed, etc., and an input chart was created.
Timing data was created from this input chart. An input chart is one in which time is plotted on the horizontal axis and sensor output level is plotted on the vertical axis.For example, it shows how the sensor output changes over time as the paper progresses. It is expressed. Timing data corresponds to the input chart, but in order to be used for actual simulation, the timing data and change state of change points are recorded using raw data such as AS.
It is expressed in CII code.

First, when creating an input chart, prepare graph paper with time on the horizontal axis and distance traveled by the paper on the vertical axis, and as shown in Figure 54, the leading edge of the paper moves over time. and the position of the trailing edge according to the paper size, and hand-draw a straight line representing the state of paper movement. In the figure, LEI is a line segment indicating the moving state of the leading edge of the first sheet, and LEI is a line segment indicating the moving state of the trailing edge of the same sheet.

Similarly, line segment LH2 indicating the front and rear edges of the next sheet

Next, a horizontal line S1.1 is drawn from the vertical axis position corresponding to the installation position of the sensor named fusin-snr. Then, the line segment LED, T[El, LE2. T.I.
Find the point where E2 crosses the horizontal line SLI and find the change point of the sensor output 1. ．． 1. .

Find t6+t7. Next, from these change points, the change in the output of the sensor fusin-snr is written by hand using binary values of high level and low level to create input chart C1. In addition, the sensor fus

Find and create input chart IC2.

Next, when creating timing data from the input charts IcI and IC2, visually check the change direction of the input charts HCI and IC2, the duration from the previous change point, etc., and make sure that the timing data can be used in the program of the personal computer 47. Create a data statement. That is, at each change point, a data statement as shown below is created in chronological order, and this data statement is entered from the keyboard of the personal computer 47 and stored as a file on the personal computer 47Q.

DATA Duration time, ``Signal type'', Signal number, ``Signal status'', ``Message'' For example, the input chart in Figure 54) In the case of IC2, the data at time t1 is DATA t++ ``I'', n

+, “Bi’, n ++” H”, “FLISIN
-3NR” data at time t3 is DATA t 3 t 2.”I ”, n,
, "L", "FUSIN-5NR".

Note that the signal type 1 is an input signal, and the signal number nl+n2
is the sensor fusin-snr in advance.

The number assigned to rcg-snr and the signal state of H indicate high level and L indicate low level.

In this way, at each change point, a necessary number of data sentences are created and input into the personal computer 47.

In simulation 1, a signal of a predetermined level is generated at a predetermined time based on this data statement stored in the personal computer 47, the level is adjusted by the level converter 45, and then a signal of a predetermined communication path is generated. A simulation is performed by supplying the signal to the electric circuit board 133 as a high-level or low-level signal.

[Problem to be solved by the invention]

However, since all of the work to create this input chart is done manually, there is a problem in that it takes a lot of time and effort to create. In addition, since the work is done visually, reading and filling errors are likely to occur.
It was difficult to create accurate input charts. Therefore, there is a problem in that timing data for simulation cannot be prepared in a short period of time, and as a result, the entire debugging work is delayed.

Copying machines have various combinations of operations depending on the copy magnification, paper size, number of copies, paper path, original input method, paper output method, etc., so there are various types of test modes to check the operation in these combinations. For example, there are hundreds of possibilities. Therefore, it is practically impossible to create an input chart that corresponds to all modes, and in reality, only a few limited modes can be simulated.

Furthermore, when a very large number of copies (approximately 1,000 copies) is set, it is impossible to create an input chart that corresponds to all the sheets.

The present invention was devised to solve the above-mentioned problems, and an object of the present invention is to accurately and easily create input charts for simulation in a short time.

[Means to solve the problem]

In order to achieve the above object, the impact chart creation device for image output device simulation of the present invention provides paper state data indicating the state of paper conveyed within the image output device and a paper sensing device disposed within the image output device. data input means for inputting part position data indicating the position of the part; and an input signal output from the paper sensing part when the paper passes through the paper sensing part based on the paper state data and the part position data. and an image output means for generating an input chart corresponding to the waveform of the input signal from the timing data and outputting the input chart as an image. It is characterized by

It is desirable to provide a file means for storing the timing data obtained by the arithmetic means in order to improve the efficiency of editing work.

[Effect]

The operation of the present invention will be explained by giving a concrete example with reference to the principle block diagram of FIG. 1, the flowchart of FIG. 2, and the explanatory diagram of FIG. 3.

In the present invention, for example, a change point P in the conveying speed of the leading edge of the sheet conveyed from the data input means such as a keyboard or mouse shown in FIG. 1 within the image output device,
The xY coordinate data of P, P, P, (see FIG. 3) is input to the calculation means as paper state data (step 5101). In the calculation means, these
A line segment LE connecting each change point is calculated from the Y coordinate data. And the line segment LE representing the front edge of this paper
is displayed on image output means C such as a graphic display (step 5102). Here, if the paper size is input to the data input means (step 5103
), a change point P of the line segment LE representing the front end by the calculation in the calculation means, P2. The value of the Y coordinate of P,, P4 is subtracted according to the paper size, and the change point Q of the trailing edge is
,, Q2. Q.

The coordinates of Q are found. Then, a line molecule IE representing the movement state of the trailing edge of the paper is displayed from these coordinates (step 5104). Furthermore, when part position data indicating the position of paper sensing parts such as sensors is input to the data input means (step 5105), the Y coordinate Y is determined based on this part position data, and the image is displayed on the image output means C. The input signal line SL is displayed in the horizontal direction (step 5106). Then, the X coordinates X, . Konoza 1'A X
, to x2 represents the sensor output, and since the initial state of the sensor output is set to low level here, it changes from low level to high level at the time when input signal line SL intersects line segment LE, It changes from high level to low level again at the time when it intersects line segment LH (step 5108). Here, the information on each change point is stored in a file means such as a disk device as data on the elapsed time from the previous change and data on the state of change (step 5109).

Based on these data, the calculation means B calculates an input chart NC indicating a change in the level of the signal output from the paper sensing component when the paper passes through the paper sensing component, and outputs an image. displayed on means C (step 5IIO).

Note that data creation can be made more efficient by reading and editing the data stored in the file means and then storing it again as a new file.

FIG. 5 shows the software configuration of the input chart creation device of this embodiment.

There is a data creation block DG port under the UN IX operating system SYS of the VAX-11/750, and this data creation block DG13 creates the hardware information file HIF and the diadem file OF.
, input chart file ICF, serial chart file S[F, timing chart file T
CP, composite timing chart file 5TCF,
Each file such as timing data creation file TDF, timing data format file T, +FF, etc. is referred to.

FIG. 6 is an explanatory diagram showing the relationship between each of the above-mentioned files that store data and each table that is referred to during this storage operation.

When specifying the model (step 5201) and specifying the module (step 5202), both the IJ path table WDPT and the model selection table PST are referenced in each step.

Furthermore, when setting hardware information (step 5203), the hardware information file 111 F and hardware information table HIT are referred to.

Also, diagram creation (step 5204), input chart creation (step 5205), serial chart creation (step 320G), timing chart creation (step 52)

When synthesizing timing charts (3208) and creating timing data (5209), basically the following information is used: diagram table DT and diagram file OF, input chart table ICT and input chart file ICF, serial chart table SCT and serial Chart file SCF.

1. The processing flow of the main program in the siminilation apparatus of this embodiment will be explained with reference to the flowchart of FIG.

A data creation program stored in the disk device 6 (see FIG. 4) is loaded into the main memory 2 via the CPU 1, and this program is activated.

This data creation program runs on a directory with a tree structure, and in this embodiment, multiple directories at the model level are located under the directory named sim, and further directories at each model level are located below the directory named sim. Multiple module-level directories are located under the directory. Furthermore, each file described later is located under each module level directory. In order to manipulate these files, each file is given an IJ pathname.

This working directory bus salt is a parameter that determines which file in the UNIX file system is to be operated on. For example, if the IJ bus name is /a/b/c and you specify a file named X, the actual file will be named /a/b/c/x, It is judged to be below b/c.

When the data creation program is started, the directory below the sim is read (step MPI), and the target model name is displayed in menu format on the screen of the graphic display 5 (step MP2).
. In other words, the already registered model name is model number m, r2J.
, r3J, . . . For a new model, enter "0" to proceed to module configuration registration (Step!, IP3. MI+4. MP5).

This module configuration registration (step MP5) is used to register the model name and its module configuration in the case of a new model.The module number is automatically displayed when the name of the developed model is entered, so it is compatible with this. and enter the module names in order to register the module configuration. In this way, a new model-level IJ is created, and a module-level directory is created under it.

In this embodiment, the copier has several modules.

It is divided into 2 modules, and a module name is registered for each of these modules. Note that a module here means one functional part of a copying machine controlled by one CPU, and for example, the copying machine main body, automatic document feeder, sorter, etc. are each considered to be one module.

The reason for dividing into a plurality of modules in this way is to reduce the load on the CPU per module, eliminate waste, and further improve efficiency during program development.

For example, if a single CPU is to control peripheral devices, control programs must be created for all the peripheral devices that may be used. However, since the automatic document feeder, sorter, etc. may not be installed, there will be unnecessary parts in the control program and the operation speed will be slow.

Also, since it is necessary to create a control program that commonly controls all peripheral devices, the program is i! J2 It becomes large and huge, making debugging extremely difficult.

Furthermore, when the specifications of a peripheral device change, it is necessary to modify the control program, but it is difficult to maintain consistency with other parts when making this modification. There is also the possibility that new bugs may occur in other parts.

Therefore, in this embodiment, the system is divided into a plurality of modules according to function, and each module is controlled by an independent CPU so as to be compatible with a copying machine. By doing so, it is possible to create and debug programs independently, thereby increasing development efficiency. That is, when a module is operating abnormally, it is basically sufficient to perform an inspection within the module, so it is easy to investigate the cause of the abnormal operation.

In addition, even if the specifications of peripheral devices have changed,
Since all you have to do is modify the program of the device, it is easy to modify and does not affect other modules. Never give up. Furthermore, since the load on each CPU is reduced, operation becomes faster.

Here, for example, in the copier itself! , 1 person IN, the automatic document feeder is named 80F, the sorter is named 5ORT, and the paper feeder is named CHM. Please note that when entering the module name, you will be required to enter it twice.
The module name is registered only if the same module name is entered each time. This is because if an incorrect module name is registered, the incorrect module name will be added to all data in subsequent processing.

After completing the module configuration registration (step MP5) i4 described above, the work directory bus table W shown in FIG.
Add the IJ bus name to DPT (step IA I'6).

If the target model is a registered model, proceed directly to adding a work directory bus (step MP3. MP4゜'
AP6). Here, the model name is added, and the working directory path is structured as sim/model name.

Next, the module names are displayed in a menu format (step M P7 ), and the desired module is selected from this module menu by number.

Next, add the working directory path, i.e. the module name here (step 1.1 I'8
), the working directory path has the following structure: sim/model name/module name. By adding this module name, the user specifies which module's test data is to be created.

Next, a session block menu is displayed (step MP9), and a desired session block is specified (step 1.1 P l O). Here, inputting rlJ from keyboard 4 selects hardware information setting (step MP12), inputting "2" selects timing data creation (step MP13), and inputting "3" selects timing data format conversion (step MP12). Step!, I P l 4 ) is selected and the selected session is activated. In addition, “4
” to return to the UNIX system.

As shown in FIG. 8, the processing in the input chart creation device of this embodiment includes hardware information setting (step MP12) for setting various conditions corresponding to the hardware of the developed model, and movement of paper within the copying machine. Timing data creation (step M P ] 3) that virtually creates timing data that is sequentially generated according to the timing data, etc., and a timing data format that converts this timing data into a format that can also be used in other devices, such as a simulator kit. It is divided into three sessions of conversion (step MP14).

The reason for dividing this into three sessions is to improve operability by grouping related operations together.
This is because it becomes easier to create the software for the simulator itself.

Each session will be explained in detail below, but in order to make the overall relationship clear, it will be divided into three sessions as shown below, and each session will be further divided into multiple sections. ).

(I) Hardware information setting session, input signal name setting, output signal name setting, reference clock setting, reception data definition, transmission data definition (II) Timing data creation session, diagram creation, input chart creation, serial chart creation, timing Chart Creation/Timing Chart Synthesis/Timing Data Creation (Ill) Timing Data Format Conversion Session Note that each process in the timing data creation session is shown as being serially processed in FIG. After completing the process, if you give an instruction to skip that process, you will be returned to the main menu of the timing data creation session, and you can select each process as you like.

Each session will be explained in detail below.

(I) Hardware information setting Here, hardware information table 1f shown in FIG.
rT, various hardware information necessary to create timing data, such as input and input of switches, sensors, motors, etc. used in the copying machine shown in FIG.
Define the output signal name, reference clock, and communication data.

This processing flow is shown in FIG.

As shown in the figure, this hardware information setting session is further divided into the following five subsessions.

In other words, input signal name settings to register input signal names of sensors, switches, etc., output signal name settings to register output signal names of solenoids, motors, etc., and to convert real time to blackout value during timing data format conversion described later. Reference clock setting.

It consists of five subsections: reception data definition, which defines the data received from the external module, and transmission data definition, which defines the data sent to the external module.

When you enter the hardware information setting session, each of the above subsections is displayed in menu format (step 11).
11) Therefore, select the subsessions to be started from "1" to "5".
” (step 1112). This starts the specified subset (step 1 (14)
~II + 8).

First, the input and output signal name setting subsection (steps 1114 and 1115) will be explained. Here, input signal names and output signal names are input from the keyboard 4 in correspondence with input signal numbers and output signal numbers. for example,
In the example shown in FIG. 52, the sensor that detects when paper has arrived at the fuser is named fusin-snr, and the roller operation switch at the exit of the fuser is named fsrout-r.
The operating switch for opening and closing the registration gate is named reg-sol.

Next, the reference clock setting subsection (step 11
16) will be explained.

This is used to set the cycle of the clock used in the copying machine, and is used to convert time into a clock value when converting the format of timing data as described later. Here, the long-lock period is input from the keyboard 4 in units of μS, for example.

Next, the reception data definition subsection (step +11
7) will be explained in detail.

This reception data definition subsection includes the serial base data definition (step 530), as shown in FIG.
1), Serial data relational expression defined @ (step 5302)
, serial data table definition (step 5303), and serial data repetition definition (step 5304).

Each function will be explained below.

The serial base data definition function defines the correspondence between data and its raw data value (in hexadecimal representation).

The procedure is to input the serial communication data name and data from the keyboard 4. For example, for the serial communication data name 5TAIIT, r8301100000
", and data "82" is defined for the serial communication data name 5TOP. As a result, these data are supplied to the minicomputer system 8 and stored in the hardware information file 111F shown in FIGS. 5 and 6.

By defining the serial communication data used in the timing data in this way, it is also possible to create communication data from other modules. Note that in order to make the communication data more versatile, a variable n that depends on the number of feeds can be introduced into the communication data as a variable. For example, the serial number 1NTRUPT
For the data name, "variable n 030010n100J"
It is possible to define data containing .

The serial data relational expression definition function uses the signal INTR described above.
Like IIPT, when there is a variable n in the serial data, the variable is defined by the number of feeds F.
For example, it is defined as n=3+F. Note that the number of variables is not limited to n, and a plurality of variables can be set.

The serial data table definition function defines variables that are difficult to define in the form of an equation such as n=3+F, which depends on the number of feeds F, in the form of a table. That is, data at a predetermined position can be set by specifying the variable P to be set and the number of feeds F and inputting the data.

For example, when defining a serial data table, a display as shown in FIG. 10(a) is displayed on the graphic display 5, and the first serial data is r02.
It can be seen that it is defined as 0c 0301 d2 d3J. Note that "02" in the display indicates that the number of feeds is 1, and the same < rOcJ 03" indicates that the number of feeds is 2 or 3. Here, keyboard 4
From rP=1. F=7.3cJ, rP=1.
F=3.2ct, rP=1. If you enter F=9.5aJ, the first serial data will be r020c 030f d2 d3, as shown in ff1lo, etc.
Newly defined in 3c 2c 5aJ. The variable P defined here is r
Ill:]Q[11 (11”, 3100J). However, Po is PI, P2.

The last serial data repetition definition function defines the law of data repetition in the serial data table definition, and is additionally used to define variables that change periodically for each number of feeds.

When defining this serial data repetition, the same display as when defining the serial data table is performed, but here, input of the variable P containing the data to be repeated and the feed value F is required, so it is necessary to input the variable P that contains the data to be repeated, so Specify the start and end positions of the data section.

The above is an explanation of the reception data definition function.
The transmission data definition function also has a similar function.

The data set or defined in each subsection of input signal name setting, output signal name setting, reference clock setting, reception data definition, and transmission data definition described above is stored on the hardware information table in the format shown in FIG. 11. will be expanded to.

This hardware information table is shown in Figure (a).
As shown in Figure (b), it is broadly composed of the following areas: input signal name, output signal name, reference clock, reception data, and transmission data. The input signal name is composed of an input signal name, and the output signal name is composed of a plurality of output signal names as shown in FIG.

Further, each area of received data and transmitted data is serial base data and serial review type, respectively, as shown in FIG.

It consists of a serial data table and a serial data repetition area. These data are then stored in the disk device 6 as a hardware information file 111 F in the format shown in FIG.

The old hardware information file F roughly corresponds to the hardware information table IIIT, and as shown in Figure (a), broadly speaking, it contains management information, input signal name, output signal name, reference clock, reception It is composed of each area of data and transmission data, and the management information includes the number of input signal names, as shown in FIG.

It consists of the number of output signal names, the number of received data, and the number of transmitted data.

The reason why the hardware information setting session is divided into five subsections as mentioned above is that each subsection has no dependence on each other and can be configured independently.
This is because it is convenient for operation and because the upper part of the program is convenient.

(n) Timing data creation This is to actually create timing data using the information set in the hardware information setting session described above (step MP13).

As shown in Figures 6, 8, and 13, this session consists of (1) Diagram creation, (ii) Input chart creation, (iii) Serial chart creation, (iv) Timing chart creation, (V )
It consists of six subsections: timing chart synthesis and (vi) timing data creation.

Each subsection will be explained below.

(i) Diagram Creation This involves creating a timing diagram, which will be the basis for creating input data, using the mouse 4a or keyboard 4. FIG. 14 shows an outline of the main flow of the process.

When you enter the diagram creation session, a list of registered diagrams is displayed in a menu format on the graphic display 5, so select whether to collect the registered diagrams or create a new one (step DGI,
DG2). If creating a new one, enter "0" instead of the diadem number.

When creating a new item is selected, the screen of the graphic display 5 shown in Fig. 4 shows the horizontal axis as time (in ms) and the vertical axis as the paper movement position (in mm) as shown in Fig. 15. ) is displayed (step 0G7), the diagram table DT is initialized (step 0G8).

Diagram table Kano T has the configuration shown in FIG. 16, and has a specified or selected diagram name,
File creation date, X magnification without showing the magnification in the X-axis direction, i.e. time reduction/enlargement, 7 magnification without showing the magnification in the Y-axis direction, i.e. position reduction/enlargement, Front end registered in this table number of pieces.

Write down the front end table address, the number indicating the number of input data, the input signal name table address having the line system information table address of the input data, etc. 1. It has a region of α. Also, the front end table LIET and input signal name table l5N referenced by this diagram table DT.
T (see FIGS. 17 and 18) is provided. The front end table LET is composed of a front end information table LEIT corresponding to the starting point of the front end and a change position table CPT, and the front end information table LBIT includes a forward address, a reverse address 1, the number of rear ends, a rear end table address, It has an area for storing the @ end number, front end table next address, etc.

Further, the change position table CPT is a forward direction address.

Record the reverse direction address, XY coordinates, etc. 1. It has an area for a. Note that the X coordinate indicates time information, and the Y coordinate indicates position information.

FIG. 19 is an explanatory diagram schematically showing how each of these tables is referred to.

The diagram table OT refers to the first front end information table LEIT, and this first front end information table LEI
T refers to the change position table CPT in which the coordinates of the front end or rear end of the first sheet are written 1 and α. Further, when dealing with a plurality of sheets, the next leading edge information table LEIT in which information on the leading edge and trailing edge of the next sheet is recorded is referred to. In FIG. 19, LEI indicates the front end information section, and TIEI indicates the rear end information section. Details of this reference operation will be described later.

Diagram table D shown in FIG. 14 mentioned above
By initializing T, an area for this diadarum table is secured in the main memory 2, and a predetermined initial value is set in the numerical area of each area, and a blank is set in the character area.

If you want to edit an existing diagram, do the same as above.
As shown in FIG. 14, the standard template is displayed and the diagram table is initialized (Step I).
G3. DG4). Next, data is read from the diadem file OF, which will be described later, and displayed (steps DG5 and DG6).

In either case of creating a new diagram or editing an existing diagram, proceed to diagram editing (step DGIO) described below. Note that when the editing is finished, the process directly proceeds to update the file (step DG9. DGII).

These diagram edits and file updates will be described in detail below.

In diagram editing (step 0GIO>), a diagram is created by combining line segments on the above-mentioned standard template.This template and the program for forming each line segment are created using the minicomputer system shown in Fig. 4. 8, and a graphic command called, for example, CM code from this minicomputer system 8 is supplied to the graphic display 5 via the serial data line 3a.Then, in the graphic display 5,
The graphics command is interpreted and a predetermined figure is drawn.

The general procedure for editing a new diaphragm will be described below with reference to the flowchart of FIG. 20.

In this embodiment, in order to improve operability during editing work, commands to be executed are displayed on the screen of the graphic display 5, and each command is executed by selecting it with the mouse 4a. There is.

That is, the CPU 1 always knows the current position of the mouse 4a (step DGIOI), and obtains the position of the mouse 4a when the operator presses a button on the mouse 4a, that is, the mouse input position. (Step D
G102). Then, commands are determined from this mouse input position (step DG103), and each command is executed (step DG104) to create a line segment.

While each of these commands is executed, information on each changing point of the front end is stored in the diagram table D described above, as described later.
T format is recorded in the main memory 2 and displayed on the screen of the graphic display 5.

Details of each command will be described later.

In step DG105, it is determined whether there is an instruction to finish creating the front end, and the steps DGIOI to DG105 described above are repeated until the creation of the necessary front end line segment is completed.

When inputting the front end or instructing the end of creation, step D
Proceeding to G106, input of the paper size is requested, so input the paper size in mm from the keyboard 4. For example, if the paper size is Δ4, input r210J.

As a result, the paper size is subtracted from the Y coordinate of each change point at the front end of the mini computer stem 8, and the coordinates of each change point at the rear end are obtained (step DG107).

The coordinates of each point at the rear end thus determined are recorded in the main memory 2 in the form of the diagram table DT described above. Then, the line segment of the rear end is automatically added and displayed based on the information on the rear end (step DG10B).

Next, the input signal name of the input signal line required to obtain timing data is input, and the position of the input signal on the paper bus, that is, the Y-axis coordinate is input (step DG109). As a result, the input signal line is displayed at the specified position along with its name (step DGIIO>).

Repeat this process as many times as necessary (step DGIII,
DG109. DGIIO) Input all input signal lines.

When inputting the input signal lines is completed, the diagram editing work is completed.

After editing the diagram table D
The diadarum file OF is updated according to the contents of T.

This updated file is stored in the disk device 6 (
(See step DGII in FIG. 14).

An example of the structure of this diadem file OF is shown in FIG. 21.

The diadarum file OF roughly corresponds to each table in FIGS. 16 to 18, and as shown in FIG. It consists of input signal name information.

As shown in FIG. 6(b), the management information is based on the file creation date, the number of front end/rear end information, the number of input signal name information, and a plurality of front end/rear end management information. Furthermore, each front end/rear end management information is comprised of a number of front end information and a number of rear end information, as shown in FIG. In addition, each front end/rear end information shown in FIG.
As shown in (C) of the same figure, each is composed of leading edge information and trailing edge information, and these leading edge information and trailing edge information are each divided by X in ms as shown in (f) of the same figure. It consists of coordinates and Y coordinates in mm. Furthermore, each input signal name information is as shown in FIG.
It consists of the input signal name and the length in mm indicating the position of the input signal line.

These file data are transferred from the diagram table DT stored in the main memory 2 to the disk device 6.

Therefore, as shown in the flowchart of FIG. 14 above, the diadarum file OF can be called from the disk device 6 (step 0G5), and a diadarum can be created based on these data, which can be engraved and the above-mentioned data can be created. It is also possible to edit it by operation (step DGIO) and store it in the disk device 6 again (step DG1.1).

This editing work can be similarly performed for each file described below.

Next, each command for forming the front end line segment will be explained with reference to FIG. 15 and FIGS. 22(a) to (0). In this embodiment, various commands are provided in order to improve the efficiency of creating and editing a diadem.

As shown in FIG. 15, various command sections for editing are displayed around the screen of the graphic display 5, and by selecting these command sections with the mouse 4a, a predetermined command can be executed. let

When the mouse command section C1 (displayed as Mouse in the figure) at the top of the screen is selected, input is performed using the mouse 4a, and the keyboard command section C2 (displayed as Key-boa in the figure) is selected.
rd) is selected, input is performed using the keyboard 4. In addition, in the initial state, input is performed using the mouse 4a, and in the following explanation of editing work,
Unless otherwise specified, selection means selecting a command section displayed on the screen with the mouse 4a. Further, when the cancel command section CO is selected, the input command is canceled.

The line segment representing the diadarum is basically created by the two-point designation method or the angle designation method, which will be explained below.

In the two-point designation method, after selecting the two-point designation command part C3 (displayed as Draw point L in the figure) displayed on the screen, use the keyboard 4 to select the starting point P1 and ending point P2 shown in FIG. 22(a). Enter the coordinates of or
A starting point P1 and an ending point P2 are specified on the screen using the mouse 4a. The data of the input starting point P1 and ending point P2 is 2.
It is supplied to the CPU 1 via the bus 3 together with data indicating that the point designation method is designated, and is stored in the main memory 2 as front end information.

These data are shown in diagram table D in Figure 16.
1 is written in a predetermined place in the front end information table LBIT and the changed position table CPT in FIG. 17. That is, each time the coordinates are specified, the front end information table LEI
Increasing the number of changes in the front end of T and changing position table C
The PT area is secured, and the locus and ring data are sequentially stored in the change position table CPT. Further, the head address of this newly secured table is stored in the front end information table 1.61T as the front end table next address. Furthermore, the changed position table CPT includes a forward address for specifying the next changed position table CPT and a reverse address for specifying the previous changed position table CPT or front end information table LErT. Be @ed.

Therefore, by sequentially referring to these tables in the direction of the arrows as shown in FIGS. 17 and 19, the coordinates of the changing points can be sequentially identified.

Based on these data, the CPU 1 generates a graphic command that connects the starting point P1 and the ending point P2 with a line segment, that is, a straight line command, and this straight line command is sent to the graphic display 5 via the serial data line 3a. A line segment is drawn between the starting point P1 and the ending point P2, as shown in FIG. 22(a).

Also, the angle specification method is to use the mouse 4a, keyboard command section C2, angle specification command section C4 (1 in the figure)
rad), select the starting point P from the keyboard 4.
When the coordinates and angle θ of point P1 are input, data is exchanged with the minicomputer system 8 as in the two-point designation method as shown in FIG. 22(b), and a diagonal line starting from point P1 is drawn. It will be destroyed. Note that here, the paper conveyance speed is input as the angle O in units of mm/ms. In addition, when inputting from the mouse 4a, after selecting the mouse command section CI and the angle specification command BC4, input the coordinates of the two points P1. P
When 2 is input, a straight line starting from Pl and passing through point P2 is drawn as shown in FIG. 22(C).

Note that when this angle specification method is selected, the end point is not specified, so it is necessary to delete unnecessary parts using the deletion command described below.

This deletion command deletes any part of the specified line segment.
select), target line segment, deletion command part C6
(Displayed as I] e l e t e in the figure) in sequence, select 2 points PL from the mouse 4a or keyboard 4,
By inputting the coordinates of P2, the line segment between the two points is deleted as shown in FIG. 22(d). In this case, the coordinates of the newly formed starting point P2 and ending point P1 are calculated by the mini-computer system 8 and stored as front end information.

In each of the edits described below, the coordinate information is updated by the edit and written in the mini computer system 8 as 1, α
be done.

Also, instead of inputting the coordinates of two points, select the positive direction deletion command section C7 (displayed as +Delete in the figure) or the negative direction deletion command section C8 (displayed as -Delete in the figure) for one of them to specify the point. In this case, all line segments starting from one point in the positive or negative direction are deleted. Note that if negative direction deletion is specified for the starting point side and positive direction deletion is specified for the end point side, the entire line segment will be deleted.

The X-direction copy command section C9 (displayed as [opy X in the figure) is for copying a line segment in the X direction.
After selecting 9 in sequence, use the mouse 4a to select (e)
An arbitrary point P1 on the target line segment and the copy destination point P
By specifying 2, the line segment is copied as shown in FIG. 8(f). That is, the coordinates of a new front end corresponding to the specified point are calculated by the minicomputer system 8, added as new front end information, and sent to Note 1.

The Y-direction copy command section Cl0 (indicated as Copy y in the figure) is for copying a line segment in the Y direction, similarly to the X-direction copy command section C9 (Fig. 22 [(to), (h)
reference).

X direction movement command part C11 (5hift
), Y direction movement command section Cl2 (displayed as 5hift
(displayed as V) moves a line segment in the X direction and Y direction, and specifies the same as the X direction copy and Y direction copy (
Figure 22 (i), (j) and (k), (1)
reference).

Offset copy command section C13 (in the figure, Copy o
ff) copies a line segment in the X or Y direction, but in this case, the copy destination position is specified by an offset amount.

The operating procedure is to sequentially select the selection command section C5, the target line segment, and the offset copy command section C13 on the screen, and then input offset (l) from the keyboard 4. As a result, the line segment is copied at a position offset by the -foot opening, as shown in FIG. 22 (e).

Offset movement command section C14 (5hift in the figure)
(displayed as "off") moves a line segment in the X or Y direction, and the operating procedure is the same as offset copying.

The shaping command section C15 (indicated as 5hape up in the figure) is for combining a group of discontinuous line segment fragments and shaping them into a negative line segment.

For example, if there is a discontinuous line segment as shown in FIG. It becomes one continuous line segment as shown in 0).

The panning command section C16 (indicated as Pan in the figure) moves a specified point to the center position on the XY coordinate space. After selecting the panning command section C16 on the screen, by specifying the point executed. For example, the overall XY coordinates are Qms~232m.

It has a size corresponding to -5000mm to +5000mm, and in the standard state, oms to 4000m5
, o mm to 2000 mm, but by coordinate transformation, display centered on an arbitrary point becomes possible.

Input setting command section C17 (in the figure, Input set
) is used to input an input signal line indicating the position of the input signal on the paper path. Select the input setting command section C17 and input the input signal name and Y coordinate value from the keyboard 4. The input signal name thus input is stored in the input signal name table together with the forward address, reverse address, and length, as shown in FIG. Based on these data, input signal lines are drawn at predetermined positions on the screen.

Input deletion command section Cl8 (Input del
) is for deleting the input signal line indicating the position of the input signal on the paper bus, and by sequentially selecting the input deletion command section C18 and the desired input signal line, the input signal line is deleted.

Also, r Xi/2. X115.
X2.

×5” is the scale factor part CI9. [:20 is shown, and when you select any magnification with the mouse 4a,
Alternatively, the image is displayed enlarged or reduced by 2 times, 5 times, 172 times, or 175 times in the Y direction. The magnification set here is the first
It is stored in the diadarum table opening T in Fig. 6.

Next, see the flowcharts in Figures 23(a) and (b) and the display examples in Figures 24(a) to (e) for a simple example of creating the front end of a diadarum using each of the above commands. and explain. Note that the numerical value at the lower right corner of the screen indicates the coordinate position of the mouse 4a.

First, use the mouse 4a to select, for example, a two-point designation command section C.
Select 3 to start the 2-point designation command, step DG
301), the coordinates of both ends of the line segment element at the front end are input (step DG302). As a result, the above coordinates are stored in a table in the memory (step DG303), and then a line segment connecting the above two points is displayed (step DG304).

By repeating this operation, as shown in FIG. 24(a), line segments 1 and El indicating the position of the front edge of the paper are sequentially drawn on the screen (steps DG305 and DG301).
゜DG302. DG303. DG304).

Once the drawing power of the front end has been adjusted, the shaping command is activated (step DG306), and the points on the front end are rearranged in order of magnitude of the X coordinate (step DG307). Then, display them in the rearranged order and connect each point with a line segment (step DG3
08). This makes the discontinuous part of line segment LEI the 24th
The line segment representing the front end is shaped as shown in [Figure 2] and becomes a continuous line segment. In this way, by using the shaping command in this embodiment, it is not necessary to form a complete continuous line segment from the beginning when forming a line segment.

That is, since it is sufficient to form line segments every other line, the line segment creation work is simplified.

Next, a front end line segment corresponding to the second sheet of paper is formed.

Therefore, here, the offset copy command is activated (step DG309) and the offset amount is input (step DG310). As a result, the offset amount is subtracted from the coordinates of each point at the front end, and the coordinates of each point at the front end of the copy destination are obtained (step DG311).

In other words, there is no need to input the coordinates of each point on the front edge for each sheet, and by copying the data of the first sheet,
It is possible to easily create a diaphragm corresponding to the th sheet of paper. In addition, according to the user's specifications,
You can also add instead of subtracting. The coordinate data corresponding to this second sheet of paper is sequentially stored in the vertical direction in the leading edge information table LIEIT and the changing position table CPT arranged in the second column of the diadem table DT shown in FIG. The same applies to the coordinate data corresponding to the third and subsequent sheets.

Then, by connecting the coordinates of each of these points, as shown in FIG. 24(C), a line molecule, EI, indicating the position of the front edge of the paper is copied, and a line segment LIE2 is generated and displayed (step [1
G312). Repeat this process as many times as necessary (steps DG313. DG309. DG310. DG3)
11. DG312), a predetermined number of line segments representing the position of the leading edge of the paper are generated.

This concludes the explanation of the example usage of the command for forming a line segment indicating the position of the leading edge of the paper.

With the work up to this point, the front edge creation process (steps octon and s in FIG. 20) is completed, so as mentioned earlier, enter the paper size (step DG104) and draw the line indicating the position of the rear edge. Display the minutes (step 0G108)
.

Next, the input signal name of the input signal line required to obtain timing data is input, and the position of the input signal on the paper path, that is, the Y-axis coordinate is input (step DG109). As a result, data on the input signal name and length (position on the paper bus) are stored in the input signal name table l5NT in FIG. Figure (e)
As shown in , the input signal line SL is displayed at the specified position along with its name. This operation is repeated a necessary number of times to input all input signal lines SL. In the example shown, fdo-
snr, reg-snr, fusin-snr,
Input signal lines SL named fusext-snr and exit-snr are drawn.

Each piece of data obtained by the above operations is stored in a virtual array shown in FIG. That is, the front end information section L
The coordinate data of the #J end is in EI, and the rear end information root T[! I
The rear end coordinate data is stored in the input signal name table l5NT, and the input signal name and position data on the paper path are stored in the input signal name table l5NT.

In addition, in the figure, the vertical array shows the data representing the front edge and rear edge corresponding to one sheet of paper, and the horizontal array shows the data of the front edge and rear edge corresponding to each sheet. .

The data created in this way is finally stored in the disk device 6 as described above.

(11) Creating an input chart This is to create a chart that shows the on/off status of input signals from various sensors, switches, etc. installed in the copying machine in chronological order. It is automatically generated from the diagram created in step 5204). FIG. 25 shows a flowchart for creating an input chart.

When the diagram creation is completed and the user instructs to create an input chart, the data of the previously generated diagram is read out (steps IcGI-1cG).
3). Changes in sensor input are then calculated and converted into an input chart (step 1cG4), which is displayed on the screen. For example, if the diagram is as shown in FIG. 26, in the input chart, the line segment LEI at the front edge of the paper reaches the position of the sensor fdo-snr, and then the rear edge of the paper is The output of the sensor fdo-snr reaches the cover-by level during the period until the line molecule EI of the sensor fdo-snr reaches the sensor fdo-snr. The same applies to the next sheet of paper and other sensors.

The above conversion procedure will be generalized and explained.

That is, among the coordinate data of each change point stored in the change point table CPT in FIG. 17, the coordinate data between two adjacent points (XI, yl), (X2. y2)
Based on this, the formula % formula that represents the straight line between each change point is calculated, and this straight line represents the sensor position using the formula y = c. However, C: The X coordinate when crossing the Y coordinate of the sensor position is the input chart This will be a turning point. That is, ax+b=c −b X= − , and this X becomes the X coordinate of the change point.

These calculations are performed by the CPU 1.

In this way, through this input chart creation process,
Signals generated from each sensor when paper passes can be created virtually without using an actual machine.

Input charts created in this way can be edited, and input charts can be created directly without creating a diagram in advance.

You can also edit it.

Chapter 25: When creating a direct input chart
This will be explained with reference to the figures. After entering the process of creating an input chart, if you enter that you have not created a diagram, a list of registered input charts will be displayed (step ICGI).

1cG7) and enter the number of the desired input chart (step ICG8). If there is no registered input chart number specified, after confirming the completion of the input chart creation process, this Zab Session 7 Color? lj, kezuzu (step ICG9. ICG] 3
．． ICGIl+＞.

If the process is not completed, the process returns to the list display of the input chart (steps ICG14 and ICG7). If a registered input chart number is specified,
After input chart data is read (steps ICGIO, ICG12), the process proceeds to input chart editing (step 1cG5). Furthermore, when creating a new input chart, after inputting the input chart name (step IcGII), the process proceeds to input chart editing (step ICG5).

Here, input chart editing will be explained.

When entering the input chart editing process, editing commands are displayed on the input chart creation screen, as shown in Figure 27, in the same way as on the diadulum creation screen, and these commands can be entered using the mouse 4a. By making a selection, a predetermined editing work is performed.

In the figure, an up command section C31 (indicated as Up in the figure).

The down command section C32 (displayed as Down) rewrites the display of the signal line by one water wheel. For example, if the input chart is as shown in FIG. 27, when the up command section C31 is selected, the signal line corresponding to the topmost sensor fdo-snr disappears, and the other three signal lines are Carry up.

This command is effective, for example, when there are many types of signal lines and all the signal lines cannot be displayed on one screen.

In addition, the name change command section C33 (in the figure, Rename
) is used to change the signal name, and the signal name is changed by sequentially selecting the name change command section C33, the target signal line, and inputting a new signal name.

The high-level command section C34 (indicated as tl i g h in the figure) is for setting a specified range to a high level. After selecting the selection command tsv C36, the target signal line, and the high-level command section C34 in sequence, , specifying two points,
It sets the specified range to a high level.

The low-level command section C35 (indicated as Low in the figure) is
Contrary to the high level command section C34, the specified range is set to a low level.

The copy command section C37 (indicated as Copy in the figure) copies, for example, the signal line in the upper row in FIG. shall be. However, at this time, the signal name is not copied.

Further, a movement command unit C38 (displayed as 5hift in the figure) moves an arbitrary point on a certain signal line. For example, two points PI, P2 of the signal line shown in FIG. 28(C)
If you specify the two points Pi and P2 of the signal line shown in Fig. 12(e), the result will be as shown in Fig. 10(f).

Furthermore, the insert command section C39 (indicated as Ins in the figure) is for adding one signal line to the specified position. If the location where the signal is to be displayed is selected with the mouse 4a, a new signal line C is suppressed between the signal lines A and B as shown in Ch) in the figure.

After completing the editing of the input chart using the above-mentioned editing function, if the end command part C40 is selected, the input chart created in the input chart editing process is converted into a file and registered in the disk device 6, and then Proceed to create a serial chart, which will be described later.

In addition, the data created in the input chart process is −
H input chart table IcT (see FIG. 6) and finally stored in input chart file ICF shown in FIG. 29.

This input chart file [CF is the same figure (a
), broadly speaking, it consists of management information and a plurality of pieces of input chart information. and,
The management information consists of the file creation date, the number of input charts, and a plurality of pieces of input chart management information, as shown in (d) of the same figure. It consists of the input signal name, the signal number corresponding to the hardware, and the number of change points. Moreover, each input chart information is composed of height information and time information, respectively, as shown in [(C)].

(iii > Serial chart creation This is to create or edit a chart that defines the transmission and reception timing of serial communication data given at the time of starting or stopping copying, etc. Regarding this serial chart creation, see the flowchart in Figure 30. Explain with reference to.

When entering the serial chart creation process, a list of registered serial charts is displayed in menu format (step 5CGI), and the desired serial chart number is input (step 5CG2). If a registered serial chart number is not specified, remove it from this subsection after confirming that the serial chart creation process is complete (
Step 5CG3.5CG4゜5CG5). If the process does not end, the process returns to the serial chart list display (step 5CG5.5CGI).

If a registered serial chart number is specified,
After the serial chart data is read (step 5CG2.5CG3.5CG6.5CG7), the process proceeds to serial chart editing (step 5CG9). Also,
To create a new serial chart, enter the serial chart name and proceed to serial chart editing (
Step 5CGG, 5CG8.5CG9).

The serial chart editing will be explained below.

When entering the serial chart editing process, as shown in FIG. 31, a template in which the horizontal axis represents time and a plurality of serial lines SRL drawn at regular intervals along the vertical axis is displayed on the screen. displayed above. Note that FIG. 31 shows a case where an already registered serial chart is called up and edited, and in the case of a new creation, the serial line SRL does not exist.

Here, too, various commands are provided for editing.

A serial insertion command section C51 (displayed as 5erialins in the diagram) that adds a serial line SRL to a specified position is unique to serial chart creation.
, a real name command section C52 (displayed as 5erial name in the figure) for setting serial communication data on the serial line SRL and inputting a communication data name.

For example, 12.0 of the upper serial line 5flL
To display the serial communication data symbol named 1np-strt at the 00 μs position, use the mouse 4a to select the selection command section C55, the target serial line SRL, the serial name command section c52. When you select the desired positions on the serial line SRL, you will be asked to input the communication data name, so press r from the keyboard 4.
Enter 1np-strL J. By repeating such operations, the required number of serial communication data generation times and communication data names are set. In the example shown in the figure, the upper serial line SRL has 1np-st as the communication data name.
rt, exchange, reg, expel are input, and 5t is input to the lower serial line SRL.
art, 5top are input.

In addition, the serial parameter command section C53 (in the figure, 5
erial para ) defines the repetition of serial communication data on the chart. The procedure is to use keyboard command 056. Serial parameter command section C53, move the mouse 4 to the desired Y-axis position
If you select a, the timing position and name of the target communication data will be requested, so enter the time and name.

Repeat this process as many times as necessary.

FIG. 32 schematically shows the state of this setting, and in this example, four pieces of communication data, a, b, C, and d, are set. Then repeat start position iul.

The repetition stop position u2 and the repetition end position U are input. As a result, when actual data is generated, the four pieces of communication data a, b, c, and d existing between the repetition start position 1tul and the repetition stop position fi2ua are repeatedly generated until the repetition end position u, 3. It turns out.

After completing the editing of the serial chart using the above-mentioned editing function, if you select the end command section C54, the edited contents will be converted into a file and the serial chart file SC will be created.
F is stored in the disk device 6, that is, a serial chart is registered (step 5CGIO), and then the process proceeds to timing chart creation, which will be described later.

An example of the structure of this serial chart file SCF is shown in FIG. 33.

The serial chart file SCF, as shown in FIG. 2(a), is broadly composed of management information and a plurality of pieces of serial chart information. As shown in the same figure, the management information is composed of the file creation date and the number of real chart information. In addition, each serial chart information, as shown in the same figure (C),
It consists of a serial data name and coordinate data (11+j interval information and position information).

(iv) Timing chart creation This is to create a chart that defines the on/off and input timing of all input signals input to the module by automatically combining the input chart and the serial chart described above. This timing chart creation will be explained with reference to the flowcharts of FIGS. 34(a) and 34(b).

When entering the timing chart creation process, a list of registered timing charts is displayed in menu format (step TCGI), and the number of the desired timing chart is input (step TCG2). If the registered timing chart number is not specified, after confirming the completion of the timing chart creation process, proceed to step TCG3 to remove the timing chart from this subsection. TeO4, TeO5)
. If the process does not end, the process returns to the timing chart list display (step TCG5. TCGI).

If a registered timing chart number is specified (
Step TCG2. TeO3, TeO6), after the timing chart data is read (step T
CG7), proceed to timing chart editing (step T
CG21). Also, when creating a new timing chart, a list of registered serial charts is displayed in menu format (step TCG6°TeO2).
Therefore, input the desired serial chart number (step TCG9). If a registered serial chart number is specified, the process advances to displaying the input chart list (step TCG13). Also, if there is no specification,
ra and gll that do not require a serial chart are performed (step TCGI1.), and if a serial chart is not required, the process proceeds to display the input chart list (step TCG1).
12. TCGI3), if a serial chart is required, return to serial chart list display (step TCG
12. TeO2).

Display of input chart list (step TCG13
), then enter the number of the desired input chart (step TCG 14). If you specify the number of a registered input chart here, you will be asked to input the timing chart salt, so enter the desired timing chart salt from the keyboard 4 (step TCG15.
TCGI8).

In this way, it is possible to create a timing chart as shown in FIG. 35 in which the input chart and the serial chart are combined.

Also in the timing chart editing step, editing can be performed using the same editing function as the above-described serial chart or input chart editing.

When creating this timing chart, as mentioned above, when editing an existing timing chart, when creating a new timing chart using at least one of an input chart and a serial chart, and when depending on an input chart or a serial chart, There are three methods available for creating a completely new timing chart without

It is also possible to define the on/off timing of the output signal in this chart. For example, it is possible to use the above-mentioned editing function to form an output timing waveform that is at a high level within a specified certain period, and add output salt to this waveform.

Here, in this embodiment, a repeat section can be defined in the timing chart creation process. This means that when a basic repetition pattern is specified by specifying an interval on the time axis, that pattern will be repeated for the number of repetitions given later. This is effective when creating data for multiple driving modes. In other words, when simulating the operation of an actual copying machine, tests may be performed by running a large number of sheets of paper, for example, dozens or more, in succession, but it is extremely difficult to create data for each sheet of paper. It's complicated. Here, in this embodiment, by making it possible to repeatedly generate data of the same pattern, necessary data can be easily created even when running tests are performed on a large number of sheets.

This repetition definition procedure will be explained with reference to FIG. 34(b) and FIG. 36.

When the editing of the timing chart is completed (step TC
G21), it is requested to input whether or not to make a repeat definition, so if rNJ is input, the process directly proceeds to timing chart registration (step TCG22.TeO24).

Enter rYJ to proceed to repetition definition (TeO23)
, specify the start and end points of the iterative process for each person's output signal. Note that here, normally one basic input signal or output signal line is selected, and other input/output signals, etc. are aligned to that timing. Then, only signals that do not match this timing are separately designated as exception signals.

In this repetitive definition process, the input of the signal name, start position, and end position is sequentially requested, so in the example of Fig. 36,
After inputting the basic signal name INPUTI, input the repetition start position iVl and the repetition end position v2. This repetition start position v1 and repetition end position 'fl
The setting of V2 is performed by inputting the xv mark, that is, the time value, from the keyboard 4. This setting allows
When actual data is generated, after the preprocessing is completed, repetition starts from position vI and is repeated every (V2-Vl) time, and when this repetition is completed once, the process moves to postprocessing. Therefore, the fundamental signal (V2-v,)
xn is the time for repeated processing. Note that the value of n is specified in a timing data format conversion session described later.

Next, if another signal, for example 0UTPLITI, has a different repetition pattern from the basic signal INPIITI, input the signal name 011TPtlT1 and then similarly set the repetition start position v3 and repetition end position V. good. In this way, these repeat settings can be set independently for each input/output.

Note that for other signals for which no designation has been made, the same repetition as for the basic signal is performed.

Information for these repetitions is stored as management information in a timing chart file TCP, which will be described later.

When the repetition definition work is completed in this way, the process proceeds to timing chart registration (step TCG24), and the created timing chart is stored in the disk device 6 in a file structure as shown in FIG. 37.

As shown in FIG. 3(a), the timing chart file TCP is, broadly speaking, management information and a plurality of pieces of real information. Input chart management information.

It consists of input chart information, output chart management information, and output chart information.

The management information includes the file creation date and input chart name, as shown in FIG.

It consists of serial chart name, presence or absence of repetition definition, basic signal name, repetition start position, repetition stop position, number of real information, number of input chart information, and number of output chart information.

Among these, the data created in the above-described repetition definition process is stored in the areas of presence/absence of repetition definition, basic signal name, repetition start position, and repetition stop position.

Moreover, each piece of serial information is composed of a serial data name and coordinate data (distance information and time information), as shown in FIG. In addition, each input chart management information is composed of the input data signal name, repetition start position, repetition stop position, and the number of line system information in the input chart information, that is, the number of changing points, as shown in 1ffl (d). has been done. In addition, each input chart information is composed of a plurality of line system information, as shown in FIG.
As shown in f), it is composed of height information and time information. The output chart management information, output chart information, and line system information shown in (h) and (i) of the same figure are shown in (d) of the same figure.
, (e) and (f), the description thereof will be omitted since it is the same as the input chart management information, input chart information, and line system information thereof.

(v) Timing chart synthesis This combines timing charts of a plurality of modules to form one timing chart. The resulting synthesis timing chart is used when debugging multiple modules simultaneously.

When the work in the timing chart creation process is completed, an input request is made as to whether the timing chart is to be combined with another timing chart (see step 5210 in FIG. 13). If you instruct synthesis, a list of registered modules will be displayed in a menu format (step TC3I), as shown in the flowchart of FIG.
). If the number of a registered module is not specified, remove it from this subsection after confirming the end (step TC33°TC34, T (:S5). If it does not end, return to the module list display again (step T
C35, TC3I). In addition, if all the modules to be synthesized have been specified, enter "0" to proceed to input the synthesis timing chart name (step T
CS2. TC33°TC36, TC37).

If the number of a registered module is specified, a list of timing charts created for that module is displayed in menu format (step TC38).
Therefore, input the desired timing chart number (step TC39). If a registered timing chart number is specified, the display returns to the module list (steps TC3IO, TC3I). Furthermore, if there is no designation, m M72 that does not require a timing chart is performed, and if a timing chart is not required, the display returns to the module list (step TC3IO).

TC3I1. TC312, TC5I). If a timing chart is required, specifying the module number returns to displaying the timing chart list for that module (step 1'cs] 2. TC38).

When all modules and timing charts to be synthesized have been specified, input of the name of the synthesized timing chart is requested (step T[:S(i, TC97), so input from the keyboard 4. If the name is not input here) If it is, it is confirmed that synthesis is not necessary, and if synthesis is not necessary, it is extracted from this subsection.Step TC313,
TC314, TC315), if synthesis is required, return to inputting the synthesis timing chart name (step TC315).
,TC3? ).

When the name is input, the process proceeds to the timing chart synthesis step (step TC316), where the data of the plurality of modules specified earlier are synthesized with the time axes changed by 1iii, and the result is the same as the timing chart in FIG. 35. Serial communication data and signal lines for multiple modules are displayed in a standard format.

This synthesized timing chart can also be edited in the same way as individual timing charts (step TC317). Further, the repetition information described earlier can be defined in the same way (steps TC318, TC
319). The composite timing chart created in this way is registered in the disk device 6 as a composite timing chart file (step TC320).

Examples of the structure of this composite timing chart file 5TCF are shown in FIGS. 39(a) to 39(e). Note that this composite timing chart file 5TCF is basically the 37th
It has the same configuration as the timing chart file TCP shown in the figure, and is composed of management information, multiple pieces of serial information, input chart management information, input chart information, output chart management information, and output chart information. .

The management information includes, as shown in FIG. 5(b), the file creation date, presence or absence of repetition definition, basic signal name, repetition start position, and repetition stop position.

It consists of the number of serial information, the number of input chart information, and the number of output chart information.

Further, each piece of serial information is composed of a serial data name, a module name, and coordinate data, as shown in FIG. In addition, each input chart management information is composed of an input data signal name, a module name, a repetition start position, a repetition stop position, and the number of change points in the input chart information, as shown in FIG. There is. In addition, each output chart management information includes an output data signal name and a module name, as shown in FIG.

It consists of a repeat start position, a repeat stop position, and the number of change points in the output chart information. Note that the input chart information and the output chart information have the same structure as the timing chart file TCP, so a description thereof will be omitted.

(vi) Creation of timing cheat This converts the timing chart into a text file, extracting all the changing points on the previously created timing chart and displaying them as a table on the screen of the graphic display 5 as shown in Figure 40. This will be displayed on top and also saved as a file. This timing data creation will be explained with reference to the flowchart of FIG. 41.

When entering the timing data creation process, a list of registered timing data is displayed in menu format (step TDGI), and the number of desired timing data is input (step TOG2). If the number of registered timing data is not specified, after confirming the completion, extract from this sub-section (step TDG3. TD
G4. TDG5). If the process does not end, the display returns to the timing data list again (step TDG5).
．． TDGI).

When creating new timing data, a list of registered timing charts is displayed in a menu format, so input the number of the desired timing chart to obtain the original timing chart (step TDG6.
TDG7. TDG8). If a registered timing chart number is specified, the process proceeds to timing data creation (steps TDG9 and TDGI2).

To create this timing data, read the specified timing chart data, serial communication data,
The information arranged for each human output signal is rearranged in absolute time order and stored in the disk device 6 in the form of a timing data file TDF, which will be described later.

Further, when the registered timing data number is designated in step TDG2, the timing data is read out and stored in the memory in the form of a timing data table to be described later. Next, on the screen of the graphic display 5, as shown in FIG.
A standard template for timing data is displayed, and change data of each signal is displayed in this standard template in absolute time order (steps TDG2 and TDG6).
．． TDGI3).

Also, if there is no specification when inputting the timing chart number, timing data will not be created.
is performed (step TDG9.TDGIO), and if timing data is not created, it is extracted from this sub-sensation, and if timing data creation is required, the display returns to the timing chart list display (step TDGI).
I, TDG7).

The timing data thus created can be edited, and is edited using an editing command to be described later (steps TDG14 and TDGI5).

Also, when editing is completed, the timing data table T
IT is converted into a timing data file T[lF, which will be described later. That is, it is stored in the disk device 6.

An example of the configuration of the timing data table TDT is shown in the fourth example.
Shown in FIGS. 2 to 44.

As shown in FIG. 42, the timing data table TDT is a timing data head table TOI.
IT and this timing data head table TflH
It is composed of a plurality of timing data information tables TOIT and a plurality of repetition tables RT, which are sequentially referenced from T in the direction of the arrow.

The timing data head table TDHT contains the 43rd
As shown in Figure (a), the timing data name.

Areas are provided for creation date, timing chart, number of repetition information registered in this table, address of repetition information table, number of timing data registered in this table, and address of timing data table. There is. Further, each timing data information table TOIT includes a forward direction address, as shown in FIG.

Areas are provided for reverse direction address, timing data number, module name, type and data that indicate the type of transmitted/received serial communication data or input/output signals, and absolute time and relative time that indicate the time of the change point extracted from the timing chart. There is.

The data area shown in FIGS. 43 and 43) is the transmission/reception serial communication data table shown in FIGS. 43(c) and 43(d), or the data area shown in FIG.
The configuration of the input/output signal table is shown in (f).

Then, based on the forward address and the reverse address, the timing data information table TDIT to be referred to next is specified as indicated by the arrow in FIG. 42.

Note that when the data is a human output signal, internal links of timing data of the same signal are established to sequentially identify subsequent data.

The same applies to the repetition table RT shown in FIG. 44.

In this way, a timing data table as shown in FIG. 40 can be created.

In FIG. 40, NO9 indicates a serial line number and is used as a symbol for line nibbit in the editor. Furthermore, MOOtlLB indicates the module name in which each input/output signal exists or the module name of the Yabu system to which serial communication data is input/output. Here, an example of a module of a paper transport device named [HM] is shown. Also, RECEIVB and TRA
NSMIT C indicates serial reception and transmission data, and lNPt1T and 0UTPIIT indicate input/output signal names and their changes. Also, TIM [! indicates the relative time in units of ms from the change state of the previous row until the change in that row occurs.

In the example of FIG. 40, in the initial state, fdo-sn
r.

reg-snr, fusin-snr, fusex
The sensor outputs named t-snr and exit-snr are both off, and after 1187Bms they become "0".
The data of ^J is transmitted, and the output of sensor fda-snr is turned on after 6143m5.

Editing can also be performed in the timing data creation process.

This editing work will be explained below.

For example, if the line return key on the keyboard 4 is pressed while a timing data table as shown in FIG. 40 is displayed, the screen waits for editing input. If you enter the line number of the line to be edited here, the system will wait for parameter input and you can edit that line. When editing timing data, MODULE, RECEIV8.
TRANSMIT, lNPt1T, 0LITP
After inputting any UT from the keyboard 4, the setting values are edited. Also, if you enter "+1 (where l is the line number) J, additional editing is possible after the first line, r-fJ
By entering , you can add and edit before the first line.

The edited timing data is converted into a file in the format shown in FIG. 45 and stored in the disk device 6.

FIG. 45 shows an example of the structure of the timing data file TOP.

As shown in FIG. 2(a), the timing data file TOF is broadly composed of management information, a plurality of pieces of repetition information, and a plurality of pieces of timing data information.

The management information is composed of the file creation date, the timing chart name, the number of repetition information, and the number of timing data information, as shown in (B) of the same figure, and each repetition information is As shown in the figure, it consists of a signal name, a repetition start position, and a repetition stop position. In addition, each timing data information is a module number,
It consists of the module name, data type, data itself, and the absolute time and relative time.

In this way, the timing data created by the five subsections of diagram creation, input chart creation, serial chart creation, timing chart creation, and timing chart synthesis described above is stored in the data file as test timing data.

(vi) Timing data format conversion This converts timing data into a data format for the emulation system 7 (see FIG. 4). Regarding this timing data format conversion, the 46th
This will be explained with reference to the flowchart shown in the figure.

When entering the timing data format conversion process, a list of registered timing data is displayed together with the numbers, so the number of the desired timing data is input (steps TOFI, TOI'2). In addition,? When specifying a J7fi file, input timing data numbers consecutively. If the number of a registered timing chart is not specified, extract from this sub-section after 1iffl iff of the end (step TDF3.
TDF4. TDF5). If it does not finish, display the timing data list again (step TDF).
5. TOFI).

If a registered timing data number is specified,
It is determined whether format conversion of all files has been completed (step TDI'6), and the steps described below are repeated until format conversion of all files has been completed.

If the selected file does not have repeat information set, you will be asked to enter the output file name.
Enter a new output file name (step TDF7.
TDF9). As a result, format conversion is executed, and the timing data becomes a data statement in the ASCII file format shown below.

DATA 01. "02"', 03. D
4. "D5-"06"" Here, Dl indicates a time represented by a maximum of four digits, and is a clock-converted value of the relative time from the previous signal change. D2 is a one-character signal type code, ■ is an input signal, 0 is an output signal, C
indicates the transmitted/received data, and * indicates the end code. D3 is a two-digit number indicating the module number, and D4 is a maximum of three digits indicating the input signal number. D5 is a one-character status type code, H is a high level signal, L is a low level signal, S is transmission data, and R is reception data. The last 06 indicates serial communication data and has a maximum of 42 characters.

Note that if the selected file has repeat information set, the number of repeats will be requested first, so
After entering the required number, proceed to step TOFB) to proceed with format conversion. Details of this format conversion will be described later.

When the format conversion of the specified timing data is completed, return to the step of checking the completion of all file conversion,
The user checks whether the file requested for conversion is present in the file (step TDl"6), and repeats the format conversion operation for each timing data specified by the developer. Then, all timing data files TD are
When the conversion of F is completed, the display returns to the initial timing data list (step TDF6. TDFI).

Here, the correspondence with actual data will be specifically explained using the timing chart shown in FIG. 35 as an example. Here, it is assumed that the clock is set to 1000 μs, the module name of the paper transport mechanism is set to CHM, and the module number is set to [4]. Also, in the serial communication data settings, 1np-strt and exchg, respectively.

For the transmission data named e×ρel, reg, r45j, r44A[16090012BJ,
r2DO8A48B655C221211J, r4
Assume that data 4A22[]CD0OOOOIJ is defined. Also, in the input signal name setting, for example, for input signal numbers 1.2 and 4.5, fdo
-snr.

reg-snr, fusext-snr, exit
Assume that the input signal name -snr is set.

These data are stored in the timing data file TDF shown in FIG. 45, and format conversion is performed based on these data. The procedure for this format conversion will be explained.

First, the timing data read from the timing data file TDF (see Fig. 45) is developed into the timing data table TDT (see Figs. 42 to 44), and the timing data information and repetition information of this table TDT are arranged in chronological order. Sort by. Then, relative time, signal type code, module number, input signal number, state type code, serial communication data, etc. are detected in the order of event occurrence and converted into corresponding ASCII codes.

An example of a data sentence obtained by converting the format of data corresponding to the timing chart of FIG. 35 is shown below.

The data statement in the row indicates that in the initial state, the level of the input signal fdo-snr indicated by number 1 is low level, and these signals are related to module number 1, that is, the paper transport module. There is.

Similarly, the data sentences in the second to fifth lines have their respective signals reg-snr.

fusin-snr, fusext-snr, ex
The initial state of it-snr is set.

Next, the data statement on the 6th line indicates that a transmission/reception signal, ie, reception data 1np-strt, is input 1195 clocks after the initial state, and that the content thereof is "45".

Next, the data statement on the 7th line is the previous change point, that is,
This shows that fdo-snr becomes high level 600 clocks after 1np-strt is input.

Thereafter, the state of the timing chart shown in FIG. 35, ie, the data of the timing chart file TCP shown in FIG. 45, is similarly converted into a data sentence.

In this way, by converting and creating the format of timing data in accordance with various take sending systems, the timing data can be made versatile and can be processed by other personal computers for software debugging.

〔Effect of the invention〕

As described above, according to the present invention, changes in signals generated in each paper sensing component are calculated based on the paper shape, t13 data, and component position data input from data input means such as a keyboard and mouse. I'm looking for.

Then, an input chart is generated from data showing this change. This automates the generation of input charts and extremely shortens the time required to create input charts. Furthermore, since no human intervention is required, errors are also eliminated.

Furthermore, if the created data is stored in a file means such as a disk device, it becomes possible to easily create new data by reading and editing the data, which also improves the efficiency of data creation. .
