Abstract

PURPOSE:To simplify an operating and manufacturing device of a copying machine, etc., and also to improve the efficiency of use by obstructing a key input to a displayed information, unless a display information is cleared after a specified interval of time has elapsed. CONSTITUTION:A decision of existence of a key input of an operating device of a copying machine, etc., constituted of a general key part 100, a soft key part 200, a preset key part 300, etc., and a display state of a liquid crystal display device 202 of the key part 200 are checked by a CPU. When the key input exists, and the key input is not a clear key input of a ten key 108 but a display of the device 202 is an operator guidance or an error message, the reception of its key input is obstructed. When these displays are continued for 5sec, they are cleared in the same way as the case when the clear key is inputted, a soft key label and a data are displayed, and as for this display, the input key is received, and the corresponding display is executed. In this way, the operating device of the copying machine, etc. is simplified since it is unnecessary to make a display correspond to a key to one to one, and the efficiency of use is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an operating device for an image information processing apparatus such as a copying machine, a printer, or a facsimile.

2. Description of the Related Art Conventionally, image information processing apparatuses, such as copying machines, simply copy original documents to faithfully reproduce them. Furthermore, even recent multi-functional copying machines have limited functions such as reducing or enlarging a document at a fixed magnification, automatic document feeding function, automatic collation function, etc. These operations are performed by mechanical control, and due to physical limitations, it can be said that the range of multifunctional copying machines has reached its limit. Therefore, even though it is a copying machine operating device,
All that was done was to light up an LED corresponding to each key or switch, or to display the setting status of a function that corresponded one-to-one to the key, depending on the setting position of each key or switch. However, recently, various image manipulation functions using photoelectric conversion elements,
Image information processing devices having an image transfer function, an image quality processing function, etc. have been proposed. Therefore, if an operating section with a one-to-one correspondence between keys and functions is used, the device becomes larger and the operation becomes complicated.

Purpose The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide a display section, function keys, etc. on the operation section,
It is an object of the present invention to provide an operating device for an image information processing device such as a copying machine that has improved usage efficiency and is simplified.

Embodiment FIG. 1-1 shows the appearance of a copying machine and its operating device which are one embodiment of the present invention. This device basically consists of two units. They are reader A and printer B. This reader and printer are separated mechanically and functionally.
It is designed to be used on its own.

Connections are made using cables, etc. Also, reader A has operating device A.
-1 is provided.

FIGS. 1-2 are structural cross-sectional views of a copying machine and its operating device according to an embodiment of the present invention. The document is placed face down on the document table glass 903, and its placement reference is on the back left side when viewed from the front. The original is pressed onto the original glass by the original cover 904.

The original is illuminated by a fluorescent lamp 902, and the reflected light passes through mirrors 905 and 907 and a lens 906 to the CC
An optical path is formed to condense light onto the surface of D 901. The mirror 907 and the mirror 905 are arranged to move at a relative speed of 2:1. This optical unit is moved from left to right at a constant speed history by a DC servo motor without applying PLL. The moving speed is 180 mm/sec on the outward path while irradiating the document, and 468 w/sec on the return path. The resolution in the sub-scanning direction is 16 tines7. The size of documents that can be processed is from A5 to A3, and the document placement direction is As and Bs.
, A4 is placed vertically, B4. A3 is placed horizontally. There are three return positions for the optical unit depending on the document size. The first point is A5. B5. The second point is the same for B4 (at 364am), and the third point is the same for A3 (at 431.8wm) for both A4 and 220- from the document reference position.

Next, regarding the main scanning direction, during main scanning, the maximum width of A4 paper is 297 mm depending on the orientation in which the document is placed.

In order to resolve this at 16 PeL/lan, the number of COD bits is 4752 (=297X16
) bit is required, so this device uses two 2628-bit CCD array sensors, and the K
did. Therefore, 16tines/T! rr! , 180w
Based on the condition of n/sec, the master is given Figures 1-1 and 1-2.
In the figure, the outline of the printer placed under the reader will be explained in (1). The image signal processed by the reader section and made into bit serial is input to the laser scanning optical system unit 925 of the printer. This unit consists of a semiconductor laser, a collimator lens, a rotating polygon mirror, an Fθ lens, and a tilt correction optical system. The image signal from the reader is applied to a semiconductor laser and undergoes electrical-to-optical conversion, and the diverging laser light is converted into parallel light by a collimator lens, and is irradiated onto a polyhedral mirror that rotates at high speed, thereby scanning the laser light onto a photoreceptor 908. . The rotation speed of this polyhedral mirror is 600 rpm. During the scan, it is approximately 400 mm, and the effective image is 297 mm in A4 horizontal size.
It is m. Therefore, the signal frequency applied to the semiconductor laser at this time is approximately 20 MHz (NR,z). Laser light from this unit is incident on photoreceptor 908 via mirror 924.

For example, the photoreceptor 908 is composed of three layers: a conductive layer, a photosensitive layer, and an insulating layer. Therefore, process components are arranged thereto which make it possible to form an image. 909 is a front static eliminator, 910 is a front static eliminator, 911 is a primary charger,
912 is a secondary charger, 913 is a front exposure lamp, 914
915 is a developing device, 915 is a paper feed cassette), 916 is a paper feed roller, 917 is a paper feed guide, 918 is a registration roller, 9
19 is a transfer charger, 920 is a slow roller, 921 is a conveyance guide, 922 is a fixing device, and 923 is a tray. The speed of the photoreceptor 908 and the conveyance system is the same as the forward path of the reader < 18
(1 m/sec. Therefore, the speed when copying with a combination of reader and printer is 30 A4 sheets/min. Also, in order to separate the copy paper that is in close contact with the printer IL photosensitive drum, A separation belt is used, but because of this, the image on that belt is missing.If a signal is also placed on that part, it will be developed, and the separation belt will be stained by the toner, which will cause problems with subsequent paper. This may result in dirt being added to the separator belt 1 on the leader side in advance.
At 8tMn per minute, the video electrical signal for printing is cut off. Also, if toner adheres to the leading edge of the copy paper, it will wrap around the fixing roller when it is fixed, causing a jam, so the reader side must also cut off the electrical signal to prevent toner from adhering to the two leading edges of the paper. are doing.

In addition, in the device of this example, the image information is an electrical signal;
Furthermore, since the reader and printer are separated and have independent functions, it is possible to transfer image information between them. When communicating, this device can only be used when a reader/printer is included.
In the case of only a reader, a communication module is attached to the reader side, and in the case of only a printer, a communication module is attached to the printer side, and local communication within the premises is made possible by connecting these units in a loop. Communication outside the premises is made possible by placing a gateway 4 (an interface between the public line and the local network) on the loop.

Furthermore, an e-mail system or the like can be configured between the head office building and the branch office building, which are connected to the network and the copying device unit.

Next, the functions of the copying machine and its operating device according to this embodiment will be explained. In addition to the basic copying function, this device also has a variable magnification function that allows you to enlarge or reduce the size of the document, an editing function that allows you to extract or delete any part of the document, and also automatically detects the size and position of the document. It has various functions such as automatic scaling and editing. These functions for manipulating images of documents are collectively referred to as "image manipulation functions." In addition to making copies of original images scanned by a connected printer, the CCU (Communication Coordinator)
ntrolLlnit=communication control unit),
Document images can be sent to other printers. or,
You can also receive original images sent from other readers to your local printer. Such functions are called "image transfer functions."Furthermore, the above-mentioned selected functions can be arbitrarily registered in the six preset keys.The registered contents can be specified arbitrarily by the user. The contents are retained even when the power is turned off.This kind of function is called the "preset function." Furthermore, there is an automatic exposure function that removes the background of the original, and a halftone processing function that outputs images with gradations such as photographs with good reproduction.

These are collectively referred to as "image quality processing functions." To summarize, there are five image manipulation functions:

Variable magnification functions include equal magnification (100% magnification), fixed magnification (specified size), stepless variable magnification (specified magnification 50-200%),
There is Y magnification (independent magnification in the main and sub-scanning directions).

The image reversal function includes original image, negative/positive reversal image.

Editing functions include no editing, white masking, and black masking. However, the latter two automatically switch to auto XY magnification, and other magnification functions cannot be specified. Additionally, there are white frame trimming, black frame trimming, and automatic document position detection. However, here, the magnification, image reversal, movement, and special magnification functions are linked.

The movement functions include no movement, movement destination designation, origin movement rA (cornering), and centering.

Special magnification function: No special magnification specified, magnification O), X
There is a Y variable magnification auto. However, the latter two cannot specify other scaling functions. The movement function and special variable magnification function are effective only when the editing functions such as white/black frame trimming and automatic document position detection are specified.

Image transfer functions include local copy (normal copy), transmission (sending original images to other printers via the CCU), and receiving (receiving original images from other readers via the CCU). .

Also, the preset functions include registration (memorizing in the preset key) and reading (reading out the stored contents of the preset key). Some preset keys also have a reset function to return to standard mode.

Further, the image quality processing functions include automatic exposure (AE) and halftone processing.

(HA document position automatic detection). The 5th digit in area b in FIG. 7-1 is an auto display area, and only when automatic scaling is set in the edit mode, "auto" is displayed as shown in FIG. 7-3. The 10th digit in area C is a magnification display area where one of the characters shown in FIG. 7-4 is displayed. Note that the portion bd in FIG. 7-4 shows an example of the magnification input by the operator.

In the display state of FIG. 7-1, if SK6 corresponding to "-ETC" is pressed, the display state becomes as shown in FIG. 8-1.

The 5 digits of area d in FIG. 8-1 are negative/positive inversion ON/OFF display areas, and either one of FIG. 8-2 is always displayed. The 11th digit of area e is a transmission mode name display area, and one of the characters shown in FIG. 8-3 is always displayed.

Next, we will explain the procedure for setting the variable magnification function (see the flowchart for setting variable magnification mode in Figure 9-2). When the corresponding key SK4 is pressed, the display 202 will display the 9th-
It will look like Figure 1. Here, the SK corresponding to “CANC”

This is one of the reset keys. If you press the SKI key indicating enlarged copy in Figure 9-1, b in Figure 7-4 will be displayed.
A question mark is displayed next to the type of enlargement for part b. By pressing the ETC key SK6, a desired enlargement is displayed, and when that key is pressed, a question mark and an exclamation mark are displayed, indicating that the setting has been made. Even if you press the SK2 key indicating reduced copy,
Similarly, a question mark is displayed in the bc section of Fig. 7-4, and keys are set. '95%'
Even if you press SK3 corresponding to the display of '100%' and SK4 corresponding to the display of '100%', an exclamation will be displayed on the selected side of the magnification display in part ba of Figure 7-2.'' 9-3 shows the transition state of the display on the display (202 in Figure 2) when the key SK5 corresponding to "Click here" is pressed.
As shown in the figure. If the magnifications in the X direction and Y direction are not equal in the previous time, the setting procedure for arbitrary magnification starts from the display state 9-a, and if they are equal, from the display state 9-b. “CANC” key S
When K6 is pressed, the arbitrary magnification change mode is canceled and the display returns to the stage before that mode is set, that is, display state 9-1 (this is one of the reset keys).In display state 9-c'' When the key SK5 corresponding to "No///" is pressed, the display state changes to display state 9-d.

Figure 2 108 is located at the under par part shown here.
A desired magnification, for example 123%, is set using the numeral keys and the enter key 109. And display state 9-
It becomes e. Also, in display state 9-f, No? Press the ``'' key SK5, and the display status becomes 9-e. Then, OK.
"Press 5 on key 8 of 7. Display state 9-g will appear, indicating that the magnification has been set. If you want to change the magnification, press the key corresponding to the part you have set (for example, 9-h) to change the display state. Return to 9-d.You can then specify a new item.

When the key SK4 corresponding to "YES?" is pressed in display state 9-c, the display state changes to display state 9-i in FIG. 9-4. Also, in 9-f, 'YES! ! ! ” When you press the key corresponding to “, the display state 9-
Transition to i.

The box 9-4 figure will be explained below. In the display state 9-4 of FIG. 9-4, since the magnification in the X direction and the Y direction is specified, the under par of the magnification display section in the X direction first blinks.

When a magnification is input using the numeric keypad and enter key, the display state changes to 9-j, and in order to specify the magnification in the Y direction, the under par of the magnification display section in the Y direction blinks. Similarly, when a magnification is input (for example, 78%), the display state changes to display state 9-k. Further, from the display state 9-c in Fig. 9-3, by pressing SK4, the display state 4C changes directly to the display state 9- in Fig. 9-4.

If you wish to change the magnification here, press the corresponding keys such as 9-1 and 9-m (2:1 correspondence in this case) to return to the display state 9-n or 9-j. Also, display status 9-k
When 5 is pressed on the key 8 corresponding to "OK", the display state becomes 9-p, and the designation of the magnification is completed.

At 9-n, press the function key (soft key) 8 to 6 corresponding to 'CANC' to return to the stage before setting the magnification, and the display state will be as shown in Figure 9-1. can be said to be one of the reset keys).

Next, in FIG. 8-1, a description will be given of the case where the transmission mode is entered by manual input of the keys of SK2 (see the flowchart for performing transmission in FIG. 10-1). SK2 in Figure 8-1
By inputting the key, the display state becomes 10-a in FIG. 10-2.

The display state of Jin changes to display state 10-b after a certain period of time has elapsed due to a timer. Here, the destination is specified (FIG. 10-1, IQ-aa). 'S1? ", 1 s 2?",

Transition to 0-d (FIG. 10, 1O-bb).

After that, specify the size as described above.

Next, the editing mode will be explained. In editing mode,
As mentioned above, there are three major steps: trimming, masking,
There is automatic document position detection, etc., but first I will explain trimming. FIG. 11-1 shows a trimming mode setting flow. Note that trimming has the functions of specifying a destination, moving the origin, and centering. First, in step 11-b of FIG. 11-1, it is set whether unnecessary parts of the image area are to be made white or black. The display state at that time is shown in 1l-bb of FIG. 11-2. If SK6 (cancel key) is pressed here, the display returns to the display state 11-, aa in FIG. 11-2. Note that the display state 11-aa changes to the display state 11-aa when the soft key SKI corresponding to 6-change 7' is pressed in FIG. 7-1. In the display state 1l-bb of FIG. 11-2, a flag is set that makes unnecessary parts of the image area white unless SK1 or SK2 is pressed. Also 8 to 3 or 8
If you press 4, a flag is set to make unnecessary parts of the image area black. Then, step 11- in Figure 11-1
At C, input the trimming point using the numeric keypad, clear key, and enter key. The display state in Figure 11-2 is from 1l-CC (for a certain time as a timer) to 11
-dd, under par blinks and waits for input from the numeric keypad. Then, use the numeric keypad to select 1l.
-Set the trimming point as in the display state of ee. If you want to change the value, press the clear reset key 114 in Figure 2 to reset the setting (this can also be considered a reset key), or press the soft key below the value you want to reset and reset the setting. figure. When the key 5l (5) corresponding to OK is pressed in the display state 1l-ee of Fig. 11-2, the display state becomes 1l-ff, and the stage of setting the movement point (step 11-'d of Fig. 11-1) is entered. The display state 1l-ff is changed to the display state 11-g by the timer.
Transition to g. If you press SK1'i, N in step 11-d.

Go to and change only the magnification. Enter step 11-11.

Here, select whether to use XY magnification auto, magnification auto, or specify the magnification.

In the display state 11-gg of FIG. 11-2, SK2.8 is 3.
When any of SK4 is pressed, the step of moving the trimming area (step 1l-=e in Figure 11-1,
11-f.

11-g).

If you want to move the trimming area to a certain position, click “
City? 51 (moving destination designation flag set by pressing the 2 key) corresponding to ", set the moving point in the same way as the trimming point set. After that, step 11-h
Enter the magnification setting stage.

If you proceed to NO in step 11-e in Figure 11-1 and proceed to YES in step 11-f, that is, if you press SK4 in the display state 11-gg in Figure 11-2 (origin movement flag set), Next, the process proceeds to step 11-1 in FIG. 11-1, and a magnification setting stage is entered. In other words, it is equivalent to the variable magnification mode in which the document is placed at the corner of the document table.

In the display state 11-gg in Figure 11-2, "center?" ”
If you press the key SK3 corresponding to
YES in step 11-d in the figure, NO in Stella 7'11-e, No in step 11-f, Y in step 11-g.
ES,! : If the result is a, the centering flag is set and the step of setting the magnification is entered in step 11-h of FIG. 11-1. This is equivalent to placing the original at the center of the original table.

Next, the movement destination designation, origin movement, and centering in the trimming mode described above will be briefly explained with reference to a diagram of a document table and a document.

Figure 12-1 shows a document placed on the document table, with the origin (0,
0) is the upper left corner of the document table. Reference numeral 903 is the document table shown in FIGS. 1-2. 12-a is a manuscript. The setting of the trimming point is the X coordinate of the diagonal point (12-b, 12-c) of an arbitrary rectangular area as shown in Fig.
MAX, 'l'XMIN, Y coordinate 'l'YMAX,
It is set by specifying i'Th4IN (unit: line).

When setting the destination of the trimming area, the first
As shown in Figure 2-3, specify the X, Y coordinates of the trimming area.
Specify where to move the point with the minimum value in each direction (point 12-b in Figure 12-2) (Figure 12-3)
b' point).

Next, the case of moving the origin will be explained. In order to set the coordinates of the minimum point 12-b of the trimming area in Figure 12-2 to (0, 0), the
Subtract the values of the X coordinate and Thereafter, if scaling is specified, enlargement and reduction steps are performed. For example, FIG. 12-5 shows reduction, FIG. 12-6 shows enlargement, and point 12-b'' in FIG. 12-4 remains at the origin.

Next, the case of centering will be explained. FIG. 12-7 shows this procedure for determining a moving point based on input data (coordinates of points 12-a1 and 12-b in FIG. 12-2) by setting trimming points. 12th-
FIG. 8 is a diagram showing a case where the image is centered and the magnification is set to 2x for both MX and MY. In Figure 12-7, P
BX and PSY are the lengths of the copy paper in the X direction and Y direction, respectively.

In step 12-aa '1. 'XMAX-T XM
IN and TYMAX-TYMIN represent effective trimming widths in the X direction and Y direction, respectively. Therefore, multiplying each by the magnification represents the length of the trimming area to be actually copied in the X direction and the Y direction. Therefore, TXM, TY
M is as shown in FIG. 12-8 (in FIG. 12-8, the magnification is 4X=MY=2).

Further, in FIG. 12-8, both the X direction and the Y direction are 0 or positive. Therefore, in step 12-bb, if TXM>0 and TYM>0, the coordinates do not exist on the document table, and a warning is displayed. Also, TXM〉0 and '1''
If YM>0, moving 'J'XMIN to TXM and TYMIN to TYM at point 12-b in FIG. 12-2 results in the result as shown in FIG. 12-8.

Next, masking will be explained in edit mode. 1st

When a masking point is specified, the B4 size is automatically enlarged and copied to the selected paper cassette size. Step 13- in Figure 13-1

Transition to f. If SK6 is pressed here, the display returns to the display state 13-b in FIG. 13-2, and the settings can be made again. Thereafter, settings are made using the numeric keypad, and in step 13-dd of FIG. 13-1, masking points are set in the same manner as the above-mentioned trimming points. An example of the settings is shown in Figure 13-2 Display state 13
- Shown in g. Since this is white masking and automatic magnification, even if you press the soft key SK4 corresponding to '100%', you cannot change the magnification setting.

Next DPAD ]) OCUMENT PO8ITION
AUTO])ETECTION Automatic document position detection will be explained.

FIG. 14-1 shows a state in which a document is placed on the document table of reader A shown in FIGS. 1-1 and 1-2. Basically, the placement position is fixed based on the origin, but it can also be placed diagonally as shown in the figure.

'E'l' in display state 1l-aa in Figure 11-2
When the key SK5 corresponding to "C" is pressed, the display state changes to the 14th
-It will look like Figure 5. Here, if you press the SKI corresponding to "DPAD?", the mode becomes DPAD mode. DPAD is a mode in which a required portion of the document can be copied by placing the original at an arbitrary position on the document table without having to align it with the standard position of the document table.

In Figure 14-1, in this case, the reference coordinate S on the document table is
From P, the main scanning direction is X1, the sub-scanning direction is Y, and the coordinates of the four points are (X, , Y, ), -(X, , Y,
), (X,.

Y, ), (X, , Y, ) are detected by pre-scanning the optical system during the pre-rotation operation period of the printer. This allows the size and position of the document to be determined. This makes it possible to determine the scanner scan stroke during multi-copying and to select a desired cassette. The document cover 904 (FIGS. 1-2) is mirror-finished so that image data outside the area where the document is placed is always black data. The pre-scanning includes main scanning and sub-scanning to cover the entire glass surface, followed by scanning for printing. This sub-scanning speed is faster than that during printing.

The circuit diagram in FIG. 14-2 shows the logic for detecting the coordinates. The image data VIDEO that has been binarized by the previous scan is input to the shift register 501 in 8-bit units.

When the 8-bit input is completed, the gate circuit 502
Check if all bit data is a white image, and
If it is es, 1 is output to the signal line. After starting scanning the original, the F/F 504 is set when the first 8-bit white appears. This F/F is reset in advance by VSYNC (image leading edge signal). After that, it is left set until the next VSYNC comes. When the 17F 504 is set, the value of the main scanning counter 551 at that time is loaded into the latch F/F 505. This becomes the X coordinate value. Also, the value of the sub-scanning counter 552 is loaded into the latte 506 at that time. This becomes the Y coordinate value. Therefore P,
(X, .

Y, ) can be found.

Also, each time 1 is output to the signal 503, the value from the main scanning is loaded into the latch 507. This value is immediately stored in clutch 508 (until the next 8 bits enter shift register 501). When the value from the main scan when the first 8-bit white appears is loaded into latch 508, latch 51
The comparator 509 compares the data with the data of o (which is set to 0'' at the time of VSYNC). If the data of the latch 508 is larger, the data of the latch 508, that is, the data of the launch 507 is loaded into the latch 510. Also, at this time, the value of the sub-scanning counter is loaded into the latch 511. This operation is processed until the next 8 bits enter the shift register 501.
If the data of the 8-latch 510 is applied to the entire image area, the maximum value of the original area in the X direction remains in the latch 510.
The coordinates in the Y direction at this time remain in the latch 511. This is the p, (x, , y, ) coordinate.

F/F 512 is an F/F that is set when 8-bit white appears for the first time in each main scanning line and outputs horizontal synchronization signal H8.
It is reset by YNC and the first 8 bits are set to white and held until the next H8YNC. When the F/F 512 is set, the value of the main scanning counter is set in the latch 513, and is loaded into the latch 514 until the next (18YNC). Then, the latch 515 and the comparator 516 compare the magnitude. The maximum value in the X direction is preset in the latch 515 at the time VSYNC occurs. If latch 51
If the data in latch 514 is thicker than the data in latch 514, signal 517 becomes active and the data in latch 514, that is, latch 513, is loaded into latch 515.

This operation is performed between H8YNC and H8YNC. When the above comparison operation is performed for the entire image area, the latch 51
5 remains the minimum value of the document coordinates in the X direction. This is X. Also, when the signal line 517 outputs,
The value from the sub-scan is loaded into latch 518. This is Y.

become.

Latches 519 and 520 are loaded with the main scanning counter value and sub-scanning counter value at that time every time 8-bit white appears in the entire image area. Therefore, when the document pre-scanning is completed, the count value at the time when 8-bit white appears last remains on the counter. This is (x, ,
y, ).

The above 8 latches (506, 511, 520, 518
, 505° 510, 515.519) are connected to the pass line BU8 of the CPU in FIG.
The CPU will read this data at the end of the previous scan. Of these data, Xs, Xs
, L, and Ya are determined as document areas, and trimming processing is performed when scanning the document for printing.

That is, the coordinate components of the original are X, , X, , Y, ,
By Y, the coordinates of the dotted rectangle surrounding the document positions P, to P4 can be recognized, and it can therefore be seen that at least a sheet of a size corresponding to the dotted line is required.

Hereinafter, an embodiment will be described in which the document is automatically detected, an automatic magnification command is input, and this portion is magnified and printed to a size that fits the sheet of the gusset.

As shown in FIG. 14-3, the ratios mx and my of the document sizes Ax and Ay in the X and Y directions to the sizes Px and Py of the cassette sheet in the X and Y directions are determined. Then, the smaller ratio is set as the common magnification for X and Y.
Set it to AM and perform the magnification change procedure described above. Therefore, a copy with automatic scaling based on one direction of the sheet can be obtained.

Further, in FIG. 14-4, the ratio of each of the X and Y directions of the document to the X and Y directions of the sheet is determined, and the magnification in the X direction and the magnification in the Y direction are each set independently. Therefore, the original image can be copied to fill the entire sheet. These two types of automatic zooming are similar to the automatic zooming that is performed by specifying the trimming coordinates described above.

Further, the size specification in the transmission mode also refers to the specification of the size of the cassette sheet.

Next, the black frame erasing mode will be explained. For example, in FIG. 12-1, this print is reproduced with the outer side of the document set as white. In Figure 14-5, if you press the key SK2 or SK3 corresponding to "Kuroiku Poppy?"
The display state becomes as shown in 15-a in Figure 2-1, and becomes a black poppy sword. The process will be explained below with reference to the flowchart shown in FIG. 15-2. The manuscript size is standard! l) No. 15-1
In the display state 15-a of the figure, if you press the soft key SK4 corresponding to "YES?" (Step 1 in Figure 15-2)
5-aa), the display state transitions to display state 15-b,
8 of the B'l'C keys until the desired document size is displayed.
Press 5. In that case, the display state is 15-b, 15-
C, 15-d, 15-b... If the desired document size is A3, display state 15-b
Therefore, in display state 15-b, for example, A3? ”
By pressing 4 on soft key 8 corresponding to the display (
FIG. 15-2 Step 15-bb) Document size data is set in the RAM as A3. Further, by pressing SK4, the display state becomes the display state 15-e of FIG. 15-1 in which the automatic magnification selection is not possible (step 15-cc in FIG. 15-2). Here, when the key SK4 corresponding to ``YES?'' is pressed, the subroutine SUB AT of Figures 14-3 and 14-4 is executed as described in the variable magnification mode.
The magnification is automatically fixed by the 2°5 UBATI method,
The black poppy mode setting ends. Also, step 15
-cc, display status 15-e, No? “ When you press the soft key SK5 corresponding to
. In other words, in display state 15-f, '100t4//
This can be done by pressing 4 on the corresponding soft key 8.

In addition, if the original size is atypical in step 15-aa in Figure 15-2, the display state 15 in Figure 15-1 is determined.
By pressing the soft key SK5 corresponding to "'No?" at -a, the display state changes to 15-g. Therefore, the document size is determined by inputting data using the numeric keys (step 15-ee). Step 15-cc
The following is the same as in the case where the original is a standard size as described above.

In short, Croix and Keshi modes correspond to trimming the entire document. Also, in each display state, 'C
By pressing the soft key SK6 corresponding to ANC,', the display state setting stage can be returned to the previous stage.

Next, the book mode will be explained. In the display state 1l-aa of Fig. 11-2, if you press the function key SK5 corresponding to "J?JTC'lC", the display state changes to Fig. 14-5. When the function key SK4k is pressed, the flow and display of setting the buttons will be explained with reference to Figure 6-1.

When the key 8 is set to 4, the display becomes 16-b and the copy mode is displayed. In other words, only the left half ()・-F L)
, Right half only ()・-F几), Copy hill and right onto separate sheets ()・-FLR), Copy left and right on one sheet (Full) are displayed. When you turn on one of them, the display is 16
-It becomes C. Depending on the key turned on (16-aa~16
-dd) Copy mode flag is set in RAM. This is for inputting coordinate data using the numeric keypad, and is for updating the abstract and sprint cycle. 16-C asks whether the size of the book is a standard size (1
6-ff), if Yes, the display becomes 16-d. In that case, 86 to A4 will be displayed as the size, B7 to B5 will be displayed by ETC, and then B7 to B5 will be displayed by ETC! l) MIN
, LTR power; displayed. For example, when A4 (16-g
g) A4 data is set, and the display becomes 16-j asking whether the magnification is auto or not (16-hh). If the desired size is not available or the size is non-standard, the display changes from 16-C to 16-g. That is, first, a length input in the X direction is requested (the cursor blinks). If you set, for example, 175# on the numeric keypad and turn on the enter key, it will become 16-h, and if you request a length input in the Y direction, and set, for example, 250, it will become 16-i (16-jj). If you notice a data error at this point, you can correct Y by turning on 1 in 8 and turning on X and SK3. If you set one clause in the X and Y directions to a length longer than the limit, a message saying "Miss book size set" will be displayed when you press the enter key.If not, 16-
16-j when you press '5' on keys 1-8 with OK on 'i'
Proceed to the magnification step. If the magnification is auto in 16-j, it will be displayed whether the magnification is

m.

If the magnification is not auto, 16-0 is displayed and the same magnification is selected. Incidentally, in the case of 16-n, the magnification can be changed as described above. Step 16-hh and subsequent steps are the same as in the above-mentioned black poppy mode. In display 1G-t to n, the copy mode is also displayed to indicate completion of book data setting.

FIG. 16-3 is a diagram showing the relationship between the book and the platen surface, and the book is placed with the binding margin aligned with the BOOK point and along the effective edge of the platen. In Figure 16-2, L indicates the scan stroke of the optical unit when printing the left half, and R indicates the scan stroke of the right half or full print. Before the magnification auto step, the coordinate conversion (according to the copy mode) is performed using the size data. In L mode, TYMiN+-Yl, TYMAx+-(Y2+Y1)
XI/2K conversion, and in R mode TYMiN4-(
Y2+Y1)×1/2. TY, MAX+-Y2, no conversion is performed in full mode, and both L and R conversion data are stored in full mode. Then, at the end of the automatic magnification routine, the centering routine described above is performed, and the final coordinates are determined by centering based on the converted coordinates and the magnification. Further, the inverted position of the optical unit in the case of R is determined from the converted coordinates and set. wife#)
For L, it is (Yl +Y2) 1/2+r, and for Rl full, it is Y2+r.

In half LR, when returning after scanning one cycle for L, the main CPU determines whether or not the LR7 lag is set in the RAM, and if it is set, it continues to read data for R and performs the second cycle scan. Start and print the right half. Both the L and R portions are printed in the center of the sheet.

Furthermore, the DPAD mode mentioned above is almost the same as the book mode.
, DPAD automatically recognizes the position and size of the document and processes it for RA.
In the book, the attachment of the original is fixed and the size is manually set using the soft keys. There is no display of the magnification, and the magnification is not displayed when the magnification is auto-set.

Therefore, the coordinate conversion process during DPAD is performed when the copy key is turned on and the optical unit is scanned forward to read the document coordinates. This is done during the middle of the scan and before the start of the main scan.

In addition, DPAD automatically erases black spots 17 in the book.
(Trimming) processing is performed.In addition, in the masking mentioned above, the mask processing 1 gray transfer processing of the data read from the actual CCD is performed by the CCD rotation processing shown in Fig. 18.
The output is image quality-converted by dither processing, etc., and the image data is transferred from the shift memory according to the 1, scaling data, and movement data stored in the shift memories (1) and (2) for one line in the X direction. is output.

On the other hand, if you set 0F=1 and BB=0, a white mask will be created.'! If 0F=O, the output of 90.91 will be 1°O during each period, so if BB=1, the outside of the trimming will be black, 0FF=O1B

The counter is preset by the aforementioned mask point set data.

The above explains the mode setting procedure in step 7, but below:
I will explain the preset keys that register the set mode. Magnification 1 editing mode, positive/negative, destination and size, copy size.

It is possible to register eight types of original image quality, number of copies, and density. When you press the function key SK5, which is displayed as ``TO LOCK'' as shown in Figure 8-1, the 17-1
The display state shown in the figure will be displayed. ○ The copy mode at the time of pressing will be completely registered by the preset key. It is also possible to combine items registered using preset keys and register a new one. However, if there are modes that conflict with each other, their priorities must be considered. All of this is done by comparing the flags.

Hereinafter, for explanation of registration, a flowchart of the entire apparatus is shown in FIG. 17-2. Here, type 1 indicates the display state shown in FIG. 7-1. Type 2 indicates the display state shown in Figure 8-1. Type 4 indicates the display state shown in FIG. 17-1. Since the editing mode 9 has been described above and is the source of explanation, its explanation will be omitted here (step Sl). “ETC” S
Press the K6 key to move to the Type 2 LCD display. Also, the above-mentioned negative/positive reversal mode setting stage (step S2)
Next is the aforementioned transmission mode (step 83).

Also, type 1. Copying is possible only in the Type 2 display state, and at each stage it is possible to return to the stage before setting that mode by pressing the "CAMC" key. The registration mode is located at step $4. The registration mode will be explained below in Figure 17-3.

A registration flowchart is shown in FIG. 17-3. The registration flowchart will be explained below. PK represents a preset key. In Figure 17-3, when you press SK5 corresponding to "Touroku", the display state changes to registration mode (type 3).
Then (step 17-a), the six indicators 303 corresponding to the preset keys 302 in FIG. 2 blink (step 17-b). In this state, the S corresponding to “CANC”
Pressing K6 interrupts the registration process and the display becomes Type 2 again as shown in Figure 8-1. In other words, the cancel key (one of the reset keys) returns the mode setting to the previous level. On the other hand, in the state of step 17-b, any key PK of the preset key (#; 2, figure 302)
When i (1-1-6) is pressed, the preset key display 302 of PKj (j=1-6.1-j) is turned off in step 17-c. Then, the PKi preset key indicator 302 lights up. Psi 5TATUS on RAM which becomes 1 if registered in step 17-d
The flag R is set to 1 in step 17-e.
MAIfu-MODE on AM (1 shown in Figure 17-4)
(consisting of one type of flag) is the Psi on the RAM.
The flags are stored corresponding to MODE (consisting of 11 types of flags shown in FIG. 17-5). In step 17-f, the MAI on the RAM, which is data for transmission, is
The NSD TBL is stored in the Psi SD TBL on the RAM, and in step 17-g, the MAINllil:DIT TBL on the RAM, which is data for editing, is stored in the RA
Stored in PSf EDIT TBL on M.

Then, a flag Psi -8TATUS on the RAM indicating that the preset mode has been registered in PKi is set to 1.

Because of the presets, the flags are backed up by a battery and will not disappear even if the power is cut off.
It is never cleared to 0 except when writing to AM for the first time.

Flag C0P on RAM as shown in step 17-h
Y-z MODE is set to 2', and the preset key display corresponding to the mode of the PKi selected as the registration destination lights up, while the other preset key displays turn off.

The liquid crystal display becomes the type 2 liquid crystal display state shown in FIG. 8-1, and the registration process ends.

Next, a procedure for calling up a registered mode using the 1 preset key will be explained with reference to FIGS. 17-6 and 17-7.

When you turn on the power or press the standard mode return key (Figure 2
01), the mode is standard mode (same size reset), and the standard mode is stored in the main mode area and basic mode area on the RAM (see Figure 17-7). Comparison of the priorities of the preset modes is performed between the main mode and the preset key mode. The mode memory of PS i (1=1 to 6) in FIG. 17-6 is a preset mode memory on the RAM for registering the mode using the preset key PKi (t=1 to 6).

Now, when the power is turned on and the display state is the standard mode, it is assumed that modes are registered only in the mode memories of PS1, PS2, and PS3. For example, Sunzu Psi
Assuming that "trimming, magnification, 100%" is registered in , when you press the PK1 key, YES will be displayed at step 17-aa in Figure 17-7, and P will be displayed at step 17-bb.
Sl is the first input, so NO9 and step l
7-cc Since this is the first input for c, the answer is No. In step 17-dd, the answer is NO because it is the main mode. In step 17-ff, since the main mode is the standard mode, the answer is YES. Then, in step 17-hh, calling of the PSL mode [trimming, magnification, 10011] is permitted, and the PSL mode is memorized in the main mode and basic mode areas in Fig. 17-6. Figure step 17-kk)
. Even if an attempt is made to input PS1 again here, the result is YES in step 17-bb of FIG. 17-7, and the input of PS1 is not permitted. Furthermore, even if a preset key whose mode is not registered in the mode memory of the PS4 or the like is pressed, the answer at step 17-aa in FIG. 17 will be No, and manual keying of the PX4 or the like will not be permitted.

Also, suppose that the mode memory of the PS2 stores a variable magnification mode with a magnification of 200. When the PX2 key is pressed, ygs is displayed in step 17-aa of FIG. 17-7.

Step 17-bb is No, step 17-c
c is NO. In step 17-d, the main mode is Y because the PSL editing mode is stored in memory.
It becomes ES. In step 17-ee, the answer is No because it is the mode of PS2 (only the sex rate mode).In step 17-ff, the main mode is the Psl edit mode stored in memory, but the magnification is 1x. YES, PS217) %-do[magnification 200%J is added to the permission and is stored in memory (Step 17-II) 0 Furthermore,
Assume that the mode memory of PS3 stores a variable magnification mode of [variable (150% J). When the PX3 key is pressed, YES is selected in step 17-aa of FIG. 17-7, NO is selected in step 17-bb, NO in step 17-cc,
Step 17-d In d, the main mode is the PSl mode "Trimming, scaling 200%J," and YES because it is the editing mode.In Step 17-ee, the PS3 mode is only 150% scaling, so YES. No. Step 17-f f is NO because the magnification is 200 cm. In step 17-gg, the mode of PS3 is 150 cm, and it is a variable magnification mode, so NO. No, manual key power of this PX3 is not allowed.Therefore, the main mode has two Psi modes with the two key manual powers of PKl and PX2.

PS2 mode composite mode “Trimming, scaling 2
00%J is stored in memory. Also, if you want to change only the magnification here, use the soft keys! 7152% is “152
If you enter j using the numeric keypad, the main mode will be "Trimming, variable magnification 152%." Therefore, if you want to newly register this as a preset key, press the preset key, and if it is a PS4, register the PS4 preset mode.

The basic mode area in Figure 17-6 is for comparison with the main mode area. If there is a difference, the corresponding preset key will blink; if there is no difference, the corresponding preset key will be lit. be.

Further, operations such as copy transmission are performed using main mode data.

FIG. 19 shows an example of a system that implements the image transfer function.

The operator can continue setting the image forming mode without interruption even after 102f starts blinking.

In the lower stage 2 or station 3, by pressing the copy key 111 or the interrupt key 110, the image forming process of the image information from the reader 191A of the station 1 in the own printer 192B or 193B can be canceled. 192B if canceled
Or, when 193B stops the image forming process and presses the cancel key 11, the light 102f in Fig. 2 goes out and the wash key 1 is pressed.
When 10 is pressed, 102f lights up.

When 102f is blinking in station 2 or station 3, that is, when image formation processing of information from stage 1 is being performed, the cancel key 11 is pressed as described above.

Reception ([Ill informs the operator that one or more stations are out of toner or that waste toner should be collected.

From station 1 to station 2. Before starting the transmission to the station 3 or even after the transmission has ended, there is a paper jam 1 in the operation section of the station 1 at the stage H2 or in the mode 3 for transmission to the station 3.
If a situation such as no paper cassette, no toner, discharged toner collection request, serviceman call error, or wait occurs, the corresponding display 102 on the operation panel of station 1 will be displayed.
A to 102g will blink to indicate that one of the stations scheduled as the destination is experiencing such a situation.
Tell the operator.

Station 1 to Station 1. Station 2.
Even if the mode has already been set on the operation panel of station 1 to send to each printer in station 3, or if the sending process is actually being performed, station 2
．． As mentioned above, if a paper jam or the like occurs at station 3, the corresponding display at station 1 will blink to notify the operator.Furthermore, if a paper jam or the like occurs at station 1, station 1 will display the status of its own station. Gives top priority and lights up the corresponding display.0 If transmission is not set at station 1,
The operation section of station 1 displays only the status of its own station.

The station status display, that is, the process of displaying warnings such as errors, will be explained below with reference to FIG. Toner collection 4. Toner supply 5. Uniformity check from control 6. It is assumed that there are a total of seven stand displays, including serviceman call error 7 and weight.

First, it is checked whether any of the transmittable stations, including the own station and other stations, have any errors (step 21-1). If there is no error, all seven display lamps are turned off to complete the process (step 2l-2).
). If there is any error, first check to see if the first error, such as a paper jam sheller, has occurred in any of them (Step 2l-3), (Step 2l-3).
-4). If no paper jam occurs in any printer, the paper feed 9 inspection display is turned off (step 2l-5).

If the paper jam 9 error has occurred at any station, it is checked whether it has occurred at the own station (step 2l-4). If it is not the own station, a blinking paper feed check display is displayed as an error occurring at another station (step 2l-5). (Step 2l-4), if a paper jam error occurs at the current stage, the paper feed check display is turned on even if a paper jam error occurs at another station (step 2l-5). Now that the paper jam check has been completed, the next step is to check the paper out error (i=2) (step 2).
1-7).

In the same way, each of the seven display stands blinks.

After controlling the lighting and turning off, i=7 in step 21-6.
If it does, the process ends.

As described above, it is possible to distinguish between an error occurring at one's own station and an error occurring at another station using a single warning indicator lamp, making it easier for the operator to handle errors even when the operator is using many printers.

In addition, when determining the presence or absence of an error in step 21-3, in addition to selecting all the target stations that can transmit, select a group consisting of any number of stations, or a group consisting of any number of stations in the same room, or It is easily possible to limit the number of error checks to stations on the floor, and the number of error checks may be any number.

The relationship between display contents on the liquid crystal display section and key processing will be described below using FIG. 22.

In mass step 22-1, the availability of key personnel is checked. If there is any key input, the contents displayed on the liquid crystal display at that time are checked in step 22-2. There are two main types of content displayed on the liquid crystal display. One is soft key labels and various data (magnification, coordinates, etc.) for setting or specifying the copy transmission mode, and the other is operator guidance and operational errors and readers that inform the operator of the setting procedure.

There are error messages that tell you what errors have occurred with the printer. In step 22-2, if the displayed content is soft keys, labels, or data, the process goes to YES, and the input key is not necessarily ignored, but is processed accordingly, and the liquid crystal display content also changes to copy and transmit. Continue setting the mode (step 22-4). Meanwhile step 22-3
If the displayed content is an error message or operator guidance, it is checked whether the input key is a numeric clear key for a part of the numeric keypad.

If it is a numerical data clear key, the displayed message and guidance are erased, and the soft key labels and data that should originally be displayed are displayed (step 22-7). In some cases, the clear key used to clear the set number of images, magnification, coordinates, etc. is also used to clear the contents of the liquid crystal display while messages and guidance are being displayed. In step 22-3, if the clear key is not manually powered, the key is not accepted.

If it is determined in step 22-1 that there is no key power, then in step 22-5 the liquid crystal display contents are checked. If the soft key label and data are displayed, proceed to YES and do not process the inquiry.
N for operator guidance or error messages
The process proceeds to O, and it is checked whether the display continues for a certain period of time, for example, 5 seconds (step 22-6). If it is not displayed for 5 seconds, no processing is performed, but if it is displayed for 5 seconds, the message or guidance is cleared and the soft key label and data are displayed, just as if the clear key had been manually operated.

Effects As described in detail, according to the present invention, the status of the station can be easily determined, the display information can be displayed as abbreviations, symbols, messages, etc., and mode data selection, setting, registration, etc. Since it is possible to change, delete, etc., it is possible to provide an operating device for an image information processing device that is extremely simple, compact, and highly efficient even as image information processing devices become more multifunctional.
