2. Description of the Related Art In recent years, an optical filing system has been developed and spread in order to organize a large amount of documents created or collected in an office or the like in a space-efficient manner so that they can be used at any time. However, the conventional optical filing system is generally expensive and requires complicated and sophisticated operations, so that it cannot be easily used by anyone.

Therefore, for example, a digital copying machine constructed by combining an image reading means (scanner) for reading an image of a document and an image forming means such as a laser printer is integrally provided with an optical disk device as a means for storing and managing image information. The provided image forming storage device has been developed.

As disclosed in Japanese Patent Laid-Open No. 1754 or Japanese Patent Laid-Open No. 4-3260, image information of a document is read and its image information (document information) is stored in a storage medium. There has been proposed a method in which abstract information (index information) corresponding to each is created, an image is formed on the paper, and an index (abstract) sheet is output.

In this case, for example, search information such as a row of holes and a bar code is added and output on an index sheet, and the user reads the bar code or the like of the abstract information with a scanner using the index sheet. It is also proposed that the image information of a document (file) designated by the barcode or the like can be automatically searched for, and the image information can be formed on a sheet and output.

[0006]

However, in the conventional image forming storage device as described above, the user can search and output the image information on the storage medium as described above using the index sheet output by the user. It is necessary to perform a special processing operation for adding search information such as a hole row and a bar code to the index sheet when performing the operation for performing the operation, which causes an erroneous operation because the workability becomes complicated,
The work efficiency was extremely poor.

Further, when the index sheet is read again and the processing such as search / output is determined based on the read image information, the processing time becomes long because of the mediation of the image processing technology, and the work efficiency of the user is remarkably increased. It was bad. The present invention has been made in view of the conventional problems as described above, and simplifies the operation of outputting image information of a desired document by a user using an index sheet to improve work efficiency. The purpose is to

To print. To the printer unit 5, a paper feeding / conveying device for feeding a paper to a position for forming an image, a photoconductor drum and an image forming process device for charging, exposing, developing, transferring, fixing, and the like, and ejecting printed paper Including equipment.

The control unit 6 detects various states and notifies them to each unit, distributes necessary processing to each unit, and notifies necessary processing units as processing instructions. Control unit 6
There is state detection means for monitoring the change in the state of each part, and it constantly monitors the state of each part, rewrites necessary status information as necessary, and generates an interrupt event to each part. Communicate changes in state.

In the description of the operation to be described later, it is described that one unit directly operates another unit, or some unit directly receives information from another unit to operate. However, as an implementation form, the control unit 6 is used. By issuing or receiving an operation command to another section via the, the processing is performed in that section. However, the reason for passing through the control unit 6 is to make it possible to easily maintain uniformity and consistency, and is not essential.

The mode setting unit 7 sets the mode of each unit according to the input from the user sent through the operation unit 2 and the state of the digital copying machine 1. (As described above, the operation is performed indirectly through the control unit.)

The document input unit 8 activates the scanner unit 4 in response to a user's command, causes the image of the document to be read, and temporarily stores it as an image image in the memory (image buffer) of the intermediate storage area. Then, the read image of the original is sent to the storage unit 3 or the printer unit 5.

The index sheet output unit 9 reads out index image data from the storage unit 3 in accordance with a command from the user, forms an index sheet image, and prints it out on a sheet through the printer unit 5.

The index sheet use operation unit 10 causes the scanner unit 4 to read the index sheet set on the contact glass of the document input unit 8, and in response to an instruction on the index sheet or an instruction sent through the operation unit 2. Then, the storage unit 3 is operated. Alternatively, the image data is read from the storage unit 3 according to the instruction, and the image is formed on the paper through the printer unit 5.

The digitizer 12 is a coordinate input device, and for example, as shown in an enlarged view in FIG.
a, the sheet ID reading unit 12b, and the input pen 12c
Consists of. The coordinate information input unit 12a has a sheet on which graph paper-like lines indicating coordinate positions are printed on the upper surface thereof, and the index sheet 16 is set thereon as shown in FIG. Point is input pen 12
When pressed by c, the coordinate position is detected and a corresponding signal is output.

The sheet ID reading section 12b is composed of an optical reading sensor such as a CCD area sensor and reads the index sheet 1D image area of the index sheet set on the upper surface. The read front area is collated with the index sheet ID using a character recognition technique, the details of which will be described later.

In this embodiment, the respective units 6 to 10 enclosed by the broken line in FIG. 1 store a main arithmetic unit (CPU), a data memory such as a RAM associated therewith, and a processing program of each processing unit. Program memory such as ROM,
And a general von Neumann type computer system including an auxiliary circuit such as an input / output circuit (I / O). However, it is fully possible to realize with hard-wired logic. Also, it is all right to realize all of these parts with one computer system.

Further, as the memory of the intermediate storage area for processing and storing the image image and the state of the mode, each section may have its own memory, or a common memory may store the respective intermediate storage areas. It may be provided. In the following description, it is assumed that each unit has its own intermediate storage area memory.

<Logical Structure of Storage Medium> Here, the logical structure of a typical magneto-optical disk 42 is used as the storage medium 40 of the storage unit 3 shown in FIG. The magneto-optical disk has a logical structure as shown in FIG. 5 or 6. In these figures, those enclosed in {} are elements that allow repetition, and those enclosed in [] are optional and optional elements. A :: = ab is A
Means a sequence of abs.

Information regarding the volume of the disk is stored in the head area of the magneto-optical disk (hereinafter, also simply referred to as "disk"). In this area, there are a disc (medium) ID given when the disc is initialized, an initialization date and time, a final writing date and time of the disc, and the like. Also, the disk has a directory structure. The configuration is such that one disk can store n directories.

The directory file is composed of a directory name, a time stamp (final writing date and time) to the directory, the number of files included in the directory, and a list of pairs of the file and the access pointer. This directory is set to group any number of files for easy management. The file must belong to some directory. Therefore, the first directory is used as an unnamed directory, and is used as a default directory unless otherwise specified by the user.

A file is a unit in a disk for collectively storing and managing images related to one reading unit. In the logical structure shown in FIG. 5, this file has a file name, the last writing date and time, a comment character string (comment), accompanying information, image information, and index information. As the accompanying information, paper size and orientation, image orientation, document type, ADF usage information, and the like can be considered.

The image information stores the number of images and image image data corresponding to the number. Further, as the image accompanying information, information on both sides and the like, and information such as a special paper size for allowing the change of the paper size in the same file are entered.
The index information contains the number of index images and the number of index image image data.

In the case of the logical structure shown in FIG. 6, instead of holding the index information separately, an index image flag is provided in the image accompanying information to indicate whether or not it is an index image. As for this part, it is only necessary to know which image is the index image after all, and various logical configurations are conceivable.
The processing logic of the actual call of the index image may differ due to the configuration of this portion, but it is not related to the essence of the present invention unless otherwise stated. In the following description, the logical structure shown in FIG. 5 is assumed unless otherwise specified.

<Processing Flow> Next, the processing flow of the part of the digital copying machine by the computer system surrounded by the broken line in FIG. 1 will be described with reference to the flowcharts of FIG.

FIG. 7 shows an outline (main routine) of the overall processing flow. When the main switch 15 shown in FIG. 2 is turned on (turned on) and the power is turned on, the control unit 6 of FIG. 1 is activated, and first, step 1 (in the drawings and the following description, the step is abbreviated as “S”). Then, each unit is initialized, and then in S2, a standby state is entered, and if there are various state changes, the processing associated therewith is performed.

That is, in the standby state of S2, the control unit 6
Each time a state change is detected, the state change or instruction is notified to each section, and each section performs processing according to the instruction. Main switch 15 is turned off (turns off)
Then, the control unit 6 detects this, performs post-processing of each unit in S3, and ends the process.

FIG. 8 shows an outline of the subroutine for the detection of the state change in the standby state and the accompanying processing in the main routine of FIG. In the standby state, the control unit 6 waits for a change in the state of each unit (including a change in the input of an instruction) in S21, and when a state change is detected, the process proceeds to the next S22 and the power is turned off.
It is determined whether it is FF. If it is OFF, this process is ended and the process returns to the main routine of FIG. 7 to perform post-processing of each part and then end all the processes. OF
If it is not F (if it is ON), the process proceeds to the subroutine of S23, and the processing in each unit is performed according to the state change.

The change in the state of each section includes a change in the input due to the user's receipt of an instruction from the operation section 2, a change in the state of each processing section, and an error state detection. If the state change (hereinafter also referred to as “event”) is accompanied by the end of the file, the process of bringing the file into the read end state is performed.

The contents of this processing are shown in FIG. First, S2
In 4 it is judged whether it is an event to make the file end state,
If YES, the file end state is set, and if NO, the process directly proceeds to S26 and thereafter.

The event for setting the file end state is, for example, a mode change from the user such as setting of an automatic paper selection (hereinafter also referred to as “APS”) function and an automatic magnification selection (hereinafter also referred to as “AMS”) function. Instructions, user actions such as setting documents in the automatic document feeder (ADF),
Timer interrupt due to the fact that the state has not changed for a certain period of time from an event (in this case, a timekeeping means is required)
Etc. are possible.

The instructions from the operation unit 2 are roughly classified into "commands for mode setting (including various state changes)", "copy commands", "commands for outputting index sheet", and "commands for using index sheet". 9 and discriminates it in S26 to S29 of FIG. 9, and proceeds to any of S30 to S33 according to the discrimination result, and respectively sets the mode setting unit 7, the document input unit 8, the index sheet output unit 9, or the index. The sheet use operation unit 10 is started, and “mode setting processing (including internal state setting)”, “manuscript input processing”, “index sheet output processing”, or “index sheet use processing” is started according to the type of event. Execute processing. Then, when this process ends, FIG.
Return to S21 (standby state).

<Description of Each Process and Each Mode> Here, in FIG. 9, "mode setting process" in S30, "document input process" in S31, "index sheet output process" in S32, and "step S33" in FIG. The processing using the index sheet "and each mode thereof will be described in detail.

(1) Mode setting process (FIG. 10) The mode setting unit 7 is activated, and the process shown in the flowchart of FIG. 10 is executed to set the mode of each unit. First, it is judged whether or not the mode can be set at present, and if the mode is NO, processing such as error display is performed and the processing is terminated.

If YES (a mode that can be set), then it is determined whether or not the accompanying information is required. If YES, a request display of the accompanying information and input of the accompanying information based on the request are displayed, and then NO is selected. If there is, the process immediately proceeds to the process of setting the mode of each unit according to the set mode (and accompanying information). When the setting is completed, the process ends.

In this mode setting, naturally there may be another mode which is automatically turned off when a certain mode is set. For example, setting the APS function cancels the AMS function. Also, the modes associated with physical operations are handled in the same manner. For example, the control unit 6 detects a physical operation and sends a command corresponding to the physical operation to the mode setting unit 7.

By the way, the operating conditions of each processing system are changed depending on the mode to be set. The mode setting by the user is made by inputting operation conditions and operation modes from the operation unit 2 and switch operation for each hardware. In addition, the operation unit 2 is configured so that a mode associated with a certain operating condition can be input only when the operating condition is set. However, for frequently used ones, a key that can be directly set is provided.

The mode setting state is held in the control section 6, and when a new state is detected, it is changed as necessary. In addition, the information is sent together with the commands to the other parts. However, a common status status area may be provided and the status information may be written in the common status status area, and each unit may refer to the common status status area.

Each unit has a clocking means (timer), and the mode is set by the timer in the following cases. The time when the mode setting by the timer occurs is different in each case. Discontinuation time during processing of mode and various condition settings → Clear mode setting Suspension time after copying → File end processing Suspension time in each setting state → Clear mode default

(2) Manuscript input process (FIGS. 11 to 16) When a copy command is issued in the standby state (in this embodiment, a copy command is issued when the start key 22 is pressed), the manuscript input The process of is executed. That is, the document input unit 8 and the scanner unit 4 are activated, and the document is read by the scanner unit 4 as an image. The image image is sent to the storage unit 3 and / or the printer unit 5 in accordance with the mode, and storage in the storage medium 40 and various processes associated therewith and / or image formation (printing process) on paper are performed. Let me do it.

Further, the operation unit 2 can also be instructed to change or set the index image of a file in the storage medium 40 of the storage unit 3, or change the file structure. As shown in the flowchart of FIG. 11, this document input process is performed by AD
F It is determined whether or not the document is in use. If YES, the document input process by the ADF (FIG. 12) is executed, and if NO, A
A document input process other than DF (FIG. 16) is executed.

Now, description will be given of a mode which is an operation condition of the process mainly associated with the copy command of the document input section 8 shown in FIG. For example, by pressing the copy mode setting key 33 of the operation unit 2 shown in FIG. 3, the following three types of modes can be switched. Which copy mode is selected is displayed on the display / input combined means 21. 1. Copy only (paper output only) 2. Copy and memory 3. Memory only (no paper output)

The automatic paper selection (APS) function is provided on the operation unit 2.
It is set by pressing the automatic paper selection key 27. If a magnification is set, that magnification is maintained. AM
If S is set, cancel the AMS and increase the magnification to 100.
Set APS as%.

The automatic magnification selection (AMS) function is provided on the operation unit 2.
It is set by pressing the automatic magnification selection key 30 of. If a magnification is set, that magnification is cleared.
If the paper feed tray is selected, hold it as it is.
If no paper feed cassette is selected, the default paper feed cassette is used. If the APS is set, cancel the APS and use AMS as the default for the paper feed tray.
To set.

The magnification can be switched by pressing the scaling key 31. The magnification can be switched between a pre-loaded magnification (paper size mutual magnification, etc.) and a magnification that is arbitrarily set by operating the ten keys 26. When the scaling key 31 is pressed, the AMS function is canceled. When the same magnification key 29 is pressed, the magnification becomes 100%, which is the same as the setting of variable magnification.

Further, by pressing the paper selection key 28, the paper feed cassette can be switched. When the paper selection key 28 is pressed, the APS function is released. When the clear stop key 25 is pressed, the execution of copy, use of index, output of index, etc. is stopped if the execution is in progress. If it is not executed yet, the settings such as the number of sheets and the magnification are canceled, and the default settings are restored.

The ten-key pad 26 is used to set the magnification in the magnification setting mode. In the waiting state,
Specify the number of sheets of paper to output. Further, by pressing the double-sided key 32, it is possible to switch to the double-sided copy mode. In addition, simple editing such as erasing a frame, and designation of shading of a document can be performed.

As described above with reference to FIG. 11, in the process of inputting a document accompanying a copy command, the process is discriminated according to the method of setting the document to be read. That is, the ADF part as a part of the scanner part 4 exists and is in the standby state, and the document is set in the ADF (in the case of the document input by the ADF), and the other cases.

The document input processing by the ADF is the same as the above AD.
It is started when a start command is input from the operation unit 2 while the conditions for the document input by F are met. The fact that the ADF is in the standby state is sent to the control unit 6 when it is detected that the ADF itself is in a state suitable for the standby state (for example, the ADF is set in the main body in a usable state). When the standby state is changed to an unsuitable state, the control unit 6 is notified of the non-standby state.

The setting of the original on the ADF is detected by the insertion of the original into the original feeding section of the ADF or the like, and the signal is sent to the control section 6. When the control unit 6 detects that the start command is issued from the operation unit 2, the control unit 6 notifies the document input unit 8 that the start command has been issued together with the state of the ADF and various modes. The document input unit 8 receives the command and performs the following processing according to each mode.

1. Reading of Originals The original feeding section of the ADF is activated, the originals are fed one by one onto the contact glass, and the scanner unit 4 reads the images of the originals one by one as an image image. Specifically, AD
F processes the original according to whether it is a double-sided original or a single-sided original and sends it to a readable position, and then outputs a read preparation completion command. The control unit 6 that has detected this issues a scan command to the scanner unit 4, and the scanner unit 4 is activated to read the image of the document placed at the readable position, and the intermediate image in the document input unit 8 is read as digital image information. Send to storage (image memory).

When the ADF mechanism is the front side ADF, the original reading is started from the last page of the set original, but the original is turned inside the ADF and the front side (front side) is faced down. Make the image read.
Further, in the case of copying from a double-sided original, first the scanner unit 4 is made to read the image on the back side without turning over the original,
One sheet is processed, then the original is turned over to read the image on the front side, and the same processing is performed. In any case, the reading of the document is sequentially performed from the last page to the first page.

2. Processing of Read Image The following processing is performed in each copy mode. (a) Copy-only mode (copy mode 10) An image is sent to the printer unit, an image is formed on a sheet, and the sheet is ejected. The image forming and the paper output are changed according to the setting of various modes.

For example, when the magnification is set, image formation is performed at that magnification. If the number of sheets is set, the same number of images are formed and the sheets are discharged. Hereinafter, the output processing from the digital image in the intermediate storage unit onto the paper according to the mode is referred to as “copy output processing”. These processes are nothing but the copying process in a so-called digital copying machine.

(B) Storage limited mode (copy mode 01) The image is sent to the storage unit 3 and stored as a part of the file in the storage medium 40. That is, the output process to the storage medium 40 is performed.

(C) Copy and storage mode (copy mode 1
1) A copy mode of the default (simply "default" means a mode or state set when initialized), and performs both processes (a) and (b).

The document input process by this ADF is shown in FIG.
ADF is executed according to the flowchart shown in 2.
It consists of pre-processing when using, a main routine when using ADF, and post-processing when using ADF. First, in the pre-processing when using the ADF, it is determined whether or not the output is to the storage medium, and if it is not output to the storage medium, immediately, if it is output to the storage medium, "file initialization processing" is performed. Go to the main routine when using the ADF.

In the main routine, first, the scanner unit 4 reads one original and stores it as a digital image in the intermediate storage unit. When the original is exhausted (when the original is finished), the main routine is ended and the ADF is used. Go to post-processing.

Next, it is checked whether or not the mode is a mode for requesting output to paper, and if it is that mode, "print processing" is performed. Finally, it is checked whether or not the mode is a mode in which output to the storage medium is requested, and if it is that mode, "image image storage processing" to the storage medium is performed. Either of the “print processing” and the “image image storage processing” may be performed first.

The processing of the main routine is repeated until there are no documents set in the ADF, and when there are no documents, the post-processing when using the ADF is performed. There, it is checked whether it is a mode that requests output to a storage medium, and if it is that mode, "default index image setting processing"
Is performed, and if it is not in that mode, the processing ends.

FIG. 13 shows an outline flow of the "file initialization process" in the above-mentioned pre-process when using the ADF.
In this process, first, it is checked whether or not the current storage status is reading a file. If the file is being read, the process is terminated and the process proceeds to the main routine of FIG. 12, and if the file is not being read. ,
Set the status while reading a file.

Then, a new file area is secured in the storage medium and a file is added to the directory. Allocate the new file as the last file in the unnamed directory, which is the default directory. At this time, the free area in the storage medium is inspected, and if there is no free area above a certain amount left in the medium, medium free area error processing is performed.

Specifically, one file is added to the unnamed directory. The file name at this time is a time stamp (character string of time) in the digital copying machine. And secure the file in the free area,
The new file in the directory should point to this file.

However, before pressing the start key 22, the file name or directory to be stored can be specified from the operation unit 2. In this case, a file area can be secured at the time of designation. When an existing file is designated, the file is added to the file and the initialization process is not performed.

Next, each counter in the secured file is reset and various stored information is initialized. It also stores the copy mode and machine mode. Specifically, it is written at the same time whether the ADF is used, whether it is double-sided or not.

In this embodiment, the file initialization process is started immediately after the start command is issued. However, inside the main routine of FIG. 12, the file read state is judged after reading the first image. Then, the file initialization process may be started when the file is not being read. However, as a matter of course, it is activated only in the mode of requesting output to the storage medium.

FIG. 14 shows a schematic flow of the "image image storage process (output process to storage medium)" in the main routine when the ADF is used. When one document is read, the image image of the document is subjected to a predetermined compression process, and then stored together with its size in the image data area of the file as image image data. Then, the image number counter of the image file is incremented. If necessary, the image accompanying information is added and the process is terminated.

FIG. 15 shows a schematic flow of the "default index image setting process" in the post-process when using the ADF. In this process, the first image image (the image image of the front surface of the first original) is taken out and stored as an index image image. When reading a document fed from the ADF, since the reading is performed from the final document, the first image image is the last registered image image. In other cases, the image registered first is used. After that, the index image number counter is incremented and the process is terminated.

Here, the file end will be described.
When the end of file is recognized, the current status is set to end of file. That is, in the case of reading when using the ADF, the above-mentioned "default index image setting process" is performed. If double-sided printing is designated and the ejected paper is inside the printer unit 5, the paper is also ejected.

Typical end-of-file recognition conditions are listed below. In the case of scanning while using the ADF, the time when all the documents (usually a large number of stacked documents) set in the ADF have been read. However, if the continuation is designated, it is considered continued.

In the case of reading without using the ADF, the time from when the start command is issued until the next original is set exceeds a certain time. If the APS is set, the file is not recognized as the end of the file even if the reading of the original is finished, and the APS setting is canceled by the instruction from the user or the shift to the default mode by the timeout, or File end processing is performed by changing the paper feed sheet in the APS. AM
When S is set, when AMS is canceled, and when the selection of the paper feed tray is changed, the file end processing is performed.

Next, the contents of the document input process other than the ADF in the flow of FIG. 11 will be described with reference to the flow shown in FIG. When a start command is input through the operation unit 2 when any condition of the document input processing by the ADF is missing, the document input processing is performed when the ADF is not used. In this case, a document is set on a document table (contact glass) that is a part of the scanner unit 4, and the size and orientation of the paper is detected by the optical detection means, and the control unit 6 is notified. There are many.

When the start command is recognized by the control unit 6, the start command is sent to the document input unit 8 together with the above-mentioned state information and various mode information, and the processing shown in the flowchart of FIG. 16 is started. First, the document input unit 8 activates the scanner unit 4 to read an image image from the document set on the platen and stores it in the intermediate storage area of the memory.

Then, it is checked whether or not the mode is a mode for requesting output to paper, and if it is that mode, "print processing" is executed. That is, the digital image stored in the intermediate storage area is sent to the printer unit 5, and the printer unit 5 forms an image on a sheet and discharges it. The image forming method, paper selection, or the number of paper sheets may differ depending on the various modes.
This is the same as when using the ADF.

Immediately after the printing process, or if the mode for requesting output to paper is not in effect, it is immediately checked whether or not the mode is for requesting output to the storage medium. If not, the process is terminated. If you are in that mode, first see the current status information. Then, only when the status information is not the read state but the file end state, the "file initialization process" is performed and then the "default index image setting process" is performed at this stage.

After the processing, or immediately in the reading state, the "image image storing processing" is performed to end the processing. However, when the end of the file is recognized, the end-of-file status is set in S24 and S25 in the flow of FIG. To This is performed in the waiting loop of the control unit 6.

Here, selection of an index image and input of additional information will be described. After inputting the original, it is possible to change the belonging directory and file name, additional information, and select an index image. Further, setting of the belonging directory, a part of information such as the file name and additional information can be performed immediately before the input of the document.

For example, when the edit key 36 of the operation unit 2 shown in FIG. 3 is pressed, the display / input dual-purpose device 21 is selected with the file input immediately before selected as the default selection.
Display the file edit screen on. When the "Edit Name" guide is touched on the file edit screen, an input guide appears on the screen, and the file name, directory name, comments in additional information, etc. can be entered and edited in the manner of Romaji-Kana conversion.

When the "index edit" guide is touched on the file edit screen, the index edit screen is displayed. On that screen, the number of index images of the currently selected file is displayed. Also, an index image can be displayed. If you touch "Delete index" while the index image is displayed, that image is removed from the index image and the number of index images is decremented.

Also, images other than the index image can be combined and displayed from the image data stored one after another. Here, if "index setting" is touched, the image is stored as an index image and the number of index images is incremented.

(3) Index sheet output process (FIGS. 17 to 20) When the index sheet output command is input from the operation unit 2 to the control unit 6 while the digital copying machine shown in FIG. The sheet output unit 9 is activated,
A necessary index image image is taken out from the storage unit 3, an index sheet image is formed by appropriately arranging the taken out index image image, printed on a sheet through the printer unit 5, and outputted as an index sheet.

Before issuing the index sheet output command, it is possible to specify the index sheet output target, the output method, the index image arrangement method, the type of additional information to be output accompanying the index image, and the output method thereof. is there.

The outline of the index sheet output processing by the index sheet output unit 9 will be described with reference to the flowchart shown in FIG. First, a work area required for outputting the index sheet, that is, various buffers, output character strings, and the like are initialized. What is this string?
For example, the index sheet ID information is formed as a character string of volume information of the storage medium, a date, a serial number (initialized to 0), and an array of directory names (depending on the mode).

The index sheet ID information is for collating the index sheet with the storage medium when the index sheet is used. In the following description, this ID information is always output on a sheet (paper). Although described, it is also possible to substitute this by a method of inputting the relevant information from the operation unit 2 without outputting it on the sheet.

When the work area is initialized, the process for forming the index sheet image is started. In this process, first, the storage unit 3 stores the directory designated as the output target (all directories if the output target is not designated).
The storage media are sequentially taken out. Then, it is judged whether or not the target directory is ended, and if it is ended, the “image image output process” is executed and the process is ended. Judgment is made and "processing for the directory" is performed until the page breaks in the directory, then the next target directory is taken out, and the above-mentioned processing is repeated.

When the page break occurs in the directory, the "image image output process" and the work area re-initialization are performed, and then the "process for the directory" is performed. Then, the next target directory is taken out and the above processes are repeated.

"Processing for directory" is shown in FIG.
As shown in the flow chart, the files in the respective directories taken out from the storage medium are taken out in order, the file information and the index image image are taken out in order, and "expansion of the index image image" is performed. That is, the extracted index image images are sequentially expanded in the index image image buffer.

If the index image image buffer becomes full in the middle of the process, the index image image is sent to the printer section 5 by the "image image output process", and an image is formed (printed) on the paper and the index image is printed. Eject as a sheet. After that, the index image image buffer is cleared and the index sheet ID is updated (the serial number in the ID information is incremented).
And the above processing is continued.

When all the files are retrieved from the directory, the routine returns to the routine of FIG. 17 to retrieve the next target directory, all the directories to be processed are completed, and the index image remains in the index image buffer. In this case, the output process of the index image image is performed and the process ends.

[Expansion of index image]
As shown in the flow in FIG. 19, the index image development position is calculated, and the index image data is developed by applying a predetermined modification to the calculated index image development position.

In the "image image output process", as shown in the flow chart of FIG. 20, after the index sheet image is developed into an image and printed on the front surface of the sheet, the image portion of the index sheet image is reversed right and left. An index sheet image is constructed, the index sheet image is developed into an image, printed on the back side of the above paper, and discharged.

The index sheet output mode will be described in more detail. By pressing the index output key 34 of the operation unit 2 shown in FIG. 3, the mode for defining the index output unit 9 is set. Then, in the display / input device 21 having a touch panel, for example, as shown in FIG.
The "index sheet output mode setting screen" as shown in 1 is displayed. When the start key 22 is pressed or the "output" guide position on the screen of the display / input device 21 is touched, the index sheet output process is performed.

When the screen of the display / input device 21 is in the display state shown in FIG. 21, by touching the display portions of "directories 1 to 8", the directory to be output of the index sheet is designated / released (ON). / OFF)
it can. When the start key 22 is directly pressed after the directory is designated, the index sheet output process is performed while keeping the designated state.

Further, touching "all directories" will specify all directories. In FIG. 21, each shaded guide display indicates a designated state. Therefore, in the example shown in FIG. 21, all directories are designated.

Alternatively, when a command for setting the output target directory is issued through the operation unit 2, the index sheet output unit 9 accesses the storage unit 3 and reads all directory information to read the directory name, last write time, etc. Information may be displayed on the display screen of the operation unit 2 and presented to the user, and the user may set the output target directory by sequentially inputting the numbers of the displayed directories.

Next, the designation of the output format will be described.
In the display state shown in FIG. 21, by touching each guide display for designating an output format, each output format of paper, image size, image array, and directory page break can be designated.
Selection of paper, that is, a paper feed cassette can be set by pressing the paper selection key 28 shown in FIG. 3 in the display state shown in FIG. 21, and the setting state is displayed at the bottom of the screen.

The size of the image is designated by touching the guide area corresponding to the size of the image and using the ten keys 26 to specify the number of images to be accommodated on one sheet. Other specifications can be specified on the image array detail screen. The array of index images is
The guide display of "other (detail screen)" is touched to display the menu, and detailed designation can be performed on the screen, but the description of the screen and the like will be omitted.

By touching the guide display of “ON” or “OFF” in the directory page break area, ON / OFF of the page break can be designated for each directory. By touching the "help" guide display on the screen of FIG. 21, detailed information of the directory can be obtained.

When a directory is selected on the screen of FIG. 21 and the guide display of "file index sheet output" is touched, the screen of the display / input device 21 is changed to "file index sheet output mode setting screen" shown in FIG. It changes to ". Therefore, the file to which the file index is output is specified by touching one of the guides in the file name list (files 1 to 10) displayed side by side on the left side of the screen. If the previous file name does not fit on one screen, up and down arrows are displayed as shown in the figure, and the file name can be scrolled.

The designation of the output format is almost the same as the case of the index sheet output, but the file page break designation is made instead of the directory page break designation. If you touch the "Help" guide display, detailed information in the file will be displayed.

Next, the index sheet ID will be described. The index sheet ID is formed centering on the volume information of the storage medium. FIG. 23 shows an example of the logical structure of the index sheet ID. Further, examples of printed index sheet ID images are shown in FIGS.
Show.

The index sheet ID information is formed as a character string of the volume information of the storage medium, the last writing time (year, month, day and time), the serial number (initialized to 1), and the array of directory names (depending on the mode). As the character information, an image is formed on the index sheet 16 and output as shown in FIGS. However, the following differences occur depending on the index target image and the output form.

In the case of all directories, the directory names are arranged in a null character string as in the example shown in FIG. If the target directory is specified, then FIG.
As in the example shown in (1), the sequence of the names (character strings) of the designated directory and the sequence of the designated directories are configured. The punctuation mark "," is used as the character that separates the sequence. in this case,
Do not allow punctuation in the directory name string.

However, when the page break is specified, the area where the directory names are arranged becomes the character string of the directory name that is the target at that time,
The serial number is reinitialized each time the target directory changes.

The index sheet ID image image is
The index sheet ID information represents each area as a character string and is expanded as a character image, which is expanded at a predetermined position when the index image buffer is initialized. That is, printing is performed at a predetermined position on the index sheet (a portion near the upper edge of the sheet 16 in the example of FIGS. 24 and 25).

In order to form and output an index sheet, various buffers necessary for outputting an index sheet, character strings for output, etc. are first initialized as described above with reference to the flowchart of FIG. . For example, the index sheet ID information is formed as a character string of the volume information of the storage medium, the date and time, the serial number (initialized to 0), and the array of directory names (depending on the mode).

Further, the directories to be indexed are set in the target directory array. If the directories to be indexed are all directories (not specified), set all directories. this is,
This is done when specifying the output target directory. Then, the target directories are taken out one by one from the target directory array, and the following processing is performed.

If there is a directory page break designation,
Output processing of the remaining image is performed. In this process, it is first checked whether or not there is an index image image in the index image image buffer. This check can be easily performed by checking the index image counter described later. As a result, only when there is an index image image, the contents of the index image image buffer are sent to the printer section and printed out on paper.

After that, the work area is re-initialized to clear the index image image buffer,
The serial number of the index sheet ID information is set to 1, the directory name is set to the current target directory name, and the index sheet ID image image is expanded to the specified position in the buffer. Also, an index image counter for determining the position where the index image is developed is initialized.

Finally, processing for the directory (processing for files in the directory) is performed. When all the processing of the target directory is completed, the remaining image image output processing is performed, and the index sheet output processing is terminated.

The process for the directory is performed first in FIG.
The files are read from the directory one by one, as outlined by the flowchart in FIG. That is,
An index is extracted from the directory in the storage medium to the file information, and the file information is accessed to extract the file name, time stamp, password, comment information and index image information. And
Perform the following processing, and if all have been processed, end.

The index image images in the index image information are taken out one by one, and the target index image is expanded. At this time, the value of the index image counter is incremented each time one index image is formed, and when the value reaches the specified value, the index image image buffer is full,
The contents of the index image buffer are sent to the printer and printed out on paper.

After that, the index image image buffer is cleared, the serial number of the index sheet ID information is incremented, and then the index sheet ID image image is expanded to the specified position in the buffer. In this index image image expansion processing, as shown in the flowchart of FIG. 19, the expansion position of the index image is determined based on the index image counter, and the image is expanded at that position. In this embodiment, the size of the index sheet and the size and orientation of the index image are fixed.

FIG. 26 shows a conceptual diagram of the index sheet developed in this case. In this figure, a is the page top margin, b is the page left margin, c is the top area margin, d is the index sheet ID image area (fixed area), and IPU1 to IPU20 are each one index image area. Is shaded. e is the vertical length of the one area, f is also the horizontal length, g is the upper margin within the area, h is the left margin within the area, and i is the actual developed area. .

In this example, the number of expansions of the index image area in the index sheet 16 in the horizontal direction is 5, and the number of expansions in the vertical direction is 4. In this method, the number of expansions in the horizontal direction and the number of expansions in the vertical direction are constant. The size of one index (for example, 10% of A4 size
The size of the area for expanding the index image (the size of the area with left and right margins) is also determined accordingly.

First, the method of determining the expansion position will be described. The development relative position is obtained from the value of the index image counter by the following formula. Relative column: Index image counter% Number of horizontal expansions (% is remainder operator) Relative row: Index image counter ÷ Number of horizontal expansions +1 (÷ represents closed division by integer)

Therefore, the start position of the index image expansion area is as follows. X: page left margin + horizontal length of one area x (relative column-1) Y: margin on page + height of index sheet ID area + vertical length of one area x (relative row-1) However, the actual developed position in the area is the position obtained by adding the left margin in the area and the upper margin in the area to these X and Y.

The target index image is compared with the size when expanded and the size as the index image to be expanded in the buffer, and is reduced or expanded at an appropriate magnification. The up / down determination unit also determines up / down. When the paper direction matches the index image direction, the downward image is rotated 180 degrees and developed. The upward image is expanded as it is. If the paper direction does not match the index image direction, the downward image is rotated clockwise by 90 degrees and the upward image is rotated counterclockwise by 90 degrees. This makes it possible to align the directions of the images.

In the index image image output processing (residual image output processing), the index sheet image is first printed by the printer unit 5 as shown in the flowchart of FIG.
In, it is developed as an image on paper and fixed as an output image. Next, after the following processing is applied to the image buffer in the index sheet output unit 9, the paper is inverted in the printer unit 5, the image is developed and fixed on the image non-formed surface, and then discharged.

Here, the processing applied to the image buffer is left-right reversal of the position of the index image development area. Specifically, it is realized by replacing the Nth data from the left and the Nth data from the right in each row. However, N is the number of expansions in the horizontal direction from 1/2
Change in order. As a result, as shown in FIG. 27, index sheet images in which the relative positions of the index images are reversed are formed on the front and back sides.

Thus, the process is performed when the index sheet is placed on a pressure-sensitive reading means such as a touch panel, the index image to be selected is input by applying pressure with a finger, and the image is directly read by the reading means. Can be simplified. Of course, it is also possible to output exactly the same thing on the front and back sides and correct it when using the index sheet. Needless to say, it is also possible to output on only one side of the paper and operate it through the operation unit 2.

Next, the output of the file index sheet will be described. The index sheet outputs the index image of each file to the directory, whereas the file index sheet outputs the image of each page in the file to the file instead of the index image.

Therefore, the file name is entered in the directory area of the ID area. In the process of expanding the index image image, each page of the target file is converted into an index image image and expanded. that time,
ADF read files are processed in the reverse order of reading.

The file index sheet output is shown in FIG.
The mode is switched to the file index sheet output mode by using the mode switching key 24 of the operation unit 2 shown in FIG. However, if it is not specified, when the start key 22 is pressed, a selection request screen is displayed to prompt input. Further, at the time of processing the index sheet use command, it is possible to request the file index output after selecting the file by the index image.

28 and 29 show flowcharts of the file index sheet output processing. FIG. 28 shows FIG.
It is almost the same as the process of 7 index sheet output,
The "directory page break" check is changed to "file page break" check, and the "process for directory" is changed to "process for file".

As shown in FIG. 29, the processing for the file is performed by checking whether or not the ADF is used.
When the ADF is used, the extraction order of the image images in the file is set in the reverse order, and when the ADF is not used, it is set in the normal order. Then, the image images in the file are taken out in the set order, and the following process is repeated until all the processes are completed.

It is checked whether or not the file index image image buffer is full, and if it is not full, the image image is expanded in the file index image image buffer. When the file index image image buffer is full, the image image output process (common to the case of index sheet output) is performed, the file index image image buffer is cleared, and the file index ID is updated and expanded. File index Image Expands a new image in the image buffer.

The file index sheet ID area is constructed as shown in the first line of the structural example shown in FIG. 30 in order to distinguish it from a normal index sheet. An output example of the file index sheet ID image is as shown in FIG. The index sheet and the file index sheet can be distinguished by identifying the third area of this ID. Further, an identification code may be added, or different distortion correction marks may be attached.

(4) Index Sheet Utilization Process (FIGS. 32 to 50) Next, the index sheet utilization process executed when there is an index sheet utilization command in FIG. 7 will be described in detail. The instruction to use the index sheet is given by the index use key 35 of the operation unit 2 shown in FIG.
It is issued by pressing the start key 22 in the index sheet use mode with the (or mode switching key 24).

When the index sheet use mode is set by the index use key 35, the "digitizer selection mode screen" shown in FIG. 45 is displayed on the display / input combined device 21 and the "use digitizer" is displayed. By touching the guide position of "Sen",
The display switches to the "index sheet use mode setting screen" shown in FIG.

By touching the guide positions surrounded and surrounded by the oval frames, "use of file index sheet" and various settings regarding the used index sheet can be performed. After the setting, when the start key 22 is pressed, an instruction to use the index sheet is issued, whereby the processing according to the flowchart shown in FIG. 33 is performed.

In this process, first, the index sheet is read by the scanner section 4 in FIG. This is the reading of a general image image, and is the same as when a document is input. Then, the image image (image information) is stored in the memory in the index use operation unit 10.

Next, the index sheet ID is recognized and read from the image image of the index sheet by the character recognizing means in the index sheet utilizing operation unit 10. The read index sheet ID is collated. Then, it is checked whether or not there is a contradiction or a problem between the information (information such as volume, date, directory, etc.) in the read index sheet ID and the storage medium in the storage unit 3.

If there is a contradiction or a problem as a result, an error or warning is displayed on the operation unit 2 to wait for confirmation, and the user's instruction or response is requested. The user replaces the storage medium, replaces the index sheet, corrects the character recognition, and gives a continuation instruction.

If there is no contradiction or problem, and if there is a continuation instruction even if there is any, it is checked whether or not a command is embedded in the index sheet, and if embedded, the command is interpreted and Confirm and perform processing according to the instruction. In this case, processing contents are displayed on the display / input device 21 of the operation unit 2 to request confirmation. When the command cannot be read, an image showing the position of the index image in the index sheet is displayed on the operation unit 2, and the user's command is requested and the command is followed.

Here, the collation of the index sheet ID will be described. The index sheet ID is checked from the image image of the index sheet read as a digital image, and the following processing is performed. First,
The index sheet ID image area (see FIG. 26) is cut out. Since the index sheet ID image area is constant with respect to the size and orientation of the index sheet, it can be easily cut out. Further, the correction is added in consideration of the positional deviation of the paper. For example, a correction pattern is printed on the index sheet and the correction is performed.

Next, the image is rotated according to the index sheet ID image area. Therefore, the correction amount and the rotation amount are calculated according to the position of the cut out index sheet ID image area. Next, the index sheet ID image area is recognized using a character recognition technique, and the following check is performed with the storage medium using the index sheet and the index sheet ID information.

1) Media ID (volume information) The problem is in the case of mismatch. 2) If there is a directory mismatch. 3) Last write time When the write time of the storage medium is new.

If there is a problem in the above check, on the screen of the display / input dual-purpose device 21 of the operation unit 2 shown in FIG. 3, the problematic inconsistent points, etc. are displayed as shown in FIGS. 34, 35 and 36. Display and ask the user to take action. At that time, if there is a means for generating a warning sound, a warning sound is emitted to call attention. FIG. 34 is an example of a display screen when there is a mismatch in volume information, FIG. 35 is an example of a display screen when a directory does not exist, and FIG. 36 is an example of a display screen when there is a discrepancy in the last write time.

The user touches any of the guide areas surrounded by the elliptical frame in these display screens to switch the storage medium disks for execution and index sheet replacement for execution. It is possible to select and instruct execution, correction, directory list display, or help as is.

As a result, if the storage medium is replaced by the user, when the start key 22 is pressed after replacement, the index sheet ID collation processing is executed. If the user's response is to replace the index sheet, the operation is restarted with the start key 22, and the processing is executed from the reading of the index sheet. If the user's response is to correct the read information, the corrected start key 2
The processing is continued by pressing 2. At this time, the character recognition unit may learn the character recognition information according to the correction information.

If the user's correspondence is as it is, if the media IDs do not match, the information that the IDs match is corrected and the process returns to the index sheet ID collation processing. In the case of a directory and the time, those that do not match are ignored and processing continues.

Next, the reading of a command from the index sheet will be described. Cut out the index image from the corrected screen. At this time, when the fixed index image area is taken as shown in FIG. 26, the cutout position can be determined by the relative position with the index sheet ID image area. If the file information is printed, characters are recognized from the image.

Further, the user's instruction is cut out from the image. The user's instruction is, for example, to individually enclose a specific index image (IPU) with a line of a designated color as shown by a thick line in FIG. 37, or to designate an unnecessary index image (IPU) as shown in FIG. You can do this by marking the cross with a colored line. Alternatively, the index image (IPU) may be marked with a special polarization color, or characters may be written to give an instruction.

These instructions are recognized by the image recognition technique to be separated from the index image, and which index image is given which instruction is stored.
If an instruction from the user is embedded in the index sheet, the instruction is followed. For example, in FIG.
As shown in FIG. 7, when the index image is surrounded by the line of the designated color, the file having the surrounded (selected) index image (IPU1, IPU4) is output.

Further, as shown in FIG. 38, when an index image is marked with a designated color x, it is interpreted as an instruction to delete the file. Correspondence between them is decided and processing is performed according to the correspondence. In this case, it is also possible to display which file has been selected on the display / input device 21 to request confirmation.

If there is no instruction from the user in the image,
The process is performed after waiting for the user's instruction from the operation unit 2. First, the cut out index images are further reduced and displayed on the input / display combined device 21. At this time,
The layout on the screen is equivalent to the read layout normalized to top, bottom, left and right. Alternatively, only the frame may be displayed instead of the reduced image.

If all the index images cannot be displayed on the screen of the display / input device 21 at one time, the screen shown in FIG.
As shown in, a mark indicating scrolling (upward arrow and downward arrow) is displayed, and the mark is touched to scroll. Nine square frames shown in the left half of the figure are the reduced images of the index images.

By touching this reduced image (frame) on the screen, the user can select a file having the image at that position as an index. This touch switch (by a touch panel) is a toggle switch, and when the selected image (frame) is touched, the selection is released. Also, an image (frame) that is not selected
Touch to add to the selection. This allows multiple files to be selected.

A numeric keypad may be used instead of the touch switch for selection. The selected index image can be distinguished from the unselected index image by highlighting it as shown by the thick frame in FIG. Further, by pressing the start key 22, it is possible to print each page of the selected file (the file in which the selected index image is matched by the matching described later). That is,
It is possible to perform the same processing as when each page is sequentially input and read.

It is also possible to instruct the output of the file index sheet by touching the "file index sheet output" guide position displayed in the screens shown in FIGS.

Alternatively, the file name and additional information of the selected file can be displayed by touching the "file name display" guide position. In particular, by outputting information such as the size and the both sides of the paper, it becomes possible to appropriately determine the output method (size of the paper and use of both sides) when outputting the file. It should be noted that in the display state as shown in FIGS. 39 and 40, the display / input dual-purpose device 21 can make settings relating to the copy mode such as double-sided use, paper size, and magnification, and reflect the settings at the time of output. it can.

In the matching of index images, the designated index image and the index image of each file in the storage medium are matched (upper and lower sides are normalized). This results in matching of digital images. A threshold is determined, and a file having an index image with a pixel ratio equal to or higher than the threshold is selected.

By the way, it is possible to provide a work area, store the most recently read index sheet image (most recent index sheet image), and enable processing equivalent to reading from paper. Also, the index sheet can be output.

The index use key 35 shown in FIG.
When the start key 22 is pressed while the file index sheet is being used by (or the mode switching key 24) and input from the display / input dual-purpose device 21, almost the same processing as the index sheet processing is performed.

In this case, the processing is performed assuming that the page in the file is designated instead of the file and the file is designated instead of the directory. If the identification code of the file index sheet is given, the normal index sheet processing and the file index sheet processing can be distinguished by the presence or absence of the code.

For the command to the file index sheet, for example, as shown in FIG. 41, a plurality of index images (IPUs) are collectively enclosed by a line of a designated color, and these index image groups are made into separate files. As shown in FIG. 42, it is possible to instruct the replacement or movement of the page order of individual index images (IPUs) by a line with an arrow of the designated color.

On the other hand, when the guide position of "Use digitizer" on the "Digitizer selection mode screen" of FIG. 45 is touched, the index sheet use mode using the digitizer is set, and in this state, the start key 22 is pressed. When is pressed, an instruction to use the index sheet using the digitizer is issued, whereby the processing according to the flowchart shown in FIG. 46 is performed.

In this process, first, the index sheet ID image area is read through the digitizer 12, and the read index sheet ID is checked in the same manner as described above. Then, it is checked whether or not there is a contradiction or a problem between the information in the read index sheet ID and the storage medium of the storage unit 3, and if there is, an error or warning is displayed on the operation unit 2 to wait for confirmation and use. The person's instruction or response.

If there is no inconsistency or problem, and if there is a continuation instruction even if there is any, it is checked whether or not there is a digitizer input. After confirming and performing the processing according to the command, it is judged whether or not the end command (occurs when the "end" guide position shown in FIG. 45 is touched) is input, and if it is not input. Returns to the judgment as to whether or not there is a digitizer input, and if so, ends the processing.

By the way, when the above-described processing is performed, since the index sheet ID on the index sheet and the images (index images) forming each index image image are on the same surface, when the index sheet ID is read. The index sheet must be turned inside out. At this time, since the index image cannot be seen from the back side, the desired index image cannot be pressed.

Therefore, the following processing may be performed. Since each processing is a portion directly related to each invention of claims 1 to 4, each processing will be sequentially described as an embodiment (first embodiment to fourth embodiment) of each invention.

In the first embodiment, as shown in FIG. 47, the index output unit 9 shown in FIG. 1 prints the same index sheet ID and a plurality of index images created as described above on the front and back sides of a sheet. An image is formed on the sheet and output as an index sheet.

Further, the coordinate information input section 1 of the digitizer 12
The processing of FIG. 46 is started in a state where the output index sheet is set to 2a with the surface thereof facing downward,
When it is determined whether or not there is a digitizer input, when one of the index images formed on the back surface (upper side) of the index sheet is pressed from above, Since the digitizer input is made, the command corresponding to the digitizer is interpreted and confirmed and processed according to the command.

That is, the pressed coordinate position is detected, and the corresponding index image image is recognized from the detected coordinate position. At this time, the y coordinate is unchanged, and the x coordinate is corrected by reversing the left and right arrays, so that the index coordinate and the position coordinate in the index sheet can be matched. After that, the image information of the document corresponding to the recognized index image image is taken out from the storage medium, and an image is formed on a sheet and output.

In the second embodiment, as shown in FIG. 48, the index output unit 9 reverses the left and right arrangement of the same created index sheet ID and a plurality of index images on the front surface and the back surface of the paper. An image is formed and output as an index sheet. However, it is assumed that the left and right margins are the same.

Further, the coordinate information input section 1 of the digitizer 12
The processing of FIG. 46 is started in a state where the output index sheet is set to 2a with the surface thereof facing downward,
When the process proceeds to the determination as to whether or not there is a digitizer input, the same processing as in the above-described first embodiment is performed. In this case, the index images formed on the index sheet set in the coordinate information input unit 12a have the left and right arrangements reversed on the front surface and the back surface. Therefore, the position correction processing as in the first embodiment is performed. You don't have to.

In the third embodiment, as shown in FIG. 49, the index output unit 9 places the created index sheet ID and a plurality of index images on the front surface of the paper,
Information about each document corresponding to the index sheet ID and each index image is formed on the back surface of the sheet, and is output as an index sheet.

At this time, the index image and the information (document name and number of pages) related to the document corresponding to the index image are formed by reversing the left and right arrangements on the front surface and the back surface of the index sheet. In addition, the coordinate information input unit 12 of the digitizer 12
When the processing of FIG. 46 is started with the output index sheet set to a in a state in which the front surface is set downward, and when it is determined whether or not there is a digitizer input, the same as in the second embodiment described above. Is processed.

In the fourth embodiment, as shown in FIG. 50, the index output unit 9 places the created index sheet ID and a plurality of index images on the front surface of the paper,
Information about each document corresponding to the index sheet ID and each index image is formed on the back surface of the sheet, and is output as an index sheet.

At this time, the index image and the information (document name and number of pages) related to the document corresponding to the index image are formed by reversing the left and right arrangements on the front surface and the back surface of the index sheet. Further, the layout or magnification of the index information or the information on the document is changed according to the content of the index information on the front surface of the index sheet and the information on the document on the back surface of the index sheet.

That is, when the information on the document is formed on the back surface of the index sheet, if there is a large amount of information on each document, the indent between the front index images is increased according to the amount, and The position and the position of the information on the back side of the document are matched so that the characters do not overlap.

At this time, if the information about the document is smaller than the width of the index image, the information about the document is aligned with the position of the index image. If the area width of the information about the document is wider than the width of the index image, adjust the indent between the index images according to the arrangement of the information about the document, and match the position of the front side index image with the position of the information about the back side document. Let

Further, the coordinate information input section 1 of the digitizer 12
The processing of FIG. 46 is started in a state where the output index sheet is set to 2a with the surface thereof facing downward,
When the process proceeds to the determination as to whether or not there is a digitizer input, the same processing as in the second and third embodiments described above is performed.

Although the embodiments in which the present invention is applied to a digital copying machine have been described above, other than that, the image reading means (scanner or the like) or the external information receiving means (host I / O).
The present invention can be applied to any image forming storage device (including an optical filing device) including an F storage device (F, etc.), an image storage device (optical disc device, etc.) and an image forming device (printer, etc.).

[0198]

As described above, according to the first and second aspects of the invention, the user sets the index sheet on the digitizer with the front side facing down, and the index information on the back side (upper side) of the index sheet is set. The image information of the document corresponding to the index information can be output by pressing and selecting the desired one, but the same index information is formed on the front and back surfaces of the index sheet. Therefore, the index information after setting the index sheet on the digitizer can be selected while observing the index information on the back surface, and the work efficiency is improved.

According to the second aspect of the present invention, when the index information on the back side of the index sheet is pressed, the pressed position and the coordinate position of the actual (front side) index information match. The calculation step of the process of estimating the coordinate position of the index information can be omitted, and the processing speed can be increased.

According to the third aspect of the present invention, when selecting the index information, the desired index information is more accurately selected not only by the image information of the document but also by the information about the document (document name, number of pages, etc.). Then, the image information of the corresponding document can be output. Further, by using the back surface of the index sheet, a small amount of paper surface can be effectively used, and the information amount of the index sheet can be increased.

According to the invention of claim 4, the layout or magnification of the index information or the information related to the document is determined according to the content of the index information image-formed on the front surface of the index sheet and the information related to the document image-formed on the back surface. Since the amount of information relating to a document is large and images cannot be formed in a fixed area or overlapping images are not formed, information can be sufficiently expressed.
