Electronic document filing apparatus.

0001This invention relates to a data processing appara­tus for executing data processing according to the menu displayed on a display screen and, more particularly, to a document filing apparatus performing operations simi­lar thereto.

0002In recent times, several electronic document filing apparatuses have been developed and put to practical use. A document filing apparatus converts the infor­mation, including character and pictorial information, printed on documents, into electronic document image data, and files the data in a recording medium of large memory capacity, such as an optical disk or magnetic tape.

0003While the conventional paper filing requires the availability of a large amount of document storage space, the electronic filing apparatus, on the other hand, requires very little space for storing optical disks or magnetic tapes. The electronic filing appara­tus can edit the document image data relatively easily, by categorizing or classifying the data into groups, and assigning a key word to each group. In addition, it can record and retrieve a number of items of data quite quickly and easily.

0004The prior art document filing apparatus can per­form a variety of operations such as data retrieval, data registration or recording, data deletion, and others. To operate the apparatus, an operator desig­nates or selects one of the above operations, as desired, whereupon the apparatus performs the desired operation. For example, when the operator designates "data retrieval", the apparatus then operates in the data retrieval mode, and having retrieved the desired document data from the recording medium, displays and/or print it.

0005When the data record mode is designated, the filing apparatus scans a document or documents, reads out the document data, and records it into a recording medium. Each operation mode of the filing apparatus is composed of many hierarchy sub-modes, which implies that in any of the operation modes, a given task can be accomplished only after the sub-modes have been performed. In addi­tion, in the prior art filing apparatus, a given task can be accomplished only by use of a specific designated operation mode. Because of this, when the apparatus completes every operation, it must set in the initial mode. Consequently, the apparatus cannot continuously operate in different modes, and its operating speed as a whole is rather low.

0006It is an object of this invention to provide a document filing apparatus capable of executing a plural­ity of processings, such as data retrieval and data record, with a few key operations.

0007A data processing device according to this invention comprises a memory unit for storing data to be recorded, a display unit for displaying the data stored in the memory unit, and a designation unit for designating se­lection works for selecting at least the memory unit and the display unit. When the memory unit and the display unit are operated, the display unit displays the selec­tion marks. A first detector detects that the selection marks have been designated, in selective sequence, by the designating unit, and a second detector detects the completion of the designation of the selection marks. A drive unit drives the memory unit and the display unit in the order in which the marks have been designated, in response to the detection signal of the second detector.

0008This invention can be more fully understood from the following detailed description when taken in con­junction with the accompanying drawings, in which: <ul id="ul0001" list-style="none"><li>Fig. 1 shows a block diagram of a document filing apparatus according to one embodiment of this invention;</li><li>Fig. 2 shows a display including a single document window on the display screen;</li><li>Figs. 3A and 3B show displays each containing four display windows;</li><li>Fig. 4 shows a display containing scanner pro­perties;</li><li>Fig. 5 shows a display containing printer pro­perties;</li><li>Fig. 6 shows a display containing display pro­perties;</li><li>Fig. 7 shows a display containing file properties;</li><li>Figs. 8 to 18 diagrammatically show transient phases of various document data transfer modes;</li><li>Fig. 19 shows a flowchart illustrating a flow of document data transfer operation;</li><li>Fig. 20 shows a designation table (a) and a transfer table (b);</li><li>Fig. 21 shows a flowchart illustrating a flow of document data transfer when a continuous document read­out mode is used; and</li><li>Fig. 22 shows a transient phase of document data transfer operations, using a function area with a func­tion for starting document data transfer processings.</li></ul>

0009In a document filing apparatus shown in Fig. 1, scanner 1 and printer 5 are connected to scanner/printer interface 2. This interface 2 is connected to image data buses (I) and (II), and control buses (I)ʹ and (II)ʹ. These buses (I) and (II), and (I)ʹ and (II)ʹ are coupled with image-emlarging/reducing circuit 6, character generator 11, and compander 12. Compander 12, coupled with optical disk 13, appropriately compresses and expands the document image data recorded and repro­duced to and from optical disk 13.

0010Image buses (I) and (II), and control buses (I)ʹ and (II)ʹ connected through image bus select controller 3 to memory data buses (I) and (II). Memory data buses (I) and (II), and control buses (I)ʹ and control buses (I) and (II) are coupled with image buffer memory 4, display memory 7, display controller 8, vertical/­horizontal converter 10 and two-dimensional address generators 15 and 16. These generators 15 and 16 are connected through address (ADRS) bus (I) to image buffer memory 4, and through address (ADRS) bus (II) to display memory 7. Display memory 7 is coupled with display controller 8 for controlling display 9.

0011Scanner printer interface 2, image bus 6, display controller 8, vertical/horizontal converter 10, charac­ter generator 11, compander 12, and two-dimensional address generators 15 and 16 are coupled via the CPU bus to CPU 14. The CPU bus is connected to CPU memory 17, interface 18, mouse 19 and keyboard 20.

0012In the apparatus shown in Fig. 1, the document image data read out by scanner 1 is loaded into the apparatus through interface 2, and stored via bus selec­tor controller 3 into image memory 4.

0013The document image data stored in image memory 4 is subjected to enlarging or reducing by the circuit 6, and stored into display memory 7, and is displayed by display 9 under control of display controller 8. When it is not necessary to enlarge or reduce the document image data, image-enlarging/reducing circuit 6 does not perform its operation, as a matter of course. The docu­ment image data is transferred from display memory 7 to image memory 4 in a similar way.

0014Fig. 2 shows an initial display on the screen of display 9 in the document filing apparatus according to this invention. As shown, document window 201 for dis­playing document images including characters is substan­tially centered in the display screen. Icons are arrayed in the right portion of the document window 201, and give an operator various necessary indications, such as image-enlarging and reducing, and rotation and scroll of the displayed image. These indications by the icons are designated by a mouse or related keys on the key­board. For example, if the "Enlarge" is designated, the document displayed within the document window is enlarged.

0015The display further contains a function area 202 provided in connection with function keys F1 to F10. The function area contains icons F1 to F10 indicating various devices for inputting and outputting documents such as a scanner, printer, display, and file. The functions of these icons F1 to F10 are: Scanner (F1): To enter the document data from scanner 1, and transfer it to another device. Printer (F2): To print the document data trans­ferred from another device, by printer 5. Display (F3): To display the document data trans­ferred from another device by display 9, and to store it into internal image memory 4. Further, this indicates that the document data is read out from internal image memory 4 and transferred to another device. File (F4): To record the document data trans­ferred from another device on the optical disk, and to read out the document data from the optical disk, and to transfer it to another device.

0016Many types of processings can be done by appropriately combining the above four devices repre­sented by F1 to F4, and transferring the document data between devices. For example, if the document data is transferred from the scanner (F1) to the printer (F2), the hard copy of the document can be obtained.

0017The document filing apparatus according to this invention can execute ten types of document data trans­fers, or ten types of document data transfer modes as given below, by appropriately combining the scanner (F1), the printer (F2), the display (F3) and the file (F4). <ul id="ul0002" list-style="none"><li>(1) Scanner (F1)/Display (F3); Mode 1 To enter the document data from scanner 1 and to display it on document window 201.</li><li>(2) Scanner (F1)/printer (F2); Mode 2 To enter the document data from scanner 1 and to print it by printer 5.</li><li>(3) Scanner (F1)/file (F4); Mode 3 To enter the document data from scanner 1 and to record it on optical disk 13.</li><li>(4) File (F4)/display (F3); Mode M4 To retrieve the document data from optical disk 13 and to display it on document window 201.</li><li>(5) File (F4)/printer (F2); Mode M5 To retrieve the document data from optical disk 13 and print it by printer 5.</li><li>(6) Display (F3)/printer (F2); Mode M6 Print out the document data within document window 201 by printer 5.</li><li>(7) Display (F3)/file (F4); Mode M7 To record the document data within document window 201 on optical disk 13.</li><li>(8) Scanner (F1)/display (F3)/printer (F2); Mode M8 To enter the document data from scanner 1, and display it on document window 201, and check and print it by printer 5.</li><li>(9) Scanner (F1)/display (F3)/file (F4); Mode M9 To enter the document data from scanner 1, display it on document window 201, and check and record it on optical disk 13.</li><li>(10) File (F4)/display (F3)/printer (F2); Mode M10 To retrieve the document data from optical disk 13, display it on document window 201, and check and print it by printer 5.</li></ul>

0018As seem from the above descriptions, most of the retrieving and recording processings of those filing processings can be made by transferring the document data among those devices such as the scanner, printer, display and file.

0019Actually, optical disk 13 is used for the file. Before the processings (1) to (10) above, it is necessary to open and close the optical disk. These processings are performed in the DB function in menu bar area 203 shown in Fig. 2. This area contains a display mode and an edition function. These are for executing the following processings. Display mode: Changes the number of document win­dows 201 displayed by display 9 be­tween 1 and 4, as shown in Figs. 2 and 3. Edition function: To apply to the document image displayed on document window 201 some editions, for example, composing, layout, text input, etc. DB function: To format, open and close optical disk 13, and to arrange all of the documents recorded on optical disk 13 under predetermined conditions, and to save the arranged document data into the file or to delete the document meeting predetermined conditions.

0020The scanner, printer, display and file have respec­tively their own properties concerning the document transfers. Property sheets for changing or checking the properties of these devices can be displayed by display 9. Figs. 4 to 7 show displays with these properties. These properties can be displayed by operating the func­tion keys corresponding to function select keys on keyboard 20. The properties can also be displayed by using mouse 19. In this case, a mouse cursor is moved to a desired icon, and the right button of mouse 19 is pushed and released from its pushed state (clicked). To erase the property sheet, key F9 or F10 is pushed on the keyboard. When using mouse 19 for property sheet erasure, the mouse cursor is set to the icon of F9 (confirmation) or F10(erasure), and the left button of the mouse is clicked.

0021The property sheet of the scanner is used for setting properties such as the size of an input document, document density, read-out resolution, and feed mode (book or ADF (automatic document feed) mode). The book mode enters the image data of one sheet of document. The ADF mode successively enters the image data of the documents contained in the ADF holder.

0022The property sheet of the printer is used for setting the property of the number of printings, for example. The display property sheet is used for setting a display time of document in document window 201. The display time is useful when scanner 1 is operating in the ADF mode. For example, when document data are successively transferred from scanner 1, the display of one sheet of document continues for this display time. When the display time terminates, a sequence of entering the next document starts.

0023In the property sheet of the file, display 9 displays the information indicating what number of documents are now stored in the file, and which document is now read out or written into. When the document is read out from the optical disk, the continuous mode or batch mode is selected. This is similar to the feed mode in the scanner property sheet.

0024Ten types of document data transfers as mentioned above will be described.

Mode 1

0025In the initial state, display 9 displays the image as shown in Figs. 2 and 3. Fig. 8 shows the operations and the transient phases of changing states of the function area when the document data transfer mode of scanner (F1)/display (F3) is performed. In the figure, mark Fx (where x = 1 to 10) indicates the operation to push a keyboard function key or the operation to click the left button by setting the mouse cursor to the icon corresponding to the function key within the function area.

0026In operation, icon F1, for example, is designated by the mouse cursor and at this designated position, the button of mouse 19 is clicked. In response to the click action, a marking frame is displayed on icon F1 (step (b)). Then, the mouse cursor is moved to icon F3 and the mouse button is clicked, and the marking frame is displayed on F3 icon. Under this condition, viz., when icon F3 is being indicated, if the mouse button is clicked again, the document data transfer from scanner 1 to display 9 starts. That is, when CPU 14 detects that the icon (i.e. F3) corresponding to the device finally designated has been designated two time, it outputs a signal (command) representing an execution of pro­cessing.

0027At this time, icons F1 and F3 are shaded, in step (d). Then, the document data is entered from scanner 1, and the document image is displayed on the document window 201 shown in Fig. 2. At the same time, the "next document" is displayed on icon F7 in the function area 202, in step (e). Under this con­dition, when icon F7 is designated by mouse 19 or keyboard 20, the document data is transferred from scanner 1 to display 9. When F10 icon (cancel) is designated, the document filing apparatus can be returned to the initial state, in step (f).

0028At any time, icon F10 can be designated. At the time points of steps (b) and (c), the designation of icon F1 or icons F1 and F3 is cancelled. At the time point of step (e), the document transfer from scanner 1 to display 9 is ended.

0029Generally, the document transfer is directed in the following way. In the order of the devices to which the document data are transferred, the icons corresponding to those devices are successively designated each one time. Finally, the icon corresponding to the last device is designated again. In turn, the document data transfer starts, in an execution signal from CPU 14. The designations already made can be cancelled any time by designating the cancel icon F10, before the document transfer starts.

Modes M2 and M3

0030Figs. 9 and 10 diagrammatically show the operation modes M2 and M3 of the scanner (F1)/printer (F2) and the scanner (F1)/file (F4). These operations are almost the same as the scanner (F1)/display (F3) operation. Only the difference resides in that the document data collected by scanner 1 is not displayed on display win­dow 201, but is printed out or recorded.

Modes M4 and M5

0031Figs. 11 and 12 are diagramatical representations of the operation modes M4 and M5 of the file (F4)/display (F3) and the file (F4)/printer (F2). In the mode M4 of Fig. 11, the file-to-display document data transfer is executed when icon F4 is designated one time, and then icon F3 is designated two times. In the mode M5 of Fig. 12, the file-to-print document data transfer is executed when icon F4 is designated one time, and then icon F2 is designated two times.

0032In the operations of the above modes M4 and M5 shown in Figs. 11 and 12, the steps (a) to (b) are the same as those of the previous modes. In step (e), one document is read out from optical disk 13. The read out document is displayed in document window 201 in the mode M4 of Fig. 11, and is printed out in the mode M5 of Fig. 12. Also in step (e), "Next page" and "Previous page" are displayed on icons F7 and F8. When the "Next page" appears, the counter, which indicates what document is read out when the file is read out, is counted up by one. When the "Previous page" appears, the counter is counted down by one. Then, the operation returns to step (d), and a similar document transfer is performed. When cancel icon F10 is designated, the document transfer is ended.

Modes 6 and 7

0033Figs. 13 and 14 show the operation modes M6 and M7 of display (F3)/printer (F1) and display (F3)/file (F2). The operations of those modes are similar to the above ones. The operations of modes 1 to 7 are for document transfer between two devices. The description to follow is the document transfer among three devices.

Mode 8

0034Fig. 15 shows a sequence of mode 8 operations of scanner (F1)/display (F3)/printer (F2). In this mode, icons F1 and F3 are designated each one time in a suc­cessive manner. Finally, icon F2 is designated two times. When CPU 14 detects that icon F2 has been designated two times, the document data is transferred through the route of scanner-display-printer.

0035Steps (a) to (e) are for directing the document data transfer. In step (f), the document is scanned by scanner 1, and displayed on the window 201. At this point, the document data has been transferred between the scanner and the display. Also in step (f), "Print" and "Reenter" are displayed on the icons F7 and F8.

0036Under this condition, the operator checks the docu­ment in the window. After seeing the document, if deciding that the density of scanner 1 is improper, he selects the scan property sheet shown in Fig. 4 and sets its properties again, and designates "Reenter" icon F8. Upon this action by the operator, scanner 1 scans the document at the new property again, and document window 201 displays the document. If deciding that the document in the window is satisfactory, the print icon F7 is designated, so that the document data is trans­ferred between the display and printer (step (g)). At this time, the icon F7 displays the "Next page"

0037When the icon F7 of "Next page" is designated, the operation returns to step (e), the mode 8 for the scanner-display-printer is executed again from the first step. When icon F10 of "Cancel" is designated, the document transfer operation can be stopped at any time point. The operation to display the property sheets of the printer, display and file, and to check and change the properties, is possible also at any time point.

Modes 9 and 10

0038Figs. 16 and 17 show a sequence of document data transfer operations of each of modes 9 and 10. Mode 9 transfers document data among scanner (F1), display (F3), and file (F4). Mode 10 transfers among document data among file (F4), display (F3) and printer (F2).

0039In the operation modes as mentioned above, the pro­perties of scanner 1 and file each indicates the book mode and the successive read-out mode. Every time one document is transferred, the step to check the displayed document is needed. This step corresponds to the steps (f) and (g) in Fig. 16.

0040The operation of the document filing apparatus when the property of scanner 1 is the ADF mode, will be described. The same thing is true for the operation when the file is in the batch read-out mode. Fig. 18 diagrammatically shows a sequence of document data transfer among the scanner (F1), display (F3) and file (F4) when the scanner is in the ADF mode. In this operation sequence, the steps (a) to (e) are for directing the document transfer. This mode is different from the above-mentioned one in that in step (e) "Stop" is displayed on icon F6. Unless the "Stop" icon is designated in step (e), scanner 1 scans and reads out the document data of all of the documents contained in the ADF holder of the scanner. Each of these documents is displayed for a predetermined period of time on document window, and then these document data are suc­cessively stored into optical disk 13.

0041The display time of document in the document window is set by the display property. When an operator designates the icon "Stop" in step (e), the document transfer is temporarily stopped, and function area 202 gives the display shown in step (g). Under this con­dition, if "Reenter" (F8) is designated, scanner 1 reads out the document data.

0042When the stop of document transfer is removed, and the document transfer is started again, icon (F6) of "Continue" is designated, and the operation returns to step (e). When the data transfer of the holder contained documents is completed, or when icon "Cancel" (F10) is designated, the document transfer is completed, the operation goes to step (f).

0043As described above, when using the document filing system according to this invention, the directions for retrieval, record or registration, and the like can be executed by merely designating three to four icons representing devices.

0044If the display mode in menu bar area 203 shown in Figs. 2 and 3 is designated, one and four document win­dows 201 can be alternately displayed. Four document image buffers corresponding to the four windows are pro­vided in the device represented by "Display" (F3).

0045In the scanner-display document data transfer, i.e., in the mode M1, when one document window is used as shown in Fig. 2, the document is displayed on the document window 201. When four document windows 201 are used as shown in Fig. 3, the document is displayed on the document window 201 containing the "Final" icon located at the top in the menu bar area.

0046In the display-printer document transfer, i.e., the mode M6, the document displayed on the document window 201 with the "Final" icon, is printed out. Of those document windows, only one icon can have the "Final" icon. Every time the space key onto the keyboard is depressed, this icon is shifted from one window to another window. With depression of space key, the "Final" icon is cyclically shifted among those four document windows. This allows the operator to display a maximum of four documents in desired document windows 201, and further to print the document in a desired document window 201 or to record it into optical disk 13. The icon indicated by "Final" can be represented by a black mark, white mark, or stripe mark, etc.

0047In the display of Fig. 3(a), the document window 201 marked "1" in the upper left on the screen is the input/output document window. In the Fig. 3(b) display, the document window with "2" in the right upper is the input/output document window.

0048The operations of the Fig. 1 circuit relating to the document data transfer operations as illustrated in Figs. 8 to 18, will be described referring to a flow­chart of Fig. 19. Tables to be used in the description of the operations are illustrated in Fig. 20. A designation table (a) holds the number of icons as designated by the operator, and the order of function numbers corresponding to the icons. A transfer table (b) holds the number of icons for the document transfer processings which can be made by the document filing apparatus, and the order of function numbers. These tables are referred to during the document data transfer processings. These tables (a) and (b) are stored in CPU memory 17.

0049In operation, when the power supply is turned on, the initial states at the respective portions of the document filing apparatus are set up according to a program stored in CPU memory 17. At this time, display 9 displays document window 201, function area 201, and menu bar area 203, as shown in Fig. 2. This display pattern data is the data as transferred from the CPU memory or an external floppy disk to the display memory 7. Under this condition, the data corresponding to any of icons F1 to F10 is designated and entered by means of the keyboard or the mouse 19 (S1). The entered data is checked by CPU 14 if it coincides with one of icons F1 to F4 (S2). If the answer is YES, CPU 14 checks if the function number corresponding to the input or entered data coincides with the last function number in the designation table (a) of Fig. 20 (S3). If NO, the same checks if the function numbers of three or more have been recorded on the designation table (S4). If the answer is NO, the number of icons in the designation table is increased by one, and the function number as designated and entered is written into the designation table. The marking frame is displayed on the icon corresponding to the function number recorded anew (S5). After this, the operation returns to step S1.

0050If more than three function numbers are stored in the designation table, viz., the answer is YES, the designation table (a) is cleared, and the marking frame of icon is erased (S6). If the designated and entered function number coincides with the last function number in the designation table, the order (e.g., F1 - F3) of the function numbers in the designation table (a) is compared with each of the orders (F1 - F3, F1 - F2, F1 - F4, ...) of function numbers in the transfer table (b) (S7). If the same order is found, the marking frame in the icon is erased (S8) and the document transfer processing is started in the order shown in the designa­tion table (a) (S9). For example, when the function numbers are stored in the designation table in the order of F1 - F3, the document is read out by scanner 1, and the document data is transferred to the image data bus, through scanner printer interface 2. The document data in display memory 7 is read out by display controller 8, and input to display 9, and displayed as a document image. Thus, the document data transfer from scanner 1 to display 9 is automatically performed.

0051Upon completion of the document data transfer, the designation table (a) is cleared (S10), the operation returns to step S1. If the order in the designation table (a) is not registered in the transfer table (b), the designation table (a) is cleared and the marking frame of the icon is erased (S6), and the operation returns to step S1. If the designated and entered data is F10 (S11), the designation table (a) is cleared, and the marking frame of the icon is erased (S6), and the operation returns to step S1.

0052If the designation table (a) stores the function numbers in the order of F1 - F3 - F4 corresponding to the document data transfer operation of Fig. 16, the document is read out by scanner 1, and the document data is transferred to the image data bus via scanner printer interface 2. The document data on the Image data bus is transferred through image bus select controller 3 to image buffer memory 4 and display memory 7. The docu­ment data in display memory 7 is read out by display controller 8, and input display 9, and displayed in the form of a document image. The document data in image buffer memory 4 is read out, and input to compander 12 via image bus select controller 3 and the image data bus. The document data is subjected to the companding processing in compander 12, and is input to and stored in optical disk 13 as the file. In this way, the document data 1 is transferred to display 9 and optical disk 13, from scanner 1.

0053The operation of the document filing apparatus to be described referring to Fig. 21 is the operation of Fig. 18 in which the mode of the first device in the document data transfer contains the ADF mode automa­tically feeding documents.

0054When the document data transfer processing starts, the CPU checks the read-out mode of the first device (the first device in the designation table (a)), for example, scanner 1, in the document data transfer. When this mode is the batch read-out mode such as the ADF mode, the following operation procedure will be per­formed. The CPU checks if the "Stop" icon is desig­nated. If the answer is NO, the CPU checks whether the document to be transferred to scanner 1 is present or not. If YES, a sequence of document data transfer processings are executed uninterruptedly (S3). For example, when the designation for the scanner, display and printer is made, the document data enter, the document display, and the document print are succes­sively executed in connection with the first sequence of document data transfer processings.

0055After completion of the first sequence of the document data transfer processings, the CPU returns to the control flow to check the designation and entering of the "Stop". The second and subsequent sequences of document data transfer processings will be continued uninterruptedly until the "Stop" is designated or the transferred documents in the first device run out. As the documents in the first device run out, the document data transfer processing ends.

0056When the "Stop" is designated (S4), the document data transfer operation is stopped till the next desig­nation and entering of data. When the "Continue" is designated (S4), the CPU returns to the control flow to check whether or not the document to be transferred is contained in the first device, and enters the control loop for the sequence of document data transfer pro­cessings.

0057In step S4 for designation and entering of data, the function select and F1 to F4 are designated and entered, the property sheets of the devices correspond­ing to F1 to F4 are displayed and the properties of these devices are checked and if necessary, changed (S5). The control returns to step S4.

0058In the above-mentioned embodiment, at the start of document data transfer, the icon corresponding to the finally designated device is designated two times. An alternative measure to start the document data transfer is illustrated in Fig. 22. In the measure, the icon F9 in function area 202 displays "Execution" for executing the data transfer. This icon F9 is designated by a mark cursor or related corresponding function keys on the keyboard. More specifically, in Fig. 22, to start the execution of the mode M3 of the scanner-file document transfer, the icons are designated in the order of F1 (scanner), F4 (file) and F9 (execution). After the start of data transfer processing, the "Execution" disappears in icon F9.

0059As described above, the document data transfer pro­cessing can be repeatedly executed uninterruptedly by setting the first device in the continuous read-out mode.

0060It is evident that this invention is applicable for other data processors such as CD-ROMs, word processors, and personal computers, in addition to the document filing apparatus. When it is applied for CD-ROMs, scanner 1 for document data entering is not required.

0061As described above, the number of steps for many operations, for example, document data retrieval, is reduced, and the operation shifts can be made smoothly.
