Description

  The present invention relates to a data processing apparatus, a data processing method, a data processing program, and a recording medium, and more particularly, a data processing apparatus such as a composite apparatus, a copying apparatus, a printer apparatus, etc. The present invention relates to a method, a data processing program, and a recording medium.

  In data processing devices such as printers, copiers, multifunction devices, scanners, and computers, image data of originals read by the scanner unit, wireless / wired communication lines such as networks, public lines, the Internet, dedicated lines, etc. After the input image data such as received image data is subjected to predetermined image processing, it is temporarily stored in a non-volatile memory, and the stored image data is printed out by a printer unit or via a communication line. Various output processes such as data transmission, facsimile transmission, and storage output in a large-capacity nonvolatile memory on the network are performed. For example, in a composite apparatus, conventionally, a user ID is added from the external information processing apparatus side or the operation display unit to image data whose input image data requires confidentiality (hereinafter referred to as confidential data if necessary). Then, the composite device temporarily stores the input confidential data in the nonvolatile memory and manages the confidential data based on the user ID. Then, when the authentication is completed by inputting the user ID or the like from the operation display unit at the time of output, the multifunction device checks whether the confidential data of the user ID that matches the input user ID is stored in the nonvolatile memory, Confidential data with a matching user ID is read from a nonvolatile memory and recorded and output (see Patent Document 1). In addition, the composite device not only stores confidential data but also temporarily stores input data in a non-volatile memory, and then reads it at a predetermined time to output and reuse print output, transfer output, and the like.

In recent years, it has been possible to perform data processing using a non-volatile memory such as a NAND flash memory (hereinafter referred to as memory data processing if necessary) without connecting a hard disk. Has a low-cost and small-sized data processing apparatus that has only an interface (I / F) for connection and can be expanded as necessary.

  However, in the above prior art, without connecting a hard disk, only a non-volatile memory such as a NAND flash memory is mounted so that memory data processing using the non-volatile memory can be performed, and the hard disk is connected. Non-volatile when a hard disk is connected later to a data processing apparatus that has a non-volatile memory and stores data in the non-volatile memory. The confidentiality of data stored in memory and the effective use of data are not taken into consideration, and the data storage capacity can be improved by connecting a new hard disk, but the confidentiality and use of data. In order to improve the property, it was necessary to improve.

  Accordingly, the present invention provides an image processing apparatus and data that appropriately performs processing of data stored in an existing nonvolatile memory when the removable nonvolatile memory is connected in addition to the existing nonvolatile memory It is an object to provide a processing method, a data processing program, and a recording medium.

In order to achieve the above object, the present invention writes the received data to the nonvolatile memory and performs data processing, and when connection of the detachable nonvolatile memory to the memory connection means is detected, Based on the memory information of the connected non-volatile memory and the data stored in the non-volatile memory and the type of data stored in the non-volatile memory, the data stored in the non-volatile memory can be transferred to the non-volatile memory It is characterized in that it is moved or deleted from the nonvolatile memory .

Further, the present invention may be characterized in that either or both of the memory capacity and the data processing speed of the nonvolatile memory and the detachable nonvolatile memory are used as the memory information .

When the HDD 100 is newly connected to the HDD I / F 9 in the state where the memory data processing is being performed using the NAND flash memory 8, the multifunction device 1 of the present embodiment is connected to the HDD 100 and the NAND flash memory 8. The data stored in the NAND flash memory 8 is moved to or deleted from the HDD 100 based on the memory information and the data type already stored in the NAND flash memory 8. In the following description, the operation processing of each block of the functional block diagram of the composite apparatus 1 shown in FIG. 5 will be described. However, as described above, the CPU 2 shown in FIG. Each part is controlled and executed based on the program.

  That is, as shown in FIG. 6, the multifunction apparatus 1 executes basic data control processing for determining data connection and determining data connection. As shown in FIG. 6, first, the HDD (hard disk) control unit 54 detects whether the HDD (hard disk) 100 is connected (step S101), and checks whether the HDD 100 is connected (step S102). ).

  If the HDD 100 is not connected to the HDD I / F 9 in step S102, the multifunction apparatus 1 shifts to a normal system standby state and ends the basic data control process (step S105).

  If the HDD 100 is connected to the HDD I / F 9 in step S102, the HDD control unit 54 checks whether the existing partition can be recognized in order to make the HDD 100 usable by the file input / output control unit 52. If the existing partition can be recognized, the existing partition can be used as a file system (file read / write or free space of the partition can be acquired). If the existing partition cannot be recognized, the ROM 3 Then, a partition is created in the HDD 100 according to HDD (hard disk) control information recorded in the NVRAM 6 and a size defined in the program so that it can be used as a file system. Then, the HDD control unit 54 notifies the document storage control unit 50 and the document movement control unit 55 through the file input / output control unit 52 that the HDD 100 is connected (step S103).

  The document movement control unit 55 moves the data already stored in the NAND flash memory 8 to the HDD 100, and in order to make the data on the NAND flash memory 8 unusable when the HDD 100 is connected, Instead of moving, a document moving / deleting process for deleting data of a specific document is performed from the NAND flash memory 8 (step S104), and then the process shifts to a normal system standby state and the basic data control process is terminated. (Step S105). In addition, including movement and deletion of data, it is expressed as movement / deletion as appropriate.

  Then, the multifunction device 1 performs the document movement / deletion processing on the document information such as the memory information of the NAND flash memory 8 and the HDD 100 and the type (data type) of the document (file) stored on the NAND flash memory 8. (Document information).

  First, document movement / deletion processing for moving / deleting a document based on the free capacity of the HDD 100 and the NAND flash memory 8 will be described with reference to FIG. When the multifunction apparatus 1 shifts to the document movement / deletion process, the document movement control unit 55 acquires the free capacity S1 of the HDD 100 via the file input / output control unit 52 (step S201), and the file input / output control unit. The free space S2 of the NAND flash memory 8 is acquired via 52 (step S202).

  Next, the document movement control unit 55 compares the free capacity S1 of the HDD 100 with the free capacity S2 of the NAND flash memory 8 (step S103). When the free capacity S1 of the HDD 100 is equal to or less than the free capacity S2 of the NAND flash memory 8, Since there is a possibility that the document stored in the NAND flash memory 8 cannot be moved to the HDD 100, the document moving / deleting process is terminated without moving the document.

  When the free capacity S1 of the HDD 100 exceeds the free capacity S2 of the NAND flash memory 8 in step S203, the document movement control unit 55 stores the file list table Tb2 stored in the ROM 3, NVRAM 6 or NAND flash memory 8 (see FIG. 4). ) Based on a document file (data) of a document file stored in the NAND flash memory 8, a predetermined type of document, for example, a confidential document is specified, and the data of the confidential document is read from the NAND flash memory 8. Acquired (step S204), and the acquired document data (for example, confidential document data) is moved to the HDD 100 or deleted from the NAND flash memory 8 (step S205).

  The data type to be moved / deleted is set in advance by operating the operation unit 16 or the like. FIG. 7 shows a case where the confidential document (confidential data) is the data type to be moved / deleted (document type). However, the data type to be moved / deleted is not limited to confidential data (confidential document), and any one of the above-mentioned reserved data (held document), accumulated data (accumulated document), and confidential data or A plurality of data types may be set as data types to be moved / deleted. In FIG. 4, the ROM 3, NVRAM 6 or NAND flash memory 8 stores a file list table Tb2 in which document information such as document names, document files and data types of data stored in the NAND flash memory 8 is registered. Referring to this file list table Tb2, the data to be moved / deleted among the data stored in the NAND flash memory 8 can be specified and acquired, but the data to be moved / deleted can be specified. The method is not limited to the method based on the file list table Tb2. For example, as shown in FIG. 8, a directory in which a document file is created for each data type of the nonvolatile memory 8 (in FIG. 8, NAND / confidential , NAND / pending, NAND / storage, etc.) And a file name (for example, NAND / confidential / AAA.doc) to which information (for example, NAND / confidential) indicating the document position (data storage position) on the NAND flash memory 8 is assigned as the file name of the data. Etc.). In this way, there is no need to create the file list table Tb2 and register the document information in the ROM 3, NVRAM 6 or NAND flash memory 8, and the document to be moved / deleted from the document storage directory of the NAND flash memory 8 Data in the (data) type directory can be acquired and moved to / deleted from the HDD 100. In addition, as a file name of a data file (document file) stored in the NAND flash memory 8, a file name to which a data type (document type) is added (for example, NAND./docs/AAA.doc. Confidential) is used. Also good. In response to a request from the document movement control unit 55, the document accumulation control unit 50 acquires a document file name of a document of the requested data type (for example, a confidential document) from, for example, the file list table Tb2 in FIG. By acquiring the file name under the directory (for example, NAND / confidential) corresponding to the requested data type on the NAND flash memory 8 through the file input / output control unit 52 and transmitting it to the document movement control unit 55, Specify the data (document) to be moved / deleted.

  Then, when all the data notified from the document accumulation control unit 50 as the object of movement / deletion is moved from the NAND flash memory 8 to the HDD 100, the document movement control unit 55 indicates that the data movement is completed. (Step S206).

  When the document storage control unit 50 creates the file list table Tb2 and registers the document information in the ROM 3, NVRAM 6 or NAND flash memory 8, the document storage control unit 50 stores the document information of the moved / deleted document in the file list table Tb2 ( When there is an output request for the moved data, the data is appropriately acquired and output (step S207).

  Next, document movement / deletion processing for moving / deleting a document based on a difference in transfer speed between the HDD 100 and the NAND flash memory 8 will be described with reference to FIG. In FIG. 9, the same step numbers are assigned to the same processing steps as the document movement / deletion processing of FIG. 7, and the description thereof is simplified.

  When the multifunction apparatus 1 shifts to the document movement / deletion process, the document movement control unit 55 acquires information of the HDD 100 connected to the HDD I / F 9 via the file input / output control unit 52, and acquires the acquired HDD 100. Referring to the HDD information table Tb1 (see FIG. 3) stored in the ROM 3, the NVRAM 6, or the NAND flash memory 8 based on the information indicating the manufacturer and model number of the HDD 100, the HDD I / F 9 The connected HDD 100 is specified and the transfer rate T1 of the HDD 100 is acquired (step S301). Note that the transfer rate T1 of the HDD 100 is not limited to the method of storing the HDD information table Tb1 in the ROM 3, NVRAM 6 or NAND flash memory 8 and referring to the HDD information table Tb1, and for example, at the time of shipment of the HDD 100. A method may be used in which the transfer rate previously written in a specific sector of the HDD 100 is acquired through the file input / output control unit 52, or data of a predetermined size is read from or written to the HDD 100 through the file input / output control unit 52. A method of acquiring the transfer rate from the time required for reading and writing data may be used.

  Next, the document movement control unit 55 acquires the transfer speed T2 of the NAND flash memory 8 (step S302). When the transfer speed T2 of the NAND flash memory 8 is previously written in the NAND flash memory 8 itself, the document movement control unit 55 uses the transfer speed T2 written in the NAND flash memory 8 as a file. When the transfer speed T2 of the NAND flash memory 8 is stored in the ROM 3 or the NVRAM 6, the transfer speed T2 is acquired from the ROM 3 or the NVRAM 6, or determined in advance by a program. It is obtained by referring to the numerical value.

  Next, the document movement control unit 55 compares the transfer speed T1 of the HDD 100 with the transfer speed T2 of the NAND flash memory 8 (step S303). When the transfer speed T1 of the HDD 100 is equal to or lower than the transfer speed T2 of the NAND flash memory 8, The document moving / deleting process is ended without moving or deleting the document.

  When the transfer rate T1 of the HDD 100 exceeds the transfer rate T2 of the NAND flash memory 8 in step S303, the document movement control unit 55 is stored in the ROM 3, NVRAM 6, or NAND flash memory 8 as in the case of FIG. On the basis of the file list table Tb2 (see FIG. 4), a document of a predetermined type, for example, a confidential document is identified from the document information of the document file stored in the NAND flash memory 8, and the confidential document Data is acquired from the NAND flash memory 8 (step S204), and the acquired document data (for example, confidential document data) is moved to the HDD 100, or the data is deleted from the NAND flash memory 8 (step S205).

  When the document movement control unit 55 moves all data notified of the movement / deletion from the NAND flash memory 8 to the HDD 100 or deletes it from the NAND flash memory 8, the data movement / deletion is completed. Is stored in the document storage control unit 50 (step S206), and the document storage control unit 50 creates the file list table Tb2 in the ROM 3, NVRAM 6 or NAND flash memory 8 and registers the document information. The document information of the moved / deleted document in the list table Tb2 is changed (step S207).

  Then, the composite apparatus 1 performs input data accumulation / output processing as shown in FIG. 10 based on whether or not the HDD 100 is connected to the HDD I / F 9. FIG. 10 shows a case where the input data is print data and the output request is print output for the sake of clarity.

  That is, when the data processing request acceptance loop is started (step S401), the multifunction apparatus 1 checks whether print data is received (step S402). When the print data is received, the received print data is stored in the document accumulation control unit 50. (Step S403), it is checked whether the HDD 100 is already connected (step S404).

S402 to S405). When the HDD 100 is connected in step S404, the multifunction apparatus 1 determines and determines whether the received print data is stored in the NAND flash memory 8 or the HDD 100, and the data is stored in the determined storage location. (Step S406), the process returns to step S402, and the same processing as described above is performed from the check of whether print data has been received (steps S402 to S406).

  If no print data is received in step S402, the multifunction apparatus 1 checks whether there is a print request for the stored document (step S406). If there is a print request, the NAND flash memory control unit 53 or the NAND flash memory control unit 53 The information on the data stored in the NAND flash memory 8 or the NAND flash memory 8 and the HDD 100 is read through the HDD control unit 54 and displayed on the display of the operation unit 16 (step S407).

  When the document to be printed is selected by the operation of the operation unit 16, the multifunction apparatus 1 reads the data of the selected document from the NAND flash memory 8 or the HDD 100, passes it to the data output control unit 57, and the printer engine 7. Then, the document is printed (step S408), the process returns to step S402, and the same processing as described above is performed from the check whether the print data is received (steps S402 to S408).

  If there is no print request for the stored document in step S406, the multifunction apparatus 1 determines whether the request reception loop is completed. If the request reception loop is not completed, the multifunction apparatus 1 repeats the request reception loop processing (steps S401 to S409). In step S409, when the request acceptance loop ends, the process ends.

  As described above, when the multifunction apparatus 1 according to the present embodiment writes received data to the NAND flash memory 8 and performs data processing, when the connection of the HDD 100 to the HDD I / F 9 is detected, the NAND flash memory Among data already written in the memory 8, a predetermined type of data such as confidential data requiring confidentiality, suspended data for which data output is suspended, and accumulated data temporarily accumulated prior to data output is represented by the data type Depending on the connection, data processing at the time of connection from the NAND flash memory 8 to the HDD 100 or deletion from the NAND flash memory 8 is performed.
