JP4630083B2 - Image processing apparatus and program used for the same - Google Patents

Description

  The present invention relates to an image processing apparatus (for example, a digital copying machine, a printer, etc.) that processes image data by a plurality of application programs. More specifically, the present invention is non-volatile capable of writing / erasing data that can be externally mounted. The present invention relates to file data management and a program used for the management in an image processing apparatus that enables function expansion by a program file stored in a storage medium (for example, an SD card).

  Conventionally, in a digital copying machine, a system controller has realized a copy function by controlling operations necessary for processing according to a copy application program. Such an application program is provided on a controller board such as a flash ROM or a DIMM. In general, the data is stored in the memory.

  Therefore, when a function is changed or added, the application program is upgraded. For example, Patent Document 1 shown below can be cited as a conventional technique for updating a program of an image forming apparatus by rewriting a flash memory built in the apparatus. In Patent Document 1, rewriting can be performed more efficiently by downloading from the server PC only the portion that differs between versions, without rewriting the entire program.

  By the way, in digital copiers such as MFP (Multi Function Peripheral) machines, additional functions such as printers and faxes that are combined with the expanded copy functions and combined with the copy functions can be supported by adding each application program to expand the functions. Makes it possible to plan.

  At that time, in place of a method corresponding to rewriting or adding a program stored in a flash ROM built in the apparatus (see Patent Document 1), in recent years, a removable large-capacity portable such as an SD (Secure Digital) card is used. With the spread of media, application programs and the like have been provided using SD card media.

In this case, the user can perform an operation according to the required application program by inserting the SD card medium storing the purchased application program into the SD card mounting slot of the main body. When the additional function is an option, the method of expanding the function by the SD card medium has an advantage that it can be easily handled without worrying about the lack of capacity of the flash ROM built in the apparatus.
Japanese Patent Laid-Open No. 2002-14833

  However, since the number of slots provided for inserting SD cards is limited, SD cards exceeding the number of slots cannot be simultaneously installed. For this reason, a situation occurs in which all application programs required by the user cannot be used. This situation is a situation where, for example, some applications cannot operate due to insufficient number of slots.

  As the simplest method of this measure, a method of preparing the number of SD card slots as many as the number of applications can be considered. However, this method is not a perfect measure because it causes an increase in cost due to an increase in slots and a problem with the physical size of the main body of the image forming apparatus.

  As another countermeasure, there is a method in which a plurality of types of applications are stored in the SD card in advance, and the types of SD cards provided to the user are kept within the number of slots. However, according to this method, an application that is not required by the user of the apparatus is provided.

  Therefore, with the aim of making it possible to use as many applications as necessary within the range of the number of SD card slots provided in the main unit, files stored on multiple SD cards are combined into one, and the capacity of the card is reduced. Proposals have been made to solve the above problem by a method for storing necessary data by making the maximum use.

  However, in this prior art, it is not assumed that the processing is interrupted after the replication is started in the file replication performed in the process of combining the files into one. Therefore, for example, when the copying process is interrupted due to an unexpected accident such as a power failure, an unnecessary file generated by the copying remains in the storage medium. Therefore, a new problem arises that hinders the original purpose of using as many applications as possible, and this problem remains unresolved.

  The present invention makes it possible to attach a non-volatile storage medium capable of writing / erasing data, such as the above-mentioned SD card, from the outside, and function expansion by adding a program file using such a storage medium The present invention has been made in order to solve the above-described problems that occur in the prior art, and the problem to be solved is that even when a replication process performed between the storage media is interrupted due to an accident or the like, the storage media It is to restore the state in which the effective use of the storage area is not impaired. Further, it is a further problem to perform management that can cope with a situation in which replication processing is interrupted due to a cause such as a power failure and the intended recovery cannot be performed immediately.

  The invention of claim 1 is an image processing apparatus in which a processing function is expanded by executing a file program stored in a non-volatile storage medium capable of writing and erasing data which can be externally mounted. A plurality of mounting means for mounting the storage medium, a replication means for copying a file of one storage medium mounted on the mounting means to another storage medium mounted in a similar manner, and managing a replication process An image processing apparatus comprising: a managing unit that deletes a file on a duplication destination storage medium that is in the middle of duplication when the management unit detects that the duplication process is interrupted.

  According to a second aspect of the present invention, in the image processing apparatus according to the first aspect, the management unit creates a log file that records file information to be copied in the copy destination storage medium, and performs a copy process. Is used to identify the interrupted file.

  According to a third aspect of the present invention, the image processing apparatus according to the second aspect further comprises means for erasing the log file created by the management means upon completion of erasure of data being duplicated in the duplication destination storage medium. It is a feature.

According to a fourth aspect of the present invention, in the image processing apparatus according to the second or third aspect, a means for checking the existence of a log file created on the storage medium at an arbitrary timing is provided, and the log file exists. And a means for deleting a file recorded in the log file.
According to a fifth aspect of the present invention, there is provided an image processing apparatus in which a processing function is expanded by executing a program of a file stored in a nonvolatile storage medium capable of writing / erasing data that can be externally mounted. A computer for controlling the operation includes a procedure for copying a file stored in one of the storage media to another storage medium, and a log file for recording file information to be copied in the copy destination storage medium. The procedure for creating, the procedure for detecting the occurrence of the interruption of the replication process in the process of the replication process, and the file information recorded in the log file when the occurrence of the interruption of the replication process is detected is specified. A program for executing a procedure and a procedure for erasing a specified file from a copy destination storage medium.

  According to the first and fifth aspects of the present invention, it is possible to identify a file that is in the middle of duplication when the occurrence of processing interruption in the duplication process is detected, and to erase the identified file from the duplication destination storage medium. Since there is a means, unnecessary files do not remain in the storage medium, the storage area can be used effectively, and the use of the maximum file function is improved, thereby improving the usability of the device. It becomes possible to make it.

  According to the inventions of claims 2 to 4, since the log file for recording the file information to be copied is created in the copy destination storage medium, the copy process is interrupted in any form. Even if it happens (for example, when it happens due to a power outage and the situation where the intended recovery cannot be performed immediately), the recovery process can be handled. In addition, since there is a means to check the existence of log files and automatic deletion of unnecessary files, it is not necessary to instruct the user to delete unnecessary files and to perform operations, improving the usability of the device It becomes possible to make it.

  The present invention will be described based on the following embodiments shown with the accompanying drawings. The embodiment shown here is an example in which the image processing apparatus of the present invention is applied to a digital copying machine.

  FIG. 1 is a schematic diagram showing a program configuration of a digital copying machine according to an embodiment of the present invention.

  The digital copying machine of the present invention is a so-called MFP (Multi Function Peripheral) machine in which a plurality of functions such as a copy, a printer, a FAX, and a scanner are combined.

  The configuration of the control unit includes the engine board 20, the FCU board 30, the operation panel board 40, and the controller board 10 that is connected to each of the control boards and controls the operation of the entire apparatus as a main control unit.

  The engine board 20 is a control board that controls an engine unit included in the apparatus. The FCU board 30 is a control board that controls the facsimile transmission / reception unit. The operation panel board 40 is a control board that controls the operation of the operation unit.

  Among the control boards described above, the controller board 10 that performs main control includes various controller control programs (ECS, IMH, SCS, SRM, etc.) and application programs such as a copy and a document box. . These application programs 16 are stored in a flash ROM 15 mounted on the controller board 10.

  An operation panel control firmware 41 is mounted on an operation panel board 40 connected to the controller board 10 through a synchronous serial line. Further, an FCU board 30 that performs FAX document reception / transmission processing and an engine board 20 that performs operations such as scanner reading, conveyance of printing paper, and writing of image data are connected through the controller board 10 and a PCI bus line. Yes. An FCU firmware 31 is mounted on the FCU board 30. The engine board 20 includes a plotter firmware 21 and a scanner firmware 22.

  Further, the controller board 10 includes SD card slots 11 and 12 for inserting an SD (Secure Digital) card. The SD card is a large-capacity portable storage medium, and a flash memory, which is a nonvolatile storage medium capable of writing / erasing data, is a card type. Here, the application program file is used to provide the SD card. When the SD card 50 is inserted into the SD card slots 11 and 12, the apparatus main body can be operated according to an application program stored in the SD card 50.

  In the present embodiment, as shown in FIG. 1, the controller board 10 is equipped with two SD card slots 1 11 and SD card slots 2 12. Here, the program file provided by the SD card is a program file necessary for an additional function other than a function such as copying that is normally provided. Two program files of a printer application and a scanner application are provided by one SD card 51. A program file for a FAX application is provided by another SD card 52. Furthermore, in order to expand the types of fonts that can be used in the printer application, an SD card 53 that stores font data is also prepared separately. When using the program supplied by the SD card 50, the user selects an SD card that he / she wants to use from these SD cards 51 to 53 and installs it in the SD card slots 11 and 12 of the controller board 10. The function of the copying machine can be expanded.

  The apparatus configuration of the digital copying machine other than the program configuration which is the characteristic part of the configuration of the present invention described above with reference to FIG. 1 is the same as the configuration normally provided in a digital copying machine having a known composite function. Since it can be implemented, the description is omitted here.

  Next, management of program files provided by the SD card employed in the copying machine will be described.

  When a program file is provided from an SD card, as shown in the above embodiment (see FIG. 1), the number of SD card slots provided in the main body is limited (two are illustrated). Therefore, in order to make it possible to use as many applications as necessary within the constraints, it is necessary to store file data using the capacity of the card as much as possible. For this reason, in this embodiment, an integrated processing function is used to combine files stored in a plurality of SD cards into one.

  FIG. 2 is a diagram for explaining processing for integrating files stored in a plurality of SD cards. The SD card shown in FIG. 2 shows the result of integrated processing. Specifically, the SD card shown in FIG. 2 integrates the SD card 51 storing the printer application and the scanner application shown in FIG. 1 and the SD card 52 storing the FAX application into FIG. As shown, an example in which three applications are collected on one SD card 51 is shown. In this way, by integrating the files using the function of grouping in one SD card, it was originally impossible to operate simultaneously without having to install three or more types of SD cards. All the operations can be performed by collecting application programs and data, which were impossible in the form shown, as shown in FIG. Furthermore, if the storage capacity is sufficient, it is possible to operate with one SD card by repeatedly performing the integration process.

  The integration processing for combining files stored in a plurality of SD cards into one requires processing for copying program file data between SD cards, and file management associated with the processing (details will be described later). A function for performing such processing is prepared in the controller board 10. This function is installed as one of processing programs driven by the CPU of the controller board.

  The data replication function between SD cards itself can be implemented by applying a function generally used when data is replicated between memories. When the integration process is actually executed, the processing program is started by performing an input operation for using this function on the display screen of the operation panel under the control of the controller board 10. The user specifies the file to be copied and the copy destination SD card from the program files stored in the copy source SD card on the operation screen, and instructs the program as part of the integration process. The replication process is performed accordingly.

  With the above program file integration processing, it becomes possible to store file data by making maximum use of the capacity of the card. However, if the processing is interrupted in the middle of the program file integration processing, unnecessary data may occupy the storage area. This situation may cause the problem of hindering the original purpose of maximizing the capacity of the card.

  In this embodiment, even when the replication process executed as part of the integration process is interrupted, especially when the replication process performed between SD cards is interrupted due to an unexpected accident such as a power failure, the storage area of the storage medium is valid. Take measures to enable recovery to a state where usage is not compromised.

  This means manages files in the middle of replication when replication processing is interrupted, thereby enabling erasure of data remaining in the replication destination SD card as unnecessary data and recovery of the storage area. Is.

  The method for managing files in the middle of replication and enabling recovery from interruption of replication processing is based on the following method. In other words, this method creates a log file that records the file information that is the target of the replication process, and when the replication process is interrupted during the replication process, the file information recorded in the log file is in the middle of the replication process. In this method, a certain file is specified, and unnecessary data is erased from the copy destination storage medium based on the specified file information.

  Here, a file integration process including a procedure for enabling the recovery process from the interruption of the replication process will be described according to the embodiment.

  Since the copying machine normally has a function of checking the stored program file, a function for performing file integration processing is added to a part of the function. Then, the recovery process can be performed by a method that can use this function. For example, a method of providing a function key for file integration processing on the screen of the operation unit for displaying a list of program files stored in the SD card at the time of file check, and starting this processing by pressing the user's key. Can be adopted.

  FIG. 3 shows a flowchart of the integration process of this embodiment that enables recovery from the interruption of the replication process. Referring to the processing flow shown in the figure, first, the CPU confirms execution of SD card integration processing (step S101). That is, according to the above example, the CPU confirms the execution instruction by an operation input to the function key of the file integration process provided on the screen of the operation unit. At this time, since a plurality of SD cards are mounted, the user needs to specify an SD card to be duplicated (integrated), that is, a duplication source and a duplication destination SD card.

  When execution of the SD card integration process is instructed by the user (step S101—YES), the CPU next determines whether or not the SD card integration (duplication) process can be executed (step S102).

  In this embodiment, this determination is as follows. ~ 5. Perform according to the conditions.

1. 1. Is the SD card properly installed in the slot? 2. Is the remaining SD card storage capacity sufficient? Is the copy destination SD card prohibited from being written? 4. Is the copy source SD card copyable? Whether or not a file with a common name exists in the SD card to be duplicated. Based on these conditions, the CPU determines whether or not the SD card duplication processing can be executed. At that time, if any one of the conditions is not satisfied, the CPU determines that the integration is impossible (step S102-N0), and exits this processing flow without performing the SD card integration processing.

  On the other hand, the above 1. ~ 5. If all of the above conditions are satisfied, the CPU determines that integration processing is possible, and as a replication target file, the log file for integration processing (name) that lists the list names of all files in the source SD card : Gw_logfile.log) is created (step S103). In addition, although the integration process in this embodiment shows the example which integrates all the files in an SD card to other SD cards collectively, you may make a part of program files into object. In that case, it is necessary to specify a target file by a user's selection operation.

FIG. 4 illustrates a log file created at this time. The log file shown in FIG.
・ Printer_aplication.prg
・ Printer_aplication.data
・ Scanner_aplication.prg
・ Scanner_aplication.data
As an example, there are four types of files in the copy source SD card. As shown in FIG. 4, the boundary between the file name and the file name can be distinguished by listing the four types of file names while separating them with “:”.

  Next, the CPU stores the created log file in the copy destination SD card (step S104) and allows it to be used as management information. The reason why the CPU stores the log file in the copy destination SD card is that the copy process is interrupted, especially if the copy process performed between SD cards is interrupted due to an unexpected accident such as a power failure. This is to make it possible. This is due to the fact that the SD card is non-volatile and the data is not lost, and because there is an impact from the interruption that unnecessary data remains on the copy destination SD card, the SD card that needs to be restored stores the log file data. This is because it is considered reasonable.

  In the next processing step, the CPU starts a file duplication process corresponding to the file name written in the log file (step S105).

  After starting the replication process, the CPU checks the occurrence of interruption of the replication process, and performs processing necessary for recovery when the interruption occurs. In the processing flow, the CPU repeatedly checks the occurrence of interruption of the replication process at a predetermined timing (step S106). If it is necessary to interrupt the copying process due to an instruction from the user or the like during file copying (step S106-YES), the CPU saves the log file (file named gw_logfile.log shown in FIG. 4). The file corresponding to the described file name is deleted from the copy destination SD card (step S108). When the copying process is interrupted by an instruction from the user or the like, the data copied so far becomes meaningless data and occupies a storage area uselessly, so the CPU makes the SD card usable. Erase data in order to

  Since the file to be erased can identify each file name delimiter by using “:” as an identifier on the log file as described above, the CPU refers to the description of the log file and the file whose replication is interrupted. Are sequentially deleted, and all files written in the log file are deleted from the SD card of the copy destination.

  The CPU completes erasure of all the files in the log file in the previous stage, and when the restoration is completed (step S109-YES), the CPU also erases the log file stored in the replication destination SD card. A state where the log file is not erased means that the log file has not been restored. Therefore, the CPU deletes the log file when the recovery is completed (step S110).

  Also, when the file duplication process is completed without interruption until the end (step S107-YES), the CPU deletes the log file stored in the duplication destination SD card (step S110).

  As described above, by performing file integration processing that enables recovery from interruption of replication processing, there is no change in the storage state of the SD card before and after interruption even if it is interrupted during replication. It is possible to eliminate the waste of resources caused by creating a useless file in the destination SD card.

  In the above-described file integration process (FIG. 3), the occurrence of interruption of the duplication process is checked. However, the interruption may occur due to a reason that this check is not applied. For example, it is a case of accidental power interruption, and in such a case, the processing shown in FIG. 3 becomes impossible, and the SD card cannot be recovered immediately.

  Even in such a case, the embodiment shown below enables the recovery of the SD card in the same manner as in the above processing flow when the SD card is used thereafter.

  The SD card can be restored on the premise of creating a log file (see step S103) in the file integration process (FIG. 3) described above. Since the log file is written to the SD card, which is a non-volatile memory, the data will not be lost even if the power is turned off, and the log file is written to the SD card that needs to be restored. In this case, it is possible to perform a recovery process.

In this embodiment, an example of performing SD card recovery processing as part of device initialization processing at power-on is shown in FIG. 5. FIG. 5 shows SD card recovery processing in which unnecessary data remains due to interruption of replication processing. The processing flow of this embodiment to perform is shown. Referring to the processing flow shown in the figure, first, the CPU activates the SD card recovery processing program during the processing performed as part of the initialization of the device without an instruction from the user when the device is turned on. (Step S201).

  At the beginning of the restoration process, the CPU checks whether a log file exists in the SD cards installed in all the SD card slots (step S202). The CPU identifies whether or not the existing file is a log file by searching for a file with a special name that uses only the log file gw_logfile.log.

  If no log file is found in the card in step S202 (step S202-NO), the CPU does not need to perform any recovery processing, and the CPU exits this processing flow without doing anything.

  On the other hand, when a log file is found (step S202-YES), the CPU searches whether a file having a name described in the log file (see FIG. 4) exists in the card (step S202). (S203) If it is found, the file corresponding to the file name is deleted from the SD card (step S204). This is because the file recorded in the found log file is a file for which replication processing was interrupted once, and the meaningless data that was replicated up to the point of interruption occupies a storage area. Data erasure for recovery.

  The CPU can identify files to be deleted as individual file names by using “:” as an identifier on the log file as shown in FIG. The CPU sequentially deletes the files whose replication has been interrupted with reference to the description of the log file, and deletes all the files written in the log file from the SD card.

  The CPU completes the erasure of all the files in the log file in the previous stage, and when the restoration is completed (YES in step S205), the CPU also erases the log file stored in the SD card (step S206). The state where the log file is not erased means that the log file has not been restored. Therefore, when the restoration is completed, the CPU needs to erase the log file.

  As described above, by storing the log file in the copy destination SD card, even if the copy is interrupted in the middle, even if the user of the device does not give an instruction, the next use of the SD card is wasted. File can be erased, and file data recorded on an SD card, which is a removable storage medium, can be effectively integrated.

  The processing described with reference to FIG. 5 is based on the assumption that a log file has been created. Next, a case where a power failure occurs during log file creation will be described. The state at this time is either that a log file has not been created, or that a log file in which duplicate file information has been written partway is created.

  If the log file has not been created, the file operates normally since the file is not duplicated. If a log file with duplicate file information is created partway through, an operation to delete the file information written in the log file is executed, but the nonexistent file is not deleted, so the device Works normally.

  Next, the address book data replication will be described with reference to FIG. If the address book data is simply copied from the copy source to the copy destination, the information recorded only in the copy destination is erased, and therefore cannot be simply copied.

  First, the CPU confirms execution of SD card integration processing (step S301). That is, according to the above example, the CPU confirms the execution instruction by an operation input to the function key of the file integration process provided on the screen of the operation unit. At this time, since a plurality of SD cards are mounted, the user needs to specify an SD card to be duplicated (integrated), that is, a duplication source and a duplication destination SD card.

  When execution of the SD card integration process is instructed by the user (step S301-YES), the CPU next determines whether or not the SD card integration (duplication) process can be executed (step S302).

  Next, the CPU determines whether the file to be copied is address book data (step S303). If the file to be copied is not address book data (step S303-NO), the CPU creates a log file in which the name of the file to be copied is written (step S305) and advances the process to step S307.

  When the file to be copied is address book data (step S303-YES), the CPU searches for all file names existing in the copy destination SD card (step S304). Next, the CPU creates a log file in which the file name (X) that does not exist in the copy destination SD card and the copy target file name are written (step S306). In step S306, the CPU stores, using a flag or the like, a special replication mode indicating that the address book data is being copied. The reason why the file name is (X) is to prevent overwriting on the copy destination SD card.

  The CPU stores the log file in the replication destination SD card (step S307). Next, the CPU starts copying the file name written in the log file (step S308). The CPU determines whether the special replication mode is set (step S309). When it is not the special replication mode (step S309-NO), the CPU executes a normal replication process (step S310), and proceeds to step S319.

  In the case of the special replication mode (step S309-YES), the CPU determines whether the address book data exists (step S311). If the address book data does not exist (step S311-NO), the CPU creates a new file with the file name (X) (step S313), and advances the process to step S314.

  When the address book data exists (step S311—YES), the CPU copies the address book information of the copy destination SD card with the name of the file name (X) (step S312). That is, the CPU performs a process of creating a copy of the address book information of the copy destination SD card and setting the file name to (X).

  Then, the CPU additionally stores the address book information of the copy source SD card in the file name (X) file (step S314). When the saving is completed, the CPU describes a file name (X) file creation completion flag in the log file (step S315). The CPU copies the contents of the file name (X) file to the file with the original name of the address book data written in the log file (step S316).

  The CPU deletes the file name (X) file creation completion flag of the log file (step S317). Next, the CPU deletes the file name X file (step S318). Then, the CPU deletes the log file (step S319) and ends the process.

A description example of the log file in step S306 described above is shown below.
Slot 1: tmpFileX: AddressDataA
Here, tmpFileX is a file name that is not used in the copy destination SD card (in this case, slot 1). AddressDataA is the original file name.

A description example of the log file in step S315 is shown below.
Slot 1: tmpFileX: AddressDataA: Complete
This indicates completion of file creation.

  When the interruption occurs, only the file name (X) file is deleted in the special replication mode. However, what is described in the log file as “Complete” (see step S315) is not erased, but file information replacement processing, which is processing from step S316 to step S318, is performed.

  The method of specifying the log file by the name of the log file in the embodiment described above is merely an example, and the log file is created instead of the file name under a special directory, or the log file contents are used for identifying the log file. Even a method of embedding information can be realized if the log file name can be specified.

  Also, the log file format used “:” as an identifier here, but other symbols or line feed marks can be used as an identifier as long as the file name being described can be specified. .
