Description

  The present invention relates to an electronic device that stores history information. More specifically, the present invention relates to an electronic device that stores history information of a plurality of attributes.

  2. Description of the Related Art Conventionally, image forming apparatuses configured to store history information such as a print history and an error history in a memory so that they can be viewed later have been widely put into practical use. The history information includes user information and function information (individual information such as FAX transmission / reception, PC printing, copying, and electronic mail transmission / reception), and the attribute information is also stored. The storage of history information in this way is not limited to image forming apparatuses but is common in electronic devices such as communication apparatuses and information processing apparatuses.

As an electronic device for storing such history information, for example, in Patent Document 1, an identifier corresponding to each of a plurality of lines is added and stored, and the identifier is added to a communication result report and a communication management report, respectively. Is disclosed.
JP-A-11-308394

  However, the above-described conventional electronic devices have the following problems. That is, the registration frequency of history information differs depending on the attribute of the information. If the stored history information is biased toward a specific attribute, history information other than that attribute may be lost. For example, in the case of a configuration in which one storage area for storing history information is prepared and stored without distinguishing attributes in the storage area, the oldest history information is deleted when there is no space in the storage area. It is generally performed to secure an empty space in the storage area. In such a configuration, when history information with the same attribute continues, the storage area is filled with the history information with that attribute, and history information with other attributes is erased early. In other words, history information of attributes with low registration frequency and high importance may be deleted early due to history information of attributes with low importance and high registration frequency.

  Also, a configuration in which the storage area is divided for each attribute and a dedicated storage area is assigned to each attribute is also conceivable. In this case, since the history information of the attribute having high importance is stored in the storage area dedicated to the attribute, it can be prevented that the history information is deleted early due to the history information of other attributes. However, compared to the former configuration, the storage area where each attribute can be used is relatively small, and the storage area tends to be full. For this reason, if the user concentrates on the history information of a certain attribute, the storage area for that attribute is filled up early and eventually the history information is erased early.

  The present invention has been made to solve the problems of the above-described conventional electronic devices. That is, an object of the present invention is to provide an electronic device that can prevent a storage area from being monopolized by history information with similar attributes and can retain history information with specific attributes for a long period of time.

  An electronic device made for the purpose of solving this problem includes a first storage unit that stores history information corresponding to a predetermined attribute, history information that does not correspond to the predetermined attribute, and history information transferred from the first storage unit. When the storage area of the second storage unit to be stored and the storage area of the first storage unit are equal to or less than the specified amount, at least a part of the history information stored in the first storage unit is transferred to the second storage unit. And a transition unit.

  The electronic apparatus according to the present invention includes a first storage unit that is a storage unit for a predetermined attribute and a second storage unit that is a general-purpose storage unit, and further provides a restriction amount for restricting registration in the first storage unit. It is set. The target of the “specified amount” may be, for example, the free capacity of the storage unit or the number of records of history information stored in the storage unit. The electronic device according to the present invention acquires a free space in the first storage unit when storing history information corresponding to a predetermined attribute, and stores the free space in the first storage unit when the free space is less than a specified amount. At least a part of the history information is transferred to the second storage unit. The attribute is specified by, for example, a user or a function.

  That is, the electronic device of the present invention provides a first storage unit for specific attributes and a general-purpose second storage unit, so that even if history information of attributes other than the predetermined attribute is continuous, those history information Is stored in the second storage unit, and history information of a predetermined attribute is held in the first storage unit. Thus, early deletion of history information with a predetermined attribute is avoided. Further, when the first storage unit is almost full, at least a part of the history information stored in the first storage unit is moved to the second storage unit. That is, the second storage unit is used as a spare storage location. As a result, even if the first storage unit becomes full at an early stage, the stored information is not immediately erased. Therefore, history information with a predetermined attribute can be retained for a long time.

  Moreover, the transfer part of the electronic device of this invention makes the oldest log | history information of the log | history information memorize | stored in the 1st memory | storage part the object of transfer to a 2nd memory | storage part. In other words, if you move with superiority or inferiority based on time-series order, it is easy to maintain fairness and ease of use.

  Further, it is better that the migration unit of the electronic device of the present invention deletes a part of the history information items to be migrated when the history information is migrated to the second storage unit. That is, the history information to be transferred tends to be less important even in the history information. Thus, by deleting a part of the information and storing it in the second storage unit, the burden on the second storage unit can be reduced. Further, the second storage unit can store more information including the history information to be transferred.

  In the electronic device of the present invention, it is better that the first storage unit is configured by a nonvolatile memory and the second storage unit is configured by a volatile memory. That is, the present invention has a configuration in which history information with high importance is stored in the first storage unit, and history information stored in the second storage unit is less important than the first storage unit. Therefore, memory resources can be effectively used by configuring the second storage unit with a volatile memory.

  The first storage unit of the electronic device of the present invention preferably has a plurality of attributes that can be stored, and a storage area is allocated for each attribute. That is, the management target can be subdivided and more appropriate history management can be performed.

  In addition, when the history information of the attributes that can be stored in the first storage unit is stored in the first electronic device, if there is no storage area corresponding to the attribute, an allocation to newly allocate a storage area for the attribute is performed. It is better to have a section. That is, memory resources can be used effectively by allocating storage areas as necessary. In addition, it is possible to deal with attributes added later, and flexible operation becomes possible.

  In addition, the electronic device of the present invention is preferably provided with a setting unit that sets a prescribed amount that serves as a threshold for the migration unit to migrate history information. That is, the convenience for the user is improved by enabling the specified amount to be set.

  In addition, the electronic device of the present invention preferably includes a selection unit that selects an attribute of history information to be stored in the first storage unit. That is, the user can select history information to be retained for a long time. This improves user convenience.

  According to the present invention, it is possible to realize an electronic device that can avoid the storage area from being monopolized by history information with similar attributes and can retain history information with specific attributes for a long period of time.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of a printing apparatus according to the invention will be described in detail with reference to the accompanying drawings. The present invention is applied to a multi function peripheral (MFP) that handles print jobs having various attributes such as copying, PC printing that is a print performed in response to an instruction from a PC, and FAX printing that is a print that has been received by FAX. Is applied.

[Overall configuration of MFP]
As shown in FIG. 1, MFP 100 according to the embodiment includes an image forming unit 10 that prints an image on a sheet, and an image reading unit 20 that reads an image of a document. Further, on the front side of the image reading unit 20, an operation panel 40 including a display unit 41 formed of a liquid crystal display and a button group 42 including a start key, a stop key, a numeric keypad, and the like is provided. 40 enables operation status display and user input operation.

  The image forming unit 10 forms an image based on image data sent from an information terminal device such as a personal computer (PC) or image data of a document read by the image reading unit 20, and prints the image on paper. . The image forming method may be an electrophotographic method or an ink jet method. Further, it may correspond to a color image or may be dedicated to a monochrome image. The MFP 100 of this embodiment is an electrophotographic color image forming apparatus.

  The image reading unit 20 reads the image of the document set on the document table and creates image data of the document. In addition, the image reading unit 20 includes an ADF (Auto Document Feeder) that automatically conveys a document at a position that is the top of the MFP 100, and can continuously read a plurality of documents.

  The MFP 100 has a function of handling print jobs having various attributes such as copying, PC printing, and FAX printing. These print jobs are asynchronously sent to the MFP 100 when the user operates the operation panel 40, from an information processing apparatus such as a PC via a network, or from a partner FAX apparatus via a communication line. The MFP 100 prints the received print job in a predetermined order. Print information at the time of print processing and error information when an error occurs are stored in the memory as history information. Details of the history information storing process will be described later.

[Electric configuration of MFP]
Next, the electrical configuration of the MFP 100 will be described. As illustrated in FIG. 2, the MFP 100 includes a control unit 30 including a CPU 31, a ROM 32, a RAM 33, an NVRAM 34, an ASIC 35, a network interface 36, and a FAX interface 37. The ASIC 35 of the control unit 30 is electrically connected to the image forming unit 10, the image reading unit 20, the operation panel 40, and the like.

  The CPU 31 executes arithmetic operations for realizing various functions such as an image reading function and an image forming function in the MFP 100, and is the center of control. The ROM 32 stores various control programs for controlling the MFP 100, various settings, initial values, and the like. The RAM 33 is used as a work area from which various control programs are read or as a storage area for temporarily storing image data. An NVRAM (Non Volatile RAM) 34 is a non-volatile storage means and is used as a storage area for storing various settings or image data.

  The CPU 31 stores each processing result in the RAM 33 or the NVRAM 34 in accordance with a control program read from the ROM 32 and signals sent from various sensors, and turns on each component of the MFP 100 (for example, lighting timing of the exposure apparatus constituting the image forming unit 10). , A driving motor (not shown) for various rollers constituting the paper conveyance path, and a moving motor (not shown) for the image sensor unit constituting the image reading unit 20 are controlled.

  The network interface 36 is connected to a network such as the Internet, and enables connection with an information processing apparatus such as a PC. The FAX interface 37 is connected to a telephone line and enables connection with a destination FAX apparatus. Jobs can be exchanged via the network interface 36 or the FAX interface 37.

[History information management]
Next, the history information management function of the MFP 100 will be described. When the MFP 100 performs the printing process, the MFP 100 stores the printing information and the like in the memory area as history information. The importance of history information varies depending on the attribute. For example, the history information of the FAX print includes information on the transmission source and the transfer source, and is considered to be more important than copying and PC printing. The MFP 100 also has a login function that restricts the printing function for each user, and may manage the print history of each logged-in user. Therefore, MFP 100 stores the history information by distinguishing the attribute.

  Specifically, as shown in FIG. 3, a memory area for storing history information of MFP 100 is a dedicated history area 60 for storing history information of a specific attribute, and a general history for storing history information without distinguishing attributes. An area 63 (an example of a second storage unit) is provided. If the history information can be stored in the dedicated history area 60, the MFP 100 stores the history information in the dedicated history area 60, and stores other history information in the general history area 63.

  The dedicated history area 60 includes a FAX storage area 61 (an example of a first storage unit) for storing FAX print history information, and a user individual storage area 62 (for storing user history information registered in advance). An example of the first storage unit). Since MFP 100 has a login function, a user name for login is registered. A user registered in advance is a user who can log in to MFP 100. In the user individual storage area 62, a storage area is secured for each registered user. For example, when users A, B, and C are registered in MFP 100, as shown in FIG. 3, storage area 621 for user A, storage area 622 for user B, and storage for user C Area 623 is secured.

  In each of the storage areas 61, 621, 622, and 623 constituting the dedicated history area 60, a limit value (an example of a specified amount) that defines the number of records that can be stored is set for each storage area. The limit value is managed by a limit value table 55 as shown in FIG. In this embodiment, the limit value for FAX printing is set to 30, and the limit values for users A, B, and C are set to 10. This limit value is an example and is not limited to this. For example, if the user A is an administrator, the limit value may be set larger than those of the users B and C who are general users. As a limit value, a common limit value may be provided for all attributes, but processing priority is often different for each job attribute. Therefore, by setting limit values for each job attribute, more appropriate operation can be achieved.

  The contents of history information vary depending on attributes. For example, as shown in FIG. 5, the FAX print history information stored in the FAX storage area 61 includes a job identification name, basic print information, and FAX print unique information. The basic print information is basic information of print processing and includes, for example, resolution, selection tray, paper size, multi-page setting, duplex printing setting, number of copies, monochrome / color setting. The FAX print unique information is information unique to the FAX print, and includes, for example, a transmission source telephone number, a printing time, and a transfer source ID. The print history information stored in the user individual storage area 62 includes a job identification name, basic print information, and user specific information. The basic print information has the same configuration as the basic print information for FAX printing. The user specific information includes, for example, a user name, printing time, and remaining print permission number.

  The history information is basically stored in a history area corresponding to the attribute of the history information. That is, FAX print history information is stored in the FAX storage area 61, print history information registered by the MFP 100 by the user is stored in the user individual storage area 62, and other attribute history information is , Stored in the general history area 63. However, there are exceptions in the following cases.

  That is, since limit values are set in the FAX storage area 61 and the user individual storage area 62, more history information than the limit value cannot be stored. Therefore, when the number of records in the history information exceeds the limit value, the oldest history information stored in the storage area (hereinafter referred to as “oldest history information”) is the general history area 63. Moved to.

  The memory area of the MFP 100 includes a RAM 33 and an NVRAM 34. The dedicated history area 60 is secured in the NVRAM 34. That is, the history information stored in the dedicated history area 60 tends to be highly important. Therefore, history information is stored in a non-volatile memory area and retained for a long time. On the other hand, history information having a low importance tends to be stored in the general history area 63. Therefore, the RAM 33 which is a volatile memory is used. By determining the storage medium according to the attribute of the history information, the use of the NVRAM 34, which has a large load related to cost per unit storage amount and labor, can be suppressed, and the capacity thereof can be kept low.

  FIG. 6 shows an example of storing FAX print history information, and an example of transferring history information from the FAX storage area 61 to the general-purpose history area 63. The example in FIG. 6 focuses on FAX printing and omits examples of other attributes. Further, it is assumed that history information is stored in the order of numbers attached to the characters “FAX” in FIG.

  First, FIG. 6A shows a state in which 29 pieces of history information are already stored in the FAX storage area 61. On the other hand, it is assumed that no history information of FAX printing is stored in the general history area 63. Since the FAX storage area 61 is used as a storage area dedicated to FAX printing, history information of attributes other than FAX printing is not stored. Therefore, even if history information with attributes other than FAX printing occurs, the FAX storage area 61 is not affected.

  Next, in the state of FIG. 6A, when a FAX 30 that is new history information of FAX printing occurs, the FAX 30 is stored in the FAX storage area 61 as shown in FIG. 6B. As a result, the number of records in the FAX storage area 61 reaches the limit value, and the FAX storage area 61 becomes full.

  Next, when the FAX 31 that is new history information is generated in the state of FIG. 6B, since the same number of history information as the limit value is already stored in the FAX storage area 61, the FAX storage area. 61 cannot be stored. Therefore, as shown in FIG. 6C, FAX 1 which is the oldest history information in the FAX storage area 61 is moved to the general history area 63. Then, the FAX 31 that is new history information is stored in the FAX storage area 61. Thereby, the FAX storage area 61 always stores a maximum of 30 new history information. Also, the old history information is not immediately deleted, but is secured (as the latest) at the head of the general history area 63.

  Note that there is a limit to the history information that can be stored in the general history area 63 as well. For example, when the physical capacity of the RAM 33 is stored up to the full capacity, or when the limit value is provided in the general history area 63 as well. In that case, the oldest history information in the general history area 63 is deleted, and new history information is stored.

[History storage processing]
Next, a procedure of MFP 100 that realizes the above-described history management function will be described. First, a history storage process for storing history information generated when a print job is completed in various history areas will be described with reference to the flowchart of FIG. This process is executed every time MFP 100 ends a print job and history information associated with the print process is generated.

  First, it is determined whether or not the attribute of the history information is FAX printing (S101). That is, history information whose attribute is FAX print is extracted with priority over other attributes. In the case of FAX printing (S101: YES), FAX storage processing for storing the history information in the FAX storage area 61 is performed (S121).

  Here, the FAX storage process (an example of the transfer unit) in S121 will be described with reference to the flowchart of FIG. First, the number of history information items stored in the FAX storage area 61 is acquired (S201). Then, it is determined whether or not the acquired number is smaller than the limit value, that is, whether or not it can be stored in the FAX storage area 61 (S202). If it can be stored in the FAX storage area 61 (S202: YES), the history information is stored in the FAX storage area 61 (S203).

  On the other hand, if the data cannot be stored in the FAX storage area 61 (S202: NO), the oldest history information in the FAX storage area 61 is extracted (S211). Then, the FAX print unique information is deleted from the oldest history information (S212). Then, the oldest history information from which the FAX print unique information has been deleted is stored at the head of the general history area 63 (S213), and the oldest history information is deleted from the FAX storage area 61 (S214). That is, the oldest history information is transferred to the general-purpose history area 63. The history information to be migrated is the oldest history information, and its utility value tends to be lower than new history information. Therefore, the FAX print unique information is deleted to reduce the data size. As a result, the burden on the general-purpose history area 63 that is the migration destination is small.

  By deleting the oldest history information, the FAX storage area 61 is vacant. Therefore, the latest FAX print history information is stored in the FAX storage area 61 (S203). As a result, the latest history information is always stored in the FAX storage area 61.

  Returning to the flowchart of FIG. 7, if the attribute of the history information is not FAX printing (S101: NO), it is next determined whether or not the attribute is an individual print by the user registered in the MFP 100 (S102). ). If it is an individual print of the corresponding user (S102: YES), an individual user storage process for storing history information in the individual user storage area 62 is performed (S131).

  Here, the individual user storage process (an example of the migration unit and the allocation unit) in S131 will be described with reference to the flowchart of FIG. First, it is determined whether or not the user individual storage area 62 has a storage area for the user who has performed the printing process (S301).

  If there is no storage area for the user who has performed the printing process (S301: NO), the history information cannot be stored in the user individual storage area 62. Therefore, it is determined whether or not a storage area for the user who has performed the printing process can be created (S311). That is, it is determined whether or not a new storage area can be physically secured in the user individual storage area 62, or whether or not there is a restriction regarding storage area creation (for example, a restriction that a user who is not logged in does not hold the storage area).

  If a new storage area can be created (S311: YES), a new storage area for the user is created (S312). Default limits are set in newly created storage areas. After creating the storage area, the process proceeds to S302. On the other hand, if a new storage area cannot be created (S311: NO), the history information is stored in the general history area 63 (S313).

  On the other hand, when there is a storage area for the user who has performed the printing process (S301: YES), or when a new storage area is created in the process of S312, the number of history information stored in the storage area of the corresponding user Is acquired (S302). Then, it is determined whether or not the acquired number of records is smaller than the limit value corresponding to the corresponding user, that is, whether or not it can be stored in the storage area of the corresponding user (S303). If it can be stored in the storage area of the corresponding user (S303: YES), the history information is stored in the storage area (S304).

  On the other hand, if it cannot be stored in the storage area of the corresponding user (S303: NO), the oldest history information in the storage area is extracted (S321). Then, the extracted oldest history information is stored (as the latest) in the head of the general history area 63 (S322), and the oldest history information is deleted from the storage area (S323).

  By deleting the oldest history information, the corresponding user's storage area is made free. Therefore, the latest history information is stored in the storage area of the corresponding user (S304). Thereby, the history information stored in the storage area of the corresponding user is always the latest history information.

  In the above example, all the history information stored in the storage area is the target to be transferred to the general history area 63, but an exception may be provided. For example, history information after performing so-called secure printing tends to be more important than normal printing, and it is not preferable to be subject to automatic erasure. Therefore, the history information after secure printing may be excluded from the history information to be transferred to the general history area 63. In addition, if all history information after secure printing is excluded from movement, all history information in the storage area may become history information after secure printing. Therefore, only the latest history information after secure printing may be excluded from the movement target.

  Returning to the flowchart of FIG. 7, if the print is not an individual print by the user registered in the MFP 100 (S102: NO), the history information is stored in the general history area 63 (S103). Thus, the history information is distributed and stored in any history area.

[User registration process]
Next, user registration processing (an example of a setting unit and a selection unit) for performing user registration in the MFP 100 will be described with reference to the flowchart of FIG. This process is a process in which a user with the administrator attribute arbitrarily performs user registration, and is executed when a new registration instruction is input by the user with the administrator attribute.

  First, a screen for inputting a user name of a newly registered user is displayed (S401). For example, a user name input screen as shown in FIG. When an instruction to end the input of the user name is given, a new user is registered with the input user name (S402).

  Next, a screen for inquiring whether or not to create a newly registered user storage area in the user individual storage area 62 is displayed (S403). For example, a storage area creation selection screen as shown in FIG. When the new creation of the storage area is not selected (S404: NO), the process after S405 is bypassed and this process is terminated.

  When the creation of a new storage area is selected (S404: YES), a screen for setting the number of records that can be stored in the storage area, that is, a limit value is displayed (S405). For example, a limit value setting screen as shown in FIG. When the input of the limit value is instructed, a storage area capable of storing a set number of records is secured in the user individual storage area 62 (S406). Thereby, the new registration of the user to the MFP 100 is completed.

  As described above in detail, the MFP 100 according to the present embodiment includes a dedicated history area 60 that is a storage unit for specific attributes and a general-purpose history area 63 that is a general-purpose storage unit in the memory area. For this reason, even if history information of attributes other than the predetermined attribute (in this embodiment, FAX print or registered user) stored in the dedicated history area 60 continues, the history information is stored in the general history area 63. , History information of a predetermined attribute is held in the dedicated history area 60. Therefore, early deletion of the history information with a predetermined attribute is avoided. If the FAX storage area 61 or the user individual storage area 62 constituting the dedicated history area 60 is almost full, at least a part of the history information stored in the nearly full storage area is used as the general history area 63. Move to. That is, the general history area 63 is used as a spare storage location. As a result, even if the FAX storage area 61 or the user individual storage area 62 is filled up at an early stage, the information stored in them is not immediately erased. Therefore, history information with a predetermined attribute can be retained for a long time.

  In addition, when the registered user storage area is not secured, the MFP 100 newly allocates a storage area for the user. That is, by allocating storage areas as necessary, it is not necessary to secure storage areas for all registered users from the beginning, and memory resources can be used effectively. In addition, it is possible to deal with users added later, and flexible operation becomes possible.

  Note that this embodiment is merely an example, and does not limit the present invention. Therefore, the present invention can naturally be improved and modified in various ways without departing from the gist thereof. For example, not only MFPs but also image processing apparatuses such as copiers, scanners, and fax machines, and further, not only image processing apparatuses but also electronic devices such as PCs and mobile phones that handle history information If so, it is applicable.

  In the embodiment, the present invention is applied to the case where print job history information is stored. However, the history information is not limited to print jobs. For example, history information of a transmission job such as FAX transmission or E-mail transmission may be stored.

  In the embodiment, a limit value for the number of registrations is set in each storage area of the dedicated history area 60 as a threshold value for determining whether registration is possible, but the threshold value is not limited to the number of registrations. For example, a limit capacity of the total data size may be set for each storage area, that is, for each attribute.

  Further, in the embodiment, when the registered user storage area is not secured, the MFP 100 itself determines whether or not a new storage area can be created, and automatically secures a new storage area. However, it is not limited to this. That is, the user may be inquired whether to create a storage area.

  In the embodiment, when the data cannot be stored in the FAX storage area 61, a part of the information is moved to the general history area 63. However, all information may be moved. Further, when moving to the general history area 63, the history information is moved one record at a time, but a plurality of records may be moved together.

  Further, in the embodiment, when storage to the storage area of the dedicated history area 60 is impossible, the oldest history information is moved to the general history area 63 regardless of the storage area of any attribute. It is not limited to. That is, the history information with low importance may be configured to be deleted in order from the oldest history information without moving the history information to the general-purpose history area 63. For example, the history information of the administrator user in the user individual storage area 62 may be moved, but the history information of other users may be deleted.

  In addition to print information and communication information, for example, image data may be stored as history information. In other words, since MFP 100 can hold history information for each user, for example, when it has a reprint function for re-execution of print processing, the latest print information and image data are stored for each user. Thus, reprint for each user can be realized. That is, the image data of the user is not erased by another user's print, so that the user can re-execute the print processing. In this case, when moving to the general history area 63, the image data may be deleted and moved in order to make the data size compact.
