1. Field of the Invention
The disclosures herein generally relate to operation inhibiting systems, image forming apparatuses, operation inhibition information providing apparatuses, and operation inhibiting methods, and particularly relate to an operation inhibiting system, an image forming apparatus, an operation inhibition information providing apparatus, and an operation inhibiting method that inhibit users from modifying a program configuration used in the image forming apparatus.
2. Description of the Related Art
Some image forming apparatuses referred to as multifunction devices or multifunction peripherals may allow programs to be installed or uninstalled after shipment (see Japanese Patent Application Publication 2008-16013, for example). Users modify the configurations of programs installed in image forming apparatuses in accordance with needs in work, thereby attaining improvements in work efficiency.
There are programs that should not be uninstalled by users due to reasons related to proper system operations. For example, some programs may have interdependency therebetween. Uninstalling a program that is depended upon makes unusable a program that depends on the uninstalled program. Interdependency between programs may differ depending on installed program configurations. This gives rise to a complicated situation in which programs that should not be uninstalled may differ from apparatus to apparatus.
Accordingly, it may be desirable to provide an operation inhibiting system, an image forming apparatus, an operation inhibition information providing apparatus, and an operation inhibiting method that can inhibit modification to the configuration of installed programs.
It is a general object of at least one embodiment of the present invention to provide an operation inhibiting system, an operation inhibition information providing apparatus, and an operation inhibiting method that substantially eliminate one or more problems caused by the limitations and disadvantages of the related art.
In one embodiment, an operation inhibiting system includes an image forming apparatus in which programs are installed; and an operation inhibition information providing apparatus, wherein the image forming apparatus includes: a configuration information storing unit to store configuration information about the installed programs; an operation inhibition information acquiring unit to transmit the configuration information to the operation inhibition information providing apparatus, and to receive operation inhibition information that is transmitted from the operation inhibition information providing apparatus in response to the configuration information, the operation inhibition information indicating on a program-specific basis whether an operation to modify a configuration of a corresponding one of the installed programs is allowed; and an operation unit to inhibit the operation on the programs based on the received operation inhibition information, wherein the operation inhibition information providing apparatus includes an operation inhibition information providing unit that transmits the operation inhibition information responsive to the configuration information upon receiving the configuration information.
In one embodiment, an apparatus for providing operation inhibition information includes an operation inhibition information providing unit that transmits operation inhibition information responsive to configuration information upon receiving the configuration information, the operation inhibition information indicating on a program-specific basis whether an operation to modify a configuration of a program specified in the configuration information is allowed.
In one embodiment, an operation inhibiting method, which is used in an operation inhibiting system including an operation inhibition information providing apparatus and an image forming apparatus in which programs are installed, includes: transmitting, by the image forming apparatus, configuration information about the installed programs stored in a configuration information storing unit to the operation inhibition information providing apparatus; receiving, by the image forming apparatus, operation inhibition information that is transmitted from the operation inhibition information providing apparatus in response to the configuration information, the operation inhibition information indicating on a program-specific basis whether an operation to modify a configuration of a corresponding one of the installed programs is allowed; inhibiting, in the image forming apparatus, the operation on the programs based on the received operation inhibition information; and transmitting, by the operation inhibition information providing apparatus, the operation inhibition information responsive to the configuration information upon receiving the configuration information.
According to at least one embodiment, an operation to modify the configuration of an installed program is properly inhibited.
Other objects and further features of embodiments will be apparent from the following detailed description when read in conjunction with the accompanying drawings, in which:
In the following, embodiments of the present invention will be described with reference to the accompanying drawings.
The image forming apparatuses 20 may be multifunction devices that incorporate the functionality of multiple devices such as a copier, a facsimile machine, a printer, and a scanner in one device. Alternatively, the image forming apparatuses 20 may have only one function.
The operation inhibition information providing apparatus 10 is a computer that provides the image forming apparatuses 20 with information (hereinafter referred to as “operation inhibition information”) that is used to inhibit (or restrain) users from performing an operation (hereinafter referred to as “configuration modify operation”) modifying a program configuration in the image forming apparatuses 20. The image forming apparatuses 20 determine whether to allow a configuration modify operation to be performed on a program according to the operation inhibition information. Examples of the configuration modify operation include installing a program, uninstalling a program, and updating a program. Updating a program means replacing an installed old-version program with a new version of the same program. Uninstalling a program is not limited to the complete removal of an uninstalled program from the image forming apparatuses 20. The program codes may still remain in the image forming apparatuses 20 while the program is excluded from the list of usable programs.
Programs for implementing the functions of the operation inhibition information providing apparatus 10 are provided in a recording medium 101 such as a CD-ROM. Upon setting the recording medium 101 containing programs to the drive device 100, the programs are installed from the recording medium 101 to the auxiliary storage device 102 through the drive device 100. The programs do not have to be installed from the recording medium 101, and may be downloaded from another computer through a network. The auxiliary memory device 102 stores the installed programs, and, also, stores various files and data.
The memory device 103 serves to store a program read from the auxiliary storage device 102 upon a request to execute the program. The CPU 104 serves to provide the functions (illustrated in
The controller 21 includes a CPU 211, a RAM 212, a ROM 213, and an HDD 214. The ROM 213 stores therein various programs and data used by these programs, for example. The RAM 212 is used as a memory area to which programs are loaded, and is also used as a work area used by the loaded programs. The CPU 211 executes programs loaded to the RAM 212 to provide various functions. The HDD 214 stores therein programs and various types of data used by these programs, for example.
The scanner 22 is the hardware for scanning image data from a document. The printer 23 is the hardware for printing image data on a print sheet. The modem 24 is the hardware for connecting with a telephone line, and is used to exchange image data through facsimile communication. The operation panel is the hardware having an input unit such as buttons for receiving user inputs and a display unit such as a liquid crystal display panel. The network interface 26 is the hardware for connecting with a network (which may be wired or wireless). The SD-card slot 27 is used to read a program recorded in an SD card 80. In the image forming apparatus 20, not only a program stored in the ROM 213 but also a program stored in the SD card 80 is loaded to the RAM 212 for execution.
The plug-in operation unit 221 performs, in response to a user request, a configuration modify operation such as installing, uninstalling, or modifying a program package (hereinafter referred to simply as “package”) that can be added as a plug-in. Here, the term “package” refers to an archive file that stores one or more program modules, each of which is a program code for implementing a certain function. The package not only stores programs modules but also stores a file (hereinafter referred to as “package attribute file”) that store package attribute information. When a package is installed, the plug-in operation unit 221 stores the attribute information of the package attribute file of this package in the installment information storing unit 223. When a package is uninstalled, the plug-in operation unit 221 removes the attribute information of this package from the installment information storing unit 223. When a package is updated, the plug-in operation unit 221 updates the attribute information of this package stored in the installment information storing unit 223.
The installment information storing unit 223 stores therein a list of attributes (hereinafter referred to as “installment information”) with respect to the packages installed in the image forming apparatus 20 (i.e., available packages). The installment information storing unit 223 utilizes a portion of the recording area of the HDD 214 to store the installment information.
The operation inhibition information acquiring unit 222 requests the operation inhibition information providing apparatus 10 to provide operation inhibition information, and, then, receives the operation inhibition information from the operation inhibition information providing apparatus 10. The operation inhibition information acquiring unit 222 stores the acquired operation inhibition information in the operation inhibition information management unit 224. The operation inhibition information management unit 224 utilizes a portion of the recording area of the HDD 214 to store (and manage) the operation inhibition information.
The plug-in operation unit 221 determines whether to allow a configuration modify operation requested by a user to be performed, based on the operation inhibition information managed by the operation inhibition information management unit 224.
The operation inhibition information providing apparatus 10 includes an operation inhibition information providing unit 11 and an operation inhibition information storing unit 12. These units are implemented as processes performed by the CPU 104 when the CPU 104 executes the programs installed in the operation inhibition information providing apparatus 10.
In response to the request from the operation inhibition information acquiring unit 222, the operation inhibition information providing unit 11 obtains, from the operation inhibition information storing unit 12, operation inhibition information suitable for the image forming apparatus 20 that has issued the request. The operation inhibition information providing unit 11 then sends the operation inhibition information to the operation inhibition information acquiring unit 222. The operation inhibition information storing unit 12 utilizes the auxiliary storage device 102, for example, to store operation inhibition information suitable for each package on a package-specific basis with respect to the packages installed in the image forming apparatuses 20.
In the following, an operation procedure performed by the operation inhibiting system 1 will be described.
An operation request, which may be a request to install (i.e., add) a package, uninstall (i.e., remove) a package, or modify a package, is entered by a user through a screen displayed on the operation panel 25 (S101). In response to the request, the plug-in operation unit 221 checks whether the requested operation is allowed to be performed, based on the operation inhibition information stored in the operation inhibition information management unit 224 (S102).
When the configuration modify operation requested by the user is indicated as prohibited in the operation inhibition information management unit 224 (No in S102), the plug-in operation unit 221 ends the procedure of
When the configuration modify operation requested by the user is indicated as allowed or is not indicated as prohibited in the operation inhibition information management unit 224 (Yes in S102), the plug-in operation unit 221 performs the requested configuration modify operation (S103). For example, installing a package D is not prohibited in the operation inhibition information management unit 224. Upon a request to install the package D, therefore, the package D is installed.
The plug-in operation unit 221 then reflects the changes made by the configuration modify operation in the installment information storing unit 223 (S104).
The operation inhibition information acquiring unit 222 uses the installment information storing unit 223 to generate device configuration information (S105).
The operation inhibition information acquiring unit 222 transmits a request to acquire operation inhibition information to the operation inhibition information providing apparatus 10 (S106). This acquisition request includes the generated device configuration information.
The operation inhibition information providing unit 11 of the operation inhibition information providing, apparatus 10 receives the operation inhibition information acquisition request (S111). The operation inhibition information providing unit 11 then retrieves the operation inhibition information corresponding to the device configuration information included in the acquisition request from the operation inhibition information storing unit 12 (S112).
In the example illustrated in
The example of the present embodiment is directed to a case in which the operation inhibition information is retrieved from the record that specifies the device configuration information fully matching the device configuration information received from the image forming apparatus 20. When such a complete match is required, however, there may be a need to store operation inhibition information for all the package combinations (i.e., all the possible package combinations). In consideration of this, some of the packages contained in device configuration information stored in the operation inhibition information storing unit 12 may allow the use of wildcard characters. Alternatively, provision may be made such as to retrieve operation inhibition information corresponding to the device configuration information that is the closest to the received device configuration information. The term “closest” means that the extent of matches in the types of packages (which take into account version numbers) is highest. In the case of versions being different, the extent of matches may be decreased when a difference in version numbers increases.
Operation inhibition information responsive to device configuration information may be set based on interdependency between the packages contained in the device configuration information. At least a package that is depended upon by another package is set to “uninstall prohibited” (i.e., “removal prohibited”). Further, operation inhibition information may be set based on other factors in addition to interdependency. For example, a package that the maker of the image forming apparatus 20 does not wish to be uninstalled by a user for the reasons related to its business operation may be indicated as “removal prohibited”. Interdependency between packages is known to an operator who creates or edits the operation inhibition information storing unit 12. For example, the package attribute file of a given package specifies interdependency data that specifies a package name or product ID of a package on which this given package depends. The operator makes a setting to the operation inhibition information storing unit 12 based on such interdependency data. In the example illustrated in
Further, the contents of the operation inhibition information storing unit 12 may be modified in response to checking the properness of system operations of the image forming apparatus 20 or in response to a user request or the like. For example, it may turn out that a proper operation is guaranteed without the presence of a certain package. In this case, modification is made to indicate this package as removable.
The operation inhibition information providing unit 11 transmits the retrieved operation inhibition information to the operation inhibition information acquiring unit 222 of the image forming apparatus 20 (S113).
The operation inhibition information acquiring unit 222 receives the transmitted operation inhibition information (S121). The operation inhibition information acquiring unit 222 then checks whether there is a difference between the received operation inhibition information and the operation inhibition information stored in the operation inhibition information management unit 224 (S122). When there is a difference (Yes in S122), the operation inhibition information acquiring unit 222 overwrites a relevant portion of the operation inhibition information management unit 224 with the received operation inhibition information (S123). Namely, the operation inhibition information stored in the operation inhibition information management unit 224 is updated to the received operation inhibition information. When there is no difference (No in S122), the updating of the operation inhibition information management unit 224 is not performed. Alternatively, the received operation inhibition information may always be stored in the operation inhibition information management unit 224 without checking whether there is a difference. Further, the operation inhibition information providing apparatus 10 may check whether there is a difference. In this case, the operation inhibition information acquisition request includes operation inhibition information stored in the operation inhibition information management unit 224. The operation inhibition information providing unit 11 compares the received operation inhibition information with the operation inhibition information retrieved from the operation inhibition information storing unit 12 to check whether there is a difference. Upon detecting a difference, the operation inhibition information providing unit 11 transmits the operation inhibition information retrieved from the operation inhibition information storing unit 12. Upon detecting no difference, the operation inhibition information providing unit 11 transmits information indicative of no need for update.
The processes in step S105 and the subsequent steps may be performed at the time of power-on of the image forming apparatus 20. Alternatively, these processes may automatically be performed periodically. In such a case, new operation inhibition information can be promptly provided to the image forming apparatus 20 even when there is no change in the device configuration information. This happens when the maker modifies the operation inhibition information.
Further, a special operation inhibition information storing unit 12 may be provided for a specific user (i.e., a specific image forming apparatus 20). This may serve to prohibit or allow a particular operation for this user in accordance with a user request. In this case, the request to acquire operation inhibition information may specify an ID (e.g., serial number) for identifying the image forming apparatus 20. In the operation inhibition information providing apparatus 10, the operation inhibition information storing unit 12 may be linked with a specific serial number.
As described above, the operation inhibition information providing apparatus 10 manages all the operation inhibition information responsive to device configuration information in the operation inhibiting system 1 of the first embodiment. The image forming apparatus 20 acquires the operation inhibition information corresponding to device configuration information from the operation inhibition information providing apparatus 10, and, then, checks whether a configuration modify operation is allowed based on the acquired operation inhibition information. Accordingly, various configuration modify operations with respect to packages can be properly inhibited or restricted. This prevents the operating environment of the image forming apparatus 20 from being carelessly destroyed.
In the image forming apparatus 20, the operation inhibition information management unit 224 manages all the operation inhibition information corresponding to each package in an integrated manner. Accordingly, the updating of operation inhibition information can be more easily performed compared with the case in which operation inhibition information is attached to each package (i.e., contained in each package). When operation inhibition information is attached separately to each package, a change in the operation inhibition information of a given package results in the need to update this package. When operation inhibition information is managed in an integrated manner for all the packages as in the present embodiment, operation inhibition information can be updated without updating an individual package.
In the following, a second embodiment will be described. With respect to the second embodiment, a description will be given of those points which are different from the first embodiment. Other points which are not described are the same as in the first embodiment.
In
In the following, an operation procedure performed by the operation inhibiting system 2 will be described.
In
In step S112a, the operation inhibition information providing unit 11 checks whether any package contained in the received device configuration information is indicated as a package that is depended upon by another package in the interdependency storing unit 13.
The operation inhibition information providing unit 11 then generates operation inhibition information based on the results of the check of interdependency (S112b). Specifically, a package that is depended upon by another package is indicated as “removal prohibited” and “update prohibited” in the generated operation inhibition information. In the example of
The procedure that follows is the same as the one described in connection with
As described above, operation inhibition information is automatically generated based on the interdependency storing unit 13 according to the second embodiment. This lowers the need to set operation inhibition information separately for each device configuration information in advance.
Further, the present invention is not limited to these embodiments, but various variations and modifications may be made without departing from the scope of the present invention.
The present application is based on Japanese priority application No. 2009-298671 filed on Dec. 28, 2009, with the Japanese Patent Office, the entire contents of which are hereby incorporated by reference.
