The present application claims priority under 35 U.S.C. § 119 to Japanese Patent Application No. 2016-250773 filed on Dec. 26, 2016 and Japanese Patent Application No. 2017-230718 filed on Nov. 30, 2017, the entire contents of which are incorporated herein by reference.
The present invention relates to an input/output device and an information processing system.
Services that enable cooperation between a document input/output device, such as a multifunction peripheral (MFP), and a computer system that provides an external storage service offering a storage area via a network are known (such services being referred to as “device cooperation services” hereinafter). A “scan to storage service” is an example of such a device cooperation service for delivering scanned image data acquired by an MFP application to a preset external storage service.
Also, image formation restriction control systems are known that are configured to properly restrict use of each image forming apparatus connected to a network, for example. A typical image formation restriction control system restricts use of an image forming apparatus by a user when a total sum of the number of sheets used over a predetermined time period exceeds a use limit (maximum number of sheets) set up for the user, and notifies the user that a use restriction has been imposed according to a predetermined notification method (see, e.g., Japanese Unexamined Patent Publication No. 2008-152499).
An administrator typically imposes restrictions on a user's ability to designate scan conditions of a device cooperation service in order to have the user conform to rules relating to scan operations. However, restrictions on the designation of scan conditions that are set up in typical device cooperation services restrict designation of conditions in a scan job for an input/output device. Thus, such restrictions on the designation of scan conditions cannot restrict designation of conditions in a request to an input/output service from the input/output device.
An aspect of the present invention is directed to enabling an input/output device that provides a device cooperation service to restrict designation of a condition in a request to an input/output service.
According to one embodiment of the present invention, an input/output device that provides a device cooperation service is connected to an input/output service apparatus that provides an input/output service and a computer system that provides a storage service via a network. The input/output device includes a processor configured to execute a program stored in a memory to implement processes of acquiring use restriction information for restricting designation of a condition in a request to the input/output service from the input/output device, and restricting designation of the condition in the request to the input/output service from the input/output device by reflecting the acquired use restriction information on a device cooperation service screen for enabling a user to designate the condition in the request.
In the following, embodiments of the present invention are described with reference to the accompanying drawings.

<Functional Configuration>
In the following, the functional configuration of the information processing system 1 according to the present embodiment will be described.
<<Input/Output Service Apparatus>>
Note that in
The input/output service apparatus 10 according to the present embodiment includes an input/output service process unit 110, a web service process unit 120, a document service unit 130, and an external service cooperation unit 140. Each of the above units may be implemented by the CPU 506 executing a process based on one or more programs installed in the input/output service apparatus 10.
The input/output service apparatus 10 according to the present embodiment also includes an app information storage unit 150. The app information storage unit 150 may be implemented by the HDD 508, for example. Note that the app information storage unit 150 may also be implemented by a storage device that is connected to the input/output service apparatus 10 via a network, for example.
The input/output service process unit 110 performs processes associated with the input/output service. In
The app management unit 111 manages app information 1000 stored in the app information storage unit 150. The app information 1000 includes information relating to applications (apps) for enabling the input/output service device 10 to provide various input/output services. That is, the various input/output services provided by the input/output service apparatus 10 are provided by the app information 1000.
Also, in response to receiving a request from the logic process unit 112, the app management unit 111 sends process flow information 1100 included in the app information 1000 to the logic process unit 112. The process flow information 1100 defines a series of processes (process flow) for implementing the input/output service provided by the app information 1000. For example, the process flow information 1100 may define a series of processes (process flow) that includes performing an OCR process on scanned image data that has been acquired by the MFP 20 and delivering the processed image data to a preset external storage system 30.
The logic process unit 112 acquires the process flow information 1100 from the app management unit 111 in response to a request from the web service process unit 120. Based on the acquired processing flow information 1100, the logic process unit 112 executes a process flow for implementing the input/output service. In this way, various input/output services can be provided by the input/output service apparatus 10 of the information processing system 1 according to the present embodiment.
The data I/F unit 113 makes various requests to the data processing unit 142 of the external service cooperation unit 140 in response to a request from the web service processing unit 120. For example, the data I/F unit 113 may issue a folder list acquisition request to the data processing unit 142 of the external service cooperation unit 140.
The web service processing unit 120 makes various requests to the input/output service process unit 110 in response to a request from the browser 210. For example, the web service process unit 120 may issue a scan delivery service process execution request to the logic process unit 112 of the input/output service process unit 110 in response to a request from the browser 210.
The document service unit 130 is implemented by a group of programs (modules) for executing processes included in a series of processes (process flow) defined by the process flow information 1100. The document service unit 130 includes a PDF conversion unit 131 for converting the data format of an electronic file into the PDF format as an example.
Note that the document service unit 130 may include various programs, such as a print conversion unit for converting an electronic file into a data format (print data) that can be printed by the MFP 20 and/or a compression/decompression process unit for compressing or decompressing an electronic file, for example.
The external service cooperation unit 140 makes various requests to the external storage system 30 in response to requests from the logic process unit 112 and the data I/F unit 113. The input/output service apparatus 10 according to the present embodiment includes a corresponding external service cooperation unit 140 for each external storage system 30.
The external service cooperation unit 140 includes a file process unit 141 that receives a request from the logic processing unit 112, and a data process unit 142 that receives a request from the data I/F unit 113.
The file process unit 141 includes a common I/F 1411 and a unique I/F 1412 that define APIs (Application Programming Interfaces) for performing operations with respect to an electronic file stored in the external storage system 30. The operations to be performed with respect to an electronic file may include acquisition, storage, and editing of the electronic file, for example.
The common I/F 1411 defines APIs that can be commonly used among a plurality of external storage systems 30. That is, the common I/F 1411 of the file process unit 141 corresponds to a group of APIs for implementing functions related to file operations (e.g., acquisition and storage of electronic file) that can be used by all the external storage systems 30.
On the other hand, the unique I/F 1412 defines APIs that can be used by a specific external storage system 30. That is, the unique I/F 1412 of the file process unit 141 corresponds to a group of APIs for implementing functions related to file operations (e.g., editing of electronic file) that can be used by a specific external storage system 30.
Thus, the common I/F 1411 is similarly defined for all the external service cooperation units 140. On the other hand, the unique I/F 1412 is uniquely defined for the corresponding external service cooperation unit 140 associated with the specific external storage system 30 that is able to use the API included in the unique I/F 1412.
The data process unit 142 includes a common I/F 1421 and a unique I/F 1422 that define APIs for acquiring metadata such as bibliographic information (e.g., file list, folder list) of an electronic file stored in the external storage system 30.
The common I/F 1421 defines APIs that can be commonly used among a plurality of external storage systems 30. That is, the common I/F 1421 of the data process unit 142 corresponds to a group of APIs for implementing functions such as metadata acquisition (e.g., acquisition of a file list or folder list) that can be used by all the external storage systems 30.
On the other hand, the unique I/F 1422 defines APIs that can be used by a specific external storage system 30. That is, the unique interface 1422 of the data process unit 142 corresponds to a group of APIs for implementing functions such as metadata acquisition (e.g., acquisition of an image file list) that can be used by a specific external storage system 30.
Thus, the common I/F 1421 is similarly defined for all the external service cooperation units 140. On the other hand, the unique I/F 1422 is uniquely defined for the corresponding external service cooperation unit 140 associated with the specific external storage system 30 that is able to use the API included in the unique I/F 1422.
Note that when an external storage system 30 with which the input/output service apparatus 10 can cooperate (hereinafter referred to as “cooperation counterpart”) is added or deleted, a corresponding external service cooperation unit 140 for the external storage system 30 may added or deleted, for example.
The input/output service apparatus 10 according to the present embodiment is capable of localizing the impact of adding an external storage system 30 as a cooperation counterpart. In other words, the input/output service apparatus 10 according to the present embodiment is capable of adding an external storage system 30 as a cooperation counterpart without affecting other functional components (e.g., input/output service process unit 110, web service process unit 120), for example. Note that the input/output service apparatus 10 according to the present embodiment may add a corresponding external service cooperation unit 140 using a SDK (Software Development Kit), for example.
The app information storage unit 150 stores the app information 1000 in association with an app ID of an application for providing an input/output service (referred to as “app ID” to be distinguished from an application ID of an MFP application), for example. The app information 1000 includes one or more sets of process flow information 1100. As described above, the process flow information 1100 is information that defines a series of processes (process flow) for implementing an input/output service provided by the app information 1000.
<<MFP>>
For example, each of the above functional units of
The operation accepting unit 220 accepts a user operation, such as selection of a delivery destination folder, change of a scan condition, or a job execution instruction, for example. The screen rendering unit 222 renders a screen of an MFP application for implementing a device cooperation service (device cooperation service screen) on the operation panel 602. The scan execution unit 224 sends a scan execution request to the scanner 606 and causes the scanner 606 to execute a scan process. The upload request unit 226 sends an upload request to the input/output service apparatus 10 to have scanned image data uploaded to the external storage system 30.
The application acquisition unit 228 acquires an MFP application from the content providing service apparatus 14. The content providing service apparatus 14 provides the MFP application, which may be described in HTML, CSS, and JavaScript, for example, to the MFP 20. The application execution unit 230 executes the MFP application.
The use restriction information acquisition unit 232 acquires use restriction information from the use restriction information generating service apparatus 12. The use restriction unit 240 interprets the acquired use restriction information and reflects the use restriction information on the device cooperation service screen of the MFP application by disabling a change to a value of a setting item on which a use restriction is imposed, for example.
The delivery destination list acquisition unit 234 acquires a folder list from the external storage system 30 in order to display a list of folders of the external storage system 30 corresponding to delivery destination candidates. The request data generation unit 236 generates request data (upload condition) to be sent to the input/output service apparatus 10. The setting reflection unit 238 controls settings to reflect a delivery destination folder and scan conditions selected by the user, for example.
<<Use Restriction Information Generating Service Apparatus>>
The use restriction information generating service apparatus 12 according to the present embodiment also includes a user information storage unit 258 and a use restriction information storage unit 260. The user information storage unit 258 and the use restriction information storage unit 260 may be implemented by the HDD 508, for example. The user information storage unit 258 and the use restriction information storage unit 260 may also be implemented by a storage device that is connected to the use restriction information generating service apparatus 12 via a network, for example.
The login process unit 250 receives a login request from an external apparatus, such as the PC 22, and performs a login process using the user information stored in the user information storage unit 258. Upon successful login, the login process unit 250 allows the PC 22 access to services provided by the use restriction information generating service apparatus 12. When the use restriction setting screen providing unit 252 receives a use restriction setting screen display request designating an application ID from the PC 22, the use restriction setting screen providing unit 252 uses the use restriction information stored in the use restriction information storage unit 260 to provide use restriction setting screen data relating to a device cooperation service associated with the designated application ID to the PC 22.
The use restriction information registration accepting unit 254 accepts a registration request for registering use restriction information from the PC 22 and registers the use restriction information in association with an application ID in the use restriction information storage unit 260. When the use restriction information providing unit 256 receives a use restriction information acquisition request designating an application ID from the MFP 20, the use restriction information providing unit 256 provides the use restriction information that is stored in association with the designated application ID in the use restriction information storage unit 260 to the MFP 20.
<Detailed Process Operations>
In the following, detailed process operations of the information processing system 1 according to the present embodiment will be described.
<<Registration Phase>>
Note that although the administrator is depicted as directly operating the use restriction information generating service apparatus 12 to register use restriction information in
In step S11, the administrator designates an administrator ID and a password and issues a login request to the use restriction information generating service apparatus 12. The login process unit 250 of the use restriction information generating service apparatus 12 accepts the login request from the PC 22 and performs a login process using the user information stored in the user information storage unit 258. Upon successful login, the login process unit 250 of the use restriction information generating service apparatus 12 allows the PC 22 to use services provided by the use restriction information generating service apparatus 12.
Then, in step S12, the PC 22 designates an application ID corresponding to a device cooperation service selected by the administrator in a use restriction setting screen display request and sends the use restriction setting screen display request to the use restriction information generating service apparatus 12. In the example described below, it is assumed that an application ID corresponding to the device cooperation service “scan to storage service” is designated in the use restriction setting screen display request. When the use restriction setting screen providing unit 252 of the use restriction information generating service apparatus 12 receives the use restriction setting screen display request from the PC 22, the use restriction setting screen providing unit 252 causes the PC 22 to display a use restriction setting screen 2000 as illustrated in
The use restriction setting screen 2000 also includes scan condition setting fields 2006 for designating initial values of scan conditions and whether the scan conditions can be changed, and upload condition setting fields 2008 for designating initial values of upload conditions and whether the values of the upload conditions can be changed. For example, in
When a save button 2014 in the use restriction setting screen 2000 in
The “app ID” is information identifying specific app information 1000 stored in the app information storage unit 150 for identifying an application for implementing an input/output service provided by the app information storage unit 150. The “flow ID” is information identifying specific process flow information 1100 included in the app information 1000 for identifying a series of processes (process flow) for implementing an input/output service provided by the app information storage unit 150.
Note that in the example use restriction information illustrated in

The example use restriction information of
Also, the example use restriction information of
Note that the use restriction information is output in JSON format. After the use restriction information is registered in step S14, the process proceeds to step S15 in which the use restriction information generating service apparatus 12 returns the registered use restriction information to the PC 22. In this way, the administrator can easily register use restriction information via the use restriction setting screen 2000 as illustrated in
Note that in some embodiments, after step S15, the information processing system 1 may implement a function of verifying whether the use restriction information registered in step S14 can be implemented by the MFP application, for example. The MFP application can interpret the use restriction information acquired from the use restriction information generating service apparatus 12 and reflect the use restriction information on the device cooperation service screen of the MFP application by displaying a relevant upload condition setting item subjected to use restriction in a change-disabled state such that its value cannot be changed from its initial value.
<<Use Phase>>
In step S21, the user operates the MFP 20 to designate one MFP application from an MFP application list and make a display request to have a device cooperation service screen of the designated MFP application displayed, for example.
In step S22, the application acquisition unit 228 of the MFP 20 acquires HTML data of the MFP application designated by the user from the content providing service apparatus 14. In step S23, the application acquisition unit 228 acquires CSS data and JavaScript data of the MFP application designated by the user from the content providing service apparatus 14.
By executing the acquired CSS data and JavaScript data of the MFP application, the MFP 20 may be able to use the use restriction information acquisition unit 232, the delivery destination list acquisition unit 234, the request data generation unit 236, the setting reflection unit 238, and the use restriction unit 240.
Then, in step S24, the use restriction information acquisition unit 232 of the MFP 20 acquires use restriction information registered in association with the designated MFP application from the use restriction information generating service apparatus 12 by designating identification information (e.g., application ID) that is capable of uniquely identifying the relevant use restriction information as described above with reference to
Then, in step S25, the application execution unit 230 causes the screen rendering unit 222 to generate the device cooperation service screen of the MFP application. Note that the screen rendering unit 222 generates the device cooperation service screen of the MFP application based on the initial display screen specified in the common settings set up via the use restriction setting screen as illustrated in
Then, in step S27, the delivery destination list acquisition unit 234 designates a root folder ID and sends a folder list acquisition request to the external storage system 30 to acquire a folder list. Note that in step S28, the screen rendering unit 222 of the MFP 20 displays the device cooperation service screen of the MFP application when generation of the device cooperation service screen is completed.
In step S29, the MFP 20 acquires the folder list from the external storage system 30. The screen rendering unit 222 of the MFP 20 displays the folder list acquired from the external storage system 30 in a folder selection screen as illustrated in
When a “Select Delivery Destination” button displayed in the folder selection screen is pressed, the screen of the MFP 20 transitions from the folder selection screen to a job setting screen as illustrated in
When a certain job setting item is selected from the job setting screen, the MFP 20 displays a job setting selection screen as illustrated in FIG. 10. The job setting selection screen is a screen for accepting a job setting change from the user. The job setting selection screen of
Further, start buttons are included in the job setting screen and the job setting selection screen of
Referring back to
Then, in step S33, the user presses the start button and requests the MFP 20 to start a scan process. The scan execution unit 224 of the MFP 20 causes the scanner 606 to perform scan operations. In step S34, the request data generation unit 236 of the MFP 20 generates request data to be sent to the input/output service apparatus 10 including an upload condition that designates a delivery destination folder ID of the delivery destination folder, a document format process setting value, and an OCR process setting value, for example.
Referring back to
In step S36, the input/output service apparatus 10 stores the scanned image data in the external storage system 30 based on the request data from the MFP 20. After storage of the scanned image data in the external storage system 30 is completed, the input/output service apparatus 10 notifies the MFP 20 that the uploading process has been completed.
Note that in the case where the request data from the MFP 20 includes a designation of one or more input/output service processes, such as a document format process and/or an OCR process, to be executed by the input/output service apparatus 10, processed data resulting from executing the designated input/output service processes on the scanned image data is stored in the external storage system 30.
The setting items “scan color”, “document side”, “document orientation”, and “scan resolution” may be referred to as scan conditions. The scan condition settings are for specifying scan process instructions to the MFP 20 for executing a scan process (input/output device process). The administrator can specify an initial value of a scan condition on which a use restriction is to be imposed and designate the scan condition as a change-disabled scan condition.
The setting items “document format” and “OCR” are settings relating to the functions of the input/output service, and these settings are for specifying the document format of a document format process and the language of an OCR process to be executed by the input/output service apparatus 10. Example values that may be set up for the setting item “OCR” include “Japanese”, “English”, and “OFF (information indicating that the OCR function is not used)”. In the example job setting screen of
The job setting screen of
According to an aspect of the present embodiment, a restriction may be imposed on the value of a job setting to be designated by a user via a job setting screen based on use restriction information generated by the use restriction information generating service apparatus 12, which is different from the MFP application. In this way, an administrator can restrict a user's ability to use a certain parameter for designating an upload condition via a job setting screen.
Note that in the above-described embodiment, an MFP application that provides a scan delivery service has been described as an example. However, aspects of the present invention may also be applied to an MFP application that provides a download print service, for example.
Although the present invention has been described above with reference to certain illustrative embodiments, the present invention is not limited to these embodiments, and numerous variations and modifications may be made without departing from the scope of the present invention.
