     SUMMARY OF INVENTION 
     Technical Problem 
     In a case where a cooperative processing is carried out between a multifunction peripheral and an application that operates on an information processing apparatus, it is preferable to reflect a result of the cooperative processing in the use history information managed by the multifunction peripheral. 
     For example, in both cases (i) where a user make a print request by operating an input section of the multifunction peripheral (in a case of pull printing) and (ii) where the user makes a print request from a web page of an application that operates on the information processing apparatus (in a case of push printing), it is preferable that recording of the number of prints, restriction of the number of prints, and the like be applied to the same account, if the operations carried out in the respective cases are conducted by the same user. That is, both from the viewpoint of user convenience and the viewpoint of user management, use history information of print processings of a single user is preferably managed such that a sum of the number of prints printed by the push printing and the number of prints printed by the pull printing is managed as the use history information of the single user. 
     According to the conventional technique, however, it is impossible to integrate and manage, as use history information of a user, (i) a result which is obtained in a case where the user operates an input section of a multifunction peripheral so as to cause a cooperative processing to be carried out and (ii) a result which is obtained in a case where the user logs in to an application operating on an information processing apparatus and causes a cooperative processing to be carried out. 
     That is, in a case where the user logs in to the application that operates on the information processing apparatus and causes the cooperative processing to be carried out between the application and the multifunction peripheral, the following problems (i) through (iii) may arise. That is, (i) a use history regarding the cooperative processing is reflected only in use history information managed by the information processing apparatus and not in use history information managed by the multifunction peripheral, (ii) use history information of a user is recorded under an account which is different from the user&#39;s account managed by the multifunction peripheral (that is, the use history information is recorded under an account managed in the application that operates on the information processing apparatus and corresponding to the user&#39;s account), and (iii) use history information of a user is erroneously recorded under an account of another user logged in to the multifunction peripheral. 
     Alternatively, the following operation needs to be conducted in order to reflect, in the use history information managed by the multifunction peripheral, the result which is obtained in a case where the user (i) logs in to the application that operates on the information processing apparatus and (ii) causes the cooperative processing to be carried out. That is, after instructing the application that operates on the information processing apparatus to carry out the cooperative processing, the user needs to conduct, from the input section of the multifunction peripheral, an operation for reflecting the result of the cooperative processing in the use history information managed by the multifunction peripheral. 
     The present invention has been made in view of the problems. An object of the present invention is that, in a multifunction peripheral having (i) a first function of carrying out a cooperative processing in accordance with an instruction inputted by the user from an input section of the multifunction peripheral and (ii) a second function of carrying out the cooperative processing in accordance with an instruction from an application that operates on an information processing apparatus which is connected to the multifunction peripheral via a communication network, use history information of users be appropriately managed for each user, regardless of whether the first function has been used or the second function has been used.

     DESCRIPTION OF EMBODIMENTS 
     Embodiment 1 
     The following description will discuss an embodiment of the present invention. 
     (1-1. Overall Arrangement of Multifunction Peripheral Control System  1 ) 
       FIG. 1  is an explanatory diagram illustrating an arrangement of a multifunction peripheral control system  1  in accordance with the present embodiment. As illustrated in  FIG. 1 , the multifunction peripheral control system  1  includes a multifunction peripheral (MFP)  10 , an information processing apparatus (server apparatus)  30 , and a terminal device  60  which are connected to each other via a communication network  50  so as to communicate with each other. Note that the multifunction peripheral control system  1  can include one or a plurality of multifunction peripherals  10 , one or a plurality of information processing apparatuses  30 , and one or a plurality of terminal devices  60 . 
     The communication network  50  may be a wired arrangement, such as IEEE1394, a USB, a power-line carrier, a cable TV line, a telephone line, an ADSL line, or a serial cable; or a wireless arrangement, such as an infrared ray (e.g., IrDA or remote control), Bluetooth (registered trademark), 802.11 radio, HDR, a mobile phone network, a satellite line, or a terrestrial digital network. Further, the multifunction peripheral  10 , the information processing apparatus  30 , and the terminal device  60  are each configured to carry out communication by an HTTP (Hyper Text Transfer Protocol) method, which is a protocol used for communication between a web server and a web browser (e.g., a request and a transmission of a web page). Note, however, that a communication protocol to be used among the multifunction peripheral  10 , the information processing apparatus  30 , and the terminal device  60  is not particularly limited, and another communication protocol can be used. 
     (1-2. Arrangement of Multifunction Peripheral  10 ) 
     The multifunction peripheral  10  is a digital multifunction peripheral or an analog multifunction peripheral which has a function of (i) receiving control information in an HTML format from the information processing apparatus  30  by using HTTP and (ii) carrying out various device functions of the multifunction peripheral  10  on the basis of the control information received from the information processing apparatus  30 . Examples of the device functions encompass a scan function, a print function, a copy function, a facsimile transmission and reception function, and a communication function. Note, however, that the device functions of the multifunction peripheral  10  are not limited to the above-mentioned functions. For example, the multifunction peripheral  10  can be configured not to include some of the above-mentioned functions, and can be configured to have another device function in place of some of the above-mentioned functions or in addition to the above-mentioned functions. 
     The multifunction peripheral  10  includes an operation section  11 , an image reading section  14 , an image forming section  15 , a storage section  16 , a communication section  17 , and a control section  18 . The operation section  11  includes an input section  12  and a display section  13 . The storage section  16  includes an authentication information storage section  16   a , a login user storage section  16   b , a function execution user storage section  16   c , and a management data storage section  16   d . The control section  18  includes a device control section  19 , a browser section  20 , an authentication processing section  21 , and a recording processing section  22 . 
     The operation section  11  is a user interface which (i) notifies a user of various types of information in accordance with an instruction of the control section  18 , (ii) receives an input inputted by the user, and (iii) transmits the input received to the control section  18 . The operation section  11  includes (i) the input section (operation input section)  12  including various input keys and (ii) the display section  13  which is constituted by, for example, an LCD (Liquid Crystal Display) or the like. Note that the operation section  11  can be a touch panel in which the input section  12  and the display section  13  are integral with each other. 
     The image reading section  14  ( i ) includes a scanner and a document conveying section which conveys a document to a position of the scanner and (ii) carries out a scan function of reading, as image data, (a) text, (b) an image, and the like which are printed on the document. Note that the image reading section  14  reads an image at a given resolution. 
     The image forming section  15  is a member for printing, on a recording sheet such as printing paper, an image (text/photograph/graphic) in accordance with image data. According to the present embodiment, an image forming apparatus of an electrophotographic printing method is employed as the image forming section  15 . The image forming apparatus includes a photoreceptor drum, a charging device, an exposure device, a developing device, a transfer device, a fixing device, a paper tray, and the like. Note, however, that the arrangement of the image forming section  15  is not limited to this. For example, an image forming apparatus of an inkjet printing method or an image forming apparatus of another image forming system can be employed. According to the present embodiment, it is possible to carry out, by using the image forming section  15 , (i) a copy function of printing image data inputted from the image reading section  14  and (ii) a printer function of printing image data inputted from an external device. 
     The storage section  16  is a storage section which stores various types of data (operation screen data, various lookup tables, etc.) which are handled by the multifunction peripheral  10 . Further, the storage section  16  includes the authentication information storage section  16   a , the login user storage section  16   b , the function execution user storage section  16   c , and the management data storage section  16   d.    
     The authentication information storage section  16   a  stores user authentication information (e.g., login name and password) of a user to be given permission to use the multifunction peripheral  10 . Note that according to the present embodiment, the multifunction peripheral  10  and the information processing apparatus  30  periodically communicate with each other so that user authentication information stored in the authentication information storage section  16   a  is updated on the basis of user authentication information stored in an authentication information storage section  36   a  (described later) of the information processing apparatus  30 . Alternatively, it is possible to employ an arrangement in which, in a case where either one of (i) the user authentication information stored in the authentication information storage section  36   a  of the information processing apparatus  30  and (ii) the user authentication information stored in the authentication information storage section  16   a  of the multifunction peripheral  10  is updated, the user authentication information is reflected in the other one of (i) and (ii). As such, according to the present embodiment, the information processing apparatus  30  and the multifunction peripheral  10  can use common user authentication information. That is, in a case where a user who has logged in to the multifunction peripheral  10  by operating the input section  12  of the multifunction peripheral  10  is identical to a user who has logged in to an application that operates on the information processing apparatus  30 , a common account is applied to such a user. 
     The login user storage section  16   b  stores login information (e.g., login name) of a user logged in to the multifunction peripheral  10 . 
     The function execution user storage section  16   c  stores user information of a user who has made an execution request (function execution request) for carrying out a cooperative processing in which an application that operates on the information processing apparatus  30  and the multifunction peripheral  10  cooperatively operate together. Note that the function execution user storage section  16   c  can be configured to store not only user information of the user who has made a function execution request to the application that operates on the information processing apparatus  30 , but also user information of a user who has made a function execution request to (i) an application that operates on another device connected to the multifunction peripheral  10  via the communication network  50  or (ii) an application that operates on the multifunction peripheral  10 . 
     The management data storage section  16   d  stores a user management table for managing, for each user, use history information (summary information) of the multifunction peripheral  10  (or of a cooperative processing between the multifunction peripheral  10  and an application that operates on the information processing apparatus  30 ). Note that the management data storage section  16   d  can be arranged such that the user management table stores, in addition to the use history information, information such as (i) a use-possible condition under which each user can use a multifunction peripheral (or a cooperative processing between the multifunction peripheral and the application that operates on the information processing apparatus  30 ) and (ii) a use-restriction condition under which use of the multifunction peripheral (or the cooperative processing between the multifunction peripheral and the application that operates on the information processing apparatus  30 ) for each user is restricted. 
     Note that an arrangement of the storage section  16  is not specifically limited. For example, various conventionally well-known storage sections such as a hard disk can be employed. 
     The communication section  17  is a communication interface which communicates with an external device such as the information processing apparatus  30  via the communication network  50 . According to the present embodiment, as described above, the communication section  17  communicates with the information processing apparatus  30  by using HTTP. 
     The control section  18  is a computer device constituted by (i) an arithmetic processing section (not shown) such as a CPU or a dedicated processor and (ii) a storage section (not shown) such as a RAM, a ROM, or a HDD. The control section  18  realizes a function of each of the device control section  19 , the browser section  20 , the authentication processing section  21 , and the recording processing section  22  by reading out and executing a program, stored in the storage section, for carrying out various information and various controls. 
     The device control section  19  controls an operation of each section of the multifunction peripheral  10 . That is, the device control section  19  controls operations and the like of the operation section  11 , the image scanning section  14 , the image forming section  15 , and the communication section  17 . For example, the device control section  19  controls the operation of the image scanning section  14  so as to obtain data of a scan image. Further, the device control section  19  controls the operation of the image forming section  15  so as to form (output), on a recording material, an image in accordance with image data. 
     Moreover, the device control section  19  ( i ) controls the operation of the communication section  17  so as to communicate with an external resource (e.g., the information processing apparatus  30 ) and (ii) transmits and receives image data, control information, and the like. 
     The browser section (web browser section)  20  operates in accordance with software for browsing a web page. The browser section  20  causes the display section  13  to display an image in accordance with screen data which is supplied from a web server (e.g., a web server section  34  of the information processing apparatus  30 ). Further, in a case where an instruction to an application on the web server is inputted by a user from the input section  12 , the browser section  20  notifies the device control section  19  of information in accordance with the instruction inputted by the user. This causes the device control section  19  to (i) access the application on the web server (e.g., an application section  34  of the information processing apparatus  30 ) via the communication section  17 , (ii) transmit a screen acquisition request, and (iii) obtain, from the application, screen data in accordance with the instruction inputted. Note that it is possible to employ, as the software, software generally used of a web browser. Further, it is possible to employ, as the application on the web server, for example, a homepage content on the Internet, an external application that cooperatively operates together with the multifunction peripheral  10 , or the like. 
     Further, a screen acquisition request from the multifunction peripheral  10  to the web server (e.g., the web server section  34  of the information processing apparatus  30 ) is made by using a GET command or a POST command of an HTTP protocol. The web server transmits, in response, a screen content in accordance with the screen acquisition request received from the multifunction peripheral  10 . In a case where the screen content is written in HTML, the browser section  20  analyzes the screen content, generates screen data, and causes the display section  13  to display a display screen on the basis of the HTML. 
     The authentication processing section  21  carries out a user authentication processing in which (i) user information which is inputted, from the operation section  11 , by a user who intends to use the multifunction peripheral  10  is compared with (ii) user authentication information which (a) is stored in the authentication information storage section  16   a  and (b) is indicative of a user to be given permission to use the multifunction peripheral  10 . As a result of the user authentication processing, in a case where the authentication processing section  21  determines to permit the user to use the multifunction peripheral  10 , (in a case where the authentication processing section  21  determines that the user information inputted from the operation section  11  matches the user authentication information which (a) is stored in advance in the authentication information storage section  16   a  and (b) is indicative of a user to be given permission to use the multifunction peripheral  10 ), the authentication processing section  21  notifies the device control section  19  that the user has been permitted to use the multifunction peripheral  10 . The device control section  19  ( i ) causes the display section  13  to display an operation screen of the multifunction peripheral  10  so that the multifunction peripheral  10  becomes available and (ii) controls the recording processing section  22  so that the login user storage section  16   b  stores the user information of the user with respect to whom the user authentication processing has been carried out (login information of the user who has logged in). 
     The recording processing section  22  controls writing of various types of data in the storage section  16  and reading of various types of data from the storage section  16 . 
     (1-3. Arrangement of Information Processing Apparatus  30 ) 
     As illustrated in  FIG. 1 , the information processing apparatus  30  includes a communication section  31 , a control section  32 , and a storage section  36 . Further, the control section  32  includes a web server section  33 , an application section  34 , and an authentication processing section  35 . Further, the storage section  36  includes an authentication information storage section  36   a  and a login user storage section  36   b.    
     The communication section  31  communicates with the multifunction peripheral  10  and the terminal device  60  via the communication network  50 . Note that the communication section  31  communicates with the multifunction peripheral  10  and the terminal device  60  by using an HTTP communication protocol. 
     The control section  32  is a computer device constituted by (i) an arithmetic processing section (not shown) such as a CPU or a dedicated processor and (ii) a storage section (not shown) such as a RAM, a ROM, or a HDD. The control section  32  realizes a function of each of the web server section  33  and the application section  34  by reading out and executing a program, stored in the storage section, for carrying out various information and various controls. 
     The web server section  33  operates in accordance with software generally used of a web server. The web server section  33  has a function of (i) receiving a request (e.g., an HTTP request) from the multifunction peripheral and the terminal device  60  via the communication section  31 , (ii) obtaining, from the application section  34 , a file, image data, print data, control information, and the like in accordance with the request, and (iii) transmitting the file, the image data, the print data, the control information, and the like to the multifunction peripheral  10  or the terminal device  60  via the communication section  31 . 
     The application section  34  operates in accordance with a predetermined web application in response to an instruction from the web server section  33 . That is, the application section  34  operates in accordance with various web applications that operate on the web server. Examples of the web application encompass (i) an application that provides a homepage content on the Internet and (ii) a multifunction peripheral control application that cooperatively operates together with the multifunction peripheral  10  so as to control an operation of the multifunction peripheral  10 . 
     For example, in a case where a request (an HTTP request) from the multifunction peripheral  10  or the terminal device  60  is a transmission request for transmitting a display screen, the application section  34  operates in accordance with a display screen transmission application. Specifically, the application section  34  ( i ) reads out, from a storage section (not illustrated), HTML data of the display screen which is indicated by the transmission request and (ii) transmits the HTML data to the web server section  33 . This causes the data of the display screen to be transmitted to a device which has transmitted the request from the web server section  33  (the multifunction peripheral  10  or the terminal device  60 ). Further, in a case where a request from the multifunction peripheral  10  or the terminal device  60  is a transmission request for transmitting print data, the application section  34  operates in accordance with a print application. Specifically, the application section  34  ( i ) obtains, from a folder whose name is indicated by the transmission request, print data whose file name is designated and (ii) transmits the print data to the web server section  33 . This causes the print data to be transmitted from the web server section  33  to a device which carries out a print processing (e.g., the multifunction peripheral  10 ). In a case where the transmission request for transmitting the print data is made from the terminal device  60 , the terminal device  60  ( i ) includes, in the transmission request, address information of a device to which the print data is to be transmitted (e.g., the multifunction peripheral  10 ) and (ii) transmits the transmission request to the information processing apparatus  30 . 
     Note that the application section  34  can be configured to execute a plurality of types of applications (web applications). 
     The storage section  36  is a storage section that stores various types of data which are handled by the information processing apparatus  30 . Further, the storage section  36  includes the authentication information storage section  36   a  and the login user storage section  36   b.    
     The authentication information storage section  36   a  stores user authentication information (e.g., login name and password) of a user to be given permission to use an application (web application) that operates on the information processing apparatus  30 . Further, the login user storage section  36   b  stores login information (e.g., login name) of a user logged in to an application. 
     Note that an arrangement of the storage section  36  is not particularly limited. For example, various conventionally well-known storage sections such as a hard disk can be employed as the storage section  36 . 
     (1-4. Arrangement of Terminal Device  60 ) 
     The terminal device  60  has a function of accessing the information processing apparatus  30  via the communication network  50  and using an application (web application) that operates on the application section  34  of the information processing apparatus  30 . An arrangement of the terminal device  60  is not particularly limited. For example, a personal computer, various mobile terminals (e.g., a mobile phone, a smartphone, a tablet terminal, a PDA (Personal Digital Assistance), a portable game machine, etc.) can be employed as the terminal device  60 . 
     As illustrated in  FIG. 1 , the terminal device  60  includes a communication section  61 , a control section  62 , and an operation section  65 . Further, the control section  62  includes a browser section  63  and a device control section  64 . The operation section  65  includes an input section  66  and a display section  67 . 
     The communication section  61  is a communication interface which communicates with an external device such as the information processing apparatus  30  via the communication network  50 . 
     The operation section  65  is a user interface which (i) notifies a user of various types of information in accordance with an instruction of the control section  62 , (ii) receives an input inputted by the user, and (iii) transmits the input received to the control section  62 . The operation section  65  includes (i) the input section (operation input section)  66  including various input keys and (ii) the display section  67  which is constituted by, for example, an LCD (Liquid Crystal Display) or the like. Note that the operation section  65  can be a touch panel in which the input section  66  and the display section  67  are integral with each other. 
     The control section  62  is a computer device constituted by (i) an arithmetic processing section (not shown) such as a CPU or a dedicated processor and (ii) a storage section (not shown) such as a RAM, a ROM, or a HDD. The control section  62  realizes a function of each of the browser section (web browser section)  63  and the device control section  64  by reading out and executing a program, stored in the storage section, for carrying out various information and various controls. 
     The browser section operates in accordance with software for browsing a web page. The browser section causes the display section  67  to display an image in accordance with screen data which is supplied from a web server (e.g., a web server section  34  of the information processing apparatus  30 ). Further, in a case where an instruction is inputted, with respect to an application on the web server, by a user from the input section  66 , the browser section  63  notifies the device control section  64  of information in accordance with the instruction inputted by the user. This causes the device control section  64  to (i) access the application on the web server (e.g., the application section  34  of the information processing apparatus  30 ) via the communication section  61 , (ii) transmit a screen acquisition request, and (iii) obtain, from the application, screen data in accordance with the instruction inputted. Note that it is possible to employ, as the software, software generally used of a web browser. 
     Further, a screen acquisition request from the terminal device  60  to the web server (e.g., the web server section  34  of the information processing apparatus  30 ) is made by using the GET command or the POST command of the HTTP protocol. The web server transmits, in response, a screen content in accordance with the screen acquisition request received from the terminal device  60 . In a case where the screen content is written in HTML, the browser section  63  analyzes the screen content, generates screen data, and causes the display section  67  to display a display screen on the basis of the HTML. 
     The device control section  64  controls an operation of each section of the terminal device  60 . That is, the device control section  64  controls operations of the operation section  65  and the communication section  61 . For example, the device control section  64  ( i ) controls the operation of the communication section  61  so as to communicate with an external resource (e.g., the information processing apparatus  30 ) and (ii) transmits and receives image data, control information, and the like. Further, the device control section  64  controls the operation of the display section  67  to display a display screen in accordance with the image data. Further, the device control section  64  controls the operation of the input section  66  to obtain information indicative of a content of an operation input inputted by the user from the input section  66 . 
     (1-5. Overview of Processing in Multifunction Peripheral Control System  1 ) 
     The following description will discuss an operation of the multifunction peripheral control system  1 . Note that an example is described here in which the application section  34  of the information processing apparatus  30  executes a print application which (i) transmits print data to the multifunction peripheral  10  and (ii) causes the multifunction peripheral  10  to carry out a print processing. Note that a user can use the print application (i) by operating the operation section  11  of the multifunction peripheral  10  and (ii) by operating the operation section  65  of the terminal device  60 . 
       FIG. 2  is a flow chart illustrating a flow of a processing in the multifunction peripheral control system  1  in a case where a user uses the print application by operating the operation section  11  of the multifunction peripheral  10 .  FIG. 3  is a flow chart illustrating a flow of a processing in the multifunction peripheral control system  1  in a case where the user uses the print application by operating the operation section  65  of the terminal device  60 . Further,  FIG. 4  is a flow chart illustrating a flow of a processing in the multifunction peripheral  10  after the multifunction peripheral  10  receives a function execution instruction which is transmitted from the information processing apparatus  30  in the processing illustrated in  FIG. 2 or 3 . 
     (1-5-1. Processing in a Case where Application is Used from Multifunction Peripheral) 
     The following description will discuss, with reference to  FIG. 2 , a processing in a case where a user uses a print application by operating the operation section  11  of the multifunction peripheral  10 . 
     As illustrated in  FIG. 2 , the device control section  19  of the multifunction peripheral  10  ( i ) reads out screen data of an authentication information input screen which screen data is stored in the storage section  16  and (ii) causes the display section  13  to display the authentication information input screen (S 1 ).  FIG. 5  is an explanatory diagram illustrating an example of the authentication information input screen. In the example illustrated in  FIG. 5 , the authentication information input screen is configured such that (i) a user is prompted to input a login name and a password as user authentication information and (ii) the user inputs a login name and a password by operating the input section  12  and then presses a login button so as to input user authentication information. 
     When the authentication processing section  21  of the multifunction peripheral  10  receives the user authentication information inputted by the user via the input section  12  (S 2 ), the authentication processing section  21  carries out a user authentication processing by making comparison between (i) the user authentication information inputted and (ii) user authentication information which (a) is stored in advance in the authentication information storage section  16   a  and (b) is indicative of a user to be given permission to use the multifunction peripheral  10  (S 3 ). The authentication processing section  21  then determines whether or not to permit the user to use the multifunction peripheral  10  (to log in to the multifunction peripheral  10 ) (S 4 ). 
     In a case where the authentication processing section  21  determines in S 4  not to permit the user to use the multifunction peripheral  10  (to log in to the multifunction peripheral  10 ), the device control section  19  returns to the processing in S 1 . The multifunction peripheral  10  can be configured such that the display section  13  displays, at this point, a message indicating that the user authentication processing has failed, a message prompting the user to input again the user authentication information, or the like. 
     On the other hand, in a case where the authentication processing section  21  determines in S 4  to permit the user to use the multifunction peripheral  10  (to log in to the multifunction peripheral  10 ), the recording processing section  22  causes the login user storage section  16   b  to store, as login user information, the user information (e.g., login name) of the user who has logged in to the multifunction peripheral  10  (S 5 ). Note that the login user information is stored only while the user is logged in to the multifunction peripheral  10 . In a case where a logout processing of the user is carried out, the login user information is deleted from the login user storage section  16   b.    
     Further, in a case where the authentication processing section  21  determines in S 4  to permit the user to use the multifunction peripheral  10  (to log in to the multifunction peripheral  10 ), the browser section  20  transmits, to the information processing apparatus  30  via the communication section  17 , a transmission request for transmitting an application selection screen (S 6 ). 
     When the web server section  33  of the information processing apparatus  30  receives the transmission request for transmitting the application selection screen, which transmission request has been transmitted from the multifunction peripheral  10  (S 21 ), the web server section  33  ( i ) causes the application section  34  to generate screen data of an application selection screen for causing the user of the multifunction peripheral  10  to select a desired application from among applications which can be used from the multifunction peripheral  10  and (ii) transmits the screen data to the multifunction peripheral  10  (S 22 ). 
     When the browser section  20  of the multifunction peripheral  10  receives the screen data of the application selection screen from the information processing apparatus  30  via the communication section  17 , the browser section  20  controls the display section  13  to display an application selection screen in accordance with the screen data received (S 7 ). 
       FIG. 4  is an explanatory diagram illustrating an example of an application selection screen which is displayed on the display section  13 . In the example illustrated in  FIG. 4 , three types of applications, that is, applications  1  through  3  are selectable. Note that the multifunction peripheral  10  can be configured such that, for example, information indicative of names and types of the respective applications is displayed on the display section  13 . 
     Subsequently, when the browser section  20  receives an instruction to select an application which instruction has been inputted by the user from the input section  12  (S 8 ), the browser section  20  transmits, to the information processing apparatus  30  via the communication section  17 , a start request (initial screen acquisition request) for starting the application selected by the user (S 9 ). 
     Specifically, according to the present embodiment, for example, as illustrated in  FIG. 7 , the storage section  16  stores, in advance, external application information in which each of applications selectable on the application selection screen is associated with corresponding information indicative of an access destination (application URL) accessed in a case where the each of the applications is selected. Alternatively, the external application information is added to the screen data of the application selection screen transmitted from the information processing apparatus  30  to the multifunction peripheral  10 . The device control section  19  controls the browser section  20  and the communication section  17  to transmit, on the basis of the external application information and to an application URL corresponding to an application selected by the user, a start request for starting the application. Note that the start request for starting the application (application screen acquisition request) is made by using the GET command or the POST command of the HTTP protocol. 
     When the web server section  33  of the information processing apparatus  30  receives the start request for starting the application from the multifunction peripheral  10  (S 23 ), the web server section  33  ( i ) obtains, from the application section  34 , screen data (screen content) of an application in accordance with the start request received and (ii) transmits, in response, the screen data to the multifunction peripheral  10  (S 24 ). 
     When the browser section  20  of the multifunction peripheral  10  receives the screen data of the application from the information processing apparatus  30 , the browser section  20  controls the display section  13  to display a screen in accordance with the screen data (S 10 ). For example, in a case where the screen data is written in HTML, the device control section  19  causes the browser section  20  to analyze a content of the HTML and generate screen data. The device control section  19  then causes the display section  13  to display a screen in accordance with the screen data, so that a screen based on the HTML is displayed. 
     Subsequently, when the browser section  20  receives a function execution request inputted by the user via the input section  12  (S 11 ), the browser section  20  carries out a processing in S 71  and the subsequent processings in  FIG. 4 . The processing in S 71  and the subsequent processings will be described later. 
       FIG. 8  is an explanatory diagram illustrating an example of an application screen which is displayed in the processing in S 10 . In the example illustrated in  FIG. 8 , the print application (i) transmits, to the multifunction peripheral  10 , a display screen which displays a list of print data that a user who is currently logged in to the multifunction peripheral  10  can select as data to be printed from among print data stored in a storage section (not illustrated) of the information processing apparatus  30  and (ii) causes the display section  13  to display the list. Then, in a case where the user selects data to be printed and press a print button (in a case where the user makes a print function execution request), the browser section  20  transmits, to the device control section  19 , a transmission request for transmitting a print request for causing the device control section  19  to request the information processing apparatus  30  to give an instruction to print the print data selected by the user. 
     Note that the application can be configured such that a Java (registered trademark) Script for making a function execution request to the device control section  19  is embedded in the HTML of the screen data (screen content) of the application and when a button in the screen is operated, a Java (registered trademark) Script corresponding to the button is executed so that the function execution request is transmitted from the browser section  20  to the device control section  19 . 
     (1-5-2. Processing in a Case where Application is Used from Terminal Device) 
     The following description will discuss, with reference to  FIG. 3 , a processing in a case where a user uses a print application by operating the operation section  65  of the terminal device  60 . 
     As illustrated in  FIG. 3 , when the device control section  64  of the terminal device  60  receives an instruction to select a web application mode (S 31 ), the device control section  64  transmits a transmission request for transmitting the authentication information input screen to the information processing apparatus  30  (S 32 ). Note that according to the present embodiment, the terminal device  60  has (i) a normal mode in which an application that operates on the terminal device  60  itself is used and (ii) a web application mode in which an application (web application) that operates on the information processing apparatus  30  is used from the terminal device  60  so that a user can select, from the operation section  65 , which one of the two modes is to be used. 
     When the web server section  33  of the information processing apparatus  30  receives the transmission request for transmitting the authentication information input screen transmitted from the terminal device  60  (S 51 ), the web server section  33  reads out screen data of the authentication information screen from the storage section  36  and transmits, in response, the screen data to the terminal device  60  (S 52 ). 
     When the device control section  64  of the terminal device  60  receives the screen data of the authentication information input screen from the information processing apparatus  30  (S 33 ), the device control section  64  controls the display section  67  to display the authentication information input screen in accordance with the screen data (S 34 ). Note that the terminal device  60  can be configured such that the screen data of the authentication information input screen (i) is stored in advance in a storage section (not illustrated) of the terminal device  60  and (ii) is read out so as to be displayed. For example, a screen similar to that illustrated in  FIG. 5  can be employed as the authentication information input screen to be displayed on the display section  67 . 
     Subsequently, when the device control section  64  of the terminal device  60  receives user authentication information inputted by the user on the authentication information input screen via the input section  66  (S 35 ), the device control section  64  transmits, to the information processing apparatus  30 , a user authentication processing request including the user authentication information received (S 36 ). 
     The authentication processing section  35  of the information processing apparatus  30  ( i ) carries out a user authentication processing by making comparison between (A) the user authentication information included in the user authentication processing request received from the terminal device  60  and (B) user authentication information which (a) is stored in advance in the authentication information storage section  36   a  and (b) is indicative of a user to be given permission to use the application (S 54 ) and (ii) determines whether or not to permit the user to use the application (to log in to the application) (S 55 ). 
     In a case where the authentication processing section  35  determines in S 55  not to permit the user to use the application (to log in to the application), the web server section  33  transmits an authentication error notification to the terminal device  60  (S 56 ) and returns to the processing in S 53 . 
     On the other hand, in a case where the authentication processing section  35  determines in S 55  to permit the user to use the application (to log in to the application), the web server section  33  ( i ) transmits an authentication permission notification to the terminal device  60  (S 57 ) and (ii) causes the login user storage section  36   b  to store the user authentication information of the user who has been given permission to log in to the application (S 58 ). 
     When the device control section  64  of the terminal device  60  receives a result of the user authentication processing returned from the information processing apparatus  30  (S 37 ), the device control section  64  determines, in accordance with the result of the user authentication processing, whether or not the user has been given permission to use the application (S 38 ). 
     Then, in a case where the device control section  64  determines in S 38  that the user has not been given permission to use the application (in a case where an authentication error notification is received from the information processing apparatus  30 ), the device control section  64  ( i ) returns to the processing in S 34 , (ii) displays again the authentication information input screen, and (iii) prompts the user to input again the user authentication information. 
     On the other hand, in a case where the device control section  64  determines in S 38  that the user has been given permission to log in to the application, the device control section  19  transmits, to the information processing apparatus  30 , a transmission request for transmitting an application selection screen (S 39 ). 
     When the web server section  33  of the information processing apparatus  30  receives the transmission request for transmitting an application selection screen which transmission request has been transmitted from the multifunction peripheral  60  (S 59 ), the web server section  33  ( i ) generates screen data of an application selection screen for causing the user of the multifunction peripheral  60  to select a desired application from among applications which can be used from the multifunction peripheral  60  and (ii) transmits the screen data to the multifunction peripheral  60  (S 60 ). 
     When the device control section  64  of the terminal device  60  receives the screen data of the application selection screen from the information processing apparatus  30  via the communication section  17 , the device control section  64  controls the browser section  63  and the display section  67  so that the display section  67  displays an application screen in accordance with the screen data received (S 40 ). For example, an application selection screen similar to that illustrated in  FIG. 6  can be employed as the application selection screen. 
     Subsequently, when the device control section  64  receives an instruction to select an application which instruction has been inputted by the user from the input section  66  (S 41 ), the device control section  64  transmits, to the information processing apparatus  30  via the browser section  63  and the communication section  61 , a start request (application screen acquisition request) for starting the application selected by the user (S 42 ). Specifically, according to the present embodiment, for example, as illustrated in  FIG. 7 , the storage section  16  stores, in advance, external application information in which each of applications selectable on the application selection screen is associated with corresponding information indicative of an access destination (application URL) accessed in a case where the each of the applications is selected. The device control section  64  ( i ) controls the browser section  63  and the communication section  61 , (ii) accesses, on the basis of the external application information, an application URL corresponding to the application selected by the user, and (iii) transmits a start request for starting the application to the application URL corresponding to the application. Note that the start request for starting the application (application screen acquisition request) is made by using the GET command or the POST command of the HTTP protocol. 
     When the web server section  33  of the information processing apparatus  30  receives the start request for starting the application from the terminal device  60  (S 61 ), the web server section  33  in response transmits, to the terminal device  60 , screen data (screen content) of an application in accordance with the start request received (S 62 ). 
     When the device control section  64  of the terminal device  60  receives the screen data of the application from the information processing apparatus  30 , the device control section  64  controls the browser section  63  and the display section  67  so that the display section  67  displays a screen in accordance with the screen data (S 43 ). For example, in a case where the screen data is written in HTML, the device control section  64  causes the browser section  63  to analyze a content of the HTML and generate screen data. The device control section  64  then causes the display section  67  to display a screen in accordance with the screen data, so that a screen based on the HTML is displayed. 
     Subsequently, when the device control section  64  receives a function execution request inputted by the user from the input section  66  (S 44 ), the device control section  64  transmits, to the information processing apparatus  30  (a URL corresponding to an application which is currently executed) via the browser section  63  and the communication section  61 , the function execution request inputted from the input section  66  (S 45 ). It is possible to employ an arrangement in which the display section  67  displays, at this point, a message indicating that the function execution request is being made. Note that, for example, an application screen similar to that illustrated in  FIG. 8  can be employed as the application screen. 
     When the web server section  33  of the information processing apparatus  30  receives the function execution request from the terminal device  60  (S 63 ), the web server section  33  ( i ) causes an application section  34  corresponding to the function execution request received to generate a function execution request with respect to the multifunction peripheral  10  and (ii) transmits the function execution request to the multifunction peripheral  10  (S 64 ). At this time, the application section  34  ( i ) reads out, from the login user storage section  36   b , user information of a user who is currently logged in to the application, (ii) includes, in a function execution instruction, the user information of the user currently logged in as user information of a user who has made the function execution request, and (iii) transmits the function execution instruction to the multifunction peripheral  10 . That is, when the multifunction peripheral  10  carries out a function in accordance with a function execution request, the application section  34  includes, in a function execution instruction, an instruction for causing the function to be carried out by setting, as an execution user who carries out the function, a user who is currently logged in to an application. The function execution instruction includes, for example, (i) a control command for controlling a device function of the multifunction peripheral  10 , (ii) various data (e.g., image data, a transmission destination to which data is transmitted, etc.) which are used in the multifunction peripheral  10 , and (iii) the like. 
     The device control section  19  of the multifunction peripheral  10  receives the function execution request transmitted from the information processing apparatus  30  (S 11   b ) and carries out the processing in S 71  and the subsequent processings in  FIG. 4 . The processing in S 71  and the subsequent processings will be described later. 
     (1-5-3. Processing after Multifunction Peripheral Receives Function Execution Instruction) 
     The following description will discuss, with reference to the flow chart illustrated in  FIG. 4 , a processing to be carried out after the multifunction peripheral  10  receives a function execution request from the browser section  20  and the information processing apparatus  30 . 
     When the device control section  19  of the multifunction peripheral  10  receives a function execution request in the processing in S 11  illustrated in  FIG. 2  or in S 11   b  illustrated in  FIG. 3  from the browser section  20  or the information processing apparatus  30 , the device control section  19  determines whether or not the function execution request has been made via the operation section  11  (browser section  20 ) of itself (multifunction peripheral  10 ) (S 71 ). 
     For example, the device control section  19  makes the above-mentioned determination on the basis of an IP address of a transmission source from which the function execution request has been received. That is, in a case where the IP address of the transmission source of the function execution request is an IP address of the multifunction peripheral  10  or a loopback address, the device control section  19  determines that the function execution request has been made via the operation section  11  (browser section  20 ) of the multifunction peripheral  10 . On the other hand, in a case where the IP address of the transmission source of the function execution request is neither the IP address of the multifunction peripheral  10  nor the loopback address, the device control section  19  determines that the function execution request has been made from another device. 
     In a case where the device control section  19  determines in S 71  that the function execution request has been made via the operation section  11  of the multifunction peripheral  10 , the device control section  19  (i) reads out user information which (a) has been stored in the login user storage section  16   b  and (b) is indicative of a user who is currently logged in to the multifunction peripheral  10  and (ii) causes the function execution user storage section  16   c  to store the user information as a function execution request user (S 72 ). 
     On the other hand, in a case where the device control section  19  determines in S 71  that the function execution request has not been made via the operation section  11  of the multifunction peripheral  10 , the device control section determines whether or not the function execution instruction received from the information processing apparatus  30  includes information which designates a function execution user (execution user) (S 73 ). 
     Then, in a case where the device control section  19  determines in S 73  that the function execution instruction includes the information which designates the function execution user (execution user), the device control section  19  causes the function execution user storage section  16   c  to store the user designated by the information as the function execution request user (S 74 ). 
     Note that in a case where the device control section determines in S 73  that the function execution instruction does not include the information which designates the function execution user (execution user), the device control section  19  causes an execution of a function in accordance with the function execution instruction received from the information processing apparatus  30  to be cancelled (S 77 ), and ends the processing. Examples of the case where the function execution instruction does not include the information which designates the function execution user (execution user) encompass a case where a printer driver of the terminal device  60  transmits a print job to the multifunction peripheral  10  via the communication network  50  (in a case of a normal print processing via a network). In this case, user information of an authenticated user is not attached to the print job. Accordingly, it is determined that the function execution instruction does not include the information which designates the function execution user (execution user), and an execution of printing is canceled. 
     After causing, in S 72  or S 74 , the function execution user storage section  16   c  to store the function execution request user, the device control section  19  carries out a function in accordance with the function execution request such that the function is associated with the function execution request user stored in the function execution user storage section  16   c  (such that the function execution request user is set as the execution user) (S 75 ). 
     For example, in a case where the function execution request is an execution request for carrying out a function of (i) obtaining print data from the information processing apparatus  30  (a print application that operates on the application section  34  of the information processing apparatus  30 ) and (ii) carrying out a print processing, the device control section  19  transmits a print data acquisition request to the information processing apparatus  30 , obtains the print data, and carries out the print processing. The multifunction peripheral  10  can be configured such that the display section  13  displays, at this point, a message indicating that a print processing is currently carried out (a function is currently carried out). Further, the multifunction peripheral  10  can be configured such that the device control section  19  ( i ) transmits, to the information processing apparatus  30 , an acquisition request for obtaining a control command for controlling the device function of the multifunction peripheral  10 , (ii) obtains a control command, and (iii) controls the device function of the multifunction peripheral  10  in accordance with the control command. 
     Subsequently, the device control section  19  carries out a summary processing of updating summary information (use history information) of the execution user associated with the function in S 75  (S 76 ), and ends the processing. 
     Note that, according to the present embodiment, the multifunction peripheral  10  is configured such that in a case where the device control section  19  determines in S 73  in  FIG. 4  that the function execution instruction received from the information processing apparatus  30  does not include the information which designates the function execution user (execution user), the device control section  19  causes the execution of the function in accordance with the function execution instruction received from the information processing apparatus  30  to be canceled in S 77 . However, the arrangement of the multifunction peripheral  10  is not limited to this. 
     For example, the multifunction peripheral  10  can be configured such that in a case where the device control section  19  determines in S 73  in  FIG. 4  that the function execution instruction received from the information processing apparatus  30  does not include the information which designates the function execution user (execution user), the device control section  19  ( i ) does not carry out the function in accordance with the function execution instruction, (ii) causes the storage section  16  to store (put on hold) tentatively the function execution instruction, and (iii) carries out the function in accordance with the function execution instruction which has been stored in the storage section  16  since when a given operation was conducted via the operation section  11  of the multifunction peripheral  10 . 
     Examples of the given operation encompass an operation in which a user who has logged in to the multifunction peripheral  10  ( i ) makes a request, from the operation section  11 , to start up a UI (user interface) for causing a function execution instruction, which has been put on hold, to be executed and (ii) selects, from the UI, a function execution instruction (job) which has been put on hold. As such, even in a case where the application that operates on the application section  34  cannot provide user information to the job (e.g., in a case where the application does not have a function of providing user information to the job), it is possible to cause the multifunction peripheral  10  to carry out a processing in accordance with the function execution request received from the application. 
       FIG. 9  is an explanatory diagram illustrating an example of a user management table for managing summary information (use history information) of each user. According to the present embodiment, the management data storage section  16   d  stores the user management table. In a case where a processing is carried out using the device function of the multifunction peripheral  10  (or in a case where the cooperative processing is carried out between the multifunction peripheral  10  and the application that operates on the information processing apparatus  30 ), the device control section  19  controls the recording processing section  22  to update, in the user management table, the summary information of a user (execution user) who has made the function execution request for carrying out the function. For example, in the example illustrated in  FIG. 9 , in a case where a user A carries out a print processing in which the number of prints is 10, 10 is added to the number of prints carried out by the user A. That is, since the number of prints before the function is carried out by the user A is 20 in the example illustrated in  FIG. 9 , 10, which is the number of prints having been newly carried out by the user A, is added, so that the number of prints carried out by the user A is updated to 30. 
     (1-5-4. Example of Data Transmission and Reception in a Case where Application is Used from Multifunction Peripheral) 
       FIG. 10  is an explanatory diagram illustrating a flow of data in the processing in S 8  and the subsequent processings in  FIG. 2 . As illustrated in  FIG. 10 , when the browser section  20  receives, in S 8  in  FIG. 2 , the instruction to select an application which instruction has been inputted by the user, the browser section  20  transmits an initial screen acquisition request (HTTP Page request) to the application section  34  of the information processing apparatus  30  (T 1 ). 
     When the application section  34  receives the initial screen acquisition request, the application section  34  transmits, in response, screen data of an initial screen in accordance with the initial screen acquisition request (HTTP Page response) (T 2 ). 
     The browser section  20  ( i ) causes the display section  13  to display an initial screen in accordance with the screen data of the initial screen obtained from the application section  34 , (ii) obtains a print request (function execution request) inputted by the user on the initial screen via the input section  12 , and (iii) transmits the print request to the device control section  19  (T 3 ). 
     When the device control section  19  receives the print request (function execution request), the device control section  19  transmits a login user information request to the recording processing section  22  (T 4 ). The recording processing section  22  ( i ) reads out login user information (user information which (a) is stored in the login user storage section  16   b  and (b) is indicative of a user who is currently logged in to the multifunction peripheral  10 ) and (ii) transmits the login user information to the device control section  19  (T 5 ). 
     Further, the device control section  19  responds to the browser section  20  that the device control section  19  has received the print request (function execution request) (T 6 ). When the browser section  20  receives this response, the browser section  20  causes the display section  13  to display a message that the function is currently being carried out. 
     Further, the device control section  19  transmits a print data acquisition request (function execution request) to the application section  34  of the information processing apparatus  30  (T 7 ). The application section  34  transmits print data (function execution instruction) in accordance with the print data acquisition request to the multifunction peripheral  10  (T 8 ). 
     When the device control section  19  receives the print data transmitted from the information processing apparatus  30 , the device control section  19  carries out a processing of determining whether or not the processing in S 71  in  FIG. 4 , that is, the print request (function execution request) corresponding to the print data (function execution instruction) has been made via the operation section  11  of the multifunction peripheral  10 . 
     Then, since the print request has been made via the operation section  11  of the multifunction peripheral  10  in the example illustrated in  FIG. 10 , the print processing is carried out as illustrated in S 72  in  FIG. 4  so that a user who is currently logged in to the multifunction peripheral (a user corresponding to a user of the login user information obtained in T 5 ) is set as the execution user. Note that in the example illustrated in  FIG. 10 , the login user information is obtained before the print data acquisition request is transmitted to the application section  34 . However, a timing when the login user information is obtained is not limited to this. It is also possible to obtain the login user information as needed after the print data is obtained. 
     Subsequently, the device control section  19  notifies, to the recording processing section  22 , summary information in which a result of the print processing is taken into consideration (T 9 ). The recording processing section  22  ( i ) updates the summary information which (a) is stored in the storage section  16  and (b) is indicative of the execution user and (ii) transmits, to the device control section  19  in response, a notification that the update of the summary information is complete (T 10 ). 
     (1-5-5. Example of Data Transmission and Reception in a Case where Application is Used from Terminal Device) 
       FIG. 11  is an explanatory diagram illustrating a flow of data in the processing in S 44  and the subsequent processings in  FIG. 3 . As illustrated in  FIG. 11 , when the device control section  64  of the terminal device  60  receives, in S 44  in  FIG. 3 , the instruction to select an application which instruction has been inputted from the user, the device control section  64  transmits a print request (function execution request) to the application section  34  of the information processing apparatus  30  via the browser section  63  (T 11 ). The application section  34  ( i ) transmits, to the terminal device  60 , a notification that the print request has been received (T 12 ) and (ii) transmits the print request to the multifunction peripheral  10  (T 13 ). When the device control section  19  of the multifunction peripheral  10  receives the print request from the application section  34 , the device control section  19  ( i ) obtains login user information (user information of a user logged in to the application) included in the print request and (ii) transmits a print data acquisition request to the application section  34  (T 14 ). When the application section receives the print data acquisition request, the application section  34  transmits print data in accordance with the print data acquisition request to the multifunction peripheral  10  (T 15 ). 
     When the device control section  19  receives the print data transmitted from the information processing apparatus  30 , the device control section  19  carries out the processing in S 71  in  FIG. 4 , that is, a processing to determine whether or not the print request (function execution request) corresponding to the print data (function execution instruction) has been carried out via the operation section  11  of the multifunction peripheral  10 . 
     Then, since the print request has been made via the operation section  65  of the terminal device  60  in the example illustrated in  FIG. 11 , the print processing is carried out as illustrated in S 74  in  FIG. 4  so that the user who is currently logged in to the application (the user corresponding to the user of the login user information included in the print request obtained in T 13 ) is set as the execution user. 
     Subsequently, the device control section  19  notifies, to the recording processing section  22 , summary information in which a result of the print processing is taken into consideration (T 16 ). The recording processing section  22  ( i ) updates the summary information which (a) is stored in the storage section  16  and (b) is indicative of the execution user and (ii) transmits, to the device control section  19  in response, a notification that the update of the summary information is complete (T 17 ). 
     As has been described, according to the present embodiment, in a case where a user who has made a function execution request is identical to a user who has logged in to the multifunction peripheral  10 , the user who has logged in to the multifunction peripheral  10  is set as the execution user. On the other hand, in a case where the user who has made the function execution request is identical to a user who, from the terminal device  60 , has logged in to the application that operates on the application section  34 , the user who has logged in to the application is set as the execution user. 
     This makes it possible to appropriately summarize, for each user, a history of use of the multifunction peripheral  10  etc. for each user, regardless of whether the user has logged in via the multifunction peripheral  10  or the user has logged in via the terminal device  60 . Further, after the application that operates on the information processing apparatus  30  is instructed to carry out the cooperative processing, it is unnecessary to conduct, with respect to the input section  12  of the multifunction peripheral  10 , an operation for reflecting a result of the cooperative processing in the use history information managed by the multifunction peripheral  10 . This allows an improvement in user convenience. 
     The present embodiment has discussed a case where the application executed by the application section  34  of the information processing apparatus  30  is a print application. Note, however, that the application executed by the application section  34  is not limited to this. 
     For example, the application can be a scan transmission application in which the application section  34  causes the multifunction peripheral  10  to carry out a scan processing and a transmission processing of transmitting scan data. Then, in a case where the user selects the scan transmission application in S 8  in  FIG. 2 , the device control section  19  of the multifunction peripheral  10  transmits in S 9 , in  FIG. 2  to the information processing apparatus  30 , a start request for starting the scan device application. When the application section  34  receives the start request for starting the scan device application (S 23  in  FIG. 2 ), the application section  34  ( i ) includes, in the application screen of the scan transmission application, a scan condition and information on a transmission destination to which the scan data is transmitted and (ii) transmits, in response, the application screen to the multifunction peripheral  10  (S 24  in  FIG. 2 ). Subsequently, in the multifunction peripheral  10 , (i) an execution user is specified by a processing similar to that illustrated in  FIG. 4  and (ii) the scan processing and the transmission processing of the scan data are carried out. 
     According to the present embodiment, for each user, (i) user information of the user in a case where the user logs in to the multifunction peripheral  10  via the operation section  12  of the multifunction peripheral  10  and (ii) user information of the user in a case where the user logs in to an application that operates on the application section  24  are shared by the each user. Note, however, that the present embodiment is not limited to this. For example, the multifunction peripheral  10  can be configured such that (i) different user information is used for a single user in (a) a case where the user logs in to the multifunction peripheral from the operation section  12  of the multifunction peripheral  10  and (b) a case where the user logs in to the application that operates on the application section  24  and (ii) in both cases (a) and (b), use history information of the user is to be managed as use history information of the single user. That is, the multifunction peripheral  10  can be arranged such that (i) user information of (a) a user in a case where the user logs in to the multifunction peripheral from the operation section  12  of the multifunction peripheral  10  and user information of (b) a user in a case where the user logs in to the application that operates on the application section  24  are stored such that the user information of the respective users (a) and (b) are associated with each other and (ii) (A) use history information of the user (a) and (B) use history information of the user (b) are managed in common between a case in which the user logs in with the information (A) and a case in which the user logs in with the information (B). 
     Embodiment 2 
     The following description will discuss another embodiment of the present invention. Note that for easy explanation, the same reference signs will be given to a member having the same function as a member described in Embodiment 1, and descriptions on such a member will be omitted. 
     In Embodiment 1, when the device control section  19  of the multifunction peripheral  10  receives a function execution request from the browser section  20  or the information processing apparatus  30 , the device control section  19  determines whether or not the function execution request was made from the operation section  11  (browser section  20 ) of itself (the multifunction peripheral  10 ). In a case where the device control section  19  determines that the function execution request was made from the operation section  11  of the multifunction peripheral  10 , a user currently logged in to the multifunction peripheral  10  is set as an execution user. In contrast, according to the present embodiment, a user different from a user who actually logged in to a multifunction peripheral  10  and made a function execution request can be designated as an execution user. For example, in a case where a secretary of a president of a company logs in to the multifunction peripheral  10  and carries out printing in place of the president, it is possible to (i) carry out printing by setting the president, not the secretary, as the execution user and (ii) set the president as a person with respect to whom a result of carrying out printing can be summarized. 
     A device arrangement of the multifunction peripheral control system  1  in accordance with the present embodiment is identical to that in Embodiment 1, except that (i) the application screen displayed in the processing in S 10  in  FIG. 2  or the processing in S 43  in  FIG. 3  is an application screen illustrated in  FIG. 12  instead of the application screen illustrated in  FIG. 8 , and (ii) after the multifunction peripheral  10  receives a function execution request in S 11  in  FIG. 2  or at S 11   b  in  FIG. 3 , the multifunction peripheral  10  carries out the processing shown in  FIG. 14  in place of the processing shown in  FIG. 4 . 
       FIG. 12  is an explanatory diagram illustrating an example of an application screen displayed on the display section  13  of the multifunction peripheral or on the display section  67  of the terminal device  60  in S 10  in  FIG. 2  or S 43  in  FIG. 3 . In the example illustrated in  FIG. 12 , in addition to an item (an item for selecting a function for which a function execution request is to be made) for selecting print data, an item (a list of users available to select as an execution user) for selecting a user with respect to whom results of carrying out printing are counted in a summary processing is displayed. 
     Note that when the application section  34  of the information processing apparatus  30  receives an application start request in S 23  in  FIG. 2  or S 61  in  FIG. 3 , the application section  34  responds by (i) including, in screen data of the application screen to be transmitted in response to the request, an item for selecting a user to be designated as an execution user and (ii) transmitting the screen data. 
     Specifically, as illustrated in  FIG. 13 , the information processing apparatus  30  has registered therein users by groups and users belonging to the same group can designate each other as an execution user. The application section  34  of the information processing apparatus  30  ( i ) extracts users who belong to the same group as the user who has made the application start request, (ii) generates an application screen which includes an item for selecting a user to be designated as an execution user out of the extracted users, and (iii) transmits the application screen to the multifunction peripheral  10  or the terminal device  60 . 
     Further, in a case where the application section  34  transmits the application screen to the multifunction peripheral  10 , the application section  34  includes, in the screen data of the application screen, (or adds, to the screen data of the application screen) information for setting, as an execution user who carries out a function in accordance with a function execution request, an execution user selected by the user by inputting to the application screen an instruction to select the execution user. 
     Further, in a case where the application section  34  transmits the application screen to the terminal device  60 , the application section  34  ( i ) receives, from the terminal device  60  and together with the function execution request in S 63  in  FIG. 3 , an execution user selected by the user by inputting to the application screen an instruction to select the execution user and (ii), when the application section  34  transmits the function execution request to the multifunction peripheral  10  in S 64 , the application section (i) includes, in the function execution request, information for causing the user designated by the user of the terminal device  60  to set a function in accordance with the function execution request and (ii) transmits the function to the multifunction peripheral  10 . 
     Subsequently, when the browser section  20  of the multifunction peripheral  10  receives a function execution request in the processing in S 11  in  FIG. 2  or the processing in S 11   b  in  FIG. 13 , the browser section  20  carries out the processing shown in  FIG. 14 . 
     That is, when the device control section  19  of the multifunction peripheral  10  receives, from the browser section  20  or the information processing apparatus  30 , a function execution request and an instruction to designate an execution user in S 11  in  FIG. 2  or S 11   b  in  FIG. 3 , the device control section  19  determines, on the basis of information included in the function execution request received from the information processing apparatus  30  (or information added to the device execution request), whether to set, as an execution user, a user whose selection has been instructed from the operation section  11  of multifunction peripheral  10  or set, as an execution user, a user designated by the application section  34  (S 81 ). 
     Then, in a case where the device control section  19  determines in S 81  to set, as an execution user, the user whose selection has been instructed via the operation section  11  of the multifunction peripheral  10 , the device control section  19  causes the storage section  16   c  to store, as a function execution request user, a user whose selection has been instructed from the operation section  11  of the multifunction peripheral  10  by a user logged in to the multifunction peripheral  10  in S 11  in  FIG. 2  (S 82 ). 
     On the other hand, in a case where the device control section  19  determines in S 81  not to set, as an execution user, the user whose selection has been instructed from the operation section  11  of the multifunction peripheral  10 , (in a case where the device control section  19  determines to set, as an execution user, the user designated by the application section  34 ), the device control section  19  determines whether or not the function execution instruction from the information processing apparatus  30  includes information which designates a function execution user (execution user) (S 83 ). 
     Then, in a case where the device control section  19  determines in S 83  that the function execution instruction includes the information which designates a function execution user (execution user), the device control section  19  causes the function execution user storage section  16   c  to store, as a function execution request user, a user designated by the information (S 84 ). Note that in a case where the device control section  19  determines in S 83  that the function execution instruction does not include information which designates a function execution user (execution user), the device control section  19  causes the execution of the function in accordance with the function execution instruction received from the information processing apparatus  30  to be canceled (S 87 ), and ends the processing. 
     After the device control section  19  causes the function execution request user to be stored in the function execution user storage section  16   c  in S 82  or S 84 , the device control section  19  carries out a function in accordance with the function execution request such that the function is associated with the function execution request user stored in the function execution user storage section  16   c  (such that the function execution request user is set as the execution user) (S 85 ). 
     Subsequently, the device control section  19  carries out a summary processing of updating summary information of the execution user associated in S 85  (S 86 ), and ends the processing. 
       FIG. 15  is an explanatory diagram illustrating a flow of data in a case where the user logged in to the multifunction peripheral  10  makes a function execution request by designating the execution user from the operation section  11 . 
     As shown in  FIG. 15 , when the browser section  20  receives from the user an instruction to select an application in S 8  shown in  FIG. 2 , the browser section  20  transmits, to the application section  34  of the information processing apparatus  30 , an initial screen acquisition request (HTTP Page request) (T 21 ). 
     When the application section  34  receives the initial screen acquisition request, the application section  34  in response transmits screen data (HTTP Page response) of an initial screen in accordance with the request (T 22 ). 
     The browser section  20  ( i ) causes an initial screen to be displayed on the display section  13  on the basis of the screen data of the initial screen obtained from the application section  34 , (ii) obtains a print request (function execution request) and an instruction to designate an execution user which are inputted to the initial screen by the user from the input section  12  and (iii) transmits the print request and the instruction to the device control section  19  (T 23 ). 
     When the device control section  19  receives the print request (function execution request), the device control section  19  determines, on the basis of information included in the print request, whether to set, as an execution user, a user whose selection has been instructed by the user logged in to the multifunction peripheral  10  or to set, as an execution user, a user designated by the application section  34 . Further, the device control section  19  notifies the browser section  20  that the device control section  19  has received the print request (function execution request) (T 24 ), and the browser section  20  notified causes the display section  13  to display an indication that a printing process is being carried out (the function is being carried out). 
     Further, the device control section  19  transmits a print data acquisition request (function execution request) to the application section  34  of the information processing apparatus  30  (T 25 ), and the application section  34  transmits, to the multifunction peripheral  10 , print data (function execution instruction) in accordance with the print data acquisition request (T 26 ). 
     When the device control section  19  receives the print data transmitted from the information processing apparatus  30 , the device control section  19  ( i ) sets an execution user in accordance with a result of determination of whether to set, as the execution user, a user whose selection has been instructed by the user logged in to the multifunction peripheral  10  or to set, as the execution user, a user designated by the application section  34  and (ii) carries out printing processing such that the printing processing is associated with the execution user set. 
     Subsequently, the device control section  19  notifies the recording processing section  22  of (i) summary information which takes account of a result of the print processing and (ii) information indicative of the execution user (T 27 ), and the recording processing section  22  ( i ) updates summary information, stored in the storage section  16 , on the execution user and (ii) transmits to the device control section  19  in response a notification that the update has been completed (T 28 ). 
     As described above, according to the present embodiment, a user who logs in to the multifunction peripheral  10  can select an execution user and cause a function of the multifunction peripheral  10  to be carried out such that the function is associated with the execution user. 
     Accordingly, in a case where, for example, a user who logs in to the multifunction peripheral  10  carries out a function in place of another user, a summary processing (e.g., billing processing) can be carried out under the name of the another user. This allows the summary processing to be carried out appropriately in accordance with the reality of usage of the multifunction peripheral  10 . 
     Embodiment 3 
     The following description will discuss still another embodiment of the present invention. Note that for easy explanation, the same reference signs will be given to a member having the same function as a member described in any of the embodiments described above, and descriptions on such a member will be omitted. 
     In Embodiments 1 and 2, a user authentication processing of a user who logs in to the multifunction peripheral  10  is carried out by the authentication processing section  21  of the multifunction peripheral  10 . 
     In contrast, in the present embodiment, a user authentication processing of a user who logs in to the multifunction peripheral  10  is carried out by an authentication server  80  which is connected to the multifunction peripheral  10  via the communication network  50  so as to communicate with the multifunction peripheral  10 . 
       FIG. 16  is an explanatory diagram illustrating an example of an arrangement of the multifunction peripheral control system  1  in accordance with the present embodiment. In the example illustrated in  FIG. 16 , the authentication server  80  is connected to the communication network  50  in addition to the multifunction peripheral  10 , the information processing apparatus  30 , and the terminal device  60 . Further, the authentication processing section  21  and the authentication information storage section  16   a  in the multifunction peripheral  10  illustrated in  FIG. 1  and the authentication processing section  35  and the authentication information storage section  36   a  in the information processing apparatus  30  illustrated in  FIG. 1  are omitted, and an authentication processing section  83  and an authentication information storage section  86 , which carry out functions of the authentication processing section  21 , the authentication information storage section  16   a , the authentication processing section  35 , and the authentication information storage section  36   a  are included in the authentication server  80 . 
     The authentication server  80  includes a communication section  81 , a control section  82 , and a storage section  85 . The control section  82  includes the authentication processing section  83  and a user management section  84 . The storage section  85  includes the authentication information storage section  86  and a management table storage section  87 . 
     The communication section  81  is a communication interface which carries out communication with external devices, such as the multifunction peripheral  10 , the information processing apparatus  30 , and the terminal device  60 , via the communication network  50 . 
     The control section  82  is a computer device constituted by an arithmetic processing section (not shown) such as a CPU or a dedicated processor and a storage section (not shown) such as a RAM, a ROM, or a HDD. The control section  82  realizes a function of each of the authentication processing section  83  and the user management section  84  by reading out and executing a program, stored in the storage section, for carrying out various information and various controls. 
     The authentication information storage section  86  stores user authentication information (e.g., a login name and a password) on a user to be given permission to use the multifunction peripheral  10 . The authentication information storage section  86  stores user authentication information (e.g., a login name and a password) of a user to be given permission to use an application executed on the application section  34 . 
     Note that it is possible to employ an arrangement in which the authentication server  80  carries out a user authentication processing with respect to a plurality of multifunction peripherals connected to the multifunction peripheral control system  1 . In this case, the authentication information storage section  86  may store, for each of the plurality of multifunction peripherals, user authentication information of a user to be given permission to use the each of the plurality of multifunction peripherals. Similarly, it is possible to employ an arrangement in which the authentication server  80  carries out a user authentication processing with respect to a plurality of applications (web applications) executed in the multifunction peripheral control system  1 . In this case, the authentication information storage section  86  may store, for each of the plurality of applications, user authentication information of a user to be given permission to use the each of the plurality of applications. Or alternatively, user authentication information common to the plurality of multifunction peripherals and/or the plurality of applications may be used as user authentication information of each user, so that each user can log in using the user authentication information that is common to the plurality of multifunction peripherals and/or the plurality of applications. 
     In a case where the authentication processing section  83  carries out a user authentication processing of a user who intends to use the multifunction peripheral  10 , the authentication processing section  83  ( i ) carries out a user authentication processing in which user information inputted from the operation section  11  by a user who intends to use the multifunction peripheral  10  is compared with user authentication information, stored in the authentication information storage section  86 , on a user to be given permission to use the multifunction peripheral  10  and (ii) transmits a result of the user authentication processing to the multifunction peripheral  10 . Note that the user information inputted from the operation section by the user who intends to use the multifunction peripheral  10  is transmitted by the device control section of the multifunction peripheral  10  from the communication section  17  to the authentication server  80 . Further, in a case where it is determined by the user authentication processing that the user is to be given permission to use the multifunction peripheral  10 , the device control section  19  of the multifunction peripheral  10  (i) causes an operation screen of the multifunction peripheral  10  to be displayed on the display section  13  so as to make the multifunction peripheral  10  available and (ii) causes the login user storage section  16   b  to store user information (login information of the user who has logged in) of the user whose user authentication processing has been carried out. 
     Further, in a case where the authentication processing section  83  carries out a user authentication processing of a user who intends to use an application executed in the application section  34 , the authentication processing section  83  ( i ) carries out a user authentication processing in which user information inputted from the operation section  65  of the terminal device by the user who intends to use the application is compared with user authentication information, stored in the authentication information storage section  86 , of a user to be given permission to use the application and (ii) transmits a result of the user authentication processing to the terminal device  60 . 
     Note that the user information inputted from the operation section  65  by the user who intends to use the application is transmitted by the device control section  64  of the terminal device  60  from the communication section  17  to the authentication server  80 . Further, in a case where it is determined by the user authentication processing that the user is to be given permission to use the application, the device control section  64  of the terminal device  60  ( i ) causes an operation screen of the application to be displayed on the display section  67  so as to make the application available and (ii) causes the login user storage section  36   b  to store user information (login information of the user who has logged in) of the user whose user authentication processing has been carried out. 
     The management table storage section  87  stores, for each user, (i) use history information, for each user, of the multifunction peripheral  10  and/or an application (an application which operates in the application section  34 ) (e.g., the accumulated total number of prints, accumulated total number of scans, the number of transmission times of image data, storage capacity for image data) and use-possible condition information (e.g., an upper limit of the number of printable sheets, an upper limit of the number of scans, an upper limit of the number of image data transmission times, an upper limit of the image data storage capacity, and the like). 
     The user management section  84  ( i ) obtains, from the multifunction peripheral  10 , use history information of the multifunction peripheral  10  and/or the application (e.g., information on the number of prints, the execution user, etc.) and (ii) updates information related to the user and stored in the management table storage section  87 . 
     Further, in a case where the user management section  84  receives, from the multifunction peripheral  10  or the terminal device  60 , an inquiry as to whether or not a function execution request made by a user can be carried out, the user management section  84  ( i ) determines, on the basis of (a) a content of the function execution request made by the user and (b) use-possible condition information stored in the management table storage section  87 , whether or not a processing can be carried out in accordance with the function execution request and (ii) responds to the multifunction peripheral  10  or the terminal device  60 .
