BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an information processing apparatus, an entry information management method and a certification function control method. More particularly, the present invention relates to an information processing apparatus and an entry information management method in which manipulations of a user on entry information can be restricted, and an information processing apparatus and a certification function control method in which one or more certification functions can be provided to one or more programs. 2. Description of the Related Art In recent years, an image processing apparatus, which is an embodiment of an information processing apparatus, accommodating individual device functions, such as a printer, a copier, a facsimile and a scanner, in a single housing (hereinafter called a multifunctional product) has been recognized. This multifunctional product includes a display part, a print part and an image formation part in a single housing together with four software items corresponding to the printer, the copier, the facsimile and the scanner. By switching the software items, the multifunctional product can work as any of the printer, the copier, the facsimile and the scanner. Japanese Laid-Open Patent Application No. 2002-084383 discloses an embodiment of the above-mentioned multifunctional product. In such a multifunctional product, user information on users allowed to use the multifunctional product is managed as entry information. The entry information may include, for example, names, e-mail address, FAX numbers, passwords, user names, use restriction information and charge data. The entry information managed in a multifunctional product is set to allow all users to view all information items of the entry information other than some information items such as passwords. On the other hand, the entry information managed in a multifunctional product is normally set to allow only a user administrator to edit information items of the entry information. Alternatively, the entry information managed in a multifunctional product may be set to allow all users to edit information items of the entry information. Japanese Laid-Open Patent Application No. 2000-015898 discloses an embodiment of a user information management method. In conventional multifunctional products, entry information on all users is managed as address books, and access authority to the entry information (for example, permission of viewing or editing the entry information) is set for each address book. Consequently, the conventional multifunctional products do not allow the access authority to the entry information to be set in detail. It is noted that a user administrator is allowed to set the access authority to the entry information. In recent years, multifunctional products are required to have advanced security functions. Thus, it is undesirable to allow to set access authority to entry information for a whole address book from the viewpoint of compatibility between robust security functions and friendly manipulation to the entry information. Also, conventional multifunctional products allow only user administrators to set access authority to the entry information. That can be considered to be problematic from the viewpoint of improving friendly manipulation of the entry information. In addition, when a conventional multifunctional product operates as a printer, a copier, a facsimile or a scanner, the multifunctional product uses an authentication function to authenticate whether a user has authority to use the printer, the copier, the facsimile or the scanner, and uses a charge function to charge a fee. Japanese Laid-Open Patent Application No. 2002-288737 discloses an image processing system that a user can use when a card is set in a card reader thereof. In such a conventional multifunctional product, it is necessary to set the authentication function and the charge function for the whole multifunctional product. For this reason, the conventional multifunctional product has difficult compatibility between good security and easy manipulation of the authentication and charge functions of the multifunctional product. In general, a newer type or a newer version of multifunctional product is provided with more secure authentication and charge functions. In order to use new authentication and charge functions in a conventional multifunctional product, however, it is necessary to modify programs thereof. Thus, there is a problem in that such new authentication and charge functions cannot be easily added. SUMMARY OF THE INVENTION It is a general object of the present invention to provide an information processing apparatus, an entry information management method and a certification function control method in which one or more of the above-mentioned problems are eliminated. A first more specific object of the present invention is to provide an information processing apparatus and an entry information management method that achieve compatibility of improvement of security functions and convenience of entry information. A second more specific object of the present invention is to provide an information processing apparatus and a certification function control method that can realize secure and convenient certification functions and add a new certification function easily. In order to achieve the above-mentioned objects, there is provided according to one aspect of the present invention an information processing apparatus, including: a restriction part restricting an operation available to a user on the information processing apparatus based on a status of the user; and a setting part setting the status of the user. In an embodiment of the invention, the information processing apparatus may manage one or more entry information elements and impose a restriction on user's manipulation on an entry information element, the setting part may includes a first registration function registering manipulation authority to allow a manipulation on an entry information element and setting authority to allow setting of the manipulation authority in association with the entry information element and one or more users, and the restriction part may include a first restriction function restricting a manipulation of the users on the entry information element in accordance with the manipulation authority. In an embodiment of the invention, the information processing apparatus may allow a user to cancel use restriction on a program and the user to use the program, the setting part may include a setting function associating one or more programs having use restriction with one or more certification unit to cancel the use restriction of the programs, and the restriction part may include a use function, when a user cancels use restriction of a program by using a certification unit associated with the program, allowing the user to use the program. Additionally, there is provided according to another aspect of the invention a method of managing entry information for an information processing apparatus that manages one or more entry information elements and restricts a manipulation of one or more users on the entry information elements, the method including steps of: registering manipulation authority to allow a manipulation on an entry information element and setting authority to allow setting of the manipulation authority in association with the entry information element and one or more users; and restricting a manipulation of the users on the entry information element in accordance with the manipulation authority. Additionally, there is provided according to another aspect of the invention a method of controlling a certification function for an information processing apparatus that allows a user to cancel use restriction on a program and the user to use the program, the method including steps of: associating one or more programs having use restriction with one or more certification unit to cancel the use restriction of the programs; and allowing, when a user cancels use restriction of a program by using a certification unit associated with the program, the user to use the program.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In these embodiments, a multifunctional product is described as an embodiment of an information processing apparatus according to the present invention. However, the present invention is not limited to the embodiments, and may be embodied as any information processing apparatus capable of restricting user's manipulations on entry information. A description is given, with reference to FIG. 1 through FIG. 46, of a multifunctional product according to a first embodiment of the present invention. First, some data structures of entry information of a multifunctional product that restricts user's manipulations on the entry information are described to facilitate understanding of the present invention. FIG. 1 shows a first exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. Referring to FIG. 1, an entry information element 1001 represents information on a single user for a multifunctional product. Specifically, the entry information element 1001 includes information items such as a serial number, an owner ID, an owner group 1002, a user group 1003, a registration number, a name, an email address, a FAX number, an SMB/FTP (Server Message Block/File Transfer Protocol) name, a password, an SMB/FTP password, a user name, use restriction information and charge data. The owner group 1002 includes one or more users having setting authority. The term �setting authority� indicates permission or denial of setting various types of manipulations such as addition of a user to the user group 1003, deletion of a user from the user group 1003, viewing of a user on the entry information element 1001 and editing of a user on the entry information element 1001. Here, a user having the setting authority can add and delete a user to/from the owner group 1002. In the user group 1003, one or more users having manipulation authority are registered. The term �manipulation authority� indicates permission or denial of viewing, editing and other manipulations on the entry information element 1001. In the user group 1003 in FIG. 1, viewing authority over a viewing manipulation is represented as �R�, and editing authority over an editing manipulation is represented as �W�. Here, the user group 1003 may include not only a user but also a group 1004 representing a collection of one or more users. An �owner ID� of the owner group 1002 and the user group 1003 is an identifier of the user represented by the entry information element 1001. A �user administrator ID� is an identifier of a user that manages the entry information element 1001. A �creator ID� is an identifier of a user that has created the entry information element 1001. A �user ID� is an identifier of a user. The use restriction information of the entry information element 1001 includes permission or denial, for example, of monochrome copying, two-color copying, full-color copying, monochrome printing, single-color printing, two-color printing, full-color printing, FAX transmission, scanner reading, document box printing, network accessing and other operations. In the entry information element 1001 in FIG. 1, the owner group 1002 and the user group 3 are set for the whole entry information element 1001. In other words, manipulation authority and setting authority are determined as access rules for the whole entry information element 1001. FIG. 2 shows a second exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. In FIG. 2, the entry information element 1001 is the same as that in FIG. 1 except for a portion of the user group 1003, and the description of the same portion is omitted. In the user group 1003 in FIG. 1, viewing authority and editing authority of the group 1004, which represents a collection of one or more users, are set for the whole group 1004. On the other hand, in the user group 1003 in FIG. 2, the viewing authority and the editing authority of a group 1005, which represents a collection of one or more users, are set for each user of the group 1005. In other words, according to the entry information element 1005 in FIG. 2, the viewing authority and the editing authority can be set for each user of the group 1005. Thus, according to in the second exemplary entry information element 1001, access rules can be defined in further detail, compared to the first exemplary entry information element 1001 in FIG. 1. FIG. 3 shows a third exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. In FIG. 3, the entry information element 1005 is the same as those in FIG. 1 and FIG. 2 except for a portion of the user group 1003, and the description of the same portion is omitted. In the user group 1003 in FIG. 1, the viewing authority and the editing authority is set for the whole group 1004 representing a collection of one or more users. Also, in the user group 1003 in FIG. 2, the viewing authority and the editing authority are set for each user of the group 1005. On the other hand, in the user group 1003 in FIG. 3, the viewing authority and the editing authority are set for not only the whole group 1005 but also each user of the group 1005. In the user group 1003 in FIG. 3, since the viewing authority and the editing authority can be set for the whole group 1005, it is possible to roughly set access rules. Additionally, since the viewing authority and the editing authority can be set for each user of the group 1005, it is possible to set access rules in detail. Thus, the entry information element 1001 in FIG. 3 makes it easy to set the user group 1003 by setting the viewing authority and the editing authority for the whole group 1005. In addition, the entry information element 1001 in FIG. 3 makes it possible to set access rules in detail by setting the viewing authority and the editing authority for each user of the group 1005. Here, when the entry information element 1001 in FIG. 3 is used, it is necessary to set access rules in the user group 1003 in advance for cases where the first viewing and editing authority set for the whole group 1005 is inconsistent with the second viewing and editing authority set for each user of the group 1005. In these cases, the access rules may be defined to take OR between the first viewing and editing authority and the second viewing and editing authority. In another embodiment, the access rules may be defined to take AND between the first viewing and editing authority and the second viewing and editing authority. In another embodiment, the access rules may be defined in such a way that the first viewing and editing authority has priority over the second viewing and editing authority vice versa. FIG. 4 shows a fourth exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. In the following, the description of the same parts as those of FIG. 1 through FIG. 3 is omitted.

Also, in the entry information element 1001, user groups 1003 a through 1003 c are provided to the entry information portions 1001 b through 1001 d, respectively. In other words, access rules to restrict user's manipulation on the entry information element 1001 can be defined for each information item portion (for each of the entry information portions 1001 a through 1001 d in the illustration of FIG. 4) classified based on kinds of the individual items of the entry information element 1001. FIG. 5 shows a fifth exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. In the following, the description of the same parts as those shown in FIG. 1 through FIG. 4 is omitted. Referring to FIG. 5, entry information portions 1001 a and 1001 e represent information on a single user of a multifunctional product according to the first embodiment. Specifically, the entry information portion 1001 a includes items such as a serial number, an owner ID, and an owner group 1002. Also, the entry information portion 1001 e includes items such as a registration number, a name, an email address, a FAX number, an SMB/FTP name, a password, an SMB/FTP password, a user name, use restriction information, charge data and respective user groups 1003 a through 1003 j. In the user groups 1003 a through 1003 j, a user having manipulation authority on each item of the entry information portion 1001 e is registered. For example, a user registered in the user group 1003 a is allowed to view and edit the item �registration number� of the entry information portion 1001 e corresponding to granted manipulation authority on the item �registration number�. In the entry information 1001 shown in FIG. 5, the owner group 1002 is set for the entry information portion 1001 a. Also, the user groups 1003 a through 1003 j are set for each item of the entry information portion 1001 e of the entry information element 1001 shown in FIG. 5. In other words, access rules to restrict user's manipulation on the entry information element 1001 can be set for each item of the entry information portion 1001 e of the entry information element 1001. According to the user groups 1003 and 1003 a through 1003 j shown in FIG. 1 through FIG. 5, access rules are defined from the viewpoint of users. In another embodiment, however, the access rules may be defined from the viewpoint of functions. FIG. 6 shows a sixth exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. The entry information element shown in FIG. 6 is the same as that shown in FIG. 1 except for a portion of the user group 1003, and the description of the same parts is omitted. The user group 1003 includes a group 1003 k of users having viewing authority on the entry information element 1001, a group 1003 l of users having editing authority on the entry information element 1001, and a group 1003 m of users having deleting authority on the entry information element 1001. A user registered in the group 1003 k is allowed to perform a viewing manipulation on the entry information element 1001. A user registered in the group 1003 l is allowed to perform an editing manipulation on the entry information element 1. A user registered in the group 1003 m is allowed to perform a deleting manipulation on the entry information element 1001. In the entry information element 1001 shown in FIG. 6, an owner group 1002 and a user group 1003 are set for the whole entry information element 1001. Also, the user group 1003 shown in FIG. 6 is not set from the viewpoint of users. In other words, the groups 1003 k through 1003 m are set from the viewpoint of functions. Thus, if the groups 1003 k through 1003 m are defined, function-based access rules can be also reused for another entry information element 1001. As a result, it is possible to register the user group 1003 more efficiently. The same discussion with reference to FIG. 2 through FIG. 5 can be also applied to the entry information 1001 and the user group 1003 shown in FIG. 6. According to the user groups 1003 and 1003 a through 1003 m shown in FIG. 1 through FIG. 6, manipulation authority on the entry information element 1001 and the entry information portions 1001 a through 1001 e can be set for each of the groups 1004 and 1005 composed of a single user or a collection of users. In another embodiment, however, the manipulation authority can be set for all users. If the manipulation authority on the entry information element 1001 and the entry information portions 1001 a through 1001 e can be set for all the users, a smaller data capacity has only to be used to register all the users in the user groups 1003 and 1003 a through 1003 j. As a result, it is possible to save the memory capacity of the multifunctional product. Exemplary structure and operation of a multifunctional product as an embodiment of an information processing apparatus to implement an entry information management method according to the present invention are described with reference to FIG. 7 and FIG. 8.

Here, the platform 1040 is configured to have an application interface (API) 1053 that enables process requests to be received from the applications 1030 by using a predefined function. OS executes software items of the application set 1030 and the platform 1040 as processes in parallel. UCS 1051 stores user information in a storage device such as HDD (Hard Disk Drive), and manages the stored user information. For example, UCS 1051 stores an entry information element 1001 in a storage device such as HDD, and manages the stored entry information element 1001. CCS 1052 provides certification services to the application set 1030. The handler layer 1043 includes a FAX control unit handler (FCUH) 1054 that manages a FAX control unit (FCU), and an image memory handler (IMH) 1055 that allocates processes to memory areas and manages the allocated memory areas. By using an engine I/F 1056 that enables process requests for the hardware resources to be transmitted by means of a predefined function, SRM 1042 and FCUH 1054 issue the process requests for the hardware resources. In the platform 1040, the multifunctional product 1010 can collectively perform processes that individual applications require in common. For example, Japanese Laid-Open Patent Application No. 2002-084383 discloses the functional structure of the multifunctional product 1001 shown in FIG. 7 in detail.

In the entry information element 1001 shown in FIG. 1 through FIG. 6, permission or denial of viewing manipulation and editing manipulation on the entry information element 1001 is set for each user or each group 1004 and 1005. Thus, an address book displayed on the operation panel 1080 can be restricted as follows. FIGS. 31A and 31B show an exemplary entry information element on a user having viewing authority or editing authority and an exemplary entry information element on a user that does not have either viewing authority or editing authority. FIG. 31A shows an exemplary entry information element on the user �Taro Ricoh� of the registration number �00012� wherein the user has viewing authority or editing authority. FIG. 31B shows an exemplary entry information element on the user �Taro Ricoh� of the registration number �00012� wherein the user does not have the viewing authority or the editing authority. FIG. 32 is a diagram for explaining a procedure of displaying an address book according to the first embodiment. For example, the user �Taro Ricoh� of the registration number �00012� inputs a user name and a password in a login screen 1700 displayed on the operation panel 1080. A screen 1710 shows the user name and the password has been supplied by the user �Taro Ricoh� of the registration number �00012� via the screen 1700. When an �EXECUTE� button 1711 in the screen 1710 is pushed, the multifunctional product 1010 selects an entry information element 1001 from an address book, shown in FIG. 31A, over which the user �Taro Ricoh� of the registration number �00012� has viewing authority or editing authority. The entry information element 1001 can be selected by selecting a user group including the user �Ricoh Taro� of the registration number �00012�. When an application that makes use of the entry information 1001 (for example, the scanner application 1034) is selected, the multifunctional product 1010 displays a screen 1720 including the entry information element 1001 in FIG. 31A as a destination on the operation panel 1080. In this manner, the multifunctional product 1010 can display only entry information items over which a logging-in user has viewing authority or editing authority on the operation panel 1080. In the above, the procedure of creating the entry information element 1001 has been described with reference to exemplary screens displayed on the operation panel 1080. In the following, the procedure of creating the entry information element 1001 is described with reference to a sequence diagram shown in FIG. 33. The procedure of creating the entry information element 1001 is described with reference to the screens 1100 through 1280. FIG. 33 is a sequence diagram of an exemplary procedure of creating an entry information element according to the first embodiment. It is supposed that the multifunctional product 1010 first has used the screens 1100 through 1120 to authenticate a user and determines that the logging-in user is a user administrator. At step S1001, CCS 1052 of the multifunctional product 1010 supplies to SCS 1044 a ticket to prove that the logging-in user has been authenticated as a user administrator. At step S1002, SCS 1044 creates the screen 1130. At step S1003, SCS 1044 issues a screen displaying request to OCS 1047. At step S1004, the user administrator performs a key input operation by pushing the �SYSTEM INITIAL SETTING� button 1131 in the screen 1130. OCS 1047 supplies contents of the key input operation to SCS 1044. At step S1005, SCS 1044 creates the screen 1140. At step S1006, SCS 1044 issues a screen displaying request to OCS 1047. In the following, the screens 1150 and 1160 are similarly displayed on the operation panel 1080. At step S1007, SCS 1044 issues an address book search request together with the ticket to UCS 1051. At step S1008, UCS 1051 creates an address book cache for the logging-in user administrator. At step S1009, UCS 1051 supplies the created address book list to SCS 1044. At step S1010, SCS 1044 creates an address book list screen. At step S1011, SCS 1044 issues a screen displaying request to OCS 1047. At step S1012, the user administrator performs a key input operation by pushing one or more entry buttons included in the address book list or the �NEW REGISTRATION� button 1162. Now, it is supposed that the �NEW REGISTRATION� button 1612 has been pushed. OCS 1047 supplies contents of the key input operation to SCS 1044. At step S1013, SCS 1044 creates the screen 1170. At step S1014, SCS 1044 issues a screen displaying request to OCS 1047. In the following, the screens 1180 through 1260 are similarly displayed on the operation panel 1080. Then, when the �SET� button 1261 in the screen 1260 is pushed, SCS 1044 proceeds to step S1015, and generates address book data to register user information supplied via the screens 1170 through 1250 in the address book. At step S1016, SCS 1044 can create the entry information element 1001 by using the generated address book data to issue a registration request to UCS 1051. Here, there is a case where even a user registered in the owner group 1002 is not allowed to delete a user registered in the user group 1003. For example, while such a user registered in a user group 1003 logins the multifunctional product 1010, the user cannot be deleted from the user group 1003. Also, for example, during login of a user registered in the user group 1003, edited contents of the entry information element 1001 on the user is not reflected until the user logins the multifunctional product 1010 at the next time. In addition, an entry information element 1001 on a user that temporarily makes use of a copier function (hereinafter which is referred to as a guest user) is configured as shown in FIG. 34. FIG. 34 shows a seventh exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. Since a guest user is to simply use the multifunctional product 1010, it is unnecessary to set an email address and a FAX number for the guest user. Thus, the entry information element 1001 shown in FIG. 34 includes only an owner ID, an owner group 1002, user groups 1003 a through 1003 c, a registration number, a name, a user name and use restriction information. Such a guest user is not registered in the owner group 1002. Also, since the guest user is not registered in the user group 1003 a, the guest user is not allowed to view and edit entry information elements 1001 on other users. However, since the guest user is allowed to view the user group 1003 c, the guest user can check the use restriction information. Here, manipulation corresponding to the above-mentioned viewing authority �R� and editing authority �W� may be fixed. Alternatively, the manipulation may be changeable as follows. FIG. 35 shows a table representing an exemplary policy to define manipulations corresponding to various kinds of authority. In FIG. 35, a policy corresponding to a case where viewing authority and editing authority are included in manipulation authority is illustrated. For example, �view name and registration number� and �refer� operations are defined as manipulations corresponding to the viewing authority �R� in accordance with the policy shown in FIG. 35. Also, �view name and registration number�, �refer�, and �change� operations are defined as manipulations corresponding to the editing authority �w�. In the policy shown in FIG. 35, a user having the viewing authority �R� can perform the �view name and registration number� and �refer� operations. Also, a user having the editing authority �W� can perform the �view name and registration number�, �refer� and �change� operations. If the policy shown in FIG. 35 is changed, it is possible to change manipulations corresponding to various kinds of authority. A variation of a multifunctional product according to the first embodiment is described. In the first embodiment, the owner group 1002 and the user group 1003 are separately set. However, it is possible to set owner authority to a user by using a policy shown in FIG. 36. FIG. 36 shows a table representing an exemplary policy allowed to set owner authority to a user. In the policy shown in FIG. 36, in addition to the policy shown in FIG. 35, �view name and registration number� and �delete entry� operations are defined as a manipulation corresponding to the deleting authority �D�. In addition, �view name and registration number�, �refer�, �change� and �delete entry� operations are defined as manipulations corresponding to full control authority �O�. Also, new authority �new role� may be defined in the policy shown in FIG. 36. The manipulation authority is composed of the viewing authority, the editing authority and the deleting authority. The full control authority includes the editing authority. For example, in the policy shown in FIG. 36, it is sufficient that the full control authority �O� is provided to only a user that sets owner authority. Such a user having the owner authority has authority equivalent to authority set in the above-mentioned owner group 1002. FIG. 37 shows an eighth exemplary data structure of an entry information element of a multifunctional product according to the first embodiment. The entry information element 1001 shown in FIG. 37 is the same as the entry information element 1001 shown in FIG. 4 except for a portion thereof, and the description thereof is omitted.

The entry information portion 1001 d includes items such as a user name, use restriction information, charge data and a user list 1006 c. The user list 1006 a includes users having manipulation authority on the entry information portion 1001 g. A user registered in the user list 1006 a can perform manipulations on the entry information portion 1001 g depending on the manipulation authority on the entry information portion 1001 g. Also, the user list 1006 b includes users having manipulation authority on the entry information portion 1001 h. A user registered in the user list 1006 b can perform manipulations on the entry information portion 1001 h depending on the manipulation authority on the entry information portion 1001 h. The user list 1006 c includes users having manipulation authority on the entry information portion 1001 i. A user registered in the user list 1006 c can perform manipulations on the entry information portion 1001 i depending on the manipulation authority on the entry information portion 1001 i. Among users registered in the user lists 1006 a through 1006 c, a user having the full control authority has setting authority on the user lists 1006 a through 1006 c. In other words, the user having the full control authority has the owner authority. In the entry information element 1001 shown in FIG. 37, users having the owner authority and users having manipulation authority are set for the individual entry information portions 1001 g through 1001 i. In other words, in the entry information element 1001, an access rule to restrict user's manipulation on the entry information element 1001 can be defined for each portion (each of the entry information portions 1001 g through 1001 i in FIG. 37) classified based on item types of the entry information element 1001. A method of setting owner authority for a user by using the policy as shown in FIG. 36 can be applied to an entry information element 1001 other than the above-mentioned entry information element 1001 shown in FIG. 6. If the policy shown in FIG. 36 is used, the viewing authority, the editing authority, the editing/deleting authority or the full control authority can be set via a screen 1800 as shown in FIG. 38 for a user, a group composed of one or more users, or all users.

The charge means corresponds to the charge module 3071. Thus, in the certification and charge setting table 3201, a certification module 3070 and a charge module 3071 can be set for each application. For example, in the certification and charge setting table 3201 shown in FIG. 50, a certification module A is set as certification means of the copier application 3042, and a charge module I is set as charge means of the copier application 3042. Also, in the certification and charge setting table 3201 shown in FIG. 50, a certification module B or (+) C is set as certification means of the FAX application 3043, and a charge module III is set as charge means of the FAX application 3043. In addition, in the certification and charge setting table 3201, certification modules A and (*) C are set as certification means of the scanner application 3044, and a charge module II is set as charge means of the scanner application 3044. In this manner, in the certification and charge setting table 3201, conjunction (AND) and disjunction (OR) of a plurality of certification modules 3070 can be set as certification means. Here, although not illustrated in the certification and charge setting table 3201 in FIG. 50, conjunction (AND) or disjunction (OR) of a plurality of charge modules 3071 can be set as charge means. MCS 3066 manages a stored document database (DB) 3203. UCS 3067 manages an address book table 3202. The address book table 3202 has an entry information element on a single user as illustrated in FIG. 51. FIG. 51 shows an exemplary data structure of an entry information element of the multifunctional product 3001 according to the second embodiment. An entry information element 3230 represents information on a user of the multifunctional product 3001. The entry information 3230 is classified into entry information portions 3230 a through 3230 d. The entry information portion 3230 a includes a serial number and an owner ID as items. The entry information portion 3230 b includes items such as a registration number, a name, an email address, a FAX number, an SMB/FTP name, and a user list 3231 a. The entry information portion 3230 c includes items such as a password, an SMB/FTP password and a user list 3231 b. The entry information portion 3230 d includes items such as a user name, user restriction information, charge data and a user list 2231 c. In the user list 3231 a, a user having manipulation authority on the entry information portion 3230 b is registered. In the user list 3231 b, a user having manipulation authority on the entry information portion 3230 c is registered. In the user list 3231 c, a user having manipulation authority on the entry information portion 3230 d is registered. In the user lists 3231 a through 3231 c, viewing authority �R�, editing authority �W�, deleting authority �D� and owner authority �O� are set as the manipulation authority on the entry information portions 3230 b through 3230 d. Also, in the use restriction information in the entry information 3230, for example, permission or denial of monochrome copying, permission of two-color copying, permission of full-color copying, permission of monochrome printing, permission of single-color printing, permission of two-color printing, permission of full-color printing, permission of FAX transmission, permission of scanner reading, permission of document box printing, permission of network access and permission of other operations are set. Next, an exemplary procedure of adding a certification module 3070 and a charge module 3071 from the SD card 3204 is described. For example, when receiving a request to display a user certification management screen for registering a certification module 3070 and a charge module 3071 from a user, the multifunctional product 3001 displays a user certification management screen 3250 or 3260 on the operation panel 3120. FIG. 52 shows an exemplary user certification management screen according to the second embodiment. The user certification management screen 3250 corresponds to a case where the certification module 3070 and the charge module 3071 are not included in the SD card 3204. Thus, the user certification and management screen 3250 is displayed in a status where a (thinner colored) �ADDITIONAL CERTIFICATION� button 3251 to use the certification module 3070 and the charge module 3071 added from the SD card 3204 cannot be selected. On the other hand, the user certification management screen 3260 corresponds to a case where the certification module 3070 and the charge module 3071 are included in the SD card 2204. When CCS 3068 detects a certification module 3070 and a charge module 3071 from a directory (for example, root/ccs/option) of the SD card 3204 at activation time, CCS 3068 adds the certification module 3070 and the charge module 3071 from the SD card 3204. Thus, the user certification and management screen 3260 is displayed in a status where an �ADDITIONAL CERTIFICATION� button 3261 to use the certification module 3070 and the charge module 3071 added from the SD card 2204 can be selected. When a user selects the �ADDITIONAL CERTIFICATION� button 3261, a certification manner and a charge manner corresponding to the added certification module 3070 and the charge module 3071, respectively, from the SD card 3204 are displayed in the user certification management screen 3260. For example, IC card certification and fingerprint certification manners are displayed as embodiments of the certification manners in the user certification management screen 3260 in FIG. 52. In the user certification management screen 3260, a certification device and a charge device corresponding to the certification module 3070 and the charge module 3071 added from the SD card 3204 may be displayed. A user can use the user certification management screen 3260 to select a certification manner and a charge manner. When the user pushes a �NEXT� button 3262, a user certification management screen 3270 is displayed in the operation panel 3120. In the user certification management screen 3270, various functions (management contents) to select a certification manner and a charge manner are displayed. The user can use the user certification management screen 3270 to select functions to designate a certification manner and a charge manner. Next, an exemplary procedure of creating a certification and charge setting table 3201 shown in FIG. 50 is described. For example, after the multifunctional product 3001 starts the application set 3040 and the platform 3050, a copying screen 3300 as illustrated in FIG. 53 is displayed in the operation panel 3120. FIG. 53 and FIG. 54 show a series of exemplary screens displayed in the operation panel 3120. When a user pushes an �INITIAL SETTING� button 3301 in the screen 3300, the multifunctional product 3001 displays an initial setting screen 3310 on the operation panel 3120. When the user a �SYSTEM INITIAL SETTING� button 3311 in the screen 3310, the multifunctional product 3001 displays an initial system setting screen 3320 on the operation panel 3120. When the user pushes an �ADMINISTRATOR SETTING� button 3321 in the screen 3320, the multifunctional product 3001 displays an administrator setting screen 3330 as illustrated in FIG. 54 on the operation panel 3120. The user can use screens 3340, 3350 and 3360, to which the user can move from the screen 3330, to create a certification and charge setting table 3201. When the user pushes a �MANAGE USER CODE� button 3331 in the screen 3330, the multifunctional product 3001 displays a screen 3340 for setting user code management as certification means and charge means of the applications 3040 on the operation panel 3120. When the user pushes a �MANAGE KEY COUNTER� button 3332 in the screen 3330, the multifunctional product 3001 displays a screen 3350 for setting key counter management as certification means and charge means of the applications 3040 on the operation panel 3120. When the user pushes a �MANAGE EXTERNAL CHARGE DEVICE� button 3333 in the screen 3330, the multifunctional product 3001 displays a screen 3360 for setting external charge device management as certification means and charge means of the applications 3040 on the operation panel 3120. If the user uses the screens 3340, 3350 and 3360 to select a plurality of certification means and charge means for one of the applications 3040, conjunction (AND) and disjunction (OR) can be set in the certification and charge setting table 3201 shown in FIG. 50. In the above, the series of screens corresponding to the procedure of creating the certification and charge setting table 3201 displayed on the operation panel 3120 have been described. The screens 3300 through 3360 are displayed on the operation panel 3120 by OCS 3063. Here, SCS 3069 requests OCS 3063 to display the screens 3300 through 3360. When one of the application set 3040, for which certification means and charge means are set in the certification and charge setting table 3201, is driven, a certification screen as described in detail below is displayed on the operation panel 3120. In the following, an example of starting the copier application 3042 is described. FIG. 55 shows an exemplary certification screen corresponding to a case where management via user codes is set as certification means and charge means of the copy application 3042. A certification screen 3400 shown in FIG. 55 includes an input space 3401 for inputting a user code and a message to prompt a user to input a user code. When the user inputs a user code in the input space 3401 and pushes �#� button 3402, the multifunctional product 3001 displays a copying screen 3300 on the operation panel 3120. FIG. 56 shows an exemplary certification screen corresponding to a case where management via a coin rack is set as certification means and charge means of the copier application. A certification screen 3410 shown in FIG. 56 includes a message to prompt the user to supply money in the coin rack 3207. When the user supplies a specified mount of money in the coin rack 3207, the multifunctional product 3001 performs certification as described below. If the certification is successfully completed, the copying screen 3300 is displayed on the operation panel 3120 of the multifunctional product 3001. FIG. 57 shows an exemplary certification screen corresponding to a case where management using a plurality of means is set as certification means and charge means of the copier application. Screens 3420 and 3430 include buttons to select a key counter, a keycard, a user code, user certification, an IC card 3205 and fingerprint certification, provided in the certification and charge setting table 3201 as certification means and charge means of the copier application. Here, when the user pushes a button 3421 during displaying of the screen 3420 on the operation panel 3120, the multifunctional product 3001 displays a screen 3430 on the operation panel 3120. On the other hand, when the user pushes a button 3431 during displaying of the screen 3430 on the operation panel 3120, the multifunctional product 3001 displays a screen 3420 on the operation panel 3120. For example, when the user pushes a button to select a user code in the screen 3420, a certification screen 3440 corresponding to a case where management via a user code is set is displayed on the operation panel 3120 of the multifunctional product 3001. Also, when the user pushes a button to select a key counter in the screen 3420, a certification screen 3450 corresponding to a case where management via a key counter is set is displayed on the operation panel 3120 of the multifunctional product 3001. When the certification is successfully completed as described above, the copying screen 3300 is displayed on the operation panel 3120 of the multifunctional product 3001. In the certification screen shown in FIG. 57, if certification corresponding to one of a plurality of means registered in the certification and charge setting table 3201 as certification means and charge means is successfully completed, the copying screen 3300 is displayed on the operation panel 3120. In this case, disjunction (OR) of the plurality of certification modules 3070 is set as certification means in the certification and charge setting table 3201. FIG. 58 shows an exemplary certification screen corresponding to a case where management using a plurality of means is set as certification means and charge means of the copier application. Screens 3460 and 3470 include buttons to select a user code, a key counter, a keycard and fingerprint certification provided in the certification and charge setting table 3201 as certification means and charge means of the copier application. In the screens 3460 and 3470, if certification of the user is not successfully completed by using a user code and one of a key counter, a keycard and fingerprint certification, the copying screen 3300 cannot be displayed on the operation panel 3120. Here, when the user pushes a button 3461 during displaying of the screen 3460 on the operation panel 3120, the multifunctional product 3001 displays the screen 3470 on the operation panel 3120. On the other hand, when the user pushes a button 3471 during displaying of the screen 3470 on the operation panel 3120, the multifunctional product 3001 displays the screen 3460 on the operation panel 3120. For example, when the user pushes a button to select a keycard in the screen 3460, a certification screen (not illustrated) corresponding to a case where management via the keycard is set is displayed on the operation panel 3120 of the multifunctional product 3001. If the certification via the keycard is successfully completed, a screen 3480 having a button to select a user code or a key counter is displayed on the operation panel 3120 of the multifunctional product 3001. When the user pushes a button to select a user code in the screen 3480, a certification screen 3500 corresponding to a case where management via the user code is set is displayed on the operation panel 3120 of the multifunctional product 3001. If the certification using the user code is successfully completed, the copying screen 3300 is displayed on the operation panel 3120 of the multifunctional product 3001. Also, when the user pushes a button to select a user code in the screen 3460, a certification screen (not illustrated) corresponding to a case where management via the user code is set is displayed on the operation panel 3120 of the multifunctional product 3001. If the certification using the user code is successfully completed, a screen 3490 having a button to select a key counter or a keycard is displayed on the operation panel 3120 of the multifunctional product 3001. When the user pushes the button to select a key counter or a keycard in the screen 3490, a certification screen (not illustrated) corresponding to a case where management via the key counter or the keycard is set is displayed on the operation panel 3120 of the multifunctional product 3001. If the certification using the key counter or the keycard is successfully completed, the copying screen 3300 is displayed on the operation panel 3120 of the multifunctional product 3001. As mentioned above, if the certification using a user code and one of a key counter, a keycard and fingerprint certification is successfully completed, the copying screen 3300 is displayed on the operation panel 3120 of the multifunctional product 3001. In the certification screen shown in FIG. 58, if the certification using a predefined combination of a plurality of means registered in the certification and charge setting table 3201 as certification means and charge means is successfully completed, the copying screen 3300 is displayed on the operation panel 3120. In this case, conjunction (AND) of the plurality of certification modules 3070 is set as certification means in the certification and charge setting table 3201. Next, an exemplary operation of the multifunctional product 3001 to which a certification module 3070 and a charge module 3071 are added depending on addition of certification means and charge means, focused on an operation of the certification module 3070 and the charge module 3071, is described. FIG. 59 is a sequence diagram of an exemplary operation of a certification module and a charge module according to the second embodiment. For example, when the application set 3040 and the platform 3050 are activated, the certification module 3070 and the charge module 3071 of the multifunctional product 3001 proceed to step S3001. In FIG. 59, the certification module 3070 and the charge module 3071 are represented as �CCM-A� and �CCM-B�, respectively. At step S3001, CCM-A registers the certification module 3070 or the charge module 3071 (hereinafter which are collectively referred to as certification charge modules) in CCS 3068. At step S3002, CCM-A registers the type of certification means or charge means corresponding to the certification charge modules (for example, coin rack 3207) as the type of certification and charge devices in CCS 3068. At step S3003, CCM-A reports the status of the certification charge modules to CCS 3068. At step S3004, CCM-B registers certification charge modules in CCS 3068. At step S3005, CCM-B registers the type of certification means and charge means corresponding to the certification charge modules as the type of certification and charge devices in CCS 3068. At step S3006, CCM-B reports the status of the certification charge modules to CCS 3068. The operation of steps S3001 through S3003 and steps S3004 through S3006 is performed on all certification modules 3070 and charge modules 3071 of CCS 3068. At step S3007, the copier application 3042 performs application registration on SCS 3069. At step S3008, SCS 3069 sends to the copier application 3042 a system setting report indicating that use restriction is provided with the copier application 3042. If the copier application 3042 has use restriction based on the system setting report at step S3008, the copier application 3042 performs certification registration on CCS 3068 at step S3009. At step S3010, CCS 3068 requests SCS 3069 to acquire the certification and charge setting table 3201. At step S3011, SCS 3069 supplies the certification and charge setting table 3201 to CCS 3068. At step S3012, CCS 3068 identifies a certification charge module set as certification means or charge means of the copier application 3042 with reference to the certification and charge setting table 3201, and supplies contents thereof as a certification setting report to the copier application 3042. For example, in the certification and charge setting table 3201 shown in FIG. 50, CCS 3068 identifies the certification means A and the charge means I set as the certification means and the charge means of the copier application 3042, and supplies the contents thereof as a certification setting report to the copier application 3042. At step S3013, CCS 3068 reports the certification status to the copier application 3042. Through the certification status report, the certification status (for example, the status where the use is restricted) of the certification charge module identified at step S3012 is reported. For example, if the copying screen 3300 is displayed on the operation panel 3120, the copier application 3042 requests CCS 3068 to display a certification screen. At step S3015, CCS 3068 issues a certification screen display report corresponding to the certification means of the copier application 3042. For example, CCS 3068 issues a certification screen display report corresponding to the certification means A set as the certification means of the copier application 3042. At step S3016, SCS 3069 issues an operation part owner transition request to the copier application 3042. At step S3017, the copier application 3042 issues an operation part owner transition response to SCS 3069. Through the operation of steps S3016 and S3017, an owner of the operation part of the multifunctional product 3001 is switched into the copier application 3042. At step S3018, SCS 3069 issues a certification screen display preparing request to CCS 3068. At step S3019, CCS 3068 issues a certification charge module screen preparing request to the certification means of the copier application 3042. For example, CCS 3068 issues the certification charge module screen preparing request to CCM-A set as the certification means of the copier application 3042. At step S3020, CCM-A set as the certification means of the copier application 3042 creates a screen for the certification charge module screen such as screens 3400 and 3410. At step S3021, CCM-A informs CCS 3068 that the certification charge module screen has been prepared. At step S3022, CCS 3068 informs SCS 3069 that the displaying of the certification screen has been prepared. At step S3023, SCS 3069 displays the certification charge module screen on the operation panel 3120 by requesting OCS 3063 to display the certification charge module screen created at step S3020. In the multifunctional product 3001, the certification module 3070 or the charge module 3071 manages the certification charge module screen, and SCS 3069 manages a screen to select the certification charge module screen (for example, the screens 3420 and 3430). According to the sequence diagram shown in FIG. 59, the certification module 3070 creates the certification charge module screen displayed on the operation panel 3120. As a result, programs of SCS 3069 do not have to be modified in response to addition of the certification charge module. Also, the certification charge module performs registration on CCS 3068 as at steps S3001 through S3006 in the sequence diagram shown in FIG. 59. As a result, it is unnecessary to modify the programs of SCS 3069 in response to the addition of the certification charge module. In this manner, the multifunctional product 3001 according to the second embodiment makes it easier to add a new certification function and a new charge function. Next, an exemplary operation to cancel use restriction of the application set 3040 via certification screens is described. FIG. 60 is a sequence diagram of a first exemplary user restriction cancel operation of a multifunctional product according to the second embodiment. In the sequence diagram shown in FIG. 60, steps S3001 through S3013 in FIG. 59 prior to step S3031 are omitted. At step S3031, the copier application 3042 requests CCS 3068 to display a certification screen. At step S3032, CCS 3068 causes the certification module 3070 to create a certification screen corresponding to certification means of the copier application 3042. At step S3033, CCS 3068 issues a use restriction screen report. At step S3034, SCS 3069 displays the certification screen on the operation panel 3120 by requesting OCS 3063 to display the certification screen created at step S3032. In the following, an example of setting user certification as the certification means of the copier application 3042 is described. In response to the screen displaying request at step S3034, a certification screen for user certification is displayed on the operation panel 3120. When a user inputs a user name and a password in the certification screen for the purpose of the user certification, OCS 3063 reports a key event to SCS 3069 at step S3035. At step S3036, SCS 3069 reports the key event to CCS 3068. At step S3037, CCS 3068 converts the reported key event into the user name and the password. At step S3038, CCS 3068 requests UCS 3067 to authenticate the user name and the password. At step S3039, UCS 3067 compares the user name and the password supplied from CCS 3068 with contents in an address book table 3202. At step S3040, UCS 3067 sends the certification result at step S3039 as a certification result response to CCS 3068. At step S3041, CCS 3068 checks use restriction set in the certification and charge setting table 3201. In the following, an example of cancelling use restriction of the copier application 3042 based on the check result at step S3041 is described. At step S3042, CCS 3068 informs the copier application 3042 that the use restriction is to be cancelled based on the certification status report. At step S3043, CCS 3068 supplies to the copier application 3042 a ticket representing that the user has been authenticated. This ticket includes an expiration date, acquisition date and time, an encryption key for encrypting the ticket, user information, and a digest message (DM) of the whole ticket. The user information includes a user name, a password, an entry ID, use restriction information, and local/remote operation identification information, for example. The copier application 3042 having the ticket is allowed to use various services provided by individual processes. Also, the digest message of the whole ticket is used to detect falsification of the ticket. At step S3044, CCS 3068 supplies login user information to SCS 3069. The login information rather than the ticket is supplied to SCS 3069, because the certification is required again by items of system initial setting. When receiving the ticket, the copier application 3042 requests CCS 3068 to display a certification screen to delete a certification screen at step S3045. At step S3026, CCS 3068 requests SCS 3069 to display the certification screen to delete the certification screen. At step S3047, SCS 3069 displays the copying screen 3300 on the operation panel 3120 by requesting OCS 3063 to display the copying screen 3300. In other words, when the use restriction of the copier application 3042 is cancelled, the copying screen 3300 can be displayed on the operation panel 3120. As a result, the user can make use of function provided by the copier application 3042. FIG. 61 is a sequence diagram of a second exemplary use restriction cancel operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 61, steps S3001 through S3013 in FIG. 59 prior to step S3051 are omitted as in FIG. 60. Also, steps S3051 through S3057 are similar to steps S3031 through S3037 in FIG. 60, and the description thereof is omitted. At step S3058, CCS 3068 uses the user name converted at step S3057 to issue an entry ID acquisition request. At step S3059, UCS 3067 searches an address book table 3202 by using the user ID supplied from CCS 3068 as key information, and reads an entry ID corresponding to the user ID. CCS 3068 acquires the entry ID read from the address book table 2202 from UCS 3067. At step S3060, CCS 3068 uses the entry ID acquired from UCS 3067 to issue a password acquisition request. At step S3061, UCS 3067 searches the address book table 3202 by using the entry ID supplied from CCS 3068 as key information, and reads a password corresponding to the entry ID. The read password is supplied from UCS 3067 to CCS 3068. At step S3062, CCS 3068 performs certification by comparing the password converted at step S3057 with the password supplied from UCS 3067. If the certification is successfully completed, CCS 3068 uses the entry ID acquired from UCS 3067 to issue a restriction information acquisition request at step S3063. At step S3064, UCS 3067 searches the address book table 3202 by using the entry ID supplied from CCS 3068 as key information, and reads restriction information corresponding to the entry ID. At step S3065, UCS 3067 sends the restriction information read at step S3064 as a certification result response to CCS 3068. For example, based upon the certification result response at step S3065, the use restriction of the copier application 3042 is cancelled. Here, steps S3066 through S3071 in FIG. 61 are similar to steps S3042 through S3047 in FIG. 60, and the description thereof is omitted. In this manner, if the user restriction of the copier application 3042 is cancelled, the copying screen 3300 is displayed on the operation panel 3120. As a result, the user can make use of functions provided by the copier application 3042. FIG. 62 is a sequence diagram of a third exemplary use restriction cancel operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 62, steps S3001 through S3013 prior to step S3081 are omitted as in FIG. 60. Also, steps S3081 through S3083 in FIG. 62 are similar to steps S3031 through S3033 in FIG. 60, and the description thereof is omitted. At step S3084, SCS 3069 displays a certification screen on the operation panel 3120 by requesting OCS 3063 to display the certification screen created at step S3082. In the following, an example of using the IC card 3205 as the certification means of the copier application 3042 is described. In response to the screen displaying request at step S3084, a certification screen for IC card certification is displayed. When the user inserts the IC card 3205 in the card reader 3204, the card reader 3204, which is an embodiment of an external certification device, performs certification by comparing information recorded in the IC card 3205 with information recorded in an address book of the card reader 3204. At step S3086, the card reader 3204 sends the certification result at step S3085 as a certification status report to SCS 3069. At step S3087, SCS 3069 sends an external charge status report to CCS 3068 based on the certification status report received at step S3086. Here, steps S3088 through S3094 in FIG. 62 are similar to steps S3041 through S3047 in FIG. 60, and the description thereof is omitted. In this manner, if the use restriction of the copier application 3042 is cancelled, the copying screen is displayed on the operation panel 3120. As a result, the user can make use of functions provided by the copier application 3042. FIG. 63 is a sequence diagram of a fourth exemplary use restriction cancel operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 63, steps S3001 through S3013 prior to step S3100 are omitted as in FIG. 60. Also, steps S3100 through S3106 are similar to steps S3081 through S3087, and the description thereof is omitted. At step S3107, CCS 3068 acquires information required to search the address book table 3202 from the external charge status report received from SCS 3069 at step S3106. At step S3108, CCS 3068 requests UCS 3067 to start the searching. At step S3109, UCS 3067 searches the address book table 3202 by using information supplied together with the search start request from CCS 3068 as key information, and reads user information corresponding to the information. UCS 3067 sends the read user information as a search completion notice to CCS 3068. At step S3111, CCS 3068 checks use restriction set in the certification and charge setting table 3201 based on the search completion notice received at step S3110. Here, steps S3112 through S3117 in FIG. 63 are similar to steps S3089 through S3094 in FIG. 62, and the description thereof is omitted. In this manner, if the use restriction of the copier application 3042 is cancelled, the copying screen 3300 is displayed on the operation panel 3120. As a result, the user can make use of functions provided by the copier application 3042. Next, exemplary charge operations after the copying screen 3300 is displayed on the operation panel 3120 of the multifunctional product 3001 are described. FIG. 64 is a sequence diagram of a first exemplary charge operation of a multifunctional product according to the second embodiment. At step S3120, OCS 3063 informs SCS 3069 that a user has supplied a start key. At step S3121, SCS 3069 informs the copy application 3042 that the start key has been pushed. In response to receipt of the notice, the copy application 3042 requests CCS 3068 to count charge for the application. At step S3123, the copier application 3042 issues a copying job start request together with a ticket to ECS 3065. At step S3124, ECS 3065 asks CCS 3068 whether the job involved in a sheet size can be executed. At step S3125, CCS 3068 asks SCS 3069 whether the job involved in the sheet size can be executed. At step S3126, SCS 3069 issues an executability (permission or denial of job execution) request including the sheet size to an external charge certification device such as the coin rack 3307. At step S3127, the external charge certification device determines whether the job can be executed based on the sheet size and remaining deposit, and sends an executability response corresponding to the determination result to SCS 3069. At step S3128, SCS 3069 sends the executability response received at step S3127 to CCS 3068. At step S3129, based on the executability response received at step S3128, CCS 3068 sends a job executability result notice to ECS 3065. If the job executability result notice indicates that the job can be executed, ECS 3065 reports process start to the engine part 3122 at step S3130. At step S3131, CCS 3068 receives the status of a plotter process from the engine part 3122. At step S3132, based on the status of the plotter process received from SCS 3069, CCS 3068 requests SCS 3069 to count charge. At step S3133, SCS 3069 issues a charge counting request to the external charge certification device set in the certification and charge setting table 3201 as the charge means of the copy application 3042. In other words, the charge counting operation is performed in the external charge certification device. At step S3134, the plotter process status is supplied from the engine part 3122 to CCS 3068. At step S3136, the plotter process status is supplied from the engine part 3122 to ECS 3065. At step S2315, a process end is supplied from the engine part 3122 to ECS 3065. In response to receipt of the process end, ECS 3065 informs the copier application 3042 that the job has been executed at step S3137. At step S3138, the copy application 3042 requests CCS 3068 to stop counting the application charge. According to the charge operation in FIG. 64, even if copying charge is variable depending on sheet sizes, it is possible to execute a job by checking executability of the job including a sheet size. Specifically, if the current deposit can cover the copying charge corresponding to the sheet size, the job is executed. FIG. 65 is a sequence diagram of a second exemplary charge operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 65, steps S3140 through S3144 are similar to steps S3120 through S3124 in FIG. 64, and the description thereof is omitted. At step S3145, CCS 3068 requests SCS 3069 current remaining deposit. At step S3146, SCS reports the remaining deposit to CCS 3068. Based upon the reported remaining deposit, CCS 3068 determines whether a job can be executed. At step S3147, based on the determination result, CCS 3068 reports the job executability result to ECS 3065. Here, steps S3148 through S3150 are similar to steps S3130 through S3132 in FIG. 64, and the description thereof is omitted. At step S3151, in response to the charge counting request at step S3150, SCS 3069 counts charge. In other words, SCS 3069 rather than the external charge certification device performs the charge counting operation. Here, steps S3152 through S3156 are similar to steps S3134 through S3138 in FIG. 64, and the description thereof is omitted. According to the charge operation in FIG. 65, it is checked whether a job can be executed, and if current deposit sufficiently remains, the job is allowed to be executed. FIG. 66 is a sequence diagram of a third exemplary charge operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 66, steps S3160 through S3170 are similar to steps S3140 through S3150 in FIG. 65, and the description thereof is omitted. At step S3171, SCS 3069 requests an external charge certification device, which is set in the certification and charge setting table 3201 as the charge means of the copy application 3042, to count charge. In other words, the charge counting operation is performed in the external charge certification device. At step S3172, based on current remaining deposit reported by SCS 3069 at step S3166, CCS 3068 checks the remaining deposit. If the remaining deposit is 0, CCS 3068 requests ECS 3065 to stop the job at step S3173. At step S3174, in response to the job stop request, ECS 3065 instructs the engine part 3122 to cancel the process. Here, steps S3175 through S3179 are similar to steps S3153 through S3156 in FIG. 65, and the description thereof is omitted. According to the charge operation in FIG. 66, CCS checks current remaining deposit, and if the deposit is used up, CCS 3068 can stop the job. FIG. 67 is a sequence diagram of a fourth exemplary charge operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 67, steps S3180 through S3193 are similar to steps S3120 through S3133 in FIG. 64, and the description thereof is omitted. At step S3194, if the remaining deposit is 0, the external charge certification device instructs the engine part 3122 to cancel the process. In other words, the external charge certification device stops the process of the engine part 3122. Here, steps S3195 through S3199 are similar to steps S3134 through S3138 in FIG. 64, and the description thereof is omitted. According to the charge operation in FIG. 67, the external charge certification device checks current remaining deposit, and when the deposit is used up, the external charge certification device can stop the job. FIG. 68 is a sequence diagram of a fifth exemplary charge operation of a multifunctional product according to the second embodiment. In the sequence diagram in FIG. 68, steps S3200 through S3211 are similar to steps S3140 through S3151 in FIG. 65, and the description thereof is omitted. At step S3212, if the current remaining deposit is 0, SCS 3069 instructs the engine part 3122 to cancel the process. In other words, SCS 3069 stops the process of the engine part 3122. At step S3213, the engine part 3122 informs ECS 3065 that the process has been stopped. At step S3214, the engine part 3122 reports a plotter process status to CCS 3068. At step S3215, the engine part 3122 reports the plotter process status to ECS 3065. Here, steps S3216 and S3217 are similar to steps S3155 through S3156 in FIG. 65, and the description thereof is omitted. According to the charge operation in FIG. 68, when the deposit is used up, SCS 3069 can stop the job. Although the cases where the use restriction of the application set 3040 is cancelled have been described with reference to FIG. 60 through FIG. 63, the case where the use restriction cannot be cancelled has to be considered. Next, examples where the use restriction of the application set 3040 cannot be cancelled are described. FIG. 69 is a sequence diagram of an exemplary use restriction cancel operation for the case where use restriction is not cancelled. In the sequence diagram in FIG. 69, steps S3001 through S3013 in FIG. 59 prior to step S3220 are omitted as in the sequence diagram in FIG. 60. At step S3220, the FAX application 3043 requests CCS 3068 to display a certification screen. At step S3221, CCS 3068 instructs the certification module 3070 to create a certification screen corresponding to the certification means of the FAX application 3043. At step S3222, CCS 3068 sends a use restriction screen. At step S3223, SCS 3069 displays the certification screen on the operation panel 3120 by requesting OCS 3063 to display the certification screen created at step S3221. In the following, a case where user certification is set as the certification means of the FAX application 3043 is described. In response to the screen displaying request at step S3223, a certification screen to authenticate the user is displayed on the operation panel 3120. Here, steps S3224 through S3229 are similar to steps S3035 through S3040 in FIG. 60, and the description thereof is omitted. At step S3230, CCS 3068 checks use restriction set in the certification and charge setting table 3201. In the following, a case where the use restriction of the FAX application 3043 is not cancelled based on the check result at step S3230 is described. At step S3231, CCS 3068 determines that the use restriction is not cancelled based on the check result at step S3230, and sends login user information to the FAX application 3043. At step S3232, CCS 3068 sends the login user information to SCS 3069. In response to receipt of the login user information, the FAX application 3043 issues a certification screen display request to display a use restriction screen 3510, as illustrated in FIG. 70, on the operation panel 3120 to CCS 3068 at step S3233. FIG. 70 shows an exemplary use restriction screen. The illustrated user restriction screen includes a message indicating that the use of a function is restricted. At step S3234, CCS 3068 creates the use restriction screen 3510. At step S3235, CCS 3068 sends issues a use restriction screen notice to SCS 3069. At step S3236, SCS 3069 displays the use restriction screen 3510 on the operation panel 3120 by requesting OCS 3063 to display the use restriction screen 3510. In other words, if the use restriction of the FAX application 3043 is not cancelled, the use restriction screen 3510 is displayed on the operation panel 3120, and the user cannot make use of functions provided by the FAX application 3043. FIG. 71 is a sequence diagram of another exemplary use restriction canceling operation for the case where use restriction is not cancelled. In the sequence diagram in FIG. 71, steps S3001 through S3013 in FIG. 59 prior to step S3240 are omitted. Also, steps S3240 through S3252 in FIG. 71 are similar to steps S3220 through S3232 in FIG. 69, and the description thereof is omitted. In response to receipt of login user information, the FAX application 3043 creates the use restriction screen 3510, as illustrated in FIG. 70, at step S3253. At step S3254, the FAX application 3043 issues a use restriction screen notice to SCS 3069. At step S3255, SCS 3069 displays the use restriction screen 3510 on the operation panel 3130 by requesting OCS 3063 to display the use restriction screen 3510. In other words, if the use restriction of the FAX application 3043 is not cancelled, the use restriction screen 3510 is displayed on the operation panel 3120, and the user cannot make use of functions provided by the FAX application 3043. It is noted that the FAX application 3043 creates the use restriction screen 3510 in accordance with the sequence diagram in FIG. 71. Although some of the application set 3040 that use an operation part such as the operation panel 3120 of the multifunctional product 3001 are used to describe the above operations with respect to FIG. 60 through FIG. 63, another application 3040 remotely operated by a computer 3210 connected via the network 3220 may be used. FIG. 72 is a sequence diagram of another exemplary use restriction cancel operation through remote manipulation according to the second embodiment. In FIG. 72, certification is performed at a network protocol level. At step S3260, an external computer 3210 issues a connection request to NCS 3061. This connection request includes a user name and a password. At step S3261, NCS 3061 requests CCS 3068 to authenticate a user by providing the user name and the password as an argument. At step S3262, CCS 3068 converts the certification request into the user name and the password. At step S3263, CCS 3068 requests UCS 3067 to authenticate the user name and the password. At step S3264, UCS 3067 authenticates the user name and password supplied from CCS 3068 by comparing the user name and password with those in the address book table 3202. At step S3265, UCS 3067 reports the certification result at step S3264 as a certification result response to CCS 3068. At step S3266, CCS 3068 checks use restriction set in the certification and charge setting table. In the following, a case where the use restriction is cancelled based on the check result at step S3266 is described. At step S3267, CCS 3068 supplies to NCS 3061 a ticket representing that the certification is successfully completed. Here, different tickets may be used for an application 3040 that uses the operation part, such as the operation panel 3120, of the multifunctional product 3001 and an application 3040 remotely manipulated from the computer 3210 connected via the network 3220. At step S3268, NCS 3061 reports a connection permission for the connection request at step S3260 to the external computer 3210. At step S3269, CCS 3068 supplies login user information to SCS 3069. Since the user has to be authenticated again depending on items of the initial system setting, the user login information rather than the ticket is supplied to SCS 3069. Also, CCS 3068 supplies the user login information to the copier application 3042 at step S3270. According to the sequence diagram in FIG. 72, the user can cancel use restriction through remote manipulation. It is noted that measures against DoS (Denial of Service) attack is available in accordance with the sequence diagram in FIG. 72. FIG. 73 is a sequence diagram of an exemplary use restriction cancel operation through remote manipulation wherein measures against DoS attack are devised. In the sequence diagram in FIG. 73, a user name and a password converted from a certification request are used. It is determined whether the certification request is received from the same user that issued the previous certification request, and if the certification request from the same user violates predefined restriction (for example, the number of access times or access time), the user is not authenticated. For example, after the user repeats steps S3260 through S3270 via an external computer 3210, the external computer 3210 issues a connection request to NCS 3061 at step S3271. At step S3272, NCS 3061 requests CCS 3068 to authenticate the user by delivering a user name and a password as an argument. At step S3273, CCS 3068 converts the certification request into the user name and the password. At step S3274, CCS 3068 uses the user name and the password converted at step S3273 to determine whether the certification request is from the same user that issued the previous certification request. If CCS 3068 determines that the certification request is from the same user (S3274: YES), CCS 3068 further determines whether the certification request from the user violates predefined restriction. If CCS 3068 determines that the certification request from the user violates the predefined restriction (S3275: YES), CCS 3068 informs NCS 3061 that the certification fails at step S3276. At step S3277, NCS 3061 informs the external computer 3210 that the connection request at step S3271 is denied. On the other hand, if CCS 3068 that the certification request is not from the same user (S3274: NO) or if the certification request from the same user does not violate the predefined restriction (S3275: NO), CCS 3068 performs operations corresponding to steps S3263 through S3270. According to the sequence diagram in FIG. 73, measures against DoS attack can be devised in the use restriction cancel operation through remote manipulation. FIG. 74 is a sequence diagram of another exemplary use restriction canceling operation through remote manipulation according to the second embodiment. In FIG. 74, certification is performed at an application level to control a network protocol. At step S3280, an external computer 3210 is connected to NCS 3061 in http. NCS 3061 is provided with a user name and a password from the external computer 3210. At step S3281, NCS 3061 requests WSF 3045 to acquire capability. This capability request includes the user name and the password. At step S3282, WSF 3045 requests CCS 3068 to authenticate the user by delivering the user name and the password as an argument. Here, steps S3283 through S3287 are similar to steps S3262 through S3266 in FIG. 72, and the description thereof is omitted. At step S3288, CCS 3068 supplies to WSF 3045 a ticket representing that the certification is successfully completed. Here, different tickets may be provided to an application 3040 that uses the operation part, such as the operation panel 3130, of the multifunctional product 3001 and an application 3040 remotely operated from a computer 3210 connected via the network 3220. At step S3289, WSF 3045 uses the ticket to acquire data. At step S3290, WSF 3045 supplies the data acquired at step S3289 as capability to NCS 3061. At step S3291, NCS 3061 supplies the acquired capability as n http response to the external computer 3210. At step S3292, CCS 3068 supplies login user information to SCS 3069. Since the user has to be authenticated again depending on items of the initial system setting, the user login information rather than the ticket is supplied to SCS 3069. At step S3293, CCS 3068 supplies the user login information to the copier application 3042. According to the sequence diagram in FIG. 74, the user can cancel use restriction through remote manipulation. Next, an exemplary logout operation is described. FIG. 75 is a sequence diagram of an exemplary logout operation of a multifunctional product according to the second embodiment. For example, when a user inputs a logout key, OCS 3063 reports the input key information to SCS 3069. At step S3301, SCS 3069 determines that a logout request has been provided based on the key information reported from OCS 3063, and reports the logout request to the copy application 3042. At step S3302, the copy application 3042 requests CCS 3068 to discard a ticket. At step S3303, CCS 3068 searches an issued ticket table and discards the corresponding ticket. At step S3304, CCS 3068 informs the copier application 3042 that the ticket has been discarded. At step S3306, the copier application 3042 issues to CCS 3068 a use restriction screen display request to display a certification screen on the operation panel 3120. At step S3307, CCS 3068 creates the certification screen. At step S3308, CCS 3068 issues a certification screen displaying request to display the certification screen to SCS 3069. At step S3309, SCS 3069 displays the certification screen on the operation panel 3120 by requesting OCS 3063 to display the certification screen. According to the sequence diagram in FIG. 75, when a user logs out, the multifunctional product 3001 can discard a ticket. The present invention is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing from the scope of the present invention.
