## Background
The present application is a continuation of U.S. application Ser. No. 10/359,562, filed Feb. 7, 2003, now U.S. Pat. No. 7,302,580, the entire contents of which is incorporated herein by reference.


BACKGROUND OF THE INVENTION
A technique of operating a conventional copying machine or the like is disclosed in, e.g., Japanese Patent Laid-Open No. 11-175225.
A copying machine disclosed in this reference reads an IC card or magnetic card which holds ID information representing a user. The digital combined apparatus can identify the user and allows the user to use it. This copying machine performs charging management for each user on the basis of the read ID information.
A user registers address information such as an E-mail address or FAX number in the copying machine, and another user can use the address information.
The conventional copying machine suffers the following problems.
(1) When address information is saved not in the copying machine but in the IC card or magnetic card of the user, another user cannot use the address information and has to input the same address information to the copying machine.
(2) When address information is saved in the copying machine, the address information may be used by another user who should not use it, violating the privacy.
(3) If an IC card or magnetic card is stolen, an “unauthorized” user may use the copying machine to charge the authentic user.
(4) When the user wants to transfer a file in a user's client personal computer (to be referred to as a client PC hereinafter) to the copying machine and print out the file outside his/her home, he/she cannot easily refer to an address book registered in the copying machine on the client PC. Even if the user can use the address book, the address book may be known by a third person, resulting in poor security.

In some cases, two or more digital combined apparatuses 10, 13, . . . may be connected via the network 14 to construct a system.
Data necessary to operate the digital combined apparatuses 10, 13, . . . may be managed by the digital combined apparatuses 10, 13, . . . or integrally managed by a server 15 which is connected to the network 14 and has a memory 15a. 
The operation contents of the digital combined apparatus 10 controlled by the controller 20 will be explained with reference to FIG. 3 showing the transition of the image display and FIG. 4 showing operation contents as a flow chart.
In an initial state, the window display on the operation panel 6 of the digital combined apparatus 10 provides menu buttons for selecting any one of, e.g., “copy”, “FAX”, “mail”, and “scan”, as shown as a common menu window 7 in FIG. 3.
In this state, in step S10, the reader/writer 2 detects the recording medium 3 of each user.
In step S12, the reader/writer 2 reads ID information which is written on the recording medium 3 and identifies the user.
In step S14, read of ID information triggers transition of the window display on the operation panel 6 from the common menu window 7 to a user authentication window 8 which prompts the user to input a password, as shown in FIG. 2. The user authentication window 8 corresponds to a password input popup window, and the user inputs a password set in advance.
In step S16, the controller 20 collates the input password with an authentic password saved in the memory 21 within the digital combined apparatus main body 1.
If YES in step S16, the controller 20 allows the use of the digital combined apparatus 10 in step S18, and displays a user personal menu window 9 customized for each user on the operation panel 6. The user personal menu window 9 is customized on the basis of the past operation log of each user. The user personal menu window 9 provides menu buttons for selecting general processes such as “copy”, “FAX”, “mail”, and “scan”, and menu buttons for selecting user processes such as “edit a personal address book”, “refer to a common address book”, “refer to a personal PC address book”, “load a print job”, “edit and save a user personal menu window”, and “refer to previous work settings”.
Information for displaying the user authentication window 8 and user personal menu window 9 is loaded from the memory 21 in the digital combined apparatus main body 1 in the use of the single digital combined apparatus 10. When the digital combined apparatus 10 is used as a network-connected system, the information may be loaded from the memory 21 within the main body 1 of the digital combined apparatus 10 or from the memory 15a in the server 15 connected to the network 14.
If the user selects “edit a personal address book”, he/she can input, save, or delete the personal address book in the window.
If the user selects “refer to a common address book”, he/she can select whether or not to disclose the personal address book to the common address book. If the personal address book is disclosed to the common address book, the user inputs address information to be disclosed and available information. If the personal address book is not disclosed, the user inputs undisclosed address information and unavailable information. The controller 20 performs processing of adding or not adding the address to the common address book in accordance with the available or unavailable information.
If the user selects “refer to a personal PC address book”, he/she can refer to an address book in the client PC of the user.
If the user selects “load a print job”, he/she can load data on a print job set in advance.
If the user selects “edit and save a user personal menu window”, he/she can edit or save his/her menu window.
If the user selects “refer to previous work settings”, he/she can read out and refer to previous work settings.
The user is billed for various jobs executed by the user after the password is authenticated.
If the recording medium 3 is removed from the reader/writer 2, the window displays returns from the user personal menu window 9 to the common menu window 7.
If NO in step S16, the controller 20 inhibits the use of the digital combined apparatus 10 in step S20.
Data on the above-mentioned personal address book, common address book, personal PC address book, print job, user personal menu window editing results, and previous work settings are saved in the memory 21 within the digital combined apparatus main body 1, or saved and integrally managed in the memory 15a of the server 15 connected via the network 14 to the digital combined apparatuses 10, 13.
When these data are integrally managed by the server 15, addresses saved in the common address book can be commonly used in a plurality of digital combined apparatuses 10, 13, . . . . connected via the network 14.
FIG. 5 shows information contents exchanged between the digital combined apparatus main body 1 and the recording medium 3.
The recording medium 3 of each user must hold at least ID information of the user as necessary information INF1.
When the recording medium 3 is a writable/readable IC card or memory card, information on the past job log of each user is saved as information INF2 necessary to display the user personal menu window. When the recording medium 3 is not any writable/readable medium, the information INF2 is saved in the memory 21 within the digital combined apparatus 10 or the memory 15a within the server 15.
Information INF3 on various job settings may be saved as an option in the recording medium 3.
User ID information and another information are transferred from the recording medium 3 to the digital combined apparatus main body 1. The controller 20 in the digital combined apparatus main body 1 recognizes the user ID information on the basis of the transferred information, and sets the user personal menu window on the operation panel 6, and loads and updates the job setting log. Of these pieces of information, necessary information such as data on the user personal menu window and the job setting log is transferred from the controller 20 to the memory 21 where the information is stored. Note that these pieces of information are not necessarily stored in the memory 21 within the digital combined apparatus 10. These pieces of information may be saved in the recording medium 3 of each user and loaded from the recording medium 3.
Information on the work setting log is supplied from the controller 20 to the recording medium 3 where the information is written.
When the recording medium 3 is an IC card or memory card, data can be written on the recording medium 3 by using the digital combined apparatus 10 or a user's client PC, PDA (Personal Digital Assistant), or the like. When the recording medium 3 is a magnetic card, a magnetic card reader/writer must be used. For a barcode-printed card, a barcode printing device must be used.
In the user personal menu window 9, an address book which is registered to a personal address book by a user and disclosed to the common address book can be used by another user.
The user personal menu window 9 can provide personal PC address books stored in the user's client PCs 11, 12, . . . which are connected via the network 14. The personal PC address books can be referred to, loaded into the digital combined apparatuses 10, 13, . . . , and printed out.
To realize this service, a common address book must be created and managed in a folder shared between the user's client PCs 11, 12, . . . which are connected via the network 14.
If the user selects “edit a personal address book” described above, he/she can edit the window. The editing results are saved in the memory 21 within each digital combined apparatus main body 1, or saved and integrally managed in the memory 15a of the server 15 connected to the digital combined apparatus 10 via the network 14.
When the editing results are integrally managed by the server 15, the user personal menu window 9 can also be used by other digital combined apparatuses 13, . . . connected via the network 14.
If the user selects “refer to previous work settings” described above, he/she can refer to previous work settings in the user personal menu window 9. Information on work settings is saved in the memory 21 within each digital combined apparatus main body 1, or saved and integrally managed in the memory 15a of the server 15 connected via the network 14.
When the work settings are integrally managed by the server 15, work settings performed in a plurality of digital combined apparatuses 10, 13, . . . which are connected via the network 14 are also managed. The use of previous work settings can increase the efficiency of performing the same work settings or similar work settings.
The user may be inhibited from using, e.g., various functions and addresses of the digital combined apparatus 10. In this case, information on available functions and unavailable functions is saved in the memory 21 within the digital combined apparatus main body 1, or saved and integrally managed in the memory 15a of the server 15 connected via the network.
According to the above-described embodiment, user ID information written on a recording medium is read by the reader/writer of the digital combined apparatus. This triggers automatic display of a user authentication window as a popup window which prompts the user to input a password. Only after the user inputs an authentic password, he/she can use the digital combined apparatus. As a result, the personal information, address book, and charging information of each user can be protected.
A file stored in a user's client PC which is connected to the digital combined apparatus via a network can be processed in the digital combined apparatus via the network, or used for processing such as printout or FAX transmission.
A personal PC address book managed in a client PC can be referred to on the screen of the digital combined apparatus 10, eliminating the need for any address input.
The above-described embodiment is merely an example, and does not limit the present invention. The present invention can be variously modified within the technical scope of the present invention.
