     2. Description of the Related Art 
     MFPs (Multi Function Peripherals) connected to a network need to have enhanced security with a user authentication system, since MFPs are shared in an office and process much confidential information. MFPs have platform software as core software of the MFP, and execute a plurality of application software on the platform software. Recently MFP manufacturers provide a plurality of user authentication systems for the platform software of MFPs. The user authentication systems include Default Authentication functions, SDL (Simple Device Login) functions and SSO (Single Sign-On) function. The Default Authentication function requires an input of at least department ID and password for a user of the MFP to log into the MFP. The different department ID is allocated to each department in the office and its relationship is registered in the MFP. Therefore only persons who know the department ID and password can use the MFP. By using the Default Authentication function, the MFP administrator can manage the account of the user&#39;s usage in each department via the department ID. 
     The SDL function requires an input of at least a user name and password for a user of an MFP to log into (on) the MFP. An administrator of the MFP needs to register the user name and password into a hard disk of the MFP. Therefore only persons who know one&#39;s user name and password can use the MFP. Also, the SSO function requires an input of at least a user name and password for a user of an MFP to log into the MFP. The SSO function cooperates with a domain controller of a directory server on a network. The user name and password is used to log into network devices like personal computers (PCs) on the network. In order to use the SSO function, it is necessary to install a security application module into the PC. Therefore only persons who know one&#39;s username and password to be used in the PC can use the MFP. As described above, the current security systems of MFPs have a plurality of security functions with a different security level to log into the MFPs. The SSO function has the highest security level, the SDL function has intermediate security level and the Department ID (Default Authentication function) has the lowest security level. 
     Many varieties of USB (Universal Serial Bus) device go on sale in the world, USB memory, USB Keyboard and USB mouse etc. A user can connect the USB device to a USB connector of an information-processing device like a personal computer (PC) in an office and home. 
     When the user logs into an MFP using the user authentication systems, he or she enters at least his or her username and password using GUI (Graphical User Interface) displayed on a display of the MFP and a key unit located on the MFP. If the MFP displays a software keyboard (touch screen) on the display, the user enters his or her username and password by touching key on the displayed software keyboard. The username and password are controlled by a domain management system and maintained by the MFP administrator. However, it is not convenient for the user to enter the information in this way due to the limited size of the key unit or the software keyboard. Under this situation, the user hopes to connect his or her favorite USB keyboard (hardware keyboard) to the MFP in order to enter his or her username and password. Furthermore generally MFP administrators hope to connect a USB keyboard to an MFP in order to manage the MFP by inputting information, since MFPs have been computerized like PCs.

       FIG. 2  is a block diagram illustrating a schematic configuration of a logon management system including one of the information processing devices according to an embodiment of the present invention. In this regard, although a logon management system is shown as an embodiment, the present invention is not limited to this. The present invention is applied to a network system in which processing is performed by connecting through a network such as a LAN (local area network), WAN (wide area network), etc., as long as it is an environment in which the logon management software can be executed. 
     In  FIG. 2 , reference numeral  1  denotes one of personal computers (Client PC  1  and NS  3 ) shown in  FIG. 1 , and includes a CPU (central processing unit)  14  which executes processing on documents including a combination of graphics, images, characters, tables (including spreadsheets), etc., based on a document processing program, etc., stored in a program ROM of a ROM (read only memory)  16  or an external memory  24  (HD, USB chip and so on). The CPU  14  integrally controls each of the devices connected to a system bus  17 . Also, the program ROM of the ROM  16  or the external device  24  (USB chip) stores an operating system (OS), which is the control program of the CPU  14  and the domain management software, etc., a font ROM of the ROM  16  or the external device  24  (USB chip) stores font data, etc., to be used for the document processing described above, and a data ROM of the ROM  16  or the external device  24  (USB ship) stores various data to be used for the above-described document processing and the domain management software, etc. Reference numeral  15  denotes a RAM (random access memory), and functions as a main memory, a work area, etc., of the CPU  14 . 
     Reference numeral  18  is a keyboard controller (KBC), and controls the input from a normal keyboard  22  and an unillustrated pointing device. Reference numeral  19  is a CRT controller (CRTC), and controls the display of a CRT (cathode ray tube) display  23 . CRTC  19  can control the display of LCDs (Liquid crystal displays). Reference numeral  20  is a USB controller (USBC), and controls the external device  24  such as a USB keyboard and USB memory chip, etc., which stores a boot program, various applications including the domain management software, font data, user files, etc. 
     Reference numeral  21  is a print controller (PRTC), which is connected to a print control device (MFP)  4  through a predetermined bi-directional interface (interface)  25  via the network  2 , and executes communication control processing with print control device  4 . In this regard, CPU  26  executes, for example, outline-font expansion (rasterization) processing into a display information RAM, which is set in RAM  27 , and provides WYSIWYG (what you see is what you get) on CRT  23 . Also, CPU  26  opens various registered windows like logon GUIs and a software keyboard, and executes various data processing based on the commands instructed by a touch screen on operation panel  35  or external device  38  (USB keyboard). 
     In print control device  4 , reference numeral  26  is a CPU. CPU  26  outputs an image signal as output information to a print part (printer engine)  32  connected to a system bus  29  based on the control program, etc., stored in a program ROM of a ROM  28  or the control program, etc., stored in HD  36 . Also, the program ROM of the ROM  28  stores a control program, etc., of the CPU  26 . A font ROM of the ROM  28  stores font data, etc., to be used when the above-described output information is created. A data ROM of the ROM  28  stores information, etc., to be used in Client PC  1  when the print control device  4  does not have a hard disk (HD)  36 , etc. 
     CPU  26  is capable of performing communication processing with Client PC  1  and/or NS  3  through an I/F unit  30 . Reference numeral  27  is a RAM which functions as a main memory, a work area, etc., of CPU  26 , and the memory capacity thereof can be expanded by an optional RAM connected to an unillustrated expansion port. In this regard, the RAM  27  is used for an output information expansion area, environment data storage area, an NVRAM (Non-Volatile RAM), etc. 
     HD  36  stores font data, an emulation program, form data, logon management software shown in  FIG. 3 to 5 , information related to logon GUIs and software keyboard shown in  FIG. 6  to  FIG. 12 , etc. Reference numeral  33  is a scanner part I/F and controls documents scanned by scanner part  34  (scanner engine). The scanned document may be printed by print engine  32  and sent to Client PC  1  by using a telephone line in a facsimile mode of print control device  4 . The scanned document is stored into external device  38  (USB memory chip). If a user selects documents stored in USB memory chip  38 , the documents are printed by print engine  32 . Also, reference numeral  35  is an operation panel (touch screen display unit) to display the logon GUIs and a software keyboard shown in  FIG. 6  to  FIG. 12  and receive user instructions. The operation panel also includes a key unit (small hardware unit) to enter information and instructions of the user. Reference numeral  37  is a USB controller (USBC), and controls the external device  38  such as a USB keyboard (hardware keyboard) and a USB memory chip, etc., which stores a boot program, various applications, logon management software shown in  FIG. 3 to 5 , font data, user files, etc. 
       FIG. 3  is a flowchart illustrating a checking process of the logon management system to be executed in MFP  4  (print control device). If a user powers up or boots up MFP  4 , the checking process of the logon management software is executed. The checking process is executed periodically until the user powers down MFP  4  or log into MFP  4 . When executing the checking process, CPU  26  determines if the USB keyboard  38  is connected to USBC  37  of MFP  4  in step  101 . If No in step  101 , CPU  26  executes a software keyboard process of the logon software shown in  FIG. 5  in step  102 . And if Yes in step  101 , CPU  26  executes a hardware keyboard process of the logon software shown in  FIG. 4  in step  103 . And then those steps are repeated periodically until the user powers down MFP  4  or log into MFP  4 . The user can connect USB keyboard  38  to MFP  4  at any time. 
       FIG. 6  is a diagram showing a logon GUI for a software keyboard to be displayed on an operation panel of the MFP. In  FIG. 6 , the logon GUI for software keyboard has the series of four icons  40  to  43  at the bottom-left-hand corner. The purpose of the first icon  40  is to indicate the status of the USB keyboard connection. The remaining three icons  41  to  43 , which are disabled in the logon GUI, are relevant only when the USB keyboard  38  is in use. Their purpose is to indicate the status of “Caps Lock” ( 41 ), “Number Lock” ( 42 ) and the “overwrite” ( 43 ) mode respectively. If USB keyboard  38  is connected to MFP  4  in step  101  and the USB keyboard  38  becomes ready for use, the relevant icon changes to that shown in  FIG. 7 , and the same instruction (a link) which appeared underneath the two text fields (which correspond to “User Name” and “Password”) disappears. This instruction implies that the user could bring up the software keyboard by touching the associated text field (a link). It would be wrong to display this instruction since the software keyboard would be disabled when USB keyboard  38  becomes ready for use. It should be noted that touching any of the text field will still give that field the input focus, but it would not cause the software keyboard to appear.  FIG. 7  is a diagram showing a logon GUI for a hardware keyboard to be displayed on an operation panel of the MFP.  FIG. 7  also shows the icons  41  to  43  for enabled “Caps Lock”, “Number Lock” and the “overwrite” mode instructed by USB keyboard  38 . If the USB keyboard is disconnected at any point, statuses of all the four icons change back to those shown in  FIG. 6  and the instruction underneath the two text fields reappear. 
       FIG. 4  is a flowchart illustrating a USB keyboard process of logon management system to be executed in MFP  4 . In case that a connection of USB keyboard  38  is detected in step  101 , CPU  26  displays a logon GUI for a hardware keyboard shown in  FIG. 7  on operation panel  35  in step  201 . CPU  26  determines if instructions are received from USB keyboard  38  regarding “Caps Lock” ( 41 ), “Number Lock” ( 42 ) and the “overwrite” ( 43 ) mode. If yes in step  202 , CPU  26  changes corresponding icons to the icons indicating disabled mode or the icons indicating enabled mode based on the instructions in step  203 . If No in step  202 , CPU  26  receives at least user name and password that the user enters into a log on GUI for a hardware keyboard shown in  FIG. 8 . When the user selects “login button” at the bottom-right-hand corner on the logon GUI, CPU  26  checks the user name and password with network server  3  and determines if the login is succeeded in step  205 . The network server  3  is always managing the user name and password. If No in step  205 , CPU  26  repeats the steps from step  204 . If yes in step  205 , this process ends. 
       FIG. 5  is a flowchart illustrating a software keyboard process of logon management system to be executed in MFP  4 . In case that a connection of USB keyboard  38  is not detected in step  101 , CPU  26  displays a logon GUI for a software keyboard shown in  FIG. 6  on operation panel  35  in step  301 . CPU  26  determines if any of one of the text fields (for the user name and the password) in the logon GUI was touched by the user in step  302 . If yes in step  302 , CPU  26  displays a software keyboard shown in  FIG. 9  on the operation panel  35  and receives information like at least a user name and password that the user enters into the field of the logon GUI. After the user selects “OK button” at the bottom-right-hand corner on the software keyboard, CPU  26  displays the logon GUI for software keyboard shown in  FIG. 6  again. And then CPU  26  determines if any of remaining text field was touched by the user in step  304 . If yes in step  304 , CPU  26  displays a software keyboard shown in  FIG. 9  on the operation panel  35  and receives information like at least a user name and password that the user enters into the field of the logon GUI. After the user selects “OK button” at the bottom-right-hand corner on the software keyboard, CPU  26  displays the logon GUI for software keyboard shown in  FIG. 6  again. And then when the user selects “login button” at the bottom-right-hand corner on the logon GUI, CPU  26  checks the user name and password with network server  3  and determines if the login is succeeded in step  306 . The network server  3  is always managing the user name and password. If No in step  306 , CPU  26  repeats the steps from step  302 . If yes in step  306 , this process ends. 
     In the above-described embodiment, after the user enters some part of the information into the text field using the logon GUI for a hardware keyboard shown in  FIG. 8 , the user can disconnect the USB keyboard  38  from MFP  4  in order to connect USB memory chip to MFP  4 . At this time, CPU  26  detected that USB keyboard  38  was disconnected from MFP  4  and displays a logon GUI for a software keyboard shown in  FIG. 10  keeping the part of the information (111) that the user has already entered in to the logon GUI for a hardware keyboard. If CPU  26  determines that the user touched the text field (for user name) including the part of the information, CPU  26  displays a software keyboard shown in  FIG. 11  on the operation panel  35  so that user continue to enter remaining part of the information. After the user selects “OK button” at the bottom-right-hand corner on the software keyboard, CPU  26  displays a logon GUI for software keyboard shown in  FIG. 12  so that the user enter another information into remaining text field in the same manner. And then when the user selects “login button” at the bottom-right-hand corner on the logon GUI, CPU  26  checks the information with network server  3  and determines if the login is succeeded. The information (ex. 111222) is generated by combining the part of the information (ex. 111) entered into the logon GUI for a hardware keyboard and the remaining part of the information (ex. 222) entered into the logon GUI for a software keyboard. The network server  3  is always managing the information like a user name and password. Also, after the user enters some part of the information into the text field using the logon GUI for a software keyboard, the user can connect the USB keyboard  38  to MFP  4 . In a same manner, the user can continue to enter the remaining part of the information and log on MFP  4  using the combined information. MFP  4  can change the logon GUI from the logon GUI for software keyboard to the logon GUI for hardware keyboard or from the logon GUI for hardware keyboard to the logon GUI for software keyboard based on a connection of USB keyboard  38  at any time. Therefore the user can continue to enter the information even though the GUI was changed. Also the information to logon MFP  4  can be one of the user name and password. 
     Also, in the above-described embodiment, various functions are achieved by reading the programs for achieving the functions in Client PC  1 , NS  3  or MFP  4  into the memory (RAM) and the CPU executing these functions. However, the invention is not limited to this, and all of the processing or part of the functions may be achieved by dedicated hardware. Also, the above-described memory may be constituted by a non-volatile memory such as a magnetic optical disk unit, a flash memory, etc., a read-only recording medium such as a CD-ROM, etc., a volatile memory other than a RAM, or a computer-readable and writable recording medium by the combination of these. 
     Also, a program for achieving various processing functions in Client PC  1 , NS  3 , MFP  4  may be recorded into a computer-readable recording medium, and the program code recorded in the recording medium may be read into a computer system, and each processing may be performed by executing the program code. In this regard, a “computer system” mentioned here includes an OS, hardware such as a peripheral device, etc. 
     Also, a “computer-readable recording medium” means a portable medium such as a flexible disk, a magnetic optical disk, a ROM, a CD-ROM, etc., and a storage device such as a hard disk contained in a computer system. Furthermore, a “computer-readable recording medium” includes a device for holding a program for a certain period of time such as an internal volatile memory (RAM) of a computer system to be a server or a client when the program is transmitted through a network such as the Internet, etc., and a communication line such as a telephone line, etc. 
     Also, the above-described program may be transmitted from a computer system storing the program in a storage device, etc., through a transmission medium, or may be transmitted to another computer system by a transmitted wave in the transmission medium. Here, a “transmission medium” for transmitting the program means a medium having an information transmission function such as a network (communication network), for example, the Internet, etc., and the communication line such as a telephone line, etc. Also, the above-described program may achieve part of the above-described functions. Furthermore, the program may achieve the above-described functions by combining with the program that is already recorded in a computer system, that is to say, the program may be a differential file (differential program). 
     Also, a program product such as a computer-readable recording medium which records the above-described program may be applied to an embodiment of the present invention. The above-described program, recording medium, a transmission medium, and the program product are included in the scope of the present invention. As described above, a detailed description has been given of the embodiments of the present invention with reference to the drawings. However, a specific structure is not limited to the embodiments, and a design, etc., are included within the spirit and scope of the present invention.
