## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a computer apparatus, such as a MFP (multi-function peripheral), in which a built-in computer is incorporated.
2. Description of the Related Art
In a computer apparatus, such as a MFP, replacement of an existing model with a new model has often been performed. However, various kinds of equipment information are stored within the computer apparatus, and this equipment information contains setting information of equipment (including hardware and software resources) of the computer apparatus, and license information for using the equipment, such as application programs. In the case of a MFP, the setting information may include a recording sheet setup, a tray setup, a power-saving setup, a network setup, a FAX/MAIL address table, etc. It is necessary to transfer such information from the existing equipment to new equipment when the replacement is performed.
Conventionally, a MFP having a built-in function of printing setting information is known. If such a MFP is used for performing the replacement, the setting information is printed on a sheet by the existing model, and re-setting of the new model is performed manually while viewing the setting information of the printed sheet. As for a FAX/MAIL address and license information which are not printed out by the built-in function, such equipment information must be received by a different method and inputted to the new MFP manually. If a MFP having no function of printing setting information is used, it is necessary to acquire all the equipment information by a different method and perform re-setting of the new model manually.
On the other hand, an image processing device, such as a facsimile, which is not relevant to the replacement of computer apparatus but adapted to easily carry out a complicated setup based on marks recorded in a recording sheet in a predetermined format is disclosed in some publications: Japanese Laid-Open Patent Application No. 1-181370, Japanese Patent No. 3059643, Japanese Laid-Open Patent Application No. 2004-179780.
As mentioned above, it has been necessary to transfer equipment information, including setting information and license information, from the existing machine to the new machine by manual setting. The transferring operation is complicated and a setting error takes place in many cases, thereby causing a malfunction of the computer apparatus.
The technology disclosed in the above publications does not assume replacement of computer apparatus, and does not teach outputting the equipment information from the existing machine.
If replacement of a plurality of existing models with a plurality of new models is dealt with, from which existing model and to which new model the setting information should be transferred must be taken into consideration. However, an efficient technique is not found out.
Similarly, there is a need to divide a plurality of application programs installed in one computer apparatus, into some program groups, and install the program groups in a plurality of computer apparatuses respectively. In this case, also the license information of the programs must be divided and transferred to the plurality of computer apparatuses. However, an efficient technique for division of the license information in that case is not found out.
Not only for the replacement from existing model to new model, there is also a need to transfer a part of license information for using the equipment, such as application programs, from the source device to the destination device. However, an efficient technique for transferring the license information in that case is not found out. Similarly, an efficient technique for management of the license information at the installation or uninstallation of application programs to a computer apparatus is not found out.

A ground tint portion of the license information, cut out from a similar recording sheet printed by another MFP of the existing equipment, is pasted to the area 213.
A hand-writing is added to the license information in the area 214, which indicates the impossibility of use of the license information concerned. And the portion of the license information in the area 215 is cut off as shown. Alternatively, the portion of the setting information in the area 211 may be printed on a similar recording sheet by another MFP, so that it is copied and pasted to this portion.
FIG. 7 is a sequence diagram for explaining an example of equipment-information setting processing. The processing of FIG. 7 is started after a printed recording sheet on which the equipment information is printed (and entry or processing is performed, if needed) is set to a MFP 100 on the side of the new equipment.
Upon start of the processing of FIG. 7, the equipment information setting application 104 of the MFP 100 on the side of the new equipment requests inputting of image data of the printed recording sheet to the scanner unit 110 (step S11), and requests analysis of the inputted image data to the image-analysis unit 111 (step S12).
FIG. 8 is a flowchart for explaining an example of processing performed by the image-analysis unit 111. As shown in FIG. 8, when the image-analysis unit 111 receives an image-analysis request, the image-analysis unit 111 extracts a setting information output area according to the layout setting which indicates the position of each item on the recording sheet (step S21), and extracts two or more bar code areas from the extracted setting information output area (step S22).
And the image-analysis unit 111 extracts information from the extracted setting information output area through the OMR or OCR processing (step S23). Subsequently, the image-analysis unit 111 extracts a license information output area according to the layout setting. The above processing is repeated for the number of license information items concerned until no further license information output area is extracted (step S24).
Referring back to FIG. 7, the equipment-information setting application 104 requests decoding of the codes of setting information to the decoder unit 112 (step S13). And the equipment-information setting application 104 requests storing of the decoded setting information to the setting information holding unit 101 (step S14).
Subsequently, the equipment-information setting application 104 requests decoding of the codes of license information to the decoder unit 112 (step S15). And the equipment-information setting application 104 requests storing of the decoded license information to the license information holding unit 102 (step S16).
The decoding request and the storing request of the license information are repeated for the number of license information items concerned.
FIG. 9 shows an example of shifting and integration of equipment information. In the example of FIG. 9, the equipment information is taken over from three computer apparatuses MFP-1, MFP-2, and MFP-3 of the existing equipment to two computer apparatuses MFP-A and MFP-B of the new equipment.
First, the computer apparatus MFP-1 of the existing equipment is in the state containing setting information-1, license information-1, and license information-2, the computer apparatus MFP-2 of the existing equipment is in the state containing setting information-2, license information-3, and license information-4, and the computer apparatus MFP-3 of the existing equipment is in the state containing setting information-3 and license information-5 (step S31).
In this state, the equipment information printing processing is performed by each of the computer apparatuses MFP-1, MFP-2, and MFP-3 of the existing equipment, so that each equipment information is printed on the recording sheet (step S32).
Subsequently, processing of the recording sheet, such as patching, is performed so that a recording sheet containing the setting information-1, the license information-1 and the license information-4, and a recording sheet having containing the setting information-2, the license information-3, the license information-2 and the license information-5 are produced (step S33).
And these recording sheets are set to the scanner units 110 of the computer apparatuses MFP-A and MFP-B of the new equipment, respectively, and the equipment-information setting processing is performed so that each equipment information item is stored into the computer apparatuses MFP-A and MFP-B of the new equipment (step S34).
FIG. 10A and FIG. 10B are diagrams showing examples of license management. In FIG. 10A and FIG. 10B, the mechanism for avoiding duplication of the license information due to repeated use of a recording sheet on which the equipment information is printed with a plurality of computer apparatuses of the new equipment is shown.
In the example of FIG. 10A, a license server is arranged on a WAN (wide area network) or LAN (local area network). The license information is sent from each of the MFP-1 and the MFP-2 to the license server, and activation of corresponding application programs is carried out. The activation of the corresponding application programs is carried out by setting the corresponding application programs in a usable state after an authorized license of each program is authenticated.
When an activation request containing a number of license information items exceeding the proper number of licenses is transmitted to the license server, the license server refuses acceptance of the activation request from the MFP concerned.
In the example of FIG. 10B, the license information is transmitted between two MFPs: the MFP-1 and the MFP-2, and it is determined whether the received license information is the same as that contained in the MFP concerned.
When the result of determination indicates that it is the same license information, an alert is sent back, or use of the license information by one of the two MFPs is made invalid.
The term of validity may be included in the code information at the time of printing of the equipment information. In such a case, when the current time is not within the term of validity, execution of the equipment-information setting processing is not permitted. Thereby, it is possible to prevent the acceptance of an activation request containing a number of license information items exceeding the proper number of licenses.
A second operation pattern of the computer apparatus of the invention will be explained. The second operation pattern is applied to a case in which a part of license information is taken over from source equipment to destination equipment.
