BACKGROUND  
         [0001]    1. Field  
           [0002]    The present application relates to a method and system for information control, and more particularly to a method and system for information control that can effectively perform an automatic payment for machine maintenance expenses.  
           [0003]    2. Background  
           [0004]    Many image forming devices, such as a laser printer, a copying machine, a facsimile machine, etc. are provided with a storage means for storing various kinds of job information mainly for maintenance purposes. The job information typically includes daily power-on hours, a cumulative number of prints performed, dates of installation relative to specific components requiring a periodic exchange such as toner, a photoconductive member, etc. Based on the job information, an image forming apparatus usually calculates a remaining life length of each specific component and determines if any one of the specific components needs to be exchanged due to an end of its life. If the machine determines that a specific component needs to be exchanged, this will be indicated to the user who will then take a necessary action; exchanging the component by the user alone or contacting a repair center to ask for service.  
           [0005]    Office equipment technology increasingly takes into account concerns for natural resource savings and recycling. Published Japanese Unexamined Patent Application, No. 09-120249, relating to a recycling of a process cartridge used in an image forming apparatus is one example. This Application, No. 09-120249, describes an image forming apparatus which includes a process cartridge having a storage for storing recycling information relative to the process cartridge. The process cartridge of this image forming apparatus further includes a connection connecting to the above storage, a detection for detecting the recycling information, and a power supply unit. The image forming apparatus attempts to appropriately indicate to the user when to carry out a recycling of the process cartridge.  
           [0006]    Recycling of the process cartridge involves procurement of a new process cartridge, shipping arrangement, user&#39;s settlement of the fee for exchange, storage of the exchanged process cartridge until it is collected by a collection company, etc, in addition to actually replacing the cartridge. As these processes are ongoing, the user may place an order for consumable items such as toner, which will also involve processes similar to the above. As a result, this may require a complex system for a control center to handle a plurality of customers of image forming apparatuses.

The driving unit  2   f  controls a transfer of a recording sheet. The process unit  2   g  controls a process in which the latent image formed with the optical unit  2   e  is developed with toner and is transferred onto the recording sheet. The fixing unit  2   f  controls a fixing process for fixing the toner image on the recording sheet.  
         [0042]    The process cartridge  3  includes an electronic money unit  5  which has a configuration similar to that of the electronic money IC card, as shown in FIG. 1, and which includes an electronic money IC (integrated circuit) chip  5   a , a data input/output port  5   b , a CPU (central processing unit)  5   c , and a memory  5   d . The process cartridge  3  is configured to be detachable from the image forming apparatus  1 . The electronic money IC chip  5   a  handles electronic money information.  
         [0043]    The communications unit  6  is connected to a communications network, such as a public switched telephone network (PSTN), a local area network (LAN), a wide area network (WAN), the Internet, etc., and performs data communications with a data terminal such as a PC (personal computer) through the communications network under the control of the CPU  2   c  of the control unit  2 . The operation panel unit  7  includes various person-machine interface components (not shown), such as an alphanumeric-key pad, an LCD (liquid crystal display), functions keys, etc., for exchanging commands and responses between the operator and the CPU  2   c.    
         [0044]    As illustrated in FIG. 2, the image forming apparatus  1  includes an original reading section  9  at an upper part thereof and an electrophotographic image forming section  10  at a mid part thereof. In the original reading section  9 , an original D is placed on an original input table  9   a  and is input by a pickup roller  9   b  into an original separation unit  9   c  which is configured to separate the original D one by one with a feed roller and a reverse roller. The separated original D is transferred with a plurality of transfer rollers  9   d  to an original reading sensor  11  which reads the original D. After passing by the original reading sensor  11 , the original D is further transferred and is ejected by an ejection roller  9   e  to an original ejection tray  9   f.    
         [0045]    The image forming section  10  uses an electrophotographic method and includes a photoconductive member  12  and, around the photoconductive member  12 , several components such as a charging unit  10   a , a development unit  10   b , a transfer roller  17 , a cleaning unit  10   c  included in the process cartridge  3 . The photoconductive member  12  is arranged to be exposed to laser light L generated by a laser optical system unit  13  in accordance with image data.  
         [0046]    In the image forming process, a recording sheet P contained in a sheet cassette  14  is picked up by a feed roller  14   a  and is transferred by a transfer roller  15  to a registration roller  16 . The registration roller  16  transfers the recording sheet D to a nip portion formed between the photoconductive member  12  and the transfer roller  17  in synchronism with the rotation of the photoconductive member  12 , wherein a latent image formed by an exposure with the laser light L is developed into a visible image with toner on the photoconductive member  12 . The toner image formed on the photoconductive member  12  is then transferred onto the recording sheet P by the transfer roller  17 . After that, the recording sheet P is transferred to a fixing unit  18  which fixes the toner image with heat and pressure using a heat roller  18   a  and a pressure roller  18   b . The recording sheet P thus having the fixed toner image thereon is further transferred to an ejection roller  10   d  and is ejected by the ejection roller  10   d  to a recording sheet ejection tray  10   e.    
         [0047]    The entire control of the image forming apparatus  1  including a control of the above-described sequential operations performed by the original section  9  and the image forming section  10  is executed by an electric control system included in the control unit  2  containing various electric components such as a an electrical power supply (battery) and a plurality of integrated circuits.  
         [0048]    As shown in FIG. 3, the image forming apparatus  1  includes an electronic money IC (integrated circuit) card inlet  1   a  for receiving the EM IC card  4 . When the EM IC card  4  is inserted into the IC card inlet  1   a , the data input/output port  4   b  (FIG. 1) is connected to the data input/output port  1   b  and data exchange therebetween is thereby made possible.  
         [0049]    Therefore, the thus-configured image forming apparatus  1  can exchange various kinds of information with the EM IC card  4  when the EM IC card  4  is inserted into the IC card inlet  1   a  of the image forming apparatus  1 . For example, payment of a fee for exchanging a consumable item such as toner or a maintenance part requiring a periodic exchange, which may be determined in accordance with a number of prints, for example, may be executed through the above card operation.  
         [0050]    Also, with the EM unit  5  provided to the process cartridge  3  (FIG. 1), the process cartridge  3  can handle the monetary information and the payment of fee for the process cartridge  3  or other fees associated with a recycle work related to the process cartridge  3 .  
         [0051]    The data input/output port  1   b  (FIG. 1) may be combined with the data input/output port  5   b  and, in this case, the combined data input/output port  5   b  is positioned next to the EM IC card inlet  1   a  (FIG. 3).  
         [0052]    The EM IC card  4  may handle various kinds of monetary information including the information indicating an amount of money and various kinds of property information such as an identification for identifying an owner of the EM IC card  4 , etc. The EM unit  5  of the process cartridge  3  handles various kinds of property information such as a part number or a type number for identifying the process cartridge  3 , a manufacturing number, functional information such as a number of effective prints with the process cartridge  3 , physical dimensions, etc., and price information representing a price of the process cartridge  3 . When the process cartridge  3  is installed in the image forming apparatus  1 , the image forming apparatus  1  receives the above various kinds of information from the EM unit  5  of the process cartridge  3 . With the information received from the EM unit  5 , the image forming apparatus  1  can automatically proceed the payment of an expense of the process cartridge  3  and suitably adjust the conditions for the image forming process.  
         [0053]    When the process cartridge  3  is removed from the image forming apparatus  1  at a time of the periodic exchange, the monetary information is stored in the EM unit  5 . In this case, the monetary information includes money information such as a recycle fee and so on and information for authorizing an exchange of the money information, as well as history information related to the process cartridge  3  and to the user and information useful for the recycle work.  
         [0054]    The process cartridge  3  removed from the image forming apparatus  1  is subjected to an exchange of the monetary information with the EM IC card  4 . For this purpose, the process cartridge  3  has an IC (integrated circuit) card inlet  3   a , as shown in FIG. 4, through which the EM IC card  4  is inserted and the data input/output port  4   b  of the EM IC card  4  is connected to the data input/output port  5   b . When the EM IC card  4  is connected to the process cartridge  3 , the EM IC card  4  is first checked if it is a proper card with the information for authorizing an exchange of monetary information. If the EM IC card  4  is proved as a proper card, the monetary information is exchanged. The EM unit  5  of the process cartridge  5  is provided with a backup battery  3   b , as shown in FIG. 4, for storing the monetary information for a relatively long time period and performing the exchange of the various information, etc. This backup battery  3   b  may be charged during the time when it is installed in an operable condition in the image forming apparatus  1 .  
         [0055]    The process cartridge  3  removed from the image forming apparatus  1  may be collected by a recycle company, for example, and, at the recycle company, the process cartridge  3  can be subjected to an exchange of the monetary information with an apparatus having a function similar to that of the EM IC card  4 . The money information may be sent to a host computer of an accounting section of the recycle company so as to be used for invoicing, and the property information may be sent to a host computer of a work shop of that company so that a recycle work may be conducted in accordance with the history information, for example.  
         [0056]    The communication unit  6  of the image forming apparatus  1  is configured to transmit and receive the monetary information at a relatively high speed so that transaction of monetary information can be quickly processed. With this feature, the image forming apparatus  1  can send the monetary information on an as-needed basis to, for example, a control center which deals with the image forming apparatuses at an one-by-one basis. Such a control center can collect the user information according to the property information included in the monetary information, control an inventory of necessary parts and consumable items according to the contents of the property information, and control a history of individual apparatus according to the property information representing the machine history, the machine configuration, etc.  
         [0057]    The communication unit  6  performs the communications of the monetary information with the control center in response to a demand raised by the image forming apparatus  1 . For example, the communication unit  6  performs the communications when the image forming apparatus  1  receives the monetary information from the EM IC card  4  and needs to perform the transaction of the monetary information. For another example, the communication unit  6  performs the communications when the image forming apparatus  1  receives the monetary information from the process cartridge  3  after an exchange of the process cartridge  3  at a periodic exchange occasion.  
         [0058]    The image forming apparatus  1  may perform the above communications of the monetary information with the control center through the communication unit  6  during a time of a self-diagnostic test at a power-on time, during a specific time of a day when the image forming apparatus  1  is less occupied with the image forming operation, or at a time immediately before the power of the image forming apparatus  1  is shut down.  
         [0059]    The image forming apparatus  1  may use various kinds of networks including the Internet for the communications with the communication unit  6 . When the Internet is used, the image forming apparatus  1  uses E-mail or an FTP (file transfer protocol) function. Thereby, the image forming apparatus  1  performs quick communications of the monetary information utilizing various popular software products, without a need of establishing a new network system and software.  
         [0060]    Referring now to FIG. 5, a control system of the monetary information according to a preferred embodiment is explained. A monetary information control system  100  includes a control center  20  and a plurality of image forming apparatus which are provided with a configuration similar to that of the image forming apparatus  1  of FIG. 1 and communicate with the control center  20 . For convenience sake, the image forming apparatus  1  is shown in FIG. 5 as a representative of the plurality of the image forming apparatus.  
         [0061]    AS shown in FIG. 5, the monetary information control system  100  includes a host computer  21  which includes a data base  22  of history information and a communication unit  26  for performing communication with the communication unit  6  of the image forming apparatus  1  via a network  25 . The data base  22  includes a plurality of history information sectors for the image forming apparatuses. Each sector stores history information of a specific image forming apparatus. For example, a sector labeled with the address ADR# 005  stores the history information of the image forming apparatus  1 .  
         [0062]    In the monetary information control system  100 , the image forming apparatus  1  is provided with a specific address, ADR # 005 , for example, as shown in FIG. 5, by the control center  20  when the image forming apparatus  1  is installed and a line connection for communications between the image forming apparatus  1  and the host computer  21  is established with this specific address. When the line connection is established using the address ADR# 005  between the image forming apparatus  1  and the host computer  21 , the image forming apparatus  1  can read and write history information relative to the address ADR# 005  in the data base  22  of the host computer  21 .  
         [0063]    As described above, the image forming apparatus  1  is provided with information used in the process for obtaining authorization of monetary information communications. Referring to FIG. 6, an exemplary procedure of an initial setting operation performed by the image forming apparatus  1  for authorization of monetary information communications is explained.  
         [0064]    In Step S 1  of FIG. 6, the CPU  2   c  of the control unit  2  in the image forming apparatus  1  reads and recognizes a machine configuration and an address ADR# 005  provided by the control center  20  when power is supplied to the image forming apparatus  1  for the first time after its installation. In Step S 2 , the CPU  2   c  generates configuration information based on the machine configuration. The configuration information is stored in the memory  2   d . In Step S 3 , the CPU  2   c  instructs the communication unit  6  to connect to the host computer  21  using the address ADR# 005 . In Step S 4 , the CPU  2   c  sends the configuration information to the host computer  21  via the communication units  6  and  26 .  
         [0065]    In Step S 5 , the host computer  21  generates certified configuration information by adding an authorization code to the configuration information received from the image forming apparatus  1 . The authorization code is calculated by the host computer  21  based on specific rules determined by the control center  20 . The certified configuration information is stored in the data base  22  at an address assigned in association with the address ADR# 005 . FIG. 7 shows an example of the contents of the data base  22 . In Step S 6 , the host computer  21  sends the certified configuration information to the image forming apparatus  1 .  
         [0066]    In Step S 7 , upon a receipt of the certified configuration information sent from the host computer  21 , the CPU  2   c  of the control unit  2  in the image forming apparatus  1  verifies the certified configuration information with the configuration information stored in the memory  2   d . In Step S 8 , the CPU  2   c  determines if the configuration is properly verified in Step S 7 . If the configuration is not properly verified in Step S 7  and the determination result of Step S 8  is NO, the CPU  2   c  returns the process to Step S 4  to repeat the above-described procedure until the configuration is properly verified. If the configuration is properly verified in Step S 7  and the determination result of Step S 8  is YES, the CPU  2   c  proceeds the process to Step S 9  in which the CPU  2   c  stores the certified configuration information into the memory  2   d . Then, the CPU  2   c  ends the process.  
         [0067]    Referring to FIG. 8, an exemplary authorization procedure when a request for communication is raised by the image forming apparatus  1  is explained. In the monetary information control system  100 , the image forming apparatus  1  raises a request for communication to exchange the monetary information and the history information when a payment transaction has occurred in the image forming apparatus  1 , when the process cartridge  3  is exchanged, when the recycle work is performed, and so on. In Step S 10  of FIG. 8, the CPU  2   c  generates a request for communication. In Step S 11 , the CPU  2   c  instructs the communication unit  6  to connect to the host computer  21  using the address ADR# 005 . In Step S 12 , the CPU  2   c  sends the certified configuration information stored in the memory  2   d  to the host computer  21 .  
         [0068]    In Step S 13 , the host computer  21  verifies the certified configuration information sent from the image forming apparatus  1  with the information stored in the data base at the address ADR# 005 . In Step S 14 , the host computer  21  determines if the certified configuration information is properly verified. The host computer  21  sends authorization to the image forming apparatus  1  if the certified configuration information is properly verified and the determination result of Step S 14  is YES, or rejection if the certified configuration information is not properly verified and the determination result of Step S 14  is NO. In the case of rejection, the CPU  2   c  of the control unit  2  of the image forming apparatus  1  receives the rejection sent from the host computer  21  and displays a message indicating that the request for communication is rejected through the operation panel unit  7 , in Step S 17 . Then, the process ends.  
         [0069]    In Step S 15 , the CPU  2   c  receives the authorization sent from the host computer  21 . In Step S 16 , the CPU  2   c  starts the communications for exchanging the monetary information with the host computer  21 . In Step S 18 , the host computer  21  checks if the communications for the monetary information with the image forming apparatus  1  is completed. The check of Step S 18  forms a NO loop to return to Step S 16  unless the check result becomes YES.  
         [0070]    If the communications with the image forming apparatus  1  is completed and the check result of Step S 18  is YES, the host computer  21  generates new certified configuration information by adding new authorization code to the previous certified configuration information, in Step S 19 . In Step S 20 , the host computer  21  sends the new certified configuration information to the image forming apparatus  1 .  
         [0071]    In Step S 21 , the image forming apparatus  1  verifies the new certified configuration information sent from the host computer  21  with the certified configuration information stored in the memory  2   d . In Step S 22 , the CPU  2   c  determines if the new certified configuration information is properly verified in Step S 21 . If the new certified configuration information is not properly verified and the determination result of Step S 22  is NO, the CPU  2   c  sends the certified configuration information to the host computer  21 , in Step S 23 , and the process then returns to Step S 19  to repeat the above-described operations until the new certified configuration information is properly verified.  
         [0072]    If the new certified configuration information is properly verified and the determination result of Step S 22  is YES, the CPU  2   c  updates the configuration information with the new certified configuration information in the memory  2   d , in Step S 24 . Then, the process ends.  
         [0073]    In this way, the monetary information control system  100  can allow the host computer to properly identify an apparatus (i.e., the image forming apparatus  1 ) that requests communications for exchanging monetary information by executing revision and confirmation of the certified configuration information given to the apparatus each time when the host computer receives such request. Thereby, the monetary information control system  100  can achieve a relatively high level information security.  
         [0074]    Referring to FIG. 9, an exemplary procedure for authorizing communications when the image forming apparatus  1  changes its configuration is explained. In this case, an approval code for allowing a configuration change is predefined and is prestored in the history information.  
         [0075]    In Step S 25  of FIG. 9, the CPU  2   c  of the control unit  2  in the image forming apparatus  1  recognizes the configuration through the self-diagnostic at a power-on time. In Step S 26 , the CPU  2   c  generates configuration information and temporarily stores it in the memory  2   d . In Step S 27 , the CPU  2   c  checks if the generated configuration information is identical to the previous configuration information (previous certified configuration information). If the generated configuration information is identical to the previous configuration information and the check result of Step S 27  is YES, the process ends. If the generated configuration information is not identical to the previous configuration information and the check result of Step S 27  is NO, the process proceeds to Step S 28  in which the CPU  2   c  connect to the host computer  21  with the address AR# 005 . In Step S 29 , the CPU  2   c  sends the previous certified configuration information to the host computer  21 . In Step S 30 , the host computer  21  verifies the configuration information (previous certified configuration information) sent from the image forming apparatus  1  with the configuration information (previous certified configuration information) stored in the data base at ADR# 005 . In Step S 31 , the host computer  21  determines if the above verification is completed successfully. If the host computer  21  fails in the above verification and the check result of Step S 31  is NO, the host computer  21  sends rejection to the image forming apparatus  1 . In Step S 32 , the image forming apparatus  1  receives the rejection of the communications and displays a message indicating that the request for communication is failed, through the operation panel unit  7 . Then, the process ends.  
         [0076]    If the host computer  21  succeeds in executing the above verification and the check result of Step S 31  is YES, the host computer  21  sends authorization for the communications to the image forming apparatus  1 . In Step S 33 , after the image forming apparatus  1  receives the authorization sent from the host computer  21 , the predefined approval code is entered through the operation panel unit  7  by the operator and the CPU  2   c  sends it to the host computer  21 . As an alternative to sending the approval code, the operator may send identification information for identifying a specific card owner registered in the EM IC card  4 . Further, the operator may send the above identification information with a predefined password for a configuration change.  
         [0077]    In Step S 34 , the host computer  21  verifies the approval code sent from the image forming apparatus  1  and determines if the approval code is correct. If the approval code is incorrect and the determination result of Step S 34  is NO, the process goes to Step S 32  so as to send rejection of the communications to the image forming apparatus  1 , as described above. If the approval code is correct and the determination result of Step S 34  is YES, the host computer  21  sends confirmation of the approval code to the image forming apparatus  1 . Then, in Step S 35 , upon a receipt of the acceptance sent from the host computer  21 , the CPU  2   c  of the control unit  2  in the image forming apparatus  1  sends the new configuration information temporarily stored in the memory  2   d  in Step S 26  to the host computer  21 . In Step S 36 , upon a receipt of the new configuration information sent from the image forming apparatus  1 , the host computer  21  generates new certified configuration information by adding a new certification code to the new configuration information received from the image forming apparatus  1  and stores it in the data base  22  at ADR# 005 . In Step S 37 , the host computer  21  sends the new certified configuration information to the image forming apparatus  1 .  
         [0078]    In Step S 38 , upon a receipt of the new certified configuration information sent from the host computer  21 , the CPU  2   c  of the control unit  2  in the image forming apparatus  1  verifies the configuration information included in the new certified configuration information sent from the host computer  21  with the new configuration information stored in the memory  2   d . In Step S 39 , the CPU  2   c  determines if the above verification is successfully completed. If the verification is not successfully completed and the determination result of Step S 39  is NO, the process returns to Step S 35  to repeat the above-described procedure until the verification is successfully completed. If the verification is successfully completed and the determination result of Step S 39  is YES, the CPU  2   c  updates the configuration information in the memory  2   c  with the new certified configuration information sent from the host computer  21 .  
         [0079]    In this way, the monetary information control system  100  can allow an apparatus (i.e., the image forming apparatus  1 ) to change its configuration and to implement such configuration change to the data base of the host computer without losing its relatively high level of information security. Therefore, the monetary information control system  100  can reasonably safely be used even with the Internet, for example.  
         [0080]    Referring to FIG. 10, an exemplary procedure of an automatic fee payment for the image forming operations performed on the image forming apparatus  1  using the electronic money IC card  4  is explained. In this case, a fee for one operation of the image forming is predefined and the fee is paid from the EM IC card  4  to the image forming apparatus  1 .  
         [0081]    In Step S 41  of FIG. 10, the CPU  2   c  of the control unit  2  in the image forming apparatus  1  checks if the EM IC card  4  is inserted to the IC card inlet  1   a  of the image forming apparatus  1 . The check of Step S 41  forms a NO loop for holding the process until the EM IC card  4  is inserted. If the EM IC card  4  is inserted and the check result of Step S 41 , the CPU  2   c  receives the monetary information from the EM IC card  4 , in Step S 42 . The monetary information includes a present amount of money remaining in the EM IC card  4 , an owner&#39;s name for identifying a name of the owner of the EM IC card  4 , and so on.  
         [0082]    In Step S 43 , the CPU  2   c  displays the present amount of money and the owner&#39;s name received from the EM IC card  4  through the operation panel unit  7 . With this process, the operator can confirm the contents of the EM IC card  4 , such as the present amount of money, the card owner&#39;s name, etc.  
         [0083]    In Step S 44 , the CPU  2   c  instructs the EM IC card  4  using the card owner&#39;s name to send the history of usage of the image forming apparatus  1 . With this process, the various kinds of special services on the usage of the image forming apparatus  1  may be applied to the card owner. For example, the fee for the image forming operation per recording sheet may be discounted. As another example, certain conditions for the image forming operation, such as a sheet size, a sheet orientation, etc., may be preset for the user&#39;s convenience.  
         [0084]    In Step S 45 , the CPU  2   c  checks if any input is made through the operation panel unit  7  by the user of the EM IC card  4 . The check of Step S 45  forms a NO loop for holding the process until an input is made. If the user gives a command through the operation panel unit  7  and the check result of Step S 45  is YES, the CPU  2   c  further checks in Step S 46  if the user has entered a cancel code for canceling the command input. If the user has put in a cancel code and the check result of Step S 46  is YES, the CPU  2   c  displays a message indicating that the operation is canceled through the operation panel unit  7 , in Step S 47 . Then, the process ends.  
         [0085]    If the user puts in another code (i.e., a confirmation code) rather than a cancel code and the check result of Step S 46  is NO, the process proceeds to Step S 48 . In Step S 48 , the CPU  2   c  displays the input command through the operation panel unit  7 . Further, in Step S 48 , the CPU  2   c  calculates the fee to be charged for the image forming operations performed in accordance with the input command and the balance of the present amount of money remaining in the EM IC card  4  and the fee for the requested image forming operations. In the above calculations, if the user is applied with any discount described above, such a discount is taken into account. Further, in Step S 48 , the CPU  2   c  also displays the calculation result through the operation panel unit  7 .  
         [0086]    In Step S 49 , the CPU  2   c  checks if the user has put in a confirmation code for further proceeding with the operation. If the user has put in a code (i.e., a cancel code) than the confirmation code and the check result of Step S 49  is NO, the process returns to Step S 45  to repeat the above-described operations. If the user inputs the confirmation code and the check result of Step S 49  is YES, the process proceeds to Step S 50 . In Step S 50 , the CPU  2   c  determines if the present amount of money remaining in the EM IC card  4  is greater than the fee for the demanded operations as a result of the balance calculation performed in Step S 48 . If the present amount is not greater than the fee for the demanded operations and the determination result of Step S 50  is NO, the CPU  2   c  displays an amount of balance due through the operation panel unit  7 , in Step S 51 , and returns to Step S 45  to allow the user to change the command to input.  
         [0087]    If the present amount is greater than the fee for the demanded operations and the determination result of Step S 50  is YES, the CPU  2   c  performs a money collection process for collecting the money from the EM IC card  4  in accordance with the calculations performed in Step S 48 . In this process, the monetary information stored in the memory  4   d  of the EM IC card  4  is rewritten in accordance with the calculations performed by the CPU  2   c  of the control unit  2  in the image forming apparatus  1  in Step S 48 . In Step S 52 , the CPU  2   c  starts to perform the operation demanded by the user in Step S 45  and instructs the CPU  4   c  of the EM IC card  4  to update the history information. Further, in Step S 52 , the CPU  2   c  send the history information to the host computer  21  of the control center  20  so as to update the data base at the address ADR# 005 . In Step S 54 , upon a completion of the demanded operation, the CPU  2   c  displays the completion of the demanded operation through the operation panel unit  7  and sends the monetary information to the host computer  21 . The process then ends.  
         [0088]    Referring to FIG. 11, an exemplary procedure of the control operation performed by the monetary information control system  100  when the process cartridge  3  is exchanged in the image forming apparatus  1  is explained. It is assumed that the image forming apparatus  1  is out of toner and therefore the process cartridge  3  containing a toner tank has been exchanged, for example. As another example, when the photoconductive member  12  is exchanged because its life time is ended, the procedure similar to the above will be taken place.  
         [0089]    In Step S 55  of FIG. 11, the CPU  2   c  checks if the new process cartridge  3  is installed in the image forming apparatus  1 . The check of Step S 55  forms a NO loop for holding the process until the new process cartridge  3  is installed. This process may be performed each power-on time, each time a toner end is detected or a life end of the photoconductive member is detected, or each time after some action is taken based on the above detection.  
         [0090]    If the new process cartridge  3  is installed and the check result of Step S 55  is YES, the CPU  2   c  receives the monetary information from the EM unit  5  of the new process cartridge  3 , in Step S 56 . The CPU  2   c  mainly receives the property information from the monetary information. The property information includes a part number, a manufacturing number, and functional information which identify the process cartridge  3 . The property information further includes price information indicative of a price of the process cartridge  3 .  
         [0091]    In Step S 57 , the CPU  2   c  verifies the property information received from the new process cartridge  3  with the property information of the previous process cartridge  3  contained in the configuration information which is stored in the memory  2   d  and determines if the verification is successfully completed. If the verification is successfully completed and the determination result of Step S 57  is YES, the process proceeds to Step S 65  in which the CPU  2   c  moves into the regular routine. Then, the process ends.  
         [0092]    If the property information of the new process cartridge  3  is not properly verified with the property information of the previous process cartridge  3  and the determination result of Step S 57  is NO, the CPU  2   c  sends an inquiry on the property information of the new process cartridge to the host computer  21  of the control center  20 , in Step S 58 . In Step S 59 , the CPU  2   c  checks in the monetary information if the fee for the exchange of the process cartridge  3  is paid. If the fee is not paid and the check result of Step S 59  is NO, the process proceeds to Step S 60  in which the CPU  2   c  displays a message indicating that the process cartridge  3  has been exchanged and the user is requested to insert the EM IC card  4  to pay for the process cartridge  3 .  
         [0093]    In Step S 61 , the CPU  2   c  performs a money collection process. In the money collection process, the CPU  2   c  checks if the EM IC card  4  is inserted. If the EM IC card  4  is inserted, the CPU  2   c  receives the monetary information from the card  4 . Then, the CPU  2   c  displays the card owner&#39;s name and the present amount of money remaining in the card  4 . The CPU  2   c  calculates any discount in accordance with the history information. Then, the CPU  2   c  displays a message indicating that the process cartridge  3  has been exchanged and the calculated fee is collected, and wait for an input of a confirmation code by the user. If the process is cancelled at this time, the CPU  2   c  stops the process and proceeds to Step S 62 . If the process is confirmed, the CPU  2   c  determines if the calculated fee can be collected from the present amount of money remaining in the EM IC card  4  and, if the calculated fee is determined as can be collected, the CPU  2   c  performs the collection and proceed to Step S 52 .  
         [0094]    In Step S 62 , the CPU determines if the process is cancelled in the above money collection process. If the process is cancelled and the determination result of Step S 62  is YES, the process ends. If the process is not cancelled and the determination result of Step S 62  is NO, the process proceeds to Step S 63  in which the CPU  2  updates the configuration information in the memory  2   d  and displays a message indicating that the exchange of the process cartridge  3  has been completed. In Step S 64 , the CPU  2   c  checks if the user responds to the above display by inputting a confirmation code. The check of Step S 64  forms a NO loop to wait until the user input the confirmation code. If the user inputs the confirmation code and the check result of Step S 64  is YES, the CPU  2   c  moves into the regular routine. Then, the process ends.  
         [0095]    In the check of Step S 59 , there are two cases which lead to a YES result. In a first case, the new process cartridge  3  is a recycled process cartridge  3  and the user has paid for it before the exchange operation. For such a case, the data base  22  in the host computer  21  may be generated based on the property information which is used for the registration of the property information to the EM unit  5  of the process cartridge  3 . Since the history information such as the recycle history information can be included in the property information registered in the EM unit  5 , the data base  22  thus can include such recycle history information. Thereby, it becomes possible for the CPU  2   c  by sending an inquiry of the monetary information to the host computer  21  to recognize that the payment for the process cartridge  3  is settled.  
         [0096]    In a second case, the user holds a plurality of process cartridges  3  for some reason and uses it by exchanging one after another. For such a case, the configuration information for the image forming apparatus  1  registered in the data base  22  of the host computer  21  is arranged to includes a plurality of the identification information. When one of the process cartridges  3  is subjected to the recycle process, the identification information of such process cartridge  3  may be deleted from the configuration information for the image forming apparatus  1  registered in the data base  22 .  
         [0097]    Referring to FIG. 12, an exemplary procedure of the control operation performed by the monetary information control system  100  when the process cartridge  3  is exchanged for the recycle process in the image forming apparatus  1  is explained. It is assumed that the life time of the process cartridge  3 , for example, is ended and therefore the process cartridge  3  is exchanged and is subjected to the recycle process. As another example, when the photoconductive member  12  is exchanged because its life time is ended, the procedure similar to the above will be taken place.  
         [0098]    In Step S 70  of FIG. 12, the CPU  2   c  of the control unit  2  in the image forming apparatus  1  checks if the process cartridge  3  needs to be exchanged. The check of Step S 70  forms a NO loop to continue until the CPU  2   c  detects that the process cartridge  3  should be exchanged. If the process cartridge  3  should be exchanged and the check result of Step S 70  is YES, the CPU  2   c  displays the need for a recycle process, in Step S 71 . In Step S 72 , the CPU  2   c  checks if the user inputs a confirmation code for confirming the performance of the recycle process. If the user inputs a code other than the confirmation code and the check result of Step S 72  is NO, the CPU  2   c  ends the process. If the user inputs the confirmation code and the check result of Step S 72  is YES, the CPU  2   c  proceeds to Step S 73  and displays a message indicating that the recycle of the process cartridge  3  has proceeded. At the same time, the CPU  2   c  sends a request for a recycle process to the host computer  21 .  
         [0099]    In Step S 74 , upon a receipt of the recycle request sent from the image forming apparatus  1 , the host computer  21  generates a plan for collecting the process cartridge  3  from the image forming apparatus  1  based on the information of a location of the image forming apparatus  1  and a location of the recycle work shop read from the history information and a schedule of transportation (e.g., a truck) for collection. At this time, the host computer  21  can search an inventory of other consumable items or parts held at the site of the image forming apparatus  1  and calculate when these consumable items or parts are in short supply and should be replenished. Therefore, it is possible for the host computer  21  to arrange a delivery of additional consumable items or parts, if needed as a part of the above collection plan.  
         [0100]    In Step S 75 , the host computer  21  sends the monetary information generated as the money information or the property information, and the above collection plan to the image forming apparatus  1 . As described above, the monetary information includes the history information, particularly, the recycle information, the fee information related to the recycle process, the information of an available collection company, and so on.  
         [0101]    In Step S 76 , upon a receipt of the monetary information and the collection plan, the CPU  2   c  of the control unit  2  in the image forming apparatus  1  registers the monetary information to the EM unit  5 . In Step S 77 , the CPU  2   c  displays through the operation panel unit  7  the plan for the collection of the process cartridge  3  and a message indicating that the arrangement of the recycle process for the process cartridge  3  is completed and therefore the user can proceed with the exchange of the process cartridge  3 .  
         [0102]    In this way, the monetary information control system  100  can improve the user convenience in handling the image forming apparatus  1  by implementing the automatic arrangement of the recycle process and the automatic payment process for the recycle process.  
         [0103]    In addition, the above monetary information control system  100  can handle an automatic repair call to the control center  20  or to a specific repair center. In this case, it may be useful to cumulatively store the information indicative of machine usage such as a number of prints per day, measurement of the internal and environmental temperature and humidity, and so on in the data base  22  of the host computer  21  in the control center  20 . The record of the above accumulative information can be used for repair as well as preventive maintenance.  
         [0104]    The disclosed system and process may be conveniently implemented using a conventional general purpose digital computer programmed according to the teaching of the present specification, as will be apparent to those skilled in the computer art. Appropriate software coding can readily be provided by skilled programmers based on the teachings of the present disclosure, as will be apparent to those skilled in the software art. Various implementation may also use application specific integrated circuits and/or an appropriate network of conventional component circuits, as will be readily apparent to those skilled in the art.  
         [0105]    Numerous additional modifications and variations are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present application may be practiced otherwise than as specifically described herein.  
         [0106]    This application claims priority to Japanese patent application No. JPAP2000-035485 filed on Feb. 14, 2000 in the Japanese Patent Office, the entire contents of which are hereby incorporated by reference.
