The present invention generally relates to image forming apparatuses and, more particularly, to an image forming apparatus such as a copy machine provided with a function to manage external apparatuses.
Recently, a so-called complex copy machine, which is provided with a facsimile function, has prevailed in image forming apparatuses such as a copy machine. A facsimile-function-added copy machine is naturally provided with a communication circuit connected to an external line. If an image forming apparatus is provided with a function to manage a plurality of external apparatuses, it is convenient since the state of the external apparatuses can be unitarily managed through communication between the image forming apparatus and a central station.

FIG. 2 is an illustration of a structure of software, which the control part 6 performs. In the software performed by the control part 6, a plurality of functional processes are concurrently performed based on a multi-task general operating system (OS) such as UNIX�. In FIG. 2, various application processes (NRS, PRINT, COPY, FAX, SCAN), which the control part 6 performs, are indicated in the uppermost layer. A plurality of service processes (WSC, RCS, ECS, MCS, OCS, FCS, NCS) are provided between the application process and the general OS. The lowermost layer in FIG. 2 indicates a hardware structure.
NCS (Network Control Service) functions as the communication part 5 among the above-mentioned service processes. Additionally, MCS (Memory Control Service) manages read and write operations of the memory part 4. Moreover, WCS (Web Control Service) realizes a Web server part 18 and a Web client part 23. Operations of other parts of the control part 6 are realized by NRS_APL (NRS_Application) of the application process, and RCS (Remote Control Service) of the service process.
The managed object specifying part 7 of the image forming apparatus C according to the present embodiment is provided with a managed object limiting part 12, which determines or select apparatuses to be set as the managed object apparatuses K from among apparatuses that are communicable through the communication part 5.
The managed object limiting part 12 is provided with a function, as one of functions to be achieved by the managed object limiting part 12, to discriminate apparatuses, which are set as the managed object apparatuses K, prior to acquire discrimination information of the apparatuses which are communicable through the communication part 5, from the apparatuses concerned.
In the present embodiment, in addition to the image forming part 1, a scanner part 13 which reads a character image on a medium and a character recognition part 14 which converts the character image read by the scanner part 13 into character data are provided so as to realize the function to select apparatuses to be set as the managed object apparatuses K. The managed object limiting part 12 acquires the discrimination information S of the apparatuses that are set as the managed object apparatuses K through the scanner part 13 and the character recognition part (optical character reader: OCR) 14. The discrimination information S is printed on a medium and read by the canner part 13 and converted into data by the character recognition part 14. The managed object limiting part 12 stores the discrimination information S in the memory part 4 as data for specifying the managed object apparatuses K.
Moreover, the managed object limiting part 12 is provided with an external file acquisition function 15 so as to acquire an external file on which the discrimination information S of the apparatuses made into the managed object apparatuses K according to the external file acquisition function 15. The managed object limiting part 12 reads the data of the discrimination information S of the apparatuses from the acquired external file concerned, and is capable of storing the data of the discrimination information S of the apparatuses in the memory part 4 as the discrimination information S for specifying the managed object apparatuses K. Here, the external file may be acquired from a recording medium on which the external file is recorded by connecting the recording medium to an interface of the image forming apparatus. Alternatively, data of the external file may be acquired through the communication part 5.
Moreover, the managed object limiting part 12 is provided with a function to limit the apparatuses that are set as the managed object apparatuses K after acquiring the discrimination information of the apparatuses which are communicable through the communication part 5 from the apparatuses concerned.
That is, the managed object limiting part 12 selects the apparatuses set as the managed object apparatuses K according to a managed object apparatus individually selecting operation performed on the input part 2, after acquiring the discrimination information of the apparatuses which are communicable through the communication part 5 from the apparatuses concerned. The managed object limiting part 12 stores the discrimination information S of the selected apparatuses in the memory part 4 as discrimination information S for specifying the managed object apparatuses K. The managed object apparatus individually selecting operation is an operation to make a selection by displaying a list of the discrimination information of the apparatuses on the display part 3, indicating only the discrimination information of the apparatuses made into the managed object apparatuses K by an operation of the input part 2 by reversing display, and pressing a determination button.
The managed object limiting part 12 also has a sorting function 16 to sort and display the discrimination information of the apparatuses according to items consisting of the discrimination information when causing the display part to display the discrimination information of the apparatuses. The items consisting the discrimination information include type information and manufacturer information of the apparatuses.
Therefore, when causing the display part 2 to display the discrimination information of the apparatuses, the managed object limiting part 12 can sort and display the discrimination information for each manufacturer and for each type of apparatuses.
Moreover, the managed object limiting part 12 is capable of acquiring the discrimination information of the apparatuses, which are communicable through the communication part 5, and storing the acquired discrimination information in the memory part 4. Then, the managed object limiting part 12 generates a list of kinds of elements contained in each of the items, which constitute the acquired discernment information. The managed object limiting part 12 causes the display part 3 to display the list, and receives from the input part 2 an instruction of selection of the kind in the list which is displayed by the display part 3. Then, the managed object limiting part 12 stores the discrimination information containing the selected kind in the memory part 4 as the discrimination information S of the apparatuses, which are set as the managed object apparatuses K.
FIG. 3 shows an example of the discrimination information S of the managed object apparatuses and an example of the state information. In FIG. 3, Model/Number, IP address, Media Access Control (MAC) Address, and Manufacturer Name correspond to the discrimination information S of the managed object apparatuses K, and are acquired as MIB information. In the Model/Number, a part followed by a hyphen represents a model number, and there may be a case in which two or more Model/Numbers have the same model number. The number after the hyphen is a serial number, which does not duplicate in the same model. Therefore, the Model/Number can uniquely identify each apparatus. As the state information, an abnormal communication time (abnormality generated time) and a normal communication time (return to normal time) are managed. It can be judged that the apparatus is functioning normally at present when the normal communication time is later than the abnormal communication time. A report day is a date on which a notification of predetermined state information is sent from the image forming apparatus to the center apparatus 100.
For example, when there are two each of apparatuses of manufacturers A and B, the two kinds, i.e., manufactures A and B, are displayed on the display part 3 as elements contained in the item of manufacture information. Then, when the manufacturer A is selected according to the instruction input through the input part 2, the two apparatuses of which item of manufacture information indicates the manufacture A are selected as managed object apparatuses.
FIG. 4 shows apparatus information required for connecting the image forming apparatus C to the center apparatus 100. The apparatus information is also stored in the memory part 4, and the telephone number and conditions of telephone calling of the center apparatus 100 are specified beforehand. In order to connect the image forming apparatus C to the center apparatus 100, the connection can be made through a public telephone network or through LAN and the Internet.
The managed object limiting part 12 causes the display part 3 to display discrimination information including the selected kind before storing in the memory part 4 the discrimination information of the apparatuses set as managed objects. Then, the managed object limiting part 12 receives from the input part 2 a confirmation input as to whether the apparatuses corresponding to the selected discrimination information are appropriate for the manages objects, and stores the information in the memory part 4 as the discrimination information S of the managed object apparatuses K.
As mentioned above, the manufacturer information and model information of the apparatuses concerned are included in the items, which constitute the apparatus discrimination information. When acquiring the apparatus discrimination information from the apparatuses concerned, the managed object limiting part 12 uses a Simple Network Management Protocol (SNMP), and the discernment information consists of items of Management Information Base (MIB).
FIG. 5 shows an example of information representing communication conditions of each apparatus. The information representing communication condition is also stored in the memory part 4. In the information, with respect to the apparatus corresponding to the model information 1234, it is specified that a counter value (a number of printing pages) is acquired in the form of MIB by SNMP and alarm information is acquired in the form of XML by HTTP.
The managed object specifying part 7 having the managed object limiting part 12, is activated by an operation to input part 2 or a remote activation part 17. The remote activation part 17 starts an operation of the managed object specifying part 7 when receiving a start command for the managed object specifying part 7 through the communication part 5 from external apparatuses (portable terminals CE of a customer engineer and/or customer terminals PC).
Here, the method to limit the managed object apparatuses by the managed object limiting part 12 can be selected previously from among the above-mentioned limiting methods of a plurality of managed objects through an operation to the input part 2 or a remote operation made by an external apparatus.
In the present embodiment, a request to the center apparatus 100 and reception of information from the center apparatus 100 are performed according to SOAP (Simple Object Access Protocol).
Moreover, the information providing part 11 is provided with a Web server part 18 which provides to an external apparatus the state information J for each managed object apparatus stored in the memory part 4 through the communication part 5.
Moreover, the apparatus monitoring part 9 acquires the abnormality generated time and the return to normal time as the state information J for each managed object apparatus, and stores the acquired time information in separate memory areas, respectively.
Additionally, the apparatus monitoring part 9 has an abnormality determining part 19 which determines that a managed object apparatus having a return to normal time later than an abnormality generated time is currently working in a normal state, and determines that a managed object apparatus having a return to normal time earlier than an abnormality generated time is currently working in an abnormal state. Moreover, the apparatus monitoring part 9 has a schedule functional part 21 which acquires the above-mentioned state information periodically at a preset time.
Moreover, the memory part 4 stores a first acquisition procedure for acquiring state information J from the managed object apparatuses K which should be managed through the communication part 5 and a second acquisition procedure for acquiring the state information J of the image forming apparatus as one of the managed object apparatuses. Therefore, the apparatus monitoring part 9 performs the first acquisition procedure when acquiring the state information from the managed object apparatuses K which should be managed through the communication part 5, and performs the second acquisition procedure when acquiring the state information of the image forming apparatus itself.
Upon reception of an information providing request through the communication part 5 from a portable terminal CE of a customer engineer or a customer terminal PC which is an external apparatus, the Web server part 18 reads the state information J according to the request concerned from the memory part 4, and transmits the state information J to the portable terminal CE or the customer terminal PC which made the request.
The control part 6 is provided with self review part 22 which reads the state information J from the memory part 4 according to an operation of the input part 2 and displays the state information J concerned on the display part 3. Moreover, the control part 6 is provided with a Web client part 23 which sends a review request of the state information to an external image forming apparatus via the communication part 5, and displays the state information received from the external Web server part concerned through the communication part 5 on the display part 3.
Here, in FIG. 1, the image forming part 1 comprises mechanisms and sensors necessary for performing electro-photographic printing. The input part 2 is a part which has an input means having a touch key panel or buttons. The display part 3 is constituted by a liquid crystal display panel or the like. The memory part 4 includes a random access memory (RAM), a read only memory (ROM), a hard disc drive (HDD), etc. as a memory. The communication part 5 includes a modem connectable to the center apparatus 100 through a public telephone network and a protocol interface which communicates with managed object apparatuses through LAN. The control part 6 comprises a central processing unit (CPU) and an application specification integrated circuit (ASIC). The control part 6 can carry out parallel processing of the processes for realizing the function of each part contained in the control part 6 on the multitask general-purpose operating system.
A description will now be given of an operation of the image forming apparatus C according to the present embodiment.
First, the managed object specifying part 7 is activated by operating the input part 2, the portable terminal CE or the customer terminal PC. When the managed object specifying part 7 is activated, the managed object limiting part 12 is activated so as to store the identification information S in the memory part 4 in accordance with a previously selected limiting method of the managed object apparatuses K.
Then, the apparatus correspondence condition acquiring part 8 is activated so as to send the discrimination information of the managed object apparatuses stored in the memory part 4 to the center apparatus 100 through the communication part 5.
Upon reception of the discrimination information S regarding the managed object apparatuses, the center apparatus 100 searches for a communication condition for each apparatus corresponding to the discrimination information concerned, and sends the information regarding the communication condition to the image forming apparatus C.
Upon reception of the information regarding communication condition from the center apparatus 100, the apparatus correspondence communication condition acquiring part 8 relates the communication condition J concerned to the discrimination information S of the corresponding managed object apparatuses, and stores the information in the memory part 4.
Then, the apparatus monitoring part 9 is activated so as to acquire the state information of each managed object apparatus K and the image forming apparatus itself and store the state information in the memory part 4.
FIG. 6 shows a procedure carried out by the image forming apparatus C to collect logs from one of the managed object apparatuses K. It should be noted that arrows in the figure indicate a flow of commands, requests and data, and numbers represents sequence thereof. When NRS starts log collection according to schedule service of RCS, the managed object apparatus K from which logs should be collected is specified in RCS, and communication conditions corresponding to the apparatuses are identified and a request is sent to the managed object apparatus K in accordance with SOAP. The managed object apparatus K receives the request according to SOAP, and RCS sends to MRS a request of outputting the logs. NRS of the managed object apparatus K sends a command through MCS to read the logs and transfer the logs to RCS. The read log is sent to the image forming apparatus C by NCS. Upon reception of the logs by NCS, the image forming apparatus C causes MCS to store the logs in the memory part 4 as state information of the managed object apparatus concerned.
Then, when a review request of the state information J is sent to the information providing part 11 and the request made through the input part 2, the self review part 22 is operated and the requested state information is displayed on the display part 3. On the other hand, when the review request is made by the portable terminal CE or the customer terminal PC, the Web server part 18 is operated and the state information J stored in the memory part 4 is transmitted to the portable terminal CE or the customer terminal PC which made the request.
Moreover, when it is desirable to receive information provided by an external Web server, the Web client part 23 is activated so as to review the information provided by the external Web server part by displaying the information on the display part 3.
FIG. 7 shows a procedure for reviewing through a portable terminal CE state information managed by the image forming apparatus C. It should be noted that, in the figure, arrows indicate a flow of commands, requests and data, and numbers attached to the arrows represents their sequence. When a request is made through HTTP according to a Web client function of the portable terminal, the state information read by MCS is transferred to WCS in the image formation apparatus C, and, then, the state information is sent to the portable terminal CE according to HTTP. Thus, the state information can be reviewed through the Web client part of the portable terminal.
FIG. 8 shows a procedure for reviewing information held by the center apparatus through the portable terminal CE. In this case, a request (HTTP) from the portable terminal CE is processed by the image forming apparatus C, and, then, the information providing request (SOAP) is sent from the image forming apparatus C to the center apparatus 100. The information provided from the center apparatus 100 to the image forming apparatus C according to SOAP is transferred from the image forming apparatus C to the portable terminal CE according to HTTP. The thus-provided image can be reviewed through the Web client function of the portable terminal CE.
FIG. 9 shows a procedure of sending a notification of an abnormality generated in the managed object apparatus K to the customer terminal PC and the center apparatus 100. The state information of the managed object apparatus K is periodically acquired by schedule service of RCS according to SOAP, and is accumulated in the memory part 4 of the image formation apparatus C by MCS. If abnormality of the managed object apparatus K is detected based on the state information, an abnormality notification function is activated so as to send an abnormality notification to the center apparatus 100 according to SOAP, and an electronic mail is sent to the customer terminal PC according to SMTP. In the center apparatus 100, a predetermined abnormality processing is performed based on the received abnormality notification. In the customer terminal PC, an electronic mail which notifies occurrence of the abnormality can be reviewed through an interface such as the Web client function.
FIG. 10 is an example of a screen for reviewing the state information by the portable terminal CE or the customer terminal PC. In the example shown in FIG. 10, the state information is displayed with a model and a serial number to which an installation place of the apparatus, date and time of occurrence of the abnormality and a contact number of a person in charge are related.
FIGS. 11A and 11B show examples of a procedure for reviewing the state information. If the discrimination information of the managed object apparatuses is elected as shown in FIGS. 11A and 11B, CGI of a Web page may be prepared so that the list of abnormal logs of the selected apparatus is displayed.
According to the present embodiment explained above, the setting of the managed object apparatuses K to the image forming apparatus C can be easily performed according to the function of the managed object specifying part 7. Moreover, since the apparatus correspondence communication condition acquiring part 8 prepares an appropriate communication condition for each managed object apparatus, the state information can be properly acquired from various managed object apparatuses K. Moreover, according to the function of the information providing part 11, the state information can be reviewed on the display part 3 of the image forming apparatus C or through the external terminals CE and PC, and, thereby, the state information of a plurality of apparatuses can be checked without moving. Moreover, a communication line between the image forming apparatus C and the center apparatus 100 is always maintained due to the managing function of the managed object apparatuses being incorporated into the image forming apparatus C, and there is a small risk of unexpected accident. Thus, a stable management can be achieved.
The present application is based on Japanese priority applications No. 2002-118849 filed Apr. 22, 2002 and No. 2003-109350 filed Apr. 14, 2003, the entire contents of which are hereby incorporated by reference.
