     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Embodiments of an image forming apparatus as an information processing apparatus will be described in detail hereinafter with reference to the attached drawings. An example applied to the image forming apparatus as the information processing apparatus will be described below, but the applicable devices are not limited to the image forming apparatus. 
     First Embodiment 
     First, a system configuration using an image forming apparatus according to the present embodiment will be described.  FIG. 1  is a system configuration diagram of the image forming apparatus according to the first embodiment. As illustrated in  FIG. 1 , the image forming apparatus  1  is connected to an order receiving server  50  via a network  11  such as the Internet. 
     Next, a hardware configuration of the image forming apparatus  1  will be described using  FIG. 2 .  FIG. 2  is a hardware configuration diagram of the image forming apparatus according to the first embodiment. As illustrated in  FIG. 2 , the image forming apparatus  1  is provided with a main body  110  which is capable of realizing various functions such as a copy function, a scanner function, a facsimile function, and a printer function, and an operation unit  120  which receives an operation from a user. Receiving the operation from the user is a concept which includes receiving information (including signals indicating a coordinate value of a screen, etc.) input in response to the operation of the user. 
     The main body  110  and the operation unit  120  are connected so as to communicate mutually via a dedicated communication path  300 . The communication path  300  may be, for example, of universal serial bus (USB) standard, or an arbitrary wired or wireless standard. 
     The main body  110  is capable of performing the operation in response to the operation received at the operation unit  120 . In addition, the main body  110  can communicate with an external device such as a client personal computer (PC) and can perform the operation in response to an instruction received from the external device. 
     First, the hardware configuration of the main body  110  will be described. As illustrated in  FIG. 2 , the main body  110  includes a central processing unit (CPU)  111 , a read only memory (ROM)  112 , a random access memory (RAM)  113 , a hard disk drive (HDD)  114 , a communication interface (I/F)  115 , a connection interface (I/F)  116 , and an engine unit  117 , which are connected mutually via a system bus  118 . 
     The CPU  111  totally controls the operation of the main body  110 . The CPU  111  controls the whole operation of the main body  110  by executing a program stored in the ROM  112 , the HDD  114 , etc., using the RAM  113  as a work area, thereby realizing various functions mentioned above such as the copy function, the scanner function, the facsimile function, and the printer function. 
     The communication I/F  115  is an interface for connecting to the network  11 . The connection I/F  116  is an interface for communicating with the operation unit  120  via the communication path  300 . 
     The engine unit  117  is a piece of hardware which performs processes other than versatile information processing and communication in order to realize the copy function, the scanner function, the facsimile function, and the printer function. The image forming apparatus  1  is provided with: for example, a scanner unit (image reading unit) which reads an image of the document by scanning; a plotter unit (image forming unit) which performs printing on a sheet material such as paper; and a facsimile unit which performs facsimile communication. In addition, a specific option such as a finisher for sorting a printed sheet material or an automatic document feeder (ADF) for feeding document automatically may be provided. 
     Next, the hardware configuration of the operation unit  120  will be described. As illustrated in  FIG. 2 , the operation unit  120  is provided with a CPU  121 , a ROM  122 , a RAM  123 , a flash memory  124 , a communication I/F  125 , a connection I/F  126 , an operation panel  127 , and an external connection I/F  128 , which are connected mutually via a system bus  129 . 
     The CPU  121  totally controls the operation of the operation unit  120 . The CPU  121  controls the whole operation of the operation unit  120  by executing a program stored in the ROM  122 , the flash memory  124 , etc., using the RAM  123  as a work area, thereby realizing various functions mentioned below such as displaying information (image) in response to an input received from the user. 
     The communication I/F  125  is an interface for connecting to the network  11 . The connection I/F  126  is an interface for communicating with the main body  110  via the communication path  300 . The external connection I/F  128  is an interface for connecting to the external device which is connected to the image forming apparatus  1 . 
     The operation panel  127  displays various information (for example, information in response to the operation received, information indicating operation condition of the image forming apparatus  1 , and information indicating setting condition) in addition to receiving various inputs in response to the operation from the user. In this example, the operation panel  127  includes a liquid crystal display (LCD) mounted with a touch panel function, but is not limited thereto. For example, the operation panel  127  may include an organic EL display device mounted with the touch panel function. Moreover, an operation unit for a hardware key, etc., and a display unit for a lamp, etc. may be provided in addition to or in place of the above. 
     Next, a software configuration of the image forming apparatus  1  will be described.  FIG. 3  is a schematic diagram illustrating an example of the software configuration of the image forming apparatus according to the first embodiment. As illustrated in  FIG. 3 , the main body  110  includes an application layer  101 , a service layer  102 , and an OS layer  103 . The entities of the application layer  101 , the service layer  102 , and the OS layer  103  are various pieces of software stored in the ROM  112 , the HDD  114 , etc. The CPU  111  executes these pieces of software, thereby providing various functions. 
     The software of the application layer  101  is application software (hereinafter sometimes simply referred to as application) for providing a predetermined function by operating a hardware resource. Examples of the applications include a copy application for providing the copy function, a scanner application for providing the scanner function, a facsimile application for providing the facsimile function, and a printer application for providing the printer function. 
     The software of the service layer  102  is interposed between the application layer  101  and the OS layer  103 , and is the software for providing the application with an interface for utilizing the hardware resource included in the main body  110 . More specifically, the software provides the functions of receiving the operation request and arbitrating the operation request to the hardware resource. The operation request which the service layer  102  receives is considered to be a request of reading by a scanner, printing by a plotter, or the like. 
     The interface function of the service layer  102  is provided not only for the application layer  101  of the main body  110 , but also for the application layer  201  of the operation unit  120 . That is, the application layer  201  (application) of the operation unit  120  can also realize the function utilizing the hardware resource (for example, the engine unit  117 ) of the main body  110  via the interface function of the service layer  102 . 
     The software of the OS layer  103  is the basic software (operating system) for providing a basic function of controlling the hardware included in the main body  110 . The software of the service layer  102  converts a use request of the hardware resource from the various applications into a command which the OS layer  103  can interpret and passes it to the OS layer  103 . Then, by executing the command by the software of the OS layer  103 , the hardware resource performs the operation according to the request of the application. 
     Similarly, the operation unit  120  includes an application layer  201 , a service layer  202 , and an OS layer  203 . The application layer  201 , the service layer  202 , and the OS layer  203  included in the operation unit  120  have the same layered structures as those of the main body  110 . However, the function provided by the application of the application layer  201  and a variety of the operation requests receivable at the service layer  202  are different from those of the main body  110 . The application of the application layer  201  may be the software for providing a predetermined function by operating the hardware resource included in the operation unit  120 . However, the application of the application layer  201  is the software for mainly providing a user interface (UI) function for operating and displaying functions (the copy function, the scanner function, the facsimile function, and the printer function) included in the main body  110 . 
     In the present embodiment, the software of the OS layer  103  of the main body  110  and the software of the OS layer  203  of the operation unit  120  differ from each other in order to keep independence of functions. That is, the main body  110  and the operation unit  120  operate independently of each other by separate operating systems. For example, Linux (registered trademark) can be used as the software of the OS layer  103  of the main body  110 , and Android (registered trademark) can be used as the software of the OS layer  203  of the operation unit  120 . 
     As described above, in the image forming apparatus  1  of the present embodiment, the main body  110  and the operation unit  120  operate by different operating systems. Therefore, the communication between the main body  110  and the operation unit  120  is performed as communication between different devices, not as inter-process communication within the common device. An operation to transmit information (content of the instruction from the user), received by the operation unit  120 , to the main body  110  and an operation of the main body  110  to notify the operation unit  120  of an event are included in this communication. Here, functions of the main body  110  can be used by command communication to the main body  110  performed by the operation unit  120 . In addition, the event, of which the operation unit  120  is notified by the main body  110 , includes executing state of the operation by the main body  110  and the content set for the main body  110 . 
     In addition, in the present embodiment, power supply to the operation unit  120  is made from the main body  110  via the communication path  300 . Therefore, power supply controls of the operation unit  120  and the main body  110  can be conducted separately (independently). 
     Next, a functional configuration of the image forming apparatus  1  will be described.  FIG. 4  is a block diagram illustrating the functional configuration of software of the image forming apparatus  1 . As illustrated in  FIG. 4 , an operation display control unit  10  controls a panel display for information operation provided on the image forming apparatus  1 . In addition, the operation display control unit  10  receives operation input from the user and reports an operation content received to a processing unit  20 . The processing unit  20  controls the operation of the image forming apparatus  1  in response to the input from the user. A communication unit  30  controls data exchanging with external via the communication I/F  115 . A storage control unit  40  performs processing of storing the consumables list, corresponding to device number information of the device or corresponding to the device, on the ROM  112  or the HDD  114 , which is a non-volatile memory. The above-described functions may be realized by the software or the hardware such as an electronic circuit. 
     Next, the utilization status of ordering consumables from this image forming apparatus  1  will be described using  FIGS. 5A and 5B . As illustrated in  FIGS. 5A and 5B , the consumables list available in and corresponding to the image forming apparatus  1  has been stored in the image forming apparatus  1 . A customer selects a product from the consumables list displayed at the panel by the operation display control unit  10  and performs an ordering procedure. The image forming apparatus  1 , which has received the ordering procedure, sends the order information to an order receiving server  50  via the network. 
       FIG. 6  is a sequence diagram illustrating a processing flow of ordering consumables according to the present embodiment.  FIG. 6  is a processing flow in a state where the image forming apparatus  1  is connected to the network. As illustrated in  FIG. 6 , at first, a process is started by the user touching an icon of an application for ordering consumables via the operation display control unit  10  (Step S 1 ). Next, the processing unit  20  starts up the application (Step S 2 ). The processing unit  20  sends the instruction to the communication unit  30  to connect to the order receiving server  50  via the application started up (Step S 3 ). The communication unit  30  performs the connection processing with the order receiving server  50 . When the communication unit  30  succeeds in the connection with the order receiving server  50  (Step S 4 ), the communication unit  30  receives a notification of successful connection (Step S 5 ). 
     Upon receiving the notification of successful connection, the communication unit  30  sends the notification to the application which the processing unit  20  starts up. Then the processing unit  20  requests the storage control unit  40  to extract the device number information (Step S 6 ). Upon receiving a request of acquiring the device number information from the processing unit  20 , the storage control unit  40  acquires the device number information from the non-volatile memory (ROM  112 , HDD  114 ) and sends it to the processing unit  20  (Step S 7 ). Upon receiving the device number information, the processing unit  20  requests to send the received device number information to the order receiving server via the communication unit  30  (Steps S 8 , S 9 ). Upon receiving the device number information (Step S 10 ), the order receiving server  50  sends the consumables list available in the image forming apparatus  1  which is identified by the device number information (Step S 11 ). The communication unit  30  receives the consumables list from the order receiving server  50  (Step S 12 ). The processing unit  20  sends an instruction to store the consumables list to the storage control unit  40  (Step S 13 ). The storage control unit  40  stores the consumables list (Step S 14 ). The processing unit  20  displays the consumables list (Step S 15 ). 
     The operation display control unit  10  displays the consumables list and receives an order instruction from the user (Step S 16 ). The processing unit  20  orders the order information to the order receiving server  50  via the communication unit  30  based on the order instruction received (Steps S 17 , S 18 ). The order receiving server  50  receives the order information (Step S 19 ). 
     Although  FIG. 6  illustrates the process when the network connection is possible,  FIG. 7  describes a processing flow in a circumstance where the network connection is impossible. The same numerals are provided for the same processes in  FIG. 6 , and the different parts will be described. As illustrated in  FIG. 7 , when the connection to the order receiving server  50  fails (Step S 21 ), the processing unit  20  sends an instruction to extract the consumables list to the storage control unit  40  (Step S 22 ). As the consumables list has been stored by the storage control unit  40  at the above-mentioned Step S 14 , the storage control unit  40  can extract the consumables list (Step S 23 ). 
     The processing unit  20  displays the consumables list and receives the order instruction from the user (Steps S 15 , S 16 ). The processing unit  20  requests the storage control unit  40  to store the order information (Steps S 24 , S 25 ). When the consumables list has not been stored in the image forming apparatus  1  in the state the network is not connected, that is, in the state of having never been connected to the network after the setup of the image forming apparatus  1 , a dialog illustrated in  FIG. 8  is displayed and the user is urged to confirm the network state. 
       FIG. 9  illustrates a process after the network connection is recovered, in which an order is received in the state where the network connection is disconnected. When the connection to the order receiving server  50  is successfully recovered (Step S 26 ), the processing unit  20  sends a command to acquire the order information stored by the storage control unit  40  from the storage control unit  40  (Step S 27 ). In this manner, the communication unit  30  monitors whether the connection to the order receiving server  50  has been recovered or not. Then, when the recovery is detected, the communication unit  30  sends the notification to the processing unit  20 . The storage control unit  40  acquires the order information from the non-volatile memory (ROM  112 , HDD  114 ) (Step S 28 ) and sends it to the processing unit  20 . 
     The above-described image forming apparatus  1  according to the present embodiment can receive the order from the consumables list already stored even in the state of being not connected to the network. Then, the received order information is sent to the order receiving server  50  when the network is reconnected. Therefore, the user can perform an order work even in the state of being not connected to the network. As the order is placed along with the recovery of the network connection, it is possible to order the consumables regardless of the connection state of the network. 
     Second Embodiment 
     In the first embodiment, the order information is sent instantly when the connection to the order receiving server  50  recovers. The second embodiment differs in performing a process, before sending the order information, of acquiring the consumables list from the order receiving server  50  and confirming if there is no difference between the consumables list from the order receiving server  50  and the consumables list stored in the device. The detailed process will be described below with reference to the drawings. 
     In  FIG. 10 , when the connection to the order receiving server  50  is recovered (Step S 26 ), the processing unit  20  requests the storage control unit  40  to extract the device number information (Step S 31 ). The storage control unit  40  acquires the device number information from the non-volatile memory (ROM  112 , HDD  114 ) and returns it to the processing unit  20  (Step S 32 ). The processing unit  20  sends the device number information to the order receiving server  50  via the communication unit  30  (Steps S 33 , S 34 ). Upon receiving the device number information (Step S 35 ), the order receiving server  50  sends the consumables list corresponding to the image forming apparatus  1  which is identified by the device number information (Step S 36 ). 
     The image forming apparatus  1  receives a new consumables list via the communication unit  30  (Step S 37 ), and the processing unit  20  instructs the storage control unit  40  to extract the previous consumables list already stored (Step S 38 ). When the consumables list is sent from the storage control unit  40  (Step S 39 ), the processing unit  20  compares a new consumables list acquired with the previous consumables list stored (Step S 40 ). 
       FIG. 11  is a flow after comparing the consumables lists. Then, the processing unit  20  determines whether there is a difference between the compared consumables lists (Step S 41 ). In a case where there is a difference, the processing unit  20  instructs the storage control unit  40  to update the consumables list to a new one (Steps S 42 , S 43 ). Then, the processing unit  20  instructs the storage control unit  40  to extract the order information which has been received in the state where the network connection cannot be connected as described above (Steps S 44 , S 45 ). Then the processing unit  20  confirms whether there are any changes in ordered products based on the acquired order information and the updated consumables list (Step S 46 ), and determines whether there are any changes (Step S 47 ). In a case where there are any changes, the processing unit  20  determines whether a substituting product has been set to the ordered product (Step S 51 ). As a method of setting the substituting product, a substitutable product is set for each product. For example, when a product is deleted from the consumables list, a substituting product is searched for and the substituting product for the original product is set. 
     When the substituting product has been set, the processing unit  20  confirms an operation setting when ordered consumables are changed (Step S 52 ). The operation setting when the ordered consumables are changed will be described later. On the other hand, in a case where there is no ordered product nor the substituting product, the processing unit  20  performs the cancellation processing of the order (Step S 53 ). In the cancellation processing, the storage control unit  40  deletes the order information (Step S 55 ) and sends the notification of cancellation to the operation display control unit  10  (Step S 54 ). 
     In a case where there are no changes in the ordered product in Step S 47 , the processing unit  20  sends the order information to the order receiving server  50  via the communication unit  30  (Steps S 48  to S 50 ). 
     In a case where there is no difference between the lists in Step S 41 , the processing unit  20  performs a process to extract the order information from the storage control unit  40  (Steps S 56 , S 57 ). Then, the processing unit  20  sends the extracted order information to the order receiving server  50  via the communication unit  30  (Steps S 58  to S 60 ). 
     Next, the details of the operation when the ordered consumables have been changed will be described using  FIG. 12 . First, the processing unit  20  confirms a process setting when the ordered consumables have been changed to the substituting product (Step S 61 ). When the setting necessarily requires a decision of the user, the processing unit  20  instructs the operation display control unit  10  to display the dialog to urge the user to do confirmation (Step S 62 ). The operation display control unit  10  receives the input from the user (Step S 66 ) and the processing unit  20  determines the content input from the user (Step S 67 ). When the input is the same as the order instruction, the processing unit  20  sends the order information to the order receiving server  50  via the communication unit  30  (Steps S 64 , S 71 , S 72 ). 
     When the input is an order accompanying changes in the order information, the processing unit  20  updates the order information and sends it to the order receiving server  50  (Step S 68 ). When the input is the cancellation of the order, the processing unit  20  cancels the order information (Step S 69 ), and deletes the order information via the storage control unit  40  (Step S 70 ). 
     In Step S 61 , when the change to the substituting product from the canceled product is in an item set in advance, in the present embodiment when a price is changed, the processing unit  20  determines whether there is a change in price when it is set that the user determines (Steps S 63 , S 65 ). The item set in advance may not necessarily be the price and may be other items, for example, capacity or size. If there is a change in price, the flow proceeds to Step S 62 . On the other hand, if there is no change in price, the flow proceeds to Step S 64 . When it is set that the order is necessarily conducted in Step S 61 , the flow proceeds to Step S 64 . 
     The image forming apparatus  1  of the present embodiment can perform a more flexible order work for consumables, when there is a change in the order information, such as ordering based on the setting and receiving the change from the user. 
     Third Embodiment 
     In the first embodiment, it is possible to receive an ordering procedure when the network is disconnected; however, it is necessary to connect to the server at least once to achieve it. As the network has never been connected, it results in an error when the consumables list is not stored. Therefore, the present embodiment is configured to store the available consumables list not from the network, but from an external medium (an external storage medium). 
       FIG. 13  illustrates a functional configuration diagram of an image forming apparatus  1  which newly includes an external medium managing unit  60 . The external medium managing unit  60  detects the connection of an external medium, for example, an SD card or a USB memory stick and passes data of the consumables list stored therein to a processing unit  20 . The device number information and the consumables list available in that device number as illustrated in  FIG. 14  are stored in the external medium. Then, as illustrated in  FIG. 15 , when the external medium is inserted into the device, the external medium managing unit  60  detects the insertion (Step S 81 ). When the insertion is detected, the processing unit  20  acquires the device number information via a storage control unit  40  (Steps S 82 , S 83 ). The processing unit  20  extracts the consumables list available in the device in light of the device number information of the device and stores the list (Steps S 84 , S 85 ). With this configuration, it will be possible to perform the ordering procedure without connecting to the network. 
     Although the above-described function of each unit of the image forming apparatus  1  is realized by executing the program stored in a storage device (for example, the ROM  112 , the HDD  114 , the ROM  122 , and the flash memory  124 ) by the CPU ( 111  or  121 ), it is not limited thereto, and at least a part of the function of each unit of the image forming apparatus  1  may be realized by a dedicated hardware circuit (for example, a semiconductor integrated circuit). 
     In addition, although in the above embodiments the main body  110  and the operation unit  120  operate independently of each other by the different operating systems, it is not limited thereto and the main body  110  and the operation unit  120  may operate by the same operating system. 
     In addition, the programs executed by the image forming apparatus  1  of the above-described embodiments may be provided by being stored in a computer-readable storage medium such as a CD-ROM, a flexible disk (FD), a CD-R, a digital versatile disk (DVD), and a USB in an installable-format or executable-format file. The programs may also be provided or distributed via the network such as the Internet. The various programs may also be provided by being incorporated in advance in a non-volatile storage medium such as a ROM. 
     The programs executed by the information processing apparatus in each of the embodiments above are configured as module which includes the above-mentioned each unit. As the actual hardware, a CPU (processor) reads and executes the program from the storage medium, whereby each unit is loaded on the main storage device and formed in the main storage device. 
     In the above embodiments, the image forming apparatus of the present invention has been described using an example applied to a multifunction peripheral having at least two functions of the copy function, the printer function, the scanner function, and the facsimile function. However, it may be applied to any image forming apparatus such as a copy machine, a printer, a scanner, and a facsimile machine. 
     An embodiment provides the effects in which the user can perform the ordering procedures for consumables even when the network is disconnected. 
     Although the invention has been described with respect to specific embodiments for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
