     DETAILED DESCRIPTION 
     Hereinafter, a description will be given of an electronic apparatus and an image forming apparatus according to an embodiment of the present disclosure with reference to the drawings.  FIG. 1  is a diagram showing an entire configuration of a remote operation system formed by including the image forming apparatus being as one embodiment of the electronic apparatus according to the present disclosure. A remote operation system  11  includes an image forming apparatus  1  and an operator terminal  2 . The image forming apparatus  1  is provided with a display  473  having a touch panel function and is, for example, a multi-functional peripheral equipped with a copy function, a printer function, a scanner function, and a facsimile function. Components of the image forming apparatus  1 , except an image forming device  12  and a fixing device  13  to be described later, form the electronic apparatus according to the present embodiment. 
     The operator terminal  2  is provided with a display  21  having a touch panel function and with a keyboard  22 . The operator terminal  2  is for example a personal computer. The operator terminal  2  is capable of performing operation support to the image forming apparatus  1  from a remote place via the network, and displays the operation screen displayed on the display  473  of the image forming apparatus  1  on the display  21 . 
       FIG. 2A  and  FIG. 2B  are diagrams each showing an example of a screen displayed on the display  473  of the image forming apparatus  1 . An operation screen SC 1  shown in  FIG. 2A  is a “home” screen, and buttons such as “copy”, “send”, and so on are formed. Pressing of the “copy” button displays an operation screen SC 2  shown in  FIG. 2B  on the display  473 . 
     The operation screen SC 2  is a “quick setup” screen within the “copy” screen. Within the “copy” screen, there are screens for “original/paper/finishing”, “layout/edit”, and so on, other than the “quick setup” screen, but the “quick setup” screen is set at the upmost level. When a user presses the “copy” button on the “home” screen, a touch panel provided on the display  473  ( FIG. 4 ) receives the pressing and an instruction receiver  101  ( FIG. 4 ) receives a display instruction of the “quick setup” screen associated with the pressing. In accordance with this instruction, the display controller  104  ( FIG. 4 ) causes the display  473  to display the “quick setup” screen. 
     On the operation screen SC 2 , which is the “quick setup” screen, six buttons respectively associated with six major functions are displayed: i.e., buttons marked with “paper selection”, “color selection”, “page collection”, “zoom”, “2-sided/separate”, and “staple/punch”. 
     On the operation screen SC 2 , for example, when the user presses down the button marked with “color selection”, the touch panel receives the pressing, and the instruction receiver  101  ( FIG. 4 ) receives a display instruction of a pop-up by which the color mode can be selected, the display instruction being associated with the pressing. In accordance with this instruction, the display controller  104  ( FIG. 4 ) causes the display  473  to display the pop-up. There are three setting items: that are, “automatic color” mode performing printing by identifying between a color document and a monochrome document, “full color” mode performing printing in full color, and “monochrome” mode performing printing in black and white. 
     On the operation screen SC 2 , for example, when the button marked with “zoom” is pressed, the touch panel receives the pressing and the instruction receiver  101  ( FIG. 4 ) receives a display instruction of a pop-up by which copy magnification (setting value) can be set, the display instruction being associated with the pressing. In accordance with this instruction, the display controller  104  ( FIG. 4 ) causes the display  473  to display the pop-up. There are, for example, “automatic”, “200%”, “141%”, “100%”, and “93%” for setting items. 
     On the operation screen SC 2 , for example, when the button marked with “original/paper/finishing” is pressed, the touch panel receives the pressing and the instruction receiver  101  ( FIG. 4 ) receives a display instruction of an operation screen for “original/paper/finishing”, the display instruction being associated with the pressing. In accordance with this instruction, the display controller  104  ( FIG. 4 ) causes the display  473  to display the operation screen. On the operation screen for “original/paper/finishing”, when the user presses a button marked with “layout/edit”, the touch panel receives the pressing and the instruction receiver  101  ( FIG. 4 ) receives a display instruction of the operation screen for “layout/edit”, the display instruction being associated with the pressing. In accordance with this instruction, the display controller  104  ( FIG. 4 ) causes the display  473  to display the operation screen. 
       FIG. 3A  is a diagram showing an example of a screen displayed on the display  21  of the operator terminal  2  by the control from the display controller  104  when remote operation is under execution. An operation screen RS 1  displayed on the display  21  includes an operation screen (here, it is shown as the operation screen SC 2  in  FIG. 2B ) displayed on the display  473  of the image forming apparatus  1  at the time of actual operation and also includes an input area A 1  for displaying a text (including not only characters but also figures) that the operator inputs using the keyboard  22 . The operator can input a supplementary explanation for the operation through operating the keyboard  22  to input characters and others in the input area A 1 .

The document reading device  5  optically reads an image of a document fed to the document reading device  5  by the document feeding device  6  or an image of a document placed on not-illustrated contact glass, and generates image data. The image data generated by the document reading device  5  is stored in a not-illustrated image memory or the like. 
     Description will be given for image forming operation performed by the image forming apparatus  1 . Based on, for example, the image data generated by the document reading operation, the image data stored in the image memory, and the image data received from a computer (an external device  20 ) connected via a network, the image forming device  12  forms a toner image on a recording sheet, being as a recording medium, fed from the paper feeding device  14 . The image forming device  12  includes an image forming unit for magenta, an image forming unit for cyan, an image forming unit for yellow, an image forming unit for black, an intermediate transfer belt (image carrier), and a secondary transfer roller, all of which are not illustrated. Each of these image forming units includes a photosensitive drum, a developing device, a charging device, an exposure device, and a primary transfer roller. 
     The HDD  111  is a large capacity storage device. The HDD  111  includes a support information storage  112  storing as the support information the operation procedure data that indicates a series of operations sent from the operator terminal  2  (see  FIG. 1 ). The support information storage  112  is, for example, formed of a partial region of the HDD  111 . The support information storage  112  may be provided in any of the image forming apparatus  1 , the operator terminal  2 , and a server on the network. If provided in the image forming apparatus  1 , the support information storage  112  is formed in the HDD  111  through installation of a control program to be described later. 
     The fixing device  13  applies heat and pressure on the recording sheet on which the toner image is formed by the image forming device  12 , to thereby fix the toner image onto the recording sheet. The recording sheet having gone through the fixing processing is outputted to a not-illustrated output tray. The paper feeding device  14  has paper feed cassettes. 
     The operation device  47  accepts instructions from an operator for various types of operation and processing executable by the image forming apparatus  1 , such as an instruction to execute the image forming operation. The operation device  47  includes the display device  473  that displays operation guidance and other types of information for the operator. 
     The display  473  is a display device provided with the touch panel at the front side of its screen. This configuration allows the operator to operate the image forming apparatus  1  by touching buttons and keys displayed on the screen of the display  473 . 
     The network interface device  91  is a communication interface having a communication module, such as a not-illustrated LAN chip. The network interface device  91  sends and receives various data to and from the external apparatus  20  (for example, the operator terminal  2  shown in  FIG. 1 ) on the LAN or the Internet. The network interface device  91  is one example of the communication device recited in What is claimed is. 
     The control device  10  is formed by including a processor, a random access memory (RAM), a read only memory (ROM), and a dedicated hardware circuit. The processor is, for example, a central processing unit (CPU), an application specific integrated circuit (ASIC), or a micro processing unit (MPU). The control device  10  includes a controller  100 , the instruction receiver  101 , a remote operation executor  102 , a support information manager  103 , the display controller  104 , and a determiner  105 . 
     When the above processor operates in accordance with the control program stored on the HDD  11  or others, the control device  10  acts as the controller  100 , the instruction receiver  101 , the remote operation executor  102 , the support information manager  103 , the display controller  104 , and the determiner  105 . Alternatively, each of the controller  100  and other aforesaid components may not be implemented by the operation in accordance with the control program by the control device  10 , but may be constituted by a hardware circuit. Hereinafter, the same applies to the other embodiments unless otherwise stated. 
     The controller  100  governs overall operation control of the image forming apparatus  1 . The controller  100  is connected to the document feeding device  6 , the document reading device  5 , the image forming device  12 , the HDD  111 , the fixing device  13 , the paper feeding device  14 , the operation device  47 , and the network interface device  91  and controls the operations of these components. For example, the controller  100  controls the image forming device  12  to form the image on the recording medium. 
     The instruction receiver  101  receives input of an instruction from the user through the operation device  47 . The instruction receiver  101  receives the instruction from the user performed on hard keys provided on the operation device  47 , and furthermore, receives, through the touch panel provided on the display  473 , the instruction associated with the instruction (touch operation) from the user performed on the operation screen displayed on the display  473 . 
     The remote operation executor  102  executes processing necessary for the remote operation that receives an operation support from the operator terminal  2  through the network interface device  91 . 
     In receiving screen data of the operation screen (for example, the operation screen RS 1  shown in  FIG. 3A ) for the operation support that is being sent form the operator terminal  2 , the remote operation executor  102  causes the display  473  to display, as a remote support screen, a screen (for example, the operation screen MS 1  shown in  FIG. 3B ) based on the received screen data. Thereby, the screen is shared with the operator terminal  2 . 
     Also, in receiving an operation command that is being sent form the operator terminal  2 , the remote operation executor  102  executes processing in accordance with the received operation command. Thereby, the remote operation on the image forming apparatus  1  can be performed from the operator terminal  2 . Here, instead of actually operating the image forming apparatus  1  based on the operation command from the operator terminal  2 , the remote operation executor  102  may be configured to give only an operation advice to the user, so that the actual operation is to be performed by the user. 
       FIG. 5A  to  FIG. 8B  are diagrams each showing an example of screen switching when the remote operation is under execution.  FIG. 5A ,  FIG. 6A ,  FIG. 7A , and  FIG. 8A  respectively show the operation screens displayed on the display  21  of the operator terminal  2 .  FIG. 5B ,  FIG. 6B ,  FIG. 7B , and  FIG. 8B  respectively show the operation screens displayed on the display  473  of the image forming apparatus  1 . Hereinafter, a case where the user requests the operator to explain “how to scale up A 4  to A 3  and copy” will be described as an example. 
     An operation screen RS 2  displayed on the display  21  of the operator terminal  2  shown in  FIG. 5A  includes the operation screen SC 1 , which is the “home” screen displayed on the display  473  of the image forming apparatus  1  at the time of actual operation, and the input area A 1  is displayed on the operation screen RS 2 . An operation screen MS 2  displayed on the display  473  of the image forming apparatus  1  shown in  FIG. 5B  includes, in a part thereof, the operation screen RS 2  displayed on the operator terminal  2 . If audio data indicating a supplementary explanation is being sent from the operator terminal  2  to the image forming apparatus  1 , the controller  100  may be configured to output the audio indicated by the audio data from a not-illustrated speaker. 
     On the operation screens RS 2  and MS 2 , it is explained that the “copy” button within the “home” screen should be pressed. At a time where the operation screen MS 2  is being displayed on the display  473  of the image forming apparatus  1 , the operation command of pressing down the “copy” button is sent from the operator terminal  2  to the image forming apparatus  1  by the instruction of the operator. 
     An operation screen RS 3  shown in  FIG. 6A  includes the operation screen SC 2  that is displayed when the “copy” button is pressed on the “home” screen. The operation screen SC 2  is the “quick setup” screen within the “copy” screen. An operation screen MS 3  shown in  FIG. 6B  includes the operation screen RS 3  displayed on the operator terminal  2 . 
     On the operation screens RS 3  and MS 3 , it is explained that the “zoom” button within the “copy” screen should be pressed. At a time where the operation screen MS 3  is being displayed on the display  473 , the operation command of pressing down the “zoom” button is sent from the operator terminal  2  to the image forming apparatus  1  by the instruction of the operator. 
     An operation screen RS 4  shown in  FIG. 7A  includes a pop-up PU 1 : when the user presses the “zoom” button on the “copy” screen on the display screen of the display  473  of the image forming apparatus  1 , in accordance with the instruction corresponding to the pressing, the display controller  104  causes the display  473  to display the pop-up PU 1  on the operation screen SC 2 . An operation screen MS 4  shown in  FIG. 7B  is a display screen to be displayed on the display  473  of the image forming apparatus  1  and includes the operation screen RS 4  to be displayed on the operator terminal  2 . 
     On the operation screens RS 4  and MS 4 , it is explained that the “141% (A 4 &gt;&gt;A 3 , B 5 &gt;&gt;B 4 )” button on the pop-up PU 1  should be pressed. At a time where the operation screen MS 4  is being displayed on the display  473 , the operation command of pressing down the “141%” button is sent from the operator terminal  2  to the image forming apparatus  1  by the instruction of the operator. 
     The pop-up PU 1  closes as the “141%” button on the pop-up PU 1  is pressed down. Thus, an operation screen RS 5  shown in  FIG. 8A  does not include the pop-up PU 1 , but includes an image KS that represents the hard keys provided on the operation device  47  of the image forming apparatus  1 . Also, the lower low of the “zoom” button has been switched from displaying “100%” to “141%”. An operation screen MS 5  shown in  FIG. 8B  is a display screen to be displayed on the display  473  of the image forming apparatus  1  and includes the operation screen RS 5  displayed on the operator terminal  2 . 
     On the operation screens RS 5  and MS 5 , it is explained that a “start” button, one of the hard keys, should be pressed. At a time where the operation screen MS 5  is being displayed on the display  473 , the operation command of pressing down the “start” button is sent from the operator terminal  2  to the image forming apparatus  1  by the instruction of the operator. 
     The support information manager  103  associates the operation procedure data that is formed by including the series of the operation commands sent from the operator terminal  2  (i.e., the series of the operation inputted at the operator terminal  2 ) with the remote support screen, and furthermore, adds, to the operation procedure data, by each of the operation steps, information representing operation explanations and the supplementary explanations, and causes the support information storage  112  to store the operation procedure data as the support information. The support information manager  103  adds a title name and a support-information provider name to the support information and causes the support information storage  112  to store the support information. 
     For example, when the operation support is performed for “how to scale up A 4  to A 3  and copy”, the operation procedure data indicating the operation procedures detailed with reference to  FIG. 5A  to  FIG. 8B , that is, “1. copy button”, “2. zoom button”, “3. set 141%”, and “4. start button” is stored as the support information in the support information storage  112  by the support information manager  103 . 
     For example, the operator uses the keyboard  22  of the operator terminal  2  to input the title name (such as “how to scale up A 4  to A 3  and copy”) and the support-information provider name (such as “support center”), and the title name and the support-information provider name are sent from the operator terminal  2  to the image forming apparatus  1 . The support information manager  103  adds the title name and the support-information provider name to the support information, and stores the support information in the support information storage  112 . 
     Also, as the support information, together with the operation procedures, the support information manager  103  stores image data of the remote support screen, which is displayed on the display  473  in accordance with the series of operation (for example the operation screens MS 2  to MS 5  shown in  FIG. 5B ,  FIG. 6B ,  FIG. 7B , and  FIG. 8B ), in the support information storage  112  in association with the operation procedure data. 
     The support information manager  103  is preferably configured to also include the text data inputted as the supplementary explanation by use of the input area A 1  into the support information and store the support information in the support information storage  112 . Furthermore, if the audio data is inputted at the operator terminal  2  as the supplementary explanation and is sent to the image forming apparatus  1 , the support information manager  103  is preferably configured to also include the audio data into the support information and store the support information in the support information storage  112 . 
     The support information manager  103  reads out and obtains the support information from the support information storage  112 . For example, when the instruction receiver  101  receives the user instruction requesting the support information to be displayed, the support information manager  103  reads out the title name and the support-information provider name stored in association with each piece of the support information stored in the support information storage  112 , and causes the display  473  to display an operation screen MS 6  including a list L 1  as shown in  FIG. 9 . When the instruction receiver  101  receives from the user, through the operation device  47 , the instruction of selecting one piece of support information from the list L 1 , the support information manager  103  reads out and obtains the support information indicated by the received instruction from the support information storage  112 . 
     Based on the support information obtained by the support information manager  103 , the display controller  104  causes the display  473  to display the operation procedures indicated by the operation procedure data included in the support information, and also causes the display  473  to display a screen based on the image data included in the support information (operation screens MS 7  to MS 12  shown in  FIG. 10A  to  FIG. 12B , to be described later). 
       FIG. 10A  to  FIG. 12B  are diagrams each showing an example of the screen switching when the display controller  104  causes the display  473  to display the support information, and showing the operation screen displayed on the display  473  of the image forming apparatus  1 . Here, description will be given to the case where the support information whose title name is “how to scale up A 4  to A 3  and copy” is selected from the list L 1  by the user. 
     On an operation screen MS 7  displayed on the display  473  of the image forming apparatus  1  shown in  FIG. 10A , operation procedures OP 1  are displayed and a selection button B 1  marked with “next” and a selection button B 2  marked with “back” are displayed. When the instruction receiver  101  receives the instruction from the user on the selection button B 1  marked with “next”, the display controller  104  advances the screen displayed on the display  473  to the next page. When the instruction receiver  101  receives the instruction from the user on the selection button B 2  marked with “back”, the display controller  104  returns the screen displayed on the display  473  to one previous page. 
     An operation screen MS 8  shown in  FIG. 10B  is the screen that is one page advanced from the operation screen MS 7 , and includes the operation screen SC 1  that is the “home” screen. Also, operation procedures OP 2  are displayed on the operation screen MS 8 . Furthermore, the display controller  104  is preferably configured so as that the operation that should be performed on this screen (i.e., “1. copy button”) can be distinguished from other operations by, for example, changing the display size or changing the concentration. In this embodiment, changing the display size is adopted. 
     In another embodiment, as shown in  FIG. 13A , the display controller  104  may be configured to indicate to the user a position of the button that should be operated by displaying an arrow AR or the like. In still another embodiment, the display controller  104  may be configured to display a supplementary explanation El based on the text data inputted by the operator at the operator terminal  2  as shown in  FIG. 13B , or the controller  100  may be configured to cause the not-illustrated speaker to provide voice guide based on the audio data inputted by the operator at the operator terminal  2 . 
     An operation screen MS 9  shown in  FIG. 11A  is the screen that is one page advanced from the operation screen MS 8 , and includes the operation screen SC 2  that is the “copy” screen (“quick setup” screen). Also, the operation procedures OP 2  are displayed on the operation screen MS 9 . Furthermore, operations other than the operation that should be performed on this screen (i.e., operation on “2. zoom button”) are displayed in a small size. 
     An operation screen MS 10  shown in  FIG. 11B  is the screen that is one page advanced from the operation screen MS 9 , and includes the pop-up PU 1  to be displayed on the most front surface of the “copy” screen. Also, the operation procedures OP 2  are displayed on the operation screen MS 10 . Furthermore, operations other than the operation that should be performed on this screen (i.e., operation on “3. set 141%”) are displayed in a small size. 
     An operation screen MS 11  shown in  FIG. 12A  is the screen that is one page advanced from the operation screen MS 10 , and includes the image KS that represents the hard keys provided on the operation device  47  of the image forming apparatus  1 . Also, the operation procedures OP 2  are displayed on the operation screen MS 11 . Furthermore, operations other than the operation that should be performed on this screen (i.e., operation on “4. start button”) are displayed in a small size. 
     An operation screen MS 12  shown in  FIG. 12B  is the screen that is one page advanced from the operation screen MS 11 , and is the screen asking the user whether or not to receive the operation support to the operations indicated by the operation procedures OP 1  and OP 2  displayed on the display  473 . On the operation screen MS 12 , a message M 1  for asking the user whether or not to set the support mode that supports the operation is displayed, and in addition, a selection button B 3  marked with “YES” and a selection button B 4  marked with “NO” are displayed. Here, not related to the remotely performed control by the operator terminal  2  and the display of the operation screen MS 11  and the like, the display controller  104  may be configured to cause, after the support information is stored in the support information storage  112 , the display  473  to display the operation screen MS 12  in accordance with the instruction received by the instruction receiver  101  based on the operation of the operation device  47  by the user. In this case, a series of processing based on the support mode to be descried hereunder is executed without relating to the remotely performed control by the operator terminal  2  and the display of the operation screen MS 11  and the like. 
     When the pressing by the user on the selection button B 3  marked with “YES” is received by the touch panel and the instruction receiver  101  receives a setting instruction for the support mode associated with the pressing, the controller  100  sets the support mode. When the pressing by the user on the selection button B 4  marked with “NO” is received by the touch panel and the instruction receiver  101  receives a non-setting instruction for the support mode associated with the pressing, the controller  100  does not set the support mode. 
     When the support mode is set, based on the operation procedure data included in the support information obtained by the support information manager  103 , the determiner  105  collates the operation procedure indicated by the operation procedure data with the instruction from the user received by the instruction receiver  101 , and determines whether the instruction from the user coincides with the operation procedure. 
     When the determiner  105  determines that the instruction from the user does not coincide with the operation procedure, the display controller  104  causes the display  473  to display a message reporting that the instruction from the user is deviated from the operation procedure. 
     Hereinafter, description will be given to an example of the processing performed by the control device  10  of the image forming apparatus  1  with reference to a flowchart shown in  FIG. 14 . This processing is performed when the instruction receiver  101  receives the user instruction of setting the support mode. 
     Under a state where the support mode is being set by the controller  100  (S 1 ), when the instruction receiver  101  receives the instruction from the user (S 2 ), the determiner  105  collates the instruction from the user received by the instruction receiver  101  with the operation procedure indicated by the operation procedure data included in the support information obtained by the support information manager  103 , and determines whether the instruction from the user coincides with the operation procedure (S 3 ). 
     When the determiner  105  determines that the instruction from the user coincides with the operation procedure (YES at S 3 ), the controller  100  determines whether the operation is completed or not (S 4 ). 
     In determining that the operation is completed (YES at S 4 ), the controller  100  releases the support mode and returns to the normal mode (S 5 ). Then, the processing ends. 
     On the other hand, when the controller  100  determines that the operation is not completed (NO at S 4 ), the processing goes back to step S 2 . 
     At step S 3 , when the determiner  105  determines that the instruction from the user does not coincide with the operation procedure (the instruction from the user is deviated from the operation procedure) (NO at S 3 ), the display controller  104  controls the display  473  to display the message reporting that the instruction from the user is deviated from the operation procedure and also a message asking the user whether the deviation from the operation procedure is okay to be continued or not (S 6 ).  FIG. 15  is a diagram showing an example of the screen displayed on the display  473 . 
     On an operation screen MS 13  shown in  FIG. 15 , a message M 2  reporting that the instruction from the user is deviated from the operation procedure and a message M 3  asking the user whether the deviation from the operation procedure is okay to be continued or not are displayed, and also, a selection button B 5  marked with “YES” and a selection button B 6  marked with “NO” are displayed. 
     The controller  100  determines if the instruction receiver  101  has received a reply from the user of “it is okay that deviation continues” (S 7 ). In determining that the selection button B 5  marked with “YES” has been pressed down and the instruction receiver  101  has received the reply from the user of “it is okay that deviation continues” (YES at S 7 ), the controller  100  validates the instruction from the user deviated from the operation procedure (S 8 ), releases the support mode, and returns to the normal mode (S 5 ). Then, the processing ends. 
     On the other hand, in determining that the selection button B 6  marked with “NO” has been pressed down and the instruction receiver  101  has received through the operation device  47  the reply from the user of “it is not okay that deviation continues” (NO at S 7 ), the controller  100  invalidates the instruction from the user deviated from the operation procedure (S 9 ). Then, the processing goes back to step S 2 . 
     According to the above embodiment, since content of the support received in the past from the operator terminal  2  is stored as the support information, the user can check the same content of the support later on. For example, the content of the support can also be used as an operation manual specific for the user by printing the content. 
     In addition, when the user performs the same operation on his/her own by following the operation procedures indicated by the content of the support, the message reporting the user that the instruction received from the user is deviated from the operation procedure, so that even if there is an operation error, the user can be aware of the operation error. This makes it possible for the user to surely reproduce the operation procedures. That is, the user can easily perform the same operation again by following the operation procedures indicated by the content of the support received in the past. 
     Even if the user can check later on the content of the operation (i.e., the content of the support received in the past) in the techniques described in the above BACKGROUND, the user may not always be able to precisely reproduce the operation procedures indicated by the content of the operations. 
     In contrast, the present embodiment is capable of allowing the user to easily perform the same operation again by following the operation procedures indicated by the content of the support received in the past. 
     In the above embodiment, when the instruction from the user is deviated from the operation procedure, the message reporting such situation to the user is displayed. As another embodiment, when the user performs the same operation on his/her own by following the operation procedures indicated by the content of the support, it may be configured that based on the operation procedure data included in the support information obtained by the support information manager  103 , the display controller  104  changes a display manner of the operation button that should be operated to be different from a display manner of other operation button, or the instruction receiver  101  does not receive operation on the operation button that should not be operated. 
     The disclosure may be modified in various manners, without limitation to the above embodiments. Although the MFP exemplifies the electronic apparatus according to the present disclosure in the foregoing embodiments, the disclosure is also applicable to, for example, different types of image forming apparatuses or electronic apparatuses having copy function, a printer function, and facsimile function. 
     The configurations and processing according to the foregoing embodiments described with reference to  FIG. 1  to  FIG. 15  are merely exemplary, and in no way intended to limit the disclosure to those configurations and arrangements. 
     While the present disclosure has been described in detail with reference to the embodiments thereof, it would be apparent to those skilled in the art the various changes and modifications may be made therein within the scope defined by the appended claims.
