  The RAM 33 is used as a work area from which various control programs are read, or as a storage area for temporarily storing data. The CPU 31 controls each component of the multi-function device 1 while storing the processing result in the RAM 33 or the nonvolatile storage unit 34 according to the control program read from the ROM 32. In particular, the RAM 33 stores a screen display flag 67 which will be described in detail later. The RAM 33 stores a status parameter for storing which of the above-mentioned screens is currently displayed in the active state, and the CPU 31 refers to the status parameter so that the current operation panel 40 is stored. It is possible to determine which screen is displayed in an active state.

  The image reading unit 6 is controlled by the CPU 31 to read an image of a document placed on the document placement unit 3. Then, read data corresponding to the read image is generated.

  The printing unit 10 performs printing on the paper S fed from the paper feed tray 51 by the CPU 31 controlling the process unit 5, the conveyance belt 7, the fixing unit 8, and the like.

  The operation panel 40 is controlled by the CPU 31 to display the operation status and the like on the display 41 shown in FIG. In addition, a signal corresponding to an input operation by the user pressing the button group 42 is transmitted to the CPU 31. The CPU 31 accepts the transmitted signal as an operation instruction for the screen being displayed on the display 41 in an active state.

  The network I / F 37 and the USB I / F 38 are connected to an external computer (not shown), a medium (not shown), etc. via a communication line or a USB cable, and are capable of mutual data communication. It receives a print instruction for causing the printing unit 10 to perform printing, receives image data to be printed, and the like. An interface other than the network I / F 37 and the USB I / F 38 may be provided. For example, an interface corresponding to an SD card or the like may be provided.

  The detection unit 60 includes an insertion / extraction sensor 61 and a document detection sensor 69.

The insertion / extraction sensor 61 emits light toward the paper feed tray 51 and transmits two kinds of signals to the CPU 31 according to the strength of the reflected light that changes according to the distance in the front-rear direction from the paper feed tray 51 with respect to a certain threshold value. To do. In particular, two types of signals are transmitted to the CPU 31 depending on whether the paper feed tray 51 is in the ejected state or the inserted state. The extracted state is a state where a part or all of the paper feed tray 51 is extracted from the apparatus main body 2, and the reflected light becomes weaker than a certain threshold value. On the other hand, the insertion state is a state in which all the components are inserted into the apparatus main body 2 and are accommodated in the apparatus main body 2, and the reflected light is assumed to be stronger than a certain threshold value.
The insertion / extraction sensor 61 is not limited to the above-described configuration, and any configuration that transmits different signals according to the insertion / extraction of the paper feed tray 51 may be used.

  The document detection sensor 69 emits light toward a transparent member on which the document is placed on the document placement unit 3, and two types are determined depending on the presence of the document on the document placement unit 3 according to the brightness of the reflected light. The signal is transmitted to the CPU 31.

  The motor 23 is controlled by the CPU 31 to transmit power to the belt mechanism 25.

  Hereinafter, the screen display flag 67 will be described in more detail.

  The screen display flag 67 is used to distinguish whether or not the paper setting screen 45 needs to be displayed.

  In this embodiment, the CPU 31 stores “1” in the screen display flag 67 when the signal of the insertion / extraction sensor 61 changes from the insertion state to the extraction state. That is, when it is necessary to display the paper setting screen 45, “1” is stored in the screen display flag 67. If it is not necessary to display the paper setting screen 45 such as when the paper setting screen 45 is displayed after storing “1” in the screen display flag 67, “0” is stored in the screen display flag 67. To do.

  The screen display flag 67 is used when the CPU 31 determines whether or not the paper setting screen 45 needs to be displayed in the setting screen display processing described in detail later.

  Note that a configuration in which “1” is stored in the screen display flag 67 when the signal of the insertion / extraction sensor 61 changes from the extraction state to the insertion state may be employed. That is, the case where the CPU 31 stores “1” in the screen display flag 67 may be anything as long as it is detected that there is a possibility that the type of the paper S is changed in the paper feed tray 51. The sensor may not be the insertion / extraction sensor 61. Any sensor may be used as long as it detects that the type of the paper S in the paper feed tray 51 may have been changed.

  As described above, the process of detecting a change in the insertion / extraction state of the paper feed tray 51 based on the signal output from the insertion / extraction sensor 61 is an example of the detection process.

  Hereinafter, a setting screen display process related to a setting screen display function for controlling the display of the paper setting screen 45 on the operation panel 40 of the multifunction device 1 will be described with reference to FIG.

  FIG. 10 is a flowchart of a setting screen display process performed by the multifunction device 1.

  The setting screen display process is executed by the CPU 31 when the multifunction device 1 is powered on.

  When the setting screen display process is started, first, the CPU 31 stores “0” in the screen display flag 67 to initialize the flag when the MFP 1 is turned on (S95).

  Then, the CPU 31 should display the paper setting screen 45 </ b> A by determining whether or not “1” is stored in the screen display flag 67 so that the paper feed tray 51 is changed to the extraction state. It is determined whether or not there is (S100). By determining that “1” is stored in the screen display flag 67A, until it is determined that the paper setting screen 45 should be displayed when the paper feed tray 51 is changed to the ejected state (S100). : NO), the process of S100 is repeated.

  When “1” is stored in the screen display flag 67 and it is determined that the paper setting screen 45 should be displayed because the paper feed tray 51 has changed to the ejected state (S100: YES), The CPU 31 determines whether one of the reading screen 90b, the copying screen 92b, and the printing screen 94b is being displayed in an active state, whereby the printing unit 10 or the image reading unit 6 operates. It is determined whether it is in the middle (S105).

  By determining that any one of the reading screen 90b, the copying screen 92b, and the printing screen 94b is being displayed in an active state, it is determined that the printing unit 10 or the image reading unit 6 is operating. In this case (S105: YES), the CPU 31 determines whether or not the display of any one of the reading screen 90b, the copying screen 92b, and the printing screen 94b is finished and the main menu screen 89 is displayed. Is determined to determine whether the operations of the printing unit 10 and the image reading unit 6 have been completed (S110). The printing unit 10 or the image reading unit is determined by determining that the main menu screen 89 is displayed after the display of any one of the reading screen 90b, the copying screen 92b, and the printing screen 94b is being displayed. Until it is determined that the operation No. 6 is completed (S110: NO), the determination of S110 is performed.

  The printing unit 10 or the image reading unit is determined by determining that the main menu screen 89 is displayed after the display of any one of the reading screen 90b, the copying screen 92b, and the printing screen 94b is being displayed. 6 is completed (S110: YES), the CPU 31 starts to display the active state of the paper setting screen 45 corresponding to the paper feed tray 51A on the operation panel 40 (S115). Then, the value of the screen display flag 67 is changed to “0”, and the process proceeds to S100. Note that the paper setting screen 45 started to be displayed in S115 is erased from the display 41 by operating the setting button 45i or the erasing button 45j by the user pressing the button group 42 as described above.

  On the other hand, when it is determined that the printing unit 10 and the image reading unit 6 are not operating by determining that all of the reading screen 90b, the copying screen 92b, and the printing screen 94b are in an active state and are not being displayed ( (S105: NO), the CPU 31 determines whether the main menu screen 89 is being displayed in an active state, thereby determining whether the apparatus is on standby for use (S120).

If the CPU 31 determines that the main menu screen 89 is being displayed in the active state and is waiting to start using the apparatus (S120: YES), the CPU 31 sets the paper setting screen corresponding to the paper feed tray 51. The display on the operation panel 40 of 45 is started (S115). Then, the value of the screen display flag 67 is changed to “0”, and the process proceeds to S100.
When determining that the main menu screen 89 is not being displayed in the active state, the CPU 31 changes the value of the screen display flag 67 to “0” when determining that the use of the apparatus is not waiting (S120: NO). Then, the process proceeds to S100.

  When the CPU 31 determines that the paper setting screen 45 should be displayed because the paper feed tray 51 has changed to the ejected state (S100: YES), one of printing, copying, and reading is being executed. If it is determined that the operation control screen is in an active state (S105: YES), the paper setting screen 45 is displayed until it is determined that any of the printing, copying, and reading operations being executed has been completed. Not performed (S110, S115). On the other hand, when it is determined that any one of printing, copying, and reading is not being executed and it is determined that the screen waiting for the apparatus to be used is in an active state (S105: NO, S120: YES), the CPU 31 Then, display of the paper setting screen 45 corresponding to the paper feed tray 51 on the operation panel 40 is started (S115). In this way, during operations such as printing, copying, and reading, by controlling not to display the paper setting screen 45, operations such as printing, copying, and reading are controlled, and in particular, an instruction to cancel is not hindered. That is, a series of processes that are not restricted is an example of a change restriction process.

  If the MFP 1 has a facsimile function for transmitting image data of a document read to the outside, whether or not the screen in the active state in which the user can instruct to stop fax transmission is being displayed in the process of S105. If the screen in the active state that can be instructed to stop fax transmission is being displayed, the paper setting screen 45 may be displayed after the display is completed.

  Note that a method for determining whether or not the operation of the printing unit 10 or the image reading unit 6 has ended in S110, that is, whether or not the period during which the paper setting screen 45 is not displayed has been determined is that the displayed screen is It is not restricted to the method of judging by having changed to the main menu screen 89. For example, the RAM 33 has a status parameter for storing the current operation state of the multifunction device 1, and the operation state of the multifunction device 1 is determined to be no longer during printing, reading, or copying. May be.

<Effect>
According to the present embodiment, during the execution of copying, reading, printing, and the like by the printing unit 10 and the image reading unit 6, the paper setting screen 45 is displayed and the setting relating to the type of the paper S that is newly replenished to the paper feed tray 51. By the process of accepting, the acceptance of an instruction to control execution of copying, reading, printing, etc., in particular, an instruction to cancel is not limited. Therefore, it is possible to reduce the possibility that the user's operation for giving an instruction to control execution of copying, reading, printing, and the like will be hindered. Therefore, it is possible to reduce the possibility of preventing proper execution or cancellation of copying, reading, printing, and the like.

  In addition, during the execution of copying, reading, printing, and the like by the printing unit 10 and the image reading unit 6, a process for accepting settings relating to the type of the paper S that is newly supplied to the paper feed tray 51 without displaying the paper setting screen 45. By not performing, the acceptance of instructions for controlling execution of copying, reading, printing, etc. can be restricted.

  In addition, it is possible to reduce the possibility of preventing appropriate execution of copying, reading, printing, and the like, and it is possible to prompt the user to make settings regarding the type of paper S that is newly supplied to the paper feed tray 51.

(Second embodiment)
Next, a second embodiment will be described with reference to FIG. The points not described are the same as in the first embodiment.

  FIG. 11 is a schematic diagram showing the next original confirmation screen 96.

  In the second embodiment, the multifunction device 1 displays a next document confirmation screen 96 instead of displaying the reading screen 90b after reading the document placed on the document placement unit 3 in the reading function.

  On the next document confirmation screen 96, there is information prompting the user to confirm whether or not there is a document (an example of the second document) to be read next to the document (an example of the first document) that was read immediately before. It is displayed.

  While the next original confirmation screen 96 is being displayed in the active state, the multi function device 1 indicates that there is an original to be read next to the original that has been read immediately before and has been replaced, or there is no original to be read next. Any instruction can be accepted through the operation of the numeric keypad of the user's button group 42.

  When the next original confirmation screen 96 is being displayed, if there is an original to be read next to the original that was read immediately before and an instruction is received from the user through the operation of the numeric keypad of the button group 42, the multifunction device 1 Instead of the next original confirmation screen 96, the reading screen 90b is displayed on the display 41 again. Then, reading of the original that has been exchanged and is newly placed on the original placing portion 3 is started.

  On the other hand, when the next original confirmation screen 96 is being displayed in the active state, if there is no original to be read next to the original that was read immediately before, an instruction is received from the user through the operation of the numeric keypad of the button group 42. 1 stores the image read so far in a predetermined memory or the like, displays the main menu screen 89 instead of the next original confirmation screen 96, and ends the reading function.

  When the next original confirmation screen 96 is being displayed in the active state and the instruction is not accepted for a certain period of time, the multi-function device 1 deletes the display of the next original confirmation screen 96 and the images read up to that point are predetermined. The main menu screen 89 is displayed in place of the next original confirmation screen 96, and the reading function is terminated.

  The above applies not only to the reading function but also to the copying function in which reading is performed. That is, after reading the original placed on the original placement portion 3, a next original confirmation screen 96 is displayed instead of the display of the copying screen 92b. In the second embodiment, when the reading setting screen 90a or the copy setting screen 92a is being displayed in the active state, both sides are set by the setting item of the reading surface, and when the copy setting screen 92a is being displayed. In the reading operation in the case where the printing operation for assigning a plurality of original images to one sheet S is set in the setting item, the next original confirmation screen 96 is displayed after reading the original placed on the original placement portion 3. It shall be. The case where the next original confirmation screen 96 is displayed is not limited to the above example, and may be anything as long as there is a possibility of reading a plurality of originals.

  When the MFP 1 has a document to be read next to the document read immediately before and receives an instruction from the user through the operation of the operation panel 40 that the document has been replaced, the newly placed document is read. .

  Based on the above configuration, in the second embodiment, the processes in S105 and S110 are different from those in the first embodiment.

  In the second embodiment, assuming that “1” is stored in the screen display flag 67, it is determined that the paper setting screen 45 should be displayed when the paper feed tray 51 is changed to the ejected state. In this case (S100: YES), the CPU 31 determines whether or not the next original confirmation screen 96 is being displayed in the active state, thereby confirming the replacement state of the original to be read next and reading again. It is determined whether the reading function or the copying function to be performed is in operation (S105).

  By determining that the next original confirmation screen 96 is being displayed in the active state, it is determined that the reading function or the copy function for confirming the replacement state of the next original to be read by the user and performing the reading again is operating. If so (S105: YES), the CPU 31 determines whether or not the operation of the printing unit 10 or the image reading unit 6 is finished by determining whether or not the reading function or the copying function is finished and the main menu screen 89 is displayed. It is determined whether or not (S110). By determining that the main menu screen 89 is displayed, the determination of S110 is performed until it is determined that the operations of the printing unit 10 and the image reading unit 6 have been completed (S110: NO).

  When the CPU 31 determines that the paper setting screen 45 should be displayed because the paper feed tray 51 has changed to the extracted state (S100: YES), the CPU 31 confirms with the user whether there is a document to be read next. If it is determined that the screen for confirming the next document to be read is in an active state (S105: YES), when reading or copying to be performed again is being executed and the user confirms whether there is a document to be read next. The paper setting screen 45 is not displayed until the user confirms the presence or absence and the execution of reading or copying is completed again (S110, S115). On the other hand, when it is determined that the screen for confirming with the user whether or not there is a document to be read next is not displayed in an active state, and when it is determined that a screen waiting for use of the apparatus is in an active state (S105: NO) , S120: YES), the CPU 31 starts displaying the operation panel 40 on the paper setting screen 45 corresponding to the paper feed tray 51 (S115). As described above, when the screen for confirming the user whether or not there is a document to be read next is in an active state, the display of the paper setting screen 45 is not displayed, and the instruction to set the type of the paper S is not accepted. A series of processes that do not hinder, that is, do not limit, the instruction for the presence or absence of a document to be read is an example of a change limiting process.

<Effect>
According to the present invention, the sheet setting screen 45 is displayed and a sheet to be newly replenished to the sheet feeding tray 51 during execution of reading or copying in which processing for accepting an instruction indicating whether or not there is a document to be read next is received from the user. The process of accepting the setting relating to the type of S does not restrict the acceptance of an instruction indicating whether or not there is a document to be read next. Therefore, in particular, it is possible to reduce the possibility of obstructing the user's operation of reading the original to be read next, that is, giving an instruction to continue reading. Therefore, it is possible to reduce the possibility of preventing proper continuation of copying, reading, and the like.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. The points not described are the same as in the first embodiment.

  FIG. 12 is a flowchart of setting screen display processing that is performed by the multifunction device 1 and that is different from the first embodiment.

  In the third embodiment, similar to S95, after initialization of the screen display flag 67 (S495), it is determined whether or not the paper setting screen 45 should be displayed, similar to S100 (S500). The processing after it is determined that the paper setting screen 45 should be displayed (S500: YES) is different from the first embodiment.

  In the third embodiment, when it is determined that the paper setting screen 45 should be displayed (S500: YES), the CPU 31 selects one of the reading setting screen 90a, the copy setting screen 92a, and the print setting screen 94a. By determining whether or not the screen is being displayed in an active state, it is determined whether or not the operation of the printing unit 10 or the image reading unit 6 is being set (S505).

  By determining that any one of the reading setting screen 90a, the copy setting screen 92a, and the print setting screen 94a is being displayed in an active state, the operation of the printing unit 10 and the image reading unit 6 is being set. (S505: YES), the CPU 31 does not display the paper setting screen 45, and changes the type of the paper S placed on the paper feed tray 51 to the previously set type (an example of the current setting). ) Is not changed (S510). That is, for example, when an A4 size paper S is placed and the paper feed tray 51A is pulled out, the newly placed paper S is assumed to be A4 size. Note that the process of S510 may be a process of making the type of the paper S placed on the paper feed tray 51A indefinite. In this case, for example, it is conceivable to provide a sensor or the like for detecting the paper size of the paper S in the transport path 11 and to set the paper type by feeding paper. Since the paper setting screen 45 is not displayed after the process of S510, the value of the screen display flag 67 is changed to “0”, and the process proceeds to S500. Note that not displaying the paper setting screen 45A is read as restricting or prohibiting display of the paper setting screen 45.

  On the other hand, when it is determined that the operation of the printing unit 10 or the image reading unit 6 is not being set by determining that all the reading setting screen 90a, copy setting screen 92a, and print setting screen 94a are not being displayed (S505). : NO), the CPU 31 determines whether or not any one of the reading screen 90b, the copying screen 92b, and the printing screen 94b is being displayed in the active state, as in S105. A process of determining whether the printing unit 10 or the image reading unit 6 is operating is performed (S515). Hereinafter, the processes of S515, S520, S525, and S530 are the same as the processes of S105, S110, S115, and S120, respectively. That is, when it is determined that the printing unit 10 or the image reading unit 6 is operating, the display of the paper setting screen 45 is waited until the operations of the printing unit 10 and the image reading unit 6 are completed. When the main menu screen 89 is being displayed in an active state, that is, when it is determined that the apparatus is in a standby state for starting use of the apparatus, a paper setting screen 45 is displayed. After the end of the process of S525 and in the case of S530: NO, the value of the screen display flag 67A is changed to “0” as in S115 and S120, and then the process proceeds to S500.

  When the MFP 1 has a facsimile function for transmitting image data of a document read to the outside, whether or not the screen in the active state in which the user can give an instruction to start fax transmission is being displayed in step S505. In such a case, it may be configured such that the paper setting screen 45 is not displayed when the screen in the active state in which an instruction to start fax transmission is being displayed is being displayed.

  If it is determined that the printing unit 10 or the image reading unit 6 is operating (S515: YES), the display of the paper setting screen 45 is waited until the operations of the printing unit 10 and the image reading unit 6 are completed. For example, as in S510, the display of the paper setting screen 45 is not performed, and the type of the paper S placed on the tray 51 is set to the previously set type (an example of the current setting). Processing may be performed assuming that there is no change.

  If it is determined that the operation of the printing unit 10 or the image reading unit 6 is being set (S505: YES), the paper setting screen 45 is not displayed, and the paper S placed on the tray 51 is not displayed. Instead of performing the process of not changing the type from the previously set type (an example of the current setting), for example, as in S520 and S525, until the operation setting is completed and the operation is further completed A process of waiting for the display of the paper setting screen 45 may be performed.

  When the CPU 31 determines that the paper setting screen 45 should be displayed because the paper feed tray 51A has changed to the ejected state (S500: YES), the CPU 31 is currently setting operations such as printing, copying, and reading. (S505: YES), the paper setting screen 45 is not displayed, and the type of the paper S placed on the paper feed tray 51A is not changed from the previously set type. (S510). If it is determined that printing, copying, reading, or the like is being performed (S515: YES), the paper setting screen 45 is displayed after the operation of the printing unit 10 or the reading unit 5 is completed (S520, S525). . If it is determined that the apparatus is in a standby state for starting use (S530; YES), the paper setting screen 45 is displayed (S525). In this way, during the operation of printing, copying, reading and the like and during the setting of the operation, the instruction to control the operation of printing, copying, reading, etc. and the instruction to set the operation by not displaying the paper setting screen 45 A series of processes that do not hinder, that is, do not restrict, is an example of a change restriction process.

<Effect>
According to the present invention, the paper setting screen 45 is displayed and the paper S newly replenished to the paper feed tray 51 is displayed even during the setting of the contents such as copying, reading, and printing by the printing unit 10 and the image reading unit 6. The process of accepting the setting related to the type does not limit the acceptance of the setting instruction for the contents such as copying, reading, and printing. Therefore, it is possible to reduce the possibility of obstructing a user's operation for giving an instruction to control the execution of copying, reading, printing, and the like by the printing unit 10 and the image reading unit 6 and a setting instruction for the content. Accordingly, it is possible to reduce the possibility of impeding execution including appropriate preparation such as copying, reading, and printing.

  Further, in the configuration in which the display of the paper setting screen 45 is not displayed after the period for limiting the display, the paper supply tray 51 is newly replenished while reducing the possibility of preventing proper execution of copying, reading, printing, and the like. Settings relating to the type of paper S can be made.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIG. The points not described are the same as in the third embodiment.

  FIG. 13 is a schematic diagram showing a preview screen 97.

  In the fourth embodiment, unlike the third embodiment, the flow when reading a document is read by performing a reading operation twice on a single document. More specifically, when reading a document in the fourth embodiment, the multifunction device 1 first displays the active screen such as the reading screen 90b and the copying screen 92b on the document placement unit 3 while displaying them in an active state. Pre-reading that is the first reading of the placed document is performed. Next, the display is switched to a preview screen 97 described later in detail, and an adjustment operation for the main reading, which is the second reading, is accepted by the user while being in an active state. Then, the original reading of the original is performed in consideration of the received adjustment contents while displaying the active screen such as the reading screen 90b and the copying screen 92b. Then, only the image read by the main reading is stored in a predetermined memory or the like.

  The preview screen 97 is a setting screen for reading conditions when the original that has been pre-read is read.

  The preview screen 97 is displayed in place of the reading screen 90b and the copying screen 92b after the pre-reading is completed.

  On the preview screen 97, an image read by pre-reading (an image related to an object on which a job is executed, an example of an image read once) is displayed. Also, setting items such as resolution adopted in the main reading are displayed. With such a configuration, the user can adjust settings such as resolution while referring to an image obtained as a result of pre-reading.

  While the preview screen 97 is being displayed in the active state, it is possible to accept the setting of each setting item at the time of actual reading by accepting the pressing of the button group 42 from the user.

  When the user presses down the start key of the button group 42 while the preview screen 97 is being displayed in the active state, the setting of each setting item at the time of the main reading is received as the display content of the preview screen 97 and received. The original scanning of the original is started with the set contents. Further, in place of the preview screen 97, a reading screen 90b, a copying screen 92b, and the like are displayed again.

  The fourth embodiment is different from the third embodiment in that the screen for determining whether or not it is being displayed in the active state in S505 is a preview screen 97.

  When it is determined that the paper setting screen 45 should be displayed (S500: YES), the CPU 31 determines whether or not the preview screen 97 is being displayed in the active state (S505).

  If it is determined that the preview screen 97 is being displayed in the active state (S505: YES), the type of the paper S placed on the paper feed tray 51 is changed from the previously set type as in S510. It shall not be changed.

  On the other hand, when determining that the preview screen 97 is not being displayed in the active state (S505: NO), the CPU 31 selects one of the reading screen 90b, the copying screen 92b, and the printing screen 94b as in S105. By determining whether or not one screen is being displayed in an active state, processing for determining whether or not the printing unit 10 or the image reading unit 6 is operating is performed (S515).

  When the CPU 31 determines that the paper setting screen 45 should be displayed because the paper feed tray 51 has changed to the extraction state (S500: YES), the reading conditions for the main reading such as the resolution are being set. Is determined (S505: YES), the paper setting screen 45 is not displayed (S510). If it is determined that printing, copying, reading, or the like is being executed (S515: YES), the paper setting screen 45 is displayed after the execution of printing, copying, reading, etc. is completed (S520, S525). If it is determined that the apparatus is in a standby state for starting use (S530; YES), the paper setting screen 45 is displayed (S525). In this way, during the setting for reading the original image again, by not displaying the paper setting screen 45, an instruction for controlling execution operations such as printing, copying, and reading and an instruction for setting the reading conditions for the main reading A series of processes that do not hinder, that is, do not restrict, is an example of a change restriction process.

<Effect>
Further, even during the setting of the conditions for performing the reading, the paper setting screen 45 is displayed and the setting relating to the type of the paper S to be newly replenished to the paper feed tray 51 is received. It does not restrict acceptance of setting instructions for conditions for reading. Therefore, it is possible to reduce the possibility of obstructing the user's operation for giving an instruction to control execution of copying, reading, and the like, and an instruction to set conditions for performing the reading. Therefore, it is possible to reduce the possibility of preventing proper execution of copying, reading, and the like of reading the document once and then reading it again.

(5th Example)
Next, a fifth embodiment will be described with reference to FIG. The points not described are the same as in the third embodiment.

  FIG. 14 is a schematic diagram showing an image selection screen 98.

  In the fifth embodiment, the multifunction device 1 is configured to execute a printing function and print an image in the connected medium when a medium is connected via the USB I / F 38.

  When a printing function is started by connecting a medium to the multifunction device 1 via the USB I / F 38, an image selection screen 98 is displayed in an active state.

  The image selection screen 98 displays a list of printable images in the medium.

  While the image selection screen 98 is being displayed in the active state, the multifunction device 1 can accept an operation for selecting an image to be printed by pressing the button group 42 of the user.

  While the image selection screen 98 is being displayed in the active state, the multifunction device 1 displays the printing screen 94b instead of the image selection screen 98 by accepting the user pressing the start key of the button group 42. Printing of the selected image on the paper S is started by the operation of the printing unit 10.

  The fifth embodiment is different from the third embodiment in that the screen for determining whether or not the display is being performed in S505 is an image selection screen 98.

  When it is determined that the paper setting screen 45 should be displayed (S500: YES), the CPU 31 determines whether the image selection screen 98 is being displayed in the active state (S505).

  If it is determined that the image selection screen 98 is being displayed in the active state (S505: YES), the type of the paper S supplied to the paper feed tray 51 is set to the previously set type as in S510. It shall be the same type.

  On the other hand, when determining that the image selection screen 98 is not being displayed in the active state (S505: NO), the CPU 31 selects any of the reading screen 90b, the copying screen 92b, and the printing screen 94b as in S105. By determining whether or not one screen is being displayed in an active state, processing for determining whether or not the printing unit 10 or the image reading unit 6 is operating is performed (S515).

  When the CPU 31 determines that the paper setting screen 45 should be displayed because the paper feed tray 51 has changed to the ejected state (S500: YES), the CPU 31 determines that an image to be printed is being selected. If so (S505: YES), the paper setting screen 45 is not displayed (S510). If it is determined that operations such as printing, copying, and reading are being executed (S515: YES), the paper setting screen 45 is displayed after the execution of operations such as printing, copying, and reading is completed (S520). , S525). If it is determined that the apparatus is in a standby state for starting use (S530; YES), the paper setting screen 45 is displayed (S525). Thus, by not displaying the paper setting screen 45 during the selection of the image to be printed, the instruction for controlling the execution of operations such as printing, copying, and reading and the instruction for selecting the image to be printed are not hindered. That is, a series of processes that are not restricted is an example of a change restriction process.

<Effect>
According to the present invention, even when an image to be printed on the paper S is selected, the paper setting screen 45 is displayed, and the print on the paper S is performed by the process of accepting the setting relating to the type of the paper S newly replenished to the paper feed tray 51. The reception of an instruction to select an image to be performed is not limited. Therefore, it is possible to reduce the possibility of obstructing the user's operation for giving an instruction to control execution of copying, reading, printing, and the like and an instruction to select an image to be printed on the paper S. Accordingly, it is possible to reduce the possibility of hindering proper execution of printing performed by receiving selection of an image.

(Other examples)
(1) In the above-described embodiment, the image processing apparatus is the multi-function apparatus 1, but is not limited thereto, and may be an apparatus including only the printing apparatus 110 such as an inkjet printer.

  (2) In the above-described embodiment, the processing is executed by one CPU 31. However, the configuration is such that processing is executed by a plurality of CPUs 31, only hardware circuits such as ASIC (Application Specific Integrated Circuit), or the CPU 31 and the hardware. A configuration in which processing is executed by a circuit may be used.

  (3) In the above embodiment, the insertion / extraction of the sheet S as an example of the member to be inserted / extracted is detected by a signal transmitted from the insertion / extraction sensor 61 to the CPU 31. And it is not restricted to the insertion / extraction sensor 61. For example, a toner cartridge that contains toner (an example of a recording material) for forming an image on the paper S is used as a member that is inserted into and removed from the apparatus main body 2, and is a container that accommodates the toner cartridge provided in the apparatus main body 2. A configuration may be adopted in which a change in the toner cartridge is detected by a signal transmitted to the CPU 31 using a sensor that detects opening and closing of the cover of the unit as a sensor. In this configuration, for example, it is determined that a change in the toner cartridge insertion / extraction state is detected because the user may be performing an operation related to the replacement of the toner cartridge due to the cover being open. . If the CPU 31 determines that a change in the toner cartridge insertion / removal state is detected, for example, a message “Did you replace the toner?” Is displayed as information, and either YES or NO is displayed from the user. A screen for accepting the selection instruction is displayed. In this way, during execution of copying, reading, printing, etc. by the printing unit 10 or the image reading unit 6, the printing screen 94b, the reading screen 90b, the copying screen 92b, etc. are displayed in an active state. Instead, the message “Did you replace the toner?” Is displayed in an active state, and the process of accepting a selection instruction of either YES or NO from the user is not performed. That is, reception of instructions for controlling execution of copying, reading, printing, etc. is not limited. Therefore, it is possible to reduce the possibility that the user's operation for giving an instruction to control execution of copying, reading, printing, and the like will be hindered. In an inkjet printer or the like, an ink cartridge may be used instead of the toner cartridge.

  (4) In the above embodiment, in the multifunction machine 1, the paper feed tray 51 can be inserted into and removed from the apparatus main body 2. However, the present invention is not limited to this. It may be an MP tray that is provided on the printer and can hold the paper S. The sheets S stacked on the MP tray 51 are fed into the apparatus main body 2 from the opening formed by the outer wall of the apparatus main body 2. A method for detecting whether or not the display of the paper setting screen 45 is necessary is, for example, that a sensor for detecting the presence or absence of paper, such as an actuator, is provided on the MP tray, and the paper S on the MP tray is changed from being absent to being present. A method of detecting the change in the number can be considered. Further, the paper feed tray 51 may be a manual feed tray that holds the paper S by feeding only the leading edge of the paper S against the roller. In the manual feed tray, for example, by providing a sensor for detecting the presence or absence of the paper S in the same manner as the MP tray in front of the roller, the paper setting screen 45 is displayed by detecting the change from the absence of the paper S to the presence. Detect whether it is necessary. A plurality of paper feed trays 51 may be provided. Further, the trays need not all be the same type.

  (5) In the above embodiment, the user's instruction is accepted by operating the button group 42, but this need not be the case. For example, when the display 41 functions as a touch panel, a configuration in which an instruction from a user is received by an operation of the display 41 as a touch panel may be used.

  (6) In the above embodiment, the display setting screen 45 is displayed in the active state, and the control not to display is performed as the control that does not hinder the operation on the other display screens. Also good. For example, the paper setting screen 45 may be displayed, but the display may be displayed on the back of the screen being displayed in the active state, that is, the control may be performed such that the paper setting screen 45 is displayed in an inactive state.

  (7) In the above-described embodiment, the case where the main menu screen 89 is being displayed in the active state has been described as the case where the paper setting screen 45 is displayed. For example, the clock only screen is being displayed in the active state. It may be in some cases. That is, anything may be used as long as the screen waiting for the start of use of the device is being displayed in the active state.

  (8) In the above embodiment, the active state is defined as the state displayed in the foreground in the configuration in which a plurality of screens are displayed in an overlapping manner, but this need not be the case. For example, in a configuration in which a plurality of screens are displayed in parallel, it may be defined as a state that is not grayed out.
