Description

[Technical Field]

[0001] The present disclosure relates to an image processing apparatus including a flatbed reading unit and an automatic document feeder unit, and a control method thereof. [Background technology]

[0002] Some image processing devices have an image reading mechanism that includes an automatic document feeder (hereinafter referred to as "ADF") unit on top of a flatbed (hereinafter referred to as "FB") reading unit. The FB reading unit is a type of reading unit that fixes a document on a transparent document table, shines light on it from below, and reads the reflected light. The ADF (Automatic Document Feeder) unit is a unit that automatically feeds multiple documents one by one. Reading a document with an FB reading unit is called FB scanning, and reading a document using an ADF unit is also called ADF scanning.

[0003] Such image processing devices can scan and process a variety of documents. For example, the image processing device can perform a scanning operation by sequentially feeding multiple documents set together in the ADF unit. Furthermore, the image processing device can also perform a scanning operation by placing documents that cannot be fed by the ADF unit, such as book documents, on the FB document tray. Such image processing devices detect that a document is set in the ADF unit and switch between ADF scanning and FB scanning. For example, Patent Document 1 discloses that, when a scan start operation is performed, if a sensor located at the feed port of the ADF unit detects that a document is set, ADF scanning is performed, and if no detection is detected, FB scanning is performed.

[0009] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the present disclosure, and not all combinations of features described in the following embodiments are necessarily essential to the solutions of the present disclosure. Note that the same reference numerals are used to designate the same components.

[0010] <<First Embodiment>> In this embodiment, an example of an image processing apparatus will be described using a multifunction peripheral 300 that incorporates a printing mechanism and a reading mechanism in the same housing and supports multiple functions such as a copy function. The reading mechanism includes a flatbed (FB) reading unit and an automatic document feeder (ADF (Automatic Document Feeder)) unit. Below, an example will be described that realizes improved operability in an image processing apparatus that has an FB reading unit and an ADF unit.

[0011] FIG. 1 is a perspective view showing the external appearance of a multifunction peripheral 300, which is an image processing device. FIG. 1(a) is a view showing a state in which an ADF unit 360 is closed, and FIG. 1(b) is a view showing a state in which the ADF unit 360 is open. FIG. 2 is a cross-sectional view showing the configuration of a reading mechanism 340. FIG. 2(a) is a cross-sectional view of the reading mechanism 340. FIG. 2(b) is an enlarged cross-sectional view of the reading mechanism 340. Both FIG. 2(a) and FIG. 2(b) are views showing a state in which the ADF unit 360 is closed, as in FIG. 1(a). The configuration of the multifunction peripheral 300 will be described below with reference to FIG. 1 and FIG. 2.

[0012] As shown in Figure 1, the upper side in the vertical direction is the +Z direction, the lower side is the -Z direction, the front side where the operation panel 303 is located is the -Y direction, the back side is the +Y direction, and in the width direction, the side where the document feed tray 361 is located is the +X direction, and the side where it is not located is the -X direction.

[0013] The reading mechanism 340 is disposed above the printing mechanism 330. An operation panel 303 is provided on the front of the multifunction device 300. The reading mechanism 340 has an FB reading unit 350 with a built-in sensor for image reading, and an ADF unit 360 that is provided above the FB reading unit 350 and can be opened and closed by a hinge part 369. The hinge part 369 is provided with an ADF open / close sensor that detects whether the ADF unit 360 is open or closed, and the multifunction device 300 can determine the open / close state of the ADF unit 360 based on the ADF open / close sensor.

[0014] The FB reading unit 350 has a built-in CIS sensor unit 351 as a sensor for reading images. By moving the CIS sensor unit 351 in the X direction in each drawing, the multifunction device 300 can read the image of a document placed on the FB document glass 352 (hereinafter referred to as an FB document 355). In addition, an ADF reading glass 353 is provided on the same surface as the FB document glass 352. The multifunction device 300 can read an ADF document 370 using the CIS sensor unit 351 by operating the ADF unit 360 with the CIS sensor unit 351 positioned below the ADF reading glass 353.

[0015] An original document feed tray 361 for placing an ADF original document 370 to be read is provided on the upper surface of the ADF unit 360. When the ADF original document 370 is set on the original document feed tray 361, an original document presence / absence sensor flag 363 is pushed down in the -Z direction. The optical sensor 364 detects that the original document presence / absence sensor flag 363 has been pushed down in the -Z direction, and the multifunction device 300 can determine whether the ADF original document 370 is present.

[0016] When the multifunction device 300 drives the document feed roller 365, the topmost sheet of the ADF document 370 is picked up, and the picked-up ADF document 370 is transported along a transport path 371 indicated by a dashed line. As the transported ADF document 370 passes over the ADF reading glass 353 of the FB reading unit 350, the front side is read by the CIS sensor unit 351. As the transport progresses further, the ADF document 370 is scooped up from the ADF reading glass 353 by the inclined portion 354 of the FB reading unit 350, and as the document passes over the back side reading CIS sensor 366, the back side is read. After the front and back sides have been read in this manner, the ADF document 370 is discharged by the document discharge roller 367 to a document discharge tray 368 of the ADF unit 360.

[0017] FIG. 2 illustrates the ADF unit 360 in a closed state. When the ADF unit 360 is open, the transport path 371 on the ADF unit 360 side separates from the ADF reading glass 353 on the FB reading unit 350 side, preventing ADF reading operations. Specifically, the CIS sensor unit 351 cannot read the ADF document 370 transported along the transport path 371. Furthermore, the inclined portion 354, located downstream of the ADF reading glass 353 in the transport direction, cannot pick up the ADF document 370 and transport it along the transport path 371. Therefore, if an ADF reading operation is attempted with the ADF unit 360 open, the multifunction peripheral 300 must immediately stop the transport operation and report an ADF document jam error. In this case, the user must manually remove the ADF document 370 remaining in the transport path, or the ADF document 370 itself may be damaged or soiled. As a result, user convenience is reduced.

[0018] 3 is a block diagram showing the configuration of the control system of the multifunction peripheral 300. The multifunction peripheral 300 is equipped with various units, including a main board 310 that controls the entire device, an operation panel 303 provided on the outside of the device, and a wireless LAN unit 304. A microprocessor-type CPU 311 disposed on the main board 310 operates according to a control program stored in a ROM-type program memory 313 connected via an internal bus 312, and the contents of a RAM-type data memory 314. The main board 310 also has a non-volatile memory 315 that can retain its contents even when power is cut off.

[0019] By writing various setting values ​​and data to non-volatile memory 315, CPU 311 can continue to operate based on the same setting values ​​and data when power is supplied again after being turned off. CPU 311 controls reading mechanism 340 via reading mechanism control circuit 317 to read an original document and store image data of the read original document in data memory 314. As will be described later, when controlling reading mechanism 340, CPU 311 appropriately controls ADF unit 360 and FB reading unit 350. This allows CPU 311 to selectively read an ADF original document 370 or an FB original document 355.

[0020] The CPU 311 also controls the print mechanism 330 via the print mechanism control circuit 316 to print on a recording medium an image represented by image data in the data memory 314. The CPU 311 performs wireless LAN communication with other devices by controlling the wireless LAN unit 304 via the wireless LAN communication control circuit 319. The CPU 311 controls the operation unit control circuit 318 to display the status of the multifunction peripheral 300 on the operation panel 303, display a function selection menu, and accept operations from the user.

[0021] FIG. 4 is a diagram showing the appearance of the operation panel 303. The operation panel 303 has indicator lamps using light-emitting diodes (LEDs), keys that accept operations, and a liquid crystal display with touch panel functionality. The power key 1002 is a key for turning the power of the multifunction peripheral 300 on and off. When the power key 1002 is pressed in the power-off state, the multifunction peripheral 300 transitions to the power-on state. When the power key 1002 is pressed in the power-on state, the multifunction peripheral 300 transitions to the power-off state. When the power key 1002 is pressed during an operation such as printing, the multifunction peripheral 300 transitions to the power-off state after completing or canceling the current operation. The power lamp 1001 is a lamp that indicates the power state of the multifunction peripheral 300. The power lamp 1001 is lit in the power-on state and is turned off in the power-off state. The power lamp 1001 may be configured to flash during operation, during power-on processing, and during power-off processing.

[0022] The liquid crystal touch panel 1008 is a liquid crystal display capable of displaying graphics. The liquid crystal touch panel 1008 doubles as a touch panel together with the liquid crystal display, and can accept touch operations from the user. The monochrome start key 1006 and the color start key 1005 are keys for accepting a command to start an operation of the multifunction peripheral 300, such as a copy function or a scan function, in a power-on standby state. When the monochrome start key 1006 is pressed, the multifunction peripheral 300 performs a monochrome copy operation. When the color start key 1005 is pressed, the multifunction peripheral 300 performs a color copy operation. The monochrome start key 1006 and the color start key 1005 are also used to execute other operations and processes depending on the device state of the multifunction peripheral 300 or the screen displayed on the liquid crystal touch panel 1008.

[0023] The stop key 1007 is a key for interrupting an ongoing operation or process and returning to a standby state. When the stop key 1007 is pressed in an error state, the multifunction device 300 can clear the error or cancel the job being executed. The error lamp 1009 is a lamp that indicates an error state of the multifunction device 300. The error lamp 1009 is off in a normal state and lights up or blinks when an error occurs. There are several types of errors, such as an out-of-ink error, an out-of-paper error, or a paper jam error. The blinking pattern of the error lamp 1009 can notify the user of the type of error. In addition, by controlling the display on the LCD touch panel 1008 in conjunction with the lighting or blinking of the error lamp 1009, the type of error and how to deal with it can be shown to the user.

[0024] 4, an example has been described in which the power key 1002 and other operation keys are configured as hardware keys fixedly provided on the operation panel 303, but not all of them need to be hardware keys. Buttons corresponding to these operation keys may be displayed on the liquid crystal touch panel 1008 and configured to accept touch operations.

[0025] Fig. 5 is a diagram showing an example of a display screen of operation panel 303. Fig. 5(a) to (g) respectively show display screens of operation panel 303. Each screen of Fig. 5(a) to (g) is displayed according to the state shown in the state transition diagram of Fig. 7 described later.

[0026] FIG. 5(a) shows an example of a home screen 1100. Mode selection buttons 1101 to 1103 for selecting an operation mode are displayed at the top of the home screen 1100. When a touch on each button is received, the display screen transitions to a standby screen for the operation mode. When a touch on the copy mode selection button 1101 is received, the display screen transitions to a standby screen for the copy mode. When a touch on the scan mode selection button 1102 is received, the display screen transitions to a standby screen for the scan mode. When a touch on the print mode selection button 1103 is received, the display screen transitions to a standby screen for the print mode.

[0027] Although an example in which three operation mode selection buttons are displayed is shown here, other operation modes may be present if the multifunction device 300 has many functions. For example, in addition to the illustrated buttons, selection buttons corresponding to operation modes such as a fax mode for sending and receiving facsimile data or a box mode for saving documents to the device's internal memory may be provided. Also, even for the same copy function, instead of a single operation mode button, an operation mode selection button may be provided for each type of copy, such as single-sided copying, double-sided copying, or layout copying. When there are so many operation modes that they cannot all fit on one screen, left and right page buttons 1104 and 1105 may be displayed, and buttons corresponding to other operation modes may be displayed by switching pages based on the touch of the page buttons 1104 and 1105.

[0028] Two function buttons are provided at the bottom of the home screen 1100. In this example screen, when the network button 1106 on the left is touched, the display screen transitions to a network setting screen, allowing for setting operations related to network connections. Furthermore, when the setup button 1107 on the right is touched, the display screen transitions to a setup screen, allowing for basic setup operations required for using the multifunction device 300.

[0029] FIG. 5B shows an example of a copy standby screen when there is no ADF document (referred to as an ADF document-free standby screen 1110). The ADF document-free standby screen 1110 is displayed when a touch is received on the copy mode selection button 1101 on the home screen 1100. "ADF document-free" indicates that no ADF document 370 is set in the document feed tray 361. A print setting display area 1112 in the upper left of the ADF document-free standby screen 1110 in FIG. 5B displays the size and type of print paper to be used when copying. A copy count display area 1113 in the upper right of the ADF document-free standby screen 1110 displays the number of copies to be printed. When a touch is received on the copy count display area 1113, the display screen transitions to a copy count setting screen, where the number of copies can be changed. An icon 1111 illustrating the print mode is displayed on the left side of the center of the ADF document-free standby screen 1110. Figure 5(b) shows an example of an icon for normal single-sided copying, but depending on the print settings, whether double-sided or single-sided printing is being performed, and the layout status of the original pages printed on one page are also displayed in a visible manner.

[0030] An ADF indicator 1116 is displayed on the right side of the center of the ADF no document standby screen 1110. Here, a grayed-out icon is displayed as an example of an indicator indicating that there is no document in the document feed tray 361 (i.e., "ADF no document"). The left function button of the ADF no document standby screen 1110 is a print settings button 1114, and when touched, the display screen transitions to a print settings screen for setting double-sided printing, document layout, etc. The right function button is a read settings button 1115, and when touched, the display screen transitions to a read settings screen for setting the read resolution, etc.

[0031] 5(c) shows an example of a copy standby screen when an ADF document is present (referred to as an ADF document-present standby screen 1120). "ADF document present" indicates that an ADF document 370 has been set in the document feed tray 361. The basic configuration of the ADF document-present standby screen 1120 is the same as the ADF document-free standby screen 1110 of FIG. 5(b). However, the difference is that the ADF document-present standby screen 1120 of FIG. 5(c) shows an ADF indicator 1126 displayed on the right side of the center of the screen, which indicates that a document is present in the document feed tray 361, as a highlighted icon.

[0032] FIG. 5(d) shows an example of a copy standby screen when there is an original in the ADF and the ADF is open (referred to as an ADF original present and ADF open standby screen 1130). "ADF open" indicates that the ADF unit 360 is open by the hinge 369, as shown in FIG. 1(b). The basic configuration of the ADF original present and ADF open standby screen 1130 is the same as the ADF no original standby screen 1110 shown in FIG. 5(b). However, the ADF original present and ADF open standby screen 1130 shown in FIG. 5(d) differs in that the ADF indicator 1136 displayed on the right side of the center of the screen indicates that there is an original in the document feed tray 361 but cannot be read. Specifically, the ADF indicator 1136 is an example of an icon displayed with a diagonal line overlaid. As explained above, when the ADF unit 360 is open, the transport path 371 on the ADF unit 360 side is separated from the ADF reading glass 353 on the FB reading unit 350 side, making it impossible to perform ADF reading operations. The ADF document present and ADF open standby screen 1130, which includes the ADF indicator 1136, is a screen for notifying the user that a document is present in the document feed tray 361 but cannot be read.

[0033] FIG. 5(e) shows an example of an ADF open error screen 1140. A title 1141 indicating the type of error is displayed at the top of the ADF open error screen 1140. A message 1142 explaining how to deal with the error is displayed below the title 1141. Specifically, a title indicating that the ADF unit 360 is open is displayed as the error type. Furthermore, the message 1142 advises users to press "Read with FB" or remove the ADF document when scanning with FB as a solution. The left function button is a FB scan button 1143. When the FB scan button 1143 is touched, the multifunction device 300 cancels the ADF open error state and starts a copy operation using FB scanning. That is, scanning with FB is performed while the ADF unit 360 is open. The right function button is a cancel button 1144. When the touch of the cancel button 1144 is accepted, the multifunction peripheral 300 cancels the ADF open error state, cancels the ADF copy operation that was being attempted to be executed, and returns to the standby screen.

[0034] 5(f) shows an example of an FB copy operation screen 1150. A title 1151 indicating that a copy operation is in progress is displayed at the top of the FB copy operation screen 1150. A message 1152 indicating that an FB document is being read is displayed below the title 1151.

[0035] 5(g) shows an example of an ADF copy operation screen 1160. A title 1161 indicating that a copy operation is in progress is displayed at the top of the ADF copy operation screen 1160. Below that, a message 1162 indicating that an ADF document is being read is displayed.

[0036] Fig. 6 is a flowchart showing the processing contents of the CPU 311 of the multifunction peripheral 300. The processing of the flowchart shown in Fig. 6 is executed by the CPU 311 of the multifunction peripheral 300 when the power of the multifunction peripheral 300 is turned on, and the processing from S2001 to S2010 is repeatedly executed while the power of the multifunction peripheral 300 is on. The flowchart of Fig. 6 is realized by the CPU 311 reading a program stored in the program memory 313 or the non-volatile memory 315, etc., into the data memory 314 and executing it. Note that some or all of the functions of the steps in Fig. 6 may be realized by hardware such as an ASIC or an electronic circuit. The symbol "S" in the explanation of each process indicates a step in the flowchart.

[0037] At the beginning of the repeat loop, in step S2002, the CPU 311 of the multifunction peripheral 300 waits for an event to occur. If an event is detected in step S2002, the CPU 311 proceeds to step S2003, where it branches to the required process depending on the type of the event that has occurred.

[0038] If the event detected in S2003 is a press of the power key on the operation panel 303, the CPU 311 proceeds to S2004 and transitions from the power-on state to the power-off state. Subsequently, in S2009, the CPU 311 transitions to an appropriate screen state. For example, the screen state may transition to a screen state indicating power-off. Then, in S2010, since the CPU 311 has transitioned to the power-off state, it exits the repeat loop and enters a sleep state until the next power-on.

[0039] If the event detected in S2003 is the reception of a job execution instruction, such as a print job or a read job, from an external device, the CPU 311 proceeds to S2005. In S2005, the CPU 311 executes an operation in accordance with the content of the received job. Then, in S2009, the CPU 311 transitions to an appropriate screen state. Then, the process returns to the beginning of the repeat loop, i.e., S2002.

[0040] If the event in S2003 is the pressing of start key 1005 or 1006 provided on operation panel 303, CPU 311 proceeds to S2006. In S2006, CPU 311 executes an operation according to the display screen state. For example, if the display screen is the ADF document-free standby screen 1110 and start key 1005 or 1006 is pressed, a copy operation of the FB document is executed in S2006. Also, for example, if the display screen is the ADF document-present standby screen 1120 and start key 1005 or 1006 is pressed, a copy operation of the ADF document is executed in S2006. Subsequently, in S2009, CPU 311 transitions to an appropriate screen state. Then, the process returns to the beginning of the repeat loop, i.e., S2002.

[0041] If the event detected in S2003 is an operation on the operation panel 303, the CPU 311 proceeds to S2007. In S2007, the CPU 311 executes processing according to the operation. For example, if the operation is on a touch panel, appropriate processing is executed according to the touched coordinates. If a touch on a button arranged on the screen is detected, the CPU 311 transitions to an appropriate screen or executes an operation according to the pressed button. Next, in S2009, the CPU 311 transitions to an appropriate screen state. Then, the process returns to the top of the repeat loop, i.e., S2002.

[0042] If the event detected in S2003 is another event, the CPU 311 proceeds to S2008. In S2008, the CPU 311 executes processing according to the event. Then, in S2009, the CPU 311 transitions to an appropriate screen state. Then, the process returns to the top of the repeat loop, i.e., S2002.

[0043] In this way, when the processing corresponding to the event that occurred is completed through the processing from S2003 to S2009, the process proceeds to S2009, and the CPU 311 determines the destination display screen based on the combination of the state and the event and makes the transition according to the state transition diagram of FIG. 7 described below.

[0044] Fig. 7 is a state transition diagram showing an example of state transitions of the multifunction device 300. Fig. 7 shows an excerpt of some of the states of the multifunction device 300 that are related to copy operations. "S" in the state transition diagram indicates a state (status) (the same applies throughout this specification).

[0045] The initial state in the state transition diagram in Figure 7 is a power-off state S3000. When a power-on operation is detected on the operation panel 303 of the multifunction peripheral 300 in the power-off state S3000, the multifunction peripheral 300 performs power-on processing and transitions to a power-on state S3001. Upon entering the power-on state S3001, the multifunction peripheral 300 first transitions to a home screen display state S3002. In the home screen display state S3002, the home screen 1100 is displayed.

[0046] When the copy mode selection button 1101 on the screen is touched in the home screen display state S3002, the multifunction peripheral 300 transitions to a copy standby state S3003. When the multifunction peripheral 300 enters the copy standby state S3003, it first enters an ADF no original state S3004, which displays the ADF no original standby screen 1110.

[0047] When it is detected that an original is present in the ADF in the no-original-in-the-ADF state S3004, the MFP 300 transitions to the no-original-in-the-ADF state S3005, which displays the ADF-present standby screen 1120. Here, the detection of the presence of an original in the ADF is performed using the optical sensor 364. Specifically, to detect the presence of an original in the ADF, the reading mechanism control circuit 317 monitors the optical sensor 364 and notifies the CPU 311 as an event that the output of the optical sensor 364 has changed from off to on using the document presence sensor flag 363. Conversely, the reading mechanism control circuit 317 notifies the CPU 311 as an event that the output of the optical sensor 364 has changed from on to off, thereby enabling the MFP 300 to detect the absence of an original in the ADF. When it is detected that an original is not present in the ADF in the document present state S3005, the MFP 300 transitions to the no-original-in-the-ADF state S3004.

[0048] When the ADF is detected to be open in the ADF document present state S3005, the MFP 300 transitions to the ADF document present and ADF open state S3006, which displays the ADF document present and ADF open standby screen 1130. Here, the ADF open, i.e., the ADF unit 360 being opened, can be detected using an open / close sensor (not shown) provided in the hinge portion 369. That is, the reading mechanism control circuit 317 monitors the open / close sensor provided in the hinge portion 369 and notifies the CPU 311 of an event that the output of the open / close sensor has changed from off to on. The reading mechanism control circuit 317 can also notify the CPU 311 of an event that the output of the open / close sensor has changed from on to off, which allows the MFP 300 to detect that the ADF is closed, i.e., that the ADF unit 360 has been closed. When the ADF is detected to be closed in the ADF document present and ADF open state S3006, the MFP 300 transitions to the ADF document present state S3005.

[0049] In the present embodiment, an example has been described in which the open / close state of the ADF unit 360 is detected by the open / close sensor of the hinge portion 369, but the open / close state of the ADF unit 360 may be detected by another method. For example, when the ADF unit 360 is opened or closed, the output value of the CIS sensor unit 351 for reading FB documents changes. For this reason, the multifunction peripheral 300 may be configured to detect the open / close state of the ADF unit 360 based on the output value of the CIS sensor unit 351.

[0050] When the start key 1005 or 1006 is pressed in the ADF document-not-present state S3004, the multifunction device 300 starts an FB document reading operation and transitions to an FB reading operation state S3007. When the start key 1005 or 1006 is pressed in the ADF document-present state S3005, the multifunction device 300 starts an ADF document reading operation and transitions to an ADF reading operation state S3008. When the start key 1005 or 1006 is pressed in the ADF document-present and ADF-open state S3006, the multifunction device 300 transitions to an ADF open error state S3009, in which an ADF open error screen 1140 is displayed. The ADF open error state S3009 is a state in which a reading operation instruction has been accepted by pressing the start key 1005 or 1006, but the reading operation is put on hold and the device is in standby.

[0051] When the cancel button 1144 is pressed in the ADF open error state S3009, the multifunction device 300 transitions to the ADF original present and ADF open state S3006, and displays the ADF original present and ADF open standby screen 1130. Also, when the read button 1143 is pressed in the FB or when no ADF original is detected in the ADF open error state S3009, the multifunction device 300 releases the hold on the read operation, starts the FB original reading operation, and transitions to the FB reading operation state S3007. That is, when the read button 1143 is pressed in the FB, the multifunction device 300 starts the FB original reading operation while the ADF unit 360 on which the ADF original is placed is open. Also, when the ADF unit 360 on which the ADF original is placed is open and the ADF original is removed, the FB original reading operation is performed while the ADF unit 360 is open. In this way, when the operation indicated by the ADF open error screen 1140 is performed, the multifunction device 300 releases the hold on the reading operation and performs the reading operation. In the FB reading operation state S3007, an FB copy operation in progress screen 1150 is displayed. Also, in the ADF open error state S3009, when it is detected that the ADF unit 360 has been closed, the multifunction device 300 starts the ADF document reading operation and transitions to the ADF reading operation state S3008. In the ADF reading operation state S3008, an ADF copy operation in progress screen 1160 is displayed.

[0052] With the above configuration, when the start keys 1005 and 1006 are pressed while there are documents in the document feed tray 361 and the ADF unit 360 is open, the user can be notified of how to deal with the error in an easy-to-understand manner. That is, when the start keys 1005 and 1006 are pressed while there are documents in the document feed tray 361 and the ADF unit 360 is open, the multifunction peripheral 300 transitions to an ADF open error state S3009, which displays an ADF open error screen 1140. The ADF open error screen 1140 notifies the user of how to deal with the error. In addition, multiple error solutions are notified.

[0053] For example, when scanning with FB, there may be cases where the user scans without closing the ADF unit 360. In this case, if the start keys 1005 and 1006 are pressed while a document is placed on the ADF unit 360, a typical multifunction device will wait for the ADF unit 360 to close in order to scan the document using the ADF unit 360. Then, once the ADF unit 360 is closed, scanning using the ADF unit 360 is performed. Alternatively, in a multifunction device that cannot detect whether the ADF unit 360 is open or closed, feeding using the ADF unit 360 may occur, resulting in a document jam error.

[0054] In this embodiment, the ADF open error screen 1140 notifies the user of how to deal with the error. Specifically, the user is notified of multiple ways to deal with the error in order to perform scanning using the FB. Therefore, even if there is a document in the document feed tray 361 and the ADF unit 360 is open, the user can perform scanning using the FB in accordance with the ways to deal with the error. Note that although it is assumed here that the user will perform scanning using the FB, it is also possible that the user may wish to perform scanning using the ADF unit 360. Therefore, the ADF open error screen 1140 may notify the user of how to deal with the error in order to perform scanning using the ADF.

[0055] Also, a cancel button 1144 is displayed as a solution on the ADF open error screen 1140. When the user presses the cancel button 1144, the multifunction device 300 can return to the state before the start keys 1005 and 1006 were pressed, that is, the ADF document present and ADF open standby screen 1130 in the case of the ADF document present and ADF open state S3006.

[0056] In this way, in this embodiment, if the start keys 1005 and 1006 are pressed while there is a document in the document feed tray 361 and the ADF unit 360 is open, the user can be notified of how to deal with the problem. Then, based on the operation by the user who has confirmed the notification on the ADF open error screen 1140, the user can select whether to read using the ADF or the FB, depending on their intention.

[0057] In this embodiment, ADF indicators 1116, 1126, and 1136 are displayed on the copy standby screen before the start keys 1005 and 1006 are pressed. For example, a user who sees the ADF indicator 1116 in FIG. 5B can recognize that there are no documents in the document feed tray 361. A user who sees the ADF indicator 1126 in FIG. 5C can recognize that there are documents in the document feed tray 361. A user who sees the ADF indicator 1136 in FIG. 5D can recognize that there are documents in the document feed tray 361 but that the ADF is unavailable, i.e., the ADF unit 360 is open. By using such ADF indicators, user operability can be further improved. For example, in the case of the ADF document presence and ADF open state S3006, the ADF indicator 1136 allows the user to recognize that the ADF cannot be executed. Pressing the start keys 1005 and 1006 in this state suggests that the user desires FB scanning. For this reason, the ADF open error screen 1140 notifies the user of several ways to deal with the problem in order to perform scanning with the FB.

[0058] Note that the description of the state transition diagram in FIG. 7 was based on an example in which the MFP 300 transitions to the ADF no-document state S3004 upon entering the copy standby state S3003. However, the MFP 300 transitions to a corresponding state depending on the state of the loaded document and the open or closed state of the ADF. For example, if the copy mode selection button 1101 is touched when a document is present in the ADF and the ADF is closed, the MFP 300 transitions to the copy standby state S3003 and transitions to the ADF document present state S3005. Similarly, if the copy mode selection button 1101 is touched when a document is present in the ADF and the ADF is open, the MFP 300 transitions to the copy standby state S3003 and transitions to the ADF document present and ADF open state S3006. In other words, when the copy mode selection button 1101 is touched, the MFP 300 can transition to the corresponding copy standby state without passing through the ADF no-document state S3004.

[0059] In addition, in the description of this embodiment, an example has been given in which the ADF open error screen 1140 is always displayed as the operation when the start key 1005 or 1006 is pressed in the ADF open state S3006 when a document is present in the ADF. However, this embodiment is not limited to this example. As a different example, the multifunction peripheral 300 may be configured to start a full-frame document reading operation when the start key 1005 or 1006 is pressed in the ADF open state S3006. As described above, the ADF indicator 1136 allows the user to confirm that the ADF cannot be executed, and therefore pressing the start key 1005 or 1006 in this state suggests that the user desires full-frame scanning. Alternatively, the user may be allowed to select whether to display an ADF open error or to perform full-frame document reading as an item in the reading settings.

[0060] As described above, according to this embodiment, it is possible to improve the operability of an image processing apparatus having the FB reading unit 350 and the ADF unit 360. For example, it is possible to improve the operability when a document is set in the ADF unit 360 but the document is to be read using the FB reading unit 350.

[0061] <<Second embodiment>> In the first embodiment, an example was described in which three states of the ADF indicator are displayed on the screen: no document in the ADF, a document in the ADF, and a document in the ADF and the ADF open. Examples of display modes for the ADF indicator, such as a grayed-out display, a highlighted display, and an icon with a diagonal line over it, were described. In this embodiment, other display modes for the ADF indicator will be described. The basic configuration and processing are the same as those described in the first embodiment, so a description will be omitted here and the differences will be mainly described.

[0062] 8A and 8B are diagrams showing examples of other display forms of the copy standby screens (standby screen 1110 when no document is in the ADF, standby screen 1120 when a document is in the ADF, and standby screen 1130 when a document is in the ADF and the ADF is open) described in the first embodiment.

[0063] FIG. 8(a) shows other examples of copy standby screens (standby screen 1110 when no document is in the ADF, standby screen 1120 when a document is present in the ADF, and standby screen 1130 when a document is present in the ADF and the ADF is open). In the standby screen 1110 when no document is in the ADF, the ADF indicator 1116 is not displayed. In the standby screen 1120 when a document is present in the ADF, a highlighted ADF indicator 1126 is displayed, as in the first embodiment. In the standby screen 1130 when a document is present in the ADF and the ADF is open, a shaded ADF indicator 1136 is displayed, as in the first embodiment. In this way, the presence or absence of an ADF document may be displayed so as to notify the user of the presence or absence of an ADF indicator.

[0064] FIG. 8B shows further examples of copy standby screens (a standby screen 1110 when no document is present in the ADF, a standby screen 1120 when a document is present in the ADF, and a standby screen 1130 when a document is present in the ADF and the ADF is open). The standby screen 1110 when no document is present in the ADF displays a grayed-out ADF indicator 1116, as in the first embodiment. The standby screen 1120 when a document is present in the ADF displays a highlighted ADF indicator 1126, as in the first embodiment. The standby screen 1130 when a document is present in the ADF and the ADF is open displays an ADF indicator 1136 highlighted in a different color. For example, the standby screen 1120 when a document is present in the ADF may display the ADF indicator in blue, and the standby screen 1130 when a document is present in the ADF and the ADF is open may display the ADF indicator in red. In this way, different colors may be used to indicate whether ADF reading is possible or not.

[0065] FIG. 8(c) shows further examples of copy standby screens (a standby screen 1110 when there is no document in the ADF, a standby screen 1120 when there is a document in the ADF, and a standby screen 1130 when there is a document in the ADF and the ADF is open). In the standby screen 1110 when there is no document in the ADF, a grayed-out ADF indicator 1116 is displayed, as in the first embodiment. In the standby screen 1120 when there is a document in the ADF, a highlighted ADF indicator 1126 is displayed, as in the first embodiment. In the standby screen 1130 when there is a document in the ADF and the ADF is open, an ADF indicator 1137 indicating that the ADF is open is displayed below the highlighted ADF indicator 1126. In this way, the presence or absence of a document in the ADF and the open ADF may be displayed as separate indicators.

[0066] FIG. 8(d) shows further examples of copy standby screens (a standby screen 1110 when there is no ADF document, a standby screen 1120 when there is an ADF document, and a standby screen 1130 when there is an ADF document and the ADF is open). In this example, the presence or absence of an ADF document, the open state of the ADF, and the like are displayed using images such as diagrams or photographs rather than icons or text. In the standby screen 1110 when there is no ADF document, an image showing the appearance of the document feed tray 361 when there is no ADF document 370 is displayed as an ADF indicator 1116. In the standby screen 1120 when there is an ADF document, an image showing the appearance of the document feed tray 361 when the ADF document 370 is set is displayed as an ADF indicator 1126. In the standby screen 1130 when there is an ADF document and the ADF is open, an image showing the appearance of the ADF unit 360 in an open state is displayed as an ADF indicator 1136 indicating that the ADF is open. In this way, the ADF indicator may be configured to be displayed in a form other than an icon or text.

[0067] Display modes other than those described above may also be used. Instead of displaying on the liquid crystal touch panel 1008, the operation panel 303 may be provided with an indicator lamp for display. For example, a lamp indicating that there is an original in the ADF and a lamp indicating that the ADF is open may be provided. Alternatively, one lamp may be configured to display different colors or patterns depending on whether there is an original in the ADF or whether there is an original in the ADF and the ADF is open.

[0068] <<Third Embodiment>> In this embodiment, an example will be described in which, when it is detected that the ADF unit 360 has been opened while a document is present in the ADF, an ADF open error screen 1140 is displayed at that time. Because the basic configuration and processing are the same as those described in the first embodiment, a description thereof will be omitted here, and the description will focus on the differences. Note that the form described in the second embodiment may be combined with the third embodiment.

[0069] Fig. 9 is a diagram showing an example of a display screen of the operation panel 303. Fig. 9 shows an example of an ADF open error screen 1140 in this embodiment. A title 1141 indicating the type of error is displayed at the top of the screen. A message 1142 explaining the solution is displayed below the title 1141. Unlike Fig. 5(e), function buttons are not displayed in Fig. 9. In the ADF open error screen 1140 of Fig. 9, when scanning with the ADF, a message 1142 is displayed notifying the user that the ADF will be closed and that pressing the start key will start scanning with the FB.

[0070] 10 is a state transition diagram showing an example of state transitions of the multifunction peripheral 300. The initial state in the state transition diagram is a power-off state S3100. When a power-on operation is detected on the operation panel 303 of the multifunction peripheral 300 in the power-off state S3100, the multifunction peripheral 300 performs power-on processing and transitions to a power-on state S3101. When the multifunction peripheral 300 enters the power-on state S3101, the multifunction peripheral 300 first transitions to a home screen display state S3102. In the home screen display state S3102, the home screen 1100 is displayed. When the copy mode selection button 1101 on the screen is touched in the home screen display state S3102, the multifunction peripheral 300 transitions to a copy standby state S3103.

[0071] Upon entering the copy standby state S3103, the multifunction peripheral 300 first transitions to an ADF no-original state S3104 which displays an ADF no-original standby screen 1110. If the presence of an ADF original is detected in the ADF no-original state S3104, the multifunction peripheral 300 transitions to an ADF original present state S3105 which displays an ADF original present standby screen 1120. If the absence of an ADF original is detected in the ADF original present state S3105, the multifunction peripheral 300 transitions to the ADF no-original state S3104.

[0072] When the MFP 300 detects that the ADF is open in the ADF original present state S3105, the MFP 300 transitions to an ADF open error state S3106, which displays the ADF open error screen 1140 of Fig. 9. When the MFP 300 detects that the ADF is closed in the ADF open error state S3106, the MFP 300 transitions to the ADF original present state S3105.

[0073] When the start key 1005 or 1006 is pressed in the ADF no document state S3104, the multifunction device 300 starts an FB document reading operation and transitions to an FB reading operation state S3107. In the FB reading operation state S3107, an FB copy operation screen 1150 is displayed. When the start key 1005 or 1006 is pressed in the ADF document present state S3105, the multifunction device 300 starts an ADF document reading operation and transitions to an ADF reading operation state S3108. In the ADF reading operation state S3108, an ADF copy operation screen 1160 is displayed. When the start key 1005 or 1006 is pressed in the ADF open error state S3106, the multifunction device 300 starts an FB document reading operation and transitions to an FB reading operation state S3107.

[0074] In this embodiment, as described in the first embodiment, the multifunction device 300 can also transition to a copy standby state according to the presence or absence of an original in the ADF and the open / closed state of the ADF when the copy button is pressed. In other words, the multifunction device 300 may transition to a state without going through the ADF no original state S3104.

[0075] As described above, this embodiment also improves the operability of an image processing apparatus having the FB reading unit 350 and the ADF unit 360. That is, this embodiment also makes it possible to notify the user of a corrective action in an easy-to-understand manner when it is detected that a document is present in the document feed tray 361 and that the ADF unit 360 has been opened. Furthermore, based on the operation in the ADF open error state S3106, the user can select whether to read from the ADF or the FB according to their intention.

[0076] <<Fourth Embodiment>> In this embodiment, an example will be described in which an indicator indicating the presence or absence of an ADF document and an indicator indicating the presence or absence of an FB document are respectively arranged on the copy standby screen. Because the basic configuration and processing are the same as the example described in the first embodiment, explanation will be omitted here and the explanation will focus on the differences. Note that the form described in the third embodiment may be combined with this embodiment.

[0077] The presence or absence of an FB document can be detected using the CIS sensor unit 351. That is, by having the CIS sensor unit 351 read the FB document glass 352, it is possible to detect whether or not a document is present on the FB document glass 352. The method for detecting the presence or absence of an FB document is not limited to this example, and any method can be used.

[0078] 11A and 11B are diagrams showing examples of the display screen of the operation panel 303. Fig. 11A shows an example of a copy standby screen 1210 when there are no ADF originals and no FB originals. An ADF indicator 1216 and an FB indicator 1217 are both displayed in a grayed-out state.

[0079] 11B shows an example of a standby screen 1220 for when an ADF document is present and an FB document is not present, which is a copy standby screen when an ADF document is present and an FB document is not present. The ADF indicator 1226 is displayed in highlight, and the FB indicator 1227 is displayed in grayout.

[0080] 11C shows an example of a standby screen 1230 when there is no ADF document and there is an FB document, which is a copy standby screen when there is no ADF document and there is an FB document. The ADF indicator 1236 is displayed in grayout, and the FB indicator 1237 is displayed in highlight.

[0081] 11(d) shows an example of an ADF priority state standby screen 1240, which is a copy standby screen in the ADF priority state when both an ADF document and an FB document are present. Both the ADF indicator 1246 and the FB indicator 1247 are highlighted. A triangular mark is displayed on the left side of the ADF indicator 1246, visually indicating that the ADF priority state is active. When the FB indicator 1247 is touched on the ADF priority state standby screen 1240, the screen transitions to an FB priority state standby screen 1250 in the FB priority state.

[0082] 11(e) shows an example of an FB priority state standby screen 1250, which is a copy standby screen in the FB priority state when there is both an ADF document and an FB document. Both the ADF indicator 1256 and the FB indicator 1257 are highlighted. A triangular mark is displayed on the left side of the FB indicator 1257, visually indicating that it is in the FB priority state. When the ADF indicator 1256 is touched on the FB priority state standby screen 1250, the screen transitions to the ADF priority state standby screen 1240.

[0083] 12 is a state transition diagram showing an example of state transitions of the multifunction peripheral 300. The initial state in the state transition diagram is a power-off state S3200. When a power-on operation is detected on the operation panel 303 of the multifunction peripheral 300 in the power-off state S3200, the multifunction peripheral 300 performs power-on processing and transitions to a power-on state S3201. Upon entering the power-on state S3201, the multifunction peripheral 300 transitions to a home screen display state S3202. In the home screen display state S3202, the multifunction peripheral 300 displays the home screen 1100. When the copy mode selection button 1101 on the screen is touched in the home screen display state S3202, the multifunction peripheral 300 transitions to a copy standby state S3203.

[0084] Upon entering the copy standby state S3203, the multifunction peripheral 300 enters an ADF no-original, FB no-original state S3204, which displays the copy standby screen 1210 for when there is no ADF original and no FB original. If it is detected that there is an ADF original in the ADF no-original, FB no-original state S3204, the multifunction peripheral 300 transitions to an ADF with original, FB with no original state S3205, which displays the ADF with original, FB with no original standby screen 1220. If it is detected that there is no ADF original in the ADF with original, FB with no original state S3205, the multifunction peripheral 300 transitions to the ADF with no original, FB with no original state S3204. If it is detected that there is an FB original in the ADF no-original, FB no-original state S3204, the multifunction peripheral 300 transitions to an ADF with no original, FB with original state S3206, which displays the ADF with no original, FB with original standby screen 1230. When it is detected that there is no FB document in the ADF document-free / FB document-present state S3206, the multifunction peripheral 300 transitions to the ADF document-free / FB document-free state S3204.

[0085] When the presence of an FB document is detected in the ADF document-present, FB document-absent state S3205, the multifunction peripheral 300 transitions to the ADF document-present, FB document-present state S3207. At this time, the multifunction peripheral 300 transitions to the FB priority state S3209, which displays the FB priority state standby screen 1250. The state transitioning from the ADF document-present, FB document-absent state S3205 to the ADF document-present, FB document-present state S3207 means that an ADF document is present and the user has placed an FB document 355 on the FB platen glass 352. In other words, it is highly likely that the user wishes to read the FB document 355 that was placed later. For this reason, when the multifunction peripheral 300 transitions from the ADF document-present, FB document-absent state S3205 to the ADF document-present, FB document-present state S3207, the multifunction peripheral 300 transitions to the FB priority state S3209, which displays the FB priority state standby screen 1250.

[0086] When the presence of an ADF document is detected in the ADF document-free, FB document-present state S3206, the MFP 300 transitions to the ADF document-present, FB document-present state S3207. At this time, the MFP 300 transitions to the ADF priority state S3208, which displays the ADF priority state standby screen 1240. The state transitioning from the ADF document-free, FB document-present state S3206 to the ADF document-present, FB document-present state S3207 means that an FB document is present and the user has placed an ADF document 370 in the ADF unit 360. In other words, it is highly likely that the MFP 300 wishes to scan the ADF document 370 that was placed later. Therefore, the MFP 300 that transitioned from the ADF document-free, FB document-present state S3206 to the ADF document-present, FB document-present state S3207 transitions to the ADF priority state S3208, which displays the ADF priority state standby screen 1240.

[0087] When in the ADF document present / FB document present state S3207, the priority state can be switched using the ADF indicator and the FB indicator. When the FB indicator 1247 is touched in the ADF priority state S3208, the multifunction peripheral 300 transitions to the FB priority state S3209. When the ADF indicator 1256 is touched in the FB priority state S3209, the multifunction peripheral 300 transitions to the ADF priority state S3208. When the start key 1005 or 1006 is pressed in the ADF document present / FB document not present state S3205 or the ADF priority state S3208, the ADF reading operation is started and the state transitions to the ADF reading operation state S3211. In the ADF reading operation state S3211, the ADF copy operation in progress screen 1160 is displayed.

[0088] When the start key 1005 or 1006 is pressed in the ADF no document / FB document present state S3206 or in the FB priority state S3209, the FB reading operation starts and the state transitions to the FB reading operation state S3210. In the FB reading operation state S3210, the FB copy operation in progress screen 1150 is displayed.

[0089] In this embodiment, as described in the first embodiment, the multifunction device 300 can also transition to a copy standby state in accordance with the presence or absence of an ADF document and an FD document when the copy button is pressed. In other words, the multifunction device 300 may transition to a state without going through the state S3204 where there is neither an ADF document nor an FB document.

[0090] As described above, according to this embodiment, it is possible to visually display the presence or absence of an ADF document and the presence or absence of an FB document. When an ADF document and an FB document are present, it is possible to visually display which document will be read. Furthermore, by operating the display screen, it becomes possible to change which document will be read according to the user's intention.

[0091] <<Other embodiments>> The present invention can also be realized by supplying a program that realizes one or more functions of the above-described embodiments to a system or device via a network or a storage medium, and having one or more processors in the computer of the system or device read and execute the program. It can also be realized by a circuit (e.g., ASIC) that realizes one or more functions.
