An image forming apparatus such as a multifunction peripheral includes an image reading unit that reads a document and generates image data of the document. When an image forming apparatus including an image reading unit is used, a job accompanying reading of a document such as a copy job (hereinafter simply referred to as a job) can be executed.

An image forming apparatus including an image reading unit is generally provided with an operation panel in order to accept a start operation for instructing execution of a job from a user. The operation panel displays a predetermined acceptance screen, and accepts a start operation (job execution instruction) from the user in that state.

For example, the conventional image forming apparatus stops the screen display by the operation panel in the power saving mode. When the operation panel stops the screen display, the conventional image forming apparatus accepts the operation as a display return operation and cancels the screen display stop state when the operation panel is operated ( Start screen display on the operation panel).

For example, when the conventional image forming apparatus is in the power saving mode (when the operation panel stops displaying the screen), no operation other than the display return operation is accepted. In this configuration, when the image forming apparatus is in the power saving mode, even if an operation corresponding to the start operation is performed on the operation panel, the operation is not accepted as the start operation (job execution instruction), and the display return operation is performed. Accepted. That is, the screen is displayed on the operation panel, but the job is not executed.

Therefore, in the conventional image forming apparatus, when the image forming apparatus is in the power saving mode, some operation is performed on the operation panel, and then the operation panel starts displaying, and then the operation panel is again displayed. Unless the operation (start operation) is performed on the image forming apparatus, it is impossible to instruct the image forming apparatus to execute the job. For this reason, it is not convenient for the user.

SUMMARY An advantage of some aspects of the invention is that an image forming apparatus and an image forming apparatus capable of improving the convenience of a user who intends to instruct the image forming apparatus in the power saving mode to execute a job. An object is to provide a method for controlling an apparatus.

In order to achieve the above object, an image forming apparatus according to a first aspect of the present invention is an image forming apparatus equipped with a first mode and a second mode that consumes less power than the first mode, and supplies power. In the first mode, which includes a power supply unit and an image reading unit that reads the document and generates image data of the document and receives normal power supply from the power supply unit, it is possible to execute a job that involves reading the document by the image reading unit. In the second mode in which the power supply from the power supply unit is more limited than in the first mode while waiting in a job ready state, the job execution unit that does not execute the job and the first mode that receives normal power supply from the power supply unit In some cases, user operations are accepted while the screen is displayed, while in the second mode, where the power supply from the power supply unit is more restricted than in the first mode, the user is not displayed without displaying the screen. An operation panel for accepting an operation of chromatography, and a control unit. The operation panel has a start key that is a hardware key for receiving a job execution instruction from the user, and the control unit executes a job from the power supply unit when an operation is performed on the start key in the second mode. When the job execution unit returns to the job ready state, the job execution unit causes the job execution unit to execute the job.

An image forming apparatus control method according to a second aspect of the present invention includes a first mode and a second mode that consumes less power than the first mode, a power supply unit that supplies power, and a document by reading the document. In the first mode, which includes an image reading unit that generates image data and receives normal power supply from the power supply unit, the power supply unit waits in a job ready state in which a job involving reading of a document by the image reading unit is possible In the second mode, where the power supply from the first mode is more restricted than in the first mode, the job execution unit that does not execute the job and the first mode that receives the normal power supply from the power source unit display the screen in the user's state. An operation panel that accepts a user's operation without displaying a screen during the second mode in which power supply from the power supply unit is restricted as compared with the first mode, while accepting an operation; In the second mode, when an operation is performed on a start key that is a hardware key for receiving a job execution instruction from a user in the second mode, a normal operation is performed from the power supply unit to the job execution unit. The method includes a step of returning the job execution unit to a job ready state by supplying power, and a step of causing the job execution unit to execute a job when the job execution unit returns to the job ready state.

According to the configuration of the present invention, when the start key is operated in the second mode, the job execution unit returns to the job ready state and does not need to be operated again for the start key. The returned job execution unit executes the job. That is, if the operation performed in the second mode is an operation on the start key, the operation is accepted as a job execution instruction. Therefore, when the user instructs the image forming apparatus to execute a job, even if the image forming apparatus is in the second mode at that time, the user only needs to perform the operation for the start key once. Can be instructed. Thereby, since it is not necessary to perform operation with respect to an operation panel many times, a user's convenience improves.

Further, in the conventional configuration, when the image forming apparatus is in the second mode, the operation panel does not display a screen on the operation panel by performing some operation on the operation panel. Cannot instruct execution. Therefore, it is necessary for the user to wait until a screen is displayed on the operation panel (a waiting time occurs). On the other hand, in the configuration of the present invention, since the operation on the start key performed in the second mode (when the screen is not displayed on the operation panel) is accepted as a job execution instruction, no waiting time occurs. Accordingly, the job can be promptly started by the image forming apparatus.

In the configuration of the present invention, it is possible to improve the convenience of the user who intends to instruct the second mode image forming apparatus to execute the job.

<Configuration of MFP>
As shown in FIG. 1, the multifunction peripheral 100 according to the present embodiment includes a printing unit 10 and an image reading unit 20. The multifunction peripheral 100 corresponds to an “image forming apparatus”.

The printing unit 10 conveys the paper P along the paper conveyance path 10P. The printing unit 10 forms a toner image based on image data of an image to be printed. Then, the printing unit 10 prints a toner image on the paper P being conveyed. For example, the printing unit 10 includes a paper feeding unit 11 that feeds the paper P stored in a paper cassette to the paper conveyance path 10P, an image forming unit 12 that forms a toner image and transfers the toner image to the paper P, and The fixing unit 13 is configured to fix the toner image transferred to the paper P to the paper P.

The image reading unit 20 includes optical members such as a lamp 21 and an image sensor 22 and optically reads the document D. Optical system members such as the lamp 21 and the image sensor 22 are accommodated in a housing (reading housing) of the image reading unit 20. Note that contact glasses G1 and G2 are fitted on the upper surface of the reading housing. The contact glass G1 is a contact glass for conveyance reading, and the contact glass G2 is a contact glass for placement reading.

Further, the image reading unit 20 includes a document conveying unit 30. The document transport unit 30 is supported to be openable and closable with respect to the upper surface of the reading housing. The document transport unit 30 includes a document transport path 30P, a document placement tray 31, and a document discharge tray 32. The document transport path 30P extends from the document placement tray 31 to the document discharge tray 32 via a predetermined position on the contact glass G1 (reading position RP for transport reading). Then, the document transport unit 30 feeds the document D placed on the document placement tray 31 to the document transport path 30P, transports the document D along the document transport path 30P, and feeds the document D to the document discharge tray 32. D is discharged.

In the conveyance reading, the document D is placed on the document placing tray 31 by the user. The document transport unit 30 feeds the document D on the document loading tray 31 to the document transport path 30P and transports it along the document transport path 30P. As a result, the document D passes through the reading position RP on the contact glass G1. Then, the image reading unit 20 reads the document D passing through the reading position RP, and generates image data of the read document D.

In the placement reading, the document D is placed on the contact glass G2 by the user. The image reading unit 20 reads the document D placed on the contact glass G2, and generates image data of the read document D. At this time, the document D placed on the contact glass G <b> 2 can be pressed by the document transport unit 30.

Here, the multifunction machine 100 includes a set sensor SS for detecting whether or not the document D to be read by the image reading unit 20 is set in the multifunction machine 100 (the presence or absence of the document D to be read). The set sensor SS includes a first set sensor SS1 for detecting whether or not the document D to be conveyed and read is set on the multifunction peripheral 100, and the document D to be placed and scanned on the multifunction peripheral 100. And a second set sensor SS2 (see FIG. 2) for detecting whether or not it is set.

The first set sensor SS1 is installed on the document placing tray 31 as shown in FIG. For example, the first set sensor SS1 is a transmissive optical sensor that detects an actuator (not shown) rotatably attached to the document placing tray 31. When the document D is placed on the document placement tray 31, the actuator moves downward by being pressed by the document D and blocks (or opens) the optical path of the first set sensor SS1. Further, when the document D disappears from the document placement tray 31, the actuator moves upward by releasing the pressing by the document D, and blocks (or opens) the optical path of the first set sensor SS1. That is, the first set sensor SS1 changes the output value between when the document D is placed on the document placement tray 31 and when it is not placed. Therefore, based on the output value of the first set sensor SS1, it is possible to detect whether or not the document D is placed on the document placement tray 31 (the presence or absence of the document D to be conveyed and read).

As shown in FIG. 2, the second set sensor SS2 is installed inside the reading housing of the image reading unit 20 (below the contact glass G2). For example, the second set sensor SS2 is a reflective optical sensor. In addition, a plurality of second set sensors SS2 are provided, and are arranged in a row at intervals from each other along the sub-scanning direction. Thereby, when the document D is placed on the contact glass G2, at least one of the plurality of second set sensors SS2 changes the output value. Therefore, based on the output value of the second set sensor SS2, it is possible to detect whether or not the document D is placed on the contact glass G2 (the presence or absence of the document D to be placed and read). In this configuration, the size of the document D placed on the contact glass G2 in the sub-scanning direction is also detected by specifying the second set sensor SS2 whose output value has changed among the plurality of second set sensors SS2. can do.

Returning to FIG. 1, the multifunction peripheral 100 includes an operation panel 40. For example, the operation panel 40 is installed in a reading housing of the image reading unit 20.

The operation panel 40 includes a touch panel display 41 as shown in FIG. The touch panel display 41 includes, for example, a liquid crystal display panel with a backlight and a touch panel disposed on the surface of the liquid crystal display panel. The touch panel display 41 displays a screen on which software keys and the like are arranged, and accepts a touch operation on the display screen (software key) from the user.

Furthermore, the operation panel 40 includes a plurality of hardware keys 42. For example, a function selection key 43 for receiving an instruction to select a function to be used from a plurality of types of functions (copy function, box function, and transmission function) installed in the multi-function device 100, a job (copy function) that reads a document D , A start key 44 for accepting an execution instruction of a job that uses one of the box function and the transmission function) from a user, a numeric keypad 45 (corresponding to a “numerical value input key”) for accepting a numeric input from the user, and A hardware key 42 such as a call key 46 for receiving a call of a pre-registered program (registered setting value) from the user is provided on the operation panel 40. The function selection key 43 includes three keys respectively corresponding to the copy function, the box function, and the transmission function. The number of call keys 46 is also three. However, the number of call keys 46 is not particularly limited, and may be two or less, or may be four or more.

Further, as shown in FIG. 4, the multi-function device 100 includes a control unit 110. The control unit 110 is connected to the printing unit 10 and the image reading unit 20, and controls the printing operation of the printing unit 10 and also controls the image reading operation of the image reading unit 20. It should be noted that the control unit 110 performs control for placement reading when the placement reading is executed. On the other hand, when carrying out conveyance reading, the control unit 110 performs conveyance reading control. At this time, the control unit 110 also controls the document transport operation of the document transport unit 30.

Also, the control unit 110 is connected to the set sensor SS (receives the output of the set sensor SS). Then, the control unit 110 determines whether or not the document D to be read is set on the multifunction peripheral 100 based on the output value of the set sensor SS.

Specifically, if the output value of the first set sensor SS1 is a value indicating the presence of the document D, the control unit 110 sets the document D to be conveyed and read in the multifunction peripheral 100 ( It is determined that the document D is placed on the document placement tray 31). On the other hand, if the output value of the second set sensor SS2 is a value indicating the presence of the document D, the control unit 110 sets the document D to be placed and read on the multifunction peripheral 100 (contact). It is determined that the document D is placed on the glass G2.

Further, the control unit 110 is connected to the operation panel 40. Then, the control unit 110 controls the display operation of the touch panel display 41. Further, the control unit 110 detects a touch operation on the touch panel display 41 (software key) and also detects a pressing operation on the hardware key 42.

The control unit 110 includes a CPU 111, a memory 112, an image processing module 113, and the like. The CPU 111 executes processing for controlling the multifunction peripheral 100 based on the control program and data. The memory 112 stores a control program and data for operating the CPU 111.

The image processing module 113 includes an image processing circuit and a memory. For example, in a job involving reading of the document D, the image data of the document D obtained by reading the document D by the image reading unit 20 is temporarily stored in the memory 112. Then, the image processing module 113 performs image processing on the image data of the document D, thereby converting the image data of the document D into data corresponding to the execution job (function job selected by the user).

For example, when the execution job is a copy job (a job involving reading of the document D), the image processing module 113 performs an exposure process (an electrostatic latent based on the image data of the document D) performed in the image forming unit 12 of the printing unit 10. Data for exposure for controlling (processing for forming an image) is generated. Thereafter, the control unit 110 outputs the exposure data to the printing unit (image forming unit 12). Then, the printing unit 10 develops the electrostatic latent image obtained by the exposure process based on the exposure data into a toner image, and prints (transfers) the developed toner image onto the paper P, thereby printing the printed paper P Is discharged.

Further, the multifunction device 100 includes a storage unit 50 and a communication unit 60. Storage unit 50 and communication unit 60 are each connected to control unit 110.

The storage unit 50 includes a non-volatile storage device such as a ROM (EEPROM or the like) or an HDD. The control unit 110 reads data from the storage unit 50 and writes data to the storage unit 50. For example, when the execution job is a box job (a job involving reading of the document D), the control unit 110 causes the storage unit 50 to store the image data of the document D obtained by reading the document D by the image reading unit 20. .

The communication unit 60 includes a communication circuit, a memory, a communication connector, and the like. The control unit 110 communicates with the external device 300 via the communication unit 60. For example, a personal computer, a facsimile machine, or the like can be communicably connected to the multifunction device 100. When such an external device 300 is communicably connected to the multifunction peripheral 100, a transmission job (a job that involves reading the document D) can be executed. When executing the transmission job, the control unit 110 causes the communication unit 60 to transmit the image data of the document D obtained by reading the document D by the image reading unit 20 to the external device 300.

Further, the multifunction machine 100 includes a power supply unit 120. The power supply unit 120 is connected to a commercial power supply. The power supply unit 120 includes a power supply circuit that generates a voltage, a power supply control circuit that controls power supply, and the like. The power supply unit 120 operates each unit of the multifunction peripheral 100 such as the printing unit 10, the image reading unit 20 (including the document conveyance unit 30), the operation panel 40, the storage unit 50, the communication unit 60, and the control unit 110. Generate voltage. The power supply unit 120 is connected to the control unit 110, receives an instruction from the control unit 110, and switches the power supply mode. The power supply mode will be described later in detail.

<Executing a job that involves reading a document>
The user selects which function to use from among a plurality of types of functions (copy function, box function, and transmission function) installed in the multifunction peripheral 100. The operation panel 40 accepts a function selection operation for selecting a function to be used from a plurality of types of functions. In order to cause the operation panel 40 to accept a function selection operation, a plurality of function selection keys 43 (see FIG. 3) respectively corresponding to a plurality of types of functions are provided on the operation panel 40. Then, the operation panel 40 accepts a pressing operation on any one of the plurality of function selection keys 43 as a function selection operation.

When the control unit 110 detects a function selection operation on the operation panel 40, the setting value of the function corresponding to the function selection key 43 that is the operation target of the function selection operation (execution condition when executing a job that uses the function) The operation panel 40 is allowed to accept an operation for setting (). At this time, the operation panel 40 displays a setting screen 410 (see FIGS. 5 to 7), and accepts an operation for setting the setting value of the function selected by the function selection operation from the user.

For example, when the copy function is selected, the operation panel 40 displays a copy screen 410C as shown in FIG. The copy screen 410C is a screen for accepting the setting value setting of the copy function from the user. On this copy screen 410C, for example, setting values of a plurality of setting items relating to the copy function such as “paper size” and “density” can be set. If a numerical value is input by performing an operation on the numeric keypad 45 while the copy screen 410C is displayed, the input numerical value can be set as the number of copies to be printed.

When the box function is selected, the operation panel 40 displays a box screen 410B as shown in FIG. The box screen 410B is a screen for accepting the setting value of the box function from the user. On this box screen 410B, a data storage destination can be set.

When the transmission function is selected, the operation panel 40 displays a transmission screen 410S as shown in FIG. The transmission screen 410S is a screen for accepting the setting value of the transmission function from the user. On the transmission screen 410S, for example, a data transmission destination can be set.

Of the plurality of setting screens 410, the setting screen 410 corresponding to the user-specified designation function is preset as an initial screen, and initial screen information indicating which of the plurality of setting screens 410 is the initial screen is stored in the memory 112. Is remembered. Then, the control unit 110 displays the setting screen 410 set as the initial screen among the plurality of setting screens 410 when the multifunction device 100 is activated or when the multifunction device 100 returns from the power saving mode to the normal mode. Is first performed on the operation panel 40. Here, the normal mode corresponds to a “first mode”, and the power saving mode corresponds to a “second mode”. The normal mode and the power saving mode will be described later in detail.

When the control unit 110 detects a pressing operation on the start key 44 while the setting screen 410 is being displayed, the control unit 110 determines whether or not the document D is set on the multifunction peripheral 100 based on the output value of the set sensor SS. As a result, when it is determined that the document D is set in the multifunction peripheral 100, the control unit 110 performs a process for executing a job having a function corresponding to the currently displayed setting screen 410.

When the execution job is a copy job (when the display screen when the start key 44 is pressed is the copy screen 410C), the control unit 110 causes the printing unit 10 and the image reading unit 20 to execute the copy job. That is, the image reading unit 20 reads the document D and generates image data of the document D. The printing unit 10 forms a toner image based on the image data of the document D read by the image reading unit 20 and prints the formed toner image on the paper P.

At this time, if the document D is placed on the document placing tray 31, the control unit 110 causes the image reading unit 20 (document feeding unit 30) to carry and read the document D on the contact glass G2. Is placed, the image reading unit 20 is caused to perform placement reading. The same applies to the box job and the transmission job.

When the execution job is a box job (when the display screen when the start key 44 is pressed is the box screen 410B), the control unit 110 causes the image reading unit 20 and the storage unit 50 to execute the box job. That is, the image reading unit 20 reads the document D and generates image data of the document D. The storage unit 50 stores image data of the document D read by the image reading unit 20.

When the execution job is a transmission job (when the display screen when the start key 44 is pressed is the transmission screen 410S), the control unit 110 causes the image reading unit 20 and the communication unit 60 to execute the transmission job. That is, the image reading unit 20 reads the document D and generates image data of the document D. In addition, the storage unit 50 transmits the image data of the document D read by the image reading unit 20 to the external device 300.

Thus, in the copy job, the printing unit 10 and the image reading unit 20 execute the job. In the box job, the image reading unit 20 and the storage unit 50 execute the job. In the transmission job, the image reading unit 20 and the communication unit 60 execute the job. That is, the printing unit 10, the image reading unit 20, the storage unit 50, and the communication unit 60 correspond to a “job execution unit”. In the following description, the printing unit 10, the image reading unit 20, the storage unit 50, and the communication unit 60 may be collectively referred to as a job execution unit 100J.

Here, the storage unit 50 executes the setting value (the job using the selection function) of the selection function selected by the user from a plurality of types of functions (copy function, box function, and transmission function) installed in the MFP 100. Is stored in a registered set value registered by the user (hereinafter referred to as a setting program). The setting program is associated with one of the plurality of call keys 46. Note that the maximum number of setting programs that can be registered is the same as the number of call keys 46 provided on the operation panel 40. When a plurality of setting programs are registered, the plurality of setting programs are associated with different call keys 46, respectively.

When a pressing operation is performed on any of the plurality of calling keys 46, the control unit 110 calls a setting program corresponding to the calling key 46 that has received the pressing operation, and sets a function setting value based on the calling setting program. Perform the setting process. At this time, the control unit 110 recognizes the selection function and the registered setting value indicated by the called setting program, and sets the setting value of the selection function as the registered setting value. Thereafter, when a pressing operation on the start key 44 is performed, the control unit 110 causes the job execution unit 100J to execute a job of the selection function.

<Operation acceptance in power saving mode>
The multi-function device 100 includes a normal mode and a power saving mode (sleep mode) as power supply modes. The normal mode is a mode in which the power supply unit 120 supplies normal power. The power saving mode is a mode (a mode for suppressing power consumption) in which the power supply performed by the power supply unit 120 is limited as compared with the normal mode. That is, the power consumption in the power saving mode is lower than in the normal mode.

Control unit 110 determines whether or not a mode transition condition set in advance as a condition for shifting from the normal mode to the power saving mode is satisfied in the normal mode. When the mode transition condition is satisfied, the control unit 110 instructs the power supply unit 120 to cause the multifunction peripheral 100 to transition from the normal mode to the power saving mode. For example, the control unit 110 counts the unused time, which is the time that has passed without the MFP 100 being used, and determines that the mode transition condition is satisfied when the unused time exceeds a predetermined threshold time.

In the normal mode, the power supply unit 120 supplies the job execution unit 100J with a normal power supply so that the job execution unit 100J can execute a job. That is, the job execution unit 100J stands by in a job ready state in the normal mode. On the other hand, the power supply unit 120 restricts the power supply to the job execution unit 100J more than the power supply in the normal mode in the power saving mode. At this time, the job execution unit 100J does not execute the job.

Specifically, the power supply unit 120 stops the power supply to each of the printing unit 10, the image reading unit 20 (including the document transport unit 30), and the storage unit 50 in the power saving mode. Further, the power supply unit 120 does not completely stop the power supply to the communication unit 60 but partially stops in the power saving mode. The reason why the power supply to the communication unit 60 is not completely stopped is to cause the communication unit 60 to receive transmission data from the external device 300 when data is transmitted from the external device 300 to the multifunction device 100 in the power saving mode. It is.

The operation panel 40 receives normal power supply from the power supply unit 120 in the normal mode. Thereby, the operation panel 40 receives a user operation (touch operation on the touch panel display 41 and pressing operation on the hardware key 42) in a state where a screen such as the setting screen 410 is displayed in the normal mode.

In addition, when the operation panel 40 is in the power saving mode, the power supply from the power supply unit 120 is more limited than the power supply in the normal mode. That is, the power supply unit 120 partially stops power supply to the operation panel 40 in the power saving mode. For example, the power supply unit 120 stops power supply to the liquid crystal display panel (backlight) of the touch panel display 41 in the power saving mode. Therefore, the operation panel 40 accepts a user operation without displaying a screen when in the power saving mode.

The control unit 110 determines whether or not an operation (touch operation on the touch panel display 41 and pressing operation on the hardware key 42) has been performed on the operation panel 40 in the power saving mode. As a result, when determining that an operation has been performed on the operation panel 40 in the power saving mode, the control unit 110 causes the power unit 120 to perform normal power supply to the operation panel 40 and causes the operation panel 40 to perform a setting screen 410. Is displayed. In other words, the control unit 110 performs a return process (hereinafter referred to as a display return process) for returning the screen display by the operation panel 40. At this time, the operation panel 40 displays the setting screen 410 set as an initial screen among the plurality of setting screens 410.

Here, the control unit 110 recognizes which of the plurality of hardware keys 42 has been operated when the operation panel 40 is operated in the power saving mode. When the operation performed on the operation panel 40 in the power saving mode is a pressing operation on the start key 44, the control unit 110 determines that the first operation has been performed. When the operation performed on the operation panel 40 in the power saving mode is a pressing operation on either the numeric keypad 45 or the call key 46, the control unit 410 determines that the second operation has been performed.

When determining that the first operation (pressing operation on the start key 44) has been performed in the power saving mode, the control unit 110 causes the power execution unit 100J to perform normal power supply to the job execution unit 100J in addition to the display restoration process. As a result, a return process for returning the job execution unit 100J to the job ready state (hereinafter referred to as a main body return process) is performed. As a result, the display of the setting screen 410 by the operation panel 40 is restored, and the job execution unit 100J is restored to the job ready state. That is, the multifunction device 100 returns from the power saving mode to the normal mode.

Then, when the job execution unit 100J returns to the job ready state (when the multifunction peripheral 100 returns to the normal mode), the control unit 110 accompanies the reading of the document D even when the start key 44 is not pressed again. The job is executed by the job execution unit 100J. At this time, the control unit 110 recognizes, as a target function, a function corresponding to the setting screen 410 set as an initial screen among a plurality of types of functions (the job execution unit 100J executes a job of the target function). Further, the control unit 110 sets the setting value of the target function to the default setting value.

Note that when the control unit 110 determines that the first operation (pressing operation on the start key 44) has been performed in the power saving mode, the document D to be read is set in the multifunction peripheral 100 based on the output value of the set sensor SS. It is judged whether it is done. As a result, if it is determined that the document D to be read is set in the multi-function peripheral 100, the control unit 110 performs a main body restoration process and causes the job execution unit 110J that has returned to the job ready state to execute the job.

On the other hand, if it is determined that the document D to be read is not set in the multifunction peripheral 100, the control unit 110 performs only the display recovery process without performing the main body recovery process. Therefore, the job is not executed. In this case, the display of the setting screen 410 on the operation panel 40 is restored, but the job execution unit 100J does not return to the job ready state, and thus the multifunction peripheral 100 does not completely return to the normal mode. That is, the multi-function device 100 is in a power saving display mode in which the operation panel 40 displays a screen without returning the job execution unit 100J to the job ready state.

After the multifunction device 100 enters the power saving display mode, it is detected that the document D to be read is set on the multifunction device 100 before the unused time exceeds the predetermined threshold time, and the start key 44 is pressed. When the operation is detected, the control unit 110 returns the multifunction peripheral 100 to the normal mode by performing the main body return process (returns the job execution unit 100J to the job ready state). Then, the control unit 110 causes the job execution unit 100J that has returned to the job ready state to execute the job. When the unused time exceeds a predetermined threshold time after the multifunction device 100 enters the power saving display mode, the control unit 110 instructs the power supply unit 120 to shift the multifunction device 100 to the power saving mode.

When it is determined that the second operation (pressing operation on either the numeric keypad 45 or the call key 46) has been performed in the power saving mode, the control unit 110 sets a function setting value in addition to the display return processing. I do. Note that when the document D to be read is not set in the multifunction peripheral 100, the control unit 110 performs only display return processing without performing function setting processing. That is, in this case, the multifunction peripheral 100 is in the power saving display mode.

When the second operation is a pressing operation on the numeric keypad 45, the control unit 110 performs a copy number setting process for setting the numerical value input by the pressing operation on the numeric keypad 45 as the number of copies as a function setting process. That is, a pressing operation on the numeric keypad 45 performed in the power saving mode (when the operation panel 40 is not displaying the setting screen 410) is accepted as an operation for returning the screen display by the operation panel 40, and the operation is printed. It is accepted as an operation for setting the number of copies.

Thereafter, when a pressing operation on the start key 44 is performed, the control unit 110 returns the job execution unit 100J (the printing unit 10 and the image reading unit 20) to a job ready state by performing a main body return process. Then, when the printing unit 10 and the image reading unit 20 return to the job ready state, the control unit 110 causes the image reading unit 20 to read the document D to generate image data of the document D. In addition, the control unit 110 causes the printing unit 10 to perform printing based on the image data of the document D obtained by reading the document D by the image reading unit 20. At this time, the printing unit 10 performs printing for the number of copies set by the number setting process by the control unit 110.

Here, when the second operation (pressing operation on the numeric keypad 45) is performed in the power saving mode, the display return process may not be performed. In this configuration, when the operation is performed on the start key 44 after the operation on the numeric keypad 45 (after the user inputs the number of copies) in the power saving mode, the control unit 110 operates the operation panel. The printing unit 10 is caused to perform printing without causing the printing unit 10 to display a screen. At this time, the printing unit 10 performs printing for the number of copies input by the user.

Alternatively, when the second operation (pressing operation on the numeric keypad 45) is performed in the power saving mode, a process of displaying only the first predetermined information on the operation panel 40 may be performed as the display return process. In the case of this configuration, for example, when the operation is performed on the start key 44 after the operation is performed on the numeric keypad 45 (after the user inputs the number of copies) in the power saving mode, the control unit 110 Only the numerical value (corresponding to the first predetermined information) indicating the number of copies set in the number of copies setting process is displayed on the operation panel 40 to cause the printing unit 10 to perform printing. At this time, the printing unit 10 performs printing for the number of copies input by the user.

When the second operation is a pressing operation on the call key 46, the control unit 110 calls the setting program corresponding to the call key 46 that has received the pressing operation in the power saving mode as the function setting process, and the called setting program The call processing for setting the setting value of the function is performed based on the above. That is, the control unit 110 recognizes the selection function and the registered setting value indicated by the called setting program, and sets the setting value of the selection function as the registered setting value.

Thereafter, when a pressing operation is performed on the start key 44, the control unit 110 returns the job execution unit 100J to a job ready state by performing a main body return process. Then, when the job execution unit 100J returns to the job ready state, the control unit 110 causes the job execution unit 100J to execute the job of the selection function. At this time, the job execution unit 100J executes the job under an execution condition corresponding to the registered setting value.

Here, when the second operation (pressing operation on the call key 46) is performed in the power saving mode, a process of displaying only the second predetermined information on the operation panel 40 may be performed as the display return process. In the case of this configuration, for example, when the operation is performed on the call key 46 in the power saving mode and then the start key 44 is operated, the selection function indicated by the called setting program is displayed. Only information related to the above (corresponding to the second predetermined information) is displayed on the operation panel 40, and the printing unit 10 is caused to perform printing. For example, the contents of the selected function and the registered set value may be displayed as information regarding the selected function.

When the operation performed on the operation panel 40 in the power saving mode is neither the first operation nor the second operation, the control unit 110 performs only display return processing. That is, in this case, the multifunction peripheral 100 is in the power saving display mode.

Hereinafter, a flow of processing performed when the operation panel 40 receives an operation in the power saving mode will be described with reference to a flowchart shown in FIG. The flowchart shown in FIG. 8 starts when the operation panel 40 receives an operation in the power saving mode. When the operation panel 40 accepts an operation in the power saving mode, the control unit 110 displays the setting screen 410 set as the initial screen among the plurality of setting screens 410 on the operation panel 40 by performing a display return process. Let

In step S1, the control unit 110 determines whether or not the document D to be read is set on the multifunction peripheral 100 based on the output value of the set sensor SS. As a result, when the control unit 110 determines that the document D to be read is set in the multifunction peripheral 100, the process proceeds to step S2, and control is performed if the document D to be scanned is not set in the multifunction peripheral 100. When the unit 110 determines, this flow ends.

When the process proceeds to step S2, the control unit 110 determines whether or not the operation performed in the power saving mode (the operation serving as the start trigger for the display return process) is the first operation. That is, the control unit 110 determines whether or not a pressing operation on the start key 44 has been performed. As a result, when the control unit 110 determines that the operation performed in the power saving mode is the first operation (pressing operation on the start key 44), the process proceeds to step S3.

When the process proceeds to step S3, the control unit 110 performs a main body return process. In step S4, the control unit 110 recognizes the function corresponding to the setting screen 410 set as the initial screen as the target function (used function), and sets the setting value of the target function to the default setting value.

Thereafter, in step S5, the control unit 110 determines whether or not the job execution unit 100J has returned to the job ready state. As a result, when the control unit 110 determines that the job execution unit 100J has returned to the job ready state, the control unit 110 determines that the job execution unit 100J has not returned to the job ready state. If so, the determination in step S5 is repeated.

In step S6, the control unit 110 causes the job execution unit 100J to execute the job of the target function. At this time, the job execution unit 100J executes the job under an execution condition corresponding to the default setting value.

In step S2, when the control unit 110 determines that the operation performed in the power saving mode (the operation that has been a trigger for starting the display restoration process) is not the first operation, the process proceeds to step S7. In step S7, the control unit 110 determines whether or not the operation performed in the power saving mode is the second operation (pressing operation on either the numeric keypad 45 or the call key 46). As a result, if the control unit 110 determines that the operation performed in the power saving mode is the second operation, the process proceeds to step S8, and the operation performed in the power saving mode is not the second operation. When the unit 110 determines, this flow ends.

When the process proceeds to step S8, the control unit 110 recognizes the target function. In addition, the control unit 110 sets a setting value for the target function.

At this time, when a pressing operation on the numeric keypad 45 is performed as the second operation, the control unit 110 recognizes the copy function as a target function, and sets the number of copies to be set as the number of copies to be printed by the numerical value input by the pressing operation on the numeric keypad 45. Process. On the other hand, when the pressing operation is performed on the call key 46 as the second operation, the control unit 110 recognizes the selection function indicated by the setting program corresponding to the call key 46 that has received the pressing operation as the target function, and Call processing for setting the set value of the selected function recognized as a function to the registered set value is performed.

Thereafter, in step S9, the control unit 110 determines whether the start key 44 has been pressed before the unused time in which the MFP 100 has not been used exceeds the predetermined threshold time after the second operation is performed. Judge whether or not. As a result, if the control unit 110 determines that the start key 44 has been pressed before the unused time exceeds the predetermined threshold time, the process proceeds to step S10, and the start key until the unused time exceeds the predetermined threshold time. When the control unit 110 determines that 44 is not pressed, this flow ends.

When the process proceeds to step S10, the control unit 110 performs a main body return process. Thereafter, the process proceeds to step S5. When the process proceeds from step S10 to step S6 via step S5, the control unit 110 causes the job execution unit 100J to execute the job of the target function. At this time, if the second operation is a pressing operation on the numeric keypad 45, the job execution unit 100J executes a copy job. That is, the printing unit 10 performs printing for the number of copies set by the copy number setting process by the control unit 110 (for the number of copies corresponding to the numerical value input by pressing the numeric keypad 45). When the second operation is a pressing operation on the call key 46, the job execution unit 100J performs a job of a selection function indicated by the setting program called by the control unit 110 according to the registered setting value indicated by the setting program. Execute under the specified execution conditions.

As described above, the multifunction peripheral 100 (image forming apparatus) of the present embodiment is an image forming apparatus equipped with a normal mode (first mode) and a power saving mode (second mode) that consumes less power than the normal mode. In the normal mode in which the power supply unit 120 that supplies power and the image reading unit 20 that reads the document D and generates image data of the document D and receives the normal power supply from the power supply unit 120, the image reading unit 20 In the power saving mode in which the power supply from the power supply unit 120 is restricted as compared with that in the normal mode, the job execution unit 100J that does not execute the job is waited for in a job-ready state where the job accompanying the reading of the document D by In the normal mode in which normal power supply from the power supply unit 120 is received, the user's operation is accepted while the screen is displayed. The power saving mode in which power supply is limited than the normal mode, an operation panel 40 to accept user operations without the display screen, and a control unit 110. The operation panel 40 has a start key 44 that is a hardware key 42 for accepting a job execution instruction from a user, and the control unit 110 performs operations when the start key 44 is operated in the power saving mode. When a normal power supply is performed from the power supply unit 120 to the job execution unit 100J, a main body return process (recovery process) for returning the job execution unit 100J to a job ready state is performed, and the job execution unit 100J returns to a job ready state. The job execution unit 100J is caused to execute a job.

In the configuration of the present embodiment, when the start key 44 is operated in the power saving mode, the job execution unit 100J returns to the job ready state without performing the operation again on the start key 44 thereafter. The job execution unit 100J that has returned to the job ready state executes the job. That is, if the operation performed in the power saving mode is an operation on the start key 44, the operation is accepted as a job execution instruction. Therefore, when the user instructs the MFP 100 to execute a job, even if the MFP 100 is in the power saving mode at that time, the user only needs to perform an operation on the start key 44 once. Execution can be instructed. Thereby, since it is not necessary to perform operation with respect to the operation panel 40 many times, a user's convenience improves.

Further, in the conventional configuration, when the image forming apparatus is in the power saving mode, the operation panel does not display a screen on the operation panel by performing some operation on the operation panel. Cannot instruct execution. Therefore, it is necessary for the user to wait until a screen is displayed on the operation panel (a waiting time occurs). On the other hand, in the configuration of the present embodiment, since the operation on the start key 44 performed in the power saving mode (when the screen is not displayed on the operation panel 40) is accepted as a job execution instruction, no waiting time occurs. . As a result, the multifunction peripheral 100 can promptly start a job.

In the present embodiment, the control unit 110 sets the number of copies to set the numeric value input by the operation on the numeric keypad 45 when the numeric keypad 45 (numeric input key) is operated in the power saving mode. When the operation is performed on the start key 44 after that, the main body is restored, and the image reading unit 20 that has returned to the job ready state is caused to read the original D, and the printing that has returned to the job ready state is performed. The set 10 is caused to print the number of copies set in the copy setting process. In this configuration, when the multifunction device 100 is in the power saving mode (when the screen is not displayed on the operation panel 40), when an operation is performed on the numeric keypad 45, the numerical value input by the operation is used as the number of copies. Is set. For this reason, when the user wants to set the desired number of copies, even if the multifunction device 100 is in the power saving mode at that time (even if the screen is not displayed on the operation panel 40), the operation panel 40 The user does not have to wait for the screen to appear. Furthermore, when the operation performed when the multifunction peripheral 100 is in the power saving mode is an operation on the numeric keypad 45, the copy function is recognized as a target function (used function). That is, when the operation on the start key 44 is continued after the operation of the numeric keypad 45, the multi-function device 100 executes a copy job. Therefore, it is not necessary for the user to select a function to be used. This further improves user convenience.

In the present embodiment, the control unit 110 performs a calling process for setting the setting value of the selection function to the registered setting value when an operation is performed on the calling key 46 in the power saving mode, and then the start key. When an operation is performed on the main unit 44, a main body return process is performed, and the job execution unit 100J that has returned to the job ready state is caused to execute a job that uses the selection function. In this configuration, when the multifunction device 100 is in the power saving mode (when the screen is not displayed on the operation panel 40), if the operation is performed on the call key 46, the setting program is called. For this reason, when the user wants to call a desired setting program (when a job that uses the selection function is executed under an execution condition corresponding to the registered setting value), even if the MFP 100 is in the power saving mode at that time. The user does not need to wait until the screen is displayed on the operation panel 40 (even if the screen is not displayed on the operation panel 40). This further improves user convenience.

In the present embodiment, the control unit 110 performs a main body restoration process when an operation is performed on the start key 44 in the power saving mode, and corresponds to the setting screen 410 set as an initial screen among a plurality of types of functions. The job execution unit 100J that has returned to the job ready state is caused to execute a job that uses the function to be performed (designated function). In this configuration, the job to be executed can be switched by operating the start key 44 in the power saving mode only by changing the setting on the setting screen 410 displayed as the initial screen.

In the present embodiment, the control unit 110 determines whether or not the document D to be read is set in the multifunction peripheral 100 based on the output value of the set sensor SS when the start key 44 is operated in the power saving mode. If the document D to be read is not set, the main body restoration process is not performed (that is, the job is not executed). With this configuration, it is possible to suppress the inconvenience that the job is executed even when the document D to be read is not set on the multifunction peripheral 100 (suppress the execution of a useless job). can do).

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the description of the above-described embodiment but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

For example, in the above embodiment, when the multifunction device 100 is activated (including when the multifunction device 100 returns from the power saving mode to the normal mode), the user-specified setting screen 410 is displayed on the operation panel 40 as an initial screen. However, instead of the setting screen 410, as shown in FIG. 9, a predetermined home screen 420 may be displayed on the operation panel 40 when the MFP 100 is activated.

Although not particularly limited, the home screen 420 displayed on the operation panel 40 when the MFP 100 is started up has functions used from a plurality of functions (copy function, box function, and transmission function) installed in the MFP 100. A function selection key 421 that is a software key for receiving a selection instruction from the user is arranged. In addition, the home screen 420 is an area corresponding to a user-specified designation function among a plurality of types of functions, and operations related to the designation function (for example, an operation for setting a setting value of the designation function and a job using the designation function are executed. An operation table area 422 that is an area for receiving an operation) is arranged. In FIG. 9, as an example, a home screen 420 on which an operation area 422 corresponding to the copy function (an area for accepting a setting of the number of copies and an instruction to execute a copy job from the user) is illustrated.

In such a configuration, when the first operation (pressing operation on the start key 44) is performed on the operation panel 40 in the power saving mode, the control unit 110 performs the main body restoration process as in the above embodiment. . In addition, the control unit 110 recognizes the target function. At this time, the control unit 110 recognizes a function corresponding to the operation area 422 arranged on the home screen 420 as a target function. Then, when the job execution unit 100J returns to the job ready state, the control unit 110 causes the job execution unit 100J to execute the job of the target function (function corresponding to the operation area 422).
